Description

Multipurpose (including farming in parallel) solar PV system and construction method thereof

The present invention relates to a 'multi-purpose solar power system for parallel farming, etc.' (hereinafter, abbreviated as 'multi-purpose solar power system') to which other uses other than the purpose of photovoltaic power can be added. Specifically, photovoltaic power generation This is to facilitate the implementation of a 'multi-purpose solar system' by mounting and fixing the solar power panel on the upper part of the structure so that the lower part of the panel can be used for original or other purposes such as farming, rivers, or landscaping. The multi-purpose photovoltaic system is a photovoltaic power generation system installed in a so-called 'Hanging type structure'.

In addition, the present invention is a 'multipurpose solar system' that can add irrigation or pesticide spraying facilities for farming, planting of vines for landscaping, or separate lighting, power lines and communication lines to the structure of the multi-purpose solar system itself. is about

The photovoltaic power generation system is a power generation system that converts solar energy incident on a photovoltaic panel installed on the ground surface into electricity and harvests it. Since the amount of solar energy incident on the earth's surface is expressed as horizontal insolation, it is natural that the lower part of the photovoltaic panel is reduced by the amount of insolation incident thereon. In the case of an agricultural solar power system, it is necessary to arrange a photovoltaic panel in consideration of a decrease in crop yield due to a decrease in horizontal solar insolation.

A photovoltaic power generation system can be built with optimum efficiency on sites such as sidewalks, parking lots, and rivers that do not absolutely require 100% of the amount of insolation that is incident on the lower part of the photovoltaic panel. Nevertheless, it is desirable to consider the environment-friendly landscaping that satisfies the original use of parking and drainage other than the purpose of photovoltaic power generation.

Multi-purpose solar systems such as parallel farming are also constructed by installing solar power panels on the roofs of buildings that have primary uses such as warehouses, mushroom growers, insect farms, fish farms, and livestock houses. This is to provide a technical idea for adding a secondary use of solar power to the existing open land. To this end, a photovoltaic power generation system is implemented by installing a structure on the open land and placing a photovoltaic panel on the structure to have a certain shading rate.

In general, in order to utilize the space under the solar power panel for various purposes, a duck-type structure consisting of a high column and a long beam or a very long girder (hereinafter simply referred to as a 'girder') is required. is required In the case of an agricultural photovoltaic power generation system, a distance between the pillars is required that does not interfere with the operation of agricultural machinery. In the case of installing a photovoltaic power generation system on a river site, it is necessary to ensure that not only do not disturb the flow of water but also the safety of the photovoltaic power generation system facilities by locating the pillars on the riverbank as much as possible.

The distribution of solar energy is recommended at the national level, and various R&D and support policies are being implemented to promote it. In order to secure a site for photovoltaic power generation, an agricultural type is considered preferentially as a multi-purpose photovoltaic system. In particular, since the rice farming site has a flat topography, it is possible to easily install a photovoltaic power generation system, and it is possible to generate electricity through solar power all year round without much reduction in yield.

Since the solar energy resource is the same anywhere on the site that is not shaded by the surrounding terrain or structures, it can be used appropriately. If a solar power panel is installed on a dead space such as a river, road, or park in a city or village, it can utilize solar energy while hardly impairing the use of the original site or improving one aspect. For example, in the case of a park, if it is installed on a walkway, a useful shading effect can be expected, so it can be used throughout the summer.

Existing agricultural solar power generation systems are published in the following patent documents. In order to effectively collect solar energy, they control the solar power generation panel to face or track the sun according to the direction of the substructure, so the installation is limited according to the layout and direction of the land. In order to solve such a problem, a photovoltaic power generation system in which a photovoltaic panel is fixed on a single pole is proposed, but this also causes another problem in maintaining structural stability.

Since the design lifespan of a photovoltaic power generation system is at least 20 years, it is necessary to take this into account, not only the efficiency of solar energy collection, but also the disaster resistance of the building structure due to meteorological disasters such as heavy snow and strong winds. In addition to the disaster-resistant standards for horticultural and special crop facilities (Ministry of Agriculture, Food and Rural Affairs Notice No. 2014-78, July 24, 2014), the Ministry of Agriculture, Food and Rural Affairs, specifications, blueprints and specifications for disaster-resistant standard facilities for plastic houses, simple mushroom growers, and ginseng facilities is posted on the website of the Rural Development Administration (http://www.rda.go.kr). It is self-evident that the 'multi-purpose solar system' proposed in this invention should be designed and constructed in consideration of the disaster-resistant standard.

The present invention was invented to improve the above problems, and one of the problems to be solved through this is multipurpose for secondary use of solar power generation on land that is being used for primary purposes such as cultivation for agriculture and horticulture It is an effective implementation of the solar system.

