Description

Technical Field

[0001] This utility model relates to the technical field of pipeline leak repair devices, specifically a leak-sealing device for urban water supply pipelines. Background Technology

[0002] In the maintenance of urban water supply pipelines, leaks and damage are frequently encountered. When repairing leaks, it is necessary to shut off the water supply to the pipeline beforehand, then seal the leak, or cut off the leak and reconnect it with a straight connector. This method of leak sealing and repair not only affects users' normal water use during the maintenance process, but also makes the process complex and reduces the efficiency of pipeline repair. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a leak-sealing device for urban water supply pipelines.

[0004] The technical solution of this utility model is as follows:

[0005] A leak-sealing device for urban water supply pipelines is used to seal perforated holes in water supply pipelines. As the core technical concept of this utility model, the leak-sealing device (the aforementioned leak-sealing device for urban water supply pipelines) includes a first fixing member, a second fixing member, and a strip strap disposed between the two fixing members. The strap is made of rubber and can be wrapped around the leaking hole in the pipeline. A connecting bolt is provided between the two fixing members, which can fix the two fixing members. Then, the strap is used to tighten the leaking hole, thereby sealing the leak.

[0006] Specifically, the first fixing member includes a middle rod and first connectors at both ends, and the second fixing member includes a strip-shaped fixing block and second connectors at both ends. The strap is fixed to the middle of the middle rod and the fixing block. There are two connecting bolts, which are respectively located between the first connector and the second connector on the same side. By wrapping the strap around the leak in the pipe and rotating the connecting bolt, the distance between the two fixing members can be adjusted, thereby driving the strap to tighten the leak and seal it. The sealing process does not affect the user's normal water use and does not require shutting down the water supply, making the leak sealing process simpler and faster.

[0007] As described above, in a preferred embodiment of the urban water supply pipeline sealing device, in order to ensure that the connecting bolt can better cooperate with the two connecting heads, and thus ensure that the binding strap can be tightened better under the action of the connecting bolt, the second connecting head is rotatably located at the end of the fixing block.

[0008] As a further preferred embodiment, in order to ensure the binding effect of the cable tie on the tightened position and thus ensure the sealing effect of the leak, the cable tie is arranged to bypass the middle rod and both ends are fixed to the fixing block.

[0009] As described above, in a preferred embodiment of the urban water supply pipeline leak sealing device, the fixing block has a strip-shaped through hole in the middle, the end of the strap passes through the through hole, and the outer side of the fixing block is provided with a tightening bolt that can abut against the strap inside the through hole. Based on this, the length of the strap between the two fixing parts can be adjusted according to the pipe diameter, which significantly improves the applicability of the sealing device.

[0010] Furthermore, to ensure the fixing effect of the strap and the second fastener, and thus to ensure that the strap can be tightened better through the cooperation of the second fastener and the first fastener, the length of the through hole is adapted to the width of the strap, and the width is twice the thickness of the strap.

[0011] As a further preferred embodiment, in order to ensure the fixing effect of the strap in the through hole, and at the same time not to affect the normal adjustment of the strap length between the two fasteners, the tightening bolt passes through the outer strap near it and abuts against the inner strap.

[0012] Preferably, to further ensure the secure fastening of the strap and the second fastener, multiple tightening bolts are arranged linearly along the length of the through hole.

[0013] As described above, in a leak-sealing device for urban water supply pipelines, the first connector includes a columnar baffle at the end of the intermediate rod and a first connecting block on the outside of the baffle. The connecting bolt passes through the first connecting block. To ensure the fixing effect of the strap on the first fixing member, and thus to ensure that the strap can be better tightened through the cooperation of the first fixing member and the second fixing member, the length of the intermediate rod is adapted to the width of the strap, and the outer diameter of the baffle is larger than the outer diameter of the intermediate rod.

[0014] The beneficial effects of this utility model are as follows: This utility model is a leak-sealing device for urban water supply pipelines. The strap is made of rubber. By wrapping the strap around the leak in the pipeline and rotating the connecting bolt, the distance between the two fixing parts can be adjusted, thereby driving the strap to tighten the leak and seal it. The sealing process does not affect the user's normal water use, and there is no need to shut down the pipeline, making the leak sealing process simpler and faster. Attached Figure Description

[0024] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0025] Example

[0026] This embodiment provides a leak-sealing device for urban water supply pipelines, used for sealing perforated leaks in water supply pipelines 1. (See attached image) Figures 1-3 The leak-sealing device 2 includes a first fixing member 21, a second fixing member 22, and a strip strap 23 disposed between the two fixing members. Through the cooperation of the two fixing members and the strap 23, the leak on the pipeline 1 can be sealed. The structure of the leak-sealing device 2 will be described in detail below with reference to the accompanying drawings.

