Description

Technical Field

[0001] The present invention relates to an agricultural solar power generation structure and an installation method thereof, and more particularly to an agricultural solar power generation structure capable of adjusting the inclination of a solar module during the process of installing the solar module on a support column and an installation method thereof.

Background Art

[0002] Generally, a solar power generation system is installed by vertically standing support columns on the ground, assembling frames of various structures on the support columns, and then installing solar modules on the frames.

[0003] Such a solar module produces electricity using solar energy, and the frame is installed inclined so as to face the direction of solar irradiation in order to maximize the electricity production amount of the solar module.

[0004] Such a solar power generation system has been installed and used on agricultural land in recent years. By concurrently performing solar power generation using solar energy while conducting agriculture, electricity is produced and sold to increase profits, and such agricultural solar power generation tends to expand.

[0005] Such a conventional agricultural solar power generation system is disclosed in Patent Document 1 as an "agriculture-parallel solar power generation system".

[0006] The farm-parallel solar power generation system disclosed in the prior art documents comprises a foundation concrete structure installed at a predetermined depth from the surface of the farmland and projecting outward from the farmland; a column connected to the foundation concrete structure and installed vertically to the farmland, having a predetermined height and formed in the shape of a square pipe; a square tubular horizontal beam intersecting the column and installed horizontally to the farmland; a plurality of purlins formed of square tubular bodies installed at predetermined intervals on the horizontal beam and inclined at a predetermined angle to the surface of the farmland in a direction intersecting the horizontal beam; and solar modules installed on the purlins.

[0007] However, in conventional agrophotovoltaic power generation systems, solar modules must be attached to columns erected vertically on a foundation concrete structure buried in the farmland. This requires towing the solar modules into the air at the site and installing them on the columns in mid-air, which is an extremely difficult process. This not only increases the construction time but also poses a risk of accidents such as falls during aerial work. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Korean Registered Patent Publication No. 10-1842066 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] Therefore, the present invention has been made to solve the problems of the prior art described above, and aims to provide an agricultural solar power generation structure and a method for installing the same, which allows solar modules to be installed in an inclined state by rotating the support columns from the foundation pile, and in which the installation angle of the solar modules can be adjusted during the process to adjust the inclination. [Means for solving the problem]

[0011] Furthermore, the tilt adjustment support base may include a fixed plate that is rotatably mounted on the support column, and a support plate that is fixedly mounted on the fixed plate to receive and support the solar modules.

[0012] Furthermore, the fixing plate may have mounting grooves formed perpendicular to its upper surface, and the mounting grooves may be inclined so that the corner portions are positioned lower on the inside of the fixing plate, and the mounting grooves of the fixing plate may be provided so that the support plate is fitted and fixed in place.

[0013] Furthermore, the support plate may be formed by bending at a right angle, with the corner portion positioned low on the inside of the fixing plate and fixed to the fixing plate in an inclined state, and the side and bottom surfaces of the horizontal bar may be attached to the support plate and joined and fixed in a tightly fitted state.

[0014] Furthermore, a cylinder may be provided between the support column and the tilt adjustment support base to rotate the tilt adjustment support base from the support column.

[0015] Furthermore, in order to achieve the above objective, a method for constructing a solar power generation structure using the agricultural solar power generation structure according to the present invention is characterized by rotating the support column downward in one direction from the support bracket of the foundation pile, temporarily fixing a tilt adjustment support base to the upper end of the support column in a rotatable manner, connecting and fixing the solar module to the tilt adjustment support base, then rotating the tilt adjustment support base from the support column to adjust and fix the tilt of the solar module, erecting the support column from the foundation pile, and then connecting and fixing it to the support bracket.

[0021] Furthermore, the optional terms in the following embodiments are used to distinguish one component from another component, and the components are not limited by those terms.

[0022] Therefore, when explaining the present invention, if a detailed explanation of related known technologies obscures the gist of the present invention, that detailed explanation will be omitted.

[0023] FIGS. 1 to 9 are diagrams showing an agricultural solar power generation structure and its construction method according to the present invention.

[0024] The agricultural solar power generation structure 100 according to the present invention, as shown in FIG. 1, includes a foundation pile 110 driven and buried in the ground, a support column 130 vertically installed on the foundation pile 110, and a solar module 160 installed on the support column 130 to generate electricity using solar energy, that is, to perform power generation.

