Floating device

The utility model provides a floating device. The floating device comprises a floating box, an embarkation platform and a balance mechanism. The buoyancy tank can float in water; the embarkation platform is located above the buoyancy tank; a plurality of slideways are symmetrically arranged at the bottom of the embarkation platform, and a gap is formed between any two adjacent slideways; the slide ways are arc-shaped, and the concave surfaces of the slide ways are oppositely arranged; the balance mechanism comprises connecting sliding pieces arranged corresponding to the sliding ways, the bottoms of the connecting sliding pieces are fixedly connected with the buoyancy tanks, and the tops of the connecting sliding pieces are connected with the sliding ways of the embarkation platform in a sliding mode. When the floating box swings in any direction due to the impact of sea waves, the floating box drives the connecting sliding piece to slide along the sliding way at the bottom of the embarkation platform, and th
