Description

Technical Field

[0001] This invention relates to the field of power fittings technology, specifically a double-fixed jumper spacer bar. Background Technology

[0002] In high-voltage and ultra-high-voltage transmission lines, jumpers, as key components connecting the conductors on both sides of tension towers, are exposed to complex outdoor environments for extended periods. They are susceptible to factors such as strong winds, icing, and conductor galloping, which can lead to fatigue damage, conductor displacement, or even breakage, seriously threatening the safe and stable operation of transmission lines.

[0003] Chinese Patent Publication No. CN202310920331.6 discloses a spacer bar, which mainly utilizes a connecting rod and locking block to achieve a greater range of motion, adapting to the position of the cable, reducing the need for manual cable pulling, lowering assembly difficulty, and avoiding the inconvenience of high-altitude operations. A retraction tool allows the connecting rod to be easily pulled back towards the rear of the conduit via a pin, achieving rapid positioning and fixing, and shortening the installation time of the spacer bar. However, this spacer bar uses a single-layer wire clamping structure, relying on the friction of the clamping block to fix the conductor. Under strong winds or conductor galloping conditions, the conductor is prone to loosening and displacement. Furthermore, existing spacers mostly rely on passive damping structures for vibration resistance, which is insufficient to cope with complex and variable outdoor vibration loads, and long-term operation can easily lead to conductor fatigue and breakage. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a double-fixed jumper spacer bar, comprising: a central support body, the central support body being configured as a hollow frame, a wire clamping assembly and a protective tube being respectively installed inside the central support body, the protective tube being fixedly connected to the wire clamping assembly, a vibration signal acquisition device being fixedly installed at the center of the protective tube, and a reinforcing rod penetrating the surface of both the protective tube and the central support body;

[0005] An anti-sway component is threadedly installed at the middle of the bottom of the central support body, and the anti-sway component is connected to a vibration signal acquisition device via an electrical signal.

[0006] The anti-sway component includes an anti-sway mounting base, with a hinged shaft mounted on the bottom of the mounting base. Anti-sway actuators are fixedly mounted on the surface of the hinged shaft. When a vibration signal acquisition device inside the protective tube detects that the conductor vibration data exceeds a threshold, it sends an electrical signal trigger command to the anti-sway component. The anti-sway mounting base, acting as a power and signal relay node, receives the command and drives the internal transmission mechanism, causing the hinged shaft to deflect at an angle. This deflection directly causes the anti-sway actuators on both sides to swing synchronously. The swing angle and frequency of the anti-sway actuators can be dynamically adjusted according to the vibration data, adapting to vibration conditions under different wind speeds and conductor tensions, thus having a wide range of applications.

[0007] Preferably, the anti-sway mounting base is fixedly installed at the bottom of the central support body by a screw, and the anti-sway actuator is connected to the vibration signal acquisition device by an electrical signal.

[0008] Preferably, the anti-sway actuator includes an arm support frame, and two arm supports are provided. A counterweight is fixedly mounted on the surface of each of the two arm supports. A sensor mounting slot is provided inside each counterweight, and a vibration sensor is fixedly mounted inside the sensor mounting slot. The vibration sensor inside the counterweight, through the fitting structure of the sensor mounting slot, collects the vibration feedback data of the counterweight in real time and transmits it back to the vibration signal acquisition unit, forming a closed-loop control.

[0009] Preferably, the arm support extends through the counterweight into the sensor mounting slot, and the arm support abuts against both sides of the vibration sensor. The vibration sensor is connected to the vibration signal acquisition unit via an electrical signal. As a rigid support structure, the arm support transmits the torque of the rotating shaft to the counterweight. The counterweight generates a reverse damping force through its own inertia, forming a counterforce with the lateral vibration of the conductor, thereby offsetting the sway amplitude of the conductor. The abutment design between the arm support and the vibration sensor enhances the transmission efficiency of vibration damping and improves the response speed of vibration damping.

[0010] Preferably, the central support body includes a support ring, the outer periphery of which is provided with an assembly groove, and the inner side of which is provided with a stop bar. A positioning plate is fixedly installed on the surface of the stop bar. The support ring, as the main frame, adopts a double-layer hollow frame structure. First, the evenly distributed assembly grooves on the outer periphery precisely correspond to the clamping arms of the wire clamping assembly, achieving rapid positioning and installation of the clamping arms. This ensures that multiple sets of wire clamping assemblies are symmetrically and evenly distributed on the support ring. The stop bar on the inner side of the support ring is positioned opposite to the outer assembly groove, limiting the installation position of the protective tube and preventing displacement of the protective tube inside the support ring.

