This invention belongs to the field of
tidal power generation technology and relates to a multi-degree-of-freedom adaptive motion compensation device for connecting a floating
turbine and a carrier. The device includes a carrier and a
turbine, with a retractable hydraulic rod
assembly, a turntable, and a slide rail arranged sequentially between them. The retractable hydraulic rod
assembly consists of three retractable hydraulic rods arranged in an equilateral triangle. The length of the retractable hydraulic rods is adjustable. One end of each retractable hydraulic rod is connected to the semi-submersible carrier, and the other end is connected to the turntable. The turntable consists of an upper and lower part and can rotate 360 degrees. The slide rail includes a slide path and a slider. The slider is connected to the bottom of the turntable and drives the turntable to slide along the slide rail. This invention improves and optimizes the mechanical connection structure between the
turbine and the carrier to eliminate or reduce the swaying motion of the turbine caused by
waves, thereby improving the stability and efficiency of the turbine operation, extending the service life of the turbine, and enhancing the applicability of the turbine unit under different sea conditions.
