Description

[Technical Field]

[0001] The present invention relates to a speed control device, and more particularly to a speed control device for controlling the constant speed rotation of an idler wheel of a wind turbine generator. [Background technology]

[0002] Currently, there are power supply mechanisms on the market that combine wind power generation with an idler-related system, which generate electricity by rotating the idler and synchronously operating the main shaft of the generator, and output the electricity to the outside, thereby achieving the goal of obtaining electricity in a relatively environmentally friendly way. However, wind power generation has problems such as being unable to generate electricity normally for a certain period of time due to no wind or unstable wind force or wind direction. Due to these factors, the idler wheel of the power supply mechanism may not rotate at a constant speed, or its speed may gradually decrease, or even stop rotating, which may cause the main shaft of the generator to no longer rotate at a constant speed, resulting in the problem of being unable to output electricity normally.

When the wind turbine of the wind power generation unit is driven by wind power equal to or greater than a preset wind power value, a wind start gear group is driven by the wind turbine to operate and rotate. When the wind power is lower than the preset wind power value, a rack unit on a speed control motor of the first speed control unit is driven by power, the speed control gear group of the first speed control unit is driven by a first one-way gear of the first speed control unit, and the transmission gear group is driven by a second one-way gear of the second speed control unit, causing the transmission gear group to rotate for a certain period of time, so that the idler wheel of the idler energy storage unit drives the main shaft of the generator of the idler energy storage unit to rotate at a constant speed (uniform speed), preventing the idler wheel in the power supply mechanism from gradually slowing down or even stopping.

DETAILED DESCRIPTION OF THE INVENTION

[0007] Referring to FIG. 1, the present invention provides a speed control device 1 for controlling the constant speed rotation of an idler wheel of a wind power generator, and the speed control device 1 includes a wind power generation unit 10, a first speed control unit 20, a transmission gear group 30, an idler energy storage unit 40 and a second speed control unit 50.

[0008] 1, 8, 9 and 11, the wind power generating unit 10 includes a wind turbine 11 and a wind start gear set 12. When the wind turbine 11 is driven by wind power equal to or greater than a preset wind power value, the wind start gear set 12 is driven by the wind turbine 11 to operate and rotate.

[0009] The first speed control unit 20 includes a speed control motor 21 (see FIG. 1), a rack unit 22 (see FIG. 1), a first swing arm 23 (see FIG. 1), a spring 24 (see FIG. 1), a frame 25 (see FIG. 1), a speed control gear group 26 (see FIG. 1), a first one-way bearing 27 (see FIG. 5), and a first one-way gear 28 (see FIG. 5). The rack unit 22 is located on the speed control motor 21 and can be driven by the speed control motor 21. The rack unit 22 includes a clutch 221, a rack gear group 222, a link rack gear 224, a rack 225, a damper 226, an upper clutch switch 227, and a lower clutch switch 228 (see FIG. 6). The clutch 221 can drive the rack gear group 222, and the rack gear group 222 can drive the link rack gear 224, and the link rack gear 224 moves the rack 225 downward (see FIG. 7). The rack 225 has an upper starting portion 2251 and a lower starting portion 2252 (see FIG. 7). The upper clutch switch 227 and the lower clutch switch 228 are respectively provided at the upper and lower ends of the damper 226 (see FIG. 7) and are located between the upper starting portion 2251 and the lower starting portion 2252 of the rack 225 (see FIG. 7). When the speed control motor 21 drives the clutch 221, the clutch 221 starts to drive the rack gear group 222, the link rack gear 224, and the rack 225 in order, thereby moving the rack 225 downward (see FIG. 6).One end of the spring 24 is attached to the frame 25 (see FIG. 1), and the other end of the spring 24 is attached to the first swing arm 23 (see FIG. 5). The speed control gear group 26, the first one-way bearing 27, and the first one-way gear 28 are located at the same end of the first swing arm 23 (see FIG. 5). The speed control motor 21, the rack unit 22, and the spring 24 are located at the other end of the first swing arm 23 opposite the speed control gear group 26, the first one-way bearing 27, and the first one-way gear 28 (see FIG. 5). The speed control gear group 26 can be driven by the first one-way gear 28, and the first one-way gear 28 is attached to the first one-way bearing 27 and can rotate for a certain period of time when driven (see FIG. 7). When the speed control motor 21 is driven by electricity, the clutch 221 of the rack unit 22 is driven and rotated by the speed control motor 21, and the first swing arm 23 is pressed down by the rack unit 22 (indicated in the direction of arrow A in FIG. 6), generating a first pressing force N to drive the first one-way bearing 27 and rotate the first one-way gear 28 for a certain period of time as shown in FIG. 6. At this time, the speed control gear group 26 rotates following the first one-way gear 28 for a certain period of time. When the first swing arm 23 releases the pressing force N from the rack 225 of the rack unit 22, the first swing arm 23 returns to its original position due to the elastic restoring stress of the spring 24. At this time, the clutch 221 is in a state where it temporarily stops driving the rack gear group 222 and the link rack gear 224, and the rack gear group 222 and the link rack gear 224 are allowed to rotate freely in the rotational direction without any restrictions. Therefore, the rack 225 is pushed upward by the first swing arm 23 (indicated in the direction of arrow D in FIG. 5 ) and returns to its original position until the lower starting part 2252 triggers the lower clutch switch 228 to cause the speed control motor 21 to start supplying power to the clutch 221.

