Description

Special folding life raft of fire control Technical Field The invention relates to the technical field of fire-fighting life rafts, in particular to a special folding life raft for fire fighting. Background The special life raft for fire protection is high-performance emergency rescue equipment designed for disaster sites such as fire disaster, flood and the like, is mainly used for rapidly transferring trapped personnel, crossing obstacles or providing a temporary risk avoidance platform, and is more emphasized in fire resistance, rapid deployment and multi-environment adaptation capability compared with the common life raft. In order to facilitate folding and storage, the existing fire-fighting life rafts on the market usually exhaust the gas in the life raft, when the fire-fighting life raft is used, a high-pressure gas cylinder is used, after a valve is opened, liquid carbon dioxide in the high-pressure gas cylinder is instantaneously vaporized and expanded to fill the air raft, and firefighters rescue by using the life raft. When rescue is carried out on emergency rescue sites such as fire disaster, flood and the like, a plurality of life rafts are required to be deployed, so that the high-pressure gas cylinders are required to inflate the plurality of life rafts, the gas outlet flow of the high-pressure gas cylinders is limited, only 1-2 life rafts can be inflated simultaneously, the simultaneous inflation of the plurality of life rafts cannot be realized, the subsequent life rafts are required to be queued for waiting, the gold rescue time of emergency rescue is extremely short, trapped people cannot be timely rescued and rescue force cannot be quickly unfolded due to the inflation waiting, and the emergency rescue device is inconvenient to use. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the special folding life raft for fire fighting, which has the advantage that a single life raft can be inflated by self, so that queuing inflation is not needed, the rescue force is quickly unfolded, the rescue efficiency of workers in gold rescue time is greatly improved, and trapped people can be rescued in time.
