A "diamond" type current-resistant and wind-resistant deep-water culture cage

Abstract

A diamond-shaped wave-resistant and storm-resistant deep-water culture net cage is characterized by comprising a net cage frame system which is composed of an outer floating frame, an inner floating frame, a reinforcement pipe, a 60-degree elbow, 60-120-degree lateral tees, 120-degree elbows and floating frame connecting pieces, a mooring system which is composed of a mooring rope, an anchor chain, an anchorage, a front-end buffer floating ball, middle floating balls, a buffer counter weight and a rear-end buffer floating ball, a net cage flow reduction stable structure which is composed of wave stabilizing plates and front-end flow reduction nettings, and a net bag system which is composed of nettings, ground ropes and a bottom frame. The floating frames are of a diamond-shaped structure, and a multi-section buffer single-point mooring system is adopted by the mooring system, through the diamond-shaped frame structure and the multi-section buffer single point mooring system of a net cage, the top of the net cage directly faces wave currents under the action of the wave currents, and a wave breaking effect is achieved, so that the acting force of the waves to the net cage is reduced, and the Chinese Blue granary strategy implementation and the mariculture development tendency from inshore to deep sea are promoted.

Description

technical field [0001] The invention relates to a current-resistant and wind-wave resistant culture cage, in particular to a "diamond" type current-resistant and wind-wave resistant deep-water culture cage with a single-point mooring system. Background technique [0002] Due to the dwindling of arable land and the scarcity of fresh water resources, the development of freshwater fishery in China has been more and more constrained. At the same time, the space and environmental constraints of inshore mariculture are also becoming more and more obvious. Large-scale mariculture concentrated in a narrow space near the shore and shallow waters will bring about a series of problems such as industrial conflicts, ecological losses, disease risks, and quality and safety. Therefore, it has become an inevitable choice for the development of my country's mariculture industry to expand mariculture from nearshore to offshore and to deep sea. Cage culture is carried out in deep and open sea...

AI Technical Summary

Problems solved by technology

At present, the types of anti-wind and wave cages in my country cannot fully meet the needs of cage culture in deep and high seas. The development of new types of current-resistant and anti-wind and wave cages suitable for deep and deep seas is the technical requirement to promote the development of cage culture in my country from offshore to deep seas.
