Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline dredging technology, and in particular to a water conservancy pipeline dredging device with flushing function. Background Technology
[0002] Over long-term use, water pipelines gradually accumulate silt, debris, and scale, which seriously affect water transport efficiency and can even lead to blockages, pipe bursts, and other accidents, increasing maintenance costs and safety hazards. Therefore, pipeline cleaning equipment is needed to remove silt.
[0003] Currently, mechanical dredging devices are widely used in water conservancy pipeline dredging operations. However, the drill bits of existing mechanical dredging devices are usually of fixed size. When dealing with water conservancy pipelines of different diameters, the drill bit must be removed from the pipeline and replaced with a drill bit of the appropriate size to re-drill into the pipeline for dredging operations. This process is not only cumbersome, greatly reducing dredging efficiency and extending the construction period, but also prone to wear and tear on equipment components due to frequent disassembly and reinstallation, increasing equipment maintenance costs. Furthermore, there is a risk of equipment failure or safety accidents due to improper operation during disassembly and reinstallation. At the same time, fixed-size drill bits cannot fit tightly against the inner wall of pipelines of different diameters, easily creating a large number of dredging dead zones during the dredging process, making it difficult to completely remove silt and dirt from the pipe wall, affecting the dredging quality and failing to meet diverse dredging needs. Therefore, improvements are needed to address these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water conservancy pipeline dredging device with a flushing function.

A moving plate is fixedly connected to the output shaft of the cylinder, and a side scraper is fixedly connected to the end of the moving plate by bolts.
[0006] Preferably, the top surface of each movable plate is provided with a telescopic scraper, and one end of the turntable is coaxially fixed to a rotating cylinder that extends into the cylinder body.
[0007] Preferably, a toothed ring is fixedly connected to one end of the rotating drum, a drive gear is meshed on one side of the toothed ring, and a drive motor installed inside the drum is coaxially fixed to one end of the drive gear.
[0008] Preferably, a water pipe is fitted inside the rotating cylinder, one end of the water pipe extends out of the turntable, the cross-section of the end of the water pipe near the rotating cylinder is tapered, and the other end of the water pipe extends out of the outer wall of the cylinder away from the turntable, and the inner wall is provided with internal threads.
[0009] Preferably, the outer wall of the cylinder is equipped with a plurality of brush plates distributed along the axial side on one side of the turntable. The brush plates are arc-shaped and the top surface of each brush plate is covered with a brush.
[0010] Preferably, two telescopic rods are symmetrically fixed at both ends of the bottom surface of the brush plate. The fixed end of the telescopic rod is fixed to the outer wall of the cylinder. A spring is provided between the two telescopic rods. One end of the spring is fixed to the cylinder, and the other end of the spring is fixed to the bottom surface of the brush plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the cylinder, the moving plate, and the side scraper, facilitates flexible adjustment of the side scraper position according to the pipe diameter, improving the adaptability of the dredging device to pipes of different diameters. This allows it to achieve dredging functionality for various pipe diameters without disassembling or replacing parts. Furthermore, the cooperation of the telescopic scraper and the moving plate facilitates further adjustment of the dredging range, reaching deep into pipe corners and improving the ability to remove dirt from the inner wall of the pipe, thereby reducing dredging dead zones. The cooperation of the drive motor, the drive gear, and the gear ring facilitates stable rotation of components such as the turntable and the spiral scraper, improving the continuity of dredging operations. This system effectively removes silt and debris from pipes. The combination of the water pipe and the rotating drum allows for the introduction of high-pressure water into the pipe for flushing after dredging, improving the thoroughness of the dredging process and removing residual silt. The combination of the brush plate, telescopic rod, and spring ensures the brush plate fits snugly against the pipe's inner wall, adapting to changes in pipe shape and improving the cleaning effect on stubborn dirt, thus enhancing the dredging quality. Ultimately, it solves the problems of needing to change drill bits due to different pipe diameters and incomplete dredging caused by incompatible hole diameters during water pipeline dredging, improving the efficiency, convenience, equipment durability, and dredging quality of the operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1-4 This utility model discloses a water conservancy pipeline dredging device with flushing function, comprising a cylinder 1, a turntable 6 rotatably mounted at one end of the cylinder 1, an mounting platform 7 fixedly connected to the axis of the turntable 6, a spiral scraper 2 fixedly mounted on the top surface of the mounting platform 7, and multiple cylinders 9 mounted on the outer periphery of the mounting platform 7 between the spiral scrapers 2. A movable plate 3 is fixedly mounted on the output shaft of the cylinder 9, and a side scraper 4 is fixedly mounted on the end of the movable plate 3 by bolts. The cylinder 9 is of model SC50X50, with good telescopic performance and stable thrust. The spiral scraper 2 and the side scraper 4 are made of high-hardness wear-resistant alloy steel, which can effectively scrape away stubborn silt and debris. This structure drives the movable plate 3 and the side scraper 4 to extend and retract through the cylinder 9, which can flexibly adjust the dredging range according to the pipe diameter, improving the adaptability of the device to pipes of different diameters. The top surface of the movable plate 3 is provided with a telescopic scraper 8, and an extension cylinder is coaxially fixed to one end of the turntable 6. The rotating drum 10 inside the body 1; the telescopic scraper 8 is made of elastic and wear-resistant rubber, which can closely fit the inner wall of the pipe during movement and is not easy to damage the pipe; the cooperation between the rotating drum 10 and the turntable 6 enables the entire dredging component to rotate stably; this structure, by having the telescopic scraper 8 follow the moving plate 3, further expands the dredging coverage area, reaches into the corners of the pipe, effectively reduces dredging dead angles, and improves dredging quality; a toothed ring is fixedly connected to one end of the rotating drum 10, and a drive gear 11 is meshed on one side of the toothed ring. One end of the drive gear 11 is coaxially fixedly connected to a drive motor installed inside the drum body 1; the drive motor model is Y132M-4, which can provide stable and strong power; the meshing transmission between the drive gear 11 and the toothed ring drives the rotating drum 10, turntable 6 and other components to rotate smoothly; this structure ensures the continuous and stable operation of the dredging device, ensures the efficient operation of components such as the spiral scraper 2 and the side scraper 4, and improves the continuity and efficiency of dredging.
