[0042] To facilitate understanding of the photovoltaic bracket provided in this application, its application scenario is first explained. In the prior art, the photovoltaic modules in floating photovoltaics are close to the water surface. Due to the complex water environment, especially when encountering extreme working conditions, the waves have a greater impact on the photovoltaic modules, and the photovoltaic modules are easily damaged.

[0043] To this end, the present application provides a photovoltaic bracket to solve the technical problem in the prior art that photovoltaic components are easily damaged by the impact of waves due to being close to the water surface.

[0044] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and implementation methods can be combined with each other if there is no conflict.

[0045] In the exemplary embodiment of the present application, a photovoltaic bracket is provided. Figures 1 to 4 , Figure 1 is a schematic diagram of a three-dimensional structure of a photovoltaic bracket according to an exemplary embodiment; Figure 2 is a schematic diagram of a top view structure of a photovoltaic bracket according to an exemplary embodiment; Figure 3is a schematic diagram of a three-dimensional structure of a component frame according to an exemplary embodiment; Figure 4 It is a schematic diagram of a three-dimensional structure of a floating body according to an exemplary embodiment.

[0046] like Figure 1 As shown, the photovoltaic support is divided into a three-layer structure, and the three-layer structure from bottom to top are respectively a floating body 1, a supporting component 3 and a component frame 2.

[0047] In this embodiment, the floating body 1 is used as a lower structure and floats on the water surface; the floating body 1 is divided into a middle area and an edge area, and the edge area is surrounded by the periphery of the middle area and connected to the middle area.

[0048] Optionally, the middle area and the edge area of ​​the floating body 1 can be made in one piece.

[0049] Optionally, the floating body 1 is a plate structure with an outer contour in the shape of a regular polygon; for example, the floating body 1 is a regular hexagonal plate structure.

[0050] Optionally, the material of the floating body 1 can be selected from HMWHDPE (high molecular weight high density synthetic material) which is quite strong, and various corresponding chemical additives can be added to make the material of the floating body 1 have good weather resistance and impact resistance.

[0051] The assembly frame 2 is used as a superstructure, which is arranged above the middle area of ​​the floating body 1 and is mainly used to carry the photovoltaic components 8; the photovoltaic components 8 are laid on the side of the assembly frame 2 away from the floating body 1.

[0052] Optionally, the component frame 2 is a truss structure with an outer contour of a regular polygon; for example, the component frame 2 is a regular hexagonal truss structure, and the truss structure can be formed by six square tubes 21 of equal length connected in sequence, and connecting plates 22 are provided at both ends of the square tubes 21. The two connecting plates 22 between adjacent square tubes 21 are butt-jointed and fixedly connected by bolts, so that the six square tubes 21 can be fixed together. The advantage of the above technical solution is that the assembly of the truss structure does not require welding, which is convenient for installation and maintenance.

[0053] Optionally, the component frame 2 can be made of a steel pipe made of hot-dip galvanized aluminum-magnesium.

[0054] The support assembly 3 is used as a middle layer structure, which is connected between the assembly frame 2 and the floating body 1 and is mainly used to support the assembly frame 2 and the photovoltaic assembly 8 thereon above the floating body 1; there are multiple support assemblies 3, and multiple support assemblies 3 are circumferentially arranged between the assembly frame 2 and the floating body 1; moreover, the support assembly 3 has a first connection end and a second connection end, the first connection end is connected to the edge side of the assembly frame 2, and the second connection end is connected to the edge area of ​​the floating body 1, and the width of the first connection end is greater than the width of the second connection end.

[0055] Optionally, a plurality of support assemblies 3 are evenly arranged along the circumferential direction between the assembly frame 2 and the floating body 1 .

[0056] Exemplarily, there are six support assemblies 3, the first connection ends of the six support assemblies 3 are connected one-to-one to the six sides of the regular hexagonal truss structure, and the second connection ends of the six support assemblies 3 are connected one-to-one to the six sides of the regular hexagonal plate structure.

[0057] Optionally, the support component 3 is made of hot-dip galvanized aluminum-magnesium.

[0058] By adopting the above technical scheme, by setting the support assembly 3 between the floating body 1 and the assembly frame 2, the photovoltaic assembly 8 set on the assembly frame 2 can be moved away from the floating body 1, and the floating body 1 floats on the water surface, so that the photovoltaic assembly 8 can be moved away from the water surface, that is, the photovoltaic assembly 8 has a certain height from the water surface, and the height can be used to increase the distance from the wave impact to the photovoltaic assembly 8, so as to reduce the impact force of the wave on the photovoltaic assembly 8; in addition, the assembly frame 2 is arranged above the middle area of ​​the floating body 1, and the support assembly 3 is connected between the edge side of the assembly frame 2 and the edge area of ​​the floating body 1, that is, the support assembly 3 is tilted between the assembly frame 2 and the floating body 1, so that the assembly frame 2 can be more stably installed on the floating body 1, thereby improving the structural stability between the assembly frame 2 and the floating body 1; and the support assembly 3 also adopts a structural design that is wide at the top and narrow at the bottom, so that the support assembly 3 has a triangular structure, which is more conducive to enhancing the overall structural strength of the photovoltaic bracket.

[0059] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the support assembly 3 includes a middle support rod 31 and a side support rod 32; there are two side support rods 32, and the two side support rods 32 are symmetrically arranged about the middle support rod 31; wherein, the distance between the ends of the two side support rods 32 connected to the assembly frame 2 is the width of the first connection end; the distance between the ends of the two side support rods 32 connected to the floating body 1 is the width of the second connection end.

