The specific embodiment

Below in conjunction with Figure of description, the utility model is further described.

As Figure 1-Figure 5, a kind of rainwater flow-discarding device, comprise catch-basin 1 and the drainage tank 2 being connected with described catch-basin and collecting pit 3, described catch-basin 1 is connected with rainwater-collecting pipe network by the first pipeline, for the setting height(from bottom) that is communicated with described collecting pit 3 and the second pipe 5 of described catch-basin 1, higher than for being communicated with the 3rd pipeline 4 of 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.

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, when the height of water level in drainage tank 2 reaches the height of second pipe 5, rainwater starts to flow into the automatic flow abandoning that collecting pit 3 is realized 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, surpass after 24 hours, timer triggers water pump 7 rainwater in drainage tank 2 is drained, and is convenient to next abandoned stream; 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 timers 8, after rain stops, by rain stop sensor 9 triggering timing devices, start timing, 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.When occurring raining situation, the water level in metal dish 11 raises gradually, and when 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, raises rapidly the water level of center fast, thereby makes two holding wire conductings, has promoted the reaction speed of rain stop sensor.

The web height of metal dish 11 is 30mm, when there is heavy rain situation, guarantees 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, in order to avoid affect the rain in later stage, stops judgement.

Probe 12 be incense coil shape, has increased 12 the contact surface of popping one's head in, and guarantees when rainy situation occurs, pop one's head in 12 can with metal dish 11 fast conductings.

More than show and described basic principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
