Anti-scouring offshore wind power single pile foundation device

Abstract

The invention discloses an anti-scouring offshore wind power single pile foundation device. The anti-scouring offshore wind power single pile foundation device is characterized in that protection disc devices are fixed on a pile foundation; the lower end of the pile foundation is fixed at the bottom of a seabed; the protection disc devices are fixed on the pile foundation, and the protection disc devices are located below the sea level; a wind power main machine and a wind power tower drum are sequentially installed on the single-pile foundation; a protection layer is formed on the outer side of the pile foundation 3 through the protection disc devices, impact is formed on the periphery of the pile foundation when seawater washes the pile foundation, and under the blocking effect of the protection disc devices, formation and transmission of a diving vortex structure, a horseshoe-shaped vortex structure and a wake vortex structure are effectively limited; the winding and digging effect of diving vortexes on the seabed surface can be effectively blocked, wherein a plurality of protection disc devices are mounted on the pile foundation and are horizontally arranged; a multi-layer protection layer structure is formed by the plurality of horizontally arranged protection disc devices, the stability of the protection disc devices is improved, and meanwhile, the winding and digging effect of blocking diving vortexes on the seabed surface can be improved by the plurality of horizontally arranged protection disc devices.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to an offshore wind power monopile foundation device for preventing erosion. Background technique [0002] As a clean and harmless renewable energy, wind energy has been paid more and more attention by human beings. Among them, compared with land wind energy, offshore wind energy resources not only have higher wind speeds, but also are farther away from the coastline, and are not affected by noise limits, allowing larger unit manufacturing. The foundation cost of offshore wind turbines accounts for about 20% to 25% of the entire offshore wind power investment. The single pile foundation has been widely used in shallow sea areas (water depth <30m) due to its simple manufacture and convenient construction. [0003] The offshore wind power monopile foundation is a long cantilever structure device. The bottom of the foundation goes deep into the shallow overburden + bedrock seabed...

Problems solved by technology

The connection between sandbags or between stones is usually very weak, and it is difficult to form a complete whole. When the current velocity is large, it is easy to be washed away, and it is difficult to play a protective role
