[0019] Please see Figure 1-4 This utility model provides a technical solution: an oxygenation device for improving the survival rate of bream, comprising a float 1, with a jet oxygenation nozzle 6 inside the float 1, the input end of the jet oxygenation nozzle 6 being fixedly connected to a first air supply hose 7, an annular aeration pipe 3 connected to the bottom surface of the float 1, annularly arranged aeration risers 31 fixedly connected to the bottom surface of the annular aeration pipe 3, a set of aeration nozzles 32 fixedly connected to the outer surface of each aeration riser 31, a second air supply hose 33 fixedly connected to the input end of the annular aeration pipe 3, a mounting bracket 2 on the right side of the float 1, a high-pressure air supply pump 10 connected to the left side of the mounting bracket 2, a three-way air pipe 8 fixedly connected to the output end of the high-pressure air supply pump 10, the two output ends of the three-way air pipe 8 being fixedly connected to the input ends of the first air supply hose 7 and the second air supply hose 33 respectively, a regulating air valve 9 fixedly connected to the outer surface of the three-way air pipe 8, and an annularly arranged dissolved oxygen sensor 4 on the outer side of the float 1.

[0020] The right side of the mounting bracket 2 is connected to an intelligent controller 17. The intelligent controller 17 is electrically connected to the dissolved oxygen sensor 4 and the high-pressure air supply pump 10 through wires, which can intelligently control the oxygenation device and facilitate effective oxygenation of the aquaculture water.

[0021] The mounting bracket 2 has a protective shell 11 connected to its right side. The intelligent controller 17 is located inside the protective shell 11. A set of heat dissipation holes 12 are provided on both the front and back of the protective shell 11. An alarm 13 is connected to the upper surface of the protective shell 11. The intelligent controller 17 is electrically connected to the alarm 13 through a wire, which can trigger an alarm when there is a lack of oxygen, thus facilitating the effective oxygenation of the aquaculture water.

[0022] The mounting bracket 2 has two mounting legs 14 connected to its bottom surface. Each mounting leg 14 has two mounting plates 15 connected to its outer surface. Each mounting plate 15 has mounting holes 151 on its upper surface, which can be used to install and fix the mounting bracket 2, so as to facilitate the stable use of the high-pressure air pump 10.

[0025] Working Principle: In use, the oxygenation device is first placed in the aquaculture area. The device is then supported by floats 1 and 5, and secured with ropes. When oxygenating the aquaculture water, the intelligent controller 17 controls the high-pressure air pump 10 to generate high-pressure airflow. The high-pressure airflow then enters the annular aeration pipe 3 through the three-way air pipe 8 and the second air delivery hose 33. Compressed air is released into the water as tiny bubbles through the aeration riser 31 and aeration nozzles 32. These bubbles fully contact the water as they rise, dissolving oxygen. Simultaneously, the high-pressure airflow is sprayed at high speed into the water through the jet aeration nozzles 6, creating strong splashes and currents, further promoting air-water mixing and improving the oxygenation effect. Based on data from the dissolved oxygen sensor 4, the intelligent controller 17 automatically adjusts the operating status of the high-pressure air pump 10 and controls the opening and closing of the regulating valve 9 to ensure the dissolved oxygen level in the water remains stable within a suitable range, achieving effective oxygenation of the aquaculture water.
