[0002] Grounding wires are used in line and substation construction to prevent electrostatic induction from nearby charged objects, which may cause electric shock or accidental closing of the switch. Grounding wire devices are also called integrated grounding devices. Grounding wire devices are important components to ensure the safe operation of power systems and electrical equipment.

[0003] Chinese patent CN115000774A discloses a multifunctional wiring tool, which has a crank slider mechanism composed of an insulating rod, an upper clamp body, a lower clamp body and a connecting rod; when the insulating rod is placed vertically, the upper clamp body slides downward along the insulating rod under the action of its own weight, so that the jaws of the lower clamp body open downward; when the jaws of the upper clamp body are hooked on the wire, the operator releases the insulating rod, and the insulating rod pulls the connecting rod under the action of its own weight, so that the jaws of the lower clamp body close upward, clamping the wire between the jaws of the upper clamp body and the lower clamp body. This wiring tool can automatically open the jaws when hooking the wire, and after hooking the wire, it can automatically close the jaws by relying on the deadweight of the insulating rod to achieve clamping and grounding connection of the wire. The success rate of connecting the wiring tool to the wire is extremely high, and the connection and disassembly operations are very simple. In addition, this wiring tool can also be used to break the ice layer on the surface of the wire, which has the advantages of simple operation and high deicing efficiency.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual Figure 1-5When hanging, hold the insulating rod 1, and guide the stop rod 9 and the special-shaped rod 8 to quickly fit the cable and the special-shaped rod 8. At this time, the outer wall of the cable contacts the arc surface of the tongue-shaped rod 10. Move the insulating rod 1 to slide the arc surface of the tongue-shaped rod 10 and the outer wall of the cable, so that the tongue-shaped rod 10 slides downward in the movable groove 11. The tongue-shaped rod 10 compresses the spring 12. At the same time, the tongue-shaped rod 10 drives the movable block 20 to move downward without contacting the plug 13. The cable finally passes through the tongue-shaped rod 10. At this time, the cable and the tongue-shaped rod 10 are separated. Under the action of the spring 12, the spring 12 restores the tongue-shaped rod 10. The cable is in the restored position, at this time, it is between the clamping block 5, the connecting rod 6, the arc block 7 and the tongue-shaped rod 10, and then the turntable (not marked in the figure) is rotated, and the turntable drives the operating rod 3 to rotate in the insulating rod 1, and the operating rod 3 makes the upper end of the screw rod 2 rotate in the clamping block 5, and the screw rod 2 rotates to make the connecting rod 6 slide downward on the clamping block 5 and the stop rod 9, and the connecting rod 6 drives the arc block 7 to move down to the clamping block 5 to clamp and fix the cable, and at the same time, the arc block 7 drives the special-shaped rod 8 to move down, and the special-shaped rod 8 presses down the tongue-shaped rod 10, and the tongue-shaped rod 10 compresses the spring 12, and the tongue-shaped rod 10 drives the movable block 20. When the inclined surface of the movable block 20 contacts the inclined surface of the plug rod 13, the movable block 20 continues to move downward to make the plug rod 13 slide forward on the stop rod 9, and the plug rod 13 drives the connecting block 14 to slide in the placement groove 15. At the same time, the connecting block 14 compresses the spring 2 16. When the plug rod 13 completely enters the stop rod 9, the movable block 20 moves downward, and the rear wall of the plug rod 13 slides on the front wall of the movable block 20. When the tongue-shaped rod 10 is completely squeezed into the movable groove 11, the plug rod 13 corresponds to the slot 17. Under the elastic force between the springs 16, the spring 16 drives the plug rod 13 to return to its original position through the connecting block 14. The grounding wire device is inserted into the slot 17 to complete the suspension of the grounding wire device; when the grounding wire device is removed, the turntable is rotated in the opposite direction to restore the arc block 7 to its original position, and the grounding wire device is removed; when the device needs to be used again, the pull block 4 needs to be pulled forward, and the pull block 4 drives the insertion rod 13 to disengage from the slot 17. At this time, under the elastic force between the springs 1 and 12, the tongue-shaped rod 10 is restored to its original position and can be used; the problem that the wire clamp opening of the grounding wire is small and the C-shaped opening makes it difficult for the wire clamp to clamp the wire when it is suspended is solved, the need to increase the deadweight of the insulating rod 1 to improve the clamping and fixing effect is avoided, and the burden brought by the insulating rod 1 is reduced.
