If the determination is no, step 4 is executed. Step 4: The UAV body 1 determines whether there is a snow removal instruction in the execution instruction. If the judgment is yes, the UAV body 1 drives the moving component 4 to be erected on the cable. At the same time, the blowing component 6 surrounds the cable, and the moving component 4 drives the UAV body 1 to move along the cable. The moving component 4 drives the second rotating plate 58 of the knocking component 5 to rotate. The second rotating plate 58 drives the rotating bearing 56 to rotate. The rotating bearing 56 intermittently contacts the first rotating plate 53. When the rotating bearing 56 contacts the first rotating plate 53, it pushes the first rotating plate 53 to rotate upward along the horizontal axis 54. When the rotating bearing 56 separates from the first rotating plate 53, the torsion spring 55 drives the first rotating plate 53 to rotate downward along the horizontal axis 54. The first rotating plate 53 swings up and down. The first rotating plate 53 drives the connecting cross bar 57 to swing up and down. The connecting cross bar 57 drives the second rotating plate 58 to swing up and down. The second rotating plate 58 drives the rubber sleeve 52 to knock and remove snow. At the same time, the blowing component 6 blows hot air to the outer wall of the cable. If the judgment is no, the UAV body 1 drives the camera 2 to perform normal inspection.
