A double-layer reverse rotation vertical shaft power machine adopting a horizontal combined movable wing relates to the technical field of green energy generating sets, which includes main body devices, movable wing devices, transmission devices and a self-clutch device; each movable wing device includes combined wings vertically arranged along the circumferential direction of the main body devices, each combined wing includes combined shafts and combined movable wings connected to the combined shafts, and the combined shafts vertically arranged along the circumferential direction are alternately arranged according to the axial length. The combined shafts that are alternately distributed along the circumferential direction in turn can effectively stagger the adjacent combined movable wings and avoid the mutual interference between the adjacent combined movable wings, thereby reasonably using all combined movable wings, fully obtaining the outside potential energy and improving the efficiency.
