Description

Technical Field

[0001] This invention relates to the field of power line auxiliary equipment technology, and in particular to a device for quickly resetting and fixing energized conductors that have become detached. Background Technology

[0002] In the power system, most transmission lines are exposed to the natural environment for a long time and are extremely susceptible to severe weather such as strong winds and snow. In windy weather, the conductors may swing violently or even break off, which seriously affects the stable operation of the power grid.

[0003] In existing technologies, to reduce the occurrence of power accidents and quickly restore operation, power workers employ two methods for power outage repair and live-line repair: power outage repair involves completely shutting down the line and then having workers climb poles to use traditional binding methods to bind the conductors and insulators. This method requires a power outage, involves many steps, and takes a long time, severely impacting users' normal power supply. Live-line repair, on the other hand, involves resetting the conductors without shutting down the power line. It is widely used because it does not affect normal power supply compared to power outage repair. The insulated wire rake used in this repair operation has a hook-shaped structure or a groove at the front end of its head, designed to facilitate lifting, resetting, and limiting the installation of detached conductors. However, in practical applications, especially in windy weather and harsh working environments, conductors often exhibit dynamic swaying. During live-line work and after resetting the conductors, the conductors may experience insufficient limiting capacity due to dynamic swaying, leading to secondary detachment or displacement. This undoubtedly increases the difficulty and risk of the operation, and in severe cases, may threaten the personal safety of the workers. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the situation where the operating device used in the live working process has insufficient ability to limit the conductor, resulting in the secondary detachment or displacement of the conductor, and to provide a live working quick reset and fixing device for detached conductors that enhances the limiting ability of the conductor during the operation.

[0005] To solve the above-mentioned technical problems, the present invention provides a device for quick reset and fixing of detached wires under live conditions, comprising: A wire derailment limiting bracket includes: a support arm, on which at least one set of anti-derailment clamps are fixed, the anti-derailment clamps restricting the movement space of the wire; A clamp fixing base, installed below the support arm, is used to connect insulated wire cylinders. It includes: a flexible binding element, specifically a strip or wire-shaped pre-twisted wire; a clamp body, composed of an arc-shaped part and a mounting part, wherein the end of the arc-shaped part has a through hole for mounting the flexible binding element; a winding structure, which is rotatably mounted on the mounting part for winding and tightening the flexible binding element; and a limiting element, installed on the mounting part, for limiting the winding structure. The connector is used to connect the support arm and the winding structure, and transmits the power of the winding structure to the support arm when it winds and tightens the flexible binding material. When the winding structure winds and tightens the flexible binding material, it drives the support arm to move down, so that the anti-derailment clamp presses against the wire and restricts the wire's movement space.

[0006] In one embodiment of the present invention, the connector is a columnar structure with an externally threaded outer wall, and is divided into the following sections from bottom to top: An adjusting connection part is used to connect the support arm. The support arm is provided with a threaded through hole. The external thread structure of the adjusting connection part is threadedly engaged with the threaded through hole. A limit bolt is installed on the support arm corresponding to the position of the threaded through hole. The lower connecting part is fixedly connected to the winding structure and rotates with it.

[0007] In one embodiment of the present invention, the winding structure includes: The connecting sleeve tapers in a stepped manner from top to bottom along its axial direction, and is divided into: The upper connecting part has an internal thread structure on its inner side wall, which is used to connect and fix the lower connecting part. The lower end has a through-part that passes through the mounting part from top to bottom and is rotatably connected to it; The winding sleeve has an internally threaded inner wall and a limiting ring on its outer wall. The winding sleeves on the upper and lower sides of the limiting ring are respectively: The upper through-part extends from bottom to top through the mounting part and is fixed in place with the lower through-part, and is also fitted with a limiting ring to limit the lower through-part. The lower winding section has a through groove for installing and connecting flexible binding components; Fasteners are fixedly installed at the lower winding section opening and are used to tighten the flexible binding components.

[0008] In one embodiment of the present invention, after the wire is placed in the groove of the insulating wire bottle, the vertical movement distance of the wire in the anti-detachment clamp is h, the tightening length reserved by the flexible binding member is l, the pitch of the external thread structure of the connector is p, the circumference of the outer wall of the lower winding part is c, and the movement distance of the support arm relative to the connector is h1 during the rotation and tightening of the flexible binding member. h1 = l·p / c, h1 > h.

