Description

Technical Field

[0001] This utility model relates to the field of surge arrester fixing technology, and in particular to a surge arrester fixing structure for transmission towers that resists lightning interference. Background Technology

[0002] In power systems, transmission towers play a crucial role, supporting high-voltage transmission lines and ensuring stable power transmission. However, transmission towers face numerous challenges during operation, among which lightning strikes are a significant threat. Lightning strikes can cause transmission line tripping, equipment damage, and even large-scale power outages, resulting in substantial losses to the social economy.

[0003] To protect transmission towers and related equipment from lightning strikes, surge arresters are essential devices. Traditional surge arresters for transmission towers are typically installed using threaded connections, a method with several drawbacks. Firstly, installation is time-consuming and labor-intensive, resulting in low efficiency. Secondly, disassembly is extremely inconvenient during subsequent maintenance and replacement, causing significant disruption to power system operation and maintenance. Therefore, we propose a lightning-resistant surge arrester fixing structure for transmission towers to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lightning arrester fixing structure for transmission towers that resists lightning interference.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightning arrester fixing structure for transmission towers resistant to lightning interference includes a frame. A hexagonal bearing seat is fixed to the upper end of the frame. A hexagonal mounting groove is provided inside the hexagonal bearing seat. A hexagonal support platform is inserted into the hexagonal mounting groove. The lightning arrester body is installed on the upper end of the hexagonal support platform. A stud is rotatably connected to the middle of the hexagonal support platform. A mounting plate is threaded onto the stud. A driving structure is connected to the lower end of the mounting plate. One end of the driving structure is connected to a plug-in mechanism. The plug-in mechanism penetrates the side walls of the hexagonal support platform and the hexagonal bearing seat. A rotating block is fixed to the upper end of the stud.

[0007] Preferably, a fixing plate is fixed on both sides of the hexagonal support base, and two through holes are provided on the fixing plate. A screw is installed in the through hole, and the lower end of the screw is connected to the upper end of the frame.

[0008] Preferably, the driving structure includes movable plates fixed to both sides of the lower end of the mounting plate, and rotating rods are rotatably connected to both sides of the movable plates. The two ends of the two rotating rods are connected by connecting rods, and a movable block is rotatably connected to one end of one rotating rod on the same side.

[0009] Preferably, the insertion mechanism includes a limiting rod fixed to one end of the moving block, and two limiting holes are provided on both sides of the hexagonal support base. The two limiting rods on the same side pass through the side wall of the hexagonal support platform and the two limiting holes and extend to one end of the hexagonal support base.

[0010] Preferably, the lower ends of the two movable blocks on the same side are fixed with a slider, and the bottom sides of the hexagonal support platform are provided with grooves, and a slider on the same side is installed in a groove on the same side.

[0011] Preferably, a cover is hinged to one side of the upper end of the hexagonal support platform, and the lower end of the surge arrester body is mounted on the upper end of the hexagonal support platform via a mounting base.

[0012] In this utility model, installation is required:

[0013] 1. Installation preparation: Before installation, the hexagonal support base is firmly fixed to the upper part of the frame with screws through the through holes on the fixing plate, which can ensure that the entire surge arrester fixing structure has a stable foundation.

[0014] 2. Loading platform insertion: Insert the hexagonal load platform into the hexagonal mounting groove inside the hexagonal load base. The hexagonal design ensures accurate alignment of the load platform and increases the contact area between the load platform and the load base, thereby improving the stability of the structure.

[0015] 3. Open the cover: Open the cover hinged on one side of the upper part of the hexagonal support platform to provide space for subsequent operations;

[0016] 4. Fixing Operation: Rotate the rotating block. Since the rotating block is fixedly connected to the stud, the rotation of the rotating block will drive the stud to rotate. The mounting plate threaded on the stud will move up and down with the rotation of the stud. The moving plate at the lower end of the mounting plate will also move accordingly. The rotating rods connected to both sides of the moving plate will rotate. Through the connection of the connecting rods, the moving block on the same side will slide in the slide groove. The limiting rod fixed at one end of the moving block will pass through the side wall of the hexagonal support platform and the limiting hole on the hexagonal support seat, thereby firmly fixing the hexagonal support platform and the hexagonal support seat together.

[0017] 5. Disassembly operation: When it is necessary to maintain or replace the surge arrester, reverse the rotating block to reverse the above process. The limit rod will then exit from the limit hole, and the hexagonal support platform can be removed from the hexagonal support base.

[0018] This utility model has the following advantages:

[0019] 1. Compared with the traditional threaded connection method, the fixing structure of this utility model can quickly fix and disassemble the bearing platform and the bearing seat by rotating the rotating block, which greatly shortens the installation time and improves work efficiency;

[0020] 2. During subsequent operation and maintenance, operators can easily disassemble the surge arrester body along with the hexagonal support platform from the frame for inspection or replacement, reducing operation and maintenance costs and difficulties.

[0021] 3. The design of the hexagonal support platform and the hexagonal mounting groove, as well as the plug-in fixing method of the limit rod and the limit hole, increases the stability and reliability of the structure, can better resist external interference such as lightning strikes, and ensure the safe operation of the transmission tower.

