Technical field
The present invention relates to a kind of rainwater collection utilization unit, be specifically related to the initial rain water drainage tank of top, a kind of pond rainfall automatic control.
Background technology
Along with being on the rise of environmental disruption, city and area that water resource lacks, it is particularly important that rainwater catchment system becomes.Due to the rainfall initial stage, rainwater can be subject to pollution in various degree in the time of the roofing of flowing through, ground or irrigation canals and ditches, the Rainwater Initial of collecting contains a lot of impurity, water quality is comparatively muddy, but along with continuing of rainfall, middle and later periods water quality is significantly improved, the collection of general rainwater is all to adopt initial Split-flow mode, by the early-stage rainwater run-off abandoned stream of 2 ~ 5mm, collect cleaner rainwater of middle and later periods.
Common initial rain water drainage tank mainly contains the several types such as volume or half volume type, flow or rainfall regime at present.
Volume or half volume type initial Split-flow pond: early-stage rainwater is introduced in drainage tank and stores (all or part of early-stage rainwater amount), reaches after the volume setting, start to collect cleaner rainwater; Every rainfall also needs machinery later or manually opens valve by emptying the early-stage rainwater storing, for abandoned stream early-stage rainwater is next time prepared.This volume or half volume type initial Split-flow pond are taken up an area larger, consume the energy, need manual operation.
Flow or rainfall regime initial Split-flow pond: early-stage rainwater is by flow transmitter, then the motor operated valve of process unlatching, bleeds off from abandoned stream row of conduits; In the time that abandoned stream rainwater integrated flow arrives setting value, motor operated valve cuts out, and rain early-stage split-flow finishes, and clean rainwater starts to collect through rainwater collection collector.Rainfall regime just replaces flow transmitter by rainfall gauge, by rainfall gauge sensing amount of precipitation signal, control motor operated valve, and rainfall gauge need be placed in outdoor.This flow or rainfall regime initial Split-flow pond need measuring-signal to control motor operated valve, and the early-stage rainwater of turbidity zone impurity also likely twists or stops up motor operated valve shut-off block, causes fault; And motor operated valve is placed in moist environment for a long time, reliability and poor durability, so operation maintenance complexity, maintenance cost is high.
Summary of the invention
In view of this, the object of this invention is to provide the initial rain water drainage tank of top, a kind of pond rainfall automatic control, the rainwater clean early-stage rainwater high degree of contamination and middle and later periods is separated, solved the problems such as existing initial rain water drainage tank takes up an area greatly, operation maintenance is complicated, maintenance cost is high, easy obstruction, energy consumption.

In the present embodiment, described Water collecting tube 14 surroundings are provided with the stopping means 29 that prevents that Water collecting tube 14 from tilting, and prevent that the interior rainwater of Water collecting tube 14 from toppling, the control of impact to rain water drainage amount.
In the present embodiment, body 1 bottom, described drainage tank pond is provided with the Fen Shui cofferdam 30 around Water collecting tube 14, make Water collecting tube 14 form a dry environment around, described Fen Shui cofferdam 30 is provided with spilled water hole 31 near shunting pond 3 one side bottoms, and the rainwater overflowing from Water collecting tube 14 flows to shunting pond 3 from spilled water hole 31.
In the present embodiment, described time delay blow-down pipe 7 is provided with flow control valve 32, and described time delay blow-down pipe 7 entrances are provided with screen pack II 33, the open degree of adjust flux control valve 32, after rain is stopped, be stored in the rainwater in shunting pond 3, slowly discharge, emptying time can be controlled in 24 ~ 30 hours.
Body 1 top, described drainage tank pond is also provided with inspection manhole 34, and described inspection manhole 34 is provided with manhole cover 35, facilitates maintainer to safeguard equipment.
The initial rain water drainage tank of top, pond of the present invention rainfall automatic control, the initial stage of raining, rainwater enters into shunting pond 3 from rainwater water inlet flow channel 2, carry out the abandoned stream of early-stage rainwater by rain water drainage pipe 6, water-collecting tray 11 starts to collect the rainwater entering from rainwater-collecting mouth 4 simultaneously, is pooled in Water collecting tube 14 by header 16.The early-stage rainwater amount that described Water collecting tube 14 is collected is by formula calculating below: q=S1 × (h1+ h2), wherein q is the early-stage rainwater amount (Kg) of Water collecting tube 14 interior collections, h1 is initial Split-flow run-off (mm), generally get 2 ~ 5mm, h2 is that early-stage rainwater arrives the Rainfall runoff (mm) of drainage tank in during this period of time; In the time that the amount of rainfall of Water collecting tube 14 interior collections reaches q, Water collecting tube 14 falls, and traction lever 13 tilts, thereby closes flap valve 9, starts rainwater-collecting.Now completed initial Split-flow, the interior water level in shunting pond 3 starts to rise, and when water level exceeds behind water outlet cofferdam 10, rainwater enters rainwater collection collector 8 and collects for subsequent use.Because the interior water level in shunting pond 3 had flooded flap valve 9, flap valve 9 can bear certain water pressure, and rainwater is not as long as stop, pool inner water position can be maintained, lever 13 also can keep the high equilibrium state in low one side on one side so, and flap valve 9 is closed all the time, guarantees that rainwater-collecting normally carries out.
In rainfall, drop to bottom, pond after Water collecting tube 14 is collected set amount rainwater time, lower seal plate 24 clashes into bottom, and back down upper sealing panel 23, rainwater in Water collecting tube 14 can ooze out by bottom mozzle 21 overflow discharge orifices 22, after rain stops, Water collecting tube 14 tops no longer intake, spout hole 22 continues to ooze out rainwater, until the emptying (process of raining of the interior rainwater of Water collecting tube 14, even if the interior water level of Water collecting tube 14 declines, because bearing hydraulic pressure, flap valve 9 is greater than the weight that Water collecting tube 14 reduces, so the equilibrium state of lever 13 height can not be broken), simultaneously, the interior rainwater in shunting pond 3 is adjusted by flow control valve 32 by time delay blow-down pipe 7(mass rate of emission) slowly discharge, pool inner water position also slowly declines, flap valve 9 also slowly exposes until do not bear water pressure completely, the equilibrium state of lever 13 height is broken, Water collecting tube 14 will rise, lever 13 is got back to original parallel position, and open flap valve 9 by stay cord on assembly pulley 12, thereby get back to original state.For initial Split-flow and the rainwater-collecting of next rainfall ready.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although by with reference to the preferred embodiments of the present invention, invention has been described, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present invention that appended claims limits.
