Description
Technical Field
The invention relates to municipal rainwater and sewage diversion, in particular to a pipeline diversion system with an inlet overflow pipe and an outlet overflow pipe, and belongs to the technical field of civil buildings and municipal water supply and drainage.
Background
At present, in a diversion well, a abandoning well and an intercepting well system, the system is composed of a water inlet pipe, a water outlet pipe and a sewage intercepting pipe, domestic sewage or initial rainwater and later stage rainwater in a drain pipe are diverted, wherein the domestic sewage or the initial rainwater is intercepted to a sewage pipe and then is conveyed to a sewage treatment plant for treatment and then is discharged after reaching the standard (further, the initial rainwater can be stored or intercepted to the sewage treatment plant for treatment and then is discharged after reaching the standard), and the middle and later stage rainwater is directly discharged to a natural water body.
In reality, devices for realizing the cut-off and conduction functions in a diversion well, a abandoning well and an intercepting well generally adopt electric control or hydraulic control. However, in reality, electric control or hydraulic control is not suitable:
flammable and explosive biogas is generally generated in a closed pipeline and a sewage environment, so that an electric control part in contact with the biogas is required to have an explosion-proof function when an electric control type device is applied, the price of an electric control type system is expensive, and the flooding conditions in a diversion well, a flow abandoning well and an intercepting well are between hours and days, so that the redundancy and the cost of the electric control device which is completely suitable for underwater use are overlarge, and the flooding capacity of a common IP 68-grade electric control device is insufficient within hours. In addition, the device adopting the electric control system generally installs the electric control part on the ground, and the electric control device is not suitable for occasions requiring concealed installation.
To solve the above problems, a hydraulic control type apparatus has been developed. The hydraulic control device has no explosion hidden trouble and can be flooded for a long time. But it also has obvious shortcomings, the hydraulic control system has higher working pressure, has very high requirements on the pressure resistance and the leakage resistance of the hydraulic pipeline, and must use two oil pipes: the high-pressure oil pipe is expensive, so the price of the whole system is expensive under the requirements of unit price and longer pipeline. Further, since the operation is performed at a high pressure, safety accidents are easily caused once leakage problems occur. And the leaked hydraulic oil is easy to pollute the environment in the debugging and overhauling processes.

When rainfall enters the diversion system in a rainy day, because the initial rainfall does not reach the threshold value, the corresponding controller still controls the control valve to enable the water outlet to be in a conduction state according to the rainfall which does not reach the threshold value, and the entering initial rainwater can enter an initial rainwater pipe or a sewage pipe through the intercepting channel.
And secondly, along with the increase of the rainfall, when the rainfall reaches a threshold value, the controller controls the control valve to act.
And thirdly, changing the cut-off channel controlled by the pneumatic control assembly from a conducting state to a cut-off state after the control valve acts.
And fourthly, after the intercepting channel is changed into a cut-off state, rainwater in the middle and later periods is accumulated in the drain pipe until the rainwater overflows from the overflow pipe, and accordingly the fluid at the inlet is correspondingly distributed to the rainwater pipe.
State one is entered when the amount of rain decreases below the threshold.

Further, since the pipe branching device 40 further includes a position sensor, by providing the position sensor on the inner peripheral wall of the outlet of the pipe branching device 40 where the air bag or the pneumatic pipe clamp valve is provided, and by correspondingly providing the position sensor on the inner wall of the outlet communicated with the sewage pipe, the expanded position of the air bag or the pneumatic pipe clamp valve can be detected in real time one-to-one and the detection signal can be transmitted to the controller to be detected, so that even if a certain air bag or pneumatic pipe clamp valve is blocked or damaged, the problem of which air bag or pneumatic pipe clamp valve is detected can be detected rapidly and specifically:
after the air source pressure is normal and a certain air bag or pneumatic tube pinch valve is not expanded according to requirements, the fault can be quickly checked;
after the fault that the air source detects air leakage all the time and the air source is inflated all the time but can not reach normal pressure occurs, the air bag or pneumatic tube pinch valve or pipeline air leakage can be judged, and the air bag or pneumatic tube pinch valve is judged to have a problem according to the condition of the position sensor.
The present invention is not limited to the above-described embodiments, and it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements are also considered to be within the scope of the present invention. Those not described in detail in this specification are within the skill of the art.
