Description

Technical Field

[0001] This utility model relates to the field of power transmission line vibration suppression technology, and more specifically, to a vibration suppression device for high-voltage transmission towers in the event of wind. Background Technology

[0002] High-voltage transmission lines are exposed to the natural environment for extended periods, making them susceptible to fatigue and strand breakage due to light wind vibrations. Traditional vibration damping devices (such as vibration dampers and damping wires) have significant installation drawbacks: they require pre-installation during line erection or subsequent shutdown for construction; the installation process necessitates disassembling bolts or using specialized tools for fixing, making high-altitude operations difficult and time-consuming; later installations rely on line shutdown, affecting the stability of the power grid; and the installation location is prone to misalignment, leading to a decrease in vibration damping effectiveness. Current technology lacks a vibration damping device that can be quickly installed and precisely locked while energized, necessitating the design of a novel device to address these installation inconveniences. Utility Model Content

[0003] Therefore, this utility model embodiment provides a vibration suppression device for high-voltage transmission towers in the event of wind, making the installation of the vibration suppression device more convenient.

[0004] To address the aforementioned problems, this utility model provides a vibration damping device for high-voltage transmission towers, characterized by comprising: a first housing assembly; a second housing assembly rotatably connected to the first housing assembly, wherein the second housing assembly and the first housing assembly, after rotation, form a receiving space for accommodating the transmission line; the first housing assembly and the second housing assembly also have multiple through holes; a first locking assembly disposed on the first housing assembly; and a second locking assembly disposed on the second housing assembly; wherein, after the first housing assembly and the second housing assembly rotate to form the receiving space, the first locking assembly and the second locking assembly are connected and locked, thereby fixing the first housing assembly and the second housing assembly.

[0005] Compared with existing technologies, the technical advantages achieved by this solution are as follows: The rotating hinge design of the first and second housing components allows the device to open and close quickly, forming a closed enclosure to contain the transmission line, while the through-hole group facilitates fluid dissipation of vibration energy. The interlocking mechanism of the locking components automatically fixes the two housings upon closing, completely replacing traditional bolt fastening methods. This structure allows for single-handed operation without tools, enabling rapid installation and significantly reducing the risks of high-altitude work and the cost of power outage construction. It is particularly suitable for live-line vibration suppression retrofitting projects on ultra-high voltage lines, solving a long-standing bottleneck in installation efficiency within the industry.

[0006] In one embodiment of this utility model, the first locking component is an elastic element; the second housing component is provided with a mating hole for elastically engaging with the elastic element.

[0007] Compared to existing technologies, this technical solution achieves the following advantages: the elastic engagement design between the elastic element and the mating hole creates a transient locking function, while continuous clamping force is generated through material deformation. Compared to threaded fastening, this structure eliminates the dependence of the tightening action on operating space, and can still achieve locking with a single press even in strong winds. Furthermore, the elastic engagement method makes installation more efficient and simpler, requiring only a press to install, making it more efficient than other traditional installation methods.

[0008] In one embodiment of this utility model, the elastic element further includes a guide portion, which extends in a direction away from the receiving space.

[0009] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting the guide part, it is more convenient and faster to assemble the elastic element with the second locking component. Through the guidance of the guide part, the elastic element can better enter the mating hole, making the installation more labor-saving and convenient.

[0010] In one embodiment of this utility model, the first locking component is provided with a first mating part; the second locking component is provided with a second mating part, which is used to penetrate and engage with the first mating part, so that the first locking component and the second locking component are fixed.

[0011] Compared with existing technologies, the technical advantages achieved by this solution are as follows: The penetrating interlocking of the first and second mating parts forms a rigid mechanical fixation, which is more resistant to strong wind impacts than a purely elastic lock. The penetrating structure ensures a uniform distribution of locking force, avoiding shell cracking caused by localized stress concentration, making it particularly suitable for long-term vibration suppression requirements in harsh working conditions such as large spans and heavy icing areas. Furthermore, the penetrating fit simplifies the fixing process and structure, making installation easier and faster.

