Rope-driven rigid-flexible coupling master-slave nested folding type ecological breeding net cage

Abstract

The invention discloses a rope-driven rigid-flexible coupling master-slave nested folding type ecological breeding net cage. The ecological breeding net cage comprises a nested folding and unfolding master-slave nested type net cage frame which has multiple nested folding and unfolding functions including master frame space folding and unfolding, longitudinal folding and unfolding and slave frameplanar folding and unfolding. The nested folding and unfolding master-slave nested type net cage frame comprises a master-slave framework and a net cage folding and unfolding driving mechanism. The master-slave framework comprises an upper-layer framework and a lower-layer framework which are threefold symmetric Bricard mechanisms identical in size and shape and parallel to each other. The net cage folding and unfolding driving mechanism comprises a center stand column, a sliding base, a driving rod and a closed-loop rope, the center stand column is connected with the master framework throughthe driving rod, the driving rod is connected with the two ends of the closed-loop rope, and the rope rotates the driving rod to achieve space folding and unfolding of the master framework; a steel wire rope is connected with the master framework, and a winch winds and unwinds the steel wire rope to achieve longitudinal folding and unfolding; slave framework planar folding and unfolding are achieved through flexible hinge folding and unfolding. The net cage is large in folding and unfolding ratio, and the defects that a net cage is large and inconvenient to transport are overcome; the structure is high in rigidity; the master-slave type net cage is designed to realize centralized breeding of multiple species, 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...
