A water inlet 11 for injecting water into the cavity of the outer tube is arranged on the side wall of the outer tube 1 near one end of the outer tube plug; the water inlet is communicated with the water pump through the pipeline, so that the water pump can inject water into the cavity of the outer tube from the water inlet of the outer tube and jet out from the jet port to form high-speed water jet. The micro-nano bubble assembly 3 is arranged in the cavity of the outer tube 1 and is suspended in the cavity of the outer tube, so that the micro-nano bubble assembly is not contacted with the inner wall of the outer tube. The outer tube of this embodiment is a straight-through UPVC tube.
The micro-nano bubble assembly 3 comprises an air inlet pipe 31 provided with a cone frustum structure, an air inlet pipe plug 32 for sealing and plugging the air inlet pipe and an air permeable membrane pipe 33 for manufacturing micro-nano bubbles; one end of the air inlet pipe 31 passes through the outer pipe plug 2 and then is exposed out of the outer pipe 1, and one end of the air inlet pipe exposed out of the outer pipe is communicated with external air supply equipment through an external air supply pipeline; the other end of the air inlet pipe is suspended in the cavity of the outer pipe 1, and the outer wall of the air inlet pipe is not contacted with the inner wall of the outer pipe.

Because the pore diameter of the air bubble is 0.1 micron, oxygen in the air bubble can be dissolved into the water more easily and quickly, the oxygenation efficiency is increased, the oxygenation efficiency is up to 50% -60%, and the oxygenation dynamic efficiency of the water is up to more than 7 (kgO/kW.h), so that the oxygen content in the water is increased.

In order to better form circulating water flow in the fish pond, the water body flow in the fish pond is accelerated, the energy consumption for manufacturing the circulating water flow is reduced, and the placement position of the micro-nano bubble oxygen increasing gun is designed. The distance from the center of the pond body of the fish culture pond to the air inlet of the micro-nano bubble oxygen increasing gun is designed to be larger than the distance from the center of the pond body of the fish culture pond to the jet port of the micro-nano bubble oxygen increasing gun, namely the jet port of the micro-nano bubble oxygen increasing gun is inclined towards the inside of the fish culture pond, so that three micro-nano bubble water mixed jet streams generated by the micro-nano bubble oxygen increasing gun incline to the center of the fish culture pond to form annular water flow, and the water body in the fish culture pond is pushed and accelerated to flow, thereby driving the groupers in the fish culture pond to move, meeting the life habit of the groupers in liking for good water movement, improving the survival rate, gonad development and disease resistance, reducing the bait coefficient and promoting the growth and development of the groupers. Meanwhile, the angle of the micro-nano bubble oxygen-increasing gun in the breeding fish pond is designed, the distance from the center of the pond body of the breeding fish pond to the air inlet of the micro-nano bubble oxygen-increasing gun is larger than the distance from the center of the pond body of the breeding fish pond to the jet port of the micro-nano bubble oxygen-increasing gun, an included angle exists between water flows emitted by the jet port of the micro-nano bubble oxygen-increasing gun, the flow velocity of the water flows in the breeding fish pond is accelerated, the energy consumption of water circulation water flows generated in the breeding fish pond is reduced, the movement of the groupers is stimulated, the meat quality of the bred groupers is delicious, the growth time and the breeding period of the groupers are shortened, and the nutritive value and the economic value of the groupers are improved.
The working principle of the fish farming device is as follows: in the industrial breeding of the groupers, seawater is pumped into a breeding fish pond, the groupers are placed in the breeding fish pond, and as the density of the groupers in the breeding fish pond is high, a water pump is required to be started, when the water pump works, the seawater in the breeding fish pond is pumped into the filtering device from a water inlet of a filtering device at the central position of the breeding fish pond to be filtered, the seawater filtered by the filtering device flows into a water pump inlet through a pipeline, is accelerated by the water pump, is conveyed to a micro-nano bubble oxygen increasing gun through the pipeline, and is injected into an inner cavity of an outer pipe from a water inlet of the outer pipe; because the pipe diameter of the air inlet pipe arranged in the outer pipe is gradually increased from small to large, when water flow enters the outer pipe, the water flow in the outer pipe is accelerated by the conical frustum inclined surface passing through the air inlet pipe, and the water flow in the outer pipe is accelerated; the air pump is communicated with the air inlet pipe through a pipeline, the air pump conveys air into the air inlet pipe, the air enters the air permeable membrane pipe from the inner pipe under the action of the air inlet pipe plug, the air entering the air permeable membrane pipe is made into micro-nano bubbles by utilizing bubble holes of a heavy ion microporous membrane layer of the air permeable membrane pipe, then overflows from the pipe wall of the air permeable membrane pipe into the outer pipe, the micro-nano bubbles are mixed with high-pressure water flow formed in the outer pipe, high-speed bubble water jet flow is formed in the outer pipe and is ejected from a jet port of the outer pipe, and the high-speed water flow ejected from the jet port pushes and accelerates the sea water flow in the cultured fish pond, so that the groupers in the cultured fish pond are promoted to swim; meanwhile, oxygen in micro-nano bubbles in high-speed aquatic products is dissolved into seawater in a fish culture pond, so that the oxygen content in the seawater is increased, and accordingly the seawater contains uniform and sufficient dissolved oxygen.
The thickness of the heavy ion microporous membrane layer and the pore diameters of the air bubble holes can be realized by selecting any thickness value of the heavy ion microporous membrane layer from 5 to 120 micrometers except that the thickness of the heavy ion microporous membrane layer is 10 micrometers and the pore diameters of the air bubble holes are 0.1 micrometers as described in the above examples, and the implementation modes of the heavy ion microporous membrane layer and the pore diameters of the air bubble holes are similar to those described in the above examples, and are not repeated herein.
