This creation is a water tanker that dynamically adjusts the depth of the water. It is designed to allow the waterwheel to stimulate the water and the energy of the water to be redistributed to save energy and improve work efficiency. The composition comprises an impeller, at least one impeller group capable of rotating and pumping water and flowing, and a sliding bracket capable of guiding the displacement of the impeller group up and down. When the impeller group runs at high speed at night, the reaction force between the impeller group and the water body forms a lift force due to the increase of the rotational speed, so that the impeller group can automatically lift upwards to reduce the water depth and water body resistance, thereby avoiding unnecessary flow generation effect and saving electricity. When the amount of dissolved oxygen in the daytime is supersaturated, the impeller group is lowered due to the low speed operation, so that the depth of the water inlet is relatively increased. In addition to saving the energy of generating water, the working efficiency of the water in the culture pond can be improved.本創作為一種可動態調整入水深度的養殖池水車,旨在讓水車用於激發水花和造成水流的能量能夠重新分配,以節省能源並提高工作效率。其組成包括一浮筏、至少一可升降地旋轉打水及造流的葉輪組,以及能夠導引該葉輪組上、下位移的滑動支架。當葉輪組在夜間高速運轉時,葉輪組與水體的反作用力因轉速增加而形成一升力,使葉輪組能夠自動向上舉升而減少入水深度及水體阻力,避免產生不必要造流效果而節省電力;日間溶氧量過飽和狀態下,葉輪組因低速運轉而下降,使入水深度相對增加,除了節省產生水花的能量以外,還可提高對養殖池水造流的工作效率。
