Field of the Invention The present invention relates to a wind power system capable of taking out energy from wind power and converting it into various types of mechanical energy or electrical energy, and more particularly to a vertical wind power system in which blades are vertically arranged. It is a thing.

[0002]

2. Description of the Related Art Various wind turbines have been devised and used for a long time as means for converting wind energy into mechanical energy. In addition, various clean and economical wind power generators capable of converting this wind energy into electric energy and extracting it have been proposed and developed.

In this conventional wind power generator, generally, the blade portion that receives the wind is fixed to the rotating shaft. In other words, a portion of the blade that opens and closes receives the wind. The area has not changed freely.
In addition, as shown in FIG. 13, the conventional type is generally a type in which a cover 100 is provided on one side or a so-called Darrieus type using wings.

[0004]

By the way, in this wind power generator, since the area of the blade is constant or the mounting angle of the blade is fixed and constant, the wind is efficiently received and the energy of the wind is received. It is difficult to take out to the maximum. Furthermore, such wind power generators are not particularly novel in structure such as the wind turbine part that receives the blades, and many of them are similar in appearance, and they are not enough in terms of novelty. Was also lacking.

Therefore, in view of the above circumstances, the present invention has an object to provide a vertical wind power device which can take wind energy into an effective maximum source and is excellent in design.

[0006]

The wind pressure detecting means detects the wind pressure received by the blades, and the driving means opens and closes the blades vertically and / or horizontally according to the wind pressure to change the area of the blades.

[0008]

According to the first aspect of the invention, even if the direction of the wind changes, the front surface of the base body is always constant by the steering means.
For example, the impeller can be maintained in the upwind direction, and each impeller is configured such that the attitude of the impeller with respect to the wind at the upwind position during the revolution operation is always constant. As a result, the position and angle of the rotating piece in the rotating chamber for each revolving impeller is changed at each revolution position, but the angle of the blade with respect to the wind direction is the same for all impellers at the same revolution position. There is no such thing.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a vertical cross-sectional view showing a vertical wind turbine according to the present invention. This vertical wind turbine is installed in a hull 1 that constitutes a base body, and a center in which the hull 1 is always in phase with the same direction. Axis 2 and steering means 3
An impeller 4, a rotating piece 5, a blade 6, a rotating plate 7,
And a generator 8.

In this embodiment, the hull 1 is floated on a lake and marshes, and the steering means 3 which will be described later is arranged so that the bow of the hull 1 always faces the windward direction. In this example,
Although the base body is composed of a hull, of course, the present invention is not limited to this, and it is also suitable for installation on land, in mountains, rivers, or remote islands. The base may be supported.

The central shaft 2, as shown in FIG. 2, supports the three integrally provided impellers 4 so as to freely revolve.
In this embodiment, the rotary chambers 41 of the respective impellers 4 have the central shaft 2 respectively.
Looking at it, it is always located in the left half,
More specifically, for example, when the time reaches exactly 12 o'clock (position A in FIG. 2), the diameter wall 41A of the rotation chamber 41, which will be described later after being provided in the impeller 4, is just aligned in the windward direction. Has become.

The steering means 3 operates on the same principle as that of the weathercock, and the wind direction detecting means 31 provided at the upper end of the center shaft 2 rotates the center shaft 2 at any time in accordance with the wind direction. It has become. The lower end side of the central shaft 2 is interlocked with a rudder provided on the stern side through a connecting means (not shown) so that the bow is always operated so that the bow heads upwind. The wind direction detecting means 31 is also provided with a wind speed detecting means 62 (anemometer) (see FIG. 3), and an electric signal output according to the wind speed detected by the wind speed detecting means 62 will be described later. The blades 6 are output to the driving means 9 and the blades 6 are automatically adjusted to the optimum blade area corresponding to the wind speed.

