Description

Technical Field

[0001] This invention belongs to the technical field of power transmission line safety equipment, and more specifically, it relates to a device and method for preventing wind deflection of transmission tower conductors. Background Technology

[0002] With the accelerated construction of new power systems and the continuous expansion of power grid interconnection, cross-regional and long-distance power transmission projects have become the core backbone supporting the optimal allocation of energy. As the mainstream method of long-distance, high-capacity power transmission, overhead transmission lines, due to their spatial distribution characteristics of "numerous points, long lines, and wide coverage," are exposed to complex natural environments for a long time, and their safe operation is highly correlated with meteorological conditions. In recent years, extreme weather events have occurred frequently around the world, and the proportion of transmission line faults caused by severe convective weather has been rising year by year. Among them, wind deflection accidents have become one of the primary meteorological disasters threatening line safety. Currently, traditional wind deflection prevention measures include adding counterweights, optimizing insulator string length, and installing phase spacers. However, these traditional measures have limitations in adaptability: under extreme conditions such as sudden strong winds and turbulence, their effectiveness in suppressing conductor sway is limited, making it difficult to meet the safety protection requirements under complex weather conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a device and method for preventing wind deflection of transmission tower conductors, which aims to solve the problem that traditional wind deflection prevention measures have limited effectiveness in suppressing conductor swaying and are difficult to meet the safety protection requirements under complex meteorological conditions.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: Firstly, a device for preventing wind deflection of transmission tower conductors is provided, comprising: A support assembly is fixedly connected to the crossarm of the tower; a wind-response damper is hinged to the end of the support assembly; the wind-response damper is used to absorb the vibration of the conductor. An insulating rod is connected at its top to the wind-response damper and at its bottom to a connecting assembly; the top of the connecting assembly is fixedly connected to the crossarm of the iron tower. The information acquisition module is used to collect and output wind speed information; The controller is communicatively connected to the information acquisition module and the wind response damper; the controller is configured to: receive the wind speed information; and adjust the opening of the damping hydraulic valve in the wind response damper according to the wind speed information, so as to absorb the vibration of the conductor under different weather conditions.

[0005] In one possible implementation, a T-shaped connecting plate is fixedly connected to the end of the support assembly, and one end of the wind-response damper is hinged to the T-shaped connecting plate.

[0006] In one possible implementation, the support component includes: The upper angle steel includes two horizontal angle steels; the two horizontal angle steels are provided with an included angle, and one end is fixedly connected to form a connecting part; the other end of the horizontal angle steels is fixedly connected to the crossarm of the iron tower; the T-shaped connecting plate is fixedly connected to the connecting part; and The oblique angle steel includes two oblique angle steels; the two oblique angle steels are respectively located below the two horizontal angle steels, one end of the oblique angle steel is fixedly connected to the connecting part, and the other end is fixedly connected to the crossarm of the iron tower; there is an included angle between the oblique angle steel and the horizontal angle steel at its top, as well as between the two oblique angle steels.

[0007] In one possible implementation, the T-shaped connecting plate includes: The flange of the T-shaped upper plate is fixedly connected to the connecting part; the flange of the T-shaped upper plate is horizontally arranged; and The web of the T-shaped plate is fixedly connected to the lower surface of the upper flange of the T-shaped plate; the web of the T-shaped plate is perpendicular to the upper flange of the T-shaped plate; the wind response damper is hinged to the web of the T-shaped plate.

[0008] In one possible implementation, the wind-response damper is collinear with the insulating rod, and a triangle is formed between the connecting assembly, the insulating rod, and the support assembly.

[0009] In one possible implementation, the connection component includes: The top connecting plate is fixedly connected to the crossarm of the iron tower. A suspension string, the top of which is hinged to the top connecting plate; an angle is provided between the suspension string and the insulating rod; and The bottom connecting plate is hinged to the top connecting plate.