[0025] Between the foundation pile 110 and the support column 130, a support bracket 120 is provided to guide the support column 130 to rotate in the front-rear or left-right direction (hereinafter referred to as the "left-right direction") from the foundation pile 110.

[0026] As shown in the enlarged view of Figure 1, the support bracket 120 is formed in a "U" shape (when viewed from the side) consisting of multiple side plates that are erected vertically from both sides of the base plate.

[0027] In other words, as shown in Figure 1, the support bracket 120 is provided with front and rear side plates facing each other in the front-rear direction, and is formed to be open in the left-right direction.

[0028] The front and rear side plates of this support bracket 120 have one hinge hole and multiple fixing holes facing each other for bolt fastening. Mounting grooves 120a are formed at the upper ends of both side plates, into which the upper projection 121a of the fixing bracket 121 (described later) is inserted and mounted. An insertion hole 120b is formed in the bottom plate into which the lower projection 121b of the fixing bracket 121 (described later) is inserted.

[0029] Furthermore, fixing brackets 121 are attached to the left and right open sides of the support bracket 120, and the fixing brackets 121 are provided to fix the support column 130 on top of the support bracket 120 in a way that prevents rotation.

[0030] Such a fixing bracket 121 has upper projections 121a on both sides of its upper end that protrude outward and are attached to the mounting grooves 120a of the support bracket 120, and lower projections 121b on its lower end that protrude downward and are inserted into the insertion holes 120b of the support bracket 120. Thus, the fixing bracket 121 is provided by being coupled and fixed in a position on both sides of the support bracket 120.

[0031] Therefore, the support column 130 is provided to rotate left and right by being hinged to the support bracket 120 of the foundation pile 110, and becomes immobile when bolted to the support bracket 120 and the fixing bracket 121 is attached.

[0032] On the other hand, such a support column 130 is equipped with a tilt adjustment support base 140 that can adjust the tilt of the solar module 160. Specifically, the lower part of the tilt adjustment support base 140 is rotatably connected to the upper end of the support column 130, and the solar module 160 is attached and fixed to the upper part.

[0033] Specifically, as shown in Figures 2 and 3, the tilt adjustment support base 140 includes a fixing plate 141 that is rotatably connected to the upper end of the support column 130 and secured by bolt fastening, and a support plate 148 that is installed to be fixed to the upper end of the fixing plate 141 and supports the solar module 160.

[0034] These fixing plates 141 are multiple members arranged in a line at the bottom of the tilt adjustment support base 140, fitted so as to cover the upper end of the support column 130, and provided in a state of external contact with both sides of the support column 130.

[0035] Furthermore, multiple holes are formed in the fixing plate 141. Of these multiple holes, one hole located at the top is provided as a hinge hole 142, and multiple holes located in a row at the bottom are formed as fixing holes 143.

[0036] Furthermore, the upper end of the support column 130 corresponding to the fixing plate 141 is provided with multiple connecting holes corresponding to the hinge hole 142 and fixing hole 143 of the fixing plate 141. Of these connecting holes, the lower connecting holes corresponding to the fixing hole 143 of the fixing plate 141 are shown as an example in Figures 2 and 3 illustrating this embodiment, where two connecting holes are provided. However, the invention is not limited to this, and multiple connecting holes may be arranged in an arc shape.

[0037] By doing so, the tilt adjustment support base 140, which rotates at the upper end of the support column 130, can be rotated and adjusted to various angles, not just the angle specified by the coupling hole in the support column 130. Therefore, the tilt adjustment support base 140 can be used to adjust the tilt of the solar module 160 to various angles.

[0038] Furthermore, although the fixing holes 143 of the fixing plate 141 are shown as circular fixing holes as an example in Figures 2 and 3, they may also be formed as arc-shaped elongated holes 144, as in the other embodiment shown in Figure 4.

[0039] In this case, if an elongated hole 144 is formed in the fixing plate 141, only two connecting holes need to be formed in the lower part of the support column 130 corresponding to the elongated hole 144, and this embodiment of the elongated hole 144 can be said to be the most preferred form for adjusting the angle of the tilt adjustment support base 140.

