Integrated multidirectional loading model test device for offshore wind turbines

An integrated multidirectional loading model test device for offshore wind turbines, comprising:

• a water flume,
• a wave-making mechanism provided at a first end of the water flume,
• a top hood provided at a top of the water flume to form an air duct, a first end of the top hood being formed as an air inlet end and a fan is being provided at a second end of the top hood,
• a seabed soil holding sink provided at a set position at a bottom of the water flume,
• a rotating disk provided at a bottom of an interior of the seabed soil holding sink,
• a model barrel for placing seabed soil and an offshore wind turbine model being fixed on the rotating disk, and
• the rotating disk being connected to a driving mechanism to drive the model barrel to rotate, so that a relative motion between the model barrel and the fixed water flume can be generated to achieve an application of wind and wave loads in different directions to the offshore wind turbine model;
• wherein (i) both the seabed soil holding sink and the model barrel are of cylindrical structure, and a gap between an outer side of the model barrel and an inner side of the seabed soil holding sink is less than a set value, or (ii) the outer side of the model barrel slides against the inner side of the seabed soil holding sink, or (iii) the outer side of the model barrel is provided with a sealing ring against the inner side of the seabed soil holding sink;
• and
• wherein the driving mechanism comprises a driving component, the driving component is connected to a connecting rod via a transmission mechanism, a first end of the connecting rod is fixedly connected to the rotating disk, and a second end of the connecting rod is rotatably connected to a tank wall of the bottom of the seabed soil holding sink.
