A wind power generation system in which wind turbines are arranged and the electricity generated by the power generators of the vertical wind turbines is collected and collected in one place.

  The present invention has the following effects.

(1) The vertical wind turbine of the invention described in claim 1 is long 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 longitudinal main shaft. Even the vertical spindle is not curved and has excellent rigidity. Between each bearing, a rotating body is disposed on each longitudinal main shaft, and each rotating body is provided with two vertically long blades, with the left side facing the longitudinal main shaft, and at the same level, the blades are in rotation. Resistance is small.
In addition, since the blades are arranged in multiple stages, blades having a short height can be used, and the rigidity is sufficient even if the weight is light. Even if small blades are used, since they are arranged in multiple stages, the entire wind receiving area can be kept large.
Since the plane positions of the upper and lower blades are arranged at different phases in the upper and lower directions, either the upper or lower blade corresponds to the changing wind direction, and the rotation efficiency is improved.
By connecting a generator to the lower part of the vertical main shaft, an efficient wind power generator can be obtained. Moreover, it can use for clean energy motive power, such as a pumping machine and a mill, without using a generator.

  (2) In the vertical wind turbine of the invention described in claim 2, since a plurality of rotating bodies are arranged on the vertical main shaft between the upper and lower bearings, for example, instead of a blade having a height of 3 m, a 1.2 m By arranging the blades in two stages, the rigidity of the blades can be increased, and the wind receiving area of the blades can be increased as a whole. By connecting a generator to the lower part of the vertical main shaft, an efficient wind power generator can be obtained.

  (3) The vertical wind turbine of the invention described in claim 3 has a single main portion in which the vertical main shafts are arranged in multiple stages, so that the height of one vertical main shaft can be shortened. . In addition, a thin vertical spindle can be used.

  (4) In the vertical axis wind turbine according to the invention described in claim 4, since the high voltage power transmission line supporting tower itself becomes the vertical axis wind turbine, 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.

(5) In the vertical axis wind turbine according to the invention described in claim 5, a composite strut structure is formed, and a longitudinal main shaft is disposed in each of a plurality of disposed portions, and a plurality of blades are provided on the longitudinal main shaft. Therefore, when the generator is connected under each vertical main shaft, the composite strut structure becomes a large-capacity wind generator holding a large 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. Can be a wind power generator.

  (6) Since the longitudinal main shaft is arranged in multiple stages in the same arrangement portion in the plane of the composite strut structure, the vertical wind turbine according to the invention described in claim 6 can increase the height of the composite strut structure. By setting it high and arranging the vertical main shafts in multiple stages to make the rotating body in multiple stages, it becomes a wind turbine that can efficiently collect wind power in a region with good wind conditions, and can be a wind power generator.

(7) In the vertical axis wind turbine of the invention described in claim 7, the arrangement portion of the composite strut structure is substantially W, E, T, Y, U, I, O, A, S, F, It can be made to continue in the shape selected from H, K, L, Z, X, V, B, N, M, Δ, □, and ☆.
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.
In addition, wind from all directions hits each installation section on average, so a large number of vertical wind turbines can be installed continuously in the horizontal direction, resulting in a composite wind turbine with good wind recovery efficiency and used for wind power generators. When doing, it can be set as the wind power generator which has a large power generation capacity of several hundred kw / h.

  (8) In the vertical wind turbine according to the invention described in claim 8, since the vertical main shafts arranged in the respective arrangement portions are connected so as to be synchronized by the synchronous transmission means, the wind hits well. The rotational force of the rotating body at the position rotates the rotating body at the position where the wind is difficult to hit, and the vertical main shaft of the entire wind turbine rotates synchronously at the beginning of rotation. Therefore, the axial torque of the entire vertical main shaft is 1 You can also gather in places.

  (9) The vertical axis wind turbine of the invention described in claim 9 uses one blade at the same level, and therefore has no wind resistance on the opposite side of the main shaft and is suitable for high-speed rotation. Even with a single blade, the front-rear width can be increased, so the wind receiving area is not reduced. In addition, since the upper and lower blades are arranged so as not to overlap with each other on the plane, the wind from either side can be used for rotation in response to changes in the wind direction.

  (10) In the vertical axis wind turbine according to the invention described in claim 10, the blades in the rotating bodies of the vertical main shafts arranged in the respective arrangement portions are not the same but different in purpose. Therefore, blades suitable for high-speed wind, blades suitable for weak wind, and the like can be combined and disposed so as to suit the local wind conditions. 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.

  (11) The vertical axis wind turbine according to the invention described in claim 11 is formed with an advertising surface on the outer surface of the vertical column wind turbine support so that the advertisement can be displayed at a position where there is no influence of the passing wind on the blades. Therefore, the maintenance cost of the support can be compensated with the advertisement fee obtained by displaying the advertisement on the advertisement surface.

