Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting base for a solar cell module which receives sunlight and converts its energy into electric power.

[0002]

2. Description of the Related Art There is a photovoltaic power generation system that receives sunlight by a solar cell module and converts sunlight energy into electric power. The solar cell module is installed on the ground or on a flat roof. When the solar cell module is installed, a stand is required to keep the solar cell module safe against natural external forces such as wind load, snow load, and seismic load.

[0003] Of the load applied to the solar cell module,
Particularly, the wind load changes according to the installation area and the height of the installation surface, and also changes according to the module position even in the same installation place. When designing the mounting frame,
Considering the most severe load conditions including the change in wind load as described above, a standard design that can withstand the load conditions is made.

[0004]

As described above, the mounting frame of the standard design in consideration of the strictest load conditions has a problem in that the number of constituent members increases, the construction cost rises, and the construction period is prolonged. . The present invention has been made in view of the above circumstances, and aims to reduce the amount of components, reduce the construction cost, shorten the construction period, etc., while achieving a severe wind load,
An object of the present invention is to provide a standardized mounting base for a solar cell module that can sufficiently withstand a snow load, an earthquake load, and the like.

[0005]

Means for Solving the Problems First Invention (Claim 1)
The mounting base of the solar cell module is a plurality of blocks, a mounting body that supports the solar cell module made of a plurality of frame materials provided on these blocks,
Is provided.

According to a second aspect of the present invention, there is provided a mounting base for a solar cell module according to the first aspect, wherein each block is made of concrete, and the solar cell module includes a plurality of solar cell panels arranged. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, two concrete blocks 1 having a thin brick shape and two concrete blocks 2 having a thick brick shape are provided.
It is provided at each corner of the square.

Both ends of an L-shaped frame member 3 are fixed to the upper surface of each block 1 by screws or bolts, and both end portions of the frame member 3 are fixed to the upper surface of each block 2 by screws or bolts.

One end of an L-shaped frame member 5 is fixed to the frame member 3 on the upper surface of one block 1 via a connecting member 4 with screws or bolts, and the other end of the frame member 5 is connected to one block 2. Screws or bolts are fixed to the frame member 3 on the upper surface via the connecting tool 4.

One end of the frame member 5 is also fixed to the frame member 3 on the upper surface of the other block 1 via a connecting member 4 with screws or bolts.
Is screwed or bolted to the frame member 3 on the upper surface of the other block 2 via the connecting member 4.

The frame body is constituted by the frame members 3 and 5. The gantry body has a simple structure of assembling a plurality of frame members, but has sufficient strength to withstand a snow load, an earthquake load, and the like. Installed (placed) on a flat roof.

Each of the blocks 1 and 2 serving as a pedestal of the gantry body
Is to provide the gantry body with a low center-of-gravity load and to function as a counterweight against the wind load. When the wind load is large, another block 1 is added between each block 1 or each block 2 It is possible to add another block 2 between each other.

Then, as shown in FIG. 2, the solar cell module 10 is mounted on each frame member 5 of the gantry body. When installing, the thickness of block 1 and block 2
Are different from each other, the solar cell module 10 is supported in an inclined state so as to face the sun.

The solar cell module 10 has a plurality of solar cell panels arranged in rows and columns, receives sunlight, and converts its energy into electric power. As described above, a gantry body having a simple configuration in which a plurality of frame members are assembled on a plurality of blocks is employed, and the solar cell module 10 is mounted on the gantry body.
A standardized mounting base that can withstand severe wind loads, snow loads, seismic loads, etc., while reducing the amount of materials, reducing construction costs, shortening the construction period, etc. Can be obtained. Moreover,
The number of blocks used can be easily adjusted according to the magnitude of the wind load, which is convenient.

Although the concrete block is used in the above embodiment, the block is not limited to concrete but may be made of another material as long as it has its own weight and functions as a counterweight against wind load. May be. In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.

[0016]

As described above, according to the present invention, there are provided a plurality of blocks and a gantry main body which is composed of a plurality of frame members provided on these blocks and supports the solar cell module. It is possible to provide a standardized mounting stand for a solar cell module that can sufficiently withstand severe wind loads, snow loads, earthquake loads, and the like while achieving a reduction in the amount of components, a reduction in construction costs, a shortened construction period, and the like.
