[0002] Solar photovoltaic systems are a popular product for utilizing solar energy in recent years. They use solar panels to directly convert sunlight into electricity, which is crucial for providing clean and renewable energy and reducing dependence on traditional fossil fuels.

[0003] Floating photovoltaic (PV) systems refer to the construction of photovoltaic power stations using idle water surfaces. Floating PV power stations offer numerous advantages, including not occupying land resources, reducing water evaporation, and preventing algae growth, thus possessing broad development prospects. Existing floating PV systems typically consist of a floating PV support structure and several photovoltaic panels installed on the support. The support structure usually comprises several connected floating bodies and steel rod structures mounted on the floating bodies for installing the photovoltaic panels. However, common floating bodies are usually one-piece injection-molded hollow box structures, which suffer from large volume and high transportation costs. Furthermore, common floating bodies are typically fixedly connected in sequence to form a floating platform, with fixed and non-adjustable spacing between the floating bodies, making it impossible to adapt to different aquatic environments.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] like Figures 1 to 5 As shown, a floating photovoltaic system 100 in this embodiment includes a floating photovoltaic support 10 and a plurality of photovoltaic panels 20.

[0019] The floating photovoltaic support 10 includes several floats 1 and a support frame 2.

[0020] See Figure 5 The float 1 includes a box 11 and a cover plate 12; the box 11 is wider at the top and narrower at the bottom and has a hollow interior with an open top surface; the cover plate 12 is closed, adhered and fixed to the open part of the box 11 to seal the interior of the box 11; thus, when the cover plate 12 is not closed and fixed, the boxes 11 can be stacked, which can greatly reduce the space occupied by the float 1 and facilitate storage and transportation.

[0021] The top edge of the float 1 is provided with at least two symmetrically arranged vertically penetrating connecting holes 13. The connecting holes 13 allow the connector 3 to pass through and be locked and fixed to the support frame 2. The support frame 2 can be used to connect the floats 1 into one unit. The connector 3 can be a structure such as screws and nuts.

[0022] Specifically, the top edge of the housing 11 may be provided with at least two symmetrically arranged housing connecting ears 111, and the cover plate 12 is also provided with cover plate connecting ears 121 corresponding to the housing connecting ears 111. The connecting through hole 13 can pass through the cover plate connecting ears 121 and the housing connecting ears 111 vertically.

[0023] like Figures 1 to 3 As shown, the support frame 2 includes several tracks 21 and several support mechanisms 22. Each track 21 is erected and connected to each float 1 in a horizontal and vertical manner, while each support mechanism 22 is installed above the track 21. The top of the support mechanism 22 is used to install and fix the photovoltaic panel 20 to form a complete water photovoltaic system 100.

[0024] Furthermore, the track 21 may include a plurality of longitudinally extending and laterally spaced lower tracks 211 and a plurality of laterally extending and longitudinally spaced upper tracks 212. Both the upper tracks 212 and the lower tracks 211 may be made of track profiles, and the base plate of the track profiles may be densely covered with a plurality of connecting holes 213 along the extension direction of the track 21.

[0025] See Figure 4 Each lower rail 211 can be longitudinally and spaced at the bottom to lock and fix several of the aforementioned floats 1. The two connecting through holes 13 of the float 1 can be locked to different connecting holes 213 located in the longitudinal direction of the lower rail 211 by using the connecting piece 3, thereby realizing the longitudinal adjustment of the position of the float 1.

[0026] Each upper rail 212 can be horizontally and intermittently locked to the top of each lower rail 211. One of the connecting holes 213 of the lower rail 211 can be locked to different connecting holes 213 of the upper rail 212 using a connector 3, thereby enabling horizontal adjustment of the position of the lower rail 211 and the float 1. Of course, one of the connecting holes 213 of the upper rail 212 can also be locked to different connecting holes 213 of the lower rail 211 using a connector 3, thereby enabling vertical adjustment of the position of the upper rail 212.

[0027] Each upper track 212 can be arranged in pairs longitudinally close to each other, and a support top plate 23 can be installed on two adjacent upper tracks 212. The top surface of the support top plate 23 can form a walking and maintenance passage.

[0028] A fixed support mechanism 22 can be installed on the top of the lower track 211. The support mechanism 22 can be installed between longitudinally adjacent support top plates 23. The support mechanism 22 is used to support the photovoltaic panel 20.

