[0002] Transmission and distribution lines refer to lines used to transmit electricity. Transmission lines use transformers to step up the voltage of the electric energy generated by the generator, and then connect it to the transmission line through control equipment such as circuit breakers. Transmission lines are divided into overhead transmission lines and cable lines. As we all know, grounding refers to the connection of the center point of the power system and electrical equipment, the exposed conductive parts of the electrical equipment, and the conductive parts outside the device to the earth by conductors.

Then, one end of the grounding wire 11 is connected to the grounding column 12, thereby completing the grounding operation of the wires of the power transmission and distribution line.

[0022] As an optional technical solution of the utility model, the movable joint structure 2 includes an extension rod 201, an adjustment socket 202, a terminal head 203 and an adjustment bolt 204. The extension rod 201 is slidably connected to the inside of the support rod 1. A plurality of adjustment sockets 202 are provided on one side of the extension rod 201. The top of the extension rod 201 is fixedly installed with a terminal head 203 connected to the grounding wire 11. The outer surface of the support rod 1 is threadedly connected with an adjusting bolt 204. Before using the grounding device, the extension rod 201 is first extended from the inside of the support rod 1 to an appropriate length according to the height of the user and the height of the wire, so as to adjust the terminal head 203 to an appropriate height, and connect the adjusting bolt 204 to the adjustment socket 202 at an appropriate position, thereby fixing the extension rod 201 so that the extension rod 201 no longer moves. At this time, the terminal head 203 can be connected to the wires of the power transmission and distribution line.

[0023] As an optional technical solution of the present invention, the outer surface of the grounding column 12 is fixedly connected to a fixed base plate 13, and a plurality of fixed anchors 14 are inserted into one side of the fixed base plate 13.

[0028] 1) According to the height of the user and the height of the wire, the extension rod 201 is extended from the inside of the support rod 1 to a suitable length, so as to adjust the wiring head 203 to a suitable height, and the adjustment bolt 204 is connected to the adjustment socket 202 at a suitable position, so as to fix the extension rod 201;

[0029] 2) Adjust the terminal head 203 to a suitable height according to the height of the power transmission and distribution line wires, and make the movable plate 6 drive the clamping plate 7 to move towards the direction close to the support rod 1, at which time the clamping spring 5 is in a compressed state;

[0030] 3) Pass one end of the grounding wire 11 through the inside of the plurality of wire loops 8, and slowly loosen the movable plate 6, so that the clamping plate 7 and the outer surface of the grounding wire 11 are closely attached to each other under the reaction force of the clamping spring 5, thereby clamping the grounding wire 11. If the grounding wire 11 is still relatively long at this time, wind the grounding wire 11 around the winding roller 11 and wind the grounding wire 11 of a suitable length;

[0031] 4) Connect one end of the grounding wire 11 to the grounding post 12 and connect the terminal 203 to the wire of the power transmission and distribution line, thereby performing a grounding operation on the wire of the power transmission and distribution line.
