Description

Technical Field

[0001] This utility model belongs to the technical field of grounding devices for power engineering, and in particular relates to a grounding rod that can be quickly locked. Background Technology

[0002] Cable grounding rods are an indispensable safety protection device in power system maintenance operations. Their main function is to establish a temporary grounding path on de-energized cables or equipment. By connecting the de-energized equipment with conductor end clamps and the grounding device with grounding end clamps, a low-impedance discharge circuit is formed. Its core functions include: forcibly short-circuiting the equipment to the grounding grid to prevent personnel from being electrocuted due to accidental restoration of power; discharging induced voltage generated by nearby live lines and residual charge on equipment; and providing an equipotential protection environment for maintenance personnel. It is a mandatory safety measure in accordance with the "Electric Power Safety Work Regulations".

[0003] Existing grounding rods still have some problems during use, such as: the clamp locking relies on manually turning the bolts or adjusting the screw rod, which is difficult to operate at high altitudes, in confined spaces or in bad weather, and there is a lack of a quick locking confirmation mechanism, requiring additional checks on the clamping status. To address these issues, we provide a grounding rod that can be quickly locked. Utility Model Content

[0004] The purpose of this invention is to provide a grounding rod that can be quickly locked. By cooperating with the adjustment mechanism and the fixing mechanism, it solves the problem in the existing grounding rods that rely on manually turning the bolts or adjusting the screw rods to lock the wire clamps, lack a quick locking confirmation mechanism, and require additional checks on the clamping status.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a grounding rod that can be quickly locked, comprising a clamp, an insulating operating plate fixedly connected to the bottom of the clamp, a connecting rod disposed inside the insulating operating plate, and an adjusting mechanism disposed inside the insulating operating plate. The adjusting mechanism includes an adjusting toothed plate fixedly connected to the bottom of the connecting rod, a fixing box fixedly connected to one side of the insulating operating plate, a spring fixedly connected to the fixing box, and a fixing toothed plate fixedly connected to one side of the spring. The fixing box contains a fixing mechanism, which includes a fixing block fixedly connected to one side of the fixing toothed plate, a push plate fixedly connected to the other side of the fixing block, an anti-detachment plate fixedly connected to one side of the push plate, an anti-detachment insert disposed inside the anti-detachment plate, and a fixing rod disposed inside the fixing box.

[0007] The present invention is further configured such that a push rod is fixedly connected to the bottom front side of the adjusting tooth plate, and a push groove adapted to the push rod is provided on the front side of the insulating operating plate.

[0008] The present invention is further configured such that a vertical plate is fixedly connected to the inner wall of the insulating operating plate, and a limiting vertical groove is provided on one side of the adjusting tooth plate, wherein both the vertical plate and the limiting vertical groove are convex in shape.

[0009] The present invention is further configured such that there are four springs, which are respectively arranged at the four corners inside the fixed box, and the insulating operating plate is provided with a through groove adapted to the fixed toothed plate on the side adjacent to the fixed box.

[0010] The present invention is further configured such that a limiting telescopic rod is fixedly connected inside the fixed box, and the other end of the limiting telescopic rod is fixedly connected to the fixed toothed plate.

[0011] The present invention is further configured such that both the fixed box and the fixed block are provided with fixed through holes adapted to the fixed rod, and the front side of the fixed box is provided with a movable through groove adapted to the push plate.

[0012] The present invention is further configured such that the anti-detachment plug is fixedly connected to the fixing rod, and the anti-detachment plate has an anti-detachment groove inside that is adapted to the anti-detachment plug.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model uses a push rod to drive the adjusting tooth plate to move vertically, which drives the wire clamp to clamp the conductor. At the same time, the push plate pushes the fixed tooth plate to mesh with the adjusting tooth plate to form a toothed self-locking mechanism. This process simplifies the traditional bolt tightening to a pushing action, realizing the wire clamp "one push to lock", which significantly shortens the operation time. The tooth plate meshing structure provides continuous clamping force, avoids repeated manual adjustments, and improves the reliability of clamping.

