Description
Technical Field
[0001] This application relates to the field of power transmission facilities technology, and in particular to a wind-resistant reinforcement device for power transmission and transformation towers. Background Technology
[0002] Transmission towers are critical supporting structures for power grids. Long-term exposure to the elements makes them susceptible to wind-induced vibration, buckling of members, and even complete collapse under extreme wind loads such as typhoons and strong convection. Wind disasters have become a major threat to power transmission safety. Current wind-resistant reinforcement methods primarily involve adding windbreaks or guy cables. However, current technologies still have the following problems: 1. The existing cables lack buffers at both ends, making them prone to vibration and impact under strong winds. This directly causes stress concentration and fatigue damage at the cable connection points, potentially leading to connection point detachment and cable breakage. Furthermore, the cables lack vibration resistance and cannot dissipate vibration energy under strong winds. When the transmission tower is subjected to wind load impact, the cables directly and rigidly transfer the load to the tower body, causing localized stress concentration and member buckling. In addition, the connection between the cable ends and the tower frame is unstable, resulting in slippage. During slippage, the direction of force on the cables shifts in real time, failing to form a stable constraint and making it difficult to continuously share the wind load, thus significantly reducing the wind-resistant reinforcement effect.
[0003] 2. Traditional enclosed enclosures lack ventilation and pressure relief structures, making them unable to adapt to changes in wind force. Under extreme strong winds, the overall force of the enclosure becomes unbalanced, which can easily lead to local deformation and cracking. Fallen parts may also impact the tower, posing additional safety risks. Without enclosures, strong winds carrying debris can easily and continuously impact the cables, exacerbating wear on the connection points between the cables and the tower. Summary of the Invention
[0004] To overcome the shortcomings of existing cables, which lack buffering at both ends, are prone to vibration and impact under strong winds, directly causing stress concentration and fatigue damage at cable connection points, and even leading to connection point detachment and cable breakage, this invention aims to provide a wind-resistant reinforcement device for transmission towers to address these deficiencies. This device addresses the shortcomings of traditional enclosed barriers lacking ventilation and pressure relief structures, making them unable to adapt to wind changes. Under extreme strong winds, the barriers experience overall stress imbalance, leading to localized deformation and cracking. Furthermore, the lack of vibration resistance means that cables cannot dissipate vibration energy under strong winds. When transmission towers are subjected to wind loads, the cables directly and rigidly transfer the load to the tower body, causing localized stress concentration and member buckling.

[0015] The technical solution provided in this application has at least the following technical effects or advantages: 1. By adopting cable assemblies, the existing problems of lacking buffers at both ends of cables, making them prone to vibration and impact under strong winds, directly causing stress concentration and fatigue damage at cable connection points, and even leading to connection point detachment and cable breakage, are effectively solved. Furthermore, cables lack vibration resistance and cannot dissipate vibration energy under strong winds. When the transmission tower is subjected to wind load impact, the cables directly and rigidly transfer the load to the tower body, causing localized stress concentration and member buckling. In addition, the connection between the cable ends and the tower frame is unstable, resulting in slippage. During slippage, the force direction of the cable shifts in real time, failing to form a stable constraint and making it difficult to continuously share the wind load. This significantly improves the wind resistance and reinforcement effect. Significant attenuation: This invention utilizes the buffering effect of the cable assembly to absorb wind vibration energy, attenuate vibration amplitude, reduce instantaneous impact loads, and protect cable connection nodes. This extends the service life of the cables, improves the overall structural wind resistance stability, avoids resonance and fatigue damage, and also has an anti-vibration effect, effectively dissipating wind-induced vibration energy, preventing the load from being rigidly transmitted directly to the tower body, and eliminating member buckling. In addition, the cable ends can be stably connected to the tower frame, eliminating slippage at the connection point, ensuring that the cable force direction remains constant, forming a continuously reliable flexible constraint system that can stably share wind loads over a long period of time, and can provide timely warnings when deviation occurs on the frame, facilitating rapid response.
[0016] 2. Due to the use of windproof components, the traditional enclosed enclosure lacks ventilation and pressure relief structures, making it unable to adapt to changes in wind force. Under extreme strong winds, the overall force of the enclosure becomes unbalanced, easily leading to local deformation and cracking. Fallen parts may also impact the tower, posing additional safety risks. Without enclosures, strong winds carrying debris can easily and continuously impact the cables, accelerating wear on the connection points between the cables and the tower. This invention uses windproof components to prevent strong winds from carrying debris that impacts the cables, reducing additional risks. At the same time, the enclosure can autonomously ventilate a small area according to the wind pressure during strong winds, effectively reducing the wind pressure on the enclosure panels, preventing wind pressure buildup from causing damage to the panels, preventing fallen parts from damaging the tower, and increasing the service life of the enclosure.

