Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation devices, specifically a floating photovoltaic panel installation platform on the water surface. Background Technology

[0002] With the global energy crisis and growing environmental awareness, countries around the world are accelerating the development and utilization of clean and renewable energy. Solar photovoltaic power generation, with its significant advantages such as being clean, safe, and renewable, is being widely promoted and applied.

[0003] Traditional ground-mounted photovoltaic (PV) power generation occupies a large amount of land, hindering the development of the solar PV industry. Against this backdrop, floating PV power plants have emerged. Floating PV power plants utilize supporting buoys to float PV modules on the water surface to generate electricity. They not only do not occupy land resources, but the PV modules covering the water surface can reduce water evaporation, inhibit algae growth, and protect water resources. However, existing floating PV devices and their floating installation platforms have the following problems:

[0004] Floating photovoltaic installation platforms can be divided into two types: fixed connection and flexible connection. Fixed connection installation platforms, such as those described in a floating photovoltaic power generation system with publication number CN105958907B, include multiple photovoltaic power generation units and maintenance channel floats. The multiple photovoltaic power generation units and multiple maintenance channel floats are fixedly connected to each other to form a rectangular structure with multiple rows and columns.

[0005] However, during long-term use, the constant undulation of the water waves causes the platform to undulate repeatedly, resulting in repeated stretching and bending of the connection points between the floats. This can eventually lead to damage to the connection points, undermining the structural stability of the platform and making it unsuitable for long-term use.

[0006] Flexible installation platforms, such as the floating flexible photovoltaic support system and water surface photovoltaic power station disclosed in CN219601565U, include a flexible support body, a float, and anchor blocks. The first side of the flexible support body is used to assemble photovoltaic modules, the float is installed on the second side, and the anchor blocks are connected to the flexible support body via fixing cables. The first and second sides of the flexible support body are opposite each other; in application, the first side of the flexible support body is close to the water surface, and the second side is away from the water surface. This floating flexible photovoltaic support system utilizes the float to support the flexible support body and, in conjunction with the anchor blocks, positions the flexible support body on the water surface. This flexible support method prevents damage to the photovoltaic panel support structure due to repeated wave surging.

[0007] However, the flexible connection method makes it difficult to guarantee the stability of the photovoltaic panel support. Furthermore, due to the flexible connection between the photovoltaic panels, they are susceptible to damage from collisions caused by waves. Typically, a large safety distance is required between the photovoltaic panel components to avoid collisions.

[0008] Furthermore, since the floating installation platform needs to be erected on the water body for a long time and the position of the platform will not move, during the long-term erection process, especially in freshwater bodies such as lakes and reservoirs, aquatic plants such as water hyacinth are very likely to grow in the gaps of the installation platform. These plants and the humus they produce over the years will increase the weight of the installation platform or change the center of gravity of the floating installation platform, affecting the floating stability. Moreover, these aquatic plants attached to the gaps of the installation platform are difficult to clean and easily pollute the water body. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, this invention addresses the technical problem of maximizing space utilization and improving power generation efficiency by closely arranging the various outer shells. Compared to traditional flexible connection installation platforms, this method allows for a larger usable area, enabling the installation of denser photovoltaic panel arrays. Furthermore, the ability of the outer shells to slide and undulate vertically allows for independent floating with the waves, unlike traditional fixed connection installation platforms. This avoids damage to the installation platform caused by wave impacts at fixed connection nodes. The independent up-and-down movement of the outer shells with the waves also causes the adjacent, interlocking comb teeth to scrape against each other. The scraping action between the ring blades cuts the roots and stems of aquatic plants, while the scraping action between the teeth crushes them, effectively inhibiting the growth and climbing of aquatic plants on the installation platform and preventing them from affecting the buoyancy and support stability of the outer shells.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a floating photovoltaic panel installation platform on a water surface, comprising:

[0011] The outer casing has a photovoltaic bracket fixedly connected to its top, and a photovoltaic panel is fixedly connected to the top of the photovoltaic bracket.

