Description

Technical Field

[0001] The present invention relates to a floating solar power generation device, and more particularly to a solar cell panel tilt support member for a floating solar power generation device that can stably support a solar cell panel at a fixed position with only simple installation and can easily change the tilt angle of the solar cell panel according to the latitude of the installation location.

Background Art

[0002] Recently, regulations for suppressing carbon dioxide emissions have been implemented worldwide, and the development of new power generation devices that do not emit carbon dioxide is required.

[0003] As a power generation device that uses clean energy without emitting carbon dioxide, a power generation device that uses sunlight is typically cited. In order to secure a wide installation area with abundant sunlight, many floating solar power generation devices in which solar cell panels are installed on the water surfaces of rivers, lakes, water storage ponds, dams, etc. are installed.

[0004] A floating solar power generation device includes a plurality of solar cell panels, and a profile assembly and a float that support the plurality of solar cell panels so as to be located on the water surface.

[0005] In a conventional floating solar power generation device, as shown in FIG. 1, in a state where a horizontal frame 11 in the lateral direction and a horizontal frame 12 in the longitudinal direction are cross-coupled, a front tilt frame 13a and a rear tilt frame 13b form a triangular structure and are provided in a state of being fixed to the longitudinal horizontal frame 12. A solar cell panel (not shown) is supported by the front tilt frame 13a and is provided in a tilted state. At this time, in order to support a solar cell panel having a wide width in the left-right direction, a combination body of the front tilt frame 13a and the rear tilt frame 13b is provided in a pair with a gap therebetween on both the left and right sides."

[0006] However, this method of supporting the solar panels involved the cumbersome and repetitive task of fastening each bracket 14, 15a, and 15b, resulting in a lengthy and time-consuming work process. Furthermore, if the cutting lengths of the front inclined frames 13a, which are provided in pairs on both the left and right sides, did not match, or if the cutting lengths of the rear inclined frames 13b did not match, the balance would be disrupted during installation, causing the tilt angle of the solar panels to deviate from the design value. This would necessitate disassembling and correcting the front and rear inclined frames 13a and 13b again. Moreover, if the inclined frames became uneven due to typhoons or strong winds and waves, damaging the solar panels, stable electricity production would be impossible.

[0007] Furthermore, if it is necessary to have different tilt angles for the solar panels depending on the latitude of the installation site, there is a difficulty in having to change the entire design, such as by making the cutting lengths of the front tilt frame 13a and the rear tilt frame 13b different in order to change the tilt angle of the front tilt frame 13a that directly supports the solar panels. [Overview of the project] [Problems that the invention aims to solve]

[0008] Therefore, the present invention was proposed to solve the above-mentioned conventional problems, and the object of the present invention is to provide a solar panel tilt support member for a floating solar power generation system that can stably support a solar panel in a fixed position with only simple installation and allows the tilt angle of the solar panel to be easily changed according to the latitude of the installation site. [Means for solving the problem]

[0009] To achieve the above objectives, the solar panel tilt support member according to the technical concept of the present invention is a solar panel tilt support member for supporting a solar panel in a floating solar power generation device consisting of a solar panel, a profile assembly and a float that support the solar panel so that it is positioned on the water surface, and comprises a lower fixing portion that is formed to be long in the front-rear direction and fixed to the vertical horizontal frame and the horizontal horizontal frame of the profile assembly, and an upper portion that branches off from the front end of the lower fixing portion, extends long and tilted upward to the rear, and supports the upper end of the solar panel from below. The technical features of this structure are that a lateral support frame and an inclined support portion that intersects and supports the lower lateral support frame that supports the lower end of the solar cell panel from below, and a rear end support portion that branches off from the rear end of the lower fixing portion, extends upward for a long distance, and then merges with the inclined support portion at its upper end, becoming one with the inclined support portion and forming a triangular structure together with the lower fixing portion and the inclined support portion, are integrally formed, and are arranged in pairs on both the left and right sides at a distance from each other to support the upper lateral support frame and the lower lateral support frame that support the solar cell panel.

[0010] Here, the lower fixing portion, the inclined support portion, and the rear end support portion may be characterized by being integrally molded together with a vertical panel portion formed vertically in a flat plate shape, a first horizontal panel portion formed horizontally along one end of the vertical panel portion and having a T-shaped cross-section with the vertical panel portion, a second horizontal panel portion formed horizontally along the other end of the vertical panel portion and having an inverted T-shaped cross-section with the vertical panel portion, and a plurality of first reinforcing ribs that protrude from the left and right sides of the vertical panel portion, respectively, with one end and the other end joined to the first horizontal panel portion and the second horizontal panel portion, respectively, to reinforce the strength so as not to deform the first horizontal panel portion and the second horizontal panel portion.

