Description
Technical field
The utility model relates to municipal drainage technical fields, and in particular to a kind of city rain dirt pipe drainage system.
Background technique
The rain-water drainage pipe network and sewage drainage pipe network in city are all independently arranged at present, and rainwater can be straight in Storm Sewer Network
Run in and be put into natural water source, the sanitary sewage in sewage drainage pipe network is discharged into Natural Water after need to being discharged into sewage treatment plant's processing
In source, when encountering rainwater weather, the discharge pressure of rain-water drainage pipe network increases, and in China city, is frequently encountered rainwater
It discharges too late, causes the scene of " water overflows Kingsoft ", make troubles to traffic and safety.Due to rain-water drainage in sewerage system
Pipe quantity is more, while the regional location being distributed is different, thus when more communicating pipes of needs and valve carry out and sewage drainage pipe
Be interconnected when, need repeatedly it is artificial each place carry out open and the later period closing, when leading to the operation of the program
Between long, high labor cost.
Utility model content
The technical problems to be solved in the utility model is to solve above-mentioned the deficiencies in the prior art, is provided a kind of rationally using dirty
The city rain dirt pipe drainage system of waterpipe reduction catch-basin drainage pressure.
In order to solve above-mentioned the deficiencies in the prior art, the technical solution adopted in the utility model are as follows: a kind of city rain dirt pipe
Road drainage system, including collecting the catch-basin of rainwater and for the bilge well of blowdown, overflow weir is provided in the middle part of catch-basin will
Catch-basin is divided into storage area and buffer area, setting buffers rain water outlet, and rainwater discharge outlet connects bilge well by pipeline,
The valve plate that buffer area is provided with U-shaped framework at rainwater discharge outlet and is slidably matched with U-shaped framework, the U-shaped framework inside
Sliding slot is set, sealing strip is provided on the inside of sliding slot, sealing strip is made of elastic material；Sealing strip side is arranged in U-shaped framework
On side wall, the other side is contacted with the backboard squeezed tight of valve plate；Valve plate top plate connects a floating ball, and floating ball drives valve plate to move up.
Further, it is provided with fixed plate and pressing plate on U-shaped framework side wall, by pressing plate, sealing strip and is consolidated with bolt
Fixed board three fixes, thus fixing seal item.
Further, it is additionally provided with refluxing opening in overflow weir bottom, the side also flap valve that refluxing opening is located at storage area prevents
Storage area rainwater pours into buffer area.
Further, the storage area bottom is provided with slope for settled sludge.
From above-mentioned technical proposal it can be seen that the utility model has the advantage that by the way that buffer area is arranged, when heavy rain is led
When causing excessive rainfall and filling up storage area, the rainwater of excess is able to enter in buffer area, plays the rainwater for increasing catch-basin
The effect of capacity.When filling up buffer area, floating ball rises from driving valve plate to rise, and Sewage outlet and bilge well are interconnected,
The rainwater of excess can be discharged into bilge well, rainwater is discharged by bilge well, avoids the generation of disaster.When rainwater quilt
Water level decreasing after discharge to a certain degree, at this time since the gravity of valve plate itself can automatically reset.On the other hand when in bilge well
Sewage excess when, due to the unidirectional barrier action of valve plate, sewage generate hydraulic pressure baffler will not be opened, so that it is guaranteed that
Bilge well will not enter catch-basin, avoid sewage by rainwater pollution；Since sealing strip has elasticity, formed between meeting and valve plate
It squeezes, forms good sealing, when opening and closing valve plate, sealing strip can be with valve plate friction, and the thickness of sealing strip can be reduced, due to close
Strip of paper used for sealing has elasticity, can still contact with valve plate squeezed tight, keep good sealing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model
Fig. 2 is the structural schematic diagram of valve board assembly in the utility model.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the city rain dirt pipe drainage system of the utility model, the catch-basin including collecting rainwater
With the bilge well 11 for blowdown, it is provided with overflow weir 2 in the middle part of catch-basin by catch-basin and is divided into storage area 1 and buffer area 7, delays
It rushes area 7 and is provided with rainwater discharge outlet 10.It is additionally provided with refluxing opening 5 in 2 bottom of overflow weir, refluxing opening 5 is located at the side of storage area
Also flap valve 6 prevents storage area rainwater from pouring into buffer area.The storage area bottom is provided with slope 4 for settled sludge.
Rainwater discharge outlet 10 connects bilge well 11 by pipeline 9, and buffer area 7 is provided with U-shaped framework 8 at rainwater discharge outlet
And the valve plate 13 being slidably matched with U-shaped framework, sliding slot is set on the inside of the U-shaped framework 8, sealing strip is provided on the inside of sliding slot
16, sealing strip 16 is made of elastic material；16 side of sealing strip is arranged on U-shaped framework side wall 17, the back of the other side and valve plate
The contact of 19 squeezed tight of plate；Valve plate top plate connects a floating ball 3, and floating ball drives valve plate to move up.
By the way that buffer area is arranged, when heavy rain leads to excessive rainfall and fills up storage area, the rainwater of excess is able to enter
Into buffer area, play the role of increasing the rainwater capacity for arriving catch-basin.When filling up buffer area, floating ball rises from drive valve plate
Rise, Sewage outlet and bilge well are interconnected, the rainwater of excess can be discharged into bilge well, by bilge well by rainwater into
Row discharge, avoids the generation of disaster.Water level decreasing after rainwater is discharged to a certain degree, at this time due to the gravitation energy of valve plate itself
Enough automatically reset.On the other hand when the sewage excess in bilge well, due to the unidirectional barrier action of valve plate, the water of sewage generation
Pressure will not open baffler, so that it is guaranteed that bilge well will not enter catch-basin, avoid sewage by rainwater pollution；Due to close
Strip of paper used for sealing has elasticity, is formed and is squeezed between meeting and valve plate, forms good sealing, when opening and closing valve plate, sealing strip meeting and valve plate
Friction, the thickness of sealing strip can be reduced, and had elasticity due to sealing strip, can still be contacted with valve plate squeezed tight, keep good
Sealing.
In addition, be provided with fixed plate 18 and pressing plate 15 on U-shaped framework side wall 8, with bolt by pressing plate 15, sealing strip 16 with
And 17 three of fixed plate fixes, thus fixing seal item.
