Half-soft state connecting method between copper alloy woven meshes for cage

Abstract

The invention discloses a half-soft state connecting method between copper alloy woven meshes for a cage, relates to connection of copper alloy woven meshes for the cage, and provides a method for splicing the copper alloy woven meshes for the cage. In the method, sea anchoring cloth, ropes, suture lines and tarpaulin rings are adopted, and the method is characterized in that: the sea anchoring cloth, the ropes, the suture lines and the tarpaulin rings are assembled into half-soft state connecting pieces; the half-soft state connecting pieces are arranged between two copper alloy woven meshes; one end of a high-strength polyethylene rope is fixed at a net joint which is 3 meshes away from the splicing edge of the copper alloy woven meshes; the other end of the high-strength polyethylene rope passes through ring plates of the half-soft state connecting pieces and meshes of the woven meshes in turn; the other end of the high-strength polyethylene rope is fixed at a net joint which is 4 meshes away from the splicing edge of the copper alloy woven meshes; and the half-soft state connecting pieces are spliced with the other copper alloy woven mesh in the adjacent two copper alloy woven meshes together. The method is used for splicing the adjacent two copper alloy woven meshes in the cage.

Description

technical field [0001] The invention relates to a connection method of a copper alloy braided net for a cage in the technical field of aquatic products. Background technique [0002] Net clothing is an important part of the complete set of net cage equipment in the field of agricultural science and aquatic technology. Whether it is used for seawater aquaculture or freshwater aquaculture, net clothing is required. Cage net clothing is mainly divided into synthetic fiber net and metal net according to its material type. According to the weaving method, the metal mesh can be divided into woven mesh, trapezoidal mesh and spot welded mesh; the metal mesh can be divided into copper alloy mesh, galvanized wire mesh and steel wire mesh according to the type of substrate material used for the mesh. Compared with ordinary synthetic fiber netting, copper alloy woven net has the advantages of antifouling, antibacterial and corrosion resistance. It was first applied in cage fishery, and...

Problems solved by technology

In the processing of complete sets of net cage equipment, effective splicing of two adjacent nets is an essential and important process. Improper splicing between two nets will lead to the escape of cultured fish in the net cage, which will bring serious economic problems. loss, therefore, corresponding and effective splicing measures must be taken for the splicing of two adjacent nets

At this stage, the method of direct splicing of metal wires is generally used between copper alloy braided nets for cages, which will cause copper alloy braided nets and splicing metal wires to be damaged at 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 copper alloy braided mesh and the splicing metal wires, resulting in the occurrence of fish escape accidents, which will bring serious economic losses to users; in addition, the copper alloy braided mesh is different from the copper alloy orthorhombic Net, the whole piece of net clothing is a rigid structure and hard net. In the production of net cages, people need to assemble copper alloy braided nets of different sizes according to the size of the net cage. The method of direct splicing of metal wires will be used in the entire net cage system. There are multiple rigid seams, which bring many hidden dangers to the breeding production

When the copper alloy braided net caused by the above-mentioned splicing method is severely worn, the method of replacing the net clothing of the entire cage is generally adopted. This method greatly increases the cost of breeding production; this has both restricted the sustainable development of fishery engineering. It has also brought difficulties to the widespread use of copper alloy braided nets, and has become the main factor restricting the promotion and use of copper alloy braided nets in marine aquaculture.

There are defects in the splicing method between the copper alloy braided nets used in the existing cages, and its safety and fishery adaptability are poor, and it is difficult to meet the special needs of the cage facilities laid in the ocean
