Roof rainwater collection device for green building

Abstract

The invention provides a roof rainwater collection device for a green building. Two sides of a roof board are equipped with flow guide frames. Middle positions of the flow guide frames are equipped with grooves. Anticorrosion boards are fixed at bottom positions in the interiors of the grooves. Sealing edges are distributed at edge positions of the anticorrosion boards. Edges of the sealing edgesare attached to two walls of the grooves. Front side positions of the flow guide frames are equipped with water outlet valve openings which communicate with the flow guide frames. Rainwater is collected by the flow guide frames such that rainwater is conveyed to the interior of a water storage tank through a connection pipe. Protecting edges enable limiting drums to be fixed at the water outlet valve openings. Foreign matter of rainwater in filter nets is filtered. Abrasion of the bottoms of the flow guide frames caused by long rainwater accumulation is avoided. The sealing edges are attachedto inner walls of the flow guide frames. The purpose of disinfecting is fulfilled by ultraviolet ray disinfection lamps in the interior of a top cover of the water storage tank. Therefore, water liquid in the interior of the water storage tank meets the household condition.

Description

technical field [0001] The invention relates to roof rainwater collection equipment for green buildings, which belongs to the field of green buildings. Background technique [0002] In the prior art, there is a lack of water resources and a low utilization rate of rainwater. In order to solve this problem, a rainwater collection and treatment equipment on the roof of a building is invented to collect and treat the rainwater on the roof for use as domestic water. The rainwater with more impurities is discharged, and the filter can simply process the rainwater to make the rainwater meet the domestic water standard. However, the traditional equipment has the problems that the filter cannot be replaced and the rainwater is inconvenient to sterilize. Therefore, a new equipment is needed to solve the above problems. question. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a roof rainwater collect...
