Description

Twin-leaf wind power generators {TWIN BLADE WIND POWER GENERATOR}

The present invention relates to a wind power generator, and more specifically, up wind and down wind types are installed separately from the front and rear of the fuselage, respectively, to produce twice the power, and reduce the manufacturing cost and installation area. The present invention relates to a twin-leaf wind power generator, which is suitable for high-capacity power generation and is used in an environmentally friendly manner.

Common power generation methods include hydroelectric power generation, thermal power generation, nuclear power generation, etc. The above power generation methods require large-scale power generation facilities, and a large amount of oil or coal energy must be supplied to operate these power generation facilities. Therefore, at the present time when oil and coal resources are being depleted, a revolutionary power generation method that does not require oil and coal resources is required rather than general power generation methods such as hydropower, thermal power generation and nuclear power generation.

Such power generation methods that do not require petroleum and coal resources are also diverse, such as power generation using solar energy, wave power generation, tidal power generation, and wind power generation. Among them, wind power generation using wind power is the most applicable.

Wind power generation is a power generation that obtains power by converting a rotor into mechanical energy by using an aerodynamic characteristic of kinetic energy having air flow. In addition, wind power generation has no impact on the environment because it uses pollution-free and indefinite winds scattered everywhere, and the land can be used efficiently. It is a new level of energy generation technology.

As such, a propeller-type wind power generator that generates power by driving a generator by rotating the wind by installing a propeller applied to an airplane or the like for wind power generation has been widely used.

The propeller type wind power generator includes an up-wind type in which a propeller is installed in a wind blowing direction, and a downwind type in which a propeller is installed in a wind blowing direction.

However, the conventional propeller-type wind power generator has a disadvantage in that power generation is possible because it is irrelevant to rotation even if the direction of the wind is changed, but occupies a lot of installation area.

In addition, the conventional propeller-type wind power generator is not smooth to adjust the direction of the blades according to the wind speed and amount of wind, when the wind is strong, the problem of being damaged by applying excessive load to the main shaft or gear connected to the main shaft, generator, etc. There was.

The brackets fixed to the supports 84 and 184 fixed to the rotation blocks 83 and 183 of the first and second pivots 80 and 180 are integrally fixed to the rotation blocks 83 and 183. (86) (186) and the slide members (90,190) are integrally moved.

At this time, the rotation blocks 82 and 183 rotate with the outside of the ends of the first and second moving shafts 60 and 64 when the front and rear wings 6 and 8 rotate in opposite directions by the wind. The rotating blocks 82 and 183 may be moved back and forth in a state in which the first and second moving shafts 60 and 64 are not rotated by the bearings provided inside the blocks 82 and 183.

Subsequently, the slide members 90 and 190 rotate the operating shafts 92 and 192 which are slidably inserted into the slide holes 91, and the front and rear sides of the lever rotation centers of the operating shafts 92 and 192 are rotated. The operating shafts 92 and 192 are lever-rotated based on the rotation center of the vanes 6 and 8.

At this time, since the slide members 90 and 190 are connected to the rotation shafts 88 and 188 rotatably installed by the bearings of the brackets 86 and 186 according to the rotation of the operation shafts 92 and 192, the slide members 90 and 190 rotate. This is guaranteed.

In addition, since the rotating member 98 is rotated with respect to the housing 82 which is bearing-coupled through the bearing block 94 and the coupling member 96 by the rotation of the operating shaft 92, the rotation angle of the front blade 6 is Can be adjusted.

On the other hand, since the front wing 6 is inclined at an angle of about 3 ° with respect to the vertical plane, the bearing provided in the bearing block 94 helps to rotate while compensating the vertical angle of the operating shaft 92 to some extent. .

In addition, since the rotating member 98 is rotated with respect to the bearing-coupled housing 182 via the joint member 196 by the rotation of the operating shaft 192, the rotation angle of the rear wing 8 can be adjusted.

At this time, the second pivot 180 does not need to compensate for the vertical angle of the operating shaft 192 because the rear wing 8 is not inclined with respect to the vertical plane, so that the bearing block like the first pivot 80 is It may be directly coupled to the joint member 196 without having to be provided.

On the other hand, Fig. 14A shows an initial state (low wind direction), Fig. 14B shows an angle of elevation adjustment state (medium speed wind direction), and Fig. 14C shows a stationary state (high speed). Wind direction).

That is, Fig. 14A shows a cut in wind state, which is an initial state in which the wind speed is about 4 m / sec.

Referring to Figure 14 (b), it is preferable that the front and rear wings 6, 8 maintain a constant constant rotation regardless of the wind speed. To this end, this can be achieved by adjusting the rotation angle using the angle adjusting unit 50 of the front and rear wings 6 and 8 between the rated wind speeds of 12.5 m / sec to 25 m / sec.

14 (c) shows the case where the wind speed is 25 m / sec or more, and when the wind speed is 25 m / sec or more, if the wind power generator of the present invention is forcibly used, the front and rear wings 6 and 8 are broken. There is a problem that is broken. Therefore, the rotation angle of the front and rear blades 6 and 8 is maximized to prevent the wind from hitting the wing surface, thereby stopping the rotation of the front and rear blades 6 and 8.

Of course, the wind speed condition described above is a preferred embodiment, it can be applied to the twin-leaf wind power generator of the present invention by varying the wind speed conditions in various ways.

The number of teeth of the rotary ring gear 114 is configured to be slightly larger than the number of teeth of the fixed ring gear 130, so that the upper and lower gears 118 and 120 of the three planetary gears 116 are positioned at 120 degree intervals. In the portion, the gear value of the rotary ring gear 114 and the gear value of the fixed ring gear 130 is configured to match.

Therefore, even though the number of teeth of the rotary ring gear 114 and the number of teeth of the fixed ring gear 130 do not exactly match, the planetary gear 116 having the upper and lower teeth 118 and 120 having the same number of teeth is geared. It can be driven in a state of being engaged at equal intervals of 120 degrees without damaging the teeth.

The speed increaser 110 according to the present exemplary embodiment of the present invention converts the rotational speed to a high speed and provides the generator 42 to the generator 42 without making the planetary gear device in multiple stages, thereby reducing the number of components and improving the construction. It has an effect that can be made simple.
