Description

  The present invention relates to a solar cell module mount capable of adjusting the gradient of the solar cell module and a solar cell system using the mount.

  In recent years, the use of solar power generation systems has been increasing. In order to withstand the wind pressure load, the installation of the photovoltaic module of the photovoltaic power generation system and its installation frame on the horizontal installation surface of the flat roof of public facilities and factory buildings is based on foundations such as blocks and concrete joined to the roof of the building. This method is often performed by assembling a pedestal frame and attaching a solar cell module to the frame (for example, Patent Document 1).

  Patent Document 1 proposes a support structure in which a vertical rail is installed on a placing foundation, and a support member that supports the solar cell panel by tilting the vertical rail is installed on the vertical rail.

JP 2001-152619 A

  However, in the structure disclosed in the cited document 1, when installing the solar cell panel support structure on the roof of the building, the installation surface is not completely horizontal due to the finishing condition of the roof and the slope of the rain water gradient for flowing rain water. If the horizontal level of the upper surface of multiple mounting foundations is uneven, prepare multiple types of liners, shims, spacers, etc. in order to make the gradient of the solar panel constant. It is necessary to adjust the height between a plurality of pedestal legs by adjusting the height between the bottom of the pedestal legs and the mounting foundation. For this reason, work takes time, the work efficiency at the time of construction worsens, and the construction cost increases.

  In addition, when a liner or the like is simply sandwiched between the bottom of the gantry leg and the foundation, it cannot maintain its function for a long time against wind pressure or seismic force on the upper gantry. Have difficulty. For this reason, it is conceivable to stop the liner or the like on the pedestal by welding, but the welding work has environmental limitations and is difficult to put into practice. In addition, when a shift occurs in the height of the gantry due to an earthquake or secular change, it is difficult to repair such a shift.

  Furthermore, in order to spread dozens of solar cell panels accurately with the same gradient, it is necessary for the frame to form the same inclined surface over the entire installation surface. The gantry mainly comprises a main member and an auxiliary member. In order to form the same inclined surface accurately in a short time and over the entire installation surface as the final purpose, It is necessary to improve the structure and working method of the members.

  The present invention makes it easy to adjust the gradient of the solar cell module even after installation on the installation surface, and can be installed more quickly with a simple configuration and at a low cost. It aims at providing the mount of a battery module, and a solar cell system using the mount.

  One embodiment of the present invention is a solar cell module mount capable of adjusting the gradient of a solar cell module, and is attached to a first end portion on the lower side of the inclined surface of the solar cell module provided to be inclined on the installation surface, A first support member that supports the solar cell module so as to be swingable with respect to the installation surface, and an upper end is connected to a second end that is above the inclined surface of the first end of the solar cell module, and a lower end A second support member connected to a base member provided on the installation surface and supporting the solar cell module with respect to the installation surface, wherein an inclination angle of the solar cell module with respect to the installation surface is changed. And a second support member including a length adjusting means for adjusting the length by a screw shaft, and an inclination of the solar cell module caused by the length adjustment of the second support member by the length adjusting means. A means for allowing movement of the first connection point between the solar cell module and the upper end portion of the second support member due to a change in degree, the second support member at the first connection point, And a allowing means for connecting the solar cell module to each other in at least one of a slidable and swingable manner.

  In another embodiment of the present invention, in the solar cell system using the gantry having the above-described configuration, the gantry and the solar cell module supported by the gantry so as to be capable of adjusting an inclination angle with respect to the installation surface. It is characterized by providing.

  According to the above configuration, even when the installation surface is not completely horizontal and uneven, or when the dimensions of the plurality of foundation members and the horizontal level of the top surface are uneven, the gantry is attached to the installation surface, The solar cell module can be adjusted to the gradient by attaching the solar cell module to the gantry without adjustment and then adjusting the length of the rear support member. Therefore, in order to make the gradient of the solar cell module constant, adjust the height by putting a liner, shim, spacer, etc. between the bottom of the gantry and the base member, and leveling between the gantry There is no need to do work. Therefore, it is possible to improve the work efficiency of mounting and tilt angle adjustment of the gantry and solar cell module, so installation work of the gantry and solar cell system can be done with a smaller number of people, in a shorter construction period and at a lower cost.

