Abstract

The invention discloses a supporting structure of a fixed offshore photovoltaic power generation platform and a construction method of the supporting structure. The supporting structure comprises a platform truss, a box foundation, supporting columns, negative pressure pumping holes and a towing float; the box foundation is arranged below the platform truss; the supporting columns connect the platform truss and the box foundation; the supporting columns are of a hollow structure, and the bottoms of the supporting columns communicate with the box foundation; the negative pressure pumping holesare formed in the tops of the stand columns and communicate with the supporting columns; and the towing float is arranged on the box foundation and connected with the supporting columns through connecting cables. According to the supporting structure of the fixed offshore photovoltaic power generation platform and the construction method of the supporting structure, for adopting modular design, each platform supporting structure can be formed separately, the adjacent structures are connected through hinges, the good integrity of the structures is ensured, meanwhile, the huge bending moment bore by the platform truss when the platform truss is laid on a large scale is greatly reduced, and the structures are enabled to have higher ability to resist environmental load.

Description

technical field [0001] The invention relates to offshore structure and photovoltaic power generation structure technology, in particular to a fixed offshore photovoltaic power generation platform support structure and a construction method thereof. 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 generatio...
