Roof rainwater collecting and recycling system

Abstract

A roof rainwater collecting and recycling system comprises a rainwater gathering unit, a rainwater collecting unit, a spraying unit, a drainage unit and a glass cleaning unit. The bottom of the rainwater gathering unit is communicated with the rainwater collecting unit through a pipeline, the rainwater collecting unit is communicated with the spraying unit though a pipeline, and a plurality of spraying pipes are arranged at the bottom of the spraying unit. The glass cleaning unit comprises a guide track, a sliding cross rod, an elastic wiping bar and a pull-up mechanism. According to the roof rainwater collecting and recycling system, rainwater is collected through the rainwater gathering unit and the rainwater collecting unit, then the rainwater is used for washing glass through the spraying unit, and thus water resources are saved; the sliding cross rod moves downwards or upwards through the action of gravity or the pull-up mechanism and drives the elastic wiping bar to move downwards or upwards relative to window glass, and the elastic wiping bar wipes the window glass. The sliding cross rod in the glass cleaning unit moves downwards through the gravity to wipe window glass, and power does not need to be additionally provided.

Description

technical field [0001] The invention relates to the technical field of domestic wastewater recycling and reuse, in particular to a roof rainwater collection and reuse system. Background technique [0002] With the acceleration of the urbanization process, the shortage of water resources and the deterioration of the ecological environment have emerged, and the utilization of urban rainwater as water resources has rapidly developed all over the world. Many developed countries such as Japan, Australia and Germany are very concerned about the use of rainwater. For example, Japan combines the existing reclaimed water projects to build rainwater-irrigated "sky gardens" on urban roofs, and install rainwater collection devices in buildings to cooperate with reclaimed water projects. Play a role; Germany listed the management and utilization of rainwater as one of the three major issues of water pollution control in the 1990s in the late 1980s. At present, the utilization rate of rain...

Many developed countries such as Japan, Australia and Germany are very concerned about the utilization of rainwater. For example, Japan combines the existing reclaimed water projects to build rainwater-irrigated "sky gardens" on urban roofs, and install rainwater collection devices in buildings to cooperate with reclaimed water projects. Play a role; Germany listed the management and utilization of rainwater as one of the three major issues of water pollution control in the 1990s in the late 1980s. At present, the utilization rate of rainwater in my country is very low. Compared with developed countries, it can be developed and utilized. The potential of rainwater is great, and the rational collection and utilization of rainwater is of great significance to alleviate the tension of water resources
