Problems solved by technology

However, in practical application, there are also some defects: (1) the cost of using special HDPE material as the skeleton is high, and it is difficult to popularize in a large area; (2) the settlement is unbalanced, and the net cage is prone to tilt when it sinks, causing fish schools to scurry around (3) It adopts a tubular structure to inflate and drain water, and it needs to be inflated by a boat with an air compressor, which is inconvenient to use; (4) The force-bearing cross-sectional area impacted by seawater is large; (5) The support is not conducive to people walking on it. It is inconvenient and safe to operate on it

Abstract

The tank-type float-sink deepwater net cage includes internal ring, external ring, top ring, net bottom ring, support, air storage tank, float-sink tank high-pressure flexible pipe, low-pressure flexible pipe, compensating pipe, air intake valve, air exhaust value, communicating valve, safety valve, cover net and barrel net, in which the internal ring, external ring and top ring are fixed by means of several supports and formed into upper frame of the net cage; several air storage tanks and float-sink tanks are distributed on the periphery of the upper frame, all the air storage tanks are communicated with high-pressure pipe connected with high-pressure flexible pipe, air intake valve and communicating valve, the float-sink tanks are connected with air pipe whose one end is connected withlow-pressure flexibel pipe, air exhaust valve and communicating valve.

Description

[technical field] [0001] The invention relates to a deep-water net cage, in particular to a tank-type floating-sink deep-water net cage resistant to wind and waves. [Background technique] [0002] Cage fish farming is the most important method of marine aquaculture and has very broad development prospects. Traditional net cages have a simple structure, and the frame is mainly made of wood and other materials. They have poor wind and wave resistance, small scale, and short service life. They can only be installed in inner bays and near shores, which affects the development of mariculture. Research and development of new cages, the development of fish culture in deep-water cages, and the use of high-tech to transform traditional cages have become urgent. Zhejiang Ocean University undertook the project included in the national "863" plan, the key project of Zhejiang Province's scientific and technological development of the sea "Research on large-scale anti-wave deep-water net...
