[0057] like Figure 3 and Figure 5 As shown, threaded rods 88 are symmetrically welded to the outside of the connecting pipe 85, and the threaded rods 88 pass through the air outlet hood 87 and are threadedly connected to a nut 89 at the bottom end of the air outlet hood 87 for limiting the position of the air outlet hood 87 to prevent the position of the air outlet hood 87 from being offset, thereby making the position of the air outlet hood 87 more precise after installation.

[0059] like Figure 6 and Figure 7 As shown, the installation assembly 6 includes a guide cover 61 slidably connected to the bottom end of the aeration pipe 2, an outer cover 62 is integrally formed on the outer side of the guide cover 61 at the outer side of the aeration pipe 2, a threaded ring 63 is threadedly connected to the outer side of the outer cover 62, an extrusion rod 65 is fittedly connected to the top of the inner wall of the threaded ring 63, and an arc strip 68 is fixedly installed on one end of the extrusion rod 65, which can facilitate the installation between the aeration pipe 2 and the circular pipe 7, and increase the sealing of the aeration pipe 2 and the circular pipe 7 after installation, and prevent leakage between the aeration pipe 2 and the circular pipe 7.

[0060] like Figure 6 and Figure 7 As shown, a guide groove 66 is provided inside the outer cover 62 at a position corresponding to one end of the extrusion rod 65, a limit rod 67 is welded inside the outer cover 62 at the position of the guide groove 66, and the extrusion rod 65 is slidably connected to the outside of the limit rod 67, and a grip rod 64 is integrally formed equidistantly on the outside of the threaded ring 63 to facilitate rotation of the threaded ring 63, thereby changing the rotation difficulty of the threaded ring 63, an inclined groove is provided on the top of the inner wall of the threaded ring 63, and a chamfer is provided at the bottom of one end of the limit rod 67 to facilitate driving the displacement of the limit rod 67, thereby changing the displacement difficulty of the limit rod 67.

[0061] Working principle: During the actual use of the device, the user puts the aeration pipe 2 into the outside of the guide cover 61 and the outer cover 62, and then drives the threaded ring 63 to rotate through the grip 64. When the threaded ring 63 rotates, it drives the extrusion rod 65 to move along the inside of the guide groove 66. When the extrusion rod 65 moves, it drives the arc strip 68 to squeeze the outside of the aeration pipe 2, so that the aeration pipe 2 and the outside of the guide cover 61 are squeezed and fixed, which can facilitate the installation and fixation of the aeration pipe 2, change the installation and fixation difficulty between the aeration pipe 2 and the circular pipe 7, and at the same time increase the sealing between the aeration pipe 2 and the installation assembly 6, prevent the phenomenon of liquid entering the inside of the pipe, so as to facilitate the aeration of the inside of the breeding box 1;

[0062] Then the personnel pulls the air hood 87, and the air hood 87 moves along the threaded rod 88 and fits with one end surface of the nut 89. Then the personnel swings the air hood 87, and the air hood 87 drives the connecting pipe 85 to swing. When the connecting pipe 85 swings, the hose 84 is driven to bend. Then the swinging connecting pipe 85 is fixed by the bolt structure. Then the personnel rotates the internal thread ring 83. When the internal thread ring 83 rotates, the connecting pipe 85 is driven to rotate through the rotating bar 86, so that the position of the air hood 87 is changed. Then the personnel rotates the adjustment cover 813. When the adjustment cover 813 rotates, the direction of aeration is changed, so that the aeration position inside the culture box 1 can be adjusted, so that the aeration position can be at different depths and different positions inside the culture box 1, so that the aeration inside the culture box 1 is uniform, and the phenomenon of large-scale shrimp seedlings gathering is prevented, thereby preventing the shrimp seedlings from hypoxia and collision death caused by the gathering, thereby improving the survival rate of the shrimp seedlings.

[0063] Finally, the personnel rotates the screw rod 812, and when the screw rod 812 rotates, it drives the blocking block 82 close to the air outlet of the air outlet hood 87. At this time, the size of the air outlet of the air outlet hood 87 is adjusted, thereby adjusting the aeration size to prevent the aeration from being too large or too small. At this time, the screen 811 is used to prevent the shrimp seedlings from entering the aeration structure 8, thereby protecting the shrimp seedlings and preventing the shrimp seedlings from dying inside the aeration structure 8 and causing blockage inside the aeration structure 8.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
