Description

Technical Field

[0001] This invention relates to the field of transmission tower technology, specifically to a wind-resistant traction device for transmission towers. Background Technology

[0002] With the rapid development of the power industry, the coverage of power transmission networks is constantly expanding. As the core supporting facility for power transmission, transmission towers face increasingly complex operating environments. Frequent extreme weather events such as strong winds, torrential rains, and blizzards place higher demands on the structural stability of transmission towers. Strong wind loads are one of the main causes of transmission tower damage. Statistics show that thousands of transmission towers collapse and line faults are caused by strong winds globally each year, resulting in direct economic losses of hundreds of millions of yuan.

[0003] Existing wind-resistant designs for transmission towers are primarily based on traditional structural mechanics principles. These designs enhance wind resistance by increasing the cross-sectional dimensions of tower components, using high-strength steel, and optimizing tower joint connections. For example, thicker steel plates or high-strength alloy materials are used in the design of tower columns and diagonal braces to strengthen the components' resistance to bending and shearing. Bolt groups are used at tower joints to improve their tensile and torsional resistance. However, these wind-resistant measures based on strengthening the structure have several limitations: Firstly, excessively increasing component dimensions and using high-strength materials significantly increases manufacturing costs and construction difficulty, while also increasing the tower's weight and placing higher demands on the foundation's bearing capacity. Secondly, these rigid protective measures cannot effectively buffer the instantaneous impact load of strong winds on the tower; when the wind force exceeds the tower's bearing capacity limit, sudden damage may still occur.

[0004] Therefore, developing a wind-resistant traction device for transmission towers that can adapt to changes in wind direction, possesses efficient buffering performance, and effectively suppress tower sway has become an urgent technical problem to be solved in the field of power transmission equipment protection. This invention addresses the shortcomings of the existing technology by proposing a structurally sound wind-resistant traction device for transmission towers with excellent protective effects, thus filling a gap in the current technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing wind-resistant devices for transmission towers, such as their inability to adapt to changes in wind direction, poor buffering effect, and insufficient suppression of tower swaying, and to provide a wind-resistant traction device for transmission towers. This device achieves adaptive adjustment to different wind directions by incorporating rotatable wind-resistant components. By optimizing the buffering mechanism and counterweight structure, it enhances the buffering and unloading capacity against wind impact loads. By adding anti-sway components, it effectively suppresses the swaying of the transmission tower top, thereby comprehensively improving the structural stability and operational safety of the transmission tower in strong wind environments and reducing the probability of power outages.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A wind-resistant traction device for transmission towers, including transmission tower components.

[0007] The transmission tower assembly includes a concrete base, a steel frame installed on top of the concrete base, cable mounting brackets on both sides of the steel frame, windproof components connected around the steel frame, and anti-sway components installed in the inner cavity at the top of the steel frame.

[0008] The windproof component includes a fixed base, a rotating platform mounted on the top of the fixed base, a buffer frame mounted on the rotating platform, a movable frame mounted inside the buffer frame, a spring rod and a steel wire rope mounted inside the movable frame, and a connecting platform mounted on the other end of the steel wire rope, the connecting platform being fixedly connected to the steel frame.

[0009] A counterweight is installed in the middle of the wire rope, and the counterweight is made of concrete.

[0010] The buffer frame has guide grooves on its inner walls on both sides, and the two ends of the movable frame are located in the guide grooves. The spring rod is located on both sides of the movable frame, and its other end is fixedly connected to the buffer frame.

[0011] The anti-sway component includes a mounting frame, a locking platform is mounted on the top of the mounting frame, a connecting rope is fixedly connected to the locking platform, a pulley is mounted on the bottom of the mounting frame, the connecting rope passes through the mounting frame and is wound around the pulley, and an anti-sway damping ball is mounted on the bottom of the connecting rope.

[0012] Connecting frames are provided at the four corners of the mounting frame, and the connecting frames are fixedly connected to the steel frame.

