[0036] The core of this invention is to provide a water-surface photovoltaic support system, which improves the versatility of the system. Another objective of this invention is to provide a photovoltaic assembly that includes the aforementioned water-surface photovoltaic support system.

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Please refer to Figure 1 and Figure 2 In one specific embodiment, the water surface photovoltaic support system provided by this utility model includes a floating body component 300, a rod 200 and a photovoltaic support frame 120, wherein the photovoltaic support frame 120 can be used to install photovoltaic panels 110, and the photovoltaic panels 110 and the photovoltaic support frame 120 are assembled to form a photovoltaic module assembly 100.

[0039] Specifically, considering that the rod 200 is used on the water surface, it is preferable that the rod 200 is a corrosion-resistant component. The rod 200 can be made of plastic, but to improve the supporting strength of the rod 200, it is preferable that the rod 200 is made of metal, specifically, it can be made of aluminum, stainless steel, etc.

[0040] The floating body assembly 300 includes multiple floating body bodies 330, which are sequentially connected along a first direction. To improve connection stability, a single photovoltaic panel 110 is supported by at least two photovoltaic support frames 120. Multiple photovoltaic panels 110 can be mounted on the two photovoltaic support frames 120, and the photovoltaic panels 110 mounted on the same photovoltaic support frame 120 are arranged sequentially along a second direction, with the first and second directions perpendicular to each other.

[0041] To improve the power generation efficiency of the photovoltaic panel 110, preferably, the first direction can be east-west, and the second direction can be north-south. When the photovoltaic panel 110 is used in the Northern Hemisphere, the upper surface of the photovoltaic panel 110 faces south. When the photovoltaic panel 110 is used in the Southern Hemisphere, the upper surface of the photovoltaic panel 110 faces north. Of course, during installation, depending on the shape and position of the water surface, the first direction is not limited to east-west, and the second direction is not limited to north-south; that is, the orientation of the first and second directions can be adjusted as needed.

[0042] The rod 200 connects to the adjacent float body 330 on the float assembly 300, and the rod 200 has multiple fastener mounting positions along the first direction. Specifically, the fastener mounting positions can be equally spaced mounting holes, specifically threaded holes, or fastener mounting positions can be snap-fit ​​devices, etc. The photovoltaic support frame 120 is detachably fixed to the fastener mounting positions.

[0043] In one specific embodiment, both ends of the rod 200 extend along a first direction to opposite ends of the float assembly 300. For example, when the float assembly 300 is provided on two float bodies 330, the length of the rod 200 is the sum of the lengths of the two float bodies 330 along the first direction. When the float assembly 300 is provided on three float bodies 330, the length of the rod 200 is the sum of the lengths of the three float bodies 330 along the first direction. By fixing multiple float bodies 330 with the rod 200, the photovoltaic support frame 120 can slide from one float body 330 to another, improving the convenience of adjusting the position of the photovoltaic support frame 120.

[0044] By installing rods 200 on the upper surface of the float body 330, and fixing one rod 200 to multiple float bodies 330, the rigidity of the upper surface of the float body 330 and the connection rigidity between the float bodies 330 can be effectively improved, thus enhancing the operation and maintenance experience. During installation, to improve support stability, the rods 200 can be installed along the second direction at the middle position of the upper surface of the float assembly 300; specifically, the upper surface of the float assembly 300 is symmetrically arranged with the rods 200 as the center line.

[0045] As described above, in the water surface photovoltaic support system provided in the specific embodiments of this application, the floating body 330 of the floating body assembly 300 forms the support function of the water surface photovoltaic support system. By setting up rods 200 connecting adjacent floating body bodies 330 on the floating body assembly 300, and the rods 200 having multiple fastener mounting positions along the first direction, when installing the photovoltaic support frame 120, the position of the photovoltaic support frame 120 can be adjusted according to the specifications of the photovoltaic panel 110, and then connected to the corresponding fastener mounting positions to achieve fixation. That is, by setting up rods 200 in the floating body assembly 300 to form multiple fastener mounting positions, specifically, the installation positions of two photovoltaic support frames 120 for installing the same photovoltaic panel 110 on the rods 200 can be adjusted, thereby adapting to photovoltaic panels 110 of various specifications. Therefore, the versatility of the water surface photovoltaic support system provided in this application is improved.

[0046] like Figure 3As shown, the float body 330 is provided with a mounting groove 310 for accommodating the rod 200. The mounting groove 310 extends along a first direction to opposite ends of the float body 330, and the ends of the mounting grooves 310 of two adjacent float bodies 330 are connected. Specifically, the mounting groove 310 can be on a mounting seat that protrudes upward at the top of the float body 330. To improve support stability, the mounting groove 310 can be formed by a downward inward recess in the float body 330.

[0047] The dimensions of the mounting groove 310 are determined by the dimensions of the rod 200, and this application does not impose specific limitations. Specifically, to avoid interference between the photovoltaic support frame 120 and the floating body 330, it is preferable that the top end of the rod 200 protrudes beyond the floating body 330, that is, the height of the top end of the rod 200 is equal to the height of the top end of the floating body 330, thereby facilitating the installation of the photovoltaic support frame 120 and the rod 200.

