Description

[Technical Field]

[0001] The present invention relates to a floating platform and a solar power generation system. [Background technology]

[0002] In general, floating marine solar power generation systems, in contrast to land or freshwater systems, have the advantages of being suitable for deep water, not affected by the ground, being portable and reusable, being relatively economical, being quick to install, and having low construction costs depending on the water depth.

[0003] However, unlike freshwater environments, the durability of floating marine solar power generation systems is significantly affected by the sea level of the ocean area where they are installed, so wave direction, wave height, and ocean currents must be taken into consideration when determining the installation location and direction.

[0004] This is because in a saline marine environment, the floating offshore solar power generation system can move in the direction of the ocean current in response to the flow of the ocean current, and the accompanying wave energy causes the floating offshore solar power generation system to move up and down, making it prone to wave resonance in the up and down piston mode that occurs with each up and down movement.

[0005] Therefore, the durability of floating marine solar power generation systems is more important in the marine environment. Here, durability means static safety against external forces and dynamic safety against moments that induce motion.

[0006] In the marine environment, disturbances such as ocean currents (below the sea surface), waves (on the sea surface), and sea breezes (above the sea surface) occur periodically in one or more directions with different magnitudes.

[0007] Looking at the factors that affect the durability of a floating offshore solar power generation system in the offshore environment, as shown in Figure 1, the floating platform 30A is forced to undergo six degrees of freedom of movement, namely, slippage (lateral force from side to side: FS, longitudinal drag force: FD), lift (lift force: FL), vertical oscillation in the direction of ocean currents (MP), horizontal oscillation in the direction of ocean currents (MR), and rotation perpendicular to the sea surface (MY).

[0008] At this time, the length and holding force of the mooring cable according to the water depth have structural and economic limits, so the forced six-degree-of-freedom movement of the floating platform 30A gradually accumulates fatigue loads on the mooring of the floating offshore solar power generation system or the connection between the floating platform 30A and the structure 40A.

[0009] In FIG. 1, the floating body unit pontoons 20A and the floating body platform 30A are structures that connect a plurality of floating bodies 10A and function to support the structure 40A below the structure 40A that supports the solar panel module 50A.

[0010] Therefore, the floating platform 30A of the floating offshore solar power generation system must be able to suppress the six-degree-of-freedom forced motions to reduce fatigue loads on the connections of the mooring devices or structures 40A.

[0011] Furthermore, in a typical solar power generation device, the power generation capacity varies depending on the power generation area and the amount of sunlight.

[0012] Due to the characteristics of floating offshore solar power generation systems, which are installed over a wide area of ​​the ocean, which receives more sunlight than land and is relatively open, there are localized differences in external forces surrounding the wide floating platform due to tidal phenomena (high tide and low tide that occur twice a day), which reduces the durability of parts of the floating platform.

[0013] Therefore, the entire floating platform of a floating offshore solar power generation system must be able to suppress six-degree-of-freedom forced motion due to external forces, and the floating pontoons, which are the unit modules that make up the floating platform, must also be able to withstand differences in local external forces in order to prevent a decrease in local durability.

[0014] In addition, the power generation capacity of a floating offshore solar power generation system increases as the number of solar panel modules included in the installation area increases. Since the installation area depends on the shape of the floating platform, it is effective and cost-effective to design the shape of the floating platform to fit the given offshore area as closely as possible without excess area.

[0015] Therefore, there is a need for a floating platform shape design technology that can approximate the installation area of ​​a floating offshore solar power generation system to a given offshore area.

[0016] In addition, because an offshore solar power generation system requires a structure with solar panel modules to always float on the sea surface, if the floating platform sways a lot on the roiling waters caused by wind and waves, the solar panel modules also sway a lot, hindering smooth solar power generation.

[0017] In conclusion, in order to economically ensure the uniform power generation capacity of a floating marine solar power generation system, technology is required to realize a robust floating platform that can always float stably on the water, even when the water is turbulent due to wind and waves, and that can approximate a given sea area. Summary of the Invention [Problem to be solved by the invention]

[0018] The present invention provides a floating platform and a solar power generation system that can efficiently disperse the impact energy of waves and can always float stably on the water even if there are shifts and movements caused by swells, sea breezes, ocean currents, etc., and can be realized in a manner that approximates a given sea surface area. [Means for solving the problem]

[0019] A floating body platform according to one embodiment of the present invention includes a plurality of socket frames on which floating bodies are mounted, and a plurality of connecting frames that connect the plurality of socket frames, and the plurality of socket frames and the plurality of connecting frames can be connected to each other to form a plurality of floating body unit groups with a hexagonal truss structure.

