A kind of waterwheel is fetched water the improvement construction of blade,It is that consecutive intervals angle concatenates and fixes each blade part in what shaft,Being includes that its both ends have inserted tooth portion and wear the fixed hub of conjunction for shaft,And fixed hub outer radial is connected with the blade of fetching water of corresponding tubular portion,And the water repellent portion of the outside end formation curved arc shape for blade of fetching water,And air hole is equipped at its inner end,It more enables simultaneously and offers several apron holes at the water repellent portion and tubular portion back side for blade of fetching water,And be equipped in the opposite two sides of tubular portion and Da Shui Zhu piece,Make through Da Shui Zhu piece to water flop and stir,Other than dissolved oxygen effect to increase water,And when blade of fetching water in water by rotating out,Enable water in tubular portion other than being flung outward along water repellent portion and getting rid of and shed,Several apron holes for also enabling water open up from water repellent portion and tubular portion simultaneously and scattered spill is come,It allows water more fully to disperse around and increases the contact with air,And then allow the dissolved oxygen better effect of water for dissipating and spilling,Increase the efficiency and the uniformity of water dissolved oxygen.一種水車打水葉片的改良構造，是連續間隔角度串接而固定於轉軸上的各葉片部件，是包括一其兩端具有嵌齒部而供轉軸穿合的固定軸套，且固定軸套外側徑向固接有相對應之管狀部的打水葉片，而打水葉片的外側末端形成彎弧狀的撥水部、以及其內側端處設有透氣孔，同時更令打水葉片的撥水部與管狀部背側處開設有數個散水孔，並又在管狀部相對的兩側設有打水鯺片，使透過打水鯺片對池水拍擊與攪拌，來增加池水的溶氧效果以外，並在打水葉片由水中繞轉出來時，令管狀部內的水除了沿著撥水部被向外抛甩散出以外，同時也令水從撥水部與管狀部上開設的數個散水孔而散灑開來，讓水更充分的向四周散開而增加與空氣的接觸，進而讓散灑的水之溶氧效果更佳，增加池水溶氧的效率及均勻度。