[0013] The rotating platform is rotatably connected to the buffer frame. The rotating platform has shafts on both sides, and the buffer frame has connecting holes on both sides corresponding to the shafts.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. High-efficiency buffering and unloading performance: The windproof component incorporates a combination structure of spring rods and a movable frame. The movable frame slides with the buffer frame via guide grooves, ensuring smooth movement during buffering. When strong winds cause displacement of the steel frame, the steel frame pulls the steel wire rope through the connecting platform. The steel wire rope drives the movable frame to compress the spring rod, causing elastic deformation and absorbing a large amount of wind impact energy, effectively buffering the wind load. Simultaneously, the concrete counterweight block in the middle of the steel wire rope generates a reverse tensile force using its own weight, further enhancing the buffering and unloading effect, reducing the displacement of the tower body, and lowering the stress on the tower components.

[0015] 2. Precise Guidance and Stable Transmission: The guide grooves on the inner walls of both sides of the buffer frame and the matching design at both ends of the movable frame provide precise guidance for the reciprocating motion of the movable frame, avoiding jamming or offset during the buffering process and ensuring the stable and reliable operation of the buffering mechanism. The matching of the shafts on both sides of the rotating table with the connecting holes on the buffer frame not only enables the flexible rotation of the buffer frame but also ensures the structural stability during rotation, preventing the failure of the windproof components due to loose rotational connections.

[0016] 3. Comprehensive Anti-sway Protection: This invention incorporates an anti-sway component within the inner cavity of the steel frame top. This component is securely connected to the steel frame via connecting brackets at the four corners of the mounting bracket, ensuring installation stability. The connecting rope within the anti-sway component is wound around a pulley, and its bottom is connected to an anti-sway damping ball. When the top of the steel frame sways due to strong winds, the damping ball generates a reverse damping force under inertia, which is transmitted to the mounting bracket through the connecting rope and pulley, thus suppressing the swaying of the steel frame top. This design effectively reduces the sway amplitude of the transmission tower top, protecting the transmission line connection points at the top and preventing damage to the lines due to excessive swaying.

Detailed Implementation

[0023] See Figure 1-5A wind-resistant traction device for transmission towers offers highly efficient buffering and load-bearing performance during use. The wind-resistant component 200 incorporates a combination structure of a spring rod 250 and a movable frame 240. The movable frame 240 slides with the buffer frame 230 via a guide groove 231, ensuring smooth movement during buffering. When strong winds cause displacement of the steel frame 120, the steel frame 120 pulls the wire rope 260 via a connecting platform 270. The wire rope 260 then compresses the spring rod 250, causing it to elastically deform and absorb a significant amount of wind impact energy, effectively buffering the wind load. Simultaneously, the concrete counterweight 280 in the middle of the wire rope 260 generates a reverse pulling force using its own weight, further enhancing the buffering and load-bearing effect, reducing tower displacement, and lowering the stress on tower components.

[0024] Precise guidance and stable transmission: The guide grooves 231 on both sides of the inner wall of the buffer frame 230 and the matching design of the two ends of the movable frame 240 provide precise guidance for the reciprocating motion of the movable frame 240, avoiding jamming or offset during the buffering process and ensuring the stable and reliable operation of the buffering mechanism. The matching of the shafts on both sides of the rotating table 220 with the connecting holes on the buffer frame 230 not only enables the flexible rotation of the buffer frame 230, but also ensures the structural stability during the rotation process, preventing the failure of the windproof component 200 due to loose rotational connections.

[0025] All-round anti-sway protection: This invention adds an anti-sway component 300 to the inner cavity of the top of the steel frame 120. It is securely connected to the steel frame 120 via connecting brackets 360 at the four corners of the mounting bracket 310, ensuring the installation stability of the anti-sway component 300. The connecting rope 330 in the anti-sway component 300 is wound around a pulley 340, and the bottom is connected to an anti-sway damping ball 350. When the top of the steel frame 120 sways due to strong winds, the anti-sway damping ball 350 generates a reverse damping force under inertia, which is transmitted to the mounting bracket 310 through the connecting rope 330 and pulley 340, thereby suppressing the swaying of the top of the steel frame 120. This design effectively reduces the sway amplitude of the top of the transmission tower, protects the transmission line connection points at the top, and prevents line damage due to excessive swaying.

