Preferably, rain leader downspout bottom connects 90 degree of elbows, and the water outlet of 90 degree of elbows connects Self-controlled electromagnetic valve, from It need to be located at cistern through another 90 degree of elbows connection rain leader downspout delivery ports, the rain leader downspout delivery port after control electromagnetic valve 8cmm ~ 15cm above bottom surface, flood stream to be formed in working condition.
Liquid level gauge 3 is arranged at cistern water outlet, and use is simple in construction, the convenient floating ball type liquid-level meter of debugging.
Thus, the application method of a kind of roof rain water runoff measuring device of the invention, it is characterised in that
Cistern is set below rain leader downspout delivery port, and rain leader downspout bottom connects 90 degree of elbows, the delivery port of 90 degree of elbows A, Place's connection Self-controlled electromagnetic valve, automatic control solenoid valve is behind the door through another 90 degree of elbow connection rain leader downspout delivery ports, cistern bottom Portion sets pressure sensor;Siphon pipe is set in cistern, liquid level gauge is also set up in cistern, cistern exit sets lock Valve;
B, when rainfall measures, measured by cistern, specifically include step
A, cistern gate valve is closed;
B, pressure when pressure sensor measurement cistern pressure is empty water, controller control Self controlling valve are opened;
C, rain water on roof is collected through rain leader downspout and flowed into cistern, and is held in accumulation in cistern until reaching pond;
D, now pressure sensor measurement cistern pressure position full water when pressure, controller control Self controlling valve closure, stop into Water, and once counted;Meanwhile water surface elevation reaches highest in siphon pipe, water side starts water outlet, and siphonic effect is touched Hair, until water storage pool inner water almost all is discharged after siphon, cistern is emptied;After emptying, pressure sensor is able to again The signal of Self controlling valve is opened in secondary output, and repeat step c and d is until stop rainfall;
C, calculate rain leader downspout and collect gross rainfall V1:
When cistern last time is intake, the water surface possibly can not reach siphon pipe peak, i.e. siphon can not trigger, then by people The mode of part work and part study number, water level real on liquid level gauge is read, cistern is then emptied by blow-down pipe.So eventually through water storage The rain leader downspout that pond measures collects gross rainfall:
V1:Rain leader downspout collects gross rainfall;
v:The maximum amount of water that cistern can carry(Chi Rong);
n:The number of siphon triggering, i.e., the number that controller meter obtains;
v’:Water in the counted cistern of reading of last liquid level gauge;

By the way that the run-off of rainfall twice can quantify roof greening transformation to rainfall runoff before measurement transformation and after transformation The actual effect of reduction.
Example is changed to the roof of Shanghai City downtown unit, it transforms roof area 50m2, monitored each 1 before and after transformation Field rainfall, rainfall is respectively 12.89mm and 19.01mm, and rainfall duration is respectively 42min and 55min, and it is 3min to prolong peak time And 7min, runoff coefficient are respectively 0.814 and 0.395.
Specific practice is:
1st, rainfall Monitoring Data is surveyed every 1min, the rainfall Monitoring Data can be measured by rainfall gauge;
2nd, a rainwater flow monitoring data are arranged every 1min.In order to ensure the result of rainwater flow monitoring and rainfall monitoring phase It is corresponding, so the monitoring frequency of rainwater flow should once either 1min twice or four times, can so be sorted out in 1min The data at 1min intervals.
3rd, generating process figure, the transformation forward and backward peak delay time is compared.For example before transformation, rainfall peak value appears in 16:43 Point, peak flow appears in 16:46, so transformation leading peak is 3min;And after transforming, rainfall peak value appears in 13:33 points, stream Amount peak value appears in 13:40 points, so transformation leading peak is 7min;So effect of the final roof greening transformation to Yan Feng is 7min-3min, it is 4min.
4th, rainfall total value and rainwater flow total value are calculated, carries out ratio calculation, calculates runoff coefficient situation of change.Such as Rainfall is 12.89mm before transformation, and rainfall volume is 644.28L, and it is 524.31L to detect stream, then play rainfall runoff coefficient For 0.814;Rainfall is 19.01mm before such as transforming, and rainfall volume is 950.65L, and it is 375.62L to detect stream, then play drops Rain runoff coefficient is 0.395.
By the rainwater flow of the system monitoring rain water on roof downpipe, with reference to the rainfall monitoring of online rainfall monitoring instrument Data, it can be used for after assessing a rainfall, the ratio of overall rainwater flow and rainfall(Runoff coefficient), it can be seen that room The situation of change of the front and rear runoff coefficient of face spongeization transformation.
The technical scope of the present invention does not limit to.Embodiments above is only explanation of the invention, art technology Personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but as long as All protected in scope of the presently claimed invention by Patent Law.
