[0038] In a specific application scenario, the silt impurities carried by the flowing water are filtered out by the filter plate piece 15 and accumulated on the inclined filter plate piece 15, the water falls after being filtered by the filter plate piece 15 and impacts the impact impeller two 902, the impact impeller two 902 rotates to drive the connecting rod piece 904 to rotate, forcing the pushing rod piece 905 to reciprocally push the connecting frame 906, driving the pushing rod 907 to reciprocally push, pushing the silt impurities accumulated on the filter plate piece 15 into the collecting box 10, avoiding the filter plate piece 15 from being blocked; it can be real-time self-cleaning and anti-blocking, by driving the pushing mechanism to reciprocally push the silt impurities, continuously removing the deposited silt during the water collecting process, avoiding the drainage efficiency from being attenuated due to the filter plate piece 15 being blocked, and ensuring the system to continuously and efficiently operate.

[0039] Working principle: when heavy rain and other weather conditions occur, the water in the mine pit is not treated, and a large amount of surface water is drained through the drainage and permeation layer 4, and the water flows through the filter frame 12 and the semi-permeable membrane 13 into the main communication pipe 6, the greater the water flow, the greater the impact on the impact impeller 803, the impact impeller 803 is impacted by the water flow and slides outside the rotating rod 802, the impact impeller 803 drives the movable ring 806 to compress the return spring 807, so that the locking tooth piece one 804 and the locking tooth piece two 808 are engaged and locked, and then the impact impeller 803 rotates to drive the rotating rod 802 to rotate, at this time, the extension spring 812 pushes the sliding piece 810 outward, so that the ball 811 is located in the clamping groove on the connecting ring 818, the rotating rod 802 drives the movable cylinder 817 to overcome the elastic action of the coil spring 816 through the connecting seat 809 and the connecting ring 818, and the winding wheel 819 rotates with the movable cylinder 817, the pulling rope 820 is tightened, the pulling rope 820 is pulled along the guide pipe 821 to overcome the elastic action of the torsion spring 824 to open the switch cover plate 825, the surface water can flow down through the collection vertical pipe 7, and the water is quickly drained to avoid excessive water that cannot be treated. When the switch cover plate 825 is opened to the limit position, the pulling rope 820 is fixed so that the movable cylinder 817 cannot continue to rotate, and the rotating rod 802 and the connecting seat 809 continue to rotate relative to each other, forcing the ball 811 to compress the extension spring 812 and disengage from the clamping groove, and the connecting seat 809 cannot drive the movable cylinder 817 to rotate.
