[0026] In an embodiment of the utility model, the shell cover 3 is slidably connected to the base 1, and the electronic equipment is installed on the shell cover 3. When it is necessary to maintain and inspect the grounding component in the base 1, the shell cover 3 can be pulled outward. After pulling outward, the other end of the shell cover 3 can be supported by a support body such as bricks.

[0027] The non-magnetic steel pipe 4 used in the utility model has good non-magnetic conductivity. The non-magnetic steel pipe 4 will not generate an induced magnetic field in a magnetic field, and will not generate eddy current loss. Therefore, the non-magnetic steel pipe 4 can prevent the magnetic field from interfering with the normal operation of the equipment.

When the resistance reducing agent is injected into the non-magnetic steel pipe 4, the resistance reducing agent will flow outward along the through hole 13 on the non-magnetic steel pipe 4, so that the outer wall of the non-magnetic steel pipe 4 and the ground are filled with the resistance reducing agent. The resistance reducing agent is composed of a variety of components, including fine graphite, bentonite, curing agent, lubricant, conductive cement, etc., and is generally gray-black. It is a good conductor. When used between the rod and the soil, on the one hand, it can be in close contact with the metal grounding rod 14 to form a sufficiently large current flow surface; on the other hand, it can penetrate into the surrounding soil, reduce the resistivity of the surrounding soil, and form a smoothly changing low-resistance area around the grounding rod 14.

[0034] In one embodiment of the present invention, Figure 1 As shown, a wire hole 18 is formed through the shell cover 3, and a wire groove 19 is formed on the end face of the shell cover. The wire groove 19 is connected to the wire hole 18.
