Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a photovoltaic panel mounting frame that is easy to disassemble and maintain. Background Technology

[0002] Traditional photovoltaic module installation systems mainly adopt an aluminum alloy frame + fixed bracket + base structure. Although this structure is mature, it has several technical limitations in practical applications, such as optical efficiency issues. The alloy frame will block some incident light, affecting the power generation efficiency of the photovoltaic panel edge area. The metal frame is prone to static electricity and dust attraction, reducing light transmittance and requiring frequent cleaning. The fixed frame structure makes photovoltaic panel replacement and maintenance operations complicated. The disassembled aluminum alloy frame is prone to damage and cannot be reused, resulting in high costs. The exposed wiring system is also prone to aging and damage.

[0003] This technical solution addresses these issues by proposing a low-cost, easy-to-disassemble, and high-transmittance photovoltaic installation system. Utility Model Content

[0004] In view of the above, this utility model provides an easy-to-disassemble and maintain photovoltaic panel installation frame, with "transparent openable frame + hollow column + integrated installation box" as the core, which takes into account multiple requirements such as high light transmittance, lightweight and quick installation, easy maintenance and long life, and is especially suitable for distributed roofs, carports, balconies and other scenarios that require frequent inspection or expansion.

[0005] The present invention specifically adopts the following technical solution: an easily disassembled and repairable photovoltaic panel mounting frame, including a mounting frame and a bracket, wherein the photovoltaic panel is installed in the mounting frame, the mounting frame is a rectangular frame formed by two first connecting plates and two second connecting plates connected end to end, the first connecting plates and the second connecting plates are connected end to end by a butterfly hinge, the first connecting plates and the second connecting plates are transparent plates, a mounting plate is provided at the bottom of the mounting frame, the bracket includes a main column and a branch column, the branch column extends obliquely from the upper side wall of the main column and connects to the lower part of the mounting plate, the mounting plate is provided at the top of the main column and the branch column, and a mounting box is provided below the main column.

[0006] As a further improved technical solution, the surfaces of the first connecting plate and the second connecting plate are provided with an antistatic coating.

[0007] As a further improved technical solution, the first connecting plate and the second connecting plate are made of PMMA or PC hardened plates.

[0008] As a further improved technical solution, the inner wall of the first connecting plate is provided with a longitudinal plate, and the longitudinal plate is provided with longitudinal connecting strips perpendicular to it; the inner wall of the second connecting plate is provided with a transverse plate, and the transverse plate is provided with transverse connecting strips perpendicular to it.

[0009] As a further improved technical solution, the main column and the branch column are hollow columns, and the mounting plate has wiring holes that communicate with the hollow columns.

[0010] As a further improved technical solution, the side of the mounting box is provided with downward-sloping heat dissipation holes, and both ends of the mounting box are provided with stepped fixing platforms, and the fixing platforms are provided with mounting holes.

[0011] As a further improved technical solution, the top of the mounting box is provided with a cover.

[0012] The easily disassembled and repairable photovoltaic panel mounting frame of this utility model has the following advantages:

[0013] Improved power generation efficiency: This application uses PMMA / PC transparent hardened board to replace the traditional aluminum alloy frame, eliminating the problem of shading of the edge area by the metal frame, allowing the photovoltaic panel to make fuller use of the incident sunlight. The nano antistatic coating sprayed on the surface of the mounting frame effectively reduces the static adsorption of dust, keeps the surface of the photovoltaic panel clean, and avoids the decline in power generation efficiency caused by dust accumulation. Moreover, the bracket design keeps the photovoltaic panel in an inclined state, which can achieve the best light energy absorption effect in most areas.

[0014] Easy to install and maintain: The modular frame structure and the frame design connected by butterfly hinges allow for quick installation and removal of photovoltaic panels. No complete disassembly is required during maintenance, which greatly saves maintenance time and labor costs. The integrated wiring design and hollow bracket structure hide the cables, which is not only aesthetically pleasing but also avoids the risk of wear and tear caused by exposed cables, while facilitating later inspection and maintenance.