[0060] In this embodiment, the support assembly 3 as a whole is two triangular structures, each of which can be jointly constructed by the middle support rod 31, the side support rod 32, the assembly frame 2 and the floating body 1, and the angle formed between the side support rod 32 and the middle support rod 31 is 30°.

[0061] Optionally, the middle support rod 31 and the side support rod 32 can both be made of hot-dip galvanized aluminum-magnesium steel pipe.

[0062] By adopting the above technical solution, the support component 3 is designed as a support rod structure, which can reduce the weight and the use of steel while ensuring the overall structural strength of the photovoltaic bracket, thereby saving costs; moreover, the support rod structure also allows wind and waves to pass between the component frame 2 and the floating body 1, thereby reducing the impact of wind and waves on the photovoltaic bracket; in addition, arranging the support rods into a triangular structure can enhance the connection stability and wind and wave impact resistance between the component frame 2 and the floating body 1.

[0063] In some exemplary embodiments, Figure 1 and Figure 2 As shown, a buoy 4 is provided on the support assembly 3 .

[0064] In this embodiment, the float 4 includes a cylinder and foam, the cylinder is sleeved on the support assembly 3, and the foam is filled between the cylinder and the support assembly 3. By arranging the float 4 on the support assembly 3, a certain buoyancy can be guaranteed even if the float 1 is damaged, so that the entire photovoltaic support can still float on the water.

[0065] Optionally, the material of the cylinder may be polyethylene, and the material of the foam may be polystyrene. The above technical solution is environmentally friendly and pollution-free.

[0066] Optionally, each supporting assembly 3 is provided with a buoy 4, and the heights of the buoys 4 are consistent, so that the buoys 4 can provide a more stable buoyancy for the photovoltaic support.

[0067] Exemplarily, when the support assembly 3 adopts a support rod structure, three buoys 4 may be provided in each support assembly 3, that is, in the same support assembly 3, a buoy 4 may be respectively provided on a middle support rod 31 and two side support rods 32.

[0068] By adopting the above technical solution, by arranging the buoy 4 on the supporting assembly 3, even in extreme working conditions (for example, when the floating body 1 is immersed in water), the buoy 4 can still provide corresponding buoyancy, which can prevent the photovoltaic assembly 8 from being immersed in water and play a protective role. The photovoltaic bracket adopts a structural mode in which the floating body 1 and the buoy 4 coexist, which can provide sufficient buoyancy for the entire photovoltaic bracket, and at the same time can resist wave loads and reduce the impact of impact.

[0069] In some exemplary embodiments, Figures 1 to 3 As shown, a plurality of steel cables 5 are arranged side by side on a side of the component frame 2 away from the floating body 1 , and the steel cables 5 are used to carry the photovoltaic components 8 .

[0070] In this embodiment, a plurality of pairs of vertical plates 6 are provided on a side of the assembly frame 2 away from the floating body 1 . Through holes for connecting the steel cables 5 are provided on the vertical plates 6 . The steel cables 5 are arranged between a corresponding pair of vertical plates 6 .

[0071] The photovoltaic assembly 8 is fixed on two adjacent steel cables 5, and the heights of the two adjacent steel cables 5 along the first direction are different, so that the photovoltaic assembly 8 is inclined relative to the surface of the assembly frame 2 on the side away from the floating body 1; wherein the first direction is the arrangement direction of the floating body 1 and the assembly frame 2. It can also be understood that there is a height difference between the front and rear steel cables 5 fixing the same row of photovoltaic assemblies 8; preferably, the photovoltaic assembly 8 and the surface of the assembly frame 2 on the side away from the floating body 1 can form an inclination angle of 20°.

[0072] Optionally, the vertical plate 6 is fixed to the component frame 2 by welding.

[0073] Optionally, the steel cable 5 is flexible and made of steel strands.

[0074] The advantages of the solution of using the steel cable 5 to carry the photovoltaic module 8 by adopting the above technical solution are: less steel is used, the overall weight of the photovoltaic bracket can be reduced, and the cost can be greatly saved; in addition, it has the characteristics of large span and flexible installation range. Compared with the method of using the traditional column-type frame to carry the photovoltaic module 8, more photovoltaic modules 8 can be installed in the same area. The advantages of the solution of using the inclined setting of the photovoltaic module 8 are: in rainy and snowy weather, it can prevent rain and snow from accumulating on the surface of the photovoltaic module 8 and affecting the power generation efficiency, and it can achieve self-cleaning, eliminating the need to install a photovoltaic cleaning device.

[0075] In some exemplary embodiments, Figure 1 , Figure 2 and Figure 4 As shown, a plurality of cable guides 7 are provided on the outer periphery of the floating body 1, and the cable guides 7 are used to be connected with mooring cables.

[0076] In this embodiment, a connecting hole is provided on the cable guide 7, and the connecting hole is used to connect with the mooring rope to ensure that the entire photovoltaic support can effectively resist periodic loads such as wind and waves.

[0077] Exemplarily, there are twelve cable guides 7 , and the arrangement of the cable guides 7 is as follows: the floating body 1 is a regular hexagonal plate structure, and two cable guides 7 are respectively arranged on the outer peripheral side of each side of the floating body 1 .

[0078] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.
