Fixed bracket for solar module support with enhanced stability {FIXED BRACKET FOR POST OF SOLAR MODULE}

The present invention relates to a fixing bracket for a photovoltaic module post, and more particularly, to maximize the fixing performance of the post by improving the structure of the fixing bracket for fixing the post supporting the photovoltaic module among the support devices of the photovoltaic power generation system. It relates to a fixing bracket for a solar module post with enhanced stability.

The entry into force of the United Nations Framework Convention on Climate Change (UNFCCC) to regulate anthropogenic emission of greenhouse gases to prevent global warming, the rise of oil prices, environmental pollution from nuclear reactor accidents, etc. Accordingly, interest in new and renewable energy to replace existing nuclear and thermal power plants is increasing.

In Korea, a public mandated project that requires the installation of new and renewable energy facilities in facilities with a total floor area of 1,000 m2 or more under the government offices and the Office of Education has been implemented since 2004, and the new and renewable energy has been implemented since 2012. The supply of new and renewable energy and market expansion are expected through the renewable energy portfolio standard (RPS).

Among the aforementioned new and renewable energies, solar power generation systems related to solar energy are not only directly related to the core parts of various industries such as semiconductors, materials, electricity, electronics, architecture, engineering, chemistry, etc., but also closely with the display industry, which is attracting attention recently. As a field, it is essential for securing unlimited future energy and converting industrial structure, and has the importance as a sustainable energy industry.

Such a photovoltaic power generation system is composed of a photovoltaic module, a storage battery, an inverter, and a supporting device, of which the supporting device is a lightweight steel construction using a post. , Steel trust construction, and space frame.

In relation to the Korean Patent Application Publication No. 10-2016-0073844, a solar module support that is installed in a place where a solar power generation system is to be installed and serves to arrange and support the solar module in an appropriate direction has been disclosed, The photovoltaic module support includes a base support extending vertically to the ground of an installation place, an inclined support having a predetermined inclination installed above the base support, and a horizontal support installed on the upper of the inclined support, and It is configured to include a clamp for fixing the solar module to the horizontal support.

Here, the base support (post) is for supporting the photovoltaic module, and is installed vertically according to the height and inclination of the photovoltaic module, and thereafter, the lower end of the base concrete previously constructed by a separate fixing bracket It is fixed bar, the fixing bracket for this purpose is the mainstream of the clamp body is combined in a pair for the purpose of the installation work.

In this regard, through Korean Patent Publication No. 10-2018-0007408, a fixing device for a photovoltaic module base that can firmly fix (bind) the photovoltaic module (solar module) to the base concrete is disclosed. 1 is an exploded perspective view showing a configuration relationship of a fixing device for a photovoltaic power generation module post according to the prior art, and the conventional fixing device for the photovoltaic power generation module post is a post with a photovoltaic power generation module fixed at the top. In the fixing device for a photovoltaic module (hereinafter referred to as "solar module") holding and fixing the lower end of the 910 and screwing to the anchor bolt of the foundation concrete installed on the ground; A base plate 921 having fixing holes through which the anchor bolts penetrate, and extending from one side of the base plate 921 and receiving and fitting a part of one side of the support 910 and both sides connected to the one side It includes a pair of fixing blocks 920 having a fixing bracket 923 in which the fitting groove 922 is formed.

According to the prior art, the fixing brackets 923 of the fixed block 920 in a pair are bound to the foundation concrete while enclosing the support 910 and securing stability by fixing the support 910 It becomes easy to separate and assemble for maintenance.

However, in a state in which the fixing brackets 923 of the fixing block 920 in a pair are wrapped around the lower end of the support 910, the fixing brackets 923 are mutually connected using separate bolts and nuts. When the flow of the photovoltaic module and the post 910 is repeated due to natural phenomena such as strong winds, the bolt and nut are naturally loosened, and the post 910 collapses, the entire solar power generation system. It may lead to a disastrous disintegration.

And, as a means for maintaining the mutual bonding of the fixing brackets 923 and the fixing force of the post 910 accordingly, the bolt and the nut alone can maintain the fixed state of the post 910 under adverse conditions such as strong rain and wind. There have been limitations that make it difficult to maintain.

In the end, it is evident that the key to not only achieving the solidity of the solar module support device but also increasing the convenience of installation work is the fixing bracket for binding (fixing) the pillars to the base concrete. Research and development of the fixed bracket for the solar module holding is urgent.