[0009] In one embodiment of the present invention, the outer wall of the lower through portion is an external thread structure, the inner thread structure of the inner wall of the upper through portion is threadedly engaged with the external thread structure of the outer wall of the lower through portion, and the outer wall of the upper through portion is uniformly provided with a limiting groove along its circumferential direction. The limiting groove and the limiting member cooperate to limit the rotation of the winding structure. The limiting member is a spring limiting structure.

[0010] In one embodiment of the present invention, each anti-detachment clip includes: The conductor receiving structure is made of insulating material and is installed and fixed on the upper base surface at the end of the support arm. The upper end of the conductor receiving structure is open. At least one limit locking assembly is rotatably mounted on the open end of the wire receiving structure to close that end.

[0011] In one embodiment of the present invention, the limiting lock assembly includes: The lower pressure plate is rotatably mounted on the opening end of the wire receiving structure; The elastic reset component is used to connect the lower pressure plate and the wire housing structure, providing the power for the lower pressure plate to reset.

[0012] In one embodiment of the present invention, the lower pressure plate is an integrally formed right-angle structure, comprising: The rotating connection part is rotatably connected to the open end of the wire receiving structure; The sealing part, which rotates with the rotating connecting part, is used to open and close the opening end of the wire receiving structure; The limiting reinforcement part, which cooperates with the wire receiving structure, is used to limit the rotation of the rotary connection part; The connection between the rotating part and the limiting reinforcement part is the fracture zone, which breaks after exceeding the stress threshold.

[0013] In one embodiment of the present invention, it further includes: The insulating rod is made of insulating material and has a connector at its end; The operating head is detachably installed at the end of the insulating rod and is used to tighten the limit bolts; The operating head is a corner device structure, with a first connector and a second connector respectively. The surfaces of the first connector and the second connector are adjacent and form a right angle.

