Description

Foundation structure of agricultural solar power generation structure

[0001] The present invention relates to a basic structure of an agricultural solar power generation structure, and more particularly, to a basic structure of an agricultural solar power generation structure that reduces the number of parts constituting the basic structure and thus reduces the assembly work of the solar power generation structure.

[0002] Typically, a solar power generation system is constructed by installing a support structure, assembling various frames on the support structure, and then installing solar modules on the frame. The solar modules generate electricity using solar energy, and the frame is installed at an angle to face the direction of the sun in order to maximize the amount of electricity produced by the solar modules.

[0003] These solar power generation systems have recently been installed and used on farmland, and by conducting solar power generation using solar energy while farming, profits are generated through sales of electricity production, and 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 invention has proposed an ‘agricultural solar power generation structure’ in registered patent No. 10-2457075 (hereinafter referred to as ‘prior art document’).

[0005] In prior art literature, a joint device for a solar power generation structure is disclosed, which includes a foundation pile installed by being driven into the ground, a support member standing on the foundation pile and on which a solar power generation structure is installed, and a connecting member and a fixing member connecting the support member and the foundation pile to fix the rotating support member in an upright state, wherein the connecting member is a first support member that is rotatably connected to the support member on the foundation pile and fixes the support member in an upright state; A joint device for a solar power generation structure is disclosed, comprising: a second support piece formed as an extension from a first support piece and connected to a foundation pile; the first support piece includes a support plate having a plurality of long holes that are connected to a pillar and a fixing piece that is hooked thereto; and a support plate formed as an extension from the support plate and having a lower surface in contact with the pillar and an upper surface in which the pillar is seated and supported; the second support piece includes a first cover plate that surrounds an outer circumferential surface of the foundation pile; and a second cover plate that is formed as an extension in a stepped state on both sides of the first cover plate, the first cover plate is formed as an outwardly stepped extension from the second cover plate to have a larger diameter than the second cover plate, and is provided so as to be rotated and positionally adjusted while receiving a joining projection protruding outward from the foundation pile; and a reinforcing rib that is connected to the first support piece is formed on the second cover plate.

[0006] In the prior art document disclosed in this way, the two supporting pieces of the connecting piece are connected to the upper part of the foundation pile buried in the ground in a state of wrapping the foundation pile by facing each other, and in this state, a support is inserted between the two supporting pieces of the connecting piece and connected in an upright state, so that the support is installed in an upright state on the foundation pile.

[0007] However, in conventional solar power generation systems, in order to install a support on top of a foundation pile, a connecting piece must be installed on the upper part of the foundation pile. At this time, the connecting piece is composed of multiple support pieces, and the two support pieces are connected and fixed in a state of facing each other on both sides of the upper part of the foundation pile to complete the installation of the connecting piece.

[0008] In this way, the foundation structure, including the foundation piles and connecting pieces for installing the support, is composed of an unnecessary number of components, which increases the work load and reduces workability, and not only does it take a long time for assembly and installation, but it also increases the installation cost, which is a disadvantage.

[0012] Republic of Korea Patent No. 10-2457075

[0013] Accordingly, the present invention has been devised to solve the problems of the prior art as described above, and its purpose is to provide a foundation structure for an agricultural solar power generation structure that can reduce the work man-hours and construction time of the solar power generation structure by simplifying the components that constitute the foundation structure for installing a support.

[0014] The foundation structure of an agricultural solar power generation structure according to the present invention for achieving the above-described purpose is a foundation structure of a solar power generation structure for installing a pillar of the solar power generation structure, characterized in that a plurality of support pieces are provided to face each other on a foundation pile buried in the ground and are formed integrally on the foundation pile.

[0015] In addition, the support section of the foundation structure may further include a support section that is formed by bending from the support section toward the foundation pile and is fixed to the foundation pile, and a bend section that is recessed and bent to protrude outward may be formed at one end of the support section connected to the support section, so that the support section that is screw-connected to the pillar may be provided in a state of being in close contact with the pillar.

[0016] Additionally, the base structure may be provided with a coating layer made of molten zinc.

