The invention is a kind of impeller structure of water vehicle to improve the oxygen content. It mainly forms a number of water holes and more than one water breaking structure on the main body of the arc-shaped impeller. Besides using the arc-shaped impeller to collect water to increase the lifting height, it also reduces the resistance of water when pumping through the water breaking structure, and reduces the motor load, so as to improve the oxygen content, service life and power saving efficiency of the aquaculture pond.本創作係為一種提昇含氧量之水車葉輪結構，主要於弧狀葉輪主體上形成數撥水孔及一個以上之破水結構，利用弧狀葉輪集水增加揚水高度外，更透過破水結構於葉輪打水時，減少水的阻力，進而降低馬達負載，藉以提昇養殖池的含氧量及使用壽命和省電效能。
