DETAILED DESCRIPTION

[0030] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0031] Water conservancy project diversion irrigation refers to the process of directing water from water sources (such as rivers, lakes, reservoirs, etc.) to farmland or other areas in need of irrigation for plant growth by constructing a series of water conservancy project facilities.

[0032] Existing water conservancy engineering diversion irrigation devices include water sources, water transfer channels and control units, among which the water source is the starting point of the irrigation device, and the water source can be a river, lake, reservoir, groundwater or other water sources; the channel is used to divert water from the water source to various irrigation areas, and the channel can be in the form of soil, lining or pipe; the control unit is used to control the distribution and stop of water flow.

[0033] In the actual irrigation process, the channel is inevitably designed to have a curved structure at certain positions. In the actual irrigation process, due to the effect of centrifugal force at the bend, the flow rate of water on the outside of the channel will be faster than that on the inside, resulting in severe scouring on the outside and slow flow on the inside. Due to the slow flow rate, the carried silt and suspended matter are easily deposited on the inside of the bend. Therefore, the existing water conservancy project diversion irrigation device is easily blocked at the bend of channel 2.

[0034] The present invention provides a drainage irrigation device for water conservancy projects, such as Figure 1 As shown, it includes a main channel 1 connected to an irrigation water source, a bend 2 is arranged on the main channel 1, and also includes: a support shaft 4, an impeller 3, an installation box 5, a rotating plate 6 and a sludge scraping assembly 7; wherein the support shaft 4 is transversely arranged on the inner side of the bend 2 and one end thereof is connected to the inner wall of the bend 2; the impeller 3 is arranged on the support shaft 4 and close to one end of the outer side of the bend 2; an installation groove corresponding to the main channel 1 is arranged on the inner side of the bend 2, the installation box 5 is arranged in the installation groove, and one end of the support shaft 4 extends out of the bend 2 and then extends into the installation box 5 On the side, a transmission assembly is also arranged on the inner side of the installation box 5, and one end of the transmission assembly is connected to the support shaft 4; the rotating plate 6 is rotatably arranged on the upper side of the installation box 5, and the other end of the transmission assembly is connected to the rotating plate 6. When the support shaft 4 rotates, the rotating plate 6 can be driven to reciprocate through the rotating assembly. When the rotating plate 6 rotates, one side of the rotating plate 6 can face the inner side of the main channel 1; the sludge scraping assembly 7 is arranged on one side of the rotating plate 6 and faces the inside of the bend 2. When the rotating plate 6 reciprocates, it can drive the sludge scraping assembly 7 to scrape the sludge on the inner side of the bend 2.

[0035] like Figure 2 As shown, during irrigation, rapid water flows through the outside of the bend 2, and then the impeller 3 arranged on the outside of the bend 2 rotates under the impact of water. In order to ensure that the impeller 3 can rotate continuously, it is required that the blades on one side of the impeller 3 are located below the water level line, and half of the blades on the upper side are located above the water level line. In this way, when the water flows through, it impacts the blades on the lower side, thereby ensuring that the impeller 3 can rotate continuously.

[0036] When the drainage irrigation device for water conservancy projects disclosed in the present invention is irrigating, the water flows through the bend 2, driving the impeller 3 and the support shaft 4 to rotate continuously. When the support shaft 4 is driven, it can drive the rotating plate 6 to rotate back and forth through the transmission component. Therefore, the sludge scraper component 7 arranged on the rotating plate 6 can scrape the sludge or other impurities on the inner side of the bend 2 as the rotating plate slides back and forth. Therefore, as long as there is water flowing during irrigation, the above-mentioned sludge scraper component 7 can scrape the sludge and impurities retained at the bottom of the bend at any time, thereby effectively reducing the accumulation of sludge or impurities on the inner side of the bend 2. By continuously scraping away the sludge, it is possible to avoid the sludge from clogging the bend.

[0037] Furthermore, if Figure 3-Figure 5 As shown, the transmission assembly disclosed in this embodiment includes a transmission shaft 8, a bevel gear transmission group, two incomplete gears 9 and a disc 10. The transmission shaft 8 is arranged on the inner side of the mounting box 5 and is perpendicular to the support shaft 4. The bevel gear transmission group is arranged between the transmission shaft 8 and the support shaft 4. The specific bevel gear transmission group includes a first bevel gear arranged at the end of the support shaft 4. The transmission shaft 8 is also provided with a second bevel gear meshing with the first bevel gear. The two incomplete gears 9 are respectively located at both ends of the transmission shaft 8. Half of the gear teeth are arranged on the side walls of the two incomplete gears 9, and the gear teeth on the two incomplete gears 9 are arranged opposite to each other. The disc 10 is fixedly arranged on the bottom surface of the rotating plate 6, and gear teeth meshing with the gear teeth on the two incomplete gears 9 are respectively arranged on both sides of the bottom surface of the disc 10. Therefore, when the impeller 3 drives the support shaft 4 to rotate, it can drive the transmission shaft 8 to rotate in sequence through the first bevel gear and the second bevel gear. When the transmission shaft 8 rotates, it drives the two incomplete gears 9 thereon to move, and then drives the disc 10 to reciprocate through the two incomplete gears 9. Therefore, the rotating plate 6 fixedly connected to the disc 10 can also reciprocate with the disc 10.

