[0002] Pipelines are usually used for water supply, drainage, heating, and long-distance transportation of oil and natural gas. When two or more pipelines are connected, flange connections are usually used, and sealing materials (such as rubber rings, etc.) are used between the two flanges to ensure sealing to prevent leakage. When the connected pipelines are in use, they are usually buried underground. The sealing gaskets or rubber rings used for sealing at the pipeline joints are easily affected by the humid environment and will age or corrode and lose their sealing properties, resulting in leakage. Summary of the invention

[0011] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0012] like Figure 1-Figure 4 As shown, a pipeline anti-seepage device comprises a pipeline 1 and a pipeline 2, wherein one end of the pipeline 1 is fixedly connected to a flange 3, and one end of the pipeline 2 is fixedly connected to a flange 2 4, and a rubber ring 5 is sandwiched between the flange 1 3 and the flange 2 4 to form a sealing mechanism, and clamping mechanisms are arranged around the sealing mechanism;

[0013] The clamping mechanism includes a gasket 6, which is a long strip made of elastic rubber. The gasket 6 contacts the peripheral wall of the sealing mechanism. A pressure block 7 with an inclined surface is provided on the side of the gasket 6 away from the sealing mechanism. A guide rod 8 passing through the gasket 6 and the pressure block 7 is provided on the flange 2 4. An L-shaped plate 9 is fixedly connected to the flange 1 3, and the free end of the horizontal section of the L-shaped plate 9 is close to the inclined surface of the pressure block 7.

[0014] The flange 1 3 , flange 2 4 and rubber ring 5 are all squares with the same side length. The right end of the gasket 6 is flush with the right side wall of the flange 2 4 , and the left end of the gasket 6 is located on the flange 1 3 on the left side of the rubber ring 5 and close to the vertical section of the L-shaped plate 9 .

[0015] The pressing block 7 is in the shape of a right-angled triangular prism. The lengths of the pressing block 7 and the gasket 6 are the same as the side lengths of the rubber ring 5. The vertical surface of the pressing block 7 is flush with the right end of the gasket 6. The horizontal surface of the pressing block 7 faces the peripheral walls of flange 2 4 and flange 1 3, and the left side of the horizontal surface of the pressing block 7 is flush with the left end of the gasket 6.

[0016] The L-shaped plate 9 consists of a horizontal section and a vertical section. The horizontal section of the L-shaped plate 9 is away from the flange 1 3 , and the left side wall of the vertical section of the L-shaped plate 9 is flush with the left side wall of the flange 1 3 .

[0017] The free end of the horizontal section of the L-shaped plate 9 is an inclined surface that matches the inclined surface of the pressing block 7 , that is, the inclined surface of the L-shaped plate 9 is parallel to the inclined surface of the pressing block 7 .

[0018] There are a number of guide rods 8 on each of the clamping mechanisms. One end of each guide rod 8 is vertically fixed to the peripheral wall of the second flange 4 , and the other end of the guide rod 8 is movable to penetrate the corresponding gasket 6 and the pressure block 7 .

[0019] The four corners of the side walls of the flange 1 3 and the flange 2 4 are provided with corresponding mounting holes 10 , each mounting hole 10 is inserted with a corresponding bolt 11 , and the other end of each bolt 11 is provided with a nut 12 .

[0020] A limit stop ring 13 is provided at the free end of each guide rod 8 to limit the pressure block 7 from falling off.

[0021] When in use, the nut 12 is turned, and the flange 13 and the flange 2 4 are moved relative to each other by tightening the bolts 11 and the nuts 12, so that the rubber ring 5 is clamped. At the same time, the L-shaped plate 9 moves synchronously with the flange 13, and the pressure block 7 is driven to move synchronously by the guide rod 8 that moves with the flange 2 4. When the inclined surface of the L-shaped plate 9 contacts the inclined surface of the pressure block 7, as the bolts 11 and the nuts 12 are tightened, the L-shaped plate 9 continues to move to the left. After the pressure block 7 is thrusted by the L-shaped plate 9, the pressure block 7 gradually approaches the flange 2 4 along the guide rod 8 through the guide rod 8 to press the gasket 6. When the bolts 11 and the nuts 12 are fully tightened, the pressure block 7 presses the gasket 6 to complete the secondary sealing of the pipeline.
