a storm sewage drainage pipe network comprising: the device comprises a controller, a vertical water pipe, a plurality of floor sewage pipes, a water collecting tank, a cover plate, a sewage turbidimeter, a water baffle plate, a rainwater drain pipe, a sewage drain pipe and a rainwater and sewage drain switching device, wherein the upper end of the controller is provided with a roof rainwater inlet; the measuring sensor of the sewage turbidimeter is positioned on the left side of the vertical water pipe: the sewage turbidimeter is a sewage treatment online turbidimeter; the sewage turbidimeter is electrically connected with the controller.

Preferably, the rainwater drainage switching device includes: the device comprises two sliding rails which are respectively arranged on the upper side and the lower side of a rainwater drainage pipe and a sewage drainage pipe, a plugging plate, an electric push rod and a connecting rod, wherein two ends of the plugging plate are in one-to-one corresponding sliding connection with sliding grooves formed in the two sliding rails; the plugging plate plugs one end of the rainwater drainage pipe or one end of the sewage drainage pipe; the electric push rod is electrically connected with the controller.

Preferably, the rainwater and sewage drainage pipe network further comprises a protective cover detachably connected with the upper end of the cover plate; the controller and the sewage turbidimeter are positioned in the protective cover and are respectively in threaded connection with the cover plate.

Preferably, the upper end of the water baffle is provided with a water baffle strip positioned on the left side of the vertical water pipe and the measuring sensor of the sewage turbidimeter.

Preferably, one end of the rainwater drainage pipe is provided with a filter screen.

Compared with the prior art, the utility model has the beneficial effects that: when the rain sewage drainage pipe network does not rain, sewage of each floor flows into the water collecting tank from the floor sewage pipe through the vertical water pipe and is discharged from the sewage drainage pipe to be sent to a sewage treatment plant for treatment; when raining, rainwater enters from a roof rainwater inlet, is converged with sewage flowing in from a floor sewage pipe and then flows into a water collecting pool through a vertical water pipe, and a sewage turbidity meter measures the turbidity of the rainwater and the sewage flowing through the upper end of the water baffle; when heavy rain falls, the sewage turbidity meter measures that the turbidity of the rain sewage is reduced to a set turbidity value, the electric push rod is started, the push-pull rod of the electric push rod drives the plugging plate to move through the connecting rod to plug the sewage drain pipe, the rain sewage with lower turbidity automatically flows into the municipal drainage pipe network, and the sewage treatment capacity of a sewage treatment plant is reduced. The protection casing of being connected can be dismantled with apron upper end, does benefit to and prevents that controller, sewage turbidimeter are impaired. The upper end of the water baffle is provided with a water bar positioned on the left side of the vertical water pipe and the measuring sensor of the sewage turbidimeter, so that the thickness of rainwater and sewage flowing through the upper end of the water baffle is increased, and the turbidity measuring precision is improved. One end of the rainwater drainage pipe is provided with a filter screen, which is beneficial to preventing sundries from entering the rainwater drainage pipe.
