Method for processing net-combined-type neritic square net cage

Abstract

The invention discloses a method for processing net-combined-type neritic sea square net cages, relates to an aquaculture net cage, and provides a method for processing neritic square net cages. In the invention, a high-strength rope, a high-strength nylon warp knitting net and a copper alloy inclined square net are adopted. The method provided by the invention is characterized in that a double floating tube square frame structure is adopted in a buoyancy system of the net cage; 28 cylindrical foam floaters with the same specification are arranged under the two rows of floating tube frames; the net system of the net cage combines a first high-strength nylon warp knitting net, a second copper alloy inclined square net and a high-strength nylon warp knitting net used for the bottom of the net cage; after being equipped with ropes, the net at the bottom of the net cage is assembled on a high-density polyethylene frame; a vertical force net is longitudinally arranged along the net from the upper horizontal rope of the first high-strength nylon ware knitting net to the bottom of the net cage; 8 sinking blocks are hung on the high-density polyethylene frame used for the bottom of the net bottom evenly, and the weight of each sinking block is 5kg. The method provided by the invention is suitable to be applied to neritic square net cages.

Description

technical field [0001] The invention relates to a shallow sea square cage for mariculture in the technical field of agricultural science and aquatic products. Background technique [0002] Seawater cages are an important part of my country's marine fisheries. Seawater cages can be divided into square cages, cylindrical cages, spherical cages and conical cages according to their frame shapes. The complete set of equipment and breeding technology of square cages comprehensively apply multidisciplinary technologies such as marine engineering, feed nutrition and disease control, and have the advantages of less one-time investment and low cost. Square cages are currently one of the main types of shallow sea cages in China. Existing shallow sea square net cages generally use a single form of common synthetic fiber netting and three strands of common synthetic fiber ropes, resulting in a large consumption of rope net raw materials; the nets used in existing square net cages are se...

Problems solved by technology

[0005] The outstanding feature of the present invention is that the copper alloy net clothing with antifouling function is used in the manufacture of combined net clothing for square net cages in shallow seas, which effectively solves the antifouling problem of existing net cage net clothing and improves the antifouling of net cage equipment. Pollution function, reduce the number of times for farmers to change nets, reduce the damage to farmed fish caused by frequent net changes, and improve the economic benefits of cage farmers; High-strength rope net materials such as high-strength rope and three-strand high-strength modified polypropylene rope are used in the production of square net cages in shallow seas. Under the premise of maintaining the same strength, the mesh foot thickness, net wire diameter and rope thickness are all higher than existing ones. The common rope net material used for technology is greatly reduced, which not only reduces the consumption of rope net material for the box body of the cage, but also facilitates the exchange of water inside and outside the cage; it not only effectively solves the problem of energy saving and consumption reduction of the existing cage net clothing, but also Promote the growth and development of cage cultured fish, improve the economic benefits of cage farmers; the present invention assembles the bottom of shallow sea square cages with high-strength nylon warp-knitted nets on the square high-density polyethylene pipe frame of 5m * 5m, Effectively reduce the deformation and volume loss of the inner cage in the high-velocity sea environment. The test shows that the above-mentioned equipment method greatly improves the cage volume retention rate and the number of fish that can be cultured in the cage compared with the existing technology, and improves The economic benefits of cage farmers and the development space of seawater cage culture improve the level of cage facilities and equipment; the net clothing system of the present invention adopts "high-strength nylon warp-knitted net (the first net clothing)+copper alloy orthorhombic net (the first net) Ⅱ frame net) + high-strength nylon warp-knitted net (cage net bottom)” effectively avoids the direct wear between the copper alloy net and the cage frame when a single copper alloy net is used, and improves Cage facilities and equipment level; the copper alloy orthorhombic net is used in the horizontal mesh of the cage body after being processed by the special equipment technology of "every 20 meshes in the vertical direction with ultra-high-strength mesh wires along the horizontal direction of the mesh", which is convenient for implementation The lifting operation of the cage body greatly improves the operability of the combined net cage when it catches cultured fish or prevents fish diseases, and the practical effect is very remarkable; the present invention adopts a square double floating tube frame structure, It is beneficial to the daily operation and maintenance of farmers on the net cage; the present invention is convenient for upgrading the technology of the net cage body based on the shallow sea square net cage commonly used in China, and popularizing and applying it
