Problems solved by technology

[0006] 1. Since the fire-fighting drone carries a fire-extinguishing device, its own weight increases, and the displacement of the drone needs to consume more power. When the fire-fighting drone is connected to a high-pressure water gun for fire extinguishing, it is necessary to realize spraying while extinguishing the fire. Displacement, relying solely on the rotor is very difficult. Displacement when spraying water will make the flight state of the multi-rotor UAV extremely unstable, wobbling and shaking, and in serious cases, there is a danger of crashing. The current displacement process, It is often to stop spraying water, and then spray water after adjusting the position, which not only takes a long time, but also delays the fire fighting time, the efficiency is not high, and the practicability is not strong;
[0007] 2. Existing UAVs are used for fire fighting, usually using multi-rotor UAVs, which do not require take-off and landing sites in cities, and are relatively flexible to use. However, when this UAV is disturbed by external forces, its own flight is stable In application, the high-pressure water gun is often connected with the shell of the fire-fighting drone. When the high-pressure water gun sprays, the jet recoil is relatively large, which is difficult to overcome only by the aircraft itself.

Abstract

The invention discloses a suspension fire extinguishing device applied to an unmanned aerial vehicle. The suspension fire extinguishing device comprises a mounting box, hydraulic assemblies, wind power assemblies and a control system, wherein a containing space is formed in the mounting box, the hydraulic assemblies and the wind power assemblies are symmetrically arranged on two sides of the mounting box, linkage of the hydraulic assemblies and the wind power assemblies is realized through transmission shafts, and the control system is used for controlling the rotating speed of the hydraulicassemblies; and by means of hydraulic turbines and fan impellers, part of recoil generated by water spraying of a high-pressure water gun is counteracted, then the flying stability of a multi-rotor-wing unmanned aerial vehicle in the spraying process is guaranteed, the flying safety of the unmanned aerial vehicle can be guaranteed, the purpose that the unmanned aerial vehicle accurately completesspraying fire extinguishing is also guaranteed, when the multi-rotor-wing unmanned aerial vehicle displaces, the pressure difference generated by the rotation of the fan impellers plays the role in assisting the displacement of the multi-rotor-wing unmanned aerial vehicle, so that the time for adjusting the spraying angle of the multi-rotor-wing unmanned aerial vehicle is saved, the fire extinguishing efficiency is improved, the rescue time is prolonged, and thus the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a hanging fire extinguishing device applied to a drone. Background technique [0002] With the popularization of science and technology, unmanned aerial vehicles have gradually entered everyone's field of vision. Among them, industrial-grade unmanned aerial vehicles have gradually been applied to various fields to play their own role, especially in high-risk areas focusing on firefighting. UAVs are used to replace some The importance of human action to the fire protection industry is self-evident; [0003] With the development of urbanization, there are more and more high-rise and super high-rise buildings. Once a fire occurs, the reaction speed and fire fighting are extremely difficult, especially for buildings above 30m. Fire-fighting devices have limited effects, and in many cases, the intervention of external fire-fighting equipment is required to control the...
