Description

Support structure for solar power generation modules

[0001] The present invention relates to a support structure, and more particularly, to a support structure for a solar power generation module that reinforces the supporting capacity of the solar power generation module.

[0002] Recently, as interest in environmental pollution has been renewed and people have begun to recognize that environmental problems are directly linked to energy problems, the need for the use of renewable energy has been highlighted.

[0003] Among various renewable energy sources, such as solar energy, wind energy, tidal energy, and solar energy, solar energy is attracting attention as the technology most suited to future growth industries because it generates electricity directly from sunlight using solar cells made of semiconductors, dyes, and polymers. This solar energy can be applied and utilized in a variety of sites, including idle dam sites, farmland, highway rest areas, construction materials, apartment roofs, residential branches, building roofs, sewage treatment plants, abandoned salt farms, landfills, parking lots, coastal landfills, airports, abandoned livestock farms, roads, hilly areas, and mountainous regions.

[0004] However, most power generation facilities for solar energy are currently installed on sites where construction or farming is not possible due to environmental and public complaints, and as a result, installation is expanding to sites with soft ground such as salt farms, reclaimed land, and agricultural areas.

[0005] Meanwhile, when constructing a solar power generation facility, it is important to first build a solid foundation structure on the ground. However, if foundation work is performed on sites like the above, problems such as shaking or collapse due to natural disasters such as typhoons may occur.

[0006] In addition, most of these sites have soil with a high moisture content, which can cause corrosion to progress more quickly than in the soil of a typical site. This makes it difficult to ensure the durability and structural stability of foundation piles over time, and there is also the problem that the soil may become contaminated due to corrosion.

[0007] Accordingly, in the past, construction was carried out by forming a foundation concrete on the ground to respond to shaking, collapse, and corrosion, but this not only increases construction costs and time, but also has the problem of being difficult to apply in practice in sites such as salt fields and farmland because the ground can be contaminated by construction waste such as concrete.

[0008] Therefore, there is a need to develop a foundation pile for ground reinforcement that is simple, applicable to various types of ground, and can guarantee fixing strength, pull-out resistance, and safety.

[0041]

[0042] Hereinafter, with reference to the drawings, a support structure for a solar power generation module according to the present invention will be described.

[0043] FIG. 1 is a schematic diagram illustrating a state in which a solar power generation module is installed using a support structure for a solar power generation module according to one embodiment of the present invention.

[0044] FIG. 2 is a schematic diagram illustrating a support structure for a solar power generation module that supports a solar power generation module according to one embodiment of the present invention.

[0045] FIG. 3 is a perspective view illustrating a support structure for a solar power generation module according to one embodiment of the present invention.

[0046] Figure 4 is an enlarged view of the 'A' portion of the support structure for the solar power generation module of Figure 3.

[0047] Referring to FIGS. 1 to 3, a support structure (1) for a solar power generation module according to one embodiment of the present invention is installed on the ground to support a support frame (20) on which a solar power generation module (10) is installed, and includes a foundation pile (100), a support plate (200), and a support rod (300).

[0048] As illustrated in Fig. 3, the foundation pile (100) has a cylindrical shape and can extend in one direction. The foundation pile (100) can be formed vertically with respect to the ground (30). The foundation pile (100) can have a hollow portion (101) formed in the center so that a support frame (20) can be inserted. The foundation pile (100) is driven into the ground (30), and when the foundation pile (100) is rotated while driven, it digs into the ground (30) and is installed.

[0049] The support plate (200) has a plate shape and can extend radially from one side of the foundation pile (100). The support plate (200) can surround the foundation pile (100). The support plate (200) can extend radially from the periphery of the foundation pile (100).

[0050] The support bar (300) can be fitted into the support plate (200) to support the foundation pile (100). The support bar (300) can be formed in at least three pieces to stably support the foundation pile (100). The support bar (300) can be formed in six pieces as illustrated, but can also be formed in three or more and six or fewer pieces, or six or more pieces.

[0051] As shown in Fig. 4, the support bar (300) is formed to be inclined at a predetermined angle with respect to the longitudinal direction of the foundation pile (100) to support the foundation pile (100), thereby enabling the foundation pile (100) to secure resistance to not only vertical loads but also horizontal loads.

[0052] More specifically, as illustrated in FIG. 4, the support plate (200) may include a circular plate member (210) and a plurality of protruding members (220).

[0053] The circular plate member (210) has a hole corresponding to the hollow portion (101) in the center and can extend radially from the outer periphery of the foundation pile (100).

