Description

Wind power generator

The present invention relates to a wind power generator, and more particularly, to a wind power generator capable of producing electricity using wind power.

A wind power generation device refers to a device that generates electricity using the power of wind. Since wind power is a low-cost renewable energy source, wind power generation devices are used in various regions and countries today.

The wind power generation device can be classified into a vertical axis wind power generation device such as a Darius type or a Savonius type, and a horizontal axis wind power generation device of a propeller type, depending on the shape of the axis. Horizontal axis wind power generators are used evenly from small capacity to large capacity, and vertical axis wind power generation devices are widely used in wind power generation devices having a medium capacity or less. Here, the horizontal axis wind power generation device has better efficiency than the vertical axis wind power generation device, but is more affected by the wind, and may malfunction due to over rotation at an excessive wind speed. For this reason, in order to prevent the horizontal axis wind power generation device from being over-rotated when the wind speed is strong, various control methods exist.

As a control method for preventing the horizontal axis wind power generation device from being over-rotated, there are typically pitch control and stall control. Pitch control is a control method that controls the rotational speed of the blade by controlling the angle of the blade and controlling the amount of lift applied to the blade. Stall control is a control method that prevents the blade from rotating further when the wind speed reaches the limit wind speed. This is a method of controlling by the aerodynamic shape of the blade so that the lift does not act on the blade at the limit wind speed.

Among them, the existing pitch control measures the wind with an air flow meter, and the blade angle is controlled by electrical control based on the measured wind information value. However, when the angle of the blade is adjusted by electrical control, since a large electromagnetic wave is formed inside the generator, the electrical signal is not properly transmitted or output, and thus, the blade angle is not properly adjusted.

In order to solve the above problems, an object of the present invention is to provide a wind power generator that implements a blade angle adjustment in a mechanical manner in response to a change in wind speed.

The problem to be solved by the present invention is not limited to the above-described problems, and the problems not mentioned will be clearly understood by those skilled in the art from the present specification and the accompanying drawings. .

A linkage to be made; And an external force providing unit mediated by the interlocking unit so that the first rotating unit and the second rotating unit have different rotational movements even at wind speeds below a predetermined reference wind speed.

In addition, the external force providing unit does not provide external force to the interlocking unit such that the first rotating unit and the second rotating unit implement the same rotational operation by the interlocking unit at a wind speed equal to or less than a predetermined reference wind speed in the first state. In the case of the second state, an external force may be provided to the linkage so that the first rotation part and the second rotation part have different rotational motions at wind speeds below a predetermined reference wind speed.

In addition, the interlocking portion is connected to the second rotating portion, when the second rotating portion is rotated, an auxiliary shaft rotated in the same direction as the second rotating portion; And a rotation part which is mediated by the auxiliary shaft and is connected to the first rotation part and rotates in the same direction as the first rotation part when the first rotation part is rotated, wherein the external force providing part is in the second state. In one case, it may be characterized in that an external force is provided to the auxiliary shaft so that a different rotational motion is realized between the first rotating part and the second rotating part at a wind speed below the predetermined reference wind speed.

In addition, when the rotation unit, the first rotation unit and the second rotation unit different rotation operation is implemented at a wind speed equal to or less than the predetermined reference wind speed by the external force provided by the external force providing unit, the rotation is moved on the auxiliary shaft. It may be characterized by changing the angle of the first rotating portion.

In addition, the external force providing unit includes a driving unit that does not generate the external force in the first state, and a driving unit that generates the external force in the second state, and an external force transmission unit that transmits the external force generated in the driving unit to the interlocking unit. The external force transmission unit may be characterized in that when the driving unit is in the first state, the driving unit and the interlocking unit are not mediated, and when the driving unit is in the second state, the driving unit and the interlocking unit are mediated.

The wind power generator according to an embodiment of the present invention can prevent the blade from being damaged by strong wind speed.

In addition, the pitch angle of the blade can be adjusted by predicting in advance before the strong wind speed blows.

6 is a view for explaining a process of adjusting the angle of the blade of the wind turbine generator according to an embodiment of the present invention.

Below a predetermined reference wind speed, the first rotating unit 100 and the second rotating unit 200 try to perform different rotational operations, but the actual implementation may perform the same rotational operation.

