Curtain type manual down-flow device combined with fish reefs

The invention discloses a curtain type manual down-flow device combined with fish reefs, and belongs to the technical field of ocean anoxia solving; the curtain type manual down-flow device comprisesfloating balls, ropes, curtain cloth, a steel fixing frame, artificial reefs and anchoring structures, wherein the floating balls are connected with the steel fixing frame through the ropes, the curtain cloth is fitted on the steel fixing frame, reinforcing ribs penetrate the steel fixing frame, and the artificial reefs are connected to the bottom of the steel fixing frame and fixed on the seabedthrough the anchoring structures. When oxygen-enriched water entrained by tidal currents flows through the device, a down-flow is generated under the induction of the inclined curtain cloth and is discharged after being mixed by the artificial reefs at the bottom of the device, and the discharged oxygen-enriched water is mixed with surrounding anoxic water so as to alleviate the anoxia problem ofthe seabed. 本发明公开了一种结合鱼礁的幕布
