Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary replacement of electric power engineering, in particular to a replacement mechanism and a tension composite insulator adjustment device. Background Art

[0002] Strain composite insulators are insulating devices used in power lines. Made primarily of composite materials, they offer excellent mechanical strength and electrical insulation. They are commonly used in high-voltage and ultra-high-voltage transmission lines to prevent current leakage and ensure safe power transmission. They are also designed to withstand external loads such as the weight of the conductors and wind, ensuring conductor stability. Compared to traditional ceramic insulators, strain composite insulators are lighter, perform better under ultraviolet light and climate change, and have a longer service life.

[0003] In practical power generation, composite insulators are widely used in overhead lines due to their small size and light weight. However, currently, replacing 110kV composite tension insulators can only be done using equipotential bonding, which requires a power outage during the installation process, resulting in power outages and user disruptions. This operation is costly and difficult, making it difficult to meet the existing requirement for non-stop insulator replacement. Therefore, a replacement mechanism and a composite tension insulator adjustment device are proposed. Utility Model Content

[0013] As a preferred solution of the display structure of the present invention, one end of the upper spur rack away from the gear is fixedly connected to a clamping block, and the clamping block fits against the side surface of the rotating block.

[0037] Example 1

[0038] Reference Figure 1-Figure 3 , which is the first embodiment of the present utility model, provides a replacement mechanism, which clamps the pins through the clamp 107 and installs the pins to fix the insulator string, making it easy to replace the insulator string.

[0039] The tension composite insulator replacement mechanism includes a fixing assembly 100 .

[0040] Specifically, the fixing assembly 100 includes a fixing plate 101, and the fixing plate 101 is two symmetrical panels. The sliding shaft 102 is slidably connected inside the two fixing plates 101. The inner side of the fixing plate 101 is located below the sliding shaft 102 and is rotatably connected to a rotating shaft 103. A first connecting rod 104 is rotatably connected below the rotating shaft 103. A second connecting rod 105 is rotatably connected above the rotating shaft 103. The end of the second connecting rod 105 away from the first connecting rod 104 is rotatably connected to a horizontal cross plate 106. The surface of the cross plate 106 is slidably connected to a clamp 107, and the middle part of the clamp 107 is rotatably connected to a rotating block 108.

[0041] Furthermore, vertical arc-shaped grooves 101a are formed on the inner sides of the two fixed plates 101 at positions corresponding to the sliding shaft 102. The sliding shaft 102 moves along the vertical arc-shaped grooves 101a. The maximum angle between the first connecting rod 104 and the second connecting rod 105 is an obtuse angle. A limit bar 104a is fixedly connected to the side of the first connecting rod 104. The limit bar 104a can limit the angle between the first connecting rod 104 and the second connecting rod 105.

[0042] Two symmetrical horizontal arc-shaped grooves 106a are provided on the top surface of the horizontal plate 106;

[0043] The clamp 107 includes a left clamp 107a and a right clamp 107b, which are hingedly connected to each other and rotatably connected to the surface of the rotating block 108;

[0044] The left clamp 107a and the right clamp 107b slide towards each other inside the two horizontal arc-shaped grooves 106a respectively.

[0045] Preferably, the bottom of the inner side of the two fixed plates 101 is slidably connected with a lower straight rack 109, and the end of the lower straight rack 109 away from the horizontal plate 106 is meshed with a gear 110, and the top of the gear 110 is meshed with an upper straight rack 111, and the upper straight rack 111 is slidably connected between the two fixed plates 101, and the side of the lower straight rack 109 close to the limit bar 104a is fixedly connected to a push plate 109a, and the vertical height of the push plate 109a is higher than the maximum vertical height of the limit bar 104a, and the end of the upper straight rack 111 away from the gear 110 is fixedly connected with a clamping block 111a, and the clamping block 111a can clamp and fix the side of the rotating block 108.

[0046] The clamps 107 are all made of insulating materials. When in use, the staff can pinch the clamp 107 to clamp the end of the clamp 107 to the pin away from the end of the horizontal plate 106, and then press the clamp 107 downward. The clamp 107 rotates around the rotating block 108. At this time, the first connecting rod 104a contacts the push plate 109a, and the push plate 109a slides toward the gear 110, while driving the upper straight rack 111 to slide toward the gear 110. The pin can be pulled out through the above operation. If the pin needs to be installed, the staff clamps the clamp 107. Clamp the pin and then lift the clamp 107 upward. At this time, the clamp 107 rotates around the rotating block 108, and the angle between the first connecting rod 104 and the second connecting rod 105 increases. The lower straight rack 109 slides in the direction away from the gear 110, thereby driving the upper straight rack 111 and the clamping block 111a to slide in the direction close to the rotating block 108 until the rotating block 108 contacts the clamping block 111a, and the pin is fixed. At this time, after the pin enters the pin hole, the pin can be inserted and pulled out when the entire circuit is charged, which is convenient for fixing the insulator strings.

[0047] Example 2

[0048] Reference Figure 4-Figure 7 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides an adjustment device for a tension composite insulator. By rotating the wrench 210, the length of the screw 206 inside the sleeve 205 is adjusted, and then the distance between the two pins is adjusted, which facilitates the replacement of the insulator string.

