Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a water conservancy pipeline used in water conservancy projects. Background Technology

[0002] In existing water conservancy projects, water pipelines often contain sludge and other impurities during water transport. These impurities are typically filtered through internal filter plates. While this design can purify the water and ensure smooth flow to some extent, the filter plates are prone to clogging with sludge and impurities over time. Clogging not only reduces filtration efficiency but can also decrease the overall water transport capacity of the system, potentially leading to system malfunctions or requiring frequent maintenance and cleaning.

[0003] To alleviate this problem, some designs attempt to use the kinetic energy of the water flow itself to drive the cutting device, hoping to reduce the entry of large particles into the filter plate area. However, simple cutting devices driven by water flow often suffer from low cutting efficiency. Due to changes in water velocity and pressure, especially under low flow conditions, these cutting devices cannot provide sufficient power to effectively break up larger impurities, thus failing to fundamentally solve the problem of filter plate clogging. Utility Model Content

[0004] The purpose of this utility model is to provide a water conservancy pipeline for water conservancy projects, so as to solve the problems that filter plates in traditional water conservancy pipelines are easily blocked by sludge and impurities, and that the cutting efficiency of cutting large particles of impurities by relying solely on the cutting blade driven by water flow is not high.

[0005] To achieve the above objectives, a water conservancy pipeline for water conservancy projects is provided, including a water conveying pipe with connectors at both ends. A groove is provided at the bottom of one end of the water conveying pipe, and a detachable impurity collection cylinder is provided on the groove. A fixing ring is fixedly provided at the inlet end of the groove inside the water conveying pipe. A rotating shaft is rotatably provided at the center of the fixing ring. A rotating fan blade is provided at one end of the rotating shaft, and a cutting blade is provided on the other side of the rotating fan blade on the rotating shaft.

[0006] The angle of attack of the rotating fan blades is set to 15 degrees to effectively utilize the energy of the water flow to increase the rotational speed of the shaft.

[0007] As a further improvement to this technical solution, a filter plate is provided inside the water supply pipe at one end of the outlet, and the filter plate has several water-permeable holes.

[0008] As a further improvement to this technical solution, one side edge of the filter plate is inserted into the inner wall of the impurity collection cylinder where it meets the opening, so as to effectively collect impurities into the impurity collection cylinder.

[0009] As a further improvement to this technical solution, one end of the rotating shaft extends to one side of the filter plate, and an L-shaped scraper is rotatably provided at the contact end with the filter plate.

[0010] As a further improvement to this technical solution, a shaft plug is provided at the other end of the shaft.

[0011] As a further improvement to this technical solution, two symmetrical support frames are provided on the water supply pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In water conservancy pipelines used in water conservancy projects, the rotating fan blades, with their 15-degree angle of attack design, effectively utilize the energy of the water flow to drive their own high-speed rotation, which in turn drives the cutting blades on the same shaft to rotate at high speed. When water containing impurities flows through, the rotating fan blades first guide the water flow and increase its velocity, so that larger particles of impurities are quickly carried to the high-speed rotating cutting blades. The cutting blades then use their rotational kinetic energy to efficiently break up these impurities, preventing large particles from entering the filter plate area and causing blockage, thereby achieving effective purification of the water flow and protection of the filter plates. This mechanism not only improves the efficiency of impurity treatment but also ensures the long-term stable operation of the water conveyance system.