[0040] By doing so, the tilt adjustment support base 140 can be freely rotated at the upper end of the support column 130, and the rotated tilt adjustment support base 140 can be fixed in any position. Therefore, the tilt adjustment support base 140 can be used to rotate the solar module 160 on the support column 130 to various angles, and the tilt can be adjusted to various angles.

[0041] Furthermore, a mounting groove 145 is formed on the upper surface of the fixing plate 141, into which the support plate 148 is attached and fixed. This mounting groove 145 is formed in such a way that its interior is perpendicular, and includes a bottom support portion 145b formed by the upper surface of the fixing plate 141, and a side support portion 145a formed by a projection extending outward from the bottom support portion 145b.

[0042] In this manner, a support plate 148 of a corresponding shape is fitted and fixed into the mounting groove 145, which consists of a bottom support portion 145b and a side support portion 145a.

[0043] In particular, such a mounting groove 145 is formed in a roughly "V" shape, tilted towards the side receiving portion 148a within an acute angle range with respect to the corner portion, as the right-angle corner portion is located on the inside of the fixing plate 141 and is positioned at the lowest point within the mounting groove 145.

[0044] Furthermore, the support plate 148, which is installed in the mounting groove 145 of the fixing plate 141, is installed so as to protrude long from both sides of the fixing plate 141.

[0045] Such a support plate 148 is formed by bending at a right angle to correspond to the mounting groove 145 and includes a bottom receiving portion 148b that is mounted on the bottom support portion 145b of the mounting groove 145, and a side receiving portion 148a that is in contact with and in close contact with the side support portion 145a of the mounting groove 145.

[0046] Since such a support plate 148 is mounted in a way that it conforms to the mounting groove 145 of the fixing plate 141, the corner portion of the support plate 148 is positioned at the lowest point, and the support plate 148 is also mounted in a state where it is tilted in a roughly "V" shape within an acute angle range along the mounting groove 145 of the fixing plate 141.

[0047] Furthermore, a horizontal bar 150 is mounted on top of the support plate 148. The horizontal bar 150 is a square pipe and is provided with a length that protrudes from both sides of the support plate 148.

[0048] By attaching the horizontal bar 150 in such a state that its lower surface and one side are in contact with the bottom receiving portion 148b and the side receiving portion 148a of the support plate 148, the horizontal bar 150 can be firmly fixed to the support plate 148.

[0049] Furthermore, multiple module frames 161 are arranged side by side at predetermined intervals on such horizontal bars 150 and installed perpendicularly to each other, and one solar module 160 is attached and fixed to each pair of module frames 161.

[0050] On the other hand, as mentioned above, the solar modules 160 can be installed by rotating them from the support column 130 using the tilt adjustment support base 140 to adjust the angle, or tilt, of the solar modules 160.

[0051] In this embodiment, the rotational operation of the solar module 160 was described using a manual type as an example, but it may also be configured as an automatic type using a cylinder 147, as in other embodiments shown in Figure 9.

[0052] In particular, as shown in Figure 9, when the solar module 160, i.e., the tilt adjustment support base 140, is rotated by the cylinder 147, the cylinder 147 is provided with its rear end hinged to the support column 130 and its front end hinged to a hinge bar 146 that protrudes from the rear plate connecting the two fixing plates 141 of the tilt adjustment support base 140.

[0053] In that case, the tilt adjustment support base 140 is supported by the cylinder 147 and arbitrary rotation is prevented, so the fixing hole 143 formed in the tilt adjustment support base 140 and the corresponding coupling hole at the bottom of the support column 130 in the above-described embodiment may be omitted.

[0054] Therefore, as the cylinder 147 extends and retracts, the tilt adjustment support base 140 automatically rotates forward and backward on the support column 130, making it easy to adjust the tilt of the solar module 160 installed on the tilt adjustment support base 140.

[0055] On the other hand, multiple solar modules 160 are installed on horizontal bars 150 that protrude from the support plate 148 of the tilt adjustment support base 140 on both the left and right sides, and the multiple solar modules 160 are installed in a line at predetermined intervals along the longitudinal direction of the horizontal bars 150, as shown in Figure 8.

