[0021] Please refer to Figures 1 to 2 , the present invention provides a technical solution: an aerator for fry cultivation ponds, including a mounting frame 1. At the top of the mounting frame 1, there are a plurality of annular aeration pipes 2 with different diameters. A concentric circle structure arranged at intervals is formed between the plurality of annular aeration pipes 2 with different diameters. At the outer top of each annular aeration pipe 2, a plurality of first distribution pipes 5 are vertically provided. The top end of the first distribution pipe 5 is connected to a first fixing cylinder 6, and a nano bubble disk 7 is installed inside the first fixing cylinder 6;

[0022] As Figure 2 shown, the plurality of annular aeration pipes 2 with different diameters are laid from the periphery of the cultivation pond towards the center of the cultivation pond. The nano bubble disks 7 in the first fixing cylinders 6 on each annular aeration pipe 2 will generate a large number of oxygen-containing microbubbles from the bottom of the cultivation pond, thereby enabling more uniform oxygenation, reducing the incidence of local hypoxia, and being beneficial to enhancing the vitality of fry;

[0023] Among them, the nano bubble disk 7 will generate fine and continuous extremely fine bubbles inside the cultivation pond. The micro-nano bubbles have a slow rising speed, a long residence time, and a high dissolution efficiency in water, and will not generate violent rapids in the pond to cause harm to the fry;

[0024] Above the top of the outermost annular aeration pipe 2, there is an oxygen delivery elbow 12. At the outer bottom of the oxygen delivery elbow 12, there is a second distribution pipe 20 corresponding to the annular aeration pipe 2. The bottom end of the second distribution pipe 20 is connected to a rotary joint 13. At the outer top of each annular aeration pipe 2, there is an external thread interface 11 corresponding to the rotary joint 13, and the bottom end of the rotary joint 13 is spirally connected to the external thread interface 11;

[0025] As Figure 2 shown, by setting the rotary joint 13, the external thread interface 11, and the second distribution pipe 20, it is convenient for the disassembly and assembly work between the oxygen delivery elbow 12 and the annular aeration pipe 2;

[0026] It further includes a blower box body 15. One side of the blower box body 15 is connected to the outer wall of the cultivation pond. An air compressor 18 is fixedly installed inside the blower box body 15. The top end of the oxygen delivery elbow 12 penetrates through the blower box body 15 and is connected to the air outlet of the air compressor 18;

[0027] During the actual working process, the air compressor 18 can input air into each annular aeration pipe 2 respectively through the oxygen delivery elbow pipe 12 assembly. After the air is output from the nano-bubble disk 7, a large number of oxygen-containing micro-bubbles will be generated inside the cultivation pond, thereby realizing uniform oxygenation and aeration.

[0028] Furthermore, a maintenance cover plate 16 is hinged on one side of the fan box 15 away from the oxygen delivery elbow pipe 12. The free end of the maintenance cover plate 16 is connected to one side of the fan box 15 through a lock. By setting the maintenance cover plate 16, it is convenient to repair and maintain the air compressor 18 assembly inside the fan box 15, improving the practicality.

[0029] Furthermore, a liquid crystal display screen 17 is fixedly installed on one side of the maintenance cover plate 16, and a water quality detector 14 is fixedly installed on the outside of the oxygen delivery elbow pipe 12. The water quality detector 14 is connected to the liquid crystal display screen 17 through digital display. The water quality detector 14 is used to monitor the water quality data inside the cultivation pond in real time, and the water quality data is then visually displayed to the staff through the liquid crystal display screen 17, facilitating the staff to make adjustments according to the water quality in real time.

A second fixing cylinder 9 is coaxially arranged outside the sealing rubber ring 8. A limiting groove 10 corresponding to the sealing rubber ring 8 is opened on the inner wall of the second fixing cylinder 9. The sealing rubber ring 8 is located inside the limiting groove 10. By setting the sealing rubber ring 8 and the limiting groove 10, the second fixing cylinder 9 can be sleeved outside the first fixing cylinder 6, thereby fixedly installing the nano-bubble disk 7 inside the first fixing cylinder 6, which is convenient to use and easy to operate.

[0031] As Figure 1 shown, an air inlet pipe 19 is connected to the air inlet of the air compressor 18. One end of the air inlet pipe 19 penetrates to the outside of the fan box 15. By setting the air inlet pipe 19, it is convenient for external air to enter the air compressor 18, which is beneficial to the continuous progress of subsequent aeration work.

[0032] Furthermore, a plurality of U-shaped pipe clamps 3 are provided on the outside of each annular aeration pipe 2. The U-shaped pipe clamps 3 are connected to the mounting rack 1 through bolts. By setting the U-shaped pipe clamps 3, it is convenient to fixedly install the annular aeration pipe 2 on the mounting rack 1.

[0033] As Figure 2 shown, a connecting portion 4 is provided at the end of the mounting rack 1. The connecting portion 4 is connected to the inner wall of the cultivation pond through bolts. After the annular aeration pipe 2 is positioned and installed, the staff can fixedly install the mounting rack 1 assembly at the bottom of the cultivation pond through the connecting portion 4 on the mounting rack 1.

[0034] Furthermore, solenoid valves are installed inside the second distribution pipe 20. By installing solenoid valves inside the second distribution pipe 20, it is convenient for the staff to control the air circulation in different annular aeration pipes 2.
