Solar power generating apparatus

A solar power generating apparatus, comprising:

• a body (100) having a three-dimensional shape to guide air flowing from an outside to ascend and being provided with an acceleration flow path (142) on top of the body to induce a bottleneck phenomenon of the ascending air;
• and
• a power generation fan (200) mounted on the acceleration flow path (200),
• wherein the body (100) includes:
• a base (120) in which an ascending space (102) is formed;
• and a cap (140) placed on an upper end of the base (120), in which the acceleration flow path (142) is provided and a ceiling surface is spaced apart from an upper end of the base (120) by a predetermined interval,
• wherein the base (120) includes:
• an inner body (128) having a hollow cylindrical shape with an empty inner space;
• columns (122) erected at a predetermined interval along an outer peripheral surface of the inner body (128) and having an inner empty space through which the ascending air passes;
• and a heat plate (124) mounted between the columns (122) to be upwardly inclined from the outside to an inside with a difference in height, wherein an inner end thereof is spaced apart from the outer peripheral surface of the inner body (128) by a predetermined interval, and wherein the ascending space (102) is formed between the inner end of the heat plate (124) and the outer peripheral surface of the inner body (128),
• wherein legs (130) are provided on a bottom of the base (120) such that the base (120) is spaced apart from the ground by a predetermined height,
• whereby, when the body (100) is heated by sunlight, external air is introduced through a spacing between the heat plates (124) at a lateral side of the base (120), while external air also flows from a lower portion of the base (120) and rises along the ascending space (102) and an inside of the columns (122) to guide an ascending air current so that the ascending air current rotates the power generation fan (200), thereby enabling power generation.
