Description

  The present invention relates to a vane structure of a vertical axis wind power generator, and in particular, a vertical axis type including a movable baffle unit that blocks wind or effectively reduces air resistance by opening and closing a hole provided on the vane. It relates to the vane structure of a wind power generator.

  The vertical axis wind power generator has a vertical main shaft to which a plurality of vanes are attached at intervals along the peripheral surface of the main shaft. Each vane generally has a front surface and a back surface that are two outwardly curved surfaces and an inwardly curved surface corresponding to each other. The inwardly curved surface of the vane receives the head wind and blocks the flow of the air flow, so that the vane is pushed by the wind and rotates the main shaft. Subsequently, the rotational force of the main shaft is transmitted to a plurality of generator sets to generate power.

  The vanes of the vertical axis wind power generator are circumferentially spaced around the main shaft, and the inwardly curved back surface of the preceding vane faces the outwardly curved front surface of the subsequent vane. When wind is blown against the inwardly curved back surface of the vane, it is also blown against the outwardly curved surface of the other opposite vane. That is, only the wind blown against the inwardly curved back surface of the vane helps to effectively rotate the main shaft, and the wind blown to the outwardly curved front surface of the vane acts as a resistance against the rotation of the main shaft. .

  All of the vanes of conventional vertical axis wind generators are complete plates with no openings formed on them. When wind is blown to the outward curved front surface of the vane, the wind is guided to the outside of the vane by the outward curved front surface, and air resistance can be reduced. Nevertheless, the pushing force generated by the wind blown against the inwardly curved back side of the other vanes is reduced because the wind is still blocked by the relatively large area of the vane. Unfortunately, the wind power generator is less effective because the wind power that rotates the main shaft is reduced.

  A main object of the present invention is to provide a vane structure of a vertical axis wind power generator that rotates a main shaft by reducing air resistance of the vane body and effectively blocking wind by the vane body.

  In order to achieve the above object and other objects, a vane structure of a vertical axis wind power generator according to a preferred embodiment of the present invention includes a plurality of circumferentially spaced apart wind turbine main shafts.

Therefore, the first movable baffle unit covers the hollow screen so that it can be opened and closed from one side adjacent to the rear recess. When the rear surface recess of the vane receives wind, wind is blown to the first movable baffle unit to cover the hollow screen, and the through hole on the front plate portion of the rear surface recess of the vane body is closed to effectively block the wind. On the other hand, when the rear concave portion of the vane receives a tailwind, the first movable baffle unit naturally opens the through hole on the front plate portion, thereby reducing the air resistance of the vane rotation. That is, the vane of the present invention having the rear concave portion that receives the head wind can effectively use the wind force without being adversely affected by the opposite vane having the rear concave portion that receives the tailwind. Therefore, the main shaft of the wind power generator can be easily rotated by the vane.