[0026] See Figure 1-5 A wind-resistant traction device for transmission towers is mainly composed of three parts: transmission tower component 100, wind-resistant component 200, and anti-sway component 300. The structures of each part cooperate with each other to achieve the functions of wind-resistant traction and anti-sway protection for the transmission tower.

[0027] Specific structure and installation of transmission tower assembly 100: The transmission tower assembly 100 is the basic load-bearing structure of this device, used to support the transmission line and install the windproof assembly 200 and the anti-sway assembly 300. Its structural stability directly affects the wind protection effect of the entire device.

[0028] The transmission tower assembly 100 includes a concrete base 110, which serves as the foundation of the entire transmission tower, transferring the entire load of the tower to the ground and ensuring the overall stability of the tower. In this embodiment, the concrete base 110 is constructed of C30 high-strength concrete. An internal steel reinforcement cage is provided within the concrete base 110, welded from HRB400 grade threaded steel bars with a diameter of 25mm and a spacing of 150mm, to enhance the compressive strength and crack resistance of the concrete base 110. The dimensions of the concrete base 110 are determined based on the height and load-bearing requirements of the transmission tower. In this embodiment, the bottom dimensions of the concrete base 110 are 4m × 4m, and the height is 2m. Pre-embedded bolt holes for connection to the steel frame 120 are provided at the top of the base. M30 high-strength bolts are used, with a bolt spacing of 300mm, and a total of 16 pre-embedded bolts are provided to ensure a secure connection between the steel frame 120 and the concrete base 110.

[0029] A steel frame 120 is installed on top of the concrete base 110. The steel frame 120 is the main supporting structure of the transmission tower, used to support the transmission lines and install various protective components. The steel frame 120 is made of Q355B high-strength steel, with a yield strength ≥355MPa and a tensile strength ≥510MPa, ensuring that the steel frame 120 has sufficient load-bearing capacity. The steel frame 120 has a truss structure, assembled from columns, diagonal braces, and crossbars by bolting or welding. In this embodiment, the columns of the steel frame 120 have a cross-sectional dimension of 300mm×300mm square steel pipe with a wall thickness of 12mm. The diagonal braces and crossbars are made of 200mm×200mm square steel pipe with a wall thickness of 10mm. The height of the steel frame 120 is determined according to the required height of the transmission line. In this embodiment, the height of the steel frame 120 is 30m, divided into 10 sections, each section is 3m high. The sections are connected by flanges and high-strength bolts. The flanges are made of steel plates with a thickness of 20mm, and the bolts are M24 high-strength bolts to ensure the stability of the connection between sections.

[0030] Cable mounting racks 130 are installed on both sides of the steel frame 120. These racks are used for installing and securing high-voltage transmission lines. The cable mounting racks 130 are welded from steel plates and include horizontal supports and vertical supports. The horizontal supports are 1.5m long and 10mm thick, while the vertical supports are 0.8m high and 8mm thick. The cable mounting racks 130 are bolted to the columns of the steel frame 120 using M20 high-strength bolts. Each cable mounting rack 130 has four fixing bolts to ensure a secure installation. Cable fixing clamps are installed on the cable mounting racks 130. These clamps are made of aluminum alloy with an anodized surface for excellent corrosion resistance. Rubber pads are placed on the inner side of the clamps to protect the insulation layer of the transmission line and prevent damage to the cables due to friction with the clamps.

