[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 This utility model provides a technical solution: a device for repairing partial deformation of drainage pipes, including a repair device body 1. The repair device body 1 includes a cross base 2, an arc plate 3, a rotating arm 4, a connecting sleeve 5, a chain link 6, and a fixing buckle 7. The center of the cross base 2 is provided with a through groove 8 for installing the connecting sleeve 5. One end of the connecting sleeve 5 is fixedly connected to the through groove 8. The inside of the connecting sleeve 5 is provided with an installation groove 9 for installing the fixing buckle 7. The rotating arm 4 is rotatably connected to the periphery of the cross base 2. The other end of the rotating arm 4 is fixedly connected to the arc plate 3. The arc plate 3 is used to support the drainage pipe. The fixing buckle 7 is provided with chain links 6 on its periphery. A fixing block 10 for connecting the arc plate 3 is provided between two chain links 6. The fixing block 10 is connected to the fixing buckle 7 through the chain links 6 to form an adjustable support structure. A jack 11 for driving the support structure is also installed inside the connecting sleeve 5.

[0027] Specifically, the cross base 2 has several first mounting holes 12 around its periphery. The rotating arm 4 is connected to the first mounting holes 12 via first T-pins 13. Furthermore, the fixing buckle 7 has second mounting holes 14 around its periphery. One side of the chain link 6 has a first connecting hole 16 that mates with the second mounting hole 14. The chain link 6 is connected to the second mounting hole 14 via a second T-pin 15, and the other end of the second T-pin 15 is connected to the first connecting hole 16. Further, one side of the chain link 6 also has a second connecting hole 17. The fixing block 10 has a first insertion hole 18 that mates with the second connecting hole 17. The first insertion hole 18 and the second connecting hole 17 are connected by a third T-pin 19. These features make the entire device more stable and the connection between the chain link 6, the fixing block 10, and the fixing buckle 7 more flexible and reliable. In practical use, the angle of the rotating arm 4 and the position of the arc plate 3 can be adjusted according to the degree and location of local deformation of the drainage pipe, so that the arc plate 3 can fit tightly against the inner wall of the drainage pipe, achieving effective support and repair. Meanwhile, the driving action of the jack 11 can further increase the supporting force of the arc plate 3 on the drainage pipe, ensuring the repair effect. In addition, the first T-pin 13, the second T-pin 15 and the third T-pin 19 can be set to facilitate the disassembly and assembly of various components, which is convenient for the transportation and storage of the device, and also improves the versatility and applicability of the device.

[0028] Specifically, the included angle between the two inclined sides of the arc-shaped plate 3 is 70°, and the inner curvature of the arc-shaped plate 3 is 12.5°. This design allows the arc-shaped plate 3 to better adapt to drainage pipes of different diameters and degrees of deformation, improving the device's adaptability and repair effectiveness. In actual operation, workers can select and adjust the appropriate arc-shaped plate 3 according to the actual condition of the drainage pipe, ensuring a tight fit between the arc-shaped plate 3 and the inner wall of the drainage pipe, thereby achieving the best supporting repair effect.

[0029] Specifically, the top of the rotating arm 4 is inclined along the inner side of the arc plate 3 at the connection point with the arc plate 3. Through the above setting, the connection between the rotating arm 4 and the arc plate 3 is more stable. At the same time, when supporting the drainage pipe, the rotating arm 4 can better transmit the supporting force generated by the jack 11, thereby improving the supporting effect and stability of the entire device.

[0030] Specifically, the surface of the curved plate 3 is provided with an anti-slip layer 20, which is made of rubber. The anti-slip layer 20 is used to increase the friction between the curved plate 3 and the drainage pipe. By setting the anti-slip layer 20, the curved plate 3 is less likely to slide or shift when supporting the drainage pipe, thus further ensuring the stability and effectiveness of the repair.

[0031] A specific application example of this embodiment is as follows:

[0032] When using this device, firstly, by observing the degree and location of local deformation in the drainage pipe, the angle of the rotating arm 4 and the position of the arc plate 3 are adjusted. During the adjustment process, the flexibility of the first T-pin 13, the second T-pin 15, and the third T-pin 19 can be used to easily disassemble and assemble various components to adapt to drainage pipes with different degrees of deformation. Then, the worker needs to transport the repair device body 1 to the location of the drainage pipe to be repaired. After the arc plate 3 is tightly attached to the inner wall of the drainage pipe, the jack 11 is activated. The driving action of the jack 11 increases the supporting force of the arc plate 3 on the drainage pipe, achieving effective supporting repair. Throughout the repair process, the worker can observe the changes in the drainage pipe and the working status of the repair device, and adjust the position of the arc plate 3 and the magnitude of the supporting force at any time to ensure the best repair effect. After the repair is completed, the repair device body 1 can be easily disassembled for the next repair task. The drainage pipe local deformation repair device of this embodiment has a simple structure, is easy to operate, and has strong adaptability. It can effectively repair the local deformation problem of drainage pipes and improve the use effect and safety of drainage pipes.
