Single-point anchoring type round deep water net cage

Abstract

The invention discloses a single-point anchoring type round deep water net cage. The net cage comprises a framework system, a single-point anchoring system and a netting system. The single-point anchoring system comprises a rope set and an anchoring mechanism, the framework system is provided with a round floating pipe framework, and the netting system is hung on the round floating pipe framework. The net cage is characterized in that the framework system is further provided with an A-like-shaped auxiliary floating pipe framework formed by connecting flowing pipes, the ends, connected with each other, of two bevel edges of the A-like-shaped auxiliary floating pipe framework serve as cage tying points of the framework system, the other ends of the two bevel edges of the A-like-shaped auxiliary floating pipe framework are connected with the round floating pipe framework through a first connection rope and a second connection rope, and the center of a transverse edge of the A-like-shaped auxiliary floating pipe framework is connected with the round floating pipe framework through a third connection rope. By means of the net cage, the round floating pipe framework is not likely to deform or be broken or damaged, and the net cage accords with work features of a single-point anchoring mode.

Description

technical field [0001] The invention relates to a single-point mooring type circular deep-water net cage. Background technique [0002] The breeding cage is composed of four parts: cage frame system, net clothing system, mooring system and supporting facilities system. Wherein the mooring system is the foundation of the cage in the water, once the mooring fixing system has problems in windy and wave weather, it will cause the whole cage to be damaged due to uneven stress. At present, there are three common forms of cage mooring at home and abroad: one is the traditional multi-point mooring of a single cage; The traditional multi-point mooring system is simple in form. At present, this method is mostly used in coastal floating deep-water cages in my country. In multi-point mooring, there are also three types of anchors according to different sea areas. One is pile anchors, mostly wood, and the price is relatively cheap, suitable for shallow water and sandy bottom sea areas;...

Problems solved by technology

[0004] The above-mentioned existing single-point mooring system has the following problems: From an economic point of view, it is necessary to limit the breeding area occupied by the deep-water cages under the anchorage of the single-point mooring system, so the rope group cannot be too long, which makes the tension The angle between the rope group and the horizontal plane in the state is relatively large, so that the upward vertical component of the force exerted by the rope group on the iron anchor is correspondingly relatively large, and the structural characteristics of the iron anchor determine that the anchor tip hooks the seabed. The gripping force is mainly reflected in the horizontal direction, and the larger vertical component of the upward force will make the anchor easily pulled up and out of the seabed under severe sea conditions such as typhoon, causing the anchor as the anchor point to leave its original position. Cause the frame system to deviate from the original breeding area and may collide with deep-water cages in other farming areas or fixed objects in other sea areas

[0005] In the prior art, the circular floating tube frame is the most widely used and the most mature frame system in aquaculture cages, but the circular floating tube frame adopts the single-point mooring method for anchoring, and there are the following problems: due to the single-point mooring system characteristics, the force of the rope group in the single-point mooring system on the circular floating tube frame is mainly the normal force, and the force is concentrated on one point of the circular floating tube frame, which makes it easy to form a single-point mooring system Deformation and breaking damage
