Description

Technical Field

[0001] The utility model relates to the technical field of steel frames, in particular to a component steel frame for a solar photovoltaic power station. Background Art

[0002] Energy conservation and emission reduction have become more and more important. The traditional photovoltaic module frame material is aluminum alloy. However, the electrolytic aluminum is a high-energy consumption link in the aluminum alloy production process. The electricity consumption of electrolyzing one ton of aluminum is about 13,500 kWh, while the electricity consumption of producing one ton of steel is only 4,500 kWh. Therefore, in terms of energy consumption, steel is only 1 / 3 of aluminum alloy, and in terms of carbon emissions, steel is far lower than aluminum alloy. As the price of aluminum continues to rise, the cost of aluminum alloy frames has increased, while the price increase of steel is lower than that of aluminum. Based on the above background, photovoltaic module steel frames with zinc-aluminum-magnesium coating came into being.

[0003] The steel frame of photovoltaic modules is made of zinc-aluminum-magnesium coated steel, which has the advantages of high strength, good corrosion resistance, and self-repair of cross-section. Aluminum alloy frames are mostly made of 6005-T5, with a yield strength of 240N / mm2. The yield strength of zinc-aluminum-magnesium steel frames is 450N / mm2, which is much stronger than aluminum alloy frames.

[0004] The existing steel frames for solar photovoltaic power station components involve three parts: the long side of the steel frame, the short side of the steel frame, and the corner bracket. The connection between the traditional steel frame and the corner bracket mainly relies on the friction between the teeth on the corner bracket and the steel frame. This structure can withstand less pulling force and will damage the anodized layer on the inner wall of the steel frame when pulled. Utility Model Content
