[0001] The present invention relates generally to wind power generators. More specifically, the present invention relates to a collective wind power generator including a plurality of small wind turbines.

[0002]

2. Description of the Related Art In recent years, wind power generation that does not pollute the environment has attracted attention. Wind power generation is a power generation method in which a windmill is rotated by wind and a rotational force is converted into electric energy. As a conventional wind power generator, an isolated wind power generator, a perch type wind power generator, and the like are known. The former is a device provided with a single windmill, and the latter has several small windmills attached to a perch-like member, and each windmill faces the wind by a vertical plate for steering. The apparatus is configured as described above.

[0003]

However, in order to obtain a large amount of electric power, it is necessary to install a large windmill in an isolated wind power generator, but it is difficult to manufacture a large windmill by using advanced technology. In addition to the need for power, the transfer from the factory to the installation site is not easy, and the construction period is long and the cost is high. On the other hand, in the perch type wind turbine generator, it is not necessary to manufacture a large wind turbine, but since the influence of the wind from the adjacent wind turbine is large, it is necessary to install each wind turbine at a certain interval, As a result, a large installation space is required and the cost is increased.

Accordingly, an object of the present invention is to overcome the above-mentioned problems of the conventional wind turbine generators, does not require advanced manufacturing techniques for manufacturing large wind turbines, does not require a large installation space, and is relatively simple. An object of the present invention is to provide a wind power generation device that can be manufactured in a short time and generates a large amount of power.

According to a first aspect of the present invention, there is provided a wind power generator, comprising: a pillar having a lower end embedded in a foundation;
A vertical frame rotatably disposed; a pair of horizontal frames mounted substantially horizontally below the vertical frame in a direction away from the vertical frames; and a plurality disposed above each horizontal frame Wind turbine unit, the wind turbine unit has a hexagonal or octagonal steel frame, a rotating shaft disposed substantially at the center of the steel frame, and a plurality of blades attached to the rotating shaft , The windmill units are combined so that the sides of the steel frame are adjacent to each other, and the lowermost windmill unit is supported by a horizontal frame.

A wind power generator according to a second aspect of the present invention is the wind turbine generator according to the first aspect of the present invention, wherein the front and rear surfaces of the steel frame of the wind turbine unit are covered with a wire mesh.

According to a third aspect of the present invention, there is provided a wind power generator according to the first or second aspect of the present invention, further comprising a wind direction anemometer disposed at an uppermost portion, and rotating the wind direction and wind speed value obtained by the wind direction anemometer. The motor is operated by converting the data into data of the direction and the movement amount, and the wind turbine unit is configured to always face the wind.

[0008]

Next, preferred embodiments of the present invention will be described with reference to the drawings. A wind power generator according to a preferred embodiment of the present invention, generally indicated by reference numeral 10 in FIG.
2, and a turning table 16 is attached to a lower portion of the supporting column 14, as shown in FIG.

A gantry 18 is mounted below the column 14 on which the swivel table 16 is mounted, and a motor 20 is mounted on the gantry 18. , A gear 20b.

On the other hand, around the support 14, the support 14 can be rotated by 360 ° in a horizontal plane around the support 14.
A vertical frame 22 is arranged. More specifically, as shown in FIG. 2, the lower end of the vertical frame 22 and the swivel table 16 are rotatably connected via a bearing 24, and a gear 22 a attached to the outer lower end of the vertical frame 22. And the gear 20b attached to the rotating shaft 20a of the motor 20 mesh with each other. As a result, when the motor 20 is operated, the rotational force is transmitted to the vertical frame 22 via the gear 22a, and the vertical frame 22 rotates in a horizontal plane around the support 14.

At the lower portion of the vertical frame 22 is mounted a pair of horizontal frames 24, 26 extending substantially horizontally away from the vertical frame 22.
The horizontal frames 24, 26 have substantially the same size, shape, and structure.

As shown in FIG. 1, a plurality of windmill units 28 are arranged above the horizontal frame 24, and a plurality of windmill units 28 are similarly arranged above the horizontal frame 26. I have.

As shown best in FIG. 3, the wind turbine unit 28 supports a hexagonal steel frame 28a, a rotating shaft 28b disposed substantially at the center of the steel frame 28a, and a rotating shaft 28b. , And three blades 28d attached to the rotating shaft 28b. Preferably, the front and rear surfaces of the steel frame 28a are covered with a wire mesh 28e to prevent the blade 28d from scattering due to a strong wind or an accident.

As shown in FIG. 1, the wind turbine units 28 are combined so that the sides of the steel frames 28a are adjacent to each other, thereby forming a honeycomb shape as a whole and forming a strong structure. Is done. The lowermost windmill unit 28 is supported by the horizontal frames 24 and 26. In order to firmly support the wind turbine unit 28, it is preferable to attach auxiliary frames 30, 32 extending vertically upward to the ends of the horizontal frames 24, 26.

The vertical frame 22 and the horizontal frame 2
4 and 26 and the auxiliary frames 30 and 32 are designed with a truss structure or the like so as to be able to resist various loads such as their own weight, the load of the windmill unit 28 and the like, wind load, seismic load and the like. I have.

FIG. 4 is a partial plan view showing the uppermost part of the wind power generator 10. At the top four circumferences of the vertical frame 22, anti-sway means 34 are attached so that the vertical frame 22 does not conflict with the column 14 when the wind power generator 10 shakes due to wind. The anti-sway means 34 includes an attachment 34a for mounting the anti-sway means 34 to the vertical frame 22, and the wheel 3 made of an elastic material such as rubber.
4b and a bracket 34c for rotatably attaching the wheel 34b to the attachment 34a. In addition,
The above configuration of the steady rest means 34 is exemplary,
Other configurations may be employed.

An anemometer 36 is arranged at the top of the wind power generator 10. The wind direction and the wind speed value obtained by the wind direction anemometer 36 are sent to the automatic turning follower 40 installed on the gantry 18. Then, the wind direction and the wind speed value are converted into data of the rotation direction and the movement amount in the automatic turning follower 40 and transmitted to a control device (not shown).
By operating the motor 20, the vertical frame 22 (accordingly,
The horizontal frames 24 and 26 and the windmill unit 28) are configured to always face the wind.

The present invention is not limited to the above embodiments of the invention, and various modifications can be made within the scope of the invention described in the claims. Needless to say, it is included in.

For example, in the above-described embodiment, the windmill unit 28 has the hexagonal steel frame 28a, but a windmill unit having an octagonal steel frame may be used. Further, the number and arrangement method of the wind turbine units 28 shown in FIG. 1 are merely examples, and different numbers of wind turbine units may be assembled by different arrangement methods. further,
In the above embodiment, the blade 28 of the wind turbine unit 28
The number of d is three, but may be another number such as four or five.
