[0033] Figure 3 This is a schematic diagram of the support mechanism 1 and the winding and tightening mechanism 2 of a water pipeline repair device according to one embodiment of the present disclosure.
[0034] Figure 4 This is a partial structural diagram of the winding and tightening mechanism 2 of a water pipeline repair device according to one embodiment of the present disclosure.
[0035] Figure 5 This is a schematic diagram of the end fixing mechanism 3 of a water pipeline repair device according to one embodiment of the present disclosure.
[0036] like Figures 1-5 As shown, the water pipeline repair device disclosed herein may include components such as a support mechanism 1, a winding and tightening mechanism 2, and an end fixing mechanism 3.
[0037] like Figure 1 As shown, in a preferred embodiment, it also includes a damaged pipe 41, with a repair component 42 attached to the outside of the damaged pipe 41.
[0038] like Figure 2 and Figure 3 As shown in this disclosure, the support mechanism 1 includes a U-shaped frame 11, a handle 12 is fixedly provided on the middle of the outer side of the U-shaped frame 11, arc-shaped fitting grooves 13 are provided at both ends of the U-shaped frame 11, and mounting grooves 14 are provided at both ends of the inner side of the U-shaped frame 11.
[0039] This facilitates the grasping of the handle 12 and the movement of the U-shaped frame 11, thereby allowing the U-shaped frame 11 to adhere to the outside of the damaged pipe 41 through the arc-shaped fitting groove 13.
[0040] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the winding and tensioning mechanism 2 includes a winding column 21 nested inside two mounting slots 14 via bearings and a forward and reverse motor 22 fixedly mounted on the side of the U-shaped frame 11. The forward and reverse motor 22 is connected to the winding column 21. A first through slot 23 is provided through the top of the winding column 21. Guide slopes 24 are provided on the inner sides of the openings at both ends of the first through slot 23. A flexible fixing band 25 with its tail end fixed to the inner side of the second channel 32 is inserted into the inner side of the first through slot 23. The flexible fixing band 25 has a rough surface.
[0041] Therefore, to facilitate the flexible fixing strap 25 to bypass the damaged pipe 41 and insert into the inner side of the first through groove 23, the guide slope 24 guides the head end of the flexible fixing strap 25 during this process, thereby reducing the difficulty of inserting the flexible fixing strap 25 into the inner side of the first through groove 23. Then, the repair piece 42 is inserted between the damaged pipe 41 and the flexible fixing strap 25 and held outside the damaged position of the damaged pipe 41. Then, the forward and reverse motor 22 is connected to an external power source and drives the winding column 21 to rotate in the forward direction. When the winding column 21 rotates, it first winds the excess part at the head end of the flexible fixing strap 25, and then tightens the flexible fixing strap 25 under the action of friction, thereby making the flexible fixing strap 25... 5. Fix the repair component 42 to the outside of the damaged pipe 41. Then, weld the left and right sides of the repair component 42. Then, drive the winding column 21 to rotate in the opposite direction using the forward and reverse motor 22. This will cause the winding column 21 to loosen the tightened flexible fixing band 25. Then, pull the first end of the flexible fixing band 25 out from the inside of the first through groove 23 and remove it from the outside of the damaged pipe 41. Finally, weld the front and back sides of the repair component 42. Compared with the existing technology, it is more convenient to fix the repair component 42 to the outside of the damaged pipe 41. At the same time, due to the characteristics of the flexible fixing band 25, it can fit the outside of the damaged pipe 41 of different specifications. It is more convenient to use and has a wider range of applications.
[0042] In addition, when not in use, the first end of the flexible fixing strap 25 can be inserted into the inside of the first through slot 23, and then the forward and reverse motors 22 can drive the winding column 21 to rotate continuously, so that the flexible fixing strap 25 is wound around the outside of the winding column 21 for storage, thereby reducing the space occupied by the device.
[0043] Furthermore, the rough surface on the outer side of the flexible fixing band 25 creates a large frictional force between adjacent rough surfaces when the winding post 21 drives the head end of the flexible fixing band 25 to rotate. This allows the flexible fixing band 25 to be wound and tensioned without having to manually fix the head end of the flexible fixing band 25 inside the first through groove 23, making it more convenient to use.
[0044] like Figure 5 As shown in this disclosure, the end fixing mechanism 3 includes a fixing post 31 fixedly disposed inside the U-shaped frame 11. A second channel 32 is provided through the top of the fixing post 31. Multiple threaded holes 33 are provided on the side of the fixing post 31. A fixing bolt 34 is threadedly connected to the inside of any one of the threaded holes 33. The tail end of the flexible fixing band 25 is inserted into the inside of the second channel 32. Multiple fixing bolts 34 are pressed against the side of the tail end of the flexible fixing band 25.
[0045] Therefore, when the flexible fixing band 25 needs to be replaced, multiple fixing bolts 34 are rotated in sequence, so that the ends of the fixing bolts 34 no longer press the flexible fixing band 25 against the inner wall of the second channel 32. Then, the flexible fixing band 25 is pulled out from the inside of the second channel 32, and the tail end of the new flexible fixing band 25 is inserted into the inside of the second channel 32 and multiple fixing bolts 34 are tightened in sequence, so that the multiple fixing bolts 34 press the tail end of the new flexible fixing band 25 against the inner wall of the second channel 32 to achieve fixation.
[0046] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0047] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