[0056] Here, between the support column 130 and the horizontal bars 150 protruding from both sides of the support column 130, support rods 170 are provided to support the horizontal bars 150, stably receiving and supporting the solar modules 160 installed on both sides of the horizontal bars 150.

[0057] It is preferable that such a support rod 170 is provided with both ends hinged to the support column 130 and the horizontal bar 150, respectively.

[0058] Furthermore, the construction method for a solar power generation structure using the solar power generation structure according to the present invention comprises the steps of: rotating the support column 130 downward in one direction from the support bracket 120 of the foundation pile 110 and temporarily fixing the tilt adjustment support base 140 to the upper end of the support column 130 so that it can be rotated; connecting and fixing the solar module 160 to the tilt adjustment support base 140, and then rotating the tilt adjustment support base 140 from the support column 130 to adjust and fix the tilt of the solar module 160; and erecting the support column 130 from the foundation pile 110, and then connecting and fixing it to the support bracket 120.

[0059] In other words, the construction method of the present invention consists of a first step of installing a tilt adjustment support base 140 on a support column 130, a second step of installing a solar module 160 on the tilt adjustment support base 140 and adjusting the tilt of the solar module 160, and a third step of erecting and fixing the support column 130 and the solar module 160 on a foundation pile 110.

[0060] Each of these steps will be explained in detail. In the first step, as shown in Figure 5, the support column 130, which is hinged to the support bracket 120 of the foundation pile 110, is rotated downward toward the ground in one direction, and the tilt adjustment support base 140 is rotatably fixed to the upper end of the support column 130 that has been rotated toward the ground.

[0061] Here, the tilt adjustment support base 140 is hinged to the support column 130 by the hinge hole 142, so that it can rotate freely from the support column 130.

[0062] In this state, as in the other embodiment shown in Figure 9, if the hinge bar 146 and support column 130 of the tilt adjustment support base 140 are connected to the cylinder 147, the tilt adjustment support base 140 is restrained by the cylinder 147, thereby preventing arbitrary rotation of the tilt adjustment support base 140.

[0063] In the second step, as shown in Figure 6, horizontal bars 150 are installed on the support plate 148 of the tilt adjustment support base 140 so as to protrude further on both sides, and a plurality of module frames 161 are installed in pairs on the horizontal bars 150, and solar modules 160 are attached to the plurality of module frames 161 and joined together and fixed, and then the tilt adjustment support base 140 is rotated away from the support column 130 to adjust the tilt of the solar modules 160, and then the tilt adjustment support base 140 is fixed to the support column 130 by bolting it through the fixing holes 143, or, as shown in Figure 9, the tilt adjustment support base 140 is automatically fixed by stopping the operation of the cylinder 147.

[0064] In other words, in the case of a type where the tilt of the solar module 160 is adjusted manually, the tilt adjustment support base 140 is connected and fixed to the support column 130 by bolting the fixing holes 143 or elongated holes 144 of the support base 140, while in the case of a type where the tilt of the solar module 160 is adjusted automatically, it is fixed by the cylinder 147.

[0065] In the third step, as shown in Figure 7, the support column 130 is erected from the foundation pile 110, then the erected support column 130 is bolted to the support bracket 120, fixing brackets 121 are installed on both sides of the support bracket 120 on which the support column 130 rotates, and then the fixing brackets 121 are bolted to the support column 130. In this way, the support column 130 is restrained and fixed in a non-rotatable state, covered by the support bracket 120 and the fixing brackets 121. [Industrial applicability]

[0066] Therefore, the agricultural solar power generation structure 100 of the present invention can be easily installed by rotating the support columns 130 from the foundation piles 110 to tilt them, then sequentially installing the tilt adjustment support bases 140 and solar modules 160, rotating the tilt adjustment support bases 140 to adjust the tilt of the solar modules 160 from the support columns 130, and then erecting and fixing the support columns 130. This improves constructability and prevents accidents caused by aerial work.

[0067] Although the present invention has been described in detail above with reference to specific embodiments, these are merely for illustrative purposes and the present invention is not limited thereto. It goes without saying that modifications and improvements can be made within the technical concept of the present invention by those with ordinary skill in the art.

[0068] Any mere modification or alteration of the present invention is included within the scope of the present invention, and the specific scope of protection of the present invention is made clearer by the claims. [Explanation of symbols]