[0054] The protruding member (220) may protrude from the outer periphery of the circular plate member (210). A portion of the protruding member (220) may be formed in a round shape. A plurality of protruding members (220) may be arranged to be spaced apart from each other at a predetermined interval along the periphery of the circular plate member (210). Each of the plurality of protruding members (220) may include a fitting hole (220h) through which a support bar (300) may be fitted. At least three protruding members (220) may be formed. The number of protruding members (220) may correspond to the number of support bars (300).

[0055] The protruding members (220) are formed in at least three or more and can be arranged to form a regular polygonal shape. For example, the protruding members (220) can be arranged in the shape of a regular triangle, a square, a regular pentagon, a regular hexagon, etc. The protruding members (220) protrude from the circular plate member (210) and are arranged in the shape of a regular polygon, so that the support rods (300) that are fitted into the fitting holes (220h) are also arranged in the shape of a regular polygon, thereby further securing the stability of the support rods (300) that support the foundation pile (100).

[0056] Such a support plate (200) may include an elastic material, and thus may absorb and offset the impact of longitudinal vibration on the ground.

[0057]

[0058] FIG. 5 is a perspective view illustrating a support structure for a solar power generation module according to another embodiment of the present invention, and FIG. 6 is a schematic diagram of a plurality of support rods of the support structure for a solar power generation module of FIG. 5 observed from above.

[0059] The support structure (2) for a solar power generation module according to the present embodiment is identical to the support structure (1) for a solar power generation module described with reference to FIGS. 1 to 4, except for the support rod, and therefore the same reference numbers are used and duplicate descriptions are omitted.

[0060] Referring to Fig. 5, in the support structure (2) for the solar power generation module of the present invention, a plurality of support rods (300a) may be formed to have a predetermined angle with respect to the ground (30). The plurality of support rods (300a) may be arranged in a spiral shape to surround the foundation pile (100) with the foundation pile (100) as the center. In this way, as the plurality of support rods (300a) are arranged in a spiral shape while surrounding the foundation pile (100), the solar module (10) can be stably and firmly supported even under strong wind (wind speed).

[0061] Referring to Fig. 6, a plurality of support rods (300a) can be arranged in a circular shape by being coupled to a support plate (200). At this time, the angle (α) formed by the support rod (300a) and an imaginary tangent line can be formed in a range of 45 to 60 degrees.

[0062] If the angle formed by the tangent line with the support bar (300a) is less than 45 degrees, stress may be generated between the support bar and the support plate (200), which may cause a problem in that the durability of the overall structure of the support structure (2) for the solar power generation module is reduced.

[0063] In contrast, if the angle formed by the support bar (300a) and the tangent line is greater than 60 degrees, when the foundation pile (100) is rotated and driven into the ground (30), the effect of fixing the foundation pile (100) to the ground (30) may be reduced.

[0064] Therefore, it is preferable that the angle (α) formed by the tangent line with the support bar (300a) be formed in the range of 45 to 60 degrees.

[0065]

[0066] FIG. 7 is a perspective view illustrating a support structure for a solar power generation module according to another embodiment of the present invention.

[0067] The support structure (3) for a solar power generation module according to the present embodiment is identical to the support structure (1) for a solar power generation module described with reference to FIGS. 1 to 4, except that it further includes wings, and therefore the same reference numbers are used and redundant descriptions are omitted.

[0068] Referring to Fig. 7, the support structure (3) for the solar power generation module of the present invention may include a plurality of wings (400) spaced apart along the length direction of the foundation pile (100). Each of the plurality of wings has a spiral shape and may be formed on the outer periphery of the foundation pile (100).

[0069] Each of the plurality of wings (400) has a wider diameter than the foundation pile (100), thereby preventing the foundation pile (100) from sinking downwards due to the weight of the solar power generation module (10). In addition, the plurality of wings (400) are attached and installed at regular intervals on the outer periphery of the foundation pile (100), thereby preventing a separation due to friction between the wings (400) and the ground when the foundation pile (100) is inserted into the ground.

[0070] Each of the plurality of wings (400) is formed in a spiral shape, so that mechanical properties such as compressive strength and bending deformation under the same cross-sectional area in the ground and rock can be improved.

[0071] The plurality of wings (400) may have the same size, but as illustrated, they may be formed to increase in size toward the upper layer of the foundation pile (100) where the load is concentrated. That is, the plurality of wings (400) may be provided so that the degree of protrusion from the foundation pile (100) increases as they go upwards of the foundation pile (100), thereby ensuring sufficient support capacity depending on the degree of load concentration on the foundation pile (100).

[0072]

[0073] FIG. 8 is a perspective view illustrating a support structure for a solar power generation module according to another embodiment of the present invention, and FIG. 9 is an enlarged view of part 'B' of the support structure for a solar power generation module of FIG. 7.

