Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-6 As shown, the utility model provides a high-voltage cabinet grounding device, including a base 1, a placement plate 2 is provided on one side of the base 1, a plurality of evenly distributed first clamping plates 21 are fixedly installed on the side of the placement plate 2 away from the base 1, a second clamping plate 22 used in conjunction with each first clamping plate 21 is provided on the side of the placement plate 2 away from the base 1, and two symmetrically distributed first connecting blocks 23 are fixedly installed on the side of each second clamping plate 22 away from the corresponding first clamping plate 21, the first connecting blocks 23 are located at the edge of the second clamping plate 22, and a threaded column 24 is threadedly connected to the middle part of each first connecting block 23, and the threaded column 24 is fixed near the side of the placement plate 2. A connecting column 25 is installed, and a fixing groove 26 used in conjunction with the connecting column 25 is opened on the side of the placement plate 2 close to the second clamping plate 22. A rotating wheel 27 is fixedly installed on the side of the threaded column 24 away from the connecting column 25. A plurality of annular and evenly distributed anti-skid strips 28 are fixedly installed on the outside of the rotating wheel 27. By providing the anti-skid strips 28, the friction between the hand and the rotating wheel 27 is increased, which makes it easier to rotate the rotating wheel 27 and drive the threaded column 24 to rotate. A handle 6 is fixedly installed on the side of each second clamping plate 22 close to the first connecting block 23. By providing the handle 6, it is easier to move the second clamping plate 22 and clamp or loosen the grounding wire.

[0020] Two groups of symmetrically distributed trapezoidal grooves 3 are provided on one side of the base 1 close to the placement plate 2. Trapezoidal blocks 31 are provided on the internal sliding cards of the trapezoidal grooves 3. The trapezoidal blocks 31 are fixed at the edge of the placement plate 2. Two groups of symmetrically distributed square grooves 32 are provided on one side of the base 1 close to the trapezoidal grooves 3. Each square groove 32 is located on one side of the trapezoidal groove 3. By providing the square grooves 32, the installation of the trapezoidal blocks 31 is facilitated, so that the trapezoidal blocks 31 can be moved into the trapezoidal grooves 3, thereby installing the placement plate 2, which is convenient for later disassembly and replacement.

[0021] A plurality of evenly distributed slide grooves 4 are provided on one side of the placement plate 2 close to the second clamping plate 22. A card block 41 is provided inside the slide groove 4 for sliding movement. The card block 41 is fixed on the corresponding second clamping plate 22. By providing the card block 41 and the slide groove 4, the second clamping plate 22 is more stable when moving.

[0022] A limiting block 5 is fixedly installed on one side of each trapezoidal block 31, and a limiting groove 51 used in conjunction with the limiting block 5 is opened on the side of the base 1 close to the square groove 32. The limiting groove 51 is located on the other side of the trapezoidal groove 3. By setting the limiting block 5 and the limiting groove 51, the placement plate 2 is fixed on the base 1 and is more stable.

[0023] Each of the first clamping plate 21 and the second clamping plate 22 is provided with an arc groove 7 on its inner side, which makes it easier to clamp the ground wire and prevents the ground wire from moving outwards when clamping the ground wire, thereby affecting the clamping of the ground wire.

[0024] Two symmetrically distributed second connecting blocks 8 are fixedly installed at the two side edges of the base 1, and a bolt hole 81 is opened through the middle of each second connecting block 8. By setting the bolt hole 81, it is convenient to install the base 1 into the inside of the high-voltage cabinet by bolts.

[0026] Then, when installing the grounding wire of the high-voltage cabinet, one side of the grounding wire is fitted with the inner side of the first clamping plate 21, and then the second clamping plate 22 is manually moved toward the direction of the first clamping plate 21, so that the inner side of the second clamping plate 22 is fitted with the other side of the grounding wire, and then the rotating wheel 27 is rotated to drive the threaded column 24 to rotate, and the threaded column 24 is connected to the thread of the first connecting block 23, driving the connecting column 25 to slowly move toward the fixing groove 26, so that the connecting column 25 is stuck in the corresponding fixing groove 26, thereby clamping the grounding wire, so that the grounding wire is installed on the placement plate 2, and then other grounding wires are installed respectively.
