The specific embodiment
As shown in Figure 1 to Figure 3, urban rainwater scrubbing of the present utility model harvests system, comprise main channel 1, harvest channel 2, shunt conduit 3, gate 6, gate opening/closing bucket 5, water cellar 7 and trashrack 4, described trashrack 4 is arranged on the entrance point of described main channel 1, described main channel 1 being divided into below of described trashrack 4 described shunt conduit 3 and described in harvest channel 2, the described width that harvests channel 2 is 3 times of described shunt conduit 3 width, described harvesting sets gradually described gate 6 and described water cellar 7 on channel 2, at the bottom of canal before described gate, be provided with end bank, described gate bottom is provided with a rubber friction pad, described gate opening/closing bucket 5 is arranged on described shunt conduit 3, described gate opening/closing bucket 6 is suspended in the below of described shunt conduit 3 by connection cord 55, the bottom of described gate opening/closing bucket 5 has an aperture 54, and described connection cord 55 is connected with described gate 6 by the pulley 52 that is arranged on described shunt conduit 3 tops.
Urban rainwater scrubbing of the present utility model harvests system, is extension, side drain, city, and it makes full use of roadside, city or gutter, square, and the entrance point of main channel 1 connects gutter.
Shunt conduit 3 is the early-stage rainwater channel of flowing through, i.e. the dirty shunt conduit of rain, for the shunting processing of early-stage rainwater; After shunting, harvest channel 2 for the later stage rainwater channel of flowing through, for later stage rainwater-collecting.The width of shunt conduit 3 is narrower than the width that harvests channel 2, and object is to guarantee that most rainwater is collected through harvesting channel 2 after gate 6 is opened, a small amount of rainwater shunt conduit 3 of flowing through, the opening that guarantees to collect gate 6.The canal slope of main channel entrance, to reduce the erosion effect of rainwater to channel.Sewage double-edged fine-toothed comb is installed on the road surface on entrance, and the larger rubbish of volume of bringing into can tentatively tackle rainwater conflux time, as leaf, polybag, the scraps of paper etc.Entrance point in main channel 1 is installed " extensively " word trashrack, the fritter light refuse that enters entrance point (is put down with ground) to " extensively " trashrack platform place by punching under hydro-flow thrust and buoyancy, being convenient to cleaner removes, reduce the chance of rubbish obstruction trashrack, kept the mistake water-based that trashrack is good and collected Rainwater Quality good." extensively " word trashrack with at the bottom of canal, become 30 ° of angles.At the bottom of canal before described gate, be provided with end bank, the silt being used in interception collection rainwater.
Gate opening/closing bucket 5 is early-stage rainwater collecting vessel, be positioned on shunt conduit 3, as shown in Figure 1: gate opening/closing bucket 5 diameters are D, be suspended in the below at shunt conduit 3 places by connection cord 55, at the top of shunt conduit 3, a horizontal iron staff 51, the little ring that a diameter is d is fixed in the centre position of iron staff 51, build pulley 52, connection cord 55 connects gate opening/closing bucket 5 by little ring.The bottom of gate opening/closing bucket 5 has an aperture 54, for seepage rainwater.Before gate 6 is opened, shunt conduit 3 flows are larger, a large amount of early-stage rainwaters shunt conduit 3 of flowing through enters gate opening/closing bucket 5, far away faster than seepage speed, amount of rainfall in gate opening/closing bucket 5 constantly increases, the pulling force to connection cord 55 producing therefrom constantly increases, until starting gate 6 is collected later stage rainwater.After rainfall stops, in gate opening/closing bucket 5, there is no the supply of rainwater, the gravity of gate opening bucket 5 can constantly reduce along with the seepage of aperture 54, and the pulling force of connection cord 55 also can constantly reduce, until rain leakage is complete.Now, 55 of connection cords bear the pulling force that staving 53 itself is with, and this pulling force is less than gate 6 conducts oneself with dignity, and under the moment loading that gate 6 produces at self gravitation, closes.
