As disclosed in each of Japanese Patent Publication No. 9-54769, Japanese Utility Model Publication No. 60-115122 and Japanese Utility Model Publication No. 2-96480, a wind turbine mounted on an automobile is rotated by using wind pressure received during traveling of the automobile to drive a generator. There is a wind turbine generator that is driven to charge a battery with electric power generated by the generator.

[0003]

All of the wind turbines used in this type of power generator are designed so that only the wind that blows relatively rearward is directly applied to the blades to rotate when the automobile is running. Inefficient use.

Further, the conventional wind turbine generator has not been devised to stabilize the rotation speed of the generator,
The output of the generator is not stable due to fluctuations in wind speed.

Further, in the conventional wind power generator, there is a risk that the wind turbine is not reliably started due to the rotational load of the generator, and in particular, when the vehicle is started, a wind speed sufficient to overcome the rotational load of the generator is obtained. Therefore, it is difficult to smoothly start the operation of the wind turbine.

[0006] Further, in the conventional automobile battery, one battery is used as a power source of an electric system, and the electric power generated from a generator driven by the rotation of an engine is constantly replenished and charged in the battery. Therefore, if the battery is exhausted with the engine stopped due to carelessness, the vehicle may not be able to move.

The present invention has been made in view of the above points, and its main purpose is to improve the efficiency of use of wind in a wind turbine generator, and further stabilize the rotation speed of a generator in the wind turbine generator. The other purpose is to make the wind turbine in the wind turbine generator start smoothly, and the other purpose is to ensure a battery that is always charged. .

[0008]

[0012]

According to the first aspect of the present invention, the wind is directly introduced into the forward wind passage on one side of the wind turbine, and at the same time, the wind reflected by the wind reflector is introduced into the reverse wind passage on the other side of the wind turbine. The wind turbines operate in a well-balanced manner by the wind pressures in opposite directions.

According to the second aspect of the present invention, even if the rotation speed of the wind turbine changes due to the change of the wind speed, the rotation speed of the generator is kept uniform by the one-way clutch and the flywheel. In particular, the generator continues to rotate due to inertial force even if the wind turbine is temporarily stopped.

According to the third aspect of the invention, since the mainspring spring can be lightly wound at the time of starting the windmill, the windmill can be started even in a slight wind, and the mainspring spring is wound until it exceeds a predetermined force (rotational load of the generator). Then, this mainspring spring serves as a rotation transmitting member and the generator starts rotating.

According to a fourth aspect of the present invention, when one battery is used as a power source, the other battery is charged by the generator, and when one battery is exhausted, the connection between the used battery and the charging battery is switched. , One of the batteries is connected to a generator for charging, and the other battery is used as a power source.
