[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generator,
In particular, the present invention relates to a wind power generator improved to simplify its handling.

[0002]

2. Description of the Related Art Wind power generation is attracting attention as a leading system for pollution-free power generation. In this wind power generation, when focusing only on the power generation efficiency, it is advantageous that the diameter of the wind turbine is somewhat large. However, the larger the wind turbine, the larger the wind power required.Therefore, if a design that emphasizes high efficiency and high output is adopted, the area where it can be installed is limited to strong wind areas. Occurs.

[0003] In addition, if the windmill is large, the problem of wind noise and safety becomes more important, and it must be installed in a so-called remote place where there are no houses around the living room. As far as performance and transmission losses are concerned, the advantage over other power generation systems such as thermal and hydropower must be reduced.

[0004]

As is well known, the use of water turbines and windmills as power sources has been practiced for a long time, including in agriculture. It is more important to be able to install close to the place of residence than to be energy efficient.

The present invention has been devised in view of such knowledge, and a main object of the present invention is to provide a wind power generator which can be handled relatively easily with less restrictions on an installation environment. It is in.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a wind power generating apparatus comprising a wind turbine connected to a shaft of a rotor of a generator, which is provided by rotating a wind turbine at a radially outer end. Trajectory
A shroud at least partially covering the opposing surface ;
A stay for interconnecting the shroud and the generator, and placing the shrouds with their axial end faces on a substantially common plane.
And a fastening means provided on the outer peripheral side of the shroud so as to interconnect a plurality of pieces in a state of being placed . In particular, a solar cell panel is provided on the inner peripheral surface of the shroud, a windmill, a housing for accommodating a generator,
And, the surface of the stay shall be subjected to mirror finishing, or the lead wire of the generator shall be provided so as to reach the fastening means via the inside of the stay, and the fastening means may be connected to establish electrical connection between the plurality of generators. It is good to be configured to do this.

[0007]

According to such a configuration, one unit can be reduced in size and weight, and a large number of units can be connected and assembled, so that the amount of budget and required output can be dealt with by increasing or decreasing the number of units. In addition, by using a solar cell together, it is possible to greatly increase the flexibility with respect to weather conditions in which power can be generated, and it is possible to increase the light-collecting efficiency by mirror-finishing each part. Further, if a lead wire of the generator is connected to the fastening portion, mechanical connection and electrical wiring of a plurality of units can be achieved at the same time, so that installation work is simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below in detail with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 shows a wind turbine generator 1 according to the present invention.
2 shows a configuration of a unit. This power generation unit 1
The capacity and capacity are set so that power can be generated even in a relatively weak wind.
A windmill 4 directly connected to the rotor shaft of the generator 3, and a windmill 4
And a cylindrical shroud 5 that covers the entire periphery of the cylindrical shroud.

The housing 2 is integrally formed with a pair of stays 6 extending outward in the radial direction. An outer end of the stay 6 and a connecting boss 7 provided on an outer peripheral surface of the shroud 5 are formed. By interconnecting, the shroud 5 and the generator 3 are mutually supported via the housing 2 and the stay 6. For this purpose, a nut 8 for screwing a bolt described later is inserted into the stay end. The surfaces of the housing 2, the windmill 4, and the stay 6 are mirror-finished, such as chrome plating, in order to maximize the light reflectance.

The stay 6 is formed in a hollow shape, and a lead wire 9 of the generator 3 extends inside the stay 6. The end of the lead wire 9 is connected to the connecting boss 7 of the shroud 5 at the stay 6, that is, the inserted nut 8
Is joined to.

A solar cell panel 10 is attached to the inner peripheral surface of the shroud 5 over the entire periphery. The surface of the solar cell panel 10 is covered with a light guide plate 11 made of a light guide synthetic resin material or the like.
As shown in FIG. 2, the front and rear edges protrude in the axial direction from the front and rear end edges of the shroud 5, and light can be taken in from this protruding surface. In order to maximize the use of the light energy taken into the solar cell panel 10 by the reflection and diffusion of light, fine reflector-like irregularities are formed on the surface thereof.

