It is to be understood that the following text is merely illustrative of one or more specific embodiments of the invention and does not strictly limit the scope of the invention as specifically claimed.

Example 1

As shown in fig. 1 to 18, the present embodiment provides a drainage pump adjusting device for underground cable maintenance, which includes a rack 11000, where the rack 11000 is provided with:

a drain pump 1000 for pumping out the accumulated water;

a roller 2000 rotatably mounted on the upper portion of the frame 11000;

a hanging rope 3000 wound around the outer circumference of the drum 2000 for connecting with the drain pump 1000, and the drain pump 1000 is driven to move up and down by rotating the drum 2000;

the supporting mechanism 4000 is movably mounted at the bottom of the frame 11000 and is in two states, one of which is: avoiding the moving track of the drainage pump 1000; the second is as follows: a work station for supporting the drain pump 1000;

the adjusting mechanism is used for adjusting the bearing mechanism 4000 to be alternately positioned at an avoidance position and a working position;

and the triggering mechanism is used for triggering the adjusting mechanism to adjust the state of the supporting mechanism 4000 along with the lifting of the drainage pump 1000.

The underground cable overhauls uses drain pump adjusting device that this embodiment provided, it drives trigger mechanism through lifting drain pump 1000 and triggers adjusting mechanism and adjusts bearing mechanism 4000 and be in turn and dodge the position, the work position, when bearing mechanism 4000 is in when dodging the position, can dodge the removal orbit of drain pump 1000, be favorable to putting drain pump 1000 down and draw water the operation in the cable well, when bearing mechanism 4000 is in the work position, bearing mechanism 4000 can support the drain pump 1000 of placing it on, play the effect that bears drain pump 1000. Because in the state adjustment process of the bearing mechanism 4000, the lifting of the drainage pump 1000 is utilized to trigger the adjustment action, manual adjustment is not needed through manual participation, the clearance of adjustment operation is reduced, time and labor are saved, the working efficiency is improved, the automation level of the adjustment equipment is improved, and the popularization and the application are facilitated.

The basic working principle of the embodiment is as follows: the hanging rope 3000 is driven to wind on the roller 2000 by rotating the roller 2000, and the drainage pump 1000 is driven to lift by the hanging rope 3000; since the purpose to be achieved by this embodiment is to lift the drainage pump 1000, the supporting mechanism 4000 can be adjusted to be in the avoiding position and the working position alternately, so that the drainage pump 1000 is lowered to the cable for pumping when the supporting mechanism 4000 is in the avoiding position, and the drainage pump 1000 is placed on the supporting mechanism 4000 when the supporting mechanism 4000 is in the working position, a triggering mechanism and an adjusting mechanism are provided, the triggering mechanism can perform triggering actions along with the lifting of the drainage pump 1000 by setting the triggering mechanism, so as to trigger the adjusting mechanism to perform adjusting actions, and the adjusting mechanism adjusts the supporting mechanism 4000 to be switched to the avoiding position or the working position when the adjusting mechanism performs adjusting actions alternately.

As shown in fig. 1 to 5, in order to switch the carriage mechanism 4000 between the escape position and the working position by moving the carriage mechanism with a small stroke, the present embodiment preferably includes: the supporting mechanism 4000 is installed on the frame 11000 in a sliding manner in the horizontal direction, and when the adjusting mechanism adjusts the state of the supporting mechanism 4000, the state switching is realized by adjusting the supporting mechanism 4000 to slide in the horizontal direction. Through this kind of setting, be favorable to reducing the stroke that bearing mechanism 4000 moved, can realize that bearing mechanism 4000 has a lot along the horizontal slip's concrete mode moreover, easily realizes, is favorable to practicing thrift the cost.

