The invention relates to a diversion well with a cut-off device installed on the inner side, which comprises a diversion well body, wherein the diversion well body is provided with a water inlet and two water outlets, the water inlet is used for communicating an upstream drainage pipeline, the first water outlet is used for communicating a downstream drainage pipeline or a natural water body, thesecond water outlet is used for communicating a sewage pipe or a primary rain pipe or a sewage treatment facility or a primary rainwater treatment facility or a regulating storage tank; a shut-off device is provided with a connecting seat assembly, an elastic sleeve and a sealing shell which forms a seal around the elastic sleeve, an air cavity or a water cavity is formed between the sealing shelland the outer wall of the elastic sleeve, the air cavity or the water cavity is provided with an inlet, the elastic sleeve is provided with a flow passage, one end of the sealing shell is provided with a connecting seat component; a second cut-off device is arranged at the second outlet, the second cut-off device is positioned in the diversion well, the connecting seat component of the second cut-off device is connected with the inner wall of the diversion well body, and the flow passage is docked with the second outlet.

Description

technical field [0001] The invention relates to the diversion of municipal rainwater and sewage, in particular to a diversion well with an intercepting device installed inside and a control system, belonging to the technical fields of civil buildings and municipal water supply and drainage. Background technique [0002] At present, in the diversion well, abandonment well and interception well system, the system is composed of water inlet pipe, outlet pipe and sewage pipe, and the domestic sewage in the drainage pipe or the initial rainwater and the later rainwater are diverted. Among them, the domestic sewage or The initial 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 initial rainwater can be stored or intercepted to the sewage treatment plant for treatment and discharged after reaching the standard), and the middle and late rainwater is directly discharged...

AI Technical Summary

Problems solved by technology

However, in reality, electric control has the following problems: 1. Generally, flammable and explosive methane will be generated in closed pipelines and sewage environments, and general electric control devices are prone to explosion and unsafe, so when applying 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

[0004] In particular, for the occasions requiring concealed installation, and the power supply and costs of the electronic control system are not easy to solve

There are also certain problems in hydraulic control: the hydraulic station uses high-pressure oil pipes, and the cost of the hydraulic station and high-pressure oil pipes is relatively high; the rupture of high-pressure oil pipes will pollute the environment; after the electrical equipment is flooded, it is easy to leak electricity and there is a risk of electric shock; Gates, weir gates) require upward or downward strokes during operation, exposing the urban ground, affecting the urban landscape and traffic, and the excavation area is large during construction

In addition, when remediating living areas, road areas, and outfalls in the existing technology, only the sewage and rainwater conditions in the current location and area are considered, and resources are not shared, and the cost of treatment is relatively high.
