Vehicle-mounted fire extinguishing system

Abstract

The invention relates to a vehicle-mounted fire extinguishing system. The vehicle-mounted fire extinguishing system comprises a heat detection device, a manual start button, a fire extinguishing device, a controller, an electric motor and a base, wherein the fire extinguishing device comprises a tank body and an executing mechanism, the heat detection device is electrically connected with the controller, the controller is electrically connected with the executing mechanism of the fire extinguishing device, the fire extinguishing device is fixed on the base, the base is rotationally arranged in an engine compartment by the electric motor, the executing mechanism of the fire extinguishing device comprises a solenoid valve which is arranged on a nozzle of a tank body, the controller drives the electric motor by an electric motor driving circuit, and the controller drives the solenoid valve by a solenoid valve driving circuit. The vehicle-mounted fire extinguishing system is low in cost and high in reliability, can be installed simply, the base is rotatable, multi-azimuth fire extinguishment can be realized, and when an automatic control system has a fault, a manual starting device can be adopted for realizing fire extinguishment.

Description

technical field [0001] The invention relates to a vehicle-mounted fire extinguishing system. Background technique [0002] Cars bring convenience to people’s lives, but also bring many safety hazards. According to the survey, there are at least hundreds of spontaneous combustion incidents of vehicles in the country every year. The main reasons for spontaneous combustion of vehicles are as follows: [0003] 1. Leakage. When the engine is working, the temperature of the ignition coil rises sharply, which is prone to high-voltage leakage, causing the temperature of the leakage to continue to rise, igniting the gasoline leaked from the engine, carburetor, etc., resulting in spontaneous combustion. [0004] 2. Oil leakage. Leaked gasoline is the most direct flammable substance, so the maintenance of the oil circuit is extremely important. [0005] 3. Electrical failure and short circuit. Some starter switches are welded due to the sintering of the contacts, and the starter sw...

AI Technical Summary

Problems solved by technology

When the engine is working, the temperature of the ignition coil rises sharply, which is prone to high-voltage leakage, causing the temperature of the leakage to continue to rise, igniting the gasoline leaked from the engine, carburetor, etc., resulting in spontaneous combustion

[0004] 2. Oil spill

[0005] 3. Electrical failure and short circuit

Some starter switches are welded due to the sintering of the contacts, and the starter switch cannot be released, causing the starter to start for a long time (the safe start time of the starter is 5S), causing the engine to heat up and catch fire

[0006] 4. The contact resistance is too large, the line contact is not solid, and the local resistance becomes larger to generate heat, which leads to fire of flammable materials

However, the fire will spread in an instant after the car spontaneously ignites, and the passengers cannot use fire extinguishers to extinguish the fire after being frightened. Therefore, the spare fire extinguishers for cars have not achieved the desired effect for many self-igniting cars.