As a specific example, referring to FIGS. 1, 2, 4, 5 and 6 (a), the first rotating unit 100 is intended to rotate clockwise by the first wind speed, and the second rotating unit 200 may attempt to rotate counterclockwise.

When the first rotation unit 100 is to be rotated clockwise, the rotation unit 620 may also be rotated clockwise accordingly.

That is, when the first rotating unit 100 is to be rotated in the clockwise direction, the rotating driving unit 120, the support 620a, the compression plate 620f, the elastic fixing unit 620b, and the elastic unit 630 ), The rotation limiting portion 620 such as the elastic limiting portion 620j and the first shaft fixing portion 620c may attempt to rotate clockwise.

In addition, when the second rotation unit 200 is to be rotated counterclockwise, the auxiliary shaft 610 connected to the second rotation unit 200 may also be rotated counterclockwise.

However, when the first wind speed is lower than the reference wind speed, if the force to be rotated in the counterclockwise direction is less than the elastic force of the elastic part 630, the second rotating part 200 is It can not be rotated in the clockwise direction, it can be rotated in the clockwise direction with the first rotating unit 100.

That is, the position moving part 620i is not moved by the elastic force by the elastic part 630, and the auxiliary shaft 610 may be rotated together with the rotation part 620. In other words, at the wind speed below a predetermined reference wind speed, the second rotating part 200 is the first rotating part due to the external force provided by the rotating part 620 to the auxiliary shaft 610 by the elastic part 630. It can be rotated in the same way as 100.

In addition, the external force added so that the auxiliary shaft 610 is rotated together with the rotating part 620 is added to the elastic force, that is, frictional forces between components, that is, frictional forces between the auxiliary shaft 610 and the position moving part 620i. It can be done.

At this time, since the position moving unit 620i is not moved, the angle of the first blade 110 may not be adjusted.

When the first wind speed increases and the first wind speed exceeds the reference wind speed, the first rotation unit 100 and the second rotation unit 200 may perform different rotation operations.

As a specific example, referring to FIGS. 1, 2, 4, 5 and 6 (b), as the first wind speed increases, the tendency of the second rotating part 200 to rotate in the counterclockwise direction is gradually increased. It can get bigger.

Then, when the first wind speed exceeds the reference wind speed, the second rotating part 200 exceeds the elastic force of the elastic part 630, the force to be rotated counterclockwise, and the second rotating part 200 A rotation operation different from the first rotation unit 100 may be implemented. In other words, at a wind speed exceeding the reference wind velocity, the second rotating portion 200 overcomes the external force provided by the revolving portion 620 to the auxiliary shaft 610 by the elastic portion 630, so that the second rotating portion 200 is It can be rotated differently from the one rotating part 100.

For example, the speed at which the second rotating part 200 is rotated clockwise may be slower than the speed at which the first rotating part 100 is rotated clockwise.

Alternatively, the second rotating part 200 may be rotated counterclockwise.

Alternatively, rotation of the second rotation unit 200 may be stopped.

When the second rotating part 200 rotates differently from the first rotating part 100, the threads of the position moving part 620i and the threads of the auxiliary shaft 610 act on each other, so that the position moving part 620i ) May be moved in the rear direction.

That is, the position moving unit 620i may be slid in the forward or rear direction on the auxiliary shaft 610.

In addition, as the position moving part 620i is moved, the elastic part 630 may gradually contract.

The compression tube 620d and the compression plate 620f may be moved by the movement of the position moving unit 620i.

The compression plate 620f may be moved while sliding on the support 620a.

In response to the positional movement of the compression plate 620f, the rod portion 620g is also moved, and in response to the positional movement of the rod portion 620g, the connection portion 620h can also be rotated.

The first blade 110 may be rotated in the longitudinal direction of the first blade 110 by rotation of the connecting portion 1620h.

10 is a view for explaining a process of adjusting the angle of the blade of the wind turbine generator according to another embodiment of the present invention.

When the first wind speed is equal to or less than a predetermined reference wind speed, the first rotation unit 100 and the second rotation unit 200 try to perform different rotation operations, but what is actually implemented may perform the same rotation operation.

As a specific example, referring to FIGS. 1, 2, 8, 9 and 10 (a), the first rotating unit 100 is intended to rotate clockwise by the first wind speed, and the second rotating unit 200 may attempt to rotate counterclockwise.

