Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel frame technology, specifically to a photovoltaic panel aluminum alloy frame connection structure. Background Technology

[0002] Photovoltaic panels, as the core component of photovoltaic power generation systems, directly convert solar energy into electrical energy and are key equipment for achieving efficient utilization of solar energy.

[0003] Nowadays, to enhance the structural strength of photovoltaic panels, protect internal components from external environmental damage, and facilitate installation and maintenance, frames are typically installed around the perimeter of the panels. These frames not only provide necessary mechanical support, preventing deformation or damage during transportation, installation, and use due to external forces, but also act as a sealing barrier, effectively blocking the intrusion of moisture, dust, and other impurities, thus extending the lifespan of the photovoltaic panels. The installation of the frames generally involves precisely splicing four pre-processed aluminum alloy frame strips into a rectangular frame by applying adhesive to the edges, and then firmly fixing it to the edge of the photovoltaic panel, ensuring the overall structural stability and airtightness.

[0004] However, since photovoltaic panels are exposed to the elements for extended periods, they inevitably face extreme weather conditions such as wind, snow, hail, and sandstorms. These environmental factors not only directly impact the surface of the photovoltaic panel but also exert complex tensile and torsional forces on the frame. This is especially true when the frame consists of four independent frame strips connected by adhesive, making the connection points often the weakest points in the structure. Over time, these tensile forces can cause the adhesive layer between the frame strips and the photovoltaic panel to age and crack, or even deform or break the frame strips themselves, ultimately leading to the frame strips detaching from the photovoltaic panel and severely impacting the power generation efficiency and safety of the photovoltaic panel. Therefore, we propose an aluminum alloy frame connection structure for photovoltaic panels to effectively address these drawbacks. Utility Model Content

[0005] The purpose of this utility model is to provide a photovoltaic panel aluminum alloy frame connection structure to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a photovoltaic panel aluminum alloy frame connection structure, including a frame strip, the frame strip being U-shaped, a mounting seat being fixedly provided on the inner side of the frame strip, the mounting seat being 7-shaped, a mounting cavity being formed between the frame strip and the mounting seat, and connectors being detachably connected to the openings at both ends of the mounting cavity, the connectors being used to connect different frame strips.

[0007] Optionally, the connector is L-shaped, with its two ends inserted into different mounting cavities. The shape of the connector within the mounting cavity matches the shape of the mounting cavity, and the end shape of the connector is V-shaped.

[0008] Optionally, the connector has an internal hollow structure, and an installation port is provided on the inner side wall of the connector. A spring sheet is fixedly connected in the installation port, and a limit block is fixedly connected to the movable end of the spring sheet. A limit port for the limit block to be inserted is provided on the mounting base.

[0009] Optionally, the side of the limiting block facing the spring sheet is a first plane, and the side of the limiting block facing away from the spring sheet is a second plane. The width of the first plane is greater than the width of the second plane, and one side of the first plane is located outside the connector.

[0010] Optionally, a slider is fixedly provided on the outer side wall of the connector, and a notch is provided on the edge of the side wall of the frame strip. The notch is used for the slider to slide into the frame strip along its length. One side of the slider extends out of the frame strip and is fixedly connected to a protective cover. The protective cover is used to cover the end of the frame strip.

[0011] Optionally, the protective cover has a cross-sectional shape of U-shape, and the top projection shape of the protective cover is L-shaped, with the edges on the outer side of the protective cover being rounded.

[0012] Compared with the prior art, this utility model provides a photovoltaic panel aluminum alloy frame connection structure, which has the following beneficial effects:

[0013] 1. This utility model provides a connector at the end of the frame strip, and uses a spring sheet and a limiting block. After the limiting block is inserted into the limiting hole, it can connect the connector and the frame strip together. At the same time, the connector is L-shaped, and its two ends can be connected to different frame strips through corresponding limiting blocks, so that the ends of the frame strips can be connected together, thereby making the frame strip more secure after it is installed on the photovoltaic panel.

[0014] 2. This utility model provides a protective cover on the connector, so that after the connector is inserted into the installation cavity, the protective cover can just cover the end of the frame.

[0021] 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.

[0022] Please see Figure 1 - Figure 5 A photovoltaic panel aluminum alloy frame connection structure includes a frame strip 1, which is U-shaped. A mounting base 101, which is 7-shaped, is fixedly provided on the inner side of the frame strip 1. The mounting base 101 is fixedly connected to the side wall and bottom wall of the frame strip 1. There is a gap between the top wall of the mounting base 101 and the top wall of the frame strip 1, and the edge of the photovoltaic panel is installed in the gap.

[0023] On the other hand, both the frame strip 1 and the mounting base 101 are made of aluminum alloy. The thickness of the frame strip 1 is 1 to 2 mm, the thickness of the mounting base 101 is 0.5 to 1.5 mm, and the distance between the top wall of the mounting base 101 and the top wall of the frame strip 1 is 4 to 6 mm, which is compatible with the thickness of the photovoltaic panel installed on the frame strip 1.

[0024] Furthermore, the side wall and bottom wall of the frame strip 1 and the mounting base 101 form a mounting cavity 102. Both ends of the mounting cavity 102 are detachably connected to connectors 2. Connectors 2 are used to connect different frame strips 1 so that two different frame strips 1 can be connected together through connectors 2.