[0019] For cables without buffers at both ends, they are prone to vibration and impact under strong winds. This invention addresses this by using cable components that provide buffering, absorbing wind vibration energy, attenuating vibration amplitude, reducing instantaneous impact loads, and protecting cable connection nodes. This extends the cable's service life, improves the overall structure's wind resistance stability, and prevents resonance and fatigue damage. For traditional enclosed enclosures without ventilation and pressure relief structures that cannot adapt to wind changes, this invention uses windproof components to prevent strong winds from carrying debris that could impact the cables, reducing additional risks. At the same time, the enclosure can autonomously ventilate a small area based on wind pressure during strong winds.
[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1
[0021] Please see Figure 1As shown, a wind-resistant reinforcement device for power transmission towers includes a tower body 1, which is constructed of a steel frame. The tower body 1 is welded and fixedly connected to a base 2 with bolts. The base 2 is fixedly connected to the ground with bolts and concrete pouring. The base 2 is fixedly connected to the bottom of the tower body 1. Four cable assemblies 3 are provided on the outer surface of the tower body 1, located at four different positions on the tower body 1. A windproof assembly 4 is fixedly installed on the outer surface of the base 2. The cable assemblies 3 and the windproof assembly 4 are used to protect the tower body 1. The cable assemblies 3 have elastic deformation and energy dissipation capabilities, which can absorb wind-induced vibration energy, prevent the rigid transmission of wind load to the tower body of the tower body 1, and alleviate the problems of stress concentration and member buckling in the tower body. The windproof assembly 4 can protect the bottom of the tower body 1 and the cable assemblies 3.
[0022] Please see Figure 2 As shown, the cable assembly 3 includes a cable chain 31. A first damping mechanism 32 is provided at one end of the cable chain 31. A connecting plate 33 is provided at the bottom end of the first damping mechanism 32. A first threaded rod 34 is rotatably connected to the inner cavity of the connecting plate 33. Second damping mechanisms 35 are provided at both ends of the first threaded rod 34. Buffer mechanisms 36 are provided at both ends of the cable chain 31. A clamping mechanism 37 is provided at the end of the cable chain 31 away from the first damping mechanism 32. The cable chain 31 can provide stable flexible constraints on the main body 1 of the power tower, continuously sharing the lateral wind load and limiting the horizontal sway and severe vibration of the tower. The first damping mechanism 32 is used to dampen the cable chain 31 in the horizontal direction. The second damping mechanism 35... The first threaded rod 34 is used to dampen the cable chain 31 in the vertical direction, thereby stabilizing the force angle of the cable chain 31, ensuring that the cable chain 31 always maintains a constant tension, continuously sharing the lateral wind pressure of the tower body, reducing wear and loosening of the bottom connectors, avoiding constraint failure, extending the service life of the cable and connecting components, further suppressing the sway amplitude of the tower body, improving the stability of the entire wind-resistant cable system from the root, and ensuring the long-term safe resistance of the transmission tower against strong wind disasters. The rotation of the first threaded rod 34 can adjust the position of the first damping mechanism 32 on the connecting plate 33, keeping the cable chain 31 taut. The clamping mechanism 37 is fixed on the frame of the power tower body 1, so that the cable chain 31 and the power tower body 1 are stably connected.