[0030] The plurality of first auxiliary socket portions and the plurality of second auxiliary socket portions may include an inverted trapezoidal cross section.

[0031] The number of floating bodies (NN) of the floating body platform is set to satisfy the following formula (1): Number of floating bodies (NN) = 3 × n × (n-1) + 1 --- Formula (1) Here, n indicates the number of floating bodies arranged in Lc, and Lc can indicate the length of one side of a regular hexagon inscribed in the installation area that forms a virtual circle.

[0038] In addition, a zigzag flow can be generated inside the floating platform, which is installed over a wide area, allowing for the passage of ocean currents.

[0039] In addition, it not only allows the wave impact energy to be efficiently distributed to adjacent unit pontoons, but also has the economic effect of minimizing the number of floating unit pontoons and maximizing the usable area of ​​the sea surface. [Brief explanation of the drawings]

Predefined terms are additionally interpreted to have a meaning consistent with the relevant technical literature and the presently disclosed content, and are not interpreted in an ideal or very formal sense unless otherwise defined.

[0044] FIG. 2 is a schematic perspective view of a floating platform of a solar power generation system according to an embodiment of the present invention, and FIG. 3 is a schematic plan view showing an installation structure of the floating platform of the solar power generation system according to an embodiment of the present invention.

[0045] FIG. 4 is a schematic perspective view for explaining a state in which a solar power generation system according to an embodiment of the present invention is mounted on a floating platform.

[0046] Referring to Figures 2 to 4, a floating body platform according to one embodiment of the present invention may include a plurality of socket frames 100 on which floating bodies 11 are mounted, and a plurality of connection frames 200 that connect the plurality of socket frames 100.

[0047] A plurality of socket frames 100 and a plurality of connection frames 200 can be connected to each other to form a plurality of floating body unit groups 10 having a hexagonal truss structure.

[0048] The plurality of socket frames 100 and the plurality of connection frames 200 may be fastened together by welding, bolting, or the like.

[0049] The socket frame 100 may also include a plurality of socket portions 110 arranged radially around the central portion O1.

[0050] Each of the plurality of sockets 110 forms a set angle θ with the adjacent sockets 110, and the angle may be, for example, 60°, to form a group of float units 10 having a hexagonal truss structure.

[0051] The plurality of connection frames 200 are inserted and connected to the plurality of socket parts 110, The plurality of connection frames 200 may form a set angle, for example, 60°, with the adjacent connection frames 200 .

[0052] The socket portion 110 may be formed of a hollow tube with an open interior for insertion and connection of the connection frame 200 .

[0053] In addition, since the connection frame 200 is inserted into the socket part 110 , the connection frame 200 may have the same cross-sectional shape as the cross-sectional shape of the socket part 110 .

[0054] Additionally, the linkage frame 200 may be hollow tubular or the like with an open interior to minimize weight.

[0055] The plurality of socket frames 100 and the plurality of connecting frames 200 may include an inverted trapezoidal cross section.

[0056] In this way, since the multiple socket frames 100 and the multiple connecting frames 200 have an inverted trapezoidal cross section, when the sea breeze blows, the amount of lift of the connecting frame 200 (the amount of movement of the center line in the vertical direction of sea level) is reduced, reducing the stress generated in the connecting frame 200 and the socket frame 100 and ensuring a stable connecting force.

[0057] The plurality of socket parts 110 may include a plurality of first socket parts 111 to which six connection frames 200 are connected, a plurality of second socket parts 112 to which four connection frames 200 are connected, and a plurality of third socket parts 113 to which three connection frames 200 are connected.

[0058] A plurality of auxiliary socket frames 300 may be included, which are arranged within the group of float units 10 .

[0059] The plurality of auxiliary socket frames 300 may not be provided with floating bodies 11 .

[0060] The plurality of auxiliary socket frames 300 may include a plurality of first auxiliary socket units 310 to which four connection frames 200 are connected, and a plurality of second auxiliary socket units 320 to which three connection frames 200 are connected.