[0025] In this embodiment, the connector 2 is L-shaped, and its two ends are respectively inserted into different mounting cavities 102. The shape of the connector 2 within the mounting cavity 102 is adapted to the shape of the mounting cavity 102. Specifically, when the connector 2 is inserted into the mounting cavity 102, its four sidewalls (top, bottom, left, and right) respectively fit against the four sidewalls of the mounting cavity 102. Furthermore, the end of the connector 2 is V-shaped to ensure precise insertion into the mounting cavity 102.

[0026] The connector 2 is also made of aluminum alloy to improve the overall strength of the connector 2 and extend its service life.

[0027] Specifically, connector 2 has an internal hollow structure. An installation port 201 is provided on the inner sidewall of connector 2. A spring plate 202 is fixedly connected inside the installation port 201. A limit block 203 is fixedly connected to the movable end of the spring plate 202. A limit port 101 is provided on the mounting base 101 for the limit block 203 to be inserted. The sidewall thickness of connector 2 is 0.5–1.5 mm, the thickness of spring plate 202 is 0.4–1.2 mm, and the installation port 201 is made of stainless steel, which has excellent corrosion resistance and high strength, preventing loss of elasticity or weak connection due to rust.

[0028] Furthermore, the side of the limiting block 203 facing the spring sheet 202 is a first plane, and the side of the limiting block 203 opposite to the spring sheet 202 is a second plane. The width of the first plane is greater than the width of the second plane, and one side of the first plane is located outside the connector 2. Figure 2 and Figure 5 As shown, the limiting block 203 is a wedge-shaped block, with one side of the first plane extending into the limiting opening 1011. The width of the first plane is more than twice the width of the second plane. When the connector 2 is inserted into the mounting cavity 102, the inclined surface on the limiting block 203 abuts against the inner wall of the mounting cavity 102, and the spring sheet 202 is squeezed and bent, thereby pressing the limiting block 203 into the inner cavity of the connector 2. When one end of the connector 2 is fully inserted into the mounting cavity 102, the limiting block 203 just reaches the limiting opening 1011, and the spring sheet 202 will reset, causing the limiting block 203 to embed into the limiting opening 1011, thereby fixing the connector 2 and the frame strip 1 together.

[0029] It is worth mentioning that a slider 204 is fixedly provided on the outer wall of the connector 2, and a notch 103 is opened along the length direction of the side wall edge of the frame strip 1. The notch 103 is used for the slider 204 to slide into the frame strip 1 along its length direction. One side of the slider 204 extends out of the frame strip 1 and is fixedly connected to a protective cover 205, so that when the connector 2 is inserted into the mounting cavity 102, the protective cover 205 will simultaneously cover the outside of the frame strip 1. The protective cover 205 is used to cover the end of the frame strip 1.

[0030] Specifically, the protective cover 205 has a cross-sectional shape of U-shape, and the top projection shape of the protective cover 205 is L-shaped. The edges on the outer side of the protective cover 205 are set as rounded corners.

[0031] The protective cover 205 is made of EPDM (ethylene propylene diene monomer) rubber with a thickness of no less than 1.8 mm to provide good anti-aging and cushioning capabilities. When the connector 2 is inserted into the mounting cavity 102, the protective cover 205 covers the outer side of the end of the frame strip 1, and the inner wall of the protective cover 205 fits tightly against the outer wall of the frame strip 1, further improving the stability of the frame strip 1 after connection. Simultaneously, the protective cover 205 protects the end of the frame strip 1, preventing damage from friction with the ground during transport of the frame and photovoltaic panels, and also preventing workers from impacting the end of the frame, thus improving overall safety.

[0032] Application scenarios and operation procedures of this utility model: Before transporting and installing the photovoltaic panel into the photovoltaic power station, the frame strip 1 needs to be installed on the edge of the photovoltaic panel to protect it.

[0033] In use, firstly, insert the two connectors 2 into both ends of a frame strip 1. As one end of the connector 2 enters the mounting cavity 102, the limiting block 203 is pressed into the inner cavity of the connector 2 until one end of the connector 2 is fully inserted into the mounting cavity 102. At this point, the limiting block 203 just reaches the limiting opening 1011. Subsequently, the spring plate 202 will return to its original position due to its own elasticity, thereby embedding the limiting block 203 into the limiting opening 1011, completing the fixation of the connector 2 and a frame strip 1. During this process, the protective cover 205 will be simultaneously placed on the outer side of the end of the frame strip 1. Then, the frame strip 1 with the connector 2 already installed is fitted onto the symmetrical side of the photovoltaic panel, and the remaining two frame strips 1 are fitted onto the edge of the photovoltaic panel along the side length direction, with these two frame strips 1 perpendicular to the already installed frame strip 1. After the above installation process, the other end of the connector 2 will be inserted into the mounting cavity 102 of the two frame strips 1, thereby completing the installation and connection of the three frame strips 1. For the last frame strip 1, first insert the two connectors 2 into both ends of the frame strip 1, and then put the last frame strip 1 on in a direction perpendicular to the last side of the photovoltaic panel. This will allow all four connectors 2 to be inserted into the mounting cavity 102 of the corresponding frame strip 1, thus realizing the installation and connection of the frame strip 1. The protective cover 205 will also be placed on the end of the frame to protect it.
