The marine aquaculture device based on an offshore wind farm according to claim 2, characterized in that: The ecological feeding mechanism (5) includes a shellfish box (501), and the shellfish box (501) is fixedly installed at the lower end of the ocean platform (1). Coral reefs are stored in the inner wall of the shellfish box (501). A collecting ring (502) is rotatably installed at the lower end of the aquaculture net cage (201). The lower end of the collecting ring (502) is rotatably connected to a guide net tube (503), and the end of the guide net tube (503) away from the collecting ring (502) is fixedly installed at the side end of the shellfish box (501).

4. A method for aquaculture of an offshore wind farm-based marine aquaculture device, used for an offshore wind farm-based marine aquaculture device according to any one of claims 1 to 3, characterized in that: The following steps are involved: S1: Controlling the motor (408) to cause the valve stem (407) to drive the valve plate (406) to start rotating, so that the discharge valve (402) is closed, the valve stem (407) rotates to drive the linkage rope (410) to move, the linkage rope (410) drives the rotating rod (412) to start rotating, so that the rotating rod (412) drives the blocking plate (411) to start rotating, thereby opening the discharge valve (404), so that the fish feed in the storage pipe (403) is discharged into the aquaculture cage (201) through the discharge pipe (405), so that the marine aquaculture device can feed the fish at a fixed point through the ocean tide; S2: When the ocean tide rises and the sea level rises, the water level in the water level pipe (413) begins to rise, the floating ring (414) begins to move upward, the power block (418) and the brush block (424) are separated, the control motor (408) is turned off, the winding spring (409) closes the discharge valve (404), and the discharge valve (402) is opened, so that the fish feed begins to be stored in the storage pipe (403), so that the marine aquaculture device can feed the fish in a fixed amount.
