Description

Technical Field

[0001] This utility model relates to a speed control device, and more particularly to a speed control device for controlling the uniform rotation of a flywheel in a wind power generation system. Background Technology

[0002] Currently, there is a type of power supply mechanism on the market that combines wind power generation with a flywheel system. This mechanism generates electricity by using the rotation of the flywheel to synchronize the operation of the generator's main shaft, thus achieving a relatively environmentally friendly way to obtain electricity. However, wind power generation is subject to problems such as the presence or absence of wind, unstable wind force, or wind direction, which can lead to periods of inability to generate electricity normally. These factors can cause the flywheel in the power supply mechanism to not rotate at a constant speed, to gradually slow down, or even stop rotating. This, in turn, causes the generator's main shaft to not rotate at a constant speed, to gradually slow down, or even stop operating, resulting in a failure to output electricity normally. Therefore, a flywheel speed control device has emerged on the market that can control the wind turbine's flywheel to achieve constant speed rotation or further prevent the flywheel in the power supply mechanism from gradually slowing down or even stopping.

[0003] Among existing flywheel speed control devices, there is a speed control device for controlling the uniform rotation of a wind turbine flywheel, including a wind power generation unit, a first speed control unit, a transmission gear set, a flywheel energy storage unit, and a second speed control unit. When the wind turbine of the wind power generation unit is driven by a preset or higher wind force value, the wind turbine starting gear set is driven by the wind turbine to operate and rotate. When the wind force is lower than the preset or higher wind force value, the cam on the speed control motor of the first speed control unit is driven by electricity, causing the speed control gear set of the first speed control unit to be driven by the first one-way gear of the first speed control unit, and the transmission gear set to be driven by the second one-way gear of the second speed control unit, so that the transmission gear set rotates for a period of time, so that the flywheel of the flywheel energy storage unit can drive the generator main shaft of the flywheel energy storage unit to rotate at a uniform speed (uniform rotation speed), thereby avoiding the situation where the flywheel in the power supply mechanism gradually slows down or even stops rotating.

[0004] However, the speed control device still has the following drawbacks that require improvement:

[0005] (1) Noise generation: When the cam is in operation, the pushing structure will produce a loud noise, which will cause noise interference to the surrounding environment.

[0006] (2) Insufficient power: When the cam initially receives power and starts to operate, it is relatively weak, which can easily cause the structure to be unable to push the rocker arm due to insufficient power when rotating and pushing.

[0007] As can be seen from the above shortcomings, the existing flywheel speed control device does indeed need to be improved. Utility Model Content

[0008] The main objective of this invention is to provide a speed control device for controlling the uniform rotation of a flywheel in a wind power generation system. The device includes a wind power generation unit, a first speed control unit, a transmission gear set, a flywheel energy storage unit, and a second speed control unit. When the wind turbine of the wind power generation unit is driven by a preset or higher wind force value, the wind turbine starting gear set is driven by the wind turbine to rotate. When the wind force is lower than the preset or higher wind force value, the rack unit on the speed control motor of the first speed control unit is electrically driven, causing the speed control gear set of the first speed control unit to be driven by the first one-way gear of the first speed control unit, and the transmission gear set to be driven by the second one-way gear of the second speed control unit. This causes the transmission gear set to rotate for a period of time, enabling the flywheel of the flywheel energy storage unit to drive the generator main shaft of the flywheel energy storage unit to rotate at a uniform speed (uniform rotational speed), thus preventing the flywheel in the power supply mechanism from gradually slowing down or even stopping.

