Background
The development of the marine pasture is not separated from the deep sea net cage cultivation equipment, and the deep sea net cage cultivation equipment relates to engineering problems in various aspects such as the wave resistance of the net cage, bait feeding, net clothes cleaning, monitoring and operation convenience. In deep water sea areas, stormy waves are generally large. Especially, the east and south China sea are in typhoon frequent areas, and the influence of wind waves on the net cage culture system is particularly obvious. The development of deep sea nettings is norway, united states, japan, leading in the world.
The main form of the Norway net cage is a cylindrical net cage made of HDPE material and a tension leg net cage which can sink. The cylindrical net cage has the advantages of low cost, simple structure and convenient operation, and has the defects of higher volume loss, limited operation platform area, need of matched working ships and equipment and difficult operation in severe weather; the tension leg type net cage has the advantages that the box body is simple in structure and strong in wind wave resistance, can be operated in open sea areas, and can automatically sink when the ground occupied area of an anchoring system is small and the wind wave is large, and has the defects of high cost, no operation platform, difficult operation, complex installation of the anchoring system, and the need of matching a working ship with an underwater automatic bait casting system.
The main form of the U.S. netpen is a butterfly netpen and a spherical netpen. The butterfly net cage has the advantages of good integrity, high volume retention rate, strong wind and wave resistance, simple anchoring, convenient dragging and moving, high cost, limited area and less effective bait feeding, and needs more matched equipment during operation; the spherical net cage has the advantages of difficult deformation of the net, high volume retention rate, light aluminum pipe frame structure, high strength, spherical shape, large volume, material saving, rotatable net cage, self-flushing realization, and the defects of higher cost, complex frame structure, corrosion prevention treatment and maintenance, and correct operation of skilled workers.
The main form of the Japanese netpen is a floating rope netpen. The floating rope type net cage is composed of ropes, a box body, floats, iron anchors and the like, is a flexible structure, can undulate along with the fluctuation of wind waves, is a six-face closed box body and is not easy to be submerged by the wind waves so that fishes can escape. The net cage has the advantages of low cost, simple square box structure, easy manufacture and adjustable structure according to sea conditions, and has the defects of weak flow resistance of the flexible rope frame, high volume loss rate, no operation platform and the need of matching with a working ship during operation.
The deep sea aquaculture is an important industry of fishery worldwide, compared with the world aquaculture large country, the aquaculture production mode of China is extensive, the aquaculture production mode is influenced by the environmental deterioration of external water areas and the internal water quality deterioration, the aquaculture space of inland coastal coasts is extruded, and the safety problem of aquaculture products is increasingly outstanding, so the deep and open sea is a necessary path for promoting the development of fishery industry of China. At present, the deep water net cage in China has the problems of poor wind wave resistance and current resistance, and the novel large steel structure net cage has the problems of high cost, large investment in the early stage and the like. Meanwhile, the matched equipment and tools of the deep-open sea net cage in China are relatively lacking, and mainly depend on import, and the matched equipment and tools in China are also in a starting stage. In addition, in the southeast coastal area with rich culture resources in China, the condition of poor soil quality generally exists, and the requirement on the mooring foundation of the net cage is high.
It is against this background that the present patent application proposes a multipoint mooring system bottom net cage.
