Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a lightning protection device for State Grid transmission lines. Background Technology

[0002] As a core component of the power system, the operational stability of transmission lines directly affects the safety and reliability of power supply. Lightning disasters are one of the main causes of transmission line failures, so lightning protection devices have become an indispensable key protective equipment for transmission lines.

[0003] Existing lightning protection devices for power transmission lines lack a pre-positioning structure during installation, requiring repeated calibration of the connection position during connection and necessitating multiple people to work together during the fixing process. This not only results in low installation efficiency but also increases the risks associated with working at heights. Therefore, to address these issues, improve the efficiency and quality of power equipment, and reduce losses, this utility model has been developed. Utility Model Content

[0005] Preferably, the inner wall of the clamping block is fixedly connected to the outer wall of the stabilizing rod, and the anti-slip strip adopts an arc-shaped structure.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model sets up a pre-positioning structure, which adopts a combination design of a bidirectional lead screw and a symmetrical clamping block. Rotating the bidirectional lead screw can drive the clamping block to move symmetrically along the axial direction of the stabilizing rod.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0015] Example: Please see Figure 1 - Figure 2This utility model provides a technical solution: a lightning arrester device for State Grid transmission lines, comprising: a lightning arrester body 1, a connecting structure 3 fixedly connected to the bottom of the lightning arrester body 1, a pre-positioning structure 2 slidably connected to the inner wall of the connecting structure 3, the pre-positioning structure 2 including a support structure 21, the outer wall of the support structure 21 slidably connected to the inner wall of the connecting structure 3, a bidirectional lead screw 22 rotatably connected to the inner wall of the support structure 21, clamping blocks 23 symmetrically threaded to the outer wall of the bidirectional lead screw 22, and a stabilizing rod fixedly connected to the outer wall of the support structure 21. 24. An anti-slip strip 25 is fixedly connected to the end of the clamping block 23 away from the bidirectional lead screw 22. The inner wall of the clamping block 23 is fixedly connected to the outer wall of the stabilizing rod 24. The anti-slip strip 25 adopts an arc-shaped structure. When the bidirectional lead screw 22 of the prepositioning structure 2 is rotated, because the bidirectional lead screw 22 and the clamping block 23 are symmetrically threaded and the clamping block 23 is fixed to the stabilizing rod 24 of the support structure 21, the clamping block 23 will move symmetrically along the axial direction of the stabilizing rod 24 until the arc-shaped anti-slip strip 25 is tightly attached to the outer wall of the tower, thus completing the clamping and fixing of the prepositioning structure 2 and the tower. Then, the connecting structure 3 is pushed so that its inner wall slides along the outer wall of the support structure 21, driving the surge arrester body 1 to move synchronously to the installation position. At this time, the prepositioning structure 2 provides stable support for the entire device, preventing the surge arrester body 1 from shifting during installation.

[0016] Please see Figure 3 The support structure 21 includes a support frame 211. A stabilizing block 212 is fixedly connected to the top of the support frame 211. The outer wall of the stabilizing block 212 is slidably connected to the inner wall of the connecting structure 3. A fixing rod 213 is slidably connected to the inner wall of the stabilizing block 212. An adjusting block 215 is slidably connected to the outer wall of the stabilizing block 212. A stabilizing spring 214 is fixedly connected to the outer wall of the stabilizing block 212. One end of the stabilizing spring 214 away from the stabilizing block 212 is fixedly connected to the outer wall of the adjusting block 215. The fixing rod 213 passes through the stabilizing spring 214 and is fixedly connected to the outer wall of the adjusting block 215. When the stabilizing block 212 of the support structure 21 is aligned with the slide groove 32 of the connecting structure 3, the support frame 211 is pushed to make the stabilizing block 212 slide along the slide groove 32. During the sliding process, the adjusting block 215 is pulled, the stabilizing spring 214 is stretched, and the fixing rod 213 is stretched outward synchronously with the adjusting block 215. When the stabilizing block 212 slides to the target position, the fixing rod 213 aligns with the stabilizing hole 33 of the connecting structure 3, the adjusting block 215 is released, the stabilizing spring 214 resets and pushes the adjusting block 215, causing the fixing rod 213 to be inserted into the stabilizing hole 33, thereby achieving rapid fixation of the support structure 21 and the connecting structure 3.