[0027] In this embodiment, the core technical concept of this utility model is combined with Figure 5 The strap 23 is made of rubber and can be wrapped around the leak in the pipe 1. A connecting bolt 24 is provided between the two fixing parts. The two fixing parts can be fixed by the connecting bolt 24, and the leak can be tightened by the strap 23 to seal the leak.

[0028] Specifically, combining Figure 4The first fixing member 21 includes a middle rod and first connectors 211 at both ends. The second fixing member 22 includes a strip-shaped fixing block 221 and second connectors 223 at both ends. The strap 23 is fixed to the middle part of the middle rod and the fixing block 221. There are two connecting bolts 24, which are respectively located between the first connectors 211 and the second connectors 223 on the same side. By wrapping the strap 23 around the leak in the pipe 1 and rotating the connecting bolts 24, the distance between the two fixing blocks 221 can be adjusted, thereby driving the strap 23 to tighten the leak and seal it. The sealing process does not affect the user's normal water use, and there is no need to shut down the water supply to the pipe 1, making the leak sealing process simpler and faster.

[0029] It should be noted that when using the leak-sealing device 2 of this embodiment to seal leaks, the size of the leak should be smaller than the width of the strap 23. That is, the leak-sealing device 2 of this embodiment is suitable for sealing smaller leaks on the pipeline 1. For pipelines with larger leaks, it is not necessary to use the leak-sealing device 2 of this embodiment to seal them.

[0030] In this embodiment, as a preferred implementation, in order to ensure the binding effect of the cable tie on the tightened position and thus ensure the sealing effect of the leak, the cable tie 23 is arranged to bypass the middle rod, and both ends are fixed to the fixing block 221.

[0031] Specifically, the first connector 211 includes a columnar stop at the end of the intermediate rod and a first connecting block on the outside of the stop. The connecting bolt 24 passes through the first connecting block and is spirally connected to the second connector 223. Based on the above structure, in order to ensure the fixing effect of the strap 23 on the first fixing member 21, and thus ensure that the strap 23 can be better tightened by the cooperation of the first fixing member 21 and the second fixing member 22, the length of the intermediate rod is adapted to the width of the strap 23, and the outer diameter of the stop is larger than the outer diameter of the intermediate rod, so that the inner side of the stop can fit against the two sides of the strap 23 to limit the strap 23.

[0032] In this embodiment, as a preferred implementation, the middle part of the fixing block 221 is provided with a strip-shaped through hole along its length direction. The through hole extends through the thickness direction of the fixing block 221. Both ends of the strap 23 pass through the through hole. The outer side of the fixing block 221 is provided with a tightening bolt 222 that can abut against the strap 23 in the through hole. Based on this, the length of the strap 23 between the two fixing parts can be adjusted according to the pipe diameter of the pipeline 1, which significantly improves the applicability of the sealing device.

[0033] As a preferred embodiment, in order to ensure the fixing effect of the strap 23 and the second fastener 22, and thus ensure that the strap 23 can be better tightened by the cooperation of the second fastener 22 and the first fastener 21, the length of the through hole along the length direction of the fixing block 221 is adapted to the width of the strap 23, and the width is twice the thickness of the strap 23, that is, the cross-sectional specifications of the through hole are adapted to the cross-sectional specifications of the two layers of strap 23.

[0034] As a further preferred embodiment, in order to ensure the fixing effect of the strap 23 in the through hole, and at the same time not to affect the normal adjustment of the length of the strap 23 between the two fasteners, the tightening bolt 222 passes through the outer strap 23 close to it and abuts against the inner strap 23.

[0035] Preferably, in order to ensure that the connecting bolt 24 can better cooperate with the two connectors, and thus ensure that the strap 23 can be tightened better under the action of the connecting bolt 24, the second connector 223 is rotatably disposed at the end of the fixing block 221. Specifically, the second connector 223 includes a turntable rotatably disposed at the outer end of the fixing block, and a second connector is provided on the outer side of the turntable. The connecting bolt 24 passes through the first connector and is spirally connected to the second connector.

[0036] Furthermore, to further ensure the secure fastening of the strap 23 to the second fastener 22, multiple tightening bolts 222 are arranged linearly along the length of the through hole.