[0010] The beneficial effects of the transmission tower conductor anti-wind deflection device provided by this invention are as follows: Compared with the prior art, the transmission tower conductor anti-wind deflection device of this invention, through the fixed connection between the support component and the tower crossarm, can provide a stable installation foundation for subsequent components, ensuring the stability of the overall structure in complex environments and avoiding the impact of loose connections on the anti-wind deflection effect. The wind response damper hinged at the end of the support component can directly act on the conductor, effectively absorbing conductor vibration and reducing the sway amplitude of the conductor caused by wind, thereby improving the protection capability of the conductor from the core component level.

[0011] The insulating rod connects the wind response damper to the connecting assembly, which is then fixed to the tower crossarm. This connection method further optimizes the stress distribution of the device, enabling synergistic effects among components, enhancing the suppression of conductor vibration, and preventing damage caused by excessive stress on a single component. The information acquisition module can obtain wind speed information in real time, providing accurate data for subsequent adjustments. This allows the device to respond promptly to changes in external wind force, overcoming the limitations of traditional measures that cannot dynamically adjust according to wind speed.

[0012] The communication connection between the controller and the information acquisition module and the wind response damper allows the controller to precisely adjust the opening of the damping hydraulic valve in the wind response damper based on the acquired wind speed information. Under different weather conditions, the damping force of the wind response damper can be flexibly adjusted by changing the opening of the damping hydraulic valve. This avoids excessive damping and resource waste in light winds, and provides stronger damping effects in extreme conditions such as strong winds or sudden strong winds, effectively suppressing conductor sway and meeting the safety protection requirements under complex weather conditions. This solves the problems of insufficient adaptability and limited suppression effect of traditional measures.

[0013] Secondly, a method for preventing wind deflection of transmission tower conductors is provided, applied to the wind deflection prevention device for transmission tower conductors as described in one aspect, comprising the following steps: Get real-time wind speed information; The opening of the damping hydraulic valve in the wind response damper is adjusted according to the wind speed information in order to absorb the vibration of the conductor under different weather conditions.

[0014] In one possible implementation, adjusting the opening of the damping hydraulic valve in the wind response damper based on the wind speed information includes: The real-time wind speed information is preprocessed to obtain preprocessed wind speed information; Calculate the wind speed change based on the preprocessed wind speed information; The opening degree of the damping hydraulic valve in the wind response damper is adjusted according to the wind speed change range or the pre-processed wind speed information.

[0015] In one possible implementation, adjusting the opening of the damping hydraulic valve in the wind response damper based on the wind speed change amplitude or the preprocessed wind speed information includes: If the pre-processed wind speed information is lower than the first wind speed threshold, the opening of the damping hydraulic valve is adjusted to the first opening; if the pre-processed wind speed information is not lower than the first wind speed threshold and is lower than the second wind speed threshold, the opening of the damping hydraulic valve is adjusted to the second opening; if the pre-processed wind speed information is not lower than the second wind speed threshold, or if the wind speed change amplitude is not lower than the change threshold, the opening of the hydraulic damping valve is adjusted to the third opening.

[0016] In one possible implementation, the first wind speed threshold is lower than the second wind speed threshold, which is lower than the third wind speed threshold; the first opening degree is greater than the second opening degree, which is greater than the third opening degree.

[0017] The beneficial effects of the wind deflection prevention method for transmission tower conductors provided by this invention are as follows: Compared with the prior art, this invention's method for wind deflection prevention of transmission tower conductors, by acquiring real-time wind speed information, can promptly capture the dynamic changes in external wind force, providing accurate data support for subsequent wind deflection prevention adjustments and avoiding the problem of delayed protective measures due to the inability to perceive wind speed changes in real time. Adjusting the opening of the damping hydraulic valve in the wind response damper based on real-time wind speed information allows the damper's operating state to match the current wind conditions. This avoids resource waste caused by excessive damping when the wind force is low, and promptly enhances the damping effect to suppress conductor vibration when the wind force increases, breaking the limitations of the fixed protection mode of traditional measures.