[0061] The first auxiliary socket portions 310 and the second auxiliary socket portions 320 may be hollow tubular with an empty interior for insertion and connection of the connection frame 200 .

[0062] The plurality of first auxiliary socket portions 310 and the plurality of second auxiliary socket portions 320 may include an inverted trapezoidal cross section.

[0063] In addition, the upper portions of the multiple socket frames 100 may have connecting holes 101 into which the structural body 20 supporting the solar panel modules 30 can be inserted and connected, or the structural body 20 may be connected to the socket frame 100 by bolting or welding without processing the connecting holes 101.

[0064] A walkway or step 40 may be provided on the top of the socket frame 100 and the connecting frame 200 for maintenance, safety inspection, etc.

[0065] The number (NN) of floating bodies 11 of the floating body platform may be set to satisfy the following formula (1). Number of floating bodies (NN) = 3 × n × (n-1) + 1 --- Formula (1) Here, n indicates the number of floating bodies arranged in Lc, and Lc can indicate the length of one side of a regular hexagon inscribed in the installation area that forms a virtual circle.

[0066] Furthermore, the length (Lp) of the connection frame 200 of the floating body platform may be set to satisfy the following formula (2). Length of the connected frame (Lp) = Lc / (n-1) --- Equation (2)

[0067] The number (NL) of floating bodies 11 arranged within the horizontal or vertical width of the floating body platform may be set to satisfy the following formula (3). Number of floating bodies (NL) = 2 × (n-1) --- Equation (3)

[0068] Furthermore, the number (NP) of the floating body unit groups 10 of the floating body platform may be set so as to satisfy the following formula (4). Number of floating unit groups (NP) = 3 / 4 × n × (n-2) + 1 --- Equation (4)

[0069] The number of triangles (S) of the floating body platform may be set to satisfy the following equation (5): The number of triangles on the floating platform (S) = 6 × (n-1) × (n-1) --- Equation (5)

[0070] On the other hand, compared to freshwater, the area given to the sea is relatively large, there are fewer interferences, and there is a high degree of freedom.

[0071] Therefore, in the present invention, as an example, a method for approximating the installation area occupied by a floating platform and the offshore area, assuming that the offshore area where the floating power generation system is located is a circle, will be described with reference to Figure 7.

[0072] Typically, the number (NB) and equivalent diameter (DE) of floating bodies supporting a floating body platform are determined by the force in the direction of gravity (weight of solar panels, solar panel module support structure, floating body platform, floating bodies, etc.) and the force in the opposite direction to gravity (buoyancy depending on the shape of the floating bodies and the immersion rate of the floating bodies).

[0073] Since the float unit group 10 of the present invention has floats at seven nodes, the total number of floats (NB) supporting the float platform is the same as the total number of nodes (NN) included in the float platform shown in Figure 7, as shown in the following equation (6). NN=NB ---Equation (6)

[0074] Assuming that the number of nodes (number of floating bodies) included in one side of a regular hexagon inscribed in a circular offshore area is n, the total number of nodes (NN) included in the floating body platform may be set to satisfy the following equation (7). NN=3×n×(n-1)+1 ---Equation (7) Here, n is always an even number.

[0075] In Figure 7, the total number of floating bodies is 37, and n is 4.

[0076] In this case, the length (Lp) of the connecting frame 200 and the side length (Lc) of the floating body platform may be set to satisfy the following equations (8) and (9), where RC is the radius of the floating body platform. Lc=2×RC×sin30=RC ---Equation (8) Lp = Lc / (n-1) --- Equation (9)

[0077] Furthermore, since the floating body platform is a regular hexagon, the number of horizontal rows (NL) may be set to satisfy the following equation (10). NL=2×n-1 ---Equation (10)

[0078] As an example, in FIG.

[0079] At this time, the actual total number (NP) of the float unit groups 10 may be set to satisfy the following equation (11). NP=3 / 4×n×(n-2)+1 ---Equation (11)

[0080] As an example, in FIG.

[0081] The number (S) of triangles forming a truss in the floating body platform may be set to satisfy the following equation (12). S = 6 × (n-1) × (n-1) --- Equation (12)

[0082] As an example, in FIG.

