AI Technical Summary

Technical Problem

The existing sponge urban rainwater utilization device has a small collection area, which leads to waste of rainwater. The lack of anti-blocking devices in the filter pipes, resulting in poor blockage and filtration effects, unable to meet the third-class water indicators on the surface, and cannot be directly used for crop irrigation and urban greening.

Method used

A device including a cylinder, a collection funnel, a purification barrel, a purification pipe, a filter pipe and a lifting plug was designed to control the entry of rainwater through floating blocks, and use multiple filter layers (activated carbon, gravel, sand and gravel) and screens to carry out the Filter and automatically add alum through stepper motor and rotary blades. Combined with a transparent shell and distance sensor to monitor the filtration effect, ensuring efficient collection and filtration of rainwater.

Benefits of technology

Large-area collection and multi-level filtration of rainwater are achieved, minimizing waste, automatically adjusting rainfall, improving filtration effect, ensuring that the collected rainwater meets the usable standards, and is suitable for crop irrigation and urban greening.

Abstract

The utility model discloses a rainwater utilization device for a sponge city, which relates to the technical field of sponge cities and comprises a barrel body, a collecting funnel is arranged at an opening at the top of the barrel body, a purifying barrel is arranged in the barrel body, a liquid inlet is arranged at the top of the purifying barrel and communicated with a purifying pipeline, and an outlet of the purifying pipeline penetrates through the purifying barrel and the barrel body and is communicated with a reservoir. A filter pipe is arranged on the purification pipeline, and a plurality of filter layers are arranged in the filter pipe; a lifting plug is arranged at the liquid inlet, and a floating block is arranged at the top of the lifting plug and used for controlling movement of the lifting plug. By arranging the collecting funnel and the purifying pipeline, rainwater generated by rainfall can be collected and stored in a large area, by arranging the lifting plug, opening and closing collection can be automatically conducted when rainfall exists or not, more convenience is achieved, and by arranging the filtering pipe, the collected rainwater can be filtered in a multi-layer mode, and the usable standard is achieved.