[0031] The steel frame 120 is connected to the windproof component 200 on all four sides, and the anti-sway component 300 is installed in the inner cavity of the top of the steel frame 120. To ensure the installation stability of the windproof component 200 and the anti-sway component 300, a reinforcing plate is provided on the steel frame 120 at the corresponding connection points. The reinforcing plate is made of 16mm thick Q355B steel plate and is fixedly connected to the components of the steel frame 120 by welding. The size of the reinforcing plate is determined according to the connection requirements, generally 300mm×300mm. Double-sided welding is used during welding, and the weld height is 10mm to ensure the welding strength.

[0032] The windproof component 200 is the core windproof structure of this device, used to apply traction force to the steel frame 120 and buffer the impact load of strong winds on the steel frame 120. Its structural design directly determines the windproof performance of the device. The windproof components 200 are symmetrically distributed around the steel frame 120. In this embodiment, four sets of windproof components 200 are evenly arranged around each steel frame 120, and the included angle between two adjacent sets of windproof components 200 is 90° to ensure that the traction force on the steel frame 120 is evenly distributed.

[0033] Specific structure and installation of windproof component 200 The windproof component 200 is the core windproof structure of this device, used to apply traction force to the steel frame 120 and buffer the impact load of strong winds on the steel frame 120. Its structural design directly determines the windproof performance of the device. The windproof components 200 are symmetrically distributed around the steel frame 120. In this embodiment, four sets of windproof components 200 are evenly arranged around each steel frame 120, and the included angle between two adjacent sets of windproof components 200 is 90° to ensure that the traction force on the steel frame 120 is evenly distributed.

[0034] The windproof component 200 includes a fixed base 210, which is used to fix the windproof component 200 to the ground and provide stable support for the windproof component 200. The fixed base 210 is made of C30 concrete and has a steel reinforcement frame inside. The structure of the steel reinforcement frame is similar to that of the concrete base 110. The bottom dimensions of the fixed base 210 are 2m × 2m, and the height is 1.5m. The top has pre-embedded bolts for connection with the rotating platform 220.

[0035] A rotating platform 220 is mounted on top of the fixed base 210. The rotating platform 220 is made of cast iron, a material known for its excellent wear resistance and compressive strength, ensuring long-term stable operation. A mounting plate is installed at the bottom of the rotating platform 220, which is fixedly connected to the fixed base 210 using pre-embedded bolts. The mounting plate is 20mm thick, and eight M24 high-strength bolts are used to ensure a secure connection between the rotating platform 220 and the fixed base 210. A boss with a diameter of 500mm and a height of 100mm is located on the top of the rotating platform 220. Shafts made of 45# steel, with a diameter of 50mm and a length of 200mm, are fixedly connected to the rotating platform 220 by welding, with a weld height of 15mm.

[0036] A buffer frame 230 is installed on the rotating table 220. The buffer frame 230 is welded from steel plates and has an overall rectangular frame structure. The buffer frame 230 is 2m long, 0.8m wide, and 1m high, and the steel plate is 12mm thick. Connection holes corresponding to the shafts are opened on both sides of the buffer frame 230. The diameter of the connection hole is 52mm, which is 2mm larger than the diameter of the shaft, ensuring that the shaft can rotate freely within the connection hole. The buffer frame 230 is fitted onto the shaft of the rotating table 220 through the connection hole, achieving a rotational connection with the rotating table 220. To ensure smooth rotation, a copper sleeve is installed inside the connection hole. The copper sleeve is made of tin bronze, which has good lubrication performance and wear resistance. The copper sleeve is 5mm thick, with an inner diameter of 50mm and an outer diameter of 52mm, and is interference-fitted with the connection hole.

