[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] Please see the attached Figure 1 -Attached Figure 4 The present invention provides a power transmission and transformation line repair tower. In this embodiment, the tower is provided with multiple fixing rings 21 on the tower body to achieve rapid and stable traction adjustment. Specifically, one end of the traction cable 4 is fixedly connected to one side of the outer wall of the fixing ring 21, and the other end of the traction cable 4 is hooked to the fixing ring 21 via a spring hook 22. This design allows the traction cable 4 to be quickly and reliably connected to the tower body. When the tower body angle needs to be adjusted, the traction force of the traction cable 4 allows the tower body to achieve flexible angle adjustment.

[0025] Furthermore, the tower's bottom structural design ensures its stability and robustness. The tops of Tower 1 and Tower 2 are fixedly connected to a base plate 3, which is connected to the base 6 via highly symmetrical connecting plates 16 and 2, respectively. Ground nuts 20 are fixed to both sides of the base 6, securing it firmly to the ground and ensuring the overall structural stability.

[0026] Connecting plate 16 is fixed to the bottom of base plate 3 and further reinforced by supporting plate 2 17. The top of supporting plate 2 17 is fixedly connected to base plate 3. This effectively strengthens the connection between base plate 3 and connecting plate 16, thereby enhancing the stability of base plate 3. Connecting plate 2 19 is fixed to the top of base 6 and further reinforced by supporting plate 1 15. The bottom of supporting plate 15 is fixedly connected to the top of base 6, thus strengthening the connection between base 6 and connecting plate 2 19 and making the entire structure more solid and reliable.

[0027] Connecting plate 16 and connecting plate 2 19 are connected by a rotating shaft 18. This design allows the base plate 3 and base 6 to rotate relative to each other through connecting plates 16 and 2 19. With this structural design, when the tower body needs to be adjusted in angle, the traction cable 4 hooks onto the fixing ring 21 through the spring hook 22 on the fixing ring 21 and applies traction, allowing the tower body to adjust its angle as needed. This design not only increases the flexibility of the tower body but also allows for faster adjustments during emergency repairs, improving both efficiency and safety.

[0028] In summary, the power transmission and transformation line repair tower of the utility model realizes the rapid installation and stable connection of the tower body through ingenious structural design, and at the same time has a flexible angle adjustment function, which is suitable for various complex repair environments and provides a strong guarantee for the rapid repair of power transmission and transformation lines.

[0029] There are multiple cross beams 1 7 fixedly connected inside the tower body 1, and there are multiple cross beams 2 8 fixedly connected inside the tower body 2. The top of the top cross beam 1 7 is fitted with the bottom of the bottom cross beam 2 8. The inner wall of the cross beam 2 8 is fixedly connected with a splicing plate 1 9, and the inner wall of the cross beam 7 is fixedly connected with a splicing plate 2 10. The bottom of the splicing plate 1 9 is fitted with the inner wall of the splicing plate 2 10. The top of the splicing plate 1 9 and the bottom of the splicing plate 2 10 are both fixedly connected with a rectangular array of fixed plate 1 1. The top of the splicing plate 1 9 and the bottom of the splicing plate 2 10 are both fixedly connected with a rectangular array of fixed plate 2. Fixed columns 13 are fixedly connected between the fixed plates 2 12 on both sides. The outer wall of the tower body 1 is fixedly connected with a rectangular array of side package plates 14, and one side of the inner wall of the side package plate 14 is fixedly connected to one side of the outer wall of the tower body 2 2.

[0030] When beam 1 (7) at the top of tower body 1 is aligned and fitted with beam 2 (8) at the bottom of tower body 2 (2), ensure that the mating surfaces are in close contact, with no noticeable gaps. During the fitting process, a temporary fixture can be used to maintain the relative position of beams 1 (7) and 2 (8) to prevent displacement during subsequent operations. Splice plate 1 (9) inside beam 2 (8) is similarly fitted with splice plate 2 (10) inside beam 1 (7). The bottom of splice plate 1 (9) is in close contact with the inner wall of splice plate 2 (10), ensuring a smooth, seamless contact surface.

[0031] On the opposite side of the outer wall of splicing plate 1 9 and splicing plate 2 10, set fixing plate 11. Fixing plate 11 should be evenly distributed to ensure that the splicing plate can obtain sufficient support and fixing force on the entire fitting surface. Use screws to pass through fixing plate 11, splicing plate 1 9 and splicing plate 2 10 in sequence. The spacing of the screws should be uniform to ensure that each connection point can provide sufficient fixing force. The length of the screw should be long enough to ensure that it can penetrate all the fixing layers and will not loosen after tightening. Add fixing plate 2 12 on the same outer wall of splicing plate 1 9 and splicing plate 2 10. Fixing plate 2 12 is similar to fixing plate 11 and also needs to be evenly distributed to ensure the fixing effect of the entire splicing plate. Use screws to pass through fixing plate 2 12, splicing plate 1 9 and splicing plate 2 10 and ensure the tightness of the screws. Add fixing columns 13 between the upper and lower fixing plates 2 12. The function of the fixing columns 13 is to increase the stability of the structure and prevent the splicing plate from deforming when subjected to force. The fixing column 13 is connected to the fixing plate 2 12 by screws passing through it, ensuring the tightness and stability of the entire structure. A side panel 14 is installed at the connection between the tower body 1 and the tower body 2 2. The function of the side panel 14 is to protect the connection, prevent the influence of external factors on the connection, and at the same time increase the aesthetics of the overall structure. The side panel 14 is fixed to the connection between the tower body 1 and the tower body 2 2 by four screws. The positions of the screws should be evenly distributed, and the two screws on both sides are fixed inside the tower body 1 and the tower body 2 2 to ensure that the side panel fits tightly to the tower body. Of the two screws on the inside, one passes through the crossbeam 2 8 to be fixed to the tower body 2 2, and the other passes through the crossbeam 1 7 to be fixed to the tower body 1. This fixing method can ensure that the connection between the side panel and the tower body is tighter and not easy to loosen.

[0032] After all fixing operations are completed, a comprehensive inspection is conducted to ensure that every screw is tightened and all splicing plates and fixing plates are not loose. A structural stability test is then conducted to verify that the joints between Tower 1 and Tower 2 are secure and free of shaking by applying a certain external force.