[0009] To achieve the above objectives, this utility model provides a speed control device for controlling the uniform rotation of a flywheel in a wind power generation system. The speed control device includes a wind power generation unit, a first speed control unit, a transmission gear set, a flywheel energy storage unit, and a second speed control unit. The wind power generation unit includes a wind turbine and a wind-driven starting gear set. When the wind turbine is driven by a preset or higher wind force value, the wind-driven starting gear set is driven by the wind turbine to rotate. The first speed control unit includes a speed control motor, a rack unit, a first rocker arm, a spring, a frame, a speed control gear set, a first one-way bearing, and a first one-way gear. The rack unit is located within the... The speed control motor drives the rack unit, which includes a clutch, a rack and pinion gear set, a connecting rack and pinion gear, a rack, a shock absorber, an upper clutch switch, and a lower clutch switch. The clutch drives the rack and pinion gear set, which in turn drives the connecting rack and pinion gear, causing the rack to move downwards. The rack has an upper actuation part and a lower actuation part. The upper and lower clutch switches are located at the upper and lower ends of the shock absorber, respectively, and are situated between the upper and lower actuation parts of the rack. When the speed control motor drives the clutch, the clutch engages and sequentially drives the rack and pinion gear. The rack and pinion assembly, the connecting rack and pinion, and the rack cause the rack to move downwards. One end of the spring is mounted on the frame, and the other end is mounted on the first rocker arm. The speed control gear assembly, the first one-way bearing, and the first one-way gear are located at the same end of the first rocker arm. The speed control motor, the rack unit, and the spring are located at the other end of the first rocker arm relative to the speed control gear assembly, the first one-way bearing, and the first one-way gear. The speed control gear assembly can be driven by the first one-way gear, which is mounted on the first one-way bearing and can rotate for a period of time when driven. When the speed control motor is driven by electricity, the clutch of the rack unit is engaged by the speed control motor. The motor drives the first rocker arm to rotate, causing the rack of the rack unit to press down and displace, generating a first downward force that drives the first one-way bearing to rotate the first one-way gear for a period of time. During this time, the speed control gear set follows the first one-way gear to rotate for a period of time. When the first rocker arm releases the downward force from the rack of the rack unit, the first rocker arm returns to its original position by the elastic restoring stress of the spring. At this time, the rack is pushed upward by the first rocker arm back to its original position until the lower starting part triggers the lower clutch switch, causing the speed control motor to start and supply power to the clutch. The transmission gear set can be driven to rotate by the wind-powered starting gear set or the speed control gear set.The flywheel energy storage unit includes a flywheel, a flywheel gear set, a generator main shaft gear, a generator main shaft, and a generator. The flywheel is driven by the flywheel gear set to rotate, and its rotation drives the flywheel gear set to rotate for a period of time. The generator main shaft gear is driven by the flywheel gear set to rotate, and the generator main shaft rotates synchronously with the generator main shaft gear. The generator generates electricity and outputs it externally through the operation of the generator main shaft. When the flywheel rotates, the flywheel gear set drives the generator main shaft gear and the generator main shaft to rotate synchronously for a period of time, enabling the generator to generate electricity. The main shaft operates to generate electricity, and the generator is electrically connected to the speed control motor. When the wind force on the wind turbine is lower than or higher than a preset wind force value, the generator supplies power to the speed control motor to drive it. The second speed control unit includes a second rocker arm, a support platform, a second one-way bearing, and a second one-way gear. One end of the second rocker arm is mounted on the speed control gear set, and the support platform is mounted on the other end of the second rocker arm relative to the speed control gear set. The speed control motor, the clutch, the rack and pinion gear set, the connecting rack and pinion gear, and the shock absorber are mounted on the support platform. The second one-way bearing and the second one-way gear are... The second one-way gear, mounted on the support platform at the other end of the second rocker arm, drives the transmission gear set. The second one-way gear is mounted on the second one-way bearing and can rotate for a period of time when driven. The second rocker arm and the support platform are supported and suspended by the speed control gear set and can be driven upwards by the speed control gear set. When the first rocker arm returns to its original position due to the elastic restoring stress of the spring, the second rocker arm, under the weight of the speed control motor and the rack unit, is pushed back to its original position, further generating a second downward force to drive the second one-way bearing, causing the second one-way gear to rotate for a period of time. During this time, the transmission gear set follows the second one-way bearing... The gear rotates for a period of time, wherein when the second rocker arm and the support platform are driven upward by the speed control gear set driven by the speed control motor, the upper clutch switch of the shock absorber is pushed upward until the upper starting part of the rack triggers the upper clutch switch, causing the speed control motor to stop supplying power to the clutch; wherein the speed control motor is further mounted on the support platform; wherein when the transmission gear set is driven to rotate, the flywheel gear set is driven to rotate by the transmission gear set, so that after the flywheel follows the operation and rotation of the flywheel gear set, it can drive the flywheel gear set, the generator main shaft gear, and the generator main shaft to rotate for a period of time;When the wind turbine is driven by a wind force of at least or greater than the preset value, the wind-driven starting gear set rotates, driving the transmission gear set. This causes the flywheel gear set, the generator main shaft gear, and the generator main shaft to rotate for a period of time. When the wind force on the wind turbine is less than the preset value, the rack unit on the speed control motor is electrically driven, causing the speed control gear set to rotate under the influence of the first one-way gear, and the transmission gear set to rotate under the influence of the second one-way gear. This allows the flywheel to drive the flywheel gear set, the generator main shaft gear, and the generator main shaft to rotate at a constant speed during periods of insufficient wind, preventing the flywheel's speed from gradually decreasing or even stopping.