On the basis of the above preferred embodiment, since the supporting mechanism 4000 is installed on the frame 11000 in a sliding manner in the horizontal direction, and the drainage pump 1000 is lifted in the vertical direction, when the adjusting mechanism is triggered by the triggering mechanism, the action direction of the triggering force in the vertical direction is firstly adjusted to be consistent with the horizontal direction, so as to adjust the supporting mechanism 4000 to perform the horizontal sliding. In view of the foregoing analysis, the present example provides an embodiment of an adjustment mechanism: as shown in fig. 1 to 5, the adjusting mechanism includes a reversing component 5000 and a transmission component 6000, the reversing component 5000 is connected to the triggering mechanism, the transmission component 6000 is connected to the supporting mechanism 4000, the reversing component 5000 is used for adjusting the acting force applied by the triggering mechanism in the vertical direction to be applied to the transmission component 6000 in the horizontal direction, and the transmission component 6000 is used for adjusting the supporting mechanism 4000 to switch between the avoiding position and the working position. The working principle of the embodiment is as follows: after the adjusting mechanism receives the trigger action force of the trigger mechanism, the action direction of the trigger action force of the trigger mechanism is adjusted by the reversing component 5000 to enable the trigger action force to act on the transmission component 6000 in the horizontal direction, and then the bearing mechanism 4000 is adjusted to be in the avoiding position or the working position through the transmission component 6000.

Because the supporting mechanism 4000 is switched from the working position to the avoidance position by lifting the drainage pump 1000, after the adjusting mechanism adjusts that the supporting mechanism 4000 is in the avoidance position, the drainage pump 1000 is still at a position above the supporting mechanism 4000, and if the drainage pump 1000 needs to be lowered into the cable well from the current position through the avoidance position of the supporting mechanism 4000, a certain time is required, so that the supporting mechanism 4000 needs to be kept at the avoidance position in the time, so that the lowering operation of the drainage pump 1000 is facilitated; in addition, after the drainage pump 1000 finishes the task of pumping out the accumulated water in the well, the drainage pump 1000 needs to be lifted above the supporting mechanism 4000, that is, during the process of lifting the drainage pump 1000 again, the drainage pump 1000 needs to pass through the avoidance position of the supporting mechanism 4000 again, so that the supporting mechanism 4000 needs to be kept at the avoidance position before the triggering mechanism triggers the adjusting mechanism again. Combining the foregoing analysis, the preferred scheme provided by this example is: as shown in fig. 1-5, the adjustment mechanism further includes a locking assembly 7000, the locking assembly 7000 being disposed between the reversing assembly 5000 and the transmission assembly 6000, the locking assembly 7000 being configured to lock the current condition of the racking mechanism 4000 at a gap between two consecutive trigger actuations of the trigger mechanism and unlock the previous condition of the racking mechanism 4000 at the trigger actuation of the trigger mechanism. The working principle of the embodiment is as follows: when the trigger mechanism triggers the adjustment mechanism, the lock unit 7000 unlocks the state of the supporting mechanism 4000, so that the adjustment mechanism performs the adjustment operation to change the state of the supporting mechanism 4000; after the adjusting mechanism performs the adjusting action and before the adjusting mechanism performs the adjusting action again, the state of the supporting mechanism 4000 is locked, so that the supporting mechanism 4000 keeps the current state, and other corresponding operations are performed, for example, the supporting mechanism 4000 is locked at the avoiding position, so that the drainage pump 1000 is put down to the cable well through the avoiding position of the supporting mechanism 4000 to perform the water pumping operation.

The technical purpose of the reversing assembly 5000 is to adjust the vertical force of the trigger mechanism to the horizontal direction and apply the force to the transmission assembly 6000, so as to adjust the state of the supporting mechanism 4000. In order to easily achieve the above technical objectives and save cost, a preferred solution of the present embodiment is: as shown in fig. 1 to 5, the reversing assembly 5000 is formed by a reversing rod 5100 arranged in a vertical manner, the middle part of the reversing rod 5100 is rotatably mounted on the frame 11000 through a rotating shaft 5200, one end of the reversing rod 5100 is movably connected with the triggering mechanism, the other end of the reversing rod 5100 is movably connected with the transmission assembly 6000, and the reversing rod 5100 drives the transmission assembly 6000 to adjust the supporting mechanism 4000 to switch between the avoiding position and the working position when the triggering mechanism is triggered. The principle of the reversing rod 5100 for realizing the technical purpose is as follows: before the trigger mechanism triggers the adjusting mechanism, the reversing rod 5100 is in an inclined state; when the trigger mechanism triggers the adjusting mechanism, one end of the reversing bar 5100 rotates relative to the frame 11000 in one direction due to the trigger action force in the vertical direction, and the other end of the reversing bar 5100 rotates relative to the frame 11000 in the reverse direction of the direction, so that the transmission assembly 6000 is driven to adjust the supporting mechanism 4000 to move, because the supporting mechanism 4000 is installed on the frame 11000 in a sliding manner in the horizontal direction, and the transmission assembly 6000 is driven to adjust the supporting mechanism 4000 to move, the force is a component force of the action force applied by the lower end of the reversing bar 5100 to the transmission bar 6100 in the horizontal direction, and therefore, the transmission bar 6100 is equivalent to adjusting the action force in the vertical direction to the horizontal direction and applying the action force to the transmission bar 6100 to adjust the supporting mechanism 4000 to horizontally slide.

