Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, and in particular relates to a pipeline leak sealing device for municipal engineering. Background Technology

[0002] Municipal engineering pipelines are widely used in the transportation of fluid substances. During use, defects such as cracks and pinholes may appear on the pipeline, causing leakage of fluid substances. As the leakage continues, the leak will become larger and larger. Especially when the pressure inside the pipeline is high, it may even cause the pipeline to burst. In some cases where it is inconvenient to shut down or isolate the pipeline, it is necessary to quickly plug the leak.

[0003] Commonly used pipe sealing devices on the market consist of two fasteners. These fasteners are tightened onto the pipe, and nuts are used to reinforce the tightness. However, in practical applications, because the fasteners are in direct contact with the pipe surface, moisture can easily accumulate in the contact area, especially when the pipe is uneven. This moisture accumulation not only affects the sealing effect but also accelerates the corrosion process on the pipe surface, reducing the long-term safety of the pipe. In the long run, the continuous presence of moisture leads to corrosion, especially in metal pipes. The formation of corrosion weakens the pipe structure, affecting the service life and reliability of the pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a municipal engineering pipeline leak sealing device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts a municipal engineering pipeline leak-sealing device, comprising an upper clamp and a lower clamp. A fixing plate is provided on both the upper and lower clamps. A pipeline is secured between the upper and lower clamps. The upper and lower clamps are fixed by bolts passing through the fixing plate. A partition is provided on the inner circumference of both the upper and lower clamps. A gasket is provided on the side of the partition away from the upper or lower clamp. A leakage hole is provided through the gasket, which directly contacts the pipeline. A filling cavity is formed between the upper or lower clamp and the gasket. Multiple through holes are provided on the partition. Multiple injection ports are provided on the outer circumference of both the upper and lower clamps, and the inside of the injection ports directly communicates with the filling cavity.

[0006] Preferably, a second thermoplastic tube is provided on both sides of the liner, and a first thermoplastic tube is provided above the second thermoplastic tube, with the first and second thermoplastic tubes enclosing both sides of the partition.

[0007] Preferably, a copper strip is provided at one end of the first thermoplastic tube and the second thermoplastic tube near the partition.

[0008] Preferably, a rubber plug is inserted and removed above the injection port.

[0009] Preferably, the partition is made of aluminum alloy.

