Description

Flood control system
Technical field
The present invention relates to drainage system, in particular to a kind of flood control system.
Background technology
With increasing of urban atmospheric pollution and ground pollution, rainwater runoff pollution is further serious, and especially pollutant is relatively Many early-stage rainwaters, according to investigations, the pollutant index peak of some regional early-stage rainwaters is to be significantly larger than typical urban life Sewage alive, it is very necessary for being therefore collected process for first rain;In addition, when precipitation or continuous precipitation, easy shape Become ponding, lead to cities and towns waterlogging.
At present, usually rainwater whole process is entered natural water, this mode can cause certain water pollution.With ring Protect the reinforcement of consciousness and the development of rainwater catchment system technology, in drainage system, start consideration and take the rain such as Vatch basin flood to adjust Control facility early-stage rainwater is dammed, early-stage rainwater is delivered to sewage treatment plant and carries out purified treatment, then again will in after Phase rainwater is directly discharged in natural water.Existing flood control facility suffers from the drawback that:1) there is delayed, appearance to flood control Easily form ponding, lead to cities and towns waterlogging to happen occasionally;2) fuzzy to the control of primary rainwater closure flow extensive, if first rain separates Insufficient, pollution will be produced to natural water, if the just rain that dams is excessive, will result in the wave of storm detention tank limited resources Take and irrational use, in addition Sewage Plant treating capacity is required also very high.
Content of the invention
Present invention aim to providing a kind of flood control system, this system can be regulated and controled in time to rainwater, be had Effect prevents cities and towns waterlogging and early-stage rainwater, and directly discharge pollutes.
For achieving the above object, the technical solution used in the present invention is:A kind of flood control system, including draining passageway, Described draining passageway left end is provided with rainwater import, and right-hand member is provided with pending rainwater outlet, is provided with flood discharge on front side of described draining passageway Mouthful, it is provided with flood discharge at described floodwater releasing port and control weir gate;Be provided with side by side from left to right on rear side of described draining passageway the first storage pond and Second storage pond, is provided with the first flow structure, described first storage pond and institute between described draining passageway and described first storage pond State and be provided with the second flow structure between the second storage pond, and cross water after being connected between described first storage pond and described second storage pond and lead to Road, described rear aquaporin of crossing is provided with one way stop peturn valve, is provided with submersible sewage pump, the water outlet of described submersible sewage pump in described first storage pond End is connected with described draining passageway.
Early-stage rainwater is directly discharged into sewage treatment plant by draining passageway and is processed by the present invention, it is to avoid initial stage rain The harm to natural water for the water;And pass through the first storage pond, the second storage pond, the first flow structure and the second flow structure appropriate Kind cooperation, regulates and controls to mid-term rainwater;The timely flood discharge of weir gate is controlled by flood discharge simultaneously, realize flood peak regulation and control, and then prevent Cities and towns waterloggings;After rainfall terminates, when water level decreasing in draining passageway is to setting value, the submersible sewage pump in the first storage pond is opened Open, the rainwater of storage in the first storage pond and the second storage pond is extracted in draining passageway and is discharged;The present invention is realizing just Phase rainwater can regulate and control to mid-term rainwater and flood peak, in time according to the difference of rainfall, the row to rainwater while separation Put row into control in order and regulate and store, be effectively prevented the pollution of the direct discharge of early-stage rainwater and the waterlogging in cities and towns, and structure letter Single, low cost, can Automatic Control, need not manually operate, regulate and store safe and reliable.
Further, described flood discharge controls the water level design height of weir gate to be more than the water level design of described first flow structure Highly, the water level design height of described first flow structure is more than the water level design height of described second flow structure.
Further, also include control unit, in described draining passageway, be provided with the first liquid level sensor, described first regulates and stores It is provided with the second liquid level sensor, the signal output part of described first liquid level sensor and described second liquid level sensor passes through in pond Described control unit is connected with the signal input part of described submersible sewage pump respectively.After rainfall terminates, when under the water level in draining passageway When dropping to setting value, the first liquid level sensor sends signal, thus the submersible sewage pump in the first storage pond is opened, by the first storage pond And second the rainwater of storage in storage pond be extracted in draining passageway and discharged;When in the first storage pond water level decreasing to setting value When, the second liquid level sensor sends signal, thus the submersible sewage pump in the first storage pond is closed.
Further, it is respectively equipped with flusher in described first storage pond and described second storage pond, described first tune It is provided with the first immersible pump in reservoir, in described second storage pond, be provided with the second immersible pump and the 3rd liquid level sensor;Described first The signal input part of immersible pump is connected with the signal output part of described second liquid level sensor by described control unit, and described The signal input part of two immersible pumps is connected with the signal output part of described 3rd liquid level sensor by described control unit.When When in one storage pond and the second storage pond, water level is reduced to setting value, the second liquid level sensor and the 3rd liquid level sensor send letter Number, thus the first immersible pump and the second immersible pump are opened, respectively to water filling in waterpower tipping bucket, storage pond bottom is carried out timely Rinse, the sewage of flushing is extracted out by submersible sewage pump, is discharged into sewage treatment plant through draining passageway and is processed.
Further, described draining passageway includes left bank hydroecium on front side of described first storage pond and is located at described the Right drip chamber on front side of two storage ponds, is connected with front aquaporin excessively, described front water excessively between described left bank hydroecium and described right drip chamber Passage is provided with permanent flow valve;Described flood discharge controls weir gate to be arranged in described left bank hydroecium.More due to containing in early-stage rainwater There is the particle of pollutant, and the rainfall of early-stage rainwater is not very big, during by draining passageway, directly discharges through permanent flow valve Processed to sewage treatment plant.
Further, described flood discharge controls weir gate to control weir gate for floating box type upstream.
Further, described first flow structure and described second flow structure are respectively overflow wall.Further, described Flusher is waterpower tipping bucket or flap type rinses door.
Further, described front aquaporin excessively is arranged on the bottom of described left bank hydroecium and the division wall of described right drip chamber End.
Further, described aquaporin excessively afterwards is arranged on the division wall of described first storage pond and described second storage pond Bottom.
