Title (EN) DUCT FOR HYDRAULIC POWER GENERATION DEVICE AND HYDRAULIC POWER GENERATION DEVICE
(FR) CONDUIT POUR DISPOSITIF DE PRODUCTION D'ÉNERGIE HYDRAULIQUE ET DISPOSITIF DE PRODUCTION D'ÉNERGIE HYDRAULIQUE
(JA) 水力発電装置のダクト及び水力発電装置
Abstract:
(EN) The purpose of the present invention is to provide a duct for a hydraulic power generation device, the duct being disposed in front of a rotor blade and having spiral grooves formed in an inner wall peripheral surface thereof for rotating a water flow. The duct 1 disposed in front of the rotor blade of a hydraulic turbine has an inner diameter which gradually becomes smaller from the front part to the rear part. The inner wall peripheral surface of the duct is formed with a plurality of spiral grooves 2 for rotating a passing water flow. A rear end of an inner wall surface is opposed to a front surface of a forward inclined portion 7A of the rotor blade 7.
(FR) Le but de la présente invention est de fournir un conduit pour un dispositif de production d'énergie hydraulique, le conduit étant disposé devant une pale de rotor et ayant des rainures en spirale formées dans une surface périphérique de paroi interne de celui-ci pour faire tourner un écoulement d'eau. Le conduit (1) disposé devant la pale de rotor d'une turbine hydraulique a un diamètre interne qui régresse progressivement de la partie avant à la partie arrière La surface périphérique de paroi interne du conduit est formée avec une pluralité de rainures en spirale (2) pour faire tourner un flux d'eau passant. Une extrémité arrière d'une surface de paroi interne est opposée à une surface avant d'une partie inclinée vers l'avant (7A) de la pale de rotor (7).
(JA) 本発明は、ロータブレードの前部に配設されるダクトの内壁周面に、水流を回転させるためのらせん状の溝を施条した、水力発電装置のダクトを提供することを目的としている。 水車のロータブレードの前部に配設されるダクト1の内径を、前部から後部へかけて次第に小径とするとともに、ダクトの内壁周面に、通過する水流を回転させるための複数条のらせん状の溝2を形成し、かつ内壁面を後端部がロータブレード7の前向傾斜部7Aの前面と対向させてある。
