Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering dredging device. Background Technology
[0002] Hydraulic engineering dredging equipment is a specialized mechanical device used to remove, transport, and treat silt, sediment, weeds, and garbage deposited in water conservancy facilities such as rivers, lakes, reservoirs, and canals. Its core function is to efficiently remove silt and other substances deposited on the bottom of water bodies through mechanical, hydraulic, or a combination of both methods, thereby restoring water flow capacity, improving the flood control and irrigation benefits of water conservancy facilities, or improving the quality of the water environment.
[0003] Dredging typically uses centrifugal pumps to generate negative pressure and suck silt into pipes, which is highly efficient. However, the silt is full of a large amount of debris, including but not limited to plastics, stones, and aquatic plants. Therefore, a filter structure is added before the suction pipe. However, in actual use, the screen in the filter structure must be cleaned every two hours. The cleaning components can remove blocky debris, but strip-shaped debris such as aquatic plants will become entangled on the barrier screen, which not only increases the cleaning time but also clogs most of the filter screen, reducing its efficiency in silt extraction. Therefore, there is a need to provide a silt dredging device for water conservancy projects. Utility Model Content
[0004] The purpose of this utility model is to provide a dredging device for water conservancy projects to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is a dredging device for water conservancy projects, comprising:
[0006] The dredging body includes a frame and a suction pipe fixed in the middle of one side of the frame;
[0007] The cleaning and untangling component includes a first bracket threadedly fixed to the inlet of the suction pipe, a through hole extending through the middle of one end of the first bracket, a track threadedly fixed to both ends of the inner ring of the through hole, a shaped metal strip slidably connected to the track, a connecting block fixed to one end of the shaped metal strip, a handle fixed to the center of one end of the connecting block, and a filter screen fixed to the other end of the connecting block.
[0008] Furthermore, the cleaning and untangling component also includes a fixing ring fixed to one end of the filter screen and a memory spring fixedly connected in the middle of the fixing ring, with the other end of the memory spring fixed inside one side of the first bracket.
[0009] Furthermore, the cleaning and untangling component also includes a sliding block slidably connected to one end of the irregular metal strip and a second bracket fixed to both ends of the sliding block.
[0010] Furthermore, the cleaning and untangling component also includes a scraper fixed to one side of the second bracket, an elliptical hole in the middle of the scraper, and fixing posts fixed at both ends inside the through hole, the fixing posts passing through the elliptical hole.
[0011] Furthermore, the sliding block can slide in the middle of the irregular metal strip, causing the scraper in the middle to move left and right.
[0012] Furthermore, there are two scrapers, located on either side of the filter screen.
[0013] Furthermore, it also includes a collection component, which includes a rectangular tube fixed to one side of the through hole, a collection net fixed to the end of the rectangular tube, and a baffle fixed to the opening of the rectangular tube.
[0014] This utility model has the following beneficial effects: When the filter screen is clogged with fibrous debris, pulling the handle causes the connecting block to move outward, which in turn causes the irregular metal strip to move outward. The sliding block moves left and right along with the irregular metal strip, causing the second bracket and the scraper on it to move left and right to cut the surface of the filter screen being pulled out. The memory spring at the other end of the filter screen is stretched.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0026] Please see Figure 1-5 As shown, this utility model is a dredging device for water conservancy projects, comprising:
[0027] The dredging body includes a frame 10 and a suction pipe 11 fixed in the middle of one side of the frame 10.
[0028] The cleaning and untangling components include a first bracket 20 threadedly fixed to the opening of the suction pipe 11, a through hole 21 extending through the middle of one end of the first bracket 20, a track 22 threadedly fixed to both ends of the inner ring of the through hole 21, a shaped metal strip 23 slidably connected to the track 22, a connecting block 24 fixed to one end of the shaped metal strip 23, a handle 25 fixed to the center of one end of the connecting block 24, and a filter screen 26 fixed to the other end of the connecting block 24.
[0029] In the main dredging unit, the frame 10 is the basic support structure, providing a stable installation platform for the device; the suction pipe 11 is fixed to the middle of one side of the frame 10, connected to the negative pressure equipment, responsible for sucking up and transporting the silt from the bottom of the water. The first bracket 20 is the installation base for this component; the through hole 21 provides installation and movement space for other components; the track 22 allows the irregularly shaped metal strip 23 to slide along it; the irregularly shaped metal strip 23 is connected to the connecting block 24, driving its movement; one end of the connecting block 24 is connected to the handle 25 for easy manual operation or connection to other machine structures to achieve automatic cleaning, and the other end is fixed with a filter screen 26 to intercept garbage in the silt.
