Description

Technical Field

[0001] The present invention relates to the field of offshore photovoltaic technology, and in particular to a platform structure and an installation method of an offshore floating photovoltaic module. Background Art

[0002] As an indispensable part of new energy power generation facilities, offshore photovoltaic panel support platforms have extremely special and complex working environments. These platforms are exposed to the ocean environment for a long time, and not only have to face the test of harsh climatic conditions such as high temperature, high humidity, and high salt spray, but also have to withstand the impact of natural forces such as waves and tides. However, the current design of offshore photovoltaic panel support platforms faces two core challenges: the inability to achieve lightweight and the lack of modular design.

[0003] Lightweighting is one of the important goals in the design of offshore photovoltaic panel support platforms, but this goal is difficult to achieve due to limitations in material selection and structural design. The platform needs to use high-strength, corrosion-resistant materials to ensure its stability and durability, but these materials are often dense, resulting in a heavy overall weight of the platform. This not only increases material costs, but also increases the difficulty of construction and installation, while also affecting the efficiency of transportation and deployment of the platform.

[0004] Modular design is an important concept in the field of modern engineering, which helps to improve production efficiency, reduce costs and simplify the construction process. However, the current design of offshore photovoltaic panel support platforms often lacks modularity, which makes it difficult to achieve standardization and serialization during the manufacturing, transportation and installation of the platform. This not only increases the difficulty of construction, but also prolongs the construction period and increases the overall cost. At the same time, the lack of modularity also limits the flexibility and scalability of the platform, making it difficult to adapt to offshore photovoltaic power generation projects of different scales and needs.

[0005] In summary, the offshore photovoltaic panel support platform faces two major challenges in the design and manufacturing process: the difficulty in achieving lightweight and the lack of modularity. These problems not only affect the performance and cost-effectiveness of the platform, but also limit its application and development in the field of renewable energy power generation. Therefore, the development of an offshore photovoltaic panel support platform that can achieve both lightweight and modular design has become an important issue that needs to be solved in the current field of renewable energy power generation technology. Summary of the invention

[0006] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide a platform structure and installation method of an offshore floating photovoltaic module to solve the technical problem that the photovoltaic modules in the prior art cannot be lightweight and modularized.

[0007] The present invention is achieved through the following technical solutions: In a first aspect, the present invention provides a platform structure of an offshore floating photovoltaic module, comprising a plurality of photovoltaic module modules; wherein floating tubes are connected between adjacent photovoltaic module modules for floating on the sea surface through the floating tubes; the photovoltaic module modules comprise photovoltaic modules and a supporting frame; the photovoltaic modules are arranged on the top of the supporting frame, and the side walls of the floating tubes are connected and arranged on the bottom side of the supporting frame.

[0008] Preferably, the support frame includes a frame structure and a top plate; the top plate is arranged on the top of the frame structure, and the photovoltaic component is arranged on the top plate, wherein the top plate corresponds to the panel size of the photovoltaic component; the side wall of the floating tube is connected and arranged at the bottom of the frame structure.

[0009] Furthermore, the frame structure includes a plurality of supporting legs, which are arranged around the edge of the top plate, one end of which is respectively arranged at the corner of the top plate; the other end is connected to the side wall of the corresponding side floating tube, wherein adjacent supporting legs are connected by a connecting bracket.

[0010] Furthermore, the lengths of the plurality of supporting legs are equal, and the plurality of supporting legs are arranged obliquely between the top plate and the floating cylinder.

[0011] Preferably, the float comprises a limiting unit, a first buoyancy block, a connecting piece and a second buoyancy block; the first buoyancy block, the connecting piece and the second buoyancy block are sequentially sleeved on the limiting unit, and one side of the bottom of the support frame is connected to the connecting piece.

[0012] Furthermore, the limiting unit includes two sets of limiting plates and limiting support rods; The two groups of limit plates are respectively arranged in parallel at the two ends of the limit strut, and the first buoyancy block, the connecting piece and the second buoyancy block are sequentially sleeved on the limit strut and located between the two groups of limit plates.

[0013] Furthermore, the two groups of limiting plates, the first buoyancy block, the connecting piece and the second buoyancy block have the same outer diameter.

[0014] Furthermore, the first buoyancy block and the second buoyancy block have the same structure, both of which are sleeve structures, and the surface of which is a continuously undulating plane structure.

