Abstract
Description
Technology Field
[0001] The present invention relates to a corrosion prevention device for foundation piles of a photovoltaic power plant structure, and more specifically, to a corrosion prevention device for foundation piles of a photovoltaic power plant structure in which an anode supply member that supplies a large amount of electrons to a foundation pile of a structure installed by driving it into the ground is installed by embedding the anode supply member in the ground where the foundation pile is driven, and the anode supply member and the foundation pile are connected by a wire, thereby causing the foundation pile to become an electron-excessive state overall and a negative state, which suppresses the corrosion phenomenon of the foundation pile, thereby extending the lifespan of the foundation pile, and further enhancing product reliability by preventing the foundation pile from easily corroding even when installed on coastal ground with high salt content. Background Technology
[0003] Generally, foundation piles are used as foundation facilities for structures.
[0004] Recently, solar power generation facilities are being installed in accordance with national policies that favor eco-friendly and pollution-free energy businesses. Previously, concrete foundations using concrete blocks were mainly used for structures. However, concrete foundations were problematic because the construction process was complex, resulting in long construction periods, high construction costs, and the generation of environmental waste during demolition. Consequently, metal foundation piles are now mostly used as the foundation for structures instead of concrete foundations when constructing solar power plants.
[0005] Currently, various types of products are being used as foundation piles for solar power structures, including screw piles and helical piles, as well as U-piles, square tubes, steel pile foundations, and Posmac columns.
[0006] The types of foundation piles used for solar power structures can be broadly divided into two types: one is a 'separated foundation pile' in which the foundation part and the structure column are separated, and the other is an 'integrated foundation pile' in which the foundation part and the structure column are one.
[0007] Screw piles and helical piles are representative products of separated foundation piles, while U-piles, square pipes and C-shaped steel for piling, steel pile foundations, and Posmac columns are products of integrated foundation piles.
[0008] FIG. 1 illustrates a state in which conventional foundation piles are constructed as foundation facilities,
[0009] FIG. 1 (a) illustrates an embodiment in which a screw pile is applied as a separable foundation pile, wherein the foundation pile (1) is installed by driving it into the ground (8), the foundation pile (1) has a screw (3) formed to protrude spirally from the bottom of the body part (2), and an upper plate (4) is installed on the upper part of the body part (2).
[0010] FIG. 1 (b) illustrates an embodiment in which a square pipe, which is an integral foundation pile, is used as a foundation pile. The square pipe is driven into the ground (8) to a predetermined depth to serve as a foundation facility, and the upper part of the square pipe above the ground (8) is utilized as a column of the structure.
[0011] However, when conventional foundation piles are installed by being buried in coastal ground with high salinity, corrosion caused by salt progresses rapidly, shortening their lifespan, and there is a problem that frequent maintenance is required to prevent this. The problem to be solved
[0013] Accordingly, the present invention, which aims to solve the above problems, provides a corrosion prevention device for a foundation pile of a photovoltaic power plant structure, wherein an anode supply member that supplies a large amount of electrons to a foundation pile installed by driving it into the ground is installed so as to be embedded in the ground where the foundation pile is driven, and the anode supply member and the foundation pile are connected by a wire, thereby causing the foundation pile to become an electron-excessive state overall and a negative state, which suppresses the corrosion phenomenon of the foundation pile, thereby extending the lifespan of the foundation pile, and further enhancing product reliability by preventing the foundation pile from corroding easily even when installed on coastal ground with high salt content. means of solving the problem
[0015] The present invention for achieving the above objective
[0016] A foundation pile (1) is installed so as to be buried in the ground (8), and
[0017] An anode supply member (10) that supplies a large amount of electrons to a foundation pile (1) is installed so as to be buried on one side of the ground (8) where the foundation pile (1) is driven, and
[0018] Connect the positive supply member (10) and the foundation pile (1) with a wire (16).
[0019] It is characterized by being configured such that corrosion is suppressed when the base pile (1) becomes a negative state due to a large amount of electrons supplied from the anode supply member (10). Effects of the invention
[0021] According to the present invention, the foundation pile becomes an electron-excessive state overall and becomes a cathodic state, thereby suppressing the corrosion phenomenon of the foundation pile and extending the lifespan of the foundation pile. Furthermore, even if the foundation pile is installed on coastal ground with high salt content, it does not easily corrode, so the effect of further increasing product reliability can be expected.