[0010] In a preferred embodiment of the present invention, the speed control motor of the first speed control unit is further electrically connected to the generator via a wire.

[0011] In a preferred embodiment of the present invention, the speed control device further includes a control unit, which is located between the speed control motor and the generator; wherein the control unit is configured to enable the generator to provide power to the speed control motor to drive the speed control motor to operate when the wind force received by the wind turbine is lower than the preset or higher wind force value.

[0012] In a preferred embodiment of the present invention, the clutch switch and the lower clutch switch are further electrically connected to a control unit via a wire; wherein when the upper start unit triggers the upper clutch switch, the control unit further stops the speed control motor from supplying power to the clutch; wherein when the lower start unit triggers the lower clutch switch, the control unit further supplies power to the clutch via the speed control motor.

[0013] In a preferred embodiment of the present invention, the first rocker arm further includes a first horseshoe-shaped clamp, and the first horseshoe-shaped clamp is located at the same end of the first rocker arm as the speed control gear set, the first one-way bearing and the first one-way gear; wherein the first one-way bearing and the first one-way gear are further disposed within the first horseshoe-shaped clamp of the first rocker arm.

[0014] In a preferred embodiment of the present invention, the second rocker arm further includes a second horseshoe-shaped clamp, and the second horseshoe-shaped clamp is located at the same end of the second rocker arm as the second one-way bearing and the second one-way gear; wherein the second one-way bearing and the second one-way gear are further disposed within the second horseshoe-shaped clamp of the second rocker arm.

[0015] The advantage of this invention is that when the wind force received by the wind turbine of this invention is lower than the preset or higher wind force value, the rack unit on the speed control motor is driven by electricity, causing the speed control gear set to be driven by the first one-way gear and the transmission gear set to be driven by the second one-way gear, so that the transmission gear set rotates for a period of time, so that the flywheel can drive the flywheel gear set, the generator main shaft gear, and the generator main shaft to rotate for a period of time and maintain a uniform speed during a period of insufficient wind force.

The speed control device 1 includes a wind power generation unit 10, a first speed control unit 20, a transmission gear set 30, a flywheel energy storage unit 40, and a second speed control unit 50.

[0042] The wind power generation unit 10 includes a wind turbine 11 and a wind-powered starting gear set 12, as shown below. Figure 1 , 8 As shown in Figures 9 and 11, when the wind turbine 11 is driven by a wind force of a preset or higher value, the wind turbine starting gear set 12 is driven by the wind turbine 11 to rotate.

