[0040] In the aforementioned floating photovoltaic system, at least two grooves are provided on the floating body. Correspondingly, the bottom beam in the support assembly is positioned corresponding to and embedded within the grooves, connecting to the floating body. Since the grooves are symmetrically distributed about the center of the floating body along the first direction, under the gravity of the support assembly and the photovoltaic module, the point of application of the pressure exerted by the support assembly on the floating body is located at the center of the floating body along the first direction. Simultaneously, the point of application of the buoyancy force on the floating body is also located at the center of the floating body along the first direction. Therefore, the stress situation of the floating body is simpler, and the connection stability is higher.

[0041] In contrast, when the photovoltaic support is installed at the connection point of the floating body, the pressure exerted by the photovoltaic support on the floating body is applied at both ends of the floating body, while the buoyancy force on the floating body is applied at the middle of the floating body. If the pressure on both ends of the floating body is not equal, the forces on the floating body cannot be balanced, and it is easy for one end to sink and the other end to float, resulting in poor connection stability.

[0060] Example

[0061] Please refer to Figure 1. This embodiment provides a floating photovoltaic system, including a floating body 100, a support assembly 200, and a photovoltaic module 300.

[0062] Referring to Figure 2, specifically, the floating body 100 extends along the first direction X, and at least two grooves 110 are provided on the floating body 100. The grooves 110 extend along the second direction Y, and the at least two grooves 110 are symmetrically distributed about the center of the floating body 100 along the first direction X.

[0063] When the number of grooves 110 is even, every two grooves 110 form a group, and the two grooves 110 in the same group are symmetrical about the center of the floating body 100 along the first direction X. When the number of grooves 110 is odd, one groove 110 is located at the center of the floating body 100 along the first direction X, and the remaining grooves 110 are grouped in pairs, and the two grooves 110 in the same group are symmetrical about the center of the floating body 100 along the first direction X.

[0064] Accordingly, the support assembly 200 includes a bottom beam 210 that extends along the second direction Y. The bottom beam 210 is correspondingly disposed with the groove 110 and is embedded in the corresponding groove 110.

[0065] In addition, the photovoltaic module 300 is mounted on the support module 200.

[0066] Wherein, the first direction X and the second direction Y are both horizontal, and the first direction X is perpendicular to the second direction Y.

[0067] In the aforementioned floating photovoltaic system, since the grooves 110 are symmetrically distributed about the center of the floating body 100 along the first direction X, the pressure exerted by the support assembly 200 on the floating body 100 under the gravity of the support assembly 200 and the photovoltaic module 300 is applied at the center of the floating body 100 along the first direction X. Simultaneously, the buoyancy force acting on the floating body 100 is also applied at the center of the floating body 100 along the first direction X. Therefore, the stress situation of the floating body 100 is simpler, and the connection stability is higher.

[0068] In contrast, when the photovoltaic support is installed at the connection point of the floating body, the pressure exerted by the photovoltaic support on the floating body is applied at both ends of the floating body, while the buoyancy force on the floating body is applied at the middle of the floating body. If the pressure on both ends of the floating body is not equal, the forces on the floating body cannot be balanced, and it is easy for one end to sink and the other end to float, resulting in poor connection stability.

[0069] Referring to Figures 3 and 4, in some embodiments, the floating body includes a main body 130 and a connecting assembly 140. The main body 130 has a groove 110. The connecting assembly 140 includes end connectors 141 and middle connectors 142, which can be connected to any other end connector 141 or middle connector 142. The end connectors 141 include a first connector 1411 and a second connector 1412, which are symmetrically arranged at two ends of the main body 130 along a first direction X. The middle connector 142 includes a third connector 1421 and a fourth connector 1422, which are symmetrically arranged on two sides at the center of the main body 130 along a second direction Y.

[0070] Specifically, in use, the floating body of this embodiment can connect any connector of the main body 130 of the floating body to any connector of the main body 130 of the floating body to form a floating matrix with different structures, adapting to photovoltaic modules 300 with different structures, or adapting to a variety of complex working environments.

[0071] When the first connector 1411 or the second connector 1412 of the float body 130 is connected to the first connector 1411 or the second connector 1412 of other float bodies 130, the multiple float bodies 130 can form a linear floating matrix along the direction from the first connector 1411 to the second connector 1412.

