Self-maintenance anti-washing device of offshore wind power pile foundation

Abstract

The invention provides a self-maintenance anti-washing device of an offshore wind power pile foundation. The self-maintenance anti-washing device comprises the pile foundation, an isolation barrel, anouter supporting frame assembly and an isolation shade assembly. The pile foundation is mounted at the upper end of a seabed. The outer side of the pile foundation is connected with the isolation barrel in a sleeved manner. The bottom of the isolation barrel is fixed to the upper end of the seabed. The outer side of the isolation barrel is fixedly connected with the outer supporting frame assembly. Drive assemblies are mounted at the positions, corresponding to pushing assemblies, of the outer side of the isolation barrel. First grooves are vertically arranged at the positions, located on thedrive assemblies, of the outer side of the isolation barrel. First rack rods are vertically arranged at the positions, corresponding to the first grooves, of the outer side of the isolation barrel. Arepair device is mounted at the upper end of the pile foundation. A second rack rod is vertically and fixedly connected to the inner side of the isolation barrel. The repair device and the second rack rod are in transmission connection. According to the self-maintenance anti-washing device of the offshore wind power pile foundation, the problems that existing offshore wind power pile foundationsare prone to being washed and corroded by sea water, the pile foundations are not stable, workers need to maintain the pile foundations frequently, time and labor are wasted, meanwhile, the anti-washing effect is poor, silt beside the pile foundations cannot be blocked, and the situation that concave pits are formed by washing cannot be avoided are solved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power pile foundation protection, in particular to a self-maintenance anti-scouring device for offshore wind power pile foundations. Background technique [0002] According to the latest data, offshore wind power generation is a clean and environmentally friendly power generation method, and all countries are vigorously promoting it. Wind power generation is second only to hydropower generation and accounts for 16% of the global renewable resource power generation. my country's offshore wind power installed capacity is also growing year by year; in the context of the global focus on the development of a low-carbon economy, offshore wind power has the potential to become an indispensable renewable energy power in the path of sustainable development; in densely populated coastal areas, it can be quickly established Gigawatt-level offshore wind farms also make offshore wind power one of the most ...

AI Technical Summary

Problems solved by technology

[0003] The offshore wind power pile foundation is the key to supporting the entire offshore wind turbine, and the cost is about 14% of the entire offshore wind power generation device. Due to the influence of current and tide, the sediment around the offshore wind power pile foundation will be scoured and form a scour pit, which will affect the stability of the pile foundation; in addition, the water flow mixed with sediment near the seabed surface is constantly The pile foundation is scoured, and the surface of the pile foundation is damaged by corrosion. In severe cases, it will cause the collapse of the offshore wind turbine unit. Therefore, a self-maintenance and anti-scouring device for offshore wind power pile foundations is proposed.
