Description

Technical Field

[0001] The utility model relates to the technical field of power distribution overhead lines, in particular to an auxiliary installation and disassembly device for CT power taking equipment on overhead lines. Background Art

[0002] Overhead lines primarily refer to overhead lines, installed above the ground. They use insulators to secure power conductors to towers erected on the ground to transmit electricity. They are easy to install and maintain, and relatively inexpensive. However, they are susceptible to weather and environmental factors (such as strong winds, lightning strikes, pollution, ice, and snow), which can cause failures. Overhead line failures can affect the normal flow of electricity, so fault monitoring is often performed on distribution lines to improve power supply reliability.

[0003] CT power supply equipment, which inspects, detects, and monitors circuit faults, must be installed on overhead distribution lines. These lines must be powered on to install the CT power supply equipment. Since the installation and removal of CT power supply equipment is a large, outdoor pole-mounted operation, ensuring safe, reliable, and efficient installation is crucial. Existing CT power supply equipment is cumbersome, difficult to operate, unreliable, and dangerous to install.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0037] The following is combined with Figure 1-5 The utility model is further described.

[0038] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0039] Reference Figures 1 to 5, an auxiliary installation and disassembly device for CT power taking equipment on an overhead line, used for installing or disassembling the CT power taking equipment 7 on the overhead line, such as installing the CT power taking equipment 7 on the cable 6 of the overhead line or disassembling the CT power taking equipment 7 from the cable 6 of the overhead line. The auxiliary installation and disassembly device for CT power taking equipment on the overhead line includes a mounting shell 1, a wire fixing component 2 and a hook component 3, wherein the mounting shell 1 is used to carry the CT power taking equipment 7 to be installed, and the mounting shell 1 is a hollow shell structure, that is, the mounting shell 1 has an internal cavity, and one side of the mounting shell 1 is open, and the CT power taking equipment 7 can be movably installed in the internal cavity from the opening; the wire fixing component 2 is used to clamp the cable 6, and when the wire fixing component 2 is in a closed state, it can clamp the cable 6, so that the CT power taking equipment 7 can be installed and fixed on the cable 6; the hook component 3 is used to hook the wire fixing component 2, so that the wire fixing component 2 is in an open state, so that the CT power taking equipment 7 can be installed on the cable 6.

[0040] Reference Figure 3 and Figure 4 The wire fixing assembly 2 includes an elastic wire clamp 21 and a power taking ring 22. The elastic wire clamp 21 is rotatably arranged on the CT power taking device 7. The elastic wire clamp 21 is used to clamp the cable 6 inside the power taking ring 22. Specifically, the elastic wire clamp 21 can be a torsion spring structure, and there are two elastic wire clamps 21. The two elastic wire clamps 21 are arranged on both sides of the power taking ring 22. The two elastic wire clamps 21 cooperate to clamp the cable 6 inside the power taking ring 22. One end of the power taking ring 22 is rotatably connected to the CT power taking device 7. The elastic wire clamp 21 is in a closed state to clamp the cable 6, and the power taking ring 22 rotates to the CT power taking device 7 and is also in a closed state. The power taking ring 22 is used to draw power from the cable 6, that is, the power taking ring 22 draws power from the cable 6 through electromagnetic induction to supply power to the CT power taking device 7. Since the CT power taking ring 22 is a prior art, the specific structure and working principle of the power taking ring 22 will not be described here.

