Photovoltaic string cleaning and irrigation integrated device for agriculture and light complementation and cleaning method

Abstract

The invention discloses a photovoltaic string cleaning and irrigation integrated device for agriculture and light complementation and a cleaning method; a cleaning water pipe is arranged above a photovoltaic string, the cleaning water pipe is connected with a water tank through a water feeding pipe, and a water pumping motor is arranged in the water tank; a waste liquid collecting tank with a slope is arranged below the photovoltaic string in the length direction of the photovoltaic string, the bottom of the waste liquid collecting tank is connected with a waste liquid storage tank and an irrigation nozzle through a three-way adapter via corresponding electromagnetic valves, and a dust monitor is arranged on the photovoltaic string. And the dust monitor is respectively connected with the water pumping motor and an electromagnetic valve through a controller. According to the invention, classified cleaning of pollutants in the photovoltaic string can be realized, and the cleaning effect is good; secondary utilization of wastewater for agricultural irrigation can be realized, and energy conservation and environmental protection are realized; the integration level is high and installation and use are convenient.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment for photovoltaic modules, and in particular relates to an integrated device for cleaning and irrigating photovoltaic strings for agricultural and photovoltaic complementarity and a cleaning method. Background technique [0002] As a clean energy source, solar energy has gained the attention of countries all over the world. Since the photovoltaic power station is built outdoors, frequent component pollution problems have occurred in recent years, resulting in a decrease in the irradiance received by the photovoltaic power station, reducing the power generation of the components, and even affecting the service life of the components. Due to the different weather conditions in different seasons and the different content of particulate matter in the air in different regions, it is difficult to achieve reasonable, efficient and economical treatment.

Problems solved by technology

Since the photovoltaic power station is built outdoors, frequent component pollution problems have occurred in recent years, resulting in a decrease in the irradiance received by the photovoltaic power station, reducing the power generation of the components, and even affecting the service life of the components

Due to the different weather conditions in different seasons, the content of particulate matter in the air in different regions is also different, making it difficult to achieve reasonable, efficient and economical treatment.

[0003] Most of the current cleaning methods are relatively simple, mainly relying on tap water to clean the components, but due to the different nature of the pollutants, sometimes the cleaning effect with clean water is poor, and the purpose of cleaning cannot be achieved

Moreover, the cleaning liquid is not properly applied after cleaning, and the purpose of energy saving and environmental protection cannot be achieved