[0014] The technical solution of the present invention has the following advantages compared with the prior art: Once the conductor enters the anti-detachment clamp, the power worker lifts the conductor to the upper slot of the insulated insulator to achieve a live-line reset, detaching the conductor. During this process, the anti-detachment clamp restricts the conductor's movement, preventing significant swinging. This works in conjunction with the tightening action of the winding structure's flexible binding element. Furthermore, a power transmission mechanism is introduced: as the winding structure (such as a winch or tightening wheel) rotates, it continuously tightens the flexible binding element, securely fastening the clamp to the insulated insulator. Simultaneously, the rotational power of the winding structure is not consumed in isolation but transmitted through a separate connector to the upper support arm, allowing it to move downwards. Since the conductor has entered the anti-detachment clamp, the winding... As the rotating structure moves the support arm downwards, it also moves the anti-derailment clamp downwards. At this time, the wire inside the anti-derailment clamp is supported by the upper groove of the insulating cylinder, causing the anti-derailment clamp to change from supporting the wire to pressing and limiting the wire. The invention also includes a limiting component that can limit the tightness of the winding structure. While the winding structure tightens the flexible coil and is fixed by the limiting component, the anti-derailment clamp applies downward pressure to the wires at both ends of the insulating cylinder. This, combined with the limiting component, limits the winding structure, ensuring that the wire is pressed tightly into the upper groove of the insulating cylinder by the anti-derailment clamp. This effectively prevents secondary detachment and displacement caused by insufficient limiting capability of the device used by power workers during operation. In summary, this invention features an integrated mechanical structure and an ingenious mechanical linkage design that integrates the two functions of wire binding and spatial limiting, dynamically linking the wire binding and tightening process with its spatial limiting process, thereby achieving synchronous operation of installation and reinforcement limiting.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0018] Reference Figure 1 , 9 As shown in Figures 1 and 10, a quick-reset and fixing device for live wire detachment according to the present invention includes: The derailment limit bracket 1 includes: The support arm 11 is fixed with at least one set of anti-derailment clamps 12. The anti-derailment clamps restrict the movement space of the conductor. Here, the support arm 11 has an arc-shaped structure. The anti-derailment clamps 12 are fixed on the base surface at both ends of the support arm 11 and are located on both sides of the insulated wire bottle to stabilize the conductor. It should be noted that if there are two or three sets of anti-derailment clamps 12, the structure of the support arm 11 can also be other structures, as long as the anti-derailment clamps 12 are symmetrically distributed on both sides of the insulated wire bottle after installation to stabilize the conductor above it. Clamp fixing base 2, installed below the support arm 11, is used to connect the insulated wire bottle, and includes: Flexible binding element 21, specifically a strip or wire pre-twisted wire, is selected according to the structure of the insulated wire cylinder; The clamp body 22 is composed of an arc-shaped part 221 and an installation part 222. The arc-shaped part 221 has a through hole 2211 at its end for the installation of the flexible binding member 21. The structure of the through hole 2211 is compatible with the structure of the flexible binding member 21. The winding structure 23 is rotatably mounted on the mounting part 222 for winding and tightening the flexible strapping member 21; The limiting member 24 is installed on the mounting part 222 and is used to limit the winding structure 23; The connector 3 is used to connect the support arm 11 and the winding structure 23, and transmits the power of the winding structure 23 to the support arm 11 to tighten the flexible binding member 21. When the winding structure 23 tightens the flexible binding member 21, it drives the support arm 11 to move down, so that the anti-detachment clamp 12 presses against the wire and restricts the movement space of the wire. This invention is applied to the process of quickly resetting and fixing a conductor when it detaches from an insulated insulator without interrupting power. Using the device of this invention, the electrician inserts the conductor into the anti-detachment clamp 12, which lifts the conductor to the upper groove of the insulator, providing support. The tightening ring formed by the connection of the flexible binding member 21 and the winding structure 23 is then placed on the insulator. At this time, the anti-detachment clamp 12 restricts the conductor's movement, preventing large swings, while simultaneously tightening the flexible binding with the winding structure 23. The action of component 21 is coordinated, that is, the tightening action of the connecting component 3 and the winding structure 23 drives the support arm 11 to move down, so that the anti-derailment clamp 12 moves down at the same time. At this time, the wire inside the anti-derailment clamp 12 is supported by the upper wire groove of the insulating wire bottle. The anti-derailment clamp 12 changes from the state of supporting the wire to the state of pressing down and limiting the wire. While the winding structure 23 tightens the flexible coil and is limited and fixed by the limiting component 24, the wires at both ends of the insulating wire bottle of the anti-derailment clamp 12 apply downward pressure. The limiting component 24 limits the winding structure 23, so that the wire is pressed by the anti-derailment clamp 12 into the upper wire groove of the insulating wire bottle. The core of the technical solution of this invention lies in the dynamic correlation between the binding and fastening process of the wire and its spatial limiting process through an integrated mechanical structure, so as to achieve synchronous operation and dual protection. The device first manages the position of the wire through a wire-detachment limiting frame 1. The anti-detachment clamp 12 fixed on its support arm 11 does not adopt a rigid locking design, but restricts the movement space of the wire. This allows the wire to have a certain adjustment margin in the initial stage of resetting, which makes it easy for the operator to align the position. At the same time, after final fixation, it can effectively prevent the wire from sliding out from the side due to wind vibration or external force, thus solving the problems of inconvenient adjustment and poor anti-detachment effect of traditional wire clamping devices.

[0019] The clamp fixing seat 2 at the bottom of the device is the key to achieving rapid installation. It uses a flexible binding component 21 (such as pre-stranded wire) to replace the traditional rigid metal clamp or bolt fastening method. The pre-stranded wire has good flexibility and fatigue resistance, which can better adapt to the surface shape and diameter fluctuation of the conductor, provide uniform stress distribution, and avoid excessive local stress that could damage the conductor. The arc-shaped part 221 of the clamp body 22 ensures the fit with the surface of the connected parts 3 such as the insulated wire bottle.

