Removal effect.
Background technology
In sponge urban construction, source emission reduction is produced in rainwater and is converged mainly before rainfall contacts underlying surface to inlet for stom water
The source of stream, adaptation to local conditions take appropriate measures, change rainwater arrange soon, in line traditional method, using rainwater-collecting, purification and
It utilizes, to reduce, slow down the formation of rainfall runoff and collect discharge, mitigates the pressure of urban drainage pipe network, control initial rainwater
Pollution；Since site condition limits in the sponge urban renewal of old residential community, end rain flood is regulated and stored since its scale of construction is big and water outlet
Piping laying depth problem can not on a large scale use in old residential community sponge urban renewal, and source Mitigation options are due to taking up an area
Area is few, construction is flexible, transformation is convenient, and operability is high, is increasingly becoming the main technological means in old residential community sponge city.
Utility model content
The purpose of this utility model is to provide a kind of automatic ration sponge city source drainage equipment, for sponge city source
Head decentralised control, automatic, the quantitative emptying of water storage facility, the contaminant removal capacity for improving sponge facility.
To achieve these goals, the technical solution of the utility model is：A kind of automatic ration sponge city source draining
Equipment, including source water tank, the source water storage upper box part sets water inlet, and bottom sets discharge outlet, it is characterised in that stores up in source
Automatic drain valve is equipped in water tank, the automatic drain valve includes a convex arc-shaped housing, the arc-shaped housing bottom
Rubber membrane equipped with a sealing is fixed with briquetting on the rubber membrane, and the drain valve is arranged on above discharge outlet, and causes institute
It states rubber membrane to be covered in discharge outlet, the side of the arc-shaped housing is provided with the first aperture, and opposite side is provided with second orifice, institute
The diameter for stating second orifice is more than the diameter of the first aperture, and the second orifice is connected by a bend pipe with discharge outlet.
Further, the briquetting is round small iron block, and diameter is equal with discharge outlet.
Further, the bend pipe includes the first straight tube, the second straight tube being arranged in parallel with first straight tube, and described the
The lower end of one straight tube is connect with second orifice, and the upper end of the first straight tube is connect with the upper end of the second straight tube by elbow, and described
The lower end of two straight tubes is then connect by a transverse tube with discharge outlet.
The utility model has the advantage of the automatic water traps can realize Auto-drainage, by the water for controlling water inlet
Flow can realize that quantitative draining can realize water discharge time, source water storage facility be enable to have the sufficient residence time, so as to carry
The contaminant removal capacity of high sponge facility.The automatic ration sponge city source drainage equipment, floor space is few, does not change original
There is greening design, do not influence original soil composition and plant recovery, part construction, complete set are buried, and transformation is convenient, it is simple to implement
Just, operability is high, based on gravity flow, does not increase original draining absolute altitude, non-power consumption, without operating cost.
Description of the drawings
Fig. 1 is automatic ration sponge city source drainage equipment schematic diagram.
Fig. 2 is automatic drain valve schematic diagram.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
A kind of automatic ration sponge city source drainage equipment of the utility model, including source water tank 1, source storage
Water tank 1 is equipped with water inlet 2, and discharge outlet 3, for 1 inside of source water tank equipped with drain valve, the drain valve includes a spherical crown shape
Copper product, the copper product of the spherical crown shape are equipped with convex arc-shaped housing 4, and there are one the rubber membranes sealed for arc-shaped housing bottom
5, arc-shaped housing side is provided with pore A, and opposite side is provided with more larger hole B, and a bend pipe one end is inserted into the B of hole, another
End is connected with discharge outlet, and the rubber membrane 5 is flexible, is fixed on the small iron block 6 of one piece of circle（Diameter is equal with discharge outlet）
To push down discharge outlet.When water is from water inlet 2 into source water tank 1, discharge outlet is pushed down by rubber membrane 5, it is impossible to draining.With
Water level rise, water is flowed through by hole A in spherical crown, and flows into bend pipe 7 from hole B, due to rubber membrane about 5 hydraulic pressure it is equal, still press
Firmly discharge outlet.When water level continuously rises to be more than bend pipe peak, water will pass through bend pipe and flow into discharge outlet discharge, due to hole B
More than hole A, water is by the way that, again by larger resistance, pressure also has loss, therefore discharge reduction in spherical crown, top will appear very during A holes
Sky, at this time rubber membrane top pressure reduce sharply, lower part pressure be equal to atmospheric pressure add water generate pressure, much larger than top press
By force, dash forward on rubber membrane, discharge outlet is opened, and the water in water tank starts to discharge, in water tank during water level decreasing, water in spherical crown due to
Siphonage still can be discharged by bend pipe, maintained vacuum presence, rubber membrane is not caused to move down, while control the water of water inlet
Flow can control drainage period, realize automatic, quantitative draining.
The utility model and sponge city end rain flood facility of regulating and storing are compared from effluent quality and applicable elements below.
（1）Effluent quality
Rain flood facility of regulating and storing in end is only used for the regulatory function of avoiding the peak hour of rainwater, and the rainwater residence time is unable to control, so going out
Water water quality is unstable, is unable to control pollutants removal rate, and the requirement of sponge city " net " is not achieved；Automatic ration sponge city source
The control of head drainage equipment water discharging time is in the case of quantitative emptying for 24 hours, and pollutants removal rate can reach more than 70%, water outlet
For time control in the case where 48 h are quantitatively emptied, pollutants removal rate can reach more than 85%.
（2）Applicable elements
Rain flood facility of regulating and storing in end is useful in cell and has the large stretch of greening of concentration and the municipal catch-basin absolute altitude deep enough（It needs
Sinking rain flood is regulated and stored the height of facility on original absolute altitude, and finished product module is generally 600-1200mm）If municipal catch-basin absolute altitude
Embedded requirement can not be met, need to increase lifting means, it is contemplated that later stage estate management and operating cost considers, generally cannot be by
Resident receives；Automatic ration sponge city source drainage equipment is suitable for the water storage facility of scattering device, and floor space is few, does not change
Become original greening design, do not influence original soil composition and plant recovery, part construction, complete set are buried, and transformation is convenient, real
Apply simplicity, operability is high, based on gravity flow, does not increase original draining absolute altitude, non-power consumption, without operating cost.
In conclusion the utility model has good use value and promotional value.
