Description
Technical field
The present invention relates to oceanic pasture dykes and dams or large-scale culturing net and enclose the large-scale netting gear processing method in field of engineering technology.
Background technology
Oceanic pasture dykes and dams or large-scale culturing net enclose concept and technology contents between netting gear in field of engineering technology and fishing gear, fish culture net cage and differ greatly, and fishing gear field etting processing method, fish culture net cage technical field casing etting processing method are not all suitable for oceanic pasture dykes and dams or large-scale culturing net encloses the double-deck large-scale netting gear etting processing method in field of engineering technology.Because aquaculture mode and stocked carp specification are different, etting size of mesh difference is larger; According to the size of size of mesh, the etting that people are not more than 50mm by size of mesh is called little mesh net or little mesh etting (if little mesh polyethylene is through netting), and the etting that size of mesh is not less than 200mm is called to large mesh net or large mesh etting (if large mesh polyethylene is through netting).According to the number of plies of etting in netting gear, people are called single layer fibre net or single layer fibre etting by single layer structure synthetic fibers etting, just double-decker synthetic fibers etting is called double-deck fleece or double-deck fiber etting, and three-decker synthetic fibers etting is called to three layers of fleece or three layers of fiber etting etc.The online marine biofouling of existing netting gear single layer fibre is serious, single layer fibre net is directly connected wearing and tearing with stanchion, under the bad weathers such as typhoon, hurricane tide, can there is the bad fish race accident of net in single layer fibre net, this brings loss not only to raiser or breeding enterprise, and the cultured fishes of escaping in a large number also can destroy local sea area biological chain sometimes, thereby bring heavy losses to whole industry and even marine ecology.In existing netting gear, put average weight in a suitable place to breed while being four double large yellow Crocker, people can adopt the single layer fibre net of size of mesh 65mm, once stocked carp difference in size is larger, small dimension fish in the stocked carp cultivation accident of escaping from single layer fibre net mesh will occur.Some technical barriers urgently to be resolved hurrily in netting gear evolution, have been exposed at present, marine biofouling problem as anti-in netting gear etting, between netting gear etting and stanchion (custom is referred to as between net stake) be directly connected contact wear problem, the not smooth problem of the inside and outside water body exchange of netting gear etting, the interior stocked carp escape problem of netting gear etting etc., the potential threat of the problems referred to above is large, had a strong impact on the culture benefit that oceanic pasture or large-scale culturing net enclose, therefore, it is the art unsolved technical barrier still for a long time that oceanic pasture dykes and dams or large-scale culturing net enclose double-deck large-scale netting gear etting processing method in field of engineering technology.The art is in the urgent need to a kind of double-deck large-scale netting gear etting processing method, to prevent stocked carp, escape, avoid directly connection contact wear between net stake, reduce draping number of times or labour intensity, raising cultivation comprehensive benefit, improve etting antifouling property and shock resistance, the Sustainable Healthy Development that boosting oceanic pasture or large-scale culturing net culture in enclosure are grown.
Summary of the invention
The invention provides a kind of double-deck large-scale netting gear etting processing method, object is to avoid stocked carp in netting gear to escape, reduce breeding facility draping number of times, avoid directly contact wear between net stake, promote the inside and outside water body exchange of netting gear etting and stocked carp grows, improves netting gear etting antifouling property and comprehensive benefit is grown in shock resistance, raising oceanic pasture or large-scale culturing net culture in enclosure, to promote oceanic pasture dykes and dams or large-scale culturing net encloses complete set equipment.

double-decker etting first on large-scale netting gear etting at oceanic pasture dykes and dams or large-scale culturing net, large mesh ultra-high molecular weight polyethylene in double-decker etting is through netting bearing part stanchion tractive force and outside high current billow impulsive force, the impact through netting to the medium and small mesh ultra-high molecular weight polyethylene of large-scale netting gear of buffering high current billow, improved little mesh ultra-high molecular weight polyethylene in double-decker etting through the anti-impact force of netting, service life and equipment, greatly improving oceanic pasture dykes and dams or large-scale culturing net encloses by large-scale netting gear etting shock resistance, the present invention encloses stanchion by the large mesh ultra-high molecular weight polyethylene in large-scale netting gear etting through netting and oceanic pasture dykes and dams or large-scale culturing net and directly contacts and prick to tie up and be connected, and little mesh ultra-high molecular weight polyethylene in netting gear etting does not directly contact with stanchion through netting, avoided the direct contact wear of little mesh ultra-high molecular weight polyethylene between netting and stanchion, this has greatly improved oceanic pasture dykes and dams or large-scale culturing net encloses service life and the equipment with large-scale netting gear etting, the present invention encloses manufacture with large-scale netting gear etting through netting material for oceanic pasture dykes and dams or large-scale culturing net by ultra-high molecular weight polyethylene, keeping under equal powerful prerequisite, large-scale netting gear reduces greatly with the more existing common synthetic fibers etting of ultra-high molecular weight polyethylene etting specification, greatly reduced the raw materials consumption of large-scale netting gear etting, develop low-carbon (LC) cultivation, promoted breeding facility equipment, exaggerated or infraclass in the large-scale netting gear etting of the present invention is processed into torsade (comprising that " Z " is to torsade and " S " to torsade) by two phase reverse lays, in effectively having avoided using two with twisting with the fingers to the work accidents such as mutual winding between rope.Result of the test shows, this method is enclosed anti-pollution function and shock resistance with large-scale netting gear etting, prevented that small dimension fish from escaping, reduce large-scale netting gear draping number of times, promoting inside and outside large-scale netting gear etting water body to exchange and stocked carp grows, avoids the aspect technique effects such as direct contact wear between large-scale netting gear etting and stanchion very obvious improving existing oceanic pasture dykes and dams or large-scale culturing net; Compare with the large-scale netting gear etting technology of the existing single layer structure with the manufacture of common synthetic fibers etting, the present invention has outstanding substantive distinguishing features and significant progressive, has greatly promoted China's oceanic pasture dykes and dams or large-scale culturing net and has enclosed complete set equipment.
