Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, specifically relating to a prestress observation and adjustment device for flexible photovoltaic support. Background Technology

[0002] In the field of photovoltaic power generation technology, flexible photovoltaic (PV) supports are characterized by large spans, high clearance, and high utilization of the underlying space, making them widely used in mountainous areas, fishponds, tidal flats, and sewage treatment plants. The flexible PV support structure uses prestressed steel cables tensioned between two fixed points, utilizing the large deformation of the prestressed steel cables to resist the weight of the PV modules, wind, snow, and maintenance loads.

[0003] The internal forces of flexible photovoltaic (PV) support cables have a significant impact on the safety and stability of the support system. Therefore, strict limits on cable internal forces are necessary during the design phase, and it must be ensured that the internal forces do not change significantly throughout the entire operational phase. During long-term operation, factors such as temperature variations, support deformation, and creep of the side anchors can directly lead to cable slack or tension. Cable slack results in a decrease in internal forces, reducing the rigidity of the support system and increasing deformation under gravity or wind and snow forces, thus affecting structural safety. Cable tension increases internal forces, increasing the tensile force on the side anchors or directly, and in severe cases, can directly cause structural collapse.

[0004] In existing technologies, it is difficult to visually observe changes in cable slack or tension; only periodic manual checks using specialized equipment are possible. This method requires complex and expensive equipment, and it cannot provide real-time monitoring to determine whether the cable's internal forces meet safety requirements. Utility Model Content
