Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a UAV hoisting device. Background Art

[0002] UAV, short for unmanned aerial vehicle, is an unmanned aircraft controlled by a radio remote control and computer program, or operated completely or intermittently autonomously by an onboard computer. Power construction projects often take place in difficult, mountainous areas, uninhabited areas, and other harsh environments with steep terrain and limited access. During the construction and maintenance of power infrastructure, components need to be transported to power line towers or mountaintops. Mechanized lifting equipment is difficult to access, and conventional human and animal transport is difficult to achieve. Therefore, using remote-controlled drones to transport and lift power components has become a time-saving, labor-saving, and convenient option.

[0003] Chinese patent CN220616171U discloses a hoisting mechanism for a gasoline-powered drone, comprising a hoisting net bag with lifting rings at each corner, each of which is fixedly connected to the hoisting net bag via a connecting rope. A corresponding hook is provided at each corner of the hoisting net bag, connected to the lifting ring via a lifting rope, and a rope-collecting mechanism is installed below the hook to adjust the lifting rope. Although the patent achieves height adjustment of the hoisting mechanism through the rope-collecting device, the hoisting mechanism in this patent is suspended at the bottom of the drone via a soft rope. In mountainous areas where power construction is carried out, with strong winds, the hoisting mechanism will sway with the wind when the drone is in flight during the hoisting construction process, causing the hoisting mechanism's center of gravity to be unstable, directly affecting the drone's flight stability and safety. In extreme conditions, the hoisting mechanism's center of gravity changes too quickly, even causing the drone to crash due to sudden weightlessness, resulting in direct economic losses.

[0004] From the above, it can be seen that there is an urgent need to provide a UAV lifting device with a simple structure, stable flight, and adjustable lifting height. Utility Model Content
