Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic floating platform assembly, and specifically relates to an offshore photovoltaic floating platform assembly structure and an assembly method thereof. Background Art

[0002] An offshore photovoltaic floating platform is a technology that deploys a photovoltaic power generation system on the ocean, aiming to utilize the vast ocean space for solar power generation. With the continuous increase in the global demand for renewable energy, land-based photovoltaic power generation is restricted by land resources, lighting conditions, and environmental factors, while offshore photovoltaic floating platforms provide a new solution. An offshore photovoltaic floating platform is a power generation system that installs photovoltaic modules on a floating platform, usually deployed in waters such as offshore areas or lakes. Its core idea is to utilize the water area space to solve the problem of land shortage faced by land-based photovoltaic power generation. The technology of offshore photovoltaic floating platforms was first studied in the early 21st century. In recent years, with the maturity of technology and the reduction of costs, it has gradually entered the commercial application stage. Countries such as the Netherlands, Japan, and China are in the leading position in the field of offshore photovoltaic floating platforms and have built multiple demonstration projects. Offshore photovoltaic floating platforms have the following advantages compared with land-based photovoltaic systems: High space utilization rate: The ocean area is vast, especially suitable for areas with scarce land resources. Good cooling effect: The cooling effect of water on photovoltaic panels can improve the power generation efficiency, especially in high-temperature environments. Reduced land occupation: Avoid competing with agriculture, urban construction, etc. for land resources. Environmentally friendly: Offshore photovoltaic floating platforms can reduce water surface evaporation and inhibit the growth of algae, having a certain positive effect on the ecological environment. High power generation efficiency: The sea surface reflectivity is relatively high, which can increase the light absorption efficiency of photovoltaic panels.

[0003] Existing offshore photovoltaic floating platforms usually adopt a fixed design, and the connection method between modules is relatively complex, resulting in difficult disassembly. This leads to high maintenance costs: Difficult disassembly makes the later maintenance and repair work complicated, increasing the maintenance costs. Poor flexibility: The floating platform cannot be quickly adjusted or relocated according to usage requirements or sea conditions, restricting its application flexibility. The floating platform needs to have good anti-wave and long-term stability to ensure the safe operation of the photovoltaic system.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs an offshore photovoltaic floating platform assembly structure and an assembly method thereof, solving the above technical problems. Summary of the Invention

[0022] An assembling method for an offshore photovoltaic floating platform, which is used in cooperation with the above-mentioned assembling structure of an offshore photovoltaic floating platform. The steps of the method are as follows:

[0023] S1: Before starting to assemble the offshore photovoltaic floating platform, first, a detailed basic design is required. Select a suitable assembling mechanism according to the geographical and climatic conditions of the assembling sea area. When the sea surface is relatively calm and the installation area of the photovoltaic floating platform is relatively dense, select the buoyancy plate mechanism provided with a mounting block and a connecting block for assembly. When there is a certain amount of wind and waves on the sea surface and the installation area of the photovoltaic floating platform is relatively wide, select the buoyancy plate mechanism provided with an inclined assembling block for assembly. In addition, auxiliary materials such as an anchoring system and cables need to be prepared. After the design is completed, all materials need to be inspected for quality to ensure compliance with the design requirements;

[0024] S2: In the factory, the buoyancy plate mechanism with different types of assembly mechanisms is prefabricated according to the selection. The buoyancy plate mechanism is manufactured by injection molding or welding process to ensure its sealing and buoyancy. After the prefabrication is completed, the preliminary assembly of the module is carried out to check whether the connection between the components is firm to ensure the integrity of the module;

[0025] S3: During the assembly process, the oblique assembly ring is clamped in the middle of the oblique assembly double rings and fixed by the connecting bolts. The above operations are repeated in sequence to form a buoyancy plate mechanism matrix; the longitudinal limit block is clamped into the limit groove, and the horizontal insertion block is placed in the connecting block. And it is fixed by screwing screws into the stabilizing holes to form a buoyancy plate mechanism matrix;

