A photovoltaic panel bracket is the "skeleton" of a photovoltaic power generation system, and its core functions are to support the photovoltaic panel, ensure the best lighting angle, and resist external loads such as wind and snow; large-scale power stations mostly support the photovoltaic panel through fixed brackets.
[0003] When the photovoltaic panel is installed on the top of the support frame, it is mostly installed by a rigid fixing method. Rigid clamping causes stress concentration during wind vibration or thermal expansion and contraction, resulting in microcracks in the photovoltaic panel. At the same time, for a large-scale installation, the long-span support beam is prone to bending deformation, affecting the flatness of the array. Therefore, the present application proposes a flexible photovoltaic bracket connection structure. Summary of the Invention

[0028] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.
[0029] It should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.
[0030] In the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0031] As Figures 1-5 shown, a flexible photovoltaic support connection structure described in the present utility model includes a flexible pressing connecting frame 330 for directly connecting with the photovoltaic panel 100;
[0032] A horizontally supported aluminum alloy support beam 300 is arranged below the photovoltaic panel 100, and the aluminum alloy support beam 300 is arranged in a "U" shape;
[0033] Two adjacent aluminum alloy support beams 300 are connected by a reinforcing beam 340, and the reinforcing beam 340 is placed inside the aluminum alloy support beam 300.
[0034] An open support structure is formed by the U-shaped aluminum alloy support beams 300, which can be extended in length according to actual needs. Together with the flexible clamping connectors 330, they press the photovoltaic panel 100 frame from above, achieving flexible fixation. Adjacent support beams are laterally connected by reinforcing beams 340 to form an overall frame, improving torsional resistance.
[0035] The "U"-shaped design of the aluminum alloy support beam 300 balances lightweight and load-bearing capacity, reducing material costs. The reinforcement beam 340 enhances lateral stability and prevents the support beam from deforming due to wind load or its own weight. At the same time, it can connect and fix multiple aluminum alloy support beams 300. The flexible clamping method reduces stress concentration on the photovoltaic panel 100 and avoids micro-cracks caused by rigid clamping, thus protecting the photovoltaic panel 100.
[0036] As a technical optimization of the present invention, the reinforcing beam 340 and the aluminum alloy support beam 300 are connected by the first connecting bolt 350.
[0037] The reinforcing beam 340 is fixed to the side wall or bottom of the aluminum alloy support beam 300 by the first connecting bolt 350, forming a detachable rigid connection; the bolt connection simplifies the installation process and facilitates later maintenance or bracket expansion.
[0038] As a technical optimization of the present invention, the flexible pressing connection frame 330 includes a separator 331 for directly pressing against the frame of the photovoltaic panel 100, and the separator 331 is placed between two photovoltaic panels 100.
[0039] Furthermore, the lower surface of the protrusions extending to both sides of the separator 331 is provided with rubber anti-slip protrusions 332.
[0040] The separator 331 is embedded between the frames of adjacent photovoltaic panels 100. It contacts the photovoltaic panels 100 via rubber anti-slip protrusions 332 on its raised lower surface on both sides, using friction to limit displacement and buffer vibration. The rubber anti-slip protrusions 332 reduce direct friction between the metal and the photovoltaic panels 100, preventing frame wear. The separator 331 physically isolates adjacent photovoltaic panels 100, preventing damage caused by thermal expansion and compression.
[0041] As a technical optimization of the present invention, the separator 331 passes through the aluminum alloy support beam 300 through the connecting screw 333, and is fixed by cooperating with the third through nut 334.
[0042] The connecting screw 333 passes through the top and bottom of the transverse aluminum alloy support beam 300, and is locked to the separator 331 by the third through nut 334, forming a two-way fixation. The two-way fastening avoids uneven force distribution at a single point, improves the uniformity of the clamping force distribution, and the through-type design can adapt to different thicknesses of the support beam, making it highly versatile.
[0043] As a technical optimization of the present invention, a support base 200 is provided at the bottom of the photovoltaic panel 100, the support base 200 is fixed to the ground, and a set of adjustment connecting frames 210 for adjusting the angle of the photovoltaic panel 100 is provided at the top of the support base 200.
[0044] One of the adjusting connecting frames 210 is set horizontally, and the other adjusting connecting frame 210 is set at an angle. The two adjusting connecting frames 210 are hinged together, and an inclined rod 220 is fixedly connected to one end of the two adjusting connecting frames 210 that is far apart from each other. The tilt angle of the inclined rod 220 is adjusted by adjusting the installation angle of the two adjusting connecting frames 210.
[0045] The upper surface of the tilting rod 220 is fixedly connected with a limiting connector 230 for fixed connection with the photovoltaic panel 100.
[0046] The support base 200 adjusts the angle of the tilt rod 220 via a pair of hinged adjusting connecting frames 210. The limiting connector 230 fixes the photovoltaic panel 100 to the tilt rod 220, enabling dynamic adjustment of the pitch angle. The angle adjustment mechanism adapts to different latitude lighting conditions, improving power generation efficiency. The hinged structure allows for adaptation to minor terrain undulations, reducing foundation leveling costs. The tilt rod 220 and the limiting connector 230 form a secondary fixation, preventing the photovoltaic panel 100 from slipping in strong winds.
[0047] Connecting the two sets of tilting rods 220 with the reinforcing rod 320 increases the overall stability.
