Description

[Technical Field]

[0001] The present invention relates to a foundation structure for an agricultural solar power generation structure, and more specifically to a foundation structure for an agricultural solar power generation structure that simplifies the number of parts that make up the foundation structure and reduces the labor required to assemble the solar power generation structure. [Background technology]

[0002] Generally, a solar power generation system is constructed by installing a support, assembling a frame of various structures on the support, and then installing a solar cell module on the frame. The solar cell module generates electricity using solar energy, and the frame is installed at an angle so that it faces the direction of sunlight to maximize the amount of power generated by the solar cell module.

[0003] Recently, such solar power generation systems have been installed on farmland, and farmers are generating electricity using solar energy in parallel with farm work, selling the generated electricity to earn revenue. This type of agricultural solar power generation is on the rise.

[0004] As an example of such a solar power generation system, the applicant of the present application has proposed an "agricultural solar power generation structure" in Patent Document 1.

[0005] Patent Document 1 discloses a joint device for a photovoltaic power generation structure, which includes a foundation pile that is driven into the ground, a support pole on which a photovoltaic power generation structure is erected, and a connecting piece and a fixing piece that connect the support pole and the foundation pile and fix the rotating support pole in an erected state, and the connecting piece includes a first support piece that is rotatably connected to the support pole on the foundation pile and fixes the support pole in an erected state, and a second support piece that extends from the first support piece and is joined to the foundation pile, and the first support piece has a plurality of elongated holes that are joined to the support pole, and includes a support plate to which the fixing piece is hooked, and a second support piece that extends from the support plate and fixes the base pile. The second support piece comprises a first cover plate that encases the outer peripheral surface of the foundation pile and a second cover plate that extends from both sides of the first cover plate with a step, the first cover plate being extended outward from the second cover plate with a step so that it has a larger diameter than the second cover plate, and is arranged so that it can rotate and adjust its position while accommodating a joining protrusion that protrudes outward from the foundation pile, and the second cover plate is formed with a reinforcing rib that is joined to the first support piece.

[0006] In Patent Document 1, two support pieces of a connecting piece are connected to the upper end of a foundation pile buried in the ground in a state where they face each other and wrap around the foundation pile, and in this state, a support pillar is inserted between the two support pieces of the connecting piece and fastened in an upright position, thereby erecting the support pillar on the foundation pile.

[0007] However, in conventional solar power generation systems, in order to install a support pillar on a foundation pile, it is necessary to install a connecting piece at the upper end of the foundation pile.At that time, the connecting piece is made up of multiple support pieces, and installation of the connecting piece is completed by fastening and fixing two support pieces facing each other on both sides of the upper end of the foundation pile.

[0008] In this way, the foundation structure, including the foundation piles and connecting pieces for installing the supports, is made up of an unnecessary number of parts, which not only increases the number of work steps, reduces workability, extends the assembly and installation period, but also increases the installation costs. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Korean Patent Registration No. 10-2457075 Summary of the Invention [Problem to be solved by the invention]

[0010] Therefore, the present invention has been devised to solve the problems of the prior art as described above, and its object is to provide a foundation structure for an agricultural solar power generation structure that can shorten the labor hours and installation time of the solar power generation structure by simplifying the components that make up the foundation structure for installing the support poles. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the foundation structure of an agricultural solar power generation structure of the present invention is a foundation structure of a solar power generation structure for installing supports for the solar power generation structure, and is characterized in that it is arranged opposite to foundation piles buried in the ground, and multiple support piece portions are each integrally formed with the foundation piles.

[0012] The support piece portion of the foundation structure is further provided with a receiving piece portion that is bent from the support piece portion toward the foundation pile and fixed to the foundation pile, and one end of the support piece portion that is connected to the receiving piece portion is formed with a bent portion that is concave and bent so as to protrude outward, so that the support piece portion that is screwed to the support pillar is provided in a state of face-to-face contact with the support pillar.

[0013] Furthermore, the substructure may be provided with a coating layer coated with molten zinc. [Effects of the Invention]

[0014] According to the foundation structure for an agricultural solar power generation structure of the present invention, the foundation piles and connecting pieces that make up the foundation structure for installing the support pillars are constructed from a single part, which reduces the amount of work required for the solar power generation structure, improves workability, shortens the assembly and installation period, and reduces installation costs.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0017] The terms used in the present invention are defined in consideration of the functions in the present invention, and may differ depending on the intentions or practices of users or operators. Therefore, the definitions of these terms should be interpreted in terms of meanings and concepts that correspond to the technical matters of the present invention.

