[0017] Optionally, the floating offshore photovoltaic platform also includes a mooring cable, one end of which is connected to the outer frame and the other end of which is fixed.

[0018] Another objective of this invention is to provide a floating offshore photovoltaic system platform that enables the photovoltaic power generation system to float stably while ensuring the safe operation and economic feasibility of the photovoltaic power generation system.

[0019] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0020] A floating offshore photovoltaic (PV) combination platform is provided, comprising multiple floating offshore PV platforms as described above, wherein the multiple floating offshore PV platforms are arranged at intervals, and the floating offshore PV combination platform has N2 rows × M2 columns of the floating offshore PV platforms.

[0022] The floating offshore photovoltaic combined platform also includes anti-collision barrels and bifurcated mooring cables. A set of anti-collision barrels is set between any two adjacent floating offshore photovoltaic platforms. One end of the bifurcated mooring cable is divided into two connecting ropes, which are respectively connected to two adjacent outer frames. The other end of the bifurcated mooring cable is fixed.

[0023] Optionally, the floating offshore photovoltaic combined platform has N2 rows × M2 columns of the floating offshore photovoltaic platform, where N2 ≥ and M2 ≥ 2;

[0025] Optionally, the floating offshore photovoltaic combined platform further includes a mooring cable, one end of which is connected to the corner of the outermost ring of the floating offshore photovoltaic combined platform's outer frame, and the other end of which is fixed.

[0026] The beneficial effects of this utility model are as follows:

[0027] This invention discloses a floating offshore photovoltaic platform, comprising an outer frame, photovoltaic cores, rigid connectors, and elastic connectors. The outer frame has an internal space. Multiple photovoltaic cores are included, each with a first connecting ring on its outer periphery. The photovoltaic cores are arranged at intervals to form a photovoltaic core group with N1 rows × M1 columns of photovoltaic cores. This photovoltaic core group can float on the sea and reside within the internal space. Multiple rigid connectors are included, with each connector's two ends connected to the first connecting rings of two adjacent photovoltaic cores, allowing the rigid connector to rotate relative to the first connecting rings. Multiple elastic connectors are included, with one end connected to the outer frame and the other end connected to the first connecting ring of the outermost ring of photovoltaic cores in the photovoltaic core group.

[0028] A photovoltaic (PV) core assembly is composed of multiple PV cores connected by rigid connectors. These rigid connectors maintain a fixed distance between adjacent PV cores, preventing them from approaching each other and colliding. However, the rigid connectors can rotate relative to the first connecting ring, allowing adjacent PV cores to rotate relative to each other. When the PV cores move on the sea surface, this can release some of the wave force. The PV core assembly is located within an outer frame. The outer frame effectively maintains the matrix shape of the PV core assembly, preventing large displacements and collisions between the PV cores, protecting electrical equipment and cables, and preventing potential floating debris from colliding with the internal structure of the outer frame, thus ensuring the safe and stable operation of the floating offshore PV platform. Additionally, the PV core assembly is connected to the outer frame via elastic connectors. These elastic connectors allow the distance between the PV core assembly and the outer frame to change. However, the selection of these elastic connectors should avoid direct contact between the PV core assembly and the outer frame, ensuring a constant distance between them. In addition to releasing some of the wave force on the photovoltaic core assembly through elastic displacement, the wave load on the entire floating offshore photovoltaic platform can also be reduced, thereby reducing the ultimate load on the outer frame and mooring force, ultimately reducing various costs.

[0029] This invention proposes a floating offshore photovoltaic (PV) system platform, comprising multiple floating PV platforms. These platforms are arranged at intervals, with the platform having N² rows × M² columns. Specifically, the floating PV system platform provided by this invention can have two arrangement configurations: one where the floating PV platforms have only one row or one column, meaning a maximum of two floating PV platforms are adjacent; and another where the floating PV platforms have multiple rows and columns, meaning each floating PV platform is adjacent to at least three other floating PV platforms. This floating PV system platform enables the PV power generation system to float stably, while ensuring the safe operation and economic feasibility of the PV power generation system.

[0047] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] This embodiment provides a floating offshore photovoltaic platform 100, including an outer frame 1, photovoltaic cores 2, rigid connectors 3, and elastic connectors 4. The outer frame 1 has an internal space. Multiple photovoltaic cores 2 are provided, each with a first connecting ring 221 on its outer periphery. The multiple photovoltaic cores 2 are arranged at intervals to form a photovoltaic core group with N1 rows × M1 columns of photovoltaic cores 2. The photovoltaic core group can float on the sea and is located within the internal space. Multiple rigid connectors 3 are provided, with both ends of each rigid connector 3 connected to the first connecting rings 221 of two adjacent photovoltaic cores 2, and the rigid connector 3 can rotate relative to the first connecting rings 221. Multiple elastic connectors 4 are provided, with one end connected to the outer frame 1 and the other end connected to the first connecting rings 221 of the outermost ring of photovoltaic cores 2 in the photovoltaic core group.

