[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0019] 1. The utility model realizes the function of grounding multiple grounding wires simultaneously by setting a second ring, a moving rod, a moving block and a clamping plate. When the second ring rotates, two hinge blocks will rotate driven by the second ring. At this time, the two hinge blocks will drive two moving rods to move during the rotation.

Since the inside of the rotating ring is threadedly sleeved with the outer surface of the threaded column, when the rotating ring rotates, the threaded column will move downward along the inside of the fixed column driven by the rotating ring. At this time, the whole grounding cone will move downward driven by the threaded column, thus realizing the function of adjusting the length of the whole fixed column according to the height of the erected wire.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0029] like Figures 1 to 6 As shown, the utility model provides an electric grounding protection device, comprising:
[0030] A round block 1, a short groove 2 is formed on the top of the round block 1, and a first ring 3 is movably sleeved on the inner surface of the outer surface of the round block 1;
[0031] A clamping mechanism, which is arranged on the outer surface of the round block 1;
[0032] Among them, the clamping mechanism includes a second circular ring 4, the interior of the second circular ring 4 is movably connected to the outer surface of the circular block 1, the bottom end of the interior of the second circular ring 4 is fixedly connected to the outer surface of the first circular ring 3, the interior of the second circular ring 4 is fixedly installed with a hinge block 5, the interior of the hinge block 5 is hinged with a moving rod 6, the other end of the moving rod 6 is movably connected with a circular shaft 7, the bottom end of the circular shaft 7 is fixedly installed with a moving block 8, the outer surface of the moving block 8 is movably connected to the interior of the top end of the circular block 1, and the other end of the moving block 8 is fixedly installed with a moving plate 9. There are two moving plates 9, the outer surfaces of the two moving plates 9 are both movably connected to the interior of the top end of the circular block 1, and the facing ends of the two moving plates 9 are fixedly installed with a clamping plate 10.
[0033] When the second circular ring 4 rotates, the second circular ring 4 will drive the two moving rods 6 to move through the two hinge blocks 5, and then the other ends of the two moving rods 6 will drive the two moving blocks 8 to move through the two circular shafts 7. Due to the limiting effect inside the top of the circular block 1, the two moving blocks 8 will drive the two clamps 10 to move toward each other through the two moving plates 9. Due to the internal design of the two clamps 10, when the two clamps 10 move toward each other, the grounding wire located inside the top of the circular block 1 will be clamped and fixed.
[0034] Among them, a fixing block 11 is fixedly installed on the outer surface of the second ring 4, and a handle 12 is fixedly installed at the top of the fixing block 11.
[0035] Due to the design of the handle 12 and the fixing block 11, the operator can drive the second ring 4 to rotate through the handle 12 and the fixing block 11.
[0036] Among them, a square block 13 is fixedly installed at the top of the round block 1. An activity rod 14 is movably sleeved inside the square block 13. A pulling block 15 is fixedly installed on the front surface of the activity rod 14, and the back surface of the pulling block 15 is movably connected to the front surface of the square block 13.
[0037] Due to the design of the square block 13, the movement of the activity rod 14 will be limited, so that it can only move back and forth.
[0038] Among them, an activity block 16 is movably sleeved on the outer surface of the activity rod 14, and the bottom end of the outer surface of the activity block 16 is movably connected to the inside of the short groove 2.
[0039] When the activity rod 14 moves back and forth, at this time, the activity block 16 will drive along the inside of the short groove 2 under the drive of the activity rod 14.
[0040] Among them, a spring 17 is fixedly installed on the front surface of the activity block 16. The inside of the spring 17 is movably sleeved on the outer surface of the activity rod 14, and one end in front of the spring 17 is fixedly connected to the back surface of the square block 13.
[0041] When the activity block 16 moves forward, at this time, the spring 17 will be in a compressed state. Due to the elastic force of the spring 17, it will play a good role in resetting the overall movement of the activity rod 14.
[0042] Among them, the outer surface of the rear end of the activity rod 14 is movably connected to a toothed plate 18, and the outer surface of the toothed plate 18 is fixedly connected to the inside of the activity rod 14.
[0043] When the rear end of the activity rod 14 comes into contact with the outer surface of the toothed plate 18, it will play a good role in blocking the overall movement of the toothed plate 18.
[0044] Among them, a fixing column 19 is fixedly installed at the bottom end of the round block 1. An arc-shaped block 20 is fixedly installed at the bottom end of the outer surface of the fixing column 19. A rotating ring 21 is movably connected inside the arc-shaped block 20. The inside of the rotating ring 21 is movably sleeved on the outer surface of the fixing column 19. A rotating block 22 is fixedly installed on the outer surface of the rotating ring 21, and the outer surface of the rotating block 22 is movably connected to the inside of the arc-shaped block 20.
