[0029] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] like Figure 1-4 As shown, this embodiment proposes a pipeline water maintenance device that can adapt to different pipe diameters, which includes:

[0031] A bendable chain belt 1, which is formed by a plurality of sets of hinged chain plates 1a, and under the action of the chain plates 1a, the chain belt 1 can be bent to form a ring structure with one end overlapping the other;

[0032] A strap 2 connected to the tail of the chain belt 1. In some embodiments, the strap 2 is a braided flat belt. The strap 2 is wrapped around the chain belt 1 once so that the chain belt 1 is overlapped end to end and then connected with a tightener 3 for tightening the strap 2. The tightener 3 is located at the tail of the chain belt 1 to fasten the chain belt 1 to the outer wall of the pipeline to be repaired.

[0033] It also includes a prefabricated rubber gasket 4, which is connected end to end to form a ring structure and is placed in the inner ring of the chain belt 1; before the water stopping work, the circumference of the pipeline to be repaired is measured in advance, and the rubber gasket of the corresponding length is cut, and then the prefabricated rubber gasket 4 is placed in the inner ring of the chain belt 1 by bonding or other methods. It can be used to block the joints of two pipelines to prevent water leakage and other phenomena.

[0034] In this embodiment, the chain belt 1 is pre-bent and placed in a circular shape on the outer wall of the pipeline to be repaired, and the tightener 3 is used to pre-tighten the belt 2 so that the prefabricated rubber gasket 4 is initially attached to the outer wall of the pipeline to be repaired. Then, the chain belt 1 is quickly moved horizontally to be placed at the place to be blocked, and the tightener 3 is quickly controlled to tighten the belt 2. Under the action of the belt 2, the chain belt 1 is fastened to the outer wall of the pipeline to be repaired, and the prefabricated rubber gasket 4 is placed between the pipeline to be repaired and the chain belt 1. The tightening force of the chain belt 1 blocks the leaking part, thereby realizing water-carrying repair for different pipe diameters. In the prior art, repairs in the form of clamps require a large number of clamps of different diameters to be prepared in advance, which consumes too much cost and may cause most of the prepared packages to be scrapped due to long-term non-use. This design can be applied to pipes of different diameters, with a wide range of applications. When encountering a special large-diameter pipe, the chain plate 1a can be appropriately added to carry out water-carrying repairs on the special large pipe.

[0035] It is worth noting that the prefabricated rubber gasket 4 inside the overlapping part of the chain belt 1 can be provided with a raised rubber block. The chain belt 1 overlapped on top squeezes the raised rubber block during the tightening process, so that the prefabricated rubber gasket 4 is tightly attached to the leaking part through the rubber block.

[0036] In some embodiments, it also includes several groups of pressing components arranged on the chain plate 1a for pressing the prefabricated rubber gasket 4, the pressing component includes a shell 5, a pressing seat 6 freely penetrating the chain plate 1a is arranged in the shell 5, the bottom of the pressing seat 6 is used to press the prefabricated rubber gasket 4, and also includes a pressing unit 7 arranged in the shell 5 for pressing the pressing seat 6 downward; the prefabricated rubber gasket 4 is pressed together by the pressing seats 6 on the several groups of chain plates 1a, so that the prefabricated rubber gasket 4 further blocks the leaking area, and the prefabricated rubber gasket 4 is made to fit more closely to the outer wall of the pipeline to be repaired through the annular pressure, thereby improving its sealing effect.

[0037] Furthermore, a through hole 8 is provided on the chain plate 1a, and the pressure seat 6 includes an upper pressure plate 61 that can contact the lower pressure unit 7 and a lower pressure plate 62 for pressing the prefabricated rubber gasket 4. A sliding rod 63 is commonly connected between the upper pressure plate 61 and the lower pressure plate 62, and the sliding rod 63 is set to slide up and down in the through hole 8. This design makes it convenient for the lower pressure unit 7 to press the pressure seat 6, limit the pressure seat 6 to a certain extent, and further increase the contact area between the bottom surface of the pressure seat 6 and the prefabricated rubber gasket 4, thereby further improving the pressing effect.

