Abstract
The invention discloses a hole-opened spherical shell-shaped ship collision prevention device of an offshore wind turbine. The hole-opened spherical shell-shaped ship collision prevention device comprises an offshore wind turbine structure and a spherical shell-shaped ship collision prevention device combined structure, wherein the spherical shell-shaped ship collision prevention device combined structure comprises a spherical shell-shaped thin-wall steel plate structure installed at a waterline part of a single-pile foundation in a sleeving manner, as well as a soft rubber isolation cushion structure and an annular support steel plate structure which are fixed on the spherical shell-shaped thin-wall steel plate structure, and the front end of the soft rubber isolation cushion structure is arranged in a groove of the annular support steel plate structure. The hole-opened spherical shell-shaped ship collision prevention device has the following beneficial effects: a hole-opening design of the spherical shell-shaped thin-wall steel plate structure is capable of effectively reducing a wave load and better dissipating ship collision energy by virtue of the own plastic deformation of a thin steel plate; the soft rubber isolation cushion structure is capable of effectively reducing a ship collision force transferred to a tower structure, and generates rotation movement in the case of collision to guide a ship to deviate from a main body structure of the wind turbine, thus reducing collision damage; and the device is reasonable in structural design, convenient to construct, and free from influence on the original structural design of a wind turbine.
