Description

Technical Field

[0001] This utility model relates to the field of coal mine machinery engineering technology, and in particular to a pipeline connection structure for a gas pump. Background Technology

[0002] Gas pump pipelines are key transport components in coal mine gas extraction systems. They are mainly used to transport gas escaping from underground coal seams from the mining face to surface treatment or storage equipment. They are an important channel for ensuring gas concentration control in mines and preventing gas explosion accidents. They must have good sealing performance, negative pressure resistance, and wear resistance. The gas pump pipeline connection structure is the core component connecting the gas pump to each section of the transport pipeline. Its function is to achieve a stable connection between the gas pump and the pipeline, and between pipelines, to ensure that there is no leakage of gas during the transport process. At the same time, it must be adapted to the operating conditions of the gas pump to provide structural support for the efficient and safe transport of gas.

[0003] The commonly used gas pump pipeline connection structures in the current coal mining field mainly include flange connection structure, quick-connect snap-fit ​​connection structure and threaded connection structure. However, the existing structures lack an effective active cleaning mechanism during use. Long-term accumulation of impurities will not only lead to a significant decrease in gas transportation efficiency, but also shorten the service life of gas pumps and pipelines. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a pipeline connection structure for a gas pump, aiming to improve the problem that long-term accumulation of impurities not only leads to a significant decrease in gas transportation efficiency but also shortens the service life of the gas pump and pipeline.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline connection structure for a gas pump, comprising a base, a limiting post slidably connected to the outer wall of the base, a support frame fixedly connected to the outer wall of the limiting post, a motor fixedly connected to the outer wall of the support frame, a rotating post fixedly mounted at the output end of the motor, and an eccentric wheel fixedly connected to the outer wall of the rotating post. A second limiting post slidably connected inside the support frame, a spring fixedly connected to the lower surface of the support frame, a pipeline 1 attached to the upper surface of the base, a gas pump body fixedly connected to the outer wall of the pipeline 1, a second pipeline attached to the inner wall of the pipeline 1, and a filter assembly provided on the inner wall of the second pipeline for filtering particulate impurities.

[0006] The above technical solution involves starting a motor to drive rotating column one to rotate, rotating column one to drive eccentric wheel to rotate, eccentric wheel to drive limiting column two to move, limiting column two to drive spring one to move, spring one to drive limiting column one to move, limiting column one to drive pipeline one to move, and pipeline one to drive the gas pump body to move, ensuring that pipeline two moves synchronously with pipeline one. This not only avoids the accumulation of impurities and blockage of pipelines, improving gas transportation efficiency, but also extends the service life of the gas pump and pipeline.

[0007] Preferably, the filter assembly includes a sieve plate, a rotating column two is rotatably connected inside the sieve plate, a limiting plate one is fixedly connected to the outer wall of the rotating column two, and a ring is fixedly connected to the outer wall of the limiting plate one.

[0010] Preferably, the outer wall of the ring is rotatably connected to the inner wall of the second pipe, and the outer wall of the first limiting plate is rotatably connected to the outer wall of the screen plate.

[0012] Preferably, the outer wall of the second spring is fixedly connected to the inside of the first pipe, and the outer wall of the limiting piece is slidably connected to the inside of the first pipe.

