Splicing and lifting type sea-area cultivation net cage

Abstract

The invention provides a splicing and lifting type sea-area cultivation net cage. The splicing and lifting type sea-area cultivation net cage is characterized in that the whole outer frame of the cultivation net cage is of a cone frustum shape, and the bottom surface diameter of the outer frame of the cultivation net cage is larger than the top surface diameter of the outer frame of the cultivation net cage; the outer frame of the cultivation net cage is assembled by a plurality of trapezoid frames with narrow upper portions and wide lower portions, a net rack is mounted on the bottom surface of the cultivation net cage, adjacent trapezoid frames are mounted together through flanges and connectors, a float is arranged at the bottom of each trapezoid frame, each float is provided with an air inlet pipe and a draining outlet, and the floats are used for controlling the floating of the cultivation net cage; fish shelter anchors are hung to the cultivation net cage through anchor cables, and the middles of the anchor cables are connected with floater components suspended above through inhaul cables. Compared with a traditional deep-sea rigid net cage, the splicing and lifting type sea-area cultivation net cage has the advantages that the cone-frustum-shaped splicing structure of the net cage adopts a cone-frustum-shaped multi-edge structure, net cage strength is enhanced while modularized, standardized and miniaturized batch factory production is achieved, manufacturing precision is guaranteed, transportation is facilitated, and on-site assembling and net cage putting are achieved.

Description

technical field [0001] The invention relates to the field of marine aquaculture, in particular to a splicing and lifting type marine aquaculture cage. Background technique [0002] Since 1999, my country first introduced large-scale deep-sea anti-wind and wave cage equipment from Norway, and deep-sea cages have developed rapidly in my country. Later, more advanced Norwegian HDPE cages and American marine station cages were introduced. In 2001, the deep-sea cages independently developed in China entered the production stage. [0003] As a high-density and intensive farming method, deep-sea cage aquaculture has developed rapidly in the world in recent years, and is developing in the direction of automation, multi-function, large-scale and deep water in the open sea. Fish production and quality have declined. This leads to the tendency of breeding to deep sea. Most of the deep-sea cages are rigid cylindrical and polygonal prism-shaped large cages, which can be optimized to s...

AI Technical Summary

Problems solved by technology

Fixed net cages have problems such as poor rigidity, large volume, and need for on-site welding and overall placement, which affect the processing quality of the net cages and make transportation difficult; heavy lifting equipment requires high requirements; fixed installations cannot flexibly resist wind and waves
