A kind of agitating device floated on the what water surface, comprising the elemental floating body on a floating what water surface, the power source on the setting what elemental floating body, the gear unit that is positioned apart from the what power source of two-phase and one be pivoted what this etc. on gear units and part submerge in water and be in the stirring parts of Europe Dan Aykroyd (Oloid) shape. The power source can interlock the rotation of one of them gear unit, and sequentially interlock the stirring parts and the rotation of another gear unit, and then the stirring parts is made continuously to carry out overturning beat. By the high equal gear units of mechanism freedom, and the geometry for cooperating the stirring parts special, make the stirring parts that can carry out overturning and beat simultaneously when being driven, reaches the stirring of omnibearing stereo formula, and fluid is made to form the round ripple constantly spread, generate good uniform mixing effect.一種可浮於水面上的攪拌裝置，包含一浮於水面上的浮體單元、一設置於該浮體單元上的動力源、二相間隔地設置於該動力源上的傳動單元、及一樞設於該等傳動單元上且部分沒入水中並呈歐羅伊德(Oloid)形的攪拌件。該動力源可連動其中之一傳動單元旋轉，並依序連動該攪拌件及另一傳動單元旋轉，進而使該攪拌件連續地進行翻轉偏擺。藉由機構自由度高的該等傳動單元，並配合該攪拌件特殊的幾何結構，使該攪拌件在被帶動時可同時進行翻轉及偏擺，達到全方位立體式的攪拌，並使流體形成不斷擴散的圈狀波紋，產生良好均勻的攪拌效果。
