Description

Technical Field

[0001] The present invention relates to a floating body platform and a photovoltaic power generation system. Background Art

[0002] Generally speaking, compared with land or freshwater systems, floating offshore photovoltaic power generation systems are suitable for deep waters, are not affected by the ground, can be moved and reused, are relatively cost-effective, and can be set up quickly, thus having the advantage of lower construction costs according to water depth.

[0003] However, different from the freshwater environment, the durability of floating offshore photovoltaic power generation systems is greatly related to the sea level of the sea area where they are set up. Therefore, when determining the setting position and direction, wave direction (wave direction), wave height (wave height), and ocean current, etc. must be further considered.

[0004] This is because, in a saline marine environment, as the ocean current flows, the floating offshore photovoltaic power generation system moves along the direction of the ocean current, and the wave energy of the accompanying waves causes the floating offshore photovoltaic power generation system to move up and down, and the floating offshore photovoltaic power generation system is prone to wave resonance in the up-and-down piston mode that occurs every time it moves up and down.

[0005] Therefore, for the durability of floating offshore photovoltaic power generation systems, higher requirements are imposed in the marine environment. Durability refers to static safety against external forces and dynamic safety against moments causing sway.

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

[0007] In the marine environment, the reasons affecting the durability of floating offshore photovoltaic power generation systems are as follows: As Figure 1 shown, the floating body platform 30A is forced to bear six degrees of freedom of movement such as pushing (lateral force left and right: FS, front and rear resistance: FD), lifting (lifting force: FL), up and down swing in the direction of the ocean current (MP), left and right swing in the direction of the ocean current (MR), or rotation in the vertical direction of the sea surface (MY), etc.

[0008] At this time, due to structural and economic limitations in the length and gripping force of the mooring device cables according to water depth, the six degrees of freedom forced movement of the floating body platform 30A will cause gradual accumulation of fatigue loads on the mooring device of the floating offshore photovoltaic power generation system or the connection part between the floating body platform 30A and the structure 40A.

[0009] In Figure 1 the floating body unit pontoons 20A and the floating body platform 30A are structures connecting multiple floating bodies 10A, and their function is to support the structure 40A below the structure 40A that supports the photovoltaic panel module 50A.

[0010] Therefore, the floating body platform 30A of the floating offshore photovoltaic power generation system must be able to suppress forced motion in six degrees of freedom to reduce the fatigue load on the connection part of the mooring device or the structure 40A.

[0011] In addition, for conventional photovoltaic power generation equipment, there are differences in power generation capacity according to the power generation area and the amount of sunlight.

[0012] Compared with land, the floating offshore photovoltaic power generation system is installed in a large area of sea with sufficient sunlight and relatively open space. Due to the above characteristics of the floating offshore photovoltaic power generation system, according to the tidal phenomenon (high tide and low tide occurring twice a day), there are local differences in the external forces around the broad floating body platform, so the durability of some parts of the floating body platform is poor.

[0013] Therefore, the entire floating body platform of the floating offshore photovoltaic power generation system must be able to suppress forced motion in six degrees of freedom under the action of external forces, and the unit module floating pontoons that make up the floating body platform must also be able to resist local external force differences to avoid local durability degradation.

[0014] In addition, as the number of photovoltaic panel modules in the installation area increases, the power generation capacity of the floating offshore photovoltaic power generation system will increase. The installation area depends on the shape of the floating body platform. Therefore, the shape of the floating body platform should be designed to be as close as possible to the specified sea area without redundant areas, which is beneficial in terms of efficiency or cost.

[0015] Therefore, a technology for designing the shape of the floating body platform is required to make the installation area of the floating offshore photovoltaic power generation system approximate to the specified sea area.

[0016] In addition, for the offshore photovoltaic power generation system, the structure with photovoltaic panel modules must always float on the sea surface. Therefore, when the floating body platform swings violently on the water surface due to wind and waves, the photovoltaic panel modules will also swing violently, resulting in the problem that photovoltaic power generation cannot proceed smoothly.

