Title:
BLADE POSITION AND ATTITUDE AUTONOMOUS CHANGING WIND TURBINE
Document Type and Number:
Japanese Patent JP2022068798
Kind Code:
A
Abstract:
To provide a novel type wind turbine which realizes drastic reform and remarkable efficiency enhancement of a rotational blade type wind turbine suitable for mid-to-small sized wind turbines, by inventing a mechanism and a function capable of avoiding a fundamental problem that a conventional wind turbine of the same type innately has; that is, a rotation impeding effect of the wind turbine by headwind, and presenting a blade position and attitude autonomous changing wind turbine having the same.SOLUTION: A blade position and attitude autonomous changing wind turbine according to the present invention includes a new mechanism and a new function named a dual-axis circumferential rotation blade system where the wind turbine itself is capable of autonomously changing the position and the attitude of the blade mounted thereto in accordance with a wind direction, and has a mechanism and a function to change the position and the attitude of the blade for taking in tail wind sufficiently or letting headwind escape entirely, autonomously with the force of the wind alone. With the mechanism and the function, the wind turbine can enhance the efficiency of converting a wind force into a rotational force and gain a high rotational force as compared with a conventional wind turbine having the equivalent size.SELECTED DRAWING: Figure 2
