Description

A throwing lifesaving device

technical field

The utility model relates to a life-saving device, in particular to a throwing type life-saving device.

Background technique

Water operations and rescue of people who fall into the water are activities with certain risks, especially in China, where increasingly frequent drowning tragedies have become a permanent pain in people's hearts. Most of the current marine lifebuoys are made of foamed plastics, which are relatively large in size. When a person falls into the water, if the rescue ship is far away from the person who fell into the water, it is often difficult to achieve the purpose of rescue by throwing the lifebuoy at a long distance due to the high resistance in the air. The best rescue opportunities are often lost, resulting in irreparable consequences. There are also life-saving devices that can be rescued as long as they are quickly inflated and then thrown into the water. However, due to the influence of air resistance, the throwing distance of this lifebuoy is often limited, so it can only meet the use of people who fall into the water at close range.

Contents of the invention

The technical problem to be solved by the utility model is a long-distance throwing lifesaving device that can be automatically inflated when encountering water.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a throwing lifesaving device, including a gas cylinder and a life-saving airbag. The gas cylinder is fixedly connected with a valve body, and a thimble is arranged in the valve body. The needle point of the thimble is facing the bottle mouth of the gas cylinder, a sealing film is arranged on the bottle mouth of the gas cylinder, and an inflation hose is fixedly connected between the rescue air bag and the valve body. The thimble is provided with a vent hole for connecting the gas cylinder and the inflation hose, and the valve body is provided with a self-dissolving elastic driving mechanism for driving the thimble.

The self-dissolving elastic driving mechanism includes a self-dissolving block, a thimble fixing seat and a spring, the thimble fixing seat is fixedly connected with the tail of the thimble, and the self-dissolving block is abutted on the thimble and fixed Between the lower end surface of the seat and the valve body, a water inlet is provided on the side of the valve body corresponding to the position of the self-dissolving block, and a threaded cap is screwed inside the upper end of the valve body, The spring is abutted between the lower end of the threaded cap and the upper end of the thimble fixing seat.

A sealing gasket is provided between the self-dissolving block and the valve body. When the self-dissolving block meets water and autolyzes, the thimble fixing seat is quickly pressed against the sealing gasket under the push of the spring to prevent the gas cylinder from The gas leaks from the water inlet of the valve body.

A guide groove is arranged on the side of the thimble fixing seat, and a transverse set screw is fixedly arranged on the valve body, and the set screw extends into the guide groove.

The valve body is provided with a slider, and the slider is located above the thimble fixing seat, and the spring is connected between the lower end of the threaded cap and the slider. A ball is arranged between the slider and the thimble holder, and an annular groove is arranged on the upper surface of the thimble holder, and the ball is embedded in the ring groove.

Fluorescent powder is coated inside the rescue air bag, so that the rescue device can carry out rescue at night.

Compared with the prior art, the utility model has the advantage that since the valve body is provided with a self-dissolving elastic drive mechanism for driving the thimble, when the self-dissolving sheet meets water and self-dissolves, the thimble breaks the gas cylinder under the push of the spring The gas cylinder quickly inflates the rescue airbag through the vent hole in the thimble and the inflation hose, so that the lifesaving device will automatically inflate when it encounters water, and realize the rescue of people who fell into the water; because the device is in the initial state of the rescue airbag Airless and small in size, in the event of drowning, any person on site can throw the life-saving device near the person who fell into the water at a long or short distance. Tie a stay rope on the life-saving device, which is convenient for rescuers to pull the drowning person back to the shore from the water, and also facilitates rescuers to carry out rescue under certain wind and current conditions, which improves the rescue efficiency; in addition, the entire lifesaving The device has simple structure, low cost, and is easy to disassemble and install.
