Drainage tube and collecting fitting have a gap between drainage tube and the plastic pipe on same axis, flexible in order to make valve opening, reduce the frictional force between valve and the plastic pipe, and the material of plastic pipe can be cast nylon with nylon or oil-containing.
Floatage control device is made up of slide bar, sliding sleeve, slide block, rocking bar, pull bar, lever, ball float and valve, the left end of slide bar is fixedlyed connected with spheroid, right-hand member and slide block are hinged, the centre is positioned at sliding sleeve, sliding sleeve is fixedlyed connected with the well body, rocking bar is a knee, union elbow place and well body are hinged, vertical end partly is positioned at slide block, the other end and pull bar are hinged, and the other end of pull bar and the middle and upper part of lever are hinged, and an end of lever is fixedlyed connected with ball float, the other end and well body are hinged, the middle and lower part mounted valve.
When drought stream or rainfall hour, the water surface is lower in the overflow well, ball float falls, and drives valve and falls, and makes valve closed gradually, at this moment, the gap location of valve between drainage tube and plastic pipe, in the valve closes process, the spillway discharge of bend pipe also reduces thereupon, with reach keep here the bigger sewage of pollutant or early stage rainwater, and the purpose of the less later stage rainwater of pollutant is fallen in overflow.
The water surface is lower in catchpit, ball float falls, the drive lever rotates counterclockwise, the lever pushing pull bar moves downward, pull bar promotes rocking bar and rotates counterclockwise, and rocking bar drives slide block and moves right, and slide block drives slide bar and moves right, slide bar drives spheroid and moves right, and the gap between spheroid and the Taper Pipe is strengthened.But because this moment, the water surface was lower, the pressure of the sewage of the mouth of pipe that dams is less, and flow velocity is less, and flow is certain.And when rainfall was big, the water surface raise gradually in the catchpit, and ball float lifts, and drove spheroid to left movement, and the gap between spheroid and the Taper Pipe reduces.But because this moment, the water surface was higher, the pressure of the sewage of the mouth of pipe that dams is bigger, and flow velocity is bigger, and flow is also certain.If the size of each member in the floatage control device is rationally determined, just can be made the distance of cone move left and right corresponding, thereby make the amount of damming of intercepting sewer constant with water surface elevation.
Because the lifting of the water surface drives the lifting of ball float, ball float lifting meeting drives the motion of spheroid and valve simultaneously, and the time of control amount of damming and overflow and size are so be referred to as to dam-overflow interlock control catchpit.
The utility model has the advantages that:
Solved under the constant situation of the processing of existing Wastewater Treatment Plant, storage capacity and catchpit, pipe network storage capacity, reduced the discharging of the higher early-stage rainwater of pollutant load, and allowed the lower later stage stormwater overflow of pollutant, realized the maximization that pollutant dams.
