The specific embodiment
With reference to figure 1, the combined-flow strainer 28 that the preferred embodiment of rain early-stage split-flow device of the present invention comprises abandoned stream executing agency 11 and is attached thereto.
With reference to figure 2～Fig. 3, described abandoned stream executing agency 11 comprises water inlet pipe 1, and water inlet pipe 1 links to each other with one section dirty chamber 18, is provided with hand basket grid 12 in cutting dirty chamber 18, and hand basket grid 12 comprises a hand basket and is positioned at hand basket top and coupled metallic grid.Inner surface at described hand basket is equipped with diafiltration mud barrier layer, and so that solid mud is intercepted in hand basket, liquid then can ooze out.Cut dirty chamber 18 and link to each other both shared casings with water (flow) direction control chamber 29.Water (flow) direction control chamber 29 is connected with abandoned stream pipe 8 with collecting pipe 6.Be provided with the plate valve switching mechanism in the water (flow) direction control chamber 29.Water (flow) direction control chamber 29 tops are provided with loam cake 13, in order to overhauling and removing contamination; The base plate 17 of water (flow) direction control chamber 29 tilts to cutting dirty chamber 18, is beneficial to dirt and flows in the hand basket grid 12 that cuts in the dirty chamber 18.The plate valve switching mechanism comprises and vertically is fixed on the plate valve axle 15 in the water (flow) direction control chamber 29 and is installed in valve plate 16 on the plate valve axle 15 that the big I of this valve plate 16 covers the mouth of pipe of collecting pipe 6 and abandoned stream pipe 8.Plate valve axle 15 links to each other with water (flow) direction control chamber 29 electrical header 14 outward.In water inlet pipe 1, be provided with water flow sensing unit 9 and water quality sensor 2, water flow sensing unit 9 all links to each other with a programmable logic controller 4 by control circuit with water quality sensor 2, this programmable logic controller 4 and coupled external control circuit are located in the waterproof electric control box, and link to each other with electrical header 14 by control circuit.Also be provided with the overall target sensor 3 that rains outside the waterproof electric control box, this overall target sensor 3 that rains links to each other with programmable logic controller 4 in the waterproof electric control box by control circuit.
With reference to figure 4～Fig. 5.Fig. 4 and Fig. 5 are respectively the front view and the vertical views of the combined-flow strainer 28 that links to each other with collecting pipe 6.Combined-flow strainer 28 comprises the cylindrical filter body 30 that is provided with strainer water inlet 19 and strainer delivery port 24, and its middle filtrator water inlet 19 links to each other with collecting pipe 6.Vertically fix the eddy flow filter plate 21 of an arc on the inwall of filter body 30, leave the gap between the diapire 31 of this eddy flow filter plate 21 and filter body 30, which is provided with a plurality of filter bores, strainer water inlet 19 and strainer delivery port 24 are positioned at a side of filter body 30 and are positioned on the same axis, make current enter and directly clash into a side of eddy flow filter plate 21 along the tangential direction of filter body 30.On the inwall of the back side of eddy flow filter plate 21 and the filter body 30 relative, be equipped with a plurality of downward-sloping deflection plates 25 with it.
Be provided with the hand basket 20 of removing contamination in the filter body 30 between strainer water inlet 19 and eddy flow filter plate 21, the inner surface of the hand basket 20 of removing contamination is equipped with diafiltration mud barrier layer.Filter body 30 tops at eddy flow filter plate 21 back sides are provided with a watertight shutter 22, are splashed to outside the filter body 30 to prevent the rainwater that sees through eddy flow filter plate 21.Diapire 31 and lower sidewall at filter body 30 are equipped with permeable hole 10, so that a small amount of rainwater infiltration.Diapire 31 outsides at filter body 30 are provided with three base anchors 26 in uniform way, are beneficial to it in underground installing and locating.
When under the sky, city during heavy or torrential rain, rainwater flows into the water inlet pipe 1 of rain early-stage split-flow device of the present invention by the underground pipeline of urban sewerage and drainage system, through the preliminary filtration of hand basket grid 12, wherein larger particles is filtered to cuts in the dirty chamber 18.The overall target of raining sensor 3, water flow sensing unit 9 and water quality sensor 2 are with rain rainfall and come the water water quality index to be sent to programmable logic controller 4 of detected rainwater throughput, the frequency of raining, initial stage, programmable logic controller 4 drives 15 rotations of plate valve axle according to the condition control electrical header 14 of program setting, at first make valve plate 16 close collecting pipe 6, abandoned stream pipe 8 is in the state of opening naturally at this moment, makes the rainwater of initial inflow flow into municipal blow-off line through abandoned stream pipe 8.Through after a while, testing result according to rain overall target sensor 3 and water flow sensing unit 9, when amount of precipitation reaches certain index in the early stage, programmable logic controller 4 control electrical headers 14 drive plate valve axle 15 and rotate, make valve plate 16 close abandoned stream pipe 8, this moment, collecting pipe 6 was in the state of opening, and the rainwater after preliminary the filtration flows in the strainer water inlet 19 of combined-flow strainer 28 through collecting pipe 6.
When rainwater flows into combined-flow strainers 28 to pass through strainer water inlet 19 than big speed, because the inflow direction of rainwater roughly is the tangential direction of arc eddy flow filter plate 21, so rainwater will be done the screw of the decline while rotating along eddy flow filter plate 21.Because eddy flow filter plate 21 is provided with a plurality of filter bores, so the part rainwater will flow to its dorsal part by the filter bores on the eddy flow filter plate 21, and watertight shutter 22 can prevent that the rainwater that sees through eddy flow filter plate 21 from splashing to outside the filter body 30.Then descended gradually by the dirt under 21 filters of eddy flow filter plate, finally drop down onto in the hand basket 20 of removing contamination, remaining rainwater is then from the bottom of eddy flow filter plate 21, walk around a plurality of downward-sloping deflection plates 25, finally together the flow through strainer delivery port 24 of combined-flow strainer 28 of the rainwater that sees through with the filter bores from eddy flow filter plate 21 enters the next stage rainwater collecting and treating system.Wherein deflection plate 25 plays the effect of filtering dirt equally.Diapire 31 and lower sidewall at filter body 30 are equipped with permeable hole 10, so that the storm seepage of fraction is in soil.Diapire 31 outsides at filter body 30 are provided with three base anchors 26 in uniform way, are beneficial to combined-flow strainer 28 in underground installation.
Cut the cleaning of all should regularly uncapping of hand basket grid 12 in the dirty chamber 18 and the hand basket 20 of removing contamination in the combined-flow strainer 28, to keep whole device water route unimpeded.