Another object of the present invention is to minimize the hindrance to the utility of the primary use of land without restriction of location (related to directionality and flatness), and to maximize the efficiency of collecting solar energy, which is a secondary use.

Another object of the present invention is to have a wide gap between the columns and a high height of the columns themselves so that a sufficient working space is secured in the lower part so that the land can be used without unreasonableness for the primary purpose of the land.

Another object of the present invention is to have a long-term (20 years or more) disaster resistance against meteorological disasters such as heavy snow and strong winds for facilities including photovoltaic panels installed on open natural land.

Another object of the present invention is to contribute to the spread of solar energy by enabling the installation of a solar power generation system on idle land (parking lot, small park, river, sidewalk, road, crossing) that does not require 100% of sunlight. .

Another object of the present invention is to install a power line and/or communication line in or below a structure in which a photovoltaic panel is installed, lighting, irrigation and pesticide/liquid fertilizer spraying equipment and/or harmful tidal control network in the lower part of the girder or a certain part It is possible to further add tertiary uses such as attachment of plants or landscaping using creepers.

Another object of the present invention is to maintain a certain standard and quality by enabling prefabrication of major components in a factory.

Another object of the present invention is to easily assemble and construct a 'multi-purpose solar energy system' on site.

In order to achieve the above object, the present invention is to fix at least two pillars, such as a commercial product, a utility pole, on the land and horizontally fix a long girder or beam on the top of the pillar, the girder itself Or a photovoltaic panel with an appropriate inclination angle in an appropriate direction (a value determined near the north-facing inclination angle of the south-facing in the case of the Northern Hemisphere or the north-facing south-latitude inclination in the case of the Southern Hemisphere, hereinafter referred to as the 'appropriate inclination angle') To install a PV support body or PV rack.

The girder is composed of a pair of upper chords (or lower chords) and one lower chord (or upper chords) so that the cross section has an inverted triangle (or general triangle) shape. The PV rack (PV rack), which is integrated by attaching photovoltaic panels to the girder itself, becomes a long girder and can be fixed on the beams on both sides. Of course, the PV rack can be mounted and fixed on the inverted triangular girder installed as a load-bearing structure.

In the case of a girder having an inverted triangular cross-section, the lower chord is also composed of a pair to make the cross-section a rectangle, or a pair of middle chords are added between a pair of upper chords and one lower chord to cut the cross-section. You can also do it with rectangles. Of course, it can be expanded by adding a plurality of middle chords between the upper and lower chords. The girder has a pair of upper chords positioned essentially horizontally. A girder having a general triangular cross section constituting a PV rack has a pair of horizontally positioned lower chords and one parallel upper chord thereon, so that the upper chord and one lower chord have an appropriate inclination angle.

Between the two upper chords of the girder having the inverted triangular cross section, a top lateral strut is attached as a straight compression web member to form a trapezoid, and a PV support including a photovoltaic panel at regular intervals thereon ( PV support body) is fixed to form a photovoltaic power generation system.

The PV support includes an inclined support member, and a photovoltaic panel is fixed on the inclined support member, and the inclined support member is on the PV Pedestal plate in the northern hemisphere to the south (or from the southern hemisphere to the north). The solar panel is installed at an 'appropriate angle of inclination' according to the latitude (north latitude in the northern hemisphere and southern latitude in the southern hemisphere) of the place where the inclined material is located.

The inclined support material is two line segments forming an acute angle, and the support part including the support part and the inclined part is seated in an appropriate direction on the PV support plate, and the solar power generation panel is attached to the inclined part thereon.

Fixed by adding a Diagonal member as a Compression Web member between the upper and lower chords (including middle chords, if any, and only the upper chords and lower chords are referred to below until there is a need to specifically discuss them) It forms a light and long girder in the form of (welded) lattice girder or truss girder. The truss type structure assembles several straight members into a continuous triangular structure within one plane to form a structure made of frictionless hinges at the nodes of all members. compression), and in the lattice type structure, the nodes of each member are fixed, so that the moment acts in addition to the axial force.

In addition, it is also possible to form a light and long girder in the form of a box girder by attaching a sheet material perforated in a honeycomb shape between the upper chord and the lower chord by attaching a honeycomb girder or a sheet material without perforation.

The upper and lower chords themselves include, in addition to round tubes, rectangular tubes as well as section steels of various cross-sectional shapes (a, c, I, H, T), flat steel, or mixed materials, and the material of the material is It optionally includes ordinary steel, special steel, non-ferrous, alloy, plastic, wood or other mixed materials.

