A floating device includes a plurality of floating tube groups, and the floating tube group includes a floating tube body with an enclosed space inside, a middle section of the floating tube body is provided with a perforation communicating with the closed space and lower than the central axis, and the two tubes are respectively connected to the floating tubes The axial ends of the body and the area where the closed space is higher than the central axis. The body of the plurality of floating tubes is arranged at intervals, and the pipes connecting the two ends of the body of the floating tube are connected in parallel. The internal space of the body relative to the central axis performs a balance mechanism of injecting or extracting air at the same time, controlling the center of gravity of the float body to be maintained in the middle area of the float body, avoiding the deviation of the center of gravity, allowing the float body to be quickly and It floats or settles smoothly on the water surface and is not easily inclined.一種飄浮裝置，其包括複數浮管組，浮管組包括內部具有密閉空間的浮管本體，浮管本體的中段設有連通密閉空間且低於中心軸線的穿孔，並以兩導管分別連接浮管本體之軸向兩端且連通密閉空間高於中心軸線之區域，複數浮管組的浮管本體間隔排列，連接浮管本體兩端的導管並聯，藉此，利用浮管組的兩導管對浮管本體內部空間相對於中心軸線的雙向同時執行注入空氣或抽出空氣之平衡機制，控制浮管本體的重心維持在浮管本體的中間區域，避免重心傾偏的情事，讓浮管本體能夠快速且平穩地在水面上浮升或沉降而不易於傾斜。
