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

Abstract

The invention discloses a rope-driven rigid-flexible coupled mother-child nested folding ecological breeding cage, which includes a nested foldable mother-child cage frame and has multiple nested folds, that is, the mother frame space folds and longitudinal folds. And the subframe is folded flatly. The nested folding and unfolding cage frame includes a mother-and-daughter frame and a cage folding and unfolding 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 are 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 rope rotates the driving rod to realize the spatial folding and expansion of the main frame; the steel wire rope is connected to the main frame, and the winch retracts and releases the wire rope to fold and unfold longitudinally; the flexible hinge folds and unfolds to fold and unfold the subframe in the plane. The invention has a large folding and unfolding ratio and overcomes the disadvantage of being bulky and inconvenient to transport; the structure has high rigidity; the mother-and-child cage design enables centralized breeding of multiple species and is low in cost.

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