  (12) The wind power generation system according to the invention described in claim 12 uses a plurality of high-voltage power transmission line supporting towers, and a vertical axis wind turbine is provided in each of the towers. Therefore, the total number of steel towers on which the vertical axis wind turbines are arranged becomes one wind power generator, and a large amount of wind power can be generated in total.

(13) In the wind power generation system according to the invention described in claim 13, one arrangement part is formed by a plurality of support columns, and a plurality of each installation part is continuously formed on a plane to form a composite support column structure. Since the vertical wind turbines that respectively hold the power generators are disposed in the respective placement portions, the composite strut structure can be firmly constructed in a place with good wind conditions.
By arranging a vertical axis wind turbine in each of a plurality of arrangement portions, even if the vertical axis wind turbine is small and its generated power is small, if the generated power is collected in one place, 1 The composite strut structure is a large-capacity wind power generator.

  Reduced blade height by reducing the height of the blades, and by arranging two blades on the vertical main shaft in multiple stages by changing the phase of the blades, wind resistance can be reduced, the wind direction can be accommodated, and the wind receiving area is large It becomes. A large number of wind turbines are combined into a large-capacity wind power generator.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an essential part of a wind power generator using a vertical wind turbine according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG.
In the figure, the wind power generator (1) uses the column (2) that constitutes the high-voltage power transmission line support tower, and the vertical main shaft (5) is arranged inside the plurality of columns (2). As the disposing portion (B), the longitudinal main shaft (2) of the vertical wind turbine (3) is disposed in the disposing portion (B). Reference numeral (4) in the figure is a base. As for the said support | pillar (2), an exclusive support | pillar can be erected naturally.

In the vertical axis wind turbine (3), the longitudinal main shaft (5) is vertically and rotatably supported by the case body (3a).
In the case body (3a), for example, a power generator (not shown) is disposed so as to be able to generate power with the rotational force of the longitudinal main shaft (5).
The vertical main shaft (5) of the vertical axis wind turbine (3) has a plurality of upper and lower parts arranged at the center of the arrangement part (B) surrounded by the plurality of support posts (2) via the support (2a). The bearing (6) is rotatably supported. A plurality of the supports (2a) are arranged in multiple stages on the support (2).

Between the upper and lower bearings (6), the rotary body (7) is fixed in multiple stages to the vertical 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 blades (8) are respectively attached to the respective distal end portions of the support arm (7b). The left side surface is arranged to face the vertical main shaft (5).

  As shown in FIG. 3, the blade (8) has a substantially fish-like cross section and a bulge on the left side. In addition, the blade (8) is formed with an inclined portion (8a) in which the top and bottom tips are curved to the left (inside). During rotation, the wind received by the blade (8) is not released by the inclined portion (8a), and the rotational force of the blade (8) is improved. That is, the wind hitting the left side of the blade (8) tries to escape vertically and horizontally while pressing the blade (8), but the wind flowing up and down is blocked by this inclined portion (8a), Will press the blade (8) and increase the rotational force.

  In FIG. 2, the blades (8) in the rotating body (7) arranged in multiple stages are two blades on the left and right, and the positions of the blades (8) in the plane are symmetrical, and the phase between the top and bottom is They are arranged differently. For example, in FIG. 2, there is a right-angle crossing at the top and bottom. Further, FIG. 3 shows that the phase is displaced by 60 degrees in the upper, middle and lower directions.

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

  Therefore, two blades are suitable for one rotating body (7), and the two blades are arranged on the same longitudinal main shaft (5) to change the phase in the plane of the blade (8). However, it is ideal for wind recovery. Wind always changes direction, and atmospheric pressure and wind direction differ depending on the difference in height from the ground.

  Therefore, the rotating body (7) is arranged in multiple stages on the vertical main shaft (5), and the two-symmetrical blades (8) have different phases up and down, so the wind speed and direction are different up and down. Also, one of the blades (8) receives the wind, and the shaft rotation by the blade (8) receiving the wind having the higher wind speed leads the rotation of the longitudinal main shaft (5).

  Also, increase the total wind receiving area of the blade (8) in one longitudinal main shaft (5) by arranging short blades in multiple stages without using one long blade. Therefore, the shaft torque can be increased even when the wind speed is low.

  In FIG. 1, symbol (9) is a capacitor, (10) is a transformer, and (11) is a power transmission line. When the rotating body (7) rotates in response to wind on the blades (8), the vertical main shaft (5) rotates and is arranged in the case body (3a) connected to the vertical main shaft (3a). A power 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 wind turbine installation and power recovery by wind power generation.

