Automatic lifting floating type integrated flexible net cage

Abstract

The invention relates to an automatic lifting floating type integrated flexible net cage. The integrated flexible net cage comprises an upper floating frame assembly; the upper floating frame assemblyis of a circular or polygonal rigid structure and floats on water surface through a floating body; multiple automatic lifting devices are arranged at different positions of the upper floating frame assembly and include mounting brackets, winch wheels arranged on the mounting brackets and motors, the winch wheels are wrapped with pulling ropes, and output shafts of the motors are coaxially connected with the winch wheels; the lower ends of the pulling ropes are connected with connecting ropes, the connecting ropes are fixedly connected to a purse seine, and the purse seine is of a flexible structure; the purse seine is fixedly connected with a lower supporting assembly, the lower portion of the lower supporting assembly is connected with an anchor, and the anchor sinks into the bottom of awater body. The adoption of the automatic lifting floating type flexible net cage, on the one hand, can buffer the rigid impact of waves, and on the other hand, can solve disasters caused by bad seaconditions to aquaculture by lifting the purse seine. At the same time, the manufacturing cost of the net cage is reduced, and the mechanical automatic lifting solves the problems of deep sea super large flexible net cages.

Description

technical field [0001] The invention relates to an automatic lifting and floating integrated flexible net cage, which belongs to the technical field of lifting farming net cages. Background technique [0002] Large-scale deep-water anti-wind and wave cage culture has various forms. It is a new type of cage culture technology that has developed rapidly in the world in recent years. It generally consists of seabed fixation, cage frame, high-strength cage, underwater monitoring, automatic feeding, automatic It is composed of fish harvesting and other facilities. [0003] Deep-water cage culture can be divided into three types: floating type, lifting type and sinking type according to its working mode. Floating cages: generally set in semi-open sea areas with good water quality, water depth of more than 15m, flow velocity less than 1m / s and waves up to about 5m. Lifting net cage: usually floats on the sea surface, sinks 8-10m underwater when the environment in the breeding sea...

AI Technical Summary

Problems solved by technology

Submerged net cage: it can be set in a completely open sea area, and does not reject any wind and waves, but it is expensive, has a high degree of automation, and requires complete supporting facilities

[0004] The existing lift-type cages have the following problems: 1. The overall structure is rigid, and the lifting of the cage is adjusted by adjusting the amount of air inflated by the floating body. However, the deep-sea cages tend to be large-scale and require high strength to meet the requirements of strong wind resistance , so the requirements for the strength of the cage are very high, resulting in a higher cost of the cage; however, due to the high risk of breeding, the high cost of equipment further increases the risk of breeding, which has a greater impact on the economic risk of farmers

2. The adjustment of cage lifting is inconvenient, and the degree of automation is low, which is not conducive to large-scale farming
