Description

Technical Field

[0001] This utility model relates to the field of power transmission equipment manufacturing technology, specifically to a spacer bar anti-dash stabilization device based on nano-anti-aging materials. Background Technology

[0002] In the field of ultra-high voltage power transmission, ensuring the stable operation of transmission lines is of paramount importance. With the continuous growth of electricity demand, ultra-high voltage transmission lines bear the heavy responsibility of large-capacity, long-distance power transmission, and the safety and reliability of their operation are directly related to the stability of power supply.

[0003] Because the lines are exposed to the outdoors for extended periods, they are subject to factors such as wind loads and temperature changes, which cause conductors to sway and expand and contract with temperature. Conventional connection methods cannot flexibly adapt to these changes, leading to stress concentration at the connection points. This can easily cause loosening, wear, or even conductors to detach from the spacers. UHV transmission lines are widely distributed and exposed to harsh environments such as strong winds, acid rain, and ultraviolet radiation for extended periods, resulting in rapid aging. The operating conditions of transmission lines are complex and diverse, with conductor movements including horizontal swaying, vertical jumping, and torsion. Existing spacer structures often cannot maintain stable connections and effective anti-galloping performance when dealing with these complex movements. This makes the spacers insufficiently adaptable to different operating conditions and unable to meet the ever-increasing demands for safe and stable operation of UHV transmission lines. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a spacer bar anti-galloping stabilization device based on nano-anti-aging materials, which solves the problems of easy aging of spacer bars, unstable conductor connections, insufficient anti-galloping capability, and poor adaptability to complex working conditions in ultra-high voltage transmission lines.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spacer bar anti-galling stabilization device based on nano-anti-aging materials, comprising: a rod body, a connecting device slidably connected to the outer wall of the rod body, the connecting device being sleeved on the outer wall of the conductor by rotation, a balancing device symmetrically fixedly connected to the outer wall of the rod body, the balancing device preventing galling through the elastic force of the elastic structure; the connecting device includes a wrapping rod, a locking ring symmetrically fixedly connected to the outer wall of the wrapping rod, a buckle slidably connected to the outer wall of the locking ring, a sliding rod slidably connected to the inner walls of the locking ring and the buckle, the outer wall of the sliding rod extending to the outside of the buckle through a round rod, and the round rod being fixedly connected to the outer wall of the sliding rod, a compression spring fixedly connected to the outer wall of the sliding rod. The design of the buckle and the locking ring, through the sliding rod and the compression spring, achieves convenient and secure locking, facilitating on-site installation and disassembly, while ensuring that it will not be accidentally loosened due to vibration or other reasons during operation.

[0008] Preferably, there are two rods. The outer wall of the wrapping rod is rotatably connected to the outer wall of the rod. The outer wall of the buckle is symmetrically fixedly connected to the outer wall of the rod. The end of the compression spring away from the slide rod is fixedly connected to the inner wall of the buckle. The wrapping rod can rotate on the outer wall of the rod. With the cooperation of the first ball joint and the wire clamp, it can flexibly adapt to the position change of the conductor under different working conditions, reduce the stress concentration at the connection part caused by factors such as line shaking and thermal expansion and contraction, and ensure a stable connection with the conductor.

[0009] Preferably, the inner wall of the wrapping rod is rotatably connected to a first ball joint, and the outer wall of the first ball joint is fixedly connected to a nano anti-aging rod. The end of the nano anti-aging rod away from the ball joint is rotatably connected to a wire clamp, and the inner wall of the wire clamp is in contact with a wire. By using the nano anti-aging rod, the special properties of nanomaterials are utilized to effectively delay the aging of materials under harsh environments such as long-term strong winds, acid rain, and ultraviolet radiation.

[0010] Preferably, the balancing device includes a housing, and a counterweight is disposed inside the housing. The inner wall of the counterweight is rotatably connected to a second ball joint. When the conductor is subjected to external forces such as wind and vibrates or tends to dance, the elastic force and the inertia of the counterweight are used to generate a counteracting force to offset part of the vibration energy and suppress the amplitude and frequency of the conductor's dance.

[0011] Preferably, the outer wall of the housing is symmetrically and fixedly connected to the outer wall of the rod, and the outer wall of the second ball joint is arranged in a circumferential array along the central axis of the counterweight.

[0012] Preferably, a compression spring is fixedly connected to the outer wall of the second ball joint via a round rod. A slide cylinder is fixedly connected to the end of the compression spring away from the round rod. A universal joint is rotatably connected to the end of the slide cylinder away from the second ball joint. The universal joint is rotatably connected to the inner wall of the housing. The inner wall of the slide cylinder is slidably connected to the round rod fixedly connected to the outer wall of the ball joint. The first ball joint, the second ball joint, and the universal joint enable the various parts of the device to rotate flexibly in multiple directions, adapting to the complex motion state of the wire. Regardless of whether the wire is moving horizontally, vertically, or tortuously, it can maintain a stable connection and effective anti-galloping effect.

