The present invention relates to a vertical wind turbine that is controlled speed and rotation according to the wind speed, and more specifically, when the wind is blowing windmill wings and windmill support in the direction of the wind blowing from the main axis and the horizontal support center axis or By forming the wind to be inclined in the opposite direction, the wind turbine is a vertical wind power generator that is controlled speed and rotation according to the wind speed can be obtained without damaging the windmill and obtain the maximum power output even in strong winds.

Wind power generation refers to a power generation method that runs a windmill by the wind of nature and uses a gear to speed up the generator. In this case, only 59.3% of the theoretical wind energy of the wing can be converted into electric energy, which can only be used as electric energy in consideration of efficiency, mechanical friction, and generator efficiency according to the shape of the wing. .

However, in recent years, the installation of wind power generators is rapidly increasing in Europe, and it is predicted that by 2020, it will reach 10% of the total generation of Europe. In addition, according to the data analyzed so far, the wind power system has established its technological power and lowers the cost of power generation, so that it can compete with fossil fuels even at the cost of power generation. It is expected to expand to.

Wind power generators are divided into horizontal type and vertical type according to the installation shape of windmill wings. In Korea, because there are few areas where the strong winds blow for a long time, it is efficient to use a vertical wind turbine suitable for rotating windmills using small wind pressure. Vertical wind turbines are easy to install on windmills, so they can be installed on roofs of houses or water tanks, making them easy to utilize, and suitable for installation on coastal houses and lighthouses with high winds.

However, if a sudden gust or a strong wind such as a typhoon blows, there is a high risk of damage to the windmills, especially windmill wings. Conventional vertical wind power generators responded to changes in wind speed and wind direction by adjusting the angle of the windmill blades, installing a windshield, or controlling the brakes. However, since the speed and direction of the natural wind are not constant, it is difficult to cope with conventional methods efficiently. Accordingly, there is a need for a vertical wind turbine that can flexibly cope with changes in wind direction and speed, and at the same time generate rotational power even with weak winds to generate and charge power.

The present invention has been made to solve the above problems, the object of the present invention is the direction of the wind blowing windmill wings and windmill support center and horizontal support center axis when the strong wind (horizontal support base It is formed to be inclined in the opposite direction where wind is blowing (when horizontal support is installed at the lower part of the supporting land) when wind turbines are installed at the top of the wind turbine, so that the windmill is not damaged and the maximum power output is obtained even in strong winds. To provide a vertical wind turbine that can be.

Another object of the present invention is to form a windmill support in a semi-cylindrical form to wrap half of the windmill blade to prevent wind is dispersed and to provide a vertical wind power generator with improved power generation efficiency.

In order to achieve the above object, the vertical wind turbine is a speed and rotation is adjusted according to the wind speed in accordance with a preferred embodiment of the present invention, the windmill is attached to the windmill shaft, and the rotation of the windmill by the power In the wind power generator having a generator unit for generating electricity, and a charging and power distribution device, the windmill support coupled to the windmill shaft to support the windmill, the wheel is provided to rotate with the windmill in accordance with the change in the wind direction, A horizontal support for supporting the windmill support, a horizontal support that combines the support and the windmill support, the horizontal support serving as a horizontal axis so that the windmill is inclined in a direction in which the wind blows or a reverse direction when the wind blows, and the A rail having a wheel configured to rotate without deviating from the position, and including a lower support fixed to the floor; Has a plurality of wind turbine blades around a vertical axis windmill formed is disposed vertically.

According to a preferred embodiment of the present invention, it is preferable that a rechargeable battery is used as the charging and distributing device.

According to another embodiment of the present invention, the windmill supporter may be formed in a semi-cylindrical shape surrounding half of the windmill blades to prevent wind from being dispersed and increase power generation efficiency.
Preferably, one side rear surface of the windmill support is attached to the wind direction support plate for rotating the windmill support and the support according to the change in the wind direction.

Hereinafter, with reference to the accompanying drawings will be described in more detail a vertical wind turbine is controlled speed and rotation according to the wind speed of the present invention.

