Problems solved by technology

However, due to its heavy structural weight and the large number of fire extinguishing bombs it carries, the UAV has a large take-off weight, fast power consumption, and short battery life, making it difficult to rise to higher floors to perform fire extinguishing tasks. Fire extinguishing on very high floors can also be used for forest fires where the fire range is too large for people to enter; and the layout of the UAV is that half of the propellers are located on the upper surface of the motor base, half of the propellers are located on the lower surface of the motor base, and the upper and lower surfaces of the motor base are located. The propellers are alternately arranged at intervals. Although this layout reduces the overall size of the UAV and avoids the collision of propeller tips, the aerodynamic interference between adjacent rotors increases due to the overlap of some propeller discs, making The aerodynamic efficiency is drastically reduced, which ultimately leads to a significant reduction in the flight time of the firefighting drone system

Abstract

The invention discloses a single-shot six-rotor-wing fire-extinguishing unmanned aerial vehicle. Folding pieces are mounted at all corners of a hexagon of a fuselage box body correspondingly, and oneends of vehicle arms are fixed to the fuselage box body through the folding pieces. A flight power system comprises six sets of flight power assemblies, and all the flight power assemblies are mountedat the cantilever ends of the vehicle arms correspondingly. A fire extinguishing bomb launcher is mounted in the middle of the lower surface of the fuselage box body. An aiming camera is located in front of the middle of the lower surface of the fuselage box body. The single-shot six-rotor-wing fire-extinguishing unmanned aerial vehicle combines the advantages of a multi-rotor unmanned aerial vehicle and a fire extinguishing bomb, the fire extinguishing height can reach a kilometer, and the single-shot six-rotor-wing fire-extinguishing unmanned aerial vehicle has the characteristics of smallsize and convenient transportation through the adopted folding vehicle arms; and through an adopted electromagnetic coil for boosting, the initial speed of the fire extinguishing bomb is high, the environment adaptability is good, and the shooting precision is high. The single-shot six-rotor-wing fire-extinguishing unmanned aerial vehicle can effectively solve the worldwide problem of high-rise building fire extinguishing.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle fire extinguishing, and in particular relates to a single-engine six-rotor fire-extinguishing unmanned aerial vehicle. Background technique [0002] With the rapid development of my country's industrialization and urbanization process, the number of high-rise buildings over 100 meters is increasing, and the subsequent high-rise building fires occur from time to time. Due to factors such as high floors, high density, road traffic and site restrictions, traditional fire-fighting equipment such as aerial ladder trucks, high-pressure water guns and ground fire monitors are difficult to effectively play a role in the face of high-rise building fires. Once a high-rise building fire occurs, it will cause casualties and huge economic losses. In view of the serious imbalance between existing fire-fighting equipment and high-rise building fires, it is urgent to develop a new type of fire-ex...
