For example, in areas with high soil resistivity, grounding wires with larger cross-sectional areas may be used to increase conductivity in order to reduce grounding resistance; while in some tower locations with strict requirements for spatial layout, grounding wires with smaller cross-sectional areas may be selected to adapt to installation space constraints.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0023] Reference Figures 1-6 As shown, this utility model provides a technical solution: a grounding device for transmission line towers, including a grounding device body 1; an adjusting column 2 is fixedly connected to the front end of the grounding device body 1; a control column 3 is rotatably connected inside the adjusting column 2; a connecting column 4 is provided inside the control column 3; a grounding wire 5 is installed at the bottom of the connecting column 4; limiting holes 6 are opened on both sides of the connecting column 4; arc grooves 7 are fixedly connected to both sides inside the adjusting column 2; control grooves 17 are opened on both sides of the control column 3; a push column 8 is slidably connected inside the control groove 17; a limiting rod 9 is fixedly connected to the side of the push column 8 away from the arc groove 7; the operator inserts the connecting column 4 into the control column 3; after the control column 3 is fully inserted, the operator rotates the control column 3, causing the control column 3 to drive the push column 8 to contact the arc groove 7; the arc groove 7 gradually pushes the push column 8 to drive the limiting rod 9 into the limiting hole 6, thus completing the fixing of the connecting column 4 and achieving the function of installing and replacing grounding wires 5 of different specifications.
[0024] Reference Figure 4 As shown in this embodiment, the surface of the limiting rod 9 is inserted into the interior of the limiting hole 6, and the size of the limiting rod 9 is adapted to the size of the limiting hole 6, so that the limiting rod 9 can be stably inserted into the limiting hole 6 and is not easy to fall out, thereby improving the stability and reliability of the device. At the same time, the insertion design of the limiting rod 9 and the limiting hole 6 also facilitates the quick installation and disassembly of the limiting rod 9, making it convenient for the maintenance and replacement of the device.
[0025] Reference Figure 3 and Figure 4As shown in this embodiment: Limiting holes 10 are provided on both sides of the adjusting column 2, and limiting grooves 11 are provided on both sides of the control column 3. A limiting rod 12 is slidably connected inside the limiting groove 11. A return spring 13 is fixedly connected to the side of the limiting rod 12 near the inside of the limiting groove 11. The side of the return spring 13 away from the limiting rod 12 is fixedly connected to the inside of the limiting groove 11. When the operator rotates the control column 3 to fully insert the limiting rod 9 into the inside of the limiting hole 6, the control column 3 drives the limiting groove 11 to be parallel to the limiting hole 10, and under the action of the return spring 13, it quickly pushes the limiting rod 12 into the inside of the limiting hole 10, thus limiting the control column 3 and preventing the control column 3 from rotating.
[0026] Reference Figure 4 As shown in this embodiment: guide grooves 14 are provided at both ends of the limiting groove 11, and guide blocks 15 are fixedly connected to both ends of the limiting rod 12. The surface of the guide block 15 is slidably connected to the inside of the guide groove 14. Through the setting of the guide groove 14 and the guide block 15, the two ends of the limiting rod 12 can reciprocate stably inside the limiting groove 11, which enhances the stability and flexibility of the device. At the same time, the sliding of the guide block 15 inside the guide groove 14 further ensures the smoothness and accuracy of the movement of the limiting rod 12, improves the overall performance of the device, and this design also helps to reduce friction and wear, and extend the service life of the device.
[0027] Reference Figure 4 As shown in this embodiment: a storage spring 16 is fixedly connected to the side of the push column 8 away from the arc groove 7. The side of the storage spring 16 away from the push column 8 is fixedly connected to the inside of the control groove 17. When the operator pushes the push column 8 to push the limiting rod 9, the push column 8 compresses the storage spring 16 to store force, and drives the limiting rod 9 to be inserted into the limiting hole 6. When the operator releases the push column 8, the limiting rod 9 is pushed out of the limiting hole 6 quickly under the action of the rebound force of the storage spring 16, and the push column 8 is reset. This design not only realizes the quick insertion and ejection of the limiting rod 9, but also improves the convenience and efficiency of operation through the compression and rebound of the storage spring 16.