The working principle of the preferred scheme is as follows: the transmission rod 6100 slides in the horizontal direction when receiving the acting force in the horizontal direction applied by the reversing rod 5100, so as to drive the connecting member 6200 to move, and further drive the supporting mechanism 4000 to slide in the horizontal direction; after the supporting mechanism 4000 is moved to the right position, the transmission rod 6100 is locked by the locking assembly 7000, so that the transmission rod 6100 is kept at the current position, and further the supporting mechanism 4000 is kept at the current position, thereby realizing the locking of the state of the supporting mechanism 4000; in addition, the transmission rod 6100 is arranged to be a split structure formed by the transmission rod 6100 and the connecting piece 6200, so that the transmission rod 6100 and the connecting piece 6200 can be transported and assembled separately, later maintenance and replacement are facilitated, and the maintenance cost is reduced.

A fixing support 7120 is arranged below the locking sleeve 7100 and used for fixing the locking sleeve 7100 at the bottom of the stand 11000. The fixed support 7120 and the locking sleeve 7100 can be connected in an integrated structure or in a detachable connection mode, and the detachable connection mode is more preferable, so that parts can be replaced independently, and the maintenance cost is reduced.

Further, as shown in fig. 1 to 16, the driven stud tooth 7300 and the driven rod 6120 may be provided with a split structure, so as to facilitate replacement and reduce maintenance cost, and in the case that the two are split structures, an insertion portion for inserting the driven rod 6120 may be provided on an end face of the driven stud tooth 7300 for connecting with the driven rod 6120, and the insertion portion may be a groove or a tubular member protruding from the end face of the driven stud tooth 7300; of course, it can be understood by those skilled in the art that the driven cylinder teeth 7300 and the driven rod 6120 can be integrated into a single structure, which is beneficial to reduce the number of parts, facilitate the management of parts, and prevent parts from being lost. A split structure can be arranged between the driving column teeth 7200 and the driving rod 6110, or the driving column teeth and the driving rod 6110 are fixedly connected into a whole, and the integrated structure is preferred in the embodiment, so that the driving column teeth and the driving rod are quickly formed during machining and manufacturing.

Furthermore, the middle part of the end surface of the driving stud tooth 7200, which faces the driven stud tooth 7300, extends into the body to form a guide vacancy part, the middle part of the end surface of the driven stud tooth 7300, which faces the driving stud tooth 7200, extends outwards to form a guide protrusion part, and the guide protrusion part and the guide vacancy part form sliding guide fit, so that the driving stud tooth 7200 and the driven stud tooth 7300 are positioned, the driving stud tooth and the driven stud tooth are coaxially matched in the using process, and the driving stud tooth and the driven stud tooth can be prevented from slipping when moving relatively along the axial direction.

