Abstract

The invention belongs to the technical field of ocean engineering devices, and discloses a deep sea aquaculture net cage which comprises an upper building, a central vertical column, a barrel-shaped frame, a supporting rod structure, a ballast tank and a fishing net. The central vertical column is positioned at the center of the barrel-shaped frame and fixed on the barrel-shaped frame through the supporting rod structure, the upper building is fixed at the top end of the central vertical column, the ballast tank is fixed at the lower end of the central vertical column, the barrel-shaped frame comprises a vertical frame and a horizontal frame, the horizontal frame is fixed at the upper end of the vertical frame and fixedly connected with the upper portion of the central vertical column, the lower end of the vertical frame is fixedly connected with the lower portion of the central vertical column through the supporting rod structure, the fishing net is provided with a plurality of fixed nodes, and the fixed nodes are connected with the barrel-shaped frame and the supporting rod structure. The net cage is stable in structural strength and superior in balance performance.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a net cage for deep sea culture. Background technique [0002] The main structure of the existing deep water culture net cage is a gravity type HDPE net cage. [0003] Due to the light structure and low strength of the material, it is mainly installed in nearshore bays or semi-enclosed waters with islands and reefs as barriers. Generally, it can only withstand water flow below 0.5m / s. [0004] Under the water flow of 1m / s, 80% of the breeding capacity will be lost, and limited by the material and structure of HDPE cages, the maximum breeding volume can only be 7400 cubic meters. On the other hand, whenever the deep-water cage culture area is hit by a large wind and wave, the structural stability of the cage will be affected under the attack of waves and currents, and the culture volume will also be greatly lost. In particular, the net cage is very easy to ...
