For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0055] refer to Figures 1 to 4 A specific embodiment of a photovoltaic flexible bracket of the present invention is described. The photovoltaic flexible bracket specifically includes a column 100 and a support frame 401, wherein at least two columns 100 are arranged and spaced apart along a first direction, and the first direction can be north-south, east-west or other directions. Along the first direction, the first component cable 201, the second component cable 202 and the first stabilizing cable 301 are connected between two adjacent columns 100. The first component cable 201 and the second component cable 202 form a photovoltaic component bearing base surface for bearing and installing the photovoltaic component 800. The first component cable 201, the second component cable 202 and the first stabilizing cable 301 in this embodiment are preferably flexible steel wire cables with a long service life. The first component cable 201 and the second component cable 202 are preferably arranged in a parallel state and have a pre-tightening force in this embodiment. The first component cable 201 and the second component cable 202 have different heights so that the photovoltaic component bearing base surface has a certain angle relative to the horizontal surface. The first stabilizing cable 301 is arranged below the photovoltaic component bearing base surface and closer to the ground. The support frame 401 has three corner points distributed in a triangle. The support frame 401 is respectively connected to the first component cable 201, the second component cable 202 and the first stabilizing cable 301 through the three corner points.

[0056] In this embodiment, by setting a triangular support frame 401 between the first component cable 201, the second component cable 202 and the first stabilizing cable 301, due to the structural stability of the triangle, the relative position stability between the first component cable 201, the second component cable 202 and the first stabilizing cable 301 can be greatly improved, and the photovoltaic component bearing base surface can be prevented from flipping due to wind force. Some possible variant implementations of this embodiment also include that the first component cable 201 and the second component cable 202 are not arranged in parallel, but are located in a position relationship where the extension directions intersect in the same plane, or are located in a position relationship where two extension directions do not intersect in the same plane. It can be flexibly set according to the specific use scenario, and the distance between the three corner points of the support frame 401 can be flexibly set to adapt to the above different use conditions, all of which have the same technical effect of avoiding flipping. In some other embodiments, the first component cable 201 and the second component cable 202 can be used instead of the plate-like structure as the photovoltaic component bearing base surface, and the support frame 401 can be set between the first stabilizing cable 301 and the photovoltaic bearing base surface, which can also achieve the technical effect of avoiding flipping.

[0057] In this embodiment, the support frame 401 is composed of three rods connected end to end, and a connecting piece 402 is hinged at each of the three corner points to adapt and connect with the first component cable 201, the second component cable 202, and the first stabilizing cable 301. In this part of the embodiment, the rod structure can adopt a common form of square rod or cylindrical rod. The hinged connecting pieces 402 are arranged at the corner points of the support frame 401, which can greatly reduce the difficulty of installing the support frame 401 and the first component cable 201, the second component cable 202, and the first stabilizing cable 301. By adjusting the hinge angle between the connecting piece 402 and the support frame 401, it can be adapted to more usage conditions. As a modified implementation method of this part of the embodiment, the first stabilizing cable 301 can also be provided with two or more cables, and accordingly, the support frame 401 can also form a quadrilateral or polygonal structure through the rods. Alternatively, the support frame 401 can be deformed and set to be a triangular plate, a quadrilateral plate or a polygonal plate instead of a rod structure. Compared with the aforementioned embodiment, it has the technical effect of avoiding flipping, but it will increase the weight of the support frame 401 or increase the processing cost of the support frame 401.

[0058] In some embodiments, the plane formed by the three corner points of the support frame 401 is parallel to the column 100. In this part of the embodiments, since the column 100 is generally set to be vertically installed on the ground and perpendicular to the ground, the triangular plane formed by the support frame 401 is also set to be perpendicular to the ground, which has the technical effect of saving the most processing materials. In some other modified embodiments, the plane formed by the three corner points of the support frame 401 may not be set to be parallel to the column 100, but to have a certain angle with the column 100. In this part of the embodiments, the distance between the corner points should be appropriately increased to simultaneously connect the first component cable 201, the second component cable 202 and the first stabilizing cable 301. Under different operating conditions, the relative angle between the support frame 401 and the column 100 can be flexibly set.

