Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a rainwater collecting device for a concave roof 1 includes a roof 1, a water collecting tank 2 is disposed at an upper end of the roof 1, and a filter screen 3 is detachably connected to an upper end of the water collecting tank 2. The upper end of the roof 1 is positioned on two sides of the water collecting tank 2 and is respectively fixed with a sliding rail 4, two sides of the filter screen 3 are respectively fixed with more than two sliding blocks 5, and the sliding blocks 5 are respectively arranged on the sliding rails 4. The other two sides of filter screen 3 are fixed with the lantern ring 6 respectively on the side, and roof 1 is last and be located 2 both sides of water catch bowl and be fixed with reference column 7 respectively, and lantern ring 6 overlaps respectively and establishes on reference column 7.

2 upper ends of water catch bowl are fixed with mounting bracket 8, be fixed with motor 9 on mounting bracket 8, motor 9 sets up in the motor case, motor 9's output shaft and pivot 10 fixed connection, be equipped with stirring leaf 11 more than two in the

pivot

10, 11 height settings on the stirring leaf are all inequality, and the contained angle that 11 becomes of per two adjacent stirring leaves is the same, be fixed with water quality monitor 12 on the stirring leaf 11 respectively, whether water quality monitor 12 detectable rainwater reaches the standard of domestic water and industrial water, if detect not up to standard, explain the rainwater can not utilized. The side wall of the water collecting tank 2 is provided with overflow holes 13, the bottom of the water collecting tank 2 is provided with a water outlet tank 14, and the bottom of the water outlet tank 14 is provided with a first water outlet 15, a second water outlet 16 and a third water outlet 17. The first water outlet 15 is connected with a sewage pipe 19 through a first water outlet pipe 18, the second water outlet 16 is connected with an irrigation main pipe 21 through a second water outlet pipe 20, the irrigation main pipe 21 is connected with more than two irrigation branch pipes 22, the irrigation branch pipes 22 are buried at the root positions of ground plants, the third water outlet 17 is connected with a drainage pipe network 24 inside a building through a third water outlet pipe 23, and the first water outlet pipe 18, the second water outlet pipe 20 and the third water outlet pipe 23 are respectively provided with a control valve 25. The overflow hole 13 is connected to an overflow pipe 26, and the overflow pipe 26 communicates with the sewage pipe 19.