[0012] First and second slide bars are respectively provided on the side wall of the outer casing, and each first slide bar and second slide bar is alternately arranged;

[0013] The outer shell is a hexagonal prism, and multiple outer shells are arranged in a hexagonal dense stacking arrangement. Adjacent outer shells are slidably connected to each other by a first slide bar and a second slide bar.

[0014] Furthermore, a comb tooth is fixedly provided on the side wall of each of the outer shells between the first slide bar and the second slide bar, the comb tooth of two adjacent outer shells interlocks and engages with each other, and multiple sets of ring blades are evenly distributed on each of the comb tooth, and file teeth are provided at the adjacent corners of each of the outer shells.

[0015] Furthermore, each of the outer shells is fixedly connected to a partition, each of the outer shells is filled with foam above the partition, and each of the outer shells is fixedly connected to a counterweight below the partition.

[0016] Furthermore, each of the counterweight blocks has multiple annular counterweight rings stacked within it.

[0017] Furthermore, each of the outer shells has multiple drainage grooves evenly distributed on its top, and each drainage groove is interconnected.

[0018] Furthermore, each of the outer shells has three locking blocks evenly distributed and rotatably connected at its top edge, and each of the outer shells has three locking slots at its top edge, with the locking blocks and locking slots being staggered.

[0019] Furthermore, each of the outer shells is fixedly connected to a diaphragm frame at its bottom, and each diaphragm frame is fixedly connected to a diaphragm at its bottom end. Each diaphragm has a through hole at its center, and the diaphragm is made of flexible rubber material.

[0020] Furthermore, multiple shells are selected at intervals among the various shells as anchoring nodes, and the bottom of each shell serving as an anchoring node is fixed to the bottom of the water body by steel cables and anchors.

[0021] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) By closely arranging the various shells, this method allows for a larger usable area of ​​the installation platform compared to the traditional flexible connection installation platform, enabling the installation of a denser photovoltaic array and maximizing the use of space to improve power generation efficiency.

[0023] (2) By allowing each shell to slide and undulate with each other in the vertical direction, compared with the traditional fixed connection installation platform, each shell can float independently with the undulation of the waves, avoiding the problem of damage to the installation platform caused by the impact of waves on the fixed connection nodes.

[0024] (3) By utilizing the ability of each shell to float up and down independently with the waves, the adjacent interlocking comb teeth will scrape against each other. The scraping between the ring blades will cut off the roots and stems of aquatic plants, and the scraping between the filing teeth will crush the aquatic plants. This will effectively inhibit the growth and climbing of aquatic plants at the installation platform, thus affecting the buoyancy and support stability of the shell. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, a floating photovoltaic panel installation platform on the water surface includes a shell 10, which is a hexagonal prism with a hollow interior. Multiple shells 10 are arranged in a hexagonal, densely packed manner to form the installation platform. Each shell 10 has three sets of first sliding bars 13 and three sets of second sliding bars 14 fixedly connected to its outer wall. The first sliding bars 13 and second sliding bars 14 on each shell 10 are evenly staggered. Adjacent shells 10 are slidably connected to each other through the first sliding bars 13 and second sliding bars 14. A photovoltaic bracket 11 is fixedly connected to the top of each shell 10, and a photovoltaic panel 12 is fixedly connected to the top of each photovoltaic bracket 11.

[0037] By setting up a floating shell 10 to form an installation platform, a floating installation platform for photovoltaic panels 12 is provided on the water. By setting the first slide bar 13 and the second slide bar 14, the shells 10 are closely arranged and cannot be separated. This improves the overall structural strength of the platform and allows each shell 10 to float up and down independently. When the water surface surges, each shell 10 can float independently with the waves. Compared with a fixed connection installation platform, this can avoid the problem of damage to the floating body connection due to long-term wave impact.

[0038] Furthermore, the hexagonal prism design of each shell 10, and the dense hexagonal stacking design between each shell 10, make the installation platform structure composed of shells 10 compact, and they can support each other more stably, ensuring the structural stability of the entire platform.