  At the same time, the existing strut (2) of the high-voltage transmission line support tower can be used to collect the generated power. This wind power generation system that installs the vertical axis wind turbine (3) and uses the prop (2) that constitutes the high-voltage power transmission line support tower and transmits power easily implements wind power generation and power recovery in inconvenient areas can do.

FIG. 4 is a front view of an essential part of a wind power generator using a vertical axis wind turbine, showing a second embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In this second embodiment, a single vertical section (B) in which a plurality of vertical axis wind turbines (3) each having blades (8) arranged in multiple stages on a longitudinal main shaft (5) are surrounded by struts (2). Further, they are arranged in multiple stages.

The wind power generator (1) of the second embodiment has the following advantages.
For example, as described above, when the height of the supporting tower (2) of the high-voltage power transmission line support tower is high and 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).
Particularly, since the upper portion of the arrangement portion (B) surrounded by the plurality of columns (2) is narrower than the lower portion, the rotating radius of the rotating body (7) is inevitably smaller at the upper portion. .

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, since it is different by 1 atm when it exceeds 10 m above the ground, it may be better that generators (not shown) in the case body (3a) of the vertical 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 a 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 left, right, front, back, top and bottom.

  As shown in FIGS. 5 and 6, the wind power generator (1) includes a plurality of struts (2) arranged at regular intervals to form a composite strut structure (22). The installation part (B) is provided, and the vertical axis wind turbine (3) is provided in each installation part (B).

  A generator (not shown) is disposed in the case body (3a) of each vertical wind turbine (3), connected to the longitudinal main shaft (5). This arrangement | positioning part (B) can be continued as much as possible. The continuous state can be continued in a curved or zigzag shape in addition to a straight line.

  The arrangement of the arrangement portions (B) can be connected with the support (2a) interposed therebetween without being in close contact with each other. Moreover, the height of each arrangement | positioning part (B) can be changed according to the certain topography, for example.

  Each longitudinal wind turbine (3) in each arrangement portion (B) has a long longitudinal main shaft (5) rotatably supported by a plurality of upper and lower bearings (6). Each bearing (6) is supported by a plurality of upper and lower supports (2a) installed between adjacent bearing columns (2). Between each of the upper and lower bearings (6), a rotating body (7) is disposed on the vertical main shaft (5).

  At the tips of the left and right support arms (7b) of each rotating body (7), vertically long blades (8) are arranged symmetrically with the left side facing the longitudinal main axis (5). ing. The two symmetrical left and right blades (8) of the upper and lower rotating bodies (7) are arranged with different phases in the plane so that the blades (8) do not overlap each other vertically.

  The wind power generator (1) using the vertical axis wind turbine of this third embodiment constructed as described above is a composite strut structure that is strong as a whole even in typhoons and earthquakes in places with good wind conditions. (22) can be constructed, and in the plane, a plurality of vertical wind turbines (3) are arranged together in the composite strut structure (22) to be a wind power generator composed of a composite wind turbine. Can do.

  Along with this, it is possible to arrange the blades (8) in multiple stages on each longitudinal wind turbine (3). Of course, a roof, a lightning rod, a solar power generation panel, etc. (not shown) can be disposed on the upper part of the composite strut 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 where the blade (8) is not affected by the passing air, for example, a part having a bearing or the like, a leg portion or the like. When the advertisement is displayed and there is an advertising fee income, the maintenance cost of the composite strut structure (22) can be secured.

In this way, a solid composite strut structure (22) is constructed in a narrow place with good wind conditions, and a large number of small vertical wind turbines (3) are arranged in a number of arrangement parts (B). A large wind receiving area can be obtained.
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) The 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 can be obtained by assembling a composite vertical column wind turbine (3) on the composite strut structure (22) to form a composite. This composite strut structure (22) is not a propeller type windmill but uses a vertical axis windmill, so it is possible to gather a large number, and the vertical axis windmill which is said to be inferior in wind power recovery is also used. Thus, by combining a large number in a complex manner, it has become possible to make a wind power generator that generates a large amount of power with one power generation facility.

FIG. 7 is a plan view of an essential part of a wind power generator using a vertical wind turbine according to a fourth embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In this 4th Example, the composite support | pillar structure body (22) which made the arrangement | positioning part (B) formed of the some support | pillar (2) continuous in the left and right and back and front on the plane is formed, A vertical wind turbine (3) is arranged for each B).

If a plurality of arrangement portions (B) in the composite strut structure (22) are formed by the plurality of struts (2) on the left and right and back and forth, it is possible that the wind passage will deteriorate, Increasing the area of the part (B) and increasing the degree of clearance solves the problem.
In FIG. 7, the arrangement portion (B) is continuously arranged in a square ring shape. The annular arrangement portion (B) is formed according to the terrain to be installed, whether circular or triangular. This aspect can be easily made robust against typhoons and earthquakes.

