Water circulation device for photovoltaic greenhouses

Abstract

The invention relates to the technical field of greenhouses, and especially relates to a water circulation device for photovoltaic greenhouses. The water circulation device includes a greenhouse frameand a ceiling installed above the greenhouse frame; a water tank is installed at the bottom of a greenhouse; main water pipes and water-returning pipes are fixed on the greenhouse frame; water distribution pipes are connected between the main water pipes and the water-returning pipes; the water distribution pipes include multiple water spraying and distribution pipes; nozzles for spraying water in the greenhouse are installed on the water spraying and distribution pipes; a water curtain wall is installed on one end of the greenhouse; a top water pipe communicating with the main water pipes isinstalled on the water curtain wall of the greenhouse frame; the top water pipe is provided with spraying holes for spraying water to the water curtain wall; fans are installed opposite the water curtain wall of the greenhouse; flexible photovoltaic assemblies are installed on the ceiling of the greenhouse; the upper part of the ceiling is provided with a cleaning water pipe for spraying water tothe flexible photovoltaic assemblies; the cleaning water pipe communicates with the main water pipes; and the ceiling is provided with a water recycling structure. Thus, the problems of hard coolingof photovoltaic greenhouses and low water resource utilization rates during production can be made up.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a water circulation device for a photovoltaic greenhouse. Background technique [0002] At present, photovoltaic photovoltaic greenhouses have gradually become new things that apply new energy sources to promote sustainable agricultural development. The advantage of the photovoltaic greenhouse is that it has a large operating space and stable environmental performance in the greenhouse, which can realize three-dimensional planting of vegetables, fruits and flowers. With the declining price of photovoltaic panel components, the combination of cost, technical advantages and greenhouses will guide the development of photovoltaic greenhouses into a new period of development. [0003] However, the water resources inside the photovoltaic greenhouse have not yet achieved efficient use of water resources. Traditional ground irrigation is still used for irrigation, including border i...
