Power generator

Abstract

【課題】川の流れや海流等の流体の流れによる自然エネルギーを利用して効率的に発電することができる発電装置を提供する。 【解決手段】一端部に流体の流入口1aが、他端部に排出口1bが形成された筒状の第1の導管1と、この導管1内に軸線を一致させて設けられ、外周面と第1の導管の内周面との間に排出口に向けて漸次断面積が小さくなる流体の流路Fを形成する円錐状の内壁部2と、流路F内に軸線に対して傾斜して設けられ、流路F内に導入された流体に円周方向の流れを形成させる複数枚の案内ブレード3と、排出口に臨む位置に回転板8が軸線廻りに回転自在に設けられるとともに、回転板の排出口と対向する面に流体の流れを受けて回転させるための複数の翼9が円周方向に間隔をおいて配置された回転部材6と、この回転部材の回転により発電を行う発電手段とを備える。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a power generator capable of efficiently generating power utilizing natural energy by the flow of fluid such as the flow of a river or an ocean current.SOLUTION: The power generator includes: a cylindrical first conduit 1 having a fluid inflow port 1a formed at one end and a discharge port 1b formed at the other end; a conical inner wall part 2 provided inside the conduit 1 matching an axis, for forming a flow path F of fluid whose cross sectional area is gradually reduced toward the discharge port between an outer peripheral surface, and an inner peripheral surface of the first conduit; a plurality of guide blades 3 inclined to the axis and provided inside the flow path F, for making the fluid introduced into the flow path F form the flow in a circumferential direction; a rotation member 6 for which a rotating plate 8 is provided so as to be freely rotated around the axis on a position facing the discharge port and a plurality of blades 9 for receiving and rotating the flow of the fluid are arranged at an interval in the circumferential direction on a surface facing the discharge port of the rotating plate; and power generation means for generating power by the rotation of the rotation member.