[0022] In summary, this utility model enables rapid fixing and disassembly of the support platform and support base, greatly shortening installation time and improving work efficiency. It allows for easy inspection or replacement of the surge arrester body, reducing operation and maintenance costs and difficulties. At the same time, it increases the stability and reliability of the structure, enabling it to better resist external interference such as lightning strikes and ensuring the safe operation of the transmission tower.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4The lightning arrester fixing structure for transmission towers resisting lightning interference includes a frame 18, with a hexagonal bearing seat 15 fixed at the upper end of the frame 18. The hexagonal bearing seat 15 has a hexagonal mounting groove 13, and a hexagonal bearing platform 9 is inserted into the hexagonal mounting groove 13. The geometric shape of the hexagon has high stability. Compared with common shapes such as quadrilaterals, it can distribute stress more evenly when bearing external forces, reducing the situation of excessive local stress. The hexagon has more sides, which can provide more contact points and contact surfaces when it is combined with the hexagonal bearing platform, thereby enhancing the overall stability of the structure.

[0030] The upper end of the hexagonal support platform 9 is equipped with the surge arrester body 10. The middle part of the hexagonal support platform 9 is rotatably connected with a stud 5. The stud 5 is threaded with a mounting plate 6. The lower end of the mounting plate 6 is connected to a driving structure. One end of the driving structure is connected to a plug-in mechanism. The plug-in mechanism passes through the side wall of the hexagonal support platform 9 and the hexagonal support seat 15. The upper end of the stud 5 is fixed with a rotating block 4. The threaded drive method has high precision and stability and can accurately control the position of the mounting plate 6.

[0031] Both sides of the hexagonal support base 15 are fixed with fixing plates 16. There are two through holes 17 on the fixing plates 16. Screws are installed in the through holes 17. The lower end of the screws is connected to the upper end of the frame 18. The driving structure includes movable plates 19 fixed on both sides of the lower end of the mounting plate 6. Both sides of the movable plate 19 are rotatably connected with rotating rods 2. The two ends of the two rotating rods 2 are connected by connecting rods 3. One end of one rotating rod 2 on the same side is rotatably connected to a movable block 7. When the mounting plate 6 moves up and down, it will drive the movable plate 19 to move synchronously, thereby causing the rotating rods 2 to rotate. Through the connecting action of the connecting rods 3, the movable block 7 is driven to move.

[0032] The insertion mechanism includes a limiting rod 1 fixed to one end of the moving block 7. Two limiting holes 14 are provided on both sides of the hexagonal support base 15. The two limiting rods 1 on the same side pass through the side wall of the hexagonal support platform 9 and the two limiting holes 14 and extend to one end of the hexagonal support base 15, so that the hexagonal support platform 9 and the hexagonal support base 15 can be tightly connected together, which enhances the integrity and stability of the structure.

[0033] The lower ends of the two movable blocks 7 on the same side are fixed with a slider. The bottom sides of the hexagonal support platform 9 are provided with grooves 8. One slider on the same side is installed in one groove 8 on the same side. The cooperation between the groove 8 and the slider plays a guiding and limiting role, ensuring that the movable block 7 can move smoothly along the predetermined trajectory.

[0034] A cover 12 is hinged to one side of the upper end of the hexagonal support platform 9. The lower end of the surge arrester body 10 is mounted on the upper end of the hexagonal support platform 9 via the mounting base 11. The cover 12 provides protection and is easy to open.

[0035] In this utility model, installation is required:

[0036] 1. Installation preparation: Before installation, the hexagonal bearing base 15 is firmly fixed to the upper end of the frame 18 through the through hole 17 on the fixing plate 16 with screws, which can ensure that the entire surge arrester fixing structure has a stable foundation.

[0037] 2. Insertion of bearing platform: Insert the hexagonal bearing platform 9 into the hexagonal mounting groove 13 in the hexagonal bearing seat 15. The hexagonal design can ensure accurate alignment of the bearing platform and increase the contact area between the bearing platform and the bearing seat, thereby improving the stability of the structure.

[0038] 3. Open the cover: Open the cover 12 hinged on one side of the upper end of the hexagonal support platform 9 to provide space for subsequent operations;

[0039] 4. Fixing Operation: Rotate the rotating block 4. Since the rotating block 4 is fixedly connected to the stud 5, the rotation of the rotating block 4 will drive the stud 5 to rotate. The mounting plate 6 threaded on the stud 5 will move up and down with the rotation of the stud 5. The moving plate 19 at the lower end of the mounting plate 6 will also move. The rotating rods 2 connected to both sides of the moving plate 19 will rotate. Through the connection of the connecting rod 3, the moving block 7 on the same side will slide in the slide groove 8. The limiting rod 1 fixed at one end of the moving block 7 will pass through the side wall of the hexagonal support platform 9 and the limiting hole 14 on the hexagonal support seat 15, thereby firmly fixing the hexagonal support platform 9 and the hexagonal support seat 15 together.

[0040] 5. Disassembly operation: When it is necessary to maintain or replace the surge arrester, reverse the rotating block 4 to reverse the above process. The limit rod 1 will exit from the limit hole 14, and the hexagonal support platform 9 can be removed from the hexagonal support seat 15.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