Also, unlike this embodiment, as the steering means, the wind direction detecting means and the control section are connected to each other, and the wind direction with the highest frequency is selected from the wind directions detected by the wind direction detecting means in a unit time, for example, 10 minutes. Alternatively, the orientation of the hull that is the base body may be adjusted in the selected direction every 10 minutes. The unit time is not limited to 10 minutes, and may be 5 minutes or 2 or 3 minutes, for example.

The impeller 4 freely revolves around the center axis 2 which is immovable with respect to the hull 1. In this embodiment, three impellers are integrally connected by a connecting member. The inverted Y-shaped connecting member 42 shown in FIG.
Are held together at a central angle of 120 degrees and are integrally connected. Further, as shown in FIG. 4, the impeller 4 has a bearing 41B attached to the bottom of a rotation chamber 41 whose upper surface is formed in a substantially semicircular shape (center angle θ is 180 degrees). The rotating piece 5 is rotatably installed on the bearing 41B.
Further, although three impellers 4 are provided in this embodiment, the number of impellers 4 is not particularly limited to this, and four or more impellers may be provided, but in any case, they are integrally formed by the connecting member. It is necessary to keep them connected.

As shown in FIG. 4, the rotating piece 5 has a rotating chamber 4
It is rotatably attached via a rotary shaft 51A pivotally supported by a bearing 41B at the central portion of the diameter wall 41A in 1 and is located on the upper surface of the rotary piece 5 and directly above the rotary shaft 51A. The support 61 supporting the blades 6 is fixed in an upright state. The turning piece 5 of this embodiment is composed of a fan-shaped member having a central angle δ of 90 degrees, but is not particularly limited to this shape, and the central angle δ is 9, for example.
It may be smaller than 0 degrees.

The blades 6 are formed by using a thin sheet-shaped material such as aluminum or iron so that they can be alternately folded in a fan shape as shown in FIG. It is generally known from fluid dynamics knowledge that the wind speed increases as the height from the ground rises. Particularly, qualitatively, the wind speed received at a certain height portion of the blade 4 is v. The wind speed received at the upper part by a height h higher than this is v
If the wind speed v at the height h is
v = v. Since it is represented by h ^1/3 (the wind speed received by the blade 6 becomes higher as it goes upward), the blade 6 is formed so that the upper portion has a larger area than the lower portion.

Further, the blade 6 is adapted to give an orbital force to the impeller 4 when the rotating piece 5 to which the blade 6 is attached presses the diameter wall 41A when receiving the wind. By this, the impeller 4 revolves around the central axis 2, and as a result, the rotating plate 7 is rotated to operate the generator 8. In this embodiment, the electric power generated by the generator 8 is used as a driving means of an appropriate device for cleaning the lake where the hull 1 floats.

Further, the vane 6 changes the area of the portion which receives the wind by the driving means 9 (see FIG. 6) provided in the vicinity of the support body 61 to which it is attached or on the side of the rotating piece 5 to an optimum state. It is supposed to be adjusted. Therefore, the wind speed detecting means 62 is, as shown in FIG.
3 is connected to the input, and the output of the control unit 63 is connected to the driving means 9, and the wind speed detecting means 62 is connected.
Outputs a detection signal (for example, voltage) according to the wind speed,
The drive means 9 is controlled by a control signal output from the control unit 63 which receives the detection signal. The blade 6 rotates about the support 61, but as shown in FIG. 2, the blade 6 is longer on the longitudinal dimension side on the support 61 than on the short side. Since much wind is received, the longitudinal dimension side is always located on the lee side. The shape of the blade is not particularly limited to that of this embodiment. For example, as shown in FIG. 7, each side surface on both ends 60A side has a streamlined blade 6A, and FIG. The blade 6B having a rhombus shape shown in FIG. 6 or the rectangular blade 6C shown in FIG. 9 may be used.

