In this embodiment, three spray pipes 44 are provided and are arranged around the rotating pipe 43 at intervals in the circumferential direction; the spout is arranged in a rectangular shape with the longer side of the rectangular shape being parallel to the axis of the rotating tube 43.
When the submersible pump works, high-pressure water is continuously output from the water outlet 21, and at the moment, part of the high-pressure water periodically flushes each filter hole 11 through the dredging device 4, so that the probability that each filter hole 11 is blocked by waterweeds is effectively reduced.
Referring to fig. 4 and 5, a speed governor 5 is further provided between the rotating tube 43 and the bracket 3. When the blockage does not occur, the rotating speed of the rotating pipe 43 is higher so as to shorten the interval time for flushing each filter hole 11; when a part of the filter holes 11 are blocked, the rotating speed of the rotating pipe 43 is reduced to increase the time for flushing the single filter hole 11, so that impurities are flushed away by water flow to dredge the single filter hole 11.
