A rope-driven rigid-flexible coupling nested folding ecological breeding cage

Abstract

The invention discloses a rope-driven rigid-flexible coupling nested and folded ecological breeding net cage, which includes a nested folded and expanded child-mother type net cage frame, and has multiple nested folds, that is, the mother frame is space folded and longitudinally folded. And the plane folding of the sub-frame. The nested foldable female cage frame includes a female female frame and a cage folding drive mechanism. The mother frame includes an upper frame and a lower frame, both of which are triple symmetrical Bricard mechanisms with the same size and shape and parallel. The cage drive folding mechanism includes a central column, a sliding seat, a driving rod and a closed-loop rope. The central column is connected to the mother frame through a driving rod. The driving rod is connected to both ends of the closed-loop rope, and the driving rod is rotated by the rope to realize the space folding of the mother frame; the steel wire rope is connected to the mother frame, and the winch retracts and retracts the steel wire rope for longitudinal folding; the flexible hinge folding makes the sub-frame fold and unfold in a plane. The invention has a large folding ratio and overcomes the disadvantage of being bulky and inconvenient for transportation; the structure has high rigidity; the design of the mother-child net cage realizes multi-species centralized breeding, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of marine aquaculture engineering equipment, and relates to a marine ecological aquaculture net cage, in particular to a rope-driven rigid-flexible coupling nested and folded ecological aquaculture net cage. Background technique [0002] Mariculture is an important part of the aquaculture industry. China has a long history of marine aquaculture. Oyster farming was carried out as early as before the Han Dynasty, and the method of cultivating pearls was invented in the Song Dynasty. After the founding of the People's Republic of China, mariculture in my country developed rapidly, especially the development of main economic species such as kelp, seaweed, mussels and prawns, which drove the development of coastal economy and became a major industry in coastal areas. Calculated according to international statistical standards, China has become the largest country in mariculture. [0003] With the progress of th...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects of the prior art that are bulky, fixed in structure, high in use cost, single in division of aquaculture area, and unable to meet the needs of diversified aquaculture of aquatic products, and to provide a product with good foldability, low cost of use, and relatively small division of aquaculture area. Deep-sea aquaculture cages that can meet the diverse needs of aquatic products
