Abstract

The utility model provides a four-cord polythene stranded rope used for a deepwater net-cage or an ocean trawl, in particular to a rope used for the deepwater net-cage or the ocean trawl. The technical problem to be solved is to reduce the turn-over phenomenon of the rope and improve the safety of the deepwater net-cage or the ocean trawl. The utility model adopts a polythene monofilament for fishing with the diameter of 0.20 millimeter as silk for manufacturing a rope. The rope is characterized in that the total number of silk for manufacturing the rope is 1, 216; the number of strands for manufacturing the rope is 4; the number of yarns for strands is 9; the number of silk for rope yarns is 32; the twist number of the rope yarns is 36T/m; the lay length of the strands is 57.6 millimeters; the lay length of the rope is 59.0 millimeters; a rope heart is filled in the central position of the rope; the twist number of the rope heart is 54T/m; the number of silk for the rope heart is 64; and the rope adopts 'Z/S/Z' direction of twist. The rope is applicable to a wire cable of the deepwater net-cage, a wire cable of an ocean trawl, an inverted anchor cable of a positioning anchor for displacement, a float cable used for a mooring system and a 'special rope material' used for an ocean trawl overlarge mesh.

Description

A kind of deep water mesh cage or ocean trawlnet are with four bursts of polyethylene torsades

Technical field:

The utility model relates to agriculture aquatic products field deep water mesh cage or ocean trawlnet rope.

Background technology

Rope is a widely used material in the fishery, its classification is divided into torsade, makes a rope by twisting the strands together and kernmantle by ropework, be divided into terylene rope, polythene rope, polypropylene rope and caprone cable by rope making with matrix material, be divided into three stranded rope, four-stranded, six strands, stereotyped writing rope and multiply rope by rope structure.

Deep water mesh cage is a kind of intensification marine fish culture outfit that progressively grows up in recent years, has the adult fish quality better and to advantages such as ambient influnence are little.The present national deep water mesh cage quantity of China has reached more than 3200, and main cultured fishes have large yellow croaker, perch, black porgy ， fish and U.S. snapper etc.

China is one of main in the world deep-sea fishing country, and the development of deep-sea fishing has not only alleviated the pressure of fishing for of inshore fishing resource, has brought into play positive effect for national economy and social development, has improved the status of China in international fishery.China's deep-sea fishing mainly comprises drags, angles, encloses etc. several, and wherein the ocean trawling is the important component part of Chinese deep-sea fishing.

Deep water mesh cage or ocean trawlnet are the developing direction of Modern Fishery.Yet, in the evolution of deep water mesh cage or ocean trawlnet, some problem demanding prompt solutions have also been exposed, as deep water mesh cage under the bad weather culture or the ocean trawlnet with three bursts of polyethylene torsades bow tie easily takes place, fishing is studied shortage with four bursts of polyethylene torsades, the basic theory data deficiencies, single and new material R﹠D intensity difference of description of materials etc.

The disrumpent feelings brute force of rope, rope structure, rope making all have important function with matrix material performance, ropework to deep water mesh cage or ocean trawlnet security and wind and wave resistance performance.Deep water mesh cage or ocean trawlnet all have a very important role with the bow tie of rope, the security that improves deep water mesh cage or ocean trawlnet, increase deep water mesh cage or ocean trawlnet wind and wave resistance performance to reducing cage culture or ocean trawlnet with the exploitation of four strands of polyethylene torsade new materials.The kind of rope matrix material and ropework thereof are to influence the key factor of fishing with the mechanical property of torsade material.Be material, adopt conventional ropework can produce common fishing torsade that with common polyethylene monofilament common fishing is general with the tensile mechanical properties of torsade.Have only the performance of employing to reach the polyethylene monofilament of high-class product, special ropework, just can give the torsade excellent mechanical property.Intensity of polyethylene monofilament (the polyethylene monofilament high-class product fracture strength index in SC 5005 " fishing polyethylene monofilament " the marine industry standard is 5.6cN/dtex) and ropework will produce greatly influence with the mechanical property of torsade material to fishing, and the intensity of polyethylene monofilament is influence the especially key factor of mechanical property of performance that fishing uses the torsade material.Ropework also is to influence fishing with the performance of the torsade material especially key factor of mechanical property.Fishing torsade for same diameter, rope making with the total radical of silk, rope making with number of share of stock, rope strand with yarn radical, rope yarn with a silk radical, rope twist per unit, burst lay pitch, the rope lay pitch, rope central authorities whether filling wire rope core, the wire rope core twist, wire rope core with a silk radical, rope making with twist with the fingers to etc., will change the structure of fishing with torsade.

The utility model content

The utility model technical issues that need to address are to reduce cage culture or the ocean trawlnet bow tie of rope, the security that improves deep water mesh cage or ocean trawlnet, increase deep water mesh cage or ocean trawlnet wind and wave resistance performance.

It is the rope making silk with common polyethylene monofilament that the technical solution of the utility model adopts diameter 0.20mm fishing, it is characterized in that rope making with the total radical of silk be 1216, the rope making number of share of stock is 4, rope strand with the yarn radical be 9, the rope yarn with the silk radical be 32, rope twist per unit is that 36T/m, burst lay pitch are that 57.6mm, the rope lay pitch are 59.0mm, to be 54T/m, wire rope core in central part filling wire rope core, the wire rope core twist of rope be 64 with a radical, rope making employing " Z/S/Z " sth. made by twisting is made the tube-contained monofilament that every bundle contains 32 or 64 monofilament with polyethylene monofilament to, i.e. fishing behind minute silk machine branch thread; The tube-contained monofilament that every bundle is contained 32 monofilament twists with the fingers with " Z " that direction is twisted into Z torsade yarn, the tube-contained monofilament that every bundle contained 64 monofilament is twisted with the fingers direction with " Z " and twisted into Z torsade core; Again 9 Z torsade yarns are twisted with the fingers direction with " S " and twist into S torsade thigh; At last 4 S torsade thighs and a Z torsade core being processed into diameter is four bursts of polyethylene torsades of 12.0mm, and wire rope core is filled in the central part of rope.

The utility model combines fishing effectively with polyethylene monofilament and special rope making structure, produce four bursts of polyethylene torsades that are fit to fish production, the result shows through mechanical test, under same diameter (diameter is 12.0mm) condition, disrumpent feelings brute force of the present utility model reaches 15.65kN, and disrumpent feelings brute force is better than the index of GB/T 18674 standard codes.The fishing raising of torsade mechanical property, both reduced cage culture or ocean trawlnet bow tie with rope, guaranteed again deep water mesh cage or ocean trawlnet etc. safe, increase deep water mesh cage or ocean trawlnet wind and wave resistance performance, anchor line, mooring system have favorable economic benefit, social benefit and ecological benefits with ball float rope and ocean trawlnet super large mesh usefulness " special cord material " to can be used as deep water mesh cage guiding principle rope, ocean warp rope, positioning anchor displacement usefulness.
