Abstract The present utility model discloses a new-type waterwheel rotating device, comprising a supporting plate, a rotating shaft, a rotating frame, a reinforcing ring and a power supply device, wherein the rotating frame comprises a rotating ring and rotating brackets, the rotating ring and the several rotating brackets being all fixedly connected, and one ends of the several rotating brackets being welded to a first cylinder assembly, a second cylinder assembly, a third cylinder assembly, a fourth cylinder assembly, a fifth cylinder assembly, a sixth cylinder assembly, a seventh cylinder assembly and an eighth cylinder assembly； and the first cylinder assembly comprises a cylinder, a seal pipe, a vent pipe, a water outlet and a water inlet, the cylinder being connected to the seal pipe, and the vent pipe being connected to the other end of the seal pipe. By means of air suction and water discharge through the piston motion of the cylinders, the vacuum cylinders under water float upwards. The cylinders above water discharge air and enter the water, which circulate in turn to make the waterwheel rotate continuously. The most important feature of this waterwheel is to utilize the buoyancy of water. 10, 8 Fig. 1 704 701 702 CA -703 Fig. 2本創作公開了一種水車轉動裝置，包括支撐板、旋轉軸、旋轉架、加固環、供電裝置，所述旋轉架包括旋轉環和旋轉支架，旋轉環和若干旋轉支架均固定連接，若干旋轉支架一端分別焊接有第一號氣缸元件、第二號氣缸元件、第三號氣缸元件、第四號氣缸元件、第五號氣缸元件、第六號氣缸元件、第七號氣缸元件和第八號氣缸元件；所述一號氣缸組件包括氣缸、密封管、通氣管、出水口、進水口，氣缸與密封管連接，通氣管連接在密封管另一端。通過氣缸的活塞運動進行抽氣和排水，水下的真空氣缸向上漂浮。水上的氣缸排氣入水，依次迴圈使水車不停旋轉。主要可以借用水的浮力是此水車最大的特點。
