Abstract

The utility model provides a rain-sewage diversion device, and aims to provide a rain-sewage diversion device, which is simple in structure, low in price and free of power consumption and effectively diverts rain and sewage so as to relieve pressure of sewage treatment. The rain-sewage diversion device comprises a rain-sewage confluence pipe (1), a catch basin (2), an intercepting pipe (3) and a rain draining pipe (6), wherein two parallel fixed shafts (8) are disposed in the catch basin (2), one fixed shaft (8) is parallel to a center axis of the intercepting pipe and disposed right above the intercepting pipe (3), a gate (4) is disposed in an intercepting frame (9), the gate (4) and a float bowl (5) are connected with the two fixed shafts (8) respectively, and a lightweight flap valve (7) is installed at an outlet of the rain draining pipe (6).

Description

The dirty part flow arrangement of a kind of rain

Technical field

The utility model relates to the dirty part flow arrangement of a kind of rain.

Background technology

The employing interflow formula draining system of damming is that the present a kind of investment of China is less relatively, transform and build relatively easy preferable selection, and catchpit is used as water conservancy project structure a kind of commonly used and system's hinge in the interflow formula sewerage pipeline network that dams.But two hang-ups that traditional catchpit is faced are, one cuts dirty pipe to waterlogging caused by excessive rain season can not close automatically, rainwater is got into cut dirty pipe and then get into sewage disposal system, has strengthened the pressure of sewerage treatment; If physical features selects improper meeting the phenomenon that water pours in down a chimney to occur.

Summary of the invention

The purpose of the utility model is that a section dirty pipe that overcomes catchpit can not be closed automatically, and the phenomenon of flow backwards provides a kind of rain simple in structure, cheap, that need not power consumption dirty part flow arrangement.

The utility model adopts following technical proposals: the dirty part flow arrangement of a kind of rain comprises the dirty collecting fitting of rain, catchpit, cuts dirty pipe, storm-water drainage pipe, its difference be to be provided with in the catchpit two secured in parallel axles, one of them fixed axis laterally arrange with the central axis that cuts dirty pipe and be positioned at cut dirty pipe directly over; Gate is positioned at the frame that dams, and gate is connected through said two fixed axis respectively with floating drum; A light-duty flap valve is installed in the outlet of storm-water drainage pipe.

When liquid level in the catchpit was low, sewage got into catchpit by the dirty collecting fitting of rain, because the water surface is not high, keg float does not float, and gate is in opening at this moment, after sewage gets into catchpit, directly finally got into Wastewater Treatment Plant through cutting dirty pipe entering sewage backbone network; When liquid level was high in the catchpit, this moment, keg float will float along with the rising of water level, cut closing of dirty gate thereby drive; Rainwater no longer entered in the soil pipe but directly discharged through the storm-water drainage mouth this moment; Drawdown after rain stops, this moment, keg float will fall owing to deadweight, thereby made a section dirty gate opening; The light-duty flap valve of storm-water drainage pipe outlet is closed and has effectively been prevented to pour in down a chimney

Thereby realized the effect of the dirty shunting of rain.

Adopt technique scheme, the width of gate is more than or equal to the diameter that cuts dirty pipe; Gate is that hinge is connected with fixed axis, floating drum with fixed axis.

In sum; The beneficial effect of the utility model is: the buoyancy that has made full use of object; Flashboard is set in catchpit to be connected with keg float; Control the flow direction of sewage and rainwater, simple in structure, cheap, need not power consumption, effectively realized the dirty shunting of rain, alleviated the pressure of sewerage treatment; In the outlet of storm-water drainage pipe one light-duty flap valve is installed, has been prevented the problem of flow backwards effectively, alleviated the pressure of sewerage treatment greatly, realized the dirty shunting of rain well.

Description of drawings

Fig. 1 is the utility model schematic representation of apparatus;

Among the figure, the dirty collecting fitting of 1 rain; 2 catchpits; 3 sections dirty pipes; 4 gates; 5 floating drums; 6 storm-water drainage pipes; 7 light-duty flap valves; 8 fixed axis; 9 frames that dam

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

Under normal circumstances; Sewage gets into catchpit 2 by the dirty collecting fitting 1 of rain, because catchpit 2 waters surface are not high, keg float 5 does not float; This moment, gate 4 was in opening, finally got into Wastewater Treatment Plant so directly get into the sewage backbone network through a section dirty pipe 3 behind the sewage entering catchpit 2.

And when running into the rainy day, water levels can rise in the catchpit 2, and this moment, keg float 5 will float along with the rising of water level, close thereby drive gate 4, and rainwater no longer entered into and cut in the dirty pipe 3 but directly discharge through storm-water drainage pipe 6 this moment.In the catchpit 2 after the drawdown, this moment, keg float 5 will make gate 4 open owing to deadweight is fallen, and then had realized the effect of the dirty shunting of rain after rain stops.The light-duty flap valve 7 of storm-water drainage pipe 6 outlets is closed automatically, prevents that effectively rainwater from pouring in down a chimney.