[0049] The adjusting device for a tension composite insulator further includes an adjusting mechanism 200 .

[0050] Specifically, the adjustment mechanism 200 includes a fixed block 201, which includes a left fixed block 201a. Two parallel glass connecting plates 202 are fixedly connected to the inner side of the left fixed block 201a. The end of the glass connecting plate 202 away from the left fixed block 201a is fixedly connected to the right fixed block 201c. An inner fixed block 201b is fixedly connected between the left fixed block 201a and the right fixed block 201c and located on the two glass connecting plates 202. The bottom surface of the rotating block 108 is rotatably connected to the top surface of the inner fixed block 201b. A right limiting groove 203 is fixedly connected to the end of the right fixed block 201c away from the inner fixed block 201b. The right limiting groove 203 is plugged with a live pin 204. The end of the left fixed block 201a away from the inner fixed block 201b is fixedly connected to the sleeve 205. The fixed plate 101 is fixedly connected to the top surface of the glass connecting plate 202.

[0051] Preferably, the interior of the sleeve 205 is provided with an internal thread, and the interior of the sleeve 205 is provided with a rotating screw 206, and the screw 206 has the same size as the thread inside the sleeve 205. The end of the screw 206 away from the sleeve 205 is fixedly connected to a rotating gear shaft 207, and the end of the rotating gear shaft 207 away from the screw 206 is fixedly connected to a right limit groove 208, and a non-electric pin 209 is inserted at the top of the right limit groove 208, and a wrench 210 is provided on the periphery of the rotating gear shaft 207.

[0052] Furthermore, a circular groove 210a is provided in the middle of the inner side of the wrench 210, and a special-shaped groove 210b is provided on the upper part of the inner side of the wrench 210. The inner part of the circular groove 210a is rotatably connected to a conversion block 211. An inner groove 211a is provided on the inner side of the conversion block 211. A handle 211b is fixedly connected to the side of the conversion block 211. A spring 212 is fixedly connected to the bottom of the inner groove 211a. The end of the spring 212 away from the conversion block 211 is fixedly connected to the handle 211b. A toggle rod 213 is connected, and the side of the toggle rod 213 close to the circular groove 210a is slidably connected to the inside of the inner groove 211a. The end of the toggle rod 213 away from the spring 212 is clamped with a gear ring 214. The end of the gear ring 214 away from the toggle rod 213 is provided with teeth of the same size as the rotating gear shaft 207. The gear ring 214 is meshed with the rotating gear shaft 207, and the end of the gear ring 214 away from the toggle rod 213 conflicts with the special-shaped groove 210b.

[0053] The staff rotates the handle 211b to synchronously rotate the conversion block 211, so that the toggle rod 213 inside the conversion block 211 is clamped on one end of the gear ring 214. At this time, the other end of the gear ring 214 contacts the special-shaped groove 210b. Then, when the staff moves the wrench 210 upward, the gear ring 214 locks the rotating gear shaft 207. When the staff holds the wrench 210 and pushes it downward, the gear ring 214 engages and rotates with the rotating gear shaft 207. At this time, the toggle rod 213 slides up and down inside the inner groove 211a under the traction of the spring 212, and then when the staff moves the wrench 210 upward, the gear ring 214 is locked to the rotating gear shaft 207. At 0, the rotating gear shaft 207 is driven to rotate clockwise. Since the rotating gear shaft 207 is fixedly connected to the screw 206, and the screw 206 is rotatably connected to the inside of the sleeve 205, the screw 206 is extended inside the sleeve 205. If the length of the screw 206 inside the sleeve 205 needs to be shortened, the handle 211b is rotated to make the toggle rod 213 clamped on the other end of the gear ring 214. The above operation can adjust the distance between the non-electric pin 209 and the electrified pin 204. The distance between the insulator strings changes, making the replacement of the insulator strings more convenient and efficient.

[0054] Example 3

[0055] Reference Figure 1-8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a replacement mechanism and a tension composite insulator adjustment device. Combining the working principles of the first and second embodiments:

[0056] When in use, the staff first measures the actual length of the two triangular connecting plates between the insulator strings, and then pushes the wrench 210 upward to lock the gear ring 214 with the rotating gear shaft 207. At this time, the screw 206 extends inside the sleeve 205. After adjusting to the appropriate length, the staff places the left limit slot 208 on the triangular connecting plate to align the hole on the triangular connecting plate with the left limit slot 208. Then, the non-electric pin 209 is inserted into the triangular connecting plate on the conductor side. The staff pinches the clamp 107 to clamp the live pin 204 through the clamp 107, and then lifts the clamp 107 upward to make the live pin The pin 204 enters the right limit slot 203 and the hole of the triangular connecting plate. During this process, the angle between the first connecting rod 104 and the second connecting rod 105 increases, and the lower straight rack 109 slides in the direction away from the gear 110, thereby driving the clamping block 111a at the end of the upper straight rack 111 to slide in the direction close to the rotating block 108. The rotating block 108 contacts the clamping block 111a, and the live pin 204 is fixed. At this time, the distance between the two insulator strings is shortened, and the staff uses the external insulating clamp to pull out and replace the M pin fixed on the insulator string and the triangular connecting plate to complete the live replacement of the insulator string.