[0039] Meanwhile, each shell 10 is relatively independent, and the number of shells 10 can be easily increased or decreased according to actual needs and water area, thereby adapting to changes in the area and shape of the installation platform to suit different water bodies, and the process of increasing or decreasing is simple and convenient.

[0040] like Figure 5 and Figure 6 As shown, each outer shell 10 is fixedly connected to a partition 19, and each outer shell 10 is filled with foam filling 18 above the partition 19. Each outer shell 10 is fixedly connected to a hemispherical counterweight 20 below the partition 19, and each counterweight 20 is stacked with multiple annular counterweight rings 21.

[0041] By setting up foam filling 18 to provide buoyancy for the outer shell 10, and by using foam filling 18 to ensure that even if water seeps into the outer shell 10 through perforations on the surface of the outer shell 10, the foam filling 18 can still provide stable buoyancy, ensuring the stability of the support for the photovoltaic panel 12. At the same time, by setting up counterweights 20 to lower the overall center of gravity of the outer shell 10, the outer shell 10 can always remain vertical when floating in the water. With the close arrangement of each outer shell 10 supporting each other, the entire platform can be kept stable, reducing the swaying of the outer shell 10 caused by water waves.

[0042] By setting the counterweight ring 21, the counterweight weight can be changed and adjusted more freely, thus adapting to support photovoltaic panels 12 of different weights, and also adapting to deployment in water bodies of different densities, such as fresh water and seawater, expanding the application scenarios.

[0043] like Figure 1 As shown, a small number of shells 10 are selected at intervals in the arranged platform as anchoring nodes. The bottom of the shells 10 selected as anchoring nodes is fixed to the bottom of the water body by steel cables and anchors.

[0044] By selecting anchoring nodes and fixing them to the bottom of the water body, the entire installation platform can be stably set on the water surface, preventing the platform from floating around.

[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a comb bar 15 is fixedly provided on the side wall of each outer shell 10 between the first slide bar 13 and the second slide bar 14. The comb bars 15 between two adjacent outer shells 10 are interlocked and engaged. Multiple sets of ring blades 16 are evenly distributed on each comb bar 15. File teeth 17 are provided at the adjacent corners of each outer shell 10.

[0046] By setting up comb teeth 15 and ring blades 16, the ring blades 16 can cut off the aquatic plants attached to the gaps between the shells 10 by utilizing the movement of each shell 10 with the waves. The sets of file teeth 17 can also file and crush the aquatic plants with each other, preventing the branches of aquatic plants from climbing on the installation platform and affecting its buoyancy and support stability. It can also inhibit the growth of plants on the installation platform, avoiding the problem of plants attached to the installation platform being difficult to clean and polluting the water.

[0047] like Figure 3 and Figure 6 As shown, each outer shell 10 has multiple drainage grooves 22 evenly distributed on its top, and each drainage groove 22 is interconnected.

[0048] By setting up drainage channels 22, it is convenient to drain the part of the installation platform that is exposed above the water surface, thus preventing water from accumulating at the bottom of the photovoltaic bracket 11.

[0049] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, each outer shell 10 is fixedly connected to a diaphragm frame 25 at its bottom, and each diaphragm frame 25 is fixedly connected to a disc-shaped diaphragm 26 at its bottom. Each diaphragm 26 has a through hole 27 at its center and is made of flexible rubber material.

[0050] By setting the diaphragm 26, the outer casing 10 can provide resistance as it floats up and down with the waves, thereby reducing the amplitude of the floating of the outer casing 10 and thus avoiding the problem that the floating amplitude of the outer casing 10 is too large and affects the stability of the outer casing 10 in supporting the photovoltaic panel 12.

[0051] In this embodiment, during installation, the operator first puts the outer shell 10, which serves as the anchoring node, into the water. The outer shell 10, which serves as the anchoring node, is fixed to the bottom of the water by steel cables and anchors. The outer shell 10 floats on the surface of the water, with the top of the outer shell 10 protruding above the water surface. Due to the setting of the counterweight 20, the center of gravity of the outer shell 10 is lower, and the outer shell 10 always remains vertical when floating.

