Problems solved by technology

Breeding net cages are easily deformed under the impact of strong currents, resulting in a greatly reduced culture volume
On the other hand, it is also difficult for breeding objects to resist the continuous impact of water flow above 1.0 m / s for a long time, which can easily lead to fatigue death

Abstract

The invention belongs to the technical field of cultivation net cage equipment, and relates to a sea water flow dividing speed reduction type cultivation net cage which includes a sea water flow dividing assembly. The sea water flow dividing assembly includes an upper polygonal ring plate, a lower polygonal ring plate and a ring-shaped rod. The upper polygonal ring plate is provided with an uppernet frame, the upper net frame is provided with an external net, and a plurality of connecting rods are arranged among the upper polygonal ring plate, the lower polygonal ring plate and the ring-shaped rod correspondingly. Flow guide tubes are fixedly arranged between every two adjacent connecting rods, flow guide channels are arranged in the flow guide tubes, the small ends of the flow guide tubes are away from the ring-shaped rod, and the large ends of the flow guide tubes are close to the ring-shaped rod. The lower polygonal ring plate is provided with baffles corresponding to the small ends of the flow guide tubes, and copper nets are arranged between the upper polygonal ring plate and the ring-shaped rod as well as the lower polygonal ring plate and the ring-shaped rod. A buoyancy mechanism capable of providing buoyancy is arranged between the upper polygonal ring plate and the lower polygonal ring plate, and a bottom net is arranged on the lower polygonal ring plate. The sea water flow dividing speed reduction type cultivation net cage has the advantages of effectively reducing the fluctuation of a water body in the culture net cage and reducing the flow velocity of the waterin the culture net cage.

Description

technical field [0001] The invention belongs to the technical field of aquaculture net cage equipment, and relates to a seawater diversion deceleration type aquaculture net cage. Background technique [0002] Due to the advantages of low cost, high yield, convenient management and high return rate of cage culture, cage culture has developed rapidly in coastal areas in recent years. [0003] In the open sea area without shelter, the tidal current is strong. For example, the characteristic flow velocity in the open sea area of ​​the East China Sea can reach more than 1.0 m / s, and some areas can reach 1.5 m / s. The culture net cage is easily deformed under the impact of strong current, resulting in a greatly reduced culture volume. On the other hand, it is also difficult for the breeding objects to resist the continuous impact of the water flow above 1.0 m / s for a long time, which can easily lead to death from fatigue. Contents of the invention [0004] The purpose of the pr...
