Self-cleaning type engineering vehicle with automatic fire extinguishing function

Abstract

The invention discloses a self-cleaning type engineering vehicle with an automatic fire extinguishing function. The self-cleaning type engineering vehicle comprises an engineering vehicle body, a gasstorage tank arranged on the engineering vehicle body, a fire extinguishing agent tank and a blowout preventer, wherein the gas storage tank is provided with a first air outlet and a second air outlet, the first air outlet of the gas storage tank is connected with an air inlet of the blowout preventer, the second air outlet of the gas storage tank is connected with the air inlet of the fire extinguishing agent tank, and a discharge port of the fire extinguishing agent tank is connected with a feeding port of the blowout preventer. According to the self-cleaning type engineering vehicle with the automatic fire extinguishing function, when the engineering vehicle needs to be cleaned, compressed gas in the gas storage tank can enter the blowout preventer to blow the part needing to be cleaned, sundries on the engineering vehicle are blown off, so that cleaning work of the whole engineering vehicle is achieved, and a fire-proof part of the engineering vehicle can also be purged at regulartime to prevent combustible matters from being accumulated; and when a fire is ignited, fire extinguishing agents in the fire extinguishing agent tank can enter the blowout preventer for blowing underthe action of the compressed gas, and so that automatic fire extinguishing of the engineering vehicle can be realized.

Description

technical field [0001] The invention relates to an engineering vehicle, in particular to a self-cleaning engineering vehicle with an automatic fire extinguishing function. Background technique [0002] Engineering vehicles mainly use diesel or gasoline engines. During operation, fuel combustion generates a large amount of heat, which makes the entire engine body very hot, especially the outer surface of the air collecting pipe. The temperature even reaches above 600°C. When there are flammable substances in the workplace of engineering vehicles, the flammable light substances adhere to the engine and then fall on the gas collecting pipe. After being ignited by the high-temperature gas collecting pipe, it is likely to ignite the oily substances, thus causing spontaneous combustion of the vehicle; in addition, due to the aging of engineering vehicle cables, electric sparks may also cause spontaneous combustion of engineering vehicles. [0003] At present, the way for engineer...

Problems solved by technology

When a fire breaks out on a construction vehicle, since the engine is covered under the engine cover, the operator is not easy to detect the disaster at the initial stage of the fire, and it takes time for the driver and passengers to use the fire extinguisher to extinguish the fire, which often delays the best time to extinguish the fire, causing the fire to spread. Loss of property and personal safety

[0004] In addition, the cleaning of engineering vehicles is carried out to the maintenance point, and the compressed air at the maintenance point or manual cleaning is used. First, the cleaning is not timely, and the work must be stopped and cleaned at the maintenance point; second, the cleaning is time-consuming and laborious, and the cleaning is not thorough.
