Abstract
Official abstract text for this publication.
A water flow power generator includes a nacelle, a vane wheel that is disposed so as to be rotatable relative to the nacelle, and that is rotated by a water flow while including a plurality of blades, a power generator that is disposed inside the nacelle, and that generates electric power by using rotating power transmitted from the vane wheel, and a vane wheel rotation stopping mechanism that is disposed in the nacelle, that includes a rod which can enter the inside of a rotational trajectory of the vane wheel, and that stops the rotation of the vane wheel.
First claim
Opening claim text (preview).
What is claimed is: 1. A water flow power generator comprising: a nacelle; a vane wheel that is disposed so as to be rotatable relative to the nacelle, and that rotates while causing a plurality of vanes to capture a water flow; a power generator that is disposed inside the nacelle, and that outputs electric energy by converting rotational energy transmitted from the vane wheel into the electric energy; and a vane wheel rotation stopping mechanism having a rotation stopping member that is disposed on can outside periphery surface of the nacelle, the rotation stopping member including a rod that enters inside of a rotational trajectory of the vane wheel from outside of the rotational trajectory of the vane wheel, wherein the rod of the rotation stopping member which is slidable and extends in a longitudinal direction thereof to inside the rotational trajectory of the vane wheel. 2. The water flow power generator according to claim 1 , wherein the rod has a sharp corner having a sharp section oriented in a direction opposite to a rotation direction of the vane wheel, at a location intersecting at least the rotational trajectory. 3. A water flow power generator comprising: a nacelle; a vane wheel that is disposed so as to be rotatable relative to the nacelle, and that rotates while causing a plurality of vanes to capture a water flow; a power generator that is disposed inside the nacelle, and that outputs electric energy by converting rotational energy transmitted from the vane wheel into the electric energy; and a vane wheel rotation stopping mechanism having a rotation stopping member that is disposed on an outside periphery surface of the nacelle, the rotation stopping member including a restiform body that enters inside of a rotational trajectory of the vane wheel from outside of the rotational trajectory of the vane wheel, wherein the restiform body is deployed toward the inside of the rotational trajectory of the vane wheel.