[0010] Preferably, the gasket is made of rubber.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this design, the gasket directly contacts the pipe. A filling cavity is provided between the upper or lower clamping sleeve and the gasket, allowing for adjustment of areas where the pipe cannot be properly secured. Epoxy resin repair agent is filled into the injection port, flowing into the filling cavity and filling leaks or areas where the pipe cannot be properly secured. This design effectively prevents water seepage from the pipe and better secures it, significantly reducing water seepage and strengthening the seal at the source. This further prevents moisture accumulation. The gasket reduces the direct contact area, increases friction, and provides cushioning during pressurization. The partition ensures sufficient space for the filler, and the through-holes allow for circumferential filling, enhancing the leak-stopping effect. By isolating moisture, preventing further corrosion, and providing a stronger seal, pipe repair devices can extend the service life of pipelines and reduce the need for frequent maintenance or replacement due to corrosion or leakage. In the long run, this design helps reduce pipeline maintenance costs and improve overall pipeline safety. In addition, the sealing performance is further enhanced by the first and second thermoplastic pipes, preventing the filler from leaking out and strengthening the tightening effect on the pipeline, reducing water seepage, and making the leak-stopping effect more comprehensive. This municipal engineering pipeline leak-stopping device, through the design of gaskets, baffles, filling cavities, and injection ports, not only effectively improves the leak-stopping efficiency but also effectively reduces the problem of moisture accumulation leading to accelerated corrosion in traditional designs. It can provide a more reliable sealing effect and effectively extend the service life of pipelines. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-3As shown, the specific design of the above key components is described below: A municipal engineering pipeline leak sealing device includes an upper clamping sleeve 1 and a lower clamping sleeve 2. Both the upper clamping sleeve 1 and the lower clamping sleeve 2 are provided with a fixing plate 3. A pipeline is clamped between the upper clamping sleeve 1 and the lower clamping sleeve 2. The upper clamping sleeve 1 and the lower clamping sleeve 2 are fixed by bolts 4 passing through the fixing plate 3. Both the upper clamping sleeve 1 and the lower clamping sleeve 2 are provided with a partition plate 9 on their inner periphery. A gasket 10 is provided on the side of the partition plate 9 away from the upper clamping sleeve 1 or the lower clamping sleeve 2. A leakage hole 14 is opened through the gasket 10. The gasket 10 is in direct contact with the pipeline. A filling cavity 12 is formed between the upper clamping sleeve 1 or the lower clamping sleeve 2 and the gasket 10. Multiple through holes 11 are opened on the partition plate 9. Multiple injection ports 7 are provided on the outer periphery of both the upper clamping sleeve 1 and the lower clamping sleeve 2, and the inside of the injection ports 7 is directly connected to the filling cavity 12.The gasket 10 in the design directly contacts the pipe. By providing a buffer layer, it reduces the friction between the ferrule and the pipe, preventing excessive pressure concentration in a certain part of the pipe. This helps to transmit pressure more evenly and secure the pipe. A cavity 12 is provided between the upper ferrule 1 or lower ferrule 2 and the gasket 10. The cavity 12, formed by the gap, provides a space for filler, such as epoxy resin repair agent, to flow into the cavity 12 and fill the leaking or non-secured areas by filling the injection port 7 with epoxy resin repair agent. The filling cavity 12, designed to fit different pipe shapes, allows the filler to adapt to and fill any gaps in the pipe, enhancing the seal and ensuring a secure fixation. Multiple injection ports 7 allow epoxy resin repair agent or other fillers to flow into the filling cavity 12 and then be injected through the through-holes 11 on the partition 9 to the periphery of the gasket 10. In the event of gasket 10 damage, the filler can quickly fill and repair the damage, not only strengthening the gasket 10 but also further securing the pipe through the leak holes 14. Further sealing is performed at the water level to fill leaks or areas where the pipe cannot be properly secured, ensuring a good sealing effect. This design allows the repair agent to flow effectively throughout the entire filling cavity 12, filling the leak points and improving the repair effect. The baffle 9 separates the space of the filling cavity 12, ensuring that the filler can be evenly distributed within the cavity 12. At the same time, the through holes 11 allow the filler to flow smoothly to the periphery of the filling cavity 12, further enhancing the sealing effect and filling uniformity. By setting the first thermoplastic pipe 5 and the second thermoplastic pipe 6, the sealing performance is enhanced, preventing filler leakage and improving the overall sealing and pipe performance. The design of the filling cavity 12 and the injection port 7 further reduces the risk of water seepage and leakage. Through the design of the filling cavity 12 and the injection port 7, the filler can quickly and evenly flow to the leaking location or areas where it cannot be clamped, effectively improving the sealing efficiency and preventing further deterioration of the leakage problem. The design of the gasket 10 reduces the direct contact area, increases friction, further prevents moisture accumulation around the pipe, and extends the pipe's service life. The gasket 10 provides a buffering effect when tightening the pipe, preventing excessive pressure concentration and ensuring more even pressure application. Its design improves the stability of the pipe and reduces damage caused by excessive pressure. The combined design of the upper clamping sleeve 1, lower clamping sleeve 2, gasket 10, and thermoplastic tube further strengthens the tightening and sealing effect of the pipe, preventing filler leakage and ensuring a more comprehensive and reliable repair effect. Because the filler can be evenly distributed through the filling cavity 12 and fill various leaking or un-clamped locations, this design effectively prevents corrosion problems caused by moisture accumulation in traditional sealing methods, further improving the sealing effect.In summary, this design, through the effective combination of gasket 10, filling cavity 12, injection port 7, baffle 9 and thermoplastic pipe, solves a variety of problems encountered in the process of pipe sealing, improves sealing efficiency, sealing performance and long-term stability of the pipeline, significantly reduces maintenance costs and extends the service life of the pipeline.

[0021] A second thermoplastic tube 6 is provided on both sides of the gasket 10, and a first thermoplastic tube 5 is provided above the second thermoplastic tube 6. The first thermoplastic tube 5 and the second thermoplastic tube 6 are made of plastic with the characteristics of softening when heated and hardening when cooled. By heating, the sealing effect of the pipe is enhanced, thus playing a fixing role. The first thermoplastic tube 5 and the second thermoplastic tube 6 enclose both sides of the partition 9. A copper strip 13 is provided at one end of the first thermoplastic tube 5 and the second thermoplastic tube 6 near the partition 9. The design of the copper strip 13 forms a dividing line on the thermoplastic tube. The copper strip 13 has strong corrosion resistance and high temperature resistance. To prevent the thermoplastic tube from melting completely due to high temperatures, which would affect the sealing of the filling cavity 12, the copper strip 13 also serves to protect and support the filling cavity 12. A rubber plug 8 is inserted and removed above the injection port 7, which serves to prevent dust and protect the inside of the injection port 7. The baffle 9 is made of aluminum alloy, which has extremely high corrosion resistance and prevents long-term filling of filler from being viewed from above. The gasket 10 is made of rubber, which protects the pipe from damage caused by instantaneous pressure and also increases friction.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
