[Correction 29.10.2014] according to Rule 26

The present invention relates to a cylindrical windmill of the wind turbine is variable wing angle according to the wind direction.

Wind power generation technology has been developed in various forms such as propeller type and cylindrical wing structure, but it is not easy to achieve constant power generation because the strength of wind power is not constant.

The structure in which the vertical wing angle is variably spread on the outer surface of the cylindrical body of the wind power generator was developed in Korea Patent Nos. 10-0620948, 10-0743475, 10-0938669 (the first technology group), and the cylinder of the wind power generator of the epicenter. The structure of generating wind power by angularly folding the angle of the wing vertically from the sieve surface was developed in Korea Patent Publication No. 10-2010-0084805 and Korean Patent Registration No. 10-1121012 (the second technology group), and these were vertical They are designed to expand or close near the edges of the wings, which usually means that each vertical wing forms a cylindrical and coaxial circle, and the wings only expand when the wind is above a certain level of wind pressure (first technology group), Winds entering the blades to generate wind power (second technology group), with the stop period from the standstill to the moment when the initial rotation is started (the wind spreading or folding the wings Geotyieoseo with the approach to the condition), the development of generators cylindrical windmill ever possible the generation by rotation along the direction of the wind, even fine wind pressure is not carried out.

In addition, the technology to allow the wind cylinder's rotating cylinder to eccentrically rotate on the rotating shaft to expand or close the wing plate according to the wind direction has been developed in Korea Patent Registration No. 10-0938669, but the eccentric shaft is installed only at the upper end of the rotating shaft, causing a vibration phenomenon. However, the structure has a complicated problem.

In addition, when the rotor blade receives the wind from the rotor of the wind turbine, the rotor enters into the cylinder and is rotated by the wind pressure generated by the space.The rotor cylinder and the rotation force are separated by an eccentric bearing installed between the cylinder and the shaft. Developed by Korea Patent Publication No. 10-2010-0084805 to bond the wind induction plate to the top of the eccentric bearing so that the vertical wing plate receives the wind by the rotational force of the eccentric bearing interlocked according to the action of the wind induction plate. However, the rotation is difficult when the wind is weak due to the wing is entered, the eccentric bearing is exposed to have a problem that the durability is lowered.

The present invention is to solve this, an object of the present invention is to install a vertical wing plate radially on the cylindrical rotating body, each vertical wing plate receives a rotational force and a fixed bar that functions as a hinge axis for adjusting the rotation angle, the eccentric from the rotating shaft It is an organic action of the link part which adjusts the angle of inclination of the vertical wing plate by forming the angle according to the wind direction by the eccentric disc which is rotated by the eccentric protrusions which are bonded to each other. It is to provide a cylindrical windmill of the wind power generator with a variable wing angle according to the wind direction to perform the power generation function.

Another object of the present invention is that the eccentric disc for adjusting the angle of the vertical wing plate to the eccentric function to the eccentric protrusion to the eccentric protrusion to also be eccentric to the upper portion of the eccentric coupling which is connected to the vertical axis receiving the rotational force from the vertical wing plate to be bonded to act as an eccentric function With eccentric transmission through eccentric filling, the rotating shaft rotates forward, and through the eccentric coupling, the wind angle is varied according to the wind direction that allows the angle of the vertical wing plate to be adjusted without noise through the link part eccentrically according to the wind direction. To provide a cylindrical windmill of the generator.

Another object of the present invention is to fix one of the first and second link shafts that form the link portion for transmitting the eccentric force to the vertical wing plate fixed to the fixed shaft to function as a power transmission shaft by link coupling separate It is to provide a cylindrical windmill of the wind turbine is variable wing angle according to the wind direction so that no link control means of the.
