Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic auxiliary equipment, and specifically discloses a multi-angle wind-resistant device for a photovoltaic component. Background Art

[0002] Photovoltaic panels, one of the primary components for converting solar energy into electricity, are widely used in the construction industry. They not only significantly reduce building energy consumption but also significantly improve a building's energy conservation and environmental performance. PV panels are typically installed on building roofs or on sunny surfaces. They require secure and reliable mounting methods to secure the panels. While various mounting methods exist, incidents of panels falling off the mounting brackets are common, especially in areas prone to strong winds.

[0003] At present, the existing technology uses a metal frame to firmly install the photovoltaic panel in an inclined and hollow frame. The inclined frame is fastened to the base frame by long-rod bolts, and the base frame is fixed to the ground. Since most photovoltaic modules are arranged on a large scale in an area with strong wind and relatively open space, the wind in this area is strong, often reaching gale force 8-10. The frame structure in the existing technology is easily loosened by wind vibration when blown by strong wind for a long time, thereby causing the overall connection structure to vibrate and deform. At the very least, it may cause the photovoltaic module and the installation frame to disintegrate, and at worst, it may easily cause an electrical accident, thus posing a high safety hazard. Utility Model Content