[0018] This method can flexibly adapt to various wind scenarios under different weather conditions. Whether it is normal light wind or extreme conditions such as sudden strong winds and turbulence, it can ensure that the suppression effect on conductor sway is always optimal by dynamically adjusting the opening of the damping hydraulic valve. This dynamic adjustment method effectively makes up for the lack of adaptability of traditional measures, greatly improves the safety protection capability of transmission lines in complex weather environments, reduces the risk of line faults caused by wind deflection accidents, and ensures the stability and reliability of long-distance, large-capacity power transmission.

[0029] Reference Figures 1 to 5 The present invention will now describe the anti-wind deflection device and method for transmission tower conductors.

[0030] In one aspect, a wind-resistant device for transmission tower conductors is provided, comprising: a support assembly 2, an insulating rod 5, an information acquisition module, and a controller. Support assembly 2 is fixedly connected to the crossarm 1 of the tower; a wind-response damper 4 is hinged to the end of support assembly 2; the wind-response damper 4 is used to absorb conductor vibration. The top of the insulating rod 5 is connected to the wind-response damper 4, and the bottom is hinged to a connecting assembly; the top of the connecting assembly is fixedly connected to the crossarm 1 of the tower. The information acquisition module is used to collect and output wind speed information. The controller is communicatively connected to the information acquisition module and the wind-response damper 4; the controller is configured to: receive wind speed information; and adjust the opening of the damping hydraulic valve in the wind-response damper 4 according to the wind speed information, so as to absorb conductor vibration under different weather conditions.

[0031] By fixing the support assembly 2 to the tower crossarm 1, a stable mounting platform is provided for the wind-response damper 4, ensuring that the wind-response damper 4 will not shift or loosen due to external forces during operation, and can continuously and stably perform its vibration absorption function. The hinged design between the wind-response damper 4 and the support assembly 2 allows the wind-response damper 4 to adapt to the direction and amplitude of conductor vibration, avoiding stress concentration in components that may be caused by rigid connections, extending the service life of the wind-response damper 4, and making the vibration absorption process more flexible and efficient.

[0032] The insulating rod 5 connects the wind-response damper 4 to the connecting assembly, achieving both insulation isolation between the conductor and the tower crossarm 1, ensuring the electrical safety of the transmission line, and effectively transmitting the conductor's vibration to the wind-response damper 4. This allows the wind-response damper 4 to act precisely on the vibration source, improving vibration absorption. The top of the connecting assembly is fixed to the tower crossarm 1, further optimizing the stress structure of the entire device. This allows the wind load and vibration load on the conductor to be distributed to the tower crossarm 1 through the insulating rod 5 and the connecting assembly, preventing damage to a single component due to excessive load.

[0033] The information acquisition module can collect and output wind speed information in real time, providing the controller with accurate meteorological data support. This allows the controller to promptly grasp the current wind conditions and avoid untimely damping adjustments due to information lag. The controller adjusts the opening of the damping hydraulic valve in the wind response damper 4 based on the wind speed information, achieving dynamic adaptation of the damping force. This ensures that the wind response damper 4 maintains optimal vibration absorption under different weather conditions. For example, the damping force can be appropriately reduced in light winds to avoid energy waste, while the damping force can be increased in strong winds to effectively suppress severe conductor vibrations. This comprehensively improves the device's adaptability to complex weather conditions and effectively ensures the safe and stable operation of the transmission line.

[0034] In one possible implementation, a T-shaped connecting plate 3 is fixedly connected to the end of the support component 2, and one end of the wind response damper 4 is hinged to the T-shaped connecting plate 3.

[0035] By fixing a T-shaped connecting plate to the end of the support component 2, the wind-response damper 4 is hinged to the T-shaped connecting plate, providing a stable and flexible installation foundation for the wind-response damper 4. This connection method ensures the reliability of the connection between the wind-response damper 4 and the support component 2, and allows the wind-response damper 4 to adapt to changes in conductor vibration and wind speed during operation, avoiding stress concentration in components caused by rigid connections and extending the service life of the wind-response damper 4. At the same time, the structural design of the T-shaped connecting plate facilitates precise positioning of the installation position of the wind-response damper 4, ensuring that the wind-response damper 4 can accurately act on conductor vibration absorption, improving the overall wind deflection prevention effect of the device.

