when the flexible cut-off device is opened, rainwater in the pressure accumulation cavity is discharged through the water outlet at the flow speed of V3, and the flexible sleeve starts to expand and recover under the action of self elasticity so that the flexible cut-off device is gradually opened.
Specifically, the method comprises the steps of obtaining the pressure of a pressure accumulation cavity; selecting the installation height of the diverter on the rainwater vertical pipe according to the pressure intensity; a flow dividing piece is arranged according to the installation height, and the water outlet end of the rainwater vertical pipe is communicated with the pressure accumulation cavity through a pipeline; when the flexible cut-off device is closed, rainwater flowing into the rainwater vertical pipe through the water inlet end of the rainwater vertical pipe flows into the pressure accumulation cavity through the water inlet, the first water outlet, the water outlet end of the rainwater vertical pipe and the communicating pipe in turn at the flow speed of V1, and is discharged through the water outlet at the flow speed of V2, and as V1 is larger than V2, the rainwater capacity in the pressure accumulation cavity is continuously increased, and meanwhile, under the action of the water column pressure formed by the rainwater in the rainwater vertical pipe, the flexible cut-off device starts to be compressed and deformed, and then the flexible cut-off device is gradually closed; when the flexible cut-off device is opened, rainwater in the pressure accumulation cavity is discharged through the water outlet at the flow speed of V3, so that the rainwater capacity in the pressure accumulation cavity is gradually reduced, the water column pressure formed by the rainwater in the rainwater vertical pipe is also gradually reduced, the flexible cut-off device starts to expand and recover under the action of self elasticity, and then the flexible cut-off device is gradually opened, so that the opening or closing of the flexible cut-off device is controlled through the water column pressure formed by the rainwater in the rainwater vertical pipe outside a building, a power source is not required to be additionally provided, and the opening and closing of the flexible cut-off device are controlled by utilizing the existing resources to a greater degree, so that the technical effect of reducing the control cost is achieved.
In some possible embodiments, the selecting the setting height of the diverter on the rain water riser according to the pressure includes: and taking the installation height of the rainwater vertical pipe as the highest water level point, so that the water column pressure in the rainwater vertical pipe can gradually extrude the flexible sleeve until the flexible cut-off device is closed as a standard, and selecting the installation height of the flow dividing piece on the rainwater vertical pipe.

In some possible embodiments, the rainwater is discharged through the second water outlet in the diverter when the level of water in the rainwater riser reaches the mounting height. It can be understood by those skilled in the art that, as the amount of rainwater entering the rainwater stand pipe increases, rainwater in the rainwater stand pipe is split to the pressure accumulation cavity through the first water outlet in the split member on one hand, and on the other hand, when the rainwater in the pressure accumulation cavity reaches the pressure accumulation volume, the water level in the rainwater stand pipe can gradually rise at this time, and the rainwater can be discharged from the second water outlet when reaching the set height of the second water outlet in the split member, so that the technical effect of normally discharging the rainwater in the rainwater stand pipe is not influenced.

In order to better realize the "real-time" control of the opening and/or closing time of the flexible cutoff device 1, and achieve the "accurate" control of the opening and/or closing technical effect, the electromagnetic valve can be controlled in real time by setting the electromagnetic valve and adding a controller, for example, the opening time T3 is preset, when the opening time T3 is reached, the controller sends a control command to control the action of the electromagnetic valve, and the closing time T4 is set, and when the closing time T4 is reached, the controller sends a control command to control the action of the electromagnetic valve. Thus realizing the technical effects of real-time and accurate control. In addition, because the electromagnetic valve has low power consumption, the power can be supplied by adopting a storage battery or solar energy mode, and the micro-power and low-power control effect is effectively realized.

when the flexible cut-off device is closed, rainwater flowing into the rainwater vertical pipe through the water inlet end of the rainwater vertical pipe flows into the pressure accumulation cavity at a V1 flow rate through the first water outlet of the flow dividing piece and the water outlet end of the rainwater vertical pipe in sequence, and is discharged through the water outlet at a V2 flow rate, wherein V1 is larger than V2, and the flexible rubber sleeve starts to compress and deform under the action of water pressure so that the flexible cut-off device is gradually closed;
when the flexible cut-off device is opened, rainwater in the pressure accumulation cavity is discharged through the water outlet at the flow speed of V3, and the flexible rubber sleeve begins to expand and recover under the action of self elasticity so that the flexible cut-off device is gradually opened.
