The elevation angle of the sun with respect to the sun can be fixed at that size.

  Further, even if the latitude on the earth is the same, the altitude of the south and middle of the sun changes depending on the season. Therefore, changing the elevation angle of the base frame 1 with respect to the sun by the rotating means B as described above is different from the season. It may be performed when it changes.

  For this reason, according to the present embodiment, the elevation angle of the base frame 1 with respect to the sun can be adjusted by the rotating means B according to the latitude and season on the earth where the solar panel mount is installed. Thus, it is possible to select an optimum elevation angle with respect to the sun of the base frame 1 that can improve the photovoltaic power generation efficiency.

  Moreover, in this embodiment, the base end part of the cane member 20 is attached to the base frame 1 by the ball joint means 22 of FIG. 5 and the band member 24 attached to the foundation pile 3 by tightening with the fastener 23. When the base frame 1 is rotated up and down with respect to the foundation pile 3 by the rotating means B in order to give the base frame 1 an appropriate elevation angle with respect to the sun, the nut 23B of the fastener 23 is connected. After adjusting the height position of the band member 24 in the foundation pile 3 by loosening the nut 23B, by tightening the nut 23B, the height position of the base end portion of the cane member 20 in the foundation pile 3 is adjusted to the base frame. It can be changed to an appropriate position corresponding to the elevation angle of 1.

  And when changing the height position of the base end part of the cane member 20 in the foundation pile 3 in this way, the connection part of the base end part of the cane member 20 and the foundation pile 3 is a ball joint means. Since this is a rotation connecting portion that can be rotated up and down by 22, this change and adjustment work can be performed as prescribed.

  Further, as described with reference to FIG. 4, the connecting portion between the cane member 20 and the base frame 1 is constituted by the fastener 21 made of a bolt and a nut, and this connecting portion is also centered on the shaft portion of the bolt of the fastener 21. Therefore, an operation of changing the height position of the base end portion of the cane member 20 in the foundation pile 3 to an appropriate position corresponding to the elevation angle of the foundation frame 1 is performed. The foundation pile 3 and the foundation frame are obtained by the rotation of the rotation connecting portion between the base end portion of the cane member 20 and the foundation pile 3 and the rotation of the rotation connecting portion between the cane member 20 and the foundation frame 1. 1 can be performed in a state of being connected to each other by the cane member 20.

  Further, the two rotating means A and B described above are L-shaped disposed between the foundation pile 3 and the foundation frame 1 in order to support the foundation frame 1 on the head of the foundation pile 3. The bracket member 9 having the shape is configured as a common component member. For this reason, the vertical direction or the substantially vertical direction is set to the vertical direction with respect to the foundation pile 3 by the bracket member 9 as the axial direction. The first rotation means A for enabling the rotation in the horizontal direction around the rotation center axis can be configured, and the bracket member 9 allows the base frame 2 to be horizontally or substantially horizontal with respect to the foundation pile 3. The second turning means B for enabling the turning in the vertical direction about the turning center axis as the axial direction can also be configured. For this reason, the structure of these first and second turning means A and B is also possible. Simplification can be achieved.

  Each foundation pile 3 driven into the ground 2 must have the same vertical length exposed upward from the ground surface 2A of the ground 2, but there is an error in the driving depth of each foundation pile 3 In addition, when there is a difference in the vertical length, the difference in the vertical length can be eliminated by the long hole 8 that is long in the vertical direction formed in the head member 6 of FIG.

  That is, in this embodiment, since the 2nd rotation means B is arrange | positioned at the upper surface of the head member 6, this 2nd rotation means B is the head of the foundation pile 3 via the head member 6. Since the height position of the head member 6 in the foundation pile 3 can be changed and adjusted by the long hole 8, it serves as the rotation center axis of the second rotation means B. Since there are a plurality of left and right foundation piles 3 parallel to the axial direction of the shaft portion 11C of the bolt 11, and there is an error in the driving depth of these foundation piles 3, the ground surface 2A If there is a difference in the vertical length of each foundation pile 3 exposed from the top to the top, the height of the second turning means B provided for each foundation pile 3 by the long hole 8 of the head member 6 The same position, so that these second rotating means B It is possible to support the base frame 1 at each foundation pile 3 of the head through.

  Furthermore, the foundation piles 3 in which a plurality of pieces are arranged in the left-right direction are not arranged accurately in the front-rear direction with respect to the core L as shown in FIG. When the deviation occurs, the deviation can be eliminated by the long hole 9 </ b> C of the bracket member 9.

  Moreover, when the space | interval of the left-right direction of each foundation pile 3 is not a predetermined magnitude | size, and the error has arisen in this space | interval, this error is the hole 17 demonstrated in FIG. This can be eliminated by a hole that is a long hole in the left-right direction, which is the length direction of the base frame 1.

  The present invention can be used for a solar panel mount installed on the ground, and can also be used for a mega solar system for large-scale power generation.
