[0023] Please see Figure 1-4 This utility model provides a technical solution for a three-dimensional grounding device for transmission line towers: it includes a first frame 1 and a second frame 2, which are matched and connected by a first connecting component 3. A second connecting component 4 is fixedly sleeved at the center of both the first frame 1 and the second frame 2. A conductive rod 5 is fixedly connected to the surface of the second connecting component 4. Limit openings 8 are opened at both ends of the first frame 1, and limit portions 9 are provided at both ends of the limit openings 8. The first connecting component 3 includes a fixedly connected corner sleeve 6 and an inner limit plate 7 inside it. The second connecting component 4 includes a fixedly connected fixing sleeve 10 and a guide seat 11. Locking seats 12 and sliding seats 13 are embedded at both ends of the guide seat 11. A locking portion 15 is provided on the inner end surface of the locking seat 12. A spring 16 and an adjusting screw 14 are respectively connected to the inner side of the locking seat 12 and the sliding seat 13. An installation head 17 is embedded at the top of the locking seat 12.
[0024] like Figure 3As shown, the limiting opening 8 is rectangular, and the limiting part 9 is horizontally protruding in a rectangle along both ends of the limiting opening 8. Threaded holes are provided on the surface of the limiting opening 8. Threaded holes are provided at both ends of the second frame 2 corresponding to the threaded holes on the surface of the limiting opening 8. At the same time, the bottom surfaces of both ends of the second frame 2 are horizontally toothed, and the surface of the limiting part 9 is horizontally toothed. It is fitted with the inner limiting plate 7. The corner sleeve 6 is L-shaped, hollow inside, and open at both ends. The inner limiting plate 7 is a horizontally toothed plate that fits against the inner wall of the corner sleeve 6 for fixed connection. The limiting opening 8 facilitates the fitting and connection of the first frame 1 and the second frame 2 within the corner sleeve 6. The limiting part 9 facilitates the stable connection of the first frame 1 inside the corner sleeve 6. The corner sleeve 6, in conjunction with the inner limiting plate 7, simultaneously connects the first frame 1 and the second frame 2.
[0025] When connecting the first frame 1 and the second frame 2, both outer ends are simultaneously inserted into the corner sleeve 6. The end of the first frame 1 with the limiting opening 8 is inserted into the corner sleeve 6. The limiting part 9 fits against the inner limiting plate 7 in the corner sleeve 6 to form a stable fit. Then, the outer end of the second frame 2 is inserted into the corner sleeve 6. The bottom surface of the outer end of the second frame 2 fits into the inner limiting plate 7 and is inserted into the limiting opening 8 at the same time, forming a connection with the first frame 1. Finally, the corner sleeve 6, the first frame 1 and the second frame 2 are fixed together by external screws.
[0026] like Figure 4 As shown, the fixed sleeve 10 is rectangular, the guide seat 11 has rectangular sides at its tail end and an arc-shaped front end, and two sets of locking seats 12 and sliding seats 13 are provided. The locking seats 12 and sliding seats 13 are respectively movably inserted into the front and tail ends of the guide seat 11 from the outside. The locking seat 12 is cylindrical and horizontally arranged, while the sliding seat 13 is rectangular. The locking part 15 is arc-shaped and located at the top of the inner end of the locking seat 12, and the inner side of the locking part 15 is arc-shaped and stepped. The spring 16 is fixedly connected to the bottom between the two sets of locking seats 12, and the adjusting screw 14 is movably connected between the two sets of sliding seats 13, causing the sliding seats 13 to move simultaneously with the screw. The connection is made so that one end of the adjusting screw 14 passes through the outside of one of the sliding seats 13. The top of the mounting head 17 is fixedly connected to the conductive rod 5. The bottom end of the mounting head 17 is set in a conical hourglass shape, which is also fitted with the locking part 15. The fixing sleeve 10 achieves the effect of facilitating the connection and fixation of the second connecting component 4 as a whole with the frame. The guide seat 11 achieves the effect of limiting the installation of the locking seat 12 and the sliding seat 13. The locking seat 12 and the sliding seat 13 cooperate with the locking part 15 to achieve the effect of clamping and fixing the mounting head 17. The adjusting screw 14 achieves the effect of adjusting the distance between the two sets of locking seats 12.
[0027] When connecting and fixing the conductive rod 5, rotate the adjusting screw 14 from the outside position. The adjusting screw 14 drives the two sets of locking seats 12 to move closer to each other, forming a clamp on the bottom end of the mounting head 17. The sliding seat 13 slides along the rectangular position at the tail end of the guide seat 11 to ensure the stable adjustment of the locking seat 12. The spring 16 adapts to the adjustment of the locking seat 12, compressing and extending until the locking seat 12 clamps and fixes the bottom end of the mounting head 17.
[0028] The working principle of this utility model is as follows: When this device is in use, the corner sleeve 6 and the inner limit plate 7 on the inner side are used to connect and fix the two sets of frames. While the corner sleeve 6 fixes the connecting end of the two sets of frames, the connecting end of the two sets of frames is connected at the same time in the corner sleeve 6 to ensure the stability of the frame connection. The locking seat 12 is used to lock and fix the mounting head 17, thereby realizing the installation and fixation of the conductive rod 5.
