Large-scale marine lift-type anti-storm-wave cage aquiculture system

Abstract

The invention provides a large-scale marine lift-type anti-storm-wave cage aquiculture system which can automatically go up and down, and has relatively-high anti-storm-wave capability, a relatively-stable frame structure and a relatively-long service life, and is not liable to deform when being used in ocean current. The large-scale marine lift-type anti-storm-wave cage aquiculture system is characterized in that the system comprises vertical-type floating drums (1), a net hauling device (2), netting (3), a stay rope (4), a peripheral framework (5) and a buoyancy adjusting device (6). A plurality of vertical-type floating drums (1) are arranged, and are uniformly installed on the peripheral framework (5) through coaxial sleeve structures; the netting (3) covers the peripheral framework (5); the stay rope (4) is connected with the netting; the net hauling device (2) is connected with the top of the peripheral framework (5); and the buoyancy adjusting device (6) is installed on the peripheral framework (5).

Description

technical field [0001] The invention relates to a marine breeding system, in particular to a large-scale ocean lifting type anti-wind and wave cage breeding system. Background technique [0002] The executive meeting of the State Council on February 6, 2013 pointed out that promoting the sustainable and healthy development of marine fisheries is of great significance for effectively ensuring the supply of aquatic products, increasing fishermen's income, promoting economic development in coastal areas, and safeguarding my country's marine rights and interests. On September 16, 2012, the State Council issued the "Twelfth Five-Year Plan for National Marine Economic Development". The conversion rate of marine scientific and technological achievements has reached more than 50%. On May 11, 2012, the Ministry of Finance and the State Oceanic Administration issued the "Notice on Promoting the Regional Demonstration of Marine Economic Innovation and Development" decision, focusing o...

AI Technical Summary

Problems solved by technology

The applicant of the patent of the present invention has found in practice that the cage culture system in the prior art has the following deficiencies: 1. The cage cannot be lifted and lowered automatically, and the ability to resist wind and waves is not strong

2. The frame structure of the cage is unstable, the service life is short, and the use is unsafe

3. Net clothes are easily deformed under the impact of ocean currents