[0036] In one possible implementation, the support component 2 includes: an upper angle steel and a diagonal angle steel.

[0037] The upper angle steel includes two horizontal angle steels 10; the two horizontal angle steels 10 have an included angle between them, and one end is fixedly connected to form a connecting part; the other end of the horizontal angle steel 10 is fixedly connected to the tower crossarm 1; the T-shaped connecting plate 3 is fixedly connected to the connecting part. The oblique angle steel includes two oblique angle steels 13; the two oblique angle steels 13 are respectively located below the two horizontal angle steels 10, one end of the oblique angle steel 13 is fixedly connected to the connecting part, and the other end is fixedly connected to the tower crossarm 1; there are included angles between the oblique angle steel 13 and the top horizontal angle steel 10, as well as between the two oblique angle steels 13.

[0038] In a preferred embodiment, adjacent horizontal angle steels 10 and oblique angle steels 13 are located in the same vertical plane, and a connecting plate is provided at the intersection of adjacent horizontal angle steels 10 and oblique angle steels 13. Both horizontal angle steels 10 and oblique angle steels 13 are fixed to the connecting plate by high-strength bolts 11.

[0039] The support assembly 2 consists of upper angle steel and diagonal angle steel. The two horizontal angle steels 10 of the upper angle steel form an included angle and are fixedly connected to form a connection, providing stable upper support for the T-shaped connecting plate and the wind response damper 4. Simultaneously, the two horizontal angle steels 10 are fixed to the tower crossarm 1, expanding the connection range between the support assembly 2 and the tower crossarm 1 and enhancing the stability of the upper structure. The two diagonal angle steels 13 are located below the horizontal angle steels 10 and are fixed to the connection and the tower crossarm 1. This design forms a triangular support structure, effectively dispersing the force transmitted from the wind response damper 4 and conductor vibration to the support assembly 2, reducing the risk of deformation of the support assembly 2. The included angles between the diagonal angle steels 13 and the horizontal angle steels 10, as well as between the two diagonal angle steels 13, further optimize the force transmission path, ensuring that the support assembly 2 maintains good structural strength when subjected to loads in different directions, ensuring stable operation of the device under extreme conditions such as strong winds.

[0040] In one possible implementation, the T-shaped connecting plate 3 includes an upper flange 3-1 and a web 3-2.

[0041] The upper flange 3-1 of the T-shaped plate is fixedly connected to the connecting part; the upper flange 3-1 of the T-shaped plate is horizontally positioned. The web 3-2 of the T-shaped plate is fixedly connected to the lower surface of the upper flange 3-1 of the T-shaped plate, and the web 3-2 of the T-shaped plate is perpendicular to the upper flange 3-1 of the T-shaped plate, and the web is positioned at the centerline of the upper flange 3-1 of the T-shaped plate; the wind-response damper 4 is hinged to the web 3-2 of the T-shaped plate. A mounting hole is provided on the web of the T-shaped plate, and a U-shaped ring 12 is installed in the mounting hole, which can rotate freely around the mounting hole. The wind-response damper 4 is hinged to the web of the T-shaped plate through the U-shaped ring 12.

[0042] The upper flange of the T-shaped connecting plate is horizontally positioned and fixed to the connection part of the support component 2. This ensures a smooth connection surface between the T-shaped connecting plate and the support component 2, improving the connection's strength and preventing excessive local stress caused by unevenness. The web of the T-shaped plate is vertically fixed to the lower surface of the upper flange and hinged to the wind response damper 4. The vertically positioned web provides vertical installation space for the wind response damper 4, making its hinge position more reasonable and facilitating its rotation in the up-down or left-right directions during operation, better adapting to the conductor's vibration direction. This T-shaped structure design simplifies the manufacturing process of the T-shaped connecting plate and provides flexible movement space for the wind response damper 4 while ensuring structural strength, thus improving the efficiency of the wind response damper 4 in absorbing conductor vibration.

