Abstract

The invention discloses a semi-submersible type aquaculture net cage cluster system, and belongs to the technical field of mariculture. According to the semi-submersible type aquaculture net cage cluster system, a needed vertical force is provided by nine evenly-distributed anchoring floats, and each anchoring float is fixed to the bottom of the sea through a vertical anchor chain; the semi-submersible type aquaculture net cage cluster system is fixed to the bottom of the sea through 12 evenly-distributed vertical anchor chains, and each circular aquaculture net cage is connected with four adjacent anchoring floats through four fixing anchor chains, and the bottom of each circular aquaculture net cage is connected with a plurality of vertical anchor chains with weight blocks, so as to restrict motion of each circular aquaculture net cage under the action of ocean currents and fish schools; the upper portion of each circular aquaculture net cage is provided with a frame float, the lower portion of each circular aquaculture net cage is provided with a ballast tank, and a floating position of each circular aquaculture net cage in water can be controlled through adjusting the corresponding ballast tank. The floating position of each aquaculture net cage is controlled through the corresponding circular ballast tank at the bottom of each aquaculture net cage; when at a ballast state, the aquaculture net cage sinks at a certain distance under the water so that deformation of the aquaculture net cage due to loads of waves and the ocean currents is significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of sea farming and relates to a semi-submersible farming cage cluster system. Background technique [0002] The development of marine aquaculture to deep water puts forward higher requirements on the ability of aquaculture cages to resist wave and current loads. Traditional floating culture cages are prone to large deformation under the action of strong waves and currents, resulting in a significant reduction in effective volume. The effect of waves and ocean currents on the semi-submersible net cages installed below a certain water depth will be greatly reduced, so the deformation of the net cages is also small. However, since this kind of net cage mostly adopts a rigid structure, the construction cost is generally higher, and the fishing and feeding operations are also more complicated. Research on aquaculture cage clusters with good economic performance, easy scale promotion, and high environmental load...
