For example, the broadcasting device 22 notifies local residents of possible flash floods. When the sediment gravity exceeds the preset threshold, the information processor 18 transmits the sediment information to the water pump station management department through the communication device 21 to remind the staff to clean up the silt in time.

The heavy object pressure sensor 31 identifies the amount of silt deposited and transmits the information to the single-chip microcomputer 7. The single-chip microcomputer 7 determines that the amount of silt deposited exceeds the preset threshold and sends a command to the support column 35 through the communication line 6. The support column controls the first lifting rod 36 and the second lifting rod 37 to pull the sewage storage tank 19 above the river, so as to facilitate the staff to clean the sewage storage tank.