[0083] The installation area can be satisfied by the following formula (13). A0=π×RC×RC ---Equation (13)

[0084] The power generating area occupied by the floating body is calculated using the following formula (14). AB=3×Lc×Lc×cos30 ---Equation (14)

[0085] Therefore, the ratio of the power generation area to the installation area can be calculated using the following formula (15). AB / A0=82.7% ---Equation (15)

[0086] FIG. 8 shows a floating platform according to the present invention circumscribed in a circular sea area having a radius (RC).

[0087] Unlike the floating body platform inscribed in a circle, the length (Lp) of the connection frame 200 and the side length (Lc) of the floating body platform may be set to satisfy the following equation (16). Lc=2×RC×tan30 ---Equation (16)

[0088] Therefore, in this case, the ratio of the power generation area to the installation area can be calculated using the following formula (17). AB / A0=110.3% ---Equation (17)

[0089] Furthermore, a solar power generation system according to an embodiment of the present invention may include the floating platform described above.

[0090] Hereinafter, the operation of the floating body platform according to one embodiment of the present invention will be described with reference to FIGS.

[0091] The floating body platform of the present invention includes a plurality of socket frames 100 on which floating bodies 11 are mounted, and a plurality of connecting frames 200 that connect the plurality of socket frames 100, and the plurality of socket frames 100 and the plurality of connecting frames 200 are connected to each other to form a plurality of floating body unit groups 10 having a hexagonal truss structure.

[0092] Therefore, even if the whole or part of the floating marine solar power generation system frequently moves back and forth / left and right / up and down (translational movement) or sways (rotational movement) due to large physical energy fluctuations in ocean currents caused by sea breezes including typhoons and tidal phenomena, it is possible to minimize the reduction in durability and lifespan, and the generation of zigzag throughflows facilitates the passage of ocean currents.

[0093] In addition, since the floating body unit group 10 has a hexagonal truss structure, the impact energy of waves can be efficiently dispersed to the adjacent floating body unit groups 10.

[0094] Furthermore, by stacking the floating body unit groups 10 using a plurality of socket frames 100 and a plurality of connecting frames 200 to make the entire system function as a single structure, durability and impact resistance can be improved, and installation costs can be reduced by increasing the offshore area installation efficiency.

[0095] In addition, the floating body unit group 10 having a hexagonal truss structure has a low possibility of generating shock waves regardless of the direction of the ocean current, and can minimize vortex areas where tidal current stagnation occurs.

[0096] In particular, the floating body unit group 10 with a hexagonal truss structure can be integrally superimposed (connected) with a plurality of socket frames 100 and a plurality of connecting frames 200 each having an inverted trapezoidal cross section, thereby generating lift that pushes the floating body platform in the direction of gravity so that the strength of the sea breeze can be increased, thereby stabilizing the floating body platform.

[0097] Furthermore, since the multiple socket frames 100 and the multiple connecting frames 200 have an inverted trapezoidal cross section, when the sea breeze blows, the amount of lift of the connecting frame 200 (the amount of movement of the center line in the vertical direction of sea level) is reduced, reducing the stress generated in the connecting frame 200 and the socket frame 100 and ensuring a stable connecting force.

[0098] Furthermore, since a plurality of auxiliary socket frames 300 are provided within the float unit group 10, the rigidity of the float platform can be increased accordingly.

[0099] Referring to Figure 5(a), the floating body unit group 10 of the floating body platform is composed of floating bodies 11 having a set diameter fastened to the vertices and center point of a hexagon, and has seven nodes (hereinafter referred to as the "basic type 10b").

[0100] Referring to Figure 5(b), the floating body unit group 10 of the floating body platform has 13 nodes, consisting of two hexagonal truss structures and one central point, when further structural stability is required (hereinafter referred to as "reinforced 10s").

[0101] Here, to form an internal hexagonal truss structure, a connecting frame 200 connected to a socket frame 100 located at the center point is inserted into and coupled with an auxiliary socket frame 300. At this time, if additional buoyancy of the floating body unit group 10 is required, floating bodies 11 may be provided at each node of the internal small hexagon.

[0102] FIG. 6 shows a hybrid structure that combines the basic floating platform 10b of FIG. 5(a) and the reinforced floating platform 10s of FIG. 5(b).

[0103] In the case of such a mixed type floating platform, when the installation area is subject to large external forces such as ocean currents, waves, and sea breezes, the reinforced type 10s is positioned at the location where the impact of the external forces is greatest, and floating platforms 10s' with reduced numbers of nodes of the reinforced type 10s are arranged around it, and then floating platforms of the basic type 10b are arranged.

