The top surface of the main base plate is provided with a fixing hole, and the fixing holes are respectively located on the left and right sides of the through hole, and the fixing holes are connected to the annular groove. A fixing bolt is sleeved inside the positioning hole, and the threaded end of the fixing bolt passes through the fixing hole and is connected to the internal thread of the thread groove. In the utility model, the fixing pile can be removed by rotating it 90°, which effectively saves the time of disassembly, is more convenient, and is effectively maintained.

Therefore, a substation grounding device is urgently needed to solve the above problems. Summary of the Invention

[0010] Preferably, a limiting groove is provided on the inner side wall of the sliding groove, the outer wall of the positioning rod is fixedly connected to a limiting block, and the limiting block is slidably connected to the inner side of the limiting groove.

[0011] Preferably, the rotating assembly includes a rotating block, which is fixedly connected to the top end of the positioning rod. The outer wall of the rotating block is rotatably connected to a rotating rack, and the top end of the rotating rack is fixedly connected to the bottom end of the push plate.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 , an embodiment provided by the utility model:

[0026] A substation grounding device includes a positioning sleeve 1, the bottom end of the positioning sleeve 1 is fixedly connected to a limiting sleeve 2, the top of the positioning sleeve 1 is movably connected to a cover plate 14, the bottom of the cover plate 14 is fixedly connected to a conductive rod 17, and the bottom end of the conductive rod 17 passes through the bottom of the positioning sleeve 1, and the inner side wall of the positioning sleeve 1 is fixedly connected to an insulating sleeve 13;

[0027] A slide groove 6 is provided on the outer walls of both sides of the positioning sleeve 1. The top of the slide groove 6 is set to be trapezoidal. A positioning rod 8 is slidably connected to the inner side of the slide groove 6. A rotating component is set at the top of the positioning rod 8. A push plate 11 is fixedly connected to the top of the rotating component.

[0028] When the substation grounding device is used, the positioning sleeve 1 is embedded in the ground, and the bottom end of the conductive rod 17 is passed through the bottom of the positioning sleeve 1. The bottom end of the conductive rod 17 is limited by the limiting sleeve 2, so that the conductive rod 17 can stably conduct electricity to the conductive wire 20. When the conductive rod 17 is in use, the positioning sleeve 1 protects the conductive rod 17, reduces the external erosion of the conductive rod 17 underground, thereby extending the service life of the conductive rod 17, and then the insulating sleeve 13 is used to isolate the conductive rod 17;

[0029] When the positioning sleeve 1 is embedded in the ground and contacts the ground, the push plate 11 and the positioning rod 8 are rotated through the rotating assembly, and the top of the slide groove 6 is set to a trapezoidal shape, which will cause the push plate 11 and the positioning rod 8 to become inclined. When the positioning sleeve 1 gradually moves downward, the pressure of the ground on the push plate 11 is converted into the downward pressure of the positioning rod 8 through the rotating assembly, causing the positioning rod 8 to move downward and embed into the ground at the bottom end of the positioning sleeve 1, thereby further improving the stability of the grounding device during use.

[0030] Furthermore, the bottom end of the positioning sleeve 1 is fixedly connected to the limiting sleeve 2, the bottom end diameter of the limiting sleeve 2 is larger than the top end diameter, the top outer wall of the positioning sleeve 1 is fixedly connected to the pressure plate 4, and the bottom of the pressure plate 4 is fixedly connected to the fixing rod 5.

[0031] When the positioning sleeve 1 is embedded in the ground, the pressure plate 4 can provide a force application position for the staff, and then the fixing rod 5 is embedded in the ground, thereby ensuring the stability of the top end of the positioning sleeve 1 during use.

[0032] Furthermore, a limiting groove 7 is provided on the inner side wall of the sliding groove 6 , and a limiting block 9 is fixedly connected to the outer wall of the positioning rod 8 , and the limiting block 9 is slidably connected to the inner side of the limiting groove 7 .

[0033] The limiting block 9 is slidably connected to the limiting groove 7 , thereby ensuring the stability of the positioning rod 8 sliding inside the limiting groove 7 .

[0034] Furthermore, the rotating assembly includes a rotating block 10 , which is fixedly connected to the top of the positioning rod 8 . The outer wall of the rotating block 10 is rotatably connected to a rotating frame 12 , and the top of the rotating frame 12 is fixedly connected to the bottom end of the push plate 11 .

[0035] The rotating frame 12 is rotatably connected to the rotating block 10 , so that the positioning rod 8 and the push plate 11 can rotate relative to each other.

[0036] Furthermore, the bottom of the cover plate 14 is fixedly connected to a connecting sleeve 16, and the connecting sleeve 16 is threadedly connected to the inner side of the top end of the positioning sleeve 1, the top end of the positioning sleeve 1 is fixedly connected to the fitting groove 3, and the bottom of the cover plate 14 is fixedly connected to a sealing sleeve 15, and the sealing sleeve 15 is fitted and connected to the inner side of the fitting groove 3.

[0037] The connecting sleeve 16 is threadedly connected to the inner side of the top end of the positioning sleeve 1 to ensure the stability of the connection between the cover plate 14 and the positioning sleeve 1, and then the sealing sleeve 15 is engaged and connected to the inner side of the engaging groove 3 to ensure the sealing of the connection between the cover plate 14 and the positioning sleeve 1.

[0038] Furthermore, the top of the cover plate 14 is fixedly connected to a wiring sleeve 18 , and the bottom of the wiring sleeve 18 is electrically connected to the top of the conductive rod 17 . The top of the wiring sleeve 18 is threadedly connected to a wiring head 19 , and the top of the wiring head 19 is electrically connected to a conductive wire 20 .

[0039] When the substation grounding device is in use, the conductive wire 20 is connected to the terminal head 19, and then the terminal head 19 is electrically connected to the terminal sleeve 18, so that the conductive wire 20 can be electrically connected to the conductive rod 17. After the conductive rod 17 is embedded in the ground, the conductive wire 20 can be grounded normally.

[0040] Furthermore, the bottom diameter of the limiting sleeve 2 is larger than the top diameter, and the top of the sliding groove 6 is set to be trapezoidal.

[0041] Working principle: When the substation grounding device is in use, the conductive wire 20 is connected to the terminal head 19, and then the terminal head 19 is electrically connected to the terminal sleeve 18, so that the conductive wire 20 can be electrically connected to the conductive rod 17, and the positioning sleeve 1 is embedded in the ground, and the bottom end of the conductive rod 17 is limited by the limit sleeve 2, so that the conductive rod 17 can stably conduct electricity to the conductive wire 20. When the positioning sleeve 1 is embedded in the ground and contacts the ground, the push plate 11 and the positioning rod 8 are rotated by the rotating component, and the top of the slide groove 6 is set to a trapezoid, which will cause the push plate 11 and the positioning rod 8 to become inclined. When the positioning sleeve 1 gradually moves downward, the pressure of the ground on the push plate 11 is converted into the downward pressure of the positioning rod 8 through the rotating component, so that the positioning rod 8 moves down and is embedded in the bottom end of the positioning sleeve 1 underground, thereby further improving the stability of the grounding device during use.