[0026] S4: The prefabricated buoyancy plate mechanism matrix is transported to the target sea area by a large transport ship. During the transportation, fixing measures need to be taken to prevent the buoyancy plate mechanism matrix from being damaged by the turbulence at sea. After arriving at the target sea area, the positioning system is used for accurate offshore positioning. When positioning, factors such as ocean currents and wind direction need to be considered to ensure the accuracy of the installation position of the buoyancy plate mechanism. After positioning is completed, the anchoring system is used to fix the floating platform on the seabed;

[0027] S5: After the buoyancy plate mechanism is fixed, the telescopic assembly is installed on the control assembly and fixed with fixing screws, and the photovoltaic panel is installed. The photovoltaic panel is usually made of lightweight and high-strength materials. During installation, the photovoltaic panel is fixed on the fixed rail on the buoyancy plate mechanism to ensure that its angle and direction meet the design requirements to maximize the solar energy absorption efficiency; during the installation process, special tools and equipment such as cranes, screwdrivers, etc. are required to ensure the accuracy and firmness of the installation;

[0028] S6: After the photovoltaic panels are installed, make electrical connections. Connect the output cables of the photovoltaic panels to the junction box, and then transmit the electricity to the substation on the shore through the submarine cable. During the electrical connection process, it is necessary to strictly follow the electrical safety specifications to ensure the reliability and safety of the connection;

[0029] S7: After the photovoltaic floating platform is installed, the system is debugged. The debugging content includes checking the output power of the photovoltaic panels, the stability of the electrical connections, the firmness of the anchoring system, etc. During the debugging process, professional instruments and equipment, such as power meters and voltmeters, are used to ensure the normal operation of the system. After the debugging is completed, the photovoltaic floating platform is officially put into operation. During the operation, regular maintenance is required, including cleaning the surface of the photovoltaic panels, checking the electrical connections, and reinforcing the anchoring system.

[0030] The beneficial effects of the present invention are as follows:

[0031] (1) The design of the present invention significantly improves the deficiencies of existing offshore photovoltaic floating platforms in terms of disassembly, maintenance, and adaptability by introducing a variety of assembly mechanisms and flexible connection methods. By setting different assembly mechanisms (such as plug-in, snap-in, or bolt connection), the connection methods between buoyancy plate mechanisms are more diverse, and the most suitable connection method can be selected according to specific requirements. The modular design makes the assembly and disassembly process of the floating platform simpler, without the need for complex tools or equipment, reducing the operation difficulty. The convenient disassembly makes the later maintenance and repair work more efficient, reducing labor and time costs. The floating platform can be quickly adjusted or relocated according to usage requirements or sea conditions changes. For example, in areas with strong winds and waves, a more stable connection method can be replaced, or some modules can be quickly disassembled when maintenance is required.

[0032] (2) By setting an adjustable telescopic mechanism in the present invention, the tilting direction and angle of the photovoltaic panel can be quickly adjusted according to the sun position and sea area lighting conditions. By adjusting the angle of the photovoltaic panel in real time, the absorption efficiency of solar energy is maximized, especially in different seasons or weather conditions. In sea areas with large differences in lighting conditions, the angle of the photovoltaic panel can be flexibly adjusted to ensure the efficient operation of the system in different environments.

[0033] (3) The present invention can better adapt to the environmental conditions of different sea areas, reducing damage or performance degradation caused by environmental factors. By specifically selecting different assembly mechanisms, the durability of the floating platform in harsh environments is improved, extending the service life of the system. Reducing maintenance costs and deployment costs, improving the overall economy of the system. Improving operating efficiency: By quickly adjusting the angle of the photovoltaic panel and flexibly adapting to sea area conditions, the power generation efficiency is maximized. Expanding the application scope: The flexibility and adaptability of the floating platform enable it to be applied to more sea areas and environmental conditions, promoting the popularization of offshore photovoltaic technology. Sustainable development: By extending the service life and reducing maintenance requirements, resource waste is reduced, which conforms to the concept of sustainable development.