[0043] The first speed control unit 20 includes a speed control motor 21 (such as...). Figure 1 As shown), a rack unit 22 (as shown) Figure 1 As shown), a first pendulum rod 23 (as shown) Figure 1 As shown), a spring 24 (as shown) Figure 1 As shown), a frame 25 (such as Figure 1 As shown), a speed control gear set 26 (such as...) Figure 1 As shown), a first one-way bearing 27 (as shown) Figure 5 (as shown) and a first one-way gear 28 (as shown) Figure 5 As shown), 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 and pinion gear set 222, a connecting rack and pinion gear 224, a rack 225, a shock absorber 226, an upper clutch switch 227, and a lower clutch switch 228 (as shown). Figure 6 (As shown); wherein the clutch 221 can drive the rack and pinion set 222, the rack and pinion set 222 can drive the connecting rack and pinion 224, and the connecting rack and pinion 224 can drive the rack 225 to move downward (as shown). Figure 7 As shown), the rack 225 has an upper actuation part 2251 and a lower actuation part 2252 (as shown). Figure 7 As shown), the upper clutch switch 227 and the lower clutch switch 228 are respectively located at the upper and lower ends of the shock absorber 226 (as shown). Figure 7 As shown), and the upper clutch switch 227 and the lower clutch switch 228 are located between the upper actuation part 2251 and the lower actuation part 2252 of the rack 225 (as shown). Figure 7 As shown); wherein, when the speed control motor 21 drives the clutch 221, the clutch 221 is activated and sequentially drives the rack and pinion set 222, the connecting rack and pinion 224, and the rack 225, causing the rack 225 to move downward (as shown). Figure 6 As shown); one end of the spring 24 is mounted on the frame 25 (as shown). Figure 1 As shown), the other end of the spring 24 is located on the first rocker arm 23 (as shown). Figure 5 As shown), the speed control gear set 26, the first one-way bearing 27, and the first one-way gear 28 are located at the same end of the first rocker arm 23 (as shown). Figure 5 As shown), the speed control motor 21, the rack unit 22, and the spring 24 are located at the other end of the first rocker arm 23 relative to the speed control gear set 26, the first one-way bearing 27, and the first one-way gear 28 (as shown). Figure 5 As shown), the speed control gear set 26 can be driven by the first one-way gear 28, which is mounted on the first one-way bearing 27 and can rotate for a period of time when driven (e.g. Figure 7As shown); where, when the speed control motor 21 is driven by electricity, the clutch 221 of the rack unit 22 is driven by the speed control motor 21 to rotate, causing the first rocker arm 23 to be displaced by the downward pressure of the rack 225 of the rack unit 22 (as shown). Figure 6 (As indicated by arrow A in the diagram) This generates a first downward pressure N, driving the first one-way bearing 27 and causing the first one-way gear 28 to rotate for a period of time (as shown by arrow A in the diagram). Figure 6 As shown), at this time, the speed control gear set 26 follows the first one-way gear 28 to rotate for a period of time; when the first rocker arm 23 releases the downward pressure N from the rack 225 of the rack unit 22, the first rocker arm 23 returns to its original position by the elastic restoring stress of the spring 24. At this time, since the clutch 221 is in a state of temporarily stopping the drive of the rack and gear set 222 and the connecting rack and gear 224, the rack and gear set 222 and the connecting rack and gear 224 can rotate freely without being restricted by the direction of rotation. Therefore, the rack 225 is pushed upward by the first rocker arm 23 (as shown). Figure 5 (As indicated by arrow D in the image) Return to the original position until the lower starter 2252 triggers the lower clutch switch 228, causing the speed control motor 21 to start and supply power to the clutch 221 (as shown by arrow D in the image).

The generator main shaft gear 43 is driven to rotate by the flywheel gear set 42, and the generator main shaft 44 rotates synchronously with the generator main shaft gear 43. The generator 45 generates electricity and outputs it externally by means of the rotation of the flywheel 41 for a period of time (e.g., Figure 13 and Figure 15 As shown); when the flywheel 41 rotates, the flywheel gear set 42 drives the generator main shaft gear 43 and the generator main shaft 44 to rotate synchronously for a period of time, so that the generator 45 can generate electricity by means of the rotation of the generator main shaft 44 (e.g. Figure 13 and Figure 15 As shown); wherein the generator 45 is electrically connected to the speed control motor 21 (as shown). Figure 1(As shown); where, when the wind force received by the wind turbine 11 is lower than or higher than the preset wind force value, the generator 45 will provide power to the speed control motor 21 to drive the speed control motor 21 to operate (e.g. Figure 1 (As shown).

