Problems solved by technology

Its advantages are: easy to use and good life-saving effect, etc., but due to the use of high-pressure gas cylinders as the gas source, there are the following disadvantages: (1) The inflation speed is greatly affected by the ambient temperature. The expansion of the gas absorbs heat, so the phenomenon of "freezing" occurs at the exhaust port, blocking the exhaust port, failing to achieve the purpose of lifesaving, and the temperature is lower than -20°C and cannot be used; (2) Explosion occurs when encountering high temperature or severe impact (3) The structure of the gas source device is rela

Embodiment Construction

[0010] exist figure 1 Among them, life jacket (1), belt with gas generator (2), low-temperature pyrotechnic gas generator (3), starting device (4), one-way valve (5), inflatable hose (6), and many inside the life jacket Two interconnected airbags (7) form a quick inflatable, warm-keeping type water life-saving device. After the person in distress falls into the water, he can manually start the starting device (4) fixed on the belt (2) to ignite the low-temperature pyrotechnic gas generator (3) and generate gas. The gas generated by the gas generating agent passes through the one-way valve ( 5), the inflatable hose (6) enters the lifejacket (1), and the thermal insulation air bag (7) in the lifejacket will be quickly filled with a mixed gas of nitrogen and carbon dioxide at a temperature of about 50° C. in a few seconds, so that the person in distress can surface. Rescue at sea takes a long time, especially in autumn and winter when the cold sea water will make people lose con...

Abstract

This invention provides quick air charging thermal insulating water live-saving equipment and comprises life jacket (or air bag) and low temperature pyrotechnic gas generator with electric igniter, which is characterized in that the device can negate temperature adjustable gas to keep temperature in live-saving equipment on 40~50Deg and compensate gas for live-saving equipment decreased for temperature fall to prolong life time of person in ice-cold sea and enhance help possibility. It is fit to use in river, lake and sea under all weather conditions particular to cold autumn and winter.

Description

Technical field [0001] The invention relates to a fast-inflating, warm-keeping water life-saving device. In particular, it is a marine lifesaving device that automatically inflates air after a person falls into the water, and keeps the gas temperature in the lifejacket at 25-35°C for a long time to keep the human body warm. technical background [0002] Existing water life-saving device mainly divides three classes, and a class is the buoy ring, lifejacket etc. that kapok or foam etc. are done, can float a period of time in water. But the disadvantage is that it is usually bulky and inconvenient to carry and store. The second type is a self-inflating water lifesaving device, and its gas source is usually composed of a high-pressure cylinder filled with carbon dioxide or air and a more complicated mechanism for controlling the inflation operation. Its advantages are: easy to use and good life-saving effect, etc., but due to the use of high-pressure gas cylinders as the gas ...
