[0028] The core of this application is to provide a mounting bracket for a water surface photovoltaic system to improve the reliability of the mounting bracket.

[0029] Another core of the present application is to provide a water surface photovoltaic system having the above-mentioned mounting bracket.

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] Photovoltaic power generation uses photovoltaic panels to receive sunlight and generate electricity through the photoelectric effect. Floating photovoltaics are a key branch of the photovoltaic industry. They offer many advantages over terrestrial photovoltaics, including higher efficiency, reduced water evaporation, and the suppression of algae growth. Floating photovoltaics typically utilize a photovoltaic platform constructed on the water surface.

[0032] Surface photovoltaic platforms can be categorized into two types based on their construction method: pile-driven and floating. Generally, in shallow waters (less than 3 meters), fixed piling and support structures are used, i.e., pile-driven and elevated. In deep waters (3 to 10 meters), floating designs are preferred.

[0033] Floating photovoltaic platforms usually use specially designed support systems to enable them to float stably on the water surface to adapt to changes in the water environment, such as fluctuations and currents, and to ensure the stability and safety of the photovoltaic panels.

[0034] Traditional floating photovoltaic platforms typically consist of mounting brackets and photovoltaic panels. The mounting brackets include floats, support poles, and photovoltaic brackets. The support poles are typically placed parallel to the water surface on two floats, with the photovoltaic panels mounted on the support poles via the brackets. However, because the support poles are low to the water surface, they can easily become submerged when the array's buoyancy is insufficient, leading to corrosion and reduced reliability of the mounting brackets. This poses a significant risk to the platform, compromising its safety and stability.

[0035] Furthermore, photovoltaic racks typically consist of front and rear racks, with the top of the rack housing the photovoltaic panels and the bottom mounted on a support pole or float. This complicates the installation of these racks and reduces installation efficiency on surface photovoltaic platforms. Furthermore, to prevent shadows, a certain amount of space is often left between the front and rear rows of panels, reducing installation capacity.

[0036] For this reason, Figure 1 As shown, the present embodiment discloses a mounting bracket for a water-based photovoltaic system, comprising a float 100 and a support rod 200. By tilting the support rod 200 between the two floats 100 to increase the distance between the support rod 200 and the water surface, the risk of the support rod 200 being submerged in water is effectively reduced, thereby improving the reliability of the mounting bracket. Furthermore, by directly mounting the photovoltaic panel 300 on the support rod 200, the front and rear photovoltaic brackets are eliminated, simplifying the installation process, reducing the installation workload, and improving the installation efficiency of the water-based photovoltaic platform.

[0037] The following will be combined Figures 1 to 3 The mounting bracket for the water surface photovoltaic system disclosed in the embodiment of the present application is specifically explained and illustrated.

[0038] Among them, Figure 1As shown, there are at least two floating bodies 100, and the two ends of the support rod 200 are supported on the two floating bodies 100 respectively and connected and fixed by fasteners such as bolts. At the same time, the distance between one end of the support rod 200 and the floating body 100 is greater than the distance between the other end of the support rod 200 and the floating body 100, so that the support rod 200 is tilted between the two floating bodies 100, thereby increasing the distance between the support rod 200 and the water surface, which can effectively reduce the risk of the support rod 200 being submerged in water and improve the reliability of the installation bracket. At the same time, the photovoltaic panels 300 are directly installed on the support rod 200, eliminating the front and rear photovoltaic brackets. By tilting the support rod 200, the photovoltaic panels 300 are tilted, which can reduce the distance between adjacent photovoltaic panels 300, avoid shadowing, increase the installation capacity, simplify the installation process, reduce the installation volume, improve the installation efficiency of the surface photovoltaic platform, and reduce the unit cost of the surface photovoltaic array. It should be noted that the number of floats 100 can be, but is not limited to, two, and can also be three, four, five, or more. The floats 100 can be connected end to end to form two or more rows of floats 100, allowing for the placement of more poles 200, and thus, the installation of more photovoltaic panels 300 on the poles 200. The floats 100 can also be arranged in parallel, allowing for the placement of multiple poles 200, and the poles 200 can be connected end to end. Adjacent poles 200 can share a single float 100, thereby reducing the number of floats 100 required while installing more photovoltaic panels 300 and lowering costs. Of course, the above two solutions can also be combined to form a surface photovoltaic array, which will not be discussed further herein.