[0011] Furthermore, the first reinforcing rib may be characterized by comprising a straight vertical rib that orthogonally connects the first horizontal panel section and the second horizontal panel section, and an X-shaped inclined rib that connects the first horizontal panel section and the second horizontal panel section in an X-shape.

[0012] Furthermore, the inclined support portion may be formed in a shape that extends further to the rear after passing through the point where the rear end support portion merges, and the inclined support portion may have a lower bolt hole near the rear side from the point where it branches off from the lower fixing portion, and the lower bolt is fastened to the lower lateral support frame with the lower bolt passing through the lower bolt hole, and the rear end portion extending from the point where the rear end support portion merges has an upper bolt hole, and the upper bolt is fastened to the upper lateral support frame with the upper bolt passing through the upper bolt hole.

[0013] Furthermore, the upper bolt holes of the inclined support portion may be formed as elongated holes with an inner diameter wider in the front-to-back direction than in the left-to-right direction, thereby allowing for changes in the angle of the upper bolts when the installation height of the upper lateral support frame supporting the solar cell panel is changed in order to change the inclination angle of the solar cell panel.

[0014] Furthermore, in order to increase the tilt angle of the solar cell panel, the system may further include a space member provided between the tilt support portion and the upper lateral support frame, which separates the upper lateral support frame upward from the tilt support portion and has through holes that communicate with the tilt support portion so that the upper bolts pass through, corresponding to the upper bolt holes of the tilt support portion.

[0015] Furthermore, the space member may be characterized by comprising a lower support portion that is inserted into and supported on the outside of the inclined support portion, and an upper separation portion that is formed in a shape that extends upward from the lower support portion and supports the upper lateral support frame at a distance from the inclined support portion between the inclined support portion and the upper lateral support frame.

[0016] Furthermore, the lower support portion of the space member comprises a pair of lower side walls that are in close contact with the left and right sides of the inclined support portion, and a lower ceiling that connects the upper ends of the pair of lower side walls and is in contact with the upper surface of the inclined support portion; the upper separation portion of the space member comprises a pair of upper side walls that extend upward from the lower side walls, and an upper ceiling that connects the upper ends of the pair of upper side walls and is in contact with the lower surface of the upper lateral support frame; through holes are formed in the lower ceiling of the lower support portion and the upper ceiling of the upper separation portion, and guide pipes are further formed to connect the through holes in the lower ceiling and the through holes in the upper ceiling and guide the upper bolts.

[0017] Furthermore, the space member may be characterized by having multiple vertical plate-shaped reinforcing wing portions arranged along the circumferential direction of the guide tube, with their upper and lower ends in contact with and integrated with the lower and upper ceilings, respectively.

[0018] Furthermore, the lower ends of a pair of lower side walls belonging to the lower support portion of the space member may be further characterized by having detachment prevention protrusions that are bent in opposing directions and engage with the corners of the lower surface of the inclined support portion.

[0019] Furthermore, the space member may be provided in two or more types with different heights of the upper separation portion so that the tilt angle of the solar cell panel can be changed, and may be selectively installed on the tilt support portion.

[0020] Furthermore, the lower fixing portion may further include a pair of fastening panel portions that extend downward from the lower end of the left side and the lower end of the right side of the lower fixing portion, and which contact the left side and the right side of the vertical horizontal frame of the profile assembly, respectively, and the fastening panel portions have fastening holes for fastening bolts to the vertical horizontal frame, and a plurality of them are arranged at intervals along the length of the lower fixing portion.

[0021] Further, a plurality of second reinforcing ribs protruding vertically may be provided on the outer surface of the fastening panel portion, and it may be characterized in that the folding of the fastening panel portion can be prevented.

[0022] Further, at the rear end portion of the inclined support portion, a stepped portion is formed in a rising staircase shape that becomes higher toward the rear so that the upper horizontal support frame can be selectively supported at different heights, and an upper additional bolt hole is further formed so that an upper bolt can penetrate through each stepped portion, and a lower additional bolt hole is further formed corresponding to the upper bolt hole further formed in the stepped portion. It may be characterized by this.

[0023] Further, the upper surface of the stepped portion is formed as a surface that is more steeply inclined than the upper surface of the inclined support portion. When a plurality of stepped portions are formed, the stepped portion formed rearward is formed as a surface that is more steeply inclined than the stepped portion formed forward, so as to correspond to the changed inclination angle of the solar panel. It may be characterized by this.

