Compared with the traditional water power station, the bearing surface 3 of the floating box 2 can be used as a corridor and a hydrophilic platform, so that the occupation of the visitable range of the landscape water area is minimized, and the problem of the reduced visitable range is solved to a certain extent.

[0029] As shown in Figure 1 , the water photovoltaic device comprises at least one single body 1, each single body 1 comprises a floating box 2, a column 6 and a photovoltaic assembly.

[0030] The floating box 2 is in a hexagonal prism shape, the top end face is a bearing surface 3, and the floating boxes 2 of different single bodies 1 can be spliced. The floating box 2 provides buoyancy to make the whole device float on the water surface; serves as a mounting base for other structures; and expands the bearing surface 3 through splicing. The hexagonal prism structure is beneficial to the close splicing of multiple floating boxes 2, forms a stable planar structure, and can be flexibly combined according to actual needs, as shown in Figure 1 , the expanded bearing surface 3 is accumulated to adapt to the construction of water photovoltaic devices of different scales.

[0031] The bottom end of the column 6 is fixed on the bearing surface 3 of the floating box 2, the top end forms a mounting surface, and the inside can be provided with a channel to mount various electronic equipment such as inverters and rectifiers. The column 6 can be coaxially distributed with the floating box 2.

[0032] The column 6 is used for supporting the photovoltaic assembly, so that the photovoltaic panel 7 is at a certain height and is convenient for receiving sunlight; the column 6 provides a support point for the installation and rotation of the photovoltaic panel 7; and the internal channel can be used for wiring and the like. The column 6 enables the photovoltaic assembly to be stably mounted, and the coaxial distribution with the floating box 2 is beneficial to maintaining the balance and stability of the device, and at the same time facilitates the circumferential distribution of the photovoltaic panel 7 around the axis of the column 6, and reasonably utilizes the space.

[0033] The photovoltaic assembly is composed of multiple photovoltaic panels 7 distributed circumferentially around the axis of the column 6. The photovoltaic panel 7 is rotatably mounted on the mounting surface along the radial end of the column 6, and the other end extends outward to the side surface of the column 6. The included angle with the horizontal plane can be adjusted by rotation, and the side surfaces of adjacent photovoltaic panels 7 are oppositely distributed when the adjacent photovoltaic panels 7 are rotated to be coplanar.

[0034] The photovoltaic panel 7 converts solar energy into electrical energy by using the photovoltaic effect; as a shading structure of the bearing surface 3, it provides shading function for the bearing surface 3 below; by adjusting the angle of rotation, the solar energy receiving efficiency can be optimized according to the sunlight angle at different times and seasons. The photovoltaic module realizes the production of clean energy and provides power support for the water-based facility; the photovoltaic panel 7 is not only beautiful but also can effectively shield the bearing surface 3, providing good shading effect, while the rotation function improves the solar energy utilization efficiency and increases the functionality and practicality of the device.

[0035] As shown in Figure 1 The column 6 is in the shape of a hexagonal prism, and the column 6 is coaxially distributed with the floating box 2. In the manufacturing process, the column 6 is processed into a hexagonal prism, and the axis of the column 6 is ensured to coincide with the axis of the floating box 2 during installation. In terms of structure, the hexagonal column 6 is coaxially distributed with the floating box 2, making the force on the device more uniform in all directions.

The stable structure ensures that the device can operate reliably and stably in complex water environments for a long time, reducing the cost of failure and maintenance due to unstable structure.

[0036] The bearing surface 3 is provided with a bearing platform 4 around the column 6, and the bearing platform 4 is installed with a seat. On the bearing surface 3 of the floating box 2, the bearing platform 4 structure is poured or installed around the column 6, and then the seat is fixedly installed on the bearing platform 4.

[0037] The bearing platform 4 serves as the installation basis of the seat and plays a role in stable support. The seat provides a place for tourists to rest and enjoy, meeting the needs of tourists to play in the water in the landscape water area. At the same time, the setting of the bearing platform 4 and the seat also enriches the functions of the device, making it change from a simple power generation facility to a water landscape facility with leisure functions.

