Description

Multi-column type modular deep sea aquaculture net cage and installation method thereof

Technical Field

Background

In recent decades, the global aquaculture production has steadily increased and more fish and other edible aquatic organisms of commercial importance have entered various national, regional and international markets. The increasing demand for such products has stimulated the development and expansion of aquaculture production systems on land and in all bodies of water. Meanwhile, countries around the world have added requirements for ecological protection in coastal areas. The ocean fishery is gradually developing from coastal to deep open sea, however, the wide and abundant deep open sea also means that a fishery is in a severe ocean environment, and the design of the aquaculture net cage needs to design a net cage structure which can have certain safety under the condition of severe sea conditions under the condition of saving resources and cost as much as possible.

By combining the net cage structure and the platform structure, the fishery breeding platform can be divided into a flexible breeding equipment system and a rigid breeding equipment system.

In the prior art, most of the used flexible net cages can be classified as gravity type net cages. Existing gravity-type net cages typically include a surface ring structure as a cage, a net suspended in a water column, and a weight suspended from the bottom of the cage to maintain the shape of the cage. Of these, HDPE cages are the most widely used gravity cages. HDPE is compliant with waves, i.e., it bends with passing waves, rather than remaining rigid. The flexible net cage has the defects that the flexible net cage is easy to deform under the action of wave current, and the culture water body is easy to lose.

Rigid farming equipment is typically made from large steel structures, mostly comprising semi-submersible structures with pontoons and struts, in order to be structurally strong enough to resist the wave action. The large-scale frame type net cage structure is characterized in that the net is supported into a fixed shape by the upright posts and the cross braces, and meanwhile, the net has pretension, so that the effective culture volume is basically kept unchanged. But the rigid breeding equipment has larger steel quantity and higher manufacturing cost.

The invention is suitable for deep sea culture and is convenient for expanding the culture capacity. The mooring system can be arranged in a sea area with deeper water depth by adopting a mode that the suction pile anchor 40 is used for positioning the vertical column body 1, so that the deep sea culture is a real deep sea culture. The mooring system of a single net cage module only has three vertical mooring cables 4 with pretension, so that the mooring system is convenient for the operation of berthing of a working ship, reduces the complexity of the mooring system and has economical efficiency. When the cultivation equipment is modularly expanded, the cultivation capacity can be expanded only by adding a group of upright columns 1 and relying on the original cultivation equipment.

The net cage module in the invention adopts a vertical tensioning type mooring mode, occupies a smaller area, does not extend transversely, reduces the risk of collision with passing ships, and is convenient for mooring operation ships.

Certainly, the vertical axis fan can be arranged at the top of the vertical column body 1, and a vertical axis fan array is formed after the plurality of net cage modules are arranged, so that the aerodynamic performance of a wind field is improved, and the self-powered energy supply can be realized for the operation of the net cage modules, and the vertical axis fan array is used for mechanical equipment.

The net cage module has higher rigidity as a whole, effectively eliminates most vertical motion, rolling motion and pitching motion of the culture equipment, and greatly ensures effective culture water on the basis of resource conservation.

The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
