[0002] The device specifically relates to a cage. Cage culture is a new technology for the development of aquaculture in the world towards intensive production. It has the characteristics of high yield, low cost, long service life, small investment, easy management, land, water and energy saving, and effective development of large surface fisheries in oceans, rivers, lakes and reservoirs. The high-yield principle of cage culture: First, the fish are raised in the cage, the activity is reduced, the breathing rate is reduced, the metabolism is slow, the energy consumption is reduced, which is conducive to the transformation and accumulation of nutrients; second, the net is dried in the sun, the net is not added with drugs to make the net cleaner, the water inside and outside the box is freely exchanged quickly, and sufficient oxygen and natural bait are obtained. Part of the fish excrement is taken out of the box with the water flow, and the rest is recovered by setting a feces and garbage recovery device at the bottom of the net, which is conducive to keeping the water fresh and providing fish with a superior living environment; third, it can avoid the invasion of enemies in the water area on fish and aquatic animals, improve the growth rate and return with safety protection; fourth, different feeds are prepared according to different fish, which is conducive to intensive breeding and high yield and fish disease prevention and control; fifth, the cage is easy to manage, and the adult fish is easy to get out of the water, and the recapture rate is high.

[0003] This technical solution is a further improvement of another invention patent of the applicant, with publication number "CN103385185B" and the name "an assembled deep-sea cage".

[0070] When the first buoyancy tube 21 is a metal tube, the device can be lifted up by increasing the diameter of the first buoyancy tube 21 .

[0071] Working principle: when the device descends, the gas in the device tube body is discharged from the air inlet and outlet by designing gravity, the first switch 12 and the second switch 17 are opened, and water enters the central column 1 and multiple groups of columns 2 from the bottom of the device. When the gravity of the device is greater than the buoyancy, it begins to descend, and the gas is discharged through multiple air inlets and outlets. When the water flow submerges the first support tube 3, the sinking speed of the device is accelerated. In order to control the sinking speed and sinking stability, the water flows through the column 2 or the first support tube 3 into the regulating tube 5, and fills from the lowest end of the regulating tube 5 to the highest end. The regulating tube 5 covers the top of the device and is triangular in shape, so that the device maintains balance when descending; when the device rises, the air inlet and outlet of the device are inflated and drained, so that the buoyancy of the device is greater than the gravity, and the device begins to float until the bottom surface of the device net rises above the water surface. At this time, the entire device net is exposed to the air for easy drying of the entire net.

[0072] Compared with the prior art, the technical solution of the present invention can achieve the following beneficial effects: by setting an adjustment mechanism, the device can be made more stable when descending, solving the serious losses of fry caused by typhoons, and providing a safe environment with good water quality for fish growth; by raising the fry, the fry can be lowered to another net cage underwater, reducing labor, reducing damage to the fry, and not damaging the adult fish when collecting the fish, and the price is high. By setting the top center and the bottom center of the device to protrude outward to form a triangular structure, the water resistance when the device rises or falls can be reduced; by setting a multi-layer buoyancy tube, the device of different heights and weights can be raised; by setting a third partition 27 in the third buoyancy tube, the gravity at the bottom center of the device is increased, which can enhance the stability of the device and enhance its service life; by setting a feces and garbage recycling mechanism 28 to recycle the fish excrement, it is beneficial to keep the water fresh, so that the fish have a superior living environment and are more environmentally friendly.
