[0021] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, during the use of the present device, the present device can first be placed in the corresponding sewage. By utilizing the presence of the water inlet 7, the sewage can automatically flow into the interior of the shell 4 through the water inlet 7, and then accumulate on the top of the sealing plug 5. Since the present device is provided with a floating plate 14 and a blocking block 8, as the sewage accumulates above the sealing plug 5, the buoyancy effect of the water on the floating plate 14 can be utilized to enable the floating plate 14 to move upward with the water level. By utilizing the up and down movement of the floating plate 14, the blocking block 8 can be driven to move upward.