[0017] According to the foundation structure of the agricultural solar power generation structure of the present invention, the foundation pile and connecting piece constituting the foundation structure for installing the support are configured as a single part, thereby reducing the number of work hours for the solar power generation structure, improving workability, shortening the construction time due to assembly and installation, and reducing the installation cost.

[0026] The terms used in the present invention are terms defined in consideration of the functions of the present invention, and since these may vary depending on the intention or custom of the user or operator, the definitions of these terms should be interpreted as meanings and concepts that are consistent with the technical aspects of the present invention.

[0027] In addition, the embodiments of the present invention do not limit the scope of the present invention, but are merely exemplary matters of the components presented in the claims of the present invention, and are embodiments that include components that are included in the technical idea throughout the specification of the present invention and can be replaced as equivalents in the components of the claims.

[0028] Additionally, the optional terms in the examples below are used to distinguish one component from another, and the components are not limited by the terms.

[0029] Accordingly, in describing the present invention, detailed descriptions of related known technologies that may unnecessarily obscure the gist of the present invention are omitted.

[0030]

[0031] The attached drawings, Figures 1 to 6, are drawings showing the basic structure of an agricultural solar power generation structure according to the present invention.

[0032] As shown in FIGS. 1 to 4, the agricultural solar power generation structure according to the present invention includes a foundation structure (100) that is fixedly installed on the ground, a support (200) that is installed to stand on the foundation structure (100), and a solar module (not shown) that is installed on the support (200) to generate electricity, that is, generate power, using solar energy.

[0033] In particular, the foundation structure (100) includes, as illustrated in FIG. 4, a foundation pile (110) installed by being buried in the ground, a plurality of support pieces (120) provided to face each other at the upper end of the foundation pile (110) exposed above the ground, and a plurality of fixing pieces (140) provided to face each other between the two support pieces (120).

[0034] At this time, a plurality of support pieces (120) are formed integrally on each of the foundation piles (110), thereby reducing the number of parts constituting the foundation structure (100).

[0035] In addition, the support piece (120) of the foundation structure (100) is further provided with a support piece (123) that is formed by bending from the support piece (120) toward the foundation pile (110) and is integrally formed with the foundation pile (110), and a bend portion (125) that protrudes outward and is sunken is formed by bending at one end (lower end) of the support piece (120) that is connected to the support piece (123).

[0036] By the bending portion (125) formed in this way, the support portion (120) on the upper portion of the bending portion (125) has elasticity that allows the front surface to be easily bent so as to approach or move away from the support portion (123) in a direction facing each other.

[0037] In particular, in the case where there is no bending portion (125) as in the present invention, since both support pieces (120) are installed in a cantilever shape that is erected upward from each support piece (123), when the support pieces (120) are fastened to both sides of the support piece (200) with a support (200) provided between the two support pieces (120) by screws, the support piece (120) does not bend well toward the support piece (200) at the support piece (123), so only the fastening portion where the screw is fastened or the upper end where the screw is fastened bends toward the support piece (200) as in FIG. 7 and locally comes into contact with the support piece (200).

[0038] As a result, since the two support pieces (120) do not come into close contact with both sides of the support (200) but only come into local contact, the fixing state of the support (200) cannot be firmly maintained.

[0039] Accordingly, in the present invention, by forming a bending portion (125) that is bent and protrudes toward the outer side of the support portion (120), that is, the opposite side of the surface where both support portions (120) face each other, at the lower end of the support portion (120) connected to the support portion (123), which is the fixed end of the support portion (120), when both support portions (120) are screw-fastened to both sides of the support post (200), the two support portions (120) can be easily bent in the direction where they face each other by the bending portion (125) and be provided in a state of being in close contact with both sides of the support post (200).

[0040] Accordingly, the support member (120) is provided in close contact with the widest possible area on both sides of the support member (200), thereby firmly fixing the support member (200).

[0041] In addition, since the above-described foundation structure (100) is installed outdoors, the plurality of support pieces (120) and support pieces (123) integrally formed on the entire foundation structure (100) or at least the foundation pile (110) form a coating layer coated with molten zinc to prevent rust from occurring in advance.