[0011] Preferably, the support ring is configured as a double-layer hollow frame, the assembly slots and the stop bars are arranged opposite each other, and the positioning plates are fixedly installed at both ends of the reinforcing rod. After the protective tube and the wire clamping assembly are fixedly connected, the whole is placed into the internal cavity of the support ring. The stop bars provide lateral limitation for the protective tube, ensuring that the central axis of the protective tube and the support ring coincides. The reinforcing rod passes through the corresponding mounting holes of the protective tube and the support ring, and both ends are locked and positioned by the positioning plates, which can prevent the reinforcing rod from loosening or displacing during the stress process, ensuring the rigidity and stability of the overall structure, so that the protective tube, the wire clamping assembly and the support ring form a rigid whole, completing the assembly of the spacer core structure. When the wire clamping assembly clamps the wire and bears tension, the tension will be transmitted to the protective tube through the clamping arm, and then distributed to the double-layer hollow frame of the support ring through the reinforcing rod. The double-layer structure of the support ring and the evenly distributed assembly slots and stop bars can evenly distribute the multi-directional forces to the entire frame, avoiding fatigue damage to local components due to stress concentration.

[0012] Preferably, the wire clamping assembly includes a clamping arm, with a clamping block mounting seat rotatably mounted inside the clamping arm. A clamping component is fitted onto the surface of the clamping arm and the clamping block mounting seat. The clamping arm is pre-fixed to the protective tube and assembled together inside the support ring of the central support body. The clamping arm precisely corresponds to the assembly groove on the periphery of the support ring. The positioning effect of the assembly groove ensures that the installation position of the clamping arm on the central support body does not shift, providing a precise spatial positioning basis for subsequent wire clamping. The clamping tension of the wire is first transmitted to the clamping arm through the clamping block, and then distributed to the overall frame of the central support body through the protective tube. Simultaneously, the clamping arm is fixedly connected to the protective tube, thereby enhancing the structural rigidity of the assembly and improving the stability of force transmission.

[0013] Preferably, the clamping arm and the protective tube are fixedly connected inside the support ring, and the clamping arm and the assembly groove are correspondingly arranged. The clamping component is configured as an assembly structure. Because the clamping component is an assembly structure, the clamping distance between the upper and lower clamping blocks can be adjusted according to the specifications of the wire, adapting to jumper wires of different diameters. After clamping, the first layer of fixation for the wire is formed. The clamping arm and the protective tube are fixedly connected, and the protective tube is locked to the central support body through a reinforcing rod. When the clamping component completes the direct clamping of the wire, the wire tension generated by the clamping is transmitted to the protective tube through the clamping arm, and then distributed to the overall frame of the central support body through the reinforcing rod. This combines the clamping force of the wire with the rigid support of the spacer bar, forming a second layer of fixation for the wire. Through the effect of double clamping fixation, it can effectively resist the tension and impact forces under extreme working conditions such as strong winds and wire dancing, preventing the wire from loosening or shifting, and significantly improving the firmness and stability of the wire clamping.

[0014] Preferably, the clamping component includes an upper clamping block and a lower clamping block, both of which have anti-slip serrations inside. The operator places the jumper wire inside the lower clamping block. The anti-slip serrations on the inner wall of the lower clamping block first contact the wire surface. The concave-convex structure of the anti-slip serrations increases the contact friction with the wire, preventing the wire from sliding or shifting during placement, thus completing the initial positioning and contact of the wire. The clamping block mounting base is rotatably installed inside the clamping arm. Using the upper clamping block as the actuating end, rotating the clamping block mounting base moves the upper clamping block towards the lower clamping block until the anti-slip serrations of both the upper and lower clamping blocks are tightly against the wire surface, forming a clamping and locking mechanism for the wire.

[0015] Preferably, the upper clamping block is rotatably adapted to the wire clamping arm via a clamping block mounting base, and both the upper and lower clamping blocks are semi-circular structures made of insulating material. Since both the upper and lower clamping blocks are semi-circular structures made of insulating material, the anti-slip serrations on the inner wall of the clamping components increase the contact friction with the wire during continuous clamping, fundamentally preventing the wire from sliding or rotating after clamping. Simultaneously, the semi-circular structure of the upper and lower clamping blocks precisely matches the arc-shaped surface of the wire, ensuring that the clamping force is evenly distributed on the wire surface, avoiding localized stress concentration that could damage the wire sheath. The insulating material of the clamping blocks also isolates metal components, preventing electrochemical corrosion and leakage of the wire, thus providing comprehensive protection for the wire while clamping it.