[0012] In one embodiment of this utility model, the second locking component further includes: a first fixing member, the first fixing member having a receiving groove, a second mating part slidingly engaging with the receiving groove, and the second mating part being able to slide along the receiving groove; and a limiting part, the limiting part being disposed in the receiving groove, the limiting part being used to engage with the second mating part, thereby restricting the sliding position of the second mating part.

[0013] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting the sliding fit between the second mating part and the receiving groove, it is more convenient and faster to operate the second mating part without the need for additional tools. At the same time, through the cooperation of the limiting part and the second mating part, the second mating part can be restricted when sliding, and can slide to the position that needs to be slid, without sliding too far and thus disengaging from the equipment, thereby improving the convenience of operation and the efficiency of installation.

[0014] In one embodiment of this utility model, the second mating part is provided with a limiting block that protrudes toward the limiting part, and the limiting block and the limiting part are embedded and mated.

[0015] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting a limiting block that protrudes towards the limiting part, the second mating part can be better restricted when sliding, without the need for an additional complex structure, making it more convenient and quick to fix the second mating part, thereby making the locking efficiency higher, and thus making the overall installation efficiency higher.

[0016] In one embodiment of this utility model, the high-voltage transmission tower micro-wind vibration suppression device further includes: multiple suppression components, which are disposed on the first housing component and the second housing component, and are used to suppress the transmission line.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: multiple pressing components form a distributed flexible constraint on the conductor, suppressing aerobatic vibrations through multi-point energy dissipation. Compared with traditional single-point rigid fixing, this design avoids stress concentration damage to the conductor surface, while uniformly dispersing vibration energy and improving vibration suppression efficiency, making it particularly suitable for long-span transmission line sections.

[0018] In one embodiment of this utility model, each pressing assembly further includes: a pressing plate, which adheres to the surface of the transmission line after the first housing assembly and the second housing assembly are closed; and an elastic connector for connecting the pressing plate to the first housing assembly or the second housing assembly.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: the elastic connector allows the pressing plate to dynamically conform to the surface of the conductor, continuously providing adaptive clamping force during vibration. Compared with fixed clamping blocks, this structure compensates for manufacturing errors in conductor diameter and operational creep, avoids gaps that may develop after long-term use leading to vibration damping failure, and reduces maintenance frequency.

[0020] In one embodiment of this utility model, the shape of the pressing plate is adapted to the shape of the power transmission line.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: the curvature matching design of the pressing plate and the conductor contour maximizes the contact area. It eliminates the problem of local extrusion deformation of cables caused by traditional flat pressing plates, evenly distributes compressive stress, prevents wear and breakage of aluminum strands, extends the service life of the conductor, and maintains stable conductivity.

[0022] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0023] (1) The rotating hinge design of the first and second housing components allows the device to be quickly opened and closed to form a closed enclosure space for the transmission line, which, together with the through-hole group, enables the fluid dissipation of vibration energy; the interlocking mechanism of the locking component automatically fixes the two housings at the moment of closing, completely replacing the traditional bolt fastening method. This structure allows operators to operate with one hand without tools, quickly complete the installation, significantly reduce the risk of high-altitude operations and the cost of power outage construction, and is especially suitable for live vibration suppression retrofitting of ultra-high voltage lines, solving the long-standing bottleneck problem of installation efficiency in the industry;

[0024] (2) The penetrating interlock between the first and second mating parts forms a mechanically rigid fixation, which is more resistant to strong wind impact than a purely elastic lock. The penetrating structure ensures that the locking force is evenly distributed, avoiding shell cracking caused by local stress concentration, and is especially suitable for long-term vibration suppression requirements in harsh working conditions such as large spans and heavy icing areas. At the same time, the fixation method through the penetrating fit makes the fixation method simpler and the structure simpler, thus making the installation more convenient and quick.

[0025] (3) Multiple compression components form a distributed flexible constraint on the conductor, suppressing wind vibration through multi-point energy dissipation. Compared with the traditional single-point rigid fixation, this design avoids stress concentration damage to the conductor surface, while uniformly dispersing vibration energy and improving vibration suppression efficiency, which is especially suitable for long-span transmission line sections.