[0041] Reference Figure 3 and Figure 4The hook assembly 3 includes a first hook 31 and a second hook 32. The first hook 31 is arranged corresponding to the elastic wire clamp 21, and the second hook 32 is arranged corresponding to the power-taking ring 22. The first hook 31 is used to hook and fix the elastic wire clamp 21, and the second hook 32 is used to hook and fix the power-taking ring 22, so that the wire fixing assembly 2 is in an open state. Specifically, a mounting frame 11 is fixedly connected to the opening side of the mounting shell 1, and a first mounting shaft 111 is fixedly connected to the mounting frame 11. The first hook 31 is rotatably connected to the first mounting shaft 111, and a second mounting shaft 112 is fixedly connected to the mounting frame 11. The second hook 32 is rotatably connected to the second mounting shaft 112. In this embodiment, each elastic wire clamp 21 is correspondingly provided with two first hooks 31, and the two first hooks 31 are symmetrically arranged at both ends of the elastic wire clamp 21. Each elastic wire clamp 21 is correspondingly provided with two first hooks 31, which is conducive to ensuring the stability of the elastic wire clamp 21 when it is in an open state. When the first hooks 31 are hooked on the corresponding elastic wire clips 21 and the second hooks 32 are hooked on the rotating ends of the power ring 22 , the wire fixing assembly 2 is in an open state, and the device can be installed on the cable 6 at this time.

[0042] Reference Figure 3 and Figure 4The mounting housing 1 is also provided with a trigger assembly, which is used to trigger the cable fixing assembly 2 to enter a closed state to clamp the cable 6. The trigger assembly includes a sheet metal frame 4, a first drive shaft 41, a second drive shaft 42, and an elastic member 44. The sheet metal frame 4 is movably mounted on the mounting housing 1. Specifically, the mounting housing 1 is provided with a mounting slot 12. The sheet metal frame 4 floats up and down along a guide shaft 43 and is mounted within the mounting slot 12. The elastic member 44 is provided on the side of the sheet metal frame 4 facing the bottom wall of the mounting slot 12. The elastic member 44 is used to drive the sheet metal frame 4 to return to its initial position. When the device is installed on the cable 6, the lifting device causes the cable 6 to press down on the sheet metal frame 4. At this time, the drive shaft drives the hook assembly 3 to disengage from the cable fixing assembly 2. The driving shaft includes a first driving shaft 41 and a second driving shaft 42. The first driving shaft 41 is fixedly connected to the sheet metal frame 4, and the first driving shaft 41 is correspondingly arranged to the first hook 31. When the cable 6 presses down the sheet metal frame 4 and drives the sheet metal frame 4 to slide downward in the mounting groove 12, the first driving shaft 41 moves downward with the sheet metal frame 4, and presses down the end of the first hook 31 during the downward movement, so that the first hook 31 rotates around the first mounting axis 111 until the hook end of the first hook 31 is separated from the elastic wire clamp 21; the second driving shaft 42 is fixedly connected to the mounting frame 11, and the second driving shaft 42 is correspondingly arranged to the second hook 32. Similarly to the first driving shaft 41, the sheet metal frame 4 drives the second driving shaft 42 to move downward, so that the second driving shaft 42 drives the second hook 32 to flip, thereby realizing the separation of the second hook 32 from the power ring 22. In this embodiment, the sheet metal frame 4 is annular and surrounds the CT power supply device 7. The elastic member 44 is a first spring. A plurality of guide shafts 43 are fixedly mounted on the sheet metal frame 4. The guide shafts 43 correspond to the guide holes of the mounting housing 1, and the sheet metal frame 4 floats up and down along the guide shafts 43. The first spring is provided in a one-to-one correspondence with the guide shafts 43. The first spring is sleeved on the guide shafts 43, with one end of the first spring abutting the side of the sheet metal frame 4 facing the mounting slot 12, and the other end abutting the bottom wall of the mounting slot 12. When the sheet metal frame 4 is subjected to pressure from the cable 6 and slides downward along the guide shafts 43 in the mounting slot 12, the elastic member 44 is elastically compressed. When the sheet metal frame 4 is free from the pressure of the cable 6, the elastic member 44 drives the sheet metal frame 4 to return to its original position.

