Adjacent netting semi-flexible connection method for copper alloy mesh grid

Abstract

The invention provides an adjacent netting semi-flexible connection method for a copper alloy mesh grid, relating to an aquaculture net cage netting connection method and needing to provide a netting semi-flexible connection method. A cylinder braid, a rope, a suture line and a tarpaulin ring are adopted. The connection method is characterized in that the cylindrical braid, the rope, the suture line and the tarpaulin ring are processed and assembled into a semi-flexible connecting member arranged between two adjacent copper alloy mesh grids, one end of the suture rope is fixed on a net junction at a distance of 3 meshes from the connecting part of the copper alloy mesh grids, the other end of the suture rope sequentially penetrates through eye rings of the semi-flexible connection member and net meshes on the copper alloy mesh grids, the eye rings of the semi-flexible connecting members and the net meshes of the copper alloy mesh grids are sutured and sewed in a suture ratio of 2:3, after the suture rope penetrates through all eye rings at one side of the semi-flexible connection member and corresponding net meshes on the copper alloy mesh grids, the suture rope is fixed on a net junction at a distance of 4 meshes from the connecting edge of the copper alloy mesh grids, and the semi-flexible connecting member is connected with the other copper alloy mesh grid of the two copper alloy mesh grids together by using the same method.

Description

technical field [0001] The invention relates to a mesh connection method for aquaculture net cages. Background technique [0002] Mesh is an important part of cage equipment, and both marine aquaculture cages and freshwater aquaculture cages use mesh. Cage mesh is mainly divided into synthetic fiber mesh and metal mesh according to its material type. According to the weaving method, the metal mesh is divided into woven mesh, trapezoidal mesh and spot welded mesh; the metal mesh is divided into copper alloy mesh, galvanized barbed wire mesh and steel wire mesh according to the type of substrate material used for the mesh. Copper alloy woven mesh has the advantages of antifouling, antibacterial and corrosion resistance. It was first used in cage pot fishery, and is currently also used in freshwater fence nets, freshwater cages and offshore seawater cages. [0003] The connection method between the adjacent nets in the cage is directly related to the safety of the complete eq...

Problems solved by technology

At this stage, the method of direct connection of metal wires is used between copper alloy braided nets for cages, which will cause the braided nets and connecting metal wires to be directly worn at the joints under the combined factors of sea wind, waves, currents and sea water. Serious damage to the wires between the woven nets and their connections, leading to fish escape accidents

Copper alloy woven mesh is different from copper alloy orthorhombic mesh. The whole mesh is a hard mesh in physical state. The cage needs to assemble different specifications of copper alloy woven mesh according to the size requirements. Because it is directly connected by metal wire method, there are many rigid joints in the whole cage system, the safety and fishery adaptability are poor, and it is difficult to meet the special needs of the cage facilities laid in the ocean