[0038] By setting the bearing platform 4 and the seat thereon, the attractiveness of the device to tourists is enhanced, and the tourism value of the landscape water area is improved. Tourists can rest on the device, get close to the water surface, and experience a unique water experience. This increases the tourists' stay time in the landscape water area, bringing more possibilities for the development and utilization of the landscape water area.

[0039] The outer edge of the bearing surface 3 of the floating box 2 is connected with an expansion plate 5, the expansion plate 5 extends radially outward along the floating box 2, the top surface of the expansion plate 5 is flush with the bearing surface 3, and the different monomers 1 are connected through the expansion plate 5. Specifically, the expansion plate 5 is installed at the outer edge of the bearing surface 3 of the floating box 2 by welding, bolt connection, or other methods, ensuring that the top surface of the expansion plate 5 is in the same plane as the bearing surface 3. Different monomers 1 are connected by using the pre-set connection structure (such as a clamping groove, a bolt hole, etc.) on the expansion plate 5.

[0040] The expansion plate 5 increases the bearing surface 3 of the individual 1 of the floating box 2, enabling the device to carry more equipment or tourists. At the same time, as a connecting component between the individuals 1, the expansion plate 5 provides a more stable connection than directly splicing through the floating box 2, enhancing the structural strength of the entire device. In addition, the arrangement of the expansion plate 5 can also optimize the layout of the device on the water surface, enabling it to better adapt to landscape water areas of different shapes and sizes, improving the combination flexibility and carrying capacity of the device.

[0041] By flexibly connecting the expansion plate 5, multiple individuals 1 can be combined into different sizes and shapes of water photovoltaic facilities according to actual needs, such as continuous linear arrangement, or splicing through three individuals 1 to form a larger platform structure, meeting diverse application scenarios. The stable connection structure ensures the stability of the device under complex water flow and wind wave conditions, ensuring the normal operation of power generation and other functions.

[0042] There are multiple individuals 1, the outer edge of the expansion plate 5 is hexagonal, and the different individuals 1 are connected through the variable positions of the hexagon. According to actual needs, the number of individuals 1 is determined, the outer edge of the expansion plate 5 is designed into a hexagon, and different connection points are arranged on each side of the hexagon. During assembly, by selecting different connection points, the variable position connection between different individuals 1 is realized.

[0043] In addition, when manufacturing the floating box 2, the top bearing surface 3 is processed into a regular hexagonal shape, and the variable position connection method improves the flexibility of the device, enabling flexible adjustment of the connection position and angle of the individual 1 according to the shape and space limitations of the landscape water area, maximizing the use of water space and reducing the occupation of the visitable area. Optimizes the spatial adaptability and layout rationality of the device in the landscape water area. According to the characteristics of different landscape water areas, a variety of layout forms can be constructed, enabling the device to better integrate into the surrounding environment and enhancing the overall aesthetic of the landscape. At the same time, reasonable layout also helps to improve the power generation efficiency and use function of the device, providing a better experience for tourists.

[0044] As shown in Figure 1 The photovoltaic panels 7 are triangular, and when all the photovoltaic panels 7 connected to the same column 6 are coplanar, they form a hexagonal plate shape. The photovoltaic panels 7 are made into triangular shape and are installed around the column 6 axis by rotating seat. When all the photovoltaic panels 7 are rotated to be coplanar, their edges are spliced with each other to form a hexagonal plate shape.

[0045] The triangular photovoltaic panels 7 can make more efficient use of space, increase the number of photovoltaic panels 7, and thus increase the solar energy receiving area and improve the power generation efficiency. When the photovoltaic panels 7 are coplanar and form a hexagonal panel, not only can it provide comprehensive sunshade effect for the underlying bearing surface 3, but also can match the appearance with the hexagonal structure of the entire device, enhancing the aesthetics of the device.