[0023] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the first damping mechanism 32 includes an adjusting plate 321, with a connecting seat 322 slidably connected to the inner cavity of the adjusting plate 321. A first damper 323 is provided on the inner wall of the adjusting plate 321, and a first spring 324 is sleeved on the outer surface of the first damper 323. One end of the cable chain 31 is fixedly connected to the connecting seat 322. The adjusting plate 321 and the connecting plate 33 are slidably connected. The adjusting plate 321 and the first threaded rod 34 are connected by threads. The first damper 323 and the first spring 324 are both located between the connecting seat 322 and the inner wall of the adjusting plate 321. The bottom end of the adjusting plate 321 is slidably connected to the outer surface of the base 2. The second damping mechanism 35 includes a damping seat 351, with a slide 352 slidably connected to the inner cavity of the damping seat 351. The damping seat 351 and the slide 352 are connected to each other. A second damper 353 and a second spring 354 are provided between the inner walls of 52. The second spring 354 is sleeved on the outer surface of the second spring 354. The lower surface of the shock absorber 351 is fixedly connected to the outer surface of the base 2. The upper surface of the slide 352 is fixedly connected to the lower surface of the connecting plate 33. The buffer mechanism 36 includes a connecting leg 361. A limit ring 362 is fixedly installed in the middle part of the connecting leg 361. A groove 363 is opened on the outer surface of the limit ring 362. A buffer ring 364 is provided in the middle part of the limit ring 362. A first slide rod 365 is fixedly installed on the outer surface of the buffer ring 364. A third spring 366 is sleeved on the outer surface of the first slide rod 365. A washer 367 is slidably connected to the outer surface of the first slide rod 365. The outer surface of the connecting leg 361 is... A sloping groove 368 is provided. A connecting strip 369 is fixedly installed on the outer surface of the buffer ring 364. A first button 3610 is provided at the end of the connecting strip 369 away from the buffer ring 364. A first alarm 3611 is fixedly installed on the outer surface of the connecting strip 369. A first slide rod 365 and a slide groove 363 are slidably connected. A third spring 366 is located between the buffer ring 364 and a washer ring 367. The washer ring 367 is in close contact with the inner wall of the limiting ring 362. The first button 3610 and the first alarm 3611 are electrically connected, and pressing the first button 3610 causes the first alarm 3611 to sound an alarm. A pull chain 31 is located in the middle inner cavity of the buffer ring 364, and there is a gap between the pull chain 31 and the inner cavity of the buffer ring 364, allowing the buffer ring 364 to generate a large amplitude. When the device shakes, the first button 3610 and the inclined groove 368 are compressed. When the cable chain 31 vibrates horizontally against the connecting seat 322, the connecting seat 322 slides within the cavity of the adjusting plate 321. At this time, the connecting seat 322 and the adjusting plate 321 compress the first damper 323 and the first spring 324. The first damper 323 and the first spring 324 work together to dampen the vibration. The first spring 324, relying on its own elastic deformation, can buffer the instantaneous impact load brought by strong winds, absorb the instantaneous wind pressure impact, adapt to the small reciprocating displacement of the cable chain 31, stabilize the tension of the cable chain 31, counteract the end slippage, and prevent the rigid force from being directly transmitted to the tower body, thus playing a flexible buffering role. The first damper 323 converts the reciprocating mechanical vibration energy of the tower body and the cable into heat energy for dissipation.To suppress structural resonance and reduce vibration amplitude, the slide 352 slides within the cavity of the damping seat 351 in the vertical direction, compressing the second damper 353 and the second spring 354. The elastic force of the second spring 354 buffers the instantaneous impact load from strong winds, while the second damper 353 suppresses structural resonance. Therefore, the bottom connection point of the cable chain 31 can simultaneously achieve horizontal and vertical bidirectional vibration damping. Horizontally, it can offset the lateral wind-induced displacement of the tower body, buffer the impact of lateral wind pressure, limit the left and right sway of the tower body, and stabilize the horizontal force angle of the cable. Vertically, it can absorb vertical alternating vibration loads, release the reciprocating tension of the cable, prevent the bottom node from bearing vertical fatigue stress, improve the constraint stability of the cable chain 31, and provide comprehensive protection for the tower body and connecting components, enhancing the overall wind and earthquake resistance of the transmission tower. The buffer mechanism 36 is used to dampen the sway of the cable chain 31. The system provides cushioning. When the cable chain 31 sways, it compresses the buffer ring 364. At this time, the first slide rod 365 slides in the inner cavity of the slide groove 363, causing the buffer ring 364 to compress the third spring 366. The pad ring 367 prevents the third spring 366 and the limit ring 362 from rubbing against each other. The elasticity of the third spring 366 reduces the swaying amplitude of the buffer ring 364 and quickly returns it to its original position, thereby improving the overall stability of the cable chain 31. When the cable chain 31 sways significantly, the swaying of the buffer ring 364 causes the connecting bar 369 to move. At this time, the first button 3610 and the inclined groove 368 compress, causing the first alarm 3611 to sound an alarm. This system enables the cable chain 31 to reduce instantaneous impact loads, protect the connection nodes of the cable chain 31, extend the service life of the cable chain 31, and improve the overall structural wind resistance stability.
