JP2001193628A - High-efficient propeller for wind power generator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a wind power generator which can supply a large volume of electricity under limited geographical conditions by means of propellers easily rotated by gentle wind, thus achieving high profitability and generating clean energy with high efficiency. SOLUTION: In order to receive natural wind as much as possible, a propeller is formed with a sunken portion 1 and keel-like stripes 2 radially extending from the center of the propeller. By providing three to six of these propellers well-balanced like stairs, rotational frequency and torque can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a parabolic keel-like streak attached to a side of a propeller that receives wind to improve the efficiency of wind power generation.
It is intended to mount three to six propellers in a stepwise manner.

2. Description of the Related Art Conventionally, three blades of a propeller of a wind power generator have convex blades in order to reduce the resistance of a portion hit by the wind, so that the blades are hardly affected by natural wind. I have. It is good for turning the propeller with power and sending the wind to the rear, but it seems to be inefficient for receiving the energy of natural wind.

[Problems to be Solved by the Invention] In order to eliminate the drawbacks of the present invention, a concave surface is formed on a blade portion so as to be easily affected by natural wind, and maple and other seeds are subjected to buoyancy of air. Taking into account the principle of falling while rotating, research has been carried out on improving the efficiency by applying several parabolic keels or streaks to these propellers.

[Means for Solving the Problems] In order to increase the overall efficiency, a concave portion is provided on the surface of the propeller that receives the wind, and a parabolic keel-like line is formed. Three or more blades are stacked in a stepwise manner evenly in a well-balanced manner. However, if too many blades are stacked, the efficiency will not be improved.
I found that it spins almost twice as stable.

[Embodiment of the Invention] In order to carry out the present invention, a three-blade propeller is first attached to a model motor, and when the wind is blown, it cannot be rotated unless it is very close. Even if three similar blades were piled up and blown the wind, they did not rotate midway. However, turning over the blades (1) made it easier to catch the wind, and shifted the blades one by one in a stepwise manner (3 ) When a wind with the same conditions is blown, it starts rotating at a considerably high speed. To make them more efficient, apply a few parabolic streaks or keel-like objects so that the maple and other seeds rotate and fall down under the buoyancy of wind and air (2). It becomes more susceptible to wind energy and increases rotational power.

[Effects of the Invention] Since the present invention is configured as described above, the force of natural wind applied to one blade is set to 1 and the force of 3 is applied to the second blade. Since the force of 3 is applied, the force of 6 is applied, and the force of 3 is also applied to the third blade, so that a total of 9 forces are applied. The weight of the three blades acts as a flywheel, so the rotation is smooth, the rotation is stable, and the maximum efficiency is achieved when the wind energy is evenly applied to all the blades. Also, ten times more strength is required.

Claims (1)

[Claims] 1. A wind generator propeller is provided with a recess (1) on the wind receiving side, and a maple or other kind of streak or keel for the seeds to fall while rotating in the air is attached to the center of the propeller. A parabolic shape is applied from the outside to the outside to make it easy to receive the natural wind (2), and three or more propellers are attached in steps (3) between the blades of the first propeller.
