Description

Technical Field

[0001] This utility model belongs to the technical field of municipal drainage dredging equipment, and in particular relates to a dredging device suitable for municipal drainage construction. Background Technology

[0002] Currently, municipal water supply and drainage systems mainly refer to urban water supply (tap water) and drainage (rainwater drainage, sewage drainage, etc.), and pipelines are an important component of these systems, with widespread use. To prevent urban flooding, road waterlogging, sewage overflows in residential areas and other locations, and road submersion during the rainy season, relevant personnel need to use dredging equipment to clean the inside of the pipelines.

[0003] Patent CN221855767U discloses a dredging device suitable for municipal drainage construction. It includes a support frame with a horizontally positioned support rod at the top. A sliding member is slidably mounted on the support rod along its length, and a fixed seat is provided on the sliding member. The fixed seat has a through hole for interlocking with a high-pressure water pipe, which is used to limit the high-pressure water pipe's position on the fixed seat. The support rod has multiple insertion holes arranged at intervals along its length. The sliding member has a locking mechanism for fixing it to the support rod, and the insertion holes allow the locking mechanism to be inserted perpendicular to the length of the support rod. This application effectively reduces manpower and facilitates the smooth operation of dredging work.

[0004] In existing technologies, the difficulty of cleaning and the efficiency of work are reduced by setting a locking mechanism and a support rod. However, the following problems still exist in the overall use: First, when cleaning sludge from pipes, the inside of the pipes contains a large amount of garbage, branches, and fibrous entanglement. If these enter the sludge cleaning device, they will cause damage to the device and affect its service life. Second, when cleaning pipes, existing sludge cleaning devices usually discharge the extracted garbage and sludge together, and then separate the garbage and sludge by water flushing. The process is cumbersome and affects work efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a dredging device suitable for municipal drainage construction. By incorporating a cutting blade, it can cut and break up branches and fibrous materials entangled inside pipes, solving the problem that existing dredging devices often damage the system when large amounts of garbage, branches, and fibrous materials enter the pipes during sludge removal. Furthermore, by incorporating a collection chamber and filter screen, sludge and garbage can be collected separately, addressing the issue that existing dredging devices typically discharge the extracted garbage and sludge together during pipe cleaning, requiring subsequent water flushing to separate the two, a cumbersome process that reduces work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dredging device suitable for municipal drainage construction, comprising a fixed support, a waste cleaning cylinder slidably disposed inside the fixed support, an axial flow water pump disposed at one end of the outlet of the waste cleaning cylinder, a dredging chamber disposed at one end of the inlet of the waste cleaning cylinder below the fixed support, a filter screen disposed inside the dredging chamber, a waste cleaning shell rotatably disposed on the outer surface of the dredging chamber, a collection chamber for collecting impurities disposed between the waste cleaning shell and the dredging chamber, and a plurality of limiting grooves disposed on the outer surface of the waste cleaning shell, each of the plurality of limiting grooves having a scraper slidably disposed inside for cleaning the inner wall of the pipe.

[0007] Preferably, multiple slag inlets are provided on both sides of the outer surface of the multiple scrapers, and one end of the multiple slag inlets is connected to the interior of the collection chamber.

[0008] Preferably, each of the multiple scrapers is provided with a driving component on its top end face, and a driving ring is rotatably provided on the outer surface of the sludge removal chamber above each of the multiple driving components. The bottom end face of the driving ring is provided with a spiral thread. The driving ring is meshed and connected to the driving component. The top end face of the driving ring is provided with a second toothed ring, and a second driving gear is meshed and connected on one side of the second toothed ring.

[0009] Preferably, the top end face of the waste removal shell is provided with a water storage ring, the inside of the water storage ring is provided with a water storage cavity, the water storage cavity is connected to the inside of the waste removal shell, the inside of the waste removal shell is provided with a cavity, and the outer surface of the waste removal shell is provided with multiple water outlet holes.

[0010] Preferably, a telescopic tube is provided on the end face of the water storage ring, and a movable ring is provided on the outer surface of the telescopic tube, the movable ring being rotatably connected to the fixed support.

[0011] Preferably, a first toothed ring is provided on the inner wall of the water storage chamber, and a first drive gear is engaged on one side of the first toothed ring.

[0012] Preferably, the outer surface of the waste removal cylinder is provided with a rack, and the outer surface of the rack is provided with a third drive gear for meshing and transmission.

