[0005] According to an embodiment of the present invention, the floating platform is formed by splicing a plurality of hollow tubes, and the hollow tubes are spliced ​​in the main axis direction and in a direction perpendicular to the main axis direction.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Figure 1-Figure 3 As shown, a water surface solar power generation floating device according to an embodiment of the present utility model is described.

[0030] like Figure 1-Figure 3As shown, the present invention proposes a floating device for solar power generation on the water surface, comprising: a floating platform 10, a plurality of straps 20, and a plurality of floating panels 30. The floating platform 10 is laid on the plurality of floating panels 30, and the floating platform 10 and the floating panels 30 are fixedly connected by the straps 20, so that the floating panels 30 float on the water surface. This structural design is for installing solar panels, and the solar panels are installed on the floating platform 10. The design of the floating panels 30 is, on the one hand, to stably support the floating platform 10 and the solar panels installed on the floating platform 10 through buoyancy, and on the other hand, to achieve normal operation under water depth and wind conditions, thereby ensuring the stability of the solar panels on the water surface environment. The design of the straps 20 is to achieve the bundling and fixation of the floating platform 10, making the structure compact and stable. Through this structural design, the application scenario of solar power generation is realized, so that water surface resources are effectively utilized; wherein, multiple floating plates 30 are laid on the water surface in a straight line at intervals, and multiple floating plates 30 are arranged along the main axis direction of the floating platform 10. When the extension length of the floating platform 10 in the main axis direction increases, the number of the floating plates 30 increases accordingly; when the extension length of the floating platform 10 in the main axis direction decreases, the number of the floating plates 30 decreases accordingly.

[0031] Among them, the main axis direction of the floating platform 10 in the present invention refers to the extension direction of the longest side of the platform under normal use. The increase or shortening of the length of the main axis direction of the floating platform 10 is adjusted according to the actual water depth and wind and wave conditions to ensure the stability of the floating platform 10.

[0032] When the water depth increases and the wind and waves become stronger, in order to ensure the stability of the floating platform 10 on the water surface, the length of the floating platform 10 in the main axis direction needs to be increased. In this case, the length can be increased by adding a floating platform 10 on the basis of the original floating platform 10. At the same time, as the length changes, the number of floating plates 30 needs to be increased accordingly. For example, if the length increases, it is necessary to add more floating plates 30 to enhance the stability of the platform and prevent excessive shaking or tilting in harsh environments. Conversely, when the water depth decreases and the wind and waves weaken, the length of the floating platform 10 in the main axis direction is shortened, and the number of floating plates 30 is correspondingly reduced. For example, the floating platform 10 can be reduced on the basis of the original floating platform 10 to achieve a shortening of the length, thereby reducing costs and resource consumption while ensuring stability. It can be seen that the stability and reliability of the floating platform 10 in various environments are effectively ensured.

[0033] According to the floating device for water surface solar power generation according to an embodiment of the present invention, the floating plate 30 stably supports the floating platform 10 and the solar panel through buoyancy, and the strap 20 securely connects the floating platform 10 to the floating plate 30, making the entire structure compact and stable. The floating plates 30 are laid out in a straight line at intervals and arranged along the main axis of the floating platform 10. When the length of the floating platform 10 extending in the main axis direction changes, the number of floating plates 30 is adjusted accordingly, ensuring that no matter how the size of the floating platform 10 changes, there is sufficient buoyancy support and a stable structure, thereby providing a stable installation base for the solar panel, making it less susceptible to shaking due to water surface fluctuations and wind, ensuring that the solar panel can operate stably in the water surface environment, and improving power generation efficiency and equipment life. The design of the floating plate 30 utilizes buoyancy support on the one hand, and can operate normally under water depth and wind conditions on the other. The combination of multiple floating plates 30 can adjust the number according to actual conditions to adapt to different water conditions and wind environments. When encountering greater water depths or strong winds, the number of floating plates 30 can be increased to enhance stability; conversely, the number of floating plates 30 can be reduced. The structure can be flexibly adjusted to adapt to various complex water surface environments, allowing the solar power generation floating device to operate normally under different water depths and wind conditions, thereby expanding its scope of application. By installing the solar panels on the floating platform 10 and utilizing the structural design of the floating plates 30 and the straps 20, it can operate stably on the water surface, fully utilizing the vast water surface space without occupying land resources. As the extension length of the floating platform 10 changes in the main axis direction, the number of floating plates 30 is adjusted accordingly, allowing the entire device to be flexibly arranged according to actual needs, maximizing the use of water surface resources, achieving effective utilization of water surface resources, providing a new application scenario for solar power generation, and solving the problem of tight land resources.

