Problems solved by technology

[0002] Due to the limited lifting height of existing fire trucks, there is no effective way to extinguish high-rise fires. Therefore, many manufacturers are thinking of launching fire extinguishing bombs from the ground or drones to extinguish the fire, but because the launcher has requirements for the weight of the fire extinguishing bombs , so the dry powder limit of the warhead belt is limited, and the warhead does not necessarily explode around the fire point when it enters the house. At the same time, the shrapnel produced by the explosion of the warhead can easily cause harm to personnel.

Abstract

A powder drive type fire extinguishing cannon comprises a powder containing box, a cannon pipe and a main pressure source; the main pressure source pressurizes a cannon pipe from the cannon tail of the cannon pipe, the powder containing box is fixed to the peripheral face of the cannon pipe, the powder containing box comprises an auxiliary pressurizing pipe, a box body, a flow control plate and a steering engine, the auxiliary pressurizing pipe is communicated with the top of the box body, the box body is communicated with the cannon pipe, the connecting position of the box body and the cannon pipe is a flow combining fork, the flow control plate partitions a channel for communicating the box body with the cannon pipe, and the steering engine controls the flow control plate. Powder fire extinguishing agents can be continuously sprayed out, and the beneficial effects of being small in recoil and small in weight are achieved.

Description

technical field [0001] The invention relates to the field of fire extinguishing guns, in particular to a powder driving type fire extinguishing gun. Background technique [0002] Due to the limited lifting height of existing fire trucks, there is no effective way to extinguish high-rise fires. Therefore, many manufacturers are thinking of launching fire extinguishing bombs from the ground or drones to extinguish the fire, but because the launcher has requirements for the weight of the fire extinguishing bombs , so the dry powder limit of the warhead belt is limited, and the warhead does not necessarily explode around the fire point when it enters the house. At the same time, the shrapnel produced by the explosion of the warhead is extremely easy to cause injury to personnel. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention proposes a powder-displacing fire extinguishing cannon, which realizes the continuous spraying of t...