[0016] This invention provides a double-fixed jumper spacer. It has the following advantages:

[0017] (i) When the wire clamping assembly clamps the wire and bears the tension, the tension is transmitted to the protective tube through the clamping arm, and then distributed to the double-layer hollow frame of the support ring through the reinforcing rod. The double-layer structure of the support ring and the evenly distributed assembly grooves and baffles can evenly distribute the multi-directional forces to the entire frame, avoiding fatigue damage to local components due to stress concentration.

[0018] (ii) This double-fixed jumper spacer bar forms a direct clamping and fixing of the conductor through the anti-slip clamping of the upper and lower clamping blocks. Furthermore, the clamping force is distributed to the entire spacer bar through the rigid connection between the clamping arm and the protective tube and the central support body, thereby achieving the effect of double-fixed clamping of the conductor. It can effectively resist the pulling and impact forces under extreme working conditions such as strong winds and conductor galloping, prevent the conductor from loosening or shifting, and greatly improve the firmness and stability of the conductor clamping.

[0019] (III) This double-fixed jumper spacer bar, with its upper and lower clamps being semi-circular structures made of insulating material, increases the contact friction with the wire during continuous clamping of the wire by the anti-slip serrations on the inner wall of the clamping parts. This fundamentally prevents the wire from sliding or rotating after clamping. At the same time, the semi-circular structure of the upper and lower clamps precisely matches the arc-shaped surface of the wire, so that the clamping force is evenly distributed on the surface of the wire, avoiding local stress concentration that could damage the wire sheath. The insulating material of the clamps can also isolate the metal parts, preventing electrochemical corrosion and leakage of the wire, thus providing comprehensive protection for the wire while clamping it.

[0020] (iv) The double fixed jumper spacer, after the vibration signal acquisition device in the protective tube detects that the conductor vibration data exceeds the threshold, will send an electrical signal trigger command to the anti-sway component. The anti-sway mounting base, as the power and signal transfer node, drives the internal transmission mechanism after receiving the command, which drives the hinge shaft to deflect at an angle. The deflection of the hinge shaft directly drives the anti-sway actuator arms on both sides to swing synchronously. The swing angle and frequency of the anti-sway actuator arms can be dynamically adjusted according to the vibration data, adapting to vibration conditions under different wind speeds and conductor tensions, and has a wide range of applications.

[0021] (v) The double fixed jumper spacer uses the arm support as a rigid support structure to transmit the torque of the rotating shaft to the counterweight. The counterweight generates a reverse damping force through its own inertia, which forms a reverse force with the transverse vibration of the wire, thereby offsetting the swing amplitude of the wire. The contact design between the arm support and the vibration sensor enhances the transmission efficiency of vibration damping and improves the response speed of vibration reduction.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First embodiment, such as Figures 1 to 10 As shown, the present invention provides a technical solution: a double-fixed jumper spacer bar, comprising: a central support body 4, the central support body 4 being configured as a hollow frame, the interior of the central support body 4 being respectively provided with a wire clamping assembly 3 and a protective tube 1, the protective tube 1 being fixedly connected to the wire clamping assembly 3, a vibration signal acquisition device 5 being fixedly installed at the center of the protective tube 1, and a reinforcing rod 6 penetrating the surface of both the protective tube 1 and the central support body 4;

[0035] Anti-sway component 2 is threadedly installed at the middle of the bottom of the central support body 4, and the anti-sway component 2 is connected to the vibration signal acquisition device 5 via an electrical signal.

[0036] The anti-sway component 2 includes an anti-sway mounting base 21, with a hinged rotating shaft 23 mounted on the bottom of the mounting base 21. Anti-sway actuator arms 22 are fixedly mounted on the surface of the hinged rotating shaft 23. When the vibration signal acquisition device 5 inside the protective tube 1 detects that the conductor vibration data exceeds a threshold, it sends an electrical signal trigger command to the anti-sway component 2. The anti-sway mounting base 21, acting as a power and signal relay node, receives the command and drives the internal transmission mechanism, causing the hinged rotating shaft 23 to deflect at an angle. The deflection of the hinged rotating shaft 23 directly causes the anti-sway actuator arms 22 on both sides to swing synchronously. The swing angle and frequency of the anti-sway actuator arms 22 can be dynamically adjusted according to the vibration data, adapting to vibration conditions under different wind speeds and conductor tensions, thus having a wide range of applications.