[0034] According to an embodiment of the present invention, Figure 1 As shown, the floating platform 10 is spliced ​​together by a plurality of hollow tubes 101 , which are spliced ​​in the main axis direction and in a direction perpendicular to the main axis direction to enhance the structural strength and stability of the floating platform 10 in different directions and meet various usage requirements.

[0035] Here, the "orthogonal direction" refers to a direction at a 90-degree angle to the main axis. Specifically, when the water depth is deep and the waves are strong, multiple hollow tubes 101 are spliced ​​in the main axis direction to extend the floating platform 10. At the same time, hollow tubes 101 can also be spliced ​​in a direction orthogonal to the main axis direction to enhance the stability and load-bearing capacity of the floating platform 10 in complex environments. When the water depth is shallow and the waves are mild, the number of hollow tubes 101 spliced ​​in the main axis direction is reduced, and correspondingly, the number of hollow tubes 101 spliced ​​in a direction orthogonal to the main axis direction is also reduced to adapt to a gentle operating environment, reducing resource consumption and costs while ensuring stability.

[0036] In some embodiments, the hollow tube 101 is made of aluminum alloy; or glass fiber reinforced material FRP.

[0037] The hollow tube 101 is made of a corrosion-resistant, waterproof, lightweight material. Specifically, the hollow tube 101 is made of an aluminum alloy material, or may be made of a glass fiber reinforced material FRP.

[0038] When hollow tube 101 is made of aluminum alloy, aluminum alloy has a high strength-to-weight ratio. This means that while providing the strength to support floating platform 10 and the solar panels thereon, it does not add excessive weight to the overall structure, thereby ensuring the stability and maneuverability of floating platform 10 in water. Aluminum alloy also has excellent corrosion resistance. During long-term use in water, it can resist water erosion and corrosion from existing chemicals, extending the service life of hollow tube 101 and floating platform 10.

[0039] When the hollow tube 101 is made of glass fiber reinforced material FRP, FRP has excellent corrosion resistance. It can be used for a long time in various water environments, including highly corrosive environments such as seawater, without being easily damaged by corrosion. It is particularly suitable for structures such as floating platforms 10 that are in contact with water for a long time. Glass fiber reinforced material FRP has good strength and rigidity, providing sufficient strength to support the floating platform 10, and is not easily deformed when subjected to external forces, ensuring the stability of the floating platform 10. Glass fiber reinforced material FRP has a lightweight function. Compared with some traditional metal materials, FRP is lighter, which reduces the overall weight of the floating platform 10 and reduces the buoyancy requirements. It is also convenient for transportation and installation.

[0040] The hollow circular tube can also be made of the middle section of bamboo that has been treated with anti-corrosion and anti-termite treatment.

[0041] According to an embodiment of the present invention, in order to achieve good buoyancy and stability of the floating plate 30 in a water environment, the material of the floating plate 30 is EPP; or, the material of the floating plate 30 is bio-based foam; or, the material of the floating plate 30 is polylactic acid foam.

[0042] Specifically, when the floating plate 30 is made of EPP (expanded polypropylene), its low density gives it excellent buoyancy, providing stable support for the entire device. Its closed-cell structure ensures it does not absorb water, maintaining excellent buoyancy and stability in aquatic environments. EPP also offers excellent impact resistance, effectively protecting the solar power generation equipment from wind, waves, and floating objects. Furthermore, EPP's UV resistance and high and low temperature resistance ensure its operation in a variety of climates, extending the device's service life.

[0043] The floating plate 30 is made of bio-based foam, a renewable resource, reducing dependence on fossil fuels and environmental impact. Its excellent buoyancy, water resistance, and corrosion resistance enable stable operation on the water surface. It is also biodegradable under certain conditions, providing an option for future environmentally friendly disposal.

[0044] The floating plate 30 is made of polylactic acid foam, a material with environmental advantages that reduces the environmental pollution caused by traditional plastics. Its strength and toughness allow it to withstand the stress and impact of water, providing stable support for solar power generation equipment. Its ease of processing allows for flexible manufacturing of the floating plate 30, meeting diverse design requirements. Furthermore, its excellent weather resistance ensures the long-term stability of the device in aquatic environments.