[0017] In summary, in order to economically ensure the uniform power generation capacity of the floating offshore photovoltaic power generation system, a technology is required to achieve a sturdy floating body platform by making the area approximate to the specified sea area, so that it can always float stably on the water surface even in rough seas. Summary of the Invention

[0063] Figure 2 is a three-dimensional schematic diagram of a floating platform of a photovoltaic power generation system according to an embodiment of the present invention. Figure 3 is a top view schematic diagram showing the installation structure of a floating platform of a photovoltaic power generation system according to an embodiment of the present invention.

[0064] Figure 4 is a three-dimensional schematic diagram for explaining the installation state of a floating platform of a photovoltaic power generation system according to an embodiment of the present invention.

[0065] Referring to Figures 2 to 4 , the floating platform according to an embodiment of the present invention may include: a plurality of socket frames 100 for setting the floating body 11; a plurality of connecting frames 200 for connecting the plurality of socket frames 100.

[0066] The plurality of socket frames 100 and the plurality of connecting frames 200 may be connected to each other to form a plurality of floating body unit groups 10 of hexagonal truss structures.

[0067] The connection of the plurality of socket frames 100 and the plurality of connecting frames 200 may be achieved by welding connection or bolt connection, etc.

[0068] In addition, the socket frame 100 may include a plurality of socket portions 110 arranged radially around the central portion O1.

[0069] Each of the plurality of socket portions 110 forms a set angle (θ) with an adjacent socket portion 110, for example, may form a 60-degree angle, so as to form a floating body unit group 10 of hexagonal truss structures.

[0070] The plurality of connecting frames 200 are inserted into the plurality of socket portions 110.

[0071] The plurality of connecting frames 200 form a set angle with an adjacent connecting frame 200, for example, may form a 60-degree angle.

[0072] The socket part 110 can be formed into a hollow tubular shape with a hollow interior or the like for the insertion connection of the connection frame 200.

[0073] In addition, the connection frame 200 can have the same cross-sectional shape as that of the socket part 110 so as to be inserted into the socket part 110.

[0074] In addition, the connection frame 200 can be formed into a hollow tubular shape with a hollow interior or the like to minimize the weight.

[0075] The plurality of socket frames 100 and the plurality of connection frames 200 can include a trapezoidal cross-section.

[0076] In this way, the plurality of socket frames 100 and the plurality of connection frames 200 have a trapezoidal cross-section, so that when the sea breeze blows, the lifting amount of the connection frame 200 (the change amount in the vertical direction of the sea surface of the center line) will be reduced, thus reducing the stress generated on the connection frame 200 and the socket frame 100, and a stable bonding force can be ensured.

[0077] The plurality of socket parts 110 can include: a plurality of first socket parts 111 that connect 6 connection frames 200; a plurality of second socket parts 112 that connect 4 connection frames 200; and a plurality of third socket parts 113 that connect 3 connection frames 200.

[0078] A plurality of auxiliary socket frames 300 can be included and are arranged within the floating body unit group 10.

[0079] The floating body 11 may not be provided in the plurality of auxiliary socket frames 300.

[0080] The plurality of auxiliary socket frames 300 can include: a plurality of first auxiliary socket parts 310 that connect 4 connection frames 200; a plurality of second auxiliary socket parts 320 that connect 3 connection frames 200.

[0081] The plurality of first auxiliary socket parts 310 and the plurality of second auxiliary socket parts 320 can be formed into a hollow tubular shape with a hollow interior or the like for the insertion connection of the connection frame 200.

[0082] The plurality of first auxiliary socket parts 310 and the plurality of second auxiliary socket parts 320 can include a trapezoidal cross-section.

[0083] In addition, the upper part of the plurality of socket frames 100 can have a coupling hole 101 into which the structure 20 for supporting the photovoltaic panel module 30 can be inserted, or the structure 20 can be coupled to the socket frame 100 by bolt connection or welding connection without machining the coupling hole 101.

[0084] Channels or pedals 40 for maintenance and safety inspection or the like can be provided at the upper parts of the socket frame 100 and the connection frame 200.

[0085] In addition, the number (NN) of the floating bodies 11 of the floating body platform can be set to satisfy the following formula 1.

[0086] Number of floating bodies (NN) = 3XnX(n - 1)+1 --- Formula 1

[0087] Wherein, n represents the number of floating bodies arranged on Lc, and Lc can represent the length of one side of a regular hexagon inscribed in the set area forming a virtual circle.

