Description

Unmanned aerial vehicle high altitude rescue nacelle Technical Field The invention relates to the technical field of unmanned aerial vehicle pods, in particular to an unmanned aerial vehicle high-altitude rescue pod. Background The fire disaster of the super high-rise building has the core characteristics of high spreading speed, obvious chimney effect and easy blocking of inner stairs and elevators by high-temperature toxic smoke, and when the fire disaster progresses to the bombing stage, trapped people cannot escape through an inner passage of the building, the establishment of a life passage from the outside of the building becomes the only feasible rescue scheme. In recent years, industrial heavy-duty unmanned aerial vehicles are gradually introduced into the field of fire-fighting high-altitude rescue by virtue of the advantages of strong maneuverability, no limitation of ground traffic and terrain and capability of reaching hundred meters high altitude, but the technical defects and potential safety hazards which cannot be overcome in the prior art scheme are particularly divided into two types: The first type is an air-drop material type rescue unmanned aerial vehicle, such as the Chinese patent with publication number CN114379781B, which is used for air-drop rescue materials such as rescue bags to trapped positions. However, in a real fire scene, trapped people are often in extremely panic, overdrawn or injured states, and only materials are acquired, so that the trapped people cannot be separated from a high-temperature combustion area, and further, the space transfer of the people cannot be realized, and only a temporary protection effect can be achieved, so that substantial rescue cannot be completed. The second type is a direct-hanging rescue unmanned aerial vehicle, such as the chinese patent with publication No. CN114228999B, which attempts to directly bind the unmanned aerial vehicle with the human body for rope lowering by driving a rope-collecting mechanism with a motor inside the unmanned aerial vehicle. The method directly applies huge dynamic load to the fragile frame and the miniature gearbox of the unmanned aerial vehicle, has extremely high risk of mechanical fatigue and fracture, and simultaneously has the pendulum effect generated by high-altitude wind gust, wind shear and personnel suspension, so that the unmanned aerial vehicle is extremely easy to cause out-of-control attitude and fatigue fracture of mechanical structure, and finally causes catastrophic accidents that the unmanned aerial vehicle and trapped personnel crash together, and does not meet the safety redundancy standard of high-altitude lifesaving. Disclosure of Invention Based on the above, it is necessary to provide an unmanned aerial vehicle high-altitude rescue nacelle. In order to achieve the purpose, the invention provides the unmanned aerial vehicle high-altitude rescue nacelle which comprises an aerial operation assembly and a ground fixing assembly which are mutually independent, wherein the aerial operation assembly and the ground fixing assembly form a load transmission link only through a rescue rope, no physical connection is formed in the whole process, and complete decoupling of the unmanned aerial vehicle and personnel loads is achieved from the root. The aerial operation assembly comprises a nacelle main body, and a cableway building mechanism, a safety belt retracting mechanism, a safety belt throwing mechanism and a clamping release mechanism which are arranged on the nacelle main body, wherein the upper end of the nacelle main body is provided with a connecting structure which is matched with an external unmanned aerial vehicle body, and the aerial operation assembly can be matched with an industrial heavy-duty unmanned aerial vehicle with the main stream load of more than 20kg in the market, so that quick disassembly and rigid fixation are realized. The ground fixing assembly comprises a ground fixing frame, two fixing winding and unwinding devices, a rescue rope and a safety lifting hook, wherein the ground fixing assembly is kept in a physical separation state with the aerial operation assembly in the processes of taking off, air transportation and full rescue of an unmanned aerial vehicle, and the ground fixing frame is rigidly fixed at a ground rescue end and is used for providing stable ground support and power input for a rescue cableway. The cableway building mechanism comprises an encircling locking mechanism and a wire guide wheel, the cableway building mechanism is detachably connected with the nacelle main body through the clamping and releasing mechanism and used for encircling and anchoring with a high-altitude anchor to form a high-altitude fulcrum of a rescue cableway, two ends of the rescue rope are respectively connected with the two fixed winding and unwinding devices, the rescue rope winds the wire guide wheel to form the rescue cableway, and the safety lifting hook is fixed on
