Projectile type high-altitude fire extinguishing unmanned aerial vehicle system and using method thereof

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to a projectile type high-altitude fire extinguishing unmanned aerial vehicle system. The projectile type high-altitude fire extinguishing unmanned aerial vehicle system comprises an unmanned aerial vehicle and an ammunition ejection mechanism mounted on the unmanned aerial vehicle. The ammunition ejection mechanism comprises an ammunition box, a launch canister, an ammunition loading tray, guiding gears, a transmission hinge and a driving motor. The ammunition box is installed on the upper portion of the launch canister and communicates with the launch canister, and the ammunition box is filled with a fire extinguishing bullet. The upper portion of the ammunition box is fixed to the bottom of the unmanned aerial vehicle, and the ammunition loading tray is disposed in the launch canister and slidably matched with the inner wall of the launch canister. The guiding gears are connected with the transmission hinge in a wrapped mode, and the bottom of the ammunition loading tray is connected with the transmission hinge through a connecting block. The driving motor is fixed to one side of the launch canister through a motor base, and the output end of the driving motor is connected with the transmission hinge through a driving wheel. By using a mode of accelerating projectile by the driving motor,the interference to the stability of an aircraft is reduced in the projectile process.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a projectile high-altitude fire-fighting unmanned aerial vehicle system and its use method. Background technique [0002] As the number and height of high-rise buildings in my country continue to rise, the pressure on fire rescue is increasing. With the existing fire extinguishing means, can not adapt to the demand of my country's urban high-rise building fire extinguishing. Affected by working principles and physical limitations, the special fire-fighting vehicle equipment used for external rescue of super high-rise buildings over 100 meters generally has the characteristics of large vehicle body, large deployment area, and complex supply and support equipment. Therefore, there is an urgent need for equipment that can quickly arrive in a short period of time, accurately judge, and timely fire and rescue equipment to implement fire extinguishing and solve the pr...

AI Technical Summary

Problems solved by technology

The existing means of fire extinguishing can no longer meet the needs of fire extinguishing for high-rise buildings in cities in my country.

Affected by working principles and physical limitations, the special fire-fighting vehicle equipment used for external rescue of super high-rise buildings over 100 meters generally has the characteristics of large vehicle body, large deployment area, and complex supply and support equipment. Therefore, there is an urgent need for equipment that can quickly arrive in a short period of time, accurately judge, and timely fire and rescue equipment to implement fire extinguishing and solve the problem of "inaccessible" large-scale rescue support equipment. The problem of "unable to unfold" and "out of reach"

[0003] The use of UAVs to carry out fire fighting and rescue operations in high-rise buildings has been a research topic in recent years. Although the technologies of fire extinguishing bombs and UAVs are relatively mature, there is still no good combination of the technical characteristics of fire extinguishing bombs and UAVs. Technical features are effectively combined to form practical high-tech products