[0015] Furthermore, a buffer plate is provided on the connecting piece, the surface of the buffer plate is higher than the surface of the connecting piece, and the ends of the first buoyancy block and the second buoyancy block are both in contact with the buffer plate.

[0016] In a second aspect, the present invention further provides a method for installing a platform structure of an offshore floating photovoltaic module, based on the above-mentioned platform structure of an offshore floating photovoltaic module, comprising the following steps: Several photovoltaic modules are installed on several supporting frames respectively to form several photovoltaic module modules; several photovoltaic module modules are laid flat, and the bottom sides of adjacent photovoltaic module modules are connected by several floating tubes respectively to form an offshore floating photovoltaic module platform.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a platform structure for an offshore floating photovoltaic module. By deploying the photovoltaic module modules on the sea surface in the form of floating tube connections, the difficulty of installation is effectively reduced. The floating tube connection facilitates assembly, disassembly and rearrangement at sea, thereby improving the flexibility and maintainability of the system. The lightweight design of the floating tube can reduce the load on the platform, reduce material costs and construction difficulties, and improve energy conversion efficiency and photovoltaic power generation. The present invention focuses on lightweight and platform modularization, which can not only improve the economy and reliability of the floating photovoltaic system, but also has important significance for promoting the development of sustainable energy.

[0018] Furthermore, the support frame includes a frame structure and a top plate; the top plate is arranged on the top of the frame structure, and the photovoltaic module is arranged on the top plate, wherein the top plate corresponds to the panel size of the photovoltaic module; the side wall connection of the floating drum is arranged at the bottom of the frame structure. The frame structure, as the main bearing body supporting the photovoltaic module, can ensure the stability of the photovoltaic module when floating on the sea. The combination of the top plate and the frame structure further enhances the bearing capacity of the overall structure, so that the photovoltaic module can be safely and stably installed on the top plate. The side wall connection of the floating drum is arranged at the bottom of the frame structure, which can effectively disperse the buoyancy and make the entire platform structure more stable.

[0019] Furthermore, the frame structure includes a plurality of supporting legs, and the plurality of supporting legs are arranged around the edge of the top plate, one end of which is respectively arranged at the corner of the top plate; the other end is connected to the side wall of the corresponding side floating tube, wherein adjacent supporting legs are connected by a connecting bracket. The supporting legs are arranged around the edge of the top plate to form a stable supporting structure, which ensures the stability of the top plate and the photovoltaic components thereon when floating on the sea. The other end of the supporting leg is connected to the side wall of the corresponding side floating tube. This connection method effectively transfers the buoyancy to the entire platform structure, thereby enhancing the rigidity of the overall structure. Adjacent supporting legs are connected by connecting brackets, which enhances the stability and crosswind resistance of the frame structure, so that the platform structure can better withstand the impact of severe weather at sea.

[0020] Furthermore, the lengths of the plurality of support legs are equal, and the plurality of support legs are arranged at an angle between the top plate and the floating tube. The lengths of all support legs are equal, which enables the top plate to remain horizontal, thereby ensuring that the photovoltaic modules can be evenly stressed, avoiding damage or performance degradation caused by uneven stress. The inclined arrangement of the support legs can offset the impact of waves to a certain extent, improve the anti-overturning ability of the platform structure, and ensure the stability of the entire platform when floating on the sea.

[0021] Furthermore, the float includes a limit unit, a first buoyancy block, a connecting piece and a second buoyancy block; the first buoyancy block, the connecting piece and the second buoyancy block are sequentially sleeved on the limit unit, and one side of the bottom of the support frame is connected to the connecting piece. By adjusting the volume or material of the first buoyancy block and the second buoyancy block, the total buoyancy of the float can be easily adjusted to adapt to the water depth and wave conditions in different sea areas, thereby ensuring the stability and safety of the platform structure. The connecting piece not only serves as a connector between the first buoyancy block and the second buoyancy block, but also plays a role in connecting the float to the support frame. This makes the connection between the float and the support frame more firm and reliable, thereby improving the integrity and stability of the entire platform structure.

