Description

Technical Field

[0001] This invention relates to the field of pipeline technology, and in particular to an automated device for cleaning foreign objects from the inner wall of a pipeline. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Fluids are pressurized by a drive motor and flow from high-pressure to low-pressure areas in the pipeline. They can also be transported using their own pressure or gravity. Pipelines are mainly used for water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. After prolonged use, various foreign objects can easily accumulate inside pipelines, causing the inner diameter to narrow and hindering the transport of materials. Various equipment is needed to clean and expand the pipeline. However, existing pipeline expansion devices are difficult to adapt to different pipe specifications, resulting in limited applicability. Furthermore, existing pipeline expansion devices cannot automatically clean foreign objects from inside the pipeline, leading to irreversible pipeline performance after use. Summary of the Invention

The sweeping brush 23 has a fixed plate 2 installed on one side of the movable tube 1. A rotary cylinder 3 is fixedly connected to one side of the fixed plate 2. A first rotating shaft 4 is installed at the output end of the rotary cylinder 3. A first spur gear 5 is fixedly connected to the first rotating shaft 4. A second spur gear 6 is meshed with the first spur gear 5. An internal gear ring 7 is provided inside the movable tube 1 and meshes with the top of the second spur gear 6. A first bevel gear 11 is installed at one end of the first rotating shaft 4. A second bevel gear 12 is distributed and meshed on one side of the first bevel gear 11. A lead screw 13 is installed inside the second bevel gear 12. An internal screw cylinder 14 is threaded onto the lead screw 13. A support plate 15 is fixedly connected to one end of the internal screw cylinder 14. A connecting rod 9 is symmetrically fixed at one end of the movable tube 1. An annular groove 10 is opened on one side of the fixed plate 2, and the connecting rod 9 is sleeved inside the annular groove 10. A second rotating shaft 8 is rotatably connected to one side of the fixed plate 2, and the second spur gear 6 is installed at one end of the second rotating shaft 8. Shaft seats are distributed and fixed at the other end of the movable tube 1. 16, and the lead screw 13 is installed inside the bearing seat 16; guide rods 17 are fixedly distributed on the movable tube 1, and the guide rods 17 are sleeved inside the inner screw cylinder 14; a fixed rod 18 is fixedly connected to one side of the support plate 15, and a mounting seat 19 is fixedly connected to one side of the fixed rod 18; a fourth rotating shaft 20 is rotatably connected inside the mounting seat 19, and a cleaning brush 23 is fixedly connected to the top of the fourth rotating shaft 20; a torsion spring 21 is installed on the fourth rotating shaft 20, and a sliding groove 22 is opened at the top of the mounting seat 19.

[0021] Working principle: When using this invention for pipe expansion, firstly, the movable tube 1 is inserted into the pipe. Then, the rotary cylinder 3 on the fixed plate 2 is activated. The rotary cylinder 3 drives the first bevel gear 11 via the first rotating shaft 4. The first bevel gear 11 drives the lead screw 13 via the second bevel gear 12. The lead screw 13 drives the support plate 15 to unfold via the inner screw cylinder 14 until it presses against the inner wall of the pipe. The support plate 15 drives the mounting base 19 via the fixed rod 18. The mounting base 19 drives the cleaning brush 23 to contact the inner wall of the pipe until it is squeezed, causing the cleaning brush 23 to rotate. This causes the fourth rotating shaft 20 to compress the torsion spring 21. At the same time, the first rotating shaft... 4. The first spur gear 5 drives the second spur gear 6, which in turn drives the movable tube 1 via the internal gear ring 7. The movable tube 1 drives the inner screw cylinder 14 via the guide rod 17. The inner screw cylinder 14 rotates synchronously with the movable tube 1, allowing the support plate 15 and the cleaning brush 23 to remove foreign objects while pressing against the inner wall of the pipe. Then, the device is reset, and the entire device is moved along the pipe and expanded again to clean the inside of the pipe. The second rotating shaft 8 is used to install the second spur gear 6, the connecting rod 9 and the ring groove 10 are used to install the movable tube 1, the shaft seat 16 is used to install the lead screw 13, and the sliding groove 22 is used to install the cleaning brush 23.
