Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to an energy-consuming structure that effectively alleviates the tearing of photovoltaic module frames. Background Technology

[0002] The frame of a photovoltaic (PV) module is an important component. Its main function is to fix and protect the PV module, ensuring its stability and safety during installation and use. Additionally, the frame can enhance the structural strength of the module's edges, preventing deformation or damage caused by external forces.

[0003] In environments with strong winds or snow accumulation, photovoltaic module frames often need to withstand significant external forces. If the frame strength is insufficient, it is prone to deformation or tearing under these forces. Furthermore, due to diurnal temperature variations or seasonal changes, photovoltaic module frames also experience thermal expansion and contraction. If the coefficient of thermal expansion of the frame material does not match that of other module materials such as glass, it can also easily lead to frame tearing. Utility Model Content

[0004] The purpose of this invention is to provide an energy-consuming structure that effectively alleviates the tearing of photovoltaic module frames, thereby solving the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-consuming structure that effectively alleviates the tearing of photovoltaic module frames, including a support frame. The photovoltaic module is connected to the mounting purlin via an elastic support mechanism. The elastic support mechanism includes a connecting frame, a first rubber pad, a fastening bolt, and a serrated groove. The connecting frame is connected to the mounting purlin via the fastening bolt. A first rubber pad is provided between the fastening bolt and the connecting frame. A serrated groove is provided between the connecting frame and the mounting purlin.

[0006] Furthermore, the top of the mounting purlin is fixedly connected to the bottom of the serrated plate, and a sliding groove is provided inside the mounting purlin, with the serrated plate located on both sides of the top of the sliding groove.

[0007] Furthermore, the interior of both the connecting frame and the first rubber pad is movably connected to the outer wall of the fastening bolt. The bottom of the connecting frame is provided with a serrated groove, and the inner wall of the serrated groove is engaged with the outer wall of the serrated plate. The outer wall of the fastening bolt is movably connected to the inner wall of the sliding groove.

[0008] The elastic support mechanism also includes a gasket and a second rubber pad. The gasket is threaded onto a fastening bolt on the underside of the mounting purlin. The diameter of the gasket is at least twice the width of the sliding groove. The second rubber pad is disposed between the gasket and the mounting purlin.

[0009] Compared with the prior art, the beneficial effects of this utility model are: when the device as a whole is affected by external wind pressure, the setting of the first rubber pad makes the connection between the photovoltaic module and the mounting purlin become elastic support, reducing the impact of wind pressure on the device as a whole, and the elastic support further dissipates energy through deformation, thus alleviating the tearing of the photovoltaic module frame.

[0010] When installing photovoltaic modules, the fastening bolts are placed inside the sliding groove. The photovoltaic modules are moved left and right according to the installation position requirements, while the fastening bolts move inside the sliding groove. At the same time, the connecting bracket moves on top of the serrated plate. The fastening bolts are tightened with tools, which in turn causes the serrated groove to engage with the serrated plate. This facilitates the adjustment of the photovoltaic module's position during installation, making the installation of photovoltaic modules more convenient. Attached Figure Description

[0014] To facilitate understanding of this utility model, the technical solution of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example 1: Please refer to the appendix to this instruction manual. Figure 1-3 This utility model provides an energy-consuming structure that effectively alleviates the tearing of the photovoltaic module frame, including a support frame 1, the top of which is provided with a mounting purlin 301, and the photovoltaic module 4 is adjustablely mounted on the mounting purlin 301 through an elastic support mechanism 5.

[0016] Specifically, a serrated plate 302 is fixedly connected to the top of the mounting purlin 301, and a sliding groove 303 is formed inside the mounting purlin 301 along its length. The serrated plate 302 is located on both sides of the top of the sliding groove 303, providing a structural basis for subsequent engagement and locking.

[0017] The elastic support mechanism 5 is the core component connecting the photovoltaic module 4 and the mounting purlin 301. It includes a connecting frame 501, a first rubber pad 502, a fastening bolt 503, and a serrated groove 504.

[0018] The connecting frame 501 is used to support the frame of the photovoltaic module 4. The bottom of the connecting frame 501 has a serrated groove 504 that matches the serrated plate 302. During installation, the serrated groove 504 at the bottom of the connecting frame 501 engages with the outer wall of the serrated plate 302 at the top of the mounting purlin 301, thereby achieving a firm positioning.

[0019] The fastening bolt 503 passes sequentially through the connecting frame 501 and the first rubber pad 502. The first rubber pad 502 is positioned between the head of the fastening bolt 503 and the connecting frame 501, serving as an elastic buffer. After the shank of the fastening bolt 503 passes through the connecting frame 501 and the first rubber pad 502, its outer wall is movably connected to the inner wall of the sliding groove 303, allowing the entire elastic support mechanism 5 and the photovoltaic module 4 to slide along the length of the mounting purlin 301.

[0020] The elastic support mechanism 5 further includes a washer 505 and a second rubber pad 506. The washer 505 is threadedly connected to the fastening bolt 503 on the lower side of the mounting purlin 301. The diameter of the washer 505 is at least twice the width of the sliding groove 303. The second rubber pad 506 is disposed between the washer 505 and the mounting purlin 301. The washer 505 prevents the fastening bolt 503 from slipping out of the sliding groove 303, and the second rubber pad 506 provides cushioning to dissipate energy and further alleviates tearing of the photovoltaic module frame.

[0021] The working principle and usage process of this utility model are as follows:

[0022] Installation and adjustment process:

[0023] When installing the photovoltaic module 4, first remove the nut and washer from the fastening bolt 503, and insert the shank of the fastening bolt 503 from top to bottom into the sliding groove 303 of the mounting purlin 301. Then, place the elastic support mechanism 5 with the photovoltaic module 4 on the mounting purlin 301, so that the fastening bolt 503 passes through the connecting frame 501 and the first rubber pad 502. At this time, since the fastening bolt 503 is not yet tightened, the serrated groove 504 at the bottom of the connecting frame 501 and the serrated plate 302 are not fully engaged, allowing the entire module to move left and right along the length of the mounting purlin 301. After adjusting the photovoltaic module 4 to the predetermined position according to the installation requirements, tighten the fastening bolt 503 with a tool. During the tightening process, the tension of the fastening bolt 503 will cause the connecting frame 501 to move downward, thereby causing the serrated groove 504 at its bottom to engage tightly with the serrated plate 302 at the top of the mounting purlin 301, achieving reliable locking. This structure facilitates precise adjustment of the position of photovoltaic modules during installation, making the installation process more convenient and efficient.

[0024] Energy dissipation and mitigation of the tearing process:

[0025] When the entire device is subjected to external loads such as strong winds, wind pressure will act on the photovoltaic module 4. This force will be transmitted to the mounting purlin 301 through the connecting frame 501. Because a first rubber pad 502 is set between the connecting frame 501 and the fastening bolt 503, the connection between the photovoltaic module 4 and the mounting purlin 301 is changed from a traditional rigid connection to an elastic support. Under the action of wind pressure, the first rubber pad 502 will undergo elastic deformation, absorbing and dissipating some of the energy brought by the wind load through this small deformation (i.e., deformation energy dissipation). This elastic buffering effect can effectively reduce the stress concentration transmitted to the frame of the photovoltaic module 4, avoid frame overload caused by instantaneous strong winds or continuous vibration, thereby significantly mitigating the risk of tearing of the photovoltaic module frame and improving the stability and durability of the entire photovoltaic system.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