1 is a perspective view showing a vertical wind power generator according to an embodiment of the present invention. According to Figure 1, the vertical wind power generator of the present invention a plurality of windmill blades 26 around the windmill shaft 24 is installed at regular intervals constitute a windmill, the windmill to securely support the windmill shaft 24 Support 22 is coupled.

On one side of the windmill support 22, the wind direction control plate 27 is installed so that the windmill 20 and the support zone 12 rotate together with the change of the wind direction. Wind direction control plate 27 is installed so as to protrude from the windmill 20, when the wind blows, the movement to rotate to be located in the opposite direction of the wind direction. At this time, since the support 12 and the windmill support 22 are connected by the horizontal support 28, the windmill 20 and the support 12 are due to the action of the wind direction control plate 27 according to the change in the wind direction. Will rotate together. Wheel 44 is formed at the bottom of the support 12, the wheel 44 is rotated along the rail 45 formed in the lower support 46, so the support 12 and the windmill 20 together It can rotate.

That is, when the wind direction control plate 27 rotates according to the wind direction, the support zone 12 and the windmill 20 rotate together, so that the entire windmill 20 rotates according to the change of the wind direction, and thus, the windmill 20 Rotational force and electric power generation efficiency are improved.

In order to increase the efficiency of the wind power generator, the windmill blades 26 should be easily rotated to obtain rotational power even in weak winds. Therefore, the windmill wings 26 may be formed in a rectangular planar shape, but in this case, since the difference in the force that the windmill wings 26 receive in the rotational direction and the anti-rotational direction is not large, the rotational force is obtained when the wind is weak. Is difficult. Therefore, in order to increase the efficiency of the windmill, it is preferable to make the windmill wings 26 bend in the same direction to receive more force in the rotational direction. That is, it is formed to rotate with the wind in the rotational direction to rotate with a lot of force, and in the anti-rotational direction so that the wind flows along the surface of the windmill blades 26 to receive less force than the rotational direction. As a result, a difference occurs in the wind pressure in the rotational direction and the semi-rotational direction, thereby obtaining rotational force even in a weak wind. Although not shown, the windmill shaft 24 and the windmill support 22 may be installed at a point where the windmill bearings intersect to firmly couple the windmill shaft 24 and the windmill support 22.

The lower support 46 is fixed with a bolt 48. The vertical wind turbine of the present invention may be installed outdoors, or may be installed on a house roof or a reservoir. Therefore, the lower support 46 may be fixed to the ground, it may be fixed to concrete or steel structures, etc., it is preferable to use an anchor bolt to securely fix.

Figure 2 is a longitudinal cross-sectional view showing a vertical wind turbine in front, according to an embodiment of the present invention. According to FIG. 2, the generator unit 30 is coupled to the lower part of the windmill shaft 24 to generate electricity by using power generated by the rotation of the windmill 20.

When the windmill wings 26 rotate under the influence of the wind, the windmill shaft 24 also rotates together. As the windmill shaft 24 rotates, the gears 32a and 32b installed in the generator unit 30 are driven to rotate the generator 34 to generate electricity. The generator unit 30 includes gears 32a and 32b for transmitting power generated by the rotation of the windmill shaft 24, a generator 34 for generating electricity, a current collector 38 for collecting generated electricity, and electricity. It is composed of a carbon brush 40 used to transfer to the charging and distributing device 50, the gear 32a is connected to a manual brake 36 to manually stop the rotation of the windmill 20. The gear may be classified into an external tooth gear 32a that rotates together with the windmill shaft 24, and an external tooth gear 32b that drives the generator 34 while rotating in engagement with the external tooth gear 32.

The electricity generated by the generator 34 is charged to the battery in the charging and distributing device 50 via the current collector 38 via the carbon brush 40, and the charged electricity is converted by the device to convert alternating current into direct current. It is supplied to electric users. As the battery of the charging and distributing device 50, a solar cell may be used, or a rechargeable battery that is generally used may be used.

The wheel 44 provided below the support 12 rotates along the rail 45, and is installed to surround the upper portion by the lower support 46, thereby preventing the support 12 from being inclined by the wind. It also plays a role.

In addition, a lower ball bearing 42 is provided at the lower portion of the support 12 to improve the rotational force while supporting the load of the support 12.