[0046] The floating box 2 is connected with a mooring assembly for mooring the floating box 2 on the water surface; by installing mooring connectors (such as mooring rings, mooring piles, etc.) on the floating box 2, the floating box 2 is connected with anchors on the water bottom or mooring facilities on the shore through cables, anchor chains and other mooring rigging.

[0047] The main function of the mooring assembly is to fix the floating box 2 at a predetermined position to prevent the device from drifting under the action of external forces such as water flow, wind and waves. It ensures that the device can stably stay in the designated water area, ensures that the photovoltaic assembly always aligns with the best light direction, and improves the power generation efficiency. At the same time, the stable position also provides safety for other activities (such as tourists playing, equipment maintenance, etc.) on the device.

[0048] The bearing surface 3 of the regular hexagon perfectly matches the structure of the floating box 2 and the column 6 of the hexagonal prism, which can evenly distribute the load on the device. When placing equipment or having tourists on the bearing surface 3, the regular hexagonal shape can evenly transmit the weight to the floating box 2 and the entire device structure, avoiding local overloading and causing structural damage.

[0049] Effect achieved: The bearing capacity and structural stability of the device are enhanced. Reasonable load distribution enables the device to bear more weight, carry more equipment and tourists, and meet diverse functional requirements. At the same time, the stable structure also prolongs the service life of the device, reduces maintenance costs, and improves the reliability and economy of the device.

[0050] During the manufacturing process of the column 6, an internal passage is reserved, and a rotating seat is installed on the mounting surface at the top end of the column 6. One end of the photovoltaic panel 7 is connected to the rotating seat through a pin shaft, hinge or other connector, realizing rotating connection.

[0051] The internal passage of the column 6 can be used to arrange cables, control lines and other lines, avoiding exposure of the lines and reducing the influence of external environmental factors (such as water, wind, ultraviolet rays, etc.) on the lines, improving the safety and service life of the lines. The rotating seat provides a rotating support point for the photovoltaic panel 7, enabling the photovoltaic panel 7 to adjust the angle according to the light angle and actual needs, improving the efficiency of solar energy receiving, and also providing the possibility for realizing other functions (such as adjusting the position of the photovoltaic panel 7 to create activity space for tourists).

[0052] The rotating seat can be driven by a driving motor through a transmission mechanism such as a gear reduction box, and the photovoltaic panel 7 can change the inclination angle by swinging under the driving of the driving motor. The photovoltaic panel 7 is provided with a support, and the photovoltaic panel 7 is connected to the rotating seat through the support. The support is installed on the photovoltaic panel 7, and bears the main structure of the photovoltaic panel 7, and is connected to the rotating seat through appropriate connecting pieces (such as bolts, pins, etc.).

[0053] The support plays a role of connecting and supporting the photovoltaic panel 7, and enhances the stability of the connection between the photovoltaic panel 7 and the rotating seat. During the rotation of the photovoltaic panel 7, especially when subjected to external forces such as wind, the support can prevent the connection between the photovoltaic panel 7 and the rotating seat from loosening, ensure the stable rotation of the photovoltaic panel 7, and ensure that the photovoltaic panel 7 can accurately adjust the angle according to the design requirements.

[0054] It can be understood that various sensors such as temperature sensors, current and voltage sensors, water level sensors, and weather sensors of the photovoltaic panel 7 can also be installed in the channel of the column 6 to monitor the operating state of the monomer 1. The electric energy generated by the photovoltaic panel 7 can be connected to the power grid through the cable laid in the water.

[0055] The floating box 2 can be made of high-density polyethylene (HDPE) and other lightweight and corrosion-resistant materials, and has good buoyancy and stability. The floating box 2 can be connected to the column 6 through pre-buried bolts and other connecting pieces to fix the position of the column 6, form a stable floating platform, and ensure that the photovoltaic assembly maintains a stable state on the water surface.
