Summary:PURPOSE: A non-power rainwater filtering and collecting device for functioning as initial rainwater exclusion, backwash, and overflow in a heavy rain is provided to effectively and easily perform a backwash, sedimentation, and filtration without using expensive devices. CONSTITUTION: A non-power rainwater filtering and collecting device comprises an initial rainwater exclusion module(1), an initial rainwater storage tank(2), a rainwater filter(3), and a rainwater storage tank(4). The initial rainwater exclusion module comprises a water collection weir(7), a screen(6), and a contaminant prevention pipe(8). The initial rainwater exclusion module excludes initial rainwater through a gutter(5). The initial rainwater storage tank comprises a flow maintenance small valve(9), an initial rainwater storage tank drain(10), and an initial rainwater storage tank outlet(11). The rainwater filter settles large and heavy particulate contaminants in a sedimentation space(13) and additionally filters the rainwater through a filter medium layer(14). The rainwater storage tank stores the rainwater which moves through a backwash water storage space(15) in the upper part of the filter medium layer and a rainwater filter outlet(17).