[0022] Furthermore, the limiting unit includes two sets of limiting plates and limiting struts; the two sets of limiting plates are respectively arranged in parallel at both ends of the limiting struts, and the first buoyancy block, the connecting plate and the second buoyancy block are sequentially mounted on the limiting struts and are located between the two sets of limiting plates. The limiting unit provides stable support and positioning for the buoyancy block through two sets of parallel limiting plates. It ensures that the buoyancy block can be accurately mounted on the limiting struts and maintained in the correct position, thereby improving the structural stability of the entire floating tube. The presence of the limiting plates also prevents the buoyancy block from shifting or falling off due to wave impact when floating on the sea, further enhancing the safety and reliability of the platform structure.

[0023] Furthermore, the two groups of limit plates, the first buoyancy block, the connecting piece and the second buoyancy block have the same outer diameter. The design of the same outer diameter allows these components to adopt standardized manufacturing processes and materials, thereby reducing production costs and manufacturing difficulties.

[0024] Furthermore, the first buoyancy block and the second buoyancy block have the same structure, both of which are sleeve structures, and the surface is a continuously undulating plane structure. The continuously undulating plane structure increases the contact area between the buoyancy block and the surrounding water body, helps to distribute the buoyancy more evenly, reduces the tilt and shaking of the platform structure, and at the same time improves the surface roughness, which can dissipate wave energy to a certain extent.

[0025] Furthermore, a buffer plate is provided on the connecting piece, the surface of the buffer plate is higher than the surface of the connecting piece, and the ends of the first buoyancy block and the second buoyancy block are both in contact with the buffer plate. The buffer plate provides an additional support surface for the first buoyancy block and the second buoyancy block. When the floating drum encounters wave impact at sea, the end of the buoyancy block will first contact the buffer plate, thereby reducing the damage to the buoyancy block caused by direct impact. This helps to extend the service life of the buoyancy block and reduce the maintenance and replacement costs caused by impact.

[0026] The present invention also provides a method for installing a platform structure of an offshore floating photovoltaic module, by installing the photovoltaic module on a support frame to form a photovoltaic module module, so that the installation process is more modular. This modular design simplifies the installation steps, reduces the difficulty of installation, and improves work efficiency. At the same time, it makes the layout and connection of photovoltaic modules more flexible and can be adjusted according to actual needs. Adjacent photovoltaic module modules are connected by floating drums to form a stable offshore floating platform structure. The floating drum not only provides buoyancy, but also enhances the stability and wind and wave resistance of the platform structure. The platform can operate stably in harsh marine environments and ensure the power generation efficiency of photovoltaic modules. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a platform structure and installation method for an offshore floating photovoltaic module, so as to solve the technical problem that the photovoltaic modules in the prior art cannot be lightweight and modularized.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: Example 1 See also Figure 1 , Figure 2 as well as Figure 3 In one embodiment of the present invention, a platform structure of an offshore floating photovoltaic assembly is provided, comprising a plurality of photovoltaic assembly modules 1; wherein a floating cylinder 4 is connected between adjacent photovoltaic assembly modules 1, and is used to float on the sea surface through the floating cylinder 4; the photovoltaic assembly module 1 comprises a photovoltaic assembly 2 and a supporting frame 3; the photovoltaic assembly 2 is arranged on the top of the supporting frame 3, and the side wall of the floating cylinder 4 is connected and arranged on one side of the bottom of the supporting frame 3, such as Figure 4 shown.

[0031] Specifically, according to Figure 3 and Figure 4 As shown, the support frame 3 includes a frame structure and a top plate 33; the top plate 33 is arranged on the top of the frame structure, and the photovoltaic component 2 is arranged on the top plate 33, wherein the top plate 33 corresponds to the panel size of the photovoltaic component 2; the side wall of the floating tube 4 is connected and arranged at the bottom of the frame structure.

[0032] In this embodiment, the frame structure constitutes the supporting foundation of the floating photovoltaic system, and has sufficient strength and stability to support the weight of the upper structure and the photovoltaic module 2, while resisting external forces such as water surface fluctuations and wind. The top plate 33 is arranged on the top of the frame structure, corresponding to the size of the panel of the photovoltaic module 2, and is used to fix and support the photovoltaic module 2. The top plate 33 may be made of a flat and corrosion-resistant material to ensure that the photovoltaic module 2 can stably and efficiently receive solar energy.

