Description

Technical Field

[0001] The utility model relates to the field of rainwater and flood resource utilization, in particular to multifunctional rainwater and flood resource utilization equipment. Background Art

[0002] The utilization of rainwater and flood resources refers to the conversion of rainwater and floods that might otherwise be lost or cause disasters into water resources that can be used for human life and production through a series of engineering and non-engineering measures. The purpose is to improve the efficiency of water resource utilization, ensure flood control safety and promote ecological environment improvement.

[0003] A Chinese patent application with the existing publication number CN214781066U discloses a road rainwater resource utilization device, comprising a sludge filter tank and a filter chamber. The sludge filter tank is provided with a sludge valve at the lower end, and a rotary handle is provided at the right end of the sludge valve. A rainwater delivery pipe is provided on the lower side of the right end of the sludge filter tank, and a honeycomb filter is provided at the top of the right end of the rainwater delivery pipe. The filter chamber is mounted on the outer end of the honeycomb filter, and a slider is provided at the lower end of the honeycomb filter. The lower end of the slider is provided with a slide, and the lower end of the slide is provided with a sediment filter layer. The road rainwater resource utilization device is provided with a sludge filter tank, which is arranged perpendicular to the sludge valve. Rainwater first flows into the sludge filter tank. Because rainwater contains many large particles, which not only clog the filtering parts but also damage the overall purification system, the sludge is first filtered out. Then, a rotary handle is provided at the bottom of the sludge filter tank so that the rotary handle can be opened.

When the water quality is not filtered cleanly, fine parts such as water valves may be clogged, affecting the use function and the operation of the entire system. There is a lack of corresponding structure here, which needs to be improved and optimized. Utility Model Content
