Description

Shutters and diverter wells

technical field

The utility model relates to the field of municipal engineering, in particular to an intercepting device and a diverting well.

Background technique

At present, in the diversion well, abandonment well and interception well system, the system is composed of water inlet pipe, water outlet pipe and sewage intercepting pipe, which divert the domestic sewage in the drainage pipe or the initial rainwater and later rainwater, among which 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 into the natural water body .

In reality, whether it is a rainwater pipe of a diversion system or a sewage pipe or a confluence pipe of a confluence system, the device for realizing diversion or interception is to use gates or weirs to switch the corresponding outlet pipes and sewage interception pipes. The power source is electric or hydraulic. 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.

Especially, for the occasions requiring concealed installation, it is not easy to solve the power supply and the generated cost of the electric control system. 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, the commonly used gate or weir gate has a large travel space, and the excavated foundation pit is generally enlarged, which is inconvenient for construction due to the large amount of engineering, and the later maintenance, disassembly and installation are more complicated, and the underground environment is harsh and dangerous, so it is not suitable for long-term operation.

In summary, there is an urgent need for a device that can replace gates or weir gates, is easy to install and maintain, and is safe and reliable.
