In the process of overhauling the high-voltage cable, the grounding device is very important equipment, and the grounding device can establish good electrical connection between the high-voltage cable and the ground, so that the equipment or the system can safely conduct out current during normal operation, and the damage of electric shock and other electrical faults when a worker approaches the high-voltage cable is avoided. In the conventional grounding device, the transmission mechanism 50 is not completely locked when being connected with the insulating rod 10, so that the transmission mechanism 50 is easy to accidentally separate from the insulating rod 10 when the hanging is not completed, and the transmission mechanism 50 is broken or even hurts the life safety of workers.

In order to solve the above-mentioned problems, referring to fig. 1 to 8, the present application provides a cable grounding device 100, wherein the cable grounding device 100 includes an insulation rod 10, a grounding wire 20, a clamping mechanism 30, a rotating mechanism 40, a transmission mechanism 50 and a locking mechanism 60. The clamping mechanism 30 is provided with an opening 31, and has a clamping state and a releasing state, and one end of the grounding wire 20 is connected to the clamping mechanism 30, so that the power-on cable 101 can be grounded through the grounding wire 20. The rotating mechanism 40 is connected to the clamping mechanism 30, and is used for driving the clamping mechanism 30 to rotate relative to the insulating rod 10 so as to change the orientation of the opening 31. One end of the transmission mechanism 50 is connected with the clamping mechanism 30, the other end is penetrated through the rotation mechanism 40 and is in rotation connection with the rotation mechanism 40, and the transmission mechanism 50 can respond to the rotation of the insulating rod 10 to move along the axis direction of the transmission mechanism 50 and change the size of the opening 31, so that the clamping mechanism 30 can be switched between a clamping state and a releasing state. In this way, the rotating mechanism 40 is combined with the connection and arrangement of the transmission mechanism 50, so that the orientation and the size of the opening 31 can be changed, and the cable grounding device 100 can be connected with cables in different directions, thereby improving the application scope of the application.

Wherein the locking sleeve 61 can be controlled to slide on the transmission mechanism 50 by the operating member 63, so that the locking member 62 locks or unlocks the transmission mechanism 50 and the insulating rod 10 and separates the transmission mechanism 50 from the locking sleeve 61. Thus, when the transmission mechanism 50 extends into the insulating rod 10, the locking piece 62 can lock the transmission mechanism 50 so that the transmission mechanism 50 and the insulating rod 10 cannot be separated from each other, and only when the operating piece controls the locking sleeve 61 to slide on the transmission mechanism 50, the transmission mechanism 50 and the insulating rod 10 can be separated from each other after the locking state between the transmission mechanism 50 and the insulating rod 10 is released, so that the transmission mechanism 50 is prevented from accidentally falling off from the insulating rod 10.

The ground wire 20 has a generally large cross-sectional area to reduce the resistance and ensure smooth current flow to ground.

Further, the ground wire 20 is also provided with a cable holder 21, one end of the cable holder 21 is fixed on the rotating mechanism 40, the clamping mechanism 30, and the like, and the other end clamps the ground wire 20, so that poor contact between the ground wire 20 and the clamping mechanism 30 due to shaking when the ground wire 20 is suspended is avoided.

That is, the first jaw 33 is fixed and the second jaw 34 is movable.

Further, the first clamping jaw 33 is formed with a bending portion facing the second clamping jaw 34, the second clamping jaw 34 is correspondingly formed with a groove 341, the groove 341 is used for allowing the clamping jaw of the first clamping jaw 33 to extend into, and the first clamping jaw 33 and the second clamping jaw 34 can be buckled, so that the electrified cable 101 can be clamped firmly.

In contrast, when the knob 433 is rotated in a direction approaching the rotation plate 431, the positioning portion 432 can be inserted into the engaging portion 44, thereby locking the angle between the first rotation seat 41 and the second rotation seat 42.

Next, the transmission mechanism 50 is mounted to the insulating rod 10, and the connection between the transmission mechanism 50 and the insulating rod 10 is locked by the locking mechanism 60. Further, the insulating rod 10 is lifted so that the clamping mechanism 30 approaches the power-on cable 101 until the power-on cable 101 enters the opening 31.

Then, rotating the insulating rod 10, transmitting power to the screw 532 through the universal coupling 54 and rotating the screw 532, pushes the second jaw 34 closer to the first jaw 33 to clamp the energized cable 101 within the opening.