[0088] In addition, the length Lp of the connecting frame 200 of the floating body platform can be set to satisfy the following formula 2.

[0089] Length of connecting frame Lp = Lc / (n - 1) ---- Formula 2

[0090] In addition, the number (NL) of the floating bodies 11 arranged within the lateral or longitudinal width of the floating body platform can be set to satisfy the following formula 3.

[0091] Number of floating bodies (NL) = 2X(n - 1) ---- Formula 3

[0092] In addition, the number (NP) of the floating body unit groups 10 of the floating body platform can be set to satisfy the following formula 4.

[0093] Number of floating body unit groups (NP) = 3 / 4 XnX(n - 2)+1 ---- Formula 4

[0094] The number (S) of triangles of the floating body platform can be set to satisfy the following formula 5.

[0095] Number of triangles of floating body platform (S) = 6X(n - 1)X(n - 1) ---- Formula 5

[0096] On the other hand, compared with fresh water, the area at sea is relatively wide, with less interference and higher degrees of freedom.

[0097] Therefore, in the present invention, as an example, the following method is described with reference to Figure 7 Assume that the area of the designated sea area where the floating power generation system is located is circular, and make the set area occupied by the floating body platform approximate the sea area.

[0098] Generally, the number (NB) and equivalent diameter (DE) of the floating bodies used to support the floating body platform depend on the force in the direction of gravity (the weights of the photovoltaic panel, the photovoltaic panel module support structure, the floating body platform, the floating bodies, etc.) and the force in the direction opposite to gravity (the buoyancy depending on the floating body shape and the floating body settlement rate).

[0099] The floating body unit group 10 of the present invention has floating bodies at 7 nodes. Therefore, the total number (NB) of floating bodies supporting the floating body platform is the same as Figure 7 the total number of nodes (NN) included in the floating body platform shown below, as shown in Formula 6 below.

[0100] NN = NB ---- Formula 6

[0101] Assuming that the number of nodes (number of floating bodies) included in one side of a regular hexagon inscribed in the area of the circular sea area is n, the total number of nodes (NN) included in the floating body platform can be set to satisfy Formula 7 below.

[0102] NN = 3 x n x (n - 1) + 1 --- Formula 7

[0103] Among them, n is always an even number.

[0104] In Figure 7 when the total number of floating bodies is specified as 37, n is 4.

[0105] At this time, assuming that the radius of the floating body platform is RC, the length Lp of the connecting frame 200 and the side length Lc of the floating body platform can be set to satisfy Formulas 8 and 9 as follows.

[0106] Lc = 2 x RC x sin 30 = RC --- Formula 8

[0107] Lp = Lc / (n - 1) --- Formula 9

[0108] In addition, since the floating body platform is a regular hexagon, the number of horizontal rows (NL) can be set to satisfy Formula 10 below.

[0109] NL = 2 x n - 1 --- Formula 10

[0110] As an embodiment, Figure 7 in it, NL is 7.

[0111] At this time, the total number (NP) of the actual floating body unit group 10 can be set to satisfy Formula 11 below.

[0112] NP = 3 / 4 x n x (n - 2) + 1 --- Formula 11

[0113] As an embodiment, Figure 7 in it, NP is 7.

[0114] The number (S) of triangles forming a truss in the floating body platform can be set to satisfy Formula 12 below.

[0115] S = 6 x (n - 1) x (n - 1) --- Formula 12

[0116] As an embodiment,Figure 7 S is 54 herein.

[0117] In addition, the set area can satisfy the following formula 13.

[0118] A0 = π x RC x RC --- Formula 13

[0119] The power generation area occupied by the floating body can be obtained by the following formula 14.

[0120] AB = 3 x Lc x Lc x cos 30 --- Formula 14

[0121] Therefore, the ratio of the power generation area to the set area can be obtained by the following formula 15.

[0122] AB / A0 = 82.7% --- Formula 15

[0123] In addition, Figure 8 This is the case where the floating body platform according to the present invention is circumscribed to a circular sea area with a radius (RC).

[0124] Different from the floating body platform inscribed in a circle, the length Lp of the connecting frame 200 and the side length Lc of the floating body platform can be set to satisfy the following formula 16.