As shown in fig. 13 to 16, the guide limit assembly includes a guide portion 7114 of a2 and a C guide portion 7220 mounted on the driving stud 7100, the guide portion 7114 of a2 is formed by extending the root of the half tooth 7112 of a2 into the body of the driving stud in the tooth height direction, the C guide portion 7220 is arranged around the driving stud 7200 at intervals in the circumferential direction, the C guide portion 7220 is arranged corresponding to the guide portion 7114 of a2, the C guide portion 7220 and the guide portion 7114 of a2 form a sliding guide fit and limit the rotation of the driving stud 7200 relative to the locking sleeve 7100, and when the B guide portion 7310 moves to correspond to the guide portion 7114 of a2, the root of the half tooth 7112 of a2 is used for limiting the movement of the B guide portion 7310 along the guide portion 7114 of a 2. The working principle is as follows: the C guide portion 7220 and the a2 guide portion 7114 are provided in order to make the driving stud teeth 7200 slide in the locking sleeve 7100 along the guiding direction of the a2 guide portion 7114 and cannot rotate relative to the locking sleeve 7100; the B half teeth 7311 on the driven column teeth 7300 are engaged with the C full teeth 7210, a1 half teeth 7111 and a2 half teeth 7112 respectively at different times, that is, the driven spur teeth 7300 will continuously change angles, to achieve locking of the driven bar 6120 in different positions, whereas the a2 guide 7114 is located at the root of the a2 half tooth 7112, the a2 guide 7114 needs to be different from the a1 guide 7113 in that the B guide 7310 can only make a sliding guide fit with the a1 guide 7113, and not the a2 guide 7114, i.e., the a2 guide 7114 needs to limit the sliding of the B guide 7310 along the a2 guide 7114, it is thus possible to lock the B half cog 7311 at the root of the a2 half cog 7112, so that when the B half cog 7311 is alternately shifted to the root of the a1 half cog 7111, the root of the a2 half cog 7112, respectively, at different positions along the axial direction of the locking sleeve 7100, thereby achieving position adjustment of the driven rod 6120.

Specifically, as shown in fig. 13 to 16, the a1 guide 7113 is configured by an a1 guide groove, the a2 guide 7114 is configured by an a2 guide groove, the depth of the a1 guide groove in the radial direction of the locking sleeve 7100 is greater than the depth of the a2 guide groove in the radial direction of the locking sleeve 7100, the B guide 7310 is configured by a B guide block disposed on the periphery of the driven stud 7300, when the B guide block moves to correspond to the a2 guide groove, the tooth root of the a2 half tooth 7112 abuts against the B guide block and restricts the B guide block from sliding along the a2 guide groove, the C guide 7220 is configured by a C guide block mounted on the periphery of the driving stud 7200, and the C guide block is slidably engaged with the a2 guide groove.

Of course, it will be understood by those skilled in the art that the a1 guide slots can be provided as through slots through the wall of the locking sleeve 7100, while the a2 guide slots open only on the inner wall of the locking sleeve 7100, as shown in fig. 16. Therefore, on one hand, the locking sleeve 7100 is convenient to process and manufacture, and on the other hand, the driven column teeth 7300 are convenient to rapidly position during assembly and disassemble during maintenance.

In order to make the return direction of the driven stud tooth 7300 coincide with the axial direction of the locking sleeve 7100, it is preferable that the return assembly 8000 is formed of a compression spring, the compression spring is sleeved on the periphery of the driven rod 6120, one end of the compression spring is connected to the driven stud tooth 7300, and the other end is connected to the frame 11000, and the compression spring is used for driving the driven stud tooth 7300 to move toward the side close to the driving stud tooth 7200 along the axial direction of the locking sleeve 7100.

In specific implementation, the triggering mechanism comprises a follow-up triggering component and a driven triggering component, the follow-up triggering component is assembled on the lifting rope 3000 and/or the drainage pump 1000 and can move up and down along with the lifting rope 3000 and/or the drainage pump 1000, the driven triggering component is movably installed on the rack 11000 and is connected with the follow-up triggering component in an abutting mode, and the follow-up triggering component can move against the driven triggering component when rising and can trigger the adjusting mechanism to adjust the state of the supporting mechanism 4000 through the driven triggering component. The principle is as follows: the follow-up trigger assembly is used for realizing follow-up rising when the drainage pump 1000 rises, and the follow-up trigger assembly is an intermediate part for establishing a linkage relation between the follow-up trigger assembly and the adjusting mechanism and is used for triggering the adjusting mechanism to implement adjusting action when the follow-up trigger assembly abuts against and moves.

Since the technical purpose of the reversing assembly 5000 in the adjusting mechanism is to adjust the trigger acting force in the vertical direction to the horizontal direction, the driven trigger assembly, as an associated component of the follow-up trigger assembly and the adjusting mechanism, should be lifted when being abutted by the follow-up trigger assembly, so that the reversing assembly 5000 in the adjusting mechanism is acted by the acting force in the vertical direction. The preferred scheme of the embodiment is as follows: as shown in fig. 1 to 5, the follow-up trigger assembly is composed of a trigger 9000, and the trigger 9000 is assembled on a lifting rope 3000; driven trigger assembly constitutes for lift member 10000, and lift member 10000 slides along vertical direction and installs on frame 11000, and lift member 10000 rises when receiving trigger 9000 to support to lean on. The principle is as follows: trigger 9000 can be along with the ascending and lifting of drain pump 1000 to can lean on lifter 10000 and upwards slide, lifter 10000 triggers adjustment mechanism when rising, makes switching-over subassembly 5000 among the adjustment mechanism receive along vertical direction's effort.

