Description

Technical Field

[0001] This utility model relates to the field of gas pipeline maintenance technology, and in particular to a gas pipeline cleaning device. Background Technology

[0002] During long-term use, the inner wall of gas pipelines is prone to the formation of dirt due to the deposition of impurities in the gas and the corrosion of moisture, such as hard rust layers, oil stains, and dust accumulation. This dirt can not only reduce the inner diameter of the pipeline and increase the resistance to gas transmission, but may also cause gas valve blockage due to the shedding of impurities, and even cause safety hazards. Therefore, regular cleaning of the inner wall of gas pipelines is an important part of ensuring the safe and stable operation of the gas system. Currently, gas pipeline cleaning mainly relies on manual operation or traditional mechanical cleaning equipment, but there are many limitations in practical applications: the cleaning components of traditional cleaning devices, such as scrapers and brushes, are mostly of fixed size and cannot be adjusted according to the inner diameter of the pipeline. When dealing with gas pipelines of different specifications (such as DN50, DN100), it is necessary to change to cleaning tools of the corresponding size, which not only increases equipment costs but also prolongs operation time and reduces cleaning efficiency. The dirt on the inner wall of the pipeline usually includes two types: one is a hard rust layer or clumps of oil, which needs to be scraped off by hard parts such as scrapers; the other is loose dust or residual impurities, which need to be swept away by flexible parts such as brushes. Existing devices mostly adopt a single cleaning structure (such as only scrapers or only brushes), or although they have both, the layout is unreasonable and cannot work simultaneously and efficiently, resulting in hard dirt residue or floating dust not being cleaned properly, affecting the cleaning effect. Therefore, it is necessary to design a gas pipeline cleaning device to solve the above problems. Utility Model Content

The power supply box 37 is electrically connected to the drive motor 31, the second electric push rod 381 and the third electric push rod 391 respectively through wires.

[0023] In this embodiment, the mobile device 2 includes a fixed connecting plate 21. A first disc 22 is fixedly connected to both the left and right ends of the fixed connecting plate 21. A first groove 23 is opened around the left end of the first disc 22. A first electric push rod 24 is fixedly connected to each of the first grooves 23. The output end of the first electric push rod 24 passes through the first disc 22 and is fixedly connected to a connecting seat 25. A moving wheel 26 is provided in each of the connecting seats 25. The first grooves 23 are distributed in a ring at equal intervals on the first disc 22. The moving wheel 26 is rotatably connected to the connecting seat 25 through a wheel axle and the wheel surface protrudes from the outside of the connecting seat 25. The first disc 22 on the left side is fixedly connected to the right end of the traction rope 1 by welding. The first disc 22 on the right side is fixedly connected to the left end of the outer shell 4 by welding.

[0024] Through the above scheme: When the mobile device 2 is working, the first discs 22 at both ends of the fixed connecting plate 21 are fixed to the right end of the traction rope 1 and the left end of the outer shell 4 respectively by welding. The first electric push rod 24 in the first groove 23 distributed at equal intervals on the first disc 22 is activated. Its output end passes through the first disc 22 and pushes the connecting seat 25 and the moving wheel 26 inside, which is connected by a wheel axle and whose wheel surface protrudes from the outside of the connecting seat 25, to extend. The moving wheel 26 with anti-slip texture can increase the friction with the pipe wall and ensure that the device moves stably in the pipeline. Electromagnetic brake pads are provided in the connecting seat 25. When the main device 3 is activated, the electromagnetic brake pads in the connecting seat 25 move synchronously. The axle of wheel 26 prevents the moving wheel 26 from rotating and creates static friction (rather than sliding friction) with the pipe wall, thereby effectively constraining the power output direction of drive motor 31. This ensures that the power of drive motor 31 is directionally transmitted to cleaning component 39, and with the help of traction rope 1, the entire device moves inside the pipeline. The moving device 2 can adjust the extension length of moving wheel 26 through the first electric push rod 24 to adapt to pipes of different diameters. The ring-shaped, equally spaced moving wheels 26 ensure the stability of the device during movement, and the welding fixing method enhances the overall connection strength, enabling the device to move smoothly and reliably inside the gas pipeline, providing a good foundation for cleaning operations.

[0025] It should be noted that this utility model is a gas pipeline cleaning device. When the gas pipeline cleaning device is working, the device is first placed into the gas pipeline by the traction rope 1. The first electric push rod 24 in the first groove 23 of the first disc 22 of the moving device 2 is activated, pushing the connecting seat 25 and the moving wheel 26 to extend, so that the moving wheel 26 contacts the inner wall of the pipeline, driving the device to move in the pipeline. The drive motor 31 in the main device 3 works, and the first gear 32 at its output end meshes with the second gear 34, causing the rotating rod 33 to drive the second disc 35 to rotate. The power box 37 supplies power to all components. The second electric push rod 381 in the scraper assembly 38 in the upper and lower second grooves 36 pushes the first mounting seat 382 and the first fixing block 3 The scraper blade 384 extends and, as the second disc 35 rotates, scrapes away the harder dirt on the inner wall of the pipe. The third electric push rod 391 in the cleaning component 39 in the second groove 36 on the front and rear sides pushes the second mounting base 392, the second fixing block 393, the cleaning plate 394 and the brush strip 395 to extend, further cleaning the inner wall of the pipe. The outer shell 4 protects the internal components. The moving device 2 can adapt to pipes of different diameters, making it convenient for the device to move inside the pipe. The scraper component 38 and the cleaning component 39 in the main device 3 work together to efficiently clean the dirt on the inner wall of the pipe. Moreover, the reasonable connection and power supply of each component ensures the stability and reliability of the device operation, improving the efficiency and effect of gas pipeline cleaning.
