Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a floating water photovoltaic device. Background Technology

[0002] With the increasing global demand for clean energy, solar photovoltaic power generation has received widespread attention as a sustainable energy solution. Among the many application scenarios of photovoltaic power plants, floating photovoltaic systems are gradually emerging due to their advantages such as not occupying valuable land resources and the cooling effect of water on photovoltaic panels, which can improve power generation efficiency.

[0003] Early floating photovoltaic devices were mostly fixed pile structures, which required driving piles into the seabed to fix the photovoltaic panel supports. This method was not only difficult and costly to construct, but also caused some damage to the aquatic environment. In addition, it was difficult to implement in some waters with large water level changes or complex underwater geological conditions.

[0004] To address these issues, floating photovoltaic (PV) devices have emerged. These devices mainly consist of support frames, connecting frames, and connectors.

[0005] In existing floating photovoltaic (PV) systems, the design and connection methods of the support frames and connecting frames are crucial to the overall performance of the system. For example, in some related technologies, several support frames are arranged to provide a stable support structure for the PV panels. These support frames must withstand the weight of the PV panels and various external forces that may occur in the complex aquatic environment, such as wind, waves, and currents. However, these technologies may have shortcomings in the stability and flexibility of the connection between the support frames and connecting frames. In some systems facing large waves, the connection structure cannot effectively distribute external forces, leading to excessive pressure on individual support frames, affecting the lifespan and stability of the system.

[0006] Furthermore, existing connection methods have shortcomings in terms of installation and maintenance. Some devices require complex tools and precise alignment during installation, which significantly increases installation time and cost, especially in relatively complex environments such as water operations, where efficiency issues are even more pronounced. Moreover, during maintenance and repair, if a component fails, some existing connection designs may require extensive disassembly of the entire device to replace the damaged part, increasing maintenance costs and downtime, and reducing the reliability and availability of the device.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0043] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0044] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Reference Figures 1-6The first embodiment of this utility model proposes a floating water photovoltaic device, including a support frame 1, which is arranged in a plurality of arrangements to support photovoltaic panels. The support frame 1 is arranged in a plurality of arrangements to support photovoltaic panels. The support frame 1 and the connecting frame 2 are connected in sequence. A first connecting member 3 is disposed on the support frame 1 and a second connecting member 4 is disposed on the connecting frame 2 for connecting with the first connecting member 3.

[0047] In this embodiment, several support frames 1 are arranged to provide a stable support structure for the photovoltaic panel. The support frames 1 can withstand the weight of the photovoltaic panel and various external forces that may occur on water, such as wind, waves, and currents. Connecting frames 2 connect the various support frames 1 together to form an integrated frame structure. This connection method allows the support frames 1 to support each other and share external forces, improving the overall wind and wave resistance of the device. Simultaneously, the connecting frames 2 can also transmit and disperse external forces, evenly distributing localized external forces across the entire device, reducing the pressure on individual support frames 1, thereby extending the device's service life. A first connecting piece 3 is disposed on the support frame 1, and a second connecting piece 4 is disposed on the connecting frame 2; the two are connected to each other. This connection method makes the assembly and disassembly of the support frames 1 and connecting frames 2 very convenient. During installation, only the first connecting piece 3 and the second connecting piece 4 need to be aligned and connected; no complex tools or equipment are required, greatly improving installation efficiency. For example, when installing a photovoltaic device on water, each support frame 1 and connecting frame 2 can be transported to the installation site separately, and then quickly assembled into a whole using the first connector 3 and the second connector 4. During maintenance and repair, the design of the first connector 3 and the second connector 4 also makes it easier to disassemble and replace damaged parts. If a support frame 1 or connecting frame 2 is damaged, the damaged part can be removed for repair or replacement by disassembling the corresponding connector without affecting other parts of the entire device. This convenient maintenance method reduces maintenance costs and improves the reliability and availability of the device.

[0048] Furthermore, the first connector 3 has a spherical groove 301, and the second connector 4 includes a connecting rod 401. The connecting rod 401 is disposed on the connecting frame 2 and has a spherical part 402. The spherical groove 301 is used to accommodate the spherical part 402. The locking member 403 is pressed onto the spherical part 402 and has a through hole 404. The connecting rod 401 passes through the through hole 404, and the locking member 403 is threadedly connected to the first connector 3.