When the lifting rod 10000 and the reversing rod 5100 are actually assembled, a connecting rod is respectively connected with the lifting rod 10000 and the reversing rod 5100 through pivots. In addition, in order to prevent the link from interfering with the frame 11000 during the up and down movement of the up-down rod member 10000, an end portion of the up-down rod member 10000 may be extended to the outside of the frame 11000 in the rod length direction to form a connection portion for connecting the link. More preferably, the end of the lifting rod 10000 extending to the outside of the frame 11000 is bent downward to form a bent portion, and the bent portion is used as a connecting portion for connecting a connecting rod, so that it is more beneficial to increase the avoiding space and prevent interference, as shown in fig. 1 to 5.

Because the lifting rope 3000 is in the rising or falling process of the drainage pump 1000, usually the lifting rope 3000 will rise or fall along with it, and before the trigger 9000 does not contact the lifting rod 10000, the lifting rope 3000 inevitably interferes with the lifting rod 10000, so that the interference between the lifting rope 3000 and the lifting rod 10000 is avoided, and the service lives of the rope and the lifting rod 10000 are prolonged. The preferred scheme of this embodiment is: as shown in fig. 1 to 3, the lifting rod 10000 is a horizontal bar arranged horizontally, and the lifting rod 10000 has an a-shaped gap 10100 through which a lifting rope 3000 can move; trigger 9000 is located the below of lift member 10000, and it is used for driving lift member 10000 lifting when lifting rope 3000 moves up. The principle is as follows: through setting up A vacancy portion 10100 for lifting rope 3000 is in the rise and move down the in-process, can move about from top to bottom in A vacancy portion 10100, in order to prevent to take place to interfere between with lift member 10000.

Since the hanging rope 3000 is wound or released on the drum 2000 while being translated in the axial direction of the drum 2000 in the ascending or descending process of the drain pump 1000, the service lives of the rope and the lifting rod 10000 are prolonged in order to further avoid interference between the hanging rope 3000 and the lifting rod 10000. The more preferable scheme of the embodiment is as follows: as shown in fig. 3, the a-space 10100 is a strip-shaped hole, and the length direction of the strip-shaped hole is consistent with the direction in which the lifting rope 3000 moves relative to the lifting rod 10000 in the horizontal direction.

In order to make the ascending and descending rod 10000 more stable and not generate lateral deviation in the process of moving up and down relative to the frame 11000, the embodiment further prefers to: the frame 11000 is provided with a vertical guide rod 11100 which forms sliding guiding fit with the lifting rod member 10000.

In order to make the state switching of the supporting mechanism 4000 faster and more efficient, a more preferable scheme of the present embodiment is: as shown in fig. 1 to 5, the two sets of the supporting mechanisms 4000 are provided, the two sets of the supporting mechanisms 4000 move in directions away from or close to each other when the adjusting mechanisms are adjusted, and the adjusting mechanisms are provided in two sets and arranged corresponding to the two sets of the supporting mechanisms 4000 respectively. The principle is as follows: switch to dodging the position through adjusting two sets of bearing mechanism 4000 and keeping away from the realization each other, switch to the work position through adjusting two sets of bearing mechanism 4000 and being close to the realization each other, owing to at the switching in-process of state, two sets of bearing mechanism 4000 shift simultaneously, can effectively reduce single bearing mechanism 4000's stroke to be favorable to improving the shift efficiency, and then improve the efficiency that the state switched.

As shown in fig. 1 to 5, in the embodiment, the supporting mechanism 4000 is preferably implemented as follows: the support mechanism 4000 includes a horizontally disposed support plate 4100 and a slider 4200 fixedly attached to the support plate 4100. the frame 11000 is provided with a guide 11200 for slidably guiding the slider 4200. the top surface of the support plate 4100 forms a support 4110 for supporting the drain pump 1000. an adjustment mechanism is attached to the support plate 4100 and adjusts the support plate 4100 to move along the guide 11200. In particular, the method comprises the following steps of,

further, as shown in fig. 1 to 5, the supporting portion 4110 is provided with a limiting member 4111 adapted to the bottom of the drain pump 1000, the limiting member 4111 is used to prevent the drain pump 1000 from moving relative to the supporting portion 4110 along the horizontal direction when the supporting mechanism 4000 is in the working position, the slider 4200 is fixedly disposed at two ends of the bottom of the supporting plate 4100, and the guide rail 11200 is correspondingly provided at two positions.

