Description

Movable rotary wing structure for vertical wind power generation

The present invention relates to a mobile rotary wing structure for vertical wind power generation, and more particularly, the wing is configured to be movable in the direction of the forward rotation from the direction of the reverse rotation with respect to the wind direction about the vertical axis of rotation to the forward rotational force against the wind The present invention relates to a mobile rotary wing structure for vertical wind power generation that can maximize power production efficiency by wind power.

Wind power generation refers to a power generation method in which wind energy is converted into mechanical energy (rotational power) through a rotating shaft using a windmill, and the mechanical energy is converted into electrical energy by driving a generator to obtain power. It is not only the most economical among the new renewable energy sources, but also has the advantage of being able to generate power using the wind, a clean energy source for unlimited use, and actively invested not only in Europe where the wind power industry was developed but also in the Americas and Asia recently. It is happening.

Particularly, wind power generation has cost-effective aspects such as improving the price competitiveness of electricity production costs and minimizing the required area of power generation systems, and the social and environmental aspects such as protecting the global environment such as alternative energy sources and fogging of fossil energy exhaustion. In addition, the government is actively supporting the dissemination of wind power generation due to economic advantages such as stability of supply and reduction of dependence on energy imports. Accordingly, it is expected that the growth of wind power generation in Korea will increase in the future.

Such wind power generation can be classified into a horizontal wind power generator in which the rotating shaft is installed horizontally with respect to the ground and a vertical wind power generator in which the rotating shaft is installed perpendicular to the ground according to the direction of the rotation axis of the blade. Compared to the vertical type, the horizontal wind power generator is more efficient and stable, so most of the commercial wind farms have been applied to the horizontal wind generator.

The above-described horizontal wind power generator has the advantage of realizing high power generation efficiency in the most general form, but it is difficult to smoothly generate power in areas where the wind direction is frequently changed, and expensive installation is possible because the main parts including the rotor are installed at a high level. Not only is it expensive, its maintenance is not easy, and it has a disadvantage that is structurally vulnerable to strong winds such as typhoons.

Compared with the shortcomings of the horizontal wind power generator, the vertical wind power generator can generate power regardless of the direction of the wind. Since the main components such as the gearbox and the generator are installed on the ground, the installation cost is low and the maintenance is performed. Has the advantage of being easy.

Nevertheless, the horizontal power generator is preferred as described above because the vertical power generator is less efficient than the horizontal power generator.

This is a structural problem of the vertical wind power generator, because the blades rotate in a plane parallel to the wind direction, unlike a horizontal power generator in which the blade rotates on a plane perpendicular to the wind direction.

That is, as shown in Figure 18, the vertical wind power generator structurally converts the energy of the wind (W) to the mechanical rotational force of the rotating shaft (b) while one side (a1) of the rotary blade is rotated forward by the wind However, since the opposite side (a2) of the rotary blade to the reverse rotation with respect to the wind will act as a resistance to the rotation of the rotary shaft (b) will have to decrease the conversion efficiency of mechanical energy.

Recognizing the problems of power generation efficiency of the vertical wind turbine, various technologies have been developed to reduce the resistance. It was to receive less.

However, since the shape deformation technology of the existing rotary blade has a limitation in reducing the resistance, it is difficult to greatly increase the power generation efficiency. Therefore, it is urgently required to develop a technology capable of removing the reverse resistance to the wind direction.

As shown in the drawings, the movable rotary wing structure 1 according to an embodiment of the present invention is a wing frame 10, and a movable wing installed to be slidably movable on the wing frame 10 ( 20) and the wing operation control unit for controlling the sliding operation of the movable blade (20).

The wing frame 10 is formed in a rectangular shape as a whole, the upper and lower ends are formed so that the rails 11 are opposed to each other in the horizontal direction.

In addition, a plurality of bending preventing reinforcement pieces 12 are coupled to the rail parts 11 along a longitudinal direction, and a plurality of reinforcing supports 12 are coupled between the rail parts 11.

The wing frame 10 is installed to be fixed to the vertical axis of rotation (3), divided into two parts are fixed in parallel to both sides of the vertical axis of rotation (3). Here, the wing frame 10 can be seen that if one wing frame rotates forward with respect to the wind direction, the other wing frame rotates in the reverse direction.

And the wing frame 10 is made of a pair is preferably installed to be orthogonal to each other in the form of a cross on the vertical axis of rotation (3).

Here, a wing through hole 4 having a length corresponding to the separation interval of the rail portion 11 is formed on the vertical rotation shaft 3 on which the wing frame 10 is installed, and the wing through hole 4 crosses. It is preferable to be formed on the outer circumferential surface of the vertical rotation shaft 3 at 90 ° intervals corresponding to the wing frame 10 installed in the form. The wing passage 4 is to function as a passage to pass through the vertical axis of rotation (3) during the movement of the moving blade 20 to be described later.

