Portion, and interior rack and outer rack are fixed by central support shaft, and the form of interior rack and the combination of outer rack is arranged, and constitute the double-deck knot
The net cage of structure, by fish culture in interior and in the interior net cage being made of interior rack and interior etting, and using outer etting to water flow
It is buffered, steady living environment needed for meeting fish habitat life；In being separately installed on the interior rack and outer rack
Etting and outer etting, and its mesh aperture of interior etting is greater than its mesh aperture of outer etting, the form combined using size mesh is protected
Sufficient water flow exchange has been demonstrate,proved, and has conveniently been ingested, bait has been reduced and is lost；The central support shaft both ends are connected with for controlling net
The floating drum of case sink-float；It is provided with air inlet pipe and discharge outlet on the floating drum, by intake and exhaust pipeline system to aeration of float or note
Water to control sinking floating net cage so that net cage in strong wind weather dive to underwater, hide the attack of stormy waves；The outer rack periphery can
Disassembly is equipped with the spindle for controlling net cage overturning, by adjusting the spindle hanging position of outer rack periphery, so that net cage is whole
Body can generate rotating torque by axle center of central support posts, reach rotation purpose, can periodically overturn in daily breeding production
The outer etting in part and interior etting are exposed on the water surface, enable the microorganism being attached on etting in the exposure of sunlight by net cage
It shines lower dead and falls off, also etting is washed away using cleaning device, convenient for the cleaning of etting, improves Fish Survival ring
Fish survival rate is improved in border；The wing for feedstuff feeding is arranged at intervals on the interior etting；The wing one end with it is interior
Etting connection, the other end pass through outer etting and expose；The wing its be exposed to outer etting one end and be connected with for tightening net
The rope of sleeve；The central support shaft both ends are connected with anchor ingot by anchor chain.
Further, the interior rack is the steel framework of the hexagonal structure of two end sections.
Further, the outer rack is the steel framework of the arc-shaped structure in both ends.
As preferred embodiment, 120 ° are provided with a wing on the interior etting.
Further, valve is installed in the discharge outlet.
Compared with prior art, the offshore aquaculture net cage of the utility model, is arranged interior rack and outer net
The form of frame combination, constitutes the net cage of double-layer structure, by fish culture in interior and in the Intranet being made of interior rack and interior etting
In case, and water flow is buffered using outer etting, steady living environment needed for meeting fish habitat life；And use size
The form of mesh combination ensure that sufficient water flow exchange, and conveniently ingest, and reduces bait and is lost；It can be to aeration of float or note
Water can hide the attack of stormy waves in strong wind weather dive under water to control sinking floating net cage；By the ingot for adjusting outer rack periphery
Sub- hanging position reaches rotation purpose so that net cage integrally can generate rotating torque by axle center of central support posts, can be in day
Net cage is periodically overturn in normal breeding production, the outer etting in part and interior etting are exposed on the water surface, so that being attached on etting
Microorganism can be dead under the exposure of sunlight and falls off, and also washes away using cleaning device to etting, convenient for etting
Cleaning improves Fish Survival environment, improves fish survival rate.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the side structure schematic diagram of the utility model.
Each component mark in attached drawing are as follows: rack in 1-, the outer rack of 2-, etting in 3-, the outer etting of 4-, 5- floating drum, 6- spindle,
