Net soft splicing manufacturing method for splicing adjacent two copper alloy chain link fences

Abstract

The invention discloses a net soft splicing manufacturing method for splicing adjacent two copper alloy chain link fences, relates to a method for splicing copper alloy chain link fences in an aquaculture cage, and provides a net soft splicing manufacturing method for splicing adjacent two copper alloy chain link fences for a cage. Nets and suture lines are adopted, and the method is characterized in that: ultrahigh-strength superhigh molecular weight polyethylene nets which are used for fishing and have the same mesh size as copper alloy chain link fences serve as soft net connecting pieces;the copper alloy chain link fences are spliced with the soft net connecting pieces through the suture lines; the strength of the suture lines is not lower than that of superhigh molecular weight polyethylene net lines with the diameter same as the mesh feet thickness of the ultrahigh-strength superhigh molecular weight polyethylene nets which are used for fishing; and meshes, mesh feet and mesh joints of the soft net connecting pieces and meshes, mesh feet and mesh joints of the copper alloy chain link fences needed to be spliced are completely aligned and are subjected to equal-mesh suture according to a suture ratio of 1:1, and the soft net connecting pieces are spliced with the copper alloy chain link fences needed to be spliced.

Description

technical field [0001] The invention relates to a splicing method of a copper alloy orthorhombic mesh of an aquaculture cage. Background technique [0002] Mesh is an important part of the complete set of equipment for cage engineering. Whether it is used for seawater aquaculture or freshwater aquaculture, it needs to use mesh. Cage mesh is mainly divided into synthetic fiber mesh and metal mesh according to its material type. Metal mesh can be divided into trapezoidal mesh, woven mesh and spot welded mesh according to the weaving method; metal mesh can be divided into copper alloy mesh, galvanized wire mesh and steel wire mesh according to the type of matrix material used for weaving mesh. Copper alloy orthorhombic mesh has the advantages of antifouling, antibacterial and corrosion resistance. It was first applied in cage pot fishery, and now it has been applied in freshwater fence nets, freshwater cages and offshore seawater cages. [0003] The splicing method between th...

Problems solved by technology

In the processing and production of cages, effective splicing of two adjacent mesh pieces is an essential and important process. If the splicing between two pieces of mesh is improper, it will lead to the escape of cultured fish in the cage and cause serious economic losses. Therefore, corresponding and effective splicing measures must be taken for the splicing of two adjacent meshes.

At this stage, the method of direct splicing of metal wires is generally used between the copper alloy trapezoidal nets used in cages, which will cause the trapezoidal nets and splicing metal wires to be in the splicing place under the combined factors of sea wind, waves, currents and sea water. Direct wear and tear will lead to serious damage between the oblique mesh and the wire used for splicing, resulting in the occurrence of fish escape accidents; in addition, the whole mesh of copper alloy oblique mesh is a hard mesh in physical state, and the wire The method of direct splicing will have multiple rigid splicing seams in the entire cage system, which brings many hidden dangers to breeding production

When the copper alloy orthorhombic mesh caused by the above-mentioned splicing method is severely worn, the method of replacing the mesh of the entire top cage is generally adopted. This method increases the cost of breeding production. There are defects in the method, which not only restricts the sustainable development of fishery engineering, but also brings difficulties to the widespread use of copper alloy orthorhombic nets, which has become the main factor restricting the promotion and use of copper alloy orthorhombic nets in mariculture.
