Description

Technical Field

[0001] This utility model relates to the field of dredging technology, specifically a water conservancy dredging machine for riverbed dredging. Background Technology

[0002] Riverbed dredging is an important measure to maintain river health, improve water quality, and prevent floods. With the development of technology, modern riverbed dredging operations have evolved from traditional manual cleaning to using various mechanical equipment for efficient and precise operations.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN222349801U) discloses a water-based dredging machine for riverbed dredging. The machine includes a placement plate, with a placement block fixedly connected to the center of the upper surface of the placement plate. A drain pipe is fixedly connected to the lower part of the front outer wall of the placement block, and a suction pipe is fixedly connected to the upper part of the rear outer wall of the placement block. A sewage pump is fixedly connected to the rear end of the placement block, and a water pump is fixedly connected to the front end of the placement block. A placement groove is formed at the center of the upper surface of the placement block, and a limit block is fixedly connected to the front end of the bottom surface of the placement groove. Compared to traditional water-based dredging machines for riverbed dredging, this utility model features a connecting frame. Under the action of springs, the connecting frame can control the suction block to maintain a relatively close contact with the bottom of the river, thereby improving the efficiency of the dredging machine in suctioning silt and thus increasing its overall working efficiency.

[0004] Although the aforementioned patent describes a water-based dredging machine with a connecting frame, which, under the action of springs, ensures the suction block remains in close contact with the riverbed, thus improving the efficiency of the dredging machine in suctioning silt and consequently increasing its overall efficiency, the silt contains stones that can easily cause blockages during riverbed dredging, leading to decreased efficiency. It also makes it difficult to break up stones in the silt while dredging, reducing blockages and ensuring smoother dredging operations.

[0005] Therefore, this utility model provides a water conservancy dredging machine for riverbed dredging to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] 1. The cleaning mechanism can break up stones or hard blocks mixed in with the silt during the dredging process, which can easily clog the dredging equipment and affect normal dredging. The cleaning mechanism can break up the stones or hard blocks, ensuring that the mud can be smoothly pumped and transported, thereby speeding up the entire dredging process. The cleaning mechanism can effectively break up larger particles, allowing more sediment to be processed by existing equipment, increasing the dredging volume per unit time. Stones and other hard objects entering the sewage pump may cause serious wear or even damage to key components such as pipes. By breaking up these hard blocks in advance, the wear rate of the equipment can be significantly reduced and the service life can be extended.

[0019] 2. By using the installed uprights, A-compression springs, B-compression springs, and electric push rods, the position of the suction pipe can be adjusted according to the height of the silt on the riverbed, ensuring close contact between the suction pipe and the silt surface. Since the silt thickness may vary in different areas, flexibly adjusting the position of the suction pipe can ensure that the entire riverbed is cleaned evenly and effectively, leaving no dead corners and improving the dredging effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a water conservancy dredging machine for riverbed dredging, such as... Figures 1-5 As shown, the water conservancy dredging machine for riverbed dredging includes a base plate 1. Uprights 2 are inserted around the upper surface of the base plate 1. A support plate 3 is fixedly connected to one end of the uprights 2. A collection box 4 is fixedly connected to the upper surface of the support plate 3. A discharge pipe 5 is fixedly connected to one side of the collection box 4. A sewage pump 6 is fixedly connected to one end of the discharge pipe 5. A connecting pipe 7 is fixedly connected to one end of the sewage pump 6. A cleaning mechanism is fixedly connected to one end of the connecting pipe 7.

[0029] The cleaning mechanism includes a housing 8, the upper surface of which is fixedly connected to the bottom of the connecting pipe 7. An annular frame 9 is fixedly connected inside the housing 8, and a micro drive motor 10 is fixedly connected to the upper surface of the annular frame 9. A rotating rod 11 is splined to the output end of the micro drive motor 10, and a cutting blade 12 is fixedly connected to the outer surface of the rotating rod 11. The upper surface of the annular frame 9 has slots for fixing and installing the cutting blade 13. During riverbed dredging, stones or hard lumps may be mixed in with the silt, easily clogging the dredging device and affecting normal dredging. The cleaning mechanism can break up these stones or hard lumps, ensuring smooth extraction and transport of the slurry, thus accelerating the entire dredging process. The cleaning mechanism can effectively break up larger particles, allowing more sediment to be processed by existing equipment, increasing the dredging volume per unit time. Stones and other hard objects entering the sewage pump 6 may cause serious wear or even damage to key components such as pipes. By pre-breaking these hard lumps, the wear rate of the equipment can be significantly reduced, extending its service life.

