Abstract

Disclosed is a solar power generation device capable of automatically removing snow and dust. The solar power generation device capable of automatically removing snow and dust comprises a solar photovoltaic module, a base and a rotating unit mounted on the base. The rotating unit is provided with a motor and two vertical columns; a rotatable support shaft is arranged between the two vertical columns and fixedly provided with a sleeve perpendicular to the support shaft; a rotating shaft is arranged inside the sleeve and born by two bearings at the upper end and the lower end of the sleeve; the solar photovoltaic module is fixed at the upper end of the rotating shaft; a telescopic double-cross axle type universal coupler is connected between the lower end of the rotating shaft and the output shaft of the motor. The solar power generation device capable of automatically removing snow and dust can simulate the turning actions of living beings and eliminate snow and dust on a photovoltaic battery panel through centrifugal force generated by forward and reverse rotation of the photovoltaic battery panel, thereby obtaining high snow removing effects. Compared with vibration type dust removal, the solar power generation device capable of automatically removing snow and dust has small or even no influence on structural safety of the photovoltaic module, thereby avoiding damage to the photovoltaic module as much as possible. Compared with contact type dust removal, the solar power generation device capable of automatically removing snow and dust avoids the problem of abrasion on the surface of the photovoltaic battery panel.

Description

technical field [0001] The present invention relates to a solar power generation device. Background technique [0002] The areas with relatively sufficient solar energy resources in my country are generally concentrated in the high-altitude areas in the west. Due to sufficient sunshine and less rainfall in these places, the photovoltaic panels in solar power generation devices are more likely to accumulate dust. In addition, in high-altitude areas, the snowfall in winter is relatively sufficient and the snow is difficult to melt, which will damage the battery. The panels receive sunlight and cause obstacles. When the accumulation of sand, dust and snow on the battery board reaches a certain level, it will have a significant impact on the power generation efficiency of the battery board and cause damage to the battery board. [0003] The utility model of Chinese patent application No. 200720036270.3 discloses a dust removal device for solar power generation panels. A hoist ...
