Push-up hydraulic weir gate at overflow port of intercepting and diverting well

Technical Field

The utility model relates to a control gate of a municipal drainage pipe network, in particular to an upward pushing type hydraulic weir gate at an overflow port of a intercepting and diverting well.

Background

In the prior art, when urban rainfall exceeds the water delivery capacity of an urban drainage pipeline, flood disasters can occur in cities, and in order to prevent the occurrence of waterlogging, a rain flood regulating reservoir is arranged to store the rain flood exceeding the water delivery capacity of the drainage pipeline into the rain flood regulating reservoir, and after rainfall is finished, the rain flood in the rain flood regulating reservoir is discharged through a submersible sewage pump, so that urban waterlogging is prevented.

However, if the rain flood regulation tank is full, and the rainfall is still continuous, the excessive water body is discharged to the surrounding natural water body through the overflow port, on one hand, the regulation tank has no regulation volume, the urban upstream waterlogging can be caused by the fact that the regulation tank is not discharged, on the other hand, the later-stage rainwater is relatively clean, and the discharged part can have relatively less damage to the natural water body.

For a closure diversion well in a municipal drainage system, when the water inflow exceeds the closure and diversion set quantity excessively, the redundant water body also needs to be discharged through an overflow port, and the water level of the overflow water outlet needs to be adjustable and controllable.

In a rainy region, the river water level at the downstream of the overflow port is often higher, so that overflow is possibly unsmooth, or the river water body flows back into the intercepting and diverting well, and the condition also needs to control the water body to flow back through the overflow port weir gate.

The monitoring and automatic control of the overflow port cannot be realized by the traditional cement wall overflow port.
