Description

Technical Field

[0002] Pipeline cleaning is an indispensable part of industrial production and urban infrastructure maintenance. It mainly relies on two methods: manual cleaning and chemical cleaning. Manual cleaning requires workers to enter the pipeline to perform operations, which is not only labor-intensive but also poses extremely high safety risks, especially in flammable and explosive environments. Chemical cleaning is a pipeline cleaning method that injects cleaning agents into the pipeline and uses chemical reactions to remove dirt on the inner wall of the pipeline.

[0003] A pipeline dredging robot with announcement number CN209194692U only needs three people to complete the dredging work, thereby reducing the cost of pipeline dredging. It has high safety. The equipment only needs personnel to operate on the ground, thus avoiding the occurrence of safety accidents. At the same time, it is convenient and efficient. The pipeline dredging robot is used to automatically perform dredging work through manual operation. However, during use, dredging may be affected by the nature of the sludge and the shape of the pipeline. If the sludge is too hard or the humidity is too high, the crushing effect may not be ideal, and when the humidity of the sludge is too high, it may adhere to the inner wall of the collecting wheel, reducing the cleaning efficiency of the device.

[0048] In this technical solution, Figure 1 As shown, the technical solution utilizes the setting of the transverse plate 1712 and the roller 1713. When adjusting the dredging belt 1724, the roller 1713 will first fit with the side wall of the pipe, so that the roller 1713 rolls along the side wall of the pipe, and then drives the cleaning roller 1714 to rotate, so as to clean the side wall of the pipe and improve the cleaning efficiency. Since the transverse plate 1712 and the connecting plate 1710 are rotatably connected by a torsion spring, the cleaning roller 1714 can adaptively adjust when encountering irregularities on the inner wall of the pipe, thereby ensuring the continuity and uniformity of the cleaning.

[0049] Its use is as Figure 6-Figure 9 The technical solution shown in the figure, first, when the sediment is hard, the clean water in the water outlet pipe 1726 will be sprayed in front of the silt removal belt 1724 by the water outlet pipe 1726 to soften the sediment, and then the double-axis motor 1705 is turned on, so that the double-axis motor 1705 drives the first bevel gear 1706 to rotate, the first bevel gear 1706 will mesh and drive the second bevel gear 1707 to rotate, and the second bevel gear 1707 will drive the first shaft rod 1708 to rotate, so that the first shaft rod 1708 drives the fixed sleeve 1715 to rotate, and the fixed sleeve 1715 drives the silt removal belt 1724 set on the outside to rotate, so that the silt removal belt 1724 drives the scraper 1725 to rotate, and because the front end of the scraper 1725 is provided with teeth, the sediment in front can be cleaned when the vehicle body 1 moves forward, and the sediment can be pushed from both sides to the middle;

[0050] When the dredging belt 1724 needs to be adjusted, the electric push rod 1703 is started, and the electric push rod 1703 will pull the L-shaped bracket 1716 to move, so that the L-shaped bracket 1716 drives the moving rod 1722 to move, and the moving rod 1722 drives the fixing sleeve 1715 to move, thereby relaxing the tight dredging belt 1724. At the same time, the L-shaped bracket 1716 drives the fixing rod 1717 to move when moving, so that the fixing rod 1717 slides along the inner wall of the fixing sleeve 1715. Since one end of the protruding block 1718 is slidably arranged in the spiral groove 1721, the protruding block 1718 is driven to slide synchronously along the spiral groove 1721 when the fixing rod 1717 moves, so that the fixing sleeve 1715 rotates, and the fixing sleeve 1715 is fixed. The sleeve 1715 will drive the driving gear 1720 to rotate synchronously, so that the driving gear 1720 engages and drives the rack 1709 to slide out along the mounting shell 1702, thereby pushing the connecting plate 1710 to move, so that the connecting plate 1710 drives the second shaft rod 1711, the cross plate 1712, the roller 1713 and the cleaning roller 1714 to move synchronously, and the second shaft rod 1711 will stretch the dredging belt 1724 to both sides to extend it when moving.
