Technical Field
The invention relates to a bottom tying net cage for underwater culture, in particular to a multi-point mooring bottom tying net cage suitable for deep and open sea culture.
Background
The development of the marine ranch is free from deep sea net cage culture equipment, and the deep sea net cage culture equipment relates to engineering problems in various aspects such as wave resistance of a net cage, convenience in bait feeding, net clothing cleaning, monitoring and operation and the like. In deep sea areas, the waves are generally large. Particularly, the east sea and the south sea of China are in typhoon-prone areas, and the influence of wind waves on the net cage culture system is particularly obvious. The development of deep sea netpen is the leading edge of the world, walked in norway, the united states and japan.
The main forms of norwegian netpen are cylindrical netpen of HDPE and sinkable tension leg netpen. The cylindrical net cage has the advantages of low cost, simple structure and convenient operation, and has the defects of high volume loss, limited operation platform area, requirement of matching with working ships and equipment and difficult operation in severe weather; the tension leg type net cage has the advantages that the structure of the box body is simple, the wind wave resistance is strong, the net cage can operate in open sea areas, the occupied area of the anchoring system is small, and when wind waves are large, the net cage can automatically sink, and the tension leg type net cage has the defects of high cost, no operating platform, difficulty in operation, complex installation of the anchoring system, and the need of matching a working ship and an underwater automatic bait casting system.
The main forms of the american netpen are butterfly netpens and spherical netpens. 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 of the net cage, high cost, incapability of effectively feeding baits due to limited area and more matched equipment required during operation; the spherical net cage has the advantages that the net is not easy to deform, the volume retention rate is high, the aluminum pipe frame structure is light and convenient, the strength is high, the shape is spherical, the volume is large, the material consumption is saved, the net cage can rotate and can realize self-flushing, and the defects that the cost is high, the frame structure is complex, the anticorrosion treatment and maintenance are needed, and the accurate operation of skilled workers is needed are overcome.
The main form of the japanese netpen is a buoyant rope netpen. The floating rope type net cage is a flexible structure and can fluctuate along with the fluctuation of wind waves, and the net cage is a box body with six closed sides and is not easy to be submerged by the wind waves to enable fishes to escape. The net cage has the advantages of low cost, simple structure of the square box body, easy manufacture, adjustable structure according to sea conditions, and weak flow resistance of the flexible rope frame, high volume loss rate, no operating platform and the need of a working ship during operation.
Deep sea aquaculture is an important industry of fishery all over the world, compared with the world aquaculture, the production mode of aquaculture in China is extensive and is influenced by the deterioration of the external water area environment and the deterioration of the internal water quality, the aquaculture space on inland and coastal near shore is extruded, and the safety problem of aquaculture products is increasingly prominent, so that the deep sea aquaculture is a necessary way for promoting the development of fishery industry in China. At present, the deepwater net cage in China has the problems of poor wind wave resistance and poor current resistance, and the novel large-scale steel structure net cage has the obstacles of high cost, large early investment and the like. Meanwhile, supporting equipment and tools of the deep and far sea netpen in China are relatively short, import is mainly relied on, and the supporting equipment and tools made in China are also in a starting stage. In addition, the southeast coastal sea area with rich culture resources in China generally has the condition of poor soil quality and has higher requirements on the mooring foundation of the net cage.
It is in this context that the present patent application proposes a multi-point mooring bottom netpen.
