Abstract
Description
Technical Field
[0001] This utility model relates to the field of grounding technology for power line towers, specifically a modular grounding device for power line towers. Background Technology
[0002] In areas with low soil resistivity, the grounding device for transmission line towers typically employs a grounding frame, a horizontal grounding ray, and grounding down conductors. The conventional installation method involves laying hot-dip galvanized round steel around the outer edge of the foundation of each of the four tower legs, forming a square frame. The horizontal grounding ray extends outwards from the four corners of the grounding frame, forming a windmill-like arrangement. Finally, grounding down conductors connect each of the four tower legs to the grounding frame. The grounding module is a grounding body primarily composed of carbon materials, consisting of non-metallic minerals with good conductivity and stability.
[0003] A search of the China Patent Network revealed a modular grounding device for transmission line towers (publication number: CN222463466U). This device adjusts the positions of multiple connecting rods to ensure that the connecting rods are positioned at a set interval, and that the grounding module bodies welded on the connecting rods are evenly distributed. Furthermore, the length of the grounding rays can be selected according to the soil resistivity, and then an appropriate number of grounding module bodies can be selected based on the soil resistivity to further ensure the grounding effect on the transmission tower.
[0004] However, the above-mentioned technical solution still has certain defects. The device has many inconveniences in actual installation and transportation. For example, during installation, the lack of an effective and quick connection mechanism between the various components leads to low installation efficiency, which increases construction time and cost. At the same time, during transportation, the overall structure of the grounding device is relatively large and the fixing between the components is not flexible enough, which results in a large space occupation and high transportation cost. Moreover, it is difficult to stack compactly during storage, which further increases warehousing costs. Therefore, a modular grounding device for power line towers is proposed. Utility Model Content
[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a modular grounding device for power line towers, which can effectively improve installation efficiency and reduce space occupation during transportation, facilitating transport and storage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular grounding device for a power collection line tower, comprising a power collection line tower body, wherein mounting components are provided at the outer corners of the four tower legs of the power collection line tower body;
[0007] The installation assembly includes a first galvanized steel strip connected to the outer corner of the main tower leg of the power collection line tower. A second galvanized steel strip is snapped onto one side of the first galvanized steel strip, and there are multiple sets of the first and second galvanized steel strips in a linear array. A fixing block is provided on the side of the second galvanized steel strip near the first galvanized steel strip. The fixing block has grooves on both sides inside, and a return spring is installed in each of the two sets of grooves. An inclined block is provided on one side of the return spring, and an abutment block is provided on the side of the inclined block away from the return spring. An insert plate is slidably connected to the side of the inclined block near the abutment block. A T-shaped clip is attached to the abutment block and installed on one side of the first galvanized steel strip.
[0008] As a preferred technical solution, a galvanized rod is provided directly above the first galvanized steel bar and the second galvanized steel bar. There are multiple sets of linear arrays of galvanized rods, and a counterweight is provided at the top of each set of galvanized rods. A plug is fixed at the bottom of each galvanized rod.
[0009] As a preferred technical solution, the bottom end of the insertion rod passes through the first galvanized steel strip and the second galvanized steel strip. The bottom of the first galvanized steel strip and the second galvanized steel strip are provided with a sliding groove. Multiple sets of T-shaped blocks are slidably connected inside the sliding groove. The bottom end of the T-shaped block is fixed with the grounding module body.
[0010] As a preferred technical solution, the T-shaped block is provided with a limiting rod inside, and the bottom end of the insertion rod extends into the T-shaped block to engage with the limiting rod.
[0011] As a preferred technical solution, an L-shaped connecting plate is fixed on the side of the insert plate away from the inclined block.
[0012] As a preferred technical solution, three sets of round rods are fixed on the side of the second galvanized steel strip close to the first galvanized steel strip, and the first galvanized steel strip has round holes inside for the round rods to be inserted.

When adjustment of the grounding module body is needed, simply pull out the corresponding set of galvanized rods and slide the corresponding T-shaped block to the appropriate position via the sliding groove to achieve the adjustment of the grounding module body's position, eliminating the need for large-scale disassembly of the entire grounding device and improving maintenance efficiency.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0024] The embodiments of this utility model will be described below based on its overall structure.
[0025] A modular grounding device for power transmission line towers, such as Figure 1-6 As shown, it includes a main body 100 of the power collection line tower, and installation components 200 are provided at the outer corners of the four tower legs of the main body 100 of the power collection line tower.
