Further, described rainfall collector is arranged on the top of building, and the outer wall that described device for cleaning pipeline piping clip is fixed on described building extends straight down.
Further, the described mouthful top side-walls that is arranged on described building of collecting.
Further, described liquid-level switch is arranged at the upper position, stage casing of described reservoir.
The present invention also provides a kind of control method of rain collector, when described pressure sensor detection rainfall reaches predetermined value, sends a signal to described Split-flow Control device, and described Split-flow Control device is controlled described motor operated valve and opened, and starts to collect rainwater; When described reservoir water level rises the described liquid-level switch of triggering, described liquid-level switch sends a signal to described Split-flow Control device, and described Split-flow Control device controls motor operated valve and cuts out, and stops collecting rainwater.
Further, in described Split-flow Control device is controlled first scheduled time after described motor operated valve is opened, if receive rainfall for the second time, and described liquid-level switch is not when trigger, and described Split-flow Control device is directly controlled described motor operated valve and opened, continuation collection rainwater.
Further, at described Split-flow Control device, control after second scheduled time after described motor operated valve is opened, described Split-flow Control device controls described motor operated valve and cuts out, described Split-flow Control device of while is controlled described electromagnetic valve and is opened, after described ducted water is discharged, described Split-flow Control device is controlled described closed electromagnetic valve, and described second scheduled time was more than or equal to for first scheduled time.
Rain collector provided by the invention and control method, by the opportunity of Split-flow Control device judgement collection rainwater, got rid of the poor rainwater of water quality at rainfall initial stage effectively, improved the water quality of collecting rainwater.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms the application's a part, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 schematically illustrates the rain collector that the invention process example provides.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to Fig. 1, show the rain collector that the present embodiment provides, comprise rainfall collector 2 and collect mouth 7, rainfall collector 2 is arranged on the top of building 1, rainfall collector 2 is communicated with pipeline 3, and the outer wall that pipeline 3 is fixed on building 1 by pipeline clamp 31 extends straight down, is provided with pressure sensor 11 and electromagnetic valve 12 in the stage casing of pipeline 3, pressure sensor 11 is at least 5 meters with the vertical drop of rainfall collector 2, and electromagnetic valve 12 is in normally off.Pressure sensor 11 and electromagnetic valve 12 all communicate to connect with Split-flow Control device 7, and pressure sensor 11, by pre-set program, may be measured the amount of precipitation of rainwater.Collect mouthfuls 7 and be arranged at eminence, for example in the present embodiment in the top of building 1 side-walls.Collect mouth 7 by rain leader downspout 4, be communicated to rainwater inspection well 5 downwards, rainwater inspection well 5 middle parts are provided with bleed off pipe 6, rainwater inspection well 5 is further communicated to reservoir 9 by motor operated valve 13, motor operated valve 13 is arranged in electrically operated valve well 8, upper position, stage casing at reservoir 9, is provided with liquid-level switch 14, and motor operated valve 13 all communicates to connect with Split-flow Control device 7 with liquid-level switch 14.
After rainfall starts, rainfall collector 2 starts to collect rainwater, by funnel flow ipe 3, the interior water level of pipeline 3 rises, with the pressure sensor 11 being installed on pipeline 3, detect amount of precipitation, more multiple pressure power is larger in rainfall, and when the initial stage, amount of precipitation reached 4mm, pressure sensor 11 sends collects rainwater signal to Split-flow Control device 7.By Split-flow Control device 7 transmitted signals, motor operated valve 13 is opened, and starts to collect rainwater.Before receiving signal, motor operated valve 13 is all the time in closed condition, and early-stage rainwater is by bleed off pipe 6 discharges of rainwater inspection well 5.
When reservoir 9 is full, liquid-level switch 14 sends a signal to Split-flow Control device 7, controls motor operated valve 13 and closes, and does not regather rainwater.
Abandoned stream periodic Control: the abandoned stream cycle, for since 72 hours of rainfall, if abandoned stream process is not carried out in rainfall again in 72 hours, that is to say in 72 hours, and in the situation that reservoir water 9 is discontented, motor operated valve 13 is all the time in opening.
Abandoned stream end cycle is controlled: timing when rainfall rainfall starts to collect rainwater, when the time is accumulated to 72 hours, by Split-flow Control device 7, control, motor operated valve 13 cuts out, electromagnetic valve 12 is opened, the rainwater in discharge tube 3, and after 10 minutes, the interior storm-water drainage of pipeline 3 is complete, electromagnetic valve 12 cuts out, and whole system returns to original state.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
