Top floater type storm-proof deepwater net cage

Abstract

The invention discloses a top floater type storm-proof deepwater net cage. The deepwater net cage comprises an upper end cover, a lower shell and a lifting driving assembly, wherein the upper end cover protrudes outwards to form a hollow umbrella-shaped shell structure, and an electrical bin and a buoyancy bin are formed in the upper end cover; the lower shell is arranged at the bottom of the upper end cover and forms a top shape by surrounding together with the upper end cover; an upper platform, a middle platform and a lower platform are respectively arranged in the lower shell from top to bottom so as to divide the inside of the lower shell into a net cage bin, a hydraulic bin and an oil tank bin; the side wall of the net cage bin is hollow, and a deepwater net cage is placed in the side wall of the net cage bin; and the lifting driving system is used for collecting sea stormy wave signals and driving the net cage to ascend or descend along the inside of the net cage bin according to the sea stormy wave signals. According to the top floater type storm-proof deepwater net cage, a distribution water layer of the deepwater net cage can be flexibly adjusted so as to be accordant with cultivation demands of different types of fishes, and the deepwater net cage can sink under an extreme sea condition, so that the disaster loss is avoided.

Description

technical field [0001] The invention relates to the technical field of deep-sea fish farming, in particular to a gyro-buoy type anti-wind and wave deep-water net cage. Background technique [0002] my country's vast sea area, long coastline and numerous islands promote the vigorous development of aquaculture along the coast. In recent years, due to overfishing by fishermen, the coast has faced a state of no fish to catch; coupled with the increase in the number of near-shore aquaculture, the pollution of the sea area has increased, and the quality of fish has declined, prompting the commercial impact of inshore mariculture, and its survival. The space is reduced. Therefore, from the perspective of sustainable development, the development of marine fishery will shift from fishing to farming, and its key technology lies in the development of deep-water cage technology, which has become the consensus of all countries in the world. [0003] Deep-water cage culture is a new met...