[0042] At this time, the coating of molten zinc is usually performed by immersing the base structure (100) or a plurality of support pieces (120) and support pieces (123) in a furnace in which pure zinc is melted, and at this time, in the process of drying the coated molten zinc, the molten zinc coated on the entire surface of the support piece (120) flows down and gathers at the boundary between the support piece (120) and the support piece (123), that is, toward the inner corner, and when the drying of the molten zinc is completed in this state, a lump of molten zinc is formed and exists at the inner corner of the support piece (120) and the support piece (123).

[0043] Then, the support (200) that is installed standing up between the two support pieces (120) by the molten zinc lumps is not accurately seated on the support piece (123) but is installed tilted upward by the molten zinc lumps, so the installation of the support (200) is not solid.

[0044] Accordingly, in the present invention, by forming a folded portion (125) that protrudes outward at the lower end of the support portion (120) connected to the support portion (123), molten zinc flowing down from the support portion (120) flows into the folded portion (125) and forms a lump of molten zinc within the folded portion (125), thereby not interfering with the installation of the support pillar (200) that is installed standing up on the support portion (123).

[0045]

[0046] Meanwhile, the foundation pile (110) constituting the above-described foundation structure (100) is formed in a pointed cone shape so that its lower part can be easily driven into the ground, and its circumference is provided with a screw wing as in FIG. 1 or a helical wing as in FIG. 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 easily dig into the ground and be buried.

[0047] The upper part of the foundation pile (110) is exposed above the ground, and on both sides of the upper part of the exposed foundation pile (110), a plurality of support pieces (120) are formed integrally facing each other as described above.

[0048] In addition, in the support member (120) as described above, a plurality of long holes (121) corresponding to the first connecting hole (201) of the support member (200) to be described later are formed in a triangular shape. Specifically, a single long hole is formed in the upper part of the support member (120), and a plurality of long holes are formed in the lower part of the support member (120) on both sides of the upper long hole (121).

[0049] The long hole (121) of the support member (120) is formed in a vertically elongated state and is provided in a state of being in line with and connected to the first connecting hole (201) of the support member (200), so that the bolt is fastened by sequentially penetrating the long hole (121) of the support member (120) and the first connecting hole (201) of the support member (200).

[0050] At this time, the single long hole (121) located on the upper part of the support member (120) is a fixing hole for fixing the erected support (200), and may be formed as a hole in the garden rather than a long hole.

[0051] In addition, the plurality of long holes (121) located at the lower portion of the support member (120) are hinge holes for rotating and standing up the support member (200) to be described later in the support member (120). By providing a plurality of long holes (121) on each of the lower sides of the support member (120), the support member (200) can be freely laid down in one direction of the support member (120) or in the other direction on the opposite side through the long holes (121) on one side among the long holes (121) on the lower portions of both sides.

[0052] Such a long hole (121) is formed long in the vertical direction of the support member (120), so that when the first connecting hole (201) of the support member (200) is connected with a bolt, it moves up and down along the long hole (121), thereby preventing the lower part of the support member (200) from being caught and interfered with by the support member (123) of the support member (120) when the support member (200) rotates.

[0053] And, on the upper part of the support member (120), a settling groove (122) is formed at regular intervals in a “V” shape from the upper surface downward, and a catch (141) of a fixed member (140) to be described later is inserted and joined into the settling groove (122).

[0054] In addition, the support piece (123) is a flat plate that is vertically bent inwardly facing each other at the lower end of the support piece (120), and the lower surface of the support (200), which will be described later, is provided on the flat surface to be supported, thereby distributing the load of the support (200) and the solar power generation structure.

[0055] In addition, a plurality of insertion holes (124) are formed in the support part (123), into which insertion protrusions (142) protruding downward from the lower surface of the fixed part (140) to be described later are each inserted and joined in a shape-fitting manner, and by the combination of the insertion holes (124) and the insertion protrusions (142), the fixed part (140) is provided to be fixed in position between the two support parts (120), thereby firmly supporting the erected support (200) and preventing rotation of the support (200).

