Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, and more specifically, to a cleaning mechanism for a photovoltaic power generation device. Background Technology

[0002] In the field of photovoltaic power generation, the cleanliness of the photovoltaic panel surface directly affects its photoelectric conversion efficiency. Since photovoltaic panels are usually installed outdoors and exposed to the natural environment for a long time, they will inevitably be contaminated with pollutants such as dust, bird droppings, and leaves. These pollutants will block sunlight, reduce the absorption of light energy by the photovoltaic panel, and thus reduce the power generation.

[0003] Handheld cleaning devices have garnered widespread attention due to their portability. However, existing handheld photovoltaic panel cleaning devices have some shortcomings in their design and use. The replacement and disassembly of the cleaning rollers in some handheld devices are extremely cumbersome, requiring various specialized tools such as screwdrivers and wrenches, increasing maintenance costs and difficulty. Therefore, we propose an improvement to this, creating a cleaning mechanism for photovoltaic power generation devices. Utility Model Content

[0042] During disassembly, disconnect the hook-and-loop fastener body 112 from the hook-and-loop hook 113, then pull the second support plate 101 away from the first support plate 1, so that the slot 106 separates from the shaft 104 and the cleaning roller 105 can be removed. During installation, insert the slot 106 and the shaft 104 together, and insert the second limiting groove 111 and the first limiting protrusion 107 together, and insert the second limiting protrusion 110 and the first limiting groove 108 together.
