The protective assembly is sleeved on the outside of the top of the grounding electrode, and the outer bottom side of the protective assembly is threadedly connected to a threaded sleeve, and the top of the protective assembly is fixedly connected to the fixing assembly. In this utility model, the grounding electrode, the connecting block, and the grounding wire are protected by an outer sleeve and an inner protective layer to prevent them from being exposed to the air during use and prone to rust. By manually rotating the threaded sleeve, the threaded sleeve drives the conical block to move, compressing the bottom of the protective assembly to clamp inward, so that the elastic member contacts the outer wall of the grounding electrode, further sealing the grounding electrode. By manually rotating the handle, the screw is rotated, driving the clamping block and the sealing ring to move relative to each other, sealing and clamping the grounding wire, and keeping the interior of the protective assembly in a dry and sealed environment.

[0004] The above-mentioned existing technical solutions have the following defects: the upper end of the grounding electrode is a threaded structure, and the grounding electrode is rotated to connect it to the inside of the sleeve, but it is easy to fall off, resulting in an unstable installation structure.

At the same time, the grounding electrode needs to be manually installed on the ground, which is troublesome and difficult to adjust the height of the grounding electrode. Therefore, we propose an electrical engineering grounding device with enhanced stability to solve the above-mentioned problems. Utility Model Content

Therefore, this embodiment adopts the following technical solutions, such as Figure 1 、 Figure 2 and Figure 3 The outer end of the limit block 6 is engaged with the inner end of the limit hole 7, and the thickness of the limit block 6 and the minimum contraction length of the insulating spring 5 are equal to the depth of the mounting groove 4. Therefore, the mounting platform 2 is engaged with the inner end of the protective tube 8, and the grounding wire 1 is placed in the storage cavity 9. The upper end of the grounding wire 1 is nested in the hollow structure of the protective cover 11. After the mounting platform 2 enters the lower end of the grounding wire 1, the limit blocks 6 symmetrically arranged on the left and right correspond to the limit holes 7, and the two groups of insulating springs 5 ​​on the left and right drive the limit blocks 6 to slide toward the outer end inside the mounting groove 4, so that the outer ends of the limit blocks 6 symmetrically arranged on the left and right are engaged with the inner ends of the limit holes 7 at the corresponding positions. The position of the mounting platform 2 inside the lower end of the grounding wire 1 is limited by the limit blocks 6 and the limit holes 7, so that the grounding electrode 3 can be quickly installed in the protective tube 8, and the mounting structure is stable.

[0041] Example 2: The existing method of limiting the position of the fixed cover by bolts, nuts and other parts requires special tools to operate, which is troublesome and inconvenient.

The protective tube 8 forms a lifting structure on the inner side of the connecting plate 17 through the threaded rod 16 and the connecting rod 19. Therefore, the grounding electrode 3 is placed in the desired position, and the connecting plates 17 symmetrically arranged in front and back are fitted on the ground to allow the inserting rod to 18 is inserted into the ground, and the connecting plate 17 is simply limited by the insertion rod 18. There is a screw hole at the outer end of the connecting plate 17. The position of the connecting plate 17 on the ground is limited by the screw hole and the bolt. Turn to the threaded rod 16 to let the front connecting ear 15 drop on the connecting rod 19, and the rear connecting ear 15 drops on the threaded rod 16. The protective tube 8 is driven to drop by the front and rear symmetrical mounting strips 14 to adjust the position of the grounding electrode 3 on the ground, thereby easily adjusting the height of the grounding electrode 3. The above electrical components are all existing technologies and will not be described in detail here.
