Description

Technical Field

[0001] This utility model relates to an assembly and support fixture for a large offshore photovoltaic platform. Background Technology

[0002] Offshore photovoltaic (PV) systems are solar photovoltaic power generation systems constructed in nearshore, tidal flat, and other marine environments. They effectively utilize vast marine resources, reduce the occupation of land resources, and minimize environmental impact. Currently, the main structures of offshore PV systems are either floating or pile-based. A offshore PV project in Shandong Province uses a pile-based structure. A typical offshore PV system consists of a PV platform and four piles driven into the sea. The PV platform is a truss structure with dimensions of 60m × 33.7m × 2.5m (length × width × height). PV panels are installed on the top surface of the platform. The upper structure of the PV platform (excluding the four legs) is assembled from seventeen truss sections. These seventeen truss sections are first manufactured as semi-finished products by a steel structure fabrication plant and then transported by truck to the assembly base at the dock for assembly. After assembly, the PV panels require precise positioning and installation; therefore, the precision requirements for assembling the seventeen truss sections are extremely high. During the assembly process, the truss pieces need to be precisely measured and positioned, and the position and elevation of the support fixtures need to be adjusted simultaneously. Therefore, it is urgent to design a lightweight, easy-to-install and disassemble, height-adjustable assembly support fixture. Utility Model Content
