Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning equipment, in particular to a towing type waterway silt clearing equipment. Background Art
[0002] With long-term accumulation, silt will reduce the water-passing cross-section of the sewer and reduce the drainage capacity, which may easily lead to waterlogging during the rainy season. At the same time, silt is easy to breed bacteria and produce harmful gases, affecting the urban environment and residents' health. Therefore, regular dredging can ensure the smooth flow of pipelines, improve drainage efficiency, reduce sewage overflow, prevent pipeline damage and blockage, and reduce maintenance costs, thereby maintaining the normal operation and good condition of the urban drainage system.
[0003] In the existing technology, when maintenance personnel need to unclog underground drains, they need to open the manhole cover and lower the ladder at the same time. However, in sewers with excessive silt accumulation, the ladder is easy to slip, and it is easy for maintenance personnel to accidentally slip from the ladder and cause injuries. At the same time, the accumulated silt is easy to breed bacteria and emit a foul odor, which is harmful to the health of residents. Traditional technologies mostly remove silt by manual scraping, which is not only inefficient, but also easy for bacteria to enter the body of the cleaning personnel. Utility Model Content

The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
[0021] Example: See Figure 1 - Figure 7 The utility model provides a technical solution: a drag-type waterway dredging equipment, comprising: a bottom shell 1; a scraper box 2, the outer wall of the bottom of the scraper box 2 is threadedly connected to the outer wall of the bottom shell 1; a cover 3, the outer wall of the cover 3 is threadedly connected to the outer wall of the top of the scraper box 2; a pulling device 4, the outer wall of the pulling device 4 is slidably connected to the inner wall of the scraper box 2; the scraper box 2 includes a lower threaded barrel 21, the top of the lower threaded barrel 21 is fixedly connected to a limiting ring 22, and the number of the limiting rings 22 is four The inner wall of the limiting ring 22 is rotatably connected to the scraping device 23, the side wall inside the limiting ring 22 is slidably connected to the pushing ring 24, the top of the limiting ring 22 is fixedly connected to the upper threaded cylinder 25, and a limiting groove 26 is provided in the wall of the limiting ring 22. The four layers of limiting rings 22 have their respective angle settings deflected by ten degrees in sequence, and twelve scraping devices 23 are evenly arranged in each layer of limiting rings 22. Therefore, when observed from top to bottom, the scraping range of the scraping device 23 covers the side wall of the manhole.
[0022] The scraping device 23 includes a triangular block 231, and the two sides of the triangular block 231 are rotatably connected to the inner wall of the limiting ring 22 through a rotating column 232, and the outer wall of the rotating column 232 is fixedly connected to the outer wall of the triangular block 231. The two sides of the triangular block 231 are fixedly connected to the limiting column 233, and the top of the triangular block 231 is fixedly connected to a guide plate 234. In the process of lifting up after stopping the fall, due to inertia, the pulling device 4 is held so that the position is fixed, and the rest of the pulling device 4 is reduced, and the pull rope 41 drives the fixed part on the sliding column 42. The fixed ring 43 squeezes the push ring 24 on the fixed ring 43. At this time, the push ring 24 is prevented from falling, and the other components of the dredging equipment are in a falling state. At this time, the push ring 24 will push the falling scraper device 23 to move, and the scraper device 23 rotates around the rotating column 232 under the limit of the limit ring 22 until the limit column 233 enters the limit groove 26 to prevent the triangular block 231 from further rotation. After the triangular block 231 rotates out, it will scratch the side wall of the manhole. At this time, under the guidance of the guide plate 234, the silt will fall into the interior of the dredging equipment through the triangular block 231.

The wall is threadedly connected to the outer wall of the upper threaded cylinder 25. When in use, the limiting cylinder 13 on the bottom cover 11 and the anti-slip cylinder 33 on the top cover 31 limit the two ends of the sliding column 42 at the same time, so that the range of movement of the sliding column 42 is limited. Since the bottom cover 11 is connected to the lower threaded cylinder 21 through the first threaded groove 12, and the top cover 31 is connected to the upper threaded cylinder 25 through the second threaded groove 32, the bottom shell 1, the scraping box 2 and the sealing cover 3 form a box body, and the scraped sludge can be collected inside the box body.
