Abstract
The invention discloses a rainwater flow discarding device. The rainwater flow discarding device comprises a rainwater well, a flow discarding pool and a collecting pool, wherein the flow discarding pool and the collecting pool are communicated with the rainwater well. The rainwater well is communicated with a rainwater collecting pipe network through a first pipeline, the mounting height of a second pipeline used for enabling the collecting pool and the rainwater well to be communicated is larger than that of a third pipeline used for enabling the flow discarding pool and the rainwater well to be communicated, a water pump and a timer electrically connected with the water pump are arranged on the flow discarding pool, and the flow discarding pool is further provided with a rain stopping sensor electrically connected with the timer. Due to the fact that the mounting height of the water inlet pipeline of the flow discarding pool is different form that of the collecting pool, automatic flow discard is achieved, the function that flow discard is not carried out in the situation that rain falls again within 24 hours after rain stops is achieved through the rain stopping sensor and the timer, optimization of rainwater collecting is achieved, and collecting efficiency is improved.
Description
Technical field
The present invention relates to a kind of rainwater flow-discarding device, belonged to rainwater processing technology field.
Background technology
Advocating today of sustainable development, how can effectively collect rainwater and be and again utilize is the focus of instantly studying.For the rainy initial stage, in possible air, there are a large amount of dusts, also there are a large amount of dust, foreign material etc. in ground or surface, house, therefore for rainwater-collecting, need to be by the rain water drainage at initial stage.And in the time occurring that discontinuity is rained, research shows that if being spaced apart within 24 hours between two rain, the second rainy early-stage rainwater still can be collected as clean rainwater.
All carry out abandoned stream and existing rainwater flow-discarding device is normally at every turn rainy, wasted to a certain extent rainwater resource.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further illustrated.
As Figure 1-Figure 5, a kind of rainwater flow-discarding device, the drainage tank 2 and the collecting pit 3 that comprise catch-basin 1 and be connected with described catch-basin, described catch-basin 1 is connected with rainwater-collecting pipe network by the first pipeline, higher than the 3rd pipeline 4 for being communicated with described drainage tank 2 and described catch-basin 1, and on described drainage tank 2, be provided with the timer 8 that water pump 7 and described water pump 7 are electrically connected for the setting height(from bottom) that is communicated with described collecting pit 3 and the second pipe 5 of described catch-basin 1.
The difference of the inlet channel setting height(from bottom) by drainage tank 2 and collecting pit 3, make the rainwater inflow drainage tank 2 at rainfall initial stage realize abandoned stream, in the time that the height of water level in drainage tank 2 reaches the height of second pipe 5, rainwater starts to flow into collecting pit 3 realizes the automatic flow abandoning of rainwater.
The rain water drainage amount of this device is V=F*H, and wherein F is the collective area of the rainwater-collecting pipe network that is communicated with catch-basin 1, and H is abandoned stream thickness, and for general roofing, abandoned stream thickness is 0.003m, and for square road etc., the thickness of abandoned stream is 0.005m.The volume of drainage tank 2 is consistent with rain water drainage amount V.
After rainfall stops, start timer, exceed after 24 hours, timer triggers water pump 7 rainwater in drainage tank 2 is drained, and is convenient to next abandoned stream; When in 24 hours, there is rainfall for the second time, timer zero clearing, reclocking after rainfall for the second time stops, reciprocal successively, abandoned stream not while there is rainfall situation again in 24 hours, has realized the optimization of rainwater-collecting, has improved collection efficiency.
On drainage tank 2, be also provided with the rain stop sensor 9 being electrically connected with described timer 8, utilize rain stop sensor 9 to control the timing of timer 8, after rain stops, start timing by rain stop sensor 9 triggering timing devices, thereby realized the automatic control of timer 8.
Rain stop sensor 9 comprises metal dish 11 and the probe 12 of upper surface open, described probe 12 is fixed on by insulating supporting 13 on the bottom surface of described metal dish 11, also comprises the first signal line 15 being connected with described metal dish 11 and the secondary signal line 14 being connected with described probe 12.In the time occurring raining situation, the water level in metal dish 11 raises gradually, and in the time that water contacts with probe 12, two are switched on signal, thereby to external device transmission of signal, to show being at present rainy situation; Metal dish 11 bottom surfaces are provided with weep hole, and described weep hole place is provided with ball valve 17, and when the rain stopping time, delivery port can be discharged the water in metal dish 11 fast, two holding wires is disconnected, to show that being at present rain stops situation.
Weep hole top is provided with filter screen 16, and filter screen 16 is 30 order stainless steel filtering nets, utilizes filter screen 16 to avoid foreign material to stop up weep hole, causes the water in metal dish 11 cannot discharge and equipment cannot normally be worked.
Metal dish 11 is funnel-form, and described probe 12 is positioned on the center of described metal dish 11.Adopt funnelform metal dish 11, once there is the situation of raining, the center to metal dish 11 by rainwater-collecting fast, raises rapidly the water level of center, thereby makes two holding wire conductings, has promoted the reaction speed of rain stop sensor.
The web height of metal dish 11 is 30mm, in the time there is heavy rain situation, ensures that the water in metal dish 11 can overflow, and makes its water retention capacity not too large, when the rain stopping time, can get rid of as soon as possible by weep hole, stops judgement in order to avoid affect the rain in later stage.
Probe 12 be incense coil shape, has increased 12 the contact surface of popping one's head in, and ensures in the time that rainy situation occurs, pop one's head in 12 can with metal dish 11 fast conductings.
More than show and described general principle of the present invention, principal character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
