Abstract
The utility model relates to a super-high strong netting applied in pelagic trawl nets or deepwater net cages, which belongs to the fishery technical field. In order to improve the hydrodynamic performances of netting gears, the safety of netting gears and the wind wave resistant performances of pelagic trawl nets or deepwater net cages, the super-high strong netting provided in the utility model adopts a single-deadlock structure formed by weaving net wires into rhombic mesh shapes. The super-high strong netting is characterized in that three strands of super-high strong polyethylene wires are twisted into a Z direction in an external twist number of 148 T/m; the super-high strong polyethylene wire strands make a super-high strong polyethylene fiber having a line density of 4800 D and a breaking tenacity reaching 39.0 cN/dtex twisted towards an S direction. The netting not only ensures the safety of pelagic trawl nets or deepwater net cages but also improves the hydrodynamic performances of net gears and enhances the wind wave resistant performances of the pelagic trawl nets or the deepwater net cages. It is feasible to popularize the application of the netting in pelagic trawl net or deepwater net cage breeding industries.
Description
Technical field
The utility model relates to a kind of in the aquatic products technical field and can be used for the strong etting of superelevation that ocean trawlnet or deep water mesh cage are used.
Background technology
Etting is a widely used material in the fishery, and its sorting technique is a lot, is divided into copper alloy etting, polyethylene monofilament etting, polyamide fiber etting, polypropylene fibre etting, polyester fiber etting and ultra high strength polyethylene fiber etting by matrix material; Be divided into knot clothing and knotless net clothing two big classes by the anastomose type.What is called has the clothing of knotting to be meant by netting twine by making the etting that structure becomes.Syndeton between the order pin in the clothing of knotting is arranged, be called for short " knot "; Its form has slip-knot, fast knot, two fast knots etc.; According to the kind of anastomose, the clothing of knotting can be subdivided into slip-knot etting, single fast knot etting, two fast knot etting and the distortion clothing of knotting.So-called knotless net clothing is meant that each the line thigh by netting twine or netting twine is interweaved and the etting that does not have anastomose that constitutes; The knotless net clothing can be subdivided into through netting clothing, pigtail netting clothing, strand by its structure and twist with the fingers etting, inserts and twist with the fingers etting, plain weave etting and moulding etting.The clothing of knotting can weave by hand, also can the machine braiding.
It is two importances of marine fishery development in recent years that deep water mesh cage is cultured with long range fishing, and the needed intensification marine fish culture of deep water mesh cage outfit has higher requirement with the required etting of ocean trawlnet at aspects such as security and wind and wave resistance streams.And the etting that uses at present is with common composite fibre materials, the conventional knitmesh explained hereafter of employing, its mechanical performance is general, in use especially under the bad weather its intensity, structure, matrix material performance, knitmesh technology all present serious deficiency, press for a kind of strong etting of superelevation of ocean trawlnet or deep water mesh cage that can be used for to adapt to the needs of production.
Summary of the invention
The utility model technical issues that need to address are to improve the security of the hydrodynamic performance of netting gear, raising netting gear and the wind and wave resistance fluidity energy that improves ocean trawlnet or deep water mesh cage.
The technical solution adopted in the utility model is: a kind ofly can be used for the strong etting of superelevation that ocean trawlnet or deep water mesh cage are used, this etting adopts netting twine to be made into single fast knot structure of diamond mesh shape, it is characterized in that: the outer twist that described netting twine adopts 148T/m with three strands of ultra-high strength polyethylene line thighs twist with the fingers " Z " to; The interior twist that described ultra-high strength polyethylene line thigh adopts 258T/m with 1 line density be 4800D, fracture strength reach 39.0cN/dtex ultra high strength polyethylene fiber by " S " to twisting.
The nominal diameter of described netting twine is 2mm.
Described diamond mesh, the long 67mm that is of a size of of its water chestnut.
The intensity of etting matrix material and knitmesh technology are to influence the principal element of fishing with the etting mechanical performance.The knitmesh of common polythene etting is 5.6cN/dtex with fishing with polyethylene monofilament high-class product fracture strength index, the ultra-high strong fiber fracture strength that the utility model adopts can be up to 39.0cN/dtex, it act as by improving the traditional knitmesh intensity with matrix material, and then improves the mechanical performance of fishing with etting; Simultaneously the used netting twine of this etting adopt the outer twist with three strands of ultra-high strength polyethylene line thighs twist with the fingers " Z " to, the twist twists with the fingers " S " to having changed the structure of fishing with etting on ultra-high strength polyethylene line thigh in adopting, for the fishing etting of identical size of mesh and netting twine rugosity, this etting is largely increased in the performance aspect brute force, the wind and wave resistance stream.This etting shows through the mechanical test result, under identical netting twine diameter condition, and this etting, its mesh brute force is up to 150.0daN, and it increases by 135.5% than the mesh of the equal specification polyethylene etting of GB/T 18673-2002 standard code is powerful.This etting adopts diamond mesh, and etting can be by the mutual handover of netting twine of diagonal cross at the active force that is subjected to different directions, and follows the corresponding change of mesh shape and make active force obtain buffering, thereby improves the mechanical performance of etting.The fishing raising of etting mechanical performance, both guaranteed the safety of ocean trawlnet or deep water mesh cage, improve hydrodynamic performance, increase ocean trawlnet or the deep water mesh cage wind and wave resistance fluidity energy of netting gear again, it is applied on ocean trawlnet or deep water mesh cage aquaculture all has feasibility.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged drawing of netting twine among Fig. 1.
Among the figure, 1, netting twine, 2, diamond mesh, 3, single fast knot, 4, ultra-high strength polyethylene line thigh, 5, " Z " to, 6, " S " to.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, a kind ofly can be used for the strong etting of superelevation that ocean trawlnet or deep water mesh cage are used, this etting adopts netting twine 1 to be made into single fast knot 3 structures of diamond mesh 2 shapes, the size of diamond mesh 2, the i.e. long 65-70mm that is controlled at of water chestnut.
As shown in Figure 2, netting twine 1 adopts three strands of ultra-high strength polyethylene line thighs 4 to twist with the fingers " Z " to 5, and ultra-high strength polyethylene line thigh 4 adopts 1 fishing to press " S " to 6 twistings with ultra high strength polyethylene fiber, and the netting twine nominal diameter of making is 2mm.
During twisting, three strands of ultra-high strength polyethylene line thighs 4 adopt the outer twist of 148T/m twist with the fingers " Z " to; The line density of ultra high strength polyethylene fiber is 4800D, fracture strength 39.0cN/dtex, adopts the interior twist of 258T/m it to be twisted into " S " to 6.
The strong etting of superelevation according to above-mentioned parameter is made into the results showed, this etting, and its mesh brute force is up to 150.0daN, and it increases by 135.5% than the mesh of the equal specification polyethylene etting of GB/T 18673-2002 standard code is powerful.