[0074] Referring to FIGS. 8 and 9, the support structure (4) for the solar power generation module of the present invention includes a foundation pile (100b), a pair of support plates (200b), a fixing bracket (500), and a plurality of support rods (300b).

[0075] The foundation pile (100b) is installed by being driven into the ground and can be formed in an H shape. The foundation pile (100b) can be configured so that the support frame (20) on which the solar power generation module (10) is installed stands on the foundation pile (100b).

[0076] The foundation pile (100b) may be composed of a pair of first members (110) and a second member (120) connecting the first members (110). The first member (110) may be formed at both ends of the second member (120). The foundation pile (100b) may have an H-shaped cross-section. Between the pair of first members (110) and second members (120), a first guide groove (131) and a second guide groove (132) partitioned by the second member (120) may be formed. The support frame (20) supporting the solar module (10) described above is not shown, but may be connected to the foundation pile by the first guide groove (131) and the second guide groove (132).

[0077] A pair of support plates (200b) may have a plate shape and may have a square plate shape as illustrated. The support plates (200b) may be formed to have a wider width than the outer surface of the first member (110).

[0078] Each of a pair of support plates (200b) may be respectively fixed to a pair of first members (110). A through hole (200bh) may be formed on the upper surface of the support plate (200b) so that a support rod (300b) may be coupled thereto. The number of through holes (200bh) of the support plate (200b) may correspond to the number of support rods (300b). The pair of support plates (200b) may include an elastic material, thereby absorbing and offsetting impact due to longitudinal vibration in the ground.

[0079] The support bar (300b) is fitted into the support plate (200b) and can support the foundation pile (100b). The support bar (300b) can be provided to form a predetermined angle with respect to the longitudinal direction of the foundation pile (100b).

[0080] The fixed bracket (500) can fix the support plate (200b) to the foundation pile (100b). That is, the support plate (200b) can be fixed to the first member (110) by the fixed bracket (500).

[0081] More specifically, the fixed bracket (500) may include a first fixed member (510) and a second fixed member (520), as illustrated in FIG. 8.

[0082] The first fixing member (510) has a plate shape and can be attached to the outer surface of the first member (110). The first fixing member (510) can be formed to have a width greater than the outer surface of the first member (110).

[0083] The second fixing member (520) may be attached to the inner surface of the first member (110) so as to face the first fixing member (510). In this case, the second fixing member (520) may be attached to only a portion of the inner surface of the first member (110). The second fixing member (520) may be formed to surround the side and inner surfaces of the first member (110).

[0084] The second fixing member (520) can be combined with the first fixing member (510). The second fixing member (520) can be screw-connected to the first fixing member (510) using a bolt (530).

[0085] As described above, the fixed bracket (500) composed of the first fixed member (510) and the second fixed member (520) may have a T-shape at both ends, and as a result, the fixing force is improved, and a pair of support plates (200b) can be fixed more firmly to the foundation pile (100b).

[0086]

[0087] FIG. 10 is a perspective view illustrating a support structure for a solar power generation module according to another embodiment of the present invention.

[0088] The support structure (5) for a solar power generation module according to the present embodiment is identical to the support structure (4) for a solar power generation module described with reference to FIGS. 8 and 9, except that it further includes an auxiliary member (600), and therefore the same reference numbers are used and redundant descriptions are omitted.

[0089] Referring to Fig. 10, a support structure (5) for a solar power generation module may include an auxiliary member (600) that connects adjacent support rods (300b). The auxiliary member (600) may include a first auxiliary member (610) and a second auxiliary member (620).

[0090] The first auxiliary member (600) can connect between the support rods (300b) connected to each of a pair of first members (110). The second auxiliary member (600) can connect between the support rods (300b) connected by insertion to either of the pair of first members (110).

[0091] As illustrated, the auxiliary member (600) may be formed in a rod shape to connect the facing support rods (300b). The auxiliary member (600) may be formed integrally with the support rod (300b). Alternatively, although not illustrated, the auxiliary member (600) may be formed in a band shape to bind the facing support rods (300b).

[0092] The auxiliary member (600) is formed as an integral part with the support rods (300b) or the support rods (300b) are connected to each other to form an integral part, thereby ensuring the stability of the structure by eliminating the shear phenomenon even when a horizontal force in the direction of the earth's surface, such as an earthquake, is applied to the support structure (5) for the solar power generation module.

[0093] Although the present invention has been described in detail through specific examples, this is intended to specifically explain the present invention, and the present invention is not limited thereto, and it will be apparent that modifications and improvements can be made by those skilled in the art within the technical spirit of the present invention.

[0094] All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be made clear by the appended claims.
