In the present invention, the water reserve 30 of storm detention tank provides water inlet by water inlet 34, and 32-kickboard of floating drum 29 forms System can control the inflow of water reserve 30, (H2-H0) is the available depth of storm detention tank, by required catchment area Size, which is multiplied by 15mm, to be estimated to obtain, and when water level reaches H2, floating drum 32 is blocked by gear floating block 31 so as to avoid continuing floating, this When, kickboard 29 is exactly in horizontal level, and now water storage terminates, meanwhile, and the first sealing plate 33 that kickboard 29 vertically consolidates is just Water inlet 34 is sealed well, and the second sealing plate 26 completes the effect of dash jointly, ensures that later stage rainwater will not enter to early-stage rainwater Row dilution;The bottom of water reserve 30 is provided with DPK10.50.15 types submersible sewage pump 36 1, and submersible sewage pump 36 is provided with minimum depth of immersion H0, it is termination of pumping liquid level that H0 is set during installation, and design liquid level H1 corresponding to water capacity of water reserve 30 is arranged to opening for submersible sewage pump 36 Pump liquid position, the right upper portion of water reserve 30 are provided with UQK-03 types ball float level controller 37 1, controller 37 and submersible sewage pump 36 are connected in series by water proof wire, and the liquid level that the floating ball device inside controller 37 can be perceived in water reserve 30 changes so as to produce Raw electric signal, and submersible sewage pump 36 is passed the signal to control the keying of submersible sewage pump 36;Under original state, the H0 in water reserve 30 Highly it is lowest water level, after water inlet is continued, water level rises steadily, and when liquid level reaches and opens pump liquid position H1, submersible sewage pump 36 starts, By early-stage rainwater pumping into biological delaying basin, because the reservoir storage of biological delaying basin is limited, beyond the part of aquifer 39 again It can be back to by overflow returning pipe 35 in the water reserve 30 of storm detention tank, if rainfall is sufficiently large, the water level in water reserve 30 is not Disconnected to rise, when water level rises to H2, the first sealing plate 33 and the second sealing plate 26 seal the water inlet 34 of water reserve 30, store Pool 30 no longer intakes, and at this moment submersible sewage pump 36 is not due to arriving termination of pumping liquid level H0, therefore is still running, and and so on, initial stage Rainwater just constantly circulates between storage pond and delaying basin, all handled by biological delaying basin until early-stage rainwater and Discharged by collector pipe 41 and be detained cell system, when water level retracts H0 in water reserve 30, submersible sewage pump 36 is just stopped.
After water reserve 30 stores full water, in system in the cyclic process of rainwater, liquid level in water reserve 30 can under Drop, but because the liquid level in regulatory region 25 is still highest flood level, therefore ball float 28 is because buoyancy is still in neck 27 Overhead height, so the second sealing plate 26 still can play sealing function to water inlet 34, will not intake again to water storage Early-stage rainwater in area 30 is diluted.
In the present invention, after treating that rainfall stops, water inlet pipe 16 stops intaking to filter, and filter also stops to rainwater Storage pond is intake, after biological delaying basin ceaselessly handles rainwater and discharges it system, though the water level in water reserve 30 moves back Return H0 and submersible sewage pump 36 is stopped, but because the height of water level of regulatory region 25 remains at the tube top mark of the first overflow pipe 24 Eminence, i.e., water level is still flood level in regulatory region 25, therefore ball float 28 is under the buoyancy of water, still such that the second sealing plate 26 seal up water inlet 34, now, the small-sized discharge outlet 23 being installed on overflow pipe 24 start slowly by regulatory region 25 Water is drained, and when water level retracts the bottom hole water level of water inlet 34, ball float 28 can also drive the second sealing plate 26 to drop back to water inlet 34 Bottom hole liquid level, system returns to original state, and after rainfall starts next time, system can still reuse.
Described above is only the preferred embodiment of the present invention, it should be pointed out that:For the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