[0038] In some embodiments, the pressing unit 7 includes a rotatable gradual cam 71 disposed in the housing 5, a side wall of the gradual cam 71 is provided with an anti-reverse tooth 72, and also includes a ratchet 73 disposed on one side of the gradual cam 71 and matched with the anti-reverse tooth 72; a slide slot 74 is provided on the upper side of the housing 5, and connecting rods 75 are connected to both ends of the gradual cam 71, and the two connecting rods 75 are connected to a handle 76 after extending out of the slide slot 74. In this embodiment, the gradual cam 71 is driven to rotate by pulling the handle 76, and the protruding component squeezes the pressure seat 6 during the rotation, and the pressure seat 6 applies the force to the prefabricated rubber gasket 4 to further block the water leakage; further, when the handle 76 drives the gradual cam 71 to rotate and squeeze to a certain extent, the ratchet 73 clamps the anti-reverse tooth 72 to prevent the gradual cam 71 from being reset by the reaction force.

[0039] Furthermore, a plane is provided at the end of the protruding portion of the gradual cam 71, and the plane is in contact with the top surface of the pressure seat 6. The plane is more stable during the process of pressing the pressure seat 6, and can effectively prevent the reaction force brought by the pressure seat 6 from causing the gradual cam 71 to reset.

[0040] In some embodiments, a plug hole 77 is provided on the handle 76, and the strap 2 can freely pass through the plug hole 77 and drive the handle 76 to rotate; specifically, a plurality of groups of limit posts 9 are connected to the strap 2, and the limit posts 9 are located behind (on the right side of) the through hole 8. This design realizes the rotation of the gradual cam 71 during the process of tightening the strap 2 through the tightener 3, which is convenient for operating a plurality of groups of holding components at one time, saving the procedure of rotating the handle 76 separately, and making the whole process of pipeline water maintenance quick and fast.

[0041] The method of using this device is as follows:

[0042] S1: According to the actual situation of the pipeline to be repaired, a suitable rubber gasket is prefabricated and placed on the inner ring of the chain belt 1 by bonding or other methods;

[0043] S2: Wrap the chain belt 1 around the pipe to be repaired, and preliminarily pre-tighten the belt 2 through the tightener 3;

[0044] S3: Quickly slide the chain belt 1 to the leaking part of the pipe, and tighten the belt 2 through the tightener 3, so that the chain belt 1 and the prefabricated rubber gasket 4 inside are fixed on the pipe to be repaired, close to the leaking part to seal it;

[0045] In S3, while tightening the strap 2, the strap 2 pulls the handle 76, and the handle 76 drives the gradual cam 71 to rotate, so that the raised portion of the gradual cam 71 presses down the pressure seat 6, and the pressure seat 6 further presses down the prefabricated rubber gasket 4. The annular pressure makes the prefabricated rubber gasket 4 fit more closely to the outer wall of the pipe to be repaired, thereby improving its sealing effect.

[0046] In some embodiments, to deal with a long horizontal leak, such as Figure 5 As shown, two groups of maintenance devices can be set up, and several groups of waterproof boards are connected between the two chain belts 1 in the two groups of maintenance devices by welding or other methods, and prefabricated rubber gaskets 4 are set on the inner circle of the waterproof board. The outer wall of the waterproof board is connected with a wider tie belt 2, and the tie belt 2 is connected with a tightener 3 after it is wrapped around the waterproof board. The tightener 3 is connected to the top of the waterproof board. In actual use, the prefabricated rubber gasket 4 is fixed to the chain belt 1 and the inner circle of the waterproof board by bonding or other methods, and the two chain belts 1 and the waterproof board are wrapped around the pipeline to be repaired for preliminary pre-tightening, and they are quickly moved to the leaking port, and the leaking port is initially blocked by the waterproof board and the prefabricated rubber gasket 4, and then the three groups of tighteners 3 are quickly tightened. When the tightener 3 tightens the tie belt 2, the tie belt 2 further tightens the chain belt 1 and the waterproof board, so that the prefabricated rubber gasket 4 inside it is completely blocked and fits the leaking port, and the horizontal leaking port is completely blocked.
