Disclosed are a method and device for generating a hydrodynamic force with a spiral body. The device comprises the spiral body which is of a spiral structure or a helical structure. On the basis of fluid, with the fluid as a core and an electromagnetic effect, electrical energy, or battery energy, or magnetic energy, or solar energy, or particle energy, or nuclear energy, etc. or wind energy, or air energy, or luminous energy or the combination thereof drives or rotates the spiral body which meets a specific design. As the spiral body is driven, the fluid or space and energy thereof are converted into a force; meanwhile, an acting force and a counter-acting force are generated, leading to braking, and power is generated and supplied; meanwhile, anti-gravity is involved, and spatial power is distorted. The method and the device can reduce power conversion and output links, reduce energy loss and increase conversion.
