  In the solar panel mount of Patent Document 1, the number of support columns in the front-rear direction is 2, and the base frame is supported by these support columns having different lengths, but the number of members of the solar panel mount is reduced. In order to simplify the structure, it is conceivable that the number of support posts in the front-rear direction is one, and a cane member is bridged between the support posts and the base frame in the front-rear direction.

  However, in the solar panel mount, it is required to support the base frame on which the solar panel is disposed on the support with a predetermined elevation angle with respect to the sun, and when the support is fixed to the ground, the support is centered on the vertical axis. It is fixed to the ground with a deviation angle in the turning direction, and it is also required to eliminate the influence of such a deviation angle, so that a predetermined elevation angle with respect to the sun can be obtained and the column centering on the vertical axis It must be devised so that the influence of the deviation angle in the rotation direction can be eliminated.

  The object of the present invention is to obtain a predetermined elevation angle with respect to the sun, and to influence the deviation angle of the support column centered on the vertical axis. The solution is to provide a solar panel mount that can be removed and connected to the column.

  The solar panel gantry according to the present invention is a solar panel gantry comprising a column fixed to the ground and a ground frame supported by the column and on which the solar panel is arranged. The cane member is spanned in the front-rear direction between the support column and the base frame, and the cane member and the base frame are connected to each other so as to be vertically rotatable. The cane member and the support column are connected by a rotation connecting unit, and the rotation connecting unit includes a left / right rotation center shaft that allows the cane member to rotate in the left / right direction with respect to the support column, and the cane member. And an up-and-down rotation center axis that can rotate in the up-down direction with respect to the support column, and the base frame is supported by the support column so as to be able to rotate up and down. It is characterized in that the height position of is changeable.

  In this solar panel gantry, the cane member and the base frame are connected to each other so as to be rotatable in the vertical direction, and the cane member and the support column are connected by the rotation connecting means. , Has a vertical rotation center axis that allows the cane member to rotate up and down with respect to the support column, and the base frame is supported by the support column so that it can be rotated up and down. Since the height position of the means can be changed, the elevation angle of the foundation frame with respect to the sun can be adjusted, whereby a predetermined elevation angle of the foundation frame can be obtained.

  Further, the rotation connecting means that connects the cane member and the support column has a left / right rotation center axis that allows the cane member to rotate in the left / right direction with respect to the support column. If the supporting column has a deviation angle in the rotation direction around the vertical axis, the effect of this deviation angle is eliminated by the left-right rotation around the left and right rotation center axis. A member and a support | pillar can be connected.

  The present invention described above can be applied to the case where the number of support columns in the left-right direction is one, and can also be applied to the case where there are a plurality of columns.

  When there are a plurality of support columns in the left-right direction, the cane member provided for each support column is bridged between the support column and the base frame in the front-rear direction.

  In the present invention, the left / right rotation center axis of the rotation connecting means may be disposed on the support column side, and the up / down rotation center axis may be disposed on the staff member side, or the left / right rotation center axis may be disposed on the staff member side. And the vertical rotation center axis may be arranged on the support column side.

  However, if the left and right pivot center axis is arranged on the side of the cane member and the up and down pivot center axis is arranged on the column side, the weight of the solar panel and the base frame acting on the pivot coupling means via the cane member, There is a possibility that a part of the rotation connecting means comes into contact with the support column. For this reason, it is preferable to arrange the left and right pivot center axis on the support material side and the vertical pivot center axis on the staff member side. According to this, the solar panel and the base frame can be used without causing the above problem. The weight can be effectively supported by the support post via the cane member and the rotation connecting means.

  In the present invention, the rotation connecting means can be configured in any form as long as it has a left-right rotation center axis and a vertical rotation center axis. And a connecting means for connecting the main body to the staff member.

  Thus, when the rotation connecting means includes the main body attached to the column and the connection means for connecting the main body to the cane member, the main body and the connecting means are centered on the left and right rotation centers. It can be connected via a shaft.

  Then, one of the main body and the connecting means can be provided with a cylindrical portion serving as a left-right pivoting central axis, and the other can be provided with a curved recess that is slidable in the left-right direction on the outer surface of the cylindrical portion. .

  Further, the cane member and the connecting means can be connected by a bolt whose axial direction is the horizontal direction, and this bolt can be used as the center axis of vertical rotation.

  Further, the connecting means may be formed by one member, but when the connecting means is formed by two connecting members having a symmetrical shape and one of these connecting members is turned upside down, You may make it become the same shape as the other.

  According to this, since two connection members can be made into the same member, commonization of a member (parts) is realizable.

  The present invention described above can be used for a large-scale power generation mega solar system in which a large number of solar panels are installed on the ground, and a small-scale power generation solar system in which a small number of solar panels are installed on the ground. Can also be used.

  Moreover, the column that is fixed to the ground and serves as a member for supporting the base frame may be a foundation pile driven into the ground with the head remaining on the ground, or on the ground. It may be a pillar erected from the foundation made of concrete or the like.

  Furthermore, fixing the column to the ground may be fixing the column to the ground via a building or the like installed on the ground. In other words, the column may be a column or the like standing on the roof of the building. .

  According to the present invention, the cane member spanned between the support frame supporting the base frame and the base frame is connected to the support post through the rotation connecting means having the left-right rotation center axis and the up-down rotation center axis. Thus, it is possible to obtain an effect that the cane member can be connected to the support column by obtaining a predetermined elevation angle of the solar panel and the base frame with respect to the sun and eliminating the influence of the shift angle of the support column with the vertical axis as the center.
