Water lifesaving device

Abstract

The invention discloses a water lifesaving device comprising a casing and propellers. The two U-shaped sides of the casing are provided with power cabins for accommodating the propellers, and the topsurface and the bottom surface of the casing are respectively provided with water inlets connected with the power cabins; the end of the casing is provided with water outlets communicating with the power cabins; the propellers are arranged in the power cabins, the water suction ports of the propellers are directed toward the water inlets, the water injection nozzles of the propellers are directedtoward the water outlets; the power cabins are provided with supporting devices for supporting the propellers, the outer surface of the propellers are provided with rotating devices, and the rotatingdevices are coupled with the supporting devices, so that the propellers can perform a flipping motion in the power cabins. In the water lifesaving device, the propellers can suck water in multiple directions and provide power to the lifesaving device, so that the lifesaving device can be adapted to different weather conditions for rescue, and the lifesaving device has good power performance, highrescue efficiency, stable and reliable structure, long service life, rich functions and good practicality.

Description

technical field [0001] The invention relates to the technical field of lifesaving devices, in particular to water lifesaving equipment. Background technique [0002] The lifebuoy is the most common water lifesaving equipment, and it is also a major type of lifesaving equipment. It is usually used as a necessary product for safety protection in water disaster relief and related production and operation processes. The life buoys on the market are simple in structure, can only provide corresponding buoyancy for the user so that it will not sink, and have single function and limited use. [0003] Swimming has become a popular sport nowadays. However, a large number of people die every year due to drowning or rescuing people who fell into the water, including many rescuers. Because of the instinct of calling for help, the people who fell into the water will desperately grab or hug rescuers. Most of the people who were rescued drowned due to exhaustion. Existing lifebuoys need t...

Problems solved by technology

Existing lifebuoys need to be manually or mechanically thrown to the side of the drowning person for lifesaving. In case of an accidental drowning accident, only when the drowning person is very close to the rescuer can the lifebuoy be thrown to the side of the drowning person, otherwise it is difficult to put the lifebuoy Accurately throw the life buoy at the location of the person who fell into the water; on the other hand, even if the rescue boat is driven to a place close to the person who fell into the water to throw the lifebuoy, it will be restricted by environmental factors. The accurate throwing of water will greatly affect the rescue work; and when there are many people in the water, it is necessary to use a large number of rescue ships and manpower to rescue them one by one. Not only the rescue process is slow, which seriously affects the life safety of the people in the water. manpower, material resources

Therefore existing buoy buoy can't accomplish rescue in a safe and timely manner, and it is difficult to guarantee the safety of life of those who fall into the water

[0004] In the prior art, there are also a small number of lifebuoys with propulsion devices, which can reach the position of the drowning person for rescue by remote control of the lifebuoy, but most of these lifebuoys have complex structures, heavy and insufficient power, short battery life, and it is difficult to guarantee the rescue time and rescue efficiency, and when the rescue environment is harsh, such as when the water surface is stormy, the lifebuoy will be bumped and flipped due to the wind and waves, and it will not be able to continue sailing during the flipping process, which will consume energy and delay rescue time
