An insulator grading ring for an extra-high voltage transmission line

Abstract

This utility model discloses an equalizing ring for insulators of ultra-high voltage transmission lines, relating to the technical field of high voltage cable equipment. The utility model includes a first connecting rod, with a positioning block fixedly connected to its outer wall. By setting a first fixed rod and a locking block, the positioning rod moves during the movement of the pressure plate, simultaneously moving the first fixed rod. The movement of the positioning rod causes a first limiting rod to move along the inside of a first limiting groove, thereby changing the movement range of the positioning rod. This allows the first limiting rod to push the positioning rod to rotate around the pressure plate while simultaneously locking the locking block. This achieves the goal of inserting the first fixed rod into the locking block through rotation, preventing the connection from loosening due to excessively simple fixing methods over long-term use caused by continuous external impacts, thus reducing the overall service life of the device and increasing operating costs.

Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage cable equipment, and in particular relates to an equalizing ring for insulators of ultra-high voltage transmission lines. Background Technology

[0002] According to the published patent CN218299489U, an equalizing ring for an insulator in an ultra-high voltage transmission line is described. The ring has a C-shaped structure, with symmetrically welded support frames on its lower surface. These support frames have a Z-shaped structure, with one end close to the center of the ring. The tops of two sets of support frames are welded to both ends of a fixing clip. A movable clip is movably provided on one side of the fixing clip. A sealing assembly includes an arc-shaped insertion groove, an arc-shaped sealing ring, a push handle, and an arc-shaped moving groove. The arc-shaped insertion grooves are symmetrically located at the opening of the ring. One set of arc-shaped insertion grooves has an arc-shaped sealing ring movably positioned within its inner cavity. This design addresses the issue of cumbersome installation and removal of the equalizing ring during installation or disassembly, as it requires disassembling the insulator. However, it also has the following shortcomings:

[0003] After the above equipment is completed, it is simply installed by pulling the arc-shaped closed ring. However, due to the overly simple fixing method, the connection at the joint is prone to loosening due to continuous external impacts during long-term use, which leads to a reduction in the overall service life of the equipment and an increase in operating costs. Utility Model Content

[0004] The purpose of this utility model is to provide an equalizing ring for insulators of ultra-high voltage transmission lines. Through the installation mechanism and clamping mechanism, it solves the problem that due to the simple fixing method, the connection at the joint is prone to loosening due to continuous external impacts during long-term use, which leads to a reduction in the overall service life of the device and an increase in the cost of use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an insulator equalizing ring for ultra-high voltage transmission lines, including a first connecting rod, a positioning block fixedly connected to the outer wall of the first connecting rod, and a second connecting rod fixedly connected to the outer wall of the positioning block on the side away from the first connecting rod.

[0007] The outer wall of the first connecting rod is provided with an installation mechanism, which includes a first hollow block. The inner wall of the first hollow block is slidably connected to a first extended arc rod. The outer wall of the first extended arc rod is fixedly connected to an installation block. The inner wall of the installation block is fixedly connected to a pressure spring. The outer wall of the pressure spring away from the installation block is fixedly connected to a pressure plate. The outer wall of the pressure plate is rotatably connected to a plurality of positioning rods. The inner wall of the positioning rod is provided with a first limiting groove. The inner wall of the first limiting groove is slidably connected to a first limiting rod. The outer wall of the positioning rod is rotatably connected to a first fixing rod. The inner wall of the installation block is slidably connected to a locking block. The outer wall of the locking block is fixedly connected to a second extended arc rod.

[0008] Furthermore, the outer wall of the second extended arc rod is slidably connected to a second hollow block, the outer wall of the first fixing rod is engaged with the inner wall of the locking block, the outer wall of the first limiting rod is fixedly connected to the inner wall of the mounting block, the outer wall of the second hollow block is fixedly connected to the outer wall of the second connecting rod, and the outer wall of the positioning block is provided with a clamping mechanism.

[0009] Furthermore, the clamping mechanism includes a second fixing rod, the outer wall of which is fixedly connected to the inner wall of the positioning block, and a sliding groove is provided on the inner wall of the second fixing rod, with a first extension rod slidably connected to the inner wall of the sliding groove.

[0010] Furthermore, a resistance spring is fixedly connected to the top outer wall of the first extension rod, and the outer wall of the resistance spring is fixedly connected to the inner wall of the second fixed rod.

[0011] Furthermore, a connecting plate is fixedly connected to the outer wall of the end of the first extension rod away from the resistance spring, and a plurality of fixed plates are rotatably connected to the outer wall of the connecting plate, and an insulating plate is fixedly connected to the outer wall of the plurality of fixed plates.

[0012] Furthermore, a second limiting rod is rotatably connected to the outer wall of the fixed plate, a second limiting groove is provided on the inner wall of the second limiting rod, a spring is fixedly connected to the inner wall of the second limiting rod, and a second extension rod is fixedly connected to the outer wall of the end of the spring away from the second limiting rod.

