Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a feng shui hexarotator that rotates under the pressure of fluid such as air or water, such as a windmill or a water turbine. This relates to a vertical rotating shaft type hexagonal Feng Shui body that rotates in a constant direction even with respect to the flow.

[Prior art]

Conventionally, an example of a feng shui hexagonal body that rotates under the pressure of fluid, such as a windmill or waterwheel, is a paddle-type windmill that has a plurality of blades around a vertical axis of rotation. There was a problem in that the resistance when moving upward was too large and the efficiency decreased to 10% or less.

In addition, the Savonius type wind turbine, which has two semi-cylindrical blades around a vertical rotation axis, has the advantage of having a small starting torque and a large rotating torque, but its efficiency is limited to 15%. Furthermore, in the case of a Darrieus-type wind turbine that has multiple special airfoil-shaped blades around a vertical rotation axis,
Although the efficiency can be increased to about 35%, there is a problem in that it requires a large starting torque and is difficult to start at low wind speeds.

Further, in the above-mentioned Savonius type and Darius type wind turbines, it is necessary to increase the vertical height of each blade to some extent, and there is a problem in that it is difficult to make the wind turbine compact.

[Purpose of the invention]

The present invention was made in order to solve the above-mentioned conventional problems, and an object of the present invention is to provide a compact Feng Shui hexagonal body that has high efficiency, low starting torque, and extremely large rotational torque. It is said that

[Structure of the invention]

The Feng Shui hexagonal body of the present invention for achieving the above object is as follows:
A plurality of pairs of pressure-receiving blades are arranged radially around the vertical rotation axis, and the phase angle facing each other is maintained at approximately 90 degrees, and each pair of pressure-receiving blades can change the elevation angle while maintaining the above-mentioned phase angle. It is constructed by being mounted so that it can swing freely.

[Example] The present invention will be described in detail below with reference to the drawings. Fig. 1 is a perspective view of the main part of a feng shui hexarotator according to Embodiment 1 of the present invention, and Fig. 2 shows the stationary state of Fig. 1. FIG. 3 is an enlarged side sectional view of the main part of the vertical rotation shaft in FIG. 1, and FIG.
5 is a perspective view of FIG. 3, FIG. 6 is a plan view of the pressure receiving blade of FIG. 1, and FIG. 7 is a front view of the arrangement of the Feng Shui hexagonal body of FIG. 1.

First, the Feng Shui hexagonal body 1 of the present invention shown in FIG.
A plurality of pressure receiving blades 6 are provided radially around the upper part of a vertical rotating shaft 5 which is rotatably supported via a radial bearing 3 and a thrust bearing 4, and a generator 7 is provided at the lower end of the vertical rotating shaft 5. It is used in power generation equipment.

Next, the pressure-receiving blades 6 radially provided around the vertical rotation shaft 5 are arranged so that the phase angles facing each other are maintained at approximately 90° as shown in FIGS. 1 and 2.
, A' and B, B' are arranged.

Therefore, as shown in Fig. 3, these pressure receiving blades 6
Each pair of shafts 8 to which the shafts 8 are attached pass through the vertical rotation shaft 5 at right angles, and are attached to both ends of a sleeve boss 10 rotatably provided by a radial bearing 9.

Further, as shown in FIGS. 3, 4, and 5, a swing pin 11 is fixed to the sleeve boss 10.
This swing pin 11 is restricted to swing within a range of approximately 90° by a groove provided in a swing arm 12 fixed to the vertical rotation shaft 5.

That is, the swing pin 11 and swing arm 12 allow each pair of pressure receiving blades 6 to swing freely within a range of approximately 90° while maintaining the phase angle of 90°. There is.

In the Feng Shui hexagonal body constructed as described above, as shown in FIGS. 1 and 7, each pressure-receiving blade 6 is parallel to the vertical rotation axis 5 in the pressure receiving state of the wind W, and perpendicular to the vertical rotation axis 5 in the pressure-reducing state. In addition, since the blades on the opposite side of each blade in the pressure receiving and pressure relief states maintain a phase angle of 90°, they will relatively assume the pressure relief and pressure receiving states, respectively. Become. In the stationary state, it forms an angle of 45° downward with respect to the vertical rotation axis 5, as shown in FIG.

