The utility model accelerates the decomposition of organic matter and purifies water quality by planting emergent plants, filters urban sewage in the sewage pipe through the filter grid, prevents indiscriminate discharge, reduces the burden on the river channel through the cooperation of multiple filter grids, and facilitates the cleaning of the river channel through the cooperation of the first filter net and the second filter net.

[0004] The above-mentioned prior art solution has the following defects: although the above-mentioned technical solution reduces the burden on the river channel by cooperating with multiple filter grids and facilitates the cleaning of the river channel by cooperating with the first filter net and the second filter net, in the above-mentioned technical solution, the filter net is fixedly installed in the river channel body, which makes it inconvenient to clean the impurities on the filter net. After long-term use, it is easy to cause blockage, which easily affects the subsequent normal use.

[0005] To this end, we proposed a small watershed ecological restoration structure to solve the above-mentioned drawbacks. Utility Model Content

[0042] Working principle: Sewage enters the river channel body 1 through the water inlet pipe 2. By using the filter 11, impurities in urban sewage can be filtered to prevent impurities and sewage from being discharged into the river together, thereby facilitating the subsequent cleaning of the river channel. The motor 3 drives the screw 5 to rotate, and then the moving block 6 on the screw 5 is limited by the connecting block 9 and the through groove 8, so that the moving block 6 can move on the screw 5. While the moving block 6 moves, the filter 11 can be driven to move by the connecting block 9 and the connecting rod 10. When the filter 11 is removed from the river channel body 1, the filter 11 can be cleaned. The impurities on the filter 11 are cleaned to prevent impurities from remaining on the filter 11 and causing blockage, so as to facilitate its subsequent normal use. When the sewage enters the river channel body 1, it will first pass through the grille plate 14 on the water inlet pipe 2. Through the use of the grille plate 14, the sewage can be initially filtered to prevent larger impurities from entering the river channel body 1 together with the sewage. Then, through the coordinated use of the two filters 11, the filtering effect of the sewage can be further improved, and the situation where impurities and sewage are discharged together is reduced, thereby facilitating the filtering of impurities in the sewage, which is beneficial to improving the practicality of the device.