[0072] When the third connector 1421 or the fourth connector 1422 of the float body 130 is connected to the third connector 1421 or the fourth connector 1422 of other float bodies 130, the multiple float bodies 130 can form a linear floating matrix along the direction from the third connector 1421 to the fourth connector 1422.

[0073] Based on the above, the first connector 1411 or the second connector 1412 of the floating body 130 is interconnected with the first connector 1411 or the second connector 1412 of other floating bodies 130. Simultaneously, the third connector 1421 or the fourth connector 1422 of the floating body 130 is also interconnected with the third connector 1421 or the fourth connector 1422 of other floating bodies 130. In this way, multiple floating bodies 130 can form a rectangular floating matrix of any size to support photovoltaic modules 300 of any size, offering flexible use.

[0074] Furthermore, it should be noted that the first connector 1411 or the second connector 1412 of the float body 130 can also be connected to the third connector 1421 or the fourth connector 1422 of other float bodies 130. In this way, the float bodies 130 at the connection point form a "T" shaped structure, so that the floating matrix can be laid at the corner where corners are needed, or so that the floating matrix can adapt to different shapes of working environments.

[0075] In some embodiments, as exemplarily shown in FIG3, the end of the float body 130 is provided with an end face, and the end face is vertically arranged. The end connector 141 is disposed at the center of the end face, and the surface of the end connector 141 is perpendicular to the surface of the end face. Placing the end connector 141 at the center of the end face ensures that when the float body 130 is connected to other float bodies 130 via the end connector 141, the connection is neat, aesthetically pleasing, and reliable. Furthermore, the neatly arranged end face makes this embodiment easier to operate during installation, improving installation efficiency, reducing installation difficulty, and facilitating regular inspection and maintenance.

[0076] In some embodiments, exemplarily as shown in FIG3, both the first connector 1411 and the second connector 1412 are configured as end connecting plates, and the end connecting plates are configured as horizontal plates. Multiple connecting holes are evenly distributed on the end connecting plates. By configuring the first connector 1411 and the second connector 1412 as horizontal plates with connecting holes, it is clear that the first connector 1411, the second connector 1412, and the connecting structure are all standard parts, making the end connector 141 of this embodiment easier to manufacture. Bolts, screws, or other fasteners can be used to connect and fix the components within the connecting holes, and the multiple connecting holes ensure a stable and reliable connection between different float bodies 130.

[0077] In some embodiments, exemplarily as shown in FIG3, the float body 130 is further provided with a vertical surface, and the central connector 142 is disposed at the center of the vertical surface. The surface containing the central connector 142 is perpendicular to the surface containing the vertical surface. Providing a vertical surface on the float body 130 facilitates a neat and aesthetically pleasing connection when the float body 130 is connected to other float bodies 130 via the central connector 142, resulting in a more stable overall floating matrix. In this embodiment, when in use, the float body 130 floats on the sea surface, and the central connector 142 is perpendicular to the vertical surface, facilitating the connection of the float body 130 to other float bodies 130, simplifying the connection process and increasing installation efficiency.

[0078] In some embodiments, exemplary as shown in FIG3, both the third connector 1421 and the fourth connector 1422 are configured as a central connecting plate, and the central connecting plate is configured as a horizontal plate. The third connector 1421 and the fourth connector 1422 are also configured as standard parts, reducing the processing difficulty of the third connector 1421 and the fourth connector 1422 and facilitating the processing and production of this embodiment.

[0079] In some embodiments, exemplarily as shown in FIG3, multiple connecting holes are evenly distributed on the central connecting plate. The presence of connecting holes allows the central connecting plates to be connected using standard components such as bolts and screws, simplifying the connection process, reducing connection difficulty, and improving installation efficiency. The multiple connecting holes ensure the connection strength between the central connecting plates, thereby improving the overall strength of the floating matrix constructed in this embodiment.

[0080] In some embodiments, as exemplarily shown in FIG3, a vertical groove 131 is provided at the center of the vertical surface, and a middle connector 142 is disposed within the vertical groove 131. On the one hand, this makes the overall embodiment lean towards a rectangular column, making the overall appearance more aesthetically pleasing; on the other hand, the middle connector 142 being disposed within the concave vertical groove 131 facilitates a more proper structural fit when the end connectors 141 and the middle connector 142 are connected to each other, improving the structural rationality of this embodiment.

