to be connected with the dirt collecting component, the water accumulated in the cleaning box 29 moves into the dirt collecting component together with the sundries for temporary storage, meanwhile, the through hole component moves to the area of the filtering net 4 which is not subjected to the through hole treatment, the same through hole treatment is performed on the next area, the steps are repeated, the filtering net 4 is subjected to the comprehensive through hole 40 and the cleaning treatment from bottom to top, the smoothness of the filtering net 4 is ensured, when the cleaning component moves to the uppermost end of the filtering net 4, the upper side of the cleaning box 29 is exposed out of the water surface, and the water carrying the sundries flows out from the elbow 33, the sewage flows through the drain pipe 36 from the collecting port 35 and flows into the collecting tank 34, then the next round of cleaning operation can be carried out, and the staff can measure the time when the collecting tank 34 is fully collected, so that the sundries stored in the collecting tank 34 are treated in a centralized manner regularly, the frequency of cleaning sundries by the staff is reduced, and the workload is reduced.

To sum up, through cleaning subassembly, through-hole subassembly, collection dirty subassembly, roof subassembly and filter screen, realize intercepting the debris in the aquatic of flow hydropower station, simultaneously, automatic clear up the filter screen regularly and concentrate the function of storing the debris that clear up.
