[0022] In the present invention, the AGV trolley 1 is provided with a tool storage cabinet 3 and a warning alarm system. The tool storage cabinet 3 is used to store tools such as tools, safety fences, fence poles, signboards, grounding wires, etc. The warning alarm system can be installed on the AGV trolley 1, which includes an ultrasonic sensor device 20 and a voice alarm device 21. The ultrasonic sensor device 20 and the voice alarm device 21 are both electrically connected to the main control board 14, and the second battery 9 supplies power to the ultrasonic sensor device 20 and the voice alarm device 21. When the maintenance vehicle is performing the encapsulation grounding wire operation, the warning alarm system is automatically turned on; when a moving object approaches the AGV trolley 1, the ultrasonic sensor device 20 senses the information of the movement of the object and feeds back the corresponding electrical signal to the main control board 14, so that the voice alarm device 21 sends a voice alarm signal.

[0023] In the present invention, the rotating device 6 includes a mounting seat 601, a servo motor 602 and a rotating shaft 605; the mounting seat 601 is fixed to the micro-adjustment device 5, and two parallel side panels 603 are arranged on its side; both ends of the rotating shaft 605 are rotatably fixed to the side panels 603, and one end of the rotating shaft 605 is fixed to the grounding wire insulating rod 7; the servo motor 602 is used to drive the rotating shaft 605 to rotate and is fixed to the mounting seat 601, and is electrically connected to the first battery 17 built into the AGV trolley 1 and the PLC controller 19, that is, the servo motor 602 is powered by the first battery 17 built into the AGV trolley 1, and the servo motor 602 is controlled to rotate by the PLC controller 19, so that the grounding wire insulating rod 7 can rotate between a horizontal position and a vertical position.

The AGV trolley 1 can identify the location information through the QR code or RFID and run to the designated location according to the predetermined route. After the AGV trolley 1 moves to the designated location, the rotating device 6 rotates the grounding wire insulating rod 7 to a vertical position (in order to reduce the occupied space, the grounding wire insulating rod is placed horizontally in the initial state), and then the lifting device 2 lifts the various components fixed above it, and then the micro-adjustment device 5 fine-tunes the height of the grounding wire intelligent clamp 8. Before encapsulating the grounding wire, the electrical contact 4 detects the power supply of the line again to effectively prevent safety accidents. After the distance sensor 16 detects that the AGV trolley 1 is in place, the background server sends a command to control the tightening machine 11 to start, so that the movable clamp 12 moves in the direction of the fixed clamp 13 to clamp the grounding wire.

[0026] The present invention provides an automated operation mode for power grid operation and maintenance scenarios, which realizes the automation of transporting tools to the construction site, detecting whether the line is energized, and installing and removing the grounding wire, which is beneficial to improving operation efficiency, reducing the labor intensity of staff, and reducing the probability of safety accidents. The present invention is applicable to a variety of operation scenarios, and is flexible and convenient to operate, and can be used for mobile operations.
