Problems solved by technology

Among them, the copper alloy orthorhombic net is more commonly used. Its structure is made of a single copper wire in a wave-like shape. After being threaded and hung by multiple parallel wires, a mesh is formed. The advantage is the strain capacity of the box under the sea current condition. It is strong, not easy to break, the connection between the net and the net is convenient, and it can be folded in one axial direction, which is convenient for transportation; the disadvantage is that the handover point of the net formed by the hook is movable, and the net box body is formed in the waves and currents of the sea. Under the action of the mesh junction, the mesh junction is always in a state of movement and friction, causing the oxidation protective film formed on the surface of the copper alloy material in seawater to be continuously eroded, which accelerates the damage of the mesh junction of the copper alloy orthorhombic mesh.
Copper alloy stretched mesh is made of copper alloy plate, which forms a rhombic mesh mesh after punching and stretching. Its advantages are stable mesh, firm structure, and no contact, movement and wear between materials; the disadvantage is that when building the box , the connection between the rigid mesh and the mesh is relatively complicated, and the rigid structural box has poor strain capacity under sea current conditions, which is easy to cause deformation of the mesh or corner breakage, resulting in damage to the cage body
At the same time, it is difficult to transport and install the rigid copper alloy stretched net after it is assembled into a net cage in the factory (or on the shore) and installed at sea.

Abstract

The invention relates to a modular splicing type copper alloy stretching net box and n assembling method thereof. The modular splicing type copper alloy stretching net box comprises a vertical main stressing high-strength polyester fiber belt main framework tape standard part and a horizontal secondary stressing high-strength polyester fiber belt secondary framework tape standard part which are fixed at a crisscross connecting point to form a grid shaped single-side net box tape framework which has the characteristics of flexibility and elasticity; a prefabricated copper alloy stretching net standard module is assembled into each frame of the grid shaped single-side net box tape framework through a prefabricated quick connecting part to form the modular splicing type net box body single-edge side net; two side edges of the single-edge side net are connected through the quick connecting part, or a plurality of single-edge side nets are provided with corner flexible connecting adapting standard parts and bottom nets and then assembled to be a copper alloy stretching net box body. The modular splicing type copper alloy stretching net is applicable to modular and standard production and convenient to be quickly mounted in the sea; a marine breeding net can be maintained well and prevented from being attached by marine fouling organisms; the inside and outside water of the net box body can be exchanged well.

Description

technical field [0001] The invention belongs to the technical field of marine aquaculture net cage equipment, and particularly relates to a rapidly modularized and assembled copper alloy tensile net cage and its assembly that can prevent marine fouling organisms from adhering in seawater and maintain good water exchange inside and outside the net cage. method. Background technique [0002] Marine aquaculture cages can be divided into gravity type, tension type formed by mooring and buoyancy and self-supporting type according to the shape of the cage body in seawater. [0003] Existing gravity cages usually use high-density polyethylene floating pipes or metal pipes or wooden boards with buoyancy materials to form the cage floating frame; high-density polyethylene monofilament fibers, polyamide multifilament fibers or ultra-high molecular weight polyethylene fibers The woven netting or non-knotting meshes are assembled into a box body, and sinkers are suspended at the bottom...