In this embodiment 1, as shown in FIG. 6, by arranging the pressure receiving blades 6 on both sides of the blade shaft 8 in sections a and b, the influence of the blade weight is reduced, and the pressure receiving blade 6 on the escape pressure side is It reacts sharply even to low-speed fluids, and tends to have zero flow pressure resistance in the horizontal state perpendicular to the vertical rotation axis 5. As a result, it can easily rotate against low-speed fluids, but in this case. The distribution ratio a/b of the pressure receiving blade 6 is 0
．． The upper limit is about 8.

In this case, the b side of the blade has a larger area and weight than the a side, so in the vacuum state, the b side is located at the rear of the fluid flow, and the a side is located at the front. Also, in the pressure receiving state, b
The side is located at the bottom, and the side a is located at the top.

Next, the Feng Shui hexagonal body of Example 2 shown in FIGS.
Pressure-receiving blades 6 are installed radially from the periphery of a vertical rotating shaft 5, which is rotatably provided on a column 14 provided in a cantilever shape on the ground G, via a radial bearing 15 and a radial thrust bearing 16, under the water surface W, L. This is an example in which it is used as a water wheel, which is placed in a water wheel and rotated by water flow F, and has almost the same configuration and function as Example 1 shown in Fig. 1, and the same parts are indicated by the same part numbers. .

Therefore, in this second embodiment, the swing pin 11 and the swing arm 12 are provided above the sleeve boss 10, and the direction is opposite to that of the first embodiment, but functionally they may be in either direction. In the second embodiment, the pressure receiving blade 6 is provided only on one side of the blade shaft 8 as shown in FIG. 13, but the pressure receiving blade 6 is also divided into a and b as in the first embodiment shown in FIG. You may use what you have placed.

In addition, in the feng shui hexarotator of Examples 1 and 2 described above, the vertical rotation axis 5 rotates to the left, and when the operating angle of the pressure receiving blade 6 is set to 90 degrees, the vertical rotation axis 5 rotates to the left. When the pressure-receiving blade 6 is changed clockwise from the parallel pressure-receiving state by 90" and the pressure-receiving state is perpendicular to the vertical rotation axis 5, the phase angle between the swing pin 11 and the pressure-receiving blade 6 is 45 degrees as shown in the figure. It becomes.

〔Effect of the invention〕

As explained above, in the feng shui hexarotator of the present invention, a plurality of pairs of pressure receiving blades are provided around the vertical rotation axis, and when the pressure receiving blades are in the pressure receiving state, the blades rotate vertically at almost right angles to the fluid flow direction. It rotates to a position opposite to the flow while maintaining a posture parallel to the axis, and then when rotating against the flow, the pressure-receiving blade changes its phase by approximately 90 degrees and takes a position almost parallel to the fluid flow. In other words, since it rotates to a position in the forward direction of the flow while maintaining a right angle to the vertical axis of rotation, the fluid resistance of the pressure receiving blade can be reduced to zero in the section that goes against the flow, and this pressure receiving blade The 90° phase shift of is automatically performed alternately every 180° rotation.

Therefore, the feng shui hexarotator of the present invention has very high efficiency, low starting torque, and extremely large rotational torque, and its height can be reduced, and the resistance of the blades toward the flow can be reduced. Since there is no need for a shielding plate or the like to block the flow for reduction, there is an advantage that it can be formed more compactly.

The feng shui hexarotator of the present invention has a plurality of pairs of pressure-receiving blades radially provided around the vertical rotation axis, with the opposing phase angle maintained at approximately 90", and each pair has a Since the pressure receiving blade is designed to swing,
There is no risk of thrust being applied to the blade shaft due to the centrifugal force that accompanies the rotation of the pressure-receiving blade (as a result, there is less mechanical loss and efficiency can be further increased, and there is no need to use a thrust bearing on the blade shaft, which improves the structure. It has the advantage of being easier.
