Self-reducing flow low-shape change off land deep water net cage

Abstract

The invention discloses an automatic reducing low-deformation offshore deep-water cage, relating to a cage for marine aquiculture. The invention is capable to reduce the deformation of the cage and the flow rate of the sea water inside the cage. The invention comprises a buoyancy frame, a cage, a sinking ring, a sinking block and an anchoring rope. A supporting and lifting control ring bigger than the buoyancy frame and the diameter of the sinking ring is arranged at the one second depth of the cylindrical cage; a water inlet and a water outlet are arranged in the pipe wall of the supporting and lifting control ring; a girdle rubber inner bag which regulates the lifting and descending of the cage is arranged in the ring pipe; an air-valve is installed in the rubber inner bag and connectedwith the air supply by a pressure hose; between the outer ring and the supporting and lifting control ring of the double-ring buoyancy frame, the bottom outline of the cylindrical cage and the bottomsinking ring, a plurality of flexible ropes are located and connected according to the ring at geometric proportion, and a netting is arranged among the connecting ropes of the three rings; and finally, a flexibly connected automatic reducing low-deformation offshore deep-water cage with a cylindrical inside and a two-cone platform outside is formed, the stress point of the anchoring rope of the cage is arranged at the supporting and lifting control ring.

Description

technical field

[0001] The invention relates to a marine culture net cage, especially an offshore deep water anti-wind and wave net cage. Background technique

[0002] According to the application number 200410075404.3 published on June 14, 2006 by the State Intellectual Property Office of the People's Republic of China, the application number 200410075404.3, the description of the invention title "Asymmetric double-cone sinking and floating anti-wind and wave current net cage", the net cage "1. Effectively overcome the impact of sea currents against wind and waves on the net cage. 2. The double sinking and floating function can greatly simplify management difficulty and labor intensity.", but the manual does not disclose the actual information about whether the net cage is successfully applied.

[0003] At present, the representative deep-water cages that have been used in aquaculture production are as follows:

[0004] The forms of offshore deep-water anti-wind and wave n...
