Description

technical field [0001] The invention relates to a fire extinguishing system, in particular to a bus fire extinguishing system, which belongs to the field of automobiles. Background technique [0002] Existing buses are mainly closed buses with air conditioners, and the windows are all closed and cannot be opened through conventional operations. The fire extinguishing system on the existing buses is a hand-held fire extinguisher, which is installed on the inside of the bus. In some positions, when a fire breaks out in the car, the fire is manually extinguished. The problem brought about by this is that in the event of a fire, the escape exits in the car are only the front and rear doors or the roof escape openings that some buses are equipped with, and the windows need to be broken, and the passenger density in the car is very high. Large, that is to say, only passengers close to the door or the escape exit can escape from the car at the first time, and passengers in the mid...

AI Technical Summary

Problems solved by technology

The existing fire extinguishing devices in the car are far from enough in terms of quantity, efficiency and ease of access, especially when a fire breaks out in the car, the passengers are extremely nervous, and the passengers closest to the fire extinguisher may not be able to find it in time The fire extinguisher should be lifted and operated in time to extinguish the fire, and the passenger closest to the fire point may not necessarily obtain the fire extinguisher in his vicinity in time. Therefore, a rapid and efficient fire extinguishing system is required
