Description

Technical Field

[0001] This utility model relates to the field of grounding bolt technology, specifically a grounding bolt for power engineering. Background Technology

[0002] The waterproof design of the grounding bolt effectively prevents rainwater from directly wetting the grounding bolt body and clamping bolts, thereby preventing corrosion and extending its service life. The grounding bolt can reduce electromagnetic interference and improve the stability of the electrical system. By effectively connecting the equipment to the earth, the grounding bolt can balance the system potential, reduce electromagnetic interference, and improve the stability and reliability of the system. The grounding bolt plays an important role in the power system and can ensure the normal operation of electrical equipment.

[0003] For example, the grounding bolt for power engineering disclosed in the authorization announcement number CN222365740U includes a grounding bolt body and a grounding terminal. The bottom end of the grounding bolt body has a conical portion. The upper outer wall surface of the grounding bolt body is recessed to form a mounting concave surface that satisfies the requirement that the grounding terminal is semi-embedded. A mounting component for fixing the grounding terminal is provided at the center of the mounting concave surface.

[0004] While it can help limit the position of the grounding terminal, it can also increase the contact area between the grounding bolt body and the grounding terminal, thereby improving the subsequent grounding effect. It can also make it easy to insert the whole into the soil, while ensuring the combination effect with the grounding terminal. The grounding terminal can be installed on the threaded rod and fixed with a nut, making the assembly simpler and reducing the overall assembly time.

[0005] However, this does not solve the problem that existing grounding bolts of this type are generally not conducive to the convenient rotation of the grounding bolt to support multiple sets of ground wires, which affects the convenience of the grounding bolt's rotation position for supporting multiple sets of ground wires, and also hinders the convenient storage and release of the grounding bolt. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A grounding bolt for power engineering includes a bracket and a support plate. The support plate is installed inside the bracket, and a support column is installed inside the top of the bracket, extending through the bracket to the outside. A first telescopic column is installed at the top of the support column. A rotating disk is movably disposed on the surface of the first telescopic column, and a first pin is movably mounted on the surface of the rotating disk. Multiple sets of equally spaced first through holes are provided on the side wall of the first telescopic column, and the first pin extends through the first through holes to the outside of the rotating disk. Three sets of equally spaced U-shaped frames are installed on the side wall of the rotating disk, and first tightening bolts are movably mounted on the side wall of the U-shaped frames. An auxiliary plate is provided on the outside of the U-shaped frames, and a support shaft is fitted onto the surface of the auxiliary plate.

[0009] Optionally, the auxiliary plate is movably connected to the U-shaped frame via a support shaft, and the first tightening bolt contacts the auxiliary plate via the U-shaped frame.

[0010] Optionally, two sets of first buckles are symmetrically installed on the side of the auxiliary plate away from the support shaft, and a retaining ring is provided between each set of first buckles.

[0011] Optionally, a grounding bolt body is movably installed at the center of the support plate, the grounding bolt body extends through the support plate to its outside, and a plurality of equally spaced second through holes are provided on the side wall of the grounding bolt body.

[0012] Optionally, a second pin is movably installed on the side wall of the support plate, the second pin extending through the second through hole to the outside of the support plate, and three sets of telescopic cylinders with equal spacing are installed at the top of the outer support plate of the U-shaped frame.

[0013] Optionally, a second telescopic column is slidably installed inside each of the telescopic cylinders, and a roller is installed at the bottom end of each of the second telescopic columns.

[0014] Optionally, a second tightening bolt is movably installed on the side wall of the telescopic cylinder. The second tightening bolt extends into the interior of the first telescopic column and contacts the second telescopic column. A third buckle is provided on the outside of the grounding bolt body. A rotating shaft is movably installed on one side of the third buckle.

[0015] Optionally, a second latch is provided on the outside of the rotating shaft. The second latch is movably connected to a third latch via the rotating shaft, and a rotating shaft is movably mounted on the side of the second latch away from the rotating shaft.

[0016] Optionally, a threaded rod is mounted on the surface of the rotating shaft, and a threaded sleeve is provided on the outside of the third buckle.

[0017] Optionally, the threaded rod is threadedly connected to the threaded sleeve, and a terminal block is installed on the side of the second buckle near the rotating shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the grounding bolt not only realizes the convenient rotation position of the grounding bolt to support multiple sets of ground wires, improving the convenience of the grounding bolt rotation position for multiple sets of ground wires, but also realizes the convenient storage and release of the grounding bolt, improving the convenience of the grounding bolt storage and release.

[0019] Move the grounding bolt for power engineering to the work area, pull out the first pin to disengage it from the first through hole, pull the rotating disk to move it to the required height outside the first telescopic column, insert the first pin, and fix the rotating disk to the first through hole. Move the rotating disk and U-shaped frame to a certain height for operation. Tighten multiple sets of first tightening bolts to disengage them from the auxiliary plate.

This facilitates convenient rotation and support of multiple sets of ground wires, improving the convenience of the grounding bolt's rotation position for supporting multiple sets of ground wires.

[0020] Pull out the second pin, disengaging it from the second through hole. Pull the grounding bolt body upwards to a certain height, lifting it off the ground. Insert the second pin into the second through hole, fixing it in place. Tighten the second tightening bolt, disengaging it from the second telescopic column. This causes the second telescopic column to move the roller downwards, bringing it into contact with the ground. The bracket then lifts off the ground. Tighten the second tightening bolt. Tighten the threaded sleeve, disengaging it from the threaded rod. Supported by the rotating shaft, the third and second latches rotate, loosening the grounding bolt body. Open the terminal block to remove multiple ground wires, facilitating convenient storage and release of the grounding bolt. This improves the ease of grounding bolt storage and release.
