Abstract

The invention discloses a wind and wave resisting floating type offshore photovoltaic power generation platform. A platform truss, a photovoltaic plate assembly, weight balls, support columns, a floater, a heaving plate, pile foundations and mooring cables are included. The photovoltaic plate assembly is flatly laid on the platform truss. The weight balls are arranged below the platform truss. Thesupport columns are connected with the platform truss and the weight balls. The floater is fixed between the support columns, and buoyancy provided by the floater can be transmitted to the photovoltaic power generation platform. The heaving plate is connected to the lower portions of the weight balls. The pile foundations are fixed in a seabed and used for mooring the offshore photovoltaic powergeneration platform. One ends of the mooring cables are moored to the support columns, and the other ends of the mooring cables are moored to the pile foundations. By means of the wind and wave resisting floating type offshore photovoltaic power generation platform, the capability of resisting wind, waves and flow loads through a supporting structure is guaranteed, economic feasibility and construction convenience are achieved, and accordingly application of the photovoltaic power generation platform to the field of ocean open water area is assisted.

Description

technical field [0001] The invention relates to offshore structure and photovoltaic power generation structure technology, in particular to a wind and wave-resistant floating offshore photovoltaic power generation platform. Background technique [0002] In recent years, solar photovoltaic power generation has developed rapidly as a green, clean and renewable energy. However, due to the large land area occupied by onshore solar photovoltaic power generation and the scarcity of land resources, the development of onshore solar photovoltaic power stations is greatly restricted. The central desert area, which greatly increases the electricity cost of solar photovoltaic power generation, which also restricts the development of solar photovoltaic power generation. [0003] Aiming at the problem that solar photovoltaic power generation occupies more land resources and is far away from the power consumption center, floating solar photovoltaic power generation can be well solved. In ...
