  DESCRIPTION OF EMBODIMENTS Embodiments of a solar panel mount according to the present invention will be described with reference to the drawings. FIG. 1 is a view showing a photovoltaic power generation panel mount 80 according to the present invention. Moreover, FIG. 2 is a figure which shows the use condition of the stand 80 for photovoltaic power generation panels which concerns on this invention. In FIG. 2, the photovoltaic power generation panel 10 is represented by a transparent line with a broken line. Further, in the following description, the front side of the photovoltaic power generation panel gantry 80 means the front side of the photovoltaic power generation panel 10, and the rear side means the front side of the front side.

  1 is a base block portion 30 having a front pillar portion 32a and a rear pillar portion 32b, and a front side that is installed on the front pillar portion 32a so that the height can be adjusted. The column 34a, the rear column 34b installed on the rear column 32b so as to be adjustable in height, the front horizontal frame 36a installed on the front column 34a for fixing the photovoltaic power generation panel 10, and the rear column 34b And a rear lateral frame 36b for fixing the photovoltaic power generation panel 10 installed therein.

  The foundation block portion 30 is made of, for example, reinforced concrete, and the front pillar portion 32a rising upward is integrally formed on the front side portion of the foundation block portion 30 as described above. In addition, a rear pillar portion 32 b that rises upward is integrally formed on the rear side portion of the base block portion 30. Further, a plurality of screw holes for attaching the front column 34a and the rear column 34b are formed in the front column 32a and the rear column 32b. The solar power generation panel 10 is often installed at an angle of about 30 ° with respect to the ground. Therefore, it is preferable that the difference in height between the top surfaces of the front column portion 32 a and the rear column portion 32 b is about 30 ° with respect to the bottom surface of the basic block portion 30. Alternatively, the anchor block 48 may be provided at the bottom of the foundation block 30 and the anchor 7 may be driven into the ground through the anchor hole 48 to more firmly fix the foundation block 30. According to this configuration, it is possible to further increase the allowable value of the wind load applied to the solar power panel gantry 80.

  The front column 34a and the rear column 34b are made of a metal material, and for example, the vertically long slot 42 is formed to correspond to the screw holes of the front column 32a and the rear column 32b. Then, by inserting a screw or the like into the long hole 42 and screwing it into the screw holes of the front column portion 32a and the rear column portion 32b, the front column 34a and the rear column 34b are connected to the front column portion 32a and the rear column portion 32b. Fix each one. Note that the front column 34a and the rear column 34b are independent of the height of the foundation block 30 (the front column 32a and the rear column 32b) by changing the position of the elongated hole 42 to be screwed. Adjustments can be made.

  Attachment stays 44a and 44b are respectively installed on the upper ends of the front column 34a and the rear column 34b in a rotatable state. The front lateral frame 36a and the rear lateral frame 36b are installed on the front column 34a and the rear column 34b via mounting stays 44a and 44b. In addition, as shown in FIG. 2, a plurality of photovoltaic power generation panel mounts 80 are basically arranged in the horizontal direction. Therefore, the front side horizontal frame 36a and the rear side horizontal frame 36b are installed so as to be bridged over the respective mounting stays 44a, 44b of the photovoltaic power generation panel mount 80 arranged in the horizontal direction. However, in a configuration provided with a safety mechanism to be described later, the front lateral frame 36a is placed on the mounting stay 44a and then locked by the hook portion 52, and is not directly fixed to the mounting stay 44a.

  A vertical frame 46 is installed between the front horizontal frame 36a and the rear horizontal frame 36b so as to bridge the both. A plurality of the vertical frames 46 are installed so as to be arranged on at least both sides of the photovoltaic power generation panel 10. Then, by fixing the photovoltaic power generation panel 10 to the vertical frame 46, the photovoltaic power generation panel 10 is fixed to the photovoltaic power generation panel mount 80.

  In FIG. 2, four photovoltaic power generation panel mounts 80 are arranged in the horizontal direction, and two photovoltaic power generation panels 10 are vertically installed between the photovoltaic power generation panel mountings 80. An example is shown in which a total of six panels 10 are arranged in three rows and two rows. However, the number of installed photovoltaic power generation panels 10 is not particularly limited to this.

