Description

Technical Field

[0001] The present application relates to the technical field of power transmission towers, and in particular to a windproof reinforcement component for power transmission towers. Background Art

[0002] Transmission towers are key equipment in high-voltage power transmission systems. They are mainly used to support cables or wires of power transmission lines to ensure that power is transmitted from power plants to various user terminals. They are usually built near power plants and distribution stations in the wild. At present, transmission towers are built in open outdoor locations for use. Due to their certain height, they usually need to be reinforced to prevent wind.

[0003] After searching, the patent document with authorization announcement number CN221568064U announced an electric tower reinforcement device, which includes a transmission tower and a base. A groove is opened on the top of the base, and the transmission tower is fixedly connected to the inner wall of the groove. Four moving blocks are slidably installed on the bottom inner wall of the groove. Threaded rods are rotatably installed on the four sides of the base. The four moving blocks are threadedly connected to the outside of the four threaded rods. Manual mechanisms are provided on the outside of the four threaded rods. Shock-absorbing reinforcement mechanisms are rotatably installed on the top of the four moving blocks. By adjusting the positions of the four shock-absorbing rods, the transmission tower is pressed and fixed to improve the stability of the transmission tower.

[0004] In the prior art, when the transmission tower is reinforced against wind, most of them are reinforced against wind by adding counterweights or installing inclined steel cables from the external space of the transmission tower, but there is no structure for secondary wind reinforcement from the internal space of the transmission tower, resulting in poor wind-proof reinforcement effect of the transmission tower. When encountering complex and changeable strong wind environment, these existing reinforcement methods are difficult to provide all-round, accurate and efficient protection for the transmission tower.

[0005] Therefore, we propose a wind-proof reinforcement component for a transmission tower to solve the above problems. Utility Model Content

The four ends of the multiple cross-shaped lifting seats 7 slide through the corresponding strip holes 8 respectively. The four ends of the multiple cross-shaped lifting seats 7 are fixedly connected with a reinforcing wire rope 9. One end of the four reinforcing wire ropes 9 on the same cross-shaped lifting seat 7 is fixedly connected to the inner walls of the front, back, left, and right sides of the transmission tower 2 respectively. The bottom end of the screw rod 5 at the bottom is fixedly installed with a vertical shaft 10. The top of the bearing base 1 is provided with a circular groove 1 located directly below the assembly plate 3. 2, the bottom end of the hollow column 4 passes through the assembly plate 3 and extends into the circular groove 12, a motor 13 is fixedly installed on the bottom inner wall of the circular groove 12, the bottom end of the vertical shaft 10 extends to the outside of the hollow column 4 and is fixedly connected to the output shaft end of the motor 13, the vertical shaft 10 is driven to rotate by the motor 13, and then the multiple screw rods 5 and the multiple connecting rods 6 can be driven to rotate synchronously at the same time, so that the cross-shaped lifting seat 7 threadedly mounted on the screw rod 5 moves up and down along the strip hole 8 on the outer wall of the hollow column 4, and the multiple reinforcement wire ropes 9 can be adjusted. To a straightened state, this design can effectively reinforce the internal space of the transmission tower 2, effectively enhancing the pertinence and adaptability of the windproof reinforcement of the transmission tower 2. By utilizing multiple cross-shaped lifting seats 7 and reinforcing steel wire ropes 9 connected at four ends thereof, an all-round pulling support reinforcement for the interior of the transmission tower can be formed. It should be noted that the motor 13 adopts a forward and reverse-transformable motor, and its line connection method and control method are mature technologies in this field, which are fully disclosed and therefore will not be elaborated in this article.

[0025] In this embodiment, a shaft seat 11 is fixedly installed on the top inner wall of the hollow column 4, and the top end of the screw rod 5 located at the top is rotatably connected to the shaft seat 11, ensuring the stability of the motor 13 driving the vertical shaft 10, multiple screw rods 5 and multiple connecting rods 6 to rotate synchronously at the same time. The diameters of the multiple screw rods 5 are set to the same size, and the shapes and sizes of the multiple cross-shaped lifting seats 7 are set to the same size, ensuring that the multiple cross-shaped lifting seats 7 can be raised or lowered synchronously.

