Multifunctional deep water cage system

Abstract

The invention discloses a multifunctional deep water net cage system. The multifunctional deep water net cage system comprises an anchoring foundation, anchor chains, a floating pipe frame, netting and sinkers. The tubular netting is installed on the lower end face of the floating pipe frame, the sinkers are suspended at the lower end of the netting at intervals, and multiple columns of longitudinally distributed sleeves are arranged around the netting. Cage-shaped elastic joints are further included, the cage-shaped elastic joints are formed by welding ellipsoidal elastic fan pieces at the two ends according to axial symmetry distribution, and a mooring ring is arranged on the convex surface of the center of symmetry of the two ends of each cage-shaped elastic joint. The anchor chains comprise the main anchor chain and the auxiliary anchor chains, the cage-shaped elastic joints are connected to the main anchor chain at intervals, one end of the main anchor chain is moored on the anchoring foundation, and the other end of the main anchor chain is moored on a connecting ring. After the auxiliary anchor chains penetrate through the columns of sleeves, one end of each auxiliary anchor chain is moored on the floating pipe frame, the other end of each auxiliary anchor chain is moored on the connecting ring, and fixing frames located below the netting are bound at the corresponding positions of the auxiliary anchor chains. A single-point anchoring mode is adopted, the netting can be fixed, and the anchor chains have a power buffering function.

Description

Technical field:

[0001] The present invention relates to seawater culture net cages, and more particularly relates to a multifunctional deep-water net cage system. Background technique:

[0002] The sea area within the 20 m isobath in my country is about 16 million hectares, and the sea area within the 40 m isobath is about 50 million hectares. There is a huge space for the development of mariculture. Vigorously developing deep-water cage culture with a water depth of more than 20 m, obtaining resources from the ocean, expanding living space, developing "marine pastures" and establishing "sea granaries" are one of the new ways to solve the problem of food supply security in my country.

[0003] The deep-water cage industry is one of the important innovative industries for my country's fishery to move towards a modern fishery. Aquaculture cages are generally composed of four parts: cage frame system, net clothing system, mooring system and supporting facilities system. Rega...