[0043] In one possible implementation, the wind-response damper 4 and the insulating rod 5 are collinear, and a triangle is formed between the connecting assembly, the insulating rod 5, and the support assembly 2. The included angle between the wind-response damper 4 and the insulating rod 5 is 30°-45°.

[0044] The wind-response damper 4 and the insulating rod 5 are arranged coaxially, enabling the damping force generated by the wind-response damper 4 to be directly and efficiently transferred to the insulating rod 5, and then act on the conductor through the insulating rod 5. This reduces the loss of damping force during transmission and ensures that the wind-response damper 4 maximizes its absorption effect on conductor vibration. A triangular structure is formed between the connecting components, the insulating rod 5, and the support component 2. Triangles have strong stability characteristics, and this structure effectively enhances the overall deformation resistance of the device, preventing significant swaying or displacement under strong winds. The triangular structure also makes the force distribution among the components more balanced, evenly distributing the load generated by conductor vibration and wind force onto the support component 2 and the connecting components, reducing the stress on individual components, extending the service life of each component, and improving the reliability of the device under complex weather conditions.

[0045] In one possible implementation, the connecting components include a top connecting plate 9, a suspension string 8, and a bottom connecting plate 6.

[0046] The top connecting plate 9 is fixedly connected to the tower crossarm 1. The top of the suspension string 8 is hinged to the top connecting plate 9; there is an angle between the suspension string 8 and the insulating rod 5. The bottom connecting plate 6 is hinged to the bottom of the suspension string 8 and the top connecting plate 9.

[0047] The top connecting plate 9 of the connecting assembly is fixed to the tower crossarm 1, providing a stable upper fixing point for the entire connecting assembly and ensuring a reliable connection between the connecting assembly and the tower crossarm 1. The top of the suspension string 8 is hinged to the top connecting plate 9, and the bottom is hinged to the bottom connecting plate 6. This hinged structure gives the suspension string 8 a certain degree of freedom of movement, allowing it to swing adaptively under conductor vibration or wind force, avoiding excessive torque or tension on the suspension string 8 or insulating rod 5 due to rigid connection. An angle is provided between the suspension string 8 and the insulating rod 5. This angle allows for a reasonable force angle between the suspension string 8 and the insulating rod 5. When the insulating rod 5 is subjected to conductor vibration or wind force, the suspension string 8 can help disperse the force on the insulating rod 5 through its own swing and angle adjustment, reducing the risk of deformation of the insulating rod 5. At the same time, it can work with the wind response damper 4 and the insulating rod 5 to maintain the stability of the conductor, further improving the anti-wind deflection effect of the device.

[0048] The beneficial effects of the transmission tower conductor anti-wind deflection device provided by this invention are as follows: Compared with the prior art, the transmission tower conductor anti-wind deflection device of this invention, by setting up a support component 2, a wind response damper 4, an insulating rod 5, a connecting component, an information acquisition module, and a controller, constructs a transmission tower conductor anti-wind deflection system that combines structural support and dynamic adjustment functions. It can synergistically improve the anti-wind deflection effect from both structural stability and damping adaptability aspects. The support component 2 is fixed on the tower crossarm 1, providing a stable installation foundation for the wind response damper 4. The wind response damper 4 acts directly on the conductor connected to the insulating rod 5, which can specifically absorb conductor vibration and reduce the sway amplitude of the conductor caused by wind force. The cooperation between the connecting component, the insulating rod 5, and the support component 2 further optimizes the force transmission path of the conductor on the tower crossarm 1, avoiding structural damage caused by overload of a single component.

[0049] The information acquisition module collects wind speed information in real time and transmits it to the controller. The controller adjusts the opening of the damping hydraulic valve in the wind response damper 4 according to the wind speed changes, realizing dynamic adaptation of the damping force. When the wind speed is low, the damping force can be kept within a reasonable range by adjusting the opening, which meets the needs of absorbing minor vibrations and avoids energy waste caused by excessive damping. When the wind speed increases or there is a sudden strong wind, the controller can quickly increase the damping force, enhance the suppression effect on the severe vibration of the conductor, and effectively cope with the risk of wind deflection under extreme conditions. Compared with the traditional fixed damping mode, it greatly improves the device's adaptability to complex meteorological conditions.

