Description

Technical Field

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

[0002] Photovoltaic panels, also known as solar panels, are devices that convert sunlight into electrical energy. Their core component is the solar cell. Photovoltaic panels utilize the photoelectric effect, where photons strike metal or semiconductor materials, causing electrons to absorb energy, transition, and generate a potential difference, which in turn forms an electric current, thus converting light energy into direct current. This technology is widely used in energy supply for homes, businesses, and industries, and is an important form of solar energy utilization.

[0003] However, existing photovoltaic (PV) panels are typically installed on a mounting platform using bolts. Bolt installation is prone to loosening due to improper installation, is cumbersome, and hinders subsequent disassembly, inspection, and maintenance. Therefore, those skilled in the art have provided a PV panel installation structure to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic panel installation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A photovoltaic panel mounting structure includes: a mounting frame with a cavity inside, wherein a photovoltaic panel, a photovoltaic backsheet, and a dustproof plate are sequentially arranged inside the cavity, wherein the photovoltaic panel is attached to the cavity wall, and the photovoltaic backsheet and the dustproof plate are sequentially attached to the lower end face of the photovoltaic panel; and L-shaped limiting plates are provided at both ends of the bottom of the mounting frame, a push plate is provided on the inner side of the L-shaped limiting plate, and a threaded rod is rotatably mounted on the lower end face of the push plate, the end of the threaded rod away from the push plate is threaded inside the L-shaped limiting plate and extends below it, and the push plate can slide into the cavity and press tightly against the lower end face of the dustproof plate by rotating the threaded rod.

[0007] Preferably, the upper surface of the mounting frame has an opening that communicates with the cavity, and the end face of the photovoltaic panel comes into contact with external sunlight through the opening.

[0008] Preferably, a sealing gasket is provided around the outside of the opening on the cavity wall, and the photovoltaic panel is tightly attached to the cavity wall through the sealing gasket.

[0009] Preferably, the inner wall of the L-shaped limiting plate has a groove between it and the lower end face of the mounting frame, the push plate is installed inside the groove, and the distance between the push plate and the lower end face of the mounting frame is greater than the height of the photovoltaic panel, the photovoltaic backsheet and the dustproof plate.

[0010] Preferably, a threaded hole is provided at the middle position of the end face of the L-shaped limiting plate, and the threaded rod is threadedly installed inside the threaded hole and extends to the bottom of the L-shaped limiting plate.

[0011] Preferably, the outer wall of the threaded rod is provided with limit nuts at both the upper and lower ends of the L-shaped limit plate, and the two limit nuts are threaded onto the outer wall of the threaded rod and respectively attached to the upper and lower ends of the L-shaped limit plate.

[0012] Preferably, the internal threads of the two limiting nuts are in opposite directions.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting up an installation frame, during the installation of the photovoltaic panel, the photovoltaic panel, photovoltaic backsheet, and dustproof plate can be placed sequentially into the cavity inside the installation frame. Then, the threaded rod is tightened, allowing it to move inwards through the threaded hole. The moving threaded rod pushes a push plate mounted on it into the cavity, pressing it tightly against the lower end face of the dustproof plate. This presses the dustproof plate, photovoltaic backsheet, and photovoltaic panel sequentially against the inner wall of the cavity. Finally, the two limit nuts on the threaded rod are tightened, ensuring they are firmly against the inner and outer sides of the L-shaped limit plate. Tightening the threaded rod prevents displacement, thus completing the installation of the photovoltaic panel. By clamping the photovoltaic panel in the mounting frame, the installation method of the photovoltaic panel is changed. This not only avoids the situation where the threads on the bolts are damaged due to repeated disassembly and removal, making it impossible to securely fix the photovoltaic panel, but also avoids the trouble of repeatedly disassembling and assembling multiple bolts to complete the installation and removal of the photovoltaic panel. The structure is simple and easy to disassemble and assemble, which facilitates the later maintenance work. Moreover, the sealing gasket seals the gap between the photovoltaic panel and the inner wall of the cavity, which can also prevent rainwater from entering the mounting frame through the gap between the photovoltaic panel and the inner wall of the cavity and corroding the electronic components, thus protecting the electronic components on the photovoltaic panel.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] Combination Figures 1-3 As shown, the mounting frame 1 has a cavity 101 inside. A photovoltaic panel 2, a photovoltaic backsheet 3, and a dustproof plate 4 are arranged sequentially inside the cavity 101. The photovoltaic panel 2 is attached to the cavity wall of the cavity 101. The photovoltaic backsheet 3 and the dustproof plate 4 are attached to the lower end face of the photovoltaic panel 2. Furthermore, L-shaped limiting plates 11 are provided at both ends of the bottom of the mounting frame 1. A push plate 12 is provided on the inner side of the L-shaped limiting plate 11. A threaded rod 13 is rotatably installed on the lower end face of the push plate 12. The end of the threaded rod 13 away from the push plate 12 is threaded inside the L-shaped limiting plate 11 and extends below it. The push plate 12 can slide into the cavity 101 and press tightly against the lower end face of the dustproof plate 4 by rotating the threaded rod 13.

