Abstract:
1. A large capacity wind power generator, comprising: an outer rotor including an upper partitioning plate having a plurality of spokes formed along a circular circumference of the upper partitioning plate at equal intervals and a side partitioning plate formed on one side surface of the outer rotor, the outer rotor having a lower surface and the other side surface which are open, wherein the side partitioning plate is formed to have an area that is smaller than a half of the entire circumferential area of the outer rotor, and spaces between the respective spokes are open so as to facilitate an inflow of the wind through the side surface of the outer rotor; a windmill formed inside the outer rotor to be rotated by wind flowing through the outer rotor, wherein the windmill comprises blades which are rotated by the wind flowing through wind inlets, a center post which prevents movement of the blades in left and right directions, and upper and lower surface plates placed on upper and lower sides of the blades, wherein the blades extend in a radial direction from the center post and each of the blades is in the shape of an arc; a wind indicator plate, which is rotatable according to the wind direction, installed on an upper side of the upper partitioning plate so as to position the outer rotor in a wind blowing direction; a bottom frame formed on the bottom of the wind power generator; a middle frame installed on an upper side of the bottom frame, being apart from the bottom frame, and formed of a plurality of shafts; an upper frame provided on an upper side of the middle frame, being apart from the middle frame; a plurality of fixing shafts extending upward from edges of the bottom frame and connected up to edges of the upper frame through the middle frame; a support block extending from the bottom frame up to a height between the middle frame and the upper frame to support the outer rotor and the windmill; a first bearing formed in the center of the upper surface of the upper frame; a third bearing formed in the center of the upper surface of the middle frame; a first rotary shaft which vertically penetrates the windmill and is inserted into the first bearing and the third bearing, wherein the first rotary shaft is rotated as the blades are rotated; a second bearing formed in the center of the lower surface of the upper frame, wherein the second bearing has a diameter that is larger than that of the first bearing and the third bearing; and a second rotary shaft which is inserted into the second bearing and extends up to the center of the upper partitioning plate; wherein the outer rotor and the wind indicator plate are positioned between the support block and the upper frame, and the support block has a horizontal section area that is equal to that of the outer rotor; wherein the wind indicator plate comprises a plurality of vertical plates formed at a height that corresponds to the second rotary shaft and positioned in parallel to each other, being apart from each other, a first horizontal plate connecting the upper sides of the vertical plates, a second horizontal plate connecting the middle sides of the vertical plates, and a third horizontal plate connecting the lower sides of the vertical plates, wherein front end portions of the vertical plates, the first horizontal plate, the second horizontal plate, and the third horizontal plate are open.