[0026] In this embodiment, four evenly distributed fixed pulleys 15 are rotatably installed on the top of the bearing base 1, four evenly distributed installation grooves 14 are opened on the inner side wall of the circular groove 12, and fixed pulleys 16 are rotatably installed on the bottom inner wall of the four installation grooves 14. Four bearings 17 are fixedly installed on the bottom inner wall of the circular groove 12. The four bearings 17 are evenly distributed with the motor 13 as the center. A rotating shaft 18 is rotatably installed on the top of the four bearings 17. An I-shaped winding wheel 19 is fixedly installed on the top of the four rotating shafts 18. A reinforced steel wire rope 20 is wound on the four I-shaped winding wheels 19. One end of the reinforced steel wire rope 20 passes around the fixed pulley 16 and the fixed pulley 15 in turn and is fixedly connected to the outer wall of one side of the transmission tower 2. The four I-shaped winding wheels 19 A driven gear 21 is fixedly installed on the top, and a driving gear 22 is fixedly mounted on the vertical shaft 10. The four driven gears 21 are meshed with the driving gear 22. The diameters of the four driven gears 21 are set to be the same. By utilizing the meshing transmission effect of the four driven gears 21 with the same diameter and the driving gear 22, it can be ensured that the four I-shaped winding wheels 19 rotate in the same direction at the same time, and the synchronous retraction and release of the four reinforcement steel wire ropes 20 can be achieved, and the four reinforcement steel wire ropes 20 can be adjusted to a straight state. This design can achieve effective reinforcement from the external space of the transmission tower 2, and this synchronous operation mode ensures that the transmission tower 2 is evenly stressed all around, avoids structural deformation or damage caused by inconsistent reinforcement strength on one side, and improves the overall reliability and stability of the reinforced windproof system.

[0027] In this embodiment, an inclined avoidance hole 23 is opened on the top inner wall of the installation groove 14, and the reinforcement wire rope 20 moves through the avoidance hole 23. The inclined avoidance hole 23 is utilized to guide the reinforcement wire rope 20 reasonably during the movement, thereby avoiding friction and interference with the top inner wall of the installation groove 14, extending the service life of the reinforcement wire rope 20, and also ensuring its smoothness during the retraction and release process, further improving the reliability and stability of the windproof reinforcement system.

[0028] Through the above structure, the transmission tower windproof reinforcement assembly provided by the present application is:

[0029] The control motor 13 is operated, and its output shaft drives the vertical shaft 10 connected thereto to rotate, and the vertical shaft 10 drives the multiple lead screws 5 and the multiple connecting rods 6 to rotate synchronously. During the simultaneous rotation of the multiple lead screws 5, the cross-shaped lifting seat 7 threadedly mounted on the lead screws 5 cannot rotate with the lead screws 5 due to the limitation of the strip holes 8 on the outer wall of the hollow column 4, that is, the multiple cross-shaped lifting seats 7 can only slide up and down along the strip holes 8 at the same time. In this way, the height position of the cross-shaped lifting seat 7 on the hollow column 4 can be adjusted according to actual needs, and the reinforcing steel wire rope 9 connected to the four ends of the cross-shaped lifting seat 7 can be adjusted to a straight state, thereby realizing all-round pulling support reinforcement from the internal space of the transmission tower 2 to enhance the windproof effect.

[0030] When the motor 13 drives the vertical shaft 10 to rotate, the driving gear 22 fixedly mounted on the vertical shaft 10 rotates with the vertical shaft 10, and the four driven gears 21 meshing with the driving gear 22 also rotate synchronously, so that the four driven gears 21 rotate in the same direction, and the four I-shaped winding wheels 19 rotate with the corresponding driven gears 21. When the I-shaped winding wheel 19 rotates, under the guidance of the fixed pulley 2 16 and the fixed pulley 1 15, the reinforcement wire rope 2 20 wound thereon begins to be retracted and released, and then the four reinforcement wire ropes 2 20 can be adjusted to a straight state at the same time, thereby realizing the pulling, supporting and reinforcing of the transmission tower 2 from the external space of the transmission tower 2, and ensuring that the force on all sides of the transmission tower 2 is uniform, further improving the overall reliability and stability of the reinforced wind protection system.