[0028] Reference Figure 6 As shown in this embodiment: sliding grooves 18 are provided at both ends of the control groove 17, and sliding blocks 19 are fixedly connected to both ends of the push column 8. The surface of the sliding block 19 is slidably connected to the inside of the sliding groove 18. Through the setting of the sliding groove 18 and the sliding block 19, the push column 8 can also reciprocate stably at both ends inside the control groove 17. This design not only enhances the stability and flexibility of the device, but also the sliding of the sliding block 19 inside the sliding groove 18 further ensures the smoothness and accuracy of the push column 8's movement, thereby improving the overall working efficiency of the device.
[0029] Reference Figure 5 and Figure 6 As shown in this embodiment: two limiting grooves 20 are opened on the outer diameter surface of the control column 3, and two guide rings 21 are fixedly connected inside the adjusting column 2. When the operator rotates the control column 3, the limiting grooves 20 on the surface of the control column 3 slide along the guide rings 21, making the control column 3 more stable during rotation and avoiding grounding problems caused by shaking. At the same time, the setting of the guide rings 21 can also guide the rotation of the control column 3, ensuring the accuracy and reliability of the rotation.
[0030] Working principle: The operator inserts the connecting post 4 into the control post 3. After the control post 3 is fully inserted, the operator rotates the control post 3, causing it to drive the push post 8 to contact the arc groove 7. The arc groove 7 gradually pushes the push post 8, causing the limiting rod 9 to insert into the limiting hole 6, thus fixing the connecting post 4. This achieves the purpose of installing and replacing grounding wires 5 of different specifications, ensuring that the limiting rod 9 can be stably inserted into the limiting hole 6 without easily falling out, improving the stability and reliability of the device. Simultaneously, the insertion design of the limiting rod 9 into the limiting hole 6 facilitates the quick installation and removal of the limiting rod 9, making maintenance and replacement of the device easier for the operator. When the control column 3 is rotated so that the limiting rod 9 is fully inserted into the limiting hole 6, the control column 3 drives the limiting groove 11 to be parallel to the limiting hole 10. Under the action of the return spring 13, the limiting rod 12 is quickly pushed into the limiting hole 10, thus limiting the control column 3 and preventing it from rotating. The guide groove 14 and guide block 15 enable the limiting rod 12 to reciprocate stably at both ends inside the limiting groove 11, enhancing the stability and flexibility of the device. At the same time, the sliding of the guide block 15 inside the guide groove 14 further ensures the smoothness and accuracy of the movement of the limiting rod 12, improving the overall device. In addition to performance improvements, this design also helps reduce friction and wear, extending the device's lifespan. When the operator pushes the push column 8 to push the limiting rod 9, the push column 8 compresses the storage spring 16 to store energy, driving the limiting rod 9 into the limiting hole 6. When the operator releases the push column 8, the limiting rod 9 is quickly ejected from the limiting hole 6 under the rebound force of the storage spring 16, while the push column 8 returns to its original position. This design not only achieves rapid insertion and ejection of the limiting rod 9 but also improves operational convenience and efficiency through the compression and rebound of the storage spring 16. The sliding groove 18 and sliding block 19 further enhance the ease and efficiency of operation. The two ends inside the control groove 17 can also reciprocate stably. This design not only enhances the stability and flexibility of the device, but also ensures the smoothness and accuracy of the push column 8 movement by the sliding block 19 inside the sliding groove 18, thereby improving the overall working efficiency of the device. When the operator rotates the control column 3, the limiting groove 20 on the surface of the control column 3 slides along the guide ring 21, making the control column 3 more stable during rotation and avoiding grounding problems caused by shaking. At the same time, the guide ring 21 can also guide the rotation of the control column 3, ensuring the accuracy and reliability of the rotation.
