Summary of the invention
The purpose of this utility model has just provided a kind of new adjustable wind energy power device with vertical shaft of lift-type sail area, and this device can improve the resultant moment of force that is in each fin generation under the different conditions in the wind driven electric plant, improves the utilization ratio of wind energy.
The purpose of this utility model is to realize like this, the adjustable wind energy power device with vertical shaft of a kind of sail area, by support, decide arm, motor, rotating shaft, wing curtain and backguy and form, it is rack-mount to decide arm, motor flexibly connects with the last overhanging arm of deciding arm, spool flexibly connects with the following overhanging arm of deciding arm, one end of backguy is fixed on the motor, the other end is fixed on the spool, the dual-side of wing curtain is fixed in the backguy, one end of wing curtain is fixed on the spool, and the length of backguy is 2 times of wing curtain length at least.
Last swing arm flexibly connects with the last overhanging arm of deciding arm, and downward moving arm flexibly connects with the following overhanging arm of deciding arm, and motor is fixed on the swing arm, and spool is fixed on the downward moving arm.
On the interior corresponding surface of last swing arm and downward moving arm, have slotted hole along its length.
The purpose of this utility model can also realize like this, the adjustable wind energy power device with vertical shaft of a kind of sail area, by support, decide arm, motor, rotating shaft, wing curtain and backguy and form, it is rack-mount to decide arm, motor flexibly connects with the following overhanging arm of deciding arm, spool flexibly connects with the last overhanging arm of deciding arm, one end of backguy is fixed on the motor, the other end is fixed on the spool, the dual-side of wing curtain is fixed in the backguy, one end of wing curtain is fixed on the spool, and the length of backguy is 2 times of wing curtain length at least.
Last swing arm flexibly connects with the last overhanging arm of deciding arm, and downward moving arm flexibly connects with the following overhanging arm of deciding arm, and motor is fixed on the downward moving arm, and spool is fixed on the swing arm.
On the interior corresponding surface of last swing arm and downward moving arm, have slotted hole along its length.
The adjustable wind energy power device with vertical shaft of sail area described in the utility model by swinging the angle of swing arm change wing curtain simultaneously, is adjusted the area that length changes fin of pulling out of wing curtain; Make each fin on the residing position separately, adjust the air-flow angle of attack better when wind driven electric plant rotates, the net torque of system is increased, improve wind energy utilization, particularly effect is more obvious under starting state and low wind speed state.
