Embodiment Construction

[0039] The embodiment of the present application provides a semi-submersible aquaculture net cage to solve the technical problems of poor wind and wave resistance, small aquaculture volume, poor structural stability, and great influence of water flow velocity in the deep water aquaculture net cage in the prior art; The structural strength is stable and the technical effect of maintaining the breeding volume is maintained.

[0040] In order to solve the above technical problems, the general idea of ​​the technical solution provided by the embodiment of the present application is as follows:

[0041] By establishing the main column, the secondary column and the central column, a concentrated force-bearing structure in the middle is established to form a stable frame structure; the structural stability is greatly improved, and the center of gravity is concentrated on the central column, which can improve the stability of the frame posture; based on With good structural stability,...

Abstract

The invention belongs to the technical field of maritime engineering equipment, and discloses a semisubmersible aquaculture net cage, comprising an underwater floating body, a center upright column, main upright columns, secondary upright columns, surrounding pull rods and a fishing net, wherein two or more main upright columns are fixed on the underwater floating body, surround the center upright column in the middle, and are connected by virtue of supporting rods; two or more secondary upright columns surround the center upright columns in the middle, and are connected with the center upright columns by virtue of the supporting rods respectively; the main upright columns are connected with the main upright columns or the secondary upright columns on the two sides respectively by virtue of the surrounding pull rods; the secondary upright columns are connected with the main upright columns or the secondary upright columns on the two sides respectively by virtue of the surrounding pull rods; and the fishing net is spread out in the space surrounded by the main upright columns, the secondary upright columns and the surrounding pull rods, and is fixed on the main upright columns, the secondary upright columns and the surrounding pull rods. The net cage provided by the invention is strong in stormy wave resistance and strong in aquaculture capacity stability.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a semi-submersible culture cage. 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. Contents of the invention [0005] The inv...
