Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to an anti-vibration device for overhead lines. Background Technology

[0002] With the rapid development of the power industry and the continuous growth of social electricity demand, the coverage of power grids is constantly expanding, and the network structure is becoming increasingly complex. Against this backdrop, overhead transmission lines, as a key infrastructure for power transmission, are being laid at an ever-increasing density.

[0003] However, in some areas, especially urban centers, old urban areas, and areas with complex terrain, newly built or renovated overhead lines often face insufficient spacing due to factors such as limited land resources and limited space in existing line corridors. This insufficient spacing poses a potential threat to the safe operation of the lines even under normal weather conditions, and the problem becomes more pronounced during periods of strong winds or severe weather such as heavy rain, icing, and lightning. Strong winds and other external forces can easily cause significant oscillations, galloping, or swaying of the lines, leading to collisions between the three-phase conductors or accidental short circuits with neighboring lines, tower components, and surrounding obstacles. Such faults not only cause large-scale power outages, disrupting social production and daily life, but also severely impact the safe and stable operation of the power grid, potentially leading to major safety accidents such as equipment damage and personal injury. Furthermore, after the lines are laid, the surrounding environment is not static. Subsequent additions to the line network, the construction of new buildings or structures, and the growth of trees further compress the safety distance of the existing lines, continuously increasing the risk of collisions or accidental short circuits between lines.

[0004] Therefore, effectively solving the problems of line collisions and accidental contact caused by insufficient line spacing and environmental changes has become a key technical challenge that urgently needs to be addressed to ensure the safe operation of overhead transmission lines and improve the overall reliability of the power grid.

[0068] This application discloses an anti-vibration device for overhead lines.

[0069] Please see Figure 1 One embodiment of the overhead line anti-vibration device provided in this application includes:

[0070] Insulating sleeve 1, vibration damping mechanism 2, fixing mechanism 3, and adjusting mechanism 4.

[0071] The vibration damping mechanism 2 is installed in the insulating sleeve 1 and includes two insulating telescopic rods 211. The two insulating telescopic rods 211 are slidably inserted into the insulating sleeve 1 through both ends. A composite insulator 212 is fixedly connected to one end of the two insulating telescopic rods 211 that is far apart from each other. The composite insulator 212 is usually composed of a core rod, a shed sheath, and hardware. The core rod is made of high-strength glass fiber or synthetic resin material, which has good tensile strength and weather resistance. The shed sheath is made of silicone rubber and other materials, which has excellent water repellency and anti-aging properties.

[0072] Two composite insulators 212 are each connected to an elastic hoop 216 at their far ends for the cable 217 to pass through; a fixing mechanism 3 is connected to the elastic hoop 216 and is used to drive the elastic hoop 216 to tighten the cable 217 passing through; an adjusting mechanism 4 is installed on the insulating sleeve 1 and is used to lock the connection between the insulating telescopic rod 211 and the insulating sleeve 1.

[0073] By integrating composite insulator 212 and insulating telescopic rod 211 to form a stable fixing system, composite insulator 212 ensures the electrical safety of the line with its high strength and excellent insulation performance, while insulating telescopic rod 211 can be flexibly adjusted to adapt to different line spacing and tension changes, effectively reducing conductor vibration amplitude.

[0074] The overhead line anti-vibration device designed in this application has the following beneficial effects:

[0075] By integrating composite insulators 212 and insulated telescopic rods 211, the overhead lines are dynamically fixed, effectively reducing line oscillations, avoiding collision accidents, ensuring the safe operation of overhead transmission lines, and improving the overall reliability of the power grid.

[0076] The above is Embodiment 1 of the overhead line anti-vibration device provided in this application. The following is Embodiment 2 of the overhead line anti-vibration device provided in this application. Please refer to the following for details. Figures 1 to 6 .

[0077] Based on the solution of Embodiment 1 above:

[0078] Furthermore, such as Figure 5 As shown, each of the two insulating telescopic rods 211 has a U-shaped frame 213 fixedly connected to one end of each other; each of the two U-shaped frames 213 has a detachable insert rod 214; each of the two detachable insert rods 214 has a connecting sleeve 215 fitted on its outer wall; and each of the two connecting sleeves 215 has a detachable end of each other fixedly connected to an elastic hoop 216.

[0079] The combination of the U-shaped frame 213 with the detachable insert rod 214 and connecting sleeve 215 makes the connection between the elastic hoop 216 and the insulated telescopic rod 211 more flexible and easier to install and disassemble. If the elastic hoop 216 is damaged or needs adjustment, workers can easily remove the connecting sleeve 215 from the detachable insert rod 214 to replace or repair the elastic hoop 216 without having to disassemble and replace the entire device on a large scale, thus reducing maintenance costs and time.

[0080] Furthermore, such as Figure 1 As shown, for the design of the fixing mechanism 3, the fixing mechanism 3 includes two fixing components 31.

[0081] The two fixing components 31 are respectively connected to the two elastic hoops 216.

