Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle delivery, in particular to a unmanned aerial vehicle lifting and separation device. Background Art

[0002] Drone transportation systems are widely used in various scenarios. Drones can deliver materials to designated locations quickly and safely through airdrops, greatly improving logistics efficiency. At the same time, drones are also seen as a future trend in short-distance delivery within cities. In the military and civilian fields, drone destruction missions are extremely risky and complex tasks. At present, drones are mostly used to lift and drop objects above the area to be destroyed for destruction tasks. However, during the destruction process, traditional delivery methods mainly rely on drones to directly control the cutting of ropes or use manual operations. These methods have certain limitations and shortcomings when dealing with such high-risk destruction tasks.

[0003] For example, CN220905322U discloses a drone delivery device, including a top plate, a delivery box fixedly connected to the bottom of the top plate, two symmetrically distributed opening and closing plates hinged at the bottom of the delivery box, the two opening and closing plates are in contact with each other, the top plate is provided with a micro motor, the output shaft of the micro motor is rotatably connected to the top plate, a bidirectional screw is fixedly connected to the output shaft, and the bidirectional screw is rotatably connected to the top plate. When working: the micro motor drives the bidirectional screw to rotate, the bidirectional screw causes the two moving walls to move back to back, and the top rod on the moving arm gradually separates from the inclined block at the bottom of the opening and closing plate, so that the delivered object pushes the opening and closing plate open under its own weight for delivery. Using the weight of the delivered object to push the opening and closing plate open may not be able to be delivered accurately and quickly when the weight of the delivered object is not large enough or the shape is not suitable.
