Abstract

<P>PROBLEM TO BE SOLVED: To provide a windmill which generates electric power in the wind of velocity 3 m to 30 m/s with its wind power generator installed on a roof and is optimal as a small-sized and decentralized power generation, where there is no electric power transmission loss. <P>SOLUTION: In a wind collecting device, wind energy is received with a plate 1, and converted to a rotating axis 7 to generate power with a power generator 5. In the case of weak wind, rated wind velocity is set 5 m/s to 10 m/s. In the case of the wind 10 m/s to 30 m/s, the rated wind velocity is set 20 m/s to 25 m/s, and power is generated with the other power generator. The wind is stronger on the roof than that on a ground, and the construction cost is reduced by compensating a tower height with a building, and the manufacturing cost is reduced by the mass production to get 1 kw power at 1419. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wind turbine generator.

[0002]

2. Description of the Related Art Conventional wind power generators are all types installed on the ground, and this is the first Darrieus-type wind turbine that we have devised as a rooftop private power generator. The power generation by wind power depends on the speed of the wind, but the rotation of the wind turbine starts from around 5 m and is cut out at 25 m wind speed because it prevents danger and exceeds the predetermined number of rotations of the generator.

[0003]

In wind power generation, a rated speed at which the wind blows is set and power is generated when the rated wind blows. Even if it is more than that and less than that, wind power generation does not start 100%. By installing a wind collection panel, we will accelerate the wind of 3 m and install a low wind speed generator that generates electricity by the wind speed and a high wind speed generator when the wind speed becomes 20 m or more. Increase the effective utilization rate of wind turbines.

[0004]

[Means for solving the problem] Our idea is to install a Darrieus-type windmill on the roof of the building as a private power generator. The direction of the wind changes only 30-40 degrees throughout the year. From this, we will install a panel corresponding to an angle of 30 degrees in that wind. This makes it possible to control the wind and at the same time reduce the size of the wind turbine. It is a high-performance wind power generator that is completely different from conventional wind turbines.

BEST MODE FOR CARRYING OUT THE INVENTION Wind energy is received by a blade by a wind collecting device, converted into a rotating shaft and generated by a generator. If the wind is weak, set the rated wind speed to 5m-10m with a generator for low rotation. Also, the wind is 10m-3
When it is 0m, the rated wind speed is set to 20m to 25m and another generator is used to generate electricity.

The rotating shaft is a shaft of an automobile having a structure strong enough to withstand the use of thousands of rotations, and the bearing uses a hydraulic suspension for the upper part of the Darrieus wing and the pulley for transmitting the lower end power.

As for land and sea breeze, a strong wind blows from the sea in the daytime and a weak wind blows from the land to the sea at night, and the wind from the land does not blow only for use in wind power generation. The wind from the sea comes from an angle of 30 to 40 degrees throughout the year. As shown in Fig. 3, it corresponds to the wind angle and corresponds to all winds blown from the angle of 40 degrees where the panel is installed. As a result, the air receiving area is greatly expanded and a predetermined number of rotations can be obtained.
