Description

TECHNICAL FIELD The present invention relates to a mount for installing a solar panel.

In recent years, abnormal weather on a global scale has become a problem, and the cause of this abnormal weather is considered to be a global warming phenomenon. Therefore, in place of petroleum, which is the main cause of global warming and has a large environmental load, new energy that has a low environmental load and is friendly to the earth is attracting attention. Among them, one of the most practically used is solar power generation.

Generally, large-scale photovoltaic power generation employs a method in which photovoltaic panels are installed on a frame. There is still much demand for installing solar panels, and there is also demand for installation not only on flat land but also on sloped land. For example, there may be demand for installation on sloped land developed as a golf course. The undulations mainly on the golf course are called "undulations", and there are various undulations depending on the location. There is a demand for a solar panel installation technique that can cope with such undulating installation locations.

Although the material cost is higher than that of steel materials, the light weight improves transportability and workability, and the total cost of installing the frame is on a downward trend.

<Connection Relationship Between Second Rail 20 and Solar Panel 2 (Module 2M)>
FIG. 9 is a diagram showing the connection relationship between the second rail 20 (longitudinal rail) and the solar panel 2 (module 2M). Since the surface of the solar panel 2 is made of tempered glass, it is relatively resistant to impact, but it is very weak to impact from the back side. The main causes of damage are the following three factors (see https://earthcom-eco.jp/column/investment/cause-damage-solarpanel).
As long as the solar panel 2 is used outdoors, damage to the solar panel 2 cannot be completely prevented, so when the panel fails, it must be replaced.

(1) External factors Cracks and cracks in panels caused by flying objects Local pressure concentration: heavy snowfall, strong winds caused by typhoons Distortion due to twisting and bending: earthquakes, etc. Damage from the back side: growth of weeds, bamboo, and bamboo grass・Long-term stains on the surface: Due to bird droppings, fallen leaves, etc., sunlight cannot reach that part and power generation cannot be performed. In the worst case, it may cause a fire.
(2) Internal factors ・Cases in which moisture enters and accumulates in the solar panel 2, causing discoloration and turbidity (leading to a decrease in power generation)
(3) Troubles during transportation and construction Microcracks occur due to being struck by tools or being hit during transportation (leading to a decrease in power generation).

On the other hand, the actual situation of the manufacturer of the solar panel 2 is that they develop a new solar panel 2 with high power generation efficiency almost every year, and they are discontinued in several years without securing the inventory of the old product. . Therefore, when trying to replace the solar panel 2 when it is damaged, the manufacturer does not have the stock, and there is no other choice but to use a substitute product from another company. However, the problem in that case is that the position of the connection fitting for connecting to the second rail 20 (longitudinal rail) and the size of the solar panel 2 itself are different. The gantry 1 is also required to cope with these problems.

The upper half of FIG. 9 is an example of installation using solar panel 2 (module 2МA) manufactured by Company A, and the lower half is solar panel manufactured by Company B, another company, because Company A does not have inventory for the above reasons. This is an example of installation using panel 2 (module 2МB).

According to the configuration of this embodiment, the second rail 20 (longitudinal rail) connected to the solar panel 2 (module 2M) interlocks with the connection fixing member (slope pedestal 7A, rolling fixing bracket 7B). Since the first rail 10 (horizontal rail) can be slid in the longitudinal direction, even if the position of the connection fitting of the solar panel 2 (module 2М) changes, the size of the solar panel 2 (module 2М) does not change. However, as shown in FIG. 9, it is possible to respond flexibly.

The gantry 1 of this embodiment has the following features.
(1) A frame for installing the solar panel 2, which is a foundation pile 3 fixed to the foundation of the ground at the installation site, one or more diagonal struts 4 arranged on the side of the foundation pile 3, A connection member 5 (diagonal support fixing bracket) that fixes one end of the oblique support 4 to the foundation pile 3, a first rail 10 (horizontal rail) provided substantially parallel to the ground, and each oblique support 4 Correspondingly, an oblique strut fixing member 6 (H connection fitting) arranged on the first rail 10 is provided, and the oblique strut fixing member 6 is attached slidably in the longitudinal direction of the first rail 10, It is characterized in that it is connected to the corresponding oblique support fixing member 6 within the movable range of the other end of each oblique support 4 .
