Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cleaning auxiliary equipment, and in particular to an unmanned aerial vehicle photovoltaic inspection and cleaning device. Background Art

[0002] The scale of the photovoltaic industry continues to expand, and the demand for photovoltaic operation and maintenance inspections is increasing year by year. The traditional method of photovoltaic panel inspection is for maintenance personnel to inspect the photovoltaic panels with handheld scanners or vehicles, which has low inspection efficiency and high total cost. At the same time, the existing method of cleaning dust and dirt is for maintenance personnel to go to the location of the photovoltaic components and use special tools to clean them, which is not only time-consuming and labor-intensive, but also inefficient and has certain safety hazards.

[0003] Since photovoltaic arrays are used in outdoor environments, dust particles and bird droppings in the atmosphere make it easy for dust and dirt to accumulate on the surface of photovoltaic modules. According to experimental tests, dust and dirt on the surface of photovoltaic modules will cause a loss of solar radiation of 5%-30%. On the one hand, dust and dirt will block sunlight, reduce the transmittance of the surface of photovoltaic modules, and reduce the amount of solar radiation on the surface; on the other hand, it will cause the heat transfer form of the surface to change. Dust and dirt absorb solar radiation and convert it into their own heat energy, while blocking the heat dissipation of the photovoltaic panel surface. The specific performance is as follows:

[0004] First, dust and dirt contain a large amount of calcium and magnesium oxides. When it rains, a small amount of calcium and magnesium ions will dissolve in the rainwater, and over time, thick and hard calcium and magnesium scale will form on the surface of the photovoltaic modules, seriously affecting the power generation efficiency of the photovoltaic modules and causing problems such as hot spots.

[0005] Second, dust and dirt will convert part of the absorbed solar radiation into their own heat energy, increase the temperature of the photovoltaic modules, and form a covering and heat preservation effect, which affects the heat dissipation of the photovoltaic modules. The temperature inside the photovoltaic panels increases, which will reduce the photovoltaic efficiency.

[0006] Third, if the dust and dirt on the surface of photovoltaic modules are not cleaned in time, they will accumulate to a certain thickness, making it more likely for sunlight to be reflected, scattered and absorbed. Utility Model Content
