VERTICAL SHAFT TYPE HYDRAULIC GENERATING EQUIPMENT, VERTICAL SHAFT TYPE HYDRAULIC GENERATING UNIT AND VERTICAL SHAFT TYPE HYDRAULIC GENERATING BLADE

摘要

To obtain a blade profile for maintaining blade performance capable of obtaining a high output while eliminating the insufficiency of the rigidity of a rear edge even if used in hydraulic generation which is necessary to receive a large load from a water flow by optimizing a blade profile shape constituting a blade.SOLUTION: Vertical shaft type hydraulic generating equipment 10 comprises: a generator 50 for generating power by receiving a rotation drive force from a water flow; a vertical rotating shaft 20 which is rotatably connected to the generator 50, and vertically hung down to a vertical direction; and a plurality of blades 13 which are arranged around the vertical rotating shaft 20 at substantially-equal intervals along a circumferential direction. A plurality of the blades 13 are formed while extending to the vertical direction, and function as a generator whose cross section shape is formed as a linear blade composed of a blade profile shape X, and a rear edge of the blade profile shape X is formed of a disc circular shape 13a having a curvature radius.SELECTED DRAWING: Figure 4
