Description

An offshore wind and wave cage

technical field

The present invention relates to the technical field of marine engineering equipment, and more particularly, to a marine anti-wind and wave cage.

Background technique

Due to the shortage of offshore cage culture space year by year, and the slow flow of water in shallow sea areas and the low degree of seawater exchange, which are not conducive to fish cultivation and growth, deep-sea cages gradually replaced offshore cages and became the mainstream of offshore cage culture. Deep-sea cages solve the problems of harsh water quality and excessive breeding density in offshore cages, and are generally used in sea areas with water depths greater than 20 meters. The advantages of deep-sea cages are: (1) to improve the living water quality environment of fish, deep-sea cages avoid the offshore waters occupied by real estate and tourism development, and the water pollution in the far sea is relatively less, and fish feces and other substances are diluted , the water body can be exchanged freely; (2) the scale benefit increases, due to the reduction of space constraints, the scale of aquaculture can be doubled, thus producing huge benefits; (3) the structural system is more superior, compared with offshore cages, deep-sea cages have increased The automatic feeding system, lifting system, wave power generation system and other facilities make the functions of the cage more complete, which is convenient for fishermen and reduces labor costs.

In my country, the East China Sea and the South China Sea are in the typhoon-prone areas, and the wind and waves are relatively large, especially during the typhoon period. In 2011, a strong typhoon hit Hainan, and the local marine aquaculture industry was devastated. About 70% of the affected deep-water cages were damaged by the mooring system, and about 30% were damaged by the main structure of the cages. Many cages were damaged by broken anchor chains and caused great economic losses. Therefore, the mooring device must have reliable wind and wave resistance. At present, the wind and wave resistance of cages is divided into two types: active and passive. Active wave resistance relies on the strength of the main structure and the anchor structure to resist part of the wind and waves, and mainly relies on diving when the wind and waves are too large to avoid the frontal impact of the wind and waves. Passive wave resistance is to use the strength of the main structure and the anchor structure to resist wind and waves. However, the active anti-wave method has a complex structure and can only be used in the deep sea area. When diving, it may cause the cage to overturn and damage the fish and seafood. Passive anti-wave only increases the strength of the main structure and the anchor structure. The cost is relatively high. High, the anti-wind and wave effect is not good.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a marine anti-wind and wave cage suitable for deep sea areas and strong wind and wave areas. The principle of "energy absorption and energy consumption" is adopted to improve the safety performance of the deep-sea cage and improve the Its resistance to huge wind and waves can effectively resist the damage of strong wind and waves to the cage.