[0014] 2. In this water conservancy pipeline used in water conservancy projects, an L-shaped scraper is installed at one end of a rotating shaft, extending to one side of the filter plate. When the shaft rotates at high speed driven by rotating fan blades, the L-shaped scraper also rotates. This design allows the L-shaped scraper to closely adhere to the filter plate surface, effectively scraping away fine impurities adhering to the filter plate and guiding them to the impurity collection cylinder. Through this mechanism, the L-shaped scraper not only reduces the risk of clogging caused by the accumulation of fine impurities on the filter plate but also maintains the water permeability of the filter plate, ensuring smooth water flow and further improving the overall system's operating efficiency and maintenance convenience. This design significantly enhances the filter plate's self-cleaning ability, extends its service life, and ensures the long-term stable operation of the water conveyance system.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0024] Please see Figure 1 As shown, the purpose of this embodiment is to provide a water conservancy pipeline for water conservancy projects, including a water conveyance pipe 1. A groove 5 is provided at the bottom of one end of the water conveyance pipe 1, and an impurity collection cylinder 4 is detachably installed on the groove 5 for pre-collecting larger particles of impurities, reducing the burden on the subsequent filtration system and facilitating cleaning. A special feature is that, as... Figure 2 As shown: A fixing ring 8 is installed at one end of the water inlet of the trough 5, and a rotating shaft 6 is rotatably installed in the center. A rotating fan blade 13 and a cutting blade 7 are mounted on the rotating shaft 6. Figure 4As shown: The rotating fan blade 13, with its 15-degree angle of attack design, effectively utilizes the energy of the water flow to drive its own high-speed rotation, thereby driving the cutting blade 7 on the same rotating shaft 6 to rotate at high speed. When water containing impurities passes through, the rotating fan blade 13 first guides the water flow and increases the flow velocity, so that larger particles of impurities are quickly carried to the high-speed rotating cutting blade 7. The cutting blade 7 then uses its rotational kinetic energy to efficiently break up these impurities, preventing large particles from entering the filter plate 9 area and causing blockage, thereby achieving effective purification of the water flow and protection of the filter plate 9.

[0025] Furthermore, to further enhance the self-cleaning capability of the filter plate 9, an L-shaped scraper 11 is rotatably mounted on one side of the filter plate 9 at one end of the rotating shaft 6, and a shaft plug 10 is mounted on the other end of the rotating shaft 6. As the rotating fan blade 13 drives the rotating shaft 6 to rotate at high speed, the L-shaped scraper 11 also rotates accordingly. This design allows the L-shaped scraper 11 to closely adhere to the surface of the filter plate 9 for cleaning, effectively scraping away fine impurities attached to the filter plate 9 and guiding them to the impurity collection cylinder 4. Through this mechanism, the L-shaped scraper 11 not only reduces the risk of clogging of the filter plate 9 due to the accumulation of fine impurities, but also maintains the water permeability of the filter plate 9, ensuring smooth water flow and further improving the operating efficiency and maintenance convenience of the entire system.

[0026] In addition, connectors 2 are provided at both ends of the water supply pipe 1 for easy connection to other pipes or equipment. A support frame 3 is installed outside the water supply pipe 1 to ensure the stability of the overall structure and ease of installation. Figure 3 As shown: The filter plate 9 is located at one end of the outlet of the groove 5, and has several water-permeable holes 12 on it to ensure water purification while allowing water to flow smoothly. One side edge of the filter plate 9 is inserted into the inner wall of the impurity collection cylinder 4 where it meets the opening, so that impurities are more effectively collected into the impurity collection cylinder 4 after being cut, further improving the impurity collection efficiency.

[0027] In summary, through the synergistic effect of the rotating fan blade 13, the cutting blade 7, and the L-shaped scraper 11, this invention not only solves the problem of filter plate 9 being easily clogged by sludge and impurities, but also significantly improves impurity treatment efficiency, enhances water purification capacity, ensures long-term stable operation of the water conveyance system, reduces maintenance costs, and extends equipment lifespan. This design provides a more reliable and efficient solution for water conservancy projects.

[0028] Working Principle: Water first enters the water supply pipe 1 through connector 2 and is guided to the detachable impurity collection cylinder 4 when passing through slot 5, where larger particles of impurities are initially collected. Subsequently, the water flow impacts the rotating fan blade 13, whose unique 15-degree angle of attack design allows it to fully utilize the water flow energy to drive its own high-speed rotation, thereby driving the cutting blade 7 on the same rotating shaft 6 to rotate rapidly. The cutting blade 7 efficiently breaks up large particles of impurities flowing through, preventing them from clogging the subsequent filter plate 9. Simultaneously, one end of the rotating shaft 6 extends to one side of the filter plate 9, and the L-shaped scraper 11 rotates close to the surface of the filter plate 9, effectively removing attached fine impurities and guiding them to the impurity collection cylinder 4. The filter plate 9 has multiple permeable holes 12 to ensure smooth flow of purified water. The entire system is securely fixed inside the water supply pipe 1 by a fixing ring 8, while the support frame 3 ensures the stability of the overall structure. This design not only significantly reduces the risk of filter plate 9 clogging but also improves impurity treatment efficiency and ensures the long-term stable operation of the water supply system.