[0017] Please see Figure 4The connecting structure 3 includes a connecting block 31. The top of the connecting block 31 is fixedly connected to the bottom of the surge arrester body 1. The outer wall of the connecting block 31 has a sliding groove 32 and a stabilizing hole 33. The inner wall of the sliding groove 32 is slidably connected to the outer wall of the stabilizing block 212, and the inner wall of the stabilizing hole 33 is slidably connected to the outer wall of the fixing rod 213. The top of the connecting block 31 is fixed to the bottom of the surge arrester body 1. First, the sliding groove 32 of the connecting block 31 is aligned with the stabilizing block 212 of the pre-positioning structure 2, so that the stabilizing block 212 slides along the sliding groove 32, completing the initial docking of the connecting block 31 and the support structure 21. After docking, the fixing rod 213 of the support structure 21 is inserted into the stabilizing hole 33 to fix the connecting block 31 and the support structure 21, thereby stabilizing the surge arrester body 1 in the pre-positioning position. Once the device is fully installed, press the adjusting block 215 to make the fixing rod 213 exit the stabilizing hole 33, push the support structure 21 to drive the prepositioning structure 2 to slide out of the slide groove 32, and the prepositioning structure 2 can be removed for the installation of the next device.

[0018] Working principle: In use, rotating the bidirectional lead screw 22 of the prepositioning structure 2 causes the clamping block 23 to move symmetrically along the axial direction of the stabilizing rod 24 of the support structure 21, as the bidirectional lead screw 22 is symmetrically threaded to the clamping block 23. The clamping block 23 is then fixed to the stabilizing rod 24 until the arc-shaped anti-slip strip 25 tightly adheres to the outer wall of the tower, completing the clamping and fixing of the prepositioning structure 2 to the tower. Subsequently, the connecting structure 3 is pushed, causing its inner wall to slide along the outer wall of the support structure 21, simultaneously moving the arrester body 1 to the installation position. At this point, the prepositioning structure 2 provides stable support for the entire device, preventing the arrester body 1 from shifting during installation. The stabilizing block 212 of the support structure 21 is aligned with the sliding groove 32 of the connecting structure 3, and the support frame 211 is pushed to make the stabilizing block 212 slide along the sliding groove 32. During the sliding process, the adjusting block 215 is pulled, the stabilizing spring 214 is stretched, and the fixing rod 213 is stretched outward synchronously with the adjusting block 215. When the stabilizing block 212 slides to the target position, the fixing rod 213 aligns with the stabilizing hole 33 of the connecting structure 3. The adjusting block 215 is released, and the stabilizing spring 214 resets, pushing the adjusting block 215 and causing the fixing rod 213 to insert into the stabilizing hole 33. This achieves rapid fixing of the support structure 21 and the connecting structure 3. The top of the connecting block 31 of the connecting structure 3 is fixed to the bottom of the arrester body 1. First, the sliding groove 32 of the connecting block 31 is aligned with the stabilizing block 212 of the pre-positioning structure 2, allowing the stabilizing block 212 to slide along the sliding groove 32, completing the initial docking between the connecting block 31 and the support structure 21. After docking, the fixing rod 213 of the support structure 21 is inserted into the stabilizing hole 33, fixing the connecting block 31 and the support structure 21, thereby stabilizing the arrester body 1 in the pre-positioning position. When the device is fully installed, pressing the adjusting block 215 causes the fixing rod 213 to exit the stabilizing hole 33, pushing the support structure 21 to slide the pre-positioning structure 2 out of the sliding groove 32. The pre-positioning structure 2 can then be removed for the installation of the next device.
