Description

Shut-off device and diverter well with connecting seat

technical field

The utility model relates to the field of municipal engineering, in particular to a shut-off device with a connecting seat.

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 interception pipe, which divert the domestic sewage or initial rainwater and later rainwater in the drainage pipe, 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 then discharged up to 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 diverted rainwater pipe or a sewage pipe or a confluent confluence pipe, the devices for diverting or intercepting flow use a gate or a weir gate to switch the corresponding outlet pipe and sewage interception pipe. The power source is electric or hydraulic. However, in reality, the electric control has the following problems: 1. In the closed pipeline and sewage environment, flammable and explosive biogas is generally generated, and the general electric control device is easy to explode and unsafe. Therefore, when the electric control device is applied All require that the electronic control part in contact with the biogas must have explosion-proof function, so the price of the electronic control system is relatively expensive and the cost is high; 2. In the environment with severe stormy weather, there will be a power outage, and the power will be diverted after the power outage. The equipment in wells, abandoned wells or interception wells cannot work normally, resulting in urban waterlogging and other situations; 3. In rainstorm weather, the flooding of diversion wells, abandoned wells and interception wells is between several hours and several days. In this way, the use of electronic control devices that are completely suitable for underwater use is too redundant and the cost is too high, while the commonly used IP68-rated electronic control devices have a flooding capacity within a few hours, and there is also a situation of insufficient capacity; 4. The device of the electronic control system uses unsafe voltage, and the high voltage is not safe and is prone to accidents; 5. After the electrical equipment is flooded, it is easy to leak electricity, and there is a danger of electric shock; 6. When the electronic control equipment (gate, weir gate) is running It needs to travel up or down, exposing the urban ground, affecting the beautiful urban landscape and traffic, and the excavation area during construction is large; 7. The electric control system uses 380V three-phase electricity, the municipal power grid cannot supply power, and there is difficulty in power supply question.

In particular, it is not easy to solve for the occasions requiring concealed installation, and for the power supply of the electronic control system and the cost incurred. There are also certain problems in hydraulic control: the hydraulic station uses high-pressure oil pipes, and the cost of the hydraulic station and the high-pressure oil pipes is relatively high; the rupture of the high-pressure oil pipes and oil leakage will pollute the environment; after the electrical equipment is flooded, it is easy to leak electricity, and there is a danger of electric shock; electric control equipment ( Gates, weir gates) need to travel up or down during operation, exposing the urban ground, affecting the beautiful traffic of the urban landscape, and the excavation area during construction is large.

The travel space of the gate or weir gate is large, the excavated foundation pit is generally larger, the construction volume is large, and the construction is inconvenient, and the later maintenance, disassembly and installation are more complicated, and the underground environment is harsh and dangerous, and it is not suitable for long-term operation.

To sum up, there is an urgent need for a diverter device that can replace the gate or the weir gate, can be installed and replaced as a whole, is convenient for installation and maintenance, and is safe and reliable.
