Description

Wind Power Generators {A WIND ENERGY FACILITY}

The present invention relates to a wind power generation device, and more particularly, a blade applied to a wind power installation (wind power installation) based on a power that is rotated and driven according to wind speed, even with a low voltage provided from the outside of the blade. By allowing rotation of the power generation range, the wind power can be efficiently generated even at low wind speeds, and the blades are installed inside the blades, so that the blade can be rotated even when there is no wind. In one aspect, the present invention relates to a wind power generator that can be easily replaced and repaired.

In general, wind turbines are commonly found in wind turbines, where rotor blades (hereinafter referred to collectively as 'blades') are installed to obtain rotational amounts by natural wind speed and convert natural energy into electrical energy.

The expected effect of wind power generation is the power generation method using kinetic energy of wind, which has a great effect of replacing fossil fuels, and provides economic power supply to underdeveloped areas where it is difficult to supply electric facilities. Local land use can be rationalized by installing in the area, and in some specific areas, it can be used as a tourism resource by constructing large-scale wind power flyers.

Looking at the configuration according to the wind power plant, a fuselage having a rudder at the rear is installed in the upper part of the post so that the position is changed according to the wind direction, and the blade is rotatably installed at the tip of the fuselage, and the rotating shaft of the blade is a common rotation. A generator composed of an electron and a stator (induction coil) is installed to generate induction electromotive force according to the rotation of the blade, and the generated electromagnetic field is charged to a storage battery provided as a star, where electric energy from wind power generation is needed. It is effectively used.

Two or more blades are usually installed on a rotating shaft to be configured to rotate in one direction according to wind speed. The blades thus far developed satisfy the mechanical design and the variable conditions of the blade to obtain a smooth rotation design.

In order to obtain a relatively large amount of electrical energy, the size and shape of the blades are mainly designed. The relatively large blades start to rotate when the wind speed is more than 4 m / sec. Will accumulate.

Relatively, such wind power generation facilities are installed and operated in areas with high wind speeds.

On the other hand, when the size of some power generation facilities is very small, the wind power generation facilities themselves are often installed as sculptures in apartments and parks, and the electric energy obtained here is required for the environment for lighting street lamps and landscapes. It is effectively used. This is an example of temporarily utilizing electric energy charged depending on the wind power installed regardless of the specific region.

However, as the rotor blades become larger in size as described above, when the wind speed is 1 m / sec and the wind speed is insufficient, the rotor blade occupies a large amount of self-weight so that the rotor blade does not rotate at the low wind speed. In this case, the wind speed is not constant or the same in Korea and other regions where the wind speed is affected by the season. Therefore, the electrical energy actually generated by wind power is actually very low compared to the facility investment cost to obtain wind power. On the side.

Re-installation of the fuselage, including the bar should be made, the larger the volume of the component is larger, there is a closure that the special device must be mobilized by its own weight.

In addition, the rotation of the blade is made in the semicircular planar contact terminal installed on the fuselage side in the contact and short circuit state of the rotary connecting piece of the blade, the power supply for driving the rotation variable stage is always driven at the starting point of the plane contact terminal Since it is designed, since power is unnecessarily supplied even in the state in which the blades are accelerated and rotated, there has been a closed end in which the amount of electric energy used increases.

The present invention has been made to solve the above problems, it is possible to apply the rotation of the power generation range even at a low voltage provided from the outside of the blade on the basis of the power driven to rotate the blade in accordance with the wind speed The purpose of the power generation is to make efficient, as well as to be easily installed and replaced inside of the blade in the absence of wind in the absence of the rotation variable stage that induces the rotation of the blade can be easily replaced and repaired outside the blade. .