[0018] Furthermore, the embodiments of the present invention do not limit the scope of the rights of the present invention, but are merely examples of the elements shown in the claims of the present invention, and are embodiments that include elements that are included in the technical idea throughout the specification of the present invention and can be replaced as equivalents in the elements of the claims.

[0019] Furthermore, optional terms in the following embodiments are used to distinguish certain components from other components, and the components are not limited by those terms.

[0020] Therefore, in describing the present invention, if a detailed description of related publicly known techniques would obscure the gist of the present invention, that detailed description will be omitted.

[0021] 1 to 6 are diagrams showing the foundation structure of the agricultural solar power generation structure according to the present invention.

[0022] As shown in Figures 1 to 4, the agricultural solar power generation structure of the present invention comprises a foundation structure 100 that is fixedly installed in the ground, a support pole 200 that is erected on the foundation structure 100, and a solar module (not shown) that is installed on the support pole 200 and produces electricity using solar energy, i.e., generates power.

[0023] In particular, as shown in Figure 4, the foundation structure 100 comprises a foundation pile 110 that is buried in the ground, a plurality of support piece portions 120 that are arranged opposite the upper end of the foundation pile 110 that is exposed above ground, and a plurality of fixing pieces 140 that are arranged opposite each other between the two support piece portions 120.

[0024] In this case, by forming the plurality of support piece portions 120 integrally with the foundation piles 110, the number of parts constituting the foundation 100 can be reduced.

[0025] Furthermore, the support piece portion 120 of the foundation structure 100 is further provided with a receiving piece portion 123 which is bent from the support piece portion 120 toward the foundation pile 110 and integrally formed with the foundation pile 110, and one end (lower end) of the support piece portion 120 which is connected to the receiving piece portion 123 is bent and formed with a bent portion 125 which protrudes outward and is recessed.

[0026] With the bent portion 125 formed in this manner, the support piece portion 120 at the upper part of the bent portion 125 has elasticity that allows its entire surface to be easily bent toward or away from the receiving piece portion 123 in the opposing direction.

[0027] In particular, when there is no bending portion 125 as in the present invention, the two support piece portions 120 are installed in the form of cantilevers rising upward from each receiving piece portion 123, so when a support pillar 200 is placed between the two support piece portions 120 and the two support piece portions 120 are screwed to both sides of the support pillar 200, the support piece portions 120 do not easily bend from the receiving piece portions 123 toward the support pillar 200, and as shown in Figure 7, only the fastening point or the upper end portion that is screwed is bent toward the support pillar 200 and comes into local contact with the support pillar 200.

[0028] As a result, the two support pieces 120 cannot come into close contact with both side surfaces of the support 200, but only come into contact locally, making it impossible to maintain the support 200 firmly fixed.

[0029] For this reason, in the present invention, a bending portion 125 is formed at the lower end of the support piece portion 120, which is connected to the receiving piece portion 123, which is the fixed end of the support piece portion 120, and is bent and protruded on the outside of the support piece portion 120, i.e., on the opposite side of the surface where the two support piece portions 120 face each other.When the two support piece portions 120 are screwed to both side surfaces of the support 200, the bending portion 125 allows the two support piece portions 120 to be easily bent in the opposing direction, and they can be arranged in a state of face-to-face contact with both side surfaces of the support 200.

[0030] Therefore, by providing the two support pieces 120 in close contact with the surface of both sides of the support pole 200 over as large an area as possible, the support pole 200 can be firmly fixed.

[0031] Furthermore, since the foundation structure 100 as described above is installed outdoors, the entire foundation structure 100 or at least the multiple support piece portions 120 and receiving piece portions 123 integrally formed on the foundation piles 110 are coated with a molten zinc coating layer to prevent rust from occurring in advance.

[0032] At this time, the molten zinc coating is usually performed by immersing the foundation structure 100 or multiple support pieces 120 and receiving pieces 123 in a furnace in which pure zinc is melted. During the drying process of the coated molten zinc, the molten zinc coated on the entire surface of the support piece 120 flows down and collects at the boundary between the support piece 120 and the receiving piece 123, i.e., on the inner corner side. When the drying of the molten zinc is completed in this state, solidified molten zinc lumps will be formed and present at the inner corners of the support piece 120 and the receiving piece 123.

