Description

Technical Field

[0001] This utility model relates to the field of solar energy, and in particular to a photovoltaic panel and a foldable photovoltaic device. Background Technology

[0002] Solar energy, as a clean and sustainable renewable energy source, has been increasingly widely used in recent years. However, the photovoltaic industry still faces challenges such as limited installation space and insufficient resistance to severe weather. To address these challenges, existing technologies, such as Chinese utility model patent CN220964767U, disclose a dual-axis tracking photovoltaic device with a folding wind-resistant function. This device can be installed on pole structures such as streetlights, and by folding and retracting the photovoltaic modules, the windward area is reduced, effectively alleviating space constraints and improving safety under extreme weather conditions.

[0003] However, in practical applications, it has been found that when using existing photovoltaic panels, foldable photovoltaic devices suffer from problems such as insufficient structural rigidity and poor connection stability. Under external disturbances such as wind loads, the modules are prone to swaying, leading to fatigue damage or the risk of detachment, which has become a key technical problem that urgently needs to be solved. Utility Model Content

[0004] This invention first proposes a photovoltaic panel to solve the above-mentioned problems. Secondly, this invention proposes a foldable photovoltaic device.

[0005] As a first aspect of this utility model, a photovoltaic panel is proposed, comprising a photovoltaic cell and a main frame, wherein the main frame comprises at least one first rod and at least one second rod, the first rod and the second rod being fixedly connected, and the first rod being provided with a first sleeve portion;

[0006] It also includes at least one extension rod, one end of which is provided with a second socket for cooperating with the first socket, the first socket and the second socket are fixedly connected, and the other end of the extension rod is fixedly connected to the photovoltaic cell.

[0007] Preferably, there are two first rods arranged in parallel; there are two second rods arranged in parallel; the first rods and the second rods are perpendicular to each other.

[0008] Preferably, the end of the first rod is fixedly connected to the photovoltaic panel, and the end of the second rod is fixedly connected to the first rod.

[0009] Preferably, the main frame and / or the extension rod are made of aluminum alloy.

[0010] Preferably, the number of extension rods is four.

[0011] Preferably, the first socket and the second socket are fixedly connected by a threaded component.

[0012] As a second aspect of this utility model, a foldable photovoltaic device is proposed, including the photovoltaic panel described above, and also including a first drive shaft and a column;

[0013] The fixed end of the first drive shaft is fixedly connected to the column, and the output end of the first drive shaft is fixedly connected to the photovoltaic panel.

[0014] Preferably, the device further includes a second drive shaft and a clutch, wherein the fixed end of the second drive shaft is fixedly connected to the output end of the first drive shaft, the output end of the second drive shaft is fixedly connected to the clutch, and the clutch is fixedly connected to the photovoltaic panel.

[0015] Preferably, the clutch is fixedly connected to one end of the first rod of the photovoltaic panel.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The extension rod and main frame are detachably connected through the cooperation of the first and second sockets, reducing the photovoltaic panel's reliance on welding processes, shortening the manufacturing cycle, and avoiding structural precision deviations caused by welding heat deformation. This design allows the modules to be compactly disassembled during transportation, improving space utilization and reducing logistics costs. No specialized welding equipment is required for on-site installation; the first and second sockets are connected by threads, supporting rapid modular assembly and extending the system's lifecycle flexibility.

[0018] 2. The vertically positioned first and second poles, along with the parallel double first and double second poles, construct a stable three-dimensional support frame. This evenly distributes external stresses such as wind and snow loads to each member, improving structural rigidity, effectively suppressing the swaying of photovoltaic modules, and significantly reducing the risk of fatigue damage at connection points. In strong wind environments, the overall torsional resistance of the device is significantly enhanced, ensuring long-term operational stability and providing a solid guarantee for the reliable application of photovoltaic devices in harsh climate regions.

[0019] 3. The main frame and extension rods are made of high-strength aluminum alloy, replacing traditional steel pipe supports that are prone to corrosion. The inherent excellent corrosion resistance of aluminum alloy eliminates the need for additional galvanizing or spraying in humid, high-salt-spray outdoor environments, directly avoiding the strength reduction problems caused by coating peeling and rust. This not only reduces maintenance costs but also extends the service life of the support, while the lightweight design further simplifies the installation process. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] As the first aspect of this specific embodiment, such as Figures 1 to 4 As shown, a photovoltaic panel 1 is proposed, including a photovoltaic cell 15 and a main frame 11. The main frame 11 includes at least one first rod 111 and at least one second rod 112. The first rod 111 and the second rod 112 are fixedly connected. The first rod 111 is provided with a first sleeve portion 13. It should be emphasized that, in this specific embodiment, unless otherwise specified, the fixed connection includes both detachable fixed connection and non-detachable fixed connection. This aspect will not be elaborated further later.

