Description

  The present invention relates to a vertical wind turbine, and in particular, a vertical wind turbine in which lift-type blades are arranged in multiple stages, and the phase in the plane of the blades is displaced vertically, and a wind turbine in which a plurality of the vertical wind turbines are arranged. It relates to a power generator.

  Conventionally, wind turbines of wind power generators generally use a horizontal axis propeller type, and a vertical axis wind turbine having a wind recovery rate of about 35% is not widely used because it is not practical. .

Since the vertical axis wind turbine has blades on both sides of the vertical main shaft, for example, when the left blade rotates by receiving wind, there is a problem that the right blade on the opposite side receives wind resistance.
Therefore, it is preferable to reduce the chord length (horizontal width) of the blade and increase the vertical dimension of the blade. However, if the vertical dimension of the blade is increased, the rigidity must be increased, and if the rigidity is increased. As a result, the weight increases and the rotation efficiency deteriorates. Further, the manufacturing cost is increased, and the workability of maintenance is deteriorated.

In addition, the wind power generator is affected by the wind condition, and there is a problem that a power transmission facility must be constructed in order to collect the generated power even in a place with a good wind condition.
An object of the present invention is to provide a vertical wind turbine capable of reducing the weight of the blade and increasing the wind receiving area of the blade, and a wind turbine generator provided with a plurality of the vertical wind turbines.

The present invention, in order to achieve the object by solving the above problems, the vertical dimension of the lift type blades as a small, smaller and lighter, yet which was arranged the lift type blades in multiple stages, the specific content It is as follows.

(6) the composite strut structure is surrounded by a plurality of struts, vertical axis wind turbine according shaft disposing portion which is disposed a vertical main axis in the center, in a planar continuous formed comprising the (5) .

(7) The vertical axis wind turbine according to any one of (1) to (6), wherein the lift type blade disposed in one rotating body is one .

(8) The vertical axis wind turbine according to any one of (1) to (6), wherein the number of lift-type blades disposed on one rotating body is two .

(9) The lift-type blades disposed in the respective shaft disposition portions are combined with objects of different sizes in accordance with the purpose of the entire windmill, as described in (5) or (6) above Vertical axis windmill.

  According to the present invention, the following effects can be obtained.

The vertical wind turbine of the invention described in the above (1) is a long vertical main shaft because the long vertical main shaft is supported by a plurality of upper and lower bearings supported by a plurality of support columns disposed around the long vertical main shaft. But it is not curved and has excellent rigidity. Between each bearing, a rotating body is disposed on each of the longitudinal main shafts, and each of the rotating bodies is provided with two longitudinal lift-type blades, with the inner surface during rotation facing the longitudinal main shaft, At the same level, the lift-type blade has a small resistance during rotation.
Also, lift type blades because they are disposed in multiple stages, and can be used to have small lift type blades in the vertical dimension, rigidity lightweight is sufficient. Even if small blades are used, the wind receiving area can be kept large as a whole because they are arranged in multiple stages.
Furthermore, since the plane positions of the upper and lower lift-type blades are arranged in different phases, the upper and lower lift-type blades correspond to the changing wind direction, and the rotational efficiency is improved.
By connecting the generator to the bottom of the vertical spindle, it can be an efficient wind turbine generator. Without using a generator, it can also be used for clean energy power of pumping machines, flour mills, etc.

In the vertical wind turbine according to the invention described in (2) above, since a plurality of rotating bodies are arranged on the vertical main shaft between the upper and lower bearings, for example, instead of lift type blades having a height of 3 m, 1.2 m the lift type blades by providing two stages, it is possible to increase the rigidity of the lift type blades, it is possible to increase the swept area of the lift type blades as a whole. By connecting the generator to the bottom of the vertical spindle, it can be an efficient wind turbine generator.

  The vertical wind turbine of the invention described in the above (3) is easy to assemble since the short vertical main shaft is connected in multiple stages instead of one vertical main shaft when the height increases.

