[0002] With the rapid development of my country's economy, the mileage of transmission lines has continued to increase, and the number of transmission towers has continued to increase. As an important infrastructure for power transmission, the safety and stability of transmission towers are of vital importance. Transmission towers are usually constructed of various angle steels, which are prone to buckling under the influence of various forces such as wind loads, ice loads, and their own weight in the natural environment for a long time. Once the angle steel buckles, it will seriously affect the overall structural stability of the transmission tower, which may cause the interruption of the transmission line, bringing great inconvenience and economic losses to social production and life. Therefore, how to effectively prevent the buckling of the transmission tower angle steel and improve its bearing capacity and stability has become a problem to be solved in the power industry.

[0003] In the prior art, in order to prevent the transmission tower angle steel from buckling, some traditional reinforcement methods are usually used. For example, the strength and stability of the angle steel is enhanced by simply increasing the thickness of the angle steel or adding supports. Some reinforcement measures may simply weld some reinforcing ribs on the outside of the angle steel or use ordinary fixing plates to fix it, thereby improving the angle steel's anti-buckling ability. The traditional method of increasing the thickness of the angle steel or simply adding supports often cannot adapt well to the actual deformation of the angle steel under complex working conditions. Summary of the invention

Two auxiliary installation mechanisms 4 are arranged on the outer side of the limiting plates 302, and the auxiliary installation mechanisms 4 can provide auxiliary positioning function for the reinforcement plate during installation.

[0015] The connecting plate 301 and the limiting plate 302 are connected to the transmission tower angle steel 1 through a fastener 2, and the fastener 2 is composed of a fastening bolt and a locking nut. The connection plate 301 and the limiting plate 302 are connected to the transmission tower angle steel 1 by using a fastener 2, which can ensure the reliability and firmness of the connection. The connecting plate 301 and the limiting plate 302 are connected by a fastener 2, and the connecting plate 301 and the limiting plate 302 are connected to each other by the fastener 2, which not only enhances the structural stability between them, but also makes the entire anti-buckling reinforcement mechanism 3 and the transmission tower angle steel 1 form an organic whole. The outer side of one of the connecting plates 301 is connected to a reinforcing plate 1 303 through a fastener 2, and the outer side of the other connecting plate 301 is connected to a reinforcing plate 2 305 through a fastener 2, and the reinforcing plate 1 303 and the reinforcing plate 2 305 are respectively connected to the outer side of the corresponding position of the connecting plate 301, which can significantly improve the strength of the transmission tower angle steel 1. When the angle steel is subjected to a large pressure or impact force, the reinforcing plate can share part of the load, reducing the stress borne by the connecting plate 301 and the angle steel, thereby further enhancing the anti-buckling ability of the reinforcement mechanism on the transmission tower angle steel 1 and improving the safety of the entire structure. The outer sides of the reinforcing plate 1 303 and the reinforcing plate 2 305 are fixedly connected with a reinforcing plate 306, and the reinforcing plate 306 is fixed on the outer sides of the reinforcing plate, which enhances the overall strength and rigidity of the reinforcing plate 1 303 and the reinforcing plate 2 305. An adjustment component is arranged between the reinforcing plate 1 303 and the reinforcing plate 2 305, and the adjustment component can be adjusted according to different

[0016] See also Figure 1 , Figure 6 and Figure 7 The adjustment assembly includes an extension plate 304, one side of which is fixedly connected to one side of the reinforcing plate 1 303. The extension plate 304 is an important part of the adjustment assembly, so that when adjusting the length, the extension plate 304 can be used as a movable component to cooperate with the extension slot 3011 to adjust the length. The outer side of the reinforcing plate 2 305 is provided with an extension slot 3011, and the extension slot 3011 provides a space for the extension plate 304 to accommodate and slide. When the length or position of the reinforcement mechanism needs to be adjusted, the extension plate 304 can slide in the extension slot 3011, so as to change the distance between the reinforcing plate 1 303 and the reinforcing plate 2 305. The extension plate 304 is connected to the inner wall of the extension slot 3011 by the fastener 2 3010, and the fastener 2 3010 is a screw.

