Description

Technical Field

[0001] This utility model relates to the field of municipal engineering pipeline maintenance technology, specifically an auxiliary device for repairing leaks in urban pipelines. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] When existing urban pipelines encounter leaks, water needs to be shut off for repair or the pipelines need to be replaced. When encountering pipelines where water cannot be shut off, it is necessary to coordinate with the surrounding municipal water environment for a long time before shutting off the water for repair. During this period, the pipeline continues to leak, which will cause a lot of water waste. Therefore, an auxiliary device for urban pipeline leak repair is proposed to solve the above-mentioned problems. Utility Model Content

[0034] The top of the fixing clip 2 is provided with a storage groove that is compatible with the sealing box 401, and an anti-slip pad 8 is provided between the positioning clip 1 and the pipe 6.

[0035] The anti-slip pad 8 has anti-slip capabilities and can prevent the positioning clip 1 from shifting during installation;

[0036] The extrusion mechanism 3 includes a rotating disk 301, which is rotatably connected to the inside of the fixed clamp 2. A screw tube 302 is fixedly connected to the inner side of the rotating disk 301. An internal hexagonal nut 303 is fixedly connected to the bottom of the screw tube 302. A screw rod 304 is threadedly connected to the inside of the screw tube 302. A connecting block 305, which is fixedly connected to the bottom of the sealing box 401, is fixedly connected to the top of the screw rod 304.

[0037] The extrusion mechanism 3 can compress the sealing film 5 to maintain a tight fit with the outside of the pipe 6;

[0038] The sealing box 401 is arc-shaped and matches the outer diameter curvature of the pipe 6. The left and right sides of the sealing box 401 are slidably connected to the left and right side walls of the inner cavity of the storage groove.

[0039] The sliding connection between the sealing box 401 and the left and right sides of the storage slot can prevent the sealing box 401 from rotating when it is raised or lowered.

[0040] The injection hole 403 is used to inject expanded foam. The injection hole 403 is connected to the filling groove 402. The filling groove 402 is used for the expanded foam to expand and adhere to the bottom of the sealing film 5.

[0041] The expanding foam can expand from liquid to solid after injection, forming support for the bottom of the sealing film 5.

[0042] Working principle:

[0043] Step 1: During the process of coordinating the municipal water environment for the water leakage of pipe 6, fasten the positioning clip 1 to the back of the water leakage point of pipe 6, place the anti-slip pad 8 between the positioning clip 1 and pipe 6, and fix the fixing clip 2 to the front of the water leakage point of pipe 6 with bolts 7.

[0044] Step 2: Apply the sealing film 5 to the leaking part of the pipe 6. Turn the internal hex nut 303 with an internal hex wrench. The internal hex nut 303 drives the screw tube 302 to rotate. When the screw tube 302 rotates, it pushes the screw rod 304 through thread transmission. Through the sliding connection between the sealing box 401 and the storage groove, the screw rod 304 pushes the sealing box 401 closer to the pipe 6. The sealing film 5 is fixed by the tooth groove of the sealing box 401.

[0045] Step 3: Use a glue gun to inject expanding foam into the filling groove 402 through the glue injection hole 403. After the expanding foam is injected into the filling groove 402, it will naturally foam and squeeze the sealing film 5 to fill the uneven areas on the outside of the pipe 6, improve the sealing effect, temporarily stop the leak, and assist in the repair of the pipe 6.
