The invention provides a multi-rotor unmanned aerial vehicle based on laser accurate falling line tour inspection. The multi-rotor unmanned aerial vehicle comprises a body. A suspension mechanism comprising a suspension rod, two driving wheels and two connecting plates is arranged on the upper portion of the body. The two parallel driving wheels each are internally provided with a motor driving system and externally provided with a concave ring. The two concave rings are simultaneously in sliding fit with a power transmission line through the motor driving systems, and a connected line of center points of the two concave rings is parallel to the power transmission line. The two connecting plates are opposite to the connected line of the center points and are fixed together with wheel axles of the two driving wheels, and a first camera and at least one laser radar are arranged on one side face of one of the two connecting plates towards the connected line of the center points. The suspension rod is fixed on one side face of the two connecting plates far away from the connected line of the center points, and the top end of the suspension rod is provided with at least one second camera. By utilizing the multi-rotor unmanned aerial vehicle, accurate line falling on the power transmission line t is achieved, the power consumption of the multi-rotor unmanned aerial vehicle is reduced, the duration time is prolonged, and the goal of long-time stable tour inspection is achieved.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle and electric power inspection, in particular to a multi-rotor unmanned aerial vehicle and an operation method based on laser light precise drop-off inspection. Background technique [0002] The icing, galloping, disconnection, and floating objects of overhead transmission lines often affect the safe operation of the power grid. Therefore, the automation and intelligent inspection of overhead transmission lines has increasingly become an important issue that needs to be solved urgently. [0003] In recent years, due to the miniaturization and light weight of sensors and the improvement of flight control systems, UAV technology has developed rapidly, providing new ideas and technical methods for power transmission line inspection operations. At present, multi-rotor UAVs are widely used in transmission line inspection operations due to their advantages of flexible maneuverability, ...
