At present, in a diversion well, a drainage well and a intercepting well system, the system is composed of a water inlet pipe, a water outlet pipe and a sewage pipe, domestic sewage or initial rainwater in the water outlet pipe is diverted, the domestic sewage or the initial rainwater is intercepted to the sewage pipe and then is conveyed to a sewage treatment plant for treatment and then is discharged after reaching standards (further, the initial rainwater can be stored or intercepted to the sewage treatment plant for treatment and then is discharged after reaching standards), and the intermediate and later rainwater is directly discharged to a natural water body.
In reality, devices for realizing cut-off and on functions in a diversion well, a drainage well and a intercepting well generally adopt electric control or hydraulic control. However, in reality, the following problems exist in the electric control: 1. flammable and explosive biogas is generally generated in a closed pipeline and a sewage environment, and a common electric control device is easy to explode and unsafe, so that an electric control part in contact with the biogas is required to have an explosion-proof function when the electric control device is applied, and the price of an electric control system is relatively high and the cost is high; 2. under the severe storm weather, the situation of power failure can occur, and equipment in a diversion well, a abandoned flow well or a intercepting well cannot work normally after power failure, so that urban waterlogging and the like are caused; 3. under the stormwater weather, the flooding conditions of the diversion well, the abandoned flow well and the intercepting well are between a plurality of hours and a plurality of days, so that the redundancy and the cost are too high by adopting the electric control device which is completely suitable for being used underwater, and the flooding capability of the common IP 68-level electric control device is within a plurality of hours, so that the flooding capability is insufficient; 4. the device of the electric control system uses unsafe voltage, and accidents easily occur due to unsafe high-voltage electricity; 5. after the electrical equipment is flooded, electric leakage is easy, and electric shock danger exists; 6. the electronic control equipment (gate and weir gate) needs upward or downward travel when running, exposes urban ground, influences beautiful traffic of urban landscapes, and has large excavation area during construction; 7. the electric control system uses 380V three-phase power, a municipal power grid cannot supply power, and the problem that a power supply is difficult exists.
In particular, for applications requiring concealed installation, and for the power supply and resulting costs of the electrical control system, this is not easily resolved.