[0015] 2. The fixing mechanism of this utility model aligns the fixing through hole by pushing the push plate, inserts the fixing rod through the fixing block and the fixing box, and rotates the fixing rod to make the anti-detachment plug lock into the anti-detachment groove to form a physical hard lock. This design establishes a secondary interlocking barrier and effectively eliminates the risk of accidental loosening of traditional grounding rods.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figures 1-5This utility model is a grounding rod that can be quickly locked, including a clamp 1, an insulating operating plate 2 fixedly connected to the bottom of the clamp 1, a connecting rod 3 inside the insulating operating plate 2, an adjusting mechanism 4 inside the insulating operating plate 2, the adjusting mechanism 4 including an adjusting toothed plate 401 fixedly connected to the bottom of the connecting rod 3, a fixing box 402 fixedly connected to one side of the insulating operating plate 2, a spring 403 fixedly connected to the inside of the fixing box 402, and a fixing toothed plate 404 fixedly connected to one side of the spring 403. A fixing mechanism 5 is provided inside the fixing box 402, the fixing mechanism 5 including a fixing block 501 fixedly connected to one side of the fixing toothed plate 404, a push plate 502 fixedly connected to the other side of the fixing block 501, an anti-detachment plate 503 fixedly connected to one side of the push plate 502, an anti-detachment insert 504 disposed inside the anti-detachment plate 503, and a fixing rod 505 disposed inside the fixing box 402.

[0027] Specifically, by adjusting the mechanism 4, the wire clamp 1 can be quickly opened and closed and initially locked. The operator places the wire clamp 1 in the designated position, then pushes the push rod 6 to clamp the conductor with the wire clamp 1. Then, the push plate 502 is pushed, which moves the fixed tooth plate 404 towards the adjusting tooth plate 401. At the same time, the fixed tooth plate 404 and the adjusting tooth plate 401 are engaged, and the spring 403 is stretched. The fixing mechanism 5 provides a secondary mechanical interlock. After the fixed tooth plate 404 and the adjusting tooth plate 401 are engaged, the fixing rod 505 is inserted into the fixing through hole 10 to fix the fixing block 501 and the fixing tooth plate 404. The fixing rod 505 is rotated so that the anti-detachment plug 504 on the fixing rod 505 is inserted into the anti-detachment groove 11. At this time, the push plate 502 and the fixing rod 505 are fixed to prevent the fixing rod 505 from accidentally slipping off during use. Specific Implementation Example 2

[0029] Please see Figures 1-5 Based on the first specific embodiment, a push rod 6 is fixedly connected to the bottom front side of the adjusting tooth plate 401. A push groove adapted to the push rod 6 is opened on the front side of the insulating operating plate 2. A vertical plate 7 is fixedly connected to the inner wall of the insulating operating plate 2. A limiting vertical groove 8 is opened on one side of the adjusting tooth plate 401. Both the vertical plate 7 and the limiting vertical groove 8 are convex. There are four springs 403, which are respectively set at the four corners inside the fixed box 402. The side of the insulating operating plate 2 adjacent to the fixed box 402 is provided with a groove that matches the fixed tooth plate 401. The four-phase compatible connecting slots are provided. The fixed box 402 is fixedly connected to the limiting telescopic rod 9. The other end of the limiting telescopic rod 9 is fixedly connected to the fixed tooth plate 404. The fixed box 402 and the fixed block 501 are both provided with fixed through holes 10 that are compatible with the fixed rod 505. The front side of the fixed box 402 is provided with a movable slot that is compatible with the push plate 502. The anti-detachment plug 504 is fixedly connected to the fixed rod 505. The anti-detachment plate 503 is provided with an anti-detachment groove 11 that is compatible with the anti-detachment plug 504.

[0030] Specifically, the push rod 6 is used to push the adjusting tooth plate 401 to move vertically. The vertical plate 7 and the limiting vertical groove 8 limit the adjusting tooth plate 401, allowing it to move smoothly vertically. The connecting groove allows the fixed tooth plate 404 to enter the interior of the insulating operating plate 2. The limiting telescopic rod 9 limits the fixed tooth plate 404 to prevent it from shifting during movement. The fixing through hole 10 allows the fixing rod 505 to penetrate the inner wall of the fixing box 402 and insert into the fixing block 501 to limit the fixed tooth plate 404. The anti-detachment groove 11 allows the anti-detachment insert 504 to be inserted into the anti-detachment plate 503 to prevent the fixing rod 505 from slipping.

[0031] The operation process of this embodiment is as follows: The operator pushes the push rod 6 on the front side of the insulating operating plate 2. The push rod 6 drives the adjusting tooth plate 401 to move. The adjusting tooth plate 401 pushes the wire clamp 1 to clamp the conductor through the connecting rod 3. Then, the operator pushes the push plate 502. The push plate 502 drives the fixed tooth plate 404 to move towards the adjusting tooth plate 401, so that the fixed tooth plate 404 engages with the adjusting tooth plate 401 while stretching the spring 403.

[0032] Insert the fixing rod 505 into the fixing through hole 10 to fix the fixing block 501 and the fixing tooth plate 404. Rotate the fixing rod 505 so that the anti-detachment insert 504 on the fixing rod 505 is inserted into the anti-detachment groove 11. At this time, the push plate 502 and the fixing rod 505 are fixed to prevent the fixing rod 505 from accidentally slipping off during use and improve the safety of the grounding rod during use.
