Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic construction, and particularly refers to a construction platform for an offshore photovoltaic support. Background Art

[0002] Offshore photovoltaic is a key carrier for the integration of energy transformation and marine economy, which can effectively alleviate the problem of land shortage faced by onshore photovoltaic by utilizing marine space. In order to install photovoltaic on the sea, a construction platform needs to be set up on the sea, and construction workers stand on the construction platform to install the photovoltaic support on the photovoltaic pile foundation.
