The invention discloses a loading/unloading wing ring, a loading/unloading wing ring mechanism, and a power generator, a water activator and a water activating method thereof. The loading/unloading wing ring and the loading/unloading wing ring mechanism are formed by engagement of a loading/unloading-type wing plate and a ring-shaped support. The wing plate of the mechanism is extremely light but huge in size and strong in wind-receiving capacity, so that the power-generating capacity of the large-size single machine exceeds that of a steam turbine generator. The mechanism can be built on a high tower of more than 500 meters, or suspends in the air instead of the high tower to form a suspended large-size wind turbine generator, or directly floats on the water surface to form an overwater wind turbine generator or a wind-powered aeration water activator for aquiculture. The vertical loading/unloading wing ring mechanism can receive wind from all directions and works without needing a steering mechanism. The loading/unloading wing ring mechanism can be set at the top of a building or can suspend in the air in combination with a floating-type support, is connected with the ground through multiple traction cables extending in different directions and suspends in the air above an open space, and serves as an overhead wind power station integrating the functions of power generation, communication, sun shading, rain shield and decoration.