[0125] Lc = 2 x RC x tan 30 --- Formula 16

[0126] Therefore, in this case, the ratio of the power generation area to the set area can be obtained by the following formula 17.

[0127] AB / A0 = 110.3% --- Formula 17

[0128] In addition, the photovoltaic power generation system according to an embodiment of the present invention may include the floating body platform as described above.

[0129] Hereinafter, reference will be made to Figures 1 to 12 to describe the operation of the floating body platform according to an embodiment of the present invention.

[0130] The floating body platform of the present invention includes: a plurality of socket frames 100 for setting the floating body 11; and a plurality of connecting frames 200 for connecting the plurality of socket frames 100, and the plurality of socket frames 100 and the plurality of connecting frames 200 are interconnected to form a plurality of floating body unit groups 10 of hexagonal truss structures.

[0131] Due to the large physical energy fluctuations of ocean currents generated by tidal phenomena such as typhoons including sea breezes, even if the entire floating offshore photovoltaic power generation system or a part thereof frequently moves back and forth / left and right / up and down (translation movement) or sways (rotation movement), the durability degradation can be minimized as much as possible, and the flow of ocean currents can be made smooth by forming a "Z" - shaped through - flow.

[0132] In addition, since the floating body unit group 10 has a hexagonal truss structure, the impact energy of the waves can be effectively dispersed to adjacent floating body unit groups 10.

[0133] In addition, by overlapping and arranging the floating body unit groups 10 through a plurality of socket frames 100 and a plurality of connecting frames 200, the entire system functions as a structure, thereby improving durability and impact resistance, and reducing the installation cost by improving the sea area setting efficiency.

[0134] In addition, for the floating body unit group 10 with a hexagonal truss structure, regardless of the sea current direction, the possibility of generating shock waves is very small, and the eddy current area where tidal stagnation occurs can be minimized.

[0135] In particular, the floating body unit group 10 with a hexagonal truss structure can be overlapped and combined (connected) into an integrated type through a plurality of socket frames 100 and a plurality of connecting frames 200 having an inverted trapezoidal cross-sectional shape. Therefore, a lifting force that squeezes the floating body platform in the direction of gravity is generated, increasing the sea breeze intensity, thereby achieving stabilization.

[0136] In addition, the plurality of socket frames 100 and the plurality of connecting frames 200 have an inverted trapezoidal cross-section, so that the lifting amount (the change amount in the vertical direction of the sea surface of the center line) of the connecting frame 200 when the sea breeze blows will decrease. By reducing the stress generated on the connecting frame 200 and the socket frame 100, a stable bonding force can be ensured.

[0137] In addition, a plurality of auxiliary socket frames 300 are provided inside the floating body unit group 10, so that the firmness of the floating body platform can be correspondingly increased.

[0138] Refer to Figure 5 (a), the floating body unit group 10 of the floating body platform is composed of floating bodies 11 with a set diameter connected to the vertices and the center point of a hexagon, and has 7 nodes (hereinafter referred to as "basic type 10b").

[0139] Refer to Figure 5 (b), when further structural stability is required, the floating body unit group 10 of the floating body platform is composed of two hexagonal truss structures and a center point, and has 13 nodes (hereinafter referred to as "reinforced type 10s").

[0140] In order to form an internal hexagonal truss structure, the connecting frame 200 of the auxiliary socket frame 300 is inserted and connected to the socket frame 100 located at the center point. At this time, if additional buoyancy of the floating body unit group 10 is required, floating bodies 11 can be provided at each node of the internal small hexagon.

[0141] Figure 6 Show Figure 5 the basic type 10b of the floating body platform in (a) andFigure 5 Hybrid structure in which the enhanced 10s of the floating body platform in (b) are mixed together.

[0142] For such a hybrid type of floating body platform, if the external forces such as ocean currents, waves, and sea breezes in the set water area are relatively large, the enhanced 10s are placed at the position where the external force has the greatest influence, and around it, floating body platforms 10s' with a reduced number of nodes of the enhanced 10s are arranged, and then the floating body platforms of the basic type 10b are arranged.

[0143] At this time, in order to strengthen the connection force between the floating bodies 11 to maintain the structural stability, a connecting frame 200' can be added between two adjacent socket frames 100 among the floating body unit groups 10 to form a new floating body unit group 10 (represented by a dotted line).

