AI Technical Summary

Technical Problem

When watering and cooling photovoltaic panels, the existing photovoltaic greenhouse rainwater recycling system mainly relies on air cooling or circulating water cooling, and lacks effective rainwater recycling and photovoltaic panel cleaning functions.

Method used

A photovoltaic greenhouse rainwater recovery system is designed. The rainwater is divided into multiple water storage areas through the inclined glass rain-receiving surface and partition frame. By rotating the set baffle and transmission rod, the rainwater sprinkler and the photovoltaic panels are realized.

Benefits of technology

It realizes efficient rainwater recycling and automatic cleaning of photovoltaic panels, improves the working efficiency and rainwater utilization rate of photovoltaic panels, and avoids the problem of silt and sand accumulation on the rain surface of the glass on the top of the greenhouse.

Abstract

The invention discloses a photovoltaic greenhouse rainwater recovery system and a photovoltaic greenhouse, and relates to the technical field of combination of photovoltaic power generation and agricultural planting. The rain-proof window comprises a glass rain-receiving surface which is obliquely arranged, and further comprises a plurality of separation frames for separating the glass rain-receiving surface into a plurality of strip-shaped rain-receiving surfaces. According to the invention, the first water storage baffle is rotatably arranged between the first water storage area and the second water storage area, and the second water storage baffle is rotatably arranged between the second water storage area and the third water storage area, so that the first water storage baffle and the second water storage baffle can release rainwater above to water and clean the photovoltaic panel after being rotatably opened; and meanwhile, due to the design of a transmission rod, when the first water storage baffle or the second water storage baffle rotates downwards to release rainwater, a driving rectangular frame drives bristles to brush the upper surface of the photovoltaic panel, so that after the upper surface of the photovoltaic panel is irrigated and flushed by the rainwater, the rainwater can be brushed by the bristles, and the capability of better cleaning dirt on the surface of the photovoltaic panel is obtained.
