As shown in Japanese or the like, wind generators are known for obtaining an electrical turn the generator by the wind turbine.

In such a conventional wind power generator, a wind turbine is installed by selecting a point where a uniform wind blows, the wind turbine is rotated while changing the direction of the wind turbine according to the direction of the wind, and the wind turbine is connected to the wind turbine. I try to turn the generator.

However, since the size of wind power changes from moment to moment, and there are many moments when the direction of the wind changes suddenly or disappears at all, the wind turbine of the conventional wind generator does not rotate uniformly. Therefore, there is a problem that a stable generator output cannot be obtained.

In order to solve such a problem, various measures have been taken such as changing the pitch of the wind turbine to obtain a constant rotation depending on the magnitude of the wind speed. However, such a measure complicates the structure of the wind turbine, Further, when the wind stops, the wind turbine cannot be rotated as before, and there is a problem that it cannot be an effective means for obtaining a stable output.

[0006] As described above, the method of utilizing wind power has been remarkably reduced in practical use due to the unstable output characteristic of wind, and is gradually disappearing as the use of the internal combustion engine is expanded. However, there is an enormous amount of wind energy on the earth, and if wind energy can be used effectively, it is possible to provide extremely clean energy compared to internal combustion engines that generate combustion products. There is.

[0007] Therefore, an object of the present invention is to provide a wind power take-out device which can efficiently use the force of the wind and take it out as stable power.

The wind is rectified inside 3 and escapes upward, and the impeller 12 is rotated by the rectified wind. If you rectify the wind like this,
The direction of the wind with respect to the impeller 12 becomes constant, and stable wind force can be obtained. Further, since the wind moves inside the wind tunnel 3 accommodating the impeller 12 , the wind that has entered the wind tunnel 3 acts on the impeller 12 without waste, and efficient rotation of the impeller 12 is achieved.

This embodiment has the above-mentioned structure, and its operation will be described below. When the wind enters from the wind intake 4,
The wind is given an upward force while moving in the inclined passage 5, and is introduced into the wind tunnel 3. In the wind tunnel 3, the wind is rolled up into an ascending air current, and the wind is blown during the ascent by the wind tunnel 3.
After being rectified by the shape of, and hitting the impeller 12, it comes out above the wind tunnel 3. As a result, the impeller 12 is always acted on by a wind that strikes the front of the impeller from the same direction, so that stable rotation of the rotating shaft 11 can be obtained.

Further, the winds entering from the six wind intake ports 4 are converged into one in the wind tunnel 3, and the converged winds act on the impeller 12 inside the wind tunnel 3 without waste. A large wind force is applied to the impeller 12, and the rotating shaft 11 connected to the generator 13 can be rotated with a large force.

Further, since the wind is taken in from the six wind inlets 4 provided so as to surround the entire circumference of the outer shell 2, the wind is always introduced into the wind tunnel 3 even if the direction of the wind changes suddenly. Therefore, the impeller 12 can be stably rotated.

In addition to the action of the wind tunnel, the speed increasing effect of the shape of the outer shell 2 also acts on the wind. First, the wind hitting the lower edge of the outer shell 2 is divided into an inner surface and an outer surface of the outer shell as shown in FIG. 6, and moves along both side surfaces thereof .
Since the wind passing through the inner surface of the outer shell 2 needs to travel a longer distance than the wind passing through the outer surface (from the above-mentioned relationship of L ₁ > L ₂ ), as a result, pressure is applied to the inside and outside of the wind tunnel 3. There is a difference,
The velocity of the wind on the inner surface increases. The outer shell 2
When the wind that flows on the inner surface of the fan is accelerated, the amount of air that enters the inclined passage 5 and the wind tunnel 3 increases, and as a result, the wind force that acts on the impeller 12 increases.

On the other hand, when the movement of the wind is small or stops and the required amount of wind is not introduced from the wind intake port 4, the wind is generated as follows.

First, in the daytime, when the surface of the outer shell 2 is heated to a high temperature by the heat of the sun, water is pumped up into the water channel 18 on the inner surface of the outer shell and the water is returned along the inner surface of the outer shell. Let As a result, the water in the water channel 18 is transferred to the outer plate 17 of the outer shell 2.
It is heated by the heat of the
When water is circulated, the water evaporates, and the steam heats the inside of the hollow portion 14 of the outer shell 2.

When the hollow portion 14 becomes high in temperature as described above and a temperature difference occurs between the hollow portion 14 and the outside, the temperature difference causes the outer shell 2
An ascending airflow is generated around the, and the airflow generated by the ascending airflow enters the wind tunnel 3 from each air intake 4 and rotates the impeller 12. Further, in this case, the steam generated in the hollow portion 14 flows through the steam pipe 28 to operate the steam power generator 29 to generate electricity.

On the other hand, at night when the outer shell is not heated by the sun, the heater 24 at the lower end of the outer shell 2 is operated to heat the air in the vicinity of the wind intake port 4. The thus heated air moves rapidly to the surroundings because the molecular motion becomes extremely vigorous, but immediately after that, cold air enters from the surroundings, so that winds enter the wind inlet 4 one after another. Then, the wind is introduced into the wind tunnel 3 to rotate the impeller 12.

As described above, in the apparatus of this embodiment, if there is natural wind, the wind is efficiently introduced into the wind tunnel 3 to rotate the impeller 12, and if there is no wind or the air volume is not sufficient. Since the impeller 12 is rotated by generating wind, a constant rotation of the impeller 12 can be obtained and a stable generator output can be obtained.

Rainwater is used as the water that collects the rainwater and returns it to the water channel 18, and the pumps 23 and 37 for pumping the water to the water channel 18 are driven by electricity obtained from the generator 13 and the steam power generator 29. By doing so, it is not necessary to supply water or energy from the outside to the power generator, and the device can be operated at low cost.

Although one impeller 12 is provided in the wind tunnel 3 in the above embodiment, a plurality of impellers may be attached to the same rotary shaft or a plurality of rotary shafts.

Further, the shape of the outer shell 12 is not limited to the hexagonal pyramid shape as shown in the figure, but may be formed in other polygonal pyramid shape or conical shape.

Furthermore, in the above, an example in which the wind power take-out device of the present invention is used for power generation has been shown, but the present invention is not limited to this, and for taking out power for driving agricultural machinery, civil engineering machinery, etc.,
The wind power take-out device of the present invention can also be used.

[0041]
