Description

Technical Field

[0001] This utility model relates to the field of lightning protection device technology, and in particular to an overhead line lightning protection device. Background Technology

[0002] When installing overhead lines, which are usually located at a high position, it is usually necessary to install surge arresters at the top of the poles for lightning protection to prevent damage to the entire line caused by external lightning strikes.

[0003] However, existing surge arresters are usually divided into two parts: one supports the line at the center and the other supports the lines on both sides. Therefore, during installation, both surge arresters need to be carried up to the utility pole and installed one by one, which makes the installation inefficient and prolongs the time that personnel spend working at height. To address these issues, we propose an overhead line surge protection device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing an overhead line lightning protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An overhead line lightning protection device includes a mounting frame, which is L-shaped. Lightning arresters are fixedly installed on both sides of the mounting frame. A clamp is fixedly installed in the middle of the mounting frame by bolts. A support plate is fixedly installed in the middle of the top of the mounting frame. The top of the support plate is L-shaped, and a lightning arrester is placed on the top of the support plate. Two sets of surge arresters can be combined, allowing workers to carry fewer tools, making it easier for them to work at heights and thus improving work efficiency.

[0006] Preferably, both sides of the support plate are provided with rotating slots, and a fixing ring is movably installed inside the rotating slot via a rotating shaft; The fixed ring can be rotated to secure the utility pole. The synchronous fixing of the clamp and the fixed ring improves the overall stability of the device after installation.

[0007] Preferably, a connecting rod is fixedly installed at the bottom of the surge arrester above the support plate, and the connecting rod extends through the top of the support plate to the bottom of the support plate; The height of the surge arrester in the middle can be adjusted to adapt to different overhead line support conditions.

[0008] Preferably, a movable block is fixedly installed at the bottom end of the connecting rod, a sliding groove is provided on the side wall of the support plate, a positioning block is fixedly installed on the side wall of the movable block, and the positioning block extends into the interior of the sliding groove. This can improve the stability of the surge arrester in the middle position during height adjustment, preventing the arrester from shaking or detaching.

[0009] Preferably, a support shaft is fixedly installed inside the sliding slot, and the positioning block is sleeved on the outside of the support shaft; This further improves the stability of the surge arrester sliding as the connecting rod moves.

[0010] Preferably, a threaded drive rod is inserted inside the connecting rod, the bottom end of the threaded drive rod extends through the mounting frame to the bottom of the mounting frame, and the threaded drive rod is threadedly connected to the moving block and the connecting rod; By rotating the threaded drive rod, the threaded drive rod can drive the connecting rod to move through the threaded structure, making the movement of the connecting rod more convenient. At the same time, under the weight of the surge arrester, the connecting rod and the threaded drive rod are subjected to force to achieve thread self-locking.

[0011] Preferably, a servo motor is fixedly installed at the bottom end of the threaded transmission rod, and a positioning plate is fixedly installed on the outside of the threaded transmission rod, with the positioning plate located directly above the mounting frame; It can position the positioning plate and servo motor, thereby improving the stability of the threaded transmission rod rotation and preventing wobbling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can fix the support plate above the mounting frame, so that the three sets of surge arresters can be carried synchronously, which is more convenient for subsequent installation. At the same time, the installation of clamps and fixing rings makes the overall stability of the device better, thereby reducing the time required for personnel to work at height and improving work efficiency.

[0013] 2. This utility model can adjust the height of the surge arrester at the middle position by rotating the servo motor, which drives the threaded transmission rod to rotate, thereby lifting the connecting rod. This allows it to be used for supporting overhead lines under different conditions. Attached Figure Description