[0024] Please see Figure 7 , Figure 8 and Figure 9As shown, the clamping mechanism 37 includes a clamping plate 371. A connecting block 372 is fixedly installed on the outer surface of the clamping plate 371. The end of the cable chain 31 away from the connecting seat 322 is fixedly connected to the connecting block 372. A clamping arm 373 is slidably connected to the outer surface of the clamping plate 371. A second threaded rod 374 is rotatably connected to the inner cavity of the clamping plate 371. A slider 375 is slidably connected to the inner cavity of the clamping arm 373. Second slide rods 376 are fixedly installed at both ends of the slider 375. A flexible clamping block 377 is slidably connected to the inner cavity of the slider 375. A first elastic rod 378 is fixedly installed on the outer surface of the flexible clamping block 377. A fixing ring 379 is fixedly installed on the outer surface of the first elastic rod 378. A fourth spring 37 is sleeved on the outer surface of the first elastic rod 378. 10. A second alarm 3711 is fixedly installed on the outer surface of the clamping arm 373. A second button 3712 is provided on the inner wall of the clamping arm 373. There are two connecting legs 361 on the cable chain 31. One connecting leg 361 is fixedly connected to the outer surface of the adjusting plate 321, and the other connecting leg 361 is fixedly connected to the outer surface of the clamping plate 371. The second threaded rod 374 is threadedly connected to the clamping arm 373, and the threads at both ends of the second threaded rod 374 are opposite in direction. The clamping arm 373 is clamped and fixed to the frame on the outer surface of the power tower body 1. The second slide rod 376 is slidably connected to the clamping arm 373. The flexible clamping block 377 protrudes from the outer side of the clamping arm 373. The top ends of the slider 375 are rounded. The two sides of the second button 3712 are... The sides are chamfered. The slider 375 is located between the two second buttons 3712. When the slider 375 moves, it squeezes the second buttons 3712. The second buttons 3712 and the second alarm 3711 are electrically connected, and pressing the second button 3712 controls the second alarm 3711 to sound an alarm. The first elastic rod 378 and the slider 375 are slidably connected. The fourth spring 3710 is located between the fixing ring 379 and the inner wall of the slider 375. One end of the two pull chains 31 of the clamping mechanism 37 is fixed to the frame of the power tower body 1. By rotating the second threaded rod 374, the clamping arms 373 are driven to move closer to each other, so that the flexible clamping block 377 contacts the frame of the power tower body 1. At this time, the first elastic rod 378 slides in the inner cavity of the slider 375. This causes the fixed ring 379 to compress the fourth spring 3710. At this time, the flexible clamping block 377 and the frame of the power tower body 1 are flexibly fixed. The clamping arm 373 continues to move until it is in close contact with the frame of the power tower body 1. At this time, the clamping mechanism 37 as a whole and the power tower body 1 maintain a fixed connection to achieve a double clamping effect, eliminating slippage at the connection point and ensuring that the force direction of the cable chain 31 is always constant, forming a continuous and reliable flexible constraint system that can stably share the wind load for a long time. When the power tower body 1 and the clamping arm 373 slip, the flexible clamping block 377 and the power tower body 1 remain relatively fixed under the elastic force of the fourth spring 3710, so that the slider 375 and the second slide bar 376 slide in the inner cavity of the clamping arm 373.The sliding of slider 375 compresses the second button 3712, causing the fourth spring 3710 to sound an alarm for quick action. Example 2

A ventilation duct has two symmetrically distributed baffles 42, which are in close contact with chamfered ends. A second elastic rod 43 is slidably connected to a wind deflector 41. A fifth spring 44 is located between the inner walls of the baffles 42 and the wind deflector 41. One end of a groove 45 is flush with the outer surface of the baffle 42, and the connecting groove between the groove 45 and the baffle 42 is an inclined surface. The wind deflector 41 and the baffle 42 are used to protect the bottom end of the cable chain 31 and the bottom end of the power tower body 1 from strong winds. Damage to the bottom fasteners and the connectors at the bottom of the cable chain 31 is caused. When strong winds occur, the shield 42 slides in the ventilation slot of the windbreak 41. At this time, the second elastic rod 43 slides in the inner cavity of the windbreak 41 and squeezes the fifth spring 44, which facilitates some wind force to flow through the gap between the two shields 42, thereby preventing strong winds from damaging the windproof component 4. At the same time, the alarm mechanism 46 and the groove 45 squeeze each other, which can sound an alarm to remind the staff to take measures. When the strong wind stops, the elasticity of the fifth spring 44 makes the shield 42 close again, thus protecting the bottom of the power tower body 1 and the cable chain 31, preventing the strong wind from carrying debris to impact the power tower body 1 and the cable chain 31, reducing additional risks. At the same time, when strong winds occur, the windproof component 4 can automatically ventilate a small area according to the wind pressure, effectively reducing the wind pressure on the windbreak 41, avoiding wind pressure accumulation that causes damage to the plate surface, preventing detached parts from damaging the power tower body 1, and increasing the service life of the windproof component 4.
