Sewage drainage device
The invention discloses a sewage drainage device. A support is installed above a sewage pit, a motor is installed in the middle of the upper surface of the support and is connected to a subsurface centrifugal pump in the sewage pit, the subsurface centrifugal pump penetrates the support to connect to a butterfly valve and a check valve through a pipeline, and a pressure gauge switch and a pressure gauge are installed on the pipeline between the butterfly valve and the check valve; a terminal case is installed on one side of the upper surface of the support, the other side is provided with a magnetic float level gauge, and the bottom of the magnetic float level gauge penetrates the support to locate into the sewage pit. The device has fine contamination resistance, large stroke and flow and wide application range; the magnetic float level gauge can be used for observing the sewage level in real time, automatic pumping stop is implemented through electrical control, and automatic control is implemented; the check valve is adopted, so that oil backflow due to the gravity can be prevented; the electrical control and manual control are adopted, and the on-site requirements are met well.
