Description
Technical field:
The utility model relates to the deep water mesh cage rope.
Background technology:
Deep water mesh cage is a kind of intensification marine fish culture outfit that development in recent years is got up; its integrated application multidisciplinary technology such as new material, ocean engineering, electromechanical instrument instrument, automatic control technology, environmental protection; have production efficiency height, adult fish quality better, remarkable in economical benefits and, become the main pattern of marine fish culture gradually advantages such as ambient influnence are little.China's deep water mesh cage is breeded fish and is started from the polyethylene framework floating type deep water mesh cage of Lingao, Hainan in 1998, succeeded in developing at present the deep water mesh cage of multiple patterns such as floating cage, submerging cage, elevated live cage, deep water mesh cage quantity has reached more than 3200, and main cultured fishes have large yellow croaker, perch, turbot, U.S. snapper and egg-shaped pompano.Yet, in the evolution of deep water mesh cage, also exposed some problem demanding prompt solutions, under bad weather, deep water mesh cage small dimension three-ply polythene torsade fracture accident happens occasionally.
Rope is a widely used material in the deep water mesh cage aquaculture, be divided into common rope and high-strength rope by the rope performance, be divided into torsade, make a rope by twisting the strands together and kernmantle by ropework, be divided into polyethylene rope, polypropylene rope and polyamide rope by rope making with matrix material, be divided into three stranded rope, four-stranded, six strands and stereotyped writing rope by rope structure.Small dimension three-ply polythene torsade between diameter 7mm～23mm is used for net cage suspension sinker and uses anchor line and mooring system ball float rope with guiding principle rope, net cage casing mesh bag with guiding principle rope, positioning anchor displacement.Deep water mesh cage is the common polythene monofilament with the matrix material that adopts in the small dimension three-ply polythene torsade processing at present.Common polythene monofilament Grade A fracture strength standard index is 6.1g/D, and ultimate strength is lower, and the deep water mesh cage of its twisting is also relatively low with the disrumpent feelings brute force of small dimension three-ply polythene torsade.High density polyethylene (HDPE) is the fishing high-strength polyethylene monofilament that raw material adopts the hot drawing-off self-reinforcing of high temperature high power technology to produce, its fracture strength is up to 9.6g/D, uses in the high-strength three-ply polythene torsade manufacturing with small dimension for improving the deep water mesh cage security, reduce the deep water mesh cage energy consumption, increasing deep water mesh cage wind and wave resistance performance and economic benefit has important effect at deep water mesh cage.
The utility model content:
The utility model technical issues that need to address are disrumpent feelings brute forces that the deep water mesh cage between raising diameter 7mm～23mm is used the torsade of small dimension three-ply polythene, to adapt to the security that it is used in fishery.
The technical solution of the utility model adopts fishing high-strength polyethylene monofilament, it is characterized in that fishing high-strength polyethylene filament diameter 0.20mm, and every rope yarn is twisted with the fingers into the rope yarn that diameter is 1.8mm with 36 monofilament; The strand diameter of twisting three-ply polythene torsade equals the product of torsade diameter and stranding empirical coefficient, and the stranding empirical coefficient adopts 0.49; Every rope strand equals the square value of strand diameter and the ratio of rope yarn diameter with rope yarn quantity, and every rope strand adopts positive integer with rope yarn quantity; Rope making with twist 24T/m～29T/m, stranding with twist 40T/m～46T/m, stranding with the rope yarn twist with the fingers to be " Z " to, rope strand twist with the fingers to for " S " to, torsade twist with the fingers to be " Z " to.
The utility model is owing to combine fishing preferably with high-strength polyethylene monofilament new material and specific rope making structure, make the suitable deep water mesh cage high-strength three-ply polythene torsade of small dimension between diameter 7mm～23mm, compared with prior art this torsade not only has the high advantage of disrumpent feelings brute force, and have superiority of effectiveness and a wind and wave resistance performance advantage, can reduce water resistance, the energy efficient of deep water mesh cage, improve security, production efficiency and the economic benefit of deep water mesh cage.
Description of drawings:
Accompanying drawing is the schematic diagram of deep water mesh cage with the high-strength three-ply polythene torsade of small dimension structure.
The specific embodiment:
Implement best way of the present utility model below in conjunction with description of drawings:
Embodiment 1: the high-strength three-ply polythene torsade of small dimension of twisting diameter 18.0mm deep water mesh cage: the diameter 0.20mm fishing high-strength polyethylene monofilament that adopts high drafting self-reinforcing technology to produce, and its strength ratio common polythene monofilament improves 50%; Tube-contained monofilament divides silk to become the rope making yarn with a monofilament 2 through minute silk machine, and every rope yarn 1 usefulness monofilament quantity is 36, by rope machine with " Z " to 36 fishing are twisted with the fingers into the rope yarn 1 that diameter is 1.8mm with high-strength polyethylene monofilament 2; Determine that by the product of torsade 3 diameter 18.0mm and stranding empirical coefficient 0.49 rope strand 4 diameters are that 8.8mm, every rope strand are 24 ≈ (8.8 ÷ 1.8) with rope yarn quantity
