Wherein: 1: housing; 2: water inlet pipe; 3: abandon water pipe; 4: outlet pipe; 5: tumbler; 6: locating part; 7: screen pack; 8: drain gully; 9: manhole cover.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described, and only for explaining the present invention, and can not limitation of the present invention be interpreted as.
As shown in Figure 1, a kind of rain water collecting system initial Split-flow device, for collecting the rainwater of roof or road surface, it comprises housing 1, and water pipe 3 abandoned by water inlet pipe 2, outlet pipe 4, revolving part 5, locating part 6, screen pack 7 and drain gully 8.The described U-shaped hollow body of housing 1, housing 1 top seal and side, top arranges water inlet, the top of housing 1 is interval with manhole cover, water inlet connects water inlet pipe 2, housing 1 bottom center arranges abandoned stream mouth, abandoned stream mouth connects abandoned stream pipe 3, housing 1 bottom surface sets out the mouth of a river relative to the different limit of water inlet, delivery port connects outlet pipe 4, the mouth of pipe of outlet pipe 4 arranges screen pack 7, the U-shaped lower semicircular axle center place of housing 1 arranges rotating shaft, rotating shaft is socketed the fan-shaped tumbler 5 rotated around the shaft, bottom housing 1 be and the fan-shaped arc agreed with, the upper end of tumbler 5 is connected with rotating shaft, the lower end of tumbler 5 contacts with housing 1 bottom interior wall and seals waterproof, the lower end size of tumbler 5 is greater than abandoned stream pipe 3 and outlet pipe 4 size, housing 1 lower space is separated into abandoned stream district and exhalant region by tumbler 5, delivery port diameter is not less than abandoned stream mouth diameter, described abandoned stream pipe 3 is positioned at housing bottom, the mouth of pipe of abandoned stream pipe 3 is positioned at the bottommost that tumbler 5 swings camber line, when namely there is no liquid in housing 1, tumbler 5 remains static, and the mouth of pipe of shutoff abandoned stream pipe 3, described outlet pipe 4 is arranged at the different limit relative to housing inlet, described delivery port is arranged the locating part 6 stoping tumbler 5 to cross effluent pipe mouth 4.
Its middle shell 1 is the bottom shutoff made from the sheet material that 0.8cm is thick, upper cover gab, and overall U-shaped, top is rectangle, and bottom be semicircle, and the casing of top and the bottom UNICOM, upper opening place is provided with manhole cover 9.Water inlet pipe 2, perpendicular to upper transverse plane, is partial to housing side; Abandoned stream pipe 3 is positioned at housing lower end curved bottom, and perpendicular to transverse plane on housing, outlet pipe 4 is arranged at the different limit relative to housing inlet.The tubular that the sheet material that water inlet pipe 2, abandoned stream pipe 3 and outlet pipe 4 are 1mm is made.Water inlet pipe 2 vertically extend in housing 1, and diameter is 300mm, and water inlet pipe 2 is divided into the part outside housing and the part in housing, and the part outside housing is for connecting rainwater collection collector, and enclosure interior is divided into drain gully 8.The partial-length that water inlet pipe 2 is positioned at outside housing 1 is 300mm, and the partial-length being positioned at housing 1 is 100mm.Abandoned stream pipe 3 lower end connects sewer pipe, and abandoned stream pipe 3 upper end is connected on housing 1, and abandoned stream pipe 3 diameter is 100mm, and length is 200mm.Under nature anhydrous state, the mouth of pipe of shutoff plug abandoned stream pipe 3 bottom revolving part 5; Outlet pipe 4 is positioned at the different limit of water inlet pipe 2, and the diameter of outlet pipe 4 is 300mm, and length is 200mm, and one end of outlet pipe 4 is connected on housing 1, and the other end connects rainwater collection pool.
Housing bottom is divided into abandoned stream district and exhalant region by revolving part, at Rainwater Initial, rainwater, from drain gully 8 place's vertical drop, flows to abandoned stream district bottom housing 1 along water inlet direction, exhalant region does not have rainwater, revolving part 5 both sides mineralization pressure is poor, and revolving part 5 rotates to anhydrous exhalant region, and revolving part 5 can open abandoned stream pipe 3 mouth of pipe after rotating, also the mouth of pipe of outlet pipe 4 is blocked, under the effect of locating part 6, revolving part 5 can only rotate to spacing place, and early-stage rainwater is flowed out by abandoned stream pipe 3.When amount of rainfall increases, revolving part 5 abandoned stream district rainwater liquid level constantly raises, after liquid level exceedes axis of rotation height, rainwater flows into the anhydrous exhalant region of revolving part 5 opposite side, and along with rainwater increases, revolving part pressure at both sides balances gradually, revolving part 5 returns to initial position, while blocking abandoned stream pipe 3, open outlet pipe 4, the later stage, clean rainwater flowed into reservoir through outlet pipe 4, reached the object of collecting rainwater.
The rain water collecting system initial Split-flow device of the present embodiment can be embedded in underground, connects rainwater collection collector, sewer pipe and rainwater collection pool.Drop to housing bottom at the rainwater-collecting initial stage through the rainwater of drain gully 8, rainwater is exerted pressure to revolving part 5, closes outlet pipe 4, realize the abandoned stream of rainwater while revolving part 5 starts abandoned stream pipe 3 to outlet pipe 4 one sideway swivel.When after the initial stage, rainwater quantitative change is large, rainwater liquid level is increased beyond axis of rotation height, rainwater flows into the anhydrous side of revolving part 5, ever-increasing rainwater balance rotating part 5 pressure at both sides, and revolving part 5 returns to initial position, open delivery port 4, close abandoned stream pipe 3, rainwater then flows out from outlet pipe 4, realizes the collection of rainwater.When rainy end, amount of rainfall diminishes to stopping, and revolving part 5 pressure at both sides is not identical, can open abandoned stream pipe 3 after disequilibrium, drains residue rainwater by abandoned stream pipe 3.
Wherein refer under normality under the state of not collecting rainwater, relative to the axle center that it rotates, revolving part 5 naturally droops, and blocks abandoned stream pipe 3, and now outlet pipe 4 is in UNICOM's state.
The inner side being positioned at outlet pipe 3 in housing 1 is provided with filter screen 7, can play the effect of further impurity screening.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
