Fixed fire extinguishing system for public bus

Abstract

The invention relates to the field of fire extinguishing of public transport vehicles and discloses a fixed fire extinguishing system for a public bus. The fixed fire extinguishing system comprises a gas propulsion tank, a fire extinguishing tank, a gas release device, a control module and a fire extinguishing delivery system, wherein the gas release device is arranged at the gas outlet end of the gas propulsion tank; the gas outlet end of the gas release device is connected with the input end of the fire extinguishing tank through a gas delivery line; the output end of the fire extinguishing tank is connected with the fire extinguishing delivery system; the fixed fire extinguishing system further comprises a heat-sensitive linear detection line and a power supply module; the power supply module, the gas release device and the heat-sensitive linear detection line are respectively connected with the control module. According to the fixed fire extinguishing system disclosed by the invention, the heat-sensitive linear detection line is used for detecting the temperature; during firing at high temperature, the heat-sensitive linear detection line is triggered, the fire extinguishing delivery system sprays fire extinguishing liquid, and the fire extinguishing operation in the first time can be realized; in addition, the fixed fire extinguishing system is equipped with an alarming horn and an alarming lamp; during driving, a driver can clearly see the alarming lamp and thereby is prompted.

Description

technical field [0001] The invention relates to the field of public transport vehicle fire extinguishing, in particular to a public bus fire extinguishing system. Background technique [0002] With the rapid development of urban economy and the continuous expansion of city scale, the number of public transport vehicles has increased dramatically. Buses are densely populated and closed spaces, and the public security situation is relatively complicated. Arson and spontaneous combustion incidents occur frequently, seriously threatening the lives of drivers and passengers, and seriously disturbing social stability and unity. [0003] At present, buses are equipped with portable dry powder fire extinguishers. The fire extinguishers are generally placed far away from the driver, and the bus is crowded with people. After a fire, it is in an extremely chaotic state, and the fire extinguishers cannot be effective in a timely manner. And bus catches fire, because the space is airtig...

AI Technical Summary

Problems solved by technology

Buses are densely populated and closed spaces, and the public security situation is relatively complicated. Arson and spontaneous combustion incidents occur frequently, which seriously threaten the lives of drivers and passengers and seriously interfere with social stability and unity.

[0003] At present, buses are equipped with portable dry powder fire extinguishers. The fire extinguishers are generally placed far away from the driver, and the bus is crowded with people. After a fire, they are in a state of extreme confusion. The fire extinguishers cannot play their role in a timely and effective manner.

When a bus catches fire, due to the airtight space, passengers have almost no time to escape and save themselves, which is prone to serious casualties

[0004] In addition, superfine dry powder fire extinguishing devices have been used in public bus engine compartments, new energy bus power battery compartments, and new energy bus motor electronic control compartments, which cannot achieve continuous spraying of fire extinguishing agents in terms of dosage or efficiency, effectively suppressing fires Effect
