Sponge city large and small rainwater flow-dividing and discharging device

Abstract

The invention provides a sponge city large and small rainwater flow-dividing and discharging device. The device comprises a rainwater collecting thin pipe, a first connecting plate, a flow-dividing pipeline, a second connecting plate, a rainwater collecting thick pipe, a water inlet pipe, a filtering cover and a supporting frame, wherein the rainwater collecting thin pipe is fixedly arranged on one side of the rainwater collecting thick pipe; the supporting frame is installed at the bottom of the rainwater collecting thin pipe, the first connecting plate is connected to the upper portion of the rainwater collecting thin pipe, and the flow-dividing pipeline is connected to the side, away from the rainwater collecting thin pipe, of the first connecting plate; the flow-dividing pipeline is connected to the upper portion of the second connecting plate, and the rainwater collecting thick pipe is connected to the side, away from the flow-dividing pipeline, of the second connecting plate; andthe water inlet pipe is connected to the top of the flow-dividing pipeline, and the filtering cover is arranged at the top of the water inlet pipe. According to the discharging device, the water discharging effect can be achieved only through the rainwater collecting thin pipe in light rain, the rainwater collecting thin pipe runs in a full-load mode in heavy rain, at the moment, redundant rainwater can overflow into the rainwater collecting thick pipe through the flow-dividing pipeline, and the effect of discharging a large amount of rainwater is achieved.

Description

Technical field: [0001] The invention relates to the technical field of municipal installation engineering equipment, in particular to the technical field of urban rainwater drainage devices, in particular to a large and small rainwater diversion and drainage device for sponge cities. Background technique: [0002] At present, the existing drainage systems of large and medium-sized cities in my country generally have the problem of poor drainage. In case of heavy rain, it is easy to cause urban waterlogging, which requires temporary pumping and drainage, which affects the normal operation of the city and also causes huge economic losses. In response to the above problems, the concept of sponge city management came into being. Sponge city refers to a city that can absorb, store, infiltrate and purify water when it rains like a sponge, release and use the stored water when needed, realize the free migration of rainwater in the city, and adapt to environmental changes and respo...
