Drainage pipe scour and interception device

Abstract

The invention provides a drainage pipe scour and interception device. The drainage pipe scour and interception device is controlled based on a floating ball, wherein a door body is configured to rotate at the closing position where a drainage pipe is closed to intercept drainage and at the opening position where the drainage pipe is opened to drain flood and scour; an elastic part holding the doorbody in the closing position allows first water level pressure in the drainage pipe to open the door body; a first floating body and a first control part are arranged in an associated mode through alinkage mechanism, when the water level does not reach a first water level, the first control part is kept in the state of buckle with the door body, and when water in the drainage pipe reaches the first water level, the first floating body drives the first control part to trip with the door body as the water level rises to make the first control part to rotate and release flood water; and a second floating body and a second control part are arranged in an associated mode through the linkage mechanism, the second floating body drives the second control part to move to the position where the second control part can buckle with the door body when flood discharge and scour are conducted, after the flood discharge and scour are finished, the second floating body drops with the water level anddrives the second control part to move to trip with the door body.

Description

technical field [0001] The invention relates to a drainage intercepting device for drainage pipes in municipal engineering. After intercepting the drainage to a certain water level, the intercepting device is opened for flood discharge and scouring. Background technique [0002] At present, the technologies for cleaning the sediment in the drainage pipeline mainly include rocker dredging, high-pressure water jet method, HydroGuard Mini miniature storage flushing door, HydroSelf door type automatic flushing system, HydroFlush automatic siphon flushing device, and drainage pipe automatic flip weir plate interception based on spring compression Flush device. Traditional dredging methods such as rocker dredging have low automation and low efficiency. New dredging methods such as "suction mud king" and high-pressure water jetting have high energy consumption, water consumption, and high maintenance costs. These dredging methods are all Diverts sediment out of pipes, affecting th...
