The green building designed roof rainwater collection and recycling structure of claim 1, wherein: the interior bottom of cistern (7) be fixed with agitator motor (21), agitator motor (21) is connected with external power supply, be fixed with square shaft (22) on the output shaft of agitator motor (21), all be equipped with a plurality of stirring leaf (23) from last equidistance down on the left and right sides wall of square shaft (22), the outside cover of square shaft (22) is equipped with square sleeve pipe (24), the slip groove cover on square sleeve pipe (24) both sides wall is established on a stirring leaf (23) of square shaft (22) both sides, all be fixed with a plurality of stirring leaf (25) from last equidistance down on two outer walls around square sleeve pipe (24), the upper end of square sleeve pipe (24) has connect locating plate (26) through the bearing soon, this locating plate (26) and the interior perisporium fixed connection of inserting frame (9), at the in-process of retaining, add neutralization liquid, restart agitator motor (21), agitator motor (21) drives square shaft (22) and rotates, square shaft (22) drive square sleeve pipe (24) and stirring leaf (23) rotate, square sleeve pipe (24) drive No. two stirring leaves (25) and rotate, and then stir the water in cistern (7), make water and neutralization solution intensive mixing, after the water level rose, insert frame (9) and drive locating plate (26) rebound, locating plate (26) drive square sleeve pipe (24) rebound, make a sliding tray of stirring leaf (23) on square sleeve pipe (24) slide, advance not influence square sleeve pipe (24) and remove, conveniently stir.

7. The green building designed roof rainwater collection and recycling structure of claim 1, wherein: in rainy days, rainwater is accumulated in a groove of a roof (2) and irrigates green plants (3), after irrigation, redundant rainwater flows to the bottom of the groove on the roof (2), then flows into a collecting pipe (4) on the right side and then flows into a connecting pipe (5) on the rear side of the roof (2), finally enters an insertion frame (9) through an extension pipe (6), and is filtered through a filtering frame (14), and then enters a reservoir (7), when the water level reaches a water level sensor (15), the water level sensor (15) transmits a signal to a controller (16), the lifting mechanism (13) is started through the controller (16), the lifting mechanism (13) drives a lifting plate (11) to move upwards, the lifting plate (11) drives the insertion frame (9) to move upwards until the water level sensor (15) is higher than the water level, the lifting mechanism (13) is closed through the controller (16), and the peripheral wall of the insertion frame (9) is propped against the inner peripheral wall of the reservoir (7) through the sealing ring (10), so that the phenomenon that excessive rainwater flows out from a gap is avoided, and the water storage capacity is increased.
