The invention discloses a cyclotron stabilizer and a floating ocean structure. The cyclotron stabilizer comprises a four wing plates and a driving device, wherein a first wing plate and a second wing plate are arranged on one side of the bottom of the floating ocean structure; a third wing plate and a fourth wing plate are arranged on the opposite side of the bottom of the floating ocean structure; the four wing plates tilts and extends under the water; a symmetric relation is formed between the tilting direction of the first wing plate and the tilting direction of the fourth wing plate; a symmetric relation is formed between the tilting direction of the second wing plate and the tilting direction of the third wing plate; the driving device drives the first wing plate and the fourth wing plate to synchronously move and also drives the second wing plate and the third wing plate to synchronously move; the first wing plate and the second wing plate are subjected to mirror movement by taking a water flow direction as a mirror axis; the third wing plate and the fourth wing plate are subjected to mirror movement by taking the water flow direction as a mirror axis. Through the cyclotron stabilizer and the floating ocean structure, the movable wing plates are designed and are subjected to mirror rotation movement, so that the straightening speed of the floating ocean structure can be accelerated; the unnecessary energy loss can be reduced; the energy-saving effect can be achieved.
