[0002] In order to ensure the patrol of the power system, it is necessary to conduct round-the-clock inspections of high-voltage lines, towers and related circuit equipment; power inspection drones are efficient, safe and flexible as a whole, and are widely used in the inspection operations of power systems.

[0003] For example, Chinese patent CN116632717B discloses a drone inspection device and inspection method for power inspection. The device provides lift for the inspection body through a multi-rotor and accurately completes the inspection operation through a camera.

[0004] However, there are usually only high-voltage wires between the towers, and the distance between the towers is relatively long.

[0033] In this embodiment, when the adjustable power system 2, the suspension mechanism 3 and the cleaning module 4 work normally, when inspecting near the tower of the high-voltage line, the driving motor 235 drives the blades 234 to rotate, thereby providing lift, and drives the drone body 1 to fly by rotating the mounting block 231 and the rotating arm 22; the conditions of the tower, the high-voltage line and the power equipment on the tower are recorded by the smart camera 14 on the drone body 1, and judged by the controller 12; if an abnormal condition is found, the corresponding equipment information is remotely sent to the remote control terminal through the controller 12; When moving between towers, it is only necessary to observe the status of the high-voltage line; therefore, the controller 12 controls the driving motor 235 and the blades 234 to make the drone body 1 fly to the vicinity of the high-voltage line, at which time the high-voltage line is located on the side of the first stop wheel 321; the drone body 1 is controlled to continue to approach the high-voltage line until the high-voltage line pushes the L-shaped rotating frame 322 to rotate through the first stop wheel 321, so that the high-voltage line is located directly below the rotating roller 318; at this time, the lift provided by the driving motor 235 and the blades 234 is reduced, so that the drone body 1 gradually moves downward The first stopper 321 of the high-voltage wire pushes the L-shaped rotating frame 322 to rotate, so that the second stopper 323 rotates to the lower side of the high-voltage wire to block the high-voltage wire, until the high-voltage wire is completely stuck in the middle of the rotating roller 318; during this process, the fixed sleeve 41, the sliding sleeve 42, the vibration spring 43 and the conforming scraper 44 on the support frame 315 move until the conforming scraper 44 is stuck on the high-voltage wire; The controller 12 controls the electric push rod 233 to drive the rotating mounting block 231 to rotate, adjusts the posture of the blade 234 on the rotating mounting block 231, and makes the driving force of the blade 234 along the high-voltage line direction; drives the blade 234 to rotate through the driving motor 235, thereby providing power to move along the high-voltage line; rotates the roller 318 to roll with the high-voltage line; thereby drives the drone body 1 to move along the high-voltage line through the slider 316, the slide groove 317, the support frame 315, the fixing frame 311 and the fixing rod 312; During this process, the floating spring 314 and the fixing rod 312 cooperate to allow the fixing frame 311 to move a certain amount relative to the drone body 1, thereby ensuring stability during the movement; At the same time, the conformal scraper 44 slides in contact with the high-voltage line; the dust on the high-voltage line is cleaned by the conformal scraper 44; if there are solid objects such as bird droppings on the high-voltage line; the solid objects block the conformal scraper 44; the conformal scraper 44 drives the sliding sleeve 42 to move relative to the fixed sleeve 41; the vibration spring 43 stretches; until the pulling force of the vibration spring 43 is sufficient to drive the sliding sleeve 42 and the conformal scraper 44 to remove the solid obstruction.
