Offshore wind power pile foundation and stability monitoring method thereof

Abstract

The invention provides an offshore wind power pile foundation and a stability monitoring method thereof. A base is poured at the lower end of a pile foundation main body, a monitoring ring is arranged outside the pile foundation main body in a sleeving mode, and a driving mechanism used for driving the monitoring ring is arranged outside the pile foundation main body. The stability monitoring method comprises the steps that the monitoring ring is moved up and down through the driving mechanism, a main body monitoring mechanism and a base monitoring mechanism on the monitoring ring monitor the pile foundation main body and the base correspondingly, the fluctuation distance is monitored through a distance sensor, and thus the size of a pit is judged to judge whether the wind power pile foundation is affected or not. The monitoring effect on the wind power pile foundation is good, thus timely maintenance is achieved, and loss is avoided.

Description

technical field [0001] The invention relates to the technical field of wind power pile foundation and monitoring thereof, in particular to an offshore wind power pile foundation and a stability monitoring method thereof. Background technique [0002] With the continuous growth of domestic demand for energy, non-renewable resources such as oil are facing a trend of depletion, and renewable energy has attracted more and more attention and attention. As a new type of pollution-free and clean industry, offshore wind farms have begun to be established in my country, and offshore wind power technology has begun to be widely used. The tidal current energy, which is also rich in reserves and widely distributed, is also favored by various countries. It has great development prospects and commercial value. The installed capacity of offshore wind turbines in my country is also increasing year by year. Since both power generation devices are located in the ocean, combining offshore win...

Problems solved by technology

[0003] After the completion of offshore wind turbines, with the passage of time, under the action of the erosion of waves and currents, potholes will be formed in the wind power pile foundation and foundation. When the pothole is large, it is easy to cause the wind turbine to tilt or even collapse, and maintenance requires a lot of manpower, material resources and time. For this reason, there is an urgent need for a wind power pile foundation suitable for the harsh offshore environment, as well as a pair of wind turbines.
