[0002] Grounding rods, also known as grounding electrodes or grounding bars, are an indispensable part of electrical safety. Their main function is to conduct current from electrical equipment to the ground, ensuring the safe operation of the equipment. Grounding rods play a crucial role in lightning protection, electrostatic discharge protection, and power system stability.
[0003] According to a copper-clad aluminum grounding rod disclosed in the public notice (announcement number: CN203631749U), when used in the above application, it can improve conductivity and reduce costs, and is not easily corroded by underground layers, effectively extending the service life of the rod. It has the advantages of simple structure, reasonable setting, and low manufacturing cost.
[0004] However, although the above-mentioned devices can effectively conduct electricity in actual use, the copper and aluminum outer walls are too flexible and easily deformed when plugged in and unplugged, resulting in poor subsequent conductivity. In view of this, we propose a high-hardness copper-clad grounding rod. Utility Model Content

[0007] A grounding copper rod is disposed on the inner wall of an alloy cladding shell. An upper copper ring is fixedly connected to the outer wall of the grounding copper rod, and an outwardly protruding copper column is fixedly connected to the outer wall of the grounding copper rod.
[0008] Preferably, the center line of the upper port, the center line of the lower port, and the center line of the grounding copper rod are all on the same straight line.
[0009] Preferably, the number of external openings is several, and the several external openings are arranged in a circumferential array on the outer wall of the alloy shell.
[0010] Preferably, the size of the outer wall of the protruding copper column is adapted to the size of the inner wall of the external opening, so that the protruding copper column can be installed and fixed stably.
[0011] Preferably, the outer wall of the alloy cladding is provided with a positioning component, the positioning component including a spiral rotating plate, the spiral rotating plate being fixedly connected to the outer wall of the alloy cladding, and the bottom end of the grounding copper rod being fixedly connected to a lower copper column.

[0014] Compared with the prior art, this utility model provides a high-hardness copper-clad grounding rod, which has the following beneficial effects:
[0015] 1. This high-hardness copper-clad grounding rod can be used in daily operations by inserting the required grounding copper rod into the alloy cladding. Then, the appropriate protruding copper post can be installed on the grounding copper rod through the external through-hole. After that, the installed rod assembly can be inserted into the soil. During insertion, the alloy cladding ensures that the grounding copper rod will not deform, allowing it to be inserted into the soil more stably and firmly. The protruding copper post further increases the contact area between the grounding copper rod and the external soil, thereby further increasing the overall conductivity.

[0023] Furthermore, the grounding copper rod 204 is disposed on the inner wall of the alloy cladding 1, and the outer wall of the grounding copper rod 204 is fixedly connected to the upper copper ring 205, and the outer wall of the grounding copper rod 204 is fixedly connected to the protruding copper column 206.
[0024] In the embodiments of this utility model, the center line of the upper port 201, the center line of the lower port 203, and the center line of the grounding copper rod 204 are all on the same straight line. The number of external through holes 202 is several, and the several external through holes 202 are arranged in a circumferential array on the outer wall of the alloy shell 1. The size of the outer wall of the protruding copper column 206 is adapted to the size of the inner wall of the external through hole 202, so that the protruding copper column 206 can be installed and fixed stably.
[0025] Furthermore, the outer wall of the alloy cladding 1 is provided with a positioning component 3, which includes a spiral rotating plate 301. The spiral rotating plate 301 is fixedly connected to the outer wall of the alloy cladding 1. The bottom end of the grounding copper rod 204 is fixedly connected with a lower copper column 302. The center line of the spiral rotating plate 301 and the center line of the alloy cladding 1 are on the same straight line, so that the spiral rotating plate 301 can rotate smoothly. The number of lower copper columns 302 is several, and the several lower copper columns 302 are arranged in a circular array on the end of the grounding copper rod 204.

Then, the installed rod assembly can be inserted into the soil. During insertion, the alloy shell 1 ensures that the grounding copper rod 204 will not deform, allowing it to be inserted into the soil more stably and firmly. The protruding copper post 206 further increases the contact area between the grounding copper rod 204 and the external soil, thereby further increasing the overall conductivity.
