in the process that the first filter plate (33) moves downwards, when the first filter plate (33) reaches the first sludge discharge port (312), the first baffle resetting piece (7) can be gradually stirred to open the first sludge discharge port (312), meanwhile, the second filter plate (34) can gradually leave the second sludge discharge port (313), the second baffle resetting piece (8) can gradually block the second sludge discharge port (313), meanwhile, in the transient process that the guide fan-shaped cylinder (35) rotates to pass through the drainage channel (2), part of rainwater in the drainage channel (2) can enter the interior of the guide fan-shaped cylinder (35) through the third filter plate (36), and then enter the annular filtering inner cylinder (32) from the bottom end of the guide fan-shaped cylinder (35), and a water source can be provided for the first water spraying assembly (37) and the second water spraying assembly (38);
when the first filter plate (33) gradually pulls the first baffle reset piece (7) to enable the first sludge discharge port (312) to be gradually opened, the first water spraying assembly (37) is controlled to spray water, and then water can be reversely sprayed to the bottom surface of the first filter plate (33), at the moment, the first filter plate (33) gradually inclines, and through the action of gravity and the cooperation of the reverse water spraying of the first water spraying assembly (37), impurities accumulated on the first filter plate (33) can be poured into the first sludge discharge port (312), so that the automatic cleaning of the impurities on the first filter plate (33) is realized;
similarly, after the second filter plate (34) keeps a horizontal state to filter rainwater, impurities on the second filter plate (34) can be gradually increased, the weight above the second filter plate (34) is gradually increased, the second filter plate (34) can be gradually rotated and moved downwards, and meanwhile, the first filter plate (33) is gradually driven to rotate upwards, so that the guide fan-shaped cylinder (35) is driven to rotate to the position of the initial state again and finally abut against the limiting block (6);
when the second filter plate (34) rotates and moves downwards, the second baffle resetting piece (8) can be gradually stirred to open the second sludge discharge port (313), meanwhile, the first filter plate (33) can gradually leave the first sludge discharge port (312), the first baffle resetting piece (7) can gradually block the first sludge discharge port (312), meanwhile, in the transient process that the guide fan-shaped cylinder (35) rotates and passes through the drainage channel (2), part of rainwater in the drainage channel (2) can enter the guide fan-shaped cylinder (35) through the third filter plate (36), and then enters the annular filtering inner cylinder (32) from the bottom end of the guide fan-shaped cylinder (35), and a water source can be provided for the first water spraying assembly (37) and the second water spraying assembly (38);
when the second filter plate (34) gradually stirs the second baffle reset piece (8) to enable the second sludge discharge port (313) to be gradually opened, the second water spraying assembly (38) is controlled to spray water, and then water can be reversely sprayed to the bottom surface of the second filter plate (34), at the moment, the second filter plate (34) gradually inclines, and through the action of gravity and the cooperation of the reverse water spraying of the second water spraying assembly (38), impurities accumulated on the second filter plate (34) can be poured into the second sludge discharge port (313), so that the automatic cleaning of the impurities on the second filter plate (34) is realized;
filterable impurity on third filter (36), rotate gradually to the in-process that leaves sewage passageway (2) in third filter (36), can be scraped to annular filter urceolus (31) by the edge of sewage passageway (2), can drop respectively to first filter (33) or second filter (34), and then follow-up mud mouth (312) or the discharge of second mud mouth (313) of following-up row, realize the automatic clearance to impurity on third filter (36).