[0049] In this embodiment, the first connecting member 3 is connected to the first connecting member 402 as a whole through the spherical groove 301 and the spherical part 402 under the action of the locking member 403. The key to the connection design of the spherical groove 301 and the spherical part 402 is to enable the connecting frame 2 and the support frame 1 to deflect. In aquatic environments, waves are a continuous and powerful external force. When waves impact the photovoltaic device, this deflectable connection allows the support frame 1 to rotate flexibly within a certain range with the force of the waves. For example, when waves impact from the side, the support frame 1 can disperse and buffer the impact force through deflection with the connecting frame 2, avoiding the impact force of the waves acting directly on the fixed structure of the support frame 1, thereby greatly reducing the damage that waves may cause to the support frame 1. This deflection mechanism is like the shock absorption system of a car, dissipating the external impact energy in a relatively gentle way. It does not rigidly resist the force of the waves, but through clever structural design, the device has a certain amount of torsion under the action of waves, so that the impact force is converted and dispersed in this process, effectively protecting the stability and integrity of the support frame 1 and the entire photovoltaic device. Wave motion on water surfaces is complex and diverse, encompassing varying wavelengths, heights, and directions. The spherically connected photovoltaic (PV) device adapts well to this complexity. Whether facing large waves head-on or smaller waves at an angle, the support frame 1 and connecting frame 2 can deflect accordingly based on the specific wave conditions. This adaptive capability allows the device to maintain relative stability under various wave conditions, reducing the risk of wave damage to the device structure and ensuring the normal power generation function of the photovoltaic panels.

[0050] By adapting to the forces of waves, the spherical connection helps maintain the overall stability of the entire floating photovoltaic system. When part of the support frame 1 deflects due to wave impact, adjacent support frames 1 and connecting frames 2 can adjust themselves to balance this change, ensuring that the entire system does not experience significant swaying or tilting. This overall stability is crucial for the normal operation of the photovoltaic panels, as they need to maintain a relatively stable installation angle and position to ensure power generation efficiency. Frequent swaying of the system not only affects the structural safety of the photovoltaic panels but may also cause the connecting lines between the panels to loosen, affecting the normal operation of the power generation system.

[0051] Furthermore, the first connecting member 3 includes a first fixing member 302 and a second fixing member 303. The first fixing member 302 and the second fixing member 303 form a fixing cavity 304, which is used to fix the support frame 1. The second fixing member 303 has an extension end 305 with a spherical groove 301. A limiting bolt 306 is disposed on the second fixing member 303 for fixing the first fixing member 302 and the second fixing member 303.

[0052] In this embodiment, the first connecting member 3 consists of a first fixing member 302 and a second fixing member 303, forming a fixing cavity 304 for fixing the support frame 1. This design securely clamps the support frame 1 within the fixing cavity 304, effectively preventing swaying or displacement during use. In aquatic environments, facing external forces such as water flow and waves, the fixing cavity 304 provides a stable installation foundation for the support frame 1, ensuring stable support for the photovoltaic panel and improving the overall stability of the photovoltaic device. This ensures that the photovoltaic power generation process is not affected by the instability of the support frame 1. The design of the fixing cavity 304 can accommodate support frames 1 of different specifications within a certain range. By adjusting the relative position or fixing method between the first fixing member 302 and the second fixing member 303, support frames 1 of various sizes can be accommodated, increasing the versatility and flexibility of the device. During the design and installation of the photovoltaic device, there is no need to design different types of first connecting members 3 specifically for support frames 1 of different specifications, reducing production costs and design complexity.

[0053] A limiting bolt 306 is mounted on the second fixing member 303 to secure the first fixing member 302 and the second fixing member 303. This connection method makes the structure of the first connecting member 3 more stable, ensuring that even under the influence of complex aquatic environments such as frequent vibration and water flow impacts during long-term use, the first fixing member 302 and the second fixing member 303 will not loosen or separate. The robust structure of the first connecting member 3 further ensures the reliability of the connection between it and the support frame 1 and the second connecting member 4, maintains the integrity of the entire photovoltaic device structure, and reduces the risk of failure due to loosening of the connecting members. Because the limiting bolt 306 provides a stable connection, it reduces the need for frequent inspection and maintenance due to loosening of the first fixing member 302 and the second fixing member 303. Throughout the operating life of the photovoltaic device, this stable structure reduces maintenance costs and workload, improving the usability and economy of the device.

