Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and in particular to a wind-solar-assisted wind power generation device. Background Technology

[0002] A wind-solar-assisted wind power generation system refers to a power generation system that combines wind and solar energy (i.e., a "wind-solar hybrid power generation system"). It combines the advantages of wind power generation and photovoltaic power generation, and improves the stability and reliability of power supply through the synergistic effect of the two renewable energy sources.

[0003] For example, Chinese invention patent CN120520738B discloses a wind-solar-assisted wind power generation device, which belongs to the field of wind power generation technology. This device provides additional power for the rotation of the fan blades at low wind speeds by setting an assist motor, ensuring stable power generation even at low wind speeds. At high wind speeds, the fan blades are driven, and at low wind speeds, the assist ring provides supplementary energy. The inflation adjustment of the annular airbag can temporarily fill the wear gap, so that the power transmission efficiency between the rubber ring and the friction ring can be maintained, ensuring that the power of the assist ring is stably transmitted to the generator at low wind speeds, achieving an emergency effect of short-term operation without immediate maintenance. In existing wind-solar-assisted wind power generation devices, gear speed increasers are often used to amplify the speed of the fan blades in order to increase the speed of the generator rotor. The gear speed increaser is connected by multiple sets of meshing gears to amplify the speed of the fan blades step by step. However, in actual operation, due to the meshing between multiple sets of gears, the fan blades need to overcome a large motion resistance when starting. Therefore, a large wind force is required to drive the fan blades to rotate. As a result, at low wind speeds, the assist motor needs to be started frequently to assist the fan blades to rotate. The frequent start and stop of the assist motor not only shortens the service life of the assist motor, but also causes additional damage to the power supply, thereby increasing the power generation cost of the power generation device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

This effectively reduces the resistance to the generator rotor's starting rotation, allowing the fan blades to rotate at a certain speed even when the wind is weak, thereby driving the generator to continuously generate electricity. This effectively improves the speed-increasing effect. At the same time, compared to the traditional gearbox, the speed-increasing structure achieves better speed-increasing effect with a simpler structure, which can reduce the operating cost of the generator and the difficulty of subsequent maintenance and repair to a certain extent, thereby effectively improving the economic benefits of the wind power generation device. 2. This solution, by setting up a compensation component and adjusting the tension of the first and second ring belts, helps to reduce the risk of slippage during the operation of the first and second ring belts, thereby effectively improving the stability of power transmission between the speed-increasing pulley and the drive wheel, and thus effectively improving the reliability of the power generation device during operation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 16 The present invention provides a technical solution: A wind-solar-assisted wind power generation device includes a support plate 19 for mounting a generator 17. A fixing frame 24 is fixedly connected to the upper outer surface of the support plate 19. A top plate 45 is fixedly connected to the upper side of the fixing frame 24. A movable rod 20 is provided on the upper side of the top plate 45. A rotating component is provided on the outer side of the movable rod 20. A guide rod 39 is fixedly connected to the upper side of the top plate 45. An speed-increasing component is provided on the lower side of the guide rod 39. The speed-increasing assembly includes a speed-increasing wheel 15 and a transmission shaft 37. A drive wheel 36 is fixedly connected to the upper side of the transmission shaft 37. An annular belt 54 is provided between the drive wheel 36 and the speed-increasing wheel 15. A transmission wheel 26 is fixedly connected to the lower side of the transmission shaft 37. A transmission shaft 23 is fixedly connected to the upper side of the generator rotor 17. A transmission wheel 25 is fixedly connected to the upper side of the transmission shaft 23. A transmission belt 27 is rotatably connected between the transmission wheel 25 and the transmission wheel 26. A support assembly is provided on the outer side of the transmission shaft 37.

[0021] In this application, the main body of the rotating component adopts a horizontal axis propeller type. The rotating component includes a fixed sleeve 46 fixedly connected to the upper outer surface of the top plate 45. A bearing 47 is provided on the inner surface of the fixed sleeve 46. The fixed sleeve 46 is rotatably connected to the movable rod 20 through the bearing 47. A limit plate 48 is fixedly connected to the outer surface of the movable rod 20. A mounting sleeve 38 is fixedly connected to the upper outer surface of the limit plate 48. A swing rod 29 is fixedly connected to the inner side of the mounting sleeve 38. A mounting sleeve 30 is fixedly connected to the side of the swing rod 29 away from the mounting sleeve 38. An adjusting component is provided on the outer side of the mounting sleeve 30. A fan blade 14 is connected to the mounting sleeve 30 through the adjusting component.

