In some possible embodiments, the drain outlet 122 is provided with a drain valve 123, which is a solenoid valve, and the time T3 for which the solenoid valve is opened is set according to the time T1 for which the flexible stop is opened, and/or the time T4 for which the solenoid valve is closed is set according to the time T2 for which the flexible stop is closed.
In order to better realize the "real-time" control of the opening and/or closing time of the flexible shutoff device 1, the technical effect of "precise" control of the opening and/or closing is achieved, 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.

This is because if the bent height of the inverted U-shaped bend is lower than the height of the rainwater riser pipe in the buffer box 34 after penetrating into the first water outlet 33, then as the rainwater in the rainwater riser pipe 2 continuously flows into the seal cavity 12 through the conduction pipe 41 until the seal cavity 12 is filled, the rainwater in the seal cavity 12 flows into the pressure accumulation cavity 11 through the air pipe 3 at this time, and once the rainwater enters the pressure accumulation cavity 11, the rainwater cannot be discharged; therefore, in order to avoid rainwater in the seal cavity 12 flowing into the accumulator cavity 11, in this embodiment, the bent height of the inverted U-shaped bend is designed to be equal to or greater than the height of the rainwater riser pipe in the buffer box 34 after penetrating into the first water outlet 33, so that even when the seal cavity 12 is filled with the flowing rainwater, at this time, since the bent height is higher than the height of the rainwater riser pipe in the buffer box 34 after penetrating into the first water outlet 33, the rainwater can be preferentially discharged from the first water outlet 32 through the rainwater riser pipe 2, and then the technical effect of effectively avoiding that the rainwater in the seal cavity 12 flows into the accumulator cavity 11 and cannot be discharged is achieved.
In some possible embodiments, the drain outlet 122 is provided with a drain valve 123, and the drain valve 123 is a manual valve having an opening degree set according to a time T1 when the flexible stop is required to be opened and/or a time T2 when the flexible stop is required to be closed.
Since the second embodiment and the first embodiment are two different embodiments belonging to the same inventive concept, the same structural parts as those of the first embodiment are not described in detail in the second embodiment, and other parts not described in detail in the second embodiment can be referred to the first embodiment.