[0045] According to one embodiment of the present invention, in order to tightly fix the spliced ​​multiple hollow tubes 101 together to form a floating platform 10, the strap 20 is in the shape of an elongated strip and surrounds the surface of the floating platform 10 at intervals, wherein the two ends of the strap 20 are fixed to the floating plate 30. Since the floating platform 10 after splicing is in the shape of a plate, the strap 20 is in the shape of an elongated strip, so that the two are compatible and can be tied more firmly. The strap 20 surrounds the surface of the floating platform 10, and its two ends are fixed to the floating plate 30. In other words, the strap 20 binds the spliced ​​hollow tubes 101 together, and at the same time, the two ends are bent along the edge of the floating platform 10 to form a bent portion, and the bent portion is fixed to the floating plate 30, thereby achieving fixed installation of the floating platform 10.

[0046] According to one embodiment of the present invention, in order to achieve real-time angle adjustment of the solar panels placed on the floating platform 10, the surface solar power generation floating device also includes: at least two first adjustment structures 40, which are arranged at intervals on the side of the floating platform 10 facing away from the water surface, and the first adjustment structures 40 are fixed on the straps 20.

[0047] In some embodiments, in order to achieve normal operation of the solar panel, a ring is provided on the first adjustment structure 40, a bearing 401 is provided inside the ring, a cylindrical core shaft 402 is provided on the bearing 401, and a square hole is opened on the cylindrical core shaft 402 for inserting the solar panel and fixing it with fasteners.

[0048] In some embodiments, in order to achieve precise angle adjustment of the solar panel during normal operation, the surface solar power generation floating device also includes: at least two second adjustment structures 41, which are arranged at intervals on the side of the floating platform 10 facing away from the water surface, and the second adjustment structures 41 are fixed on the strap 20.

[0049] The material of the strap 20 is nylon material, polyester fiber material, or polypropylene material.

[0050] When the nylon strap 20 is made of material, it is strong enough to withstand significant tension, ensuring a stable connection between the floating platform 10 and the floating plate 30 despite external forces such as currents and waves. Nylon also offers excellent corrosion resistance, adapting to the aquatic environment and resisting damage over long periods of use. Furthermore, its flexibility makes it easy to operate and adapts to the needs of securing components of varying shapes and sizes.

[0051] When the polyester fiber strap 20 is made of polyester fiber, it is strong and durable, able to withstand long-term use and external impact, making it ideal for use in floating solar power generation devices on the surface. Its excellent waterproofness prevents damage from contact with water, ensuring the stable performance of the strap 20. Furthermore, the polyester fiber strap 20 is lightweight and easy to operate, making it convenient to carry and install, thereby improving work efficiency.

[0052] When the strap 20 is made of polypropylene, it is highly water-resistant and will not deform or damage even after prolonged immersion in water, making it ideal for aquatic environments. It also exhibits a certain degree of corrosion resistance to chemicals such as acids and alkalis, and remains stable under varying water conditions. Furthermore, polypropylene is a low-cost material, which can reduce product costs, and its excellent processability makes it suitable for various applications.

[0053] In some embodiments, to adjust the height of the solar panel, the second adjustment structure 41 is configured as a hydraulic lift rod, with a support plate 411 mounted above the hydraulic lift rod, and the solar panel is mounted on the support plate 411. The support plate 411 has threaded holes, and the solar panel is fastened to the threaded holes by fasteners.

[0054] According to an embodiment of the present invention, in order to ensure the normal operation of the solar panel, the solar panel is electrically connected to the floating platform 10 .

[0055] The installation method of the floating solar power generation device on the water surface uses a strap 20 for fixing the hollow tube 101 in the floating platform 10. After the floating platform 10 and the floating plate 30 are tightly fixed together by the strap 20, they are then fixed to piles on the shore by ropes 42. At the same time, the entire floating device is fixed to a specific position on the water surface using an anchor chain and an anchor block through a circular hole in the floating platform 10 to prevent it from drifting with wind and waves.

[0056] According to the size and weight of the floating platform 10 and the number of floating plates 30 , at least two-thirds of the floating platform 10 should be exposed above the water surface after installation.

[0057] It should be noted that Figure 1In the example, the support plate is labeled as 411 (41), where 411 represents that the support plate is a component of the second adjustment structure (labeled as "41"). Similarly, the support plate is labeled as 402 (40), where 402 represents that the cylindrical core shaft is a component of the first adjustment structure (labeled as "40").

Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is at a higher level than the second feature.
