Description

Technical Field

[0001] This utility model relates to the field of grounding equipment, specifically to a fast grounding and electric shock prevention structure for high-voltage power construction. Background Technology

[0002] High-voltage grounding wires are core safety devices in power systems used to connect electrical equipment to the earth, prevent electrostatic discharge and accidental electric shock, and are widely used in line and substation construction. Their main functions include establishing effective grounding protection, discharging residual charge, and ensuring the safety of workers.

[0003] Some clamping devices now use springs for clamping, but after long-term use, the springs are prone to fatigue deformation, resulting in rapid attenuation of clamping force and reduced reliability. Utility Model Content

[0015] The beneficial effects of this utility model are as follows: This utility model adopts a clamping method in which the threaded rod drives the double clamping arms to move synchronously in opposite directions, in conjunction with the limiting and guiding of the slider and the slide groove; the locking threaded rod plays the role of locking the threaded rod, preventing the safety hazards caused by the clamping arms moving to both sides; the orderly winding of the grounding wire is achieved by rotating the sleeve, crank handle, wire clamping plate and fixing clamp, preventing random tangling.

[0021] like Figure 1-4 As shown, a fast grounding and anti-electric shock structure for high-voltage power construction includes a clamp base 1. Two side plates 2 are fixed at both ends of the top of the clamp base 1. A threaded rod 3 is passed through the two side plates 2. Two opposing clamping arms 4 are threadedly connected to the threaded rod 3. Clamping grooves 5 are opened on the two opposing sides of the clamping arms 4. A grounding wire 6 is installed at the bottom of the clamp base 1.

[0022] Specifically, the grounding wire 6 needs to be grounded first. There is a certain gap between the two clamping arms 4. Then, it moves upward from the bottom of the high-voltage cable so that the high-voltage cable is located in the clamping groove 5. In this embodiment, the clamping groove 5 is set as a triangular structure to improve applicability. The threaded rod 3 is manually rotated to move the two clamping arms 4 relative to each other, thereby clamping the high-voltage line. The grounding wire 6 conducts the charge to the ground. The clamping arms 4 and the clamp base 1 need to be made of conductive materials. Operators need to wear insulated equipment when performing construction.

[0023] The bottom of the two clamping arms 4 is fixed with sliders 7, and the top of the wire clamp base 1 is provided with a groove 8 that cooperates with the sliders 7. Specifically, the sliders 7 and the groove 8 cooperate to play a limiting role. In this embodiment, the bottom of each clamping arm 4 is provided with two sliders, and both the sliders 7 and the clamping arms 4 are made of conductive material.

[0024] A connecting block 9 is provided at the bottom of the clamp base 1, and a conductive sheet 10 is installed on the side of the connecting block 9. The grounding wire 6 is connected to the tail of the conductive sheet 10. Specifically, the connecting block 9 and the conductive sheet 10 are connected by bolts and nuts. The connecting block 9 is made of conductive material and needs to transmit current.

[0025] A vertical plate 11 is fixedly connected to the bottom of the wire clamp base 1. A connecting rod 12 is fixed to the side of the vertical plate 11 near the connecting block 9. A rotating sleeve 13 is rotatably mounted on the connecting rod 12.

[0026] A baffle 14 is provided on the outside of the end of the rotating sleeve 13 away from the vertical plate 11. A crank handle 15 is fixed to the outside of the baffle 14. An insulating sleeve 16 is fitted on the outside of the crank handle 15. Specifically, only one baffle 14 is provided on the outside of the rotating sleeve 13 because the vertical plate 11 on that side can act as a blockage. Turning the crank handle 15 causes the rotating sleeve 13 to rotate, thereby retracting the grounding wire 6 onto the rotating sleeve 13. When the operator operates the crank handle 15, the insulating sleeve 16 provides protection.

[0027] One end of the threaded rod 3 extends to the outside of one of the side plates 2, and an operating rod 17 is radially fixed to the extension of the threaded rod 3; an insulating sleeve 16 is also fitted on the outside of the operating rod 17; specifically, the operating rod 17 makes it easier for the operator to rotate the threaded rod 3, and the insulating sleeve 16 provides protection.

[0028] A horizontally arranged wire clamping plate 18 is installed on the side of the vertical part of the connecting rod 12 and above the rotating sleeve 13; specifically, when the grounding wire 6 is wound on the rotating sleeve 13, the grounding wire 6 is located at the bottom of the wire clamping plate 18, which facilitates the winding of the grounding wire 6.

[0029] One of the side plates 2 has a locking threaded rod 19 installed on its top; specifically, the locking rod 19 is vertically threaded to the top of the side plate 2 near the operating rod 17. The threaded rod 3 is provided with a bearing rotatable connection to the side plate 2. Therefore, the locking rod 19 must avoid the position of the bearing and is located on the side of the bearing. The bearing adopts existing technology and is therefore not shown in the figure.

[0030] A fixing clip 20 for fixing the grounding wire 6 is provided on the side of the vertical plate 11 and above the rotating sleeve 13. The fixing clip 20 has a U-shaped structure and passes horizontally through the vertical plate 11 and is fixed by a nut. Specifically, the grounding wire 6 connected from the conductive sheet 11 is first fixed by the fixing clip, that is, one end of the grounding wire 6 is first limited, and then it is wound around the rotating sleeve 13 by the wire clamping plate 18 for easy operation. The fixing clip 20 is fixed by a nut and the tightness can be adjusted.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
