Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and more specifically, to a mounting bracket for a photovoltaic power station. Background Art

[0002] Photovoltaic power stations use the photovoltaic effect to directly convert solar energy into electrical energy through photovoltaic panels. The photovoltaic cells on the photovoltaic panels absorb photons in sunlight and convert them into electron flows, thereby generating direct current, which is then converted into alternating current through an inverter for use in the power grid or electrical equipment. The photovoltaic panels of photovoltaic power stations are usually installed on brackets or supporting structures on the ground.

[0003] The existing concrete piles and photovoltaic brackets are usually connected by bolts, and there is usually a lack of waterproof protection structure between the photovoltaic bracket and the concrete piles, resulting in the connection between the concrete piles and the photovoltaic bracket being exposed for a long time. If the surrounding environment is relatively humid, the photovoltaic bracket will cause rust and damage. In particular, when the bracket is in an area with heavy rain, the erosion of rainwater will greatly accelerate the rust and damage of the connector, which will not only increase the workload of maintenance personnel and increase the cost of use and maintenance, but may also cause the connection to loosen and break, causing damage to the bracket and the solar photovoltaic panel, posing certain safety hazards. At the same time, some existing brackets are fixedly connected to the support plate of the photovoltaic panel, which is not convenient for adjusting and fixing the elevation angle of the support plate, which can easily affect the ability of the photovoltaic panel to absorb solar radiation, thereby reducing the power generation efficiency.