FIG. 8 is a plan view of an essential part of a wind power generator using a vertical wind turbine according to a fifth embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the wind power generator (1) in the fifth embodiment, the arrangement portion (B) of the composite strut structure (22) is continuously formed in a substantially Y shape on a plane.
With this shape, even high-rise ones can stably maintain rigidity against typhoons and earthquakes. Moreover, the wind from all directions can also pass through each arrangement | positioning part (B) on average.

The planar shape of the composite strut structure (22) is W, E, T, Y, U, I, O, A, S, F, H, K, L, Z, X, V, B, N, It can be M, Δ, □, ☆, etc. This shape can be easily made strong against typhoons and earthquakes.
In this way, the vertical axis wind turbine (3) is arranged in each arrangement portion (B) of the composite strut structure (22), and the wind turbine generator (1) as a whole makes it possible to make a small vertical axis wind turbine. (3) can be used.

  Therefore, it is not necessary to enlarge the blade (8), and the use of a lightweight blade is excellent in rigidity, workability, and cost. Also, wind resistance at the same level can be achieved by arranging two blades (8) in multiple stages on one longitudinal main shaft (5) and the positions of the upper and lower blades (8) with different phases on a plane. In addition, it is possible to efficiently collect wind in response to changes in wind direction.

FIG. 9 is a plan view of an essential part of a wind power generator using a vertical wind turbine according to a sixth embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the wind power generator (1) according to the sixth embodiment, the vertical main shaft (5) of each vertical wind turbine (3) in the arrangement part (B) of the composite strut structure (22) is synchronized with the transmission means (5a). For example, the rotation is synchronized with a gear, a chain, or the like.

As a result, when the vertical axis windmill in the portion with good wind starts to rotate, the wind turbine in the portion with weak wind permeation is rotated in synchronization with each other, so that the initial rotation starts simultaneously as a whole.
Further, in the plurality of arrangement portions (B) in the composite strut structure (22), a large generator is connected to only one vertical wind turbine, and the rotational force of the other vertical wind turbine (3) is A large generator can be rotated by synchronous transmission by the synchronous transmission means (5a). This synchronous transmission means (5a) can also be used in the embodiments shown in FIG.

In FIG. 9, the blades (8) at the same level are shown as one blade in one rotating body (7), and the blades (8) in the plane are arranged so that the blades (8) do not overlap each other vertically. ) Is displaced by 90 degrees.
Also in the horizontal direction, the direction of the blade (8) of the adjacent vertical main shaft (5) is displaced as shown in the figure. The displacement angle of the phase of these blades (8) is not limited to this embodiment.

  The single blade (8) in FIG. 9 can be used for any of the previous examples. In the embodiment shown in FIG. 5 and subsequent figures, the size of the blade (8), the number of blades (8) at the same level, and the like can be changed in the vertical and horizontal directions.

That is, depending on the size and number of 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 arrangement parts (B) in the large composite strut structure (22), the difference in the wind changes when the blade (8) of the vertical wind turbine (3) is the same, rather than the same. May be preferable in terms of which one is turning. In that respect, it can be combined in the range of the greatest common divisor of the windmill (3) suitable for high-speed winds and the windmill (3) suitable for weak winds.

  The present invention is not limited to the above-described embodiments, and the design can be changed as appropriate in accordance with the purpose. For example, the composite strut structure (22) can be formed into a front table shape in a pseudo manner. In each vertical wind turbine, a flexible shaft can be connected to the lower part of the vertical main shaft (5). The arrangement portion (B) can also be formed by using a cellular phone, a microwave antenna support, or the like. The arrangement portion (B) can be formed into a unit, and a plurality of the arrangement portions (B) can be connected to form a composite strut structure (22) having an arbitrary shape. Moreover, in order to prevent the damage member from scattering due to a typhoon or the like, a net or the like can be stretched on the support column (2).

  In addition, in FIG. 1, when a generator (not shown) is connected to the longitudinal main shaft (5) and arranged on the case body (3a), the whole becomes the wind power generator (1), but the generator is not used. Thus, for example, when a pumping machine, a milling machine, or the like is made to correspond to the case body (3a), since the whole indicated by the symbol (1) is a vertical axis wind turbine, the symbol is replaced. The same applies to the configuration in FIG.

Since the vertical axis windmill of this invention arrange | positions a blade | wing so that it may not overlap on upper and lower sides, it can collect | recover wind power efficiently with a small blade | wing, and can also utilize high-rise wind power.
Thereby, it can utilize for the wind power generator in which large-capacity electric power generation by a group of small windmills is possible.

It is a principal part front view of the wind power generator which uses the vertical axis | shaft windmill of 1st Example of this invention.
