Abstract
The utility model relates to a lift-drag complementary type vertical shaft wind-driven generator, which belongs to the field of electricity generation by wind. Existing large wind-driven generators in using can not be started by self, and the existing large wind-driven generators can be started by auxiliary power in starting. In this way, the cost of wind-driven generators is increased, and energy is consumed. The utility model is composed of a lift-force type upper wind wheel, a resistance type lower wind wheel, and a generator. The utility model can be automatically started and braked, and the speed of the utility model can be regulated by the utility model.
Description
The utility model is a kind of lift-drag complementary upright shaft wind motor, belongs to wind power generation field.
The large-scale wind driven generator that uses all can not start voluntarily at present.When starting, need auxiliary power to start.So both improve the cost of wind energy conversion system, expended the energy again.
For a kind of moving large-scale wind that just can start of need not assisting is provided, the utility model spy has proposed a kind of lift-drag complementary upright shaft wind motor.
Lift-drag complementary upright shaft wind motor of the present utility model is made of vertical tail,, horizontal tail, following wind wheel, damping plate, gear-box, generator bay and base; Wherein vertical tail, and horizontal tail are formed wind wheel on the lift-type, are loaded on the top of this wind energy conversion system; Following wind wheel and damping plate constitute wind wheel under the resistance type, are loaded on the wind wheel bottom, are connected by the speed governing box between following wind wheel and damping plate; Last wind wheel is coupled by gear-box with following wind wheel, and and generator electric; Have vortex lift-rising groove at horizontal tail along spanwise.
The working procedure of this lift-drag complementary upright shaft wind motor: the diameter of wind wheel is less than wind wheel on the lift-type under the resistance type.During wind, following wind wheel begins to rotate, and makes that by gear-box going up wind wheel starts, and rotates with higher speed.When wind-force is excessive, make damping plate turn to brake by the speed governing box, with the rotating speed of restriction wind energy conversion system.
The resistance type wind wheel and the lifting wind wheel of this lift-drag complementary upright shaft wind motor are coupled by gear-box, and the speed ratio that is maintained fixed makes fan operation at the higher state of efficient.Utilize the big characteristics of the little torque coefficient of resistance type wind wheel tip-speed ratio, the starting wind energy conversion system carries out speed governing and speed limit to wind energy conversion system.Lifting wind wheel is an integral blade, and its horizontal spanwise has vortex lift-rising groove, and during the blower fan stall, the horizontal tail front end is sagging naturally, and rotating speed is when high, and front end upwarps, and vertical tail, is at a slight tilt, and this starting and speed limit to blower fan is favourable.The resistance type wind wheel blade is equipped with the speed governing box, acts on aerodynamic force on the damping plate, inertial force, elastic force and adjusts the plate face angle that facings the wind by the speed governing box, with the rotating speed of control blower fan.
