Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a damper type wind turbine equipped with damper blades that can be freely opened and closed.

[Conventional technology]

In general, wind turbines used for wind power generation and the like are desired to have high rotational efficiency and can obtain large rotational force with a small amount of wind power. A so-called "damper-type wind turbine" equipped with damper blades that can be opened and closed is known as one that satisfies this demand.

And as a conventional damper type windmill,
There is a vertical shaft dual damper wind turbine J described in No. 974.

As shown in Figures 15 and 16, this damper type windmill is
A rotatable vertical main shaft 50, upper and lower horizontal shafts 51 vertically attached to the vertical main shaft 50 at equal intervals, and a plurality of support rods 52 provided between the upper and lower horizontal shafts 51, It consists of a pair of concave damper blades 53 rotatably attached to a support rod 52 and having a flange 53a formed at the other end.
It comes into contact with and locks it.

When the wind blows in the W direction with respect to the damper type windmill as shown in FIG.
2 and is locked, the damper blade 53 is perpendicular to the direction of the wind, receives the wind pressure of the wind W directly, and rotates the entire damper blade 53 in the direction of .

On the other hand, the damper blade 53 on the other side (right side in the drawing)
It rotates in the direction S under the wind pressure of , and becomes horizontal with respect to the direction of the wind W. Therefore, the rotation blocking force of the damper blade t153 can be reduced.

[Problem to be solved by the invention]

However, in the conventional damper type wind turbine, a pair of damper blades 5
3 are not interlocked with each other, the opening and closing states are not always reversed, and the pair of left and right damper blades 53 may both receive wind, and in such a case, it is difficult to obtain efficient rotational force. I can't do it.

In view of the above-mentioned problems, the present invention provides a damper-type wind turbine that can constantly reverse the opening and closing states by interlocking a pair of damper blades, thereby significantly reducing the rotation blocking force caused by wind pressure and efficiently increasing the rotational force. The challenge is to provide.

[Means for Solving the Problems] In order to solve the above problems, the damper type wind turbine of the present invention has a rotatable vertical main shaft, a horizontal rod attached to the vertical main shaft in a vertical direction, and a horizontal rod attached to the horizontal rod. It consists of a pair of damper blades that can be freely opened and closed and are attached with the vertical main axis as an axis of symmetry, and a connecting rod that links the open and closed states of the damper blades to the opposite states.

Further, the damper blade may be configured to include a plurality of the pair of damper blades.

[Effect]

According to the damper type windmill of this invention, since it is provided with a connecting rod that links the open and closed states of the damper blades to the opposite states,
- When the example damper blade is in the open state, the other damper blade is always in the closed state.

Therefore, when the wind is blowing in a certain direction, the damper blades on one side, which are open, catch the wind and generate a rotational force, and the damper blades on the other side are closed, so
The rotation blocking force due to wind pressure is reduced.

The operation of the damper type wind turbine configured as described above will be explained.

As shown in Fig. 2, in this damper type windmill, when the damper blade C on one side (the left side in the drawing) is in the open state, the horizontal bar 5 attached to the upper flat plate 1b of the damper blade C is Since it has descended to the lowest position, the first connecting rod 7, which is pivoted to the second connecting rod 8 on the negative side, is in an upwardly rightward position. Since the second connecting rod 8, which is pivoted on the other side of the first connecting rod 7, is in an upper bound, the upper flat plate 1a on the other side is pushed by the horizontal rod 5, and the upper flat plate 1a on the other side (on the right side in the drawing) The damper blade C is always in the closed state. Conversely, if the damper blade C on the other side is in the open state, the damper blade M1c on the - side is in the closed state.

Note that guide parts 4 equipped with rollers are attached to both ends of the horizontal bar 5, and since the guide parts 4 move along the guide rods 3, the flat plate 1 can be opened and closed smoothly.

Therefore, as shown in FIG. 1, when the wind W is blowing in the direction of the arrow, the damper blade C on one side, which is in the open state, receives the wind pressure of the wind W and generates a rotational force. On the other hand, since the damper blade C on the other side is in the closed state, the rotation blocking force due to the wind pressure of the wind W is reduced, and the damper blade C as a whole rotates vigorously in the opposite direction due to the slight wind pressure. Then, when the damper blade C on the other side rotates to around the example, the wind W
In response to the wind pressure, the upper flat plate 1a rotates upward and the upper flat plate 1b rotates downward, resulting in an open state. At this time, the damper blade C rotated to the other side becomes closed due to the above-described action.

Further, an opening/closing plate 6 is attached to the inner base end of the upper and lower flat plates l so that it can be opened and closed, so that when the damper blade C is in the open state, it can be opened and closed as shown in FIG. 4(a). Board 6
will be in a closed state and will be completely exposed to the wind from between the upper and lower plates l. Therefore, the rotational force due to wind pressure can be further increased. Further, as shown in FIG. 4(b), when the damper blade C is in the closed state, the opening/closing plate 6 opens due to the wind pressure of the wind W, and the wind passes between the upper and lower flat plates 1. Therefore, the rotation blocking force due to wind pressure can be completely reduced.

Also, when using this invention as a windmill for power generation, etc.
In order to obtain stable power, a device is required to control the rotation speed of the wind turbine according to the wind force.

Therefore, for example, the first connecting rod 7, the shaft 7a, the contact part 10
It may be constructed so that it can be slid up and down integrally. As a result, the opening/closing angle of the damper blade C can be adjusted according to the wind force, and speed control jII becomes possible.

Note that since the guide portion 24 having rollers at both ends of the horizontal bar 25 is movably attached to the guide bar 23, the flat plate 21 can be opened and closed smoothly.

Regarding the effects of the damper type wind turbine of the second embodiment, see the first example.

Furthermore, in order to obtain more rotational force, a pair of damper blades may be installed in several stages above and below, and each may be configured to interlock with each other.

Furthermore, not only the first embodiment but also the second to fourth embodiments may be provided with a device that adjusts the opening/closing angle of the damper blades to control the rotational speed of the wind turbine.

Furthermore, this damper type windmill may be mounted on a ship and used as its power source.

Incidentally, since frictional noise or the like may be generated during the opening/closing operation of the damper blade C, a cushion material or the like may be used for soundproofing.

〔Effect of the invention〕

According to the damper type wind turbine of the present invention, excellent effects as described below are exhibited.

(1) Since the connecting rod is provided to link the open and closed states of the damper blades to the opposite states, when the damper blade in the example - is in the open state, the damper blade on the other side is in the closed state.