[0033] The frame structure includes a plurality of supporting legs 31, which are arranged around the edge of the top plate 33, one end of which is arranged at the corner of the top plate 33; the other end is connected to the side wall of the corresponding side floating tube 4, wherein adjacent supporting legs 31 are connected by a connecting bracket 32.

[0034] In this embodiment, the support legs 31 serve as the main supporting members of the frame structure and are arranged around the edge of the top plate 33. One end of these support legs 31 is fixed at the corner of the top plate 33, and the other end is connected to the side wall of the floating tube 4 on the corresponding side. The design of the support legs 31 ensures that the top plate 33 and the photovoltaic components 2 thereon can be stably suspended on the water surface and withstand loads under various environmental conditions. The connecting brackets 32 play a role in connecting and reinforcing adjacent support legs 31. The frame structure of the connecting brackets 32 forms a more stable whole, which enhances the stability of the system and its ability to resist wind pressure and wave impact.

[0035] The lengths of the plurality of support legs 31 are all equal, and the plurality of support legs 31 are arranged obliquely between the top plate 33 and the floating tube 4 .

[0036] In this embodiment, the support legs 31 are all of equal length and are arranged at an angle, so that they can form a stable triangular or polygonal support structure between the top plate 33 and the float 4. This structure helps to evenly distribute the load and prevent structural damage caused by excessive force on a single point. The inclined support legs 31 can more effectively resist external forces such as wave impact and wind from the water surface. They jointly bear these forces by forming a stable support network, thereby ensuring the stability of the entire floating photovoltaic system. The inclined support legs 31 not only provide the necessary support, but also adjust the buoyancy of the system together with the float 4 through the design of their inclination angle and length. This design enables the system to maintain a stable floating state under different water level conditions, ensuring that the photovoltaic components 2 can always receive sufficient sunlight.

[0037] Specifically, according to Figure 5 As shown, the float 4 includes a limiting unit, a first buoyancy block 42, a connecting piece 43 and a second buoyancy block 44; the first buoyancy block 42, the connecting piece 43 and the second buoyancy block 44 are sequentially sleeved on the limiting unit, and one side of the bottom of the support frame 3 is connected to the connecting piece 43.

[0038] In this embodiment, the limiting unit is the core structural part of the floating drum 4, which plays the role of positioning and fixing other components. The limiting unit may be made of rigid materials to ensure the overall stability and structural strength of the floating drum 4. The first buoyancy block 42 is sleeved on the limiting unit and is one of the main parts of the floating drum 4 that provide buoyancy. The first buoyancy block 42 is made of high-density lightweight materials (such as foamed plastics, polyurethane, etc.) to provide sufficient buoyancy to support the entire floating photovoltaic system. The connecting piece 43 is also sleeved on the limiting unit and is located between the first buoyancy block 42 and the second buoyancy block 44. The connecting piece 43 not only plays a connecting role, combining the various parts of the floating drum 4 into a whole, but also provides a connection point with the support frame 3, so that the floating drum 4 can stably support the entire system. The second buoyancy block 44 is sleeved on the other end of the limiting unit and provides buoyancy together with the first buoyancy block 42. The design and material of the second buoyancy block 44 are consistent with the first buoyancy block 42 to ensure that the buoyancy of the entire floating drum 4 is evenly distributed.

[0039] The limiting unit includes two sets of limiting plates 41 and limiting support rods 45; The two groups of limit plates 41 are respectively arranged in parallel at the two ends of the limit strut 45 . The first buoyancy block 42 , the connecting piece 43 and the second buoyancy block 44 are sequentially sleeved on the limit strut 45 and are located between the two groups of limit plates 41 .

[0040] In this embodiment, two groups of limit plates 41 are respectively arranged in parallel at both ends of the limit strut 45, which play the role of limiting and fixing the position of the buoyancy block and the connecting piece 43. The limit plates 41 are made of rigid materials, such as metal or hard plastic, to ensure their structural strength and stability. The limit strut 45, as the core structure of the limit unit, provides a space for the buoyancy block and the connecting piece 43. The limit strut 45 may adopt a cylindrical design to facilitate the sliding installation of the buoyancy block and the connecting piece 43. At the same time, the limit strut 45 also plays the role of connecting the two groups of limit plates 41, so that the entire limit unit forms a stable whole.

[0041] The outer diameters of the two groups of limiting plates 41, the first buoyancy block 42, the connecting piece 43 and the second buoyancy block 44 are the same.

