<P>PROBLEM TO BE SOLVED: To provide a wind power generation device accelerating wind speed and increasing wind power. <P>SOLUTION: The wind power generation device includes a chimney stack part 4 including a spiral fan 5 and extending in a vertical direction, a generator 10A converting rotary motion of the spiral fan 5 to electric power in a power generation room 10 at a lower end position of the chimney stack part 4, an air duct 2 supplying flowing air of higher temperature than ambient temperature to the spiral fan 5 on a leeward side with a heat source part 1 set at an windward side, and an exhaust part 7 provided at a tip of the spiral fan 5 of the chimney stack part 4. The wind power generation device is provided with a wing 3 in the air dust 2 having a cone bent part B bulging from the windward side to the leeward side, and accelerates flow of air due to temperature difference toward a low pressure zone C between the spiral fan 5 and the wing 3. <P>COPYRIGHT: (C)2009,JPO&INPIT |
