Description

Technical Field

[0001] This utility model relates to the field of aqueduct technology, and in particular to a self-cleaning and leak-proof aqueduct structure. Background Technology

[0002] An aqueduct is an elevated water channel that transports water across rivers, valleys, depressions, and roads. It is commonly used for irrigation, flood control, and sediment removal. Large aqueducts can also be navigable. Aqueducts are mainly constructed of materials such as masonry, concrete, and reinforced concrete. While current aqueducts effectively transport water, there are still areas for improvement, such as: ordinary aqueducts do not have seepage prevention and filtration functions.

[0003] Chinese Patent CN219886697U discloses a leak-proof aqueduct structure, comprising an integral device body. This integral device body includes a concrete base and an aqueduct, with the concrete base located at the bottom and the aqueduct at the top. In this invention, through a leak-proof layer and a filtration mechanism, when water is transported using the integral device body, filter screens are provided on the longer outer sides of the filtration mechanism, and the filtration mechanism and filter screens are internally connected. This allows solid waste in the water to be intercepted during transport, facilitating subsequent cleaning by sanitation workers, while simultaneously cleaning water resources and protecting the environment. Furthermore, the U-shaped leak-proof layer inside the aqueduct prevents leakage during water transport, effectively solving the problem that ordinary aqueducts lack leak-proof and filtration functions.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: after the structure intercepts garbage through the filter, it needs to be cleaned manually, and if manual cleaning is not timely, garbage will accumulate at the filter and easily cause blockage. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to improve the problem of inconvenient cleaning after the existing aqueduct filter screen structure intercepts garbage.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A self-cleaning, leak-proof aqueduct structure includes several aqueduct bodies connected in sequence. The aqueduct bodies are semi-circular, with a filter cylinder fixedly connected to the inner wall of each body. A rotating shaft is axially connected to the filter cylinder, and a cleaning assembly is mounted on the rotating shaft. This cleaning assembly includes a scraper, an impeller, and a drain outlet. The two ends of the rotating shaft are located inside and outside the filter cylinder, respectively. The scraper is located at the end of the rotating shaft inside the filter cylinder, with the end of the scraper away from the rotating shaft contacting the inner wall of the filter cylinder. The impeller is located at the end of the rotating shaft outside the filter cylinder, and the drain outlet is located on the surface of the filter cylinder, with the drain outlet positioned higher than the aqueduct body.

[0008] Furthermore, the surface of the aforementioned scraper is provided with drainage holes arranged in a matrix.

[0009] Furthermore, the scraper includes a fixed end and a sliding end, the fixed end and the sliding end are slidably connected, the fixed end is connected to the rotating shaft, the end of the sliding end away from the fixed end contacts the inner wall of the filter cylinder, and an elastic element is provided between the fixed end and the sliding end.

[0010] Furthermore, the aforementioned elastic element includes a support spring, with the fixed end and the sliding end respectively connected to both ends of the support spring.

[0011] Furthermore, the aforementioned scrapers are a plurality of blades evenly spaced along the circumference of the aforementioned rotation axis.

[0012] Furthermore, both ends of the aforementioned aqueduct body are provided with connecting components, each including a connecting sleeve. Each connecting sleeve has a slot at both ends for insertion of the adjacent aqueduct body.

[0013] Furthermore, the slot is equipped with a sealing gasket, and the top of the connecting sleeve is connected to the aqueduct body by bolts through a drilling installation method.

[0014] Furthermore, several sealing grooves are respectively opened on both sides of the connecting sleeve, and a sealing layer is provided inside the sealing groove.

[0015] Furthermore, the aforementioned sealing layer is formed by sealing with sealant or by pouring concrete.

[0016] Furthermore, mounting grooves are provided on both sides of the connecting sleeve, and cover plates are installed on the mounting grooves. The cover plates are connected to the connecting sleeve by bolts.

[0017] The beneficial effects of this utility model are:

[0018] (1) Impurities in the water are filtered through the filter cylinder, and the impurities remain in the filter cylinder. The impact force of the water flow acts on the blades, which drives the rotating shaft to rotate, so that the scraper can rotate and push the impurities below the filter cylinder to the drain outlet, and automatically slide out of the filter cylinder from the drain outlet, realizing the automatic discharge of impurities and preventing accumulation. Compared with the existing technology, it saves the number of manual cleanings.

[0019] (2) By inserting the aqueduct body into the slot and performing initial sealing with a sealing gasket, and then performing multi-layer sealing on the aqueduct body and connecting sleeve with a sealing layer, the sealing and leakage effect between the aqueduct body and the connecting sleeve is improved. The cover plate can protect the sealing layer, reduce the erosion and impact of water flow on the sealing layer, and extend its service life. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-5As shown in the figure, this application embodiment proposes a self-cleaning and leak-proof aqueduct structure, including a plurality of aqueduct bodies 1 connected in sequence. The aqueduct body 1 is semi-circular. A filter cylinder 2 is coaxially fixedly connected to the inner wall of the aqueduct body 1. A rotating shaft 4 is rotatably connected to the filter cylinder 2. A cleaning component 5 is installed on the rotating shaft 4. The cleaning component 5 includes a scraper 51, an impeller, and a drain port 53. The two ends of the rotating shaft 4 are located inside and outside the filter cylinder 2, respectively. The scraper 51 is located at the end of the rotating shaft 4 located inside the filter cylinder 2. The end of the scraper 51 away from the rotating shaft 4 contacts the inner wall of the filter cylinder 2. The impeller is located at the end of the rotating shaft 4 located outside the filter cylinder 2. The drain port 53 is opened on the surface of the filter cylinder 2, and the position of the drain port 53 is higher than that of the aqueduct body 1.

