JPH0968152A - Vertical type wind power source moving device having spiral rotary blade - Google Patents

Abstract

PROBLEM TO BE SOLVED: To form a device settable even in the vicinity of a house, by decreasing an installation area with also a noise not spreading to the periphery and escaping to the upward, in a wind power source moving machine which can quickly respond to changing of a wind direction always from omnidirection to generate a rotary motion in no relation to the wind direction when wind power is generated in any place. SOLUTION: In a wind power source moving machine, a spiral rotary blade 1 is mounted in a vertical type rotary shaft 2, and this rotary shaft is mounted in a vertical type supporting frame utilizing a bearing or the like to be held by a bearing 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical wind power source device having spiral rotating blades, which is designed to respond to winds blown from all directions. The present invention relates to a wind power generator in which blades are installed vertically and a device for holding and installing the same.

[0002]

2. Description of the Related Art Conventionally, as a wind power source drive device of this type,
A 2- to 4-blade propeller-type wind-powered engine or a Robinson anemometer in which a bowl-shaped molded body is attached to a horizontal bar perpendicular to the rotation axis is generally used.

[0003]

Among the matters described in the prior art, in the former, it is almost difficult to immediately respond to a sudden change in the direction of the wind. It must be installed and operated in the direction of the greatest common divisor, and noise is generated logarithmically with respect to the wind speed, which is not suitable near a house, and the installation area is also a safe area around the propeller size. Considering also, it is impossible to install easily anywhere.

Also, the latter Robinson type is not suitable for a wind power source of a large size because of its strength, and even if possible, it can be easily installed anywhere considering noise and safety of the surroundings. It doesn't happen.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to constantly respond to wind from all directions and to reduce noise due to wind speed. Prevention and installation is also possible in a narrow space, for example, on the roof of a building, to use for private power generation.

[0006]

In order to achieve the above object, the wind power device of the present invention has spiral rotary blades attached to a vertical rotary shaft, and always rotates in response to wind from all directions. Installed to enable effective use of wind force, it holds the rotating shaft, holds the upper and lower bearings firmly with steel angles, etc., so that it will not tip over against large winds. It is something that is fixed.

A cylindrical accelerating ventilation tube is attached to the upper part so as to surround the rotor, in which a spiral rotary blade is attached to a vertical rotary shaft.

A speed adjusting governor is attached to the lower part to prevent overspeed.

A flywheel can be attached to the rotary shaft and can be used as needed.

Attach a reverse rotation prevention device. However, it is unnecessary if the spiral rotary blade is slightly concave.

[0011]

The present apparatus, which has spiral rotary blades attached to a vertical rotary shaft, is installed on a shore, the rooftop of a building, or the like, and rotates by receiving wind. It is always possible to effectively convert wind in all directions into rotary motion. When the number of rotations exceeds a certain level, the speed adjustment governor acts to adjust the rotation speed.

If a flywheel is attached to the rotary shaft, it is possible to maintain a certain rotational speed even if the wind slightly decreases.

[0013]

EXAMPLES Examples will be described with reference to the drawings. 1 to 3, a spiral rotary blade is formed of FRP or metal and attached to a metal shaft, and bearings using rotary bearings are provided at both ends of the shaft and the lower support portion. The windmill assembled in this way is installed vertically. The output is taken out and utilized by the conduction of gears or pulleys provided at the bottom of the rotary shaft.

[0014]

Since the present invention is constructed as described above, it has the following effects.

Since the spiral rotary blade of claim 1 has no directionality and always effectively receives wind from all directions and converts it into a rotational force, wind from any direction can be utilized.
As in the past, it is not necessary to survey the wind direction in advance. However, only wind power survey is enough.

Since the noise generated by the vertical spiral rotary blade of claim 1 is blown upward by the rotation, it is unlikely to disturb the surroundings unlike the conventional system.

The vertical unit type of claim 2 has an installation area of
Since it is not necessary so much, it can be installed on the roof of a building, etc., depending on the scale.

Even the large assembly type of claim 3 does not require a vast surrounding site unlike the conventional propeller system,
Also, since it does not affect the surroundings in terms of noise, safety, etc., it can be installed near a house rather than in a remote place like the conventional method. Becomes