[0045] Due to the design of the four arc-shaped blocks 20, the rotating ring 21 can only rotate along its interior. Due to the design of the four rotating blocks 22, an operator can drive the rotating ring 21 to rotate through the rotating blocks 22.
[0046] Among them, a threaded column 23 is threadedly sleeved inside the rotating ring 21. The outer surface of the threaded column 23 is movably connected to the interior of the fixed column 19. The top end of the threaded column 23 is movably connected to the bottom end of the round block 1.
[0047] Due to the outer surface of the threaded column 23 being movably connected to the interior of the fixed column 19, the threaded column 23 can move up and down along the interior of the fixed column 19. Due to the outer surface of the threaded column 23 being threadedly sleeved inside the rotating ring 21, when the rotating ring 21 rotates, at this time the threaded column 23 will move downward under the drive of the rotating ring 21.
[0048] Among them, a stop block 24 is fixedly installed at the top end of the outer surface of the threaded column 23. The top end of the stop block 24 is movably connected to the bottom end of the round block 1.
[0049] When the threaded column 23 moves downward, at this time the four stop blocks 24 will move downward under the drive of the threaded column 23. When the bottom end of the stop block 24 contacts the top end of the rotating ring 21 during the downward movement, at this time the rotating ring 21 will block the downward movement of the stop block 24, thereby preventing the threaded column 23 from continuing to move downward.
[0050] Among them, a grounding cone 25 is fixedly installed at the bottom end of the threaded column 23. A vertical block 26 is fixedly installed on the outer surface of the grounding cone 25.
[0051] When the threaded column 23 moves downward, at this time the threaded column 23 will drive the entire grounding cone 25 to move downward. Due to the design of the four vertical blocks 26, the entire grounding cone 25 will not rotate after being buried in the soil, thereby increasing the stability after the grounding cone 25 is installed.
[0052] The working principle and usage process of the present utility model:
[0053] First, the operator drives the rotating ring 21 to move by rotating the rotating block 22. Due to the design of the four arc-shaped blocks 20, the rotating ring 21 can only rotate along its interior. At this time, the rotating block 22 will drive the rotating ring 21 to rotate. Since the outer surfaces of the threaded columns 23 are all movably sleeved inside the fixed columns 19, the threaded columns 23 can move up and down along the interiors of the fixed columns 19. Since the interior of the rotating ring 21 is threadedly sleeved with the outer surfaces of the threaded columns 23, at this time, the rotating ring 21 will drive the threaded columns 23 to move downward along the interiors of the fixed columns 19 during rotation. Immediately afterwards, the threaded columns 23 will drive the grounding cone 25 as a whole to move downward, thus realizing the function of adjusting the length of the fixed column 19 as a whole according to the height of the erected electric wire.
[0054] Subsequently, the operator places multiple ground wires inside the top of the round block 1. At this time, the operator makes the movable rod 14 move forward along the interior of the square block 13 by pulling the pull block 15. At this time, the movable rod 14 will release the blocking effect on the toothed plate 18 during backward movement. During this process, the movable rod 14 will squeeze the spring 17 through the movable block 16, making the spring 17 in a compressed state. Subsequently, the operator drives the fixed block 11 to move by the handle 12. Immediately afterwards, the fixed block 11 will drive the second ring 4 and the first ring 3 to move. Since the first ring 3 is movably sleeved inside the round block 1, at this time, the second ring 4 will rotate along the outer surface of the round block 1. At this time, the second ring 4 will drive the toothed plate 18 to rotate. At the same time, the two hinge blocks 5 will rotate under the drive of the second ring 4. Immediately afterwards, the two moving rods 6 will move under the drive of the two hinge blocks 5. At this time, the other ends of the two moving rods 6 will simultaneously squeeze and push the two round shafts 7 to make the two round shafts 7 move. Subsequently, the two round shafts 7 will drive the two moving blocks 8 to move. Since the outer surfaces of the two moving blocks 8 are movably connected to the interior of the top of the round block 1, the two moving blocks 8 can only move left and right. At this time, the two round shafts 7 will drive the two moving blocks 8 to move towards each other. Immediately afterwards, the two moving blocks 8 will drive the two clamping plates 10 to move towards each other through the two moving plates 9. Due to the design of the interiors of the two clamping plates 10, at this time, the ground wires located inside the top of the round block 1 will be clamped and fixed during the inward movement of the two clamping plates 10, thus realizing the function of being able to ground multiple ground wires simultaneously. Subsequently, the operator releases the pull block 15. At this time, the whole movable rod 14 will reset under the elastic force of the spring 17. When the rear end of the movable rod 14 comes into contact with the outer surface of the toothed plate 18, it will block the rotation of the second ring 4.
