Lifting net box with inner liner and lifting support system of lifting net box

Abstract

The invention relates to a lifting net box with an inner liner and a lifting support system of the lifting net box. The invention consists of two parts: the net box with the lifting function and the lifting support system, wherein the net box is provided with the telescopic inner liner and mainly comprises a floating pipe, the inner liner, a separation plate, a ventilation main pipe, a ventilation hose, an air distribution pipe, a water communication pipe, a safety cap and the like, and the lifting support system mainly comprises an air pump, a communication pipe, an exhaust pipe, a valve, a flow rate distributor, an air distribution joint and an air pressure meter. The lifting support system on the sea level is connected to the ventilation main pipe through the ventilation hose and is then connected to the inner liner arranged in the floating pipe of the net box through the air distribution pipe, the inner liner can expand and contact under the effect of the air pump, a water body in the floating pipe is discharged when the inner liner expands, the upward floating of the net box is realized, the water body outside the net box enters the floating pipe from the water communication pipe through the siphon effect when the inner liner contacts, the downward sinking of the net box is realized, and the downward sinking is automatically stopped when the net box sinks down to a degree that a sinking element suspended at the bottom of a fishing net is in contact with the sea bed.

Description

technical field [0001] The invention relates to a deep-water net cage lifting control technology in the field of marine aquaculture, in particular to a new type of deep-water net cage with a lifting function and a lifting support system. Background technique [0002] Cage aquaculture is a high-tech aquaculture industry developed in recent years. It uses mesh to assemble a certain shape of the box, set it in a larger water body, and exchange the water inside and outside the cage through the mesh to make the inside of the cage. Form a living water environment suitable for fish life, with the characteristics of high yield, high benefit and high investment. At present, marine aquaculture cages tend to be large-scale, and the aquaculture sea area is developing from shallow waters in inner bays to deep waters above 20m. However, in the deep sea area, the sea surface is strong and the sea current is strong, which seriously threatens the production safety of the cage culture indust...

Problems solved by technology

[0006] Aiming at the deficiencies of the existing net cage lifting technology, the present invention proposes a lifting net cage with a liner and its lifting support system that can solve the above technical problems. By setting a retractable inner liner, the water intake is realized by using the principle of siphon The lifting of the cage; by setting the flow distributor to make the gas distribution even, and there is no seawater corrosion and other problems