[0033] As a result, the support pillar 200 erected between the two support pieces 120 cannot be seated accurately on the receiving piece 123 due to such molten zinc blocks, and is caused to float upward by the molten zinc blocks, resulting in it being installed at an angle, and the installation of the support pillar 200 is not carried out firmly.

[0034] Therefore, in the present invention, by forming a bending portion 125 that protrudes outward at the lower end of the support piece portion 120 that is connected to the receiving piece portion 123, the molten zinc flowing down from the support piece portion 120 flows into the bending portion 125 and becomes a molten zinc block within the bending portion 125, so that the installation of the support pillar 200 that is erected on the receiving piece portion 123 is not hindered.

[0035] On the other hand, the foundation pile 110 constituting the foundation structure 100 as described above has its lower end formed in a pointed cone shape so that it can be easily driven into the ground, and its circumferential surface is provided with screw-like blades as shown in Figure 1 or helical blades as shown in Figure 6, so that the foundation pile 110 can be easily driven into the ground, and when the foundation pile 110 is rotated in the driven state, the foundation pile 110 can be easily dug into the ground and buried.

[0036] The upper end of the foundation pile 110 is exposed above ground, and a plurality of support pieces 120 are integrally formed on both sides of the exposed upper end of the foundation pile 110 in a facing state, as described above.

[0037] In addition, the support piece portion 120 as described above has a plurality of triangular elongated holes 121 formed therein, which correspond to the first connecting holes 201 of the support 200 described later. Specifically, a single elongated hole is formed in the upper part of the support piece portion 120, and a plurality of elongated holes are formed in the lower part of the support piece portion 120 on both sides of the upper elongated hole 121.

[0038] The long hole 121 of such a support piece portion 120 is formed long in the vertical direction and is arranged to be aligned with and communicate with the first connecting hole 201 of the support 200, so that the bolt passes through the long hole 121 of the support piece portion 120 and the first connecting hole 201 of the support 200 in sequence and fastens them together.

[0039] In this case, the single elongated hole 121 located at the top of the support piece portion 120 is a fixing hole for fixing the erected support 200, and may be formed as a circular hole instead of an elongated hole.

[0040] The multiple long holes 121 located at the bottom of the support piece portion 120 are hinge holes for rotating the support pillar 200 described below from the support piece portion 120 to make it stand upright. By providing multiple long holes 121 on both sides of the bottom of the support piece portion 120, the support pillar 200 can be freely tilted in one direction or the other direction on the opposite side of the support piece portion 120 by using one of the long holes 121 at the bottom of both sides.

[0041] Such a long hole 121 is formed long in the vertical direction of the support piece portion 120, and when the first connecting hole 201 of the support 200 is fastened with a bolt, it moves up and down along the long hole 121, thereby preventing the lower end of the support 200 from getting caught on the receiving piece portion 123 of the support piece portion 120 and interfering with it when the support 200 rotates.

[0042] Furthermore, seating grooves 122 having "V"-shaped steps extending downward from the top surface are formed at regular intervals at the upper end of the support piece portion 120, and locking protrusions 141 of the fixing piece 140, which will be described later, are inserted and coupled into the seating grooves 122.

[0043] In addition, the receiving piece portion 123 is a flat plate bent vertically inward at the lower end of the supporting piece portion 120, and the lower surface of the support pillar 200 described later is seated and supported on its flat surface, thereby distributing the load of the support pillar 200 and the solar power generation structure.

[0044] Furthermore, the receiving piece portion 123 is formed with a plurality of insertion holes 124 into which insertion protrusions 142 protruding downward from the underside of the fixed piece 140 described later are inserted and connected so as to fit into each other, and by combining the insertion holes 124 with the insertion protrusions 142, the fixed piece 140 is fixed in position between the two support piece portions 120, thereby firmly supporting the upright support 200 and preventing the support 200 from rotating.

[0045] A gap 126 is formed between the two receiving pieces 123, and this gap 126 allows the undried liquid molten zinc coated on the support piece 120 and the receiving piece 123 to flow down and be discharged, thereby preventing the presence of dried molten zinc blocks on the receiving piece 123.

