  The operation of the solar power generation device 1 will be described together with effects. The solar power generation device 1 rotates the mounting frame 3 with respect to the pedestal frame 4 and simultaneously rotates the expansion frame 5 with respect to the pedestal frame 4 while expanding and contracting, whereby the mounting frame 3 and the pedestal frame 4 are moved. The formed angle can be adjusted to an arbitrary angle including 0 degrees. After the tightening of the tightening members of the tube material 51 and the tube material 52 of the stretchable material 5 is released and the length is adjusted, the tightening member may be tightened and fixed again.

FIG. 12B shows a state where the elevation angle is 20 degrees, and FIG. 12C shows a state where the elevation angle is 10 degrees. These elevation angles are examples, and other angles can be taken stepwise or steplessly.

  The changing operation from the light receiving state of the solar power generation device 1 shown in FIG. 12 to the folded state shown in FIG. 9 will be described. First, when the fastening members of the pipe material 51 and the pipe material 52 of the elastic material 5 are released, and the pipe material 51 is slid and inserted into the pipe material 52, the elastic material 5 is shortened, and the solar panel 2 and the mounting frame 3 are placed in the horizontal position. And stop. At this time, the solar panel 2 and the mounting frame 3 are located in the inner region of the region defined by the base 6 and the base 7. Further, the upper surface of the solar panel 2 is disposed in the lower region of the horizontal plane of the engaging pieces 61 and 67 of the bases 6 and 7 and at the upper position of the bases 6 and 7. The reverse operation may be performed from the folded state of the solar power generation device 1 to the light receiving state.

  With respect to the photovoltaic power generation apparatus 1 that is folded in this way and is in a horizontal state in which the elevation angle of the light receiving surface of the solar panel 2 is 0 degree, the operation in the stacked state shown in FIG. It is only necessary to stack other solar power generation devices 1.

  When the plurality of solar power generation devices 1 are stacked, the pins 62 and 72 of the lower solar power generation device 1 can be engaged with the engagement holes 45 and 46 of the upper solar power generation device 1. That is, the pins 62 and 72 and the engagement holes 45 and 46 are vertically moved when the solar power generation device 1 is stacked up and down with the solar panel 2 and the pedestal frame 4 in parallel (see FIG. 13 and the like). Since the pedestal frames 4 to be arranged are respectively provided with engaging portions for engaging with each other, a plurality of photovoltaic power generators 1 can be engaged with each other, so that the stacked photovoltaic power generators 1 can be prevented from shifting in the horizontal direction.

  When this engagement is performed using a spring pin, there is no need to determine the position for inserting a locking piece or the like while lifting up the entire photovoltaic power generation device 1, and the upper photovoltaic power generation device 1 is placed horizontally. It can be done easily with a slight shift.

  FIG. 9 shows a state where the elevation angle of the solar panel 2 is 0 degree. At an elevation angle of 0 degrees, the solar power generation device 1 is almost the same size as the solar panel 2 in a plan view, and the thickness can be suppressed by about 2 to 4 times, so that it is very compact. At this time, as shown in FIG. 9, since it is in a substantially folded state, it is possible to store or carry a plurality of photovoltaic power generators 1 as shown in FIG. If the elevation angle is 0 degree, the mounting frame 3 can be superimposed on the pedestal frame 4 and folded, and the solar panel 2 and its framework can be stored in a more compact manner while being assembled. Since the photovoltaic power generation apparatus 1 can be moved and installed easily and quickly, the workability of storage and transportation is remarkably improved.

  Hereinafter, although the modified form of said solar power generation device 1 is demonstrated, about a member same as the solar power generation device 1, only a different point is described by using description. The photovoltaic power generation apparatus 101 shown in FIGS. 14 and 15 has the two photovoltaic power generation apparatuses 1 arranged side by side in the lateral direction, and a plurality of mounting frames 103 are arranged in parallel on the pedestal frame 104.

Cutout portions 106 a and 107 a for engaging with the long connecting members 191 and 192 are provided outside the lower ends of the first pedestal 106 and the second pedestal 107, respectively. For this reason, there exists an effect which can maintain compactness by accommodating the connection elongate member 191,192 in the location which is not conspicuous.

  In addition, since the long connecting members 191 and 192 are arranged in the notches 106a and 107a below the first bases 106 and 107, the occupied volume is reduced. In this modified embodiment, the pedestal frame 4 may be configured in advance to be twice as large as the left and right, and the two attachment frames 3 and the solar panel 2 may be provided side by side.

  A photovoltaic power generation apparatus 201 according to another modification will be described with reference to FIG. In the solar power generation device 1 described above, the two solar panels 2 are juxtaposed in parallel with their short sides, but here the three solar panels 202 are arranged with their long sides up and down. Adjacent to each other. Moreover, since the solar panel 202 protrudes from the attachment frame 233, the amount of power generation can be increased.

  A photovoltaic power generator 301 according to another modification will be described with reference to FIG. In this configuration, the photovoltaic power generation apparatus 201 is further juxtaposed in the horizontal direction like the above-described photovoltaic power generation apparatus 101. At this time, longer connecting long members 391 and 392 are used. Thereby, it can respond to a large capacity | capacitance electric power generation.

  These modified forms can be used by diverting the same members as those of the solar power generation apparatus 1 described first, and can be used in various ways according to the installation conditions together with the adjustment of the elevation angle of the solar panel 2. It is something that can be done.

  The embodiment of the present invention is not limited to the above-described embodiment, and modifications and the like can be made without departing from the technical idea of the present invention. Moreover, those modifications, equivalents, and the like are also included in the technical scope of the present invention, and can take various forms as long as they belong to the technical scope. For example, the first pedestal 6 and the second pedestal 7 are provided at both ends of the pedestal frame 4, but the present invention is not limited to this. When the pedestal frame 4 is provided with pedestals 6 and 7 having a horizontal plane and the solar panel 2 and the pedestal frame 4 are arranged in parallel by reducing the stretchable material 5, the upper surface of the solar panel 2 is placed on the pedestal 6. However, the present invention is not limited to this and may be disposed in an upper region from the horizontal plane. The first pedestal 6 has two functions such as the connection of the mounting frame 3 and the pedestal frame 4 and the second pedestal 7 connects the pedestal frame 4 and the telescopic frame 5 and enables stacking.