[0017] See also Figure 5The side of the connecting plate 301 that contacts the transmission tower angle steel 1 is provided with an anti-skid groove 1 308. When the connecting plate 301 contacts the transmission tower angle steel 1, the anti-skid groove 1 308 can significantly increase the friction between the two. The side of the limiting plate 302 that contacts the transmission tower angle steel 1 is provided with an anti-skid groove 2 309: The main function of the limiting plate 302 is to limit the angle steel to prevent it from excessive deformation in a specific direction.

[0018] See also Figure 8-Figure 9 , an auxiliary plate 307 is fixedly connected between one reinforcement plate 306 and the reinforcement plate 1 303, and the auxiliary plate 307 is connected between the reinforcement plate 306 and the reinforcement plate 1 303, so that these three components form a more stable overall structure. When the transmission tower angle steel 1 is subjected to external force, the force can be more evenly transmitted and dispersed between the reinforcement plate 306, the reinforcement plate 1 303 and the auxiliary plate 307. An auxiliary plate 307 is fixedly connected between another reinforcement plate 306 and the reinforcement plate 2 305, and the function is the same as above.

[0019] See also Figure 5 and Fig.10 The auxiliary installation mechanism 4 includes a spring 403, which can provide a certain pulling force or pushing force for the guide plate 404, so that the guide plate 404 is more stable and reliable during the movement. An auxiliary groove 401 is provided on the outer side of the limit plate 302, and one end of the spring 403 is fixedly connected to the inner wall of the auxiliary groove 401. The auxiliary groove 401 provides a suitable installation position for the spring 403, so that the spring 403 can be stably fixed on the limit plate 302. The other end of the spring 403 is fixedly connected to the guide plate 404. When the reinforcing plate contacts the guide plate 404, due to the existence of the guide plate 404, the installation path of the reinforcing plate is clearly guided and the actual deformation of the angle steel length can be flexibly adjusted.

[0020] See also Figure 5 and Fig.10 The guide plate 404 is slidably connected to the guide rod 402 at the inner through hole. The guide plate 404 is slidably connected to the guide rod 402 through the inner through hole, providing a guide path for the movement of the guide plate 404.

[0021] See also Figure 2 , Figure 3 and Fig.12, two transmission tower angle steels 1 are connected by a connection reinforcement mechanism 5, which connects the two transmission tower angle steels 1 so that they can work together and bear various loads together. The connection reinforcement mechanism 5 includes two fixed plates 501 and two mounting shells 505. The outer side of the fixed plate 501 is fixedly connected to the outer side of the limit plate 302, and fixed to the outer side of the limit plate 302, providing a stable installation foundation for subsequent connection components. A connecting groove 506 is provided on the outer side of the fixed plate 501, and the connecting groove 506 provides a space for the connecting plate 502 to be installed and slide. The inner wall of the connecting groove 506 is slidably connected with the connecting plate 502, and the connecting plate 502 slides in the connecting groove 506, so that a certain position adjustment can be made according to actual conditions during the installation process. One side of the connecting plate 502 is connected to the fixed plate 501 through a fastener 1-2, and the other side of the connecting plate 502 is connected to the transmission tower angle steel 1 through a fastener 1-2. The connecting plate 502 is connected to the fixed plate 501 and the transmission tower angle steel 1 respectively using a fastener 1-2, which can provide a reliable connection force and ensure the firmness of the connection part. The outer side of the connecting plate 502 is fixedly connected with a connecting block 503, and the connecting block 503 is fixed on the outer side of the connecting plate 502, providing a stable connection point for the connecting rod 504. The opposite sides of the two connecting blocks 503 are both rotatably connected with connecting rods 504, which increases the flexibility and adaptability of the connection reinforcement mechanism 5. It can be folded up before installation, which is convenient for carrying and installation. One end of one of the connecting rods 504 is fixedly connected with an extension plate 1 507, and one end of the other connecting rod 504 is fixedly connected with an extension plate 2 508. The extension plate 1 507 and the extension plate 2 508 are respectively connected to one end of the two connecting rods 504, which increases the overall connectivity and strength of the connection reinforcement mechanism 5. The installation shell 505 is connected to the extension plate 1 507 through the fastener 1 2, and the installation shell 505 is connected to the extension plate 2 508 through the fastener 1 2. The installation shell 505 is connected to the extension plate 1 507 and the extension plate 2 508 using the fastener 1 2, which ensures the firmness and reliability of the connection. During the operation of the transmission tower, the installation shell 505 needs to withstand the force from the connecting rod 504 and other components. Through the connection of the fastener 1 2, these forces can be effectively transmitted to prevent the installation shell 505 from loosening or detaching from the extension plate, thereby ensuring the overall stability of the connection reinforcement mechanism 5.