When the first rotation unit 100 is to be rotated in the clockwise direction, the rotation unit 1620 may also be rotated in the clockwise direction.

That is, when the first rotation unit 100 is to be rotated clockwise, the rotation driving unit 120, the support 1620a, the compression plate 1620h, the compression tube 1620f, the fixed tube 1620g, and The rotation unit 1620 such as the position moving unit 1620e may try to rotate clockwise.

In addition, when the second rotation unit 200 is to be rotated counterclockwise, the auxiliary shaft 1610 connected to the second rotation unit 200 may also be rotated counterclockwise.

However, when the first wind speed is lower than the reference wind speed, if the force to be rotated in the counterclockwise direction is less than the elastic force of the elastic part 1630, the second rotating part 200 is It can not be rotated clockwise, it can be rotated in the clockwise direction with the first rotating unit 100.

That is, the position moving portion 1620e is not moved by the elastic force by the elastic portion 1630, the auxiliary shaft 1610 may be rotated together with the rotating portion 1620.

In addition, the external force added so that the auxiliary shaft 1610 is rotated together with the rotation unit 1620 may be combined with frictional forces between components in addition to the elastic force.

At this time, the position moving unit 1620e is not moved, so the angle of the first blade 110 may not be adjusted.

When the first wind speed increases and the first wind speed exceeds the reference wind speed, the first rotation unit 100 and the second rotation unit 200 may perform different rotation operations.

As a specific example, referring to FIGS. 1, 2, 8, 9 and 10 (b), as the first wind speed increases, the second rotating part 200 tends to rotate in a counterclockwise direction. It can get bigger and bigger.

Then, when the first wind speed exceeds the reference wind speed, the second rotating part 200 exceeds the elastic force of the elastic part 1630, the force to be rotated counterclockwise, and the second rotating part 200 May perform a different rotation operation from the first rotation unit 100.

For example, the speed at which the second rotating part 200 is rotated clockwise may be slower than the speed at which the first rotating part 100 is rotated clockwise.

Alternatively, the second rotating part 200 may be rotated counterclockwise.

Alternatively, rotation of the second rotation unit 200 may be stopped.

When the second rotating part 200 performs a different rotation operation from the first rotating part 100, the threads of the position moving part 620i and the threads of the auxiliary shaft 1610 are acting on each other, so that the position moving part 1620e ) May be moved in the rear direction.

That is, the position moving unit 620i may be slid forward or backward on the auxiliary shaft 1610.

The compression tube 1620f and the compression plate 1620h may be moved by the movement of the position moving unit 1620e.

As the compression tube 1620f is moved in the rear direction, the fixed tube 1620g may be gradually inserted into the compression tube 1620f.

The compression plate 1620h may be moved while sliding on the support 1620a.

In response to the positional movement of the compression plate 1620h, the rod part 1620m is also moved, and in response to the positional movement of the rod part 1620m, the connection part 1620n can also be rotated.

The first blade 110 may be rotated in the longitudinal direction of the first blade 110 by rotation of the connecting portion 1620n.

Due to this, the first blade 110 is less affected by the first wind speed and can be prevented from being over-rotated by the first wind speed.

Here, the position moving unit 1620e may be moved in the rear direction until the force to move the second rotating unit 200 counterclockwise and the elastic force of the elastic unit 1630 is balanced.

Further, the position moving unit 1620e may be moved in the rear direction until the compression plate 1620h contacts the limiting part 1620i.

If, in the state where the position moving unit 1620e is moved, the first wind speed changes to a wind speed equal to or less than a predetermined reference wind speed, the position moving unit 1620e is moved in a forward direction, and accordingly, the first One blade 110 can also be rotated.

In other words, when the driving unit 710 is in the first state, power may not be applied to the driving unit 710, and when the driving unit 710 is in the second state, power may be applied to the driving unit 710. have.

In one example, the driving unit 710 may be a motor. In this case, when the driving unit 710 is in the first state, some of the components of the driving unit 710 may not be rotated because power is not applied to the driving unit 710, and the driving unit 710 is in the second state. In this case, power is applied to the driving unit 710 so that some components of the driving unit 710 are rotated to generate a rotational external force.

However, the present invention is not limited thereto, and the driving unit 710 may be variously modified at a level apparent to those skilled in the art.

