[0023] Reference Figure 1-Figure 4 , a wetland water eutrophication ecological restoration device, including a bottom plate, a piping device, a centrifugal pump 1, an anaerobic tank 4 and a filter chamber 3. The anaerobic tank 4 can remove most organic pollutants and suspended matter, reduce the pollution load, and is beneficial to the ecological restoration of wetland water eutrophication. The interior of the filter chamber 3 is fixedly connected with a filter plate 11, and one side surface of the filter chamber 3 is fixedly connected with a fixing frame 5 with an L-shaped cross section. A hydraulic cylinder 10 is fixedly provided on the fixing frame 5, and a driving end of the hydraulic cylinder 10 is fixedly connected to a bending rod 2, and one end of the bending rod 2 is fixedly connected to a scraper bar 14. An opening is opened on one side of the filter chamber 3, and a rotating assembly is provided in the opening. The rotating assembly includes a rotating rod 15 rotatably installed in the opening. The cross section of the rotating rod 15 is L-shaped, and a sealing plate 8 is fixedly connected to the rotating rod 15. A sliding assembly is provided on the filter chamber 3.

[0024] The sliding assembly includes a baffle 9 slidably mounted on the filter bin 3, a sealing port 17 is opened on the baffle 9, a first spring 13 is fixedly connected to the baffle 9, the first spring 13 is fixedly connected to the upper surface of the filter bin 3, and a squeezing roller 12 is fixedly connected to the rotating rod 15. The surface of the squeezing roller 12 fits the surface of the baffle 9. During the rotation of the rotating rod 15, the squeezing roller 12 will be driven to deflect downward. Under the elastic force of the first spring 13, the baffle 9 will move vertically downward, and the inner wall of the sealing port 17 will fit the surface of the bending rod 2 and the connection sealing will be good.

[0025] A torsion spring 16 is sleeved on the rotating rod 15, one end of the torsion spring 16 is fixedly connected to the rotating rod 15, and the other end of the torsion spring 16 is fixedly connected to the filter bin 3. After the L-shaped scraper 14 moves, it will move against the surface of the sealing plate 8. The rotating rod 15 and the filter bin 3 rotate relative to each other at the same time, and the torsion spring 16 is deformed. The cross-section of the scraper 14 is L-shaped, and the upper surface of the scraper 14 is set to be an inclined surface. When sewage splashes onto the upper surface of the scraper 14, the sewage will slide along the inclined surface, which can effectively prevent sewage from accumulating on the upper surface of the scraper 14.

[0026] A material guide plate 6 is fixedly connected to one side surface of the filter bin 3. The material guide plate 6 is arranged at an angle. A storage box 7 is arranged on the bottom plate. The cross section of the material guide plate 6 can be set to a concave shape. When the scraper 14 moves, it can push the impurities out of the opening and slide along the surface of the inclined material guide plate 6 to be collected in the storage box 7.

[0027] In the present invention, when a large amount of impurities are accumulated on the surface of the filter plate 11, the hydraulic cylinder 10 drives the bending rod 2 to move, thereby driving the scraper 14 to move inside the filter bin 3. In the initial state, the surface of the scraper 14 is in contact with the inner wall of one side of the filter bin 3. During the movement of the scraper 14, it will move closely against the upper surface of the filter plate 11, thereby scraping off the impurities on the surface of the filter plate 11. After the L-shaped scraper 14 moves, it will move against the surface of the sealing plate 8. The rotating rod 15 and the filter bin 3 rotate relative to each other at the same time, and the torsion spring 16 is deformed. In the initial state, the sealing plate 8 is located inside the opening and seals the opening. After the sealing plate 8 rotates, it will be staggered with the opening, so that the opening is exposed to the outside. When the scraper 14 moves, the impurities can be pushed out of the opening and moved along The surface of the inclined guide plate 6 slides into the storage box 7 for collection. During the rotation of the rotating rod 15, the squeezing roller 12 is driven to deflect downward. Under the elastic force of the first spring 13, the baffle 9 moves vertically downward, and the inner wall of the sealing port 17 fits with the surface of the bent rod 2 and the connection is sealed. There is a one-centimeter interval between the bent rod 2 and the upper surface of the filter plate 11. After the baffle 9 moves downward, it fits with the filter plate 11 and the inner walls of each side of the filter bin 3, with good sealing, which greatly reduces the amount of sewage falling into the storage box 7. When a large amount of impurities are accumulated on the surface of the filter plate 11 due to long-term use, it is convenient to quickly clean the filter plate 11, effectively avoiding the reduction of the filtering effect, which is beneficial to the subsequent filtration treatment of sewage, and then beneficial to the ecological restoration of eutrophication of wetland water bodies.
