Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle traction equipment, in particular to a winch traction device for a multi-rotor unmanned aerial vehicle. Background Art

[0002] Drones are widely used in forest prevention and control, field inspections and many other aspects. When a multi-rotor drone uses a rope to drop items, it is necessary to control the rope up and down through a winding mechanism. During this process, attention should be paid to control. If the rope is retracted, there is a possibility of interfering with the propeller. Once the rope is entangled with the propeller, the drone will crash. Therefore, the rope needs to be effectively controlled and the items are fixed on the hook. However, due to the influence of the external environment, the items are easy to fall off the hook, which affects the stability of the equipment during use and brings inconvenience. To this end, we propose a winch traction device for a multi-rotor drone. Utility Model Content