The driving unit 710 may be disposed to face the external force transmission unit 720 based on the auxiliary shafts 610 and 1610.

In addition, the external force transmission unit 720 may not transmit the external force generated by the auxiliary shafts 610 and 1610 to the driving unit 710.

The external force transmission unit 720 does not mediate the driving unit 710 and the interlocking units 600, 1600 (secondary shaft) when the driving unit 710 is in the first state, and the driving unit 710 is not provided. In the case of the two states, the driving unit 710 and the linking units 600 and 1600 (secondary axes) may be mediated.

In one example, the external force transmission unit 720 may be connected to the one external force transmission unit 721 and the other external force transmission unit 722 when in a first state, and in the second state, the one external force transmission unit ( 721) and the other external force transmission unit 722 may be connected to each other.

To this end, power may be applied to the external force transmission unit 720, and may be moved from the first state to the second state or from the second state to the first state for position change.

The external force transmission unit 720 is the number of revolutions of the first transmission unit 741 fixed to the driving unit 710 and the number of revolutions of the fourth transmission unit 744 fixed to the auxiliary shafts 610, 1610. It can also perform the function of appropriately adjusting.

The first intermediary unit 731 may connect the first transmission unit 741 and the second transmission unit 742 to each other.

Accordingly, when the first transfer unit 741 is moved, the second transfer unit 742 may also be moved.

That is, the first intermediate unit 731 may transmit the external force generated as the first transmission unit 741 is moved to the second transmission unit 742, thereby causing the second transmission unit ( 742) can also be moved.

The second intermediary unit 732 may connect the third transmission unit 743 and the fourth transmission unit 744 to each other.

That is, the second mediator 732 may transmit the external force generated as the third transfer unit 743 is moved to the fourth transfer unit 744, thereby causing the fourth transfer unit ( 744) can also be moved.

In one example, the position movement may mean linear motion.

In one example, the first intermediate portion 731 and / or the second intermediate portion 732 may be a chain.

However, the present invention is not limited thereto, and the first intermediate portion 731 and the second intermediate portion 732 may be variously modified at a level apparent to those skilled in the art.

In one example, the first intermediate portion 731 and / or the second intermediate portion 732 may be a belt.

The first transmission unit 741 may be fixed to the driving unit 710.

12 is a view for explaining the operation of the wind turbine generator according to another embodiment of the present invention.

1 to 11, when the external force providing unit 700 is in the first state, the first rotating unit 100 and the agent are controlled by the interlocking units 600 and 1600 at wind speeds below a predetermined reference wind speed. 2, the external force providing unit 700 may not provide external force to the interlocking units 600 and 1600 so that the rotating unit 200 has the same rotational operation.

When the external force providing unit 700 is in the first state, it may mean a state in which power is not applied to the external force providing unit 700.

When the driving unit 710 is in the first state, the first rotation unit 100 and the second rotation unit 200 implement the same rotational movement by the linkage units 600 and 1600 at wind speeds below a predetermined reference wind speed. The driving unit 710 may not provide external force to the linking units 600 and 1600.

Referring to FIG. 12 as a specific example, the first rotation unit 100 may be rotated in the clockwise direction by the first wind speed, and the second rotation unit 200 may be rotated in the counterclockwise direction.

However, when the first wind speed is less than or equal to the reference wind speed, since the force to be rotated in the counterclockwise direction is less than the elastic force of the elastic parts 630 and 1630, the second rotating part 200 May be rotated in the clockwise direction with the first rotating part 100.

Detailed description of this may be omitted in the overlapping with the above-described content.

As the second rotation part 200 is rotated in the clockwise direction, the auxiliary shafts 610 and 1610 may also be rotated in the clockwise direction.

As the auxiliary shafts 610 and 1610 are rotated in the clockwise direction, the fourth transmission unit 744 may also be rotated in the clockwise direction.

As the fourth transmission part 744 is rotated in the clockwise direction, the second intermediate part 732 and the third transmission part 743 may also be rotated in the clockwise direction.

Here, the third transmission unit 743 is rotated, but the second transmission unit 742 may not be rotated.

At this time, power is not applied to the driving unit 710 as a first state, and the first transmission unit 741, the first intermediary unit 731, and the second transmission unit 742 may not be rotated. .

