Description

Technical Field

[0001] This invention relates to the field of wind power energy technology, and in particular to a wind power generation device and its operation method. Background Technology

[0002] Traditional ships rely solely on sails to propel themselves when using wind power. However, sails are only used when the wind is light, either with or against the wind. When the wind is strong against the wind, the sails need to be furled and the anchor dropped to reduce the wind's impact on the ship's course, thus failing to fully utilize the wind's energy. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art and to provide a wind power generation device.

[0004] This invention also provides an operation method for the above-described wind power generation device.

[0005] According to a first aspect of the present invention, a wind power generation device is provided, comprising: a wind cup, a central unit, a second rotating shaft, a generator set, and a second transmission assembly. The wind cup includes a fixed-axis wind cup and a rotating wind cup. The central unit includes a drive assembly and a first transmission assembly. The drive assembly includes a power component. The first transmission assembly includes a fixed plate, a first gear, a second gear, a worm shaft, a worm wheel, and a first rotating shaft. The output shaft of the power component passes through the fixed plate and rotates synchronously with the first gear. The first gear meshes with the second gear, and the second gear drives the worm shaft to rotate. The worm shaft meshes with the worm wheel, and the worm wheel rotates synchronously with the first rotating shaft. The first rotating shaft and the rotating wind cup move synchronously. The torque of the rotating wind cup and the fixed-axis wind cup is transmitted to the second rotating shaft. The second rotating shaft and the generator set are connected via the second transmission assembly.

[0006] Beneficial effects: This wind power generation device includes wind cups, a central unit, a second rotating shaft, a generator set, and a second transmission assembly. The wind cups include a fixed-axis wind cup and a rotating wind cup. The central unit includes a drive assembly and a first transmission assembly. The drive assembly includes a power component. The first transmission assembly includes a fixed plate, a first gear, a second gear, a worm shaft, a worm wheel, and a first rotating shaft. The output shaft of the power component passes through the fixed plate and rotates synchronously with the first gear. The first gear meshes with the second gear, which drives the worm shaft to rotate. The worm shaft meshes with the worm wheel, which rotates synchronously with the first rotating shaft. The first rotating shaft and the rotating wind cup move synchronously. The torque of the rotating wind cup and the fixed-axis wind cup is transmitted to the second rotating shaft. The second rotating shaft and the generator set are connected through the second transmission assembly. When a ship is in a headwind, the fixed-axis wind cup and the rotating wind cup generate a torque under the action of the wind and are driven, transmitting the rotation to the generator set. The rotor winding of the generator set generates a changing magnetic field under the action of the excitation current and its own rotation, which causes the stator winding to generate an induced AC electromotive force. The output AC induced electromotive force is processed by the frequency converter circuit and directly connected to the ship's power system or stored in the energy storage device, making full use of the wind energy when the ship is in a headwind.

[0007] According to one embodiment of the wind power generation device of the present invention, the first transmission component further includes a sleeve, a first bearing and a second bearing, the sleeve, the first bearing and the second bearing are all sleeved on the first rotating shaft, and the sleeve is located between the first bearing and the second bearing, and the first bearing is embedded in the fixed plate.

[0008] According to one embodiment of the wind power generation device of the present invention, the second transmission component includes a third gear and a fourth gear, the second rotating shaft and the third gear rotate synchronously, the fourth gear rotates synchronously with the power output shaft of the generator set, and the fourth gear meshes with the third gear.

[0009] According to one embodiment of the wind power generation device of the present invention, the central unit includes a housing, and when the fixed-axis wind cup and the rotating wind cup rotate, the housing drives the second rotating shaft to rotate, thereby enabling the generator set to operate.

[0010] According to one embodiment of the wind power generation device of the present invention, the second rotating shaft is further connected to a third bearing and a central base, and the third gear, the third bearing and the central base are sequentially sleeved along the direction of rotation output of the second rotating shaft.

[0011] According to another embodiment of the present invention, an operating method is provided, employing the wind power generation device described in any of the above claims, wherein the drive assembly further includes a power component control unit, the power component control unit including a microcontroller, a driver, a counter, and a timer:

[0012] When there is a tailwind:

[0013] When the microcontroller receives the rotation signal, the counter starts counting, the timer starts timing, and after the timer finishes timing, it enters the interrupt service routine. The microcontroller sends out pulse data, which is decoded by the driver and then output to the power component. The power component rotates by an angle and repeatedly outputs the pulse data until the counter finishes counting. Then, the microcontroller enters standby mode, and the power component also enters standby mode.