[0081] Understandably, when the middle connector 142 needs to be connected to other middle connectors 142, the lengths of the third connector 1421 and the fourth connector 1422 can be extended to extend beyond the vertical groove 131 for easy connection. Other arbitrary connectors can also be used, such as connecting ropes passing through connecting holes, or connecting plates and bolts, resulting in a flexible and adaptable connection structure.

[0082] In some embodiments, as exemplarily shown in FIG3, the float body 130 is configured as a columnar body with a walking surface 132 on it. The walking surface 132 is horizontally arranged to allow operators to walk. Thus, when multiple float bodies 130 of this embodiment are interconnected to form a floating matrix, they can not only be used to support the photovoltaic module 300 for photovoltaic power generation, but also allow operators to walk on the float bodies 130, thereby diversifying the functions of this embodiment.

[0083] It should be noted that in related technologies, when damage occurs to structures outside the edges of the floating matrix, operators cannot directly access or see the damaged area, making inspection or maintenance relatively cumbersome. In this embodiment, after the floating matrix is ​​constructed, operators can walk on it. This allows operators to inspect and maintain any location within the embodiment, and simultaneously inspect and maintain photovoltaic modules 300 at any location, improving the practicality of this embodiment.

[0084] In some embodiments, for example, as shown in FIG3, the float body 130 is configured as a rectangular column. In this way, the shape of the float body 130 is more regular and beautiful. In actual use, the connection between the float body 130 and other float bodies 130 is more convenient, and the force on the float body 130 is more balanced, thereby improving the rationality of the structure of this embodiment.

[0085] In some embodiments, for example, the float body 130, the connecting component 140, and the groove 110 are all integrally blow-molded, so that the entire embodiment has no moving parts, requiring no assembly during use, and the overall structure is more stable and reliable. In addition, the blow-molded float body 130 can also ensure the sealing of the cavity inside the float body 130, thereby ensuring the buoyancy of this embodiment.

[0086] It should be noted that in this embodiment, the float body 130 can be moved to a suitable position and spliced ​​with other float bodies 130. The installation process is simple and convenient, using common parts such as screws, bolts or fixing pins, which are inserted into the connection holes for connection and fixation.

[0087] Referring to Figure 5, in some embodiments, the support assembly 200 further includes a first support member 220, a column 230, and a second support member 240.

[0088] The first support member 220 and the column 230 are both installed on the bottom beam 210, and the first support member 220 and the column 230 are arranged along the second direction Y, while the second support member 240 is installed at the top of the column 230.

[0089] Accordingly, the photovoltaic module 300 is mounted on the first support 220 and the second support 240.

[0090] Because the second support member 240, located at the top of the column 230, is higher than the first support member 220, the photovoltaic module 300 can be installed and fixed at an angle. Understandably, the angle of inclination of the photovoltaic module 300 is the angle between the line connecting the first support member 220 and the second support member 240 and the horizontal direction. Compared to traditional floating photovoltaic systems, the support assembly 200 in this embodiment eliminates the need for cross braces and part of the column 230, resulting in a simpler structure and easier installation.

[0091] Please refer to Figure 6. In some embodiments, the top of the first support member 220 has a first support surface 2241, which is inclined relative to the second direction Y.

[0092] Understandably, the first support surface 2241 is parallel to the line connecting the first support member 220 and the second support member 240, and also parallel to the photovoltaic module 300. At this time, the top of the first support member 220 is in surface contact with the photovoltaic module 300, which helps to ensure that the photovoltaic module 300 is subjected to uniform force and can more stably install and fix the photovoltaic module 300.

[0093] Please refer to Figure 7. Similarly, the top of the second support member 240 has a second support surface 241, which is coplanar with the first support surface 2241.

[0094] At this time, the top of the second support member 240 is also in surface contact with the photovoltaic module 300, so that the photovoltaic module 300 is evenly stressed and the photovoltaic module 300 is stably installed and fixed.

[0095] Please refer to Figure 6 again. In some embodiments, the first support member 220 is a quadrilateral support structure, which consists of a bottom plate 221, a first side plate 222, a second side plate 223, and a top plate 224.

[0096] The base plate 221 is horizontally positioned and is mounted on the base beam 210.

[0097] The first side plate 222 and the second side plate 223 are both vertically arranged, with the first side plate 222 being lower than the second side plate 223. The first side plate 222 is connected to one end of the base plate 221 along the second direction Y, and the second side plate 223 is connected to the other end of the base plate 221 along the second direction Y, and is located between the first side plate 222 and the column 230.