[0050] The photovoltaic core assembly is composed of multiple photovoltaic cores 2 connected by rigid connectors 3. The rigid connectors 3 ensure that adjacent photovoltaic cores 2 maintain a fixed distance from each other, preventing them from colliding. However, the rigid connectors 3 can rotate relative to the first connecting ring 221, allowing adjacent photovoltaic cores 2 to rotate relative to each other. When the photovoltaic cores 2 move on the sea surface, this releases some of the wave force. The photovoltaic core assembly is located inside the outer frame 1. The outer frame 1 effectively maintains the matrix shape of the photovoltaic core assembly, preventing large displacements and collisions between the photovoltaic cores 2, protecting electrical equipment and cables, and preventing potential floating objects from colliding with the internal structure of the outer frame 1, thus protecting the safe and stable operation of the floating offshore photovoltaic platform 100. Furthermore, the photovoltaic core assembly is connected to the outer frame 1 via elastic connectors 4. The elastic connectors 4 have elasticity, allowing the distance between the photovoltaic core assembly and the outer frame 1 to change. However, the elasticity of the elastic connectors 4 should be selected to prevent the photovoltaic core assembly from contacting the outer frame 1, ensuring that there is always a distance between the photovoltaic cores 2 and the outer frame 1. In addition to releasing part of the wave force of the photovoltaic core assembly through elastic displacement, the wave load on the entire floating offshore photovoltaic platform 100 can also be reduced, thereby reducing the ultimate load on the outer frame 1 and reducing mooring force, ultimately reducing various costs.

[0051] Optionally, such as Figures 1 to 3 As shown, the floating offshore photovoltaic platform 100 also includes a mooring cable 5. One end of the mooring cable 5 is connected to the outer frame 1, and the other end is fixed. The mooring cable 5 is a commonly used cable in offshore engineering. One end of the mooring cable 5 is connected to the outer frame 1, and the other end is connected to a mooring foundation. The mooring foundation can be a fixed platform, or a pile anchor, gravity anchor block, etc., to fix the other end of the mooring cable 5, thereby ensuring that the floating offshore photovoltaic platform 100 can only float in the designated area. Mooring bollards 111 are installed at the outer corner of the outer frame 1, and one end of the mooring cable 5 is connected to the mooring bollard 111 of the outer frame 1.

[0052] In this embodiment, the outer frame 1 is welded from hollow steel pipes. The surface of the outer frame 1 is coated with protective paint, and cathodic protection and other measures are adopted to reduce the corrosive effect of seawater on the outer frame 1. In addition, the outer frame 1 itself is welded to achieve a watertight effect and has buoyancy, ensuring that at least its upper surface is above the sea surface. The outer frame 1 has a rectangular structure, and the internal space of the outer frame 1 is also rectangular.

[0053] Optionally, mooring bollards 111 are installed at the four corners of the outer frame 1 to connect the mooring lines 5. To ensure the structural strength of the connection between the outer frame 1 and the mooring lines 5, local reinforcement structures can be added at the locations where the mooring bollards 111 are installed on the outer frame 1.

[0054] In this embodiment, the photovoltaic core 2 includes a photovoltaic panel 21 and a floating core 22. The photovoltaic panel 21 is disposed on the upper surface of the floating core 22, and the floating core 22 can carry the photovoltaic panel 21 to float on the sea surface. The floating core 22 is made of lightweight materials, such as modified HDPE (high-density polyethylene), aluminum-like polymer composite materials, etc. The selection of its materials is prior art and will not be described in detail here.

[0055] Furthermore, such as Figure 4 As shown, the outer periphery of the photovoltaic core 2 includes multiple connecting surfaces 222 connected in sequence, and each connecting surface 222 is provided with a set of first connecting rings 221. The photovoltaic core 2 located at the outermost layer of the photovoltaic core group is connected to the outer frame 1 through a portion of the first connecting rings 221, while the other portion of the first connecting rings 221 not connected to the outer frame 1 is connected to the adjacent photovoltaic core 2. The photovoltaic core 2 not located at the outermost layer of the photovoltaic core group is connected to the adjacent photovoltaic core 2 through all of the first connecting rings 221. In this embodiment, the photovoltaic core 2 has a cuboid structure, and the outer periphery of the cuboid structure includes four connecting surfaces 222 connected in sequence, so each photovoltaic core 2 has four sets of first connecting rings 221. The outermost photovoltaic core 2 of the photovoltaic core assembly is connected to the outer frame 1 via two sets of first connecting rings 221. These two sets of first connecting rings 221 are respectively disposed on two vertical connecting surfaces 222, and these two connecting surfaces 222 are closer to the outer frame 1 than the remaining two connecting surfaces 222. The two sets of first connecting rings 221 disposed on the remaining two connecting surfaces 222 are respectively connected to two adjacent photovoltaic cores 2. The photovoltaic cores 2 that are not located on the outermost layer of the photovoltaic core assembly are connected to four adjacent photovoltaic cores 2 via four sets of first connecting rings 221.

