Marine ranching dike netting gear component assembly method

Abstract

The invention discloses a marine ranching dike netting gear component assembly method, wherein a double-layer fiber net, a medium-soft connection net and a woven net are used. The marine ranching dike netting gear component assembly method is characterized in that an upper margin line of the woven net and a lower line of the double-layer fiber net are bound and tightened with a single fast knot through a sixteen-strand polyester woven rope with the diameter of 4.6mm and are spaced by 5cm; next, a lower line of the medium-soft connection net and a connecting steel cable on the woven net are bound and tightened with a single fast knot through a sixteen-strand polyester woven rope with the diameter of 4.6mm and are spaced by 5cm; then, an upper line of the medium-soft connection net and a connecting net line on the double-layer fiber net are bound and tightened with a single fast knot through a sixteen-strand polyester woven rope with the diameter of 4.6mm and are spaced by 5cm; after an upper line of the double-layer fiber net, the upper line of the medium-soft connection net, the lower line of the medium-soft connection net, a lower margin line of the woven net and the double-layer fiber net are subjected to anti-dirt treatment, a large-mesh ultra-high molecular weight polyethylene warp knitting net is directly bound, connected and fixed to a marine ranching dike netting gear pile.

Description

technical field [0001] The invention relates to the technical field of marine pasture dam net gear. Background technique [0002] In view of the different factors such as breeding methods and stocking fish specifications, the mesh size of nets in sea ranch dyke nets also varies greatly; according to the size of the mesh, nets with a mesh size of no more than 50mm are called small meshes. Net (clothing), the mesh size of which is not less than 200mm is called large mesh net (clothing), such as small mesh polyamide net, large mesh amide net, etc. According to the number of layers of the net in the net, the single-layer structure synthetic fiber net is called single-layer fiber net or single-layer fiber net, and the double-layer structure synthetic fiber net is called double-layer fiber net or double-layer fiber net. The three-layer structure synthetic fiber net clothing is called a three-layer fiber net or a three-layer fiber net clothing. Sea pasture dyke nets are far from ...

AI Technical Summary

Problems solved by technology

Existing single-layer fiber nets for marine ranch dyke nets are seriously attached to fouling organisms such as barnacles, and the direct connection between the single-layer fiber nets and the piles is very easy to wear, and the single-layer fiber nets have broken nets and fish escape accidents in severe weather such as typhoons , fish escape accidents not only bring losses to farmers or breeding enterprises, but also a large number of escaped farmed fish sometimes destroy the biological chain in local sea areas, thus causing serious losses to the entire industry and even marine ecology

There are still some technical problems that need to be solved urgently in the development of marine ranch dyke nets, such as the assembly method of marine ranch dyke nets, how to resist impacts of marine ranch dyke nets, and the resistance of marine ranch dyke nets to marine biofouling. Problems, wear and tear between net piles of marine ranch dyke nets, poor exchange of water inside and outside the marine ranch dam nets, etc.
