Abstract

A safeguard with alarm function for high-pressure H2 container is composed of anti-impact unit at both end of said high-pressure H2 container, a safety valve able to be automatically opened when H2 pressure is too high, a high-safety fuse able to be fused when ambient temp is too high (fire accident for example) for releasing H2, and a pressure sensor for detecting the leakage of H2.

Description

technical field [0001] The invention relates to an alarm device for inflammable and explosive gas safety guarantee, in particular to a hydrogen safety guarantee alarm device. Background technique [0002] Hydrogen energy is regarded as a main development direction of new energy in the future because of its cleanness, recyclability, and inexhaustibility, and it is mainly used in the automotive field. It is planned to produce more than 1 million vehicles by 2012; except for the price, the driving performance of hydrogen-powered vehicles is already the same as that of ordinary vehicles, and the development potential is huge. The safe storage and transportation of hydrogen is one of the core technologies of hydrogen-powered vehicles. At present, there are mainly hydrogen storage methods such as low temperature, adsorption, high pressure, and carbon nanotubes. Among them, high-pressure hydrogen storage is characterized by its directness, simplicity, convenience, low cost, and eas...