[0013] (III) Beneficial Effects

[0014] This invention provides a spacer bar anti-dashment stabilization device based on nano-anti-aging materials. It has the following beneficial effects:

[0015] This utility model utilizes a combination of a connecting device and a balancing device. The connecting device's outer sleeve can rotate, working in conjunction with the first ball joint and the wire clamp to flexibly adapt to changes in the conductor's position under different operating conditions. This reduces stress concentration at the connection point caused by factors such as line vibration and thermal expansion and contraction, ensuring a stable connection with the conductor. The counterweight, along with multiple second ball joints, compresses springs, slides, universal joints, and other structures. When the conductor is subjected to external forces such as wind and exhibits a tendency to vibrate or gallop, the elastic force and the inertia of the counterweight generate a counterforce to offset some of the vibration energy, maintaining a stable connection and providing effective anti-galloping protection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-7 This utility model provides a technical solution: a spacer bar anti-danceling and stabilizing device based on nano-anti-aging materials, comprising:

[0027] The rod body 1 has a connecting device 2 slidably connected to its outer wall. The connecting device 2 is sleeved on the outer wall of the conductor by rotation. The outer wall of the rod body 1 is symmetrically fixed with a balancing device 3. The balancing device 3 uses the elasticity of the elastic structure to prevent galloping. This utility model is mainly composed of the rod body 1, the connecting device 2, and the balancing device 3. The various parts cooperate with each other to achieve a flexible and stable connection with the conductor, excellent anti-aging performance, and efficient anti-galloping function.

[0028] The connecting device 2 includes a wrapping rod 20. A locking ring 21 is symmetrically fixedly connected to the outer wall of the wrapping rod 20. A buckle 22 is slidably connected to the outer wall of the locking ring 21. A sliding rod is slidably connected to the inner walls of the locking ring 21 and the buckle 22. The outer wall of the sliding rod extends to the outside of the buckle 22 via a round rod, and the round rod is fixedly connected to the outer wall of the sliding rod. A compression spring 35 is fixedly connected to the outer wall of the sliding rod. There are two rod bodies 1. The outer wall of the wrapping rod 20 is rotatably connected to the outer wall of the rod body 1. The outer wall of the buckle 22 is symmetrically fixedly connected to the outer wall of the rod body 1. The end of the compression spring 35 furthest from the sliding rod is fixedly connected to the inner wall of the buckle 22. During installation, the worker places the wrapping rod 20 into the connecting device 2. Align the outer wall of the wrapping rod 20 with the outer wall of the rod body 1, and then pull the round rod outside the buckle 22. During this process, the round rod slides on the inner wall of the buckle 22. Rotate the connecting device 2. Since the outer wall of the buckle 22 is symmetrically fixedly connected to the outer wall of the rod body 1, the outer wall of the wrapping rod 20 is symmetrically fixedly connected to the locking ring 21. Then, during the sliding process of the buckle 22 and the locking ring 21, the sliding rod can be released until the elastic force of the compression spring 35 pushes the sliding rod to slide on the inner wall of the locking ring 21. When you hear the collision sound produced by the sliding rod and the inner wall of the locking ring 21, the elastic force of the compression spring 35 continues to act to ensure that the buckle 22 and the locking ring 21 are tightly connected and will not be accidentally released due to vibration or other reasons.

[0029] The inner wall of the wrapping rod 20 is rotatably connected to a first ball joint 23, and the outer wall of the first ball joint 23 is fixedly connected to a nano-anti-aging rod 24. A wire clamp 25 is rotatably connected to the end of the nano-anti-aging rod 24 away from the ball joint. A wire is in contact with the inner wall of the wire clamp 25. The first ball joint on the inner wall of the wrapping rod 20 is connected to the nano-anti-aging rod 24, and the other end of the nano-anti-aging rod 24 is connected to the wire through the wire clamp 25. When the wire changes position due to factors such as line vibration and thermal expansion and contraction, the rotation of the wrapping rod 20 and the multi-angle movement of the first ball joint 23 allow the wire clamp 25 to flexibly follow the change in wire position, avoiding stress concentration at the connection point and ensuring a stable connection between the device and the wire. The nano-anti-aging rod 24 is made of nanomaterials, which can effectively resist external erosion and slow down the aging rate of materials when subjected to harsh environmental factors such as strong winds, acid rain, and ultraviolet radiation over a long period.