[0043] A first torsion spring 311 is also sleeved on the first mounting shaft 111. One torsion arm of the first torsion spring 311 abuts against the mounting bracket 11, and the other torsion arm abuts against the first hook 31. When the first hook 31 is hooked on the elastic wire clamp 21, the first torsion spring 311 is elastically compressed. When the first drive shaft 41 drives the first hook 31 to disengage from the elastic wire clamp 21, the first torsion spring 311 is elastically released, driving the first hook 31 to rotate relative to the first mounting shaft 111 in a direction away from the elastic wire clamp 21, thereby driving the first hook 31 to return to its initial position. A second torsion spring 321 is sleeved on the second mounting shaft 112. One torsion arm of the second torsion spring 321 abuts against the mounting bracket 11, and the other torsion arm abuts against the second hook 32. When the second hook 32 is hooked on the rotating end of the power extraction ring 22, the second torsion spring 321 is elastically compressed. When the second drive shaft 42 drives the second hook 32 to disengage from the power extraction ring 22, the second torsion spring 321 drives the second hook 32 to return to its initial position. When the hook assembly 3 is separated from the wire fixing assembly 2 , the elastic wire clamp 21 clamps the cable 6 , and the power taking ring 22 is also in a closed state. At this time, the CT power taking device 7 and the cable 6 are installed and fixed.

[0044] The mounting frame 11 is also provided with a first limiting member 13 and a second limiting member 14, which are respectively used to limit the movable range of the first hook 31 and the second hook 32. The first limiting member 13 is integrally formed with the mounting frame 11, and the first limiting member 13 and the first hook 31 are arranged one-to-one. The first torsion spring 311 elastically releases and drives the first hook 31 to rotate on the first mounting shaft 111 until it is reset, and the end of the first hook 31 abuts the first limiting member 13. In this embodiment, the first limiting member 13 is integrally formed with the mounting frame 11; the second limiting member 14 is fixedly connected to the mounting frame 11, and the second limiting member 14 is corresponding to the second hook 32. The second torsion spring 321 elastically releases and drives the second hook 32 to rotate on the second mounting shaft 112 until it is reset, and the end of the second hook 32 abuts the second limiting member 14. In this embodiment, the first limiting member 13 is integrally formed with the mounting frame 11, and the second limiting member 14 is a limiting shaft fixedly connected to the mounting frame 11. The first limiting member 13 and the second limiting member 14 are provided to limit the rotation range of the first hook 31 and the second hook 32, effectively reducing the possibility of excessive rotation of the first hook 31 and the second hook 32 driven by the first torsion spring 311 and the second torsion spring 321, thereby affecting the installation of the equipment, and helping to ensure the stability and reliability of the use process.

[0045] It is easy to understand that when the CT power supply device 7 needs to be installed on the cable 6, the operator first installs the CT power supply device 7 to be installed into the internal cavity of the installation shell 1, opens the power supply ring 22, and hooks the second hook 32 on the rotating end of the power supply ring 22, so that the power supply ring 22 is in an open state; then the elastic wire clamp 21 is opened, and the elastic wire clamp 21 is hooked and fixed by the first hook 31, so that the elastic wire clamp 21 remains in an open state. At this time, the installation shell 1 together with the CT power supply device 7 is lifted to the location of the cable, and the cable is continued to be lifted until the elastic wire clamp 21 and the power supply ring 22 are separated from the first hook 31 and the second hook 32 respectively, so that the wire fixing component 2 is in a closed state. Under the elastic force of the elastic wire clamp 21, the cable 6 can be clamped, so that the CT power supply device 7 is installed and fixed on the cable 6, and the hooking component is reset under the drive of the first torsion spring 311 and the second torsion spring 321.

[0046] Reference Figures 3 to 5 The auxiliary installation and removal device for CT power supply equipment on overhead lines also includes a limit assembly 5 and a link rod (not shown). The limit assembly 5 is used to clamp and secure the CT power supply equipment 7 to the mounting housing 1, allowing the CT power supply equipment 7 to be removed from the overhead line; the link rod is used to assist in supporting the entire device. The limit assembly 5 includes a self-locking pin 51, a rotating buckle 52, and a limit torsion spring 53. The rotating buckle 52 is used to abut and clamp the CT power supply equipment 7, thereby securing the mounting housing 1 to the CT power supply equipment 7. Specifically, a limit assembly bracket 15 is fixedly provided in the mounting shell 1, and a rotating buckle 52 is provided in the limit assembly bracket 15 and rotates. The limit assembly bracket 15 is fixedly connected to the limit mounting shaft 18, and the rotating buckle 52 is rotatably connected to the limit mounting shaft 18. The limit torsion spring 53 is sleeved on the limit mounting shaft 18, and one side torsion arm of the limit torsion spring 53 abuts against the limit assembly bracket 15, and the other side torsion arm abuts against the rotating buckle 52. When the limit torsion spring 53 is elastically released, the limit torsion spring 53 drives the rotating buckle 52 to rotate toward the direction close to the internal cavity of the mounting shell 1.

