Non-pressure storage type automatic fire extinguishing system and fire extinguishing method thereof

Abstract

The invention discloses a non-pressure storage type automatic fire extinguishing system. The non-pressure storage type automatic fire extinguishing system comprises a tank body, a piston, a reagent, a gas generator, a controller, a vehicle-mounted management system and a fire extinguishing pipeline. An upper end cover is mounted on an end portion of the tank body while a lower end cover is mounted on the other end portion; a piston is movably arranged in the tank body; a cover plate is mounted in the tank body between the piston and the lower end cover, and a through hole is formed in the plate body of the cover plate; the gas generator is mounted in a cavity between the cover plate and the lower end cover; the reagent is accommodated in the tank body between the piston and the upper end cover; the gas generator is connected to the controller; the controller is separately connected to an alarm and the vehicle-mounted management system; and one end of the fire extinguishing pipeline hermetically penetrates through the upper end cover and communicates with the inner part of the tank body. The invention also discloses a fire extinguishing method of the non-pressure storage type automatic fire extinguishing system. The non-pressure storage type automatic fire extinguishing system disclosed by the invention is good in sealing property, convenient to match and mount, free of an external gas source to push and safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of vehicle fire protection and relates to an automatic fire extinguishing system, in particular to a non-pressure storage type automatic fire extinguishing system and a fire extinguishing method thereof. Background technique [0002] With the rapid development of my country's new energy vehicle industry, vehicle fire safety is becoming more and more important. Especially for the fire protection system in the battery compartment of the bus, more and more bus companies have begun to pay attention to it. In the future, the "vehicle fire protection system" will become a standard product for new energy vehicles. At present, the traditional domestic fire extinguishing system mainly uses dry powder, aerosol and carbon dioxide as fire extinguishing agents. Due to its poor fire extinguishing effect, inability to prevent reburning, and pollution to the environment, it cannot meet the fire extinguishing work of new ene...

AI Technical Summary

Problems solved by technology

At present, the traditional domestic fire extinguishing system mainly uses dry powder, aerosol and carbon dioxide as fire extinguishing agents. Due to its poor fire extinguishing effect, inability to prevent reburning, and pollution to the environment, it cannot meet the fire extinguishing work of new energy vehicles; It is impossible to subcontract and control individual battery packs to extinguish fires; it is impossible to communicate with the on-board computer, and it is impossible to monitor in real time

However, new energy vehicles have problems such as small installation space, large number of battery packs and scattered distribution, high voltage of the vehicle system, and too many interference sources that may easily interfere with the control system.
