Description

Wind Power Generator With High Efficiency And Enhanced Torque

The present invention relates to a torque increasing type high-efficiency wind power generator that generates electricity using wind.

Wind power generation is a technology that converts kinetic energy of air flow into mechanical energy using a rotor (fan, etc.), and converts it back into electrical energy.

Wind power generation is a power generation method that has little impact on the environment because it uses scattered, non-polluting, unlimited wind, and can use the land efficiently, and in the case of large-scale power generation complexes, the power generation cost does not fall compared to the existing power generation method. As a result, it has recently emerged as an alternative energy to fossil fuels, continuing its rapid growth.

A wind power generator usually includes a power generating fan that is rotated by wind power, and in addition to this, there are cases in which additional means for increasing power generation efficiency are added. For example, Korean Patent Laid-Open No. 2010-0036524 and Korean Patent Publication No. 2013-0026802 propose a wind power piezoelectric power generation device that generates power using wind power and a piezoelectric body, and Korean Patent Registration No. 10-0796441 and Korean Patent Laid-Open No. 2016-0092655 proposes a wind power generator using a pressure difference.

However, such a wind power generator has a limit in increasing power generation efficiency in an area where the wind is weak or the wind volume is small. Energy experts say that the power generation efficiency must exceed at least 30% to secure economic feasibility. The average wind speed in Korea is 7 m/s, which is relatively slow, the wind direction is not constant, and there are many regions with low wind volume. It is difficult to create.

In an area with low wind speed, a general propeller type wind power generator has a maximum angle of receiving wind of 45°, resulting in low power generation torque.

In addition, a phenomenon in which birds (birds) collide with the generator fan during rotation of the propeller-type wind power generator frequently occurs.

In order to solve this problem, there are cases where wind power generators are concentrated in a specific area where a certain amount of wind is generated. Even in this case, due to the enlargement of the power generation device, other problems such as securing an installation place and generating noise are caused. .

The present invention is to solve the problems of the prior art,

First, it can be installed and used as a small power generation device even in an area with low wind volume,

Second, it can be easily installed regardless of location.

Third, it is possible to actively develop while adapting to the change of wind direction,

Fourth, it is possible to control the amount of power generation by adjusting the wind pressure (air volume) applied to the rotor,

The wind power generator of the present invention for achieving this object may include first and second support plates, a rotary shaft, a wing support, a rotary blade, a rotary gear, a power generation gear, a power generation shaft, a support plate reinforcement, an air volume control cover, and the like.

The first support plate and the second support plate may be spaced apart to form a space therebetween. The first and second support plates may be configured in a plate shape.

The rotating shaft is axially rotatably coupled to the first and second support plates and may be configured in the form of a rod.

The wing support may extend radially to the axis of rotation.

The rotary blade may be coupled to the outer end of the blade support to rotate the blade support and the rotation shaft while moving according to the inflow of wind.

The rotating gear is configured as a cylindrical frame and can be coupled to a rotating shaft or a wing support. The rotating gear can rotate together according to the rotation of the rotating shaft or the wing support. The rotary gear may have first teeth on the inner surface or outer surface of the cylindrical frame.

The power generation gear may be provided with a second tooth coupled to the first tooth of the rotation gear on the outer surface. The power generation gear may be configured with a smaller diameter than the rotating gear and may have a higher rotational speed than the rotating gear.

One side of the power generation shaft may be coupled to the power generation gear to rotate according to the rotation of the power generation gear, and the other side may be coupled to the generator to transmit shaft rotational power to the generator.

The support plate reinforcing bar may be coupled to the first support plate and the second support plate to support the first and second support plates.

The air volume control cover may be coupled to the first and second support plates or the support plate reinforcement to adjust the amount of wind flowing into the space between the first and second support plates. The air volume control cover can pivot.

In the wind power generator of the present invention, the rotation gear and the power generation gear may each be provided with two symmetrically on the outside of the wing support along the axis of rotation.

The wind power generator of the present invention may include a cover support for supporting the air volume control cover. One end of the cover support may be axially rotatably coupled to the center of the first and second regulating plates, and the other end may be coupled to both upper ends of the air volume control cover.

In the wind power generator of the present invention, the first and second support plates may be formed of a 1/2 disk, and the air volume control cover may be formed of a disk of greater than 1/4 and less than or equal to 2/4. In this case, the air volume control cover may slide along the edges of the first and second support plates.

The wind power generator of the present invention may include a rotating vertical stand. The rotating vertical stand may rotate the first and second support plates so that the rotor blades face the direction in which the wind blows while rotating with respect to the horizontal direction.

In the wind power generator of the present invention, the rotor blades may face the wind at 90° to maximize torque.

In the wind power generator of the present invention, the rotary blade may rotate from the top to the bottom based on the area where the air volume control cover opens.

In the wind power generator of the present invention, at least one of the first and second support plates, the rotary blades, and the air volume control cover may form a light reflective coating film.

The wind power generator of the present invention having such a configuration can be installed in a small size, and furthermore, by adjusting the diameter ratio of the rotary gear and the power generation gear, the amount of power generation can be maximized, so that it is possible to generate sufficient electricity even in an area with a small amount of wind. can

The wind power generator of the present invention can actively respond to a change in the wind direction by automatically orienting the power generator in the direction in which the wind blows through the rotating vertical stand, and as a result, stable power generation is possible even in an area with severe wind direction change do.

The wind power generator of the present invention can adjust the wind pressure (air volume) hitting the rotor blades through the air volume control cover, and through this, it is possible to adjust the power generation amount as needed.

The wind power generator of the present invention can significantly increase the generated electricity than the conventional propeller-type wind power generator by increasing the torque of the generator. That is, in the present invention, since the angle of the wind received by the rotor blades is 90°, the torque generated by the rotor blades can be maximized.

The wind power generator of the present invention can prevent or minimize a phenomenon in which birds (birds) collide and die by implementing the rotation direction of the rotor blades in such a way that they always rotate from bottom to top. The reason why birds (birds) collide with the propeller-type wind power generator and die is that when the birds (birds) pass the rotating propeller, they cannot see the propeller coming down from the top and collide with the propeller. In other words, the range of vision of birds (birds) is between 180 and 270°, so they cannot see well at the back of the head and can hit the propeller.

In addition, the wind power generator of the present invention can fundamentally prevent birds (birds) from approaching by forming a light reflective film on the rotor blades and the like.
