Description

Lightweight photovoltaic module composite frame Technical Field

[0001] This utility model relates to the field of photovoltaic module composite frames, and in particular to a lightweight photovoltaic module composite frame. Background Technology

[0002] Against the backdrop of a continuously rising global demand for clean energy, photovoltaic (PV) power generation has become a key development direction in the energy sector due to its sustainability and environmental friendliness. As the core element of a PV power generation system, the performance and quality of PV modules directly determine the power generation efficiency and lifespan of the entire system.

[0003] The frame of a photovoltaic module plays an indispensable role in the overall module structure. It not only provides a necessary protective barrier for the fragile solar cells, ensuring that the cells are not affected by adverse factors such as external physical impact and moisture corrosion, but also bears the heavy responsibility of supporting the overall structure of the module, so that the module can maintain a stable shape in various installation environments. It also provides convenient conditions for the installation operation of the module, making it easy to install it accurately and firmly on the bracket or other support structure.

[0004] Currently, most conventional photovoltaic (PV) frames are made of aluminum alloy. In terms of weight, aluminum alloy is relatively heavy for the same volume, making it unsuitable for installation scenarios with high load requirements. Secondly, aluminum alloy is a good conductor, requiring grounding protection during installation. If the grounding protection measures are inadequate or fail, electrical faults (such as leakage or lightning strikes) may increase the risk of electric shock to personnel and may also damage PV modules and related equipment, affecting the normal operation of the PV power generation system and thus reducing power generation revenue. In addition, the "A-side" (usually the surface exposed to the external environment and easily affected) of commercially available PV module frames is prone to accumulating dirt and sand, affecting the power generation of the PV module. Therefore, a lightweight composite PV module frame is proposed to solve the above problems. Summary of the Invention

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Referring to Figures 1-3, one embodiment of this utility model is provided: a lightweight photovoltaic module composite frame, including a frame 1, which serves as the main structure of the entire composite frame. The frame 1 provides direct physical support and protection for the lightweight photovoltaic module 2. The shape and size of the frame 1 are designed to match the lightweight photovoltaic module 2, ensuring that the module can be accurately installed and remain stable. The lightweight photovoltaic module 2 is installed on the upper part of the frame 1, which is the core part of photovoltaic power generation. It converts light energy into electrical energy through the photoelectric effect. This technology is existing technology, so it will not be described in detail. A support mechanism is provided on the outside of the frame 1. The support mechanism includes a fixing component and a reinforcing component. The fixing component includes a connecting plate 32, which serves to connect the frame 1 and the reinforcing member 42, providing an installation base for the reinforcing member. The fixing connection with the reinforcing member 42 is achieved by using rivets 41 passing through through holes 35, which enhances the stability and strength of the entire frame structure.

[0033] Furthermore, the connecting plate 32 is fixedly connected to the outside of the frame 1. The inner wall of the frame 1 has a cavity 31 to reduce weight and optimize structural strength. The upper inner edge of the frame 1 and the side of the lightweight photovoltaic module 2 are set as an overflow groove 33, which is used to fill excess glue or sealant during the installation of the photovoltaic module to ensure the sealing performance after the module is installed. It can flatten the "A side" of the photovoltaic module frame and prevent the accumulation of mud and sand, thereby maintaining the power generation performance of the photovoltaic module. The upper side of the connecting plate 32 has a through hole 35, which provides a fixed connection position for the rivet 41. By passing the rivet 41 through the through hole 35, the reinforcing member 42 can be firmly installed on the connecting plate 32 to achieve a tight connection between the reinforcing component and the fixed component. Multiple sets of through holes 35 are provided. The lower side of the connecting plate 32 is fixedly connected to the outside of the frame 1 with a support plate 34. Multiple sets of support plates 34 are evenly arranged on the outside of the frame 1. The support plates 34 are triangular in shape, which can effectively enhance the connection strength and rigidity between the frame 1 and the connecting plate 32.