[0031] It also includes at least one extension rod 12, one end of which is provided with a second socket 14 for cooperating with the first socket 13, the first socket 13 and the second socket 14 are fixedly connected, and the other end of the extension rod 12 is fixedly connected to the photovoltaic cell 15.

[0032] The extension rod 12 and the main frame 11 are detachably connected by the cooperation of the first socket 13 and the second socket 14, which reduces the photovoltaic panel 1's dependence on welding processes, shortens the manufacturing cycle, and avoids structural accuracy deviations caused by welding heat deformation. This design allows the components to be compactly disassembled during transportation, improving space utilization and reducing logistics costs. No specialized welding equipment is required for on-site installation; the first socket 13 and the second socket 14 are connected by threads, supporting rapid modular assembly and extending the system's lifecycle flexibility.

[0033] In such Figure 2 and Figure 3 In some embodiments shown, there are two first rods 111, arranged in parallel; there are also two second rods 112, arranged in parallel; the first rods 111 and the second rods 112 are perpendicular. The perpendicularly arranged first rods 111 and second rods 112, together with the parallel arrangement of the two first rods 111 and two second rods 112, construct a stable three-dimensional support frame. External stresses such as wind loads and snow loads are evenly distributed to each member, improving structural rigidity, effectively suppressing the swaying of photovoltaic modules, and significantly reducing the risk of fatigue damage at connection points. In strong wind environments, the overall torsional resistance of the device is significantly enhanced, ensuring long-term operational stability and providing a solid guarantee for the reliable application of photovoltaic devices in harsh climate areas.

[0034] In other embodiments, the position and number of the first rod 111 remain unchanged, while the number of the second rods 112 remains unchanged but the structure is arranged in an "X" shape. The ends of the two second rods 112 are also fixedly connected to the first rod 111, achieving a similar technical effect. The number of the first rods 111 and the structure formed by the fixed connection of the second rods 112 are diverse, and will not be elaborated on here.

[0035] In some embodiments, the end of the first rod 111 is fixedly connected to the photovoltaic panel 1, and the end of the second rod 112 is fixedly connected to the first rod 111.

[0036] In some embodiments, the main frame 11 and / or extension rod 12 are made of aluminum alloy. The main frame 11 and extension rod 12 utilize high-strength aluminum alloy, replacing traditional steel pipe supports that are prone to corrosion. The inherent excellent corrosion resistance of aluminum alloy eliminates the need for additional galvanizing or spraying in humid, high-salt-spray outdoor environments, directly avoiding the strength reduction problems caused by coating peeling and rust. This not only reduces maintenance costs but also extends the service life of the support, while the lightweight design further simplifies the installation process.

[0037] In such Figure 2 and Figure 3In some embodiments shown, there are four extension rods 12, with the ends of each extension rod 12 positioned at the vertices of the rectangular photovoltaic cell 15. Firstly, the four extension rods 12 are symmetrically distributed at the four vertices of the photovoltaic cell 15, achieving uniform stress distribution on the structure, preventing bending deformation of the photovoltaic panel 1, effectively improving the stability and wind load resistance of the overall support structure, and reducing deformation or damage caused by external environmental stress. Secondly, this layout facilitates installation and positioning, enabling modular design and rapid assembly, reducing construction difficulty and maintenance costs. Furthermore, the connection structure between the extension rods 12 and the vertices effectively disperses stress concentration, extending the service life of the photovoltaic panel 1 and improving the safety and reliability of the system.

[0038] In some embodiments, the first socket 13 and the second socket 14 are fixedly connected by a threaded connection. For example... Figure 4 In the illustrated embodiment, the first socket 13 is fitted inside the second socket 14. In some embodiments, the second socket 14 may be fitted inside the first socket 13. In other embodiments, a sleeve is also included, which fits both the first socket 13 and the second socket 14 inside the sleeve, and then the connection is fixed by a threaded component. All three solutions described above can achieve a detachable and fixed connection between the first socket 13 and the second socket 14.

[0039] like Figures 5 to 6 As shown, as a second aspect of this specific embodiment, a foldable photovoltaic device is proposed, including the photovoltaic panel 1 described above, and also including a first drive shaft 21 and a column 4;

[0040] The fixed end of the first drive shaft 21 is fixedly connected to the column 4, and the output end of the first drive shaft 21 is fixedly connected to the photovoltaic panel 1.

[0041] In such Figure 5 and Figure 6 In some embodiments shown, a second drive shaft 22 and a clutch 3 are also included. The fixed end of the second drive shaft 22 is fixedly connected to the output end of the first drive shaft 21, and the output end of the second drive shaft 22 is fixedly connected to the clutch 3. The clutch 3 is fixedly connected to the photovoltaic panel 1.

[0042] In some embodiments, the clutch 3 is fixedly connected to one end of the first rod 111 of the photovoltaic panel 1.
