[0002] With the widespread application of electronic devices in modern society and the continuous development of various buildings, power facilities, and communication networks, the importance of lightning protection and grounding has become increasingly prominent. This has led to the development of copper-clad steel grounding rods. Combining the advantages of copper and steel, a layer of copper is clad around a steel core. The copper layer provides excellent conductivity and corrosion resistance, enabling the grounding rod to maintain low grounding resistance and a long service life in various soil environments; while the steel core gives the grounding rod high mechanical strength, allowing it to withstand certain installation stresses and external forces such as soil pressure.

[0003] Currently, some copper-clad steel grounding rods are connected to the down conductors by welding. This method is relatively complicated, prone to operational errors, and very troublesome for subsequent inspection and maintenance. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example: This example provides a convenient copper-clad steel grounding rod. See [link / reference]. Figure 1-4 Specifically, the grounding rod body 1 has an outer copper body and an inner steel core, and also includes:

[0026] A fixing sleeve 11 is fixedly installed on the upper end of the grounding rod body 1. A copper plate 12 is inserted into the fixing sleeve 11 for connecting the down conductor. The fixing sleeve 11 is fixedly installed at the upper end of the grounding rod body 1, and the upper end of the fixing sleeve 11 is flush with the upper end of the grounding rod body 1. The copper plate 12 inserted into the fixing sleeve 11 is U-shaped. The down conductor passes through the inside of the copper plate 12 and is in close contact with the upper end of the grounding rod body 1, which facilitates the conduction of electricity to the ground and improves the connection speed between the down conductor and the grounding rod body 1. The copper plate 12 is made of copper, which provides good conductivity and corrosion resistance.

[0027] A rotating ring 13 is fitted onto the grounding rod body 1. A connecting ring 14 is rotatably provided at the upper end of the rotating ring 13. The connecting ring 14 is connected to one end of the copper sheet 12 to tighten the copper sheet 12. One end of the copper sheet 12 is connected to the connecting ring 14. After the down conductor is connected to the grounding rod body 1, the rotating ring 13 is held and the grounding rod body 1 is inserted into the ground. When the grounding rod body 1 enters the ground, the rotating ring 13 will also move downward along the grounding rod body 1. The rotating ring 13 drives the connecting ring 14 to move downward synchronously. The connecting ring 14 pulls one end of the copper sheet 12, so that the copper sheet 12 surrounds the down conductor and firmly fixes the down conductor to the position of the grounding rod body 1. The outer wall of the rotating ring 13 is provided with anti-slip texture to increase friction and facilitate the insertion of the grounding rod body 1 into the ground.

[0028] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a mounting groove 2 is provided on one side of the fixing sleeve 11, one end of the copper sheet 12 is inserted into the mounting groove 2, and a round hole 21 is provided at the end of the copper sheet 12. A bolt 22 is threaded on the outer wall of one side of the fixing sleeve 11, and the bolt 22 passes through the round hole 21.

[0029] After one end of the copper sheet 12 is inserted into the mounting groove 2, the bolt 22 is rotated so that one end of the bolt 22 enters the mounting groove 2 and passes through the round hole 21 on the copper sheet 12 to fix the position of one end of the copper sheet 12, so as to facilitate the connection between the copper sheet 12 and the fixing sleeve 11.

[0030] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a connecting groove 3 is provided on the other side of the fixing sleeve 11, the other end of the copper sheet 12 passes through the connecting groove 3, a slot 31 is provided at the end of the copper sheet 12, and an L-shaped locking block 32 is fixed on the outer wall of the connecting ring 14, the locking block 32 is connected to the slot 31.

[0031] The other end of the copper sheet 12 passes through the connecting groove 3, turning the copper sheet 12 into a U-shape. The lower end of the copper sheet 12 passing through the connecting groove 3 is fitted onto the locking block 32. Since the locking block 32 is L-shaped, after the locking groove 31 is fitted onto the locking block 32, the other end of the copper sheet 12 is fixed onto the connecting ring 14. The setting of the locking block 32 and the locking groove 31 facilitates the disassembly and installation of the copper sheet 12.

[0032] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a positioning rod 4 is fixedly provided on the upper surface of the rotating ring 13, and a positioning groove 41 is provided at the lower end of the fixing sleeve 11, with the top of the positioning rod 4 located in the positioning groove 41;

[0033] The positioning rod 4 is located in the positioning groove 41 and is used to control the distance between the fixing sleeve 11 and the connecting ring 14. By positioning the positioning rod 4 at different positions in the positioning groove 41, the size of the contraction of the copper sheet 12 can be controlled, which facilitates fixing with lead wires of different thicknesses.

[0034] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the positioning groove 41 includes a placement groove 411, a low groove 412 and a deep groove 413. The low groove 412 and the deep groove 413 are located on both sides of the placement groove 411, and the heights of the placement groove 411, the low groove 412 and the deep groove 413 are all different.

[0035] The positioning rod 4 is initially located in the placement groove 411. When it is necessary to tighten the copper sheet 12, the rotating ring 13 is pulled, which drives the connecting ring 14 to move downward. The connecting ring 14 then pulls one end of the copper sheet 12 downward. The rotating ring 13 simultaneously drives the positioning rod 4 to move downward along the placement groove 411. The height of the positioning rod 4 is controlled by the thickness of the guide wire. Rotating the rotating ring 13 moves the positioning rod 4 from the placement groove 411 to the lower groove 412 and the deeper groove 413 on both sides. Since the inner walls of the lower groove 412 and the deeper groove 413 are at different heights, the degree of tightening of the copper sheet 12 is different.

[0036] In the specific implementation process, such as Figure 2 and Figure 3 As shown, an arc-shaped groove 5 is provided on the inner side of the connecting ring 14, and the positioning rod 4 passes through the arc-shaped groove 5. The arc-shaped groove 5 facilitates the rotation of the positioning rod 4. Since the rotating ring 13 and the connecting ring 14 are rotatably connected, when the rotating ring 13 drives the positioning rod 4 to rotate, the connecting ring 14 will not rotate accordingly.

[0037] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the outer wall of the fixing sleeve 11 is symmetrically provided with a connecting frame 6 and a connecting block 61, and the connecting block 61 has the same shape as the inner wall of the connecting frame 6;

[0038] When carrying multiple grounding rod bodies 1, insert the connecting block 61 on the fixing sleeve 11 into the connecting frame 6 on another fixing sleeve 11, such as... Figure 4 The grounding rod body 1 is spliced ​​into a ring shape, which makes it convenient to carry the grounding rod body 1.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
