Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning equipment technology, and in particular to a novel straight-plate pipeline cleaning equipment. Background Technology

[0002] During the long-term transportation of oil and gas, impurities inevitably accumulate on the inner wall of the pipeline. Over time, this accumulation can affect the pipeline's transport area and reduce its transport efficiency. Therefore, to ensure the normal and efficient use of the pipeline, impurities are usually cleaned from the pipeline regularly using a pipeline cleaning machine.

[0003] For example, Chinese utility model patent (CN212916896U) discloses a straight-plate pig for acidic gas fields, including a support cylinder, scrapers, partitions, support plates, traction plates, anti-collision ends, and anti-loosening bolts. The entire pig is symmetrically arranged about the middle of the support cylinder. Steps are provided on the support cylinder near both ends. At least two scrapers are fitted on the outside of the steps, and the outer diameter and thickness of each scraper are different. Partitions are provided between the scrapers. Support plates, traction plates, and anti-collision ends are arranged in sequence on the outside of the scrapers. At least two partitions are provided between the scrapers and the support plates. Anti-loosening bolts lock the anti-collision ends, traction plates, support plates, partitions, and scrapers on the steps. The support plates, scrapers, traction plates, partitions, and anti-collision ends are all round plates made of acid-resistant polyurethane material.

[0004] When using the above technology, the following technical problems were found in the existing technology: the above-mentioned pig simply relies on the scraper to clean some of the free deposits, and the cleaning effect is poor. At the same time, when the blockage in the pipe wall is stubborn, the wear on the scraper is also large. Therefore, we designed a new type of straight plate pig to provide another technical solution to the above technical problems. Utility Model Content

Through the design of the adjustment mechanism, the blunt blade can adapt to pipe bends or diameter changes, while ensuring that the blunt blade maintains appropriate contact with the pipe wall during the pig's movement. The design of the fixing component makes the replacement of the blunt blade more convenient and quick. The guide component guides the pig along the central axis of the pipe, preventing the pig from deviating or swaying within the pipe. This helps ensure that the pig can thoroughly and evenly clean debris from the inner wall of the pipe.

[0039] The inner sides of both sides of the second fixed plate 15 are provided with limiting grooves 20. The first sliding rod 16 is slidably connected to the second fixed plate 15 through the limiting grooves 20. The limiting grooves 20 restrict the movement of the first sliding rod 16.

[0040] Example 2

[0041] Reference Figures 6-9 The fixing assembly includes a first locking rod 21, a rotating plate 22, a screw 23, and a second locking rod 24. The first locking rod 21 is fixed to both ends of the bottom of the blunt blade 10. The first locking rod 21 is slidably connected to the first connecting plate 12. The rotating plate 22 is rotatably connected to both ends of the inner top side of the first connecting plate 12. A screw 23 is fixed to one end of the rotating plate 22. The screw 23 is located inside the first connecting plate 12. The second locking rod 24 is threaded on the outer side of the screw 23. The second locking rod 24 is slidably connected to the first connecting plate 12 and is locked to the first locking rod 21. The design of the fixing assembly makes the replacement of the blunt blade 10 more convenient and quick.

[0042] The guide assembly includes a third fixed plate 25, a sliding plate 26, a guide wheel 27, and a second spring 28. Multiple third fixed plates 25 are evenly distributed and fixed on the outer side of the second connecting rod 7. The sliding plate 26 is slidably connected to the inner side of the third fixed plate 25. The guide wheel 27 is fixed on the top of the sliding plate 26, and the second spring 28 is fixed on the bottom of the sliding plate 26. The second spring 28 is located inside the third fixed plate 25.

[0043] The guiding component directs the pig along the central axis of the pipeline, preventing it from deviating or swaying within the pipeline. This helps ensure that the pig can thoroughly and evenly remove debris from the pipeline walls.

[0044] The novel straight-plate pipe cleaning tool provided by this utility model is used as follows: When the cleaning tool is inserted into the pipe, the blunt blade 10 and the guide wheel 27 simultaneously contact the inner wall of the pipe. Since the blunt blade 10 is fixed to the first connecting plate 12 by a snap-fit ​​mechanism, and since the first connecting plate 12 is rotatably connected to the fixing frame 11, the inner wall of the pipe squeezes the blunt blade 10. The movement of the blunt blade 10 drives the first connecting plate 12 to rotate. Since the first connecting plate 12 is fixedly connected to the fixing rod 13 and the fixing rod 13 is rotatably connected to the third connecting rod 14, the rotation of the first connecting plate 12 drives the third connecting rod 14 to rotate, thus causing the third connecting rod 14 to rotate. As the first sliding rod 16 moves, and because the first sliding rod 16 is slidably connected to the second fixed plate 15 through the limiting groove 20, the first sliding rod 16 moves to one end. As the first sliding rod 16 is fixedly connected to the second connecting plate 17, the movement of the first sliding rod 16 drives the second connecting plate 17 to move, thereby causing the second sliding rod 18, which is fixedly connected to the second connecting plate 17, to move. As the outer side of the second sliding rod 18 is sleeved with the first spring 19, the first spring 19 is compressed by the second connecting plate 17, thereby allowing the blunt blade 10 to smoothly enter the inside of the pipe. The blunt blade 10 can also be adjusted at the bends in the pipe.

[0045] When the inner wall of the pipe squeezes the guide wheel 27, the guide wheel 27 is fixedly connected to the sliding plate 26, so the movement of the guide wheel 27 drives the sliding plate 26 to move. Since the sliding plate 26 is slidably connected to the third fixed plate 25, and the bottom of the sliding plate 26 is fixed with a second spring 28 located inside the third fixed plate 25, the guide wheel 27 is tightly in contact with the inner wall of the pipe under the elastic support of the second spring 28.

[0046] By adjusting the design of the blunt blade 10, it can adapt to the bending or diameter change of the pipe and maintain appropriate contact with the pipe wall, so that the blunt blade 10 can crush the stubborn blockages on the inner wall of the pipe.

[0047] When the blunt blade 10 wears out after prolonged use, an Allen wrench can be inserted into the inside of the rotating plate 22 to rotate it. Since the rotating plate 22 is fixedly connected to the screw 23, the rotation of the rotating plate 22 drives the screw 23 to rotate. Since the screw 23 is threadedly connected to the second locking roller 24, the rotation of the screw 23 drives the second locking roller 24 to move, so that the second locking roller 24 is no longer locked to the first locking roller 21, allowing the first locking roller 21 to be replaced. The design of the fixing component makes the replacement of the blunt blade 10 more convenient and quick.