[0056] In addition, a gap (126) is formed between the two supporting pieces (123), and through this gap (126), the liquid molten zinc coated on the supporting piece (120) and the supporting piece (123) before drying flows down and is discharged, thereby preventing the presence of dried molten zinc lumps on the supporting piece (123).

[0057] In addition, the support piece (123) as described above is installed with a length and width that protrudes outward from the foundation pile (110) so as to have an area wider than the cross-section of the foundation pile (110) in order to firmly support the pillar (200).

[0058] In this way, a reinforcing rib (130) is formed at the lower part of the support piece (123) to support the support piece (123), thereby ensuring the sturdy durability of the support piece (123).

[0059] In particular, these reinforcing ribs (130) are provided in a plurality of pieces spaced at equal intervals on the lower portion of the support piece (123), and each reinforcing rib (130) is provided so as to protrude from the outer surface of the foundation pile (110) toward the outer corner of the support piece (123), so that the plurality of reinforcing ribs (130) are provided in a structure that crosses the plurality of support pieces (123) forming a rectangle in an “X” shape, thereby firmly reinforcing the durability of the support piece (123).

[0060] In addition, the fixed piece (140) is a plurality of flat plates installed across the space between the two support pieces (120), as shown in FIG. 4, and a connecting hole (143) is formed on the surface thereof to be fastened with a bolt to the second connecting hole (202) of the support (200) to be described later.

[0061] The joining hole (143) of the fixed piece (140) is positioned between the upper hole (121) and the lower hole (121) of the support piece (120), to prevent interference between the bolts fastened to the joining hole (143) of the fixed piece (140) and the bolts fastened to the holes (121) of the support piece (120).

[0062] On both sides of the upper portion of the fixed piece (140), a hook portion (141) protruding outward is formed, and both hook portions (141) are inserted into and fixed in the fixing groove (122) of the support piece (120).

[0063] And, insertion protrusions (142) protruding downward are formed on both sides of the lower portion of the fixed piece (140), and both insertion protrusions (142) are inserted into and combined into insertion holes (124) formed in each support piece (123) of both support pieces (120).

[0064] In this way, the fixing member (140) is inserted and joined by the catch portion (141) of the upper portion into the fixing groove (122) of the support member (120), and the insertion portion (142) of the lower portion is inserted and joined by the insertion hole (124) of each support member (123), so that the plurality of fixing members (140) are fixedly joined between the two support members (120) with the standing support member (200) interposed therebetween, thereby supporting and supporting the standing support member (200), thereby firmly blocking and preventing the rotation of the standing support member (200).

[0065]

[0066] Meanwhile, the support (200) installed and provided on the above-described foundation structure (100) has a first connecting hole (201) in the shape of a garden formed on both sides of the lower portion thereof to be aligned with the long hole (121) of the support piece (120), and the first connecting hole (201) is formed to form a triangular shape corresponding to the long hole (121) of the support piece (120).

[0067] And, on both sides of the support (200) in the other direction perpendicular to the first joint hole (201), a second joint hole (202) in the shape of a garden is formed to be aligned with and joined to the joint hole (143) of the fixed piece (140).

[0068]

[0069] Accordingly, since the foundation structure (100) constituting the solar power generation structure according to the present invention is formed integrally with a pair of support pieces (120) and support pieces (123) facing each other at the upper end of the foundation pile (110), as shown in FIG. 5, the work man-hours for erecting and installing the pillar (200) between the two support pieces (120) and support pieces (123) are reduced, thereby improving workability, and accordingly, the construction time for installing the solar power generation structure is shortened, and the installation cost is reduced.

[0070] In addition, since the two support pieces (120) that are bent upward from the two support pieces (123) and erected have a bent portion (125) that is bent outwardly and protrudes at the lower end connected to the support pieces (123), the two support pieces (120) can be easily bent in a direction facing each other at each support piece (123) by the bent portion (125), so that when the two support pieces (120) are fastened to both sides of the support (200) with bolts as shown in FIG. 5, the support (200) can be firmly fixed as the two support pieces (120) are provided in a state of being in close contact with both sides of the support (200).

[0071]

[0072] 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 is clear that modifications and improvements can be made by those skilled in the art within the technical spirit of the present invention.

[0073] 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.
