Description

Technical Field

[0001] The present invention relates to the technical field of gas pipeline cleaning, and in particular to a gas pipeline cleaning device. Background Art

[0002] After the gas pipeline is produced, there will be dirt inside it, so the pipeline needs to be cleaned. Traditionally, a brush is used for cleaning, but brush cleaning is troublesome. Therefore, cleaners are used on the market to clean the inner wall. Although cleaners are quick to clean, due to the long length of the gas pipeline, it is impossible to clean deep in the pipeline.

[0003] A search revealed that patent publication number CN217990296U discloses a pipe cleaning device for gas pipeline construction, comprising a connecting rod and an extension rod, wherein the left end of the connecting rod is fixedly connected to a cleaning ball, the left side of the cleaning ball is fixedly connected to a connecting block, the other end of the connecting block is fixedly connected to a cleaning ball, the outer side of the cleaning ball is fixedly connected to a uniformly distributed cleaning brush, and the outer side of the rubber sleeve is fixedly connected to a cleaning sponge sleeve. This patent, through the provision of the connecting rod, cleaning ball, cleaning ball, connecting block, rubber sleeve, cleaning cloth sleeve, cleaning sponge sleeve and cleaning brush, can conveniently clean the inner wall of the gas pipeline. By providing the extension rod, threaded rod and threaded groove, the connecting rod can be lengthened when the cleaning rod is not long enough, thereby facilitating the cleaning of the inner wall of the gas pipe.

[0004] However, the above patent still has some shortcomings: there are some impurities in the gas pipeline adhering to the inner wall of the pipeline, and only some dust can be removed by using a cleaning ball. Moreover, the operator cannot observe the inside of the pipeline, nor does he know where the impurities are located. The impurities adhering to the pipe wall cannot be effectively cleaned, and the length of a section of the gas pipeline is between 6 and 12 meters. If a complete cleaning is required, a longer extension rod is required, which undoubtedly increases the cost of use and the difficulty of operation. Summary of the Invention

[0016] Beneficial effects of the present invention:

[0017] (1) The present invention achieves a cleaning effect by providing a roller brush. During use, the air inlet pipe is first connected to an external air pump, and the air pump is started to deliver airflow into the pipe. The air pressure is used to push the piston plate to move, driving the roller brush to move along the pipe and clean impurities. The crushing rod at the front end of the roller brush cooperates with the scraper ring to crush and scrape off the adhered impurities. If larger impurities are encountered, the movement of the scraper ring will be hindered. At this time, the driving device can be used to drive the rotating shaft to rotate, and the rotation of the crushing rod and the scraper ring can be used to crush and scrape off the impurities. The piston plate can continue to move, and the entire interior of the pipe can be completely cleaned. The operation is simple and suitable for gas pipelines of various lengths.

[0018] (2) The present invention provides a plurality of force blocks on the rotating shaft. When the scraper ring is blocked by impurities and stops moving, the air pressure between the piston plate and the cover plate continues to increase, and the excess air is continuously discharged through the pressure relief pipe and blows the force blocks, causing the rotating shaft to rotate. As a result, the large impurities are crushed and scraped away by the rotation of the crushing rod and the scraper ring, and the impurities are completely removed. Then the crushing rod and the scraper ring can continue to move;

[0019] (3) The present invention provides a winding drum and a first pull rope. When the gas pipeline is cleaned, the winding drum is used to reel in the rope, so that the piston plate and the roller brush can be reset, which is convenient for the next cleaning work.

The air inlet pipe 11 is connected to the external air pump; when in use, the piston plate 14, the roller brush 16 and the scraper ring 17 are placed in the gas pipeline, and the cover plate 10 is covered to make the cover plate 10 and the piston plate 14 in a sealed state, and then the external air pump and the air inlet pipe 11 are used to inflate the interior. As the air pressure pushes, the piston plate 14 gradually moves toward the other end of the gas pipeline. During the movement, the scraper ring 17 scrapes off the impurities and the roller brush 16 sweeps the dust. When encountering larger impurities, the scraper ring 17 is blocked and cannot move. At this time, the driving device can drive the rotating shaft 15 to rotate, and the large impurities are crushed and scraped off by the rotation of the crushing rod 18 and the scraper ring 17. The piston plate 14 can continue to move, and the interior of the entire pipeline can be completely cleaned; the role of the sleeve 12 and the movable rod 13 is to support the piston plate 14. When the piston plate 14 moves, the movable rod 13 automatically disengages from the sleeve 12.

[0031] See Figure 1 A slide groove 4 is provided on the base 1, a slider is slidably connected in the slide groove 4, the slider is fixedly connected to the sliding seat 5, and the sliding seat 5 is connected to an external driving source; an external driving source is used to drive the sliding seat 5 to move in the slide groove 4, so that the piston plate 14, the roller brush 16 and the scraper ring 17 automatically enter the gas pipeline, and the external driving source can be a cylinder.

