Description

Net cage system

Technical Field

The invention relates to the field of ocean engineering structures, in particular to a net cage system.

Background

The open sea net cage is a mariculture mode with higher technological content at present. The open sea net cage has the characteristics of strong wind and wave resistance, capability of culturing marine products in a semi-open sea area and the like, so that compared with the traditional small net cage, the open sea net cage has the advantages of high intensification degree and high culture density, the food sources of fish cultured in the net cage are more abundant, the fish grows at a high speed, the meat quality is good, and the quality is natural. Meanwhile, the seawater has a certain flow velocity, and the excrement of the fishes and the marine products can be quickly taken away by the seawater, so that compared with the traditional net cage, the open sea net cage has fewer diseases in cultivation. The advantages make the quality of the aquaculture products of the open sea net cage superior and the economic benefit of aquaculture obvious.

In deep sea areas, the stormy waves are generally large, and the influence of the stormy waves on cage culture in open sea is particularly obvious. To ensure the safety of the cultured marine products, the open sea cages must have reliable wind and wave resistance. The wind and wave resistance of the net cage can be influenced by the box body structure and the base component of the net cage to a great extent.

The existing open sea large-scale seat bottom net cage generally adopts a portal steel frame structure, and simultaneously adopts an independent hollow steel mat as a base. Such cages have the following drawbacks: 1. the portal frame structure bears load through bending of the beam column section, and if a large-span portal frame is used, a beam column with a large section needs to be used, so that the steel consumption is increased; 2. the steel beam-pillar-caisson-periphery anti-collision system which is completely made of a steel frame structure has huge steel consumption and high cost; 3. a pure steel component is used as a force bearing system, and the pure steel component is welded by a welding process which has complex requirements on the connection strength and the metal fatigue property; 4. when the net cage is assembled, a large amount of welding work is needed, the complicated welding process and a large amount of checking work cause long occupied field, the requirement of high-grade welders is high, and the installation cost is high; 5. the independent hollow steel mat is used as a base, so that the edge of the base is easily eroded by water flow, and meanwhile, the natural removal of dirt under the net cage by the bottom flow is prevented; 6. because water is injected into the sinking pad to sink, the inside and the outside of the steel structure of the sinking pad need to be subjected to anticorrosive treatment, and the usage amount of the anticorrosive paint is increased; 7. the whole gravity center of the net cage system with the portal steel frame structure is higher, so that the in-place stability of the net cage system is poor.