[0029] Therefore, the float 1, composed of the aforementioned box 11 and cover plate 12, can be stacked and transported, significantly reducing transportation costs and facilitating handling and movement. Simultaneously, the box 11 and cover plate 12 of the float 1 can be glued together, resulting in high bonding strength and a stable and reliable structure. Furthermore, the float 1 has connecting through holes 13 that can be locked to the connecting holes 213 of the lower rail 211. This rigid connection between the float 1 and the lower rail 211 improves the overall structural stability of the waterborne photovoltaic support 10. Moreover, the position of the float 1 can be adjusted longitudinally, and it can also be adjusted laterally using the connecting holes 213 of the upper rail 212. This allows for convenient adjustment of the spacing between the floats, making it easily adaptable to different terrains and water areas for waterborne photovoltaic installations, thus demonstrating high versatility.

[0030] like Figure 5 As shown, in this embodiment, the box 11 of the float 1 can be roughly in the shape of a rectangular frame that is larger at the top and smaller at the bottom, which can facilitate the stacking of the box 11.

[0031] The open edge of the box 11 may be provided with an outward flange 112. The top surface of the outward flange 112 may be glued and then bonded to the edge of the cover plate 12, which can improve the bonding and fixing effect between the cover plate 12 and the box 11.

[0032] The box connecting ears 111 can be respectively provided in the middle of the front, back, left and right sides of the outer flange 112, and four cover plate connecting ears 121 are provided in the corresponding positions on the cover plate 12; so that after being glued and fixed, the cover plate 12 and the box 11 can be further reinforced and locked by connecting the connector 3 to the lower track 211.

[0033] The box 11 may also be provided with a cross-shaped support plate 14. The support plate 14 abuts against the inner wall of the box 11 in the circumferential direction and at the bottom, and abuts against the bottom of the cover plate 12 at the top, so as to strengthen the structural strength of the box 11 and improve the support performance of the cover plate 12.

[0034] The support plate 14 can be composed of two splicing sub-plates 141. The splicing sub-plates 141 can be stacked for storage and transportation. The splicing sub-plates 141 can have a notch 1411 in the middle. After the two splicing sub-plates 141 are inserted and fixed to each other, the "+" shaped support plate 14 can be formed.

[0035] Meanwhile, the inner peripheral wall of the housing 11 can be provided with four slots 113 for the side insertion and positioning of the cross-shaped support plate 14, which can facilitate the installation of the support plate 14 and improve the connection stability.

[0036] In this embodiment, each slot 113 is surrounded by two spaced peripheral wall ribs 114 that protrude from the inner peripheral wall of the box 11. By setting the peripheral wall ribs 114, a gap can be left between the peripheral walls of the boxes 11 when they are stacked, which facilitates the subsequent separation of the boxes 11.

[0037] Furthermore, the bottom surface inside the box 11 may also have a circular rib 115 located in the middle and a frame-shaped rib 116 located on the outer periphery of the circular rib 115. This can also leave a gap at the bottom between two boxes 11 when they are stacked, which can also facilitate the subsequent separation of the boxes 11.

[0038] Moreover, the aforementioned ribs also serve to strengthen the structural strength of the box 11 itself.

[0039] like Figure 3 As shown, the support mechanism 22 in this embodiment may include a slanted beam 221, a vertical support 222, a support 223, and a plurality of hinge seats 224.

[0040] A set of two longitudinally spaced hinge seats 224 can be installed between the two supporting top plates 23 on each lower track 211. The front hinge seat 224 can be hinged to the front end of the inclined beam 221 that is inclined downward at the front end, and the rear hinge seat 224 can be hinged to the lower end of the vertically arranged vertical support 222. A hinge seat 224 can be installed at the bottom of the rear end of the inclined beam 221, and the rear hinge seat 224 of the inclined beam 221 is hinged to the upper end of the vertical support 222.

[0041] At least two longitudinally spaced support members 223 can be provided between at least two transversely corresponding inclined beam members 221 on the transversely adjacent lower rails 211. Several transversely spaced photovoltaic panels 20 can be locked and fixed on the top of the two support members 223. The photovoltaic panels 20 and the support members 223 can be locked and installed using a clamping assembly (not shown in the figure). The structure of the clamping assembly can refer to the prior art.

[0042] In this embodiment, each lower track 211 has three longitudinally spaced floats 1 at its bottom, and each lower track 211 has six upper tracks 212 and three supporting top plates 23 at its top. The example is given by setting two longitudinally spaced support members 223 on the three inclined beams 221 of the three lower tracks 211 and setting six photovoltaic panels 20 on the two support members 223. Of course, the actual number of installations is not limited to this.

[0043] The inclined beam 221, vertical support 222, and support 223 can all adopt the same track profile as the upper track 212 and lower track 211. The actual length can be cut and selected as needed, thereby adjusting the installation position of each hinge seat 224 as required. The hinge seat 224 can adopt the style of "U" shaped connector 3. By adjusting the position of the hinge seat 224 or the vertical support 222, the installation angle of the inclined beam 221 can also be easily adjusted, thereby achieving the adjustment of the angle of the photovoltaic panel 20.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model.
