Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation civil engineering structures, in particular to a reinforced and transformed photovoltaic support structure. Background Art

[0002] New energy photovoltaic power generation equipment typically consists of 26 or more photovoltaic modules connected as a string and mounted on a photovoltaic rack. The rack features a diagonal beam, typically made of thin-walled rolled-edge channel steel. Purlins, typically thin-walled rolled-edge channel steel, are mounted on the top surface of the diagonal beam, spaced 1.4 meters apart based on the module mounting bolt hole spacing. The photovoltaic module frame is bolted to the top of the purlin.

[0003] The design life of a photovoltaic power station is generally 25 years. The first batch of grid-connected PV plants are nearing the end of their design lifespan, and the performance of their PV modules has significantly degraded. To maximize investment savings, existing PV mounting systems should be reused whenever possible. To ensure that existing mounting systems meet the installation requirements of current mainstream modules, the mounting structures must be reinforced.

[0004] When renovating a photovoltaic power station that has reached the end of its service life, it is necessary to use current mainstream components to replace old components whose working performance has been greatly reduced. Compared with old components, new components generally have higher conversion efficiency and larger dimensions, and the bolt hole spacing for component installation is also different. The original photovoltaic brackets do not meet the installation requirements of the new components in terms of load-bearing capacity and structure. Utility Model Content