[0039] In some embodiments, as Figure 1 and Figure 3 As shown, the float 100 can be a rectangular parallelepiped structure, and the cross section of the float 100 can be a rectangle, and ensure that the largest area of ​​the surface of the float 100 is in contact with the water surface, that is, the long side of the cross section of the float 100 is downward ( Figure 1 The photovoltaic panel 300 is provided with a larger buoyancy support, thereby better ensuring the stability of the photovoltaic platform on the water surface.

[0040] In some embodiments, as Figure 2As shown, at least one end of the support rod 200 is bent toward the floating body 100, so that the bent end 201 of the support rod 200 is tilted toward the other end. For ease of understanding, the two ends of the support rod 200 are defined as a first end and a second end, respectively. The first end of the support rod 200 can be bent toward the floating body 100 to form the bent end 201, thereby raising the first end of the support rod 200 and tilting the first end of the support rod 200 toward the second end. This increases the distance between the support rod 200 and the water surface, effectively reducing the risk of the support rod 200 being submerged in water and improving the reliability of the mounting bracket. Of course, both ends of the support rod 200 can also be bent toward the side of the float 100 at the same time, and the distance between the first end of the support rod 200 and the float 100 is greater than the distance between the second end of the support rod 200 and the float 100, that is, the bending length of the first end of the support rod 200 is greater than the bending length of the second end of the support rod 200, so that the first end of the support rod 200 is tilted toward the second end, thereby increasing the distance between the support rod 200 and the water surface, which can effectively reduce the risk of the support rod 200 being immersed in water, improve the reliability of the installation bracket, and at the same time, the photovoltaic panel 300 installed on the support rod 200 can be tilted to ensure that the photovoltaic panel 300 has a larger light-receiving surface and improve the power generation efficiency. It should be noted that in the above embodiment, the second end of the support rod 200 can also be bent toward the side of the float 100 to form a bent end 201 to raise the second end of the support rod 200, so that the second end of the support rod 200 is tilted toward the first end, thereby increasing the distance between the support rod 200 and the water surface, which can effectively reduce the risk of the support rod 200 being immersed in water and improve the reliability of the installation bracket.

[0041] In some embodiments, as Figure 2 As shown, the angle between the bent end 201 of the support rod 200 and the support rod 200 is γ, and 90°≤γ<180°, so as to ensure the stability of the support of the bent end 201 of the support rod 200. At the same time, in order to improve the support strength and support stability of the bent end 201 of the support rod 200, as shown in FIG. Figure 3 As shown, a reinforcement member 202 is provided between the bent end 201 of the support rod 200 and the support rod 200. The reinforcement member 202 may be a metal rod. For ease of understanding, the two ends of the reinforcement member 202 are defined as a first end and a second end, respectively. The first end of the reinforcement member 202 may be fixed to one side of the bent end 201 of the support rod 200 by a fastener such as a bolt, and the second end of the reinforcement member 202 may be fixed to the same side of the support rod 200 by a fastener such as a bolt, thereby forming a triangular support system for the bent end 201 of the support rod 200, thereby improving the support strength and support stability of the bent end 201 of the support rod 200.

[0042] In the above embodiment, the two ends of the reinforcement member 202 can also be connected between the bent end 201 of the support rod 200 and the support rod 200 by welding, so as to improve the connection strength between the reinforcement member 202 and the bent end 201 of the support rod 200 and the support rod 200. Of course, the number of reinforcement members 202 can also be two, three, or more, and each reinforcement member 202 can be intersectingly arranged between the bent end 201 of the support rod 200 and the support rod 200, or can be respectively arranged on both sides of the bent end 201 of the support rod 200 and the support rod 200. At the same time, the structure of the reinforcement member 202 can be, but is not limited to, a metal rod, and can also be a metal plate or other structural form, which is not limited herein.

[0043] In order to facilitate the connection and fixation of the bent end 201 of the support rod 200 to the floating body 100, the bent end 201 of the support rod 200 is bent to form a connecting portion 2011, so that the connecting portion 2011 can be connected and fixed to the floating body 100 by fasteners such as bolts, thereby improving the convenience of connecting the bent end 201 of the support rod 200 to the floating body 100.

[0044] In the above embodiment, in order to avoid stress concentration at the bending portion of the support rod 200, an arc-shaped transition connection can be adopted between the bent end 201 of the support rod 200 and the support rod 200. At the same time, an arc-shaped transition connection can also be adopted between the connecting portion 2011 and the bent end 201 of the support rod 200. This can effectively avoid stress concentration at the bending portion of the support rod 200, which may cause the support rod 200 to break, and improve the stability and reliability of the mounting bracket.

