Device for regulating and repairing aquaculture ecological environments

The utility model discloses a device for regulating and repairing aquaculture ecological environments. The device comprises a stand and water tilling boards, the number of the water tilling boards is three, and the water tilling boards are connected with and the stand through connection rods respectively; a plurality of through holes and protrusions are arranged on the water tilling boards, auxiliary boards are arranged on lower end faces of the water tilling boards and can stretch selectively at two ends of the lower end faces of the water tilling boards, and the auxiliary boards and the lower end faces of the water tilling boards form inclined end faces with different included angles. The device has the advantages that frictional resistance between the water tilling boards and water bodies can be reduced effectively during rotation, the re-oxygenation efficiency of water bodies are increased simultaneously, and accordingly, dissolution oxygen contents in the water bodies are increased; optimal dynamic condi