[0046] In addition, the above-mentioned receiving piece portion 123 is installed with a length and width that protrudes from the outside of the foundation pile 110 so as to have an area larger than the cross-section of the foundation pile 110 in order to firmly support the support 200.

[0047] As a result, a reinforcing rib 130 that supports the receiving piece 123 is formed below the receiving piece 123, thereby ensuring the robust durability of the receiving piece 123.

[0048] In particular, such reinforcing ribs 130 are spaced apart at equal intervals on the lower part of the receiving piece portion 123, and each reinforcing rib 130 is arranged to protrude from the outer surface of the foundation pile 110 toward the outer corner of the receiving piece portion 123.The multiple reinforcing ribs 130 are arranged in an "X"-shaped structure that crosses the multiple rectangular receiving piece portions 123, thereby firmly reinforcing the durability of the receiving piece portion 123.

[0049] As shown in FIG. 4, the fixing pieces 140 are flat plates that are installed across the two support piece portions 120, and on their surfaces are formed connecting holes 143 that are fastened with bolts to the second convenient holes 202 of the support 200 described later.

[0050] The connecting hole 143 of such a fixing piece 140 is located between the upper long hole 121 and the lower long hole 121 of the support piece portion 120, in order to prevent interference between the bolt fastened to the connecting hole 143 of the fixing piece 140 and the bolts fastened to the long holes 121 of the support piece portion 120.

[0051] On both sides of the upper end of the fixing piece 140, locking protrusions 141 that protrude outward are formed, and the two locking protrusions 141 are inserted into and seated in seating grooves 122 of the support piece portion 120.

[0052] Furthermore, on both sides of the lower end of the fixed piece 140, insertion protrusions 142 that protrude downward are formed, and the two insertion protrusions 142 are inserted into and connected to insertion holes 124 formed in each receiving piece portion 123 of the two support piece portions 120.

[0053] As a result, the fixing pieces 140 are joined by inserting the locking protrusions 141 at the upper ends into the seating grooves 122 of the support piece portions 120, and by inserting the insertion protrusions 142 at the lower ends into the insertion holes 124 of each receiving piece portion 123, the multiple fixing pieces 140 are joined and fixed between the two support piece portions 120, sandwiching the erected support column 200 between them, and supporting the erected support column 200, thereby firmly blocking and preventing rotation of the erected support column 200.

[0054] On the other hand, the support 200 installed on the foundation structure 100 as described above has a circular first connecting hole 201 formed on both sides of its lower end, which is connected to the long hole 121 of the support piece portion 120 in a manner that coincides with it, and the first connecting hole 201 is formed to have a triangular shape corresponding to the long hole 121 of the support piece portion 120.

[0055] Then, on both side surfaces of the other side of the support 200 perpendicular to the first connecting hole 201, a second connecting hole 202 having a perfect circle shape is formed to be aligned with and connected to the connecting hole 143 of the fixing piece 140.

[0056] Therefore, the foundation structure 100 constituting the solar power generation structure according to the present invention as described above is integrally formed with a pair of support piece portions 120 and receiving piece portions 123 facing each other at the upper end of the foundation pile 110, and therefore, as shown in Figure 5, the labor required to erect the support pillar 200 between the two support piece portions 120 and receiving piece portions 123 is reduced and workability is improved, thereby shortening the installation period of the solar power generation structure and reducing installation costs.

[0057] Furthermore, the two support piece portions 120 that are bent upward from the two receiving piece portions 123 and stand upright have bent portions 125 formed at the lower ends that join with the receiving piece portions 123, which are bent outward and protrude.The two support piece portions 120 can be easily bent in opposite directions at each receiving piece portion 123 by these bent portions 125, so that when the two support piece portions 120 are fastened to both side surfaces of the support 200 with bolts, as shown in Figure 5, the two support piece portions 120 are arranged in close contact with both side surfaces of the support 200, thereby firmly fixing the support 200.

[0058] The present invention has been described in detail above using specific embodiments, but these are for the purpose of specifically explaining the present invention and the present invention is not limited to these. It goes without saying that modifications and improvements can be made by those having ordinary knowledge in the relevant field within the technical spirit of the present invention.

[0059] Any simple modifications or variations of the present invention are intended to be included in the present invention, and the specific scope of protection of the present invention will be defined by the claims. [Explanation of symbols]
