Description
Technical field
The utility model relates to a kind of beformable body deep water mesh cage, has certain opposing stormy waves performance, belongs to seawater cage culture field.
Background technology
There is high investment, high risk notable feature in mariculture, but because of the advantage of its high efficiency, high repayment be day by day the extensive use of large-scale cultivation activity institute.Deep water mesh cage technology develops rapidly over nearly twenty or thirty year, especially very wide in east China and Southern Coast one band application.Deep-water net cage culture, its risk mainly comes from the loss that large-scale stormy waves causes.
The applied deep water mesh cage of China at present, the state with it in water can be divided into floating, the formula of diving and elevation (over-and-under) type; With net cage casing building mode can be divided into gravity type, anchoring tension type, from tension force or self-support type net cage.Various net cages are all application to some extent in China different regions, but are all faced with the problem of wind wave resistance performance deficiency, thereby in application, are also only suitable for the marine site that stormy waves is less.Mariculture focuses mostly in the waters, bay and semi-closed bay of offshore, and water body leaves standstill and to exchange the less water quality that causes poor; Region is limited forces again raiser to strengthen cultivation density, has accelerated water quality deterioration on the one hand, also affects on the other hand product quality and efficiency.Along with the development of marine product industry in recent years, immediate offshore area can not meet mariculture industry development need.
Mariculture industry is to off-lying sea and profundal zone expansion, and the wind wave resistance performance of net cage is major issue first to be solved.
Summary of the invention
The purpose of this utility model is to provide a kind of deep-water netted case resisting wind and wave of flexible structure, it is simple in structure, easy for installation, cost reasonable and have stronger capacity of anti-storm, can be effectively under certain stormy waves condition by the generation deformation of taking advantage of a situation of self flexible structure, reduce the direct stress of stormy waves to net cage, impact harm thereby effectively resist stormy waves.
The deep-water netted case resisting wind and wave of flexible structure described in the utility model, comprising: floating on the framework of the water surface, is the rectangular frame that adopts two hawsers to surround through four angles; The glass fibre reinforced plastic cylinder of Armrest is equipped with to maintain the shape of rectangle in four angles of described framework; The four edges of described framework is respectively arranged with multiple sealing plastics keg floats, with a determining deviation arranged in series; Described keg float is limited between described two hawsers; And longitudinal section is the etting of chamfered edge vertebra shape, the upper end open of described etting is fixed on described framework, and the shape of opening is consistent with the shape of described framework; The lower end of described etting is closed rectangular, and its four angles hang with sinker.
According to the further feature of the deep-water netted case resisting wind and wave of flexible structure described in the utility model, there are respectively upper and lower two bar iron lines the upper end of described etting, and exaggerated line is fixed on described handrail, and infraclass line is fixed on described hawser.
According to the further feature of the deep-water netted case resisting wind and wave of flexible structure described in the utility model, described glass fibre reinforced plastic cylinder is to be formed in parallel by inside and outside two quarter bend cylinders, ties up each other fixing with bonding jumper.
According to the further feature of the deep-water netted case resisting wind and wave of flexible structure described in the utility model, the turn of bilge of described glass fibre reinforced plastic cylinder is stretching outside four angles and be anchored to seabed respectively by rope and anchor, to cause net cage body to maintain expansion state.
According to the further feature of the deep-water netted case resisting wind and wave of flexible structure described in the utility model, some polystyrene plastics foam blocks also can be set between described keg float.
The deep-water netted case resisting wind and wave of flexible structure described in the utility model has following design feature:
(1) this deep water mesh cage main body comprises above water and underwater portion, waterbornely mainly comprise the mounting system being made up of the glass fibre reinforced plastic cylinder of Armrest and the buoyancy system being made up of hawser, keg float, underwater portion is mainly etting and maintains the fixed system that expansion hangs and form.
(2) buoyancy system is mainly that net cage upper end is floated on the water surface, is mainly made up of keg float and hawser.By sealing keg float arranged in series, for example, between bucket, interval is about 1m, also can carry out spacing adjusting according to required buoyancy size, or suitably supplements use polystyrene plastics foam block.The both sides of keg float fasten fixing by hawser.Hawser be by inside and outside two side by side, entirety form rectangle.The visual net cage size of rectangular aspect ratio example is carried out flexible design voluntarily.
(3) mounting system is mainly that dimension net cage keeps certain shape and complying with point for the suspension of etting provides, and is mainly the cylindric L shaped platform of glass steel material, is positioned at net rectangle net cage corner location, and top is fixed with handrail, between handrail, is mutually connected with hawser.In four jiaos, rectangle, form rectangle support by hard glass steel cylinder, in order to maintain net cage rectangle, and supporting platform while safeguarding for net cage.Glass fibre reinforced plastic cylinder top is with handrail, in order to hang etting.
(4) etting is the main body of net cage, and entirety presents contracting shape chamfered edge vertebra shape from top to bottom; On the water surface, part has respectively upper and lower two horizontal guiding principle lines, exaggerated line to hang between mounting system handrail and handrail on hawser, and infraclass line hangs on the hawser of buoyancy system.Etting presents contraction-like chamfered edge vertebra shape from top to bottom under water, can reduce like this influence that under sea, water body flow causes to mounting system by etting.
(5) fixed system maintains relative position and is not subjected to displacement for fixed cage, and maintains casing expansion, makes space keep maximum; Mainly comprise by four jiaos of hawsers along angle out-draw of rectangle net cage and anchor, and the sinker of net cage bottom hanging, for fixing whole net cage anchor and hawser respectively from four jiaos of glass fibre reinforced plastic cylinders along four angle out-draws.
Compared with traditional net cage technique, the deep-water netted case resisting wind and wave of flexible structure described in the utility model has following remarkable result:
(1) adopt sealing keg float, there is better buoyancy effects compared with conventional plastic tubular construction, can carry out the fluctuation within the scope of certain amplitude with stormy waves, impact thereby reduce stormy waves strength.
(2) adopt hawser, keg float structure, more traditional all-plastic or glass fibre reinforced plastic structure cost are cheaper, can effectively reduce aquaculture cost.
(3) etting body presents contraction-like chamfered edge vertebra shape from top to bottom, and when this structure can reduce water body flow, the direct resistance of etting body and the influence that boat support frame system is caused, contribute to maintain net cage monolithic stability.
(4) can there is certain deformation with stormy waves in the beformable body structure being formed by hawser, thereby reduce the direct stress of stormy waves, effectively resists stormy waves and attack.
