The foreign object cleaning mechanism is disposed at the bottom of the mounting mechanism, and the unmanned aerial vehicle flight mechanism is disposed at the top of the mounting mechanism. The foreign object cleaning mechanism includes a mounting seat, and rotating seats are symmetrically arranged at the bottom of the mounting seat. A grasping claw is movably connected inside the rotating seat. A number of tooth openings are evenly distributed inside the grasping claw. A side support frame is fixedly installed on the outside of the grasping claw. An electric telescopic rod is arranged at one end of the side support frame. The output end of the electric telescopic rod is connected to a connecting member. Cutting blades are movably installed at both ends of the connecting member.
