Utility model content
The technical problems to be solved in the utility model is that existing catch basin can not carry out automatic-diversion closure according to amount of rainfall, and a kind of automatic control pollution cutting device for automatic-control intercepting well is provided for this reason.
The technical solution of the utility model is: for the automatic control pollution cutting device of automatic-control intercepting well, it comprises flashboard and baffle plate, described flashboard bottom is provided with the mouth of pipe being communicated with wastewater interception pipe, baffle plate is connected with the ball float being hinged on flashboard by the gear train assembly being fixed on flashboard, drives baffle plate to cover or expose the mouth of pipe in the time that ball float fluctuates.
Gear train assembly described in such scheme is positioned at the side that flashboard departs from axis.
The improvement of such scheme is on described flashboard, to be also connected with the seal diaphragm that wraps gear train assembly.
Ball float described in such scheme is hollow circular cylinder, and end face and the hollow circular cylinder body of described hollow circular cylinder removably connect.
Thereby the beneficial effects of the utility model are ball floats to be driven baffle plate to move up and down by gear train assembly to play according to the effect of discharge automatic-diversion closure, convenient and swift, seal diaphragm can avoid impurity to enter gear train assembly, blocking gear makes it can not transmission, ball float is designed to hollow circular cylinder, and make an one end face detachable, convenient control with this speed and amplitude that baffle plate moves up and down to packing charges in hollow circular cylinder.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, the utility model comprises flashboard 1 and baffle plate 2, described flashboard bottom is provided with the mouth of pipe 3 being communicated with wastewater interception pipe, baffle plate is connected with the ball float 5 being hinged on flashboard by the gear train assembly 4 being fixed on flashboard, drives baffle plate to cover or expose the mouth of pipe in the time that ball float fluctuates.
When installation, flashboard is vertically fixed in wastewater interception pipe, the mouth of pipe is connected with wastewater interception pipe, at ordinary times ball float under, baffle plate is above the mouth of pipe, in the time that in wastewater interception pipe, rainwater flow becomes large, ball float floats the transmission of driven gear transmission system baffle plate is fallen, and plays the object of automatic-diversion closure.
Gear train assembly is preferably positioned at the side that flashboard departs from axis, and can be driven the amplitude moving up and down larger for baffle plate like this.
On flashboard, be also connected with the seal diaphragm 6 that wraps gear train assembly, it can make gear train assembly by isolation, avoids dust impurity to enter the locked system of gear train assembly.
Ball float can be hollow circular cylinder, hollow in it, an end face of hollow circular cylinder is designed to dismountable, such as being threaded, clamping, hinged etc., filling fine sand or tap water in hollow circular cylinder, increase the deadweight of ball float if desired, when ball float floats like this, can allow the baffle plate slowly closing mouth of pipe, when ball float falls, can open rapidly the mouth of pipe.
Automatic control pollution cutting device is installed in automatic-control intercepting well, when fine day, it in confluence of rainwater and sewage pipe, is all sanitary sewage, flow is less, in catchpit, water level is lower, ball float is in lower position, and baffle plate is in opening, and sanitary sewage enters and directly enters into sewage backbone network by the mouth of pipe 3 after catchpit and finally enter Wastewater Treatment Plant; When rainy day, flow in confluence of rainwater and sewage pipe increases gradually, now the water level in well body also raises gradually, ball float in the pollution cutting device of automatic control simultaneously also can float along with the rising of water level, thereby drive automatic control pollution cutting device to close, now rainwater is no longer by the mouth of pipe but directly discharge by storm-water drainage mouth; After rain stops, water level declines, and now ball float will fall due to deadweight, thereby automatic control pollution cutting device is opened.Thereby while having realized fine day, sewage is dammed, when the rainy day, avoid rainwater to enter into sewage network.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
