For example, when the spool 20 rotates clockwise, the photovoltaic body 10 may be converted from the folded state to the unfolded state, so that the photovoltaic body 10 is unfolded along the first direction a, the unfolding of the photovoltaic body 10 may utilize the elastic restoring force of the rope 30, and the elastic restoring force acts on the connecting element 60 connected to the photovoltaic body 10 at the other end, so that the connecting element 60 moves towards the end far away from the spool 20 along the first direction a, and the photovoltaic body 10 is driven to be unfolded; when the reel 20 rotates counterclockwise, the photovoltaic body 10 may be transformed from the unfolded state to the folded state to fold the photovoltaic body 10 in the first direction a.