[0037] A movable frame 240 is installed inside the buffer frame 230. The movable frame 240 is also welded from steel plates, has a rectangular structure, and is 1.8m long, 0.7m wide, and 0.9m high. The steel plate thickness is 10mm. Guide grooves 231 are formed on the inner walls of both sides of the buffer frame 230. The guide grooves 231 have a U-shaped cross-section, a width of 12mm, and a depth of 50mm. The length of the guide grooves 231 is the same as the length of the buffer frame 230. Guide blocks are provided at both ends of the movable frame 240. The dimensions of the guide blocks match the guide grooves 231, and the guide blocks are embedded in the guide grooves 231 to achieve a sliding fit between the movable frame 240 and the buffer frame 230. This guiding structure ensures that the movable frame 240 moves smoothly back and forth within the buffer frame 230 along the direction of the guide grooves 231, avoiding jamming or deviation.

[0038] Spring rods 250 and steel wire ropes 260 are installed inside the movable frame 240. The spring rods 250 are located on both sides of the movable frame 240 and are symmetrically distributed. In this embodiment, two spring rods 250 are set on each side of each movable frame 240, for a total of four spring rods 250. The spring rods 250 are cylindrical helical springs made of 60Si2Mn spring steel, which has good elastic properties and fatigue strength. The diameter of the spring rod 250 is 30mm, the length is 800mm, the spring pitch is 50mm, and the elastic coefficient is 50N / mm. One end of the spring rod 250 is fixedly connected to the movable frame 240 by bolts, and the other end is fixedly connected to the buffer frame 230. M20 high-strength bolts are used to ensure that the spring rod 250 is firmly installed. When the movable frame 240 moves inward toward the buffer frame 230 under the pull of the steel wire rope 260, the spring rods 250 are compressed, generating elastic restoring force, thereby buffering the tension of the steel wire rope 260.

[0039] One end of the wire rope 260 is fixedly connected to the movable frame 240, and the other end is equipped with a connecting platform 270, which is fixedly connected to the steel frame 120. The wire rope 260 is a high-strength galvanized steel wire rope, model 6×19S+FC-15.5, with a nominal tensile strength of 1770MPa, possessing good tensile strength and corrosion resistance. The connection method between the wire rope 260 and the movable frame 240 is as follows: a wire rope fixing seat is provided on the inner side of the movable frame 240. The fixing seat is welded from steel plates and has wire rope clips. The wire rope 260 is fixed to the fixing seat by the wire rope clips. The wire rope clips are made of high-strength aluminum alloy material, and a total of 3 clips are provided to ensure a firm connection. The other end of the wire rope 260 passes through the through hole of the connecting platform 270 and is fixed to the connecting platform 270 by a wire rope clip. The connecting platform 270 is made of steel plate with a thickness of 20mm. The connecting platform 270 is fixedly connected to the reinforcing plate of the steel frame 120 by high-strength bolts. The bolts are M24 high-strength bolts, and a total of 8 bolts are set.

[0040] A counterweight 280 is installed in the middle of the wire rope 260. The counterweight 280 is made of concrete, which has the advantages of low cost and high weight, effectively enhancing the traction stability and buffering effect of the wire rope 260. The counterweight 280 is cylindrical, with a diameter of 300mm, a height of 500mm, and a weight of 200kg. A through hole with a diameter of 16mm is opened in the center of the counterweight 280, through which the wire rope 260 passes. The counterweight 280 is fixedly connected to the wire rope 260 by a wire rope clamp, ensuring that the counterweight 280 can move synchronously with the movement of the wire rope 260. When strong winds cause the steel frame 120 to shift, the wire rope 260 pulls the movable frame 240 to compress the spring rod 250. At the same time, the counterweight 280 moves downward under the action of gravity, generating a reverse pulling force, further buffering the wind impact and reducing the displacement of the steel frame 120.

[0041] Specific structure and installation of anti-sway component 300 The anti-sway component 300 is installed in the inner cavity of the top of the steel frame 120 to suppress the swaying of the top of the steel frame 120 caused by strong winds, protect the transmission line connection parts at the top, and improve the overall stability of the transmission tower.