[0013] Preferably, each of the scrapers has a connecting plate on its bottom end face, the connecting plate being slidably connected to the waste removal shell, and each of the connecting plates has a cutting blade on its bottom end face for cutting off the tangled material.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) By setting up a scraper and a cutting blade, as well as a filter screen and a collection chamber, this utility model can scrape and clean the inner wall of the pipe by rotating the scraper, preventing sludge from adhering to the inner wall surface of the pipe, thereby improving the cleaning effect. By setting up a driving component and a driving ring, the extension distance of the scraper can be adjusted, so that the scraper is close to the inner wall of the pipe, improving the adaptability of the scraper. By setting up a cutting blade, it can cut and break up the branches and fluffy entanglements in the pipe, preventing blockage and damage to the sludge removal device, and improving the overall service life of the device. (2) By setting up a collection chamber, a filter screen, a slag inlet and a water outlet, this utility model can screen the crushed garbage, so that the sludge can be pumped out by the axial flow water pump through the filter screen, and the crushed garbage enters the collection chamber through the slag inlet for temporary collection. This setting can separate and collect sludge and garbage, and discharge the sludge separately, reducing the subsequent garbage screening process, improving work efficiency, and the water outlet can be set up to perform simple cleaning of the device during the rotation of the scraper.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] refer to Figure 1 , Figure 5 and Figure 6 A dredging device suitable for municipal drainage construction includes a fixed support 10, a slidable dredging cylinder 12 inside the fixed support 10, a rack 29 on the outer surface of the dredging cylinder 12, a third drive gear 30 meshing with the outer surface of the rack 29, a housing for mounting the third drive gear 30 on the outer surface of the third drive gear 30, and a first motor on the outer surface of the housing. The output shaft of the first motor is connected to the third drive gear 30. Before use, the device is placed at the pipe opening, ensuring the fixed support 10 is stably positioned on the road surface at the pipe opening. Then, the first motor is started, and its output shaft drives the third drive gear 30 to rotate, which in turn drives the rack 29 to move downwards. The rack 29 drives the waste cleaning cylinder 12 to move downwards. The outer surface of the waste cleaning cylinder 12 is provided with a cross-shaped fixing frame to support and restrict the movement of the waste cleaning cylinder 12, so that the waste cleaning cylinder 12 is in a vertical state and prevents the waste cleaning cylinder 12 from tilting. It should be noted that since the sludge removal structure is located below the waste cleaning cylinder 12, in actual operation, the waste cleaning cylinder 12 and the rack 29 will gradually enter the pipe to be cleaned after the sludge removal structure has completed the sludge removal. At this time, since the sludge in the pipe has been removed, there will be no dirt adhering to the outside of the rack 29, which can ensure that the rack 29 and the third drive gear 30 can mesh smoothly and transmit power. In addition, the rack 29 will be sprayed with anti-rust oil on the outside at regular intervals during actual use, thereby reducing the possibility of rust on the rack 29.

[0018] Further reference Figure 1 , Figure 2 and Figure 3When the waste cleaning cylinder 12 moves downward, an axial flow water pump 13 is installed at one end of the outlet of the waste cleaning cylinder 12, and a sludge cleaning chamber 31 is installed at one end of the inlet of the waste cleaning cylinder 12 below the fixed support 10. A filter screen plate 27 is installed inside the sludge cleaning chamber 31. When cleaning the sludge, the axial flow water pump 13 is started. While the waste cleaning cylinder 12 moves, it can drive the sludge cleaning chamber 31 at the bottom to move downward. At the same time, the sludge cleaning chamber 31 drives the filter screen plate 27 to move downward, so that the filter screen plate 27 comes into contact with the sludge accumulated in the pipe. After the sludge is filtered by the filter screen plate 27, the garbage is screened out. The sludge is drawn away by the axial flow water pump 13 and discharged from the drain of the axial flow water pump 13.

[0019] Further reference Figure 2 , Figure 3 and Figure 4 The outer surface of the sludge removal chamber 31 is rotatably equipped with a waste removal shell 32. A bearing 34 is rotatably installed between the sludge removal chamber 31 and the waste removal shell 32. A collection chamber 28 for collecting impurities is installed between the waste removal shell 32 and the sludge removal chamber 31. The outer surface of the waste removal shell 32 is provided with multiple limiting grooves 17. Scrapers 18 for cleaning the inner wall of the pipe are slidably installed inside the multiple limiting grooves 17. A driving element 21 is provided on the top end face of each of the multiple scrapers 18. A driving ring 22 is rotatably installed on the outer surface of the sludge removal chamber 31 above the multiple driving elements 21. A spiral thread is provided on the bottom end face of the driving ring 22. The driving ring 22 is meshed and connected to the driving element 21. A second toothed ring 25 is provided on the top end face of the driving ring 22. A meshing transmission is provided on one side of the second toothed ring 25. The second drive gear 26 has a mounting base on top of it. A second motor is mounted on the end face of the mounting base. The output shaft of the second motor is connected to the second drive gear 26. When the extension length of the scraper 18 needs to be adjusted, the second motor is started. The output shaft of the second motor drives the second drive gear 26 to rotate. After the second drive gear 26 rotates, it drives the second toothed ring 25 on the outer surface to rotate. This causes the second toothed ring 25 to drive the drive ring 22 at the bottom to rotate. After the drive ring 22 rotates, it drives multiple drive components 21 to move through the vortex thread at the bottom. This causes the multiple drive components 21 to drive the scraper 18 to extend outward from the waste removal shell 32 until the scraper 18 abuts against the inner wall of the pipe, so that the scraper 18 can scrape and clean the inner surface of the pipe.

