Description

[0002] At present, the country is vigorously developing clean energy such as wind, light, biomass, and nuclear power, and continuously increasing the proportion of renewable energy power generation installed capacity. With the rapid development of the energy industry, the fire safety issues in the production and use of power facilities have become a social focus. Taking new energy vehicles as an example, there are currently 16.2 million new energy vehicles in the province, and they are growing rapidly at a rate of 500,000 to 600,000 vehicles per year. At the same time, electric vehicle fire accidents occur frequently. In the first half of 2023, more than 100 electric vehicles were burned in fire accidents; traditional fire alarm means basically have a fire when the signal is detected, and it is impossible to achieve early warning before the accident. Compared with traditional fire alarm and early warning means, pyrolysis particle early warning technology detects fire earlier, thereby gaining more sufficient time for disposal, and can it effectively prevent fire accidents.

[0003] However, at present, the pyrolysis particle detection technology that can achieve extremely early warning is in its infancy in China, the relevant detection technology is still imperfect, and the detector products also have some problems, including: a single type of detection material, low detection sensitivity, maintenance requires consumables, high maintenance costs and low intelligence. In addition, in view of the difficulties faced by the application of pyrolysis particle detection technology in clean energy power sites, such as the feasibility of extremely early detection of lithium battery fires, detection of large space factories and warehouses, and detection of closed spaces, there is a lack of systematicity. In order to better ensure the early warning detection of new energy batteries, a fire warning detection device for new energy batteries is needed. Utility Model Content

On one side of the package body 1, a mounting seat 205 is provided inside one end of the input hose 202, and two rotating shafts 206 are provided inside the mounting seat 205. A rotating plate 207 is provided on the rotating shaft 206, and a return spring 208 is provided on one side of the rotating plate 207.