[0032] See Figures 3 to 5The driving device includes a plurality of force blocks 24, which are distributed in a circular array on the rotating shaft 15. A plurality of first mounting holes 21 are opened on the mounting plate 20, and each first mounting hole 21 is connected to an L-shaped pressure relief pipe 22, and a pressure relief valve is installed on the pressure relief pipe 22. A plurality of second mounting holes 23 are opened on the piston plate 14, and the plurality of first mounting holes 21 correspond to the plurality of second mounting holes 23 one by one, and the plurality of pressure relief pipes 22 are respectively inserted into the plurality of second mounting holes 23; when the scraper ring 17 is blocked by larger impurities, the piston plate 14 cannot move, and the air pressure between the piston plate 14 and the cover plate 10 increases and is discharged through the pressure relief pipe 22, and the air blows to the force blocks 24, thereby driving the rotating shaft 15 to rotate. The rotating shaft 15 drives the roller brush 16, the crushing rod 18 and the scraper ring 17 to rotate, crushing and removing the larger impurities, and then the piston plate 14 can continue to move, and the air cannot be discharged through the pressure relief pipe 22.

[0033] See Figure 1 and Figure 3 A mounting bracket 6 is provided on the sliding seat 5, and a winding drum 7 is rotatably mounted on the mounting bracket 6. A first pull rope 8 is wound on the winding drum 7. A through hole is opened on the cover plate 10, and a sealing ring 19 is provided in the through hole. One end of the first pull rope 8 passes through the sealing ring 19 and is connected to the mounting plate 20. The winding drum 7 is driven by an external motor; when the cleaning is completed, the winding drum 7 is wound, and the mounting plate 20 and the piston plate 14 are reset to facilitate subsequent cleaning work.

[0034] See Figure 5 and Figure 6 A groove 25 is provided on the side wall of the piston plate 14 near the mounting plate 20, and a magnetic part 26 is fixed in the groove 25. An adsorption part 27 is installed on the side wall of the mounting plate 20 near the piston plate 14, and a second pull rope 28 is connected between the mounting plate 20 and the groove 25; the piston plate 14 and the mounting plate 20 are connected by the magnetic part 26 and the adsorption part 27, and the diameter of the pressure relief pipe 22 is smaller than the diameter of the second mounting hole 23. When the winding drum 7 is reeled in and reset, under the action of the first pull rope 8, the mounting plate 20 is separated from the piston plate 14. At this time, the air inside the gas pipeline can be discharged through the second mounting hole 23, which is not only beneficial to the reset of the piston plate 14, but also the air discharged through the second mounting hole 23 can also clean the roller brush 16. It is worth noting that the magnetic part 26 is a magnet and the adsorption part 27 is made of iron material.

[0035] See Figure 1 and Figure 6 A plurality of support rods 2 are provided on the base 1, a support seat 3 is fixed on the support rod 2, and a plurality of blocks 29 are provided on the support seat 3 away from the cover plate 10; the plurality of support seats 3 are used to place the gas pipeline, and the block 29 prevents the piston plate 14 from being separated from the gas pipeline.

[0036] The working principle of the present invention is as follows: first, the gas pipeline to be cleaned is placed on multiple support seats 3, and an external driving source (not shown) is used to drive the sliding seat 5 to move. The piston plate 14, the roller brush 16 and the scraper ring 17 enter the gas pipeline. The cover plate 10 blocks one end of the gas pipeline. An external air pump (not shown) and the air inlet pipe 11 are used to inflate the interior of the pipeline. As the air pressure pushes, the piston plate 14 gradually moves toward the other end of the gas pipeline. At this time, due to the continuous increase in the space between the cover plate 10 and the piston plate 14, the air will not be discharged through the pressure relief pipe 22. During the movement, the scraper ring 17 scrapes off impurities and the roller brush 16 cleans the dust.

[0037] When encountering larger impurities, the scraper ring 17 is blocked and cannot move, and the piston plate 14 cannot move. The air pressure between the cover plate 10 and the piston plate 14 increases and is discharged through the pressure relief pipe 22. The air blows to the force block 24, thereby driving the rotating shaft 15 to rotate. The rotating shaft 15 drives the roller brush 16, the crushing rod 18 and the scraper ring 17 to rotate, crushing and removing the larger impurities. After the impurities no longer hinder the movement, the piston plate 14 can continue to move, and the interior of the entire pipeline can be completely cleaned.

[0038] When the piston plate 14 moves, it will pull the first pull rope 8 to move, and the winding drum 7 will pay out the line. After the piston plate 14 moves to the other end of the gas pipeline, the cleaning is completed. At this time, an external motor (not shown) is used to drive the winding drum 7 to rotate to reel in the line. Due to the high air pressure in the gas pipeline, the piston plate 14 cannot move smoothly. The first pull rope 8 will pull the mounting plate 20 away from the piston plate 14. At this time, the air inside the gas pipeline can be discharged through the second mounting hole 23 to relieve the pressure inside the pipeline. The discharged air can blow away the impurities on the roller brush 16. After the reeling is completed, the piston plate 14 can be reset, and then the sliding seat 5 is reset, and the cleaned pipeline can be removed.

[0039] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