[0042] The first buoyancy block 42 and the second buoyancy block 44 have the same structure, both of which are sleeve structures, and the surface of which is a continuously undulating plane structure.

[0043] In this embodiment, the surface of the buoyancy block is a continuously undulating plane structure, which increases the contact area between the buoyancy block and the water surface. A larger contact area means that the buoyancy block can more effectively utilize the buoyancy of the water, thereby providing greater support. The continuously undulating plane structure helps to reduce the swaying and tilting of the buoyancy block in the water. When external forces such as waves act on the buoyancy block, the undulating surface can disperse and absorb these forces, thereby reducing the risk of the buoyancy block rolling or tilting.

[0044] A buffer plate 46 is provided on the connecting piece 43 , and a surface of the buffer plate 46 is higher than a surface of the connecting piece 43 . Ends of the first buoyancy block 42 and the second buoyancy block 44 are both in contact with the buffer plate 46 .

[0045] In this embodiment, the buffer plate 46 is generally designed as a plate-like structure with a certain thickness and rigidity, and its material may be selected from materials that can resist external impact and wear, such as metal, hard plastic or composite materials. When the buoyancy block shakes or collides under external forces such as waves, the buffer plate 46, as the first line of defense, can absorb and disperse the impact force, thereby protecting the connecting piece 43 from direct impact.

[0046] In summary, the present invention provides a platform structure for an offshore floating photovoltaic module. By deploying the photovoltaic module module 1 on the sea surface in a manner of connecting with a float 4, the difficulty of installation is effectively reduced. The connection through the float 4 facilitates assembly, disassembly and rearrangement at sea, thereby improving the flexibility and maintainability of the system. The lightweight design of the float 4 can reduce the load on the platform, reduce material costs and construction difficulties, and improve energy conversion efficiency and photovoltaic power generation. The present invention focuses on lightweight and platform modularization, which can not only improve the economy and reliability of the floating photovoltaic system, but also has important significance for promoting the development of sustainable energy.

[0047] Example 2 This embodiment also provides a method for installing a platform structure of an offshore floating photovoltaic assembly, based on the above-mentioned platform structure of an offshore floating photovoltaic assembly, comprising the following steps: Several photovoltaic modules 2 are respectively mounted on several supporting frames 3. Each supporting frame 3 is used to support and fix one or more photovoltaic modules 2, ensuring that the photovoltaic modules 2 can be stably placed on the supporting frame 3 and maintain good power generation efficiency.

[0048] During the installation process, it is necessary to ensure that the connection between the photovoltaic module 2 and the support frame 3 is firm and reliable to avoid loosening or falling off during subsequent use.

[0049] The combination of several photovoltaic modules 2 and a supporting frame 3 is called a photovoltaic module 1. Each photovoltaic module 1 has a certain power generation capacity and structural stability, and can be used alone or in combination.

[0050] Several photovoltaic module modules 1 are laid flat on the water surface to form a large-area photovoltaic power generation platform. The bottom sides of adjacent photovoltaic module modules 1 are connected by several floating cylinders 4. The floating cylinders 4 not only play a connecting role, but also provide a certain buoyancy for the entire platform, so that it can float stably on the water surface.

[0051] During the installation process, it is necessary to ensure that the connection between each photovoltaic module 1 and the floating tube 4 is firm and reliable to avoid loosening or falling off due to external factors such as wind and waves. At the same time, the position and posture of the platform structure need to be adjusted according to actual needs to ensure that it can receive solar energy to the greatest extent and maintain good power generation efficiency.

[0052] In summary, the present embodiment provides a method for installing a platform structure of an offshore floating photovoltaic module, by installing the photovoltaic module 2 on a support frame 3 to form a photovoltaic module module 1, so that the installation process is more modular. This modular design simplifies the installation steps, reduces the difficulty of installation, and improves work efficiency. At the same time, it makes the arrangement and connection of the photovoltaic module 2 more flexible and can be adjusted according to actual needs. Adjacent photovoltaic module modules 1 are connected by a float 4 to form a stable offshore floating platform structure. The float 4 not only provides buoyancy, but also enhances the stability and wind and wave resistance of the platform structure. The platform can operate stably in harsh marine environments and ensure the power generation efficiency of the photovoltaic module 2.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
