Description
Technical field
The present invention relates to wind wave resistance elevating culture net cage system in a kind of marine site, off-lying sea that can assemble on the water being formed by multiple net cages unit and reef dish on the spot, belong to aquaculture technique with the apparatus field.
Background technology
Along with slump of disastrous proportions and the country demand to marine economy development and food of China coastal seas nature fishery resources, development deep water wind wave resistance net cage is an only way of China's mariculture industry sustainable development.China starts to greatly develop wind wave resistance net cage from " 95 ", mainly contains the circular net cage of floating HDPE at present at the wind wave resistance net cage using, the various ways such as floating HDPE Square Net-cage, the circular net cage of elevation (over-and-under) type HDPE, metal wire casing and drift line type net cage.The circular net cage of elevation (over-and-under) type HDPE that China is used at present adopts and 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 floating or sink, but due to manufacture craft relative complex, cost is higher, and the quantity of applying is little.The circular net cage of the main floating HDPE of HDPE wind wave resistance net cage using now, also has some floating HDPE Square Net-cage in addition, and these net cages are to be generally welded by hot-melt welding machine, and its buoyancy is provided by the HDPE pipe sealing.But in China East Sea, some marine sites, south are every average annual through multiple typhoons, if adopt floating wind wave resisting net cage at typhoon through marine site, tend to cause net cage system to destroy, cultivation object is escaped or is dead, brings heavy economic losses to cultivation unit.
" 18 is large " of party proposed the strategic thought of foundation " ocean power " first.Sea fishery is one of core industry of Development of Marine economy, particularly in suitable and surrounding waters, island, aquaculture off-lying sea, reef dish, carry out cage culture away from continent at some, the aquatic products of high-quality can be provided for Chinese society, can safeguard again China's maritime rights and interests.The necessary condition of development seawater cage culture for these regions provide the breeding facilities such as wind wave resistance net cage, but owing to lacking electric power or land platform in these regions, cannot assemble wind wave resistance net cage by Type of Welding, and require net cage to have in the time of typhoon to sink, typhoon is realized later the function of floating, requires 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 marine site, off-lying sea that can assemble on the water being formed by multiple net cages unit and reef dish on the spot, for near the island, off-lying sea away from 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, through the cavity on corner connector, fixes by plastic rivet respectively.Laterally biexhaust pipe and longitudinal double-row length of tube are according to the hydrologic regime calculative determination in sea area.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.The mesh bag of bottom hanging sinker is all laid in each unit, forms single fish culture net cage.The buoyancy aid of some is laid on the every limit of framework according to certain rule, be designed with and fill (row) air valve and enter (row) penstock on buoyancy aid, by buoyancy aid exhaust water inlet, realizes net cage, and inflatable drainage is realized net cage floating.For ensureing the rigidity of net cage scaffold, between two tubing of every frame, fix with pipe connections.Net cage scaffold is by being that frame rope, buoyant rope frame, buffering ball float, corkline, hawser and anchor ingot are fixed on marine site.Four jiaos of scaffolds, angle ball float is housed, to cushion the effect of hawser pull to four jiaos of frameworks.

Open charge, exhaust valve (17) and drainage valve (20), make to be full of air in buoyancy aid (5) by inflation, then close charge, exhaust valve (17) and drainage valve (20) is closed, make net cage scaffold float on the water surface, and the drainage valve (20) of flexible pipe (19) one end is placed on the water surface; In the time that net cage need to sink, open charge, exhaust valve (17) and drainage valve (20), drainage valve (20) is thrown away in water, the exhaust of intaking in buoyancy aid like this, net cage, under the effect of heavy power, is realized; In the time that net cage need to float, charge, exhaust valve (17) is connected with air pump by gas tube, to injecting gas in buoyancy aid, water in buoyancy aid is by entering, arranging) penstock (20) eliminating, net cage is under the buoyancy of buoyancy aid (5), realize floating, after floating, close two valves, can ensure that net cage floats on the water surface.