As shown in fig. 4, specifically, the limiting member 4111 includes an a1 limiting plate 4111a and an a2 limiting plate 4111B disposed at two ends of the a1 limiting plate 4111a, so that the two groups of supporting plates 4100 have two groups of limiting members 4111, the a1 limiting plates 4111a and the a2 limiting plate 4111B are both plate-shaped, and the bottom of the drainage pump 1000 is provided with two B limiting plates 1100 disposed oppositely. When the supporting mechanism 4000 is in the working position, the a1 limiting plate 4111a is positioned between the two B limiting plates 1100 for limiting the movement of the water discharge pump 1000 along the direction of the distance between the two B limiting plates 1100, and the B limiting plate 1100 is positioned between the two a2 limiting plates 4111B for limiting the movement of the water discharge pump 1000 along the length direction of the a1 limiting plate 4111 a; when the bearing mechanism 4000 is switched to the avoidance position, the drainage pump 1000 is lifted first, so that the limiting part 4111 can relieve the limitation of the drainage pump 1000, and the bearing mechanism 4000 can be switched to the avoidance position to avoid the movement of the drainage pump 1000.

Further, as shown in fig. 5, the bottom of the housing 11000 has a vacant area 11300 through which the drain pump 1000 moves, and the vacant area 11300 is formed by the movement of the supporting mechanism 4000 to the evacuation position. The vacant area 11300 is arranged, so that the drainage pump 1000 can move through the vacant area, the downward operation of the drainage pump 1000 is realized, when the supporting mechanism 4000 is in the working position, the supporting mechanism 4000 is in a position corresponding to the vacant area 11300 and provides a supporting effect for the drainage pump 1000, and therefore the drainage pump 1000 is prevented from falling; when the support mechanism 4000 is in the avoiding position, the vacant area 11300 is exposed, and the support function of the support mechanism 4000 is lost by the drain pump 1000, so that the support mechanism 4000 is prevented from interfering with the movement of the drain pump 1000, and the lowering operation of the drain pump 1000 is facilitated.

As the equipment often needs to be transferred to a different wireline well in order to perform service operations on the different wireline well. Therefore, in order to move the device conveniently, improve the working efficiency and reduce the labor intensity, the embodiment further preferably adopts the following scheme: the bottom of the frame 11000 is mounted with rollers 11400 that facilitate movement of the frame 11000.

It will be appreciated by those skilled in the art that since the apparatus is capable of performing a draining operation on the accumulated water in the well, the apparatus may also be applied to other inspection wells, such as sewer wells, catch-basin wells, etc., to perform the draining task on the accumulated water in the well, and is not limited to the cable well described in this embodiment.

Example 2

As shown in fig. 19 to 24, the present embodiment further provides an adaptive locking device for adjusting the lift of a drain pump based on embodiment 1, which includes a rack 11000, wherein the rack 11000 is provided with:

the roller 2000 is rotatably arranged on the frame 11000, and the roller 2000 is driven by a driving force to rotate;

a hanging rope 3000 wound around the outer circumference of the drum 2000 for connecting with the drain pump 1000;

the automatic locking mechanism 12000 is configured to sense or detect a driving force applied to the roller 2000 or a change of a parameter related to the driving force in real time, and adjust the roller 2000 to be in a locked state or a normal rotation state according to the change, where the driving force is a resultant force of forces for driving the roller 2000 to rotate.

Adopt the self-adaptation locking means for drain pump lift adjustment that this embodiment obviously provided, can respond to in real time or detect the drive power that roller 2000 received or with the change of drive power relevant parameter, and according to the change adjusts roller 2000's locking state for it is more convenient high-efficient to adjust the operation, moreover, still is favorable to preventing that drain pump 1000 from hurting operating personnel because of descending rapidly, has improved the security of equipment in the use.

