A seawater flow deceleration type aquaculture cage

Abstract

The invention belongs to the technical field of aquaculture net cage equipment, and relates to a seawater diversion deceleration type aquaculture net cage. The present invention includes a seawater diversion assembly, which 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 upper frame, the upper frame is provided with an outer net, the upper polygonal ring plate, and the lower multilateral ring plate A number of connecting rods are respectively arranged between the ring rod and two adjacent connecting rods; a diversion tube is fixed between two adjacent connecting rods, and there is a diversion channel in the diversion tube. The small end of the diversion tube is far away from the ring rod, and the guide tube The large end of the tube is close to the ring rod; the lower polygonal ring plate is provided with a baffle corresponding to the small end of the diversion tube; between the upper polygonal ring plate and the ring rod, and between the lower polygonal ring plate and the ring rod A copper mesh is provided; a buoyancy mechanism capable of providing buoyancy is provided between the upper multilateral ring plate and the lower multilateral ring plate; a bottom net is arranged on the lower multilateral ring plate. The invention has the advantages of effectively reducing the fluctuation of the water body in the culture net cage and reducing the water flow velocity in 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...
