Wind-collecting tower for a wind power generator

Abstract

The present invention relates to a wind-collecting tower for a wind power generator, including a cylindrical wind tunnel which stands upright on a base, and which has a circumferential surface with wind inlet ports for introduction of wind; a guide unit having guide passages arranged on the circumference of the wind tunnel to guide wind introduced from the outside to the wind inlet ports; louvered windows formed on the guide passages of the guide unit and spaced apart from the wind tunnel, such that the wind introduced into the guide unit is guided downwardly by the guide unit and introduced into the wind inlet ports of the wind tunnel; and one or more support frames which are arranged transversely on the respective guide passages, and which have one or more through-holes covered by the louvered windows.

1 . A wind-collecting tower for a wind power generator, the wind-collecting tower comprising:
 a cylindrical wind tunnel ( 10 ) which stands upright on a base ( 3 ), the cylindrical wind tunnel ( 10 ) having a circumferential surface in which a plurality of wind inlet ports for introducing wind are defined;   a guide part ( 20 ) disposed on a circumference of the wind tunnel ( 10 ), the guide part ( 20 ) having a plurality of guide passages ( 7 ) for guiding wind introduced from the outside into the wind inlet ports ( 5 );   a plurality of louvered windows ( 30 ) disposed spaced from the wind tunnel ( 10 ) on the guide passages ( 7 ) of the guide part ( 20 ) to guide the wind introduced into the guide part ( 20 ) downward from the guide part ( 20 ), thereby introducing the wind into the wind inlet ports ( 5 ) of the wind tunnel ( 10 ); and   at least one or more support frame bodies ( 40 ,  50 ) arranged transversely on each of the guide passages ( 7 ), the support fame bodies ( 40 ,  50 ) having one or more through-holes ( 23 ) covered by the louvered windows ( 30 ),   wherein the guide part ( 20 ) comprises:   a plurality of wind-collecting plates ( 13 ) arranged in a redial direction along the circumference of the wind tunnel ( 10 ); and   a plurality of guide plates ( 15 ) vertically spaced from each other between the wind-collecting plates ( 13 ) and arranged on the circumference of the wind tunnel ( 10 ) so that the guide plates ( 15 ) together with the wind-collecting plates ( 13 ) defines the guide passages ( 7 ).   
     
     
         2 . The wind-collecting tower of  claim 1 , further comprising a blowing unit ( 60 ) comprising: a rotation shaft ( 61 ) rotatably disposed to pass through a center of a top plate ( 41 ) corresponding to the wind tunnel ( 10 ); a plurality of wind roses ( 63 ) disposed on an upper portion of the rotation shaft ( 61 ) and rotated by wind passing above the top plate ( 41 ) to rotate the rotation shaft ( 61 ); and an impeller ( 65 ) disposed on a lower portion of the rotation shaft ( 61 ) and synchronously rotated with the wind roses ( 63 ) to generate an air current flowing from an upper end of the wind tunnel ( 10 ) to a lower end. 
     
     
         3 . The wind-collecting tower of  claim 1 , further comprising at least one or more support frame bodies ( 40 ,  50 ) arranged transversely on each of the guide passages ( 7 ), the support fame bodies ( 40 ,  50 ) having one or more through-holes ( 23 ) covered by the louvered windows ( 30 ). 
     
     
         4 . The wind-collecting tower of  claim 3 , wherein the louvered windows ( 30 ) comprises:
 a window frame ( 31 ) defining an outer circumference thereof and coupled to the through-holes ( 23 ); and   at least one or more louvered plates ( 33 ) attached to the window frame ( 31 ) to cover an opening ( 35 ) of the window frame ( 31 ), the louvered plates ( 33 ) being arranged inclined with respect to a plan defining the opening ( 35 ) of the window frame ( 31 ).   
     
     
         5 . The wind-collecting tower of  claim 4 , wherein the louvered plates ( 33 ) are attached to an outer surface of the window frame ( 31 ) to extend inclinedly downward from the outside of each of the through-holes ( 23 ) toward the inside.