[0050] The end of the support assembly 2 is hinged to the wind response damper 4 via a T-shaped connecting plate. This connection method ensures structural robustness while providing the wind response damper 4 with a certain degree of freedom of movement, allowing it to adaptively adjust according to the direction and angle of conductor vibration. This ensures that the damping force always acts efficiently on vibration absorption, avoids stress concentration in components caused by rigid connections, and extends the service life of the wind response damper 4. The horizontal upper flange of the T-shaped connecting plate is fitted and fixed to the connection part of the support assembly 2, while the vertical web is hinged to the wind response damper 4. The structural design is simple and the stress distribution is reasonable, simplifying the installation process and maintaining stable connection performance during long-term use.

[0051] Support component 2 consists of upper angle steel and diagonal angle steel. The two horizontal angle steels 10 of the upper angle steel form an included angle and are fixed to the tower crossarm 1, forming a stable upper support structure. The diagonal angle steel forms a triangular support below the horizontal angle steels 10, further dispersing the load transmitted by the wind response damper 4 and conductor vibration, and enhancing the deformation resistance of support component 2. This multi-angle steel collaborative support design enables support component 2 to maintain structural stability when subjected to wind forces from different directions and conductor tension, avoiding component bending or breakage due to excessive local stress, and providing reliable structural protection for the entire wind deflection prevention device.

[0052] The top connecting plate 9 in the connecting assembly is fixed to the tower crossarm 1. The suspension string 8 is connected to the top connecting plate 9 and the bottom connecting plate 6 by a hinge, and there is an angle between the suspension string 8 and the insulating rod 5. This structure allows the suspension string 8 to swing slightly with conductor vibration and wind speed changes, helping to adjust the stress state of the insulating rod 5 and reduce the torque or tension caused by the rigid constraint of the insulating rod 5. At the same time, the wind response damper 4 is set colinearly with the insulating rod 5 to ensure that the damping force is directly and efficiently transmitted to the insulating rod 5. The triangular structure formed by the connecting assembly, the insulating rod 5 and the support assembly 2 utilizes the stability characteristics of triangles to further improve the overall wind resistance of the device, prevent the conductor from displaced significantly under strong winds, and ensure the safe operation of the transmission line.

[0053] Secondly, a method for preventing wind deflection of transmission tower conductors is provided, applicable to the wind deflection prevention device for transmission tower conductors as described in the first aspect, comprising the following steps: S100. Obtain real-time wind speed information.

[0054] S200. Adjust the opening of the damping hydraulic valve in the wind response damper according to the wind speed information in order to absorb the vibration of the conductor under different weather conditions.

[0055] In one possible implementation, S200. adjusts the opening of the damping hydraulic valve in the wind response damper according to the wind speed information, including: S210. Preprocess the real-time wind speed information to obtain preprocessed wind speed information; use Outliers in the implemented wind speed information are removed as a principle. The following formula is used to identify and remove outlier data:

[0056] in, For the first Real-time wind speed information at each point in time; This is the average of real-time wind speed information; This represents the standard deviation of real-time wind speed information.

[0057] Fill in missing values ​​in the data using the following formula:

[0058] in, No. Fill-in values ​​for missing time points; and These are the effective real-time wind speed information adjacent to the missing point.

[0059] S220. Calculate the wind speed change range based on the preprocessed wind speed information; S230. Adjust the opening of the damping hydraulic valve in the wind response damper according to the wind speed change range or the pre-processed wind speed information.

[0060] In one possible implementation, S230. Adjusting the opening of the damping hydraulic valve in the wind response damper based on the wind speed change magnitude or pre-processed wind speed information, including: If the pre-processed wind speed information is lower than the first wind speed threshold, the opening of the damping hydraulic valve is adjusted to the first opening; if the pre-processed wind speed information is not lower than the first wind speed threshold and is lower than the second wind speed threshold, the opening of the damping hydraulic valve is adjusted to the second opening; if the pre-processed wind speed information is not lower than the second wind speed threshold, or if the wind speed change amplitude is not lower than the change threshold, the opening of the hydraulic damping valve is adjusted to the third opening.