[0104] At this time, in order to strengthen the fastening force between the floating bodies 11 and maintain structural stability, a connecting frame 200' can be added to two adjacent socket frames 100 between the floating body unit groups 10 to form a new floating body unit group 10 (shown by dotted lines).

[0105] As described above, it can be seen that the structural reinforcement of the float unit group 10 and the float platform according to the present invention can be realized by simply connecting the socket frame 100 and the connecting frames 200, 200'.

[0106] In addition, the floating body platform of the present invention has a doubly symmetrical structure for six-degree-of-freedom forced motion, and in order to enable efficient distribution, the floating body unit groups 10 are arranged in a regular hexagon using a plurality of socket frames 100, a plurality of connecting frames 200, etc., without any separate fastening means between the floating body unit groups.

[0107] This allows the buffering action between the geometrically overlapping floating body unit groups 10 to damp the shifts and oscillations of the floating marine solar power generation system and reduce fluctuations in the tilt angle of the solar panel modules due to waves and ocean currents.

[0108] Figures 9 to 11 show a comparison of the installation area and power generation area of ​​a preferred embodiment of the present invention with a comparative example when the area occupied by one floating platform is the same regardless of the shape of the floating platform.

[0109] In the comparative examples, the position of the floating body varies and it is not located at the node of the floating body platform as in the present invention, but for the sake of comparison, it is assumed that the floating body is located at the node of the floating body platform as in the present invention, and it is assumed that the floating body platform area is included in more than 50% of the sea surface area so as to approximate the sea surface area as much as possible.

[0110] As shown in Figure 9, in the case of the rectangular floating platform of the comparative example, it can be seen that there is asymmetry depending on the direction of the installation area, and the total number of floating unit pontoons that make up the floating platform is 12, and the total number of floating bodies is 20.

[0111] In addition, when the hexagonal float unit pontoons of the comparative example shown in Figure 10 are arranged arbitrarily, there is asymmetry depending on the direction of the installation area, similar to Figure 9, and the total number of float unit pontoons is 10 and the total number of floats is 32.

[0112] However, in the case of the floating platform of the embodiment of the present invention as shown in FIG. 11, symmetry is maintained regardless of the direction of the installation area, and the total number of unit pontoons is 7 and the total number of floating bodies is 37.

[0113] Therefore, in the case of the embodiment of the present invention, it is possible to increase the number of floating bodies that provide buoyancy while decreasing the number of unit pontoons.

[0114] In addition, the floating body unit pontoons share overlapping nodes with each other.

[0115] In particular, in the case of the floating body unit pontoon 4 located in the center of the floating body platform in FIG. 11, it can be seen that one floating body is located at the central node and can be easily manufactured with one floating body socket frame 100 and connecting frame 200.

[0116] In addition, the durability of the floating platform is further increased by the unit pontoons (as an example, the shaded area between pontoons number 2 and pontoon number 5) that are naturally geometrically generated by simply connecting the floating unit pontoons arranged along the sides of the hexagon with the connecting frame 200.

[0117] In other words, in the case of the first row in the upper horizontal direction, although there are actually two floating body unit pontoons along one side, geometrically it is the same as three floating body unit pontoons overlapping each other.

[0118] Figure 12 shows an embodiment of the present invention, in which when a plurality of honeycomb float unit pontoons are configured as a float platform arranged in a regular hexagon, the number of float unit pontoons present inside the float platform, including overlaps, is shown, based on the actual unit pontoons required to be installed according to the number of floats and the geometric unit pontoons generated by connecting adjacent float unit pontoons using only a connecting frame.

[0119] As the number of floating bodies increases, i.e., the installation area becomes larger, the number of geometric unit pontoons increases rapidly, which is more economical, while strengthening the cohesion between the unit pontoons to prevent them from separating, thereby improving durability and impact resistance to fluidly respond to waves and swells.

[0120] Furthermore, when the circumscribing hexagonal floating platform of the present invention is used, the installation area (utilizable area) can completely occupy the sea area, as shown in FIG.

[0121] Although the present disclosure has been described through the above preferred embodiments, the present invention is not limited thereto, and it will be readily understood by those skilled in the art to which the present invention pertains that various modifications and variations are possible without departing from the scope of the claims set forth below.
