Description

Blade Angle Adjuster of Wind Power Generator

The present invention relates to a blade angle adjusting device of a wind power generator, and more particularly, to a blade angle adjusting device of a wind power generator having a structure in which the angle of the blade is rotatably adjusted in conjunction with an auxiliary wing that is freely rotated and aligned in a wind blowing direction. It is about.

In general, a wind turbine is a device for obtaining electrical energy by using natural wind, and has a blade for rotating the shaft to receive the wind, the vertical wind turbine of Korea Patent No. 485494, freely rotates in the wind blowing direction It has a structure to improve the wind power generation efficiency by adjusting the rotation of the blade in proportion to the rotation angle displacement of the auxiliary blade to be aligned.

The vertical wind power generator, as shown in Figure 1, the generator 2 is connected to the lower end of the main shaft (1), a plurality of upper connecting shafts (3) and lower radially from the main shaft (1) The connecting shaft 5 extends, and the blades 11 are respectively mounted between the upper connecting shaft 3 and the lower connecting shaft 5, and the blades 11 are provided through the wing front angle adjusting device 31. It has a structure connected to the auxiliary wing (7).

In the vertical wind generator having the configuration as described above, the auxiliary wing 7 is always aligned in a straight line in the direction of the wind blowing. Assuming that the wind blows in the X-axis direction, as shown in FIG. 2, the auxiliary wings 7 are always aligned in the X-axis direction, and the blade 11 is connected to the wing front angle adjuster 31. By the auxiliary wing 7 is arranged to have a constant angle in the wind portion direction and at the same time circumferential movement in the clockwise direction around the main shaft (1) by the wind.

That is, when the auxiliary blade (7) and the blade (11a) in the a position in the X-axis direction, and the blade is located in the b position in the circumferential motion (orbit), the auxiliary blade (7) to match the direction of the wind Rotates, and the blade 11b is inclined in the −45 ° direction with respect to the X axis by the wing front angle adjusting device 31 by the rotation angle of the auxiliary blade 7.

When the blade 11b further rotates about the main shaft 1 to reach the c position, the auxiliary wing 7 is rotated to coincide with the direction of the wind, so that the wing front angle adjusting device 31 is rotated. The angle of rotation of the blade 7 is transmitted to the blade 11c so that the blade 11c is rotated by -90 ° to be perpendicular to the direction of the wind, and the auxiliary wing 7 and the wing front angle adjusting device at the d position ( 31), the blade 11d is disposed at an angle of -125 ° with respect to the direction of the wind.

Therefore, by the blade front angle adjusting device 31 which transmits the angular rotation of the auxiliary blade 7 to the blade, the blade 11 always carries the wind and circumferentially moves in one direction with a large rotation moment. As the main shaft 1 rotates due to the circumferential motion, the generator 2 arranged at the lower end of the main shaft 1 is generated.

In the prior art, the blade front angle adjusting device 31, which allows the blade 11 to be disposed in front with respect to the wind blowing direction, as shown in FIG. ) Has a structure in which the upper shaft 35 having a mounting hole 33 and the lower shaft 41 are connected to the gear reducer 51 so that the gear reducer 51 can be mounted, and the gear reducer 51 has an upper shaft 35. The planetary gear 53 and the lower shaft 41 are mounted on the lower end of the planetary gear 53 to be engaged with the planetary gear 53 in a state of being connected to the planetary gear 53.

The upper shaft 35 and the planetary gear 53 are rotated by angular rotation so that the auxiliary blades are in line with the wind direction, and the sun gear 55 and the sun gear 55 meshed with the planetary gear 53 are rotated. The lower shaft 41 is linked to rotate, the blade 11 is connected to the connecting member 17 mounted on the lower end of the lower shaft 41 to rotate each.

In order to adjust the blade 11 so that the blade 11 is always disposed in front of the wind direction by the above operating principle, the circumferential motion and rotation ratio of the blade 11 is preferably 2: 1. In order to make the ratio of the circumferential motion and the rotation of the blade 11 to be 2: 1, the rotation ratio of the planetary gear 53 and the sun gear 55 of the gear reducer 51 can be kept constant 2: 1 in the same direction. Should be

Applying an internal gear structure consisting of a ring-shaped internal gear and an external gear that is rotated in engagement with the internal gear, the simple internal structure of one internal gear and one external gear makes the internal gear and the external gear inscribed. Since the external gears can be stably rotated in the same direction as each other, conventionally, an internal gear structure is applied to a large-capacity wind power generator to realize the above rotation ratio.

Conventionally, the rotation ratio transmission unit corresponding to the gear reducer 51 is implemented by using one internal gear and one external gear, but the above rotation ratio is realized. However, the external gear is installed in an eccentric state away from the center of the internal gear. The connection between the gear and the external gear is made only in a narrow part of the inner circumference of the internal gear, and the external gear is easily moved to the free space portion inside the internal gear.

Accordingly, even if a minute degree of relative displacement occurs between the auxiliary blades 7 to the upper shaft 35 and the blades 11 to the lower shaft 41 due to the difference in wind strength and direction, the internal gear and It is difficult to clearly transmit the rotational displacement of the external gear to the internal gear because the interference or play between the external gear is easily generated.In the case of the gear teeth being worn out due to continuous use or strong wind, the rotational displacement and rotational force transmission efficiency of the rotational displacement transmission unit is rapidly increased. There was a problem of deterioration.

In this case, the blade does not interlock with the auxiliary blades quickly and at a predetermined angle, but also interferes with the movement of other blades and interferes with the idle state of the entire blades. As the interference and play between the internal gear and the external gear occur to different degrees, there is another problem that the wind power generation efficiency is greatly reduced.

In addition, the internal gear has a significantly higher manufacturing cost than the external gear due to its difficult processing and manufacturing. In the case of a small-capacity wind turbine, the rotation angle displacement and rotational force of the auxiliary blade can be stably transmitted to the blade side without applying the internal gear as described above. In addition, since wind power generation can be efficiently implemented, development of a structure that can be implemented at a lower cost is required.

The present invention devised to solve the problems as described above, by implementing a rotation displacement transmission unit structure that can reliably transfer the rotational displacement of the auxiliary blade to the blade, by using one internal gear and one external gear It is an object of the present invention to provide a blade angle adjusting device of a wind power generator, which can solve the interference phenomenon between blades caused by transmitting rotational displacement and rotational force of the auxiliary blade to the blade.

Accordingly, the sun gear 210 does not move to an arbitrary position inside the ring gear 220 due to a difference in wind strength and direction, and thus the relative position between the sun gear 210 and the ring gear 220. While maintaining the constant, it is possible to clearly and reliably transmit the rotation angle displacement or rotational force of the sun gear 210 and the auxiliary wing 7 to the ring gear 220 and the blade 11.

In addition, by freely pulling the wire member 641 coupled to the rotational fork 630 to the rotational force transmission means 640 toward the main shaft 1 side, the rotational force transmission arm 632 of the rotational fork is free. The rotation angle displacement of the pivoting fork 630 can be constantly adjusted so that an end thereof is positioned on the same horizontal extension line as the fork pivoting shaft 620 which is the pivotal center of the pivoting fork 630, and the wire member According to the degree of pulling the 641, the detachable degree of the clutch unit 500 is not changed, it is possible to stably adjust the detachable operation state of the clutch unit 500.