The body of the slide bolt 37 is inserted into the long holes 36b, 36b of 36a and the slide bolt through holes 31d, 31d of the pair of left and right side walls 31a, 31a. Thereafter, a washer 39 is fitted into the threaded portion of the slide bolt 37, and a slide bolt nut 38 is screwed in, so that the inclined frame 31 b is attached to the column 31. This is performed for the left and right inclined frames 31b and the columns 31. At this time, the position of the slide bolt nut 38 in the long holes 36b, 36b may be set to substantially the same position for the left and right inclined frames 31b, 31b and the columns 31, 31.

  In the above state, the height of the left side connection point between the left inclined frame 31b and the left column 31 and the right connection point between the right inclined frame 31b and the right column 31 from the installation surface 200 is the installation surface. Are not necessarily in the same position, and are often shifted from each other. That is, in the above state, the solar cell module 2 is distorted, and the gradient is often different between the left and right.

  If the solar cell module 2 has a desired slope and the slope is uniform on the left and right in the state temporarily secured by the above method, the work of temporarily tightening the temporary fastening of the slide bolt nut 38 in that state To complete the installation work on the installation surface 200 of the solar cell system 1.

  When the solar cell module 2 does not have a desired gradient in a state temporarily fixed by the above method, or when the gradient is not uniform on the left and right, the solar cell module 2 Perform gradient adjustment.

When the adjustment of the height of the column 31 is completed, the upper height adjustment nut 34a and the lower height adjustment nut 34b are finally tightened. Finally, the work which finally tightens the loosened slide bolt nut 38 to the slide bolt nut 38 on both the left and right sides is performed, and the installation on the installation surface 200 of the solar cell system 1 and the gradient adjustment work are completed.

  Even after the installation of the solar cell system 1 on the installation surface 200, when the gradient of the solar cell module 2 is shifted due to an earthquake or secular change, the gradient adjustment is performed in the same manner as described above.

  The order of the above methods is not necessarily limited to the description order. It also includes methods that can be performed simultaneously or at different times. For example, the attachment frame 13 may be fixed to the installation surface 200 and then the solar cell module 2 may be attached to the attachment frame 13.

  As described below, the solar cell system 1 according to the first embodiment includes: 1. Shortening the construction period Construction cost reduction (due to construction labor, construction period, transportation cost reduction, etc.) 3. 3. Adjustable after construction. 4. Easy gradient adjustment. 5. Realize simple configuration while maintaining strength. 6. Cost reduction of the device itself (due to material cost reduction, etc.) This is particularly beneficial in terms of a wide range of installation targets (due to load reduction, etc.).

  Even when the installation surface 200 is not completely horizontal and uneven, or when the dimensions of the plurality of rear foundation members 11 and the horizontal level of the upper surface are uneven, the gantry 3 is attached to the installation surface 200 and the horizontal level The solar cell module 2 can be adjusted for the gradient by attaching the solar cell module 2 to the gantry 3 without adjusting, and then adjusting the length of the rear support member 30. Therefore, in order to make the gradient of the solar cell module 2 constant, a liner, shim, spacer or the like is inserted between the bottom surface of the gantry 3 and the rear base member 11 to adjust the height, or between the gantry 3 There is no need to make adjustments for leveling. Therefore, since the work efficiency of mounting and adjusting the inclination angle of the gantry 3 and the solar cell module 2 can be improved, the gantry 3 and the solar cell system 1 can be installed with a smaller number of people, a shorter construction period, and at a lower cost. Work can be done.

  Moreover, since the length adjusting means 4 is provided in the vicinity of the installation surface 200, the adjustment work of the gradient of the solar cell module 2 can be performed safely and efficiently at a low position.

  Moreover, since the rear side support member 30 and the installation surface 200 are firmly fixed via the rear side bolts 33 that are screw shafts, the wind pressure and seismic force applied to the upper frame 3 and the solar cell module 2 are not affected. On the other hand, the function can be maintained for a long time.

  Further, after the installation of the gantry 3 and the solar cell system 1, even when the gantry height is shifted due to an earthquake or secular change, the mounting 3 and the solar cell module 2 are easily attached and the inclination angle is adjusted. be able to.

  Moreover, it is possible to provide a device with a very simple configuration while maintaining the required strength. Therefore, the material cost can be reduced and the assembling work can be simplified. Moreover, since the load of an apparatus can be reduced, the load load to the roof which is the installation surface 200 can be reduced.
