The device comprises a wave simulating device, a motor, a braking device, a controller device and a terminal control device, wherein the wave simulating device comprises buoy carrying platforms, a swing mechanism, a north half ring shaft, a double-ring truss mechanism and a south half ring shaft. The device can be used for vividly simulating movement tracks of the wave buoy on a sea surface, and ensures that the wave buoy can swing on the basis of a translational motion, with regulated swing angle, when rotating along with the calibrating device, so that the sine characteristic movements of waves are accurately simulated, and the wave height and the wave period of the wave buoy are accurately measured and calibrated; and after the wave buoy is clamped once, the wave buoy can be transferred to a next detection point without being detached. The device is capable of calibrating the wave buoy within a wave height range of 2m to 10m and a wave period range of 3.7s to 60s. The rotating direction of the device is changeable, so that the device can be used for correspondingly simulating two opposite wave directions.
