The course of work of above-mentioned combined system underground Rainwater Storage Tank is as follows:
During fine day, first Hydro-automatic gate 5, second Hydro-automatic gate 7 is closed condition, the discharge of sewage entered from water inlet pipe 3 is less than the maximum throughput of Wastewater Treatment Plant, and sewage directly flows through the first Buffer Pool 1 and the second Buffer Pool 2, is discharged into Wastewater Treatment Plant's process from drip chamber 17 by gutter 18.Due to tube connector 13 overhead height lower than or flush in the second Buffer Pool 2 base plane place height, now sewage all flows at the lower recess of the first Buffer Pool 1 and the second Buffer Pool 2, can not enter in storage pond by self-cleaning horizontal grate 12, in aquifer reserve pond 6, each equipment all can not operate.
At the rainfall initial stage, early-stage rainwater flow and discharge of sewage sum are less than the maximum throughput of Wastewater Treatment Plant, and combined sewage is directly discharged into Wastewater Treatment Plant's process too.Along with the carrying out of rainfall, early-stage rainwater flow and discharge of sewage sum are greater than the maximum throughput of Wastewater Treatment Plant, and now maximum stream flow current-limiting apparatus ensures to enter the flow of Wastewater Treatment Plant is still the maximum throughput of Wastewater Treatment Plant.So far the second Hydro-automatic gate 7 is in closed condition always, anhydrous in aquifer reserve pond 6, anhydrous in float chamber 705, balancing weight 709 is pulled to the top place by pulley 710, pulley 711 by float 706, as shown in Figure 7, water inlet 707 is in opening always, when the water level of the second Buffer Pool 2 constantly rises, the water level of the second Buffer Pool 2 rises to the water inlet water level of water inlet 707, namely when the second Hydro-automatic gate opens water level 20, current pour into rapidly buoyancy tank room 704, and buoyancy tank 702 floats and drives gate 703 to open, as shown in Figure 8.Early-stage rainwater enters aquifer reserve pond 6 after self-cleaning horizontal grate 12 is tackled.Water level when aquifer reserve pond 6 rises gradually, to the water inlet water level of float chamber 705, namely during the maximum impounded water levels in aquifer reserve pond height 21, float 706 floats, balancing weight 709 by wire rope 712 and float 706 link decline after block water inlet, as shown in Figure 9, in buoyancy tank room 704, water slowly flows out from weep hole 708, gate 703 is driven to close after float 702 sinks, as shown in Figure 10.
After second Hydro-automatic gate 7 is closed, the water level of the second Buffer Pool 2 continues to rise, when the water level of the second Buffer Pool 2 rises to the first Hydro-automatic gate unlatching water level 22, during the water inlet water level of i.e. the first Hydro-automatic gate 5 buoyancy tank room, first Hydro-automatic gate 5 is opened, and later stage rainwater is discharged into natural water by natural water floss hole 4.
When amount of precipitation reduces or stops, when second Buffer Pool 2 flow is less than the maximum throughput of Wastewater Treatment Plant, namely the first liquid level sensor 15 of maximum stream flow current-limiting apparatus and the second liquid level sensor 16 coordinate and sense that the second Buffer Pool 2 flow is less than maximum stream flow, maximum stream flow current-limiting apparatus opens submersible sewage pump 8 by control unit, submersible sewage pump 8 starts the rainwater in aquifer reserve pond 6 to be extracted into the second Buffer Pool 2, is discharged into Wastewater Treatment Plant processes by gutter 18.
Water level in 3rd liquid level sensor 11 Real-Time Monitoring aquifer reserve pond 6.When aquifer reserve pond 6 water level decreasing, signal is transferred to flusher 9 by control unit by the 3rd liquid level sensor 11, the intelligent ejector of flusher 9 starts to stir, the part silt be deposited at the bottom of pond is taken away together by rainwater, when the water level decreasing in aquifer reserve pond 6 is to when being shown at the bottom of pond, signal is transferred to flusher 9 by control unit by the 3rd liquid level sensor 11, intelligence ejector starts to rinse at the bottom of pond, aquifer reserve pond 6 bottom field is gathered by high-definition camera 10 after having rinsed, and this picture signal is passed to control unit, control unit carries out the division of intelligent net region at the bottom of storage pond pond, if there is stain bottom aquifer reserve pond 6, then according to the coordinate relation of stain position and flusher 9, control flusher 9 water pump water outlet lift and rotate required angle, flusher 9 pairs of stain positions are made to carry out point-to-point cleaning, aquifer reserve pond 6 is rinsed well.Whole flushing process is without the need to external water source, and developing result is better than flap type and rinses door and waterpower tipping bucket, and in water, sediment charge is little, and can not deposit Buffer Pool and pipe duct.
The above; be only detailed description of the invention of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
