Flight fire extinguishing device with dry powder and foam extinguishing agents

Abstract

The invention discloses a flight fire extinguishing device with dry powder and foam extinguishing agents. A fire fighting tank is fixed on an unmanned aerial vehicle body, a double-channel rotating shaft is inserted into the fire fighting tank, a large gear is fixed on the double-channel rotating shaft and meshed with a small gear, and the small gear is connected with a reduction motor; a high-pressure argon tank is arranged in the fire fighting tank and arranged on the double-channel rotating shaft in a sleeving manner, and a foam barrel and a dry powder barrel are arranged on the left side and the right side of the high-pressure argon tank respectively; the high-pressure argon tank is communicated with the foam barrel and the dry powder barrel through a foam gas inlet pipe and a dry powder gas inlet pipe respectively; a dry powder inlet, a foam inlet and two argon gas inlets are formed in the double-channel rotating shaft, the dry powder inlet and the foam inlet are communicated withan injection channel, and the argon gas inlets are communicated with a balance channel; the foam barrel is communicated with the foam inlet through a foam outlet pipe; the dry powder barrel is communicated with the dry powder inlet through a dry powder outlet pipe. The device has the beneficial effect of being capable of coping with fires of various fire sources.

Description

Technical field [0001] The present invention relates to the technical field of flying fire extinguishing devices, and more specifically, to a flying fire extinguishing device with two fire extinguishing agents: dry powder and foam. Background technique [0002] At present, there are great difficulties in extinguishing fires in some high-rise buildings. Existing fire-fighting equipment and fire-fighting facilities are difficult to reach to the height of high-rise buildings. There are serious defects in the fire-fighting of high-rise buildings. Therefore, fire-fighting drones should be used. Born. However, the existing fire-fighting drones can only carry one type of fire-extinguishing agent, and cannot cope with multiple fire sources. [0003] Therefore, in view of the above aspects, it is a problem for those skilled in the art to invent a flying fire extinguishing device with two fire extinguishing agents, dry powder and foam, which can deal with multiple fire sources. Summary of ...