[0047] When the locking pin 51 is in the locked state, the locking pin 51 is locked and the locking pin 51 is in the locked state. When the self-locking pin 51 is inserted into the limiting hole 192, the limiting torsion spring 53 is elastically compressed. At this time, the limiting assembly 5 has no limiting effect on the CT power supply device 7 installed in the installation shell 1, that is, the CT power supply device 7 is movable in the installation shell 1, that is, the CT power supply device 7 can be installed in or removed from the installation shell 1. When the self-locking pin 51 is pressed so that the large diameter end of the self-locking pin 51 is released from the restriction of the limiting plate 19, the limiting torsion spring 53 drives the rotating buckle 52 to rotate toward the direction close to the internal cavity of the installation shell 1. Correspondingly, a flange boss 71 capable of abutting against the rotating buckle 52 is provided at the corresponding position of the CT power supply device 7. When the limiting torsion spring 53 is elastically released, the rotating buckle 52 can abut against the corresponding flange boss 71, thereby clamping and fixing the CT power supply device 7. In this embodiment, a group of limit components 5 are respectively provided on the opposite sides of the mounting shell 1 to ensure the reliability of holding the CT power taking device 7. When the limit components 5 hold and fix the CT power taking device 7, the CT power taking device 7 can be removed from the cable 6 by pulling the link rod downward.

[0048] The linker rod is removably mounted on the mounting housing 1. Specifically, a threaded hole 16 is defined at the bottom of the mounting housing 1, and the end of the linker rod is provided with a mating external thread. The linker rod is threadedly connected to the threaded hole 16. The linker rod is an insulating rod. Its installation facilitates the operator's ability to raise the mounting housing 1 to the height of the cable 6, facilitating installation of the device. In practice, the linker rod's length can be adjusted according to actual needs. The threaded connection between the linker rod and the mounting housing 1 facilitates installation and removal. Furthermore, the insulating nature of the linker rod keeps the operator away from overhead lines carrying high voltage, preventing the operator from direct contact with the cable 6 and the risk of electric shock, effectively improving the safety of operations on overhead lines.

[0049] As is easy to understand, during installation, the entire device can be lifted using a link rod. When the CT power supply device 7 on the cable 6 needs to be removed, the self-locking pins 51 on both sides are first pressed to release the self-locking pins 51 from the limit plate 19. The limit torsion spring 53 drives the rotating buckle 52 to rotate toward the internal cavity of the installation housing 1. Install the Link rod on the mounting shell 1, and lift the mounting shell 1 to the CT power taking device 7 that needs to be removed, and let the CT power taking device 7 enter the internal cavity of the mounting shell 1. The flange boss 71 of the CT power taking device 7 presses the rotating buckle 52 to rotate toward the outside of the mounting shell 1. When the CT power taking device 7 completely enters the position in the mounting shell 1, the limiting torsion spring 53 drives the rotating buckle 52 to move toward the inside of the mounting shell 1 and clamps it on the CT power taking device 7. The limiting component 5 clamps and fixes the CT power taking device 7 and the mounting shell 1. At this time, pull down the Link rod, and the elastic wire clamp 21 begins to separate from the cable 6 under the action of tension, and the power taking ring 22 also begins to be in an open state. At this time, rotate the Link rod while pulling down to make the wire fixing component 2 and the cable 6 misaligned until the CT power taking device 7 is separated from the cable 6, that is, the disassembly of the CT power taking device 7 is completed. The operation is simple, the disassembly and assembly efficiency is high, and the safety factor is high.
