Anti-storm elbow for deepwater net cage

Abstract

The invention aims to provide an anti-storm elbow for a deepwater net cage, aiming at solving a series of problems that the corners of a polygonal or square net cage in the prior art are broken when stormy waves come and the like due to stress concentration at the corners of the polygonal or square net cage, so that the overall anti-storm capacity of the net cage with a square or polygonal structure is improved. The anti-storm elbowfor the deepwater net cage is produced by dividing the elbow into two parts, and each part comprises a main body, a partition plate, a steel sheet, a steel wire rope, a lifting ring screw, a lifting ring nut, a screw, a nut, a rubber pad and an aluminum sleeve. The main body and the partition plate are made of a high-density polyethylene material and are integrally formed in an injection molding machine through an injection molding process. The two parts are connected into a flexible whole through a spring. The anti-storm elbow for the square net cage is a flexible connecting body, and when the net cage encounters storm waves, the flexible connecting elbow can enable floating pipes around the net cage to swing and fluctuate along with the storm waves within a certain range, so that the storm force of typhoon to the net cage is eliminated to a certain extent, the direct action of large waves and wind force to the net cage is relieved, and the anti-storm capacity of the net cage is improved.

Description

technical field [0001] The invention relates to an anti-wind and wave elbow for a deep-water net cage, belonging to the technical field of deep-water net cages. Background technique [0002] Large-scale marine cage culture is a new breeding technology developed in recent years. Modern science and technology provide scientific and technological means for the development of large-scale cage projects. At present, the types of large-scale cages in the world include HDPE round cages and TCL tension frame cages in Norway, OST dish cages in the United States, FARMOCEAN cages in Sweden, offshore platform cages in the United States, boat-shaped cages, floating cages in Japan There are nearly 10 kinds of rope cages. Although these net cages have the advantages of good performance and large breeding capacity, they require relatively high preparation technology, difficulty in installation and laying at sea, especially the high cost of the system and high maintenance costs, which limit ...
