This invention proposes a floating photovoltaic platform, comprising a photovoltaic support platform, a flexible membrane, and several floats. The photovoltaic support platform includes buoys floating on the water surface and a deck positioned above the buoys. The buoys provide buoyancy, and the deck is used to mount photovoltaic modules. The floats are fixed around the photovoltaic support platform by mooring lines connected to the seabed and are spaced apart from the platform. The flexible membrane connects the deck and the floats, surrounding the photovoltaic support platform. This invention can buffer wave energy in advance using the flexible membrane, while simultaneously guiding water flow to cool the photovoltaic modules, thereby improving photovoltaic power generation efficiency.

A zinc-based high-strength outer sheet with excellent formability and equipped with a GI or ZM coating, and its manufacturing method, are disclosed. The chemical composition of the steel, by mass percentage, is as follows: C: 0.04%–0.1%, Si: 0.2%–0.5%, Mn: 1.2%–1.8%, P≤0.02%, S≤0.01%, Al: 0.02%–0.05%, Cr≤0.5%, Nb≤0.02%, N≤0.006%, with the balance being Fe and unavoidable impurities. The content of Si, Mn, and Cr satisfies the condition: (Mn+Cr)−2×Si≥0.5%. This method, through optimized composition design and precise control of the annealing-galvanizing process, synergistically solves the core contradiction of achieving high strength, high formability, and high surface quality in high-strength outer sheets. In particular, it effectively inhibits surface oxidation of the substrate, ensuring the uniformity, density, and adhesion of the coating, and can stably produce high-quality outer sheet products suitable for pure zinc (GI) and zinc-aluminum-magnesium (ZM) coatings.
