Description

Technical Field

[0001] The present invention relates to the field of surface defect visual monitoring equipment, and in particular to a photovoltaic panel surface defect visual monitoring equipment. Background Art

[0002] With the growing global demand for clean energy, photovoltaic power generation, as a renewable, pollution-free energy source, has been widely used and rapidly developed. As the core component of photovoltaic power generation systems, the surface cleanliness and performance of photovoltaic panels are directly related to power generation efficiency and stable system operation. However, during actual operation, the surface of photovoltaic panels is easily adhered to pollutants such as dust, dirt, and bird droppings. These pollutants reduce the light transmittance of photovoltaic panels, thereby affecting their photoelectric conversion efficiency and resulting in a decrease in power generation. In addition, photovoltaic panels may develop surface defects such as scratches and cracks during long-term use, which can also affect the performance and service life of photovoltaic panels.

[0003] Currently, cleaning and defect monitoring for photovoltaic panel surfaces primarily rely on manual labor. Manual cleaning is not only inefficient and labor-intensive, but also presents numerous inconveniences when cleaning large outdoor panels, making it prone to incomplete cleaning and missed areas. Furthermore, manual monitoring for photovoltaic panel surface defects also faces limitations such as low efficiency, poor accuracy, and difficulty in real-time monitoring. As the scale of photovoltaic power plants continues to expand, this manual maintenance method is no longer able to meet the demands of efficient and automated operation for modern photovoltaic power plants.

[0004] With the continuous advancement of technology, some automated cleaning and monitoring equipment has gradually begun to be used in photovoltaic power plants. However, most existing automated equipment suffers from limited functionality, poor applicability, and high maintenance costs. For example, some cleaning equipment can only clean the surface of photovoltaic panels and cannot simultaneously detect surface defects. Meanwhile, some monitoring equipment, while able to detect defects, cannot clean the surface of photovoltaic panels and is prone to malfunction in complex outdoor environments, requiring frequent manual maintenance. Furthermore, existing equipment has certain limitations when adapting to photovoltaic panels of different sizes and installation angles, and its structure cannot be flexibly adjusted to suit various practical application scenarios.

[0005] Therefore, it is necessary to propose a photovoltaic panel surface defect visual monitoring device to solve the above problems. Summary of the Invention
