Description

Technical Field

[0001] This utility model relates to the field of building components technology, and in particular to a structure for collecting and reusing rainwater for energy conservation in buildings. Background Technology

[0002] In the field of building energy conservation, rainwater harvesting and reuse is of great significance for saving water resources and reducing building operating costs. However, existing building rainwater harvesting systems have many drawbacks. Traditional collection devices often lack effective means of filtering impurities in the initial rainwater runoff, allowing larger particles such as leaves and gravel to easily enter the collection system, clogging pipes and affecting the subsequent purification and utilization of rainwater.

[0003] Common rainwater harvesting structures have relatively simple drainage designs, making it difficult to flexibly adjust drainage paths according to different scenarios and meet diverse water demand. In terms of cleaning and maintenance, previous designs did not fully consider convenience, making the work of cleaning impurities and maintaining equipment cumbersome and complicated, consuming a lot of manpower and resources. These problems seriously restrict the efficient operation and widespread promotion of building rainwater harvesting and secondary utilization systems. Utility Model Content
