Offshore wind turbine tower multi-point rigid connection base platform device

Abstract

This invention discloses a base platform device for multi-point rigid connection of offshore wind turbine towers, specifically relating to the field of tower installation technology. It includes a base on which a support assembly is mounted. The support assembly comprises a pad on top of the base, a reinforcing toothed ring above the pad, a crossbar on top of the reinforcing toothed ring, and a standard section on top of the crossbar. This invention forms multiple rigid connection points by setting bidirectional spools, traction heads, hinge seats, and positioning plates at the four corners of the standard section. Compared to traditional single-point or two-point connection methods, this structure can distribute the bending moment, shear force, and axial force borne by the bottom of the tower to multiple nodes, reducing the stress level at individual connection points and avoiding localized stress concentration. Simultaneously, the multi-point coordinated constraint effectively limits the lateral displacement and torsional deformation of the tower under the influence of wind, waves, and currents, improving the wind and vibration resistance of the entire unit during high-altitude operations and ensuring structural stability and reliability.
