Description

Fireman water rescue life jacket

technical field

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

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:

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 chest, and its purpose is to guarantee the life safety of the person who fell into the water to the greatest extent. Such as patent publication number is that CN101607587A name is called " a kind of lifejacket " Chinese invention patent discloses a kind of lifejacket that design is reasonable, light in weight and can turn over body automatically and keep face upward when people fall into the water. As another example, the patent No. is CN93214217.6 titled "Super Buoyancy Lifejacket" Chinese utility model patent discloses a kind of lifejacket that makes the drowning person keep the upper body at an angle of 45 degrees to tilt out of the water. 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.

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. When, especially when physical strength is weak, the situation of insufficient buoyancy often occurs, and this 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. A tragedy in which the rescuer and the rescued died at the same time. And there is no life jacket that can bear the weight of two adults in the market. 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 received is relatively large, and it is not suitable for water rescue personnel to operate.

The 3rd, existing life jacket cord structure is unreasonable, easily breaks away. Existing lifejackets are slow to put on and take off, and have poor wearing comfort. More importantly, existing lifejackets are easily separated from people's bodies in water. Moreover, 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.