[0054] The extension end 305 of the second fixing member 303 has a spherical groove 301. This design ensures flexible connection with the second connecting member 4 while increasing buffer space through the structure of the extension end 305. When subjected to external forces such as wave impact, the extension end 305 can alleviate the direct impact of the impact on the connection part to a certain extent, reducing stress concentration and making the connection more stable and reliable. Furthermore, the spherical groove 301 located at the extension end 305 provides suitable accommodation space for the spherical part 402 of the second connecting member 4, ensuring flexible rotation between the connecting frame 2 and the support frame 1 to adapt to the needs of water surface fluctuations and photovoltaic panel angle adjustment. When dealing with external forces such as waves, the structure of the spherical groove 301 at the extension end 305 allows relative deflection between the connecting frame 2 and the support frame 1, effectively dispersing the impact force and protecting the device structure. At the same time, when it is necessary to adjust the photovoltaic panel angle to optimize power generation efficiency, this structure can easily achieve angle adjustment. The two work together to improve the adaptability of the photovoltaic device to complex aquatic environments and its power generation performance.

[0055] Furthermore, the first fixing member 302 has a fixing groove 307, the fixing groove 307 has a first positioning protrusion 308, the first positioning protrusion 308 and the support frame 1 form a positioning groove 309, the second fixing member 303 is slidably disposed in the positioning groove 309, the second fixing member 303 slides into or out of the fixing groove 307 after sliding, the second fixing member 303 has a threaded hole 310, there are several threaded holes 310, after the second fixing member 303 slides, the several threaded holes 310 are respectively located on both sides of the first fixing member 302.

[0056] In this embodiment, a first positioning protrusion 308 is provided in the fixing groove 307 of the first fixing member 302, which cooperates with the support frame 1 to form a positioning groove 309, so that the second fixing member 303 can be assembled with the first fixing member 302 with accurate positioning. This design ensures that the relative positions of each component are highly accurate when installing the first connector 3, reducing subsequent problems caused by installation errors, such as loose connections and uneven structural stress. When installing floating photovoltaic devices on a large scale, this precise positioning mechanism helps to improve the overall installation quality and efficiency. The positioning groove 309 provides a clear installation path and position for the second fixing member 303. During the installation process, the operator can quickly slide the second fixing member 303 into the positioning groove 309 to achieve initial alignment with the first fixing member 302. This greatly shortens the installation time, especially in the relatively complex environment of water operations, reducing the difficulty and workload of installation and improving the convenience of installation.

[0057] When maintenance or inspection of the first connector 3 is required, the second fastener 303 can slide out of the fixing groove 307 along the positioning groove 309. This design facilitates the inspection and maintenance of the internal structure of the first connector 3. For example, if corrosion or damage is found inside the first connector 3, the second fastener 303 can be easily disassembled for processing without the need for complicated disassembly tools and procedures, thus reducing maintenance costs and difficulty.

[0058] Furthermore, it also includes a third connector 5, which is fixed relative to the first fixing member 302, and a buoyancy member 6 is disposed on the third connector 5 to provide buoyancy for the support frame 1.

[0059] In this embodiment, the buoyancy component 6 is fixedly mounted relative to the first fixing component 302 via the third connector 5, providing stable buoyancy for the entire support frame 1. In a water environment, the buoyancy component 6 ensures that the support frame 1 can always remain in a suitable position on the water surface and will not sink due to the weight of the photovoltaic panel or other external forces. For example, under different water level changes or water flow impacts, the buoyancy component 6 can continuously provide sufficient buoyancy to keep the support frame 1 and the photovoltaic panel in a stable floating state, ensuring the normal operation of photovoltaic power generation. The arrangement of the third connector 5 allows the buoyancy component 6 to be evenly distributed around the support frame 1, avoiding buoyancy concentration at a certain point, which could cause the support frame 1 to tilt or become unstable. This evenly distributed buoyancy helps improve the balance and stability of the entire photovoltaic device, reduces stress concentration caused by imbalance, and extends the service life of the device.

[0060] The combination of the third connector 5 and the buoyancy component 6 forms a modular buoyancy system that can be easily connected and disassembled with the support frame 1. During installation, the buoyancy component 6 can be quickly installed simply by fixing the third connector 5 to the first fixing component 302, improving installation efficiency. During maintenance, if the buoyancy component 6 is damaged or needs replacement, it can be easily disassembled for repair or replacement without affecting other parts of the photovoltaic device, reducing maintenance costs and difficulty.

[0061] Furthermore, the first fixing member 302 has a fixing cylinder 311 located below the first fixing member 302. The fixing cylinder 311 is used to accommodate the third connecting member 5. The fixing cylinder 311 has a through hole 312. The third connecting member 5 has a locking cavity 501. After the third connecting member 5 is inserted into the fixing cylinder 311, the locking cavity 501 leads to the through hole 312. It also includes a locking member 7, which passes through the through hole 312 and extends into the locking cavity 501 for connecting the first fixing member 302 and the third connecting member 5.

