That describes that interflow of the present invention pipeline primary rainwater closure stores heat-extraction system in detail below in conjunction with accompanying drawing stores discharge method.
During dry season, the sewage being entered shunting well by interflow pipeline dams through cut-off groove 30, the space that the inwall that sewage flows into L-type plate, the second compartment wall 22 and flow control room 22a through cut-off groove 30 surrounds, after through sewage transition conduit 32(or sewage transition conduit 32 '), sewage branch pipeline 14 enters drainage 13, enter Wastewater Treatment Plant finally by drainage 13 and process.
During rainfall, the first rain being entered shunting well by interflow pipeline dams through cut-off groove 30, the space that the inwall that first rain flows into L-type plate, the second compartment wall 22 and flow control room 22a through cut-off groove 30 surrounds, after through sewage transition conduit 32(or sewage transition conduit 32 '), sewage branch pipeline 14 enters drainage 13, enter Wastewater Treatment Plant finally by drainage 13 and process.
When rainfall exceedes the combined closure system of cut-off groove 30 originally, first rain flows through cut-off groove 30 and enters retaining room 4 by first rain import 40 and in the passage room 22b that is communicated with it, then enter the long line retaining pipeline 50,51 be communicated with passage room 22b with retaining room 4, to store.In the process, along with the increase of early-stage rainwater flow and water level increase, the flow also corresponding increasing in the space that the inwall flowing into L-type plate, the second compartment wall 22 and flow control room 22a surrounds, overflow is produced when the maximum inflow-rate of water turbine in the space that the inwall exceeding L-type plate, the second compartment wall 22 and flow control room 22a surrounds, the water yield is overflowed from the side plate top of L shaped plate 31, enters flow control room 22a.
When the water storage level in the 22b of passage room is lower than water level in the 22a of flow control room, non-return flap valve 24a opens, rainwater admission passage room 22b in the 22a of flow control room, when the water storage level in the 22b of passage room is higher than water level in the 22a of flow control room, non-return flap valve 24a closes, along with L-type plate, the continuous spilling of rainwater in the space that the inwall of the second compartment wall 22 and flow control room 22a surrounds, in the 22a of flow control room, water level constantly rises, when after the circular keg float 35 that water level exceedes bottom kickboard 33, keg float 35 rises gradually under buoyancy, kickboard 33 is driven to lift gradually, until by sewage transition conduit 32(or sewage transition conduit 32 ') port shutdown, make L-type plate, sewage in the space that the inwall of the second compartment wall 22 and flow control room 22a surrounds is no longer by sewage transition conduit 32(or sewage transition conduit 32 '), sewage branch pipeline 14 enters drainage, thus avoid excessive rainwater to enter proper drainage that drainage affects drainage.
When storing in retaining room 4 completely, first rain import 40 is closed by removable cover device, flow through cut-off groove 30 by the interflow pipeline follow-up cleaner rainwater entered in shunting well, top, retaining room 4 is discharged by delivery port 20b, finally flow into river course, thus the early-stage rainwater avoiding heavy contamination flows into river course, pollutes river course; Meanwhile, it also avoid interflow water flow of pipeline larger time impact that drainage is caused, ensure that the proper drainage of drainage.
The rainfall later stage, displacement in the pipeline of interflow reduces, water level decreasing, the discharge reduction in the space that the inwall flowing through cut-off groove 30 and L-type plate, the second compartment wall 22 and flow control room 22a surrounds, when the water level of accommodation space is lower than sewage transition conduit 32(or sewage transition conduit 32 ') behind the top of port, circular keg float 35 drives kickboard 33 to decline gradually, finally makes kickboard 33 drop on baffle plate 34, recovers the sewage current floe condition of L shaped plate 31.
In retaining room 4 and water storage system 5, the first rain of savings is slowly retracted into drainage 13 through water-break system.Because the early-stage rainwater amount entering long line retaining pipeline 50,51 is greater than the water-break amount of water-break system, therefore, the long line retaining pipeline be communicated with each shunting well can be stored full in the rainfall incipient stage, after the rain, early-stage rainwater amount can be delayed from water-break system again and be retracted into drainage 13, when not affecting Wastewater Treatment Plant and running, a large amount of early-stage rainwaters is processed.
Although above-mentioned to invention has been detailed description; but the present invention is not limited thereto; those skilled in the art can principle according to the present invention modify, and therefore, all various amendments carried out according to principle of the present invention all should be understood to fall into protection scope of the present invention.
