Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arresters, and specifically relates to a lightning arrester that is convenient for assembly. Background Art

[0002] The peeling device for power cables is a device specifically designed to remove the outer insulating layer of power cables. With the development of the power industry and technological progress, it is necessary to peel the power cables during installation, maintenance, and replacement in order to contact the conductors for connection or repair. In order to improve the peeling efficiency, reduce the labor intensity, and ensure safety, the peeling device for power cables came into being.

[0003] After retrieval, the existing patent (publication number: CN220156198U) discloses a lightning arrester that is convenient for assembly, which relates to the technical field of lightning arresters. Aiming at the problem that the existing strip-shaped lightning arrester fixed by bolts is prone to rust, which makes it inconvenient to disassemble when repairing and replacing the lightning arrester and affects the maintenance of maintenance workers, the following solution is proposed. It includes a base and a conductive strip. A sleeve is fixedly arranged on the top of the base. An adjusting rod is slidably arranged in the sleeve. An installation cylinder is fixedly arranged on the top of the adjusting rod. The conductive strip is movably arranged in the installation cylinder. A plurality of limiting holes are formed in the adjusting rod. An installation frame is fixedly arranged on the sleeve. The structure of the utility model is reasonably designed and easy to use. By arranging a waterproof box on the base, the waterproof function can be provided for the fixing bolts on the base, and thus the connection part between the fixing bolts and the base can be effectively prevented from rusting, which is convenient for workers to maintain.

[0004] However, in the actual use process of the above solution, the device can only be directly installed on the roof through the base. However, due to different house designs, different roofs may have different roof slopes, resulting in the installation angle of the tip in the lightning arrester not being perpendicular to the horizontal angle, thereby reducing the protection range and resulting in a decrease in the lightning protection effect.

[0005] Therefore, the utility model provides a lightning arrester that is convenient for assembly. Summary of the Utility Model

The outer side of the threaded sleeve 27 is fixedly connected with front and rear opposite connecting rods 22. The connecting rods 22 are fixed by the threaded sleeve 27. The outer side of the connecting rod 22 is fixedly connected with a slider 23. The slider 23 is fixed by the connecting rod 22. On the top end of the bottom plate 1, front and rear opposite limiting plates 2 are fixedly connected. The limiting plates 2 are fixed by the bottom plate 1. A sliding groove 21 is opened on the inner side of the middle end of the limiting plate 2. The sliding groove 21 is slidably connected with the connecting rod 22. The connecting rod 22 is limited by the sliding groove 21. The top end of the slider 23 is rotatably connected with a transmission rod 24. The bottom end of the transmission rod 24 is limited by the slider 23. The top end of the transmission rod 24 is rotatably connected with a mounting plate 12. The middle end of the mounting plate 12 is limited by the transmission rod 24. The bottom end of the right side of the mounting plate 12 is fixedly connected with a hinge 11. The bottom end of the hinge 11 is rotatably connected with the top end of the right side of the bottom plate 1. The bottom plate 1 and the mounting plate 12 are connected by the hinge 11. An installation component is arranged on the top end of the mounting plate 12. A lightning arrester inner tip 4 is arranged on the top end of the installation component.

[0026] The installation component includes a fixed sleeve 3. The fixed sleeve 3 is fixedly connected to the top end of the mounting plate 12. The fixed sleeve 3 is fixed by the mounting plate 12. A limiting ball 31 is slidably connected to the inner side of the middle end of the fixed sleeve 3. The limiting ball 31 is limited by the fixed sleeve 3. A limiting sleeve 32 is slidably connected to the outer side of the fixed sleeve 3. The limiting sleeve 32 is limited by the fixed sleeve 3. An extension chamber 34 is opened on the inner side of the top end of the limiting sleeve 32. The movement distance of the limiting ball 31 towards the outside is increased by the extension chamber 34. A clamping ring 33 is fixedly connected to the inner side of the top end of the limiting sleeve 32. The clamping ring 33 is fixed by the limiting sleeve 32. The clamping ring 33 is clamped and connected with the limiting ball 31. The limiting ball 31 is squeezed to clamp and fix the clamping ring 33, thereby preventing the limiting ball 31 from moving outwards. A spring 38 is fixedly connected to the outer side of the fixed sleeve 3. The bottom end of the spring 38 is fixed by the fixed sleeve 3. The top end of the spring 38 is fixedly connected with the bottom end of the clamping ring 33. The top end of the spring 38 is fixed by the clamping ring 33. A clamping column 36 is slidably connected to the inner side of the fixed sleeve 3. The clamping column 36 is limited by the fixed sleeve 3. A clamping groove 37 is opened on the outer side of the middle end of the clamping column 36. The clamping groove 37 is clamped and connected with the limiting ball 31. The fixed sleeve 3 and the clamping column 36 are fixed by the mutual clamping of the limiting ball 31 and the clamping groove 37.

[0027] A threaded ring 35 is fixedly connected to the outer side of the top end of the clamping post 36. The threaded ring 35 is fixed by the clamping post 36. The threaded ring 35 is in threaded connection with the inner side of the top end of the limiting sleeve 32. The internal thread inside the limiting sleeve 32 cooperates with the external thread outside the threaded ring 35, so as to drive the limiting sleeve 32, the clamping ring 33 and the range extender chamber 34 to move up and down when the limiting sleeve 32 rotates, thereby controlling the clamping of the limiting ball 31.

[0028] The threaded ring 35 is fixedly connected to the inner tip 4 of the lightning arrester. The inner tip 4 of the lightning arrester is fixed by the threaded ring 35.

[0029] Evenly distributed rotating blocks 39 are fixedly connected to the outer side of the bottom end of the limiting sleeve 32. The rotating blocks 39 are fixed by the limiting sleeve 32. The friction is increased by adding the rotating blocks 39 to facilitate the rotation of the limiting sleeve 32.

[0030] A hydrophobic layer is arranged on the outer surface of the lead screw 26 to prevent water droplets from remaining on the surface of the lead screw 26 and causing rust on the surface of the lead screw 26.

[0031] Working principle: When the lightning arrester that is convenient for assembly is operating, first install the bottom plate 1 at a specific position, and then drive the lead screw 26 to rotate through the motor 25, so as to drive the threaded sleeve 27, the connecting rod 22 and the slider 23 to move left and right through the lead screw 26. At the same time, the transmission rod 24 is driven to move synchronously through the slider 23, and the mounting plate 12 is driven to rotate around the connection point of the hinge 11 itself as the center by the transmission of the transmission rod 24, so as to adjust the angle of the mounting plate 12. Then pull the limiting sleeve 32 downward, and then insert the inner tip 4 of the lightning arrester together with the clamping post 36 and the threaded ring 35 into the inside of the fixed sleeve 3 and the limiting sleeve 32. Then drive the limiting sleeve 32 to rotate by rotating the rotating block 39. The internal thread inside the limiting sleeve 32 cooperates with the external thread outside the threaded ring 35, so as to drive the limiting sleeve 32, the clamping ring 33 and the range extender chamber 34 to move upward when the limiting sleeve 32 rotates. The limiting ball 31 is squeezed by the clamping ring 33, forcing the limiting ball 31 to move inward and engage with the clamping groove 37, completing the clamping and fixing between the fixed sleeve 3 and the clamping post 36.
