Automatic fire extinguishment device of vehicle engine cabin

Abstract

The invention discloses an automatic fire extinguishment device of a vehicle engine cabin. The device is provided with a fire extinguisher container arranged in an engine cabin, wherein an electronic valve is arranged at an outlet of the fire extinguisher container and is communicated with a plurality of multi-nozzle hoses in the engine cabin through pipelines; a control circuit board is arranged in the engine cabin, is connected with the electronic valve through a control circuit and is also connected with a smoke sensor; a cab alarm controller is arranged in a cab; an alarm lamp, a loudspeaker and a fire extinguishment control button are arranged on the cab alarm controller. According to the device, the spontaneous combustion phenomenon can be discovered in first time after the spontaneous combustion of the vehicle engine cabin occurs, judgment caution information is obtained, and the vehicle-mounted fire extinguishment device is started, so that the spontaneous combustion probability of a vehicle can be reduced, the property loss caused by the spontaneous combustion of the vehicle can be reduced, and the casualty accidents of drivers and passengers caused by untimely discovery of the spontaneous combustion of the vehicle can be reduced.