[0056] In this embodiment, when the rectangular photovoltaic cores 2 are arranged into a photovoltaic core group with N1 rows × M1 columns, the spacing between two adjacent photovoltaic cores 2 is consistent. The photovoltaic cores 2 can also be other structures such as regular hexagons, which are not limited here.

[0057] In this embodiment, each group of first connecting rings 221 includes two first connecting rings 221 spaced apart, and one first connecting ring 221 is connected to a rigid connector 3 to ensure stable connection between two adjacent photovoltaic cores 2.

[0058] Optionally, such as Figure 4As shown, the rigid connector 3 includes a connecting rod 31 and two second connecting rings 32. The two second connecting rings 32 are respectively disposed at both ends of the connecting rod 31, and the second connecting rings 32 can rotate relative to the first connecting ring 221. In this embodiment, the connecting rod 31 is a steel rod, and the second connecting rings 32 and the first connecting ring 221 can also be made of steel. The second connecting ring 32 can be formed by fitting the base component for preparing the second connecting ring 32 onto the first connecting ring 221 and then welding the base component.

[0059] Optionally, such as Figure 5 As shown, the elastic connector 4 includes an elastic rope 41 and two third connecting rings 42. The two third connecting rings 42 are respectively disposed at both ends of the elastic rope 41, and the third connecting rings 42 can rotate relative to the first connecting ring 221 and the outer frame 1. In this embodiment, the elastic rope 41 is made of a highly elastic material, such as rubber, and the third connecting rings 42 can be made of the same material as the elastic rope 41. The third connecting rings 42 are rope loops that can pass through the first connecting ring 221 and the outer frame 1 to ensure that the connection of the three has room for movement.

[0060] Optionally, refer to Figure 2 and Figure 5 The outer frame 1 includes a frame body 11 and a hoop connector 12. The hoop connector 12 is detachably mounted on the frame body 11 and is connected to the elastic connector 4. In this embodiment, the hoop connector 12 includes two half-rings, which are connected by bolts to form a complete ring. When fixing the hoop connector 12 to the outer frame 1, the bolts can be released first to open the hoop connector 12, allowing the two half-rings to surround a truss of the outer frame 1. Then, the two half-rings are fixed to the truss using bolts. The hoop connector 12 also includes a mounting through hole. In specific implementation, the third connecting ring 42 of the elastic connector 4 can be movably positioned within the mounting through hole before the hoop connector 12 is fixed to the outer frame 1.

[0061] Example 2

[0062] like Figures 6 to 8As shown, this embodiment also provides a floating offshore photovoltaic (PV) system platform 200, comprising multiple floating offshore PV platforms 100. The multiple floating offshore PV platforms 100 are arranged at intervals, and the floating offshore PV system platform 200 has N² rows × M² columns of floating offshore PV platforms 100. That is, the floating offshore PV system platform 200 provided in this embodiment can have two arrangement forms: one is that the floating offshore PV system platform 200 has only one row or one column, that is, at most two floating offshore PV platforms 100 are adjacent; the other is that the floating offshore PV system platform 200 has multiple rows and multiple columns, that is, each floating offshore PV platform 100 is adjacent to at least three floating offshore PV platforms 100. This floating offshore PV system platform 200 enables the PV power generation system to float stably, while ensuring the safe operation and economic feasibility of the PV power generation system.

[0063] Optionally, such as Figure 10 As shown, the floating offshore photovoltaic (PV) platform 200 has N2 rows × M2 columns of floating offshore PV platforms 100, where N2=1 and M2≥2, or M2=1 and N2≥2. In this embodiment, N2=1 and M2=2, meaning the floating offshore PV platform 200 includes two floating offshore PV platforms 100. In other embodiments, a matrix form of floating offshore PV platform 200 with N2=1 and M2>2 can also be set as needed. Since at least one of N2 or M2 is limited to 1, the floating offshore PV platform 200 in the form of N2=1 and M2≥2, or M2=1 and N2≥2, is essentially a series of floating offshore PV platforms 100 arranged in a line.

