Background

At present, wave energy and wind energy power generation devices in different forms are vigorously developed, and the wave energy and wind energy power generation devices are widely concerned.

The oscillating water column type wave energy power generation is one of wave energy power generation modes which are widely researched and applied at present, and is an important technical branch for wave energy utilization. The oscillating water column device compresses and sucks air in an air chamber by utilizing the oscillating water column formed by wave fluctuation to generate airflow to drive an air turbine, and then drives a generator to generate electricity. The wind turbine foundation is used as a supporting system of a wind turbine generator and is very important in offshore wind power construction. Offshore wind farms built at home and abroad mainly take the forms of single-pile supporting structures, gravity type supporting structures, tripod supporting structures, jacket supporting structures, bearing platform type supporting structures and the like.
