Abstract
Description
Technical Field
[0001] This invention relates to a rooftop photovoltaic structure. Background Technology
[0002] Existing rooftop photovoltaic structures and installation methods cannot improve the overall strength and rigidity of the installed photovoltaic structure, resulting in poor stability, insignificant wind resistance, easy deformation, and difficulty in rapid assembly, requiring welding. Disassembled components cannot be reused, and the energy-saving effect is not outstanding. Summary of the Invention
[0003] The purpose of this invention is to provide a rooftop photovoltaic structure to solve the aforementioned technical problems.
[0004] The above objectives are achieved through the following technical solutions: A rooftop photovoltaic structure comprises a photovoltaic panel support column and a photovoltaic panel support base plate. The photovoltaic panel support base plate is fixed to the photovoltaic panel support column, the photovoltaic panel is fixed to the photovoltaic panel support base plate, the photovoltaic panel support diagonal brace is fixed to the photovoltaic panel support base plate and the photovoltaic panel support column, and a photovoltaic panel positioning guide rail is fixed to the photovoltaic panel support base plate.
[0005] In the aforementioned rooftop photovoltaic structure, a photovoltaic panel tilt angle positioning slider is installed on the photovoltaic panel positioning guide rail and is fixed by a photovoltaic panel tilt angle positioning pin and a positioning pin fixing nut.
[0006] The aforementioned rooftop photovoltaic structure includes a photovoltaic panel support surface that is hot-dip galvanized and then coated with a fluorocarbon coating.
[0007] The aforementioned rooftop photovoltaic structure includes a connecting piece for connecting the photovoltaic panel bracket base to the photovoltaic panel bracket support column. The bolt holes of the connecting piece are designed with gaps to adjust the position of the overall bracket to ensure the stability of the center of gravity and to ensure that the photovoltaic panels can be stably installed on uneven ground. Beneficial effects
[0008] 1. As the core support structure of a solar power generation system, the photovoltaic bracket of this invention directly affects the system's durability, lightweight design, and economic efficiency through its material selection. Given the current context of carbon emissions, the bracket is made of recycled carbon fiber, which is high-strength (tensile strength ≥3GPa), low-density (1.5-1.8g / cm³), and has a recyclability exceeding 95%. This material is used for lightweight brackets and flexible photovoltaic module support structures, reducing carbon emissions. The bracket surface treatment involves hot-dip galvanizing followed by a fluorocarbon coating, extending the salt spray resistance test time to 3000 hours (compared to 1000 hours for ordinary galvanizing).
[0009] 2. When the photovoltaic panel needs to be disassembled, the positioning bolts of the photovoltaic panel are loosened, and the photovoltaic panel can be removed or installed along the guide rail. The presence of the guide rail facilitates better positioning and installation of the photovoltaic panel, and also serves as a support. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of the present invention. Detailed Implementation
[0011] Reference Figure 1 A rooftop photovoltaic structure comprises a photovoltaic panel support column and a photovoltaic panel support base plate. The photovoltaic panel support base plate is fixed on the photovoltaic panel support column, the photovoltaic panel is fixed on the photovoltaic panel support base plate, the photovoltaic panel support diagonal brace is fixed on the photovoltaic panel support base plate and the photovoltaic panel support column, and a photovoltaic panel positioning guide rail is fixed on the photovoltaic panel support base plate.
[0012] The photovoltaic panel positioning guide rail is equipped with a photovoltaic panel tilt angle positioning slider, which is fixed by a photovoltaic panel tilt angle positioning pin and a positioning pin fixing nut.
[0013] The photovoltaic panel support surface is hot-dip galvanized and then sprayed with a fluorocarbon coating.
[0014] As the core support structure of a solar power generation system, the choice of materials for photovoltaic (PV) brackets directly affects the system's durability, lightweight design, and economic efficiency. Given the current carbon emission context, the brackets are made of recycled carbon fiber, which is high-strength (tensile strength ≥3GPa), low-density (1.5-1.8g / cm³), and has a recyclability exceeding 95%. This recycled carbon fiber is used for lightweight brackets and flexible PV module support structures, reducing carbon emissions. The bracket surface treatment involves hot-dip galvanizing followed by a fluorocarbon coating, extending the salt spray resistance test time to 3000 hours (compared to 1000 hours for ordinary galvanizing).
[0015] Item 20 is the photovoltaic panel bracket base, and item 19 is the connecting piece, used to connect the photovoltaic panel bracket base to the photovoltaic panel bracket support column. The bolt holes on the connecting piece are designed with gaps to adjust the overall bracket position to ensure stability and allow the photovoltaic panels to be placed stably on uneven ground. Items 17 and 18 are the connecting piece fixing bolts.
[0016] 1 and 16 are photovoltaic panel support columns, which are arranged in a high and low configuration to allow the photovoltaic panels to receive light at an angle, thereby increasing the area for sunlight absorption.
[0017] 4 is the photovoltaic panel tilt angle positioning slider, 3 and 15 are photovoltaic panel tilt angle positioning pins, and 4 is the positioning pin fixing nut. The operation method is to loosen the positioning pin nut, at which point the positioning pin can be inserted and removed. The photovoltaic panel bracket support column (1 and 16) can then be moved by the photovoltaic panel tilt angle positioning slider to adjust the tilt angle of the photovoltaic panel, thereby matching the light angle and increasing the light-receiving area of the photovoltaic panel.
[0018] 11 is the photovoltaic panel support diagonal brace, and 10 is the photovoltaic panel support diagonal brace base. Due to the height of the roof, it is easily affected by extreme weather such as strong winds. By adding 10 and 11, the stress points of the photovoltaic panel are distributed to improve the support stability of the photovoltaic panel.
[0019] 6 is the diagonal brace of the photovoltaic panel bracket, 7 is the horizontal brace of the photovoltaic panel bracket, 12 is the photovoltaic panel, 14 is the base on the back of the photovoltaic panel, 13 is the edge protector of the photovoltaic panel, 2 is the fixing bolt for the diagonal brace and the horizontal brace of the bracket, 8 is the photovoltaic panel positioning guide rail, and 9 is the photovoltaic panel positioning bolt. The highlight of this design is the addition of the photovoltaic panel positioning guide rail (8). When the photovoltaic panel needs to be disassembled, the photovoltaic panel positioning bolt (9) can be loosened, and the photovoltaic panel can be removed or installed along the guide rail. The presence of the guide rail facilitates better positioning and installation of the photovoltaic panel, and also serves as a support.
[0020] By spraying a fluorocarbon coating, a dense protective film is formed through the synergistic effect, which can withstand salt spray corrosion for more than 3,000 hours, which is 3 times that of ordinary galvanized brackets (about 1,000 hours).
[0021] When the coating is damaged, the fluorocarbon coating components can generate oxides to slow down the spread of rust and extend the service life to more than 30 years.
[0022] The recycled carbon fiber support has a specific strength of 3GPa and weighs only 1 / 5 of steel, making it suitable for roofs and complex terrains.
[0023] It can be bent to fit curved roofs or rugged ground, and the tilt angle can be flexibly adjusted to optimize light efficiency. It has a wind pressure resistance of up to 2.0kN / ㎡, and its stability is enhanced by multi-point fixing. It is compatible with various roof types such as corrugated steel sheets and concrete.
[0024] This photovoltaic support structure design utilizes recycled carbon fiber, fluorocarbon coating, and a flexible structure to achieve breakthroughs in corrosion resistance, lightweighting, and scenario adaptability. Furthermore, it reduces overall costs through modular and intelligent design. This will further promote the efficient and low-carbon development of photovoltaic systems.
