The invention is a device that the vertical axis windmill absorbs the kinetic energy of wind and drives the impeller to draw water； the traditional electric water truck uses the motor to drive the impeller to splash water and increase the oxygen content and fluidity in the water. However, it consumes a lot of electric energy. The device uses the vertical axis windmill to absorb the kinetic energy of wind and rotates the shaft, which is then transmitted through the umbrella gear set. When the impeller is driven to rotate, it will hit the water surface and splash water and create water flow, which can increase the oxygen content and fluidity of fish water.本創作係一種垂直軸風車吸收風之動能，而帶動打水葉輪以打水之裝置；傳統電動打水車是使用馬達帶動打水葉輪以打水濺起水花，增加魚塭水中之氧氣含量及流動性，然需消耗許多電能，本裝置運用垂直軸風車吸收風的動能而轉動轉軸，轉軸再經傘形齒輪組之傳動而帶動打水葉輪旋轉，打水葉輪會打擊水面而濺起水並創造水流，如此即可達增加魚塭水中之氧氣含量及流動性。