In addition, a cross-shaped wing passage 5 is formed in the vertical rotation shaft 3 so as to correspond to the wing passage 4 so that the moving blade 20 easily passes through the vertical rotation shaft 3. desirable.

The moving wing 20 is installed on the wing frame 10 to be slidable along the rail portion 11 of the wing frame 10.

The wing 20 is in the form of a square plate like the wing frame 10, it is preferable to have a length of about half of the entire length of the wing frame (10). That is, the length of the moving blade 20 corresponds to the length of any one of the wing frame 10 divided into two parts, accordingly from the two wing frame 10 fixed in parallel to both sides of the vertical axis of rotation (3) By movement, it can be selectively positioned on either side.

Since the wing frame 10 is made of a pair of orthogonal to each other it can be seen that the moving wing 20 is also made in a pair to be installed on each wing frame 10.

The movable blade 20 is installed to be slidably moved along the rail portion 11, in one embodiment of the present invention, as illustrated in FIG. 3 for sliding movement of the movable blade 20. (11) coupled to the rotary blade 21 to the rotary blade 21 that can be rotated while minimizing the friction, the method for sliding movement of the movable blade 20 is limited to the above embodiment However, various sliding schemes known in the art are possible.

The wing operation control unit performs a function of controlling the sliding movement of the movable blade 10 so that the movable blade 10 is located only on the wing frame 10 side that always rotates forward with respect to the wind direction even if the wing frame 10 is rotated. do.

As an embodiment for this purpose, the wing operation control unit may be made of a wind direction indicator 30, the approach detection sensor 40, the wing drive unit 50, the wing detection sensor 55.

The wind direction indicator 30 is coupled to the vertical rotation shaft 3 by the bearing rotation part 31 so that the direction can be changed freely according to the wind direction irrespective of the rotation of the vertical rotation shaft 3, and thus the wind direction indicator 30 is always located in parallel with the wind direction.

Here, one wing frame 10 passes through the wind direction indicator 30 every 180 ° while rotating by the wind, so the wind direction indicator 30 is in a position parallel to the wind direction 30 wind direction indicator 30 It can be seen that each time the blade frame 10 is passed from the forward rotation to the reverse rotation with respect to the wind direction.

The approach sensor 40 is provided in the wind direction indicator 30 to approach the wind direction indicator 30 while rotating as described above to detect the wing frame 10 to be switched from the forward direction to the reverse direction to be described later It functions to operate the driving unit 50.

Here, since the moving time of the moving wing 20 should be taken into consideration, the approach detection sensor 40 needs to detect the wing frame 10 before it is switched from the forward direction to the reverse direction with respect to the wind direction to operate the wing drive unit 50. For this purpose, the proximity sensor 40 is preferably provided in the wind direction indicator 10 so as to be spaced apart 5 ~ 10 ° in the opposite direction of rotation of the wing frame 10 from the wind direction indicator 30. .

The wing sensor (55) consists of a pair is installed on both ends of the wing frame (10), respectively. Each wing detection sensor 55 is a function of detecting whether the movement of the moving wing 20 moving along the wing frame 10 is completed, respectively, moving wing 20 toward the wing frame 10 installed. Sliding movement by the operation of the wing drive unit 50 reaches the end of the wing frame 10 to detect this to stop the operation of the wing drive unit (50).

The wing drive unit 50 is operated according to the detection signal of the approach detection sensor 40 when the wing frame 10 is approached to the point that is switched in the reverse direction moving wing 20 located on the approach wing frame 10 side To function to move to the opposite wing frame 10 side.

To this end, the wing drive unit 50 is a rack gear 51 is installed on one side of the movable blade 20 along its length direction, and a pair of pinion gears that can be engaged with the rack gear 51, respectively ( 52 and a pair of forward and reverse motors 53 installed on each of the wing frames 10 on both sides of the vertical rotation shaft 3 to rotate the pinion gear 52 in the forward and reverse directions, respectively.

The stationary motor 53 is driven to rotate according to the detection signal of the approach detection sensor 40 to move the moving wing 10, and stops the rotation drive in accordance with the detection signal of the wing detection sensor (55).

On the other hand, since the moving blade 20 is to reciprocate every 180 degrees of the rotation angle along the wing frame 10, for this purpose, the pair of forward and reverse motor 53 is the rotation angle of the wing frame 10 180 You must repeat the forward and reverse drive alternately every °.

