Municipal rainwater colleting system

Abstract

The invention relates to a municipal rainwater collecting system which comprises a collecting barrel, a filtering net, a water pump and a spraying pipe. The collecting barrel is provided with a waterinlet pipe and a water outlet pipe, the filtering net is arranged in the collecting barrel, the water pump is arranged on the water outlet pipe, and the spraying pipe communicates with the water pump.A partition plate is arranged in the collecting barrel, and the interior of the collecting barrel is divided into a separation area and a storage area through the partition plate. A stirring shaft coaxial with the collecting barrel is arranged in the separation area, and a motor used for driving the stirring shaft to rotate is arranged on the collecting barrel. Multiple first through holes communicating with the upper surface and the lower surface of the partition plate are formed in the position of a middle ring of the partition plate, and an opening and closing mechanism used for opening and closing the multiple first through holes at the same time is arranged on the partition plate. When rainwater rotates at a high speed, the opening and closing mechanism opens the first through holes,and when rainwater does not rotate at a high speed, the opening and closing mechanism closes the first through holes. By means of the scheme, the probability that the filtering net is blocked is lowered, subsequent normal spraying of rainwater is ensured, and the frequency of cleaning the filtering net of workers is further lowered.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a municipal rainwater collection system. Background technique [0002] With the popularization of municipal construction in our country, green plants, such as flowers and trees, are often planted on both sides of the traffic road. The planted green plants need to be watered regularly to ensure the healthy growth of the green plants. This process requires a lot of water consumption. Resources, in order to change this phenomenon, some municipal rainwater collection and utilization devices have appeared on the market at present, to use rainwater to water green plants. [0003] The traditional municipal rainwater collection and utilization device includes a collection bucket provided with an inlet pipe and an outlet pipe, a filter screen arranged inside the collection bucket, a water pump arranged on the water outlet pipe, and connected to the water pump for spraying rain...

AI Technical Summary

Problems solved by technology

[0004] Although the traditional municipal rainwater collection and utilization device is simple in structure and simple in use principle, when the pump is started, sand, stones, fallen leaves and other debris in the rainwater will easily block the filter screen, which not only affects the normal spraying of rainwater , It also greatly increases the frequency of staff cleaning the filter, which brings inconvenience to the work of staff