[0027] A foundation pile (1) is installed so as to be buried in the ground (8), and
[0028] An anode supply member (10) that supplies a large amount of electrons to a foundation pile (1) is installed so as to be buried on one side of the ground (8) where the foundation pile (1) is driven, and

[0039] The corrosion prevention device for the foundation pile of the structure of the present invention is broadly composed of a foundation pile (1) and an anode supply member (10).
[0040] In the description of the present invention, the referenced drawings illustrate an embodiment in which a screw pile is used as the foundation pile, but in reality, it can be applied to various metal foundation piles in addition to screw piles, such as helical piles, U-piles, square tubes, C-shaped steel, steel pile foundations, and Posmac columns.
[0041] A screw pile, which is a representative foundation pile (1), is made entirely of metal and is equipped with a body part (2) that is driven into the ground, and a screw (3) is formed to protrude spirally from the lower part of the body part (2), and an upper plate (4) is installed on the upper part of the body part (2).
[0042] A structure for installing a solar power generation facility is installed on the upper side of the top plate (4).
[0043] In addition, in the present invention, a zinc plating layer (5) is formed on the surface of the body part (2) to help prevent corrosion.
[0044] In addition, a connection hole (6) for connecting the wire (16) described later is formed in the upper plate (4), and a connection bolt (7) is coupled to the connection hole (6) so that the wire (16) can be electrically connected to the upper plate (4).
[0045] If the top plate (4) is not configured on the foundation pile, the wire (16) may be directly connected to the upper part of the foundation pile or to a metal structure installed on top of the foundation pile.
[0046] Meanwhile, the anode supply member (10) is intended to supply a large amount of electrons to the base pile (1), and is manufactured by casting an anode material (11) made of magnesium alloy or zinc alloy, and an iron core (12) is installed in the center of the anode material (11), with the iron core (12) deeply embedded in the center of the anode material (11) and configured so that one end of the iron core (12) is exposed to the outside of the anode material (11) and connected to a wire (16).
[0047] And, the connection part between the wire (16) and the iron core (12) is sealed using a separate sealing joint (13), and the above-mentioned anode material (11) is housed in a separate case (14).
[0048] The inside of the case (14) is filled with a filler (15) to maintain moisture inside the case (14).
[0049] In addition, to ensure a sealed connection between the iron core (12) and the wire (16), a coupling groove (19) is formed at one end of the anode material (11) as shown in FIG. 5, and the end of the sealing joint (13) is formed at an angle so that it is fitted into the coupling groove (19). A fitting groove (17) into which the iron core (12) is fitted is formed at the end of the sealing joint (13), and a terminal (18) for electrically connecting to the iron core (12) is formed on the inner wall of the fitting groove (17), and the terminal (18) is configured to be electrically connected to the wire (16).
[0050] The construction method of the foundation pile corrosion prevention device of the present invention is described as follows.
[0051] First, a foundation pile is driven into the ground (8) and installed, and a pit is dug in the ground (8) at a predetermined distance from where the foundation pile (1) is installed, and then an anode supply member (10) is buried in the pit.
[0052] At this time, the anode supply member (10) can be installed vertically as shown in FIG. 2 or horizontally as shown in FIG. 3.
[0053] After pulling out the wire (16) that is electrically connected to the anode material (11) of the anode supply member (10) above the ground, the end of the wire (16) is positioned between the head of the connecting bolt (7) that is connected to the connecting hole (6) of the upper plate (4) of the foundation pile and the upper plate (4), and then the connecting bolt (7) is tightened so that the wire (16) is connected to the foundation pile (1).
[0054] In cases where the top plate (4) is not present on the foundation pile (1), the wire (16) may be connected to the upper part of the foundation pile or to the lower part of the column structure installed in combination with the foundation pile to electrically connect the positive supply member and the foundation pile, or the wire (16) may be directly connected to the body of the foundation pile.
[0055] As described above, when the positive material (11) is connected to the base pile (1) by a wire (16), a large amount of electrons supplied from the positive material (11) are supplied to the surface of the body part (2) of the base pile (1), and the surface of the base pile (1) becomes a negative state, thereby suppressing electron movement of the base pile (1), so that the effect of preventing or minimizing corrosion caused by electron movement can be expected.
[0056] In the description of the present invention, an example in which a screw pile is applied as the foundation pile (1) has been described, but in reality, in addition to screw piles, it can be applied to various types of metal foundation piles such as helical piles, U-piles, square pipes, C-shaped steel, steel pile foundations, and Posmac columns.
