Ice breaking and wave absorbing device for offshore wind turbine pile foundation

Abstract

The invention provides an ice breaking and wave absorbing device for an offshore wind turbine pile foundation. The ice breaking and wave absorbing device comprises a plurality of special-shaped structures fixed on the surface of an original pile foundation, each special-shaped structure comprises an upper part and a lower part, the upper part comprises two triangular plates which are arranged in abilateral symmetry mode, the edges A of the triangular plates are attached to and fixedly connected with the surface of the pile type foundation, the edges B of the triangular plates are perpendicular to the axis of the pile type foundation, the plane where the triangular plates are located obliquely intersects with the tangent plane, at the edges A, of the pile type foundation, and the edges C of the two triangular plates on the upper part coincide; and the upper part and the lower part are of a symmetrical structure with the horizontal plane where the edge B is located as the symmetrical plane. A plurality of wave absorbing holes distributed in an array mode are formed in each triangular plate. According to the ice breaking and wave absorbing device, the formation of local continuous ice pressure in the action process of sea ice and the pile foundation can be effectively avoided, and the wave absorbing holes can carry out wave absorbing treatment on waves from all directions, so that the impact load of the waves on the foundation is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of offshore wind power engineering, in particular to an ice-breaking wave-suppression device that can be used for pile foundations of offshore wind turbines. Background technique [0002] With the increasing severity of global warming and environmental pollution, the development and utilization of renewable energy has become a hot topic in energy development around the world. Offshore wind power has the advantages of rich resources, stable wind speed, and continuous regeneration. It has always been concerned and vigorously developed. Wind power can solve the shortage of power supply in some areas and accelerate the development of clean and low-carbon energy transformation in various countries. However, while wind turbines utilize huge wind energy, they must also bear wave impact loads from different sea conditions. In cold winter, the foundation of wind turbines must also bear the threat of a large area of ​...

AI Technical Summary

Problems solved by technology

However, the existing ice-breaking cones are heavy in structure and poor in economy; the inclination angle of the ice-breaking cones is consistent, the climbing direction of the ice surface is single, and sea ice is easy to accumulate; and the surface area of ​​the cone is relatively large. The contact area between waves and currents will increase the wave load on the foundation of the wind turbine and threaten the safety of the wind turbine.
