Easy-to-fold open and close solar power generation device {EASILLY FOLDING SOLAR PHOTOVOLTAIC STRUCTURE FOR FARMING}

The present invention relates to an open/closed photovoltaic power generation device, and more particularly, to an easily foldable open/closed photovoltaic power generation device capable of easily controlling the amount of insolation by easily moving or folding a photovoltaic panel as needed.

BACKGROUND ART In general, solar power generation is a power generation method that directly converts light energy of the sun into electric energy using a photoelectric converter called a solar cell as one of the power generation technologies by solar energy.

Photovoltaic power generation using solar cells has been in the spotlight as an alternative energy source due to the depletion of petroleum, a fossil fuel, and global warming. is spreading.

The disadvantage of solar energy is that it is important to install a solar panel at a location where sunlight is well received and form a large area where sunlight is incident, so a large amount of sunlight is incident and agricultural land with a large area is required. is inherent

Recently, in order to solve these shortcomings, an open/close type photovoltaic power generation device that can combine photovoltaic power generation and free space utilization has been introduced. The open/close type solar power generation device is to install solar modules in farmland and free space to use the free space and generate solar power at the same time.

The open/close type photovoltaic power generation device is installed to be spaced apart from farmland and free space at sufficient intervals, and generates electricity using only sunlight incident on the front of the photovoltaic panel.

When a solar panel is installed on farmland and free space, the solar panel installed on farmland and free space is irradiated from sunlight to form a shade (shadow) of the solar panel on the ground where plants grow. Plants that grow in the shade There is a problem that it does not grow evenly, and to solve this problem, the sunlight is irradiated to the space or the angle of the solar panel is adjusted by maintaining a certain interval vertically or horizontally so that a certain space is formed between the solar panels. A method for minimizing the shadow formed by the solar panel by rotating it has been proposed.

However, in the conventional photovoltaic power generation device, as in Korean Patent No. 1870374, in order to adjust the angle of the solar panel in order to control the amount of insolation, the solar panel is installed at a predetermined position and then the angle adjusting device is installed to adjust the angle of the panel. Adjusting the angle adjustment device has a problem in that it is not easy to adjust the angle of a plurality of solar panels because the angle of each solar panel must be adjusted individually.

In addition, as a conventional photovoltaic device, a method for adjusting the angle of a photovoltaic panel by installing a wire or a guide bar connected to the frame of the photovoltaic panel has been proposed, but the angle can be adjusted while supporting a plurality of photovoltaic panels with wires. In the case of a long-span photovoltaic device, due to the weight of a plurality of photovoltaic panels, the wire tends to sag in the middle, and this has a problem in that it is not easy to adjust the angle of the photovoltaic panel.
