Description

Technical Field

[0001] The utility model belongs to the technical field of solar energy installation, and in particular relates to a quick fixing device for a flexible bracket of a photovoltaic panel. Background Art

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. They are mainly composed of photovoltaic cells, which are usually made of semiconductor materials (such as silicon). The working principle of photovoltaic panels is based on the photovoltaic effect, that is, when photons hit the atoms of semiconductor materials, they stimulate the flow of electrons, thereby generating electric current. This current can be used directly for power supply, or converted into alternating current for home or industrial use through an inverter. The materials of photovoltaic panels include glass, EVA (ethylene-vinyl acetate copolymer) and TPT (polyvinyl fluoride film), etc. These materials have good light transmittance and anti-aging ability, which can ensure that photovoltaic panels maintain high efficiency during long-term use. There are various types of photovoltaic panels, including monocrystalline silicon and polycrystalline silicon photovoltaic panels, as well as modules of different powers and sizes, suitable for different application scenarios, such as large ground power stations, industrial and commercial roofs, and residential roofs. High-performance photovoltaic modules have the characteristics of high conversion efficiency, high bifaciality, low temperature coefficient and low attenuation, which can significantly improve power generation and reliability.

[0003] Photovoltaic panels need to be installed on solar brackets. The unique design structure of solar brackets allows the components to be adjusted according to different regions, so that local solar energy resources can be fully utilized to achieve the maximum power generation efficiency of solar components. At the same time, the connection method, material selection and bracket load force analysis of photovoltaic components are analyzed and practiced in detail, so that they have good physical properties such as earthquake resistance, wind resistance, snow pressure resistance and corrosion resistance, so that photovoltaic components can be used in a wider range of regions. Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy and stainless steel. Photovoltaic bracket products are divided into ground type, roof type, wall type, portable type, etc. Existing solar brackets are suitable for installation on fixed planes, and most of them are fixed on the ground or roof, and support frames need to be set at intervals. This type of solar bracket requires the erection of a large number of support frames, and has high requirements for the ground, such as the need to occupy a flat ground, the height of the erection is limited, and the space under the photovoltaic panel cannot be reused, and the overall cost is high. In order to reduce operating costs and improve the application scenarios of photovoltaic panels, such as lakes and aquaculture farms, these places can have more available resources relative to limited land resources and have less impact on their environmental factors. For example, above aquaculture farms, it can also serve as a sunshade and rain shelter; large-span connections can be achieved by using cables, and quick installation can be achieved, but cables are prone to shaking, which is not conducive to high-altitude operations, and shaking during use can easily cause cracks and damage to photovoltaic panels; and the existing photovoltaic panel clamping and fixing devices are directly fixed to the photovoltaic panels with bolts, with a small operating space, which is not conducive to engineering assembly, and has high material and construction costs.
