Description

Technical Field

[0001] The invention relates to the technical field of pipeline silt removal, in particular to a silt cleaning device used for water conservancy pipelines. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water conservancy pipelines play a very important role in water conservancy projects. In daily use, pipelines are usually used to transport water, and the water is rich in silt impurities. Therefore, silt will inevitably accumulate inside the pipeline. Since the silt has a certain viscosity, the silt will adhere to the surface of the pipeline. Over time, the silt will accumulate in large quantities in the pipeline, which will lead to pipeline blockage. The current method for cleaning silt inside water conservancy pipelines is mainly to use high-pressure water flow to flush out the silt in the pipeline. This method requires a high-pressure water source and is relatively wasteful of water resources.

[0003] When existing water conservancy pipelines transport water, silt will adhere to the entire inner wall of the pipeline. However, due to different flood seasons and long-term influences, the sludge in the upper part of the pipeline has less water content than the sludge in the lower part, and is easy to dry up and thus stubbornly adhere to the inner wall of the pipeline. It is difficult to clean the silt by direct flushing, and it is difficult to reduce the diameter of the silt blocks, resulting in larger silt blocks, which affects the subsequent sewage cleaning effect.

The outer sleeve 611 and the inner slide bar 612 are used to support the scraper and crusher assembly 62. At the same time, under the action of the rotating shaft 42, the scraper and crusher assembly 62 is driven to rotate and scrape the silt. The rebound force generated by the deformation of the elastic support bar 613 makes it easy to meet the cleaning needs of the silt when the scraper and crusher assembly 62 scrapes the silt.

[0044] The scraper and crusher assembly 62 includes a scraper plate 621 fixedly connected to the end of the inner slide rod 612 away from the outer sleeve 611. The outer surface of the scraper plate 621 contacts the inner wall of the water conservancy pipe. The scraper plate 621 rotates continuously to cut and scrape off the sludge. A crushing groove is provided on the outer surface of the scraper plate 621. A cutter 622 is slidably connected to the inner wall of the crushing groove. During the rotation of the cutter 622, the compacted sludge is cut in the scraper plate 621. The scraper plate 621 and the cutter 622 are used to rotate together to continuously crush the sludge on the inner wall of the water conservancy pipe to reduce the block diameter of the compacted sludge. A slide groove 623 is provided on the inner wall of the crushing groove. The inner wall of the cutter 622 A slider 624 is fixedly installed on the upper part and is slidably connected to the inner wall of the slide groove 623. An elastic member 626 is fixedly connected to the outer surface of the slider 624. One end of the elastic member 626 is fixedly connected to a fixed baffle 627 fixedly connected to the inner wall of the slide groove 623.

[0045] When in use, the staff first places the equipment in the water conservancy pipeline, and then installs the frame 2 on the pipeline dredging trolley 1. After the equipment is checked, the equipment is started, and the output shaft of the cylinder 324 is extended and retracted, and the top support sliding seat 325 and the roller 326 move in the support leg 322, and the hinge between the hinge seat 321 and the support leg 322 is coordinated to make the support leg 322 and the moving wheel 323 support the angle, so that the moving wheel 323 contacts the inner wall of the water conservancy pipeline for support, and then moves under the action of the pipeline dredging trolley 1. At the same time, the clean water in the water tank 511 is sucked out by the water guide pump 513 and guided into the conduit 514. The conduit 514 is used to guide the clean water in the water tank 511 into the water transfer chamber shell 515. Under the action of pressure, the water guide pipe 521 is used to transport the clean water in the water transfer chamber shell 515 to the water box 524, and the nozzle is used to spray water. 525 sprays clean water onto the dried and agglomerated silt, and utilizes the output shaft of the driving motor 41 to rotate the rotating shaft 42 and the scraper arc plate 522 to soften the silt while pre-scraping the silt. Then, the scraper plate 621 rotates continuously to cut and scrape the silt. During the rotation of the cutter 622, the agglomerated silt is cut in the scraper plate 621. The agglomerated silt on the inner wall of the water conservancy pipeline is continuously shredded by utilizing the joint rotation of the scraper plate 621 and the cutter 622. The sliding of the slider 624 in the slide groove 623 squeezes the elastic member 626 to deform. The resilience generated by the deformation of the elastic member 626 forces the cutter 622 to slide, thereby destroying the uniformity of the shape of the scraped silt and further reducing the diameter of the silt blocks. After the scraping and cleaning of the agglomerated silt is completed, the shredded silt blocks are flushed out of the pipeline by water flow.
