Inflatable multifunctional life jacket for survival of victims

Abstract

The inflatable multifunctional life jacket comprises a life jacket body, a gas generation module, an oxygen supply breathing module, a positioning alarm module and a heat preservation module, the gas generation module comprises a plurality of reaction chambers and a gas supply pipe, and the reaction chambers are used for rapidly generating gas to inflate the life jacket body; the oxygen supply breathing module comprises an oxygen supply chamber, an oxygen supply pipe and an oxygen supply mask, the oxygen supply chamber generates oxygen for a person falling into water to inhale, a potassium superoxide cavity and an acetic acid aqueous solution cavity are formed in the oxygen supply chamber, and the oxygen supply pipe is communicated with the potassium superoxide cavity and the acetic acid aqueous solution cavity. A partition plate for communicating the potassium superoxide cavity with the acetic acid aqueous solution cavity is connected between the potassium superoxide cavity and the acetic acid aqueous solution cavity in a sliding manner and is connected with a pull rope; the positioning alarm module is fixed to the back of the life jacket body, a trigger switch is arranged on the positioning alarm module and connected with the pull rope, and a heat preservation layer is fixedly connected to the inner side of the life jacket body.

Description

technical field [0001] The invention relates to a sea survival equipment, in particular to an inflatable multifunctional sea survival life jacket. Background technique [0002] With the development of China's marine undertakings and the increasing number of water activities, at the same time, it is becoming more and more difficult for the navy to perform tasks. After aircraft and ships encounter danger on the ocean, the marine environment is complex and changeable and difficult to control. Survival of people on a ship or on a plane is very difficult. In the event of a marine accident, due to various problems such as poor mechanisms, scattered forces, and outdated equipment in marine rescue, it is difficult to search and rescue people in distress within 12 hours of the golden rescue time at sea under normal circumstances. Extending the life cycle of equipment will greatly improve the probability of being searched and rescued, so the research and improvement of life jackets i...

AI Technical Summary

Problems solved by technology

[0004] At present, life jackets on the market have single functions and low reliability, which cannot meet the needs of modernization, and life jackets are the guarantee for the survival of victims. Therefore, the requirements for the materials, specifications and functions of life jackets are particularly strict.