[0048] In one specific implementation, such as Figure 3 As shown, the mounting groove 310 is located on the upper surface of the float body 330, and the center of the mounting groove 310 is located on the vertical center plane of the float body 330, which is perpendicular to the horizontal plane. That is, the mounting groove 310 is set at the center of the float body 330, which improves the stability of the water surface photovoltaic support system.

[0049] For ease of installation, preferably, both the mounting groove 310 and the rod 200 are straight structures. Specifically, the mounting groove 310 is a strip-shaped straight groove, and the rod 200 can be a straight rod structure.

[0050] To improve sliding stability, preferably, both ends of the rod 200 and the mounting groove 310 are fixedly connected. Specifically, both ends of each float body 330 are locked with the rod 200 by a first fastener 400. The first fastener 400 can be a threaded fastener or a snap-fit, for example, the first fastener 400 is a combination of a plastic wing nut and a bolt.

[0051] The photovoltaic support frame 120 and the rod 200 are slidably engaged so that when adjusting the spacing of photovoltaic modules installed on different photovoltaic support frames 120, the operator can slide the photovoltaic support frame 120 along the rod 200. When it slides to the preset position, the photovoltaic support frame 120 and the rod 200 are locked in the fastener mounting position by fasteners.

[0052] In another specific implementation, such as Figure 4 As shown, by making the photovoltaic support frame 120 slide with the rod 200, the photovoltaic support frame 120 can be slid directly when adjusting the position, which reduces the labor intensity of the workers. Specifically, the photovoltaic support frame 120 can slide along the first direction.

[0053] During assembly, the photovoltaic support frame 120, on which the photovoltaic panels 110 are mounted, overlaps at both ends with two rods 200. Based on the actual specifications of the photovoltaic panels, the installation spacing between adjacent photovoltaic support frames 120 is adjusted along the length of the first direction. After adjustment, the support frames are then fixed to the two rods 200 using the first fastener 400, thus achieving adjustable installation spacing for the photovoltaic support frames 120.

[0054] like Figure 5 and Figure 6 As shown, in one specific embodiment, in order to allow the photovoltaic support frame 120 to slide along a preset path, preferably, the rod 200 is provided with a groove 210, and the photovoltaic support frame 120 is provided with a protrusion 121 that slides with the groove 210. Further, preferably, the protrusion 121 engages with the groove 210 to prevent the photovoltaic support frame 120 from separating from the rod 200 when the photovoltaic support frame 120 is sliding.

[0055] In specific settings, the slide 210 can be an inverted T-shaped groove, and the protrusion 121 can be an inverted T-shaped slider.

[0056] like Figure 7 As shown, each end of the float body 330 along the first direction is provided with a connecting lug 320. The connecting lugs 320 of two adjacent float bodies 330 can be detachably connected. To improve assembly efficiency, preferably, the connecting lugs 320 are integrally formed with the float body 330. The float bodies 330 are connected to each other by a first fastener 400, and the rod 200 is installed in the mounting groove 310 on the upper surface of the float body 330 by metal fasteners.

[0057] During installation, the two connecting ears 320 are connected by a second fastener 500. The second fastener can be a snap-fit, or the second fastener 500 can include a bolt 520 and a nut 510. The bolt 520 and the nut 510 work together to connect the two adjacent connecting ears 320.

[0058] To improve connection stability, preferably, the float body 330 is provided with connecting ears 320 on all four sides, and two adjacent float bodies 330 are connected by two connecting ears 320.

[0059] In one specific embodiment, the float assembly 300 is provided with at least two rows along the second direction, such as Figure 2 As shown, the two rows of floating bodies 330 are floating body 330A and floating body 330B, respectively. The photovoltaic support frame 120 connects the rods 200 on the two adjacent rows of floating body components 300, and is arranged perpendicularly in the first and second directions. By setting at least two rows of floating body components 300, the number of photovoltaic panels 110 can be increased, and the photovoltaic support frame 120 improves the installation stability by connecting two rods 200.

[0060] As described above, with the water surface photovoltaic support system provided by this application, any row of photovoltaic support frames 120 can slide on the rods 200 on the upper surface of the float body 330, thereby adjusting the installation spacing between the photovoltaic support frames 120. After the installation spacing is adjusted, the photovoltaic support frames 120 are fixed with fasteners, which can then be adapted to photovoltaic panels 110 of various specifications, improving the adaptability of the arrayed photovoltaic panels 110.

[0061] This application provides a photovoltaic assembly including a water-surface photovoltaic support system. The water-surface photovoltaic support system is disposed on the water surface and is used to support the photovoltaic panel 110. The water-surface photovoltaic support system is any of the aforementioned water-surface photovoltaic support systems. The specific structure of the water-surface photovoltaic support system has been described above. This application includes the aforementioned water-surface photovoltaic support system and has the same effects.

[0062] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0063] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention.
