The monitoring device is one or more of a device for monitoring liquid level, a device for monitoring water quality, a device for monitoring rainfall and a device for monitoring rainfall time, and correspondingly, the water body signal is one or more of a liquid level signal, a water quality signal, a rainfall signal and rainfall time.

Further, there is a predetermined threshold corresponding to the water signal, which may be referred to as a vacuum threshold. If the water body signal is lower than the vacuum threshold value, the controller controls the first on-off device 3 and the air inlet device 5 to be closed, and controls the vacuumizing device 7 to vacuumize the storage room 102, so that the vacuumizing process is executed. If the water body signal is higher than the vacuum threshold value and the storage room 102 is in a vacuum state, the controller controls the first on-off device 3 to be opened, so that the liquid in the diversion room 101 is sucked to the storage room 102 to be stored, and the water storage process is executed.

Further, when the monitoring device is a device for monitoring the liquid level, the water body signal is a signal based on the liquid level height, and the vacuum threshold is a threshold based on the liquid level height. In order to avoid air from entering the storage compartment 102 from the liquid passage opening, the vacuum threshold is higher than the water intake level of the liquid passage opening, so that, when the liquid level in the distribution compartment 101 is lower than the vacuum threshold, the first on-off device 3 is controlled to be closed, enabling air to be prevented from entering the storage compartment 102 from the liquid passage opening.

Further, in the flushing process, as to when to open the air inlet device 5, in an embodiment, after the storage room 102 reaches a preset water level threshold, the air inlet device 5 is opened, the storage room 102 is communicated with the atmosphere, after the storage room 102 is vacuumed, the third shut-off device 4 is opened and the second shut-off device 11 is closed, and then the first shut-off device 3 is instantly and completely opened, so that the liquid stored in the storage room 102 instantly passes through the diversion room 101 and then is discharged from the water outlet, so as to flush the drainage pipes downstream of the storage room 102 and the diversion room 101. Specifically, in the utility model discloses in, 102 broken vacuum back between the regulation, can make the retaining potential energy of 102 convert between the regulation and wash kinetic energy through closing second break-make equipment 11 and instantaneously opening first break-make equipment 3 completely to the utilization is washed kinetic energy and can be realized washing the regulation between 102 bottom and reposition of redundant personnel 101 low reaches drain pipe, takes away silt. It should be noted that, for the instant full opening of the first on-off device 3, the full opening of the first on-off device 3 can be realized within a preset time, and a user can adjust the preset time according to actual needs, for example, the preset time can be set to 3 to 5 seconds.