[0026] The mounting assembly 200 includes a first galvanized steel strip 210 connected to the outer corner of the tower leg of the main body 100 of the power collection tower. A second galvanized steel strip 220 is snapped onto one side of the first galvanized steel strip 210. Multiple sets of the first galvanized steel strip 210 and the second galvanized steel strip 220 are arranged in a linear array. A fixing block 230 is provided on the side of the second galvanized steel strip 220 near the first galvanized steel strip 210. Grooves 231 are provided on both sides inside the fixing block 230. A return spring 240 is installed in each of the two sets of grooves 231. An inclined block 250 is provided on one side of the return spring 240. An abutment block 260 is provided on the side of the inclined block 250 away from the return spring 240. An insert plate 270 is slidably connected to the side of the inclined block 250 near the abutment block 260. A T-shaped locking block 280 installed on one side of the first galvanized steel strip 210 is attached to the abutment block 260.
[0027] Workers weld and fix a set of first galvanized steel bars 210 to the main body 100 of the power transmission tower. Then, they align and press the second galvanized steel bar 220 with the first galvanized steel bar 210. When the T-shaped locking block 280 contacts the abutment block 260, continued force is applied, causing the T-shaped locking block 280 to press against the abutment block 260. The abutment block 260 then moves the inclined block 250 into the groove 231. During this movement, the inclined block 250 compresses the return spring 240. When the T-shaped locking block 280 completely passes the abutment block 260, the inclined block 250, under the elastic force of the return spring 240, moves the abutment block 260 back to its original position. At this point, the T-shaped locking block 280 is confined between the abutment block 260 and the fixing block 230, thus achieving the locking and fixing of the first galvanized steel bar 210 and the second galvanized steel bar 220. This design effectively improves installation efficiency. When disassembly is required, pushing the insert plate 270 causes the inclined block 250 to move into the groove 231, thereby separating the abutment block 260 from the T-shaped locking block 280. This allows the second galvanized steel strip 220 to be removed from the first galvanized steel strip 210, making the operation simple and quick. Furthermore, since there are multiple linear arrays of the first and second galvanized steel strips 210 and 220, the number and position of installations can be flexibly adjusted according to actual needs to meet the grounding requirements of the main body 100 of different specifications of power collection line towers. During the transportation of the first and second galvanized steel strips 210 and 220, they can be separated, reducing space occupation and facilitating transportation and storage. They can then be reassembled at the installation site.
[0028] Please refer to this carefully. Figure 1 , Figure 2 , Figure 4 and Figure 6 A galvanized rod 110 is provided directly above the first galvanized steel strip 210 and the second galvanized steel strip 220. There are multiple sets of galvanized rods 110 in a linear array. The top of the multiple sets of galvanized rods 110 is provided with a counterweight block 111, and the bottom of the galvanized rod 110 is fixed with an insertion rod 120. The bottom of the insertion rod 120 passes through the first galvanized steel strip 210 and the second galvanized steel strip 220. The bottom of the first galvanized steel strip 210 and the second galvanized steel strip 220 is provided with a sliding groove 211. Multiple sets of T-shaped blocks 130 are slidably connected inside the sliding groove 211. The bottom of the T-shaped block 130 is fixed with a grounding module body 140. The T-shaped block 130 is provided with a limiting rod 150. The bottom of the insertion rod 120 extends into the T-shaped block 130 and is sleeved with the limiting rod 150.
[0029] By setting a counterweight 111 on the galvanized rod 110, the stability of the overall structure can be enhanced, effectively preventing the galvanized rod 110 from shaking or shifting due to external forces, thereby ensuring the reliable connection of the grounding device. The insertion rod 120 and the limiting rod 150 are sleeved together to achieve tight fixation between the galvanized rod 110, the steel bar assembly and the grounding module body 140, ensuring that the grounding effect will not be affected by loosening during long-term use. At the same time, the sliding connection between the slide groove 211 and the T-block 130 allows the installation position of the grounding module body 140 to be flexibly adjusted according to the actual soil resistivity distribution. When it is necessary to adjust the grounding module body 140, simply pull out a set of galvanized rods 110 corresponding to the grounding module body 140, and slide the corresponding T-block 130 to the appropriate position through the slide groove 211 to achieve the position adjustment of the grounding module body 140. There is no need to disassemble the entire grounding device on a large scale, which greatly improves maintenance efficiency.
[0030] Please refer to this carefully. Figure 5 An L-shaped connecting plate 271 is fixed on the side of the insert plate 270 away from the inclined block 250.
[0031] By setting up the L-shaped connecting plate 271, the insertion plate 270 can be operated more easily, improving work efficiency and safety.
[0032] Please refer to this carefully. Figure 3 The second galvanized steel strip 220 has three sets of round rods 290 fixed on the side close to the first galvanized steel strip 210. The first galvanized steel strip 210 has round holes 291 inside for the round rods 290 to be inserted.
[0033] The combination of the round rod 290 and the round hole 291 makes the connection between the first galvanized steel strip 210 and the second galvanized steel strip 220 more stable, and enables quick positioning during installation and disassembly, thereby improving the overall stability and operability of the device.