[0037] The anti-sway mounting base 21 is fixedly installed at the bottom of the central support body 4 by a screw, and the anti-sway actuator 22 is connected to the vibration signal acquisition device 5 by an electrical signal.

[0038] The anti-sway actuator 22 includes an arm support 221, of which two arms support 221 are provided. A counterweight 222 is fixedly mounted on the surface of each arm support 221. A sensor mounting slot 223 is provided inside each counterweight 222, and a vibration sensor 224 is fixedly mounted inside the sensor mounting slot 223. The vibration sensor 224 inside the counterweight 222 collects vibration feedback data of the counterweight 222 in real time through the fitting structure of the sensor mounting slot 223, and transmits it back to the vibration signal acquisition unit 5, forming a closed-loop control.

[0039] The arm support 221 extends through the counterweight 222 into the sensor mounting slot 223, and the arm support 221 abuts against both sides of the vibration sensor 224. The vibration sensor 224 is connected to the vibration signal acquisition unit 5 via an electrical signal. As a rigid support structure, the arm support 221 transmits the torque of the rotating shaft to the counterweight 222. The counterweight 222 generates a reverse damping force through its own inertia, forming a counterforce with the lateral vibration of the conductor, thereby offsetting the sway amplitude of the conductor. The abutting design between the arm support 221 and the vibration sensor 224 enhances the transmission efficiency of vibration damping and improves the response speed of vibration damping.

[0040] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 4As shown, the central support body 4 includes a support ring 41. An assembly groove 42 is provided on the periphery of the support ring 41, and a stop bar 43 is provided on the inner side of the support ring 41. A positioning plate 44 is fixedly installed on the surface of the stop bar 43. The support ring 41, as the main frame, adopts a double-layer hollow frame structure. The evenly distributed assembly grooves 42 on the periphery precisely correspond to the clamping arms 31 of the wire clamping assembly 3, enabling rapid positioning and installation of the clamping arms 31. This ensures that multiple sets of wire clamping assemblies 3 are symmetrically and evenly distributed on the support ring 41. The stop bar 43 on the inner side of the support ring 41 is positioned opposite to the outer assembly groove 42, limiting the installation position of the protective tube 1 and preventing displacement of the protective tube 1 inside the support ring 41. The support ring 41 is configured as a double-layer hollow frame, with the assembly grooves 42 and the stop bar 43 positioned opposite each other. The positioning plate 44 is fixedly installed at both ends of the reinforcing rod 6. After the protective tube 1 is fixedly connected to the wire clamping assembly 3, the whole assembly is placed into the internal cavity of the support ring 41. The stop bar 43 provides lateral limitation for the protective tube 1, ensuring that the central axis of the protective tube 1 and the support ring 41 coincides. The reinforcing rod 6 passes through the corresponding mounting holes of the protective tube 1 and the support ring 41, and is locked and positioned at both ends by the positioning plate 44. This prevents the reinforcing rod 6 from loosening or shifting during the stress process, ensuring the rigidity and stability of the overall structure. This makes the protective tube 1, the wire clamping assembly 3, and the support ring 41 form a rigid whole, completing the assembly of the core structure of the spacer bar. When the wire clamping assembly 3 clamps the wire and bears tension, the tension is transmitted to the protective tube 1 through the clamping arm 31, and then distributed to the double-layer hollow frame of the support ring 41 through the reinforcing rod 6. The double-layer structure of the support ring 41, along with the evenly distributed assembly grooves 42 and the stop bar 43, can evenly distribute the multi-directional forces to the entire frame, avoiding fatigue damage to local components due to stress concentration.

[0041] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 5 to 6 As shown, the wire clamping assembly 3 includes a clamping arm 31, with a clamping block mounting base 33 rotatably mounted inside the clamping arm 31. A clamping member 32 is mounted on the surface of the clamping block mounting base 33 and the clamping arm 31. The clamping arm 31 is pre-fixed to the protective tube 1 and assembled together inside the support ring 41 of the central support body 4. The clamping arm 31 precisely corresponds to the assembly groove 42 on the periphery of the support ring 41. The positioning effect of the assembly groove 42 ensures that the installation position of the clamping arm 31 on the central support body 4 does not shift, providing a precise spatial positioning basis for subsequent wire clamping. The clamping tension of the wire is first transmitted to the clamping arm 31 through the clamping block, and then distributed to the overall frame of the central support body 4 through the protective tube 1. Simultaneously, the clamping arm 31 is fixedly connected to the protective tube 1, thereby enhancing the structural rigidity of the assembly and improving the stability of force transmission.

