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 solar cell module installation mount includes a mount main body made of a plurality of frame members and supporting the solar cell module, and a plurality of blocks detachably provided at the bottom of the mount main body.

According to a second aspect of the present invention, there is provided a solar cell module mounting base according to the first aspect, wherein the solar cell module is formed by arranging a plurality of solar cell panels, and the base body is a solar cell module. Are supported in an inclined state, and each block is made of concrete.

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, a pair of longer L-shaped frame members 1 and a pair of shorter L-shaped frame members 2 are assembled in a rectangular shape to form a lower frame.
Each frame member 1 is arranged such that the inner periphery faces upward and outside the frame, and each frame member 2 is arranged such that the inner periphery faces upward and inside the frame.

At the two corners at both ends in the longitudinal direction of the lower frame, a short L
The frame members 3 each having a character shape are vertically erected, and the longer frame members 4 each having a long L shape are erected at the remaining two corners.

An upper frame is formed by assembling a pair of longer L-shaped frame members 5 and a pair of shorter L-shaped frame members 6 in a rectangular shape. Each frame member 5 is arranged such that the inner periphery faces downward and outside the frame, and each frame member 6 is arranged such that the inner periphery faces downward and inside the frame. This upper frame is attached to the upper end of each frame member 3 and each frame member 4.

The frame members are connected by screws or bolts, and the connection forms a tower-like base body. The gantry body is installed (placed) on the ground or on a flat roof.

The gantry body has a sufficient strength to withstand a snow load, an earthquake load, etc., while having a simple structure in which only a plurality of frame members are assembled. On the bottom of the gantry body, the inner circumference of each frame material 2 is used as a mounting surface,
A plurality of concrete and columnar blocks (also referred to as concrete curb blocks) 7 are detachably provided as counterweights against wind loads.

Each block 7 has substantially the same length as the frame material 1, and is inserted into the gantry body sequentially between the respective frame materials by an operator's manual operation, and placed side by side in the lower frame. You. By this mounting, a low center-of-gravity load is applied to the gantry body, and the gantry body becomes strong enough to withstand the wind load. Also, depending on the magnitude of the wind load, the block 7
Can be easily adjusted.

Furthermore, since each block 7 is housed in the lower frame with its own weight, it does not roll out of the gantry body and is safe. Then, as shown in FIG. 2, the solar cell module 10 is attached to the upper frame (frame members 5, 6) of the gantry body. With this attachment, 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, the gantry main body is configured by assembling a plurality of frame materials, and the simple configuration in which the plurality of blocks 7 are detachably provided on the gantry main body reduces the number of members, the construction cost, and the like. It is possible to obtain a standardized mounting base that can sufficiently withstand severe wind loads, snow loads, seismic loads, etc. while shortening the construction period.

Although the concrete block 7 is used in the above embodiment, the concrete block 7 is not limited to concrete but may be made of any other material as long as it has its own weight and functions as a counterweight against wind load. May be adopted.
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 is provided a gantry body composed of a plurality of frame members and supporting a solar cell module, and a plurality of blocks detachably provided on the bottom of the gantry body. Therefore, a standardized mounting base for solar cell modules that can fully withstand severe wind loads, snow loads, earthquake loads, etc. Can be provided.
