Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a wind-hydro surface rolling body that rotates under the pressure of a fluid such as air or water, such as a windmill or a waterwheel. This relates to a vertical rotating axis type feng-shui surface rolling body that rotates in a constant direction even with respect to fluid flow.

C. Prior Art] Conventionally, as an example of a wind-hydraulic surface rolling body that rotates under the pressure of a fluid, such as a windmill or a water turbine, there is a paddle-type windmill that has a plurality of blades around a vertical rotation axis. In this case, there was a problem in that the resistance when the blade moved upwind was too large, reducing the efficiency to less than 10%.

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 pressure-receiving blades are arranged radially around the vertical rotation axis, and each pressure-receiving blade can change the elevation angle within an operating range of approximately 90° in a plane parallel to the rotation axis and orthogonal to the blade axis. It is constructed by being attached 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 a main part of a feng shui hexarotator according to Embodiment 1 of the present invention, and FIG. 2 is an overall perspective view showing the stationary state of FIG. 1. Figure 3 is an enlarged side sectional view of the main part of the vertical rotation shaft in Figure 1, Figure 4 is a side view of Figure 3, Figure 5 is a perspective view of Figure 3, and Figure 6 is the FIG. 3 is a plan view of the pressure receiving blade shown in FIG.

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 provided radially around the vertical rotating shaft 5 are each mounted so as to be swingable around the blade axis within an operating range of approximately 90°, as shown in FIG. ing.

That is, as shown in FIG. 3, each blade shaft 8 to which these pressure-receiving blades 6 are attached has a plurality of mounting bosses lO provided radially from the periphery of the vertical rotation shaft 5 and projecting at right angles to the vertical rotation shaft 5. It is rotatably mounted on the radial bearing 9A and thrust bearing 9B.

In addition, this blade shaft 8 is also provided with
As shown in the figure, a swinging bin 11 is fixedly installed, and this swinging pier 11 is connected to a swinging arm 1 fixed to a vertical rotating shaft 5.
The groove provided in 2 restricts the swinging within a range of approximately 90°.

In the Feng Shui six-rotator having the above configuration, as shown in FIGS. 1 and 2, each pressure-receiving blade 6 is parallel to the vertical rotation axis 5 in the pressure receiving state of the wind W, and is parallel to the vertical rotation axis 5 in the pressure-reducing state. In addition, in an intermediate state between receiving pressure and avoiding pressure, it takes an intermediate attitude with little resistance to the flow, and furthermore, in a stationary state, each pressure receiving blade 6 is rotated around the vertical rotation axis 5 as shown in FIG. The direction is parallel to.

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
．． About 8 degrees is ■ degree.

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.
3 and pressure receiving blades 6 installed radially from the periphery of a vertical rotating shaft 5 rotatably provided via a cantilever-shaped column 14, a radial bearing 15, and a radial thrust bearing 16 on the ground G below the water surface W, L. This example shows an example in which the water wheel is placed in the water wheel and rotated by the water flow F.
It has almost the same configuration and function as the first embodiment shown in the figures, 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 mounting boss 10 in the opposite direction to the first embodiment, but functionally they can be placed 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. 12, 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 six-rotator 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 turned clockwise by 90° from the parallel pressure-receiving state 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° as shown in the figure. It becomes.

〔Effect of the invention〕

As explained above, in the Feng Shui hexagonal body of the present invention, a plurality of pressure receiving blades are provided around the vertical rotation axis, and when the pressure receiving blades are in the pressure receiving state, they are approximately perpendicular to the fluid flow direction, that is, aligned with the vertical rotation axis. The pressure receiving blade rotates to a position opposite to the flow while maintaining a parallel attitude to the fluid flow, and then when rotating against the flow, the pressure receiving blade changes the phase by approximately 90 degrees and takes a position almost parallel to the fluid flow, that is, perpendicular. It rotates to a position in the forward direction of the flow while maintaining a right angle to the axis of rotation.
As a result, the fluid resistance of the pressure receiving blade can be reduced to zero in the section running against the flow, and the 90° phase shift of the pressure receiving blade 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.

In addition, in the feng shui six-rotator of the present invention, the pressure receiving blades provided radially around the vertical rotation axis are designed to swing independently, so the pressure receiving blades do not need to be an even number, but an odd number. The most appropriate number of pressure-receiving blades can be selected, and since a large number of mounting bosses can be provided radially at the same height of the vertical rotation axis, and a pressure-receiving blade can be installed on each of them, the most appropriate number of pressure-receiving blades can be selected. There is an advantage that the height of the Feng Shui hexagonal body can be kept low and that it can be made more compact.