[0082] The fixing component 31 includes a first fixing block 311, a second fixing block 313, and a fastener 315; the first fixing block 311 is fixed to one end of the outer wall of the elastic hoop 216; the second fixing block 313 is fixed to the other end of the outer wall of the elastic hoop 216; the fastener 315 connects the first fixing block 311 and the second fixing block 313, and is used to drive the first fixing block 311 and the second fixing block 313 to move closer to each other, so that the elastic hoop 216 tightens the cable 217 passing through.

[0083] The design of this fixing component 31 ensures reliable fixation of the elastic clamp 216 to the cable 217. When installing the cable 217, the operator can first pass the cable 217 through the elastic clamp 216, and then operate the fastener 315 to bring the first fixing block 311 and the second fixing block 313 closer together, gradually reducing the inner diameter of the elastic clamp 216 until it tightly clamps the cable 217. This fixing method is not only secure but also adjustable according to the thickness of the cable 217, making it highly versatile.

[0084] Furthermore, such as Figure 5 As shown, the first fixing block 311 has a threaded hole 312; the second fixing block 313 has a round hole 314; the fastener 315 is a screw, and a nut 316 is connected to its outer wall; the fastener 315 passes through the round hole 314 and is threadedly connected to the threaded hole 312; the nut 316 can contact and abut against the second fixing block 313. One end of the screw extends out of the round hole 314 and is provided with a first mating part 317.

[0085] The above design achieves a stable connection through the collaboration of multiple components. After the fastener 315 passes through the circular hole 314, it is double-fixed by the nut 316, which is threaded into the threaded hole 312 and whose top abuts against the second fixing block 313. A first mating part 317 is provided at one end of the fastener 315 extending out of the circular hole 314. This not only ensures the stability of the connection between the fixing component 31 and the elastic hoop 216, but also facilitates subsequent disassembly and assembly operations through the first mating part 317, effectively improving the assembly convenience and connection reliability of the overall structure.

[0086] Furthermore, such as Figure 1 As shown, it also includes two disassembly components 32; the two disassembly components 32 are respectively connected to two fixing components 31, and are used to drive the fixing components 31 to release the elastic hoop 216 from the cable 217 passing through.

[0087] When the vibration damping device needs maintenance or replacement, the disassembly component 32 plays a crucial role. By operating the disassembly component 32, the fixing component 31 can be moved, easily releasing the elastic clamp 216 from the cable 217. This allows the cable 217 to be quickly removed from the elastic clamp 216 without damaging other parts of the device, significantly improving the efficiency of maintenance and replacement.

[0088] Furthermore, the disassembly assembly 32 includes a horn head 321 into which one end of the fastener 315 extends out of the circular hole 314; one end of the fastener 315 is provided with a first mating part 317; the inner bottom of the horn head 321 is provided with a second mating part 322, which can be torsionally connected with the first mating part 317; an electrical insulating rod 323 is fixedly connected to the bottom of the horn head 321. The first mating part 317 is a hexagonal head; the second mating part 322 is a hexagonal groove.

[0089] By setting a flared head 321 at the bottom of the fastener 315, and opening a second mating part 322 (hexagonal groove) on the inner wall of the bottom of the flared head 321 to match the first mating part 317 (hexagonal head) of the fastener 315, and fixing an electrical insulating rod 323 to the bottom of the flared head 321, the fastener 315 can be quickly fitted through the precise fit of the hexagonal groove and the hexagonal head. The electrical insulating rod 323 ensures the insulation safety during operation. The extension of the insulating rod also facilitates the rotation of the fastener 315. This greatly improves the convenience, safety and efficiency of the disassembly and assembly of the fixing component 31, and further optimizes the user experience of the overall technical solution.

[0090] Furthermore, such as Figure 1 As shown, the adjustment mechanism 4 includes a limiting component 41 and an adjustment component 42; the limiting component 41 is used to allow the insulating telescopic rod 211 and the insulating sleeve 1 to slide axially but be fixedly connected circumferentially; the adjustment component 42 connects the insulating sleeve 1 and the insulating telescopic rod 211 and is used to lock the connection between the insulating telescopic rod 211 and the insulating sleeve 1.

[0091] The design of the limiting component 41 ensures the smooth sliding and stability of the insulating telescopic rod 211 within the insulating sleeve 1. The axial sliding connection allows the insulating telescopic rod 211 to be adjusted in length and width according to the actual conditions of the line to adapt to different line spacing requirements. The circumferential fixed connection prevents unnecessary rotation of the insulating telescopic rod 211 during operation, ensuring the structural stability and operational reliability of the entire anti-vibration device.

[0092] The adjusting component 42 provides an effective means of locking the connection between the insulating telescopic rod 211 and the insulating sleeve 1. Through the adjusting component 42, the position of the insulating telescopic rod 211 can be precisely locked according to actual needs. Operators can flexibly adjust the extension length of the insulating telescopic rod 211 by operating the adjusting component 42 and then lock it to adapt to new working conditions.