[0013] Preferably, the outer wall of the second fixed column is slidably connected to the inside of the first pipe, and the outer wall of the limiting block is slidably connected to the inside of the second pipe.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the first limiting column drives the first pipe to move, and the first pipe drives the gas pump body to move, ensuring that the second pipe moves synchronously with the first pipe. This not only avoids the accumulation of impurities and blockage of the pipe, and improves the gas transportation efficiency, but also extends the service life of the gas pump and the pipe.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a gas pump pipe connection structure, including a base 1, a limiting post 2 slidably connected to the outer wall of the base 1, a support frame 3 fixedly connected to the outer wall of the limiting post 2, a motor 4 fixedly connected to the outer wall of the support frame 3, a rotating post 5 fixedly installed at the output end of the motor 4, and an eccentric wheel 6 fixedly connected to the outer wall of the rotating post 5. A limiting post 7 slidably connected inside the support frame 3, a spring 8 fixedly connected to the lower surface of the support frame 3, a pipe 9 attached to the upper surface of the base 1, a gas pump body 10 fixedly connected to the outer wall of the pipe 9, a pipe 11 attached to the inner wall of the pipe 9, and a filter assembly provided on the inner wall of the pipe 11 for filtering particulate impurities. Specifically, the motor 4 drives the rotating column 5 to rotate, which in turn drives the eccentric wheel 6 to rotate. The support frame 3 fixes the motor 4, ensuring its position does not change during operation. Simultaneously, the support frame 3 restricts the rotating column 5, preventing its position from shifting when driven by the motor 4. The rotating column 5 also restricts the eccentric wheel 6, ensuring that its rotation synchronously drives the eccentric wheel 6. This rotation of the eccentric wheel 6 causes the limiting column 7 to move, which in turn moves the spring 8, which in turn moves the limiting column 2. The support frame 3 restricts the limiting column 7, ensuring its position does not shift during movement, and also restricts the spring 8, ensuring its position does not change during movement. The base 1 restricts the position of the limiting post 2, preventing it from shifting during movement. This movement of the limiting post 2 synchronously moves the pipe 9, which in turn moves the gas pump body 10, and consequently, the pipe 11. The base 1 restricts the position of the pipe 9, ensuring it remains constant during movement. Simultaneously, the base 1 restricts the position of the gas pump body 10, ensuring it remains constant during movement. Furthermore, the pipe 9 restricts the pipe 11, causing it to move synchronously. This movement of the pipe 11 vibrates and filters particulate impurities within it, preventing impurities from accumulating and clogging the pipe, improving gas delivery efficiency, and extending the service life of the gas pump and pipes.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The filter assembly includes a sieve plate 12, a rotating column 13 is rotatably connected inside the sieve plate 12, a limiting plate 14 is fixedly connected to the outer wall of the rotating column 13, and a ring 15 is fixedly connected to the outer wall of the limiting plate 14. Specifically, the sieve plate 12 is fixed by the second pipe 11, so that the sieve plate 12 filters the particulate impurities inside the second pipe 11. The sieve plate 12 restricts the second rotating column 13, so that the position of the second rotating column 13 does not shift when it rotates. The second rotating column 13 fixes the first limiting plate 14, so that the second rotating column 13 drives the first limiting plate 14 to rotate synchronously. The second pipe 11 restricts the ring 15, so that the position of the ring 15 does not change when it rotates.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the rotating column 5 is rotatably connected to the inside of the support frame 3, and the outer wall of the spring 8 is fixedly connected to the upper surface of the base 1; the outer wall of the gas pump body 10 is in contact with the upper surface of the base 1, and the lower surface of the limiting column 7 is fixedly connected to the upper surface of the base 1; the outer wall of the ring 15 is rotatably connected to the inner wall of the pipe 11, and the outer wall of the limiting plate 14 is rotatably connected to the outer wall of the screen plate 12. Specifically, the support frame 3 restricts the rotating column 5 so that its position does not shift when driven to rotate by the motor 4; the base 1 fixes the spring 8 so that its position does not change when it moves; the base 1 restricts the gas pump body 10 so that it does not fall when it moves; the base 1 fixes the limiting column 7 so that its position does not change when it moves; the pipe 11 restricts the ring 15 so that its position does not change when it rotates; and the screen plate 12 restricts the limiting plate 14 so that the limiting plate 14 scrapes away the particulate impurities filtered on the surface of the screen plate 12.