[0022] See also Figure 2-Figure 3, one end of the two transmission tower angle steels 1 is connected through a connection seat 1 509, and the connection seat 1 509 provides a special connection position for one end of the two transmission tower angle steels 1. In the assembly process of the transmission tower, the end connection of the angle steel is an important link in building the overall structure. One end of the two transmission tower angle steels 1 is connected through a connection seat 2 5010, corresponding to the connection seat 1 509, and the connection seat 2 5010 provides a connection method for the other side of one end of the two transmission tower angle steels 1. It plays a similar role as the connection seat 1 509 in the tower structure, ensuring the connection stability and reliability of the other side of one end of the transmission tower angle steel.

[0023] See also Figure 1-Figure 14 The present invention also provides a method for reinforcing the angle steel of a power transmission tower against buckling, comprising: fixing the above-mentioned device for reinforcing the angle steel of a power transmission tower against buckling on the angle steel of the power transmission tower. The method comprises the following steps: S1. First, prepare all the parts, connecting plate 301, limit plate 302, fastener 1 2, reinforcing plate 1 303, reinforcing plate 2 305, reinforcing plate 306, extension plate 304, fastener 2 3010, etc., and check whether the parts are damaged or deformed; preparing all the parts in advance can avoid the downtime and waiting due to lack of parts during the construction process, and ensure the continuity of the construction progress. This can effectively improve the construction efficiency and reduce unnecessary waste of time. Check whether the parts are damaged or deformed, so that the problematic parts can be found in time and replaced or repaired, ensuring that the parts used during the installation process are intact.

[0024] S2. Place the two connecting plates 301 and the two limiting plates 302 on the outside of the transmission tower angle steel 1 that needs to be reinforced, so that they are roughly in the correct installation position. Note that the anti-skid groove 1 308 on the side of the connecting plate 301 that contacts the transmission tower angle steel 1 and the anti-skid groove 2 309 on the side of the limiting plate 302 that contacts the transmission tower angle steel 1 should be aligned with the surface of the angle steel, which can increase friction and help with subsequent fixation; placing the connecting plate 301 and the limiting plate 302 roughly in the correct position provides a basis for subsequent precise installation. This preliminary positioning allows construction personnel to quickly determine the installation position of each component and improve installation efficiency. Ensuring that the anti-skid groove 1 308 and the anti-skid groove 2 309 are aligned with the surface of the angle steel can increase the friction between the connecting plate 301 and the limiting plate 302 and the angle steel. During the operation of the tower, this friction can effectively prevent relative sliding between the reinforcement components and the angle steel, improve the stability of the connection, and ensure that the reinforcement device can effectively play an anti-buckling role for a long time.

[0025] S3. Use fasteners 2 to connect the connecting plate 301 and the limiting plate 302 to the transmission tower angle steel 1. At the same time, the connecting plate 301 and the limiting plate 302 are also connected by fasteners 2 to ensure a firm connection. The tightening degree of fasteners 2 must meet the design requirements to avoid loosening. The connecting plate 301, the limiting plate 302 and the transmission tower angle steel 1 are connected by fasteners 2 to form an integral structure, which can effectively transmit and disperse external forces, enhance the stability of the transmission tower angle steel, and prevent it from buckling. Ensure that the tightening degree of fasteners 2 meets the design requirements to avoid loosening during use. If the fasteners are loose, stress concentration will occur at the connection parts, reducing the reinforcement effect and even causing safety hazards. Tightening the fasteners strictly in accordance with the design requirements can ensure that the reinforcement device always maintains good performance and stability during long-term use.

