These existing offshore photovoltaic platforms are mainly used in shallow coastal waters and are suitable for low sea state environment. Compared with shallow waters, deep sea photovoltaic resources have huge reserves and great development potential. However, the sea state condition in deep sea is more severe, which puts higher requirements on the design and performance of photovoltaic platforms.

[0003] The existing offshore floating photovoltaic platforms have many problems when facing deep sea environment. First, these platforms have poor adaptability to deep sea environment and are difficult to cope with complex and changeable sea state conditions. Second, under the action of waves, the platform has large motion response, which affects the stability and power generation efficiency of the photovoltaic system. In addition, due to the particularity of deep sea environment, the manufacturing and maintenance cost of existing platforms is high, and the economy is poor.

[0004] In order to efficiently develop deep sea photovoltaic energy, it is urgent to develop a new type of offshore floating photovoltaic power generation platform. The platform should have the following characteristics: small motion response under wave action, stable, easy to maintain, reduce operating cost, good adaptability to deep sea environment, and can cope with complex and changeable sea state conditions. At the same time, how to reduce the manufacturing cost of the platform and improve its economic feasibility also needs to be considered. UTILITY MODEL CONTENT

[0033] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0034] Referring to Figures 1 to 11 The embodiments of the present application disclose a sea floating photovoltaic power generation platform, comprising a plurality of photovoltaic power generation modules 1 arranged in an array and a connector 2 connecting two adjacent photovoltaic power generation modules 1; the photovoltaic power generation module 1 comprises a photovoltaic panel 11, a photovoltaic support 12, a buoyancy platform 13 and a locking mechanism 14, the photovoltaic panel 11 is fixedly connected to the photovoltaic support 12, and the photovoltaic support 12 is connected to the buoyancy platform 13 through the locking mechanism 14; the connector 2 comprises two detachably connected connecting hooks 21, both of which are provided with a spherical hinge joint 22, and the photovoltaic power generation module 1 is provided with a spherical hinge joint seat 23, and the spherical hinge joint 22 is universally hinged in the spherical hinge joint seat 23.

[0035] As can be known from the above, the photovoltaic power generation module 1 is arranged in an array, which can effectively utilize the surface space of the sea and improve the photovoltaic power generation efficiency. The photovoltaic panel 11 is fixedly connected through the photovoltaic support 12, and the photovoltaic support 12 is connected with the buoyancy platform 13 through the locking mechanism 14, thereby ensuring the stability of the photovoltaic panel 11 in the marine environment. The connector 2 adopts a detachable connecting hook 21, and the connecting hook 21 is provided with a spherical hinge joint 22, which is universally hinged with a spherical hinge joint seat 23 on the photovoltaic power generation module 1, so that the photovoltaic power generation module 1 can be flexibly adjusted in position under the action of ocean waves, thereby reducing the impact of waves on the photovoltaic panel 11. The photovoltaic power generation module 1 and the connector 2 arranged in an array can stably operate in the marine environment, and the design of the locking mechanism 14 and the spherical hinge joint 22 can effectively reduce the impact of waves on the photovoltaic panel 11, thereby improving the efficiency and stability of photovoltaic power generation. The technical scheme has better adaptability and maintainability in deep-sea environment, and can efficiently develop deep-sea photovoltaic energy.

[0036] Referring back to Figure 10 and Figure 11 In this embodiment, the side of the connecting hook 21 away from the spherical hinge joint 22 is provided with a hook groove 24 and a hook tongue 25, the hook tongue 25 is hinged on the connecting hook 21 and used for locking the hook groove 24 of another connecting hook 21, and the connecting hook 21 is further provided with a locking pin 26 used for limiting the lock tongue. Specifically, the design of the hook groove 24 and the hook tongue 25 enables two connecting hooks 21 to be quickly connected and detached through the cooperation of the hook tongue 25 and the hook groove 24. The hook tongue 25 is hinged on the connecting hook 21, so that the hook tongue 25 can rotate within a certain range, thereby facilitating the locking with the hook groove 24 of another connecting hook 21. The arrangement of the locking pin 26 further enhances the stability of the connection, and through the limiting of the lock tongue, the hook tongue 25 is prevented from accidentally detaching from the hook groove 24 during the connection process, thereby ensuring the firmness of the connection. When unlocking, the locking pin 26 is only lifted upward, and the hook tongues 25 of the two connectors 2 can be unlocked and separated.

[0037] Referring back to Figure 4 and Figure 5 In this embodiment, the locking mechanism 14 includes a lock sleeve 141, a rotating shaft 142 and a locking pin 143, the locking pin 143 is fixedly connected on the rotating shaft 142, the rotating shaft 142 is rotatably arranged in the lock sleeve 141 and protrudes out of the lock sleeve 141, the lock sleeve 141 is fixedly connected with the photovoltaic support 12, and the buoyancy platform 13 is provided with a clamping groove 144 for embedding the locking pin 143. Specifically, the lock sleeve 141 is used for limiting the rotating shaft 142, so that the rotating shaft 142 can freely rotate in the lock sleeve 141. One end of the rotating shaft 142 is fixedly connected with the locking pin 143, and the shape and size of the locking pin 143 are matched with the clamping groove 144 on the buoyancy platform 13, so that the locking pin 143 can be embedded in the clamping groove 144, thereby realizing the fixed connection of the photovoltaic support 12 and the buoyancy platform 13.

