Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic support for deserts with a wind and sand protection structure. Background Technology

[0002] Photovoltaic power generation is a power generation technology that directly converts sunlight into electrical energy. Its core principle is called the photovoltaic effect. It includes photovoltaic modules, photovoltaic brackets, inverters and auxiliary components. Among them, photovoltaic brackets are used to fix photovoltaic panels. There are many types of photovoltaic brackets, including fixed brackets and tracking brackets. To this end, patent CN221728204U discloses a photovoltaic module support for desert photovoltaic applications, including a base. Hollow tubes are symmetrically fixedly connected to the upper surface of the base. Support blocks are slidably connected to the inner walls of two hollow tubes. One end of each support block extends out of the corresponding hollow tube and is rotatably connected to a photovoltaic support. A photovoltaic panel body is fixedly connected to the inner wall of the photovoltaic support. A sliding groove is formed through the upper surface of the base. A slider is slidably connected to the inner wall of the groove. One end of the slider extends out of the groove and is rotatably connected to a support block. A stop block is rotatably connected to the outer wall of one end of the support block, and the other end of the stop block is rotatably connected to the base. A half-gear is fixedly connected to the lower surface of the photovoltaic support. Gear rings are symmetrically fixedly connected to the outer wall of the support block. This design adjusts the angle between the photovoltaic support and the photovoltaic panel while reducing the height of the photovoltaic support, thus avoiding unnecessary damage to the photovoltaic panel during severe weather. Existing desert photovoltaic (PV) mounting systems are ineffective at preventing sandstorms. Sand accumulates on the PV modules, affecting power generation efficiency. At the same time, sandstorms also impact the PV mounting systems, causing damage. Utility Model Content
