Description

Wind generator that improves generation efficiency

The present invention relates to a wind power generator that achieves power generation using wind power, and is intended to achieve commercial development so that energy of wind power can be applied to reality and have maximum efficiency.

As is well known, there are many ways to get power without using fuel, such as hydropower, tidal power, solar cells, and wind power. Among them, wind power is a device that converts wind energy into electrical energy. Infinitely clean energy and short time required for infrastructure construction and small area required, there is a lot of research has been conducted.

However, although wind power has advantages between the above and the above, on the contrary, it remains a fundamental problem because the uniformity and sufficient amount of wind do not meet the required characteristics.

Conventional wind power generators are manufactured and constructed at an initial speed of 12m / s. The average wind speed in Korea's 2009 Chupyeong-ryeong region is 1 ~ 3m / s in 241 days and 3 ~ in 1 year (365 days). At 5 m / s, 100 days of the year and 5 to 6 m / s are 24 days of the year, which do not significantly reduce the rated wind speed, so that the desired power generation cannot be obtained compared to the performance of the wind turbine.

Therefore, wind turbines suitable for an average of 3 to 4 m / s are required. In particular, even if the wind is 3 to 4 m / s, wind power such as 5 to 6 m / s should be obtained.

On the other hand, in terms of the structure of the wind power generator, the general wind power generator is divided into a horizontal axis and a vertical axis, as if the rotary shaft is installed horizontally and the blade is formed at the end of the rotating shaft like a wing of a general fan is a horizontal shaft type, The vertical axis wind power generator is composed of several blades around the rotation axis with the rotation axis raised vertically.

The horizontal axis has a disadvantage of being affected by the direction of the wind a lot, the vertical axis is less affected by the direction of the wind, but the central axis of rotation is supported only the lower form of the structure is unsafe disadvantages to support the upper part of the rotation axis In order to ensure stability, there is a problem that the wind is interfered by the pillar for supporting the shaft, and the wind rotates only half the area of the vertically rotated rotor from the side, and the other half is the wind resistance. Since the wind turbine is vertical, the wind turbine must always use only about 1/2 of the wind blowing toward the rotor.

The present invention provides a power generation device having only the advantages of horizontal and vertical type by configuring so as to rotate stably like a horizontal power generation device while constituting a rotating body similar to a conventional vertical power generation device in wind power generation. While the wind wasted and blocked by the windshield is configured to act on the rotation of the rotating body at a higher rate according to the degree of the wind is intended to utilize the power of the wind more than 102%.

The present invention for achieving the above object is a horizontal axis of rotation is configured in the form of a rotating body on the outside, and constitutes a power generator in the form having a windshield to block the wind applied to the lower half of the rotating body.

In addition, the vane of the rotating body is configured to minimize the resistance of the wind when the semicircular windshield configured to have a semicircular cross section concave toward the wind by maintaining a constant interval when returning after 90 degrees after receiving the wind rotates And, the wind blowing side of the windshield is characterized in that it is provided with a guide means for inducing the wind blowing toward the windshield according to the degree of wind acting toward the rotating body.

According to the present invention, while solving the unstable installation of the rotating shaft which is a disadvantage of the existing vertical wind generators, it is possible to greatly improve the ratio of the wind acting on the rotor, which is another problem, especially the wind acting on the windshield side Most of them can act on the rotating body to improve the efficiency, and the guide plate that functions like this works to block the wind if it is too strong, thus preventing the remaining wind from disturbing the wing on the opposite side. Therefore, to provide a wind power generator that can obtain a stable power.

Hereinafter, a preferred embodiment for implementing the present invention will be described in detail with reference to the accompanying drawings.

In the wind power generator of the present invention, the windshield 10 concave downward is configured at the upper end of the support 1, and installs the rotor 20 having five wings 22 in the windshield 10, As the rotating shaft 21 of the rotating body 20 is horizontally installed, both ends of the rotating shaft 21 are supported on both sides of the windshield 10 to be smoothly rotated, and the rotating shaft 21 is the windshield 10. Due to being installed at the top of the three wings of the five wings 22 are installed to be located at the top of the windshield (10).

It is configured to have a radial blade 22 on the outer surface of the rotating shaft 21 is configured to rotate the rotating body 20 and the rotating shaft 21 by the wind, the generator 23 on both ends of the rotating body 20, respectively Is composed. The generator 23 is set to drive the two generators 23 at the same time when the wind is strong and only one generator 23 when the weak wind is used to generate the minimum wind.

In particular, in the wind power generator of the present invention, five blades 22 constituting the rotating body 20 are provided in a radial direction from a central rotation shaft 21, and each blade 22 has a semicircular windshield 22 '. ) Are continuous at regular intervals, and all the windshields 22 'of each wing 22 are semi-circular in a concave shape toward the wind.

In addition, the windshield 10 that covers the lower portion of the rotor 20 serves to prevent the wind from blowing to the lower half of the rotor 20 and hinders rotation. The up and down continuously constitute a plurality of inclined operating plate 30, the inclined operating plate 30 is installed by each of the center pin 31 is installed in a state capable of rotating up and down while the elastic sphere such as spring or rubber in the center ( 32) install the inclined operating plate 30 in a state where the wind is not blown or a slight wind is to allow the wind to pass between the inclined operating plate 30 while being inclined upward in the direction of the rotating body 20, If the wind is strong, while the inclined operating plate 30 is standing in a vertical or near vertical state while overcoming the elasticity of the elastic sphere 32 by the force of the wind is configured to block the wind or guide upward.

The upper portion of the rotor 20 is provided with a smooth curved guide plate 40 for inducing the wind passing thereon to act on the rotor.

It looks at the operation of the present invention having such a configuration.

When the wind blows in a state where the wind power generator of the present invention is installed, the wind is rotated by rotating the rotor 20 while pushing the wing 22 exposed to the top of the windshield 10, rotated by the rotor 20 It is possible to achieve the power generation by the generator 23 provided on both ends of the rotating shaft 21.

Since the vanes 22 according to the present invention have a semicircular windshield 22 'in a continuous form, the wind force is effectively collected to act on the rotation of the vanes 22, and between the semicircular windshields 22'. Since there is a space, when the wing 22 rotates to rotate the lower part (inside of the windshield), the wind passes through the space between the windshields 22 'to minimize the resistance of the air. This configuration minimizes the resistance during rotation while using the wind efficiently.

Part of the wind is blown in the direction of the windshield (10) as well as the rotating body 20 exposed above the windshield 10, this wind blows between the inclined operating plate 30 and slightly refracted upwards And immediately directed to the wing 22 is to help the rotation of the rotor 20.

This action varies depending on the wind, the wind blows strongly and overcomes the force of the elastic sphere 32, the inclined operating plate 30 is gradually rotated in the vertical direction, so if the wind is gradually stronger is supplied at an angle more upwards . This operation is such that when the wind is strong, the rotor 20 rotates to the extent that the wind blows to the upper part of the windshield 10 can produce sufficient power, and the rotor rotates while the strong wind blows and sufficient rotation is maintained. (20) If strong wind is supplied at an oblique angle at the lower end, resistance is generated rather than rotation, thereby impeding rotation.

In the strongest wind, the inclined operating plate 30 is completely vertical, while blocking the wind from being supplied between the inclined operating plate 30.

When the wind is weakened the inclined operating plate 30 is gradually opened again by the force of the elastic sphere 32 while the wind passed between them to help the rotation of the rotating body 20 to maintain the rotational force.