[0020] Furthermore, this invention introduces a power transmission mechanism. When the winding structure 23 (such as a winch or tightening wheel) rotates, it continuously tightens the flexible binding member 21, thereby firmly binding the clamp to the insulated wire bottle. Simultaneously, the rotational power of the winding structure 23 is not consumed in isolation, but is transmitted to the upper support arm 11 through an independent connector 3. As a result, when the operator performs a single winding tightening action, the support arm 11 is synchronously moved downwards. This linkage process produces two crucial beneficial effects: First, it achieves simultaneous completion of "binding" and "tightening," greatly simplifying the operation process and improving work efficiency, making it particularly suitable for rapid handling in live emergency situations; second, it ensures that the final fixed state of the wire is scientific and reliable. As the binding member tightens, the pressure of the anti-derailment clamp 12 on the wire gradually increases until it is stably confined in the ideal position. This dynamic downward pressure ensures more sufficient contact between the wire and the clamp, resulting in better fixation, and the entire process is smooth and continuous, requiring no step-by-step operation.

[0021] In summary, this technical solution, through ingenious mechanical linkage design, integrates the functions of conductor binding and spatial limiting into a single, continuous action, fundamentally solving the problems of cumbersome operation, low efficiency, and insufficient fixing reliability in existing technologies. Its beneficial effects do not stem from the performance improvement of a single component, but rather from the systemic advantages of the coordinated work of all components: it reduces the labor intensity and skill requirements of operators, improves the safety and efficiency of live-line work, and ensures the long-term stability and reliability of the conductor through uniform force application and dynamic clamping. Compared to the rake structure used in existing technologies, it significantly improves the limiting of the conductor and effectively prevents secondary detachment and displacement due to insufficient limiting capability of the devices used by power workers during live-line installation and resetting of the conductor.

[0022] like Figure 1 , 9 As shown, connector 3 is a columnar structure with an externally threaded outer wall, and is divided into the following sections from bottom to top: The adjusting connecting part 31 is used to connect the support arm 11. The support arm 11 is provided with a threaded through hole 111, which is located in the middle of the two anti-derailment clamps 12 fixed on the support arm 11, so that the two anti-derailment clamps 12 are balanced by force. The external thread structure of the adjusting connecting part 31 is threadedly engaged with the threaded through hole 111. Corresponding to the position of the threaded through hole 111, a limit bolt 112 is installed on the support arm 11. The limit bolt 112 is installed on the side base surface of the support arm 11, and the corresponding support arm 11 is provided with a matching threaded mounting hole that extends through the threaded through hole 111. Thus, when the limit bolt 112 is tightened, the limit bolt... When the end of the bolt 112 abuts against the adjusting connection part 31, the upward force is applied to the anti-derailment clamp 12 during the swing of the conductor. The anti-derailment clamp 12 then transmits the force to the support arm 11, causing the support arm 11 to make a relatively small displacement relative to the adjusting connection part 31 of the connector 3. While reducing the clamping force of the anti-derailment clamp 12 on the conductor, the adjusting connection part 31 of the connector 3 is clamped by the limiting bolt 112. The friction force generated by the clamping limits the movement of the support arm 11, thereby effectively preventing the support arm 11 from making a relatively small displacement with the adjusting connection part 31 of the connector 3 and enhancing the stability of the conductor limit. The lower connecting part 32 is fixedly connected to the winding structure 23 and rotates with it. The rotation of the winding structure 23 winding and tightening the flexible connecting part 3 drives the connecting part 3 to rotate, so that the support arm 11 and the adjusting connecting part 31 move down along the adjusting connecting part 31 in the threaded state, thereby making the tightening and fixing action and the pressing and limiting action work together. Compared to the existing technology where the distance between the upper wire rake and the lower clamp is fixed and the applicable range is small, the connector 3 of the present invention can adjust the support arm 11 and the clamp body 22, and is suitable for the reinstallation and fixing of wires that have come loose from insulated insulated cylinders of different sizes.

[0023] like Figure 4 , 5 As shown in Figures 6 and 7, the winding structure 23 includes: Connecting sleeve 231 tapers in a stepped manner from top to bottom along its axial direction, and is divided into: The upper connecting part 2311 has an internal thread structure on its inner side wall, which is used to connect and fix the lower connecting part 32. The lower end through part 2312 passes through the mounting part 222 from top to bottom and is rotatably connected to it. The corresponding mounting part 222 has an opening structure for mounting the lower end through part 2312. When the lower through portion 2312 is rotatably mounted on the opening structure of the mounting portion 222, the diameter of the upper connecting portion 2311 is larger than that of the opening structure of the mounting portion 222, so as to avoid the upper connecting portion 2311 being unable to form an upper limit due to insufficient diameter.

