[0025] Need to be explained: when dredging aeration hole 8 regularly, staff can realize that compressed air fills in air bag 605 and discharges air bag 605 by controlling the opening and closing of second control valve 608 and first control valve 607, and compressed air will enter air bag 605 through inflating pipe 600, and air bag 605 expansion will extrude extrusion plate 602, and extrusion plate 602 can extrude spring 604 and dredging needle 603, and dredging needle 603 can be inserted into aeration pipe 8, so as to dredge aeration pipe 8.

[0026] The stirring mechanism 7 comprises two groups of fixed blocks 700 arranged on the outer wall of the aeration pipe 5. The outer wall of the aeration pipe 5 is provided with a driving shaft 701, the two ends of the driving shaft 701 are respectively connected with bearings arranged on the opposite side walls of the two groups of fixed blocks 700, and the outer wall of the driving shaft 701 is provided with a plurality of stirring impellers 702 arranged correspondingly to the aeration holes 8.

[0027] It should be noted that when the aeration is performed, the overflow of the bubbles will push the water flow, and the water flow will rotate the stirring impeller 702, so that the stirring impeller 702 can stir the water and accelerate the diffusion of the bubbles, thereby further improving the oxygenation effect.

[0028] The plurality of dredging needles 603 are linearly arranged on the side wall of the extrusion plate 602, the dredging needles 603 are made of stainless steel material, the aeration holes 8 are linearly arranged on the outer wall of the aeration pipe 5, and the dredging needles 603 correspond to the aeration holes 8 to better dredge the aeration holes 8.

When the bubbles are discharged, the bubbles will push the water flow, and the water flow will rotate the stirring impeller 702, so that the stirring impeller 702 can stir the water and accelerate the diffusion of the bubbles, thereby further improving the oxygenation effect.

[0030] When the aeration pipe 5 is located in the water, impurities in the water will be adsorbed on the outer wall of the aeration pipe 5 to block the aeration holes 8. When the aeration holes 8 need to be dredged, the second control valve 608 is opened and the first control valve 607 is closed, so that the compressed air enters the air bag 605 through the inflation pipe 600. The inflation of the air bag 605 will extrude the extrusion plate 602, and the extrusion plate 602 can extrude the spring 604 and the dredging needle 603. The dredging needle 603 can be inserted into the aeration pipe 8 to dredge the aeration pipe 8, so as to avoid the blockage of the aeration holes 8 and affect the generation of bubbles. After the dredging is completed, the second control valve 608 is closed and the first control valve 607 is opened. The compressed air in the air bag 605 will be discharged from the air outlet pipe 606 through the inflation pipe 600, and the air bag 605 will be contracted. At this time, under the action of the elasticity of the spring 604, the dredging needle 603 will be reset, and the dredging needle 603 will be separated from the aeration holes 8.

[0031] It should be noted that the specific model and specification of the air bag and the air compressor need to be selected and determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, so it is not described in detail.
