At present, in the diversion well, abandonment well and interception well system, the system is composed of water inlet pipe, outlet pipe and sewage intercepting pipe, which divert the domestic sewage or dirty rainwater and later rainwater in the drainage pipe, among which domestic sewage Or the dirty rainwater is intercepted to the sewage pipe and then transported to the sewage treatment plant for treatment and discharged after reaching the standard (further, the dirty rainwater can be stored or intercepted to the sewage treatment plant for treatment and discharged after reaching the standard), and the clean rainwater is directly discharged to the natural environment. in a body of water.

The devices for diverting or intercepting flow all use gates or weir gates to switch the corresponding outlet pipes and sewage intercepting pipes, and the power source of the gate valves is electricity or hydraulic pressure. However, in reality, electric control has the following problems: 1. Generally, flammable and explosive biogas will be produced in closed pipelines and sewage environments. General electric control devices are prone to explosion and unsafe. Therefore, when using electric control devices It is required that the electronic control part in contact with the biogas must have an explosion-proof function, so the price of the electronic control system is relatively expensive and the cost is high; 2. In the severe environment of stormy weather, power failure will occur, and the power will be diverted after power failure The equipment in the diversion well, abandonment well or interception well cannot work normally, resulting in urban waterlogging and other situations; 3. In rainy weather, the flooding of diversion wells, abandonment wells and interception wells ranges from several hours to several days In this way, the use of an electronic control device that is completely suitable for underwater use will be too redundant and cost too high, and the commonly used IP68-level electronic control device can be submerged within a few hours, and there are also situations where the capacity is insufficient; 4. The devices of the electric control system use unsafe voltage, and the high voltage is unsafe and prone to accidents; 5. After the electrical equipment is flooded, it is easy to leak electricity and there is a risk of electric shock; 6. When the electric control equipment (gates, weirs) are running It needs an upward or downward journey, which exposes the urban ground, which affects the urban landscape and traffic, and the excavation area is large during construction; 7. The electric control system uses 380V three-phase electricity, and the municipal power grid cannot supply power, so there is a problem of power supply difficulty question.

In addition to the above-mentioned problems in the existing interception wells, diversion wells or abandonment wells, when urban waterlogging occurs, the channel to enter the natural water body or rainwater pipes will be quickly opened. At this time, there will be more dirty rainwater in the well. It will quickly pour into natural water bodies and cause serious environmental pollution.
