In addition, the base can be arranged at different heights, or the distances among the upper limiting block, the lower limiting block, the floating rod and the closed gas container can be adjusted, so that the whole device is suitable for underground return air tunnels with different sizes and different water depths.
Further, a fixing frame is arranged on one side of the base, and the ball valve is fixed on the fixing frame; the air inlet of the ball valve is communicated with the air pressing pipeline, and when the ball valve is opened, compressed air in the air pressing pipeline can enter the air supply pipeline.