[0010] The transmission gear group 30 can be driven to operate and rotate by the wind power starting gear group 12 (see FIGS. 9 to 12) or the speed control gear group 26 (see FIGS. 12 to 14).

[0011] As shown in FIGS. 13 and 15, the idler energy storage unit 40 includes an idler wheel 41, an idler gear group 42, a generator main shaft gear 43, a generator main shaft 44, and a generator 45. The idler wheel 41 can be driven to rotate by the idler gear group 42, and after rotating the idler wheel 41, the idler gear group 42 can be caused to rotate for a certain period of time. The generator main shaft gear 43 can be driven to rotate by the idler gear group 42. The generator main shaft 44 rotates in synchronization with the generator main shaft gear 43. The generator 45 generates electric power by rotating the idler wheel 41 for a certain period of time and outputs the generated electric power to the outside (see FIGS. 13 and 15). When the idler wheel 41 rotates, the idler gear group 42 drives the generator main shaft gear 43 and the generator main shaft 44 to rotate synchronously for a certain period of time, and as shown in Figures 13 and 15, the generator 45 can generate electricity by the rotation of the generator main shaft 44. The generator 45 is electrically connected to the speed control motor 21 as shown in Figure 1. When the wind force received by the wind turbine 11 is lower than a preset wind force value, the generator 45 supplies power to the speed control motor 21 to drive the speed control motor 21 and operate as shown in Figure 1.

[0012] The second speed control unit 50 includes a second swing arm 51 (see FIG. 1), a mounting base 52 (see FIG. 1), a second one-way bearing 54 (see FIG. 1), and a second one-way gear 53 (see FIG. 5). One end of the second swing arm 51 is attached to the speed control gear group 26 as shown in FIG. 5, and the mounting base 52 is attached to the other end of the second swing arm 51 relative to the speed control gear group 26 as shown in FIG. 5. The second one-way bearing 54 and the second one-way gear 53 are attached to the other end of the second swing arm 51 opposite to the mounting base 52 as shown in FIG. 5. The second one-way gear 53 can drive the transmission gear group 30 as shown in FIG. 5. The second one-way gear 53 is attached to the second one-way bearing 54 as shown in FIG. 5, and can rotate for a certain period of time when driven. As shown in Fig. 5, the second swing arm 51 and the mounting table 52 are supported and suspended by the speed control gear group 26, and the mounting table 52 is driven by the speed control gear group 26 to move upward as shown by arrow B in Fig. 7. After the first swing arm 23 returns to its original position due to the elastic restoring stress of the spring 24 as shown in Fig. 5, the second swing arm 51 is pressed down by the weight of the object placed on the mounting table 52 (as shown by arrow C in Fig. 5) and returns to its original position, generating a second pressing force n to drive the second one-way bearing 54 and rotate the second one-way gear 53 for a certain period of time as shown in Fig. 5. At this time, the transmission gear group 30 rotates following the second one-way gear 53 for a certain period of time as shown in Fig. 5.