[0098] One end of the top plate 224 is connected to the first side plate 222, and the other end of the top plate 224 is connected to the second side plate 223, thus tilting relative to the second direction Y. At this time, the top surface of the top plate 224 is the first support surface 2241.

[0099] The first support member 220, which is quadrilateral, has a simple structure, is easy to install, and can stably connect the bottom beam 210 and support the photovoltaic module 300.

[0100] For example, the base plate 221, the first side plate 222, the second side plate 223 and the top plate 224 are integrally formed, and the base plate 221 is bolted to the bottom beam 210.

[0101] Please refer to Figure 7 again. In some embodiments, the second support member 240 is columnar, and the axis of the second support member 240 is parallel to the first support surface 2241. In this case, the top surface of the second support member 240 is the second support surface 241.

[0102] For example, the second support member 240 is cut from U-shaped steel, which is easy to obtain and process.

[0103] Furthermore, the top surface of the column 230 is parallel to the first support surface 2241, and the top surface of the column 230 is attached and fixed to the bottom surface of the second support member 240.

[0104] In other words, the column 230 is directly connected to the second support member 240, which makes the structure simpler and easier to install.

[0105] In contrast, the existing floating photovoltaic system uses a column 230 connected to a cross brace via connectors, which is structurally complex, involves cumbersome installation steps, and is inconvenient.

[0106] Referring to Figure 8, in some embodiments, the bottom end of the column 230 abuts against the bottom beam 210, and the bottom end of the column 230 has a mounting portion 231. The mounting portion 231 extends along the second direction Y and is connected to the bottom beam 210.

[0107] During assembly, the column 230 is directly connected to the bottom beam 210, which makes the structure of the above-mentioned floating photovoltaic system simpler and the installation more convenient.

[0108] In contrast, existing floating photovoltaic systems often have columns 230 connected to the supporting beams below via connectors, resulting in complex structures and cumbersome installation procedures.

[0109] For example, the mounting part 231 is bolted to the bottom beam 210.

[0110] Please refer to Figures 6 and 7 together. In some embodiments, the bracket assembly 200 further includes a pair of clamping members 250, each clamping member 250 including a fixing part 251 and a clamping part 252 connected to each other.

[0111] One of the clamping members 250 has a fixing part 251 connected to the first support member 220, and a clamping part 252 used to clamp the bottom end of the photovoltaic module 300, pressing the bottom end of the photovoltaic module 300 tightly onto the first support member 220. The other clamping member 250 has a fixing part 251 connected to the second support member 240, and a clamping part 252 used to clamp the top end of the photovoltaic module 300, pressing the top end of the photovoltaic module 300 tightly onto the second support member 240. Finally, the photovoltaic module 300 is installed and fixed onto the bracket assembly 200.

[0112] For example, the fixing part 251 is bolted to the first support member 220 and to the second support member 240.

[0113] Furthermore, the clamping member 250 also includes a supporting portion 253, which is used to support the photovoltaic module 300 in a direction parallel to the photovoltaic module 300. In addition, the fixing portion 251 is connected to the clamping portion 252 via the supporting portion 253.

[0114] In use, the supporting parts 253 of the same pair of clamping parts 250 support the photovoltaic module 300 from both sides, limiting the position of the photovoltaic module 300 and enabling the photovoltaic module 300 to be installed and fixed more stably.

[0115] Please refer to Figure 1 again. In some embodiments, the floating floats 100 are arranged in multiple rows. The floating floats 100 in the same row are connected sequentially along the first direction X, and the floating floats 100 in adjacent rows are spaced apart along the second direction Y.

[0116] Meanwhile, the bottom beam 210 extends along the second direction Y and is embedded in the grooves 110 on multiple floating bodies 100, connecting with multiple rows of floating bodies 100. At this time, the bottom beam 210 extending along the second direction Y and the floating bodies 100 connected sequentially along the first direction X together form a crisscrossing mesh structure, making the entire floating photovoltaic system integrated.

[0117] Understandably, the number of floating bodies 100 in each row can be the same or different, and this embodiment does not limit this. In other words, the floating bodies 100 can be flexibly combined so that the total length of each row of floating bodies 100 along the first direction X is different and adapted to the shape of the water area. In this case, the above-mentioned floating photovoltaic system is easier to design and assemble.

