The specific embodiment

As shown in Figure 1 to Figure 3, energy saving and environment friendly urban rainwater gathering system of the present invention, 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 being arranged on the pulley 52 at described shunt conduit 3 tops.

Urban rainwater gathering system of the present invention, 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, and the dirty shunt conduit of rain, processes for the shunting 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 in the time of can tentatively tackling rainwater conflux, 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, reduced 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, by connection cord 55, be suspended in the below at shunt conduit 3 places, 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 deadweights, under the moment loading that gate 6 produces at self gravitation, closes.

Gate 6 is arranged at and harvests on channel 2, as shown in figures 1 and 3, the thick ▽ of gate 6, density is ρ, high h0, wide b0, can obtain its quality is m0=ρ b0h0 ▽.In gate 6 lower right corner, fixing a diameter is the little ring 61 of gate of d.At the canal wall that harvests channel, a truckle is installed, a same truckle is installed on the canal wall of shunt conduit 3, described connection cord 55, through described pulley 52 and this two truckles, is connected on the little ring 61 of described gate.When rainwater enters in the early stage, in order to prevent gate 6 from opening too early, do not reach the object of shunting under rainwater pressure, in described gate bottom, be provided with a rubber friction pad, so that frictional force to be provided.

After gate 6 is opened, shunt conduit 3 moderate rain discharges diminish, and a large amount of rainwater enters in water cellar 7 and is collected by harvesting channel 2.Although flow through, the rainwater flow of shunt conduit 2 has diminished, and is still greater than the flow of seepage, and continuing increases the pulling force on connection cord 55, maintains gate 6 and reaches equilbrium position.After precipitation stops, in gate opening/closing bucket 5, the amount of rainwater can reduce gradually due to the seepage of aperture at the bottom of bucket 54, and therefore, the pulling force on connection cord 55 diminishes, and gate 6 can return to initial position under the Action of Gravity Field of self, closes.

Water cellar 7 is provided with unsteady drain cover, its objective is and realizes at the completely rear self-closed water cellar of water cellar water, makes rainwater no longer enter this water cellar 7, but flows through or flow out from the floating head of water cellar 7.Unsteady drain cover be one to the similar thin plate of the interior geometric form of water cellar 7, density is less than the density of water.When the rainwater of collecting enters water cellar 7, unsteady drain cover can float along with increasing of the water yield in cellar for storing things, when rainwater-collecting is full, drain cover rises to and harvests channel 2 bottoms, the breach area on cellar for storing things is large than channel for drain cover, just floated to be squeezed to and harvested channel 2 bottoms, at the bottom of serving as canal, make rainwater after this flow to downstream along harvesting channel 2.Due to water cellar 7 tops higher than canal at the bottom of, can prevent that water cellar 7 water overfill are damaged by frost in the winter time.Meanwhile, can continue to arrange same water cellar below at this water cellar 7, continue to collect rainwater, realize rainwater series connection and collect.

This system adopts " extensively " word trashrack, and the rubbish of interception is washed on platform, is convenient to cleaner and removes; The early-stage rainwater part flow arrangement consisting of shunt conduit 3 and gate 6 that can automatic open and close, can realize the shunting abatement processes to early-stage rainwater, makes initial stage high pollution rainwater can not enter water cellar 7, guarantees that water cellar 7 influent qualities are good; By designing unsteady drain cover, after making rainwater hold completely, can automatically along channel, flow into next water cellar in a water cellar, realize rainwater series connection and collect, reach and collect more rainwater and the full antifreeze object of water cellar water.