[0062] In this embodiment, the fixing cylinder 311 of the first fixing member 302 is used to accommodate the third connecting member 5, which provides a clear positioning for the connection between the two. When the third connecting member 5 is inserted into the fixing cylinder 311, the locking cavity 501 corresponds to the through hole 312 of the fixing cylinder 311, so that the locking member 7 can accurately pass through the through hole 312 and extend into the locking cavity 501, realizing the connection between the first fixing member 302 and the third connecting member 5. This precise connection method can effectively avoid loosening or displacement caused by improper connection, ensuring that the connection between the buoyancy member 6 and the support frame 1 is stable and reliable during the operation of the water photovoltaic device. The locking member 7 passes through the through hole 312 and extends into the locking cavity 501, forming a high-strength locking structure. Under various external forces such as water flow impact, wave force, and the weight of the photovoltaic panel itself, this locking structure can withstand large tensile and shear forces, preventing the third connecting member 5 from coming out of the first fixing member 302. For example, in turbulent water or inclement weather conditions, the locking structure can ensure a firm connection between the buoyancy component 6 and the support frame 1, maintaining the stability of the entire device.

[0063] The insert design of the fixing cylinder 311 and the third connector 5, along with the connection method of the locking component 7, makes the installation process simple and quick. When assembling the floating photovoltaic system, operators only need to insert the third connector 5 into the fixing cylinder 311 and then insert the locking component 7 to complete the connection, without the need for complicated alignment or adjustment steps. This simple installation method can improve installation efficiency, especially when installing photovoltaic systems on a large scale, saving significant time and labor costs.

[0064] The fixing sleeve 311 provides a clear installation location for the third connector 5, allowing operators to easily place it in the correct position. Compared to other complex connection methods, this design reduces the possibility of errors during installation, further improving installation accuracy and convenience.

[0065] When maintenance or repair of the buoyancy component 6 or its connecting parts is required, the design of the locking component 7 makes the disassembly process relatively easy. Simply remove the locking component 7 to pull the third connecting component 5 out of the fixing cylinder 311, thus facilitating the inspection, repair, or replacement of the buoyancy component 6 or related connecting parts. This ease of disassembly shortens maintenance time, reduces equipment downtime, and improves the maintainability and availability of the entire photovoltaic system.

[0066] Furthermore, the locking cavity 501 has a first locking part 502, and the locking member 7 has a second locking part 701. The locking member 7 is rotatably disposed in the locking cavity 501. After the locking member 7 rotates, the first locking part 502 engages with the second locking part 701.

[0067] In this embodiment, the locking cavity 501 has a first locking portion 502, and the locking member 7 has a second locking portion 701. When the locking member 7 rotates within the locking cavity 501, the first locking portion 502 engages with the second locking portion 701. This engagement structure creates a strong connection force, effectively preventing the locking member 7 from accidentally loosening or coming off during use. When the floating photovoltaic device faces water flow impacts, wave swaying, and other external forces, the engagement structure ensures that the connection between the first fixing member 302 and the third connecting member 5 remains secure, providing a reliable guarantee for the stability of the entire device. Compared to a simple insertion connection, the engagement structure can better withstand external forces from different directions. When water flow impacts the photovoltaic device from the side, the engaged locking member 7 can disperse and resist lateral tension, preventing the third connecting member 5 from being pulled out of the first fixing member 302. This strong resistance to external forces allows the floating photovoltaic device to operate more stably in complex aquatic environments, reducing safety hazards and equipment damage caused by loose connections.

[0068] The rotating design of the locking member 7 simplifies and speeds up the installation and disassembly process. During installation, simply insert the third connecting member 5 into the fixing cylinder 311 of the first fixing member 302, then insert the locking member 7 into the locking cavity 501 and rotate it a certain angle to engage the first locking part 502 with the second locking part 701. This operation eliminates the need for complex tools and equipment, significantly improving installation efficiency. Similarly, during disassembly, simply rotate the locking member 7 in the opposite direction to separate the first locking part 502 from the second locking part 701, easily removing the third connecting member 5 from the first fixing member 302 for convenient maintenance and replacement. The rotating locking member 7 makes it easier to find the correct engagement position during installation. Operators can judge the rotation angle of the locking member 7 by touch or sight to ensure accurate engagement of the first locking part 502 and the second locking part 701. This ease of positioning and operation makes the installation and disassembly process more intuitive and reliable, reducing installation errors or disassembly difficulties caused by improper operation.

[0069] The snap-fit ​​structure design reduces relative movement and wear at the connection points. During the operation of the floating photovoltaic device, the connection points may experience slight swaying and friction due to water flow and waves. The snap-fit ​​structure ensures a tighter connection between the first fixing member 302 and the third connecting member 5, reducing relative movement and thus minimizing wear at the connection points and extending the device's service life.