[0014] When the rotating wind cup and the fixed-axis wind cup are facing the same direction, the rotating wind cup rotates half a turn. The rotating wind cup is subjected to wind force F1, and the fixed-axis wind cup is subjected to wind force F0. At this time, the torque of the fixed-axis wind cup acting on the central unit is M0 = F0·L / 2, and the torque of the rotating wind cup acting on the central unit is M1 = F1·L / 2. Since the rotating wind cup and the fixed-axis wind cup have the same shape, F0 = F1 and M0 = M1. The rotating wind cup and the fixed-axis wind cup do not rotate, but are only subjected to the resultant force F in the forward direction.

[0015] When the rotating wind cup and the fixed-axis wind cup face opposite directions, the power component rotates under the control of the power component control unit. The power component drives the first transmission assembly, causing the rotating wind cup to complete half a rotation. After the rotating wind cup rotates, the force-bearing surfaces of the rotating wind cup and the fixed-axis wind cup change, causing the wind force received by the rotating wind cup and the fixed-axis wind cup to be different and thus rotate.

[0016] When facing headwinds:

[0017] When the microcontroller receives the rotation signal, in the same step S0, the power component rotates and the rotating wind cup rotates half a turn.

[0018] When the rotating wind cup and the fixed-axis wind cup face opposite directions, the wind force acting on the rotating wind cup and the fixed-axis wind cup is different. The force on the concave surface of the rotating wind cup is greater than the force on the convex surface of the fixed-axis wind cup. At this time, the torques acting on the central unit by the rotating wind cup and the fixed-axis wind cup are different. The two ends of the second rotating shaft lose balance and rotate.

[0019] The torque of the rotating and fixed-axis wind cups is transmitted to the generator set through the second transmission component, ultimately generating an induced electromotive force.

[0020] Beneficial effects: This invention fully utilizes wind energy. By rotating the wind cups and the fixed-axis wind cups, the vessel can adapt to different wind directions and utilize wind energy. Especially in headwinds, wind energy can be effectively converted into electrical energy through a generator, which then powers the vessel's electrical system. This invention can significantly reduce the consumption of other fossil fuels by the vessel, ensuring its sustainable operation and reducing the cost of voyages.

[0021] According to another embodiment of the present invention, the wind power generation device further includes a light-emitting diode, the microcontroller is connected to the driver, and when the microcontroller receives a rotation signal, it controls the driver to drive the power component to rotate, and the light-emitting diode can display different operating states of the power component.

[0022] According to another embodiment of the present invention, the ratio of the rotational speed n1 of the power component to the rotational speed n3 of the rotating wind cup is a self-locking reduction transmission ratio i13, the transmission ratio of the first gear and the second gear is i12, the transmission ratio of the worm gear and the worm shaft is i23, and the relationship between each transmission ratio is: i13=i12·i23.

[0023] According to another embodiment of the present invention, in the operation method, the opening direction of the rotating wind cup and the fixed-axis wind cup needs to be manually adjusted, and the central unit is provided with an external control interface to complete the accuracy calibration through external control.

[0024] According to another embodiment of the present invention, the wind power generation device uses a converter connected in parallel with the output terminal of the power component through a reactor to adjust the reactive power required for excitation of the power component, and the active power of the power component is directly output to the AC load, thereby realizing the output of the power component.

[0031] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, top surface, bottom, inner side, outer side, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0034] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0035] Currently, anemometers are widely used wind sensors for wind monitoring in scenarios such as ships, ports, and meteorological monitoring points. However, anemometers do not provide any power to ships during operation. Therefore, it is necessary to use wind power to drive ships or generate energy through wind power generation. This can reduce the consumption of fossil fuels during ship operation to some extent, mitigate the environmental problems caused by fossil fuel emissions, and also save significant costs and improve economic efficiency. Wind power generation, as a relatively mature technology, has been widely applied, but its application on ships is currently limited. The main reason is that it requires the design of entirely new structures to obtain an optimal energy supply solution for ship operation.

[0036] To address the issue of wind power supply for ship operation, this invention presents a novel wind power generation device. By altering the relative structure of each blade, the function of a sail is integrated with wind power generation.

[0037] Traditional ships rely solely on sails for propulsion when using wind power. However, sails are only used when the wind is light, either with or against the wind. In strong headwinds, sails must be furled and anchor dropped to minimize the wind's impact on the ship's course. To fully utilize wind energy in headwinds, it's necessary to convert it into electricity or other forms of energy for storage. Therefore, designing a device that can power ships in all wind directions is essential to address these issues.