[0030] The balancing device 3 includes a housing 30, inside which a counterweight 31 is disposed. The inner wall of the counterweight 31 is rotatably connected to a second ball joint 32. The outer wall of the housing 30 is symmetrically fixedly connected to the outer wall of the rod 1. The outer wall of the second ball joint 32 is arranged in a circular array along the central axis of the counterweight 31. When the conductor is subjected to external forces such as wind and vibrates or tends to dance, the counterweight 31 in the balancing device 3 will be displaced inside the housing 30. Since the inner wall of the counterweight 31 is arranged in a circular array with the second ball joint 32, when the conductor dances upward, the counterweight 31 moves downward due to inertia. At this time, the ball joint drives the circular rod to rotate on the inner wall of the counterweight 31, and the compression spring 35 is stretched, generating an upward elastic force, which is opposite to the direction of the conductor's dance, thereby playing a suppressive role, improving the ability of the transmission line to resist severe weather conditions, and ensuring the safety of power transmission.

[0031] A compression spring 35 is fixedly connected to the outer wall of the second ball joint 32 via a round rod. A slide cylinder 33 is fixedly connected to the end of the compression spring 35 away from the round rod. A universal joint 34 is rotatably connected to the end of the slide cylinder 33 away from the second ball joint 32. The universal joint 34 is rotatably connected to the inner wall of the housing 30. The inner wall of the slide cylinder 33 is slidably connected to the round rod fixedly connected to the outer wall of the ball joint. The universal joint 34 rotatably connected to the end of the slide cylinder 33 away from the ball joint allows the counterweight 31 to rotate freely in the face of strong winds at multiple angles, adapting to the complex motion of the conductor. Whether the conductor swings horizontally, undulates vertically, or undergoes torsional motion, the ball joint and universal joint 34 allow for flexible adjustment of all parts of the device, maintaining a stable connection and effective anti-galloping function, enhancing the adaptability and stability of the device under different working conditions.

[0032] In use, this utility model mainly consists of a rod body 1, a connecting device 2, and a balancing device 3. The various parts cooperate with each other to achieve a flexible and stable connection with the conductor, excellent anti-aging performance, and efficient anti-galling function.

[0033] During installation, the staff aligns the wrapping rod 20 in the connecting device 2 with the outer wall of the rod body 1, and then pulls the round rod outside the buckle 22. During this process, the round rod slides on the inner wall of the buckle 22. The connecting device 2 is rotated. Since the outer wall of the buckle 22 is symmetrically fixedly connected to the outer wall of the rod body 1, the outer wall of the wrapping rod 20 is symmetrically fixedly connected to the locking ring 21. Then, during the sliding process of the buckle 22 and the locking ring 21, the sliding rod can be released until the elastic force of the compression spring 35 pushes the sliding rod to slide on the inner wall of the locking ring 21. When the collision sound produced by the sliding rod and the inner wall of the locking ring 21 is heard, the elastic force of the compression spring 35 continues to act to ensure that the buckle 22 and the locking ring 21 are tightly connected and will not be accidentally released due to vibration or other reasons.

[0034] The first ball joint on the inner wall of the wrapping rod 20 is connected to the nano anti-aging rod 24, and the other end of the nano anti-aging rod 24 is connected to the conductor through the wire clamp 25. When the conductor changes position due to factors such as line vibration and thermal expansion and contraction, the rotation of the wrapping rod 20 and the multi-angle movement of the first ball joint 23 allow the wire clamp 25 to flexibly follow the change in conductor position, avoiding stress concentration at the connection point and ensuring that the device and the conductor always maintain a stable connection. The nano anti-aging rod 24 is made of nanomaterials, which can effectively resist external erosion and slow down the aging rate of materials when subjected to harsh environmental factors such as strong winds, acid rain, and ultraviolet radiation for a long time.

[0035] When the conductor is subjected to external forces such as wind and vibrates or tends to gallop, the counterweight 31 in the balancing device 3 will be displaced inside the housing 30. Since the inner wall of the counterweight 31 has a second ball joint 32 arranged in a circumferential array, when the conductor gallops upward, the counterweight 31 moves downward due to inertia. At this time, the ball joint drives the round rod to rotate on the inner wall of the counterweight 31, and the compression spring 35 is stretched, generating an upward elastic force, which is opposite to the direction of the conductor's galloping, thereby playing a suppressive role, improving the transmission line's ability to withstand severe weather conditions, and ensuring the safety of power transmission.

[0036] The universal joint 34, rotatably connected to the end of the slide cylinder 33 away from the ball joint, allows the counterweight 31 to rotate freely when encountering strong winds at multiple angles, adapting to the complex motion of the conductor. Whether the conductor swings horizontally, undulates vertically, or undergoes torsional motion, the ball joint and universal joint 34 enable the various parts of the device to adjust flexibly, maintaining a stable connection and effective anti-galloping function, thus enhancing the adaptability and stability of the device under different working conditions.
