Description

Technical Field

[0001] The utility model relates to the technical field related to rainwater collection and filtration on building roofs, and in particular to a rainwater collection and filtration device on the building roof. Background Art

[0002] The rainwater collection system on the roof of a building is an environmentally friendly and sustainable way of using water resources. By setting up water collection equipment on the roof of the building, rainwater is collected and stored for subsequent use. This system usually includes a roof drainage system, a sedimentator, a filter and a water storage device. The working process of the rainwater collection system is that when rainwater flows over the roof, it is introduced into the sedimentator through the drainage system, where the sedimentator removes larger particles and dirt in the water. Next, the rainwater passes through the filter to further remove fine particles, pollutants and impurities. The cleaned rainwater is finally stored in a specially designed water tank or pool, which can be used for irrigation, flushing, or even water supply when needed. For household use, this rainwater collection system helps to reduce urban stormwater pressure and mitigate the impact of rainwater runoff on the surrounding environment. At the same time, it is also a way to save water and improve the effective utilization of water resources. In some areas, governments and building codes also encourage or require the use of this system to promote sustainable urban development and water resource management. During use, various pollutants may accumulate on the roof surface, including dust, leaves, bird droppings, etc. Pollutants entering the rainwater collection system may affect the quality of rainwater, including causing odor, color changes or bacterial growth. Therefore, there is a special need for a rainwater collection and filtration device on the roof of a building.

Different particle impurities have different sizes during filtration. If the filter mesh is smaller, larger particles will cause the filter to be blocked, while larger ones will make the filtration effect on small particles poor. Utility Model Content
