Abstract

PROBLEM TO BE SOLVED: To increase the self-starting force (a force to automatically start rotation) and the rotation force of a wind mill, in the wind cup of a vertical shaft type paddle type wind mill used as a wind force generating device of a wind force prime mover. SOLUTION: A hollow triangular cone 1 having a bottom formed in a circle is laid down to form a wind cup body, and a bottom forms a wind receive surface. An umbrella blade consisting of umbrella ribs 2 and a curtain 3 is arranged externally of the bottom of a triangular cone 1 to form a wind cup. The umbrella blade is opened and closed by a force of wind as the umbrella blade is rotated by slight looseness left at the curtain 3. By increasing a wind receiving area through opening and closing of the umbrella and decreasing resistance of the wind cup by the wind cup itself after the umbrella blade is rotated in a 180 deg. arc centering around a vertical shaft, the self-starting force and the rotation force of a wind mill are increased.

2. Description of the Related Art A vertical axis type paddle type wind turbine has a wind axis on a vertical axis, receives wind from the wind axis, rotates around the vertical axis, and obtains wind power. The vertical axis paddle type windmill is typically represented by a hollow hemisphere, but there is a limit to the expansion of the wind receiving surface.
In addition, when the air is rotated by 180 degrees about the vertical axis from the wind, a large vortex of air is generated in the hollow portion serving as the wind receiving surface. The force for starting to rotate) and the rotational force are weaker than those of other wind turbines, so that they are less used as wind power generators.

According to the present invention, a hollow triangular pyramid having a circular bottom surface is laid horizontally to form a main body of a wind turret, and a bottom surface is used as a wind receiving surface. An umbrella blade composed of a curtain is attached to the curtain, and the umbrella blade opens and closes while rotating with the force of the wind due to the slack, which enlarges the receiving area and the wind after 180 degrees rotation around the vertical axis The problem is solved by reducing the resistance of the wind itself.

BEST MODE FOR CARRYING OUT THE INVENTION A hollow triangular pyramid with a circular bottom is
Attach an umbrella bone about one-third the height of the triangular pyramid outward from the bottom surface, and attach several places at equal intervals in the circumferential direction. The attachment angle of the umbrella is the extension of the line connecting the circumference and the vertex of the bottom surface of the triangular pyramid. On the umbrella bone, a curtain with a slack is stretched over the entire surface in the circumferential direction to form an umbrella blade composed of an umbrella bone and a curtain. Because it enters and exits freely, it contracts to be larger than the umbrella bone when it receives wind from the inside, and to close when it receives wind from the opposite direction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
1 is a hollow triangular pyramid formed by cutting a plate made of a suitable material such as vinyl chloride into a circular shape with a circular bottom, and is provided with a hollow. Reference numeral 2 denotes an umbrella bone made of a suitable material such as bamboo and having a length approximately one third of the height of the triangular pyramid, protruding from the triangular pyramid and firmly fixed to the inner surface. A plurality of umbrella bones are attached at equal intervals in the circumferential direction. 3 is a thin curtain that has tension and is made of a material such as polyethylene that is resistant to water.
Adhere to the bottom of the umbrella and the triangular pyramid with a little slack between the umbrella. The curtain spreads to the outside of the umbrella bone by the amount of slack when it receives the wind inside, and enters the inside of the triangular pyramid between the umbrella bone when it receives wind from the opposite direction.

As described above, the umbrella wing-type wind shim of the present invention is as follows.
When the umbrella blade attached to the lower part of the hollow triangular pyramid receives air inward, the area is expanded by the force of the wind, and a stronger wind power is obtained, and the wind rotates 180 degrees around the vertical axis When receiving wind from the apex of the triangular pyramid, the curtain of the umbrella blade enters the inside of the triangular pyramid, and the vortex of the air in the hollow part can be changed to a shape close to direct current by the curtain, which allows Its own resistance is reduced, and a strong rotating force can be easily obtained.
