Description

An adjustable hydrofoil boat

The present invention relates to an adjustable hydrofoil boat having a balancing device, a hydrofoil and an airbag, so that when the speed of the hydrofoil boat gradually increases, the hydrofoil boat can be lifted up and floated off the water surface, thereby reducing water resistance and increasing the speed.

Early hydrofoil boats often used U-shaped hydrofoils. This type of hydrofoil is called a "semi-submerged" or "cutting" hydrofoil. When flying on a hydrofoil, part of the U-shaped hydrofoil will be immersed in the water, while part will cut through the water surface and appear in the air. The structure of a semi-submerged hydrofoil is relatively simple, and propulsion is generally carried out by a propeller and rudder at the stern that are immersed in the water. Newer hydrofoil boats use inverted T-shaped hydrofoils, which are called "fully submerged" because they often remain underwater. "Fully submerged" hydrofoils are less affected by waves than "semi-submerged" ones, so fully submerged hydrofoils are more stable and comfortable when traveling on rough seas. However, because the fully immersed hydrofoil design does not have the characteristics of self-stabilization, the automatic control system must constantly change the hydrofoil's angle of attack according to the sea surface conditions, hull posture, speed, acceleration and other parameters to maintain the hydrofoil's flying state. Therefore, for a hydrofoil boat with a smaller hull (for example, below 100 horsepower), if it encounters bad weather and bad water conditions, it is very easy to cause poor balance, increased water resistance and uncontrolled speed, and even more prone to capsizing.

The present invention aims to provide a solution to the above-mentioned problems of general hydrofoil boats with lower horsepower.

The present invention aims to provide an adjustable hydrofoil boat, so that a small hydrofoil boat with less than 100 horsepower can increase buoyancy and maintain balance in severe sea conditions, thereby reducing water resistance, increasing speed and improving navigation safety to avoid capsizing, and can be used to cope with complex waves up to 10 meters high.

According to the present invention, an adjustable hydrofoil boat comprises: a hydrofoil boat body; a main engine, which is arranged at the rear of the hydrofoil boat body to supply power; and a balancing device, which is used to maintain the balance and floating of the hydrofoil boat when sailing at high speed, comprising: two sets of motors, which are respectively arranged at approximately equal distances from the center of the boat, each set of motors having a gear and two linear gears. When the motor is started, each gear is driven by the gear to extend linearly to the left and right sides of the hydrofoil boat body and extend out of the boat body to a horizontal folding point. When not in use, each gear is retracted and restored, and the two fixed gears on the left and right sides are fixed. The bracket is connected to the left and right side ends of the two linear teeth, and extends and retracts with the corresponding linear teeth; and four hydrofoils, two on each side are arranged below the fixed bracket, and each hydrofoil is separated by an appropriate distance from the front and back. When the balancing device is activated, each of the two linear teeth extends to the left and right sides respectively and drives the corresponding left and right fixed brackets to extend outward, thereby driving the two left and right hydrofoils to sink, and the speed of the hydrofoil boat gradually increases, so as to provide lift to make the hydrofoil boat float and lift it off the water surface, so as to reduce the resistance of the water and increase the sailing speed. In addition, the present invention can further include at least one air bag, which is arranged on each of the fixed brackets and can be automatically inflated to increase the buoyancy of the hydrofoil boat and prevent it from capsizing when sailing.

Figure 1 shows a schematic diagram of the structure of an adjustable hydrofoil boat of the present invention in use.

As shown in FIG. 1 , according to the present invention, an adjustable double-stern hydrofoil vessel 100 is provided in a state of using a balancing device and a floating design, comprising: a hydrofoil hull 110; a main engine 120, disposed at the rear of the hydrofoil hull, for supplying power; a balancing device (not separately indicated in the figure), for maintaining the balance and floating of the hydrofoil vessel during high-speed navigation, comprising: two sets of motors; 130, 130', respectively, are arranged at approximately equal distances from the center of the boat. Each motor set has a gear 140, 140' and two linear gears 150, 150'. When the motor sets are started, the gears are driven to extend in a straight line to the left and right sides of the hydrofoil hull and extend out of the hull to a horizontal folding point. When not in use, , each tooth retracts to restore, the left and right fixed brackets 180, 180' are respectively connected to the left and right side ends of the two linear teeth, and along with each corresponding linear tooth, extend to the outside of the hydrofoil hull and retract to the edge of the hydrofoil hull, and four hydrofoils 170, two on each side are arranged under the fixed bracket, and each hydrofoil is separated by an appropriate distance from the front and rear, wherein, when the When the balancing device is activated, the two linear teeth extend to the left and right sides respectively and drive the corresponding left and right fixed brackets to extend to the outside of the hydrofoil hull 110, thereby driving the two hydrofoils 170 arranged on both sides of the hull to sink. As the speed of the hydrofoil boat gradually increases, it is used to provide lift to make the hydrofoil hull float and lift it off the water surface, so as to reduce water resistance and increase sailing speed.

The adjustable hydrofoil boat of the present invention may further include a rear hydrofoil 170' disposed behind the hydrofoil boat 110 for adjusting high-speed sailing. In addition, each of the left and right fixed brackets may further be provided with an airbag (190), which is an inflatable soft bag, so that it can be ejected instantly when the hydrofoil boat collides, or can be ejected instantly by the operation of a remote control device. It contains a gas such as carbon dioxide, which is inflated to increase the buoyancy of the hydrofoil boat when sailing. It can be automatically inflated, that is, in the present invention, the distance between the two boats can be determined according to the size of the waves. When there are large aggregate waves (compound waves), in order to reduce the chance of the boat capsizing and turning over, the airbags on the two boats can be automatically inflated to increase floating and avoid capsizing.

Furthermore, when the boat is on the water or stowed, the bracket can be retracted into the hull to avoid collision.

In addition, the adjustable hydrofoil boat of the present invention may further include a foldable soft net 160, which is arranged below the balancing device to allow personnel to move or carry objects on the upper side.

The present invention is particularly applicable to small hydrofoil boats that cannot withstand severe weather conditions. For example, if the power is below 100 horsepower, the present invention can be used for small boats with a main engine of 90 horsepower, and can be used in 10-meter high complex waves to keep the boat stable and not capsize.

Furthermore, the adjustable hydrofoil boat of the present invention may further include a remote control device (not shown in the figure) for controlling the operation of the hydrofoil boat wirelessly or wired. In particular, in the adjustable double-hull hydrofoil boat of the present invention, explosive materials may be pre-set to produce an explosion when the hydrofoil boat hull collides violently, or through the control of the remote control device.

In addition, a nylon rope (200) can be further provided on the outer sides of the left and right fixed brackets 180, 180' of the present invention to facilitate operation.

In short, this invention can not only be used to resist 100-meter-high aggregate waves and maintain the ship's fast and safe navigation, but can also be used in special functions with impact blasting (such as in the form of an unmanned ship).
