Fire-fighting system for passenger compartment of bus

Abstract

The invention discloses a fire-fighting system for a passenger compartment of a bus. The fire-fighting system comprises a bus-mounted power supply, a system control unit, a nitrogen propellant tank, a constant-pressure water-based extinguishing agent storage tank body, a fire extinguishing agent conveying pipeline, a spraying nozzle and a system start switch, wherein the bus-mounted power supply serves as a system power supply and supplies power to the overall system; the system control unit controls a valve of the nitrogen propellant tank; the nitrogen propellant tank is filled with a nitrogen propellant; the constant-pressure water-based extinguishing agent storage tank body stores a water-based extinguishing agent at a constant pressure; the system start switch controls the start and the stop of the system control unit. Compared with fire-fighting equipment of the existing bus, the fire-fighting system has the following benefits: the novel water-based extinguishing agent can extinguish fire effectively and is harmless to human health; the water-based extinguishing agent is stored at the normal temperature, so that the extinguishing agent is convenient to maintain and refill; the potential safety hazard is avoided when compared with that adopting pressure-containing storage.

Description

Technical field

[0001] The patent of the present invention relates to an automobile fire-fighting system, in particular to a fire-fighting system for a passenger compartment of a bus. Background technique

[0002] At present, there is no mature fire-fighting system for the passenger cabin of large buses on the market. The fire-fighting facilities on the existing large buses are vehicle-mounted handheld fire extinguishers, mainly including dry powder type and foam type. These two types of fire extinguishers are high-pressure tanks. There are certain potential safety hazards, such as leakage, which may easily cause panic among passengers. In the face of sudden vehicle fires, due to the complex driving environment of vehicles, hand-held fire extinguishers often cannot play the role of fire protection, which can be seen from the vehicle fire accidents that occur from time to time in China.