[0038] In this embodiment, the clamping pin 143 is formed of magnetizable material, and the clamping slot 144 is provided with a magnet 145 for magnetically attracting the clamping pin 143. The magnetizable material can be a magnetic metal such as iron, nickel, cobalt, or an alloy thereof, and the magnet 145 can be a permanent magnet. Specifically, the clamping pin 143 is fixed in the clamping slot 144 by the magnetic attraction of the magnet 145, thereby achieving stable connection of the photovoltaic support 12. As a preferred implementation, the magnet 145 can be embedded in the bottom or sidewall of the clamping slot 144 to ensure that the clamping pin 143 can be effectively attracted when embedded in the clamping slot 144. When the platform is being maintained, if the photovoltaic support 12 or the photovoltaic panel 11 fails or is damaged, an external magnetic field can be applied to demagnetize the magnet 145 and unlock the locking mechanism 14, so that the photovoltaic support 12 can be separated from the buoyant platform 13, thereby achieving the replacement of the photovoltaic support 12 without replacing the buoyant platform 13.

[0039] In this embodiment, the clamping slot 144 has two and is arranged radially spaced apart. By providing two clamping slots 144, the clamping pin 143 can be fixed at two different positions, thereby enhancing the connection strength between the photovoltaic support 12 and the buoyant platform 13. This design not only effectively disperses the force, but also reduces the shaking of the photovoltaic support 12 under the action of waves, thereby improving the stability of the overall structure. In addition, the shape and depth of the clamping slot 144 can also be optimized according to the size and material properties of the clamping pin 143 to ensure that the clamping pin 143 can be firmly embedded in the clamping slot 144, avoiding loosening or falling off in severe sea conditions.

[0040] Continuing to refer to Figure 3 In this embodiment, the photovoltaic support 12 includes a support tray 121, the support tray 121 is fixedly connected with the lock sleeve 141, and the support tray 121 is connected with a support column 122 for tilting the photovoltaic panel 11, and the two sides of the photovoltaic panel 11 are connected to the support tray 121 and the support column 122, respectively. Specifically, the support tray 121 serves as the basic structure of the photovoltaic support 12, and its fixed connection with the lock sleeve 141 ensures the stability of the photovoltaic support 12. The provision of the support column 122 allows the photovoltaic panel 11 to be tilted at an angle, which helps to improve the efficiency of the photovoltaic panel 11 in receiving sunlight. The two sides of the photovoltaic panel 11 are connected to the support tray 121 and the support column 122, respectively, which not only enhances the fixation of the photovoltaic panel 11, but also helps to disperse the force on the photovoltaic panel 11, thereby improving the stability and durability of the entire photovoltaic power generation module 1. As a preferred implementation, the support tray 121 can be made of high-strength lightweight material to reduce the overall weight and improve the wind and wave resistance.

[0041] In this embodiment, the angle between the photovoltaic panel 11 and the support tray 121 is 20 degrees. Specifically, the angle between the photovoltaic panel 11 and the support tray 121 is set to 20 degrees, which is designed to optimize the efficiency of the photovoltaic panel 11 in receiving sunlight. By tilting the photovoltaic panel 11, it conforms to the best installation angle in most areas of Zhejiang Province, which can increase the effective receiving area of the photovoltaic panel 11 at different times of the day, thereby improving the efficiency of the photovoltaic conversion. In addition, the 20-degree inclination angle also helps to reduce the accumulation of dust and moisture on the surface of the photovoltaic panel 11, reducing the frequency and cost of maintenance.

[0042] Continuing to refer to Figure 5 In this embodiment, the buoyant platform 13 includes a support platform 131 and a float 132, the support platform 131 is provided with a clamping slot 144, and the top of the support platform 131 is provided with an annular fence 133, which provides limiting support for the support tray 121, and the float 132 is fixedly connected to the bottom of the support platform 131. Specifically, the support platform 131 is used to carry the photovoltaic support 12 and the photovoltaic panel 11, and the annular fence 133 provided on the top can effectively limit the movement of the support tray 121, ensuring the stability of the photovoltaic support 12 under the action of waves. The float 132 is fixedly connected to the bottom of the support platform 131, providing sufficient buoyancy to support the entire photovoltaic power generation module 1.

[0043] In this embodiment, the float 132 is a hollow float 132 made of low-density high-strength material. The low-density high-strength material can include but is not limited to composite materials or high-strength plastics, etc., which have low density and high strength, can effectively reduce the weight of the float 132, while ensuring its structural stability in severe sea conditions. Specifically, the design of the hollow float 132 can further reduce the overall weight and improve the buoyancy of the buoyant platform 13, thereby enhancing the adaptability of the photovoltaic power generation platform in deep sea environment.

[0044] In this embodiment, a plurality of photovoltaic power generation modules 1 are arranged in a honeycomb array. This array arrangement can effectively improve the space utilization, enhance the stability of the structure, and exhibit similar mechanical properties to chain mail, and reduce the impact of waves on the photovoltaic power generation module 1.