[0061] In one possible implementation, the first wind speed threshold is lower than the second wind speed threshold, which is lower than the third wind speed threshold; the first opening degree is greater than the second opening degree, which is greater than the third opening degree.

[0062] When the pre-processed wind speed information is below the first wind speed threshold, it indicates good weather, low wind force, and low conductor sway. The opening of the damping hydraulic valve needs to be increased to make the wind-sound damper softer and able to absorb small-amplitude vibrations. When the pre-processed wind speed information is not lower than the first wind speed threshold but lower than the second wind speed threshold, it indicates relatively stable weather and high wind force. The opening of the damping hydraulic valve needs to be decreased to stiffen the wind-sound damper, enabling it to absorb moderate-amplitude vibrations. When the pre-processed wind speed information is not lower than the second wind speed threshold, or the wind speed variation is not lower than the variation threshold, it indicates unstable weather, with strong and fluctuating wind force. In this case, the opening of the damping hydraulic valve needs to be further decreased to stiffen the wind-sound damper further, enabling it to absorb larger and more drastically changing vibrations, thus maintaining conductor stability.

[0063] The beneficial effects of the wind deflection prevention method for transmission tower conductors provided by this invention are as follows: Compared with the prior art, this invention provides a scientific and dynamic operating control logic for the wind deflection prevention device for transmission tower conductors, enabling the device to accurately adjust the damping effect according to actual meteorological conditions, significantly improving the absorption capacity of conductor vibration. Firstly, real-time wind speed information is acquired, allowing for timely capture of current wind force changes and providing real-time data support for subsequent damping adjustments. This avoids the device's inability to respond promptly to severe conductor vibrations caused by sudden wind speed changes due to information lag, ensuring that the adjustment action is synchronized with actual wind conditions.

[0064] By adjusting the opening of the damping hydraulic valve in the wind response damper based on the acquired wind speed information, the limitations of the traditional fixed damping mode are broken, allowing the damping force to flexibly adapt to changes in wind speed. When the wind speed is low, the damping force can be controlled within a suitable range by adjusting the opening, which can effectively absorb slight vibrations of the conductor without wasting energy due to excessive damping force. When the wind speed increases, the damping force can be increased in time to strongly suppress large swings of the conductor caused by strong winds, ensuring the stability of the conductor operation and allowing the device to maintain the best anti-wind deflection effect under different weather conditions.

[0065] Preprocessing real-time wind speed information and calculating the magnitude of wind speed changes can filter out interference signals in the wind speed data, such as abnormal values ​​with instantaneous fluctuations, ensuring that the acquired wind speed information is more accurate and reliable, providing an accurate basis for subsequent opening adjustments. Simultaneously, by combining the adjustment strategy with the magnitude of wind speed changes, it not only focuses on the current wind speed magnitude but also on the rate of increase or decrease in wind speed. This allows for early prediction of potential vibration risks to the conductor. For example, when the wind speed change is significant, even if the current wind speed has not reached its extremely high value, the opening of the damping hydraulic valve can be adjusted in advance, enhancing the device's ability to respond to sudden changes in wind force and preventing severe vibration of the conductor due to sudden changes in wind speed.

[0066] By setting different wind speed thresholds and variation thresholds, along with corresponding opening levels, the damping adjustment process becomes more standardized and operable. The division of different thresholds clarifies the adjustment standards for different wind scenarios, avoiding the subjectivity and uncertainty of human judgment and ensuring that each adjustment accurately matches the current operating conditions. Furthermore, the correspondence between opening and thresholds aligns with the logic of wind force and damping requirements: lower wind speeds correspond to larger openings, achieving smaller damping forces to accommodate minor vibrations; higher wind speeds or more drastic changes correspond to smaller openings, providing greater damping forces to suppress strong vibrations. This tiered adjustment method further optimizes the device's wind deflection resistance, ensuring the conductor operates safely and stably under various wind conditions.
