A kind of waterwheel is fetched water the construction of blade,It is continuously to be concatenated by array different angle and fix the blade part makers-up in what shaft,And it includes that there is wearing for inserted tooth portion to close on shaft fixing sleeve at a both ends that each blade part, which is,Radial outside is connected with corresponding tubulose and fetches water blade,And enable fetch water blade outboard ends formed slightly in curved arc shape water repellent portion,And air hole is equipped at its inner end,When blade of fetching water can be enabled to protrude into water,Water energy is allowed enough smoothly to flow into the pipe for blade of fetching water,And when blade of fetching water rotates from bottom to top,Through the effect of centrifugal force,The water beaten in oxygen leaf is enabled to be thrown away outward along the water repellent portion of end to distant place,The water for dissipating and spilling is allowed sufficiently to contact Hou with air,It falls into the water again,What pond can more be blazoned by enabling dissolved oxygen dissipate the water spilt,And then the effect of raising water oxygenation,Increase the dissolved oxygen effect in pond.一種水車打水葉片的構造，是由數組不同角度連續串接而固定於轉軸上的葉片部件組成者，而各葉片部件是包括一兩端具有嵌齒部的穿合轉軸固定套上，徑向外側固接有相對應的管狀打水葉片，並令打水葉片外側末端形成略呈彎弧狀的撥水部、以及其內側端處設有透氣孔，即可令打水葉片伸入水中時，讓水能夠順利的流入打水葉片之管內，並在打水葉片由下向上繞轉時，透過離心力的作用，令打氧葉內的水沿著末端的撥水部而被向外甩出至遠處，讓散灑出去的水充分與空氣接觸後，再落入水中，令溶氧散灑的水更能廣佈於水池，進而提高池水增氧的作用、增加水池的溶氧效果。
