[0002] A grounding electrode refers to a conductor or a combination of several conductors buried in the earth for connection with the earth. A grounding electrode is a group of conductors or metal conductors in direct contact with the soil, which is divided into natural grounding electrodes and artificial grounding electrodes. As a conductor in direct contact with the earth's soil and providing an electrical connection with the earth, a grounding electrode safely dissipates lightning energy and discharges it into the earth.

[0003] Most traditional grounding electrodes are radial connection devices based on round steel materials. They not only occupy a large area and are difficult to construct in the limited space of urban areas, but also, as the operation time increases, the round steel will corrode, break, etc., resulting in the grounding resistance of the lightning protection grounding of operating power equipment not meeting the requirements. When there is a lightning strike on the distribution equipment, it is easy to damage the distribution equipment, further causing power outages; some use graphite mesh grounding electrodes, but this structure is not convenient for installation and assembly. If a certain component is damaged, the whole needs to be replaced, increasing costs. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0029] As Figures 1 to 5 shown, in a specific embodiment of the present invention, a flexible graphite grounding electrode assembly is disclosed, which includes a graphite mesh plug-in 100 and an installation pushing member 200. The graphite mesh plug-in 100 includes a graphite mesh body 110, a cone head structure 300 fixedly provided at the bottom end of the graphite mesh body 110, and a support head structure 400 fixedly provided at the top end of the graphite mesh body 110. The bottom end of the graphite mesh body 110 is bent inward to form a first clamping portion 120. The cone head structure 300 is clamped and fixedly matched with the first clamping portion 120. The top end of the graphite mesh body 110 is bent outward to form a second clamping portion 130. The support head structure 400 is clamped and fixedly matched with the second clamping portion 130. The installation pushing member 200 includes a tube body 210. The outer wall of the tube body 210 is adapted to the inner wall of the graphite mesh body 110. The tube body 210 is inserted into the graphite mesh body 110 to expand the graphite mesh body 110. A pressure ring 220 is fixedly provided on the outer wall of the tube body 210. The pressure ring 220 abuts against the support head structure 400. A horizontally arranged handle structure 500 is installed on the outer side of the top of the tube body 210.

[0030] For the above-mentioned flexible graphite grounding electrode assembly, the structure of the grounding electrode assembly is novel. The bottom end of the graphite mesh body 110 is clamped and fixedly connected with the cone head structure 300, and the top end is clamped and fixedly connected with the support head structure 400, which is convenient for production, processing and assembly, and also convenient for the replacement of subsequent components, reducing the use cost. The supporting installation pushing member 200 can facilitate the subsequent filling of native soil, effectively prevent the graphite mesh body 110 from collapsing during the process of pulling out the tube body 210, reduce the probability of secondary adjustment and installation, and thus improve the installation work efficiency of the grounding electrode.

[0031] Furthermore, the cone head structure 300 includes a cone body 310 and a fixing block 320. The fixing block 320 is in a columnar structure and is adapted to the inner wall of the graphite mesh body 110. A threaded column 330 is fixedly provided in the middle of the top surface of the cone body 310. A threaded hole corresponding to the threaded column 330 is opened on the bottom surface of the fixing block 320. The fixing block 320 is threadedly connected and cooperated with the cone body 310 and forms a clamping force on the first clamping portion 120. A card slot 340 for adapting to a screwdriver is opened in the middle of the top surface of the fixing block 320. This structural design facilitates the disassembly and assembly cooperation between the fixing block 320 and the cone body 310, enables quick disassembly and assembly, and can form a stable clamping force on the first clamping portion 120.

[0032] Further, a first magnet block 350 is embedded in the top of the fixing block 320, and both the pipe body 210 and the fixing block 320 are made of iron; this structural design enables a certain magnetic attraction effect to be formed between the fixing block 320 and the bottom end of the pipe body 210, facilitating subsequent support connection and preventing the graphite mesh plug-in 100 from easily falling off the installation pusher 200.

[0033] Further, the support head structure 400 includes a first annular plate 410 and a second annular plate 420. The inner wall of the first annular plate 410 is adapted to the shape of the graphite mesh body 110. A ring body is fixedly provided at the bottom of the inner wall of the first annular plate 410, and the ring body is adapted to the graphite mesh body 110. The second annular plate 420 is located above the first annular plate 410, and the second annular plate 420 is fixedly connected to the first annular plate 410 by screws and clamps the second clamping portion 130; this structural design facilitates the support head structure 400 to firmly clamp and fix the second clamping portion 130, and is convenient for disassembly and assembly.

[0034] Further, both the second annular plate 420 and the pressure ring 220 are made of iron, and a second magnet block 230 is embedded in the bottom of the pressure ring 220; this structural design enables a certain magnetic attraction effect to be formed between the pressure ring 220 and the second annular plate 420, facilitating subsequent support connection and preventing the graphite mesh plug-in 100 from easily falling off the installation pusher 200.

[0035] Further, the handle structure 500 includes a sleeve 510 and cross bars 520 fixedly provided on both sides of the sleeve 510. The sleeve 510 is in threaded connection and cooperation with the outer side of the top of the pipe body 210.

[0036] Further, a hopper 240 is installed at the top end of the pipe body 210, and the bottom end of the hopper 240 is in threaded connection and cooperation with the inner wall of the pipe body 210, facilitating the addition of filling materials.

[0037] The present invention also provides a method for using a flexible graphite grounding electrode assembly, including the following steps:

[0038] S1, find the installation position and mark it;

[0039] S2, insert the installation pusher into the graphite mesh plug-in. Under the action of the first magnet block, the bottom end of the pipe body is magnetically adsorbed to the fixing block. Under the action of the second magnet block, the pressure ring is magnetically adsorbed to the second annular plate;

[0040] S3, push the installation pusher to insert the graphite mesh plug-in into the corresponding position;

[0041] S4. Pour the plain soil into the hopper. The plain soil enters the interior of the graphite mesh body along the pipe body. Lift and lower the pipe body back and forth, and the plain soil drops into the interior of the graphite mesh body. During the process of lowering the pipe body, the plain soil is compacted until the pipe body completely disengages from the graphite mesh insert, completing the filling of the plain soil.

[0042] Further, when assembling the graphite mesh insert, first, the first clamping portion is sleeved on the outer side of the threaded rod, and then the fixing block is threadedly connected and matched with the cone, so that the cone head structure is fixedly connected to the bottom of the graphite mesh body; then, the first annular plate is sleeved on the top end of the graphite mesh body, the second clamping portion is attached to the top surface of the first annular plate, and then the second annular plate is fixed to the first annular plate by screws, thus completing the connection and cooperation between the support head structure and the graphite mesh body.

[0043] It should be noted that after the plain soil is filled, the plain soil provides a certain pressure support to the graphite mesh insert. At this time, when the installation push member is withdrawn, the pressure between the plain soil and the graphite mesh insert is sufficient to overcome the magnetic suction force generated by the first magnet block and the second magnet block, and the graphite mesh insert will not be driven to disengage from the soil.

[0044] The present invention is described by way of preferred embodiments. Those skilled in the art will know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application belong to the scope of protection of the present invention.
