Ecological photovoltaic greenhouse based on comprehensive utilization of rainwater

Abstract

The invention discloses an ecological photovoltaic greenhouse based on comprehensive utilization of rainwater. The ecological photovoltaic greenhouse comprises one or more greenhouse units. Each greenhouse unit comprises two greenhouse bodies. The top surfaces of the greenhouse bodies comprise slope-type tops and arc-shaped tops. The arc-shaped tops of the two greenhouse bodies are adjacent. Separation walls are vertically arranged at connection positions between the slope-type tops and the arc-shaped tops. Solar panels are mounted at the slope-shaped tops. Beamers for automatically paying offand taking up heat-insulating films are mounted at the arc-shaped tops. The heat-insulating films are laid at the arc-shaped tops of the greenhouse bodies. A first U-shaped rainwater collection tankis arranged between the two greenhouse bodies. A second U-shaped rainwater collection tank is arranged on one side, away from the first U-shaped rainwater collection tank, of each greenhouse body. Theecological photovoltaic greenhouse has the advantages that the rainwater is recycled, good energy conversation and emission reduction effect is realized, and plant growth can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to an ecological photovoltaic greenhouse based on comprehensive utilization of rainwater. Background technique [0002] Rain harvesting agriculture has existed in the world for thousands of years. The rational and effective use of rainwater, as a part of water-saving irrigation, has extensive practical significance for the long-term and stable development of my country's agriculture. Especially since the 1970s, with the increasing world population and the increasingly prominent contradiction of water shortage, people have paid more and more attention to rain harvesting agricultural technology. The systematic research on rainwater utilization by scientists in our country began in the 1980s. At present, rainwater harvesting irrigation is mainly concentrated in the field of farmland irrigation, while there is less research on greenhouse rainwater harvesting. Therefore, ...

Problems solved by technology

The systematic research on rainwater utilization by scientists in our country began in the 1980s. At present, rainwater harvesting irrigation is mainly concentrated in the field of farmland irrigation, while there is less research on greenhouse rainwater harvesting. Therefore, it is urgent to design a system that can rationally use rainwater in my country Rainwater harvesting device for irrigation in greenhouses