[0024] The winding sleeve 232 has an internally threaded inner wall and a limiting ring 233 on its outer wall. The winding sleeves 232 on the upper and lower sides of the limiting ring 233 are as follows: The upper through-part 2321 passes through the mounting part 222 from bottom to top and is fixed in conjunction with the lower through-part 2312, and is used in conjunction with the limiting ring 233 to limit the mounting part 222; The lower winding part 2323 has a through groove 2324 for the installation and connection of the flexible binding member 21. The end of the flexible binding member 21 can be installed in the through groove 2324, so that the flexible binding member 21 can be tightened when rotating. Fastener 234 is fixedly installed at the lower winding part 2323 cylinder opening and is used to tighten the flexible binding member 21. Compared with the prior art, the flexible binding member 21 is usually fixed by binding both ends and placing it in the through groove 2324 or binding each end and placing it in the through groove 2324. The binding is easy to come loose. The present invention increases the stability of the installation of the flexible binding member 21. That is, the fastener 234 is used to further tighten and fix the installation of the flexible binding member 21, thereby avoiding the situation that the binding is loose and cannot be fully tightened during the winding and tightening process.

[0025] Specifically, the connecting sleeve 231 and the winding sleeve 232 are rotated and installed through the opening structure of the mounting part 222, with the upper end limited by the larger diameter upper connecting part 2311 and the lower end limited by the limiting ring 233, ensuring that the connection position of the two is stable and rotated in the mounting part 222. That is, the lower end through part 2312 and the upper end through part 2321 are stably rotated and installed in the mounting part 222, and cooperate with the limiting member 24. Furthermore, the flexible binding member 21 is pressed by the fastener 234 and then wrapped and tightened.

[0026] like Figure 9 As shown, during the rotation and tightening of the flexible binding member 21, the support arm 11 moves downwards following the rotation. If the downward movement of the support arm 11 has enabled the anti-detachment clamp 12 to press the wire, but the flexible binding member 21 has not yet been fully tightened, i.e., not yet fully fixed to the insulating cylinder; or if the downward movement of the support arm 11 has not yet enabled the anti-detachment clamp 12 to press the wire, but the flexible member has been fully tightened, i.e., fully fixed to the insulating cylinder, and cannot be rotated further, this will inevitably affect the installation by the operator. In practical applications, after the wire is placed in the top groove of the insulating cylinder, the vertical movement distance of the wire in the anti-detachment clamp 12 is h, the tightening length reserved by the flexible binding member 21 is l, the pitch of the external thread structure of the connector 3 is p, and the circumference of the outer wall of the lower winding part 2323 is c. During the rotation and tightening of the flexible binding member 21, the movement distance of the support arm 11 relative to the connector 3 is h1. The core of this technical solution lies in the adjustment of the reserved tightening length l of the flexible binding part 21, that is, how much length needs to be reserved so that during the process of the lower winding part 2323 winding and tightening the flexible binding part 21, the clamp body 22 is fixed on the insulated wire bottle, while ensuring that the anti-derailment clamp 12 applies downward pressure to limit the conductor. During the winding and tightening process, it is crucial to avoid a situation where the support arm 11 has moved down a distance sufficient to allow the anti-derailment clamp 12 to press against the conductor, while the flexible binding member 21 has not yet been fully tightened. This situation would result in the clamp body 22 failing to be fully fixed to the insulated cable bottle, and forcibly continuing to tighten may cause the device to deform or break. Alternatively, it is also crucial to avoid a situation where the support arm 11 has moved down a distance sufficient to allow the anti-derailment clamp 12 to press against the conductor, while the flexible binding member 21 has already been fully tightened. This situation would result in the anti-derailment clamp 12 failing to effectively restrict the conductor, allowing the conductor to continue moving within the anti-derailment clamp 12 when blown by wind. Therefore, in h1=l·p / c, h1>h, since the values ​​of the vertical movement distance h of the wire, the circumference c of the lower winding part 2323 and the external thread structure p of the connector 3 have been determined after the component selection and assembly, only the reserved tightening length l can affect the change of the movement distance h1 of the support arm 11 relative to the connector 3. In practical applications, the reserved tightening length l is calculated by the operator based on the vertical movement distance h of the conductor, the circumference c of the outer wall of the lower winding part 2323, and the pitch p of the external thread structure of the connector 3. The allowance can be flexibly reserved according to the actual application. When the winding structure 23 rotates, the flexible binding part 21 is continuously tightened. At this time, since the external thread structure of the upper connecting part 2311 is threadedly engaged with the threaded through hole 111 on the support arm 11, and the conductor is restricted from rotating within the anti-derailment clamp 12, the rotation of the winding structure 23 can drive the support arm 11 to move downward. This causes the anti-derailment clamp 12 to gradually change from the original supporting state to the downward pressing state of the conductor. When the anti-derailment clamp 12 applies downward pressure to achieve the effect of fixing the conductor, the rotation of the winding structure 23 tightens the flexible binding part 21, which can completely fit and fix the arc-shaped part 221 of the clamp body 22 to the outer installation position of the insulating wire bottle. In the case where h1>h, attention should be paid to the stress performance of the material used in the anti-detachment clamp 12 to avoid the material of the anti-detachment clamp 12 being unable to withstand the force due to an excessive difference between h1 and h, which would lead to the failure of the downward pressure limit.

