Preferably, the number of the stopper 262 is three. A through hole 41 is provided on the third support 304. When the jet cleaning assembly 2 is in the first state (i.e., the movable seat 321 of the jet pipe assembly 32 is adjacent to the second support 303), the stopper 262 is supported in the through hole 41. When the jet cleaning assembly 2 is in the second state (i.e., the movable seat 321 of the jet pipe assembly 32 is adjacent to the third support 304), the conduit 324 is supported in the through hole 41. Preferably, a chamfer 411 is provided on the side of the through hole 41 away from the second support 303. The stopper 262 includes a first portion 621 and a second portion 622.

At this time, the stopper 262 and the enclosure 327 protect the first jet head 254 of the first jetting member 325 to prevent the airflow of the drone 1 from affecting the ejected liquid of the first jet head 254, thereby ensuring the jetting route and accuracy.

Under the cooperation of the gear 315 and the rack 221, the sliding seat 30 can move relative to the mounting seat 22. At the same time, the worm 312 drives the screw 316 to rotate, and the rotation of the screw 316 drives the moving seat 321 of the injection pipe assembly 32 to move from the second support The seat 303 moves toward the third support 304; during this process, the second injection member 326 rotates outward relative to the first injection member 325 under the action of the elastic member 264, and the enclosure 327 is opened as the second injection member 326 rotates; when the movable seat 321 moves to the third support 304, the operator controls the water pump through the remote control device to pump the liquid in the liquid storage tank 21 to the injection assembly 23, and opens the corresponding valves to allow the liquid to be ejected from the first injection head 254 and the second injection head 612 to spray and clean the insulator to be cleaned. After cleaning is completed, the operator controls the motor 311 to reverse through the remote control device, and the screw 316 drives the movable seat 321 of the injection tube assembly 32 to move from the third support 304 to the second support 303. The second injection member 326 rotates inward relative to the first injection member 325 under the action of the second part 622 and the chamfer 411 of the through hole 41, and the first part 621 and the enclosure 327 are retracted in the through hole 41, which facilitates the movement of the drone 1 and enables the drone 1 to easily and flexibly pass through complex scenes.