  In the vertical wind turbine of the invention described in the above (4), the high voltage power transmission line support tower itself becomes the vertical wind turbine, so that it is easy to secure the installation location. When the generator is connected to the vertical main shaft, it becomes a wind power generator. When a large number of high-voltage transmission line support towers are used, large-capacity wind power can be generated while using a small windmill.

In the vertical wind turbine of the invention described in (5) above, a composite strut structure is formed, and a vertical main shaft is disposed in each of a plurality of shaft arrangement portions therein, and lift type blades are provided on the vertical main shaft. because it is arranged in multiple stages, the shaft torque is large, when allowed to connect the generator under each vertical main shaft, the wind power generation device having a large capacity complex pillar structure holds a number of small generators .
From this, since the composite strut structure can be constructed large and firmly, a large-capacity power generation of 100 kW / h to 1000 kW / h or the like is performed while using a vertical axis windmill that is said to have a poor wind recovery rate. it can be a wind turbine generator.

The vertical axis wind turbine of the invention described in (6), a shaft arrangement portion of the composite strut structure, substantially in the plane W, E, T, Y, U, I, O, A, S, F, H , K, L, Z, X, V, B, N, M, Δ, ☆, etc.
Thereby, even if the height of the composite strut structure is increased, the rigidity that does not collapse due to wind or earthquake can be easily maintained. Since the composite strut structure is assembled with steel materials in the vertical and horizontal directions, even if a thin steel material is used, the overall rigidity can be maintained, and the manufacturing cost can be reduced.
Moreover, since wind from all directions hits each axis arrangement part on average, a large number of vertical axis wind turbines can be arranged continuously in the horizontal direction, resulting in a composite wind turbine with good wind power recovery efficiency. when using, it is a wind turbine generator having a large power generation capacity of a few hundred kw / h.

In the vertical axis wind turbine of the invention described in (7), since there is one lift type blade disposed on one rotating body, even if a large chord length lift type blade is used, high speed rotation is possible. Is suitable. Further, since the upper and lower blades are arranged so as not to overlap in a plan view, the wind from either side can be used for rotation in response to the change in the wind direction.

In the vertical axis windmill of the invention described in (8), since there are two lift-type blades disposed on one rotating body, the rotation balance is excellent, and the phase in the plane of the blades is changed by using multiple stages. This is optimal for wind recovery. Further, since the upper and lower blades are arranged so as not to overlap in a plan view, the wind from either side can be used for rotation in response to the change in the wind direction.

In the vertical axis wind turbine of the invention described in (9) above, the lift type blades in the rotating body of each vertical main shaft disposed in each shaft disposition portion are not the same, but the lift type blades of different sizes but since it is combined with the purposes of the entire wind turbine, lift type blades suitable for high-speed wind, the lift type blades, etc. suitable for weak wind, to dispose in combination to suit wind conditions of the land be able to. As a result, any of the rotating bodies is rotating with respect to the direction of wind speed and the strength change, and the vertical axis wind turbine can obtain a total averaged rotational force.

Smaller and lighter with a lower vertical length of the lift type blades, the vertical main shaft, by disposing the multiple stages by changing the phase of the lifting force type blades, reduce wind resistance, the wind receiving area can correspond to the wind direction A large number of large wind turbines are combined into a large capacity wind power generator.

Embodiments of the present invention will be described with reference to the drawings. Figure 1 is a fragmentary front view of a wind turbine generator comprising a vertical axis wind turbine of the first embodiment according to the present invention, FIG. 2 is a sectional view along line A-A in FIG. 1.
In the figure, the wind power generator (1) uses a support (2) that constitutes a high-voltage power transmission line support tower, and a plurality of supports (2) and a plurality of lateral supports (2a) are framed. post internal surrounded by (2), as the axis disposing portion to dispose the vertical spindle (5) (B), the vertical main axis of ordinate windmill (3) to the shaft disposing portion (B) (2) Is arranged. Reference numeral (4) in the figure is a base. The column (2) can be a dedicated one.

