Description

Technical Field

[0001] The utility model relates to the technical field of water level control, in particular to a water level and water volume regulating controller. Background Art

[0002] In order to avoid water pollution and improve the operating efficiency and effect of sewage treatment plants, the newly built urban drainage systems are all rainwater and sewage diversion systems. Since the initial rainwater is more polluted and the later rainwater is less polluted, the drainage system of the rainwater and sewage diversion system should separate and divert the heavily polluted initial rainwater and the lightly polluted later rainwater through the control weir gate in the drainage pipe network system, that is, the heavily polluted rainwater is discharged into the sewage pipe network and connected to the urban sewage treatment plant for treatment. The lightly polluted rainwater in the later period is directly discharged into the receiving water body through the rainwater pipe network system. This patent solves the problem of rainwater and sewage diversion and initial rain abandonment.

[0003] The existing bottom-opening weir gates are generally prone to being entangled and blocked by garbage in the well when moving up and down, resulting in the weir plate gate being unable to be properly stuck, driver failure, etc., which leads to the weir gate being unable to operate normally; at the same time, since traditional hydraulic drive devices are mostly placed underwater, once they are stuck, the weir gate must be lifted for maintenance, which is a large amount of work and takes a long time to recover. In addition, multiple liftings can easily cause the weir gate to deform, which is not conducive to maintaining the best condition of the weir gate. This patent uses an external hydraulic motor driver to solve the problem of inconvenient maintenance of traditional hydraulic drive devices, and the weir gate is stable in lifting and lowering.