[0027] like Figure 4 , 5As shown in Figure 6, the outer wall of the lower through-part 2312 has an external thread structure, and the internal thread structure of the inner wall of the upper through-part 2321 is threadedly engaged with the external thread structure of the outer wall of the lower through-part 2312. The outer wall of the upper through-part 2321 is uniformly provided with limiting grooves 2322 along its circumference. The limiting grooves 2322 and the limiting member 24 cooperate to limit the rotation of the winding structure 23. The limiting member 24 is a spring-loaded limiting structure. The mounting part 222 should have a slot for the mounting limiting member 24. During the rotation and tightening of the flexible binding member 21, the limiting member 24 cooperates with the limiting groove 2322 to prevent the tightened flexible binding member 21 from springing back, which would prevent the binding action from being able to stably fix the clamp body 22 on the insulated wire bottle. It should be noted that the present invention is not limited to the limiting structure in which the limiting member 24 cooperates with the limiting groove 2322. Any structure that can achieve unidirectional limiting of the rotation action is acceptable.

[0028] like Figure 7 , 8 As shown, the anti-detachment clip 12 includes: The conductor receiving structure 121 has an opening at the top. Specifically, its receiving cavity structure is a U-shaped structure. A connecting fastener is installed at the bottom to connect the support arm 11. That is, the fastener is installed and fixed to the base surface at the end of the support arm 11. It uses insulating material to block the conductor current and prevent the current from damaging the line. At least one limit locking assembly 122 is rotatably mounted on the open end of the wire receiving structure 121 to close the end. It should be noted that two limit locking assemblies 122 can be provided and mirror-mounted on the open end of the wire receiving structure 121 respectively to increase the contact surface between the limit locking assembly 122 and the wire during the pressing action. Limit lock assembly 122 includes: The lower pressure plate 1221 is rotatably mounted on the open end of the wire receiving structure 121; The elastic reset member 1226 is used to connect the lower pressure plate 1221 and the wire receiving structure 121. Here, the elastic reset member 1226 is a torsion spring structure. The lower pressure plate 1221 is provided with a mounting groove for mounting the torsion spring. The other end of the torsion spring is connected to the wire receiving structure 121 to provide the lower pressure plate 1221 with the power to reset. The lower pressure plate 1221 closes the opening of the conductor receiving structure 121, ensuring that the conductor enters the conductor receiving structure 121 from top to bottom after being pressed on the upper part of the lower pressure plate 1221. Then, the elastic reset member 1226 causes the lower pressure plate 1221 to reset and close the opening of the conductor receiving structure 121, preventing the conductor from falling out of the opening of the conductor receiving structure 121. Compared with the open limiting structure in the prior art, the limiting locking assembly 122 can drive the lower pressure plate 1221 to spring back and reset through the elastic reset member 1226, restricting the conductor in the receiving cavity of the conductor receiving structure 121, effectively preventing the conductor from falling off due to line swing.