[0030] The cleaning and untangling components also include a fixing ring 27 fixed to one end of the filter screen 26 and a memory spring 271 fixedly connected in the middle of the fixing ring 27. The other end of the memory spring 271 is fixed inside one side of the first bracket 20.
[0031] The fixing ring 27 fixes the memory spring 271, enhancing its structural stability; the memory spring 271 connects the fixing ring 27 and the first bracket 20, which can automatically reset the filter screen 26 that has been pulled to one side.
[0032] The cleaning and untangling component also includes a sliding block 281 that is slidably connected to one end of the irregular metal strip 23, and a second bracket 28 fixed to both ends of the sliding block 281;
[0033] The second bracket 28 is fixed at both ends inside the through hole 21 and is used to install the sliding block 281. The sliding block 281 is slidably connected to the irregular metal strip 23. When the irregular metal strip 23 moves, it drives the scraper 29 to move left and right to cut the filamentous debris on the surface of the filter screen 26.
[0034] The cleaning and untangling component also includes a scraper 29 fixed to one side of the second bracket 28, an elliptical hole 291 in the middle of the scraper 29, and fixing posts 211 fixed at both ends inside the through hole 21, the fixing posts 211 passing through the elliptical hole 291;
[0035] The sliding block 281 is slidably connected to the irregular metal strip 23. The sliding block 281 can slide in the middle of the irregular metal strip, driving the scraper 29 in the middle to move left and right.
[0036] The scraper 29 has an oval hole 291 that fits onto the fixed post 211. When it moves left and right, it cuts the debris wrapped around the filter screen 26. The fixed post 211 restricts the movement trajectory of the scraper 29 and provides support.
[0037] There are two scrapers 29, located on both sides of the filter screen 26;
[0038] Two scrapers 29 are symmetrically distributed on both sides of the filter screen 26 to ensure that all filamentous debris on both sides of the filter screen 26 can be cleaned.
[0039] Working principle: When the filter screen 26 is clogged with fibrous debris, pull the handle 25. The handle 25 drives the connecting block 24, which in turn drives the irregular metal strip 23 to move outward, thus moving the filter screen 26 outward. As the irregular metal strip 23 moves, the sliding block 281 begins to sway left and right, causing the second bracket 28 and the scraper 29 on it to move left and right to cut the surface of the filter screen 26 that is being pulled out. The memory spring 271 at the other end of the filter screen 26 is stretched. After the fibrous debris is cut, the force applied to the handle 25 is withdrawn, the memory spring 271 tightens, and the filter screen 26 is pulled back.
[0040] This solution speeds up the cleaning process by adding a cleaning component to remove tangled debris, reducing the time wasted cleaning the filter screen 26 and increasing work efficiency, while also reducing disassembly time.
[0041] Furthermore, even after the scraper 29 cuts off the tangled filamentous debris, it will still affect the filter screen 26 if there is no place to collect and store it. Therefore, a limiting component is installed to address this issue.
[0042] Specifically, it also includes a collection component, which includes a rectangular tube 30 fixed to one side of the through hole 21 and a collection net 31 fixed to the end of the rectangular tube 30;
[0043] The rectangular pipe 30 guides the flow of cut debris; the collection net 31 is fixed at the end of the rectangular pipe 30 to collect debris for centralized cleaning, preventing debris from clogging the suction pipe 11 again; and the baffle 32 prevents filamentous debris from falling.
[0044] Working principle: The filamentous waste hanging down from the scraper 29 accumulates on the back of the scraper 29 and enters the rectangular tube 30 along the back of the blade. Moisture makes it stick firmly to it. As it accumulates and enters the rectangular tube 30, it is squeezed into the collection net 31. The baffle 32 only blocks half of the space to prevent filamentous waste from falling. The collection net 31 can be disassembled for cleaning, and the mesh structure does not take up much space.
[0045] This solution uses a collection component to gather the cut filamentous waste and collect it all at once, preventing the filamentous waste from returning to the sludge or clogging the cleaning components, thus further facilitating the cleaning of filamentous waste.
[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
