Integrated symmetrical airfoil deep-water cage culture system

Abstract

The invention discloses an integrated symmetric wing type deep water cage culture system. Deep water cages and a breeding platform are connected integrally, and share the same single-point mooring system. Compared with a system which needs to separately configure mooring systems for the deep water cages and the breeding platform in the prior art, the integrated symmetric wing type deep water cageculture system has the advantages that on the premise of reducing investment cost of the mooring system, breeding space of which the cross surface is in a symmetric wing type can further be formed bythe deep water cages, moreover, the breeding space can further be matched with the single-point mooring system to reduce water flow resistance of the deep water cages in a stable state, and effects ofreducing netting volume loss rate and improving the safety of a frame mooring point structure are achieved; and furthermore, the breeding platform can move along with the deep water cages, thus, thebreeding platform is convenient to use, and function extension is facilitated.

Description

technical field [0001] The invention relates to an integrated symmetrical airfoil-shaped deep-water cage culture system, which belongs to the technical field of marine organism culture devices. Background technique [0002] Most of the deep-water cage culture floating tube frames researched and used at this stage are round and square in shape, and the symmetrical wing-shaped cages with single-point mooring system are specially developed for use in deep and open seas. [0003] As the breeding sea area gradually enters the deep sea, the requirements for various types of farming equipment are getting higher and higher. For example, there is no island base in the deep sea area, which will lead to nowhere to store the breeding feed and various tools and accessories in the breeding process. There is no place to store, no place to rest for breeding practitioners, no place to install various small equipment, etc. The solution to this problem in the prior art is to build another type...

Problems solved by technology

[0003] As the breeding sea area gradually enters the deep sea, the requirements for various types of farming equipment are getting higher and higher. For example, there is no island base in the deep sea area, which will lead to nowhere to store the breeding feed and various tools and accessories in the breeding process. There is no place to store, no place to rest for breeding practitioners, no place to install various small equipment, etc. The solution to this problem in the prior art is to build another type of barge to moor in the deep sea area far away from the coastline all year round, and Due to the high cost and high construction difficulty of the mooring system of the barge, this undoubtedly increases the investment and hinders the development of mariculture to the deep sea to a certain extent.

[0004] Due to the deep sea environment, most of the conditions are high waves and fast currents. Although the symmetrical wing-shaped cages themselves have excellent current resistance or volume retention performance compared to other shaped cages, due to the lack of cultured species at this stage There are no species that can be cultured at high flow rates, so measures need to be taken to reduce the flow field velocity in the cage

The usual method is to arrange breakwaters. However, due to the large area of ​​the breeding sea area and the randomness of the direction of the waves in the outer sea, it is necessary to enclose the entire sea area for breeding with breakwaters. This is undoubtedly a huge investment. The actual operation It's hard to get up
