Description

Pull-up type weir gate for intercepting well

Technical Field

The utility model relates to the technical field of hydraulic equipment, in particular to a pull-up type weir gate for a intercepting well.

Background

In the current urban construction, due to the fact that the earlier stage planning of an urban underground pipe network is incomplete in reaching and construction, and partial residents have poor awareness of diversion of rain and sewage, the phenomenon that rain and sewage pipelines in many urban communities are connected in a mixed mode and arranged in a staggered mode commonly exists, and sewage is poured at will along street shops and booths at will, so that a large amount of sewage enters the rain and sewage pipelines in a wrong mode, and then enters a river channel to pollute the water quality of the river channel.

The sewage intercepting well can effectively separate and discharge sewage in a rainwater pipeline into the sewage pipeline in a common mode, the intercepting well is provided with a weir gate on the front side of the same flow pipe, the rainwater pipeline and the sewage are separated by the weir gate in sunny days, and water flow can overflow the weir gate in rainy days, so that the sewage intercepting well can flexibly cope with different rainy and water discharge amounts, and at present, a plurality of weir gates are made to be adjustable, wherein the mode of vertical lifting adjustment is widely applied. In the regulation mode of vertical lifting, two sides of a weir plate (or door) are clamped in a vertical groove, and are driven to lift by a motor, a screw rod (the screw rod is easy to rust in a sewage environment) or a hydraulic cylinder, because more solid impurities exist in sewage, the weir plate cannot be just matched with the vertical groove, otherwise, after the solid impurities are clamped in, the condition of clamping easily occurs, a gap with a certain size exists between the weir plate and the vertical groove, then the weir plate can shake unstably when lifting, so that collision damage is caused, and the driven hydraulic cylinder is applied with torsion along with shaking, so that damage can occur easily.