[0013] The speed control motor 21, the clutch 221, the rack gear group 222, the link rack gear 224, and the damper 226 are disposed on the mounting table 52 (see FIGS. 4 and 5). After the first swing arm 23 returns to its original position due to the elastic recovery stress of the spring 24, the second swing arm 51 is pushed down by the weight of the speed control motor 21 and the rack unit 22 to return to its original position (in the direction of arrow C in FIG. 5). A second pushing force n is then generated to drive the second one-way bearing 54 and cause the second one-way gear 53 to rotate for a certain period of time (see FIG. 5). At this time, the transmission gear group 30 rotates for a certain period of time following the second one-way gear 53. The second swing arm 51 and the mounting table 52 are driven upward by the speed control gear group 26 to which driving force is provided by the speed control motor 21 (in the direction of arrow B in FIG. 7). At this time, the upper clutch switch 227 of the damper 226 is pushed upward until the upper starting portion 2251 of the rack 225 triggers the upper clutch switch 227 and causes the speed control motor 21 to stop supplying power to the clutch 221 (see FIG. 7).

[0014] When the transmission gear group 30 is driven to rotate, the idler gear group 42 is driven by the transmission gear group 30 to rotate, as shown in FIG. 15, and the idler wheel 41 rotates following the idler gear group 42. Then, as shown in FIG. 15, the idler gear group 42, the generator main shaft gear 43, and the generator main shaft 44 are rotated for a certain period of time to maintain a constant speed state.

[0015] When the wind turbine 11 is driven by wind power equal to or greater than the preset wind power value, the wind start gear group 12 operates and rotates to drive the transmission gear group 30 as shown in FIG. 18, and the idler gear group 42, the generator main shaft gear 43, and the generator main shaft 44 are driven by the idler wheel 41, and rotate for a certain period of time as shown in FIG. 15 to maintain a constant speed.

[0016] When the wind force received by the wind turbine 11 is lower than the preset wind force value, the rack unit 22 on the speed control motor 21 receives power and is driven, the speed control gear group 26 is driven by the first one-way gear 28, and the transmission gear group 30 is driven by the second one-way gear 53, so that the transmission gear group 30 rotates for a certain period of time as shown in FIG. 15, and when the wind force is insufficient for the idler wheel 41, the idler gear group 42, the generator main shaft gear 43, and the generator main shaft 44 are driven to rotate for a certain period of time, so as to maintain a constant speed state as shown in FIG. 15.

[0017] 2, the rack gear group 222 includes, but is not limited to, a plurality of gears 222a, 222b, 222c, and 222d. After the gear 222a rotates, it sequentially drives the gears 222b, 222c, and 222d, and finally the gear 222d drives the link rack gear 224, as shown in FIG. 2. The link rack gear 224 further includes, but is not limited to, a bearing 223.

[0018] 20 and 21, the first swing arm 23 further includes, but is not limited to, a first horseshoe-shaped clamp 29, and as shown in FIG. 14, the speed control gear group 26, the first one-way bearing 27, and the first one-way gear 28 are disposed at the same end of the first swing arm 23. The first one-way bearing 27 and the first one-way gear 28 are further disposed within the first horseshoe-shaped clamp 29 of the first swing arm 23.

[0019] 22 and 23 , the second swing arm 51 further includes, but is not limited to, a second horseshoe-shaped clamp 55, and the second one-way bearing 54 and the second one-way gear 53 are disposed at the same end of the second swing arm 51. The second one-way bearing 54 and the second one-way gear 53 are further disposed within the second horseshoe-shaped clamp 55 of the second swing arm 51.

[0020] Referring to Fig. 10, the wind starting gear group 12 is composed of, but not limited to, a plurality of gears 12a, 12b, 12c, 12d, 12e, and 12f, and as shown in Figs. 18 and 19, at least one gear has a bearing 121. After the gear 12a rotates, it drives the gear 12b (see Fig. 10), the gear 12b drives the gear 12c (see Fig. 10), the gear 12c drives the gear 12d (see Fig. 10), the gear 12e drives the gear 12f (see Fig. 10), and finally the gear 12f drives the transmission gear group 30 (see Figs. 18 and 19).

