Tension type sit-on-bottom net cage

Abstract

The invention provides a tension type sit-on-bottom net cage suitable for bottom water body culture. The net cage connects a basic frame at the bottom of the net cage with a tension floating frame atthe upper part of the net cage through a flexible tension cable and a net body to form a flexible net cage with an integral buffer system. The net cage has strong wind and wave resistance capability,meanwhile, the volume retention rate of the net cage is improved, and the requirements of berthing and breeding operations are met.

Description

technical field [0001] The invention relates to a net cage device for underwater culture, in particular to a net cage of a tensioned bottom type. Background technique [0002] The development of marine ranching is inseparable from deep-sea cage culture equipment. Deep-sea cage culture equipment involves many engineering issues such as the anti-wave performance of the cage, bait feeding, net cleaning, monitoring and operation convenience. In deep waters, the wind and waves are generally larger. In particular, the East my country Sea and the South China Sea are located in typhoon-prone areas, and the impact of wind and waves on the cage culture system is particularly obvious. The development of deep-sea cages is that Norway, the United States, and Japan are at the forefront of the world. [0003] The main forms of cages in Norway are cylindrical cages made of HDPE and sinkable tension leg cages. The advantages of cylindrical cages are low cost, simple structure, and conveni...

Problems solved by technology

At present, the biggest disadvantages of deep-water cages in my country are poor wave resistance and current resistance. The water flow environment in the cages is not suitable for fish farming, and there is a lack of supporting technology and facilities.