[0093] Furthermore, such as Figure 7 As shown, the design of the limiting component 41 includes a groove 411 formed on the inner wall of the insulating sleeve 1; the outer walls of the two insulating telescopic rods 211 are fixedly connected with sliders 412 that extend into the groove 411 and are slidably connected to the groove 411.

[0094] By creating a groove 411 on the inner wall of the insulating sleeve 1 and fixing sliders 412 to the outer walls of both insulating telescopic rods 211, the sliders 412 extend into the groove 411 on both sides and form a sliding fit (it can be understood that the outer wall of the insulating telescopic rod 211 is fixedly connected to the sliders 412; at least one part of the sliders 412 extends into the groove 411 and is slidably connected to the groove 411). This not only provides precise guidance for the telescopic movement of the insulating telescopic rods 211, preventing them from deviating or wobbling during movement, but also limits the travel of the insulating telescopic rods 211 through the fit between the grooves 411 and the sliders 412, preventing them from detaching from the insulating sleeve 1. This effectively ensures the stability and reliability of the overall structure's movement and provides strong support for the smooth implementation of subsequent fixing, disassembly, and other operations.

[0095] Furthermore, regarding the design of the adjustment component 42, the adjustment component 42 includes several insertion holes 421 formed on the outer walls of the two insulating telescopic rods 211; two mounting seats 422 are fixedly connected to the outer wall of the insulating sleeve 1; a pressing plate 423 is rotatably connected to each of the two mounting seats 422; an insertion rod 424 is fixedly connected to one end of each of the two pressing plates 423; both insertion rods 424 penetrate the insulating sleeve 1 and are slidably connected to the insulating sleeve 1; the top ends of both insertion rods 424 extend into the corresponding two insertion holes 421; elastic elements are provided on each of the two mounting seats 422; the two elastic elements are respectively connected to the other ends of the two pressing plates 423, and are used to provide an elastic force for the pressing plates 423 to rotate in the direction in which the insertion rods 424 are inserted into the corresponding insertion holes 421.

[0096] The elastic element plays a crucial role here, ensuring that the insertion rod 424 can be stably inserted into the socket 421, thus locking the connection between the insulating telescopic rod 211 and the insulating sleeve 1. When the position of the insulating telescopic rod 211 needs to be adjusted, the operator simply presses the other end of the pressing plate 423 to overcome the elastic force of the elastic element, causing the insertion rod 424 to be pulled out of the socket 421. At this time, the insulating telescopic rod 211 can slide freely axially within the insulating sleeve 1, achieving telescopic adjustment. After adjusting to the appropriate position, releasing the pressing plate 423 causes the elastic element to recover its elastic deformation, rotating the pressing plate 423 in the direction that the insertion rod 424 should be inserted into the corresponding socket 421, allowing the insertion rod 424 to be re-inserted into the corresponding socket 421, thereby re-locking the connection between the insulating telescopic rod 211 and the insulating sleeve 1. This adjustment method is simple and flexible to operate, and can quickly adapt to different line spacing and tension changes.

[0097] Furthermore, the design of multiple insertion holes 421 provides more adjustment options for the insulating telescopic rod 211, allowing for precise positioning according to actual needs. The mounting base 422 provides stable rotational support for the pressing plate 423, ensuring smooth rotation during operation. The sliding connection between the insertion rod 424 and the insulating sleeve 1 ensures smooth insertion and withdrawal of the insertion rod 424 from the insertion holes 421, further improving the working efficiency and reliability of the adjustment assembly 42. The overall design of the adjustment assembly 42 enables the overhead line anti-vibration device to be flexibly adjusted according to different operating conditions, effectively enhancing the adaptability and practicality of the device and providing strong protection for the safe and stable operation of overhead transmission lines.

[0098] like Figure 8 As shown, the elastic element design includes a connecting telescopic rod 425 and a spring 426; the two ends of the connecting telescopic rod 425 are respectively connected to a pressing plate 423 and a mounting base 422; the spring 426 is wound around the connecting telescopic rod 425, with one end contacting and abutting against the mounting base 422 and the other end contacting and abutting against the pressing plate 423.

[0099] By fixing telescopic rods 425 to the bottom of the two mounting bases 422, the end of the telescopic rod away from the mounting base 422 is fixedly connected to the pressing plate 423. At the same time, springs 426, which are fixed to the mounting base 422 and the pressing plate 423 respectively, are wound around the outer wall of the connecting telescopic rods 425. The connecting telescopic rods 425 provide precise guidance for the extension and contraction of the springs 426, preventing the springs 426 from shifting or twisting and affecting the elastic effect. The elastic force of the springs 426 provides continuous reset support for the pressing plate 423, ensuring that the insertion rod 424 can be stably engaged in the insertion hole 421, effectively preventing the adjustment component 42 from loosening.

[0100] When the pressing plate 423 is pressed, the spring 426 is compressed synchronously with the telescopic rod. After being released, it can quickly reset and reset the insertion rod 424, which not only ensures the ease of operation of the adjustment component 42, but also improves the connection stability and service life of the overall structure.

[0101] The above provides a detailed description of the overhead line anti-vibration device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
