Description
Technical field
The utility model relates to a kind of drainage, specifically a kind of divided-flow rainwater automatic defeating device.
Background technology
Urban development is run off a large amount of rainwater resources, and simultaneously, rainfall runoff washes away again a large amount of Non-point Source Pollutants and brings urban water system into, causes the deterioration of Urban Water Ecological Environment.It is the key issue that Urban Rainwater Runoff Pollution is controlled and rainwater resource utilizes that with serious pollution early-stage rainwater runoff is implemented effectively to control.Because rainfall has randomness and noncontinuity, the pollutant in urban runoff is mainly to concentrate in the amount of precipitation at initial stage, makes people be difficult to effectively control to the control of city early-stage rainwater.Often adopt at present very large stormwater tank dam and dispose early-stage rainwater, but need very high civil engineering costs or floor space, usually be difficult to carry out in city.
Summary of the invention
In order to overcome deficiency of the prior art, provide a kind of divided-flow rainwater automatic defeating device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of divided-flow rainwater automatic defeating device, comprise one section sewer, side at sewer arranges diffluence room, the bottom surface of diffluence room is lower than the bottom surface of sewer, the bottom surface of sewer and the side of adjacent diffluence room have pore to be communicated with the abandoned stream pipe, the pore place of diffluence room side arranges the emptying flashboard, between sewer and diffluence room, partition is arranged, and the locally connected cut off, on cutting off, establish bearing, mechanism for automatically switching is arranged on bearing; Its mechanism for automatically switching comprises the lever be supported on bearing, and the lever two ends connect respectively the floating drum that is positioned at diffluence room and the cover plate that is positioned at pore place, sewer bottom surface after connecting connecting rod.Two fulcrums are arranged on above-mentioned bearing, and two fulcrum upper supports have framed bent shape double lever, and double lever connects respectively floating drum and cover plate through double link.Between above-mentioned sewer and diffluence room, by split-flow baffles, the shunting seam, shunt passage aisle or tap hole and be communicated with.Above-mentioned split-flow baffles is the adjustable flow distributing dividing plate.Above-mentioned lever is in-line, herringbone or shoulder pole type.The alternative of above-mentioned floating drum is ball float or floating block.The dischargeable capacity of above-mentioned diffluence room only accounts for the part to tens of total abandoned stream amount/mono-.
The beneficial effects of the utility model: the side at sewer arranges diffluence room, in the mode of shunting, only uses tens of/mono-initial stage rainfall to implement the control to whole early-stage rainwater amounts; And by simple and effective mechanism for automatically switching, random rainfall is controlled automatically, solved due to the unworkable difficult problem of rainfall randomness equipment.Do not need manual operation can realize exactly the amount of damming of every rainfall is controlled automatically; can effectively control the pollution of the early-stage rainwater runoff of the various gathering surfaces generations in city; effectively protect the urban water system ecological environment, safety, reasonably utilize urban rainwater resources.Only with conventional rainwater dam pond or storage pond volume tens of/mono-, can realize controlling the runoff pollution rate of load condensate and reach more than 80%.Civil engineering costs or occupation of land can reduce to tens of/mono-.

The specific embodiment
In the drawings, a kind of divided-flow rainwater automatic defeating device, comprise one section sewer 7, in the side of sewer, diffluence room 8 is set, the bottom surface of diffluence room is lower than the bottom surface of sewer, and the bottom surface of sewer and the side of adjacent diffluence room have pore to be communicated with abandoned stream pipe 6, and the pore place of diffluence room side arranges emptying flashboard 10, between sewer and diffluence room, partition is arranged, and be communicated with by shunting seam 9 in the part cut off.On cutting off, establish bearing 5, mechanism for automatically switching is arranged on bearing; Bearing 5 is two fulcrums or single fulcrum, and two fulcrum upper supports have the framed bent shape double lever 3 of in-line, herringbone or shoulder pole type, and double lever connects respectively floating drum 1 and cover plate 2 through double link 4,4.Floating drum 1 can substitute with ball float or floating block.The size dimension of floating drum and cover plate is according to calculative determinations such as selection, weight, buoyancy and leverage power.Each parts should meet intensity and requirement for anticorrosion.
Control the process of early rainwater automatic flow abandoning amount: determine at first exactly the initial stage rainfall that need to dam; Reasonably designing and calculating, reach less equipment investment scale and easy operation control system, and contaminated rainwater implemented effectively to control.Pollutant in clear and definite urban runoff is mainly to concentrate in the amount of precipitation at initial stage,, according to gathering ground character and degree of contamination, then calculate according to the size of charge for remittance effective area, the runoff coefficient of gathering ground, the initial rainfall amount that needs abandoned stream and diverting coefficient the early-stage rainwater total amount (m3) that need to dam.According to number, ground condition and the draining scale of concrete regional pollutant, determine that the dischargeable capacity of diffluence room only accounts for the shunt ratio of total abandoned stream amount, adjustable angle is set in Storm Sewer System split-flow baffles is shunted.By shunting part out, to the cover plate that tens of/mono-amount of rainfall drives by mechanism for automatically switching, realize that automatically the Initial Runoff total amount that all need are dammed controls.Bearing is fixed on the partition built-in fitting between diffluence room and sewer, then with movable axis, lever, connecting rod, floating drum, cover plate is connected, and be fixed on bearing.To road rain water, grid preferably is set removes large rubbish before sewer, the shunting seam is also unsuitable too small, with anti-clogging; Sewer before the shunting seam should have one section straight line stable section, with the uniformity of holding tube channel water stream and shunting.Before rainfall, vacant in diffluence room, the cover plate of sewer is in opening, as shown in Figure 2.After rainfall started, the early-stage rainwater of part shunting entered diffluence room, and the water level in diffluence room rises gradually, and floating drum also rises thereupon, by the cover plate in connecting rod and lever drives sewer, descends simultaneously.Before at the bottom of cover plate drops to canal, most of early-stage rainwater polluted enters community or municipal sewage piping by the abandoned stream pipe, enters sewage disposal system.When the early-stage rainwater that enters diffluence room reached amount of calculation, cover plate descended and puts in place, automatically the abandoned stream pipe mouth of pipe is covered, and cover plate is in closed condition, as shown in Figure 3.The rainwater that later stage is clean or rainfall not long follow-up rainfall break time enter Rainwater collection system or enter water body.After rainfall stops really, open the emptying flashboard, device completes a cycle of operation, gets back to original state.
