1a is arranged in the opposite direction to the forward wind turbine 21 so as to rotate counterclockwise when viewed from above in response to wind at its pocket (see FIGS. 3 (a) and 3 (c)).

The forward wind turbine 21 and the reverse wind turbine 31 are respectively fixed coaxially to the rotating shaft of the generator 22 so that the forward wind turbine unit 20 generates clockwise rotation when viewed from above. A reverse power generation unit 30 that generates power by rotating counterclockwise when viewed from above is configured.

Each of the forward power generation unit 20 and the reverse power generation unit 30 has a lower portion of the generator 22 fixed to a rectangular fixed plate 23 in plan view. The fixing plate 23 partitions the inside of the casing 10 into a plurality of vertical chambers,
The normal rotation power generation unit 20 and the reverse rotation power generation unit 30 are fixed to the inner surface of the casing 10 via a bracket or the like so as to be alternately arranged.

That is, in the casing 10, the first power generation chamber 11, the second power generation chamber 12, and the third power generation chamber 1
Third and fourth power generation chambers 14 are formed, forward power generation units 20 are respectively supported in the first power generation chamber 11 and the third power generation chamber 13, and in the second power generation chamber 12 and the fourth power generation chamber 14, respectively. , Respectively, the reverse power generation unit 30 is supported.

Each wind inlet 10b is connected to each windmill 21,
The wind turbine 21 and the reverse wind turbine 31 which are adjacent to each other in the upper and lower directions are arranged so as to rotate in mutually opposite directions. That is, the air inlet 10b is
As shown in FIG.
, The right part of the second power generation chamber 12, the third power generation chamber 1

The wind guide plate 40 is a substantially flat member. When the casing 10 receives wind on the outer wall, the wind guide plate 40 efficiently guides the wind into the wind inlet 10b.
It is fixed to the outer wall surface of the camcorder by tilting it via a bracket or the like. Further, an illumination lamp for decoration or a signboard for advertisement is fixed to the wind guide plate 40 as necessary.

Next, the electric circuit of the wind turbine generator A is
This will be described in detail with reference to FIG. The generator 22 used in the wind turbine generator A is a DC type generator incorporating a diode for preventing reverse current, and outputs a voltage between terminals when rotated in a predetermined rotation direction. . Therefore, the generator 22 of the forward power generation unit 20 is configured to output a voltage between the terminals when rotated clockwise in a top view, and the generator 22 of the reverse power generation unit 30
It is configured to output a voltage between terminals when rotated counterclockwise in top view.

The wind power generator A having the above-described configuration is configured such that the respective generators 22 do not reverse due to the arrangement of the wind inlet 10b. Although no generator may be used, it is preferable from a safety standpoint to use the generator 22 having the above-described reverse current prevention circuit in anticipation of an unexpected situation such as when the casing 10 receives turbulent wind. .

In the plurality of generators 22, the positive (+) terminals are electrically connected to each other, and the negative (-) terminals are also electrically connected. That is, the plurality of generators 22 are electrically connected in parallel. The positive and negative terminals of the plurality of generators 22 are input to the battery 50, and
0 is electrically connected so that an output terminal of 0 is input to the inverter 60.

The configuration may be such that the power is reduced by reducing the number of generators 31 and the generator 22.

In the above embodiment, a DC generator is used as the generator 22. However, an AC generator can be used. However, in this case, since a phase difference may occur between the generators, it is preferable to use a DC generator as the generator 22 as in the present embodiment.

In the wind turbine generator A, the forward wind turbine 21 and the reverse wind turbine 31 are configured by using the bucket-like blades 21a in the opposite direction in order to improve the efficiency of receiving the wind. A windmill may be configured using flat blades. In this case, the rotation direction of the windmill is the wind inlet 1
