Description

Technical Field

[0001] This invention belongs to the field of solar photovoltaic power generation technology, and particularly relates to an adjustable support fixture for assembling offshore photovoltaic steel grid structures. Background Technology

[0002] Offshore photovoltaic (PV) power generation is an emerging clean energy development model. By transferring PV power plants from land to the ocean surface, it fully utilizes the advantages of the open, unobstructed sea surface, long hours of sunshine, and high solar radiation, significantly improving power generation efficiency. Compared with onshore PV, offshore PV projects face a more complex engineering environment, requiring comprehensive consideration of multiple factors such as meteorological and hydrological conditions, geological conditions, and structural safety, which places higher demands on the stability and adaptability of the PV support system.

[0003] In existing technologies, offshore photovoltaic (PV) support structures mainly adopt large-span steel grid structures. To ensure the accuracy of ground assembly, a specialized support tooling system is required during construction. These support tools are typically fixed on the ground and use rigid support points to position and temporarily fix the steel grid units, ensuring the geometric accuracy and node connection accuracy of multi-span continuous steel grid units during assembly, thus creating conditions for subsequent overall hoisting.

[0004] However, the existing support fixtures are designed with a fixed height, which cannot be dynamically adjusted according to the height changes required during the steel space frame assembly process. On the one hand, this results in a lack of effective real-time correction methods when height deviations occur during the steel space frame assembly, which may cause cumulative errors and affect the overall installation accuracy. On the other hand, the fixed support height is difficult to adapt to changes in tide level and wave impact, which increases the risk of structural stress concentration and directly affects construction safety and the lifespan of the support system.
