When the non-water-break phase, fixed link (44) is arranged in the fixing groove (42) being located above, at this time the water blocking in sliding slot (43)
Plate (41) upward sliding, and water-retaining structure is formed with ecological purification device；Due to the barrier of water fender (41), farmland water-break can not
It being expelled directly out from gutter, water flow can be flowed into ecological purification device by the water inlet of the settling zone (31) of ecological purification device, and
Settling zone (31), absorption retention area (32), ecological purification area (33) are flowed successively through, purified tail water will pass through ecological purification area
(33) discharge outlet at is discharged into farmland drainage ditch again, completes the purification of water quality process of farmland water-break.