[0034] Referring to Figures 4 and 5, the reinforcing component includes a reinforcing member 42, which is disposed on the upper side of the connecting plate 32. The vertical cross-section of the reinforcing member 42 is U-shaped, which has high structural strength and bending resistance. After being installed on the upper side of the connecting plate 32, the number can be added according to the actual situation, providing additional vertical and lateral support for the frame 1, and connecting the two sets of frames 1 to increase the stability of the device. Multiple through holes 35 are opened on the top of the left and right sides of the reinforcing member 42. The connecting plate 32 and the reinforcing member 42 are fixedly installed by rivets 41, which firmly fix the reinforcing member 42 to the connecting plate 32. The rivets 41 are disposed inside the through holes 35. The frame 1 is made of a polymer composite material, such as fiber-reinforced material, which has good insulation performance, so that grounding is not required when installing photovoltaic modules, simplifying the installation process and reducing costs. At the same time, its light weight makes it suitable for installation scenarios with high load requirements, reducing the pressure on the installation foundation.

[0035] Referring to Figures 3-5, an auxiliary component is provided on the outer side of the reinforcing member 42. The auxiliary component includes a mounting block 51, which is fixedly connected to the outer side of the mounting block 51. A screw 52 provides the mounting base and support structure. The screw 52 is threadedly connected to the inner wall of the mounting block 51. A handle is provided on the lower side of the mounting block 51. When the operator rotates the screw 52 by the handle, the screw 52 moves up and down under the action of the thread in the mounting block 51, thereby achieving precise and stable support for the lightweight photovoltaic module 2. A stabilizing pad 53 is rotatably connected to the top of the screw 52. The stabilizing pad 53 slides on the upper inner wall of the mounting block 51, and the top of the stabilizing pad 53 is attached to the lower side of the lightweight photovoltaic module 2. The stabilizing pad 53 is made of rubber and has good flexibility, friction and cushioning performance. Driven by the screw 52, ​​the stabilizing pad 53 can closely contact the lightweight photovoltaic module 2 and provide stable support force, ensuring that the weight of the module can be evenly distributed, improving the stability and reliability of the support, and ensuring that the lightweight photovoltaic module 2 always maintains a good working condition during long-term use.

[0036] Working principle: During use, the lightweight photovoltaic module 2 is placed on the upper part of the frame 1, and glue or sealant is used to fill the overflow groove 33 to ensure the sealing effect between the module and the frame 1. This effectively prevents moisture, dust and other impurities from entering the module and affecting the photoelectric conversion efficiency and module life. At the same time, it can also flatten the "A side" of the photovoltaic module frame, avoid the accumulation of mud and sand, thereby maintaining the power generation performance of the photovoltaic module, extending the service life of the photovoltaic module, and ensuring the long-term stable operation of the photovoltaic power generation system.

[0037] Meanwhile, the frame 1 is made of high-polymer composite materials such as fiber-reinforced materials. Its excellent insulation properties eliminate the need for grounding during subsequent installation, simplifying the installation process and reducing costs. At the same time, its lightweight nature is also beneficial for the installation and layout of the entire photovoltaic module system.

[0038] Meanwhile, the reinforcing member 42 is fixedly installed on the upper side of the connecting plate 32 by rivets 41 to tightly connect the two. The vertical cross section of the reinforcing member 42 is U-shaped, which has high structural strength and bending resistance. After installation, it can not only provide additional vertical and lateral support for the frame 1, but also connect the two sets of frames 1, further increasing the overall stability of the device and ensuring the safety of the lightweight photovoltaic module 2 in complex environments.

[0039] The operator rotates the handle on the lower side of the mounting block 51, which drives the screw 52 to move up and down under the action of the thread on the inner wall of the mounting block 51. This makes the top of the stabilizing pad 53 fit tightly against the lower side of the lightweight photovoltaic module 2, which can evenly distribute the weight of the lightweight photovoltaic module 2 and achieve precise and stable support for the lightweight photovoltaic module 2.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
