Life jacket used by firemen in water areas

Abstract

The invention relates to a life jacket used by firemen in water areas. The life jacket comprises a life jacket body, an inflatable air bag, an inflating life-saving device and an inherently buoyant material, the life jacket body is of a cardigan front type vest structure, the cardigan front is provided with a zipper, the collar of the life jacket body is provided with a pocket, in which the inflatable air bag is arranged, and moreover, one side of the inflatable air bag is connected with the inner wall of the pocket; the back of the lift jacket body is provided with a strip-shaped bag, in which the inflating life-saving device is placed; the inherently buoyant material is arranged inside the life jacket body, the outer walls of both the chest and the waist of the life jacket body are provided with adjusting belts, the ends of the adjusting belts are provided with first Velcros, and correspondingly, the life jacket body is provided with second Velcros. The life jacket has the advantages of reasonable structure, simple wearing and reliable connection; normally, the life jacket can provide moderate buoyancy in order to ensure that a rescuer can agilely swim and operate in water; in an emergency, the life jacket can increase buoyancy to ensure the safety of the rescuer; and consequently, the life jacket has the strong function of saving selves and others, and is suitable for rescuers in water areas.

Description

technical field [0001] The invention belongs to the technical field of water rescue protective equipment, and in particular relates to a lifejacket for firefighters in water area rescue. Background technique [0002] At the scene of floods or other water accidents, it is one of the important tasks of the fire brigade to participate in flood fighting and rescue, rescue those who fell into the water and besieged by water. Lifejackets are necessary equipment for fire brigades to carry out water rescue missions, but there are many problems in existing lifejackets, and cases of rescue failures or casualties of rescuers due to lifejacket problems occur from time to time. To sum up, the current lifejackets mainly have the following problems: [0003] First, the design concepts and requirements of existing lifejackets cannot meet the needs of water rescue work. The design of existing lifejackets is mainly set out from the angle of safety, and buoyancy is mostly concentrated on the...

AI Technical Summary

Problems solved by technology

There are many similar designs, but such lifejackets are not suitable for rescuers to rescue others or work in the water. Fire rescue personnel wearing existing lifejackets are not flexible enough to turn their heads and arms, turn over, and swim in the water, which affects rescue. development of work

[0004] Second, the buoyancy of the life jacket cannot meet the needs of water rescue

The buoyancy of existing lifejackets is generally small, and the buoyancy of ordinary marine work lifejackets is only 73.5N. When fire rescue personnel rescue people in the water, they must wear rescue suits, rescue boots and helmets. Sometimes, especially when the physical strength is weak, there will often be insufficient buoyancy, which is very dangerous for rescuers

More importantly, when rescuers rescue people in the water, they often have to hug the victims and swim or be held tightly by the panicked drowning people. The buoyancy provided by the existing life jackets cannot bear the weight of two people at all. The tragedy in which the rescuers and the rescued died at the same time

However, there is no life jacket that can bear the weight of two adults in the market at present.

China Aviation Industry Standard HB6652-52 "Minimum Performance Requirements for Civil Aircraft Lifejackets" stipulates that the buoyancy of lifejackets used by adults should not be less than 155N. The resistance is relatively large, so it is not suitable for water rescue personnel to use

[0005] Third, the structure of the existing life jacket rope is unreasonable and easy to detach

The existing life jackets are slow to put on and take off, and the wearing comfort is poor. More importantly, the existing life jackets are very easy to separate from the human body in water, and the design of the crotch belt is not humane enough, and it is easy to loosen

In addition, some life jackets have too many straps and buckles on the outer surface, which are very easy to be hooked by rescue tools or underwater objects during rescue, posing a threat to the safety of rescuers.
