Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a handheld single-roller photovoltaic panel cleaning machine. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic power generation is becoming more and more widely used. The cleanliness of the photovoltaic panel surface directly affects the power generation efficiency. However, in actual use, it is easily affected by pollutants such as dust, dirt, bird droppings, and water stains, which reduces its ability to absorb sunlight and leads to a decrease in power generation efficiency.

[0003] Currently, photovoltaic panel cleaning equipment faces numerous challenges. Manual cleaning is labor-intensive, inefficient, and costly, and its effectiveness is difficult to guarantee, especially for high-altitude or hard-to-reach photovoltaic panels. Common mechanical cleaning equipment often uses brushed motors, whose carbon brushes are prone to wear, resulting in high and cumbersome maintenance costs; their poor waterproofing poses safety hazards in humid environments. Some equipment lacks angle adjustment capabilities, or the adjustment process is complex and prone to errors, limiting the cleaning range and effectiveness. Regarding cleaning methods, some can only dry clean, failing to remove stubborn dirt; others consume large amounts of water, making them difficult to implement in water-scarce areas. Furthermore, most equipment is not modular, making parts replacement difficult and time-consuming, increasing maintenance costs and downtime. Therefore, designing and developing a high-efficiency, durable, easy-to-operate photovoltaic panel cleaning device adaptable to various scenarios has become a pressing engineering problem for the industry.