The vertical wind turbine (3) is supported by the case body (3a) so that the longitudinal main shaft (5) is vertical and rotatable.
In the case body (3a), a generator (not shown) is disposed so as to be able to generate power with the rotational force of the longitudinal main shaft (5).
Vertical spindle of vertical axis wind turbine (3) (5), the central portion of the shaft arrangement portion surrounded by a plurality of struts (2) (B), are disposed through the cross member (2a) It is rotatably supported by a plurality of upper and lower bearings (6). A plurality of the horizontal supports (2a) are arranged on the support column (2) in multiple stages.

Between the opposing upper and lower bearings (6), the rotating body (7) is fixed in multiple stages to the longitudinal main shaft (5). In FIG. 1, the rotating body (7) is arranged in four stages, but it is optional such as 2 to 10 stages or more.
A support arm (7b) extending to the left and right is fixed to the shaft portion (7a) of each rotating body (7), and vertically long lift type blades (8) are respectively attached to the respective tip portions of the support arm (7b). These are arranged in parallel with the longitudinal main shaft (5) in between .

Lift type blades (8), as shown in FIG. 3, a substantially fish-shaped in cross-section, and the bulging portion on the inner side facing the longitudinal main axis (5) is formed. In addition, inclined portions (8a) that are curved toward the longitudinal main shaft (5 ) are formed at the upper and lower ends of the lift-type blade (8). During rotation therefore, wind lift type blades (8) is received is not be allowed to escape by the inclined portion (8a), the rotational force of the lifting vanes (8) is improved. In other words, wind hit the inner sides of the lift type blades (8), while applying a lift-type blade (8), the wind flowing up and down, is blocked by the inclined portion (8a), the wind pressure lifting vanes (8) will be pressed and the rotational force will be increased.

Further, in FIG. 2, the lift-type blade (8) in the rotating body (7) arranged in multiple stages is a two-blade positioned between the longitudinal main shaft (5) , and this lift-type blade (8) position in plan view is symmetrical, in the upper stage and the lower stage are disposed such that the phase is different. In FIG. 2, for example, lift type blades of the upper and lower stages (8) (8) is in a right angle cross. Further, FIG. 3 shows a case where the phase is displaced by 60 degrees in the upper, middle, and lower three stages.

If the number of lift-type blades (8) at the same level is the same for the same wind receiving area, the rotational speed is improved. This is because the lift-type blade (8) itself becomes a resistance during rotation.
However, even if the rotational speed is low, the axial torque of the longitudinal main shaft (5) becomes large if the entire wind receiving area of the lift-type blade (8) is large.

Therefore, it is suitable that one rotating body (7) is provided with two lift type blades (8), and these two lift type blades (8) are attached to the same longitudinal main shaft (5). It is optimal for wind recovery to be provided in multiple stages and to change the phase in the plane of the lift type blade (8). This is because the wind always changes direction, and the atmospheric pressure and the wind direction differ depending on the difference in height from the ground.

Thus, the rotating body in the longitudinal main axis (5) and (7) and arranged in multiple stages, a vertical main shaft by sandwiching a (5) two parallel lift type blade (8), the different phases in the vertical stage Therefore, even if the speed and direction of the wind are different between the upper and lower stages, any lift type blade (8) receives the wind, and the shaft rotation by the lift type blade (8) receives the wind of the higher wind speed. However, it leads the rotation of the longitudinal main spindle (5).

Further, without using the single long lifting vanes, by short lift type blades of vertical size arranged in the multi-stage lift type blades in one of the vertical main axis (5) of (8), Since the total wind receiving area can be increased, a large shaft torque can be obtained even when the wind speed is low.

In FIG. 1, reference numeral (9) denotes a capacitor, (10) denotes a transformer, and (11) denotes a power transmission line. When the lifting blade (8) receives wind and the rotating body (7) rotates, the vertical main shaft (5) rotates and is connected to the vertical main shaft (3a) in the case body (3a). A generator (not shown) is rotated to generate power.