Specifically, the automatic locking mechanism 12000 is configured to sense a change in centrifugal force in real time, and adjust a locking state of the roller 2000 according to the change, where the centrifugal force is a centrifugal force at a certain position on the roller 2000 or a certain position related to the roller 2000 when the roller 2000 rotates. The working principle is as follows: when the roller rotates, a centrifugal acting force can be sensed at a certain position on the roller, the centrifugal force is larger when the rotating speed of the roller 2000 is higher, and the centrifugal force indirectly reflects the rotating speed of the roller 2000 and the change of the driving force borne by the roller 2000; similarly, if some part of other components related to the roller 2000 can sense the change of the centrifugal force caused by the rotation of the roller 2000, the change can also be used as the basis for adjusting the locking state of the roller 2000; the greater the centrifugal force is, the greater the rotation speed of the drum 2000 is, and the greater the descending speed of the drain pump 1000 is indirectly reflected, so that the locking state of the drum 2000 is timely adjusted according to the change of the centrifugal force, and the safe and stable operation of the equipment is facilitated.

The preferred scheme of this embodiment is: as shown in fig. 21, 22 and 24, the automatic locking mechanism 12000 includes a rotating disc 12100 and a movable assembly movably mounted on the rotating disc 12100, the rotating disc 12100 is in transmission connection with the roller 2000, the rotating disc 12100 is driven to rotate when the roller 2000 rotates, and the movable assembly is used for sensing the change of centrifugal force and adjusting the locking state of the roller 2000 according to the change. The principle is as follows: when the rotating disk 12100 rotates with the roller 2000, the movable assembly senses a change in centrifugal force in real time, thereby adjusting the locked state of the roller 2000 according to the change.

More preferably, as shown in fig. 21 to 23, the automatic locking mechanism 12000 further includes a braking component, the braking component is mounted on the frame 11000, the movable component and the braking component are arranged correspondingly, the movable component is used for sensing a centrifugal force applied to the movable component and moving to a position forming a locking fit with the braking component when the centrifugal force applied to the movable component is greater than a binding force applied to the movable component, so that the roller 2000 is in a locking state; when the centrifugal force applied to the movable assembly is smaller than the binding force applied to the movable assembly, the movable assembly and the brake assembly are arranged in a staggered mode, so that the roller 2000 is in a normal rotating state. The principle is as follows: when the centrifugal force borne by the movable assembly is small, the movable assembly is staggered with the brake assembly under the action of the self-borne constraint force, the rotating disc 12100 can rotate relative to the brake assembly, and the roller 2000 can also normally rotate; when the centrifugal force induced by the movable assembly is sufficiently large and can overcome the restraining force applied to the movable assembly, the movable assembly moves to a position where it forms a locking engagement with the brake assembly, such that the turntable 12100 stops rotating relative to the brake assembly and the roller 2000 stops rotating, thereby adjusting the roller 2000 to a locked state.

As shown in fig. 21, 22 and 24, in the preferred embodiment, the movable assembly includes a movable element 12200 and an elastic restoring element, the movable element 12200 is movably mounted on the rotating disc 12100 through the elastic restoring element, the braking assembly is disposed outside the movable element 12200, and the elastic restoring element is configured to provide an elastic binding force for binding the movable element 12200 to move outside the rotating disc 12100; when the centrifugal force applied to the movable member 12200 is greater than the elastic restraining force provided by the elastic restoring member, a portion of the movable member 12200 moves out relative to the rotating disc 12100 and forms a locking engagement with the braking assembly, so that the roller 2000 is in a locked state. The principle is as follows: when the centrifugal force applied to the moving piece 12200 is small, the moving component is staggered with the brake component under the action of elastic binding force, and at the moment, the roller 2000 can normally rotate; when the centrifugal force applied to the moving member 12200 is greater than the elastic binding force, a part of the moving member 12200 moves out relative to the rotating disc 12100 and forms locking cooperation with the brake assembly, so that the rotating disc 12100 and the roller 2000 stop rotating, and the roller 2000 is locked.

Since the technical purpose to be achieved by the brake assembly is to form a locking fit with the movable member 12200 to adjust the roller 2000 to be in a locking state, regarding the structure of the brake assembly for directly performing the locking fit with the movable member 12200, the preferred solution of this embodiment is: as shown in fig. 21 to 23, the braking assembly has a latch 12300, and the latch 12300 is configured to form a locking engagement with a portion of the movable member 12200.