Effect of the Invention

[0024] The solar panel inclination support member for the floating solar power generation device of the present invention can stably support the solar panel in a fixed position with only simple installation, and can easily change the inclination angle of the solar panel according to the latitude of the installation location.

[0025] Further, since the solar panel inclination support member for the floating solar power generation device of the present invention is configured to have a stepped portion in a rising staircase shape, an inclination angle changed with one frame can be obtained, so there is an advantage that it is not easily swayed by typhoons or strong wind and waves.

[0030] As shown in the figure, the solar panel tilt support member 100 according to an embodiment of the present invention is for supporting a solar panel 210 in a floating solar power generation system consisting of a solar panel 210 and a profile assembly and float that support the solar panel 210 so that it is positioned on the water surface. The main components of the support member include a lower fixing part 110, a tilt support part 120, a rear end support part 130, and a space member 150. The present invention is configured to allow the solar panel 210 to be easily and stably supported in a fixed position by a combination of these main components, and to allow the support angle of the solar panel 210 to be easily changed according to the latitude of the installation site.

[0031] The following will provide a detailed description of the solar panel tilt support member 100 according to the embodiment of the present invention, focusing on each of the above-mentioned components.

[0032] The lower fixing portion 110 is formed to be long in the front-rear direction and is fixed to the vertical horizontal frame 220 and the lateral horizontal frame of the profile assembly, playing a role in supporting the inclined support portion 120 and the rear end support portion 130 from below. Because the lower fixing portion 110 is formed to be long in the front-rear direction, it is more preferable, as shown in Figure 4, to fix it in a manner that is in contact with the vertical horizontal frame 220 rather than fixing it in a manner that intersects with the lateral horizontal frame of the profile assembly, as this provides greater stability and strength.

[0033] As shown in Figures 2 and 3, the lower fixing portion 110 further has fastening panel portions 140 that extend downward in pairs at the lower ends of the left and right sides of the profile assembly, and can contact the left and right sides of the vertical horizontal frame 220. Fastening holes 141 are formed in the fastening panel portions 140 for fastening bolts to the vertical horizontal frame 220. Multiple fastening panel portions 140 are arranged at intervals along the length of the lower fixing portion 110. When a pair of fastening panel portions 140 are formed on the left and right sides of the lower fixing portion 110 in this way, there is an advantage that the lower fixing portion 110 can be securely attached to the vertical horizontal frame 220 of the profile assembly without misalignment using the fastening panel portions 140. Subsequently, by fastening the fastening panel portions 140 and the vertical horizontal frame 220 with bolts via the fastening holes 141, the lower fixing portion 110 is stably fixed in a state supported by the vertical horizontal frame 220.

[0034] Here, the outer surface of the fastening panel portion 140 is provided with a plurality of second reinforcing ribs 140a that protrude vertically. This reinforces the relatively thin fastening panel portion 140 so that it does not easily bend or break even if it is pressed or impacted by the vertical horizontal frame 220 during the process of fastening the lower fixing portion 110 to the vertical horizontal frame 220.

[0035] The inclined support portion 120 plays a substantial role in supporting the solar cell panel 210 at an angle, and has a shape that branches off from the front end of the lower fixing portion 110 and extends long, inclined upward and backward. The inclined support portion 120 intersects and supports the upper lateral support frame 211a, which supports the upper end of the solar cell panel 210 from below, and the lower lateral support frame 211b, which supports the lower end of the solar cell panel 210 from below, at the bottom. The inclined support portion 120 is formed to extend further rearward after passing the point where the rear end support portion 130 joins it, and has a lower bolt hole 121b near the rear side from the point where it branches off from the lower fixing portion 110, and the lower bolt 212b is fastened to the lower lateral support frame 211b with the lower bolt hole 121b passing through it, and has an upper bolt hole 121a at the rear end that extends from the point where the rear end support portion 130 joins it, and the upper bolt 212a is fastened to the upper lateral support frame 211a with the upper bolt hole 121a passing through it.

[0036] Here, it is noteworthy that the upper bolt hole 121a of the inclined support portion 120 is formed as an elongated hole, with a wider inner diameter in the front-to-back direction than in the left-to-right direction, as shown in Figure 7. This is to allow for changes in the angle of the upper bolt 212a that occur when changing the installation height of the upper lateral support frame 211a supporting the solar cell panel 210, in order to change the inclination angle of the solar cell panel 210 so that it can generate power effectively according to the latitude of the installation site of the floating solar power generation device, as shown in the enlarged sections of Figures 2, 5, and 8, respectively. For reference, Figures 2 through 5 and 8 show that the inclination angle of the solar cell panel 210 increases from Figure 2, and as the inclination angle of the solar cell panel 210 changes in this way, the angle of the upper bolt 212a also inevitably changes.

