The shunt method of the separate system of the utility model, specifically includes,
When the connection of the first water outlet cuts dirty pipe 10, when the second water outlet is connected to rain pipe 101, shunt method is as follows:
When no rainwater enters separate system, flashboard assembly is located at the second position, and flashboard assembly blocks bypass outlet 13, Water inlet, import 11, outlet 12 and the conducting of the first water outlet;When rain enters separate system, initial rainwater passes through first Water outlet, which is discharged into, cuts dirty pipe 10;
During rainwater discharge, signal pickup assembly acquires rainwater information, and acquisition signal is sent to controller 5, initial rainwater is discharged into from the first water outlet cut dirty pipe 10 after, when separate system is rainfall middle and later periods cleaner rainwater, control Device 5 processed controls pneumatic actuation component according to acquisition signal, and flashboard assembly is switched to first position, flashboard assembly from the second position Outlet 12 is blocked, position sensor incudes the movement of flashboard assembly switching position, and whether in place information sends control to by flashboard 22 Whether in place device 5 processed, controller 5 confirm flashboard 22.At this point, water inlet, import 11, bypass outlet 13 and the second water outlet are led Logical, rainwater is discharged into rain pipe 101 by the second water outlet.
After rainfall, latter stage rainwater becomes muddy, and signal pickup assembly acquires the rainwater information in separate system, control Device 5 controls pneumatic actuation component according to acquisition signal, and flashboard assembly is switched to the second position, bypass outlet 13 from first position In off state, outlet 13 is opened, and latter stage rainwater, which is discharged into, cuts dirty pipe 10.
When the first water outlet is connected to rain pipe 101, and the connection of the second water outlet cuts dirty pipe 10, shunt method is as follows:
When no rainwater enters separate system, flashboard assembly is located at first position, and flashboard assembly blocks bypass outlet 13, Water inlet, import 11, outlet 12 and the conducting of the first water outlet;When rain enters separate system, initial rainwater passes through first Water outlet, which is discharged into, cuts dirty pipe 10;
According to the rainwater information for entering separate system, flashboard assembly is switched to the second position, flashboard group from first position Part blocks outlet 12, water inlet, import 11, bypass outlet 13 and the conducting of the second water outlet, and middle and later periods rainwater passes through the second water outlet Mouth is discharged into rain pipe 101.
Specifically, it is connected to the first water outlet and cuts dirty pipe 10, the second water outlet is connected to the shunting principle class of rain pipe 101 Seemingly.In addition, part flow arrangement and separate system are also suitable when the water for flowing into separate system is sanitary sewage.
Shown in Figure 1, in the present embodiment, the connection of the first water outlet cuts dirty pipe 10, and the second water outlet is connected to rain pipe 101。
The present invention provides embodiment one: based on the above technical solution, information collecting device includes rainfall gauge 8, is used In metering amount of rainfall, and amount of rainfall information is sent to controller 5;
When fine day, flashboard 22 is horizontally disposed, in the raw, closes bypass outlet 13.The runner of outlet 12 is opened, pipe Sewage in road is directly discharged to cut dirty pipe 10.Wherein, sewage includes initial rainwater.
When rainfall, the flashboard 22 in initial stage device in the raw, export 12 runner open, water conservancy diversion initial rainwater into Enter to cut dirty pipe 10, while rainfall gauge 8 starts to measure rainfall, when variable, which measures, reaches setting value, the control compression of controller 5 Compressed gas is conveyed to cylinder 21 through gas transmission pipeline 4 by gas source 3, and the elongation driving flashboard 22 of cylinder 21 opens bypass outlet 13, bypass outlet 13 is in the conductive state, i.e. the second water outlet conducting, rainfall middle and later periods cleaner rainwater directly passes through second Water outlet drains into rainwater pipeline 11.
After rainfall, rainfall gauge 8 stops metering, and after reaching setting time, controller 5 controls cylinder 21 and shrinks, and drives Dynamic flashboard 22 closes bypass outlet 13, and flashboard 22 is restored to nature, and bypass outlet 13 is in off state, and outlet 13 is opened It opens, sewage, which is discharged into, cuts dirty pipe 10.
On the basis of example 1, information collecting device can also include water monitor, and water monitor is set to the Two water outlets are sent to controller 5 for monitoring water quality, and by the water quality information monitored;
After rainfall, when monitoring water quality information is preset sewage information, controller controls cylinder 21 and shrinks, and drives Dynamic flashboard 22 closes bypass outlet 13, and bypass outlet 13 be in off state, sewage from water inlet, import 11, export 12 and the The discharge of one water outlet.
On the basis of example 1, information collecting device can also include liquidometer, and liquidometer is set to the second water outlet, The liquid level of rainwater is flowed into for measuring the second water outlet, and liquid level information is sent to controller 5;
After rainfall, when measuring liquid level information lower than default liquid level, controller 5 controls cylinder 21 and shrinks, driving Flashboard 22 closes bypass outlet 13, and bypass outlet 13 be in off state, sewage from water inlet, import 11, export 12 and first Water outlet discharge.It is of course also possible to which liquidometer is arranged simultaneously in the setting liquidometer of import 11 or import 11, bypass outlet 13.
The present invention also provides a kind of embodiment two, the difference with embodiment one is: information collecting device includes water quality prison Device is surveyed, water monitor is set to import 11, is sent to controller 5 for monitoring water quality, and by the water quality information monitored.
When monitoring water quality information is preset rainwater information, controller 5 controls compressed gas source 3 and passes through compressed gas Gas transmission pipeline 4 is conveyed to cylinder 21, and the elongation driving flashboard 22 of cylinder 21 opens bypass outlet 13, and bypass outlet 13 is in and leads Logical state.Wherein, rainfall middle and later periods cleaner rainwater is rainwater information.
When monitoring water quality information is preset sewage information, controller 5 controls cylinder 21 and shrinks, and drives flashboard 22 Bypass outlet 13 is closed, bypass outlet 13 is in off state.Wherein, initial rainwater and sewage are sewage information.
The present invention also provides a kind of embodiment three, the difference with embodiment one is: information collecting device can also include Liquidometer, liquidometer are installed in well body structure, are sent to for detecting the intracorporal liquid level of well, and by the liquid level information monitored Controller 5.The prefabricated H1 and H2 of liquid level, and H2 > H1 are set,
When the level value that liquidometer detects is less than H1 or is greater than H2, part flow arrangement is located at the second position, cuts dirty pipe and leads It is logical, rain pipe cut-off;
When the level value that liquidometer detects between h, and h 2 when, part flow arrangement is located at first position, cut dirty pipe cut-off, Rain pipe conducting.
The present invention can also calculate rain time by timer, control flashboard assembly in first position according to rain time Switch between the second position.It is, of course, also possible to be used cooperatively by least rainfall gauge and timer, at least timer and water quality Monitor, at least timer and liquidometer with the use of etc. modes realize the rainwater information of acquisition separate system.
Those skilled in the art can carry out various modifications to the utility model embodiment and modification, if these are modified With modification within the scope of the claims of the present invention and its equivalent technology, then these modifications and variations are also practical new at this Within the protection scope of type.
The prior art that the content being not described in detail in specification is known to the skilled person.
