[0042] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] like Figure 1 and Figure 2 As shown, the flexible photovoltaic support device 100 of an embodiment of the present invention includes a plurality of support assemblies 200, and the plurality of support assemblies 200 are arranged at intervals along a first direction; the support assembly 200 includes a plurality of columns 1, a support component 2 and a first beam 3, and the plurality of columns 1 are arranged at intervals along a second direction, and the first direction and the second direction are orthogonal.

[0044] The embodiment of the present invention enables multiple columns 1 to be arranged in an array in the first direction and the second direction to provide support for the photovoltaic panel. As shown in the figure, the first direction is usually the length direction of a photovoltaic component, and the second direction is usually the width direction of a photovoltaic component.

[0045] The support component 2 is arranged at the top of the column 1, and the support component 2 includes a support body 21 and a first support member 22. The support body 21 is fixedly connected to the column 1, and the support body 21 has a first connecting portion 23. The first support member 22 is rotatably connected to the support body 21, and there is a first elastic member between the first support member 22 and the support body 21. The first support member 22 has a first top support portion 24.

[0046] The supporting component 2 is fixed to the top of the column 1, and the bottom of the column 1 is connected to the underground pile foundation or fixed to the structure. Through the setting of the first connecting part 23 and the first supporting part 24, the top of each column 1 can be supported at multiple points between the first beam body 3 to provide a more practical and flexible flexible connection method.

[0047] The first support member 22 is rotatably connected to the support body 21, so that the first top support portion 24 is more flexible. When multi-point support is formed between the first top support portion 24 and the first connecting portion 23 and the first beam body 3 in the same support component 2, the first support member 22 can be rotated as the force on the first beam body 3 changes, thereby causing the first beam body 3 to bend flexibly.

[0048] The first beam body 3 is elastic and extends along the second direction. The first connecting portion 23 of one supporting component 2 is rotatably connected to the first beam body 3, and the first connecting portion 23 of the other supporting components 2 is snap-connected to the first beam body 3, and the other supporting components 2 are movable along the second direction relative to the first beam body 3; the first top supporting portion 24 of the first supporting member 22 is supported on the lower part of the first beam body 3, and the first top supporting portion 24 is movable in the second direction relative to the first beam body 3.

[0049] It should be understood that the first beam body 3 is elastic, and can bend and deform to a certain extent after being subjected to force, while also being able to ensure that it has sufficient rigidity, and can be reset and rebound after the force on the first beam body 3 is reduced.

[0050] Multiple first connection parts 23 located in the same support assembly 200 are all connected to the first beam body 3. After the first connection part 23 of one support component 2 is rotatably connected to the first beam body 3, the position between the first beam body 3 and the support component 2 can be relatively stable, and will not be displaced or detached from the support component 2. When the first beam body 3 is constrained, the first connection parts 23 in other support components 2 are engaged with the first beam body 3, and can move in the second direction relative to the first beam body 3, while ensuring that the first connection parts 23 of other support components 2 will not detach from the first beam body 3.

[0051] The first supporting portion 24 of the embodiment of the present invention is used to support the bottom of the first beam 3, so that each supporting component 2 can be supported by the first beam 3 at multiple points, thereby preventing the first beam 3 from being subjected to excessive force locally and causing irreversible deformation.

[0052] The flexible photovoltaic support device 100 of the embodiment of the present invention can improve the adaptability to the environment, be used in different curved and complex environments, reduce site restrictions, obtain better lighting, have strong anti-shading capabilities, and the constructed photovoltaic equipment has a high power density.

[0053] In some embodiments, there are multiple first supporting portions 24 in the first supporting member 22 .

[0054] The number of the first supporting parts 24 in the first supporting member 22 may be multiple, for example, 2, 3 or 5.

[0055] The plurality of first supporting portions 24 may be arranged in an array or around the circumference of the column 1 to enhance the supporting effect with the first beam 3 .

[0056] Further, the multiple first supporting parts 24 located in the same first supporting member 22 are divided into two supporting part groups, the two supporting part groups are arranged at intervals along the first direction, and the multiple supporting parts in each supporting part group are arranged at intervals along the second direction.

[0057] For example, the number of the first top support parts 24 is 4, and each top support part group includes two first top support parts 24. The four first top support parts 24 can be arranged on one first support member 22 at the same time. At this time, the first support member 22 is U-shaped, and two first top support parts 24 are arranged on each side. Alternatively, the four first top support parts 24 can also be arranged on two first support members 22 respectively. The two first support members 22 are arranged independently and are rotatably connected to the support body 21 respectively.

[0058] Optionally, the first support member 22 is V-shaped and has two arms, and the end of each arm forms a first supporting portion 24 .

[0059] Optionally, a support wheel 26 is provided at the first supporting portion 24, which is connected to the first beam body 3 via the support wheel 26, so that the first beam body 3 can roll during relative movement, thereby avoiding damage to components during sliding.

[0060] In some embodiments, the first elastic member is a torsion spring 25 .

[0061] The torsion spring 25 is disposed on the connecting shaft between the first support member 22 and the support body 21 , and is used to provide a resilience force for the first support member 22 .