As will be understood by those skilled in the art, the latch 12300 may be one or more, and in order to enable the brake assembly to rapidly adjust the locking state of the roller 2000, it is more preferable that: as shown in fig. 21 to 23, the brake assembly includes a ring gear, an outer circumferential ring of which is formed with a flange mounting portion extending radially outward for fixedly mounting the ring gear on the frame 11000 by bolts, the ring gear being disposed concentrically with the rotating disk 12100, and the latch 12300 being disposed circumferentially at intervals around an inner ring of the ring gear; the movable piece 12200 is formed by movable claws that are matched with the ring gear, and when the centrifugal force applied to the movable claws is larger than the elastic binding force provided by the elastic reset piece, the movable claws are moved out relative to the rotating disc 12100 and engaged with the ring gear, and the roller 2000 is in a locked state. The principle is as follows: because the latch 12300 is arranged at the inner circumference of the ring gear at intervals, when the centrifugal force induced by the moving member 12200 is greater than the elastic binding force, the local part of the moving member can timely form locking cooperation with the closest latch 12300, so that the roller 2000 can be quickly adjusted to the locking state.

As shown in fig. 21-23, the ring gear can be replaced by an internal ratchet wheel, and the movable jaw can be a pawl matched with the internal ratchet wheel.

In specific implementation, as shown in fig. 24, one end of the movable claw is formed by a claw portion, the other end of the movable claw is connected with a rotating disc 12100 through an elastic resetting member, a B-shaped gap portion 12110 for storing the movable claw when the movable claw is reset is arranged on the rotating disc 12100, when the centrifugal force applied to the movable claw is greater than the elastic constraint force provided by the elastic resetting member, the claw portion of the movable claw moves out relative to the rotating disc 12100 and is engaged with the ring gear, so that the roller 2000 is in a locked state, the B-shaped gap portion 12110 is further used for limiting the movable claw to rotate relative to the rotating disc 12100 along the direction of the reaction force of the ring gear when the roller 2000 is in the locked state, that is, the B-shaped gap portion 12110 has an effect of limiting the movable claw when the movable claw moves to be engaged with the ring gear, which is beneficial to ensuring reliable engagement of the movable claw and the ring gear, so as to adjust the locked state of the roller 2000.

Since the change of centrifugal force is related to the rotation speed of the roller 2000 transmitted to the rotating disc 12100, in order to adjust the roller 2000 to be in the locked state at different rotation speeds, the preferred solution of this embodiment is: the device also comprises a speed change assembly, and the speed change assembly is used for adjusting the rotating speed ratio of the roller 2000 to the rotating disc 12100.

The more preferable scheme of the embodiment is as follows: the speed change assembly is used for adjusting the rotating speed ratio of the roller 2000 to the rotating disc 12100 to be less than 1, namely, the rotating speed of the roller 2000 is amplified and then transmitted to the rotating disc 12100, so that the movable piece 12200 can quickly respond and adjust the roller 2000 to a locking state, and the roller 2000 is prevented from quickly descending for a large stroke due to the loss of driving force.

Specifically, the speed change assembly is formed by a speed change gear. Of course, it will be appreciated by those skilled in the art that the implementation of the transmission assembly may be other forms as long as the adjustment of the rotational speed is achieved.

When the elastic reset piece is specifically implemented, the elastic reset piece is one of a torsion spring, a tension spring and a leaf spring.

Regarding the installation mode of the movable member 12200, the preferred solution provided by this embodiment is: movable member 12200 is pivotally or slidably mounted on turntable 12100.

In order to further improve the efficiency of adjusting the locking state of the roller 2000 and ensure the reliability of locking, the preferred scheme of the embodiment is as follows: as shown in fig. 22 and 24, movable members 12200 are arranged on rotating disc 12100 at intervals circumferentially of rotating disc 12100. Therefore, when the movable piece 12200 is in locking fit with the latch 12300, the latch 12300 can form locking fit with the closest movable piece 12200, so that the roller 2000 can be quickly adjusted to the locking state; in addition, if the latch 12300 is a structure that is arranged on the inner circumference of the ring gear at intervals, the efficiency of adjusting the roller 2000 to the locking state and the reliability of locking matching can be greatly improved.
