Abstract

A) Technical field: Variable pitch propeller
B) Problems to be solved: The existing small wind power generator rotates too fast when there is a lot of wind, resulting in excessive wear of the power plant and propeller bearings, and cannot maintain a constant amount of electricity.
C) Task solution: not fixed propeller, but with angle adjustable propeller, and connect spring to adjust propeller pitch according to the increase or decrease of lift.
D) Effect: As the pitch is adjusted according to the air flow, the propeller always rotates at a constant speed and prevents overspeed.

Description

Automatic variable propeller by air volume {CONTROLABLE WIND POWER PROPELLER}

The present invention is to prevent the wind turbine from rotating at an excessive speed due to excessive wind volume.

The ship's propellant has a variable pitch propeller that controls the propulsion by adjusting the angle of the propeller.

Existing small wind generators rotate too fast when there is a lot of wind, resulting in excessive wear of the power plant and propeller bearings, and cannot maintain a constant amount of electricity.

If you receive excessive air flow, lower the propeller angle so that the lift is small on the propeller.

Sharps to prevent over-rotation require no brakes and no additional devices for constant power generation. There is no need for an overcurrent protector.

1 is a view showing the change of the propeller angle according to the wind strength

If you generate a certain amount of wind for wind power, and measure the propeller angle change with increasing wind strength, you will be able to see that the propeller rotates even when the wind is strong.