Detailed implementation manners

[0046] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0047] As Figures 1-9As shown in the figure, a floating photovoltaic buoy mechanism 4 assembly structure includes a photovoltaic panel 1, a fixing component 2, a telescopic component 3, a buoy mechanism 4, a control component 5, and an assembly mechanism 6. The fixing component 2 is installed under the photovoltaic panel 1 to fix the photovoltaic panel 1 and ensure its stability; the telescopic component 3 is installed under the fixing component 2 to adjust the height of the photovoltaic panel 1 relative to the buoy mechanism 4 through telescopic movement; the buoy mechanism 4 is placed on the water surface to provide buoyancy support for the entire buoy mechanism 4; the control component 5 is installed at the four corners of the buoy mechanism 4 to control the movement of the telescopic component 3 and the overall balance of the buoy mechanism 4; the assembly mechanism 6 is installed on the side of the buoy mechanism 4 to connect adjacent buoy mechanisms 4 to form an integral structure.

[0048] The telescopic components 3 on the same side can move up and down within the control component 5, thereby adjusting the height value of the photovoltaic panel 1 relative to the upper surface of the buoy mechanism 4. This design enables the photovoltaic panel 1 to be flexibly adjusted according to the sun's position, sea conditions, or lighting conditions, maximizing the solar energy absorption efficiency. The buoy mechanism 4 is arranged in a rectangular array or an oblique rectangular array. This layout not only improves the stability of the buoy mechanism 4 but also optimizes the space utilization rate, making the arrangement of the photovoltaic panels 1 more compact and efficient. Two adjacent buoy mechanisms 4 are connected by the assembly mechanism 6. The assembly mechanism 6 adopts a modular design, making the installation and disassembly of the buoy mechanism 4 more convenient and facilitating later maintenance and repair.

[0049] As Figure 3 shown in the figure, the fixing component 2 includes a fixing rail 21 and a connecting shaft 22; the fixing rail 21 is installed under the photovoltaic panel 1 to fix the photovoltaic panel 1 and ensure its stability. The design of the fixing rail 21 enables the photovoltaic panel 1 to be firmly installed on the buoy mechanism 4 and provides a basic support for adjusting the tilt angle and direction of the photovoltaic panel 1. The connecting shaft 22 is installed at the upper end of the telescopic component 3. The connecting shaft 22 is rotatable, enabling the photovoltaic panel 1 to be adjusted at multiple angles around the connecting shaft 22. By adjusting the length of the telescopic component 3, the height and tilt angle of the photovoltaic panel 1 relative to the buoy mechanism 4 can be changed, thereby achieving precise control of the tilt direction and angle of the photovoltaic panel 1. This design can not only adjust the angle of the photovoltaic panel 1 in real time according to the change of the sun's position to maximize the solar energy absorption efficiency but also adapt to the climate conditions of different sea areas. For example, in the case of strong winds and waves, the angle of the photovoltaic panel 1 can be adjusted to reduce wind resistance. In addition, the rotation function of the connecting shaft 22 makes the adjustment of the photovoltaic panel 1 more flexible and the operation more convenient, providing an important guarantee for the efficient operation of the floating photovoltaic buoy mechanism 4.

[0050] As Figure 3As shown, the telescopic component 3 includes a telescopic rod 31 and a fixing hole 32. The telescopic rod 31 is installed inside the control component 5 and can be telescopically adjusted as needed to adapt to different installation requirements. The fixing hole 32 is opened on the side of the telescopic rod 31 and has a precise design to ensure more stable connection with other components. The inner surface of the fixing hole 32 is provided with threads, which can cooperate with the fixing screw 54 to enhance the fastening force of the connection part and prevent the components from loosening due to vibration or external force. To ensure the balance of force, the opening direction of the fixing hole 32 is the same as the orientation of the fixing rail 21, ensuring more uniform force transmission and avoiding excessive local stress. Such a design optimizes the use stability in special environments such as the sea surface, enhances the firmness and wind resistance during the installation of the photovoltaic panel 1, improves the overall service life and performance stability of the equipment, and adapts to the complex and changeable installation environment. This structure not only improves the installation efficiency but also further enhances the reliability of the system.

[0051] As Figure 4 shown, the buoyancy plate mechanism 4 is designed with multiple key components, each of which is carefully conceived to ensure its stability, durability, and impact resistance on the water surface. The buoyancy plate body 41 is the core of the mechanism, placed above the water surface and undertaking the main function of buoyancy support. Its material is usually selected from materials with good buoyancy characteristics and corrosion resistance, such as special plastics or composite materials, to ensure the long-term stable floating of the buoyancy plate on the water surface.