[0038] Reference Figures 1 to 5 A wind power generation device includes a wind cup, a central unit, a second rotating shaft 231, a generator set 250, and a second transmission assembly. The wind cup includes a fixed-axis wind cup 110 and a rotating wind cup 120. The central unit includes a drive assembly and a first transmission assembly. The drive assembly includes a power component 211 and a power component control unit 212. The power component 211 is a stepper motor, and the power component control unit 212 is a stepper motor control module. The first transmission assembly includes a fixed plate 221, a first gear 222, a second gear 223, a worm shaft 224, a worm wheel 225, and a first rotating shaft 226. The output shaft of the stepper motor passes through the fixed plate 221 and rotates synchronously with the first gear 222. The first gear 222 meshes with the second gear 223 to redirect the torque. The second gear 223 drives the worm shaft 224 to rotate. The worm shaft 224 meshes with the worm wheel 225. The worm wheel 225 rotates synchronously with the first rotating shaft 226. The first rotating shaft 226 and the rotating fan cup 120 move synchronously. The torque of the rotating fan cup 120 and the fixed-axis fan cup 110 is transmitted to the second rotating shaft 231.

[0039] It is easy to understand that the second shaft 231 and the generator set 250 are connected via the second transmission assembly.

[0040] In one specific embodiment, the second transmission assembly includes a third gear 232 and a fourth gear 240. The second rotating shaft 231 and the third gear 232 rotate synchronously, and the fourth gear 240 rotates synchronously with the power output shaft of the generator set 250. The fourth gear 240 meshes with the third gear 232.

[0041] Reference Figure 1 and Figure 4 The wind cup is a semi-hollow ellipse, symmetrically distributed on both sides of the second rotating shaft 231, and the fixed-axis wind cup 110 is fixed on the housing 260 of the central unit.

[0042] In one specific embodiment, the first transmission assembly further includes a sleeve 227, a first bearing 228, and a second bearing 229. The sleeve 227, the first bearing 228, and the second bearing 229 are all sleeved on the first rotating shaft 226, with the sleeve 227 located between the first bearing 228 and the second bearing 229. The first bearing 228 is embedded within the fixed plate 221. The first bearing 228 and the second bearing 229 bear the bending moment generated by the gravity of the rotating wind cup.

[0043] In one specific embodiment, when the fixed-axis wind cup 110 and the rotating wind cup 120 rotate, the housing 260 drives the second rotating shaft 231 to rotate, which in turn drives the third gear 232 and the fourth gear 240 to rotate in sequence, thereby making the generator set 250 operate and storing the wind energy of the wind cup in the form of electrical energy.

[0044] In one specific embodiment, the second rotating shaft 231 is also connected to the third bearing 233 and the central base 234, and the third gear 232, the third bearing 233 and the central base 234 are sequentially mounted along the direction of rotation output of the second rotating shaft 231.

[0045] In one specific embodiment, an operation method for a wind power generation device according to an embodiment of the present invention is provided. In any of the above embodiments of the wind power generation device, the stepper motor control module includes a microcontroller, a driver, a counter, and a timer.

[0046] When the ship is with the wind:

[0047] S0: When the microcontroller receives the rotation signal, the counter starts counting and the timer starts counting. After the timer finishes counting, the interrupt service routine is entered. The microcontroller sends pulse data, which is decoded by the driver and then output to the stepper motor. The stepper motor rotates an angle and repeatedly outputs pulse data until the counter finishes counting. The microcontroller then enters standby mode, and the stepper motor enters standby mode as well.

[0048] S2: When the rotating wind cup 120 and the fixed-axis wind cup 110 are facing the same direction, the rotating wind cup 120 rotates half a turn. The rotating wind cup 120 is subjected to wind force F1, and the fixed-axis wind cup 110 is subjected to wind force F0. At this time, the torque of the fixed-axis wind cup 110 acting on the central unit is M0 = F0·L / 2, and the torque of the rotating wind cup 120 acting on the central unit is M1 = F1·L / 2. Since the rotating wind cup 120 and the fixed-axis wind cup 110 have the same shape, F0 = F1 and M0 = M1. The rotating wind cup 120 and the fixed-axis wind cup 110 do not rotate, but are only subjected to the resultant force F in the forward direction.

