power generation device

Abstract

The invention provides a power generating device. A power generating device according to an embodiment includes: a rotating shaft, a slip ring, a detection shaft, and a position detector. The rotating shaft through which the wiring from the propeller passes rotates with the propeller. One end of the slip ring is coupled to the rotating shaft. The detection shaft is provided at the other end of the slip ring and rotates together with the rotation shaft. The position detector detects the rotational position of the detection shaft, thereby detecting the rotational position of the propeller.

Description

technical field [0001] The invention relates to a power generating device. Background technique [0002] Propeller generators are known that generate electricity by rotating a propeller with wind, ocean currents, and other fluids. For example, a wind power generation device converts mechanical energy of a propeller rotated by receiving wind power into electrical energy by using a generator. [0003] The propeller power generator may include a position detector such as an encoder that detects the rotational position of the propeller of the generator. Some power plants of the prior art have such a position detector on the propeller shaft. The position detector detects the rotational position of the propeller shaft, thereby detecting the rotational position of the propeller (for example, see Japanese Patent Application Laid-Open No. 2011-208635). [0004] However, propeller shafts generally have a large shaft diameter, which may cause the position detector to become larger w...