[0042] The clamping arm 31 is fixedly connected to the protective tube 1 inside the support ring 41, and the clamping arm 31 is correspondingly arranged with the assembly groove 42. The clamping member 32 is configured as an assembly structure. Since the clamping member 32 is an assembly structure, the clamping distance of the upper clamping block 322 and the lower clamping block 323 can be adjusted according to the specifications of the wire to adapt to jumper wires of different diameters, forming the first layer of fixation for the wire after clamping. The clamping arm 31 and the protective tube 1 are fixedly connected. The protective tube 1 is then locked to the central support body 4 through the reinforcing rod 6. After the clamping member 32 completes the direct clamping of the conductor, the conductor tension generated by the clamping will be transmitted to the protective tube 1 through the clamping arm 31, and then distributed to the overall frame of the central support body 4 through the reinforcing rod 6. This combines the clamping force of the conductor with the rigid support of the spacer bar to form a second layer of fixation for the conductor. Through the effect of double clamping fixation, it can effectively resist the tension and impact under extreme working conditions such as strong winds and conductor galloping, prevent the conductor from loosening or shifting, and greatly improve the firmness and stability of the conductor clamping.

[0043] The clamping member 32 includes an upper clamping block 322 and a lower clamping block 323. The upper clamping block 322 and the lower clamping block 323 have anti-slip teeth 321 inside. When the operator places the jumper wire inside the lower clamping block 323 of the clamping member 32, the anti-slip teeth 321 on the inner wall of the lower clamping block 323 first contact the surface of the wire. The concave-convex structure of the anti-slip teeth 321 increases the contact friction with the wire, preventing the wire from sliding or shifting during placement, thus completing the initial positioning and contact of the wire. The clamping block mounting base 33 is rotatably installed inside the clamping arm 31. Using the upper clamping block 322 as the actuating end, rotating the clamping block mounting base 33 causes the upper clamping block 322 to move closer to the lower clamping block 323 until the anti-slip teeth 321 of both the upper and lower clamping blocks 322 are tightly in contact with the surface of the wire, forming a clamping and locking mechanism for the wire.

[0044] The upper clamping block 322 is rotatably adapted to the clamping arm 31 via the clamping block mounting base 33. The upper clamping block 322 and the lower clamping block 323 are both semi-circular structures made of insulating material. Both the upper clamping block 322 and the lower clamping block 323 are semi-circular structures made of insulating material. During continuous clamping of the wire, the anti-slip teeth 321 on the inner wall of the clamping member 32 increase the contact friction with the wire, fundamentally preventing the wire from sliding or rotating after clamping. Simultaneously, the semi-circular structure of the upper and lower clamping blocks 323 precisely matches the arc-shaped surface of the wire, ensuring that the clamping force is evenly distributed on the wire surface, avoiding localized stress concentration that could damage the wire sheath. The insulating material of the clamping blocks also isolates metal components, preventing electrochemical corrosion and leakage of the wire, thus providing comprehensive protection for the wire while clamping it.

[0045] In use, the support ring 41 serves as the main frame and adopts a double-layer hollow frame structure. First, the assembly grooves 42 evenly distributed on the periphery correspond precisely with the clamping arms 31 of the wire clamping assembly 3, so as to achieve rapid positioning and installation of the clamping arms 31. This ensures that multiple sets of wire clamping assemblies 3 are symmetrically and evenly distributed on the support ring 41. The baffle 43 on the inner side of the support ring 41 is set opposite to the outer assembly grooves 42, which can limit the installation position of the protective tube 1 and prevent the protective tube 1 from shifting inside the support ring 41.

[0046] After the protective tube 1 is fixedly connected to the wire clamping assembly 3, the whole assembly is placed into the internal cavity of the support ring 41. The stop bar 43 provides lateral limitation for the protective tube 1, ensuring that the central axis of the protective tube 1 and the support ring 41 coincides. The reinforcing rod 6 passes through the corresponding mounting holes of the protective tube 1 and the support ring 41, and is locked and positioned at both ends by the positioning plate 44. This prevents the reinforcing rod 6 from loosening or shifting during the stress process, ensuring the rigidity and stability of the overall structure. This makes the protective tube 1, the wire clamping assembly 3, and the support ring 41 form a rigid whole, completing the assembly of the core structure of the spacer bar. When the wire clamping assembly 3 clamps the wire and bears tension, the tension is transmitted to the protective tube 1 through the clamping arm 31, and then distributed to the double-layer hollow frame of the support ring 41 through the reinforcing rod 6. The double-layer structure of the support ring 41, along with the evenly distributed assembly grooves 42 and the stop bar 43, can evenly distribute the multi-directional forces to the entire frame, avoiding fatigue damage to local components due to stress concentration.