The generated electricity is stored in the capacitor (9), transformed by the transformer (10), and transmitted to the destination by the transmission line (11).
That is, when using the struts (2) that constitute the high-voltage transmission line support tower, in a region with good wind conditions along the high-voltage transmission line, a large number of struts (2) of the high-voltage transmission line support tower It can be used for (3) and the wind power generator (1), and cost reduction can be achieved in the installation of the windmill and the power recovery by wind power generation.

  At the same time, the existing strut (2) in the high-voltage transmission line support tower can be used to collect the generated power. The vertical wind turbine (3) using the support (2) that constitutes the high-voltage transmission line support tower and the wind power generation system that transmits the generated power are easy to generate and recover in wind-powered areas. Can be implemented.

The wind power generator (1) of the second embodiment has the following advantages.
For example, as described above, when the height of the support (2) of the high-voltage transmission line support tower is high, when it can be used up to a considerable height, a plurality of vertical spindles are used rather than lengthening one longitudinal spindle (5). It may be better to use (5).
In particular, the width of the shaft arrangement part (B) surrounded by the plurality of support columns (2) is narrower at the upper part than at the lower part, so the turning radius of the rotating body (7) is inevitably small at the upper part. Become.

Therefore, when the vertical axis wind turbine (3) is arranged in multiple stages, for example, the vertical axis wind turbine (3) below has a vertical main shaft (5) with four stages of rotating bodies (7) and the rotating body (7). The vertical wind turbine (3) having a radius of 4 m and the vertical axis wind turbine (3) can be appropriately changed such that the vertical main shaft (5) has three stages of the rotary body (7) and the radius of the rotary body (7) is 3 m.
In particular, every 10 meters above the ground, the pressure differs by about 1 atm. Therefore, it may be better that the generators (not shown) in the case body (3a) of the vertical axis wind turbine (3) are vertically different.

FIG. 5 is a front view of an essential part of a wind turbine generator using a vertical axis wind turbine according to the third embodiment, and FIG. 6 is a plan view of the essential part. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the third embodiment, a plurality of vertical wind turbines (3) are assembled in the horizontal direction.

As shown in FIGS. 5 and 6, the wind turbine generator (1) includes a plurality of parallel struts (2) and a plurality of lateral supports (2a) arranged at regular intervals to form a composite strut structure ( 22) is formed, and a plurality of shaft arrangement portions (B) are provided thereon, and the vertical axis wind turbine (3) is provided in each shaft arrangement portion (B).

A generator (not shown) connected to the longitudinal main shaft (5) is disposed in the case body (3a) of each vertical wind turbine (3). Axis placement part (B) can be made continuous as possible. The continuous state can be continuous in a curved shape, a zigzag shape or the like in addition to the linear shape.

Continuous of the shaft disposing portion (B) can be without close contact, with the cross member of (2a) is interposed between mutually connected. Moreover, the height of each axis | shaft arrangement | positioning part (B) can be changed according to the certain topography, for example.

Vertical spindle vertical lengths of each axis arrangement portions each vertical axis wind turbine in (B) (3) (5) is by the upper and lower plurality of bearings (6), is rotatably supported. Each bearing (6) is supported by a plurality of upper and lower lateral supports (2a) installed between adjacent bearings (2). Between each of the upper and lower bearings (6), a rotating body (7) is disposed on the vertical main shaft (5).

Lifting-type blades (8) are respectively arranged symmetrically with the longitudinal main shaft (5) in the middle at the tips of the left and right support arms (7b) of each rotating body (7). . Two symmetrical lift type blades (8) in the upper and lower rotating bodies (7) are arranged with different phases in the plane so that the lift type blades (8) do not overlap each other in the upper and lower sides. Yes.

