Solar cell panel automatic tracking device

The utility model discloses a solar cell panel automatic tracking device comprising a fixing support (1), a fixing platform (2) which is installed in the middle part of the fixing support (1), and a supporting platform (3) which is installed on the fixing platform (2). The supporting platform (3) is connected with a universal joint (4), and a cell panel tray (5) is installed on the supporting platform (3) via the universal joint (4). The reverse surface of the cell panel tray (5) is provided with four hinges which are respectively installed on four vertexes with the center of gravity of the solar cell panel tray (5) acting as the square center. The upper surface and the lower surface of the fixing platform (2) are respectively provided with a guide wheel (7), a tension wheel (8) and a stepping motor (9). The automatic tracking device is high in flexibility, high in tracking precision and wide in tracking range so that all-dimensional solar tracking can be realized. Besides, the automatic tracking device is higher in effective generating capacity so that the automatic tracking device can be applied to large-scale solar photovoltaic power stations, and thus the automatic tracking device has better economic benefit and environmental effect.
