Combined box body system used for floating net cage and mated frame system thereof

Abstract

The invention provides a combined box body system used for a floating net cage and a mated frame system thereof, relating to a seawater cultivation floating net cage. A copper alloy inclined square mesh, a copper alloy weaving mesh, high-strength polyamide warp knitting fishnet, ropes, a galvanized iron pipe and foam buoys. The combined box body system is characterized in that a floating net cageframe system comprises two rows of square galvanized iron pipe frames; the foam buoys are distributed below the two rows of galvanized iron pipe frames; the fishnet system of a net cage body combinesa first high-strength polyamide warp knitting fishnet, a second copper alloy inclined square mesh and the copper alloy weaving mesh used for the bottom of the net cage'; the edge installing wire ropeof the fishnet at the bottom of the net cage is assembled on a square high-strength polyamide pipe frame; the high-strength polyamide pipe frame and a horizontal wire rope at the lower edge of the second copper alloy inclined square mesh are connected by an ultrahigh-strength rope; and a vertical force net is installed in the vertical direction of the fishnet and extends to the edge wire rope of the copper alloy weaving mesh used for the bottom of the net cage.

Description

Technical field [0001] The invention relates to a floating net cage for mariculture in the field of agricultural science and aquaculture technology. Background technique [0002] Sea cages are an important part of my country's marine fisheries. According to the working methods of seawater cages, they can be divided into three categories: floating cages, sinking cages and lifting cages, among which the proportion of floating cages reaches 52.9%. Floating cages are mainly used for breeding and production on the surface of open seas. The advantages of this type of cage are convenient daily operation and maintenance (net replacement, cleaning, feeding), and easy observation of the cage culture; simple structure and low cost The disadvantage of this type of cage is that the cage is directly exposed to the sea surface, and wind and waves directly affect the cage frame, which requires high strength of the cage and frame materials; at the same time, the cage floating on the sea surface ...

Problems solved by technology

[0005] The outstanding feature of the present invention is that the net cage body system adopts copper alloy orthorhombic mesh and copper alloy woven net with antifouling function, which effectively solves the antifouling problem of ordinary net clothes used in existing net cages, and improves the antifouling of net cage equipment. Pollution function, reduce the number of times for farmers to change nets and the damage to cultured fish caused by frequent net changes, improve the economic benefits of net cage farmers and the development space for seawater net cage culture, and improve the equipment level of net cages; Copper alloy net clothes are assembled on the square high-density polyethylene pipe frame of 10m × 10m. The test shows that the above-mentioned equipment method has greatly improved the box volume retention rate of the net cage compared with the prior art, and improved the economic benefits of the net cage farmers. Seawater net cage culture development space, improve the level of net cage facilities and equipment; the net clothing system of the present invention adopts "high-strength polyamide warp-knitted net clothing (the first net clothing)+copper alloy orthorhombic net (the second net clothing)+ Copper alloy braided net (cage net bottom)" combined netting form effectively avoids the direct wear between the copper alloy netting and the cage frame when the entire box netting adopts a single copper alloy netting form, and the lifting net The equipment level of the cage facilities; the present invention adopts a square double-row galvanized iron pipe frame structure on the combined net cage, which not only effectively prevents the corrosion of the cage frame by seawater, but also facilitates the daily operation and maintenance of the cage by farmers; In the present invention, high-performance rope net materials such as high-strength polyamide warp-knitted net clothing, ultra-high-strength polyethylene rope, and ultra-high-strength net wire are used in the processing and manufacturing of the combined box system and its supporting frame system for floating net cages and the mutual connection between them. Connection, under the premise of maintaining the same strength, the thickness of the mesh foot, the diameter of the mesh wire and the thickness of the rope are greatly reduced compared with the ordinary rope mesh material used in the prior art, which not only reduces the consumption of rope mesh materials in the entire box system, but also It is conducive to 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 promotes the growth and development of fish in cage culture, and improves the economic benefits of cage culture