The wind turbine generator (1) using the vertical axis wind turbine (3) of Example 3 constructed in this way has a solid composite strut structure as a whole, even in typhoons and earthquakes, in places with good wind conditions. body (22) can build in a plan view, a plurality of vertical axis wind turbine (3), in the composite strut structure (22), a wind power generator comprising a composite wind turbine and disposed collectively (1).

Concomitantly, lift-type blades (8) can be arranged in multiple stages on each longitudinal wind turbine (3). Of course, a roof, a lightning rod, a solar power generation panel, and the like (not shown) can be disposed on the upper part of the composite column structure (22). A room (not shown) can be formed in the lower area. Furthermore, an advertisement surface on which an advertisement can be displayed can be formed at a position that does not affect the lift-type blade (8), for example, a part such as a bearing or a leg part. If it is necessary to display the advertisement and obtain the advertisement fee income, the maintenance cost of the composite strut structure (22) can be secured.

As a result, a solid composite strut structure (22) is constructed in a narrow place with good wind conditions, and small vertical wind turbines (3) are arranged on a number of shaft arrangement parts (B). A large wind receiving area can be secured.
Even if the power generation capacity of each generator in each vertical wind turbine (3) is as small as 5 kW / h, for example, if there are 100 vertical wind turbines (3) in one composite strut structure (22) , A wind power generator (1) having a large power generation capacity of 500 kw / h can be configured.

That is, a large-capacity wind power generator (1) can be obtained by assembling a composite vertical column wind turbine (3) on the composite strut structure (22) to form a composite. Since this composite strut structure (22) uses a vertical axis wind turbine (3) instead of a propeller type wind turbine, a large number can be assembled, and it is said that the wind recovery rate is inferior. A large number of axial wind turbines can also be assembled in this manner, whereby a wind power generator (1) that generates a large amount of power with a single power generation facility can be obtained.

7, was used vertical axis wind turbine of an embodiment 4 of the present invention, it is a schematic plan view of a wind turbine generator. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In Example 4, a plurality of struts (2) axis arrangement portion formed by (B), to form a composite pillar structure that has a plurality of continuous back and forth horizontally in plan view (22), each shaft disposed A vertical wind turbine (3) is provided for each part (B).

According to the plurality of struts (2), the axial arrangement portion of a composite strut structure (22) to (B), in the case where which a plurality formed in the longitudinal and lateral in plane, it is conceivable to as wind is deteriorated, the shaft Increasing the area of the disposition portion (B) and increasing the degree of clearance solves the problem.
In FIG. 7, the shaft disposing portion (B) is continuously arranged in a square ring shape. The annular shaft arrangement portion (B) can be formed in a circular shape or a triangular shape according to the terrain to be installed. In this aspect, it can be easily and robust against typhoons and earthquakes.

8, was used vertical axis wind turbine of an embodiment 5 of the present invention, it is a schematic plan view of a wind turbine generator. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
Wind turbine generator (1) in the fifth embodiment, the shaft arrangement portion of the composite strut structure (22) to (B), and was continuously formed into a substantially Y-shaped in plan view.
By adopting such a shape, the rigidity can be maintained stably against a typhoon or an earthquake even as a high-rise building. Moreover, the wind from all directions can be allowed to pass through each shaft arrangement part (B) on average.

In the embodiment shown in FIG. 5 and subsequent figures, the size of the lift-type blade (8), the number of lift-type blades (8) at the same level, and the like can be changed in the vertical direction and the horizontal direction.

That is, depending on the size and number of the lift-type blades (8), there is a difference between a case suitable for high-speed wind and a case where it rotates even in low wind.
Therefore, when there are a large number of shaft arrangement parts (B) in the large composite strut structure (22), the vertical type wind turbine (3) has a difference rather than the same lift type blade (8), For wind changes, it may be preferable in terms of which one is spinning. In this respect, the vertical wind turbine (3) suitable for high-speed wind and the vertical common wind turbine (3) suitable for low wind can be combined in the range of the greatest common divisor.