[0052] Subsequently, the operator uses the outer shell 10, which serves as the anchoring node, as a base and connects the remaining outer shells 10 around it. The adjacent outer shells 10 are slidably connected by the first slide bar 13 and the second slide bar 14, so that the outer shells 10 are tightly interlocked in the horizontal direction and slide relatively independently in the vertical direction. Finally, the operator assembles the outer shells 10 into a complete installation platform according to the actual needs and the water area.

[0053] Subsequently, the operators installed photovoltaic brackets 11 and photovoltaic panels 12 on the top of each shell 10, or at intervals on the top of the shell 10. Before deploying the shell 10, the operators calculated the relationship between the water density and the weight of the photovoltaic panels 12 and the buoyancy of the shell 10, and adjusted the number of counterweight rings 21 to change the buoyancy of the shell 10, so that the bottom of the shell 10 could be stably submerged in the water, while the top of the shell 10 could float on the water.

[0054] After installation, due to the close arrangement of the various outer shells 10, this method allows for a larger usable area of ​​the installation platform compared to traditional flexible connection installation platforms, enabling the installation of a denser array of photovoltaic panels 12 and maximizing space utilization to improve power generation efficiency.

[0055] Since the shells 10 can slide and undulate with each other in the vertical direction, compared with the traditional fixed connection installation platform, each shell 10 can float independently with the rise and fall of the waves, avoiding the problem of damage to the installation platform caused by the impact of waves on the fixed connection nodes.

[0056] Furthermore, the closely arranged outer shells 10 support each other, which improves the overall structural strength and stability of the installation platform. When encountering wind and waves, it can more effectively resist the impact of wind and waves, reduce the swaying of the installation platform caused by waves, and improve the support stability of the photovoltaic panel 12.

[0057] When the installation platform is erected on the water for a long time, aquatic plants will inevitably grow in the gaps between the shells 10. Since each shell 10 can float up and down independently with the waves, the adjacent sets of interlocking comb teeth 15 will scrape each other. The scraping action between the ring blades 16 cuts the roots and stems of the aquatic plants, and the scraping action between the filing teeth 17 crushes the aquatic plants. This effectively inhibits the growth and climbing of aquatic plants at the installation platform, thus affecting the buoyancy and support stability of the shells 10.

[0058] Since the outer shell 10 is always undulating with the waves in the water, the aquatic plants can be cut off when they are just sprouting and their stems and leaves are not yet hardened, so that there will be no problem of the aquatic plant stems and leaves being intertwined and filling the gaps and making them difficult to cut.

[0059] As the outer casing 10 floats up and down with the waves, when the outer casing 10 rises, the water around the bottom of the outer casing 10 flows along the bottom contour of the outer casing 10 towards the diaphragm 26. Since the diaphragm 26 is made of flexible rubber, it will become bowl-shaped due to the impact of the water flow, causing the water to flow through the central through hole 27 and generating damping. This will hinder and slow down the rise of the outer casing 10 when it rises. Similarly, when the outer casing 10 falls, the diaphragm 26 can also slow down its fall, thereby limiting the fluctuation of the outer casing 10 and preventing the fluctuation from being too large and affecting the stability of the photovoltaic panel 12.

[0060] Example 2:

[0061] like Figure 2 , Figure 3 , Figure 6 , Figure 6 and Figure 8 As shown, each outer shell 10 has three locking blocks 23 evenly distributed and rotatably connected at its top edge, and each outer shell 10 has three locking slots 24 at its top edge. The locking blocks 23 and locking slots 24 are staggered, and the corresponding locking blocks 23 can be rotated into the corresponding locking slots 24 for connection.

[0062] When this installation platform needs to be erected in water bodies with large waves and poor water stability, such as nearshore environments, the operator can screw the locking block 23 into the corresponding locking groove 24 when assembling the outer shell 10. Then, each locking block 23 and locking groove 24 will interlock with each other, making each outer shell 10 stably locked together, so that the outer shell 10 forms a fixed connection with each other. At this time, the entire installation platform is connected into a complete and stable whole, which can provide more stable support for the photovoltaic panel 12 to adapt to complex and ever-changing usage scenarios.
