When using this embodiment, the staff pulls out the drawer frames 2 on both sides of the box body 1 out of the box body 1, then sets the photovoltaic panel 3 upward, and receives solar energy through the photovoltaic panel 3 for power generation work. In order to improve the power generation efficiency, the side plate 21 can be folded outward so that the photovoltaic panel 3 inside the side plate 21 faces upward and conducts photovoltaic power generation work together. When the environment does not meet the conditions for photovoltaic power generation, the staff can open the cabinet door 0 and generate mechanical energy through the mechanical power generation device 10; part of the electric energy generated by the mechanical power generation device 10 and the photovoltaic panel 3 is stored through the energy storage device 12.