[0021] 5, the speed control gear group 26 is composed of a plurality of gears 26a and 26b, but is not limited thereto, and as shown in FIG. 16, at least one of the gears has a bearing 261. After the gear 26a rotates, it drives the gear 26b, and finally, the gear 26b drives the second one-way gear 53 as shown in FIG.

[0022] 13, the transmission gear group 30 is composed of, but not limited to, a plurality of gears 30a, 30b, 30c, 30d, 30e, 30f, and 30g, and at least one gear has a bearing 301 as shown in FIG. 17. After the gear 30a rotates, it drives the gear 30b, which drives the gear 30c, which drives the gear 30d, which drives the gear 30e, which drives the gear 30f, and finally, the gear 30g drives the idler gear group 42 as shown in FIGS. 9 and 11.

[0023] 15, the idler gear group 42 is composed of a plurality of gears 42a and 42b, but is not limited thereto, and as shown in FIG. 17, at least one of the gears has a bearing 421. After the gear 42a rotates, it drives the gear 42b, and finally, the gear 42b drives the generator main shaft gear 43 as shown in FIG.

[0024] 11 and 18, when the wind turbine 11 is driven by wind power equal to or greater than the preset wind power value, the gear 12f of the wind start gear group 12 is operated and rotated to drive the gear 30a of the transmission gear group 30, and the gear 30g of the transmission gear group 30 drives the gear 42a of the idler gear group and the idler wheel 41. The idler wheel 41 causes the gear 42b to drive the generator main shaft gear 43 and the generator main shaft 44 to rotate for a certain period of time (see FIG. 15). When the wind force acting on the wind turbine 11 is lower than the preset wind force value, the rack unit 22 of the speed control motor 21 is driven by electric power, the gear 26a of the speed control gear group 26 is driven by the first one-way gear 28, and the gear 30a of the transmission gear group 30 is driven by the second one-way gear 53, causing the transmission gear group 30 to rotate for a certain period of time (see FIG. 15). Thereafter, the gear 30g of the transmission gear group 30 can drive the gear 42a of the idler gear group 42 and the idler wheel 41, and the idler wheel 41 can cause the idler gear group 42, the generator main shaft gear 43, and the generator main shaft 44 to rotate for a certain period of time and maintain a constant speed when the wind force is insufficient (see FIG. 15).

[0025] 1, the speed control motor 21 of the first speed control unit 20 is electrically connected to a generator 45 via an electric wire 60. The speed control device 1 further includes a control unit 70 disposed between the speed control motor 21 and the generator 45, and the control unit 70 controls the generator 45 to supply power to the speed control motor 21 to operate the speed control motor 21 when the wind force received by the wind turbine 11 is lower than a preset wind force value.

[0026] When the rack unit 22 is in use, the rack 225 pushes the first swing arm 23 downward, rather than pushing the first swing arm 23 downward while rotating using a structure, thereby reducing noise generated during operation of the device. In addition, by using the rack 225 to push the first swing arm 23 downward, it is possible to avoid a problem in which the swing arm cannot be pushed due to insufficient force when rotating a structure.

[0027] In summary, in wind power generation, depending on the presence or absence of wind, unstable wind force or wind direction, the idler wheel in the power supply mechanism will gradually reduce its rotation speed and even stop rotating. To solve this drawback of the conventional power supply mechanism, in the present invention, when the wind force received by the wind turbine 11 is lower than a preset wind force value, as shown in the figure, the rack unit 22 on the speed control motor 21 is driven by electricity to cause the speed control gear group 26 to drive the first one-way gear 28, and the transmission gear group 30 to drive the second one-way gear 53, causing the transmission gear group 30 to rotate for a certain period of time. In addition, when the wind force is insufficient, the idler wheel 41 can maintain a certain speed by causing the idler gear group 42, the generator main shaft gear 43, and the generator main shaft 44 to rotate for a certain period of time, as shown in the figure.

[0028] The above description is a preferred embodiment showing the technical features of the present invention, and those skilled in the art can make changes and modifications without departing from the spirit of the present invention, and these changes and modifications are included in the scope of the claims of the present invention.