The girder is fixed by connecting the finishing materials at both ends to the (pillar-girder) connecting means fixed to the two columns. By replacing the members at both ends among the dead material, which is a plurality of samurai of the girder, with a reinforced end member, the reinforcing end member has an inclination angle and thickness different from the dead material to fix between the upper and lower chords of both ends of the girder Form the harness of the girder.

The girder naturally causes bending or deflection according to the weight of the PV support including the photovoltaic panel, so in consideration of this, the upper and lower chords are pre-bent in opposite directions during pre-production, and then the lattice is fixed between them with a saphenous material. Alternatively, a truss shape, honeycomb or general plate is attached to produce a honeycomb or box shape.

The girder optionally further includes a (length-tension) control means (Chord tension control means) capable of adjusting the length and tension at one of both ends of the upper chord and the lower chord.

In principle, the girder is installed horizontally between the two columns, but if there is a difference in the elevation of the applied land and the difference is to be reflected as it is, the girder is installed with a slight inclination angle between the two columns and the inclination angle on the upper chord By varying the height of the inclined support material fixed on the PV pedestal plate fixed to the PV panel, the photovoltaic panel is fixed to have an appropriate inclination angle.

A (girder-girder) cross-connection means is included in the middle part of the girder installed between the two columns, and a node is formed by fixing another girder to this connecting means, and including the column, the node is used as a vertex. A unit rectangular structure is formed, and the rectangular unit rectangular structure connects the vertices with a diagonal-tensile member further comprising a tension member, and the diagonal-tensile member connects between the lower portion of the node and the upper end of the column, and , The diagonal-diagonal tension control means for adjusting the tension at one end of the tension member (Diagonal tension control means) further comprises.

A power line and/or communication line is installed in a space of a triangular, rectangular or pentagonal shape formed inside the longitudinal section of the girder, or lighting, irrigation and pesticide spraying facilities and/or harmful tidal control net are added to the lower part of the girder or a certain part. Alternatively, the creeper plant transplanted to the land is attracted to the lower part of the girder or to a certain part to enable landscaping.

The girder is designed in accordance with the disaster-proof design standards and road transport regulations, manufactured in the form of a module at the factory before construction, transported, and assembled on site to complete the 'multi-purpose solar system'.

According to the present invention having the configuration as described above, the following effects can be achieved.

The 'multi-purpose solar system' is easy to secure installation space, so the supply of solar energy that is encouraged and required at the national level can be expanded.

By forming light and long girders in the shape of lattice, truss, honeycomb, and box, it is possible to increase the spacing between the pillars fixed to the land, so that sufficient working space at the bottom can be secured. be able to

By applying a long girder that can widen the distance between high columns and columns, problems caused by using the original land used for primary purposes such as farming, parking, sidewalks, and rivers as it is will be minimized. In the case of arable land for farming, it is essential to secure sufficient space under the 'multi-purpose solar system' as a considerable size of agricultural machinery is operated.

Since the PV support is fixed and installed on the girder to have an appropriate inclination angle, it is possible to effectively implement a photovoltaic power generation system by minimizing the influence of the shape or direction of the land for primary use. Even on uneven terrain, solar power generation is possible efficiently while resolving location restrictions by installing photovoltaic panels at an appropriate angle of inclination.

When a commercial standard product, a utility pole, is adopted as a pillar to support a long girder, it is a structurally verified product, and thus high quality can be maintained. As a result, it is possible to construct a 'multi-purpose solar system' cost-effectively.

The structural safety of the long girder is easily secured through the end member, reinforced end member, and (length-tension) control means applied to both ends of the girder.

By connecting the diagonal of the rectangular structure with the internal node of the (girder-girder) cross connection means inside the girder as the vertex with a diagonal-diagonal tension member, By maintaining the tension between the vertices as a diagonal tension control means, it is possible to easily secure the disaster-resistant structural safety of the 'multi-purpose solar system'.

By installing power lines and/or communication lines in the interior space of the longitudinal section of the girder, adding lighting, irrigation and pesticide/liquid fertilizer spraying facilities and/or harmful tidal control nets to the outside, or selectively applying landscaping using creepers, etc. The utilization of the 'multi-purpose solar system' can be maximized.

The main components according to the present invention are manufactured and verified to meet the inherent disaster design standards in a factory where quality control is possible in advance, and then are transported to the site and go through the assembly and installation process. It is possible to secure the disaster-resistant structural safety of the 'multi-purpose solar system' without doing so.

In addition, the main components according to the present invention are planned and designed in consideration of the construction conditions and road transport regulations at the site and can be manufactured for each module, so that the components transported to the site can be easily carried out with the help of minimal construction equipment or manpower at the site. It can be easily assembled, and a 'multi-purpose solar system' can be installed systematically and at low cost.
