Abstract

PURPOSE:To improve the precision and the reliability of a blade-fixing-angle changing device by detecting a blade-fixing angle of a wind power prime mover by no-contact for enabling to change the blade-fixing angle. CONSTITUTION:A blade-fixing angle detector consists of a photoelectric distance detector 14, and fixed at ends of a fixed plate 9 and an operation shaft 6 to be used for measuring the distance to a movable plate 11 to reflect light. Since the distance is taken out as an electric signal and the detector 14 is not brought into contact with a power shaft 1 and the like, a blade-fixing-angle changing device can be obtained with high durability, reliability, and precision. Besides, a detector using supersonic wave can be similarly applied.

Concerning prime movers - Configuration of conventional examples and their problems A linear or rotary potentiometer is used as a blade mounting angle detector for conventional wind power prime movers. However, since all of them are contact type, there are problems with durability, lifespan, and firstly, reliability. An example of this is shown in Figures 1 and 2.

生じるな−ど、信頼性。In the figure, as the rod 22 of the cylinder 21 expands and contracts, the movable plate 23 moves back and forth, and the attachment angle of the connected blades 24 changes. In this blade attachment angle variable device, the detector 25 can measure the blade attachment angle by detecting the position of the movable plate 23 with respect to the fixed plate 26. A potentiometer or the like is used as a detector to measure the distance between the fixed plate 26 and the movable plate 23, but since it is installed in the rotating part of the wind motor, centrifugal force acts on the contact part, causing the signal to be distorted. There were problems in that disturbances occurred and the detector itself was damaged. Furthermore, with contact-type detectors, the contact parts may wear out or deteriorate due to sliding, resulting in errors in signal values, which can lead to reliability issues.
