Offshore wind power foundation with scouring monitoring function

Abstract

The invention discloses an offshore wind power foundation with a scouring monitoring function. The offshore wind power foundation with the scouring monitoring function comprises a pile foundation, a scouring monitoring device and an analysis device, wherein the pile foundation comprises a first part and a second part which are connected to each other in the length direction of the pile foundation, the first part is located above the sea level, the second part is located below the sea level and is at least partially embedded in the seabed, the scouring monitoring device is arranged on the peripheral face of the pile foundation and comprises a light sensing assembly and a signal transmitter, the light sensing assembly is arranged on the second part, the signal emitter is used for receiving the light change and sending out a monitoring signal, and the analysis device is electrically connected to the scouring monitoring device so as to be used for receiving and analyzing the monitoring signal sent out by the scouring monitoring device and judging the scouring state of the current pile foundation according to the monitoring signal. The offshore wind power foundation with the scouring monitoring function has the advantages of being capable of monitoring at any time, simple and effective.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to an offshore wind power foundation with a scour monitoring function. 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. [0003] The offshore wind power foundation with scour monitoring function is the key to supporting the entire offshore wind turbine, and the cost accounts for about 20% to 25% of the entire offshore wind power investment, and the accidents of offshore wind turbines are mostly caused by unstable pile foundations. Due to the action of waves and tidal currents, the sediment around the offshore wind power pile foundation will be scoured and form scour ...

AI Technical Summary

Problems solved by technology

In addition, the water flow mixed with sediment near the seabed surface continuously scours the pile foundation, corrodes and damages the surface of the pile foundation, and in severe cases, it will cause the collapse of the offshore wind turbine unit

However, the offshore wind power pile foundations are all buried in the seabed, and the erosion cannot be directly observed. When the erosion is serious, the pile foundation cannot be maintained in advance.
