Method for assembling underwater copper alloy perforated mesh of pasture type shallow sea fence farming facility

Abstract

The invention relates to a method for assembling an underwater copper alloy perforated mesh of a pasture type shallow sea fence farming facility. Basic components include standard assemblies of copper alloy perforated mesh plates with equilateral triangular profile and standard assemblies of copper alloy perforated mesh plates with right angled triangular profile. Assembly of standard assemblies of copper alloy perforated mesh plates is completed through ultrahigh molecular weight polyethylene extruded profiled lath connecting pieces and ultrahigh molecular weight polyethylene injection moulded corner-end connecting pieces. After the copper alloy perforated mesh plates are assembled, the copper alloy perforated mesh plates are hinged to reinforced concrete piles via endless tube section assembly parts prefabricated on the reinforced concrete pillar and ultrahigh molecular weight polyethylene bars. The method prevents adhesion of marine fouling organisms and retains excellent seawater flowing.

Description

technical field [0001] The invention relates to fence facilities and equipment in the technical field of shallow sea pasture fish culture, in particular to a method for assembling underwater copper alloy punching nets for pasture type shallow sea fence fish culture facilities. 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...

Problems solved by technology

Among them, the copper alloy orthorhombic net 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 net. The disadvantage is that the mesh intersection point moves and rubs, which accelerates the damage at the mesh intersection 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, locked, bent, interlaced, and woven into a square shape. Mesh mesh, the advantage is that the intersection point is relatively mobile and wears little, and the disadvantage is that the mesh is easily deformed after being subjected to external force; copper alloy stretched mesh is made of copper alloy plate, which forms a diamond-shaped mesh after punching and stretching, and its advantage is that the mesh The structure is firm and there is no contact wear between materials. The disadvantage is that the connection between the rigid mesh and the mesh is relatively complicated, and the transportation and offshore installation of the assembled rigid copper alloy tensile mesh structure are difficult.