[0047] The clamping arm 31 is pre-fixed to the protective tube 1 and assembled together inside the support ring 41 of the central support body 4. The clamping arm 31 and the assembly groove 42 on the periphery of the support ring 41 are precisely aligned. The positioning effect of the assembly groove 42 ensures that the installation position of the clamping arm 31 on the central support body 4 does not shift, providing a precise spatial positioning basis for subsequent wire clamping. The clamping force of the wire is first transmitted to the clamping arm 31 through the clamping block, and then distributed to the overall frame of the central support body 4 through the protective tube 1. At the same time, the clamping arm 31 is fixedly connected to the protective tube 1, thereby enhancing the structural rigidity of the component and improving the stability of force transmission.

[0048] The clamping arm 31 and the protective tube 1 are fixedly connected. The protective tube 1 is then locked to the central support body 4 through the reinforcing rod 6. After the clamping member 32 completes the direct clamping of the conductor, the conductor tension generated by the clamping will be transmitted to the protective tube 1 through the clamping arm 31, and then distributed to the overall frame of the central support body 4 through the reinforcing rod 6. This combines the clamping force of the conductor with the rigid support of the spacer bar to form a second layer of fixation for the conductor. Through the effect of double clamping fixation, it can effectively resist the tension and impact under extreme working conditions such as strong winds and conductor galloping, prevent the conductor from loosening or shifting, and greatly improve the firmness and stability of the conductor clamping.

[0049] The worker places the jumper wire inside the lower clamping block 323 of the clamping member 32. The anti-slip teeth 321 on the inner wall of the lower clamping block 323 first contact the surface of the wire. The concave and convex structure of the anti-slip teeth 321 can increase the contact friction with the wire, preventing the wire from sliding or shifting during placement, thus completing the initial positioning and fitting of the wire. The clamping block mounting base 33 is rotatably installed inside the clamping arm 31. The upper clamping block 322 is the actuating end. By rotating the clamping block mounting base 33, the upper clamping block 322 is driven to move towards the lower clamping block 323 until the anti-slip teeth 321 of the upper clamping block 322 and the lower clamping block 323 are tightly fitted to the surface of the wire, forming a clamping and locking of the wire.

[0050] Both the upper clamping block 322 and the lower clamping block 323 are semi-circular structures made of insulating material. During the continuous clamping of the wire, the anti-slip teeth 321 on the inner wall of the clamping part 32 increases the contact friction with the wire, fundamentally preventing the wire from sliding or rotating after clamping. At the same time, the upper and lower clamping blocks 323 are semi-circular structures that precisely match the arc-shaped surface of the wire, so that the clamping force is evenly distributed on the surface of the wire, avoiding local stress concentration that could damage the wire sheath. The insulating material of the clamping blocks can also isolate metal parts, preventing electrochemical corrosion and leakage of the wire, thus achieving comprehensive protection for the wire while clamping.

[0051] When the vibration signal acquisition device 5 inside the protective tube 1 detects that the conductor vibration data exceeds the threshold, it will send an electrical signal trigger command to the anti-sway component 2. The anti-sway mounting base 21, as the power and signal relay node, drives the internal transmission mechanism after receiving the command, which drives the hinge shaft 23 to deflect at an angle. The deflection of the hinge shaft 23 directly drives the anti-sway actuator arms 22 on both sides to swing synchronously. The swing angle and frequency of the anti-sway actuator arms 22 can be dynamically adjusted according to the vibration data, adapting to vibration conditions under different wind speeds and conductor tensions, and has a wide range of applications.

[0052] The vibration sensor 224 inside the counterweight 222 collects the vibration feedback data of the counterweight 222 in real time through the fitting structure of the sensor mounting slot 223, and transmits it back to the vibration signal acquisition unit 5 to form a closed-loop control.

[0053] The arm support 221, as a rigid support structure, transmits the torque of the rotating shaft to the counterweight 222. The counterweight 222 generates a reverse damping force through its own inertia, which forms a reverse force with the lateral vibration of the conductor, thereby offsetting the swing amplitude of the conductor. The contact design between the arm support 221 and the vibration sensor 224 enhances the transmission efficiency of vibration damping and improves the response speed of vibration reduction.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
