Title: SWEEPING DEVICE FOR PHOTOVOLTAIC PANEL
Abstract:
Provided is a sweeping device for a photovoltaic panel, applied to a photovoltaic unit composed of a sequentially arranged plurality of photovoltaic panel arrays. The sweeping device for the photovoltaic panel comprises a guide rail mechanism formed by an upper rail and a lower rail respectively arranged at upper and lower sides of the photovoltaic panel arrays, and a plurality of scraper mechanisms for sweeping the photovoltaic unit. Each of the photovoltaic panel arrays at most corresponds to one scraper mechanism. The scraper mechanisms are slidably arranged on the guide rail mechanism corresponding to any photovoltaic panel array. The sweeping device further comprises: a cord mechanism for driving the scraper mechanisms to perform reciprocating motion on the photovoltaic unit, and a driving mechanism connected to the cord mechanism. Compared with the prior art, the driving mechanism can be used to drive the cord mechanism, and the scraper mechanisms perform reciprocating motion on the photovoltaic unit with the unwinding rope and winding rope of the cord mechanism so as to complete the sweeping of surfaces of the photovoltaic panel arrays. In contrast with the use of a robot, the sweeping device not only has a simple structure and is low cost, but also improves the sweeping efficiency of the whole photovoltaic unit.