[0021] In one embodiment, since the distance between the push plate 12 and the lower end face of the mounting frame 1 is greater than the height of the photovoltaic panel 2, the photovoltaic backsheet 3, and the dustproof plate 4, when placing the photovoltaic panel 2, the photovoltaic backsheet 3, and the dustproof plate 4 into the mounting frame 1, the photovoltaic panel 2 can be first inserted into the slot between the push plate 12 and the mounting frame 1 in the cavity 111, allowing the photovoltaic panel 2 to enter the mounting frame 1 from the opening of the cavity 101. Then, the photovoltaic backsheet 3 can be inserted into the slot between the push plate 12 and the mounting frame 1, allowing the photovoltaic backsheet 3 to enter the mounting frame 1 from the opening of the cavity 101. The dustproof plate 4 is inserted into the mounting frame 1 and attached to the lower end face of the photovoltaic panel 2. Finally, the dustproof plate 4 is inserted into the groove between the push plate 12 and the mounting frame 1, allowing the dustproof plate 4 to enter the mounting frame 1 from the opening of the cavity 101 and attach to the lower end face of the photovoltaic backsheet 3. This allows the photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4 to be installed into the mounting frame 1 without the L-shaped limiting plate 11 interfering with the installation of the photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4, thus ensuring the smooth installation of the photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4.

[0022] In one embodiment, when limiting the position of the installed photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4, the threaded rod 13 can be directly turned to move it into the mounting frame 1 through the threaded hole 112. The moving threaded rod 13 pushes the push plate 12 mounted on it to slide into the cavity 101 and press it tightly against the lower end face of the dustproof plate 4, thus pressing the dustproof plate 4, photovoltaic backsheet 3, and photovoltaic panel 2 sequentially against the inner wall of the cavity 101. Then, the two limiting nuts 131 on the threaded rod 13 are turned to press them tightly against the inner and outer sides of the L-shaped limiting plate 11, respectively. Tightening the threaded rod 13 limits its position, thus completing the process. The limiting mechanism for the paired photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4 clamps them within the mounting frame 1, altering their installation method and preventing direct contact between them and the bolts. This avoids damage to the threads caused by repeated bolt disassembly, which could lead to insecure installation of the photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4. It also avoids the hassle of repeatedly disassembling and reassembling multiple bolts to complete the installation and removal of the photovoltaic panel 2, photovoltaic backsheet 3, and dustproof plate 4. The structure is simple, and the installation and removal are convenient, facilitating subsequent maintenance.

[0023] In one embodiment, since the internal threads of the two limiting nuts 131 are opposite, when limiting the push plate 12 after adjustment, the two limiting nuts 131 on the threaded rod 13 can be directly screwed on, so that the two limiting nuts 131 are tightly attached to the inner and outer sides of the L-shaped limiting plate 11 respectively, and the threaded rod 13 is tightened to limit the position of the threaded rod 13 and prevent the threaded rod 13 from shifting. This avoids the situation where the position of the push plate 12 changes due to the displacement of the threaded rod 13, causing the photovoltaic panel 2, photovoltaic backplate 3 and dustproof plate 4 inside the mounting frame 1 to become loose, thus ensuring the stability of the installation of the photovoltaic panel 2, photovoltaic backplate 3 and dustproof plate 4 and making it highly practical.

[0024] In one embodiment, after the photovoltaic panel 2 is installed into the mounting frame 1, the sealing gasket 14 can seal the gap between the photovoltaic panel 2 and the inner wall of the cavity 101 to prevent rainwater from flowing through the gap between the photovoltaic panel 2 and the inner wall of the cavity 101 from the opening 102 and entering the mounting frame 1 to corrode the electronic components. This avoids the situation where the photovoltaic panel 2 is damaged due to rainwater entering the mounting frame 1 and corroding the electronic components, thus ensuring the use of the photovoltaic panel 2 and protecting the electronic components on the photovoltaic panel 2.

[0025] The working principle of this utility model is as follows: When installing the photovoltaic panel 2, the photovoltaic panel 2 can first be inserted into the slot between the push plate 12 and the mounting frame 1 in the slot 111, allowing the photovoltaic panel 2 to enter the mounting frame 1 from the opening of the cavity 101. Then, the photovoltaic back sheet 3 is inserted into the slot between the push plate 12 and the mounting frame 1, allowing the photovoltaic back sheet 3 to enter the mounting frame 1 from the opening of the cavity 101 and adhere to the lower end face of the photovoltaic panel 2. Finally, the dustproof plate 4 is inserted into the push plate 12. In the groove between plate 12 and mounting frame 1, the dustproof plate 4 enters the mounting frame 1 from the opening of cavity 101 and adheres to the lower end face of photovoltaic backsheet 3, completing the installation of photovoltaic panel 2, photovoltaic backsheet 3 and dustproof plate 4. Then, the threaded rod 13 is turned, allowing the threaded rod 13 to move into the interior of mounting frame 1 in threaded hole 112. The moving threaded rod 13 pushes the push plate 12 mounted on it to slide into cavity 101 and press tightly against the lower end face of dustproof plate 4, thus installing dustproof plate 4. The photovoltaic backsheet 3 and photovoltaic panel 2 are pressed sequentially against the inner wall of the cavity 101. The sealing gasket 14 seals the gap between the photovoltaic panel 2 and the inner wall of the cavity 101, preventing rainwater from entering the mounting frame 1 through the gap between the photovoltaic panel 2 and the inner wall of the cavity 101 and corroding the electronic components. Then, the two limiting nuts 131 on the threaded rod 13 are turned so that the two limiting nuts 131 are tightly attached to the inner and outer sides of the L-shaped limiting plate 11 respectively. The threaded rod 13 is tightened to limit the position of the threaded rod 13, thus completing the installation of the photovoltaic panel 2. The photovoltaic panel 2 can be clamped in the mounting frame 1, changing the installation method of the photovoltaic panel 2 and preventing the photovoltaic panel 2 from directly contacting the bolts. This not only avoids the situation where the threads on the bolts are damaged due to repeated disassembly and reassembly, resulting in an unstable installation of the photovoltaic panel 2, but also avoids the trouble of repeatedly disassembling and reassembling multiple bolts to complete the installation and disassembly of the photovoltaic panel 2. The structure is simple, the disassembly and assembly are convenient, and the later maintenance work is convenient.