[0015] Material cost optimization: Compared to aluminum alloy frames, transparent polymer materials are lower in cost and lighter, reducing transportation and installation costs. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0020] Reference Figures 1-2 This embodiment provides an easily disassembled and repairable photovoltaic panel mounting frame, including a mounting frame and a support. The photovoltaic panel is installed within the mounting frame. The mounting frame is a rectangular frame formed by two first connecting plates 1 and two second connecting plates 2 connected end to end. The first connecting plates 1 and 2 are connected end to end by a butterfly hinge 3, and the connection is sealed with a sealing gasket. The first connecting plates 1 and 2 are transparent plates. A mounting plate 4 is provided at the bottom of the mounting frame. The photovoltaic panel is installed within the mounting frame, with its light-receiving surface flush with the upper surface of the frame. The rectangular frame structure protects the sides and bottom of the photovoltaic panel. The support includes a main column 5 and a branch column 6. The branch column 6 extends obliquely from the upper side wall of the main column 5 and connects to the lower part of the mounting plate 4. The mounting plate 4 is located at the top of the main column 5 and the branch column 6, forming an oblique angle between the mounting frame and the main column 5, thus tilting the photovoltaic panel within the mounting frame for better light absorption. The tilt angle can be selected within the range of 45°-60°. A mounting box 7 is provided below the main column 5.

[0021] Specifically, the surfaces of the first connecting plate 1 and the second connecting plate 2 are coated with an antistatic coating, such as a nano-antistatic coating, to prevent dust from being attracted by static electricity, eliminating the need for frequent dust cleaning of the frames. The first connecting plate 1 and the second connecting plate 2 are made of PMMA or PC hardened boards, possessing waterproof, scratch-resistant, impact-resistant, sun-resistant, UV-resistant, anti-aging, and high light transmittance properties. The thickness of the first connecting plate 1 and the second connecting plate 2 is 5-15mm, suitable for providing protection for photovoltaic panels, improving upon the aluminum alloy structure in existing technologies, saving costs, and increasing light transmittance. Furthermore, a longitudinal plate 11 is fixedly installed on the inner wall of the first connecting plate 1, with a longitudinal connecting strip 12 perpendicular to it fixed on the longitudinal plate 11. A transverse plate 21 is fixedly installed on the inner wall of the second connecting plate 2, with a transverse connecting strip 22 perpendicular to it fixed on the transverse plate 21. Both the longitudinal connecting strip 12 and the transverse connecting strip 22 have threaded mounting holes for installing photovoltaic panels, allowing photovoltaic panels of compatible specifications to be fixed to the longitudinal connecting strip 12 and the transverse connecting strip 22 using bolts.

[0022] The main column 5 and the branch column 6 are hollow columns, made of hollow aluminum alloy tubes, which also serve as cable trays for cable routing. The mounting plate 4 has cable routing holes 41 that communicate with the hollow columns. The tops of the main column 5 and the branch column 6 are welded to the mounting plate 4. The bottom of the main column 5 has a circular flange, which is used to fix it to the top of the mounting box 7 with bolts, providing high stability.

[0023] The mounting box 7 is a stepped metal structure with a waterproof coating, such as polyurethane waterproof paint, to prevent rusting from rain. The sides of the mounting box 7 have downward-sloping ventilation holes 71 to prevent rainwater from entering while promoting air circulation for heat dissipation. Both ends of the mounting box 7 have stepped mounting platforms 72 with mounting holes for securing the box. The top of the mounting box 7 is sealed with a cover 73 using bolts and gaskets. The interior of the mounting box 71 can be used to house inverters, junction boxes, and other photovoltaic power generation components for convenient centralized management.

[0024] In use, connect the first connecting plate 1 and the second connecting plate 2 end to end via the butterfly hinge 3 to form a rectangular frame. Ensure the sealing gasket at the hinge is properly installed to prevent water ingress. Initially fix with bolts, but do not fully tighten them for later adjustment. Place the photovoltaic panel 7 into the frame, ensuring its light-receiving surface is flush with the upper surface of the frame. Secure the photovoltaic panel 7 with bolts through the threaded holes on the longitudinal connecting strip 12 and the transverse connecting strip 22. Check that the photovoltaic panel 7 is stable to prevent loosening. After confirming that the photovoltaic panel 7 is in the correct position, fully tighten the bolts of the butterfly hinge 3 to ensure the frame is sealed. Then, select a suitable location (such as the ground or roof) and secure the mounting box 7 with expansion bolts through the mounting holes of the stepped mounting platform. Keep the mounting box 7 level during installation; a level can be used for calibration. Align the flange at the bottom of the main column 5 with the top of the mounting box 7 and secure it with bolts, ensuring the main column 5 is vertically mounted on the mounting box 7. The branch columns 6 are welded or bolted to the main column 5 at an angle and extend to below the mounting plate 4 of the photovoltaic panel frame. Secure the frame to the mounting plate 4 with bolts, ensuring no shaking. The angled setting optimizes light absorption. The cables of the photovoltaic panel 7 enter the hollow bracket through the wiring holes at the bottom of the mounting frame and are finally connected to the terminals or inverter inside the mounting box 7, ensuring no exposed cables to avoid wear.