[0144] Thus, it can be seen that for the structural reinforcement of the floating body unit group 10 and the floating platform according to the present invention, it can be achieved only through the simple connection between the socket frame 100 and the connecting frames 200, 200'.

[0145] In addition, for the floating body platform of the present invention, in order to effectively disperse the six-degree-of-freedom forced motion in a double-symmetrical structure, by using a plurality of socket frames 100, a plurality of connecting frames 200, etc., the floating body unit groups 10 are arranged in a regular hexagon without additional connection means between the floating body unit groups.

[0146] Thus, through the buffering effect between the geometrically overlapping floating body unit groups 10, the propulsion and sway of the floating photovoltaic power generation system can be reduced, thereby reducing the change in the tilt angle of the photovoltaic panel module caused by waves or ocean currents.

[0147] Figures 9 to 11 This is a preferred embodiment of the present invention. Regardless of the shape of the floating body platform, when the area occupied by one floating body platform is the same, the set area and the power generation area are compared by illustration according to the comparative example and the embodiment of the present invention.

[0148] For the comparative example, the positions of the floating bodies are different, rather than being located at the nodes of the floating body platform as in the present invention. However, for the sake of comparison, it is assumed that the floating bodies are located at the nodes of the floating body platform as in the present invention, and it is assumed that more than 50% of the floating body platform area in the sea area is effective, so as to approximate the sea area as much as possible.

[0149] As Figure 9 shown, in the case of the quadrilateral floating body platform of the comparative example, it can be seen that there is asymmetry in the direction of the set area. The total number of floating body unit floats constituting the floating body platform is 12, and the total number of floating bodies is 20.

[0150] In addition, as Figure 10 shown, in the case of the random arrangement of the hexagonal floating body unit floats in the comparative example, compared with Figure 9Similarly, there is an asymmetry in the direction of the set area. The total number of pontoons of the floating body units is 10, and the total number of floating bodies is 32.

[0151] However, as Figure 11 shown, in the case of the floating body platform of the embodiment of the present invention, regardless of the direction of the set area, symmetry is maintained. The total number of unit pontoons is 7, and the number of floating bodies is 37.

[0152] Therefore, for the embodiment of the present invention, it is possible to reduce the number of unit pontoons while increasing the number of floating bodies that provide buoyancy.

[0153] In addition, the repeated nodes between the floating body unit pontoons are shared by the floating body unit pontoons with each other.

[0154] In particular, as can be seen from Figure 11 for the floating body unit pontoon 4 located at the center of the floating body platform, one floating body is located on the central node, and it can be simply made with one floating body socket 100 and a connecting frame 200.

[0155] In addition, since the floating body unit pontoons arranged along the sides of the hexagon are simply connected by the connecting frame 200 to naturally generate geometric unit pontoons (as an example, the shaded area between pontoon 2 and pontoon 5), the durability of the floating body platform is further increased.

[0156] That is, for the first row horizontally above, the actual number of floating body unit pontoons arranged along one side is 2, but geometrically it is like 3 floating body unit pontoons overlapping.

[0157] Figure 12 According to an embodiment of the present invention, when a floating body platform composed of a plurality of honeycomb-shaped floating body unit pontoons is in a regular hexagonal arrangement, it shows the actual unit pontoons that need to be set according to the number of floating bodies, the geometric unit pontoons generated by simply connecting adjacent floating body unit pontoons with a connecting frame, and the total number of floating body unit pontoons overlapping inside the floating body platform.

[0158] As the number of floating bodies increases, that is, as the set area increases, the number of geometric unit pontoons increases rapidly, which is more economical and affordable. At the same time, it strengthens the binding force between the unit pontoons to prevent separation, thereby improving the durability and impact resistance against waves and swells.

[0159] In addition, when using the circumscribed hexagonal floating body platform of the present invention, the set area (utilization area) can perfectly occupy the sea area, as Figure 8 shown.

[0160] Although the present disclosure has been described through the above-described preferred embodiments, the present invention is not limited to the above embodiments. Without departing from the scope of the claims, those skilled in the technical field to which the present invention pertains can make various modifications and variations.