[0020] Further reference Figure 2 , Figure 3 and Figure 4When it is necessary to remove debris such as branches and fibrous tangles from inside the shredder, a first toothed ring 23 is installed on the inner wall of the water storage chamber 35. A first drive gear 24 is meshed on one side of the first toothed ring 23. A third motor is installed above the first drive gear 24 on the end face of the mounting base. The output shaft of the third motor is connected to the first drive gear 24. When the third motor is started, its output shaft drives the first drive gear 24 to rotate. The rotation of the first drive gear 24 drives the meshing first toothed ring 23 to rotate, causing the first toothed ring 23 to rotate. This causes the first toothed ring 23 to rotate the water storage chamber 35 and the waste removal shell 32. Simultaneously, the waste removal shell 32 drives multiple scrapers 18 to rotate, allowing the scrapers 18 to scrape and clean the inner wall of the pipe, reducing sludge residue and improving efficiency. For effective cleaning, each of the bottom surfaces of multiple scrapers 18 is equipped with a connecting plate 20, which is slidably connected to the waste removal housing 32. Each of the bottom surfaces of the connecting plates 20 is equipped with a cutting blade 19 for cutting tangled materials. As the scraper 18 extends outward, it drives the cutting blade 19 at the bottom to extend outward through the connecting plate 20, allowing the cutting blade 19 to move with the scraper 18. As the scraper 18 rotates, it drives the cutting blade 19 to rotate, thereby cutting and pulverizing the waste inside the pipe and preventing the waste from damaging the device. The outer surfaces of the first motor, second motor, and third motor are all equipped with protective shells. By setting protective shells and mounting bases, it is possible to prevent impurities such as silt from entering and affecting the transmission between multiple gears, thereby improving the overall stability of the device.

[0021] Further reference Figure 1 , Figure 5 and Figure 6 Multiple scrapers 18 have multiple slag inlets 33 on both sides of their outer surfaces. One end of each slag inlet 33 is connected to the interior of the collection chamber 28. As the scrapers 18 rotate, the crushed waste and sludge enter the collection chamber 28 through the slag inlets 33 for temporary storage. The bottom end face of the collection chamber 28 is equipped with an annular filter screen. As waste and sludge continuously enter the collection chamber 28, they push the sludge through the annular filter screen and back into the pipe, waiting to be pumped out by the axial flow water pump 13. This ensures that only waste remains inside the collection chamber 28, thereby separating and discharging the waste and sludge, reducing subsequent sorting processes, and improving work efficiency.

[0022] Further reference Figure 1 , Figure 2 and Figure 3During pipe cleaning, some sludge dries and adheres to the inner wall of the pipe, making it impossible for the scraper 18 to completely remove it. Therefore, a water storage ring 14 is provided on the top end face of the waste cleaning shell 32. The water storage ring 14 has a water storage chamber 35 inside, which is connected to the inside of the waste cleaning shell 32. The inside of the waste cleaning shell 32 has a cavity, and the outer surface of the waste cleaning shell 32 has multiple water outlet holes 16. A telescopic pipe 15 is provided on the end face of the water storage ring 14, and a movable ring 11 is provided on the outer surface of the telescopic pipe 15. The movable ring 11 is rotatably connected to the fixed support 10. An external water pump and water pipe are connected to the inlet end of the telescopic pipe 15, and the water pump is started to inject water into the inside of the telescopic pipe 15. The water enters the inside of the water storage chamber 35 through the telescopic pipe 15 and is sprayed out through the water outlet 16, thereby softening the dried sludge on the inner wall of the pipe, making it easier for the scraper 18 to scrape it off, improving the cleaning effect. The cleaning water entering the inside of the pipe will dilute the sludge, making it easier for the axial flow water pump 13 to remove the sludge and reduce energy consumption. By setting the movable ring 11, the telescopic pipe 15 can rotate together with the water storage ring 14, continuously delivering cleaning water to the inside of the water storage chamber 35.