The control section 63 uses a microprocessor or the like, and when the wind speed stored in the storage section 64 in advance is reached, the blades 6 are paid out or taken up. That is, when the wind speed detecting means 62 detects, for example, a wind of less than 13 m / sec, the blades 6 are fully opened, and at wind speeds of 13 m to 24 m / sec, a predetermined amount of the blades 6 are provided so as to have an area corresponding to the wind speed. With winding up
Further, when the speed exceeds 25 m / sec, the blade 6 is adjusted and controlled so as to be completely closed.

The drive means 9 is a motor 91 in FIG.
Of the pulley 92 attached to the output shaft 91A, the wire 93 having one end wound around the pulley 92, and the wire 93
Is constituted by a spring 95 stretched via a pulley 94 between the tip end side of the blade 6 having the other end fixed thereto and the tip end side of the guide member 65 described below. The blade 6 is extended and closed.

In the drive means 9 of this embodiment, the guide member 65 shown in FIG.
Is attached and the blade 6 is moved along a guide hole 65A provided on this one surface (the bottom surface of the upper guide member 65 and the top surface of the lower guide member 65). Guide member 65 shown in FIG.
It is hung at a fixed interval on a slidable moving body 65B provided inside. In addition, in this embodiment, the motor as the driving means is provided on the rotating piece near the installation position of the support,
Of course, the present invention is not limited to this, and may be installed on a guide member, for example.

The guide member 65 of this embodiment is shown in FIG.
As shown in 0, the structure is curved in one direction, and one side is formed longer than the other side with the support 61 as the center. Due to the difference in wind pressure described above, the lateral direction is always constant. As for the guide member 65 that is integral with the blade 6 pointing upwind,
The short side always points upwind.

Therefore, according to this embodiment, in FIG. 11, when the wind direction is blowing from top to bottom, every time each impeller 4 revolves, the position from the point A to the position E with respect to the central axis 2 is obtained. While, that is, half of the revolution period, the rotational force is applied to the rotating plate 7,
This impeller 4 revolves around the central axis 2 and at least one of them is given a rotational force (revolutionary force) from the blades 6, so that the impeller 4 is always rotated smoothly. Is obtained.

Further, according to this embodiment, even if the wind direction changes, the wind direction detecting means 31 and the steering means 3 adjust the direction of the hull 1 in accordance with the changed wind direction. And stable power generation operation can be obtained.
Further, since the blades 6 can be adjusted by the wind speed detecting means 62 and the control unit 63 to have an optimum area according to the wind condition at that time, for example, the blades 6 may be damaged due to gusts of wind or the hull 1 may be large. It can prevent tilting and sinking of the ship, and is very effective in terms of safety.

Further, according to this embodiment, the area is increased toward the upper side of the blade 6, and the effect that the wind energy can be taken in very efficiently can be obtained.

Next, another vertical wind turbine apparatus according to the present invention will be described with reference to FIG. In this embodiment, the same parts as those in the previous embodiment are designated by the same reference numerals to avoid redundant description.

In the vertical wind turbine of this embodiment, the impellers 4 are integrated by the lower rotary plate 7, and each impeller 4 is integrated.
Is configured to revolve around the guide member 43 fixed to the central shaft 2 which is erected from the hull 1. In the case of this embodiment, the steering means is installed in a part different from the central axis.

[0028]

As described above, according to the present invention, even if the wind direction changes, the front surface of the base body can always be kept constant, for example, the windward direction by the steering means, and each impeller can be At the time of revolving operation, the attitude of the blades with respect to the wind at the windward position is always constant,
As a result, for each impeller in the revolution motion, the angle of the blade with respect to the wind direction changes at each revolution position, but the angle of the blade with respect to the wind direction does not change for any impeller at the same revolution position. So
No matter how the direction of the wind changes, it is possible to apply a stable rotating force to the rotating plate at all times, in other words, the wind energy can be taken in as effectively as possible.

Further, according to the present invention, the direction of the blade and the area of the blade can be freely changed as compared with the conventional fixed blade, so that it is completely new and unique in design from the conventional one. There is an effect that can be realized.