Various control schemes may be adopted for the forward and reverse driving of the forward and reverse motors 53. As an embodiment, the approach detection sensor 40 may access one wing frame and the other wing frame of the wing frame 10. A pair of transmitters for differently detecting and transmitting different signals to one wing frame and the other wing frame of the wing frame 10 so as to drive the forward and reverse motor 53 forward or reversely accordingly. Not shown) can be installed.

Referring to the operation of the movable rotary wing structure 1 according to an embodiment of the present invention made of the above-described configuration is as follows.

5 to 9 are cross-sectional views of the operation of the wing frame 10 of the movable rotary wing structure according to an embodiment of the present invention according to the progress of rotation.

As shown in FIG. 5, the wing 20 is positioned on one wing frame 10a that rotates forward with respect to the wind, and the wing 20 is positioned on the other wing frame 10b that rotates against the wind. )

Therefore, in this case, the forward rotational force of the wind acts greatly on one side of the wing frame 10a on which the moving wing 20 is located, whereas the minute reverse rotational force (the wind force only affects the wing frame itself) is applied to the other wing frame 10b on the opposite side. ) Only a large forward rotational force is applied to the vertical axis (3) as a whole.

And as shown in Figure 6, when the wing frame 10 is further rotated closer to the wind direction indicator 30 is located near the direction of the wind vane frame 10a is subjected to the forward rotation force, the wind direction approach sensor At 40, the approach of the wing frame 10a is detected. At this time, since the approach detection sensor 40 is spaced 5 to 10 ° in front of the wing frame 10a is detected before reaching the position parallel to the wind direction indicator (30).

The stationary motor 53 of the wing drive unit 50 is operated according to the detection signal of the approach detection sensor 40, and the rotational movement of the pinion 52 is the rack gear 51 according to the operation of the stationary motor 53. Is converted to a linear motion of the wing 20 is to start the sliding movement toward the other wing frame (10b) on the opposite side from the approach one wing frame (10a).

7 to 9, when the one-side wing frame 10a, which was previously rotated in the forward direction, is converted to reverse rotation through the wind direction indicator 30, the moving blade 20 is conventionally rotated in the reverse direction. It is located on the other wing frame (10b) side is converted to the forward rotation, so that only the forward rotational force by the wind is continuously applied to the wing frame (10).

Such movement of the wing 20 is to be made for each 180 ° rotation of each wing frame 10, through this operation is to remove the reverse resistance to the vertical axis of rotation (3) and only the forward rotational force is applied.

10 is a perspective view showing a movable rotary wing structure 2 according to another embodiment of the present invention, as shown in the above drawings, the movable rotary wing structure 2 according to another embodiment of the present invention is The pair of wing frames 10 fixed to the vertical rotation shaft 3 in the form of a cross, and the configuration of the movable wing 20 to be slidably movable on the wing frame 10 is the same as the above-described embodiment However, the configuration of the wing operation control unit for moving the moving wing 20 toward the wing frame 10 for forward rotation when switching from the forward direction to the reverse direction with respect to the wind direction has a different feature.

Therefore, hereinafter, components different from those of the above-described embodiment will be described in detail, and the same reference numerals will be used for the same elements as those of the above-described embodiment, and a detailed description thereof will be omitted.

The wing operation control unit according to another embodiment of the present invention includes a wind direction indicating member 60, a wing movement guider 70, and an elastic body 80.

The wind direction indicating member 60 is vertically rotated by a bearing rotating portion 61 so that the direction can be freely changed according to the wind direction regardless of the rotation of the vertical rotation shaft 3, similar to the wind direction indicator 30 of the embodiment. Coupled to (3).

As long as the wind direction indicating member 60 extends longer than the rotation radius of the wing frame 10 in a pair of bearing rotating portions 61 respectively coupled to the upper and lower vertical rotation shafts 3 of the moving blades 20. Preferably, the pair of horizontal bars 62 and the inclined plate member 63 are bent at a predetermined angle at the ends of the pair of horizontal bars 62.

The wind direction indicator 30 of the above-described embodiment is located in parallel with the wind direction, but the wind direction indicator member 60 is the pair due to the inclined member 63 bent in the rotational direction of the wing frame 10 As shown in the figure, the horizontal bar 62 is positioned at a predetermined angle in a direction opposite to the rotation direction of the wing frame 10 with respect to the wind direction.

The wing movement guider 70 is hinged to the wind direction indicating member 60 extends in the form of an arc and functions to guide the moving wing 20 to move.

The wing movement guider 70 is hinged to the bent portion of the wind direction indicating member 60 and has a wide width of the guide body 71 and from the guide body 72 to the vicinity of the outer circumferential surface of the vertical axis of rotation 3. It is preferably composed of a narrow guide arm 72 extending.

