AI Technical Summary

Technical Problem

Existing offshore wind power foundations are prone to scour pits under the action of waves and currents, which reduces the stability of the pile foundation. Existing protective measures cannot effectively suppress the formation of eddies and provide timely warnings, and the construction costs are high and maintenance is frequent.

Method used

The system employs a flow-disrupting mechanism in conjunction with an adjustment mechanism to precisely disrupt the incoming flow and prevent the formation of horseshoe vortices. It also uses a detection mechanism and an expandable rubber airbag to fill the scour pit, enabling early warning and protection against scour pits.

Benefits of technology

It effectively suppressed the formation of horseshoe vortices, improved the stability of the pile foundation, reduced seabed scouring, enabled timely early warning and protection of scouring pits, and reduced construction and maintenance costs.

Abstract

The application relates to the technical field of offshore wind power foundations, and discloses a high-stability offshore wind power foundation, which comprises a pile foundation, the outer side of the pile foundation is surrounded by a protective insertion cylinder, the top surface of the protective insertion cylinder is horizontally extended outward to form a horizontally extended skirt plate, a plurality of rubber air bags are arranged below the horizontally extended skirt plate, an expansion mechanism is arranged on the rubber air bags, a monitoring mechanism is arranged on the outer side of the protective insertion cylinder, an annular transition bin is rotatably arranged on the circumferential outer side of the protective insertion cylinder, a flow disturbing mechanism and an adjusting mechanism are arranged on the annular transition bin, and a plurality of electromagnetic current meters are mounted on the outer side of the pile foundation through mounting racks. The flow disturbing mechanism cooperates with the adjusting mechanism to accurately and effectively disturb the incoming flow, the horseshoe vortex is prevented from being formed, and the stability of the whole pile foundation is improved. Meanwhile, the inflatable rubber air bags are arranged, the inflatable rubber air bags can fill the scour pits after being inflated, automatic protection measures can be taken after the scour pits are warned, and the stability of the whole pile foundation is further improved.