[0045] In order to realize the installation and fixation of the photovoltaic panel 300 on the support rod 200, Figures 1 to 3 As shown, a clamping member for fixing the photovoltaic panel 300 is provided on the support rod 200. The clamping member includes a first clamping member 203 and a second clamping member 204. The first clamping member 203 is used to fix the end side of the photovoltaic panel 300, and the second clamping member 204 is used to fix the adjacent side of the photovoltaic panel 300 close to the adjacent photovoltaic panel 300. The end side of the photovoltaic panel 300 refers to the long side of the photovoltaic panel 300 close to the end of the corresponding support rod 200, and the adjacent side of the photovoltaic panel 300 refers to the long side away from the end of the corresponding support rod 200 and close to the adjacent photovoltaic panel 300. When there is only one photovoltaic panel 300, both long sides of the photovoltaic panel 300 are end sides, which can be clamped and fixed by the first clamping member 203 respectively. When there are two or more photovoltaic panels 300, the long side of the photovoltaic panel 300 close to the end of the corresponding support rod 200 can be compressed and fixed by the first clamping member 203, and the long side of the photovoltaic panel 300 away from the end of the corresponding support rod 200 and close to the adjacent photovoltaic panel 300 can be compressed and fixed by the second clamping member 204.

[0046] In some embodiments, as Figure 2As shown, the first pressing member 203 can adopt an L-shaped structure, and one end of the first pressing member 203 is provided with a first pressing portion for pressing the photovoltaic panel 300, and the other end of the first pressing member 203 can be connected and fixed to the support rod 200 by a fastener such as a bolt. Specifically, the first pressing member 203 can be formed by bending a metal plate, and the end connected to the photovoltaic panel 300 can be bent to form the first pressing portion, so that the first pressing member 203 and the photovoltaic panel 300 have a larger contact area, thereby ensuring the stability of the end-side installation of the photovoltaic panel 300. Of course, multiple mounting holes can also be provided along the length direction of the support rod 200, so that the first pressing member 203 can be adaptively adjusted according to the installation position of the photovoltaic panel 300, thereby improving the convenience of installing the first pressing member 203.

[0047] In some embodiments, as Figure 2 As shown, the second pressing member 204 can adopt a U-shaped structure, and the second pressing member 204 includes a first arm and a second arm, the first arm can compress the photovoltaic panel 300, and the second arm is connected to the support rod 200 by a fastener such as a bolt. Among them, the second pressing member 204 can be formed by bending a metal plate so that the second pressing member 204 and the photovoltaic panel 300 have a large contact area, ensuring the stability of the adjacent installation of the photovoltaic panel 300. Of course, the second pressing member 204 can also be fixed to the support rod 200 in advance by welding. When installing the photovoltaic panel 300, it is only necessary to insert the adjacent side of the photovoltaic panel 300 between the first arm and the second arm of the second pressing member 204, and then fix the end side of the photovoltaic panel 300 by the first pressing member 203. It should be noted that when there are three or more photovoltaic panels 300, the photovoltaic panel 300 located in the middle can be inserted between the two second pressing members 204 from the side, thereby achieving rapid assembly of the photovoltaic panel 300.

[0048] In the above embodiment, two adjacent photovoltaic panels 300 can also use a shared second pressing member 204 to achieve the connection and fixation of the adjacent sides of the photovoltaic panels 300. In this case, the second pressing member 204 can adopt a butterfly structure, that is, two U-shaped structures are arranged opposite each other, so that the two adjacent photovoltaic panels 300 share a single second pressing member 204 to achieve the connection and fixation effect of the adjacent sides of the photovoltaic panels 300. This will not be described in detail here. It should be noted that the second pressing member 204 can also adopt a C-shaped structure, an L-shaped structure, etc., which will not be described in detail here.

[0049] An embodiment of the present application also discloses a water surface photovoltaic system, including a photovoltaic panel 300 and a mounting bracket supporting the photovoltaic panel 300. The mounting bracket is the mounting bracket for the water surface photovoltaic system disclosed in the above embodiment, and therefore has all the technical effects of the above-mentioned mounting bracket, which will not be repeated here.

[0050] In the above embodiment, to support the photovoltaic panel 300, two support rods 200 are provided, and the two support rods 200 support the two short sides of the photovoltaic panel 300, respectively, to ensure the stability of the installation of the photovoltaic panel 300. Of course, the number of support rods 200 can also be three, four, or more to install more photovoltaic panels 300. Multiple support rods 200 can also be used to support the same photovoltaic panel 300 to improve the stability of the installation of the photovoltaic panel 300. In addition, the number of photovoltaic panels 300 distributed along the length of the support rods 200 can be one, two, three, or more to increase the installation capacity of the surface photovoltaic system.
