A high-permeability copper alloy tensile mesh and its connection method

Abstract

The invention relates to a high penetration rate copper alloy stretching mesh and a connecting method thereof; the mesh is formed by stretching a copper alloy band belt through a punching slit along a direction vertical to the copper alloy band belt plane; the mesh has non-isosceles hexagon sieves; a horizontal mesh bar 4 and an oblique mesh bar 5 are different in length; the horizontal mesh bar laths on two sides of the mesh are provided with first plug ports used for connecting adjacent meshes; the oblique mesh bars on top and bottom of the mesh are correspondingly provided with second plug ports used for connecting adjacent meshes. Adjacent meshes are plugged, clamped and fastened in the transverse direction; the horizontal mesh bars are correspondingly plugged through second plug ports in the vertical direction; a second copper alloy wire rod can carry out reversely twisting on adjacent sieves so as to clamp and connect horizontal mesh bars. The copper alloy stretching mesh is stable and lossless in sieve structure, can reduce mesh incident flow area, can reduce biology attachment, and can improve water penetration rate; the copper alloy stretching mesh is simple in connecting method, convenient to dismount, stable in connecting structure, and can prevent seawater corrosion caused by different metal potential differences.

Description

technical field [0001] The invention relates to a fence facility for fish culture in a shallow sea pasture, in particular to a high-permeability copper alloy stretched mesh and a connection method thereof. Background technique [0002] With the increase of human demand for high-quality protein sources and the shortage of natural fishery resources worldwide, the use of shallow sea water resources for fish farming has promoted the development of seawater cage culture models and technologies. Due to the application of new materials and new technologies, seawater cage facilities have enhanced wind and wave resistance, which has also promoted the advancement of cages from nearshore to offshore waters. Based on the demand for the healthy growth and quality improvement of farmed fish, based on the large-scale cage facilities, a large area of ​​water is formed by fences between shallow sea waters or natural bays and islands for pasture-style fish farming, which has become a healthy ...

Problems solved by technology

Among them, the copper alloy orthorhombic mesh structure is made of a single copper wire in a wave-like shape, which is threaded and hung in parallel one by one to form a mesh. The advantage is that the connection between the mesh and the mesh is convenient, and it can be folded in one axial direction, which is convenient for transportation; The disadvantage is that the movement and friction of the mesh junction point accelerates the damage at the mesh junction point of the copper alloy orthorhombic mesh.

The structure of the copper alloy braided mesh is that two-phase vertical copper wires are bent and rolled in two directions, and then locked and bent and interlaced to form a square mesh. The advantage is that the relative movement of the intersection points is small; the disadvantage is that friction at the intersection points will also occur under the impact of waves. , and the woven mesh is easily deformed by external force

Copper alloy stretched mesh is made of copper alloy strip, which is punched and stretched to form a diamond-shaped mesh. Its advantage is that the mesh structure is firm and there is no contact wear between materials; the disadvantage is that copper alloy strip is punched and stretched. The single mesh size is limited by the processing equipment. When it is used in large-scale shallow sea fence facilities, it is necessary to solve the effective connection between the meshes, and the water permeability of the diamond mesh structure currently used is low.
