    Abstract: The present invention relates to a movable and semi-submerged power generator using a waterwheel turbine, which can easily be moved to a location where a flow of a fluid occurs, prevents movement by current of water due to being a semi-submerged type, and efficiently produces energy by means of a flow rate control and cutoff of the fluid and expansibility of the turbine. The power generator comprises: an upper structure having first and second structures including first and second balancing tanks and first and second machine rooms; a lower structure disposed on the lower portion of the upper structure and including a fluid flowing hole, a first round, and a fluid guide hole through which the fluid can flow; a turbine rotated by the movement of the fluid; an energy generation means for producing electricity by the turbine; and a fixing means. Thus, the power generator is floatable and movable on water so as to be moved to and installed in various locations. The first and second balancing tanks are filled with the fluid such that the power generator can be semi-submerged, and the height of the turbine is disposed at a position so that a shaft can be placed above the water surface such that the turbine is smoothly rotated, while preventing shaking by waving of the fluid and turning of the power generator, thereby improving energy production efficiency. Also, the fluid under the water surface is guided in a direction capable of operating the turbine while maximally preventing disruption to the flow of the fluid moving to the turbine through the first round of the lower structure, thereby improving energy production efficiency.

    Abstract: A device for application in a fan configuration is configured, in particular, to be directly driven by an electric motor. In the fan configuration, a centrifugal fan wheel is mounted to rotate in unison with a drive shaft. The centrifugal fan wheel, for producing a directed airflow, is surrounded by a fan housing. A seal is disposed in an admission orifice, for largely filling in an air gap between the centrifugal fan wheel and the inner surface of the fan housing. Such a configuration improves the housing and sealing thereof for an application in a vacuum cleaner by having the sealing device be embodied as a sealing ring linked to a buffer part out of the fan housing, which part tightly surrounds the admission orifice.
