Abstract

This invention belongs to the field of photovoltaic equipment, specifically providing an adjustable-angle photovoltaic device and method. The device includes a support mechanism, comprising a support base and a support shaft. The support shaft is driven by a rotation drive mechanism. A ring seat is mounted on the support shaft, and the ring seat is driven up and down by a vertical drive mechanism. The vertical drive mechanism includes a rack located on the outside of the support shaft, with gears meshing with the rack. The gear's rotation shaft is driven by a motor. A plurality of photovoltaic mechanisms are distributed along the axis of the support shaft between the ring seat and the top of the support shaft. Each photovoltaic mechanism includes a photovoltaic bracket and a photovoltaic panel mounted on the photovoltaic bracket. The photovoltaic bracket includes a support rod and a connecting rod. One end of the support rod is hinged to the ring seat, and the other end is hinged to the connecting rod. The other end of the connecting rod is hinged to a first hinge support at the upper end of the support shaft. The photovoltaic panel is mounted on the connecting rod. This device and method facilitate adjustment of the photovoltaic panel angle, allowing it to be in an extended or retracted state, improving flexibility and facilitating cleaning operations.
