[0002] Due to the complex conditions at sea, including the effects of waves, currents, and ice, traditional support systems have significant drawbacks in the harsh marine environment. Traditional systems rely on pile foundations, and uneven seabed geology can lead to differential settlement of the piles, causing deformation of the superstructure and even stress exceeding limits and cracking of the photovoltaic module frames. Traditional solutions also require offshore welding operations, resulting in low construction efficiency, long construction periods, and difficulties in transporting large-span platforms at sea, leading to high costs. Furthermore, offshore construction is challenging and requires sophisticated transportation equipment. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a monopile offshore photovoltaic support structure that can solve the problems of deformation of the superstructure caused by differential settlement of pile foundations due to the use of group pile foundations in traditional offshore photovoltaic supports, as well as the problem of low efficiency of offshore welding construction.

The upper photovoltaic structure can be prefabricated on shore. The upper photovoltaic structure includes several lower inclined braces, several upper inclined braces, several transverse struts, several inclined beams, and several purlins. The lower inclined braces form a spatial truss support structure. The upper and lower inclined braces are connected by the transverse struts to form an interlaced rigid grid structure.
