A horizontal axis wind turbine (HAWT) includes: a tower, a rotor rotatably mounted on an upper portion of the tower, an upper crank unit mounted in an upper portion of the tower and operatively rotated by the rotor, a lower crank unit mounted in a lower portion of the tower and linked to the upper crank unit to be driven and rotated by the upper crank unit, a kinetic-force conversion apparatus connected to and rotatably driven by the lower crank unit to convert the kinetic energy to an output electricity, and a nacelle secured to a lower portion of the tower for mounting the kinetic-force conversion apparatus in the nacelle, with the nacelle approximating to the tower bottom for enhancing stability and safety of the HAWT, and also for reducing the installation, operation and maintenance cost of the HAWT. |

1. A horizontal axis wind turbine (HAWT) comprising: a tower, a rotor rotatably mounted on an upper or top portion of the tower, an upper crank unit mounted in an upper portion of the tower and operatively rotated by the rotor when facing to and rotated by wind, a lower crank unit mounted in a lower portion of the tower and linked to the upper crank unit to be driven and rotated by the upper crank unit, a kinetic-force conversion apparatus connected to and rotatably driven by the lower crank unit to produce and convert a kinetic energy to electricity output, and a nacelle secured to a lower or bottom portion of the tower for mounting the kinetic-force conversion apparatus in the nacelle. |
