Abstract
The invention discloses a vertical axis wind power/water power generator. Multiple ventilating openings are formed in the surface of a power lifting type blade which is connected with the generator; movable plates which are capable of changing the sizes of the ventilating openings are arranged; when the generated power of the generator is needed to be adjusted, the movable plates are driven to change the sizes of the ventilating openings, air flow on the surface of the blade enters into the blade through the ventilating openings but cannot propel the blade, thereby the rotation speed of the blade is reduced, and the generated power of the generator is raised; according to the preset output power of the generator, the sizes of the ventilating openings are adjusted in real time.
Description
Technical field
The present invention relates to vertical-axis generators, especially the vertical axis aerogenerator of lift-type blade and the generated output regulating method of hydroelectric generator and its blade structure.
Background technique
The Main Function of wind-driven generator braking mechanism has two aspects: one needs the blade of wind power generating set to maintain static when being overhaul of the equipments, two is avoid damaging generator set to need the blade of wind power generating set to maintain static when being and running into the powerful especially or typhoon of wind-force, and therefore braking mechanism is very important for wind-driven generator.Along with the rise of vertical axis aerogenerator, the various assemblies coordinated with vertical axis aerogenerator emerge in an endless stream, braking device is exactly one of them, consider the significance of braking device in wind-driven generator, select a kind of braking device of applicable vertical axis aerogenerator to be one of future vertical axis wind power generator development urgent problem.For solving the brake of vertical axis aerogenerator for topic, it is the braking device of a kind of vertical axis aerogenerator of 202215431U as China Patent Publication No., vertical axis aerogenerator comprises king-post, king-post is provided with the generator of vane group and external rotor, be provided with coupling between vane group and generator, coupling connects the rotor of vane group and generator respectively; Braking device comprises the ring-shaped brake dish be located on described coupling and the more than one braking device be fixed on king-post, and braking device comprises break and drives the power source of break, and break coordinates with described brake disc.When needs are braked generator, power source drives break, makes break hold described brake disc tightly, rely on the frictional force between break and brake disc, consume the kinetic energy of generator, generator amature speed is declined, thus reaches the object of brake power generating machine.Although this kind of braking device also can play the object reducing velocity of blade, its complex structure, and easily damages.The setting of braking device also can the generated output of regulator generator, and to guarantee that generator can reach full hair-like state, this full hair-like state is the optimum state of generator, and therefore the good of braking device performance directly affects electrical power generators performance soon.