3 is a cross-sectional view illustrating the A-A cross section of FIG. 2. According to FIG. 3, the wheels 44 installed below the support 12 are installed to be in close contact with the rails 45 to prevent the tilt of the support 12, and according to the change of the wind direction, the support 12 is also a windmill. Rotate along rail 45 to rotate with 20. In addition, the thrust ball bearing 42 installed below the support post 12 serves to improve the rotational force while supporting the load of the support post 12.

4 is a side view illustrating a shape in which a windmill is inclined by a strong wind according to an embodiment of the present invention. According to FIG. 4, when the strong wind blows, the windmill 20 is tilted with the horizontal support 28 as an axis to prevent damage to the windmill 20. When the wind blows lightly, the windmill 20 is not affected by the degree of tilting. However, if a typhoon or a sudden gust of wind blows the windmill shaft 24 or windmill wings 26 may not be able to withstand the force of the wind may occur. At this time, by forming the windmill 20 to rotate around the horizontal support 28, the windmill 20 can be prevented from being damaged. At this time, when the horizontal support 28 is installed in the upper portion of the support 12 as shown in the lower portion of the windmill 20 is pushed by the wind is the windmill 20 is inclined.

Although not shown, when the horizontal support 28 is installed in the lower portion of the support 12, the upper part of the windmill 20 is adversely affected by the wind, so that the upper part of the windmill 20 is pushed backward and tilted.

When the wind of the same intensity, as the horizontal support 28 is installed closer to the center of the windmill support 22, the inclination of the windmill 20 becomes smaller, and installed farther from the center of the horizontal support 28 windmill support 22 The more the windmill 20 is tilted.

Vertical wind power generator of the present invention, by providing a plurality of vertical adjustment shaft support 29 in the support base 12, it is possible to adjust the height of the horizontal support 28 is installed. Therefore, by adjusting the height of the horizontal support 28 is installed in consideration of the usual wind speed and climate to prevent the windmill 20 from being damaged by the influence of strong winds and at the same time the rotational force of the windmill 20 even when strong winds blow You will get the advantages of securing electricity and generating electricity.

Conventional vertical wind turbines have no way of dealing effectively with strong winds such as typhoons or temporary gusts, causing major parts such as windmill wings, supports, or windmill shafts to be damaged. However, in the vertical wind power generator according to the present invention, when the wind is blown, the windmill 20 is inclined, so that the wind is smoothly and the windmill blade 26 rotates even in an inclined state, thereby generating electricity continuously. have.

5 is a perspective view showing a windmill according to another embodiment of the present invention. According to Figure 5, in order to improve the power generation efficiency by increasing the rotational force, the windmill support 22 is installed in a semi-cylindrical shape so as to surround half of the windmill wings 26 based on the wind direction control plate 27.

By blocking the wind blowing in the anti-rotation direction at the windmill support 22, the windmill acts only in the rotational direction to the windmill blades 26, thereby reducing the loss of rotational force can increase the power generation efficiency. And, because the through-hole is provided in the upper and lower portion of the windmill support 22, even if the windmill 20 is tilted, the wind is made smoothly. If the through-holes are not formed in the upper and lower portions of the windmill support 22, when the windmill 20 is inclined due to the strong wind, the windmill 20 or the support 12 or the horizontal support 28 is subjected to excessive force. The back may be damaged.
Referring again to the wind generator of the present invention.
When the strong wind blows the windmill support 22 is inclined in the direction of the strong wind blowing or the opposite direction and the angle of inclination changes according to the wind speed of the strong wind, the windmill is rotated at this time. That is, when the strong wind blows, the windmill support 22 is inclined with respect to the horizontal support base, so that the force by the strong wind is transmitted to the windmill as much as possible. When the wind blows, the windmill supports are inclined at a smaller angle, and when the wind is blown, it is inclined at a larger angle. This is to reduce the area of the windmill to meet the wind during strong winds so that the wind power transmitted to the windmill wings is less. That is, the windmill support is rotated during the strong wind, thereby protecting the windmill blade by reducing the horizontal cross-sectional area of the windmill blade hit the wind.
