sinking bin is reduced, thereby reducing the downward pulling force of the cage body from the
water storage sinking bin to realize the floating of the culture cage. Therefore, the present
invention realizes the gravity redistribution by the inner circulation between the water storage
floating bin and the water storage sinking bin to adjust the height of the culture cage in water,
and the fresh water has less corrosion damage to the equipment, avoiding the problem that the
water in the external environment enters into the lifting adjustment device for a long time,

1 can smoothly flow into the water storage sinking bin 2.
[0033] When the lifting adjustment device for culture cage is used to adjust the sinking of
the gravity type culture cage: the submersible pump 7 is closed, the solenoid valve 6 is
opened, and the fresh water inside the water storage floating bin 1 flows into the water storage
sinking bin 2 by self weight thereof, and the gravity of the water storage sinking bin 2

environment enters the lifting adjustment device for a long time, which will lead to the poor
water inflow and drainage, and ensures the long-term reliability of the lifting adjustment of the
culture cage. In addition, through remote control, it can improve the timeliness and
convenience of lifting control for the gravity type culture cage in long distance and in open
seas.
