The application relates to the technical field of computer-aided engineering and computer-aided design data integration, and discloses a Catia data conversion method and system for CAE preprocessing modeling software, which comprises the following steps: loading a Catia model and traversing a product structure tree to extract parameterized semantic information; converting geometric data into a boundary representation format and detecting defects; automatically repairing serious topological defects by using a deep learning model; constructing a hierarchical intermediate format based on a general digital thread protocol, and associating geometry, semantics and analysis attributes; dynamically adjusting model precision according to simulation types; and exporting a format suitable for CAE software and generating a parameter mapping table. The application can realize lossless conversion of a Catia model to a CAE environment, retain design semantics and parameter association, support precision self-adaptive adjustment of multi-physical field analysis, and significantly improve CAE preprocessing efficiency.

The utility model discloses a photovoltaic device. The photovoltaic device comprises a photovoltaic assembly and an installation frame. The photovoltaic module comprises a photovoltaic panel and a mounting piece which are connected; the installation frame comprises a guide part, a sliding groove is formed in one of the guide part and the installation part, a sliding part is formed in the other one of the guide part and the installation part, the sliding part is arranged in the sliding groove and matched with the sliding groove, and the installation frame is used for installing the photovoltaic module so that the photovoltaic panel can be vertically arranged. When the photovoltaic module is installed, the sliding piece is pushed into the sliding groove in the extending direction of the sliding piece, installation is convenient, installation holes do not need to be formed in the installation frame and the installation piece, and therefore the machining cost of the installation frame and the installation piece can be reduced. Meanwhile, the installation frame is used for installing the photovoltaic module so that the photovoltaic panel can be vertically arranged, and therefore the photovoltaic device is small in occupied area and can be widely applied to photovoltaic power generation in densely populated areas.
