Description

Technical Field

[0001] The utility model relates to a multi-layer offshore photovoltaic support structure. Background Art

[0002] The construction cost of offshore wind power is relatively high, requiring a large amount of capital, manpower and material resources, including wind turbines, transmission lines, foundation laying and other links; in addition, since offshore wind farms are generally built in deep sea areas with larger waves, the transportation and infrastructure costs are higher. Offshore wind power requires frequent maintenance and overhaul during operation, and usually requires shutdown operations.

[0003] Compared with traditional photovoltaic power stations, the construction cost of offshore photovoltaics is higher, including equipment, engineering and maintenance costs. In addition, offshore photovoltaic power stations are easily affected by sea conditions such as wind, waves and currents, and are mostly built on mudflats and offshore areas. For the construction of offshore photovoltaics in deep sea areas, related technologies such as floating offshore photovoltaics are still not mature.

[0004] At present, offshore photovoltaic support structures and photovoltaic panels are mostly spread over a large area along the horizontal space, occupying a large area of ​​sea area. For pile-based fixed offshore photovoltaic support structures, a large number of piles will be driven into the sea to support the upper structure. When the life of the photovoltaic project ends, the recovery of structural components is relatively cumbersome. In addition, due to technical and cost constraints, the current offshore photovoltaics are mostly built on tidal flats and offshore areas. For the construction of offshore photovoltaics in deep and deep sea areas, related technologies such as floating offshore photovoltaics are not yet mature. Therefore, a multi-layer offshore photovoltaic support structure is proposed to address the above problems. Utility Model Content
