The attached drawing is the utility model discloses a concrete embodiment, as shown in fig. 1-fig. 4, the utility model relates to a solar photovoltaic micro power station power supply unit, including a plurality of photovoltaic boards 9, photovoltaic board 9 adopts two-sided photovoltaic board, and series connection and/or parallelly connected combination form the photovoltaic board array, and photovoltaic board 9 and contravariant energy storage rack electric connection, contravariant energy storage rack have functions such as electric power storage and vary voltage for the power supply.

Photovoltaic board 9 is fixed in frame 13, and the side of two adjacent frames 13 is together fixed through first dead lever 10, and frame 13 both sides are equipped with support column 4, and frame 13 rotates through first connecting rod 11 to be connected on support column 4, if set up a plurality of frames 13 on the same straight line, can add support column 4 according to actual conditions between it in order to increase pivoted stability. The bottom center of frame 13 is equipped with the connecting piece, and the connecting piece is fixed on guide bar 12, and guide bar 12 articulates on slider 1, and guide bar 12 has certain supporting role, can offset partial gravity, alleviates driving motor 2's burden.

As shown in fig. 1, the driving device includes a driving motor 2, an output end of the driving motor 2 is connected with a lead screw 3, the other end of the lead screw 3 is connected with a lead screw seat 6, a threaded block 5 is connected on the lead screw 3 in a threaded manner, the driving motor 2 is connected with a controller, the driving motor 2 drives the threaded block 5 to move on the lead screw 3 through positive rotation or reverse rotation, thereby driving the sliding blocks 1 to move, two adjacent sliding blocks 1 are fixedly connected through a second connecting rod 8, thus, synchronous movement of the sliding blocks 1 can be realized, and the sliding blocks 1 are matched with the sliding grooves 7, so that the sliding blocks 1 can move more flexibly.

As shown in FIG. 4, the connecting member at the center of the bottom of the outer frame 13 includes a U-shaped connecting rod 15 fixed at the top of the guiding rod, two ends of the U-shaped connecting rod 15 are annular limiting blocks 18, and the annular limiting blocks 18 are nested in grooves at two ends of the connecting shaft 17 and can rotate around the grooves, so that the U-shaped connecting rod 15 and the connecting shaft 17 form a connecting rod structure.