[0024] The pulling device 4 includes a pull rope 41, the bottom of the pull rope 41 is fixedly connected to a sliding column 42, the outer wall of the sliding column 42 is fixedly connected to a fixing ring 43, the outer wall of the pull rope 41 is slidingly connected to the inner wall of the top cover 31, the outer wall of the sliding column 42 is slidingly connected to the inner wall of the push ring 24, the top of the sliding column 42 is fixedly connected to the end of the compression spring 34 away from the top cover 31, the side wall of the top of the sliding column 42 is slidingly connected to the side wall inside the anti-slip cylinder 33, and the side wall of the bottom of the sliding column 42 is slidingly connected to the side wall inside the limiting cylinder 13.
[0025] Working principle:
[0026] When in use, a scraper box 2 is set to remove the silt on the edge of the manhole waterway. When in use, the manhole cover on the road is unfastened and the dredging equipment is inserted into the sewer. The diameter of the dredging equipment is slightly smaller than the diameter of the manhole. Due to the squeezing of the compression spring 34, the pushing ring 24 is located below the scraping device 23 to prevent the scraping device 23 from opening prematurely. When it descends to near the bottom of the water surface, it stops descending. After that, the user holds the top position of the pull rope 41 of the column pulling device 4, shakes the pulling device 4 up and down, and slowly drags the pull rope 41, so that the dredging equipment slowly rises in the shaking state. In the process of lifting up again after stopping the falling, due to the effect of inertia, the pulling device 4 is held so that the position is fixed. The rest of the pulling device 4 falls, and the pull rope 41 drives the fixing ring 43 on the sliding column 42 to squeeze the pushing ring 24 on the fixing ring 43. At this time, the pushing ring 24 is prevented from falling, and the other components of the dredging equipment are in a falling state. At this time, the pushing ring 24 will push the falling scraping device 23 to move, and the scraping device 23 is within the limit ring 22. The limiter rotates around the rotating column 232 until the limiter column 233 enters the limit groove 26 to prevent the triangular block 231 from rotating further. After the triangular block 231 rotates out, it will scrape the side wall of the manhole. At this time, under the guidance of the guide plate 234, the silt will fall into the silt removal equipment through the triangular block 231. Since the four layers of limit rings 22 have their respective angle settings deflected by ten degrees in sequence, and twelve scraping devices 23 are evenly arranged in each layer of limit rings 22, the scraping range of the scraping device 23 covers from top to bottom. The side wall of the manhole, since the top cover 31 will be close to the sliding column 42 when falling, the compression spring 34 will be squeezed. Since the compression spring 34 is squeezed and generates elasticity, when the falling caused by inertia fails, the compression spring 34 will push the cover 3 upward, thereby making the sliding column 42 tend to move downward. At this time, the fixing ring 43 will no longer squeeze the pushing ring 24, and at this time it is in the process of falling after stopping the lifting. Due to the friction, the scraping device 23 is closed, which facilitates the dredging equipment to rise until the dredging equipment exits the manhole.
[0027] By setting the bottom shell 1 and the cover 3, the scraper box 2 and the pulling device 4 are positioned, making the dredging equipment detachable, which is convenient for the staff to clean the collected silt. When in use, the limiting cylinder 13 on the bottom cover 11 and the anti-slip cylinder 33 on the top cover 31 limit the two ends of the sliding column 42 at the same time, so that the range of movement of the sliding column 42 is limited. Since the bottom cover 11 is connected to the lower threaded cylinder 21 through the first threaded groove 12, and the top cover 31 is connected to the upper threaded cylinder 25 through the second threaded groove 32, the bottom shell 1, the scraper box 2 and the cover 3 form a box body, and the scraped silt can be collected inside the box body, so that the silt no longer falls back into the sewer. At the same time, the bottom shell 1 and the cover 3 are detachable, making it convenient to clean the silt.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
