DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a vertical axis wind turbine generator.

[0002]

2. Description of the Related Art Conventionally, there have been many cases where construction machines and equipment are inconvenient due to lack of a suitable power supply device. For example, cable cranes are being automated and remote-controlled, but their trolleys include industrial TV cameras for monitoring suspended loads, radios for transmitting image data, G
Devices that require a power source such as a PS receiver, a radio device for transmitting the same data, a concrete bucket posture monitoring device, and a concrete placement target position setting device are mounted, and an appropriate power supply device is required for these devices.

[0003] In addition, a traveling triangular block for a track-type cable crane, a GPS receiving antenna and a radio transmitter installed in a mountainous area or a seaside, a total station for automatic surveying, Communication power supply-There are many cases that require a small power supply such as landslide monitoring equipment in mountainous areas.

[0004] In such cases, most are engine-powered generators, batteries, or solar power (solar).
Power generation, etc. is installed to deal with this problem, but with engine-type generators, problems such as refueling, maintenance, noise, etc., for batteries, supplementary charging and replacement are required, and for solar power generation,
It is not practical because it needs a considerable size to secure the required capacity,
In addition, there are problems in that they cannot be used continuously depending on the weather and time.

On the other hand, the use of a wind power generator is conceivable.
A conventional and generally commercially available wind power generator is a generator 30 using a propeller 32 as shown in FIG.
The vertical tail 33 turns according to the wind direction.

When such a wind power generator 30 is used for a construction machine or the above-mentioned application, a large installation space is required. That is, the height to the tip of the propeller and the turning diameter from the mounting stand or pole to the vertical tail are required. -Enclosure such as protective wire mesh is necessary to ensure safety during inspection and refueling work of machines. -Safety measures in strong winds are complicated. -Energy conversion efficiency is not good because the vertical tail rotates and follows the change in the wind direction in the horizontal direction. There is a problem.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention addresses the above problems and does not require a large installation space.
It is another object of the present invention to provide a wind power generator that can easily secure safety during maintenance and take measures against strong winds and has high energy conversion efficiency.

[0008]

According to the present invention, a wind turbine rotor for driving a generator is rotatably provided around an upright rotating shaft, and a plurality of shielding plates are provided around the rotating periphery of the wind turbine rotor. The wind turbine rotor is rotatably provided by a support shaft parallel to the rotation axis of the wind turbine rotor, and the shielding plates are rotated and opened and closed in conjunction with each other to block the flow of wind into the wind turbine rotor.

In addition, a wind speed detecting means is provided, and a control device for controlling the closing of the shielding plate in a strong wind by a signal from the wind speed detecting means is provided.

Therefore, according to the present invention, the wind speed is detected by the wind speed detecting means, and when the wind speed is higher than a predetermined wind speed, a plurality of shield plates provided around the wind turbine rotor are closed to block the flow of the strong wind into the wind turbine rotor. And operate the vertical axis wind power generator in the same manner.

Further, since the wind turbine is a vertical axis wind turbine, it can be operated regardless of the direction of the wind, and the whole apparatus is compactly configured, and can be easily installed and moved in a narrow space.
In addition, maintenance is easy and safety during work can be ensured.
Therefore, in the past, it was difficult to install a generator
It can also be installed in places, and can be applied to environmentally friendly and energy-saving wind power generation.

In the practice of the present invention, it is preferable to mount the vertical wind power generator on a traverse trolley of a cable crane, for example, in a dam construction work. In the case of such a configuration, it is preferable that a traveling tower and a fixed tower are provided, a concrete bucket is hung on a trolley that traverses a cable stretched therebetween, and a wind power generator is mounted.

With this configuration, a wind speed corresponding to the traversing speed can be obtained while the trolley is traversing, and even when the trolley is stopped, power can be continuously generated by the natural wind regardless of the wind direction. In addition, since the traverse trolley is riding on a cable, if the wind power generator according to the present invention is mounted at one place, the balance may be poor and may be unstable. However, in such a case, the arrangement may be devised or two or more wind power generators of the present invention may be installed to balance the trolley.

Further, according to the present invention, it is most suitable for unmanned equipment for fixed point observation, for example.
