Description

  The present invention relates to a wind power generator capable of efficiently obtaining power using wind energy.

  In recent years, wind power generators using wind energy have been developed as a power source capable of ensuring the preservation of the global environment and the safety management of energy facilities.

  There are various types of wind turbines provided in the wind power generator, and it is generally possible to classify them into two types: horizontal axis wind turbines and vertical axis wind turbines.

  Among them, the propeller type wind turbine is the most popular among horizontal axis wind turbines. In general, this propeller type windmill has a higher efficiency with respect to wind and better maneuverability when the number of blades is larger. In addition, since the highest efficiency point of the propeller type windmill is in a low wind speed region, it is possible to generate power from a low wind speed.

  By the way, in this propeller type windmill, since the rotation axis of the windmill is parallel to the wind blowing direction, it is necessary to control the direction with respect to the wind. Propeller-type wind turbines tend to be larger because the efficiency of capturing wind is improved as the diameter of the rotor is increased, and the wind can be captured more efficiently at higher locations. However, considering the maintainability, as the diameter of the rotor increases, the tower becomes taller and the blade becomes longer, which makes it difficult to inspect and repair.

  In addition, the vertical axis windmill rotates at a lower rotation and higher torque than the horizontal axis windmill, and the rotation axis is perpendicular to the direction in which the wind blows, so there is no need to control the direction of the wind. As this vertical axis wind turbine, a Darrieus type, a gyromill type, a Savonius type or a combination thereof is used depending on the application. Among these, the Savonius type is attracting attention as a wind power generator that is smaller than the propeller type windmill and has no particular limitation on the installation location.

  Therefore, as a conventional technique, referring to the Savonius-type wind power generator shown in Patent Document 1, this wind power generator is provided with a wind turbine part with a plurality of blades attached to the upper part of the vertical shaft and a gear attached to the lower part on the left and right sides. The blades of the respective wind turbine units are arranged in parallel so that the blades overlap each other in a non-contact manner, and the blades enter each other. When driving, the blades of the left and right windmills are rotated in reverse so as not to come into contact with each other, and power is generated with the driving force.

  However, since the wind power generator of the above-mentioned Patent Document 1 has a configuration in which the blades are arranged in parallel so that the blades enter each other, both of them rotate even if they are rotated in synchronization with each other. When a failure occurs in the synchronous rotation of the blades, there is a risk that the left and right blades may come into contact with each other, leading to an accident such as breakage of the blades.
