The invention discloses a Darrieux-type wind power generator, which comprises an equipment base, on which a horizontal generator platform is installed, and a generator platform with an input shaft vertically facing upwards is fixedly installed on the generator platform through a generator bracket. machine, the upper end of the input shaft of the generator is fixedly connected with the shaft center with a Darrieus-type wind wheel assembly, and the overall rotation of the Darrieus-type wind wheel assembly can drive the rotor of the generator to run through the input shaft to generate electricity; the device of the present invention When stalling, the first overspeed protection rope, the second overspeed protection rope and the third overspeed protection rope respectively move the first Darrieux-type blade, the second Darrieux-type blade and the third Darrieux-type blade toward Pulling inward from the direction of the central axis of the Darrieus rotor reduces the torque of the first Darrieus blade, the second Darrieus blade, and the third Darrieus blade, thereby reducing the Darrieus wind The purpose of the rotational speed of the wheel central shaft has reached the purpose of overspeed protection.
Description
technical field [0001] The invention belongs to the field of wind power generation. Background technique [0002] In severe windy weather, the Darrieus-type wind rotor assembly will rotate at an excessive speed driven by the natural wind. At this time, the rotation speed of the Darrieus-type wind rotor assembly has exceeded the operating load of the generator. protection, there is a risk of damage to the equipment. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a Darrieus-type wind power generator with overspeed protection and a working method. [0004] Technical solution: In order to achieve the above object, a Darrieux-type wind power generator of the present invention includes an equipment base on which a horizontal generator platform is installed, and the generator platform passes through the generator bracket A generator with an input shaft facing upwards is fixedly ...