[0042] The anti-sway component 300 includes a mounting frame 310, which is welded from steel plates and has a square frame structure. The dimensions of the mounting frame 310 match the dimensions of the inner cavity at the top of the steel frame 120. In this embodiment, the side length of the mounting frame 310 is 1.5m and the thickness of the steel plate is 12mm. Connecting frames 360 are provided at the four corners of the mounting frame 310. The connecting frames 360 are made of steel plates, are L-shaped, and have a thickness of 16mm. One end of the connecting frame 360 ​​is fixedly connected to the mounting frame 310 by welding, and the other end is fixedly connected to the reinforcing plate at the top of the steel frame 120 by high-strength bolts. The bolts are M20 high-strength bolts, and each connecting frame 360 ​​is equipped with four bolts to ensure a firm connection between the mounting frame 310 and the steel frame 120.

[0043] A locking platform 320 is mounted on the top of the mounting bracket 310. The locking platform 320 is made of cast iron, cylindrical in shape, with a diameter of 200mm and a height of 100mm. The locking platform 320 is fixedly connected to the mounting bracket 310 with four M16 high-strength bolts. A connecting rope 330 is fixedly connected to the locking platform 320. The connecting rope 330 is made of high-strength nylon rope, possessing good tensile strength and elasticity, with a diameter of 12mm and a breaking strength ≥10kN. The connection method between the connecting rope 330 and the locking platform 320 is as follows: a groove is provided on the top of the locking platform 320, and one end of the connecting rope 330 is embedded in the groove and secured with locking bolts to ensure that the connecting rope 330 will not fall off.

[0044] The mounting bracket 310 has pulleys 340 installed at its bottom. The pulleys 340 are made of cast iron, with a diameter of 100mm and a thickness of 20mm. The pulleys 340 are mounted on a pulley bracket at the bottom of the mounting bracket 310 via pulley axles. These axles are made of 45# steel, with a diameter of 25mm and a length of 150mm. The pulley bracket is made of welded steel plate, with a thickness of 10mm, and is fixedly connected to the mounting bracket 310. The number of pulleys 340 matches the number of connecting ropes 330. In this embodiment, four pulleys 340 are evenly distributed at the bottom of the mounting bracket 310, corresponding to four connecting ropes 330 respectively.

[0045] The connecting rope 330 passes through the mounting bracket 310 and is wound around the pulley 340, with an anti-sway damping ball 350 installed at the bottom of the connecting rope 330. After the connecting rope 330 is led out from the locking platform 320, it passes through a through hole in the mounting bracket 310 and is wound around the pulley 340. The pulley 340 changes the direction of force on the connecting rope 330, causing the connecting rope 330 to extend vertically downward. The anti-sway damping ball 350 is made of high-density rubber material, which has good elasticity and damping performance, and can effectively absorb sway energy. The anti-sway damping ball 350 has a diameter of 500mm and a weight of 50kg. A connecting ring made of stainless steel is provided at the top of the anti-sway damping ball 350, which is fixedly connected to the bottom of the connecting rope 330 by a wire rope clip. When the top of the steel frame 120 sways due to strong winds, the anti-sway damping ball 350 generates a damping force opposite to the direction of swaying under inertia. This force is transmitted to the mounting frame 310 through the connecting rope 330, thereby suppressing the swaying of the top of the steel frame 120 and reducing the swaying amplitude.

[0046] The working principle is as follows: When strong winds act on the steel frame 120 of the transmission tower, the steel frame 120 will be subjected to horizontal wind loads, causing it to tend to displace in the direction of the wind. At this time, the windproof components 200 around the steel frame 120 begin to function: First, since the rotating platform 220 and the buffer frame 230 are rotatably connected, the buffer frame 230 will rotate around the axis of the rotating platform 220 under the action of the wind, causing the traction direction of the wire rope 260 to adaptively adjust with the wind direction, ensuring that the wire rope 260 always applies traction force to the steel frame 120 at the optimal angle. Second, when the steel frame 120 displaces, it will pull the wire rope 260 through the connecting platform 270. The wire rope 260 will drive the movable frame 240 to move inward within the guide groove 231 of the buffer frame 230. The movable frame 240 compresses the spring rods 250 on both sides, causing the spring rods 250 to undergo elastic deformation, absorbing a large amount of wind impact energy and achieving buffering of the wind load. Meanwhile, the concrete counterweight 280 in the middle of the wire rope 260 moves downward under the action of gravity, generating a reverse tension opposite to the displacement direction of the steel frame 120, further enhancing the buffering and unloading effect, reducing the displacement of the steel frame 120, and reducing the stress strength of the steel frame components.