[0013] Furthermore, the outer wall of the second extension rod is slidably connected to the inner wall of the second limiting groove, the outer wall of the second extension rod is rotatably connected to the outer wall of the first connecting rod, and the outer wall of the second extension rod is rotatably connected to the outer wall of the second connecting rod.

[0014] Furthermore, a support rod is rotatably connected to the outer wall of the second limiting rod, and a connecting seat is rotatably connected to the outer wall of the end of the support rod away from the second limiting rod. The outer wall of the connecting seat is fixedly connected to the outer wall of the positioning block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a first fixed rod and a locking block. During the movement of the pressure plate, the positioning rod is pushed and simultaneously the first fixed rod moves. The movement of the positioning rod causes the first limiting rod to move along the inside of the first limiting groove, thereby changing the movement range of the positioning rod. This allows the first limiting rod to push the positioning rod to rotate around the pressure plate while locking the locking block. This achieves the goal of inserting the first fixed rod into the locking block through rotation, preventing the locking mechanism from loosening due to excessively simple fixing methods during prolonged use, which could lead to a reduced overall lifespan and increased operating costs.

[0017] 2. This utility model incorporates a spring and a fixing plate. The rotation of the second extension rod causes it to move along the second limiting groove inside the second limiting rod. Simultaneously, the second extension rod pushes the second limiting rod to rotate, causing the fixing plate to rotate around the connecting plate. This brings the two fixing plates closer together, clamping the wire while an insulating plate separates the fixing plate from the wire. As the second extension rod moves along the interior of the second limiting rod, it compresses the spring inside the second limiting rod. The spring's elasticity increases the pressure of the second limiting rod on the fixing plate, thus securing the wire more firmly. This increases the pressure of the second limiting rod on the fixing plate through the spring, preventing problems caused by rudimentary fixing methods or different cable sizes used in different regions, which could lead to unstable connections between the device and the cable and reduced device performance.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is an insulator equalizing ring for ultra-high voltage transmission lines, including a first connecting rod 1, a positioning block 101 fixedly connected to the outer wall of the first connecting rod 1, and a second connecting rod 102 fixedly connected to the outer wall of the positioning block 101 away from the first connecting rod 1. By setting the first connecting rod 1 and the second connecting rod 102 at both ends of the positioning block 101, it is convenient to install the device on the outside of the wire.

[0029] An installation mechanism 2 is provided on the outer wall of the first connecting rod 1. The installation mechanism 2 includes a first hollow block 201. A first extension arc rod 202 is slidably connected to the inner wall of the first hollow block 201. An installation block 203 is fixedly connected to the outer wall of the first extension arc rod 202. By operating the installation block 203, the first extension arc rod 202 is moved and extended inside the first hollow block 201. A pressure spring 204 is fixedly connected to the inner wall of the installation block 203. The pressure spring 204 is located away from the installation block 203. A pressure plate 205 is fixedly connected to the outer wall of the pressure plate 205. The movement of the pressure plate 205 compresses the pressure spring 204, thereby using the elasticity of the pressure spring 204 to relieve the pressure on the pressure plate 205 and promptly return the pressure plate 205 to its original position. Several positioning rods 206 are rotatably connected to the outer wall of the pressure plate 205. The movement of the pressure plate 205 drives the positioning rods 206 to move. The inner wall of the several positioning rods 206 is provided with a first limiting groove 208. The inner wall of the first limiting groove 208 is slidably connected to a first limiting rod 2. 09. The first limiting rod 209 changes the moving direction of the positioning rod 206, thereby causing the first limiting rod 209 to push the positioning rod 206 to rotate around the pressure plate 205. The outer wall of the positioning rod 206 is rotatably connected to the first fixing rod 207. The movement of the positioning rod 206 pushes the first fixing rod 207 to lock the locking block 210. The inner wall of the mounting block 203 is slidably connected to the locking block 210. The outer wall of the locking block 210 is fixedly connected to the second extension arc rod 211. The second extension arc rod 211... The outer wall is slidably connected to a second hollow block 212. The second extended arc rod 211 slides along the inside of the second hollow block 212, thereby pushing the locking block 210 to insert the locking block 210 into the interior of the mounting block 203. The outer wall of the first fixing rod 207 is engaged with the inner wall of the locking block 210. The outer wall of the first limiting rod 209 is fixedly connected with the inner wall of the mounting block 203. The outer wall of the second hollow block 212 is fixedly connected with the outer wall of the second connecting rod 102. The outer wall of the positioning block 101 is provided with a clamping mechanism 3.

