During use, at first the whole device is put into the bottom of the river channel, and the blower 9 is turned on, so that the aeration pipe 8 starts aeration work. When aeration causes severe disturbance of the bottom mud, causing turbidity to rise, and when the turbidity measured by the turbidity sensor reaches above 100 mg/L, the air valve 12 is triggered to connect the inflatable aeration pipe 8 and the lifting air bag 13, and the lifting air bag 13 Inflated, the lifting device 2 begins to rise under the effect of the buoyancy of the lifting air bag 13 .

During the rising process of the lifting device, it is not affected by the one-way limit clip 15 and can rise freely, but cannot fall freely to prevent the suspension of the sediment.

Thereby the lifting device 2 can freely fall to the bottom. When the lifting device 2 falls to the bottom, the clip opening mechanism 18 is triggered, and the clip opening mechanism 18 drives the opening rod 25 to move downward as a whole, thereby driving the stop bolt 21 to move downward and break away from the clamping groove 27, so that the positioning clamp rod 23 moves downward in the first position. Under the action of a spring, it moves away from the lifting rod 1 , so that the one-way limit clip 15 can restore the one-way limit effect on the lifting device 2 .

When needed, the height of the aeration tube 8 can also be adjusted by manually pulling the floating ball 5 to pull the lifting device 2 through the floating ball rope 3 .