[0047] When strong winds cause the top of the steel frame 120 to sway, the anti-sway component 300 begins to function: the swaying of the top of the steel frame 120 causes the mounting frame 310 to sway synchronously, and the swaying of the mounting frame 310 is transmitted to the connecting rope 330. Due to inertia, the anti-sway damping ball 350 at the bottom of the connecting rope 330 generates a damping force opposite to the direction of swaying. This damping force is transmitted through the connecting rope 330 to the pulley 340, and then through the pulley 340 to the mounting frame 310, thereby suppressing the swaying of the top of the steel frame 120, reducing the amplitude of swaying, and preventing damage to the power transmission line connection parts at the top due to excessive swaying.

[0048] When the wind weakens or disappears, the elastic restoring force of the spring rod 250 pushes the movable frame 240 to move outward, causing the wire rope 260 and counterweight 280 to return to their original positions. The steel frame 120 returns to its initial position under the traction of the wire rope 260. The anti-sway damping ball 350 also returns to its initial state under its own weight and the tension of the connecting rope 330, preparing for the next wind protection.

[0049] When strong winds act on the steel frame 120 of the transmission tower, the steel frame 120 will be subjected to horizontal wind loads, causing it to tend to displace in the direction of the wind. At this time, the windproof components 200 around the steel frame 120 begin to function: First, since the rotating platform 220 and the buffer frame 230 are rotatably connected, the buffer frame 230 will rotate around the axis of the rotating platform 220 under the action of the wind, causing the traction direction of the wire rope 260 to adaptively adjust with the wind direction, ensuring that the wire rope 260 always applies traction force to the steel frame 120 at the optimal angle. Second, when the steel frame 120 displaces, it will pull the wire rope 260 through the connecting platform 270. The wire rope 260 will drive the movable frame 240 to move inward within the guide groove 231 of the buffer frame 230. The movable frame 240 compresses the spring rods 250 on both sides, causing the spring rods 250 to undergo elastic deformation, absorbing a large amount of wind impact energy and achieving buffering of the wind load. Meanwhile, the concrete counterweight 280 in the middle of the wire rope 260 moves downward under the action of gravity, generating a reverse tension opposite to the displacement direction of the steel frame 120, further enhancing the buffering and unloading effect, reducing the displacement of the steel frame 120, and reducing the stress strength of the steel frame components.

[0050] When strong winds cause the top of the steel frame 120 to sway, the anti-sway component 300 begins to function: the swaying of the top of the steel frame 120 causes the mounting frame 310 to sway synchronously, and the swaying of the mounting frame 310 is transmitted to the connecting rope 330. Due to inertia, the anti-sway damping ball 350 at the bottom of the connecting rope 330 generates a damping force opposite to the direction of swaying. This damping force is transmitted through the connecting rope 330 to the pulley 340, and then through the pulley 340 to the mounting frame 310, thereby suppressing the swaying of the top of the steel frame 120, reducing the amplitude of swaying, and preventing damage to the power transmission line connection parts at the top due to excessive swaying.

[0051] When the wind weakens or disappears, the elastic restoring force of the spring rod 250 pushes the movable frame 240 to move outward, causing the wire rope 260 and counterweight 280 to return to their original positions. The steel frame 120 returns to its initial position under the traction of the wire rope 260. The anti-sway damping ball 350 also returns to its initial state under its own weight and the tension of the connecting rope 330, preparing for the next wind protection.
