Description
Technical field
The present invention relates to wind wave resistance elevating culture net cage system in a kind of open ocean that can assemble on the water of being made up of multiple net cage unit and reef dish on the spot, belong to aquaculture technique with the apparatus field.
Background technology
Along with the China coastal seas nature slump of disastrous proportions of fishery resources and country are to the demand of marine economy development and food, development current-resistance submerged cage is an only way of China's mariculture industry sustainable development.China greatly develops wind wave resistance net cage from " 95 ", mainly contains the circular net cage of floating HDPE at present, the various ways such as floating HDPE Square Net-cage, elevation (over-and-under) type HDPE circular net cage, metal wire casing and drift line type net cage at the wind wave resistance net cage used.The circular net cage of the elevation (over-and-under) type HDPE that current China uses adopts in float tube, is installed into drain tap and water-inflow and drain valve door, by entering (row) gas and row (entering) water in float tube, realize net cage float or sink, but due to manufacture craft relative complex, cost is higher, and the quantity applied is little.The circular net cage of the main floating HDPE of HDPE wind wave resistance net cage of present use, also have some floating HDPE Square Net-cage in addition, these net cages are generally be welded by hot-melt welding machine, and its buoyancy is provided by the HDPE pipe closed.But in China East Sea, some marine sites, south are often average annual through multiple typhoon, if adopt floating wind wave resisting net cage at typhoon through marine site, often cause net cage system to destroy, cultivation object is escaped or dead, gives to cultivate unit and bring heavy economic losses.
" 18 is large " of party proposes the strategic thought of foundation " ocean power " first.Sea fishery is one of core industry of Development of Marine economy, particularly some away from continent suitable with surrounding waters, island, aquaculture off-lying sea, reef dish in carry out cage culture, the aquatic products of high-quality can be provided for Chinese society, China's maritime rights and interests can be safeguarded again.For these regions provide the breeding facilities such as wind wave resistance net cage to be the necessary condition developing seawater cage culture, but owing to lacking electric power or land platform in these regions, wind wave resistance net cage cannot be assembled by Type of Welding, and require that net cage has and can sink when typhoon, realize the function floated after typhoon, require that net cage manufacture craft is simple, cost is not high, net cage is safeguarded and descending operation is easy.
Summary of the invention
The object of the invention is to design wind wave resistance elevating culture net cage system in a kind of open ocean that can assemble on the water of being made up of multiple net cage unit and reef dish on the spot, for away near the island, off-lying sea in continent, reef dish marine site and China coast high sea marine site provide a kind of easy to make, net cage for sea farming device that capacity of anti-storm is strong, to overcome the deficiencies in the prior art.
The present invention adopts HDPE tubing as net cage scaffold, adopts horizontal biexhaust pipe and the longitudinal double-row pipe of biexhaust pipe form, is each passed through the cavity on corner connector, is fixed by plastic rivet.Horizontal biexhaust pipe and longitudinal double-row length of tube calculate according to the hydrologic regime in sea area to be determined.According to the habit of cultivation object, by four angle connectors, the horizontal biexhaust pipe of two adjacent groups and longitudinal double-row pipe are divided into the net cage unit framework of certain specification, certain buoyancy aid and pipe connections are laid according to designing requirement in four limits.Each unit all lays the mesh bag of bottom hanging sinker, forms single fish culture net cage.The buoyancy aid of some is laid according to certain rule in the every limit of framework, buoyancy aid is designed with and fills (row) air valve and enter (row) penstock, and by buoyancy aid exhaust water inlet, realize net cage, inflatable drainage realizes net cage and floats.For ensureing the rigidity of net cage scaffold, fix with pipe connections between two tubing of every frame.Net cage scaffold by be frame rope, buoyant rope frame, buffering ball float, corkline, hawser and anchor ingot be fixed on marine site.In scaffold corner, angle ball float is housed, to cushion the effect of hawser pull to framework corner.