[0020] In this invention, a water pipe 12 is fitted inside the rotating drum 10. One end of the water pipe 12 extends out of the turntable 6. The cross-section of the end of the water pipe 12 near the rotating drum 10 is tapered, and the other end of the water pipe 12 extends out of the outer wall of the cylinder 1 away from the turntable 6, with internal threads on its inner wall. The water pipe 12 is made of high-strength PVC material, which has good pressure resistance and corrosion resistance and can withstand high-pressure water flow. The fitting design between the water pipe 12 and the rotating drum 10 allows for simultaneous high-pressure flushing during the device's rotation for sludge removal. This structure introduces high-pressure water flow through the water pipe 12 to flush the scraped sludge, allowing the sludge and debris to be discharged with the water flow, improving the thoroughness of sludge removal and preventing residual sludge from affecting the sludge removal effect. Multiple brush plates 5 are installed on the outer wall of the cylinder 1 on one side of the turntable 6, distributed along the axial side. The brush plates 5 are arc-shaped, and each brush plate 5 has a brush on its top surface. The brush plates 5 are made of high-strength engineering plastic, and the brushes are made of nylon. The brush plate 5 is wear-resistant and has a good cleaning effect. Its arc-shaped design allows it to better fit the inner wall of the pipe. This structure uses the brush plate 5 and the brush to perform secondary cleaning on the inner wall of the pipe, further removing residual dirt, improving the quality of sludge removal, and ensuring that the inner wall of the pipe is clean. Two telescopic rods 13 are symmetrically fixed at both ends of the bottom surface of the brush plate 5. The fixed end of the telescopic rod 13 is fixed to the outer wall of the cylinder 1. A spring 14 is provided between the two telescopic rods 13. One end of the spring 14 is fixed to the cylinder 1, and the other end of the spring 14 is fixed to the bottom surface of the brush plate 5. The telescopic rod 13 is model SA-25X50, and the spring 14 is made of stainless steel, which has good elasticity and durability. The cooperation of the telescopic rod 13 and the spring 14 allows the brush plate 5 to adapt to the shape changes of the inner wall of the pipe. This structure ensures that the brush plate 5 always fits tightly against the inner wall of the pipe, and can effectively clean regardless of whether the inner wall of the pipe is flat or not, further improving the comprehensiveness and thoroughness of sludge removal.
[0021] Working Principle: When this utility model is used, the drive motor first drives the drive gear 11 to rotate. The drive gear 11 meshes with the gear ring at one end of the rotating drum 10, thereby causing the rotating drum 10 to drive the turntable 6 to rotate together. The spiral scraper 2 on the turntable 6 rotates accordingly, scraping and conveying the silt and debris in the pipeline along the pipeline axis, initially cleaning the accumulated materials in the pipeline. During the sludge removal process, depending on the pipe diameter, the cylinder 9 is activated to push the moving plate 3. The moving plate 3 drives the side scraper 4 and the telescopic scraper 8 to extend outward or retract inward together, adjusting the sludge removal range so that the side scraper 4 and the telescopic scraper 8 fit against the inner wall of the pipe with different diameters. When the moving plate 3 moves, the telescopic scraper 8 closely follows. This effectively removes silt and dirt from the inner wall of the pipe. While cleaning, the water pipe 12 is connected to an external high-pressure water source. The high-pressure water flows through the water pipe 12 and sprays out from the cone-shaped outlet at one end of the turntable 6 to wash away the scraped silt, allowing the silt and debris to be discharged from the pipe with the water flow, thus completing the flushing and cleaning operation. In addition, the brush plate 5 on the outer wall of the cylinder 1 is always in close contact with the inner wall of the pipe under the action of the telescopic rod 13 and the spring 14. As the device moves inside the pipe, the brush on the top surface of the brush plate 5 wipes the inner wall of the pipe to further remove residual dirt and ensure thorough cleaning. Throughout the process, all components work together to achieve efficient cleaning and flushing of water pipes of different diameters.

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.