[0026] Please see Figure 12 and Figure 13As shown, the alarm mechanism 46 includes a fixed block 461, an alarm block 462 fixedly mounted on the outer surface of the fixed block 461, a locking rod 463 slidably connected to the inner cavity of the alarm block 462, a locking ball 464 movably connected to one end of the locking rod 463, a third alarm 465 fixedly mounted on the outer surface of the alarm block 462, a connecting ring 466 fixedly mounted on the outer surface of the locking rod 463, a sixth spring 467 sleeved on the outer surface of the locking rod 463, a third button 468 provided on the inner wall of the alarm block 462, the fixed block 461 and the outer surface of the wind deflector 41 fixedly connected, the third alarm 465 and the third button 468 electrically connected, and pressing the third button 468 controls the third alarm 465 to sound an alarm. The loudness and timbre of the alarm sounds of the first alarm 3611, the second alarm 3711, and the third alarm 465 are set differently to facilitate problem differentiation and rapid maintenance. The sixth spring... 467 is located between the inner wall of the connecting ring 466 and the alarm block 462. The connecting ring 466 and the alarm block 462 are slidably connected. The locking ball 464 and the inner cavity of the groove 45 are in close contact. When the baffle 42 moves, the inclined surface at the connection between the baffle 42 and the groove 45 squeezes the locking ball 464. When there is a strong wind, the baffle 42 slides in the inner cavity of the wind deflector 41, causing the locking ball 464 to slide in the inner cavity of the groove 45. At this time, the locking ball 464 moves to the inclined surface of the groove 45, causing the outer surface of the baffle 42 to squeeze the locking ball 464. At the same time, the locking rod 463 slides in the inner cavity of the alarm block 462. The sliding of the locking rod 463 drives the connecting ring 466 to slide in the inner cavity of the alarm block 462 and squeezes the sixth spring 467. At the same time, the sliding of the locking rod 463 squeezes the third button 468, causing the third alarm 465 to sound an alarm, which facilitates maintenance by staff and the arrangement of subsequent wind-resistant work.
[0027] In summary, the cable assembly 3 and the windproof assembly 4 are used to protect the main body of the power tower 1. The cable assembly 3 has elastic deformation and energy dissipation capabilities, which can absorb wind-induced vibration energy and prevent the rigid transmission of wind load to the tower body 1, thus alleviating stress concentration and member buckling problems. The windproof assembly 4 can protect the bottom of the main body of the power tower 1 and the cable assembly 3. The cable chain 31 can provide stable flexible constraints on the main body of the power tower 1, continuously share the lateral wind load, and limit the horizontal sway and severe vibration of the tower body. The first damping mechanism 32 is used to dampen the cable chain in the horizontal direction. The first damping mechanism 31 provides vibration damping, while the second damping mechanism 35 dampes the cable chain 31 vertically, thereby stabilizing the force angle of the cable chain 31, ensuring that the cable chain 31 maintains a constant tension, continuously sharing the lateral wind pressure of the tower, reducing wear and loosening of the bottom connectors, preventing constraint failure, extending the service life of the cables and connecting components, further suppressing the tower's sway amplitude, and improving the stability of the entire wind-resistant cable system from the root, ensuring the long-term safe resistance of the transmission tower against strong winds. The rotation of the first threaded rod 34 can adjust the first damping mechanism 32 on the connecting plate. Positioned at 33, the cable chain 31 remains taut. The clamping mechanism 37 is fixed to the frame of the power tower body 1, ensuring a stable connection between the cable chain 31 and the power tower body 1. When strong winds occur, the shield 42 slides within the ventilation slot of the wind deflector 41. At this time, the second elastic rod 43 slides within the wind deflector 41 and compresses the fifth spring 44, allowing some wind force to flow through the gap between the two shields 42, thus preventing strong winds from damaging the windproof component 4. Simultaneously, the alarm mechanism 46 and the groove 45 compress against each other, triggering an alarm. The staff is reminded to take measures so that when the strong wind stops, the elasticity of the fifth spring 44 will cause the shield 42 to make tight contact again, thus protecting the bottom of the power tower body 1 and the cable chain 31. This prevents the strong wind from carrying debris that could impact the power tower body 1 and the cable chain 31, reducing additional risks. At the same time, when a strong wind strikes, the windproof component 4 can automatically ventilate a small area according to the wind pressure, effectively reducing the wind pressure on the wind shield 41, avoiding wind pressure buildup that could cause damage to the surface of the shield, preventing detached parts from damaging the power tower body 1, and increasing the service life of the windproof component 4.
