When the sewage of the urban road completely flows into the device through the inspection well, the reclaimed water in the other reclaimed water treatment station reversely flows into the reclaimed water treatment station, the rotary blade 43 drives the transmission straight rod 42 to reversely rotate through the water flow difference in the driving cylinder 40, and the transmission straight rod 42 is attached to the ratchet teeth 52 of the limiting cylinder 48 of the side wall of the transmission pulley 44 through the right angle edge of the limiting inclined block 50, so that the transmission straight rod 42 drives the transmission straight rod 38 to rotate through the transmission belt 45 and the transmission pulley 44. The transmission straight rod 38 drives the limit lantern ring 34 to rotate through the meshing relationship of the driving gear 39 and the annular gear 37, the limit lantern ring 34 drives the three spiral curved rods 35 to synchronously rotate, the three spiral curved rods 35 can transport sediment between the inner side wall of the hollow cylinder 12 and the outer side wall of the filter screen cylinder 22 into the drainage sleeve 15, and the inner side wall of the hollow cylinder 12 and the surface of the filter screen cylinder 22 can be cleaned through the cylinder bristles 36 on the surface of the spiral curved rods 35.

At this time, the end inclined plane of the limiting inclined block 50 of the transmission straight rod 42 is attached to the inclined plane of the ratchet 52 of the limiting cylinder 48 on the periphery of the rotation straight rod 25, so that the transmission straight rod 42 cannot drive the rotation straight rod 25 to rotate.