[0029] like Figure 8 As shown, the lower pressure plate 1221 is a one-piece molded right-angle structure, divided into: The rotating connection part 1222 is rotatably connected to the open end of the wire receiving structure 121; The sealing part 1223 rotates with the rotating connecting part 1222 to open and close the opening end of the wire receiving structure 121. Its upper end face matches the opening of the wire receiving structure 121, and its lower end face has an arc-shaped concave surface to fit the top of the wire. In addition, its lower end face and the receiving cavity of the wire receiving structure 121 are rounded. During use, it can effectively protect the wire, and after installation, it can effectively avoid the situation of severe wire wear due to wire swing. The limiting reinforcement 1224 cooperates with the wire receiving structure 121 to limit the rotation of the rotating connection 1222. Specifically, the inner base surface of the limiting reinforcement 1224 is in contact with the outer base surface of the wire receiving structure 121 on the same side to enhance the restriction of the rotation of the sealing part 1223 when the wire is pressed. The connection between the rotating connection 1222 and the limiting reinforcement 1224 is a fracture zone 1225. Specifically, the thickness of the fracture zone 1225 can be reduced or a groove can be opened at the location to reduce its stress fracture threshold, so that it will break first from the fracture zone 1225 after exceeding the stress threshold. Compared to the existing locking buckle assembly 122, which locks the connection between the conductor and the insulated insulator, making it easy for the pole to tip over in extreme weather due to the conductor swinging violently, the fracture zone 1225 at the connection between the rotating connection 1222 and the limiting reinforcement 1224 mentioned in this invention can, in the event of severe weather and excessive conductor swinging, cause the conductor to drive the sealing part 1223 to rotate along the rotating connection 1222, and cause the limiting reinforcement 1224 to break off from the fracture zone 1225, allowing the conductor to detach and protect the pole, thus preventing the pole from tipping over and injuring people.

[0030] like Figure 2 , 9As shown, the insulating rod body 4 is made of insulating material, and its end is provided with a connector 41 that mates with the fastener 234. Here, the fastener 234 is a hexagonal head bolt structure, and the connector 41 matches its hexagonal hole. When in use, it is inserted into the hexagonal hole. The operating head 5 is detachably installed at the end of the insulating rod body 4 and is used to tighten the limit bolt 112; The operating head 5 is a corner mechanism structure, specifically, it has meshing bevel gears installed inside to change the power output plane. It is equipped with a first connector 51 that matches the connector 41 and a second connector 52 for tightening the limit bolt 112. The first connector 51 and the second connector 52 are adjacent to each other and form a right angle, which facilitates the tightening of the limit bolt 112 after installation. The insulating rod 4 is used to assist power workers in resetting and fixing conductors. During use, the flexible binding member 21 is installed, and the tightening length is adjusted according to the actual situation. The connector 41 is then connected to the fastener 234. After lifting, the conductor is aligned with the opening of the conductor receiving structure 121. The conductor's own weight causes the lower pressure plate 1221 to press down. After the conductor enters the conductor receiving structure 121, the lower pressure plate 1221 resets and seals under the action of the elastic reset member 1226. While the power worker lifts the conductor, the binding loop of the flexible binding member 21 is placed over the outside of the insulating insulated insulator. Further, the power worker rotates the operating lever to activate the connecting rod. The connector 41, in conjunction with the fastener 234, applies a tightening action, thereby driving the lower winding part 2323 to rotate and complete the winding tightening action, further completing the downward pressure and limiting action of the conductor. Furthermore, the insulating rod body 4 is installed with the operating head 5, the connector 41 is fixedly connected to the first connector 51, the second connector 52 is aligned with the limiting bolt 112, and by rotating the insulating rod body 4, the operating head 5 tightens the limiting bolt 112 to limit the support arm 11. Compared with the situation where power workers need to work at height, the present invention allows power workers to reset and fix the detached conductor from the ground or at low altitude, greatly reducing the operation risk.
