Description

Concrete screw type underground support device of solar power generation apparatus, method of manufacturing the same, and method of installing the same

The present invention relates to an underground support device installed underground to support a solar power generation device.

Recently, due to environmental problems, eco-friendly renewable energy that can be used without environmental pollution by reducing greenhouse gas and fine dust is in the spotlight. Among eco-friendly renewable energies, solar energy has few restrictions on the installation environment and location and has relatively high energy use efficiency, so solar power generation facilities using solar energy are widely distributed.

A photovoltaic power generation facility is a facility that generates electric power using solar energy by installing a solar cell module on a support structure.

Such photovoltaic power generation facilities are installed on a roof, an outer wall of a building, or the like, or are installed on a ground space that can use sunlight, that is, on the ground. When a photovoltaic power generation facility is directly installed on the ground, a panel having a solar cell module (hereinafter also referred to as a 'solar cell panel') is supported through a support structure.

Various methods are used for the support structure depending on the installation terrain or environment. Among them, the screw-type underground support is made to be installed by inserting it while rotating it into the ground in an excavation-free manner in which a screw is installed around a long pipe-type structure. These screw-type underground supports can be used in place of concrete foundations with minimal damage to nature, and have the advantage that they can be constructed regardless of seasons and climates.

On the other hand, Korean Patent No. 10-1190695, Korean Patent No. 10-1160920, etc. also disclose the above-described technology related to the screw-type underground support.

However, the screw-type underground support of the conventional photovoltaic power generation facility including the above prior art has a problem in that the screw is made of an iron plate and installed on the support by a method such as welding.

In other words, when manufacturing screws with iron plates, processing and installation of iron plates to form a constant spiral is not easy, so it costs a lot of money. There is also a problem that the service life may be shortened as it rusts easily.
