Fixed-remote-emission automatic recovery type lifesaving device

Abstract

The invention discloses a fixed-remote-emission automatic recovery type lifesaving device which is characterized by comprising a gas storage bin, a motor bin, an emission bin and a wheel disc bin. A high-pressure gas cylinder and a gas valve switch composed of a movable iron sheet, a fixed iron sheet and a high-strength spring are arranged in the gas storage bin; and a high-power motor, a motor switch and a clutch switch are arranged in the motor bin; the emission bin comprises an emission bin body, a life buoy main body which is filled with hydrophobic foam and is provided with a water inlethole with an elastic valve structure, a wheel disc and a life-saving rope; the wheel disc bin comprises a wheel disc bin body, a rope wheel disc, a clutch connected with the clutch switch and an output bearing. The device is safe, reliable, convenient to rescue, high in rescue efficiency, and free of pollution; the device can be recycled automatically after emission; the occupied area is small; the projection distance is long; and a drowning person can be pulled back to a ship or land.

Description

Technical field: [0001] The invention is a lifesaving device with fixed remote launch and automatic recovery, which belongs to the technical field of rescue equipment on water. Background technique: [0002] The lifebuoy is a kind of water lifesaving equipment, usually made of cork, foam plastic or other light materials with small specific gravity, and covered with canvas, plastic, etc. Life buoys for swimming practice can also be made of rubber and filled with air, also known as rubber rings. [0003] Ordinary lifebuoys are generally pvc plastic filled rings, which are light in weight but not far away, and have poor rescue effects for those who fall into the water far away. Marine lifebuoys are ring-shaped lifesaving equipment made of lightweight solid buoyancy materials, and lifebuoys made of closed-cell foam plastics are common. The use of rushes, cork shavings and cork pellets as buoyancy materials is prohibited on seagoing vessels, nor is the use of inflatable lifebuo...

AI Technical Summary

Problems solved by technology

There are still some problems with this life buoy. First, the structure of the device is relatively inconvenient. The gas cylinder needs to be carried on the back to be used manually. It is not suitable for civilian use. Only professional rescuers can master its use after training. In the process of falling into the water, if it is scratched by sharp objects such as coke rocks, it will fail. There is a great hidden danger in rescue. Another thing is that the warhead can only be fired.
