OFFSHORE WIND TURBINE FOUNDATION, CONSTRUCTION METHOD THEREFOR, ICE-RESISTANT DEVICE AND WIND POWER GENERATION SET

WIPO Patent Application WO/2022/151740

A1

An ice-resistant device for an offshore wind turbine foundation, an offshore wind turbine foundation having the ice-resistant device, a construction method therefor and a wind power generation set using the offshore wind turbine foundation having the ice-resistant device. The ice-resistant device comprises a shell plate (41), toggle plates (42), watertight partition plates (43), an upper ring beam (46) and a lower ring beam (47), wherein the upper ring beam (46) and the lower ring beam (47) are respectively connected to the two ends of the toggle plates (42), the toggle plates (42) are evenly arranged in the circumferential direction of the upper ring beam (46) and the lower ring beam (47), the watertight partition plate (43) is arranged in the middle of the toggle plate (42), the width of the toggle plate (42) is gradually reduced from the center to the two ends, the shell plate (41) is vertically symmetrical with regard to the watertight partition plates (43), the shell plate (41) is connected to the toggle plates (42), the upper ring beam (46) and the lower ring beam (47), the intersection line of the toggle plates (42) and the shell plate (41) is a super-elliptic curve, and the shell plate (41) is curved, so that an impact force of floating ice can be more effectively decomposed into a supporting force perpendicular to the shell plate, and the failure mode of the floating ice changes from compressive failure to bending failure.
