Description

[0001] A Portable Wind Generator [0002]

The present invention relates to a portable wind power generator, and more particularly, to a portable wind power generator in which, when a rotating body having a blade is rotated by wind, a power transmitting body disposed inside the rotating body rotates to generate electricity through a generator, The present invention relates to a portable wind power generator.

A wind turbine generates electric energy by rotating a power turbine using the force of a blade or a specific structure rotated by the wind.

In the case of nuclear power generation, which is generally used to produce electrical energy, the treatment and storage of materials and materials contaminated with spent fuel rods and radiation used in the power generation process becomes a problem. In the case of thermal power generation, which produces electricity by making steam steam using the thermal energy obtained by burning coal or oil, and rotating the turbine by using it, in the process of producing electric energy, Harmful gases such as cargo and nitrogen oxides are generated and are harmful to the environment.

However, in the case of wind power generation that uses wind to generate electrical energy, it is environmentally friendly because it is a clean electricity production system that does not generate harmful substances in the process of producing electrical energy. In recent years, along with solar cells and fuel cells, which are eco-friendly electric energy production methods, worldwide attention and technology development for wind power generation are being actively carried out.

Generally, wind power generators are installed in large size in tower form on mountainous area, beach or sea where wind is constantly blowing, and many wind turbines are gathered in groups maintaining a constant interval and installed as large capacity wind turbine generators. In recent years, small and mid-sized wind turbines, which are large enough to be installed and used in a large-tower type wind turbine as well as in a backyard of a home, are under development. Therefore, it is necessary to develop portable portable power generator that is portable and portable, easy to install, and easy to use.

On the other hand, the technology related to the conventional wind power generator described in the Japanese Patent No. 10-1181729 and the Japanese Patent No. 10-1169225 discloses that the power generation efficiency is increased by using a variable wind turbine blade or a horizontal lift type vertical shaft structure or the like Although it can be seen, it does not provide the function or structure design of a portable wind turbine capable of moving regardless of the location of the wind turbine.

That is, it is possible to grasp the technical idea that the conventional techniques increase the convenience through the conversion of the structure of the wind turbine generator and the efficiency of the operation process, but it is difficult to derive a simple structure wind turbine generator .
