A multi-staged device for enriching oxygen content in water includes an electricity-powered waterwheel, an agglomeration water drop atomization device, a wind-powered oxygen enriching device, and a turn device, in which the agglomeration water drop atomization device receives agglomeration water drops generated by the electricity-powered waterwheel flapping on the water surface and atomizes the agglomeration water drops through a rotation mechanism for increasing the contact area between the water drops and air and enriching oxygen content in water. The agglomeration water drop atomization device and the wind-powered oxygen enriching device are each connected to a water intake mechanism. The water intake mechanisms directly draws water to the air, allowing the water drops to descend slowly for increasing the oxygen content of water, while saving the use of electricity. The turn device is used to adjust the orientation of a float platform of the electricity-powered waterwheel so that the float platform of the electricity-powered waterwheel is in alignment with the direction of wind, thereby achieving the objectives of effectively enriching the oxygen content in water and conserving the use of electricity.一種多級式增加水中溶氧設備,包含電力水車、團聚水細化裝置、風力增氧裝置與轉向裝置,其中,該團聚水細化裝置係承接電力水車拍打水面產生之團聚水,再透過轉動機制將團聚水細化,以增加水滴與空氣接觸面積,並將更多氧氣帶入水中;該團聚水細化裝置與風力增氧裝置分別結合一汲水機構,該等汲水機構係直接將水汲取至空中再緩慢滴落,以增加水中含氧量並可節省電力;該而轉向裝置則用以調整電力水車之浮台方向,使電力水車之浮台與風向一致;繼而達致有效增加水中溶氧量及節省電力之目的。