The elastic body 80 is a function of pressing the wing movement guide 70 by the elastic main force is preferably installed to be coupled between the guide body 71 and the inclined plate material (63).

The elastic body 80 is pressed so that the end of the guide arm 72 toward the center of the vertical axis of rotation (3), that is, when the guide body 71 is pressed by the external force toward the inclined plate 72, the compression After the external force is removed, the guide arm 72 is pressed by the elastic restoring force to the original position in the center direction of the vertical rotation shaft 3.

On the other hand, in order to facilitate the movement of the moving wing 20 by the wing movement guider 70 of the above configuration, it is preferable that the openings 15 are formed at both side ends of the wing frame 10, which is the guide arm This is because the guide arm 72 must be in direct contact with the movable blade 20 for the guidance of 72.

In addition, both ends of the movable blade 20 are inclined so that the movable blade 20 can be easily guided by the guide arm 72 so that the contact area with the guide arm 72 is large. It is desirable to.

In addition, a means for compressing the elastic body 80 is required by pressing the guide body 71 of the wing movement guide 70 toward the inclined plate 63, for this purpose, the opening 15 of the wing frame 10 A pair of push protrusions 16 are formed to protrude in the rotational direction of the wing frame 10 on the upper and lower sides, and the separation interval of the pair of push protrusions 16 is wider than the width of the guide arm 72. It is preferable to correspond to the width of the guide body (71).

The push protrusion 16 inclines the guide body 72 as the wing frame 10 approaches the wing movement guider 70 and first faces the guide body 72 while the wing frame 10 rotates. The elastic body 80 is compressed by pushing toward the plate 62.

In addition, in order to smoothly move the wing 10, the wing frame 10 is preferably formed to be inclined downward toward both ends of the vertical rotation shaft 10, which is guided by the wing guide guide 70 In order to be able to be moved to the end by the gravity of the moving wing 20 in the last step of the movement when the moving wing 20 is moved from the wing frame 10 to the opposite direction from the wing frame 10 side to the reverse direction.

Referring to the operation of the movable rotary wing structure 2 according to another embodiment of the present invention made of a configuration as described above are as follows.

11 to 17 are planar cross-sectional views illustrating an operating state of the wing moving guider 70 and a moving state of the wing 20 according to the rotation of the wing frame 10.

As shown in FIG. 11, the wind direction indicating member 60 changes its position according to the wind direction so that the horizontal bar 61 is biased toward the opposite direction of rotation of the wing frame 10 than the position parallel to the wind direction. have.

In the state before the one-side wing frame 10a which rotates in the forward direction with respect to the wind direction, the wing move guider 70 is pressed by the elastic body 80 so that the end of the guide arm 72 is in the center direction of the vertical rotation axis 3. Maintain an extended state.

In this state, when one wing frame 10a that rotates forward approaches the wing mover 70 while rotating, the push protrusion 16 protruding from the wing frame 10a first guides as shown in FIG. 12. It comes into contact with the body 71.

And, as shown in Figure 13, the push protrusion 16 of the one wing frame (10a) is to push the guide body 71 toward the inclined plate (63). Accordingly, the wing movement guider 70 is rotated toward the inclined plate 63 to compress the elastic body 80.

And if the rotation of the wing frame 10 is to continue the push projection 16 passes through the guide body 63, at this time the width of the push projection 16 is wider than the width of the guide arm 72 The pushing force by the push protrusion 16 is removed.

Accordingly, as shown in FIG. 14, the wing moving guider 70 is pressed by the elastic restoring force of the elastic body 80, and thus the wing wing guide 70 is returned to its original position. Receives a pressure guide of the will start to move toward the opposite wing frame (10).

As shown in FIGS. 15 and 16, as the rotation progress of the wing frame 10 continues, the guide arm 72 gradually returns to the vicinity of the outer circumferential surface of the vertical rotation shaft 3 while the moving wing 20 is moved. You will be constantly guided to move.

And after the wing movement guider 70 is completely in place as shown in Figure 16, the inertia of the moving wing 20, the gravity action due to the downwardly inclined wing frame 10, of the wing frame 10 The movement of the movable blade 20 continues by centrifugal force due to rotation, thereby completing the movement to the opposite wing frame 10 completely.

When the one wing frame 10a that was previously rotated forward through the above-described operation process is converted to reverse rotation, as shown in FIG. 17, the moving wing 20 is converted to the other wing which is converted from the reverse rotation to the forward rotation. It is located on the frame 10b side, and thus the wing frame 10 is continuously subjected to only forward rotational force by the wind.

Although the present invention has been described above, the technical scope of the present invention is not limited to the contents described in the above-described embodiments, and equivalent configurations modified or changed by those skilled in the art may be described. It will be said that it does not go beyond the scope of thought.