[0037] The rear end support portion 130 plays a role in stably supporting the rear end of the inclined support portion 120. For this purpose, the rear end support portion 130 branches off from the rear end of the lower fixing portion 110 and extends upward for a long distance, and then its upper end merges with the inclined support portion 120, becoming one with the inclined support portion 120. The rear end support portion 130, together with the lower fixing portion 110 and the inclined support portion 120, forms a structurally very stable triangular structure. At this time, the rear end support portion 130 is integrated with the inclined support portion 120 in a shape that is perpendicular or nearly perpendicular to it.

[0038] The lower fixing portion 110, the inclined support portion 120, and the rear end support portion 130 described above are all constructed based on a body formed integrally from a vertical panel portion 100a, a first horizontal panel portion 100b, a second horizontal panel portion 100c, and first reinforcing ribs 100d and 100e, as shown in the enlarged view of Figure 3. The vertical panel portion 100a is formed vertically in a flat plate shape. The first horizontal panel portion 100b is formed horizontally along one end of the vertical panel portion 100a and forms a T-shaped cross-section with the vertical panel portion 100a. The second horizontal panel portion 100c is formed horizontally along the other end of the vertical panel portion 100a and forms an inverted T-shaped cross-section with the vertical panel portion 100a. The first reinforcing ribs 100d and 100e protrude from the left and right sides of the vertical panel section 100a, respectively, with one end and the other end joined to the first horizontal panel section 100b and the second horizontal panel section 100c, respectively, and serve to reinforce the strength so that the first horizontal panel section 100b and the second horizontal panel section 100c do not deform. For this purpose, the first reinforcing ribs 100d and 100e consist of a straight vertical rib 100d that connects the first horizontal panel section 100b and the second horizontal panel section 100c orthogonally, and an X-shaped inclined rib 100e that connects the first horizontal panel section 100b and the second horizontal panel section 100c in an X shape. In the case of the linear vertical rib 100d, it is effective in preventing deformation that may occur when a load is applied in the vertical direction between the first horizontal panel section 100b and the second horizontal panel section 100c, and the X-shaped inclined rib 100e is effective in preventing deformation that may occur when a load is applied in the inclined direction between the first horizontal panel section 100b and the second horizontal panel section 100c.

[0039] The lower fixing portion 110, the inclined support portion 120, and the rear end support portion 130 are made of synthetic resin, which is a lightweight material that is more advantageous to mold than metal and allows for minimizing weight. Furthermore, in terms of form, the body consisting of the vertical panel portion 100a, the first horizontal panel portion 100b, the second horizontal panel portion 100c, and the first reinforcing ribs 100d and 100e ensures sufficient strength to support the solar cell panel 210 while remaining lightweight.

[0040] As shown in Figure 4, the solar cell panel tilt support members according to an embodiment of the present invention are provided in pairs on both the left and right sides, spaced apart from each other, and can support the upper lateral support frame 211a and the lower lateral support frame 211b that support the solar cell panel 210.

[0041] As shown in Figures 5 to 7, the space member 150 is included separately from the integrally molded lower fixing portion 110, inclined support portion 120, and rear end support portion 130, and plays a role in further increasing the inclination angle of the solar cell panel 210 by separating the upper lateral support frame 211a upward from the inclined support portion 120. The space member 150 is located between the inclined support portion 120 and the upper lateral support frame 211a, and consists of a lower support portion 150a that is inserted and supported on the outside of the inclined support portion 120, separating the upper lateral support frame 211a upward from the inclined support portion 120, and an upper separation portion 150b that is formed in a shape extending upward from the lower support portion 150a and supports the upper lateral support frame 211a between the inclined support portion 120 and the upper lateral support frame 211a, separating it from the inclined support portion 120.

[0042] As shown in Figure 6, the lower support portion 150a of the space member 150 consists of a pair of lower side walls 151 that are in close contact with the left and right sides of the inclined support portion 120, and a lower ceiling 152 that connects the upper ends of the pair of lower side walls 151 and is in contact with the upper surface of the inclined support portion 120. The upper separation portion 150b consists of a pair of upper side walls 153 that extend upward from the lower side walls 151, and an upper ceiling 154 that connects the upper ends of the pair of upper side walls 153 and is in contact with the lower surface of the upper lateral support frame 211a. The lower ceiling 152 of the lower support portion 150a and the upper ceiling 154 of the upper separation portion 150b each have through holes 154a that are in communication with each other, corresponding to the upper bolt holes 121a of the inclined support portion 120, through which the upper bolts 212a pass.