[0064] The floating offshore photovoltaic combined platform 200 also includes anti-collision barrels 6, forked mooring cables 7, and mooring cables 5. A set of anti-collision barrels 6 is installed between any two adjacent floating offshore photovoltaic platforms 100. One end of the forked mooring cable 7 splits into two connecting ropes, which are respectively connected to two adjacent outer frames 1. The other end of the forked mooring cable 7 is fixed. In this embodiment, using the forked mooring cable 7 to connect two adjacent outer frames 1 ensures that the two adjacent floating offshore photovoltaic platforms 100 do not separate. Mooring cables 5 are still installed at the corners of the floating offshore photovoltaic combined platform 200 to allow the floating offshore photovoltaic combined platform 200 to float in the designated area.

[0065] In this embodiment, the anti-collision barrel 6 is made of a highly elastic material, such as rubber. The anti-collision barrel 6 is positioned between two adjacent floating offshore photovoltaic platforms 100 to prevent them from colliding with each other when the sea surface is fluctuating. Suspension rings 112 are provided on the outer frame 1, and suspension ropes can be used to connect the anti-collision barrel 6 to the suspension rings 112. Two suspension rings 112 are provided on each frame, and four suspension rope mounting areas are evenly spaced around the circumference of each anti-collision barrel 6. This allows each anti-collision barrel 6 to be connected to two outer frames 1 via four suspension ropes, preventing the anti-collision barrel 6 from rotating and ensuring that it remains positioned between the two adjacent outer frames 1.

[0066] In practice, the suspension ring 112 is also located near the corner of the outer frame 1, but its location differs from that of the mooring bollard 111. The suspension ring 112 is located on one side parallel to the two adjacent outer frames 1, so that the anti-collision barrel 6 can be positioned between the two floating offshore photovoltaic platforms 100. The mooring bollard 111 is located at the corner of the outer frame 1, so that when the two floating offshore photovoltaic platforms 100 are fixed by the forked mooring cable 7, the force exerted by the forked mooring cable 7 on both is along the diagonal of the outer frame 1.

[0067] Optionally, such as Figure 9 As shown, the floating offshore photovoltaic (PV) combination platform 200 has N2 rows × M2 columns of floating offshore PV platforms 100, where N2 ≥ and M2 ≥ 2. In this embodiment, N2 = 2 and M2 = 2, meaning the floating offshore PV combination platform 200 includes 4 floating offshore PV platforms 100. In other embodiments, a matrix form of floating offshore PV combination platform 200 with N2 > 2 and M2 > 2 can also be configured as needed.

[0068] The floating offshore photovoltaic (PV) platform 200 also includes anti-collision barrels 6, mooring cable loops 8, and forked mooring cables 7. A set of anti-collision barrels 6 is installed between any two adjacent floating PV platforms 100. One end of the forked mooring cable 7 splits into two connecting ropes, and the other end of the forked mooring cable 7 is fixed. The two connecting ropes are respectively connected to two adjacent outer frames 1. The mooring cable loops 8 are used to connect the corners where four adjacent outer frames 1 are close to each other. In this embodiment, because the floating PV platform 200 has multiple rows and columns, each floating PV platform 100 has at least three adjacent floating PV platforms 100. Therefore, in addition to using the forked mooring cables 7 to connect two adjacent outer frames 1 to ensure that two adjacent floating PV platforms 100 do not separate, the mooring cable loops 8 are used to connect the corners where four adjacent outer frames 1 are close to each other to ensure that multiple floating PV platforms 100 located in the central area of ​​the floating PV platform 200 can also be connected to each other. In this embodiment, the mooring cable loop 8 is connected to the mooring bollard 111 of the outer frame 1.

[0069] Optionally, the floating offshore photovoltaic platform 200 also includes a mooring cable 5, one end of which is connected to the outer frame 1, and the other end of which is fixed. The mooring cable 5 is a commonly used cable in offshore engineering. One end of the mooring cable 5 is connected to the outer frame 1, and the other end is connected to a mooring foundation. The mooring foundation can be a fixed platform, a pile anchor, a gravity anchor block, etc., to fix the other end of the mooring cable 5, thereby ensuring that the floating offshore photovoltaic platform 100 can only float in the designated area. In this embodiment, one end of the mooring cable 5 is connected to the mooring bollard 111 of the outer frame 1.

[0070] This embodiment provides a floating offshore photovoltaic combination platform 200. In specific use, the combination scheme can be customized according to the project situation, and the combination method is simple and efficient. Specifically, after connecting the connected floating offshore photovoltaic platforms 100, and adding the anti-collision barrels 6, a structural form can be formed that can both transmit tension through mutual connection and avoid mutual collision.

[0071] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
