Description

A kind of power lifebuoy

Technical field

The utility model relates to lifesaving appliance technical field more particularly to a kind of power lifebuoys.

Background technique

Lifebuoy is a main species in the most common water survival gear and lifesaving appliance, typically as water Security protection essential product in the upper disaster relief and associated production business process.Lifebuoy usually by cork, foamed plastics or other The lesser lightweight material of specific gravity is made, and canvas, plastics etc. are wrapped in outside.The shape of lifebuoy is ring-type, middle opening, user Upper body is passed through into middle opening and both hands are ridden on cyclic annular lifebuoy, so that it may utilize the buoyancy of lifebuoy in the state of loosening It swims on the water surface.Lifesaving coil structures currently on the market are simple, be only capable of providing for user corresponding buoyancy so that it will not Sink, has a single function, using limited.

Nowadays swimming becomes a kind of motion mode prevailing, however has every year largely dead because drowned or rescuing drowning man People, because drowning people is for the instinct of emergency, temerarious can catch or embrace rescue wherein including many deliverers The National People's Congress of people, rescue mostly drown because of being short of physical strength.Existing lifebuoy requires manually or mechanically to shed to overboard Person carries out lifesaving at one's side, if encountering unexpected drowned accident, just can guarantee when only drowning people is close from the people of rescue by Lifebuoy is thrown to drowning people at one's side, is otherwise difficult lifebuoy being accurately thrown into the location of drowning people；On the other hand, even if Salvor is opened to apart from the closer place of drowning people and sheds lifebuoy, also will receive the restriction of environmental factor, if live ring Border is unfavorable for the navigation of salvor and accurately shedding for lifebuoy, then extremely influences rescue work；And when drowning people's quantity is more When, it needs to employ a large amount of salvor and manpower, is rescued one by one, not only rescue process is slow, seriously affects drowning people's Life security, and the process need to expend a large amount of human and material resources.Therefore existing lifebuoy can not accomplish that safety timely carries out It sues and labours, it is difficult to ensure the life security of drowning people.

Also there are a small number of lifebuoys for having propulsion device in the prior art, drowning people can be reached by being remotely controlled the lifebuoy Location is sued and laboured, but structure is complicated mostly for such lifebuoy, high production cost, and is short of power, cruise duration It is short, it is difficult to guarantee rescue time and rescue efficiency；When rescue bad environments, such as when water surface stormy waves is larger, the lifebuoy is because of wind Unrestrained overturning of jolting can not continue to navigate by water in switching process, expend energy and delay rescue time；On the other hand, lifesaving Circle needs to be subjected to the pressure of drowning people and the impact force of stormy waves, the lifebuoy with propulsion device, internal propulsion device knot The stability of structure directly affects the reliability of entire lifebuoy, such as the not sufficiently strong stabilization of fruit structure, then after being used for multiple times It is easily damaged, if breaking down in rescue operations, rescue can be seriously affected.

In conclusion a kind of power lifebuoy is needed, to solve above-mentioned technical problem existing for existing lifebuoy.