The connecting boss 7 on the outer peripheral surface of the shroud 5 is provided at a position where the circumference is equally divided into six so that the shrouds 5 having perfect circular contours can be closely connected to each other. When such connection is made, a maximum of three connection bosses 7 are fastened together by one bolt 12, but at this time, the axial end faces of the shrouds 5 are placed on a common surface. The three connection bosses 7 fastened by the common bolt 12 are shifted from each other in the axial direction, such as the front edge 7f, the center 7c, and the rear edge 7r.
In addition, for convenience in using the power generation units 1 in common, the axial positions of the connection bosses 7f, 7c, 7r are, for example, counterclockwise in the order of front (A) -middle (B) -rear ( C) -before (A) -medium (B) -after (C).

As shown in FIG. 3, a plurality of power generating units 3 are supported on a support pole 14 having a swivel shaft 13 rotatable about a vertical axis. It is fixed to. In this way, the direction of the windmill changes according to the wind direction by making it rotatable around the vertical axis, and if the base portion 15 is made rotatable about the horizontal axis, the direction of the shroud 5 can be changed by changing the direction in rainy weather. The inner surface (the solar cell panel 10) and the surface of the windmill 4 can be washed with rainwater. Note that fins and a horizontal axis rotation driving device for automatically aligning the surface of the windmill in the wind direction are provided on the base portion 15, but these are not shown.

It is desirable that the plurality of power generation units 1 be assembled symmetrically with respect to the support pole 14 as shown in FIG. 3, for example, as shown in FIG. It is preferable that the fixed configuration is a standard form.

Next, the electrical coupling will be described.

In order to simultaneously achieve the mechanical coupling and the electrical coupling of the power generating units 1 by bolting, the lead wire 9 built in the stay 6 is connected to the connecting boss 7r (C ), And the conductors 16 are inserted into the shroud 5 to connect the adjacent ones in series on the same row in series and electrically insulate them from those in the adjacent row. 7f (A) and the connection boss 7r (C) on the trailing edge side are internally connected, and the connection boss 7c at the center is connected.
(B) is in an insulated state (see FIG. 4). The power supply terminal of the solar cell panel 10 is connected to the conductor 16 that connects the connection bosses AC. As a result, the terminals obliquely adjacent to each other are connected in series, so that the terminals in each column may be connected in parallel (see FIG. 5).

As shown in FIG. 5, for example, if a four-stage pyramid configuration is used, one in which four power generation units 1 are connected in series and five in parallel are obtained. in this case,
It goes without saying that the connection between the left and right pairs and the connection between the columns are made using different conductors.

In the above embodiment, the shroud 5 has a cylindrical shape that covers the entire periphery of the wind turbine 4, but this is, for example, as shown in FIG. The shroud 51 may be shaped so as to cover a part around the circumference. According to this, when a plurality of units are connected, the shrouds 51 adjacent to each other complement each other and the entire periphery of each windmill 4 is covered. In this case, although the windmill of the unit located at the end is partially exposed, it goes without saying that this problem can be solved by separately setting a dedicated shroud to cover only that part.

[0020]

As described above, according to the present invention, one unit can be made small and lightweight, so that it is easy to transport and install, and a large number of units can be connected and assembled. And the required output can be dealt with by increasing or decreasing the number of units, so that the degree of freedom in setting the specifications is high, and even if some of the units fail, the functions are not completely stopped. In addition, since the mass production effect can be obtained by adopting the multiple unit system of small units, it is advantageous in terms of manufacturing cost.

Further, by providing a solar cell panel on the inner surface of the shroud, the panel area can be used to the utmost in spite of connecting and using a plurality of units, and not only direct light, indirect light, reflection, but also windmill In addition, by mirror-finishing the generator housing, the reflected light from these can be utilized with high efficiency. Moreover, solar cells and wind power
Since there is no mutual interference, the possible power generation time can be greatly increased.

Therefore, when used as a private power generation facility in a villa, a mountain hut, a campsite, or the like, or as an auxiliary power generation facility for home use, the overall energy saving effect is extremely large.
