By setting up a float 10 and a counterweight frame 7, the air outlet pipe 4 can be suspended in the water, and the pull rope 8 can be wound by rotating the winding roller 9, so that the distance between the air outlet pipe 4 and the air jet branch pipe 5 and the bottom of the breeding pool or pond can be adjusted to ensure that the air outlet pipe 4 does not contact the bottom of the breeding pool or pond, effectively avoiding the air dispersion mechanism 6 from blowing up the dirt settled at the bottom, causing water pollution.

[0026] The length of the pull rope 8 can be adjusted by rotating the winding roller 9, thereby adjusting the distance between the air outlet pipe 4 and the air jet branch pipe 5 and the bottom of the breeding pond or pond, so that the equipment can be used in rings with different water depths, further improving the applicability of the equipment.

[0027] The outer surface of the support frame 2 is fixedly connected to a waterproof motor 11, and the rotating end of the waterproof motor 11 is fixedly connected to the end of the winding roller 9.
