Intelligently-controlled and balanced lifting deep sea aquaculture cage

Abstract

The invention relates to an intelligently-controlled and balanced lifting deep sea aquaculture cage and belongs to the field of deep sea intelligent aquaculture equipment. The deep sea aquaculture cage mainly comprises a cage body and an intelligent balanced lifting system. The cage body comprises a high-strength netting, a horizontal frame, fixed cross rods, vertical balance pipes, bottom fixing structures, waterproof exhaust safety valves, airproof drainage safety valves, bottom anchors, mooring rope fixing devices, safety rails and an automatic bait feeding port. The intelligent balanced lifting system comprises cage posture sensors, pressure sensors, water level sensors, outer branch air pipes, inner branch air pipes, an underwater sealed air distribution device, a seawater cable, a water floating wireless controller, a solar power supply device, a total air pipe and an upper computer provided with management software. The deep sea aquaculture cage has the advantages that ascending and descending of the cage are completely intelligent, balanced and controllable, investment of labor cost is reduced, potential safety hazards are reduced for staff, efficiency is high, and the survivability of the cage and animals bred in the cage in deep and far sea is enhanced.

Description

technical field [0001] The invention relates to a deep-sea culture cage with intelligent control of balanced lifting, which belongs to the field of deep-sea intelligent culture equipment. Background technique [0002] The "Twelfth Five-Year Plan" raised the marine economy to the height of the national strategy, marking the beginning of economic development extending from the inland to the ocean, and the blue ocean economy will become the hope of China's development. The development of the marine economy is inseparable from the development of the marine aquaculture industry, and the development of the marine aquaculture industry is inseparable from the development of marine aquaculture equipment. Deep sea intelligent aquaculture equipment is the frontier direction of marine aquaculture equipment development. [0003] At present, marine aquaculture cages are mainly divided into two types, forced floating cages (Norway and Irish cages) and natural exhaust lifting cages. The fo...

Problems solved by technology

[0003] At present, marine aquaculture cages are mainly divided into two types, forced floating cages (Norway and Irish cages) and natural exhaust lifting cages. The forced floating cages float on the sea level all the year round, and can be partially filled with water to sink during typhoons. However, the diving depth is limited, and it is impossible to dive to a safer seabed, and the overall anti-current capability is not strong, about 1.5 knots. The net cage may be intact, but the cultured species (such as fish) in the net cage have nowhere to hide due to the deformation of the net clothing, resulting in a large number of casualties of the cultured species (such as fish); for the lifting net cage controlled by natural exhaust, During the lifting process, it is easy to be affected by environmental factors such as wind, waves and currents, resulting in unbalanced pressure between the buoys, resulting in a difference in the speed of exhaust between the buoys, causing the overall deflection, tilting, and overturning of the cage. The lifting cage in the marine environment is subject to The effect of the above factors and the influence of its own structural characteristics, it is inevitable to produce unbal