[0052] To enhance the stability of both sides of the buoyancy plate, the structure of the side concave surface 42 is introduced in the design. The side concave surface 42 is located on both sides of the buoyancy plate body 41. By changing the flow direction of the water flow, it reduces the uneven pressure generated by the water surface fluctuation on both sides of the buoyancy plate, thereby improving the stability of the entire buoyancy plate mechanism 4 and avoiding the risk of tilting or capsizing.

[0053] The overflow groove 43 is arranged at the bottom and side of the buoyancy plate body 41 and plays an important guiding role. When the sea wave passes through the buoyancy plate, the overflow groove 43 can effectively guide part of the water flow through, thereby slowing down the impact force generated by the wave on the buoyancy plate, reducing the direct impact of the water flow on the buoyancy plate, and reducing the burden of the wave on the entire structure. This design can effectively improve the durability and impact resistance of the buoyancy plate under harsh sea conditions.

[0054] The buoyancy cavity 44 is opened inside the buoyancy plate body 41, and the cavity is filled with air or other light gases, thereby further enhancing the buoyancy of the buoyancy plate and ensuring its floating effect on the water surface. The support rod 45 is installed inside the buoyancy cavity 44, which plays a role in supporting the buoyancy plate body 41 and providing overall stability. The support rod 45 adopts a zigzag design, and this shape helps to improve the strength and stability of the structure, avoiding the risk of bending or breaking that is prone to occur in a single straight-line structure. The material of the support rod 45 is selected as metal, which has strong strength and corrosion resistance and can be used in the marine environment for a long time.

[0055] Overall, the design of the buoyancy plate mechanism 4 is reasonable and the functions are complementary. The coordinated use of each component ensures the stability of the structure under the influence of waves, wind and other external factors, and is suitable for various application occasions that require a water surface floating platform.

[0056] As Figure 7 shown, the control component 5 is an important part of the buoyancy plate mechanism 4, which is mainly used to adjust and fix the positions of the buoyancy plates to ensure its stability during use. The telescopic sleeves 51 are installed at the four corners of the buoyancy plate mechanism 4. Their function is to provide a moving space for the telescopic components and can adjust the height and angle of the buoyancy plate within a certain range. The telescopic holes 52 are opened inside the telescopic sleeves 51 and are of a through design. Such a structure enables the sleeves to perform corresponding telescopic adjustments in an environment with changing water levels to adapt to different installation requirements and water surface conditions.

[0057] The positioning holes 53 are located on the sides of the telescopic sleeves 51. In terms of design, they are convenient for cooperating with other connecting components to ensure the accurate fixation of the positions of the telescopic sleeves 51. The setting of the positioning holes 53 can effectively prevent the telescopic sleeves 51 from shifting during use and ensure their fixity. The fixing screws 54 are installed in the positioning holes 53. By tightening the screws, the positions of the telescopic sleeves 51 can be firmly fixed, thereby enhancing the stability of the buoyancy plate. The design of the entire control component 5 ensures that the buoyancy plate can maintain stability in different environments and avoids structural loosening or instability caused by fluctuations or external forces.

[0058] The inner surface of the positioning hole 53 is provided with a spiral groove. The positioning hole 53 is set to penetrate one side of the telescopic sleeve 51 and is opened to half of the depth on the other side in the same direction. With this setting, after the fixing screw 54 passes through the positioning hole 53 and the fixing hole 32, it will be fixed in the telescopic sleeve 51, improving the stability.

[0059] As Figure 6As shown, the assembly mechanism 6 is a key connecting and mounting component in the buoyancy plate mechanism 4. Its function is to ensure the stable assembly and position fixation of each component in the buoyancy plate mechanism 4 through precise fitting and structural design. The assembly mechanism 6 consists of an inclined assembly block 61, an inclined assembly ring 62, and an inclined double assembly ring 63. The inclined assembly block 61 is installed at the four corners of the buoyancy plate mechanism 4 as the basis for support and connection. Each inclined assembly block 61 has a certain inclined angle design, enabling more flexible installation and adjustment of each part of the buoyancy plate in space.