The external force generated as the auxiliary shafts 610 and 1610 are rotated may not be transmitted to the driving unit 710 through the external force transmission unit 720.

This may be because the external force transmission unit 720 does not mediate the driving unit 710 and the linkage units 600 and 1600.

At this time, the driving unit 710 is in a first state, and power may not be applied to the driving unit 710.

Due to this, when power is not introduced to the driving unit 710, damage to the driving unit 710, which may occur as the driving unit 710 is continuously rotated due to rotation of the auxiliary shafts 610 and 1610, is effectively prevented. Can be prevented.

In the above-described example, the clockwise direction and the counterclockwise direction are examples, and the rotational direction of the present invention is not limited thereto.

13 is a view for explaining the operation of the wind turbine generator according to another embodiment of the present invention.

Referring to FIGS. 1 to 11, at a wind speed higher than or equal to a predetermined reference wind speed, the external force providing unit 700 is in a first state, without providing external force to the interlocking units 600 and 1600, the first rotating unit 100. And the second rotation unit 200 may be implemented in a different rotation operation.

In other words, at a wind speed greater than or equal to a predetermined reference wind speed, the driving unit 710 is in a first state and does not provide an external force to the interlocking units 600 and 1600, the first rotating unit 100 and the second rotating unit ( 200) can be implemented the same rotation operation.

Referring to FIG. 13 as a specific example, as the first wind speed increases, the tendency for the second rotation unit 200 to rotate in the counterclockwise direction may increase.

Then, when the first wind speed exceeds the reference wind speed, the force that the second rotating part 200 is trying to rotate counterclockwise exceeds the elastic force of the elastic parts 630 and 1630 and the second rotating part 200 ) May be implemented with a rotation operation different from the first rotation unit 100.

When the second rotating part 200 implements a rotation operation different from that of the first rotating part 100, the position moving parts 620i and 1620e are moved in the rear direction on the auxiliary shafts 610 and 1610 to connect the connecting part. The (620h, 1620n) may be rotated, whereby the first blade 110 may be rotated based on the longitudinal direction of the first blade 110.

Detailed description of this may be omitted in the overlapping with the above-described content.

As the second rotation unit 200 is rotated in the counterclockwise direction, the auxiliary shafts 610 and 1610 may also be rotated in the counterclockwise direction.

As the auxiliary shafts 610 and 1610 are rotated counterclockwise, the fourth transmission unit 744 may also be rotated counterclockwise.

As the fourth transmission part 744 is rotated counterclockwise, the second intermediate part 732 and the third transmission part 743 may also be rotated counterclockwise.

Here, the third transmission unit 743 is rotated, but the second transmission unit 742 may not be rotated.

At this time, power is not applied to the driving unit 710 as a first state, and the first transmission unit 741, the first intermediary unit 731, and the first transmission unit 741 may not be rotated. .

Due to this, when power is not introduced to the driving unit 710, damage to the driving unit 710, which may occur as the driving unit 710 is continuously rotated due to rotation of the auxiliary shafts 610 and 1610, is effectively prevented. Can be prevented.

In the above-described example, the clockwise direction and the counterclockwise direction are examples, and the rotational direction of the present invention is not limited thereto.

14 is a view for explaining the operation of the wind turbine generator according to another embodiment of the present invention.

1 to 11, when the external force providing unit 700 is in the second state, the first rotary unit 100 and the second rotating unit 200 have different rotational motions at a wind speed equal to or less than a predetermined reference wind speed. To be implemented, the external force providing unit 700 may provide external force to the interlocking units 600 and 1600.

When the external force providing unit 700 is in the second state, it may mean a state in which power is applied to the external force providing unit 700.

When the driving part 710 is in the second state, the driving part 710 is the interlocking part so that the first rotating part 100 and the second rotating part 200 have different rotational motions at wind speeds below a predetermined reference wind speed. (600, 1600) can provide an external force.

The interlocking parts 600 and 1600 are connected to the second rotating part 200, and when the second rotating part 200 is rotated, the auxiliary rotating in the same direction and / or speed as the second rotating part 200 Simultaneously connected to the shafts 610 and 1610 and the auxiliary shafts 610 and 1610 and connected to the first rotating portion 100, and when the first rotating portion 100 is rotated, the same as the first rotating portion 100 It may be provided with a rotating portion (620, 1620) rotated in the direction and / or speed.