[0026] S4. Fix the reinforcing plate 1 303 equipped with the reinforcing plate 306, the auxiliary plate 307 and the extension plate 304 to one of the limit plates 302. First, the arc surface of the reinforcing plate 2 305 contacts the arc surface of the guide plate 404. At this time, the reinforcing plate 1 303 squeezes the guide plate 404, and the guide plate 404 moves the compression spring 403. At the same time, the internal through hole of the guide plate 404 slides with the guide rod 402 to provide a guiding effect. When the concave surface of the reinforcing plate 306 is completely in contact with one of the limit plates 302, the reinforcing plate 2 305 is fixed to the other limit plate 302 by the fastener 1 2. On the plate 302; the reinforcing plate 303 equipped with the reinforcing plate 306, the auxiliary plate 307 and the extension plate 304 is fixed to the limiting plate 302, which enhances the strength of the reinforcing device at a specific position. At the same time, the synergistic effect of various components can better disperse the stress and improve the reinforcement effect. When the arc surface of the reinforcing plate 2 305 contacts the guide plate 404, the movement of the guide plate 404 and the sliding of the guide rod 402 provide precise guidance for the installation of the reinforcing plate 303, which can ensure that the reinforcing plate 303 can be accurately installed to the predetermined position, avoid installation deviation, and improve installation accuracy and quality.

[0027] S5. According to the distance between the two limit plates 302, the reinforcing plate 2 305 equipped with the reinforcing plate 306 and the auxiliary plate 307 is fixed to the other limit plate 302. First, the arc surface of the reinforcing plate 2 305 contacts the arc surface of the guide plate 404. At this time, the reinforcing plate 1 303 squeezes the guide plate 404, and the guide plate 404 moves the compression spring 403. At the same time, the internal through hole of the guide plate 404 slides and slides with the guide rod 402 to provide a guiding effect. When the concave surface of the reinforcing plate 306 is completely in contact with the other limit plate 302, the reinforcing plate 2 305 is fixed to the other limit plate 302 by the fastener 1 2, and then the extension groove 3011 fits the extension plate 3 04, at this time, the extension plate 304 and the reinforcement plate 2 305 are fixed by the fastener 2 3010; the reinforcement plate 2 305 is installed according to the distance between the two limit plates 302, so that the reinforcement device can better adapt to the transmission tower angle steels 1 of different specifications, thereby improving the versatility and adaptability of the reinforcement device. Similar to the reinforcement plate 1 303, the installation of the reinforcement plate 2 305 further enhances the strength of the reinforcement device. At the same time, the cooperation of the extension groove 3011 and the extension plate 304 and the fixation of the fastener 2 3010 make the connection between the reinforcement plate 1 303 and the reinforcement plate 2 305 more firm, which can better withstand the external force and improve the stability of the entire reinforcement device.

[0028] S6. When connecting the two transmission tower angle steels 1, insert the connection plate 502 into the connection groove 506 so that the connection plate 502 can slide in the connection groove 506, use fastener 1 2 to connect one side of the connection plate 502 to the fixed plate 501, and the other side to the transmission tower angle steel 1, then rotate the two connecting rods 504 so that the extension plate 1 507 and the extension plate 2 508 are aligned, and connect the installation shell 505 to the extension plate 1 507 and the extension plate 2 508 respectively through fastener 1 2, thereby completing the assembly of the connection reinforcement mechanism 5, and finally, connect one end of the two transmission tower angle steels 1 through the connection seat 1 509, and the other end through the connection seat 2 5010, to ensure that the entire The integrity and stability of the device, connecting the two transmission tower angle steels 1 through the connecting reinforcement mechanism 5, enhances the overall structural stability of the tower, the sliding design of the connecting plate 502 in the connecting groove 506 and the connection method of the connecting rod 504 and the extension plate, enable the connecting reinforcement mechanism 5 to adapt to different installation conditions and angle steel deformation conditions, improve the flexibility and reliability of the connection, the connection between the connecting seat 1 509 and the connecting seat 2 5010 ensures the connection firmness of the two transmission tower angle steels 1 at both ends, further improves the integrity and stability of the entire device, during the operation of the tower, this stable connection can effectively resist various external forces and ensure the safe operation of the transmission line.