[0070] Furthermore, the locking member 7 has a notch 702. After the locking member 7 rotates, a relief groove 703 is formed between the notch 702 and the locking cavity 501, and a relief cavity 704 is formed between the second locking part 701 and the first locking part 502. The relief cavity 704 leads to the relief groove 703. It also includes an insert 8, which is slidably disposed in the relief groove 703. After the insert 8 slides, it slides into or out of the relief cavity 704.

[0071] In this embodiment, a clearance groove 703 is formed between the notch 702 of the locking member 7 and the locking cavity 501, and a clearance cavity 704 is formed between the second locking part 701 and the first locking part 502, with the clearance cavity 704 leading to the clearance groove 703. When the locking member 7 rotates to its position and the first locking part 502 engages with the second locking part 701, the insert 8 can be slidably disposed within the clearance groove 703 and slide into or out of the clearance cavity 704. This design forms a multiple locking mechanism, further enhancing the connection stability between the first fixing member 302 and the third connecting member 5. When the floating photovoltaic device faces complex external forces such as water flow and waves, the multiple locking can effectively prevent the connection from loosening or accidental unlocking, ensuring the safe and stable operation of the device.

[0072] The presence of insert 8 increases the strength and shear resistance of the connection. When the device is subjected to external impact, insert 8 and the snap-fit ​​structure share the external force, dispersing stress and reducing pressure on individual connection points. For example, in the event of strong water flow or strong winds and waves, insert 8 can work in conjunction with locking element 7 and snap-fit ​​to improve the overall resistance of the connection to external forces and protect the photovoltaic device from damage.

[0073] During installation, the locking component 7 is first rotated into place to achieve a snap-fit ​​connection. Then, the insert 8 is slid into the clearance groove 703 and enters the clearance cavity 704. This step-by-step operation is simple and straightforward, requiring no complex tools or professional skills, greatly improving installation efficiency. Installers can quickly and accurately complete the connection operation, ensuring the smooth assembly of the photovoltaic device.

[0074] Furthermore, the locking cavity 501 has a limiting part 503, and the side wall of the notch 702 abuts against the limiting part 503.

[0075] In this embodiment, the limiting portion 503 of the locking cavity 501 abuts against the side wall of the notch 702, providing a clear positional definition for the locking member 7. This design ensures that the locking member 7 can be accurately fixed in a specific position after being rotated into place, preventing unnecessary movement or shaking during use. When the floating photovoltaic device faces water flow impact, wave swaying, and other external forces, the abutment between the limiting portion 503 and the side wall of the notch 702 can effectively resist these external forces, ensuring that the connection between the first fixing member 302 and the third connecting member 5 remains firm and stable at all times.

[0076] When the device is subjected to external impact, the contact between the limiting part 503 and the side wall of the notch 702 can disperse and bear the external force, reducing stress concentration at the connection point. During installation, the limiting part 503 provides a clear positioning reference for the installation of the locking part 7. Operators can quickly and accurately complete the installation operation by rotating the locking part 7 to the position where the side wall of the notch 702 abuts against the limiting part 503. This positioning method makes the installation process simpler and faster, reduces the possibility of installation errors, and improves installation efficiency. The contact between the limiting part 503 and the side wall of the notch 702 makes the operation of the locking part 7 more intuitive and reliable. Operators can easily determine whether the locking part 7 is installed correctly by observing the contact between the side wall of the notch 702 and the limiting part 503. When disassembly or adjustment of the connection is required, the direction and method of unlocking can also be quickly found based on the abutment position, reducing the difficulty of operation and improving work efficiency.

[0077] Furthermore, it also includes a locking bolt 9, which penetrates the locking member 7 and the insert 8.

[0078] In this embodiment, the locking bolt 9 penetrates both the locking member 7 and the insert 8, providing additional locking force to the connection structure. Based on the existing snap-fit ​​structure, clearance groove 703, and insert 8, the addition of the locking bolt 9 forms a double locking mechanism, greatly enhancing the connection stability between the first fixing member 302 and the third connecting member 5. Whether on calm water or in harsh aquatic environments, this double locking effectively prevents the connection from loosening or separating due to external forces. Floating photovoltaic devices may face various powerful external forces, such as strong winds, giant waves, and water currents. The locking bolt 9 can share these external forces with other connection structures, further improving the shear strength and tensile strength of the connection. Even in extreme conditions, it ensures the structural integrity of the photovoltaic device and guarantees normal photovoltaic power generation during normal weather.
