Description

  The present invention relates to a wind power generator that can be installed on a steel tower such as a power transmission tower in a state where a plurality of wind turbines are connected so that power can be efficiently obtained.

  In recent years, wind power generators using wind energy have been developed as an energy source for preserving the global environment and ensuring safety management of energy sources.

  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 type wind turbines. Among the horizontal axis wind turbines, the most popular is the propeller type wind turbine.

  In this propeller type windmill, since it is necessary to make the rotation axis of the windmill parallel to the wind blowing direction, it is necessary to control the wind direction. 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.

  Therefore, in order to install a conventional propeller type windmill, it is necessary to construct a dedicated high steel tower on a dedicated site, and there is a problem that the construction cost increases.

  Therefore, in order to solve the above problems, as shown in Patent Document 1, a technique for installing a wind power generator equipped with a wind direction gyro on a power transmission tower has been developed.

  This patent document 1 has a structure in which a wind power generator equipped with an impeller and a generator and a wind direction gyro are attached to the top of a transmission tower, and the wind power generator is opposed to the wind by the wind direction gyro. It is aimed at.