[0030] The clamping mechanism 3 includes a second fixed rod 301. The outer wall of the second fixed rod 301 is fixedly connected to the inner wall of the positioning block 101. A groove 302 is formed on the inner wall of the second fixed rod 301. A first extension rod 303 is slidably connected to the inner wall of the groove 302. A resistance spring 304 is fixedly connected to the top outer wall of the first extension rod 303. By moving the first extension rod 303 along the groove 302 inside the second fixed rod 301, the first extension rod 303 squeezes the resistance spring 304 inside the second fixed rod 301. The elasticity of the resistance spring 304 relieves the pressure on the first extension rod 303. The elastic relief device of 4 is subjected to external pressure. The outer wall of the resistance spring 304 is fixedly connected to the inner wall of the second fixed rod 301. The outer wall of the first extension rod 303 away from the resistance spring 304 is fixedly connected to a connecting plate 305. The movement of the first extension rod 303 drives the connecting plate 305 to move, and at the same time, the connecting plate 305 drives the second limit rod 308 to move. The outer wall of the connecting plate 305 is rotatably connected to several fixed plates 306. The outer walls of the several fixed plates 306 are fixedly connected to insulating plates 307. The insulating plates 307 on the outside of the fixed plates 306 make contact with the wire in advance, thereby preventing the device from conducting electricity.

[0031] A second limiting rod 308 is rotatably connected to the outer wall of the fixed plate 306. The movement of the fixed plate 306 drives the second limiting rod 308 to move. A second limiting groove 309 is formed on the inner wall of the second limiting rod 308. A spring 311 is fixedly connected to the inner wall of the second limiting rod 308. A second extension rod 310 is fixedly connected to the outer wall of the end of the spring 311 away from the second limiting rod 308. The movement of the second limiting rod 308 causes the second extension rod 310 to move along the interior of the second limiting groove 309, simultaneously compressing the spring 311 inside the second limiting rod 308. The elasticity of the spring 311 relieves the pressure on the second extension rod 310. The outer wall of the second extension rod 310 is slidably connected to the inner wall of the second limiting groove 309, thus restricting the movement of the second extension rod 310. The movement range allows the second extension rod 310 to push the second limiting rod 308 to rotate while simultaneously pushing the fixing plate 306 closer together to clamp the wire. The outer wall of the second extension rod 310 is rotatably connected to the outer wall of the first connecting rod 1, and the outer wall of the second extension rod 310 is rotatably connected to the outer wall of the second connecting rod 102. The outer wall of the second limiting rod 308 is rotatably connected to a support rod 312. The outer wall of the support rod 312 away from the second limiting rod 308 is rotatably connected to a connecting seat 313. The rotation of the second limiting rod 308 pushes the support rod 312 to rotate around the connecting seat 313, thereby supporting the second limiting rod 308 and preventing the fixing plate 306 from shaking. The outer wall of the connecting seat 313 is fixedly connected to the outer wall of the positioning block 101.

[0032] One specific application of this embodiment is:

[0033] When the staff needs to use the equipment, the entire device is placed in the required installation position, with the power cord on the outside of the connecting plate 305. Simultaneously, the device is continuously pressed down, causing the connecting plate 305 to move along the groove 302 inside the second fixed rod 301. This shortens the exposed length of the first extension rod 303, causing the connecting plate 305 to move the fixed plate 306. The movement of the fixed plate 306 pushes the second limiting rod 308, which in turn causes the second limiting rod 308 to rotate the second extension rod 310 around the connected first connecting rod 1 and second connecting rod 102. The rotation of the second extension rod 310 then moves along the groove 302 inside the second fixed rod 301. The second limiting groove 309 inside the second limiting rod 308 moves, causing the second extension rod 310 to push the second limiting rod 308 to rotate, while simultaneously causing the fixing plate 306 to rotate around the connecting plate 305. This brings the two fixing plates 306 closer together, clamping the wire while the insulating plate 307 separates the fixing plate 306 from the wire. As the second extension rod 310 moves along the inside of the second limiting rod 308, it compresses the spring 311 inside the second limiting rod 308. The elasticity of the spring 311 increases the pressure of the second limiting rod 308 on the fixing plate 306, thus securing the wire more firmly. During the rotation of the second limiting rod 308... This will cause the support rod 312 to rotate around the connecting seat 313, thereby allowing the support rod 312 to support the second limiting rod 308, thus stabilizing the support force of the second limiting rod 308 on the fixed plate 306. Then, the mounting block 203 and the locking block 210 are pulled simultaneously, causing the first extended arc rod 202 and the second extended arc rod 211 to move respectively, and the first hollow block 201 and the second hollow block 212 are used to limit their movement range. Then, the locking block 210 is inserted into the interior of the mounting block 203, and the locking block 210 pushes the pressure plate 205 inside the mounting block 203 to move while squeezing the pressure spring 204. The elasticity of the pressure spring 204 can be used to easily compress the pressure plate 204. When plate 205 springs back to its original position, the movement of pressure plate 205 will push positioning rod 206 to move and simultaneously drive first fixing rod 207 to move. The movement of positioning rod 206 will cause first limiting rod 209 to move along the inside of first limiting groove 208, thereby changing the range of movement of positioning rod 206. This will cause first limiting rod 209 to push positioning rod 206 to rotate around pressure plate 205 and push first fixing rod 207 to insert into the inside of locking block 210, and then lock locking block 210, thereby fixing the movement of first extension arc rod 202 and second extension arc rod 211. At this time, the device will be fixed to the wire.
