It will be understood that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the invention. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to Figures 1 and 2, an embodiment of the present invention provides a photovoltaic bracket, which includes a rigging assembly 10, an anchoring assembly 11 and a strut assembly 12;

Both ends of the rigging assembly 10 are respectively fixedly connected to a set of anchoring assemblies 11, so that the rigging assembly 10 is in a tensioned state;

The support rod assembly 12 is connected to the rigging assembly 10 to form a spatial three-dimensional support structure. The support rod assembly 12 is used to support the photovoltaic module 20 installed on the rigging assembly 10 .

Specifically, the photovoltaic bracket in the embodiment of the present invention is a flexible bracket system that can be used in various highly undulating environments such as mountains, deserts, and waters. For example, when used in mountains, photovoltaic modules can be installed at different locations according to changes in mountain slopes. When used in waters, it can automatically adapt to the fluctuations of the water surface.

As shown in FIG. 1 , this photovoltaic bracket includes a rigging assembly 10 , an anchoring assembly 11 and a strut assembly 12 . The rigging assembly 10 may include a plurality of ropes with high-strength bending properties, such as steel wire ropes or cables, cables made of high-strength composite materials, etc. The anchoring component 11 is used to fix the rigging component 10 and maintain a certain distance from the ground to prevent the photovoltaic component 20 from contacting the ground. Both ends of the ropes in the rigging assembly 10 are respectively fixedly connected to a set of anchoring assemblies 11, so that each rope is pulled and suspended in the air. The strut assembly 12 is connected to the rigging assembly 10. When the photovoltaic assembly 20 is connected to the photovoltaic bracket of the embodiment of the present invention, the photovoltaic assembly 20 is installed on the rigging assembly 10, and the bottom of the photovoltaic assembly 20 is supported by the strut assembly 12. .

1 and 2 , each support rod in the pole assembly 12 is connected to the rope in the rigging assembly 10 to form a spatial three-dimensional support structure that is not in the same plane. Therefore, multiple connection points at the connecting portion of the strut assembly 12 and the rigging assembly 10 can form multiple support points.

When the photovoltaic module 20 has a heavy weight or is subject to wind load, multiple non-coplanar support points can reduce the risk of torsion or even overturning of the photovoltaic module 20 and the rigging assembly 10 , helping to ensure that the photovoltaic module maintains normal installation. The tilt angle can maintain high power generation efficiency and reduce the risk of damage to photovoltaic modules.

In addition, stabilizing cables 102 are also arranged below the load-bearing surface. Whether it is the load-bearing cable 101 or the stabilizing cable 102, both ends thereof are fixedly connected to the anchoring assembly 11 to pull the rope and suspend it relative to the ground. Based on the illustration, it is easy to understand that the two load-bearing cables 101 and one stabilizing cable 102 form an approximate triangular pyramid shape. This rigging load-bearing structure can adapt to the fluctuations of the terrain, allowing the photovoltaic modules 20 to be installed in place everywhere, achieving Flexible installation connection.

Optionally, referring to Figures 1 and 2, the strut assembly 12 includes a first strut 121, a second strut 122 and a third strut 123;

Specifically, as shown in FIGS. 1 and 2 , in one implementation, the strut assembly 12 of the embodiment of the present invention may include a first strut 121 , a second strut 122 and a third strut 123 . The three struts can have the same shape and structure, and their lengths can be determined according to the spacing between the connected parts.

Combined with the simplified diagram of Figure 2, any three nodes among the first node A, the second node B, the third node C and the fourth node D are coplanar.

In addition, it should be noted that as the number of struts in the strut assembly 12 increases, other shapes of spatial three-dimensional support structures can also be formed, which will not be described in detail in the embodiment of the present invention.

Combined with the diagram in Figure 2, the spatial three-dimensional support structure formed by the above four nodes can form a triangular ACD between a load-bearing cable 101 and a stabilizing cable 102, and between another load-bearing cable 101 and a stabilizing cable 102, a triangular ACD can be formed. The triangular BCD can form a triangular ABD between the two load-bearing ropes 101. It can be seen that a stable triangular support system can be constructed between any two ropes, which has higher spatial stability and can reduce the cost of the photovoltaic modules 20 and the rigging. There is a risk that the assembly 10 as a whole rotates and twists around the rope circumference. In addition, the fourth node D and the third strut 123 can prevent the photovoltaic module 20 from overturning to the right along the M direction in the figure, and the third node C and the second strut 122 can prevent the photovoltaic module 20 from tipping to the right in the N direction in the figure. Overturned on left side. Therefore, this conical tetrahedron-shaped spatial three-dimensional support structure can improve the anti-overturning performance of the photovoltaic module 20 after it is installed and fixed.

The first included angle β ranges from 30° to 30°. 60°. For example, the second included angle β may be 30°, 35°, 40°, 45°, 50°, 55° or 60°.

According to the figure, the opening at the first included angle α faces the first support rod 121 , that is, faces the photovoltaic module 20 . The larger the first included angle α is, that is, the larger the opening is, the larger the photovoltaic module 20 can be supported. The second included angle β can indicate the degree of inclination of the second strut 122 and the third strut 123 relative to the stabilizing cable 102 at the same time, and can also indicate that when the lengths of the second strut 122 and the third strut 123 remain unchanged, the third The distance between node C and the fourth node D. The larger the second included angle β is, the larger the distance between the third node C and the fourth node D will be, which can avoid load concentration when the distance is close, and also help improve the system stability of the photovoltaic bracket.