[0046] The second speed control unit 50 includes a second rocker arm 51 (e.g., ... Figure 1 As shown), a support platform 52 (as shown) Figure 1 As shown), a second one-way bearing 54 (as shown) Figure 1 (as shown) and a second one-way gear 53 (as shown) Figure 5 As shown), one end of the second rocker arm 51 is mounted on the speed control gear set 26 (as shown).

Figure 5 As shown), the second one-way gear 53 is capable of driving the transmission gear set 30 (as shown). Figure 5 As shown), the second one-way gear 53 is mounted on the second one-way bearing 54 and can rotate for a period of time when driven (e.g. Figure 5 As shown); wherein the second swing arm 51 and the support platform 52 are suspended in the air by the speed control gear set 26 (as shown). Figure 5 (As shown), and can cause the support platform 52 to be driven upward by the speed control gear set 26, as shown. Figure 7 As indicated by arrow B; where, after the first rocker arm 23 returns to its original position by the elastic restoring stress of the spring 24 (as shown in the image), Figure 5 As shown), the second pendulum 51 is displaced by the weight of the object placed on the support platform 52 (e.g., Figure 5 (As indicated by arrow C in the image) Returning to its original position, it further generates a second downward pressure n, driving the second one-way bearing 54 and causing the second one-way gear 53 to rotate for a period of time (as shown by arrow C in the image). Figure 5 As shown), at this time, the transmission gear set 30 follows the second one-way gear 53 to rotate for a period of time (as shown). Figure 5 (As shown).

[0047] The speed control motor 21, the clutch 221, the rack and pinion assembly 222, the connecting rack and pinion 224, and the shock absorber 226 are further mounted on the support platform 52 (e.g., Figure 4 and Figure 5 As shown); whereby, after the first rocker arm 23 returns to its original position by the elastic restoring stress of the spring 24, the second rocker arm 51 returns to its original position by the downward displacement of the speed control motor 21 and the rack unit 22 (as shown). Figure 5(As indicated by arrow C in the image) This further generates a second downward pressure n, driving the second one-way bearing 54 and causing the second one-way gear 53 to rotate for a period of time (as shown by arrow C in the image). Figure 5 As shown), at this time, the transmission gear set 30 follows the second one-way gear 53 to rotate for a period of time; wherein the second rocker arm 51 and the support platform 52 are driven upward by the speed control gear set 26 provided with driving force from the speed control motor 21 (as shown). Figure 7 (As indicated by arrow B in the diagram), at this time, the upper clutch switch 227 of the shock absorber 226 is pushed upward until the upper actuation part 2251 of the rack 225 triggers the upper clutch switch 227, causing the speed control motor 21 to stop supplying power to the clutch 221 (as shown by arrow B in the diagram). Figure 7 (As shown).

[0048] When the transmission gear set 30 is driven to rotate, the flywheel gear set 42 is driven to rotate by the transmission gear set 30 (e.g.) Figure 15 As shown), this allows the flywheel 41 to rotate following the operation of the flywheel gear set 42, thereby driving the flywheel gear set 42, the generator main shaft gear 43, and the generator main shaft 44 to rotate for a period of time and maintain a constant speed (as shown). Figure 15 (As shown).

[0049] When the wind turbine 11 is driven by wind force of a preset or higher value, the wind-driven starting gear set 12 rotates to drive the transmission gear set 30 (e.g., Figure 18 As shown), the flywheel 41 drives the flywheel 41 to rotate for a period of time and maintain a constant speed (as shown). Figure 15 (As shown).

