Vehicle engine housing fire extinguisher

Abstract

The invention discloses a vehicle engine housing fire extinguisher, which consists of a fire extinguishing switch, a safety plug, an air duct, an electromagnetic gas valve and a gas storage cylinder, wherein the fire extinguishing switch is arranged in a cab; the safety plug is arranged on the fire extinguishing switch; the fire extinguishing switch can be opened after the safety plug is unplugged; the electromagnetic gas valve is arranged between a cylinder opening of the gas storage cylinder and the air duct; a control power line of the electromagnetic gas valve is connected to the fire extinguishing switch; an air exhaust hole is formed in the air duct; the air duct is wound on a combustible part of the vehicle engine housing; and compressed liquid-state carbon dioxide is stored in the gas storage cylinder. After the fire extinguishing switch is opened, the electromagnetic gas valve is opened, the compressed liquid-state carbon dioxide stored in the gas storage cylinder is ejected out of the air exhaust hole on the air duct through the opening of the gas storage cylinder, and the vehicle engine housing is subjected to fire extinguishing and temperature reducing.

Description

technical field [0001] The utility model relates to a fire extinguisher for an engine compartment of a vehicle, especially a fire extinguisher which can be extinguished by turning on a fire extinguishing switch in a cab when a fire occurs in the engine compartment. Background technique [0002] There is no fire extinguisher that can be operated in the cab in the engine compartment of existing vehicles, and accidents of spontaneous combustion in the engine compartment caused by high temperature, long-term driving, collision accidents, and aging lines and oil circuits occur from time to time. The vehicle is completely burned down in a very short time, even endangering the life safety of the people in the vehicle. It is usually too late to extinguish the fire with existing fire extinguishers, and the vehicle has been burned and scrapped. Contents of the invention [0003] In order to overcome the deficiency that there is no fire extinguisher that can be controlled in the cab ...