  Next, a method for installing the solar panel gantry 80 will be described. First, the ground on which the base block unit 30 is installed is leveled. Next, the foundation block portion 30 of the photovoltaic power generation panel mount 80 is disposed at a predetermined position. At this time, if necessary, the anchor 7 is driven into the ground through the anchor hole 48 to fix the foundation block 30. Next, the front horizontal frame 36a is installed on the mounting stay 44a of the front column 34a of the foundation block 30. At this time, the mounting height of the front column 34a is adjusted, and the position of the front horizontal frame 36a is adjusted so as to be substantially parallel to the ground, for example. Before and after this, the rear lateral frame 36b is installed on the mounting stay 44b of the rear column 34b. At this time, the mounting height of each of the rear columns 34b is adjusted, and the position of the rear horizontal frame 36b is adjusted so as to be substantially parallel to the front horizontal frame 36a. Further, the mounting height of the front column 34a and the mounting height of the rear column 34b are adjusted so that the height positions of the front horizontal frame 36a and the rear horizontal frame 36b are, for example, 30 ° with respect to the ground. Next, a predetermined number of vertical frames 46 are installed so as to span the front horizontal frame 36a and the rear horizontal frame 36b. As a result, the installation of the solar power generation panel mount 80 is completed. Next, the photovoltaic power generation panel 10 is fixed to the vertical frame 46. Thereby, the solar power generation panel 10 is installed on the stand 80 for solar power generation panels.

  Thus, the foundation block 30 of the photovoltaic power generation panel gantry 80 according to the present invention has a configuration in which the front foundation block and the rear foundation block in the conventional gantry are connected. For this reason, position adjustment with a front side foundation block and a back side foundation block is unnecessary, and installation of the foundation block part 30 can be performed easily. In addition, since the height of the front column 34a and the rear column 34b can be adjusted individually, the horizontal frames 36a, 36b can be formed even if the foundation block 30 is slightly moved up and down due to slight unevenness and inclination on the ground. In addition, the position of the vertical frame 46 can be adjusted easily.

  In addition, the photovoltaic power generation panel gantry 80 according to the present invention may be provided with the following safety mechanism during strong winds. As shown in FIG. 3 (a), the safety mechanism of the solar panel pedestal 80 includes a hook portion 52 for locking the front side horizontal frame 36a, and the hook portion 52 attached to the locking side of the front side horizontal frame 36a. And a damper member 56 that suppresses sudden vertical movement of the photovoltaic power generation panel 10. When this safety mechanism is provided, it is preferable to use a cylindrical pipe for the front lateral frame 36a. Moreover, it is good also considering only the area | region which the hook part 52 latches as cylindrical shape. Further, a cylindrical pipe may be fixed in parallel to the front lateral frame 36a, and the hook portion 52 may be locked thereto. As described above, in the photovoltaic power generation panel gantry 80 provided with this safety mechanism, the front side frame 36a and the front column 34a (attachment stay 44a) are not fixed.

  As shown in FIG. 4, for example, one end of the hook portion 52 is a protruding hook-shaped portion that locks the front lateral frame 36a, and the upper surface of the hook-shaped portion is an inclined surface 52a. Further, the bottom surface of the bowl-shaped portion is a locking surface 52b on which the front side horizontal frame 36a is engaged. In addition, it is preferable that the protrusion 52c of the locking surface 52b of the hook-shaped portion is rounded with a predetermined dimension. The hook portion 52 is pivotally supported by a rotation shaft 52d, and rotates about the rotation shaft 52d. Further, an elastic member 54 is installed at the other end of the hook portion 52 as shown in FIG. The elastic member 54 used for the safety mechanism is not particularly limited, and a known elastic member such as a coil spring or a leaf spring can be used. In the example of FIG. 3, the elastic member 54 formed of a tension spring pulls the lower end of the hook portion 52 to the rear side, thereby energizing the hooked portion side with the fulcrum in between, and the front lateral frame 36 a It is the structure which latches.

  A known damper member such as a shock absorber is used as the damper member 56 constituting the safety mechanism, and one end of the damper member 56 is connected to, for example, a vertical frame 46 that fixes the photovoltaic power generation panel 10. Further, the other end of the damper member 56 is connected to a gantry side such as the foundation block 30.

  Next, the operation of the safety mechanism will be described. First, when the wind load applied to the photovoltaic power generation panel 10 is lower than the operating value of the safety mechanism, the photovoltaic power generation panel 10 and the front lateral frame 36a are positioned on the mounting stay 44a by their own weight. At this time, as shown in FIG. 3A, the hook portion 52 urges the front lateral frame 36a toward the mounting stay 44a by the elastic force of the elastic member 54 (locked state).