[0038] Furthermore, if Figure 4 As shown, when the rotating plate 6 reciprocates and drives the sludge scraping assembly to rotate, in order to avoid interference between the rotating plate 6 and the support shaft 4, the rotating plate 6 disclosed in this embodiment is a circular structure, and two groups of sludge scraping assemblies 7 are respectively arranged on the side walls of the rotating plate 6, and the two groups of sludge scraping assemblies 7 are respectively located on both sides of the support shaft 4. Therefore, the rotating angle of the rotating plate 6 is between 30°-50° each time it rotates, and the two groups of sludge scraping assemblies 7 respectively arranged on both sides of the support shaft 4 can completely scrape the sludge inside the entire bend 2, and the two groups of sludge scraping assemblies 7 slide on both sides of the support shaft 4, so the support shaft 4 does not affect the movement of the two groups of sludge scraping assemblies 7.

[0039] Furthermore, if Figure 5-Figure 6As shown, each group of sludge scraping assembly 7 disclosed in this embodiment includes a mounting plate 13, a plurality of first scrapers 11 and a plurality of second scrapers 12. The mounting plate 13 is arranged at the bottom of the rotating plate 6. A plurality of strip-shaped first scrapers 11 are vertically arranged at the bottom of the mounting plate 13. The plurality of first scrapers 11 are arranged along the width direction of the bend 2. The lower end of each first scraper 11 is also provided with a second scraper 12 which is perpendicular thereto and faces the downstream of the bend 2. The bottom surface of the second scraper 12 contacts the bottom surface of the bend 2. Therefore, the first scraper 11 on the sludge scraping assembly 7 can scrape impurities floating in the water. The bottom surface of the second scraper 12 contacts the bottom surface of the bend 2. Therefore, the second scraper 12 scrapes the sludge at the bottom of the bend 2, thereby ensuring that the sludge and impurities inside the bend 2 are completely cleaned.

[0040] In order to further process the sludge, a sludge filter frame 14 is provided on the inner side of the downstream of the bend 2 disclosed in this embodiment, and is slidably connected to the inner wall of the bend 2. The filter frame 14 can slide in the vertical direction, and the side of the filter frame 14 facing the sludge scraping assembly 7 is open. In the initial position, the filter frame 14 is located at the bottom of the bend 2. Finally, after being scraped by the two groups of sludge scraping assemblies 7, all the sludge on the inner side of the bend 2 enters the filter frame 14.

[0041] A flow sensor is provided inside the filter frame 14, and the flow sensor is connected to the control system. A driving component connected to the filter frame 14 is also provided on the upper side of the filter frame 14, and the driving component is connected to the control system. When the driving component drives the filter frame 14 to move, it can drive the filter frame 14 to slide upward and float to the surface of the water; therefore, when the flow sensor detects that the flow rate in the filter frame 14 decreases, it means that there is a lot of silt in the filter frame 14 that needs to be processed, otherwise it will affect the normal water flow. At this time, the filter frame can be driven to slide upward by the driving component, and when the filter frame 14 slides to the upper side of the water surface, the staff will clean the silt inside it in time. In this process, the water flow can flow normally at the bottom of the filter frame 14, thereby avoiding clogging of the bend 2 when there is too much silt inside the filter frame 14.

[0042] The driving assembly includes a bracket arranged on the inner wall of the bend 2, a driving gear is arranged on the side of the bracket, the driving gear is connected to the output shaft of the driving motor, a vertical connecting plate is arranged on the upper side of the filter frame 14, the connecting plate is slidably connected to the inner side of the bracket, and a rack meshing with the driving gear is also arranged on the connecting plate. Therefore, when the driving motor drives the driving gear to rotate, the filter frame 14 can be driven to slide up and down through the rack meshing with it. The driving motor is a forward and reverse motor, so it can drive the filter frame 14 to slide up and down. In order to facilitate the treatment of the sludge in the filter frame 14, a filter basket 15 with a handle is also arranged in the filter frame 14 disclosed in this embodiment. When the filter frame 14 moves to the upper side, the filter basket 15 can be raised to clean the sludge. In addition, the driving motor can be driven by solar energy. A solar panel is arranged on the outer side of the bend 2. The solar panel collects light energy and converts it into electrical energy to supply the driving motor for operation.

[0043] In order to prevent the filter frame 14 and the filter basket 15 from affecting the normal water flow, the filter frame 14 and the filter basket 15 are both made of textile filter materials, so that the water flow can flow normally through the filter basket 15 and the filter frame 14 to the downstream, while the silt remains inside the filter basket 15 or the filter frame 14.

[0044] In summary, in the drainage irrigation device for water conservancy projects disclosed in the present invention, when water flows through the bend 2, the impeller 3 and the support shaft 4 are driven to rotate continuously. When the support shaft 4 rotates, it can drive the transmission shaft 8 to rotate through the first bevel gear and the second bevel gear in sequence. When the transmission shaft 8 rotates, it drives the two incomplete gears 9 thereon to move, and then drives the disc 10 to reciprocate through the two incomplete gears 9. Therefore, the rotating plate 6 fixedly connected to the disc 10 can also reciprocate with the disc 10. Therefore, the sludge scraper assembly 7 arranged on the rotating plate 6 can scrape the sludge or other impurities on the inner side of the bend 2 when the rotating plate 6 slides back and forth. Therefore, as long as water flows through during irrigation, the above-mentioned sludge scraper assembly 7 can scrape the sludge and impurities retained at the bottom of the bend 2 at any time, thereby effectively reducing the accumulation of sludge or impurities on the inner side of the bend 2. By continuously scraping sludge in this way, it can be avoided that the sludge blocks the bend 2.

[0045] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention belong to the protection scope of the present invention.