[0059] On the basis of all the above embodiments, the support frame 401 may also be preferably provided with a plurality of support frames 401 and evenly distributed between the two columns 100. The plurality of support frames 401 may greatly increase the relative stability relationship between the first component cable 201, the second component cable 202 and the first stabilizing cable 301. Preferably, the spacing between the corner point connected to the first stabilizing cable 301 and the photovoltaic component bearing base surface is evenly changed so that the first stabilizing cable 301 is arched. In some variant embodiments, the first stabilizing cable 301 may also be set to a straight line. The arched shape has a more stable effect than the straight line structure.

[0060] In some embodiments, a second stabilizing cable 302 is further connected between the two columns 100, and a first tie rod 501 is provided between the second stabilizing cable 302 and the first stabilizing cable 301 so that the second stabilizing cable 302 forms an arch opposite to the opening direction of the first stabilizing cable 301. The arch effect is the same as the effect of the first stabilizing cable 301 being set as an arch, and is also to increase the bearing capacity. The second stabilizing cable 302 is provided in the photovoltaic flexible bracket as a further reinforcement structure, and the first tie rod 501 between the second stabilizing cable 302 and the first stabilizing cable 301 has a pre-tightening force to further improve the structural stability of the first stabilizing cable 301. In some embodiments, the second stabilizing cable 302 near the middle position of the two columns 100 can also be directly connected to the support frame 401 used to connect the first stabilizing cable 301 so that the second stabilizing cable 302 forms an arch structure. Similarly, the second stabilizing cable 302 can also be selected as a linear structure.

[0061] On the basis of all the above embodiments, the photovoltaic flexible bracket involved in the present invention can be preferably arranged in multiple groups side by side along the second direction, and the second direction is preferably set to be perpendicular to the first direction. The multiple groups of the columns 100 located on the same side are connected by the same I-beam 600, which is set at the top of the column 100 and used to connect the first component cable 201, the second component cable 202 and the first stabilizing cable 301, which can provide more installation sites for the above three and the connection is more stable. In this part of the embodiment, the second stabilizing cable 302 is intermittently arranged in the multiple groups of the photovoltaic flexible brackets, and the adjacent two photovoltaic flexible brackets are connected with a second tie rod 502, one end of the second tie rod 502 is connected to the second stabilizing cable 302, and the other end is connected to the first component cable 201 or the second component cable 202. The above structure can ensure that the cost of the second stabilizing cable 302 is greatly reduced under the premise of having a stable connection. In addition, it can be known that the second tie rod 502 is preferably arranged perpendicular to the second stabilizing cable 302, which can minimize the processing cost.

[0062] In some embodiments, a side cable 701 is further included, one end of which is fixed, and the other end is connected to the I-beam 600 to balance the tension on both sides of the I-beam 600. It can be known that the first component cable 201, the second component cable 202, the first stabilizing cable 301, and the second stabilizing cable 302 are all arranged on the same side of the I-beam 600, and the side cable 701 is arranged on the other side of the I-beam 600, which can balance the force on both sides of the I-beam 600. Preferably, a fixing frame 702 is also provided to fix the side cable 701. In the aforementioned embodiment, connecting ear plates 601 are also preferably provided on both sides of the I-beam 600; the first component cable 201, the second component cable 202, the first stabilizing cable 301, and the side cable can all be connected to the I-beam 600 through the connecting ear plates 601, and the second stabilizing cable 302 can also be fixed on the column 100 due to its long distance from the photovoltaic module 800.

[0063] On the other hand, the present invention also provides a photovoltaic system, specifically comprising a plurality of photovoltaic components 800 and a photovoltaic flexible bracket in any of the aforementioned embodiments. The photovoltaic components 800 can be detachably installed on the photovoltaic component bearing base through a connecting structure, and have a good anti-flipping effect.

[0064] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
