Abstract

The invention discloses a Darrieus type wind driven generator. The Darrieus type wind driven generator comprises an equipment base; a horizontal generator platform is installed on the equipment base,a generator with an input shaft vertically facing upwards is fixedly installed on the generator platform through a generator support, a Darrieus type wind wheel assembly is coaxially and fixedly connected to the upper end of the input shaft of the generator, and the overall rotation of the Darrieus type wind wheel assembly can drive a rotor of the generator to operate through the input shaft so asto generate electricity. When the equipment stalls, a first over-speed protection rope, a second over-speed protection rope and a third over-speed protection rope pull a first Darrieus blade, a second Darrieus blade and a third Darrieus blade inwards in the direction close to a center shaft of a Darrieus wind wheel; and the torque of the first Darrieus blade, the second Darrieus blade and the third Darrieus blade is reduced, so that the aim of reducing the rotating speed of the central shaft of the Darrieus wind wheel is fulfilled, and the aim of overspeed protection is fulfilled.

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 ...
