Excavator, hood of engine compartment and fire extinguishing device in engine compartment of excavator

Abstract

The invention discloses a fire extinguishing device in an engine compartment. The fire extinguishing device comprises a fire extinguisher, a hose and a first hard pipe, wherein one end of the hose communicates with the fire extinguisher, and the other end of the hose communicates with the tail end of the first hard pipe; and a plurality of air outlets are formed in the first hard pipe and the topend of the first hard pipe is closed. During using, opening of the fire extinguisher is only needed, dry powders can be transported through the hose and the first hard pipe into the engine compartmentfor fire extinguishing, opening of a hood is not required, so that fire extinguishing in the engine compartment is achieved in the premise of non opening of the hood. The invention further provides the hood of the engine compartment and an excavator adopting the fire extinguishing device in the engine compartment.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing devices, in particular to an excavator, an engine room cover and an engine room fire extinguishing device. Background technique [0002] In the engine room of the excavator, combustibles such as oil stains will be produced during the maintenance and lubrication process, aging lines, and combustibles attached to the turbocharger may burn. If the fire cannot be extinguished in time and effectively, a fire accident will easily occur. After a fire breaks out in the engine room, the firefighters cannot extinguish the fire at the root of the fire without opening the engine hood. If the engine hood is opened, more oxygen will rush into the combustion environment and deflagration will occur, which will easily lead to injuries of the firefighters and the expansion of the fire. [0003] Therefore, how to provide a fire extinguishing device in the engine room to realize fire extinguishing in the ...

If the fire cannot be extinguished in time and effectively, it is very easy to cause a fire accident

After a fire breaks out in the engine room, if the firefighters do not open the engine hood, they will not be able to extinguish the fire at the root of the fire. If the engine hood is opened, more oxygen will rush into the combustion environment and deflagration will occur, which will easily cause injuries to the firefighters and the expansion of the fire.
