Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, and in particular to a photovoltaic cleaning device with a blowing function. Background Technology

[0002] Cleaning photovoltaic (PV) panels is a crucial step in ensuring their efficient power generation. Currently, cleaning methods mainly include: manual cleaning, manual equipment cleaning, PV cleaning robot cleaning, and mechanized cleaning vehicle cleaning. Manual cleaning uses tools such as mops, brushes, or soft cloths; this method is simple and economical, but inefficient and struggles to remove stubborn stains. Manual equipment cleaning uses push-type or electric cleaning devices that spray high-pressure water or cleaning solutions; this method is more efficient and suitable for small-scale PV panels, but the existing equipment is relatively complex. PV cleaning robots can autonomously navigate and clean, offering strong adaptability, good cleaning results, and no damage to the PV panel surface. Finally, mechanized cleaning vehicle cleaning is suitable for large-scale mountainous PV power stations, offering high cleaning efficiency, but the equipment is expensive and has strict site requirements. Furthermore, in water-scarce areas such as deserts and plateaus, water cleaning is impractical, and these areas often experience strong winds and sandstorms, necessitating frequent cleaning.

[0003] Therefore, there is an urgent need to propose a photovoltaic cleaning device with a simple structure and reliable cleaning capability, which includes a purge function. Utility Model Content