[0060] The inclined assembly ring 62 or the inclined double assembly ring 63 is installed at the top of the inclined assembly block 61, playing the role of connecting different components. In the diagonal direction of the buoyancy plate mechanism 4, the inclined assembly ring 62 and the inclined double assembly ring 63 are set in the same structural form to ensure the fitting and installation stability between them. The inclined assembly ring 62 is located in the middle of the assembly block, while the inclined double assembly ring 63 is installed at the upper and lower ends of the assembly block. This design enables the inclined assembly ring 62 to be exactly clamped in the middle of the inclined double assembly ring 63, forming a tight and firm connection. Through this ingenious structural design, the assembly mechanism 6 can not only enhance the overall stability of the buoyancy plate but also effectively reduce the looseness or displacement between components, ensuring the long-term stability of the buoyancy plate in practical applications.

[0061] The assembly mechanism 6 is an important part of the buoyancy plate mechanism 4, aiming to ensure the firm and efficient cooperation between each component through a precise connection and fixation mechanism, thereby improving the stability and durability of the entire system. The assembly mechanism 6 includes an installation block 64, a connection block 65, an insertion block 66, and a stability hole 67. The design of each component takes into account the dynamic pressure and external forces that the buoyancy plate may encounter during long-term floating on the water surface.

[0062] A method for assembling an offshore photovoltaic floating platform, which is used in conjunction with the above-mentioned assembly structure of an offshore photovoltaic floating platform. The steps of the method are as follows:

[0063] S1: Before starting the assembly of the offshore photovoltaic floating platform, detailed basic design is required first. According to the geographical and climatic conditions of the assembly sea area, select a suitable assembly mechanism 6. When the sea surface is relatively calm and the installation area of the photovoltaic floating platform is relatively dense, select the buoyancy plate mechanism 4 provided with the installation block 64 and the connection block 65 for assembly. When there are certain winds and waves on the sea surface and the installation area of the photovoltaic floating platform is relatively wide, select the buoyancy plate mechanism 4 provided with the inclined assembly block 61 for assembly. In addition, auxiliary materials such as an anchoring system and cables need to be prepared. After the design is completed, all materials need to be inspected for quality to ensure compliance with the design requirements;

[0064] S2: In the factory, the buoyancy plate mechanism 4 equipped with different types of assembly mechanisms 6 is prefabricated according to the selection. The buoyancy plate mechanism 4 is manufactured by injection molding or welding process to ensure its sealing and buoyancy. After the prefabrication is completed, the module is preliminarily assembled to check whether the connection between the components is firm to ensure the integrity of the module;

[0065] S3: During the assembly process, the oblique assembly ring 62 is clamped in the middle of the oblique assembly double ring 63 and fixed by the connecting bolt. The above operations are repeated in sequence to form the buoyancy plate mechanism 4 matrix; the longitudinal limit block 642 is clamped into the limit groove 641, and the transverse insertion block 66 is placed in the connecting block 65. The buoyancy plate mechanism 4 matrix is formed by screwing screws into the stabilizing holes 67;

[0066] S4: The prefabricated buoyancy plate mechanism 4 matrix is transported to the target sea area by a large transport ship. During the transportation, fixing measures need to be taken to prevent the buoyancy plate mechanism 4 matrix from being damaged by the turbulence at sea. After arriving at the target sea area, the positioning system is used for accurate marine positioning. When positioning, factors such as ocean currents and wind direction need to be considered to ensure the accuracy of the installation position of the buoyancy plate mechanism 4. After the positioning is completed, the anchoring system is used to fix the floating platform on the seabed;

[0067] S5: After the buoyancy plate mechanism 4 is fixed, the telescopic component 3 is installed on the control component 5 and fixed by the fixing screws 54, and the photovoltaic panel 1 is installed. The photovoltaic panel 1 is usually made of light and high-strength materials. During installation, the photovoltaic panel 1 is fixed on the fixed rail 21 on the buoyancy plate mechanism 4 to ensure that its angle and direction meet the design requirements to maximize the solar energy absorption efficiency; during the installation process, special tools and equipment, such as a crane, a screwdriver, etc., are required to ensure the accuracy and firmness of the installation;