[0050] When the wind force received by the wind turbine 11 is lower than or higher than the preset wind force value, the rack unit 22 on the speed control motor 21 is driven by electricity, causing the speed control gear set 26 to be driven by the first one-way gear 28, and the transmission gear set 30 to be driven by the second one-way gear 53, causing the transmission gear set 30 to rotate for a period of time (e.g. Figure 15 As shown), this allows the flywheel 41 to drive the flywheel gear set 42, the generator main shaft gear 43, and the generator main shaft 44 to rotate for a period of time and maintain a constant speed during periods of insufficient wind (e.g., Figure 15 (As shown).

[0051] Please refer to Figure 3As shown, the clutch switch 227 and the lower clutch switch 228 are further electrically connected to a control unit 70 via a wire 60; when the upper starter 2251 triggers the upper clutch switch 227, the control unit 70 further stops the speed control motor 21 from supplying power to the clutch 221 (e.g., Figure 7 As shown); wherein, when the lower start-up unit 2252 triggers the lower clutch switch 228, the control unit 70 further supplies power from the speed control motor 21 to the clutch 221 (as shown).

Figure 14 (As shown).

[0059] As described above, when the wind turbine 11 is driven by a wind force of a preset or higher value, the gear 12f of the wind-driven starting gear set 12 rotates to drive the gear 30a of the transmission gear set 30 (e.g., ...). Figure 11 and Figure 18 As shown), this allows the gear 30g in the transmission gear set 30 to drive the gear 42a and the flywheel 41 in the flywheel gear set 42, and the flywheel 41 then drives the gear 42b to drive the generator main shaft gear 43 and the generator main shaft 44 to rotate for a period of time (e.g. Figure 15As shown); wherein, when the wind force received by the wind turbine 11 is lower than or higher than the preset wind force value, the rack unit 22 on the speed control motor 21 is driven by electricity, causing the gear 26a of the speed control gear set 26 to be driven by the first one-way gear 28, and the gear 30a of the transmission gear set 30 to be driven by the second one-way gear 53, causing the transmission gear set 30 to rotate for a period of time (e.g. Figure 15 As shown), the gear 30g in the transmission gear set 30 can then drive the gear 42a and the flywheel 41 of the flywheel gear set 42, so that the flywheel 41 can drive the flywheel gear set 42, the generator main shaft gear 43, and the generator main shaft 44 to rotate for a period of time and maintain a constant speed during a period of insufficient wind (as shown). Figure 15 (As shown).

[0060] Please refer to Figure 1 As shown, the speed control motor 21 of the first speed control unit 20 is further electrically connected to the generator 45 via a wire 60. The speed control device 1 further includes a control unit 70, which is located between the speed control motor 21 and the generator 45; wherein the control unit 70 is used to enable the generator 45 to provide power to the speed control motor 21 to drive the speed control motor 21 when the wind force received by the wind turbine 11 is lower than the preset or higher wind force value.

[0061] When in use, the rack unit 22 reduces noise generated during operation because the first rocker arm 23 is pushed downwards by the rack 225, rather than by a rotating or pushing structure. Furthermore, using the rack 225 to push the first rocker arm 23 downwards avoids the problem of insufficient force to push the rocker arm when a rotating or pushing structure is used.

[0062] In summary, wind power generation suffers from problems such as the presence or absence of wind, unstable wind force or direction, which can cause the flywheel in the power supply mechanism to gradually slow down or even stop rotating. In order to solve the above-mentioned shortcomings of the existing power supply mechanism, when the wind force received by the wind turbine 11 of this utility model is lower than or higher than the preset wind force value, the rack unit 22 on the speed control motor 21 is driven by electricity, which causes the speed control gear set 26 to be driven by the first one-way gear 28 and the transmission gear set 30 to be driven by the second one-way gear 53, so that the transmission gear set 30 rotates for a period of time. This allows the flywheel 41 to drive the flywheel gear set 42, the generator main shaft gear 43, and the generator main shaft 44 to rotate for a period of time and maintain a constant speed during a period of insufficient wind force.

[0063] The above description is only a preferred embodiment of the present utility model and is illustrative only, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalent alterations can be made to the present utility model within the spirit and scope defined therein, but all of these will fall within the protection scope of the present utility model.