When the second state is the second state, the external force providing part 700 provides the external force providing part so that the first rotating part 100 and the second rotating part 200 have different rotational motions at a wind speed equal to or less than the predetermined reference wind speed. 700) may provide an external force to the auxiliary shaft (610, 1610).

The rotation unit (620, 1620) is the first rotation unit 100 and the second rotation unit 200 is different from the wind speed below the predetermined reference wind speed by the external force provided by the external force providing unit 700 When this is implemented, it may be moved on the auxiliary shaft (610, 1610) to change the angle of the first rotating portion (100).

Referring to FIG. 14 as a specific example, the first rotation unit 100 may be rotated in the clockwise direction by the first wind speed, and the second rotation unit 200 may be rotated in the counterclockwise direction.

However, when the first wind speed is less than or equal to the reference wind speed, since the force to be rotated in the counterclockwise direction is less than the elastic force of the elastic parts 630 and 1630, the second rotating part 200 May be rotated in the clockwise direction with the first rotating part 100.

Detailed description of this may be omitted in the overlapping with the above-described content.

Power is applied to the driving unit 710 so that some components of the driving unit 710 may be rotated, and accordingly, the first transmission unit 741, the first intermediary unit 731, and the second transmission unit ( 742) can also be rotated.

For example, the first transmission unit 741, the first intermediary unit 731, and the second transmission unit 742 may be rotated counterclockwise.

As the second transmission unit 742 is rotated, the third transmission unit 743 may be rotated, and as the third transmission unit 743 is rotated, the second intermediate unit 732 and the The fourth transmission unit 744 may also be rotated.

For example, the third transmission unit 743, the second intermediate unit 732, and the fourth transmission unit 744 may also be rotated counterclockwise.

The external force transmitted to the fourth transmission part 744 and the auxiliary shafts 610 and 1610 by the second intermediate part 732 and the auxiliary shafts 610 and 1610 are counterclockwise by the second blade. When the force to be rotated is stronger than the elastic force of the elastic parts 630 and 1630, the auxiliary shafts 610 and 1610 and the second rotating part 200 may be rotated counterclockwise.

When the second rotating part 200 implements a rotation operation different from that of the first rotating part 100, the position moving parts 620i and 1620e are moved in the rear direction on the auxiliary shafts 610 and 1610 to connect the connecting part. The (620h, 1620n) may be rotated, whereby the first blade 110 may be rotated based on the longitudinal direction of the first blade 110.

Detailed description of this may be omitted in the overlapping with the above-described content.

The external force generated as some components of the driving unit 710 are rotated may be transmitted to the auxiliary shafts 610 and 1610.

This may be because the external force transmission unit 720 mediates the driving unit 710 and the linkage units 600 and 1600.

In this case, power may be applied to the driving unit 720 as the second state.

Due to this, the first wind speed is below the reference wind speed, but in preparation for the first wind speed to be stronger, the angle of the first blade 110 may be adjusted by applying power to the driving unit 710.

When the external force providing unit 700 is in the second state, the external force providing unit 700 may further rotate the first rotation unit 100 and the second rotation unit 200 at different wind speeds than a predetermined reference wind speed. An external force may be provided to the linking units 600 and 1600.

In other words, when the driving unit 710 is in the second state, the external force providing unit (so that the rotational movements of the first rotating unit 100 and the second rotating unit 200 are more different at wind speeds higher than a predetermined reference wind speed) 700) may provide an external force to the linkage (600, 1600).

The difference in rotational motion means that the rotational speed between the first rotating part 100 and the second rotating part 200 is different when the external force providing part 700 is in the first state at a wind speed higher than a predetermined reference wind speed. It may mean that the difference between the rotational speeds of the first rotation unit 100 and the second rotation unit 200 is greater.

A detailed example of applying an external force to the auxiliary shafts 610 and 1610 by applying electric power to the driving unit 710 may be omitted in detail overlapping with the above.

Due to this, when the second rotating part 200 is not properly rotated at a predetermined wind speed or higher due to an error of the second blade 210, etc., the angle of the first blade 110 is not properly adjusted. In addition, by using the external force providing unit 700, the angle of the first blade 110 may be appropriately adjusted to the first wind speed.
