Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic brackets, and in particular to a flexible bracket photovoltaic cleaning device. Background Art

[0002] A flexible photovoltaic bracket is a photovoltaic bracket made of elastic material. It is a large-span multi-span structure. Prestressed steel wire ropes are usually tensioned between the fixed points at both ends. The fixed points use rigid structures and outer inclined steel strands to provide support reaction forces. The span of the cable structure is generally between 20 meters and 40 meters, and can be up to 100 meters. At the same time, the components can be 20 meters to 30 meters above the ground. Snow accumulation on the surface of photovoltaic panels in winter is a common problem. Heavy snow will impose additional weight on photovoltaic panels, especially under extreme weather conditions, which may cause damage to photovoltaic panels or structural deformation. Traditional snow removal methods mainly use simple snow scraping tools to deal with snow on the surface of photovoltaic panels. Under low temperature conditions, snow may freeze to form a hardened ice layer that is not easy to remove, further affecting the performance of photovoltaic panels. Traditional cleaning methods are difficult to effectively deal with hardened snow. Secondly, the specifications of photovoltaic panels installed in different sites are different, and the transmission cleaning tools are less flexible and difficult to adapt to photovoltaic panels of different specifications.
