The invention discloses an overwater photovoltaic platform, and relates to the technical field of photovoltaic platforms. The device comprises a plurality of supporting frames, and anchoring seats are fixedly connected to the bottoms of the supporting frames. The photovoltaic panel cleaning device is provided with the cleaning
brush, the driving piece and the auxiliary
assembly, by starting the driving piece, the cleaning
brush can be driven to effectively clean the surface of the photovoltaic panel, a worker does not need to go to the site for manual cleaning, the requirement for manual cleaning is reduced, the maintenance cost is reduced, cleaning of the photovoltaic panel can be kept, and the power generation efficiency is improved; in addition, the auxiliary
assembly can be driven to move together while the cleaning
brush is used for cleaning, the surface of the photovoltaic panel can be effectively wiped and cleaned again, the cleaning efficiency is improved, through full-automatic cleaning, the time and labor needed by manual cleaning can be reduced, meanwhile, the consistency and thoroughness of cleaning are guaranteed, and the cleaning efficiency is improved. In addition, the
safety risk during manual cleaning is reduced, and particularly the risks of slipping, falling and the like possibly encountered during operation on the water surface are reduced.