  Next, when wind blows from the direction of the white arrow in FIG. 3B, an upward force is applied to the photovoltaic power generation panel 10 by this wind load. When the force due to the wind load exceeds the urging force of the elastic member 54 and exceeds the operating value of the safety mechanism, the front lateral frame 36a is lifted as shown in FIG. It rotates and the locked state is released.

  At this time, the rear of the photovoltaic power generation panel 10 is installed on a mounting stay 44b that can be rotated via the rear lateral frame 36b. Therefore, when the latching state of the hook part 52 is released, the front of the photovoltaic power generation panel 10 is in a free state. And as shown in FIG.3 (c), the front of the photovoltaic power generation panel 10 rotates with the attachment stay 44b part as a fulcrum by the wind load applied to the photovoltaic power generation panel 10, and it floats. At this time, the damper member 56 suppresses rapid vertical movement of the photovoltaic power generation panel 10. Then, the rotation of the solar power generation panel 10 opens the front of the solar power generation panel 10 and the solar power generation panel mount 80, and the wind load applied to the solar power generation panel support 80 is reduced. Thereby, even when the strong wind more than assumption blows, the shift | offset | difference and fall of the solar power generation panel stand 80 can be prevented. Moreover, since it is prevented that an excessive wind load is applied to the stand 80 for photovoltaic power generation panels, the weight of the foundation block portion 30 can be reduced.

  Next, when the wind toward the photovoltaic power generation panel 10 weakens, the front of the photovoltaic power generation panel 10 falls due to the weight of the photovoltaic power generation panel 10 and the front side horizontal frame 36a. Also at this time, the damper member 56 suppresses rapid vertical movement of the photovoltaic power generation panel 10.

  When the front side of the photovoltaic power generation panel 10 falls, the front side horizontal frame 36 a comes into contact with the inclined surface 52 a of the hook portion 52. And it further falls, pressing the slope 52a. Thereby, as shown in FIG.3 (d), the hook part 52 rotates to a releasing direction by using a rotating shaft as a fulcrum.

  When the front side horizontal frame 36a falls to the position of the locking surface 52b of the hook part 52, the hook part 52 rotates in the locking direction of the front side horizontal frame 36a by the urging force of the elastic member 54. Thereby, as shown to Fig.3 (a), the front side horizontal frame 36a and the hook part 52 return to a latching state.

  As described above, in the foundation block portion 30 of the photovoltaic power generation panel base 80 according to the present invention, the front foundation block and the rear foundation block are integrated. For this reason, position adjustment with a front side foundation block and a back side foundation block is unnecessary, and installation of the foundation block part 30 can be performed easily. Further, the front pillar portion 32a and the rear pillar portion 32b are formed integrally with the basic block portion 30, and the front pillar 34a and the rear pillar 34b installed on the front pillar portion 32a and the rear pillar portion 32b are higher. It is adjustable. For this reason, even if some unevenness | corrugation and inclination exist in the ground and the basic block part 30 moves up and down somewhat, the position adjustment of the horizontal frames 36a and 36b and the vertical frame 46 can be performed easily. These are particularly effective in a mega solar power plant in which a large number of photovoltaic power generation panels 10 are installed over a wide range.

  Moreover, the basic block portion 30 of the photovoltaic power generation panel gantry 80 according to the present invention has a front pillar portion 32a and a rear pillar portion 32b that rise upward. For this reason, it has a weight larger than that of a conventional foundation block having an equivalent contact area. Thereby, it has the high tolerance with respect to a wind load compared with the conventional foundation block.

  Moreover, in the photovoltaic power generation panel mount 80 provided with the safety mechanism, the space between the photovoltaic power generation panel 10 and the photovoltaic power generation panel support 80 is opened in a strong wind, and the wind load applied to the photovoltaic power generation panel mounting 80 is reduced. Can be reduced. Thereby, even when the strong wind more than assumption blows, the shift | offset | difference and fall of the solar power generation panel stand 80 can be prevented.

  Note that the photovoltaic panel pedestal 80 shown in this example is an example, and each of the front and rear columns 34a and 34b, the front and rear lateral frames 36a and 36b, the vertical frame 46, the photovoltaic panel 10, and the like. The shape, configuration, attachment method, etc. of the members are not limited to this. Further, the shape, configuration, attachment method, and the like of each member such as the hook portion 52, the elastic member 54, and the damper member 56 that constitute the safety mechanism are not limited thereto. Furthermore, the present invention can be modified and implemented without departing from the scope of the present invention.
