Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a rigid pipeline anti-leakage structure. Background Technology

[0002] Pipelines are critical infrastructure used in industrial, building, and municipal systems to transport fluids (liquids, gases, or slurries). Their design, material selection, and maintenance directly affect the safety and efficiency of the system. Rigid pipes are tubular structures with high mechanical strength, are not easily deformed, and can maintain a fixed shape.

[0003] In the sandy geological conditions of the Yellow River floodplain, flange connections are often used at rigid pipe joints. However, the internal gaskets are easily corroded by underground moisture, leading to pipe leaks. Utility Model Content

[0004] The purpose of this utility model is to provide a rigid pipe anti-leakage structure that can overcome the shortcomings of the sealing gasket at the flange connection of rigid pipes being easily damaged.

[0005] To achieve the above objectives, a rigid pipe anti-leakage structure is provided, including a pipe one and a pipe two. The pipe one is located on the right side of the pipe two. An annular block one is fixedly connected to the left end of the pipe one. An annular groove one is opened on the right side of the pipe two.

[0006] A square block is rotatably connected to the outer side of pipe one, and a square block is fixedly connected to the outer side of pipe two. An annular block is fixedly connected to the left side of square block one, and an annular groove is formed on the right side of square block two. A circular block is disposed inside the annular groove, and a sealing block is movably connected to the right side of the circular block. The sealing block is made of expanding rubber material. This facilitates increased sealing between the pipes.

[0007] According to the rigid pipe anti-leakage structure described above, the second annular block is disposed inside the second annular groove and is threadedly connected to the second square block. This facilitates the sliding of the second annular block.

[0008] According to the rigid pipe anti-leakage structure, a circular hole is provided on the left side inside the second annular groove. Two circular holes are provided and symmetrically distributed. A sliding rod is installed inside each of the two circular holes. An arc-shaped block is fixedly connected to the left end of each sliding rod. A threaded rod is rotatably connected to the left side of the second square block. This facilitates the installation and disassembly of the sealing block.

[0009] According to the rigid pipe anti-leakage structure described above, the sliding rod and the square block are slidably connected, the sliding rod and the circular block are fixedly connected, and the circular block and the square block are slidably connected. This facilitates the sliding of the sliding rod, which in turn causes the circular block to slide.

[0010] According to the aforementioned rigid pipe anti-leakage structure, the left end of the threaded rod passes through the arc-shaped block and is fixedly connected to a control block, and the threaded rod and the arc-shaped block are threadedly connected. This facilitates the rotation of the threaded rod.

[0011] According to the rigid pipe anti-leakage structure described above, the annular block one is disposed inside the annular groove one and is slidably connected to the pipe two. This facilitates the rotation of the annular block one.

[0012] The present invention has the following advantages: Compared with the prior art, the arrangement of the ring block 1, square block 1, square block 2, ring block 2, circular block, sealing block, sliding rod, arc block, and threaded rod, and the sealing block being made of expanding rubber material, facilitates the increase of the sealing between pipes, protects the pipes from leakage, and also makes it easier for users to replace damaged sealing blocks.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4This utility model provides a rigid pipe anti-leakage structure, which includes a pipe 1 and a pipe 2. The pipe 1 is located on the right side of the pipe 2. An annular block 3 is fixedly connected to the left end of the pipe 1. An annular groove 4 is opened on the right side of the pipe 2. A square block 5 is rotatably connected to the outside of the pipe 1. A square block 6 is fixedly connected to the outside of the pipe 2. An annular block 7 is fixedly connected to the left side of the square block 5. An annular groove 8 is opened on the right side of the square block 6. A circular block 9 is provided inside the annular groove 8. A sealing block 10 is movably connected to the right side of the circular block 9. The sealing block 10 is made of expanding rubber material. The annular block 7 is located inside the annular groove 8 and is threadedly connected to the square block 6. The annular block 3 is located inside the annular groove 4 and is slidably connected to the pipe 2.

[0022] Two circular holes 11 are provided on the left side of the inner side of the annular groove 2 8. The two circular holes 11 are symmetrically distributed. A sliding rod 12 is provided inside each of the two circular holes 11. An arc-shaped block 13 is fixedly connected to the left end of the sliding rod 12. A threaded rod 14 is rotatably connected to the left side of the square block 2 6. The sliding rod 12 and the square block 2 6 are slidably connected. The sliding rod 12 is fixedly connected to the annular block 9. The annular block 9 and the square block 2 6 are slidably connected. The left end of the threaded rod 14 passes through the arc-shaped block 13 and is fixedly connected to the control block 15. The threaded rod 14 and the arc-shaped block 13 are threadedly connected.

[0023] After the sealing block 10 absorbs water and expands over time, it needs to be replaced. At this time, the operator holds the control block 15 and rotates the threaded rod 14. The rotation of the threaded rod 14 causes the arc block 13 to move. The movement of the arc block 13 moves the slide rod 12, and the movement of the slide rod 12 moves the annular block 9 in the annular groove 8. The annular block 9 moves the sealing block 10 out of the annular groove 8. In this way, a new sealing block 10 is replaced. The arrangement of annular block 13, square block 15, square block 26, annular block 27, annular block 9, sealing block 10, slide rod 12, arc block 13, and threaded rod 14 is such that the sealing block 10 is made of expanding rubber material to increase the sealing between pipes, protect the pipes from leakage, and also make it easy for users to replace the damaged sealing block 10.

[0024] Working principle: When the worker is connecting the pipes, he will slide the annular block 3 of pipe 1 into the annular groove 4. Then, the worker will hold the square block 5 and rotate it. The rotation of the square block 5 will rotate the annular block 7 into the annular groove 8. If there is moisture inside, the sealing block 10 is made of expanding rubber material. Once the expanding rubber material absorbs water and expands, it will fill the gaps inside, increase the sealing between the pipes, and prevent water leakage.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