[0028] First, it should be stated that the filter cartridge 2 filters impurities from the water, and the impurities remain in the filter cartridge 2. The impact force of the water flow acts on the blades 52, which drives the rotating shaft 4 to rotate. This allows the scraper 51 to rotate and push the impurities below the filter cartridge 2 to the drain outlet 53, where they automatically slide out of the filter cartridge 2. This achieves automatic discharge of impurities and prevents accumulation, saving the number of manual cleaning operations compared to existing technologies.

[0029] Specifically, the outer diameter of the filter cylinder 2 is the same as the inner diameter of the aqueduct. The filter cylinder 2 and the aqueduct are tightly connected. The water flowing from the aqueduct can stably flow into the filter cylinder 2. The impeller rotates under the impact of the water flow, thereby driving the coaxial scraper 51 to rotate. The scraper 51 scrapes up and stirs up the garbage and sludge settled at the bottom of the filter cylinder 2 and discharges it outward through the sewage outlet 53, realizing the automatic discharge of impurities and preventing accumulation.

[0030] To ensure the stability of the scraper 51 during rotation and its water-passing performance, the surface of the scraper 51 is provided with drainage holes 55 arranged in a matrix. This allows water to flow through the drainage holes 55 during the rotation of the scraper 51. The drainage holes 55 can quickly discharge the water carried by the scraper 51 when it is above the water surface, while reducing resistance in the water and ensuring the stability and smoothness of the rotation of the scraper 51.

[0031] Furthermore, the scrapers 51 are arranged in multiple evenly spaced circumferentially along the rotation axis 4. The simultaneous rotation of multiple scrapers 51 can improve the efficiency of garbage cleaning.

[0032] In actual operation, there may be a gap between the end of the scraper 51 away from the rotating shaft 4 and the inner wall of the filter cylinder 2, which may result in incomplete scraping of debris at the bottom of the filter cylinder 2. To improve this problem, the scraper 51 includes a fixed end 511 and a sliding end 512, which are slidably connected. The fixed end 511 is connected to the rotating shaft 4, and the end of the sliding end 512 away from the fixed end 511 contacts the inner wall of the filter cylinder 2. An elastic element is provided between the fixed end 511 and the sliding end 512, and the elastic element includes a support. A support spring 54 is provided, with its two ends connected to the fixed end 511 and the sliding end 512, respectively. During actual operation, the support spring 54 acts on the sliding end 512, ensuring that the end of the sliding end 512 away from the fixed end 511 is stably in contact with the inner wall of the filter cylinder 2. This ensures that even after wear occurs, the sliding end 512 remains in contact with the inner wall of the filter cylinder 2 under the action of the support spring 54. Furthermore, the force of the support spring 54 is preset within a certain range to prevent excessive friction between the sliding end 512 and the inner wall of the filter cylinder 2, which could affect the rotation efficiency.

[0033] To reduce the chance of leakage during water transport, connecting components 6 are installed at both ends of the aqueduct body 1. The connecting components 6 include connecting sleeves 61, and slots 62 are opened at both ends of the connecting sleeves 61 for the aqueduct body 1 to be inserted. When installing the aqueduct body 1, the aqueduct body 1 is inserted into the slots 62 and initially sealed by the sealing gasket 7. Then, the aqueduct body 1 and the connecting sleeves 61 are sealed in multiple layers by the sealing layer 64 to improve the sealing and leakage prevention effect between the aqueduct body 1 and the connecting sleeves 61.

[0034] The slot 62 has a sealing gasket 7 inside, and the top of the connecting sleeve 61 is connected to the aqueduct body 1 by bolts through a drilling installation method.

[0035] Several sealing grooves 63 are provided on both sides of the connecting sleeve 61, and a sealing layer 64 is provided inside the sealing groove 63.

[0036] The sealing layer 64 is formed by sealing with sealant or by pouring concrete, or a combination of both. To save construction time, sealant can be selected.

[0037] The connecting sleeve 61 has mounting grooves 65 on both sides, and a cover plate 66 is installed on the mounting groove 65. The cover plate 66 is connected to the connecting sleeve 61 by bolts. After the sealing layer 64 is installed, the cover plate 66 is fixed in the mounting groove 65 to protect the sealing layer 64, reduce the erosion and impact of water flow on the sealing layer 64, and extend its service life.

[0038] Working principle: When installing the aqueduct body 1, the aqueduct body 1 is inserted into the slot 62 and initially sealed by the sealing gasket 7. Then, the sealing layer 64 is used to seal the aqueduct body 1 and the connecting sleeve 61 in multiple layers, which improves the sealing and leakage effect between the aqueduct body 1 and the connecting sleeve 61. The sealing layer 64 is formed by sealing with sealant or by pouring concrete, or a combination of both. To save construction time, sealant can be used. After the sealing layer 64 is installed, the cover plate 66 is fixed in the installation groove 65 to protect the sealing layer 64, reduce the erosion and impact of water flow on the sealing layer 64, and extend its service life.