[0033] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] [First Embodiment]

[0035] See Figures 1-4 This utility model provides a vibration damping device 100 for high-voltage transmission towers, characterized in that it includes: a first housing assembly 110; a second housing assembly 120, the second housing assembly 120 being rotatably connected to the first housing assembly 110, and the second housing assembly 120 and the first housing assembly 110 forming a receiving space 130 after rotation, the receiving space 130 being used to accommodate the transmission line; the first housing assembly 110 and the second housing assembly 120 are also provided with a plurality of through holes 140; a first locking assembly 150, the first locking assembly 150 being disposed on the first housing assembly 110; and a second locking assembly 160, the second locking assembly 160 being disposed on the second housing assembly 120; wherein, after the first housing assembly 110 and the second housing assembly 120 rotate to form the receiving space 130, the first locking assembly 150 and the second locking assembly 160 are connected and locked, thereby fixing the first housing assembly 110 and the second housing assembly 120.

[0036] Specifically, in actual use, the device is first brought to the line that needs to be suppressed, and then installed at a selected location. The first housing assembly 110 and the second housing assembly 120 are flipped open, the power transmission line is placed inside either of them, and then the first housing assembly 110 and the second housing assembly 120 are flipped open to cover the power transmission line, so that the power transmission line is completely contained in the receiving space 130.

[0037] Furthermore, at this time, the elastic element on the first housing assembly 110 is engaged in the mating hole 121 provided on the second housing assembly 120, and the elastic element extends out of the mating hole 121 to the outside. A first mating part 152 is provided on the extended part, which can be a slot. Then, by pushing the second mating part 161, the second mating part 161 passes through the slot, so that the second mating part 161 can engage the first mating part 152, thereby making the elastic element engage and fixed.

[0038] Specifically, when the second mating part 161 is pushed, the limiting block 164 slides within the limiting part 163, where the limiting part 163 can be a groove. The limiting block 164 slides within the groove until it slides to the edge of the groove and fits. At this point, the second mating part 161 completely penetrates the first mating part 152, and the fixing is completed.

[0039] Preferably, the rotating hinge design of the first housing assembly 110 and the second housing assembly 120 allows the device to be quickly opened and closed to form a closed receiving space 130 that encloses the transmission line. This, combined with the group of through holes 140, enables fluid dissipation of vibration energy. The interlocking mechanism of the locking assembly automatically fixes the two housings upon closing, completely replacing the traditional bolt fastening method. This structure allows for one-handed operation without tools, enabling rapid installation and significantly reducing the risks of high-altitude operations and the cost of power outage construction. It is particularly suitable for live-line vibration suppression retrofitting projects on ultra-high voltage lines, solving the long-standing bottleneck of installation efficiency in the industry.

[0043] Preferably, by providing the guide portion 151, the elastic element can be more conveniently and quickly assembled with the second locking component 160. The guide portion 151 guides the elastic element to better enter the mating hole 121, making the installation more labor-saving and convenient.

[0044] Specifically, the first locking component 150 is provided with a first mating part 152; the second locking component 160 is provided with a second mating part 161, which is used to penetrate and engage with the first mating part 152, so that the first locking component 150 and the second locking component 160 are fixed.

[0047] Preferably, by setting the sliding fit between the second mating part 161 and the receiving groove, it is more convenient and faster to operate the second mating part 161 without the need for additional tools. At the same time, through the cooperation of the limiting part 163 and the second mating part 161, the second mating part 161 can be restricted when sliding, and can slide to the position that needs to be slid, without sliding too far and thus disengaging from the equipment, thereby improving the convenience of operation and the efficiency of installation.

[0048] Specifically, the second mating part 161 is provided with a limiting block 164 that protrudes toward the limiting part 163, and the limiting block 164 and the limiting part 163 are embedded and mated.

[0053] Specifically, the elastic connector 172 can be a spring, and a protective layer can be provided on the side of the pressing plate 171 facing the line to prevent damage to the line.

[0054] Preferably, the elastic connector 172 allows the pressing plate 171 to dynamically conform to the surface of the conductor, continuously providing adaptive clamping force during vibration. Compared to a fixed clamping block, this structure compensates for manufacturing errors in conductor diameter and operational creep, avoids gaps that may develop after long-term use leading to vibration damping failure, and reduces maintenance frequency.