[0043] Furthermore, the upper separation portion 150b of the space member 150 further includes a guide pipe 156 that connects the through hole 154a in the lower ceiling 152 and the through hole 154a in the upper ceiling 154 to guide the upper bolt 212a. With the guide pipe 156 further formed, the upper bolt 212a can be passed through the through hole 154a formed in the lower ceiling 152 of the lower support portion 150a and the upper ceiling 154 of the upper separation portion 150b smoothly without any hindrance. In addition, multiple vertical plate-shaped reinforcing wing portions 157 are arranged along the circumferential direction of the guide pipe 156, projecting radially from the outer surface of the guide pipe 156, with their upper and lower ends in contact with and integrated with the lower ceiling 152 and the upper ceiling 154. In this way, the space member 150, with its configuration including the guide pipe 156 and the reinforcing wing portions 157, can have high strength despite being a lightweight member made of synthetic resin.

[0044] On the other hand, at the lower ends of the pair of lower side walls 151 belonging to the lower support portion 150a of the space member 150, detachment prevention protrusions 151a are further formed, which are bent in opposing directions and engage with the lower surface of the inclined support portion 120. In this way, with the detachment prevention protrusions 151a, it is possible to prevent the space member 150 from detaching upward while it is coupled to the inclined support portion 120. Furthermore, by slightly widening the pair of lower side walls 151, which are made of an elastic synthetic resin, the lower support portion 150a can be easily fitted onto the inclined support portion 120.

[0045] Preferably, the space member 150 is provided in two or more types with different heights of the upper separation portion 150b so that the tilt angle of the solar cell panel 210 can be changed, and can be selectively installed on the tilt support portion 120. This makes it possible to support the solar cell panel 210 with its tilt angle adjusted as needed, as shown in Figure 2 without using the space member 150, and in Figures 5 and 8 with the space member 150. Figures 8 and 9 show a space member 150 with a relatively higher upper separation portion 150b compared to the space member 150 shown in Figures 5 to 7. As the height of the upper separation portion 150b of the space member 150 increases, the vertical length of the guide pipe 156 and the vertical length of the reinforcing wing portion 157 also increases. Therefore, it is preferable to further form an intermediate reinforcing portion 158 in the shape of a horizontal panel, which is integrated so that the guide pipe 156 and the reinforcing wing portion 157 intersect and contact at an intermediate point between the lower ceiling 152 and the upper ceiling 154.

[0046] As described above, with the configuration including the space member 150, the tilt angle of the solar panel 210 can be easily changed according to the latitude of the installation location simply by inserting the space member 150 into the tilt support part 120. [Modes for carrying out the invention]

[0047] Next, a modified embodiment of the solar panel tilt support member of the present invention will be described below.

[0048] Figure 10 is a perspective view of a solar panel tilt support member according to a modified embodiment of the present invention, and Figure 11 is a side view of the solar panel tilt support member according to a modified embodiment of the present invention.

[0049] As shown in the figure, the solar panel tilt support member according to a modified embodiment of the present invention is characterized in that, unlike the original embodiment, it can support the upper lateral support frame 211a in response to a change in the tilt angle of the solar panel 210 without providing a separate space member 150.

[0050] Therefore, to allow the upper lateral support frame 211a to be selectively supported at different heights, stepped sections 120a and 120b are formed at the rear end of the inclined support section 120 in an ascending staircase shape that becomes higher towards the rear. Upper additional bolt holes 121a-2 and 121a-3 are further formed at each stepped section 120a and 120b so that the upper bolt 212a can pass through them, and corresponding to the upper additional bolt holes 121a-2 and 121a-3, a plurality of lower additional bolt holes 121b-2 and 121b-3 are further formed at the front end of the inclined support section 120.

[0051] Here, the upper surfaces of the stepped portions 120a and 120b are formed as surfaces that are steeper inclined than the upper surface of the inclined support portion 120. When multiple stepped portions 120a and 120b are formed, the surfaces formed further back are steeper inclined than those formed further forward, thereby accommodating the changed inclination angle of the solar cell panel 210.

[0052] While preferred embodiments of the present invention have been described above, various variations, modifications, and equivalents can be used. It is clear that the present invention can be similarly applied by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the present invention as determined by the following limitations of the claims. [Explanation of symbols]