[0068] S6: After the photovoltaic panel 1 is installed, make electrical connections. Connect the output cable of the photovoltaic panel 1 to the junction box, and then transmit the electric energy to the substation on the shore through the submarine cable. During the electrical connection process, it is necessary to strictly follow the electrical safety specifications to ensure the reliability and safety of the connection;

[0069] S7: After the photovoltaic floating platform is installed, the system is debugged. The debugging content includes checking the output power of the photovoltaic panel 1, the stability of the electrical connection, the firmness of the anchoring system, etc. During the debugging process, professional instruments and equipment, such as power meters and voltmeters, are used to ensure the normal operation of the system. After the debugging is completed, the photovoltaic floating platform is officially put into operation. During the operation, regular maintenance is required, including cleaning the surface of the photovoltaic panel 1, checking the electrical connection, and reinforcing the anchoring system.

[0070] During the working process of the present invention,

[0071] Before starting the assembly of the offshore photovoltaic floating platform, select a suitable assembly mechanism 6 according to the geographical and climatic conditions of the assembly sea area. When the sea surface is relatively calm and the installation area of the photovoltaic floating platform is relatively dense, the buoyancy plate mechanism 4 provided with the installation block 64 and the connection block 65 is selected for assembly. When there is a certain amount of wind and waves on the sea surface and the installation area of the photovoltaic floating platform is relatively wide, the buoyancy plate mechanism 4 provided with the oblique assembly block 61 is selected for assembly. In addition, auxiliary materials such as an anchoring system and cables need to be prepared;

[0072] Perform pre-assembly on a transport ship or on land. The oblique assembly ring 62 is clamped in the middle of the oblique assembly double ring 63 and fixed by a connecting bolt. Repeat the above operations in sequence to form a matrix of the buoyancy plate mechanism 4; or the limiting block 642 in the longitudinal direction is clamped into the limiting groove 641, and the transverse insertion block 66 is placed in the connection block 65. And it is fixed by screwing a screw into the stabilizing hole 67 to form a matrix of the buoyancy plate mechanism 4; transport the prefabricated matrix of the buoyancy plate mechanism 4 to the target sea area by a large transport ship, install the telescopic assembly 3 on the control assembly 5 and fix it by the fixing screw 54, and start installing the photovoltaic panel 1. Fix the photovoltaic panel 1 on the fixing rail 21 on the buoyancy plate mechanism 4 to ensure that its angle and direction meet the design requirements to maximize the absorption efficiency of solar energy.

[0073] Embodiment 2:

[0074] For a working environment with a relatively small working sea area and relatively stable climate, the assembly mechanism 6 can adopt another structure, which is beneficial to saving space;

[0075] The installation block 64 is installed on the two sides of the buoyancy plate mechanism 4 as a basic component for support and fixation to ensure that the buoyancy plate will not displace or tilt in different working environments. The connection block 65 is installed on the side of the buoyancy plate mechanism 4 in another direction and is responsible for connecting different parts of the buoyancy plate to form a stable whole. The insertion block 66 is installed on another side of the buoyancy plate mechanism 4, and it acts together with the installation block 64 and the connection block 65 to ensure the tight connection and stable support between the various components of the buoyancy plate. The stabilizing hole 67 is opened between the upper part of the connection block 65 and the insertion block 66. By inserting different connecting elements, the relative positions between the various components can be effectively fixed and adjusted, thereby improving the stability of the overall structure.

[0076] In addition, the design of the mounting block 64 also includes a limiting groove 641 and a limiting block 642. The cross-sectional shapes of the limiting groove 641 and the limiting block 642 are isosceles trapezoids, ensuring precise fit and firm connection between the two components. The limiting groove 641 is linearly arrayed on the side surface of the mounting block 64, while the limiting block 642 is linearly arrayed on the other side surface of the mounting block 64, ensuring that when the component is inserted, the limiting block 642 can tightly engage into the limiting groove 641, preventing unnecessary sliding or loosening of the component. This design enables the buoyancy plate to maintain a stable posture and fixed position even under large external forces or fluctuations during use.

[0077] Overall, the assembly mechanism 6 ensures the stability of the buoyancy plate in various complex water surface environments through diversified connection and fixing methods, can effectively cope with the influence of external factors such as waves and wind, and improves the safety and reliability of the system.
