Variable-volume deep-sea butterfly-shaped net cage and regulation and control method thereof

Abstract

The invention discloses a variable-volume deep-sea butterfly-shaped net cage and a regulation and control method thereof. A central column sequentially penetrates through the middles of an upper butterfly-shaped net cage and a lower butterfly-shaped net cage, the upper butterfly-shaped net cage and the lower butterfly-shaped net cage are symmetrically arranged, the opposite ends of the upper butterfly-shaped net cage and the lower butterfly-shaped net cage are connected to the end parts of the central column through an upper flange plate and a lower flange plate respectively, the opposite ends of the upper butterfly-shaped net cage and the lower butterfly-shaped net cage are rotationally connected to the middle of the central column correspondingly, the periphery is connected through multiple pins, the upper flange plate and the lower flange plate are correspondingly connected to a signal collector, an underwater power generation traction platform is connected to the lower flange plate, a control system is installed on the underwater power generation traction platform and is in signal connection with the underwater power generation traction platform, and the upper butterfly-shaped net cage, the lower butterfly-shaped net cage and the signal collector are correspondingly in signal connection with the underwater power generation traction platform and the control system. According to the variable-volume deep-sea butterfly-shaped net cage and the regulation and control method thereof, damage caused by collision among rod pieces due to impact force of wave motion can be effectively avoided, a large amount of labor force can be saved, safety accidents caused by underwater work of workers in a severe environment are avoided, and response can be made in time in the sudden change environment, and damage to the net cages is avoided.

Description

technical field [0001] The invention relates to the field of deep-sea aquaculture, in particular to a variable-volume deep-sea butterfly net cage and a control method thereof. Background technique [0002] With the continuous improvement of people's living standards, the demand for marine aquatic resources continues to increase. As a healthy food, fresh aquatic products have become one of the first-selected varieties for large, medium and small cities, restaurants and the general public. It is impossible to meet the market's demand for seafood by relying on natural fishing methods alone, nor can it guarantee the sustainable development of marine fisheries. Therefore, countries all over the world (especially offshore countries with rich marine resources) have begun to study and enter the field of deep-sea cage culture, and open up a new modern low-carbon and environmentally friendly artificial marine pasture. [0003] Most of the net cages used in traditional farming in my c...

Problems solved by technology

The above inventions solve various problems of deep-sea net cages, but the modular splicing only realizes modularization, which cannot reduce the volume and increase the transportation cost; most of the functions of net cage submersion and lifting are realized by changing the self-weight Or buoyancy to adjust, this method is difficult to make the cage suspended in the desired underwater depth, only when the buoyancy is exactly equal to gravity can be suspended, this balance is easily damaged by various factors, resulting in unstable suspension; When encountering a storm, most of the cage support connections are rigid connections, because the impact of wind and waves will accelerate fatigue damage
