  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a photovoltaic power generation apparatus according to an embodiment of the present invention, and FIG.

  Reference numeral 1 denotes a solar power generation device, which extends in parallel and is provided with floating bodies 3 at regular intervals with respect to the connecting member 2, and at least supports both side portions of the gantry 5 on which the solar power generation panel 4 is placed. Two floating body units 6 and 6 and a gantry support base 7 provided on each floating body 3 and capable of supporting the legs 5a of the gantry 5 are provided. Since this solar power generation device 1 has the floating body units 6 and 6 as a support base, it can be installed not only on ordinary flat land but also in wetlands such as fallow fields, ponds, and soft muds. Note that the gantry 5 has a rectangular shape having substantially the same size as that of the photovoltaic power generation panel 4 including a plurality of cells in plan view.

  The connecting member 2 is formed by connecting a plurality of connecting pipes 11 having flange portions 11a at end portions, and a partition disk between the flange portions 11a and 11a connected to each other by a fastener such as a bolt and a nut. 12 is provided. Two floating bodies 3, 3 are provided in one connection pipe 11, and the interval between the floating bodies 3, 3 corresponds to the length of the gantry 5 (solar power generation panel 4) in the extending direction S 1 of the floating body unit 6. Yes. And the space | interval of the floating body unit 6 respond | corresponds to the width | variety of the mount frame 5 (solar power generation panel 4) substantially. Therefore, the four corners of the gantry 5 (solar power generation panel 4) are supported by the floating body 3.
