Method for making turbot cultivation net cage

Abstract

The invention discloses a method for making a turbot cultivation net cage, and relates to making of turbot cultivation equipment. In the method, a galvanized iron pipe, a high-strength single fast knot polyethylene net, a high-strength polyamide wrap knitting net, a high-strength fishing polyethylene rope, a cylindrical plastic foam floater, high-strength fishing lines and a copper alloy (LC68700) stretching net are used. The method is characterized in that: a net cage floating support is made of a hot-dip galvanized iron pipe; the cylinder plastic foam floater is coated with waterproof clothand a layer of waste netting; a netting system for the net cage consists of a double-layer synthetic fiber netting serving as a first netting and the combined copper alloy (LC68700) stretching net serving a second netting; the first netting and the second netting are connected in a vertical half-soft mode; the net bottom of the net cage is provided with a square synthetic fiber netting; a square galvanized iron pipe framework is hung under the net bottom of the net cage; horizontal outlines and vertical force outlines are arranged on a side-surface netting of a cage body of the net cage; and the net cage floating support is connected with a floating rope frame matched with the net cage system through by a cable.

Description

technical field [0001] The invention relates to a manufacturing method of turbot breeding equipment. Background technique [0002] Turbot farming is an important part of mariculture. The netting used in synthetic fiber netting cages for turbot breeding is seriously fouled and adhered during the breeding production, resulting in unsmooth water exchange inside and outside the box, frequent net changes, high labor intensity for net changes, and consumption of raw materials for rope nets. Larger and damaged box nets will be discarded by farmers, which will affect the breeding efficiency. Metal mesh net cages for turbot culture use ordinary aluminum alloy mesh, stainless steel mesh or wire mesh materials. Ordinary aluminum alloy mesh, stainless steel mesh or wire mesh materials will cause serious damage to the metal floating frame of the metal mesh cage during cage culture. Direct wear and tear will lead to serious accidents that the metal mesh cages for mariculture will be dam...

Problems solved by technology

[0005] The outstanding feature of the present invention is that the copper alloy LC68700 stretched net with anti-fouling and anti-corrosion functions is used in the production of combined net clothing for turbot breeding cages, which effectively solves the anti-pollution of the existing net cage net clothing. and anti-corrosion problems, improve the anti-fouling and anti-corrosion functions of cage equipment, reduce the number of times cage farmers change nets, reduce the level drift of net clothing, reduce the damage to farmed fish caused by frequent net changes, and improve the quality of net cage farmers. economic benefits; the present invention uses high-strength fishing polyethylene ropes, high-strength single-knot polyethylene nets, high-strength polyamide warp-knitted nets, and high-strength fishing net wires and other energy-saving and consumption-reducing rope net wire materials for the production of net cages. Under the premise that the mesh foot thickness of the net, the nominal diameter of the net wire and the nominal diameter of the rope are all greatly reduced compared with the common rope and net wire materials used in the existing net cages, it not only reduces the consumption of rope net wire materials for the net cage box, but also facilitates the net cage The exchange of internal and external water bodies; it not only solves the problem of energy saving and consumption reduction of the existing net cages, but also promotes the growth and development of fish cultured in cages, improves the economic benefits of cage farmers, and promotes energy saving and consumption reduction in fishery production; A square galvanized iron pipe frame with a perimeter of 20.0m is hung under the bottom of the turbot culture cage to ensure that the cage has a volume retention rate. The test shows that this method is better than that of the net without a galvanized iron pipe frame at the bottom of the cage. The cage greatly improves the cage volume retention rate of the cage and the number of fish that can be cultured in the cage, improves the cage culture space, and improves the equipment level of the cage facilities; the invention adopts hot-dip galvanized iron pipes to effectively prevent cold-dip galvanized iron pipes in seawater corrosion problem; the netting system of the present invention adopts the form of combined netting, which effectively avoids the direct wear between the metal netting and the rigid floating frame system when the prior art adopts a single metal netting form, and improves the equipment level of the cage facilities ; The present invention outsources 1-2 layers of waterproof cloth and 1 layer of net clothing on the cylindrical plastic foam float, which greatly improves the service life and safety of use of the cylindrical plastic foam float of the net cage buoyancy system; the present invention uses a square galvanized iron pipe frame with A certain distance is hung on the bottom of the net cage with synthetic fiber ropes, which effectively prevents direct wear and direct contact corrosion between the second net and the hot-dip galvanized iron pipe, and improves the life of the galvanized iron pipe frame and the facilities and equipment of the net cage. level; according to the characteristics that turbot is a non-swimming fish, the present invention selects the high box netting height of 2.8m for use, which saves the manufacturing cost of turbot breeding net cage; The side length of the box, and the width of the copper alloy LC68700 stretched net is 1.0m and the length can be more than 5.0m. In the second combined netting, the copper alloy LC68700 stretched net is installed horizontally instead of other net cages The medium copper alloy LC68700 tensile net adopts vertical installation, which greatly reduces the semi-soft connecting material required for the entire cage body compared with the longitudinal installation of the copper alloy LC68700 tensile net in the cage, and effectively realizes energy saving and reduction in fishery production. consumption; the present invention uses copper alloy LC68700 stretching nets to be used for long-term cultivation and production in net cages, and its waste copper alloy LC68700 stretching nets can be recycled at a high price, while the synthetic fiber nets used in existing net cages can be used in 1 to 2 years. After aquaculture production, the waste nets are generally discarded by farmers or breeding units; in addition, this solution can increase the overall number of fish cultured, reduce fish diseases, increase fish survival rate, and reduce daily net replacement costs compared with traditional cages of the same size Compared with traditional net cages, it has a cost-effective advantage; in the present invention, the soft connection of nets, the nets at the bottom of the net cage, and the ropes used for assembling the nets are all treated with anti-algae agent for fishing nets, which greatly improves the quality of the nets. The comprehensive antifouling function of the body net clothing system; the present invention uses the ropes after heat-setting treatment for both the horizontal and vertical forces, which effectively avoids the deformation of the cage system when the existing cages use ropes that have not been heat-set. impact, greatly improving the strength, service life and volume retention of the net cage; the present invention uses opposite twisted ropes for the lower horizontal line of the second net and the edge line of the net at the bottom of the net to reduce the Kink effect of adjacent cables with the same lay direction in use