[0062] In some embodiments, the first elastic member is a spring disposed between the first support member 22 and the support body 21 ; by disposing the spring between the first support member 22 and the support body 21 , a lateral pulling force can be provided to the first support member 22 .

[0063] The provision of the first elastic member can make the fit between the first supporting portion 24 and the first beam body 3 better, and the forces on the multiple first supporting portions 24 on the first support member 22 are more evenly distributed, thereby ensuring better force balance at multiple points on the first beam body 3 and optimizing the flexible deformation of the first beam body 3.

[0064] In some embodiments, the number of columns 1 in the same supporting assembly 200 is at least three.

[0065] The number of columns 1 in each supporting assembly 200 may be 3, 4 or more, which is determined according to the width of the photovoltaic assembly in the second direction and the structural performance of the first beam 3 to ensure that the first beam 3 is stably supported.

[0066] In some embodiments, the column 1 is retractable.

[0067] The column 1 is configured as a retractable structure that can be actively adjusted according to changes in the application environment, thereby resetting the photovoltaic panel to an initial state, thereby improving practicality and flexibility, and having a better application effect in areas with uneven shapes.

[0068] For example, the column 1 includes an inner column and an outer column, which are sleeved together and fixedly connected. When the height of the column 1 needs to be adjusted, the inner column is driven to move and then fixed.

[0069] like Figure 3As shown, in some embodiments, an elastic component is provided between the support body 21 and the first connecting portion 23, the elastic component includes a movable sleeve and a second elastic member 28, the support body 21 has a first groove, the movable sleeve is arranged in the first groove, the second elastic member 28 is arranged between the bottom of the first groove and the movable sleeve, the movable sleeve and the support body 21 are connected by a connecting member, and the movable sleeve moves relative to the support body 21 in the direction in which the second elastic member 28 is compressed.

[0070] It should be understood that the first connecting portion 23 can move relative to the supporting body 21, so that the supporting structure of the first beam 3 and the supporting assembly 200 can be flexible and can have an anti-seismic effect. When the photovoltaic panels are arranged on the top of the solar car, it can have a good anti-seismic effect. When encountering strong winds, elastic components can be used to optimize the force of the photovoltaic components and improve the structural stability.

[0071] The positions of the first connecting portion 23 and the first supporting portion 24 in the same column 1 of the embodiment of the present invention can be relatively adjusted, and the arc of the first beam body 3 after elastic deformation is smoother and the force is more stable.

[0072] In some embodiments, the first beam body 3 includes a beam body 31 and a plurality of connecting plates 32 , wherein the plurality of connecting plates 32 are arranged at intervals along the second direction, wherein one of the connecting plates 32 is provided with a circular hole, and the other connecting plates 32 are provided with strip holes 33 .

[0073] In order to facilitate the connection between components, a connecting plate 32 is arranged on the beam body 31. Without damaging the structural performance of the beam body 31, the connecting plate 32 is used to achieve the connection with the supporting component 2. The structure of the connecting plate 32 can be optimized according to the structure of the supporting component 2 to ensure the structural stability between the two, which greatly reduces the requirements for the processing and manufacturing of the beam body 31.

[0074] The round hole is used for rotationally connecting with one of the first connecting parts 23 , and the strip hole 33 is used for snap-connecting with the first connecting part 23 in the other supporting component 2 .

[0075] The snap-in connection in the embodiment of the present invention can be achieved by setting a rotating shaft on the supporting component 2 as the first connecting part 23, and inserting the first connecting part 23 into the long hole to achieve snap-in connection. Alternatively, a T-shaped guide rail can be set on the connecting plate 32, and a T-shaped slot can be set on the supporting component 2 as the first connecting part 23, and the snap-in connection can be achieved by utilizing the cooperation of the T-shaped guide rail and the T-shaped slot.

[0076] In some embodiments, the flexible photovoltaic support device 100 further includes a second beam body 4 , and the second beam body 4 is disposed between two first beam bodies 3 in two adjacent support assemblies 200 .

[0077] The second beam body 4 and the first beam body 3 form a frame structure, thereby providing an installation support platform for the installation of the photovoltaic panel and facilitating the alignment installation of the photovoltaic panel.

[0078] Optionally, mounting holes are arranged on the first beam body 3 and the second beam body 4;

[0079] Furthermore, the rigidity of the second beam body 4 is greater than the rigidity of the first beam body 3 ; and the distance between two adjacent support assemblies 200 is greater than the distance between two adjacent columns 1 in the same support assembly 200 .

[0080] The span of the second beam 4 is relatively larger than the span of the first beam 3 between two adjacent columns 1, so the rigidity of the second beam 4 needs to be increased to ensure the stability of the structure. At the same time, the flexibility of the first beam 3 can be used alone to support the photovoltaic panels in most scenarios.

[0081] Furthermore, a steel cable 5 is arranged between two adjacent second beam bodies 4 in the second direction.

[0082] Adjacent second beams 4 are connected by steel cables 5 , so as to improve the structural stability of the second beams 4 , make the relative positions of the second beams 4 more stable, and form a stable force-bearing system.
