Automatic early warning fire extinguishing method for preventing vehicle from spontaneously combusting

Abstract

The invention provides an automatic early warning fire extinguishing method for preventing a vehicle from spontaneously combusting. The inside of an engine case is provided with a central processing unit, a temperature sensor, a gas sensitive sensor, a laser probe, a photoelectric smoke sensor, a direct current over-current protector, a power relay, an oil circuit switch and a fire extinguisher. The central processing unit is connected with the temperature sensor, the gas sensitive sensor, the laser probe, the photoelectric smoke sensor, the direct current over-current protector, the power relay, the oil circuit switch and the fire extinguisher through a data wire to form a detection early warning fire extinguishing system; the outside of an oil supply pipeline which is connected with an engine is covered with a transparent plastic pipe; an oil absorption discoloration flame retardant material is filled between the oil supply pipeline and the transparent plastic pie to form an oil supply pipeline protection structure; and a brake oil tank and an engine oil tank which are arranged at the periphery of the engine are isolated through a flame retardant plate. The automatic early warning fire extinguishing method has the advantages that: the design is scientific and rational; the method gives priority to preventing the pipeline from oil leakage and short circuit, and is supplemented by the passive fire extinguishing; and even though the spontaneous combustion is caused by the fire of the circuit after the oil leaks, the central processing unit can cut off the power relay and the oil circuit switch as soon as possible, so the loss of the spontaneous combustion is minimized.

Description

technical field [0001] The invention relates to a method and device for preventing spontaneous combustion of vehicles, in particular to an automatic early warning fire extinguishing method for preventing spontaneous combustion of vehicles. Background technique [0002] Regardless of whether it is a car or a train, spontaneous combustion may occur during the driving process. The spontaneous combustion of the vehicle will not only cause property damage to the owner, but also endanger the lives of the owner or passengers, and also affect the normal traffic order. Regarding the prevention of vehicle There are many patent documents on spontaneous combustion, but most of them are to solve the problems after spontaneous combustion, such as how to detect, how to extinguish the fire, etc., and do not fundamentally prevent the generation of spontaneous combustion, so the root cause cannot be cured. Contents of the invention [0003] The purpose of the present invention is to provide...