[0022] Reference Figure 1 , Figure 3 and Figure 4 Pipe 19 has an internal threaded connection to a limiting post 3 16. The outer wall of the limiting post 3 16 is fixedly connected to a fixing post 17. The outer wall of the fixing post 17 is fixedly connected to a limiting block 18. The outer wall of the fixing post 17 is attached to a limiting plate 2 19. The outer wall of the limiting plate 2 19 is fixedly connected to a fixing post 20. The outer wall of the limiting plate 2 19 is fixedly connected to a spring 21. The outer wall of the fixing post 20 is fixedly connected to a limiting piece 22. Specifically, rotating the limiting post 3 16 outward causes the fixed post 1 17 to move, which in turn moves the limiting block 18. Pipe 1 9 restricts the limiting post 3 16, ensuring its position remains unchanged. Simultaneously, pipe 1 9 restricts the fixed post 1 17, ensuring its position does not shift during movement. Pipe 2 11 restricts the limiting block 18, preventing its position from shifting. This causes the limiting block 18 to move synchronously, moving the limiting plate 2 19. The movement of the limiting plate 2 19 moves the fixed post 2 20, which in turn moves the spring 2 21. Pipe 1 9 further restricts the limiting plate 2 19... The guide pipe allows the limiting plate 19 to move only inside the pipe 9. The pipe 9 also restricts the fixed post 20, ensuring its position does not shift during movement. Furthermore, the pipe 9 fixes the spring 21, preventing its position from changing during movement. This movement of the spring 21 drives the limiting plate 22, which in turn restricts its position, preventing it from shifting. This allows the limiting block 18 to disengage from the pipes 11 and 9, facilitating disassembly and enabling the cleaning and replacement of internal filters or components.

[0023] Reference Figure 1 , Figure 3 and Figure 4 The outer wall of spring 21 is fixedly connected to the inside of pipe 9, and the outer wall of limiting piece 22 is slidably connected to the inside of pipe 9; the outer wall of fixed column 20 is slidably connected to the inside of pipe 9, and the outer wall of limiting block 18 is slidably connected to the inside of pipe 11. Specifically, spring 21 is fixed by pipe 1 9 so that its position does not change when it moves; limiting plate 22 is restricted by pipe 1 9 so that its position does not shift when it moves; fixing post 20 is guided by pipe 1 9 so that its position does not change when it moves; and limiting block 18 is restricted by pipe 2 11 so that it does not fall off when it moves.

[0024] Working principle: When particulate impurities need to be filtered, the motor 4 drives the rotating column 5 to rotate, the rotating column 5 drives the eccentric wheel 6 to rotate, the eccentric wheel 6 drives the limiting column 7 to move, the limiting column 7 drives the spring 8 to move, the spring 8 drives the limiting column 2 to move, the limiting column 2 drives the pipe 9 to move, and the pipe 9 drives the gas pump body 10 to move, ensuring that the pipe 11 moves synchronously with the pipe 9. This not only avoids the accumulation of impurities and blockage of the pipe, improving the gas conveying efficiency, but also extends the service life of the gas pump and the pipe. When the pipes need to be disassembled for cleaning and replacement, the limiting post 3 16 is rotated outward to move the fixing post 1 17, the fixing post 1 17 moves the limiting block 18, the limiting block 18 moves the limiting plate 2 19, the limiting plate 2 19 moves the fixing post 2 20, the fixing post 2 20 moves the spring 2 21, the spring 2 21 moves the limiting piece 22, and the limiting block 18 disengages from the inside of the pipe 2 11 and the pipe 1 9, thus completing the disassembly. This achieves the effect of facilitating the disassembly of the pipe 1 9 and the pipe 2 11, and cleaning and replacing the internal filter or components. In other words, when the gas pump pipeline is in use, it not only achieves the effects of preventing impurities from accumulating and clogging the pipeline, improving the gas transportation efficiency, and extending the service life of the gas pump and pipeline, but also facilitates the disassembly of pipeline 19 and pipeline 21, and the cleaning and replacement of internal filters or components.
