Large floating type steel structure intelligent fishery breeding net cage suitable for deep and far sea

Abstract

The invention discloses a large floating type steel structure intelligent fishery breeding net cage suitable for a deep and far sea. The large floating type steel structure intelligent fishery breeding net cage comprises a net cage body, a netting, a mooring system, a first upper building structure and a second upper building structure; the net cage body is a steel structure frame, has a cross section of a regular hexagon structure, and is internally provided with bait bins; the netting is attached to the net cage body; a periphery of the net cage body is fixed to a seabed through the mooring system; and the first upper building structure and the second upper building structure are arranged on two sides of a top part of the net cage body respectively, an automatic feeding system, a netting cleaning system and a fish collecting system are arranged in the first upper building structure, and a central control room is arranged in the second upper building structure. The net cage body of the steel structure can effectively resist severe storm waves in deep and far sea areas, labor cost is greatly reduced through an automatic intelligent fishery breeding device carried on the net cage, and profits of deep and far sea fishery breeding are increased.

Description

technical field [0001] The invention relates to the technical field of deep sea fishery culture, in particular to a large-scale floating steel structure intelligent fishery culture cage suitable for deep sea. Background technique [0002] At present, marine fish farming is mainly concentrated in shallow waters near the shore, and HDPE cages are the main cages. Shallow waters near the coast, on the one hand, have limited resources, a high degree of development, and are greatly affected by human activities. The water quality of the seawater is relatively poor, and fish breeding species are limited; , The water exchange rate inside the cage is low, and pollutants are easy to accumulate. The service life of HDPE cages is generally 5-8 years, with poor wind and wave resistance, high volume loss rate of net clothing, and limited volume of surrounding water bodies. Large-scale HDPE cage culture requires a lot of manpower and material resources. The resources in the deep sea are m...