[0118] Furthermore, each end of the floating body 100 along the first direction X is provided with a first connecting part 120 (equivalent to the aforementioned end connector 141), and the floating bodies 100 in the same row are connected sequentially through the first connecting parts 120.

[0119] In some embodiments, the photovoltaic modules 300 are arranged in multiple rows. The photovoltaic modules 300 in the same row are arranged sequentially along the first direction X, and two rows of photovoltaic modules 300 are arranged between two adjacent rows of floating bodies 100.

[0120] Along the second direction Y, the buoyancy provided by each row of floating bodies 100 is used to support two rows of photovoltaic modules 300, which can save the number of floating bodies 100 while ensuring sufficient buoyancy, thereby saving costs.

[0121] In contrast, existing floating photovoltaic systems often use a row of floats to support a row of photovoltaic modules 300, which requires more floats and is more expensive.

[0122] In addition, a section of bottom beam 210 located between two adjacent rows of floating bodies 100 simultaneously supports two photovoltaic modules 300, preventing the force exerted by the photovoltaic modules 300 on the bottom beam 210 from concentrating in the middle of the bottom beam 210. The middle of the bottom beam 210 is less prone to sinking, and the force is more balanced.

[0123] In some embodiments, the photovoltaic modules 300 are arranged in multiple rows, and the number of photovoltaic modules 300 in each row is the same as the number of floating bodies 100 in each row.

[0124] For example, along the first direction X, the floating body 100 is provided with two grooves 110 for the two bottom beams 210 to be embedded. The first support member 220 and the second support member 240 on the two bottom beams 210 support the same photovoltaic module 300, so that the photovoltaic module 300 corresponds to the floating body 100.

[0125] Among them, a bottom beam 210 may have not limited to a set of first support members 220, columns 230 and second support members 240, and each set of first support members 220, columns 230 and second support members 240 on the same bottom beam 210 may be arranged along the second direction Y, and may cooperate with each set of first support members 220, columns 230 and second support members 240 on adjacent bottom beams 210 to support different photovoltaic modules 300.

[0126] Please refer to Figures 1 and 9 together. In some embodiments, the above-described floating photovoltaic system further includes a walkway float 400. The walkway float 400 extends along the second direction Y and is connected to one end of the floating float 100 along the first direction X.

[0127] When in use, the walkway float 400 provides a walking passage for operators, making it convenient for them to maintain, inspect, and replace the photovoltaic modules 300.

[0128] For example, the walkway float 400 is disposed at the edge of the entire floating photovoltaic system and connected to the end of each row of floating floats 100.

[0129] Furthermore, the walkway float 400 includes a first float 410 and a second float 420. The first float 410 and the second float 420 are alternately arranged and connected along the second direction Y, and the middle part of the first float 410 along the second direction Y is connected to one end of the floating float 100 along the first direction X.

[0130] Understandably, the first float 410 and the floating float 100 can adopt the same structure and have the same specifications, which is convenient for production and processing. On this basis, the second float 420 adopts non-standard parts, and its length changes with the spacing between the two adjacent rows of floating floats 100, which is also easy to design and assemble.

[0131] In some embodiments, a second connecting portion 411 is provided at the middle of the first float 410 along the second direction Y, and the second connecting portion 411 is connected to one end of the floating float 100 along the first direction X.

[0132] The first float 410 has a third connecting part 412 at both ends along the second direction Y, and the second float 420 has a fourth connecting part 421 at both ends along the second direction Y. The first float 410 and the second float 420 are connected by the third connecting part 412 and the fourth connecting part 421.

[0133] Specifically, the second connecting part 411 is connected to the first connecting part 120.

[0134] In summary, the aforementioned floating photovoltaic system, by providing multiple grooves 110 on the floating body 100 and symmetrically distributing each groove 110 about the center of the floating body 100 along the first direction X, ensures that the pressure applied by the support assembly 200 to the floating body 100 is located at the center of the floating body 100 along the first direction X. Simultaneously, the buoyancy force acting on the floating body 100 also acts at the center of the floating body 100 along the first direction X. Therefore, the stress distribution on the floating body 100 is simpler, and the connection stability is higher. Furthermore, the aforementioned floating photovoltaic system is easy to design and assemble, and uses fewer floating bodies 100, thus saving costs.