[0030] A compression spring 14 is fixedly connected to the bottom of the support plate 3, and a compression spring 15 is fixedly connected to the bottom of the base plate 1. The position of the suction pipe 20 can be adjusted according to the height of the silt on the riverbed, so that the suction pipe 20 is in close contact with the silt surface on the riverbed. The thickness of silt in different areas may be inconsistent. By flexibly adjusting the position of the suction pipe 20, the entire riverbed can be cleaned evenly and effectively without leaving any dead corners, thus improving the dredging effect.

[0031] A connecting plate 16 is fixedly connected to the outer surface of the upright 2. An electric push rod 17 is fixedly connected to the upper surface of the connecting plate 16. When the electric push rod 17 is raised or lowered, it drives the connecting plate 16 to be raised or lowered. The connecting plate 16 drives the upright 2 to be raised or lowered. The upright 2 presses the B compression spring 15, which presses against the base plate 1. The base plate 1 then presses the A compression spring 14, which presses against the support plate 3, thereby adjusting the height of the base plate 1.

[0032] The bottom of the pole 2 is fixedly connected to a caster wheel 18. The caster wheel 18 is internally connected to a brake pad, which allows the dredging device to be moved to the river channel that needs dredging, thus improving convenience.

[0033] The bottom of the outer casing 8 is fixedly connected to the feed pipe 19, and one end of the feed pipe 19 is fixedly connected to the suction pipe 20. The bottom of the suction pipe 20 is provided with a suction groove, and the upper surface of the suction pipe 20 is fixedly connected to the connecting frame 21. The upper surface of the connecting frame 21 is fixedly connected to the bottom of the base plate 1. The sewage pump 6 sucks in the silt from the inside of the river through the suction pipe 20. The silt enters the feed pipe 19 from the suction pipe 20 and then enters the outer casing 8 from the feed pipe 19.

[0034] The other side of the collection box 4 has a hole, and a water outlet pipe 22 is fixedly connected inside the hole. The water outlet pipe 22 can discharge the water source to achieve the effect of secondary utilization.

[0035] The front of the collection box 4 has an outlet groove, and a sealing plate 23 is inserted into the outlet groove. A tension rod 24 is fixedly connected to the back of the sealing plate 23. A scraper 25 is fixedly connected to one end of the tension rod 24. Slider 26 is fixedly connected to both sides of the bottom of the scraper 25. A filter plate 27 is slidably connected to the outer surface of the slider 26. The outer surface of the filter plate 27 is fixedly connected to the inside of the collection box 4. The filter plate 27 is used to separate water and silt into wet and dry parts, which facilitates better cleaning of silt.

[0036] Specifically, the dredging device is moved to the river channel requiring dredging via the casters 18. Based on the height of the silt, the electric push rod 17 is activated. As the electric push rod 17 rises and falls, it drives the connecting plate 16 to rise and fall, which in turn drives the upright 2 to rise and fall. The upright 2 compresses the B compression spring 15, which in turn presses against the base plate 1. The base plate 1 then compresses the A compression spring 14, which in turn presses against the support plate 3, thereby adjusting the height of the base plate 1. After the height of the base plate 1 is adjusted, the suction pipe 20 will rise and fall. Subsequently, the sewage pump 6 is activated, drawing the silt from the river channel through the suction pipe 20. The silt enters the feed pipe 19 from the suction pipe 20 and then into the outer casing 8. The micro drive motor 10 is then activated, and its rotation drives the rotating... The rotating rod 11 and the cutting blade 12 rotate, and the cutting blade 12 breaks up large particles of impurities in the sludge. When the sludge passes through the annular frame 9, the internal blades 13 disperse the sludge, preventing it from clogging the sewage pump 6. This ensures that the sludge is smoothly extracted and transported, thereby speeding up the entire sludge removal process. Subsequently, the broken sludge enters the discharge pipe 5 from the sewage pump 6 and falls into the collection box 4. The filter plate 27 in the collection box 4 separates the sludge into wet and dry parts. The sludge remains on the filter plate 27, while the water flows out from the filter plate 27 and out through the water outlet pipe 22. When the sludge needs to be cleaned, the sealing plate 23 is pulled outward. When the sealing plate 23 is pulled out, the scraper 25 is moved by the tension rod 24. The scraper 25 scrapes the sludge on the filter plate 27 through the slider 26, thus removing the sludge and cleaning it.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