[0049] S4: When the rotating fan cup 120 and the fixed-axis fan cup 110 face opposite directions, the stepper motor rotates under the control of the stepper motor control module. The stepper motor drives the first transmission component, causing the rotating fan cup 120 to complete half a rotation. After the rotating fan cup 120 rotates, the force-bearing surfaces of the rotating fan cup 120 and the fixed-axis fan cup 110 change, resulting in different wind forces on the rotating fan cup 120 and the fixed-axis fan cup 110, causing them to rotate. The stepper motor outputs torque, which is amplified through the first transmission component, driving the rotating fan cup to rotate 180°, making it centrally or axially symmetrical with the fixed-axis fan cup. The worm gear shaft is self-locking, ensuring that the torque output can only be sent to the fan cup by the stepper motor, preventing the rotating fan cup from transmitting torque to the stepper motor through the first transmission component, thus preventing the fan cup from rotating on its own under the action of wind force.

[0050] When a ship is facing a headwind:

[0051] S6: When the microcontroller receives the rotation signal, the stepper motor rotates, and the fan cup rotates 120 degrees, making it rotate half a turn.

[0052] S8: When the rotating wind cup 120 and the fixed-axis wind cup 110 face opposite directions, the wind forces acting on the rotating wind cup 120 and the fixed-axis wind cup 110 are different. The force on the concave surface of the rotating wind cup 120 is greater than the force on the convex surface of the fixed-axis wind cup 110. At this time, the torques acting on the central unit by the rotating wind cup 120 and the fixed-axis wind cup 110 are different. The two ends of the second rotating shaft 231 lose balance and rotate.

[0053] S10: The diameter of the third gear 232 is larger than that of the fourth gear 240, which amplifies the transmission ratio i. The torque of the rotating wind cup 120 and the fixed-axis wind cup 110 is transmitted to the generator set 250 through the second transmission component, and finally an induced electromotive force is generated.

[0054] The wind power generation device also includes light-emitting diodes (LEDs). A microcontroller is connected to a driver. When the microcontroller receives a rotation signal, it controls the driver to drive the stepper motor to rotate. The LEDs can display different operating states of the stepper motor.

[0055] The ratio of the stepper motor speed n1 to the rotating wind cup 120 speed n3 is the self-locking reduction transmission ratio i13. The transmission ratio of the first gear 222 and the second gear 223 is i12. The transmission ratio of the worm gear 225 and the worm shaft 224 is i23. The relationship between the transmission ratios is: i13=i12·i23.

[0056] In step S0, the timer terminates and sends an interrupt request. The microcontroller responds to the interrupt request and outputs a control signal to the stepper motor control module. The stepper motor control module decodes, modulates, and outputs an analog signal. After receiving the analog signal, the stepper motor rotates by one angle. At this time, the counter increments by 1. The operation is repeated until the counter finishes counting. At this time, the microcontroller completes the control work and the stepper motor stops rotating.

[0057] It is easy to understand that due to mechanical vibration and wear, the control accuracy of the wind power generation device will accumulate errors over a long period of operation, resulting in a decrease in the accuracy of the rotating wind cup. In the operation method, it is necessary to manually adjust the opening direction of the rotating wind cup 120 and the fixed-axis wind cup 110. The central unit is equipped with an external control interface to complete the accuracy calibration through external control.

[0058] In simple terms, a wind power generation device uses a converter connected in parallel with the output of a stepper motor via a reactor to regulate the reactive power required for the stepper motor's excitation. The active power of the stepper motor is directly output to the AC load, thereby realizing the output of the stepper motor.

[0059] In simple terms, the rotation of the second shaft is driven by the force couple generated by the fixed-axis wind cup and the rotating wind cup under the action of wind, and is transmitted to the generator through the meshing of the third and fourth gears. Under the action of the excitation current and its own rotation, the rotor winding of the generator generates a changing magnetic field, which causes the stator winding to generate an induced AC electromotive force. The output AC induced electromotive force is processed by circuits such as frequency converters and then directly connected to the ship's power system or stored by an energy storage device.

[0060] It is easy to understand that the output torque and rotation angle of the stepper motor need to be precisely controlled to ensure that the rotating cup can rotate at a fixed angle. This requires the use of a control chip to output pulses to drive the stepper motor.

[0061] As is easily understood, the speed of a stepper motor is determined by wind power. To achieve the output of the stepper motor, a converter is connected in parallel with the stepper motor output via a reactor to regulate the reactive power required for motor excitation. The active power of the stepper motor is directly output to the AC load. The reactor is a balancing reactor used to limit pulsating current.

[0062] It is readily understood that the synchronous rotation mentioned in the embodiments of this application refers only to direct connection, excluding connection through connecting parts, such as key connection, interference fit, integral molding, threaded connection, etc. Synchronous motion includes both direct connection between components and connection between components through connecting parts. Synchronous motion does not mean that the components move at the same speed or in the same direction.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
