Description

Wind power generator

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generator, and more particularly, to a wind power generator capable of generating stable power by generating a rotational power by a strong rotation moment action even when the wind speed is weak.

Generally, a wind power generator is a device that generates electric power by generating mechanical energy by wind force and then converting it into electric energy. Wind energy due to wind is infinite and clean, so it is recognized as an alternative energy.

As a new alternative energy generation device, the wind power generation device has a sufficient possibility. However, it is difficult to move the blade when the wind speed is low (for example, about 2 to 6 m / sec) There is a problem in that the efficiency of power generation is remarkably low.

To solve such a problem, Korean Patent Registration No. 10-1206701 discloses a wind turbine generator capable of generating wind at low wind speed. Such a wind turbine generator has an airfoil type wind capturer that generates an overlapping area based on the center shaft and generates lift force on a drag blade fixed and arranged in the same rotation direction so that wind drag and lift can be used at the same time, And accelerated the output coefficient so that wind power can be generated even in a small wind.

However, since the conventional wind power generation apparatus including the above-described prior art for generating power even at low wind speed is capable of increasing the rotational power of the blades by focusing the wind mainly by the shape and arrangement of the blades, When the wind speed is changed to 2 / sec or less, the rotation of the blades is rapidly lowered and the power generation efficiency is lowered. In addition, in the case of a strong wind such as a typhoon, the blades are excessively rotated to cause damage or breakdown of the blades, .

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a wind turbine generator in which a cylindrical rotor is rotatably mounted on a periphery of a horizontal rotary shaft and a blade is installed around the rotor, A plurality of weight eccentric operation chambers partitioned by the inner and outer ends of the weight eccentric operation chambers so as to allow weight water to flow into the inner and outer ends of the weight eccentric operation chambers in the downward rotational direction of the rotor, The present invention provides a wind turbine generator capable of generating stable power by generating a rotary power by a strong moment of rotation action of a rotor due to a weight deviation due to the center of gravity of a rotor in which weight water is collected at the inner end of the weight eccentric operation chamber .

Thereby generating a rotary power.

Wherein the weight eccentric action chamber is radially arranged with a water passage, and the first and second water collecting sections are respectively provided on the inside and the outside of the water passage so that a heavy water flow is made through the water passage, And the second outer collecting part is formed with a second extending space part which can be deflected toward the front of the rotor in the rotating direction.

The rotor is provided in a cylindrical shape, and the first and second collectors of the weight eccentric operation chamber provided in the rotor are provided in the same volume.

The first and second collectors are disposed in proximity to the inner and outer circumferential surfaces of the rotor, and the first collectors are alternately disposed at positions spaced apart from the inner circumferential surface and the inner circumferential surface of the rotor. Spaced apart from each other.

The present invention is characterized in that a wind power generating a rotational force by a wind which hits a blade is made, and a weight eccentric operation chamber which is partitioned in the inside of the rotor, It is a means by which the weight fluctuation is generated. Even when the wind speed is weak, it generates rotation power by strong rotation moment action. In the case of strong wind, it prevents the excessive rotation, It is effective.

The weight water 50 is made of water or oil and is not frozen even at a low temperature so that the weight water 50 can flow into the weight eccentric operation chamber 30 through a single injection port And the weight water 50 flows through the inner and outer ends of the weight eccentric operation chamber 30 to fill the weight of the weight eccentric action chamber 30. [

portions

31 and 32 on the inside and outside of the water passage 35, And the first accumulating portion 31 on the inner side is provided with a first extension space portion 50 for deflecting and accumulating the weight 50 toward the rear of the rotor 20 in the rotating direction, And the outer second reservoir portion 32 has a first extended space portion 31a for deflecting and collecting the weight 50 in the forward direction of the rotor 20 Respectively.

The first and second extended

space portions

31a and 32a of the first and

second collectors

31 and 32 are formed to be deflected rearward or forward with respect to the rotating direction of the rotor 20, The weight eccentric action due to the flow of the weight water within the weight eccentric operation chamber 30 can be performed according to the rotational position of the plurality of weight eccentric operation chambers 30 provided at the time of rotation of the weight 20.

second collectors

31 and 32 are rotatably supported by the rotor 20 and the circumference of the circumference of the rotor 20 are different from each other in consideration of the difference in circumferential circumference between the inner circumference and the outer circumference of the rotor 20. The first concentrator 31 is disposed at a position spaced apart from the inner circumferential surface and the inner circumferential surface of the rotor 20, And the first and

second collecting sections

31 and 32 are arranged so as to have substantially the same volume by arranging the second collecting section 32 equally spaced around the outer circumferential surface of the rotor 20 .

An embodiment of the wind turbine generator according to the present invention will now be described in detail.

The wind turbine generator of the present invention is a means for generating a rotational force by a wind which is provided around the horizontal rotary shaft portion 10 and hits the blade 40 provided at regular intervals on the outer circumferential surface of the rotor 20 rotated in the vertical direction Development is made.

At this time, the wind power generator according to the present invention not only generates rotational force by the blade 40 but also generates rotational power by a strong rotation moment action even when the wind speed is weak due to the center of gravity moving means provided inside the rotor 20 So that stable development can be achieved.

That is, when the power is generated in a state where the blade 40 is installed so that the rotor 20 rotates clockwise as illustrated in FIG. 5 of the present invention, the rotor 20 rotates in the downward rotational direction In the case of the weight eccentric operation chamber 30 which is placed at a rotating position in the second extended space 32a of the outer second accumulating part 32, Conversely, in the weight eccentric operation chamber 30 in which the rotor 20 is rotated in the upward rotational direction (9 o'clock direction), the weight water 50 is introduced into the first extended space portion 31a of the inner first accumulator portion 31, The rotational power can be greatly increased by the movement of the weight eccentricity in which the number of the teeth of the rotor is increased.

This is because in the case of the gravity eccentric operation chamber 30 located in the downward rotational direction (3 o'clock direction) of the rotor 20 with respect to the rotary shaft portion 10, The weight eccentricity for collecting the weight water is formed while the rotor 20 is rotated in the upward rotational direction (9 o'clock direction) of the weight eccentric action working chamber 30 to the inner first accumulating portion 31 The center of gravity moves in the downward rotational direction (3 o'clock direction) relative to the upward rotation direction (9 o'clock direction) of the rotor 20, A strong rotation moment continuously acts in the direction of the downward rotation (3 o'clock direction) to generate the rotational power.

As described above, in the wind power generator according to the present invention, the wind power generating the rotational force is generated by the wind that hits the blade 40, and the divided portion is partitioned inside the rotor 20 and the weight water 50 flows The weight eccentric operation chamber 30 having the eccentric action acts to generate a weight deviation in accordance with the rotational direction of the rotor 20 so that a strong rotational moment acts to increase the rotational force.

That is, in the weight eccentric acting chamber 30 located in the downward rotation direction (3 o'clock direction) of the rotor 20 with respect to the rotary shaft portion 10, weight water is supplied to the outer second water collecting portion 32 The gravity eccentric action of the rotor 20, which is continuously collected, allows the rotor to generate stable power by generating a rotary power with strong rotation moment action even when the wind speed is weak, On the other hand, when a strong wind such as a typhoon blows, it acts as a weight for preventing the weight 20 from being excessively rotated by the weight water 50 inserted into the weight eccentric operation chamber 30 inside the rotor 20 do.

Thus, according to the present invention, even when the wind speed is weak, a stable power generation can be achieved by means of generating a rotational power by a strong rotation moment action and preventing excessive rotation when strong wind is blown.

While the present invention has been described with reference to the exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
