Abstract

A first wind driven generator (10A) is provided with a rotor head (12) to which wind wheel blades (11) are mounted, a nacelle (14) for rotationally supporting the rotor head (12), a support strut for supporting the nacelle (14), an opening (16) formed in the front end of the rotor head (12) and taking in outside air, and air supply promoting guides (17A) mounted on the outer periphery of the opening (16) in the rotor head (12) and collecting outside air into the opening (16). The air supply promoting guides (17A) rotate with rotation of the rotor head (12) to cause the opening (16) to positively take outside air into the rotor head (12). The outside air taken into the rotor head (12) increases the amount of dissipation of heat of the surface of a rotor head casting (22), and as a result, the inside of the rotor head (12) can be efficiently cooled without requiring additional power.

Description

technical field [0001] The present invention relates to a wind power generator that generates electricity using a windmill that converts natural energy wind into rotational force. Background technique [0002] Conventionally, there are known wind power generators that generate electricity using wind power of natural energy. A wind power generation facility that applies wind force to a plurality of wings to generate rotational force and drives a generator through the rotor hub with the rotational force has high output power generation capability, and the wind power generation facility is installed not only in a row on plains but also on hills , a high location such as a mountain, or a place where a high wind speed can be obtained such as an ocean. [0003] Conventional wind power generators are equipped with a nacelle installed on a pillar: a rotor hub on which a windmill blade is mounted, a main shaft integrally rotatable with the rotor hub, and a speed booster coupled with...