[0022] By adopting the above technical solution, the working principle of the wind-solar-assisted wind power generation device is that the low-speed rotating blades are connected to the gearbox via the main shaft. The gearbox increases the speed to the high-speed range required by the generator 17, thereby causing the rotor of the generator 17 to rotate at high speed and generate current. The current is then transmitted to the power grid through power equipment such as converters, inverters, and transformers. When the wind-solar-assisted wind power generation device is working, the fan blades 14 are driven by the wind force in the air, which drives the mounting sleeve 30 and the swing rod 29 to rotate through the adjusting component. The top plate 45 supports the fixed sleeve 46, and the fixed sleeve 46 supports the movable rod 20 through the bearing 47. This allows the swing rod 29 to drive the limit plate 48 and the movable rod 20 to rotate smoothly through the mounting sleeve 38. During the rotation of the moving rod 29, it drives the speed-increasing wheel 15 to rotate. The top plate 45 supports the speed-increasing component through the guide rod 39, thereby stabilizing the positions of the transmission shaft 37 and the drive wheel 36. The drive wheel 36 and the speed-increasing wheel 15 are connected by an annular belt 54 for power transmission. During the rotation of the speed-increasing wheel 15, it drives the drive wheel 36 to rotate under the transmission action of the annular belt 54. The drive wheel 36 drives the transmission wheel 26 through the transmission shaft 37, so that the speeds of the drive wheel 36 and the transmission wheel 26 are kept consistent. The transmission wheel 26 drives the transmission wheel 25 to rotate through the transmission belt 27. The transmission wheel 25 drives the generator 17 to rotate at high speed through the transmission shaft 23, thereby enabling the generator 17 to continuously output power. The output current is generated by a speed-increasing wheel 15, whose inner circumference is tens of times greater than that of the drive wheel 36. This allows the speed of the drive wheel 36 to be amplified proportionally to the circumference of the two wheels. When the fan blade 14 drives the speed-increasing wheel 15 to rotate, the transmission between the speed-increasing wheel 15 and the drive wheel 36 effectively increases the speed. Simultaneously, the diameter of the transmission wheel 25 is smaller than that of the transmission wheel 26. The transmission structure between the transmission wheel 25, the transmission wheel 26, and the transmission belt 27 further increases the speed, effectively improving the rotor speed of the generator 17 and thus enhancing power generation efficiency. By incorporating a speed-increasing component, compared to traditional gear speed-increasing structures, it is not necessary to overcome the meshing resistance between the gears in the gearbox, effectively reducing the rotor speed of the generator 17. The resistance to starting rotation allows the fan blades 14 to continue rotating at a certain speed even when the wind is weak, thus driving the generator 17 to continuously generate electricity. This effectively improves the speed increase and power generation efficiency, while reducing the number of start-stop cycles of the generator's auxiliary structure, helping to extend its service life. Furthermore, when wind speed fluctuates at high altitudes, the speed increase wheel 15, due to its inertia and low rotational resistance, can continue rotating for a period of time to generate electricity even when the wind weakens or stops. This avoids frequent start-stop cycles of the generator 17, improving its stability and reliability during operation, and further enhancing the stability of current transmission.Meanwhile, compared to traditional gearboxes, the speed-increasing structure achieves better speed-increasing performance with a simpler structure. This can reduce the manufacturing cost and subsequent maintenance difficulty of the power generation unit to a certain extent, thereby effectively improving the economic efficiency of wind power generation units. By reducing the weight of the speed-increasing components, the difficulty of hoisting and installing the power generation unit can be further reduced, thus helping to lower the construction cost of wind power generation units.

[0023] Specifically, such as Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, there are two sets of limiting plates 48, which are symmetrically distributed, thus effectively improving the support stability of the fan blade 14. The number of swing rods 29 and fan blades 14 are several sets, which are distributed in a ring array. The fan blades 14 can continuously provide power for the rotation of the speed-increasing wheel 15. The outer surface of the fixing frame 24 is hollow, which not only facilitates the installation of the transmission belt 27, but also reduces the overall weight of the equipment.

[0024] like Figure 6 and Figure 8 As shown, the adjusting component includes an adjusting rod 34 fixedly connected to the mounting sleeve 30. An ear plate 32 is rotatably connected to the outer surface of the adjusting rod 34. A connecting plate 31 is fixedly connected to the outer surface of the ear plate 32. A fan blade 14 is fixedly connected to the outer surface of the connecting plate 31. The mounting sleeve 30 is fixedly connected to the upper outer surface of the speed-increasing wheel 15. An adjusting groove 35 is provided through the outer surface of the ear plate 32. A locking rod 33 is threadedly connected to the inner side of the adjusting groove 35.

[0025] By adopting the above technical solution, during the installation of the wind power generation device, the installation angle of the fan blade 14 needs to be adjusted according to the wind force, wind direction and other climate conditions in the area where the power generation device is located, so that the fan blade 14 can be subjected to greater wind force. For this purpose, an adjustment component is set up. The ear plate 32 is fixedly installed on the fan blade 14 through the connecting plate 31. The ear plate 32 can rotate with the adjustment rod 34 as the fulcrum, so that the angle of the ear plate 32 and the fan blade 14 can be flexibly adjusted. When adjusting the angle of the fan blade 14, the operator first loosens the locking rod 33 so that the locking rod 33 is disengaged from the mounting sleeve 30. Then the operator rotates the ear plate 32, and the ear plate 32 drives the fan blade 14 to move through the connecting plate 31, so that the included angle between the fan blade 14 and the mounting sleeve can be adjusted so that the fan blade 14 can achieve a better wind-facing effect. Then the locking rod 33 is tightened again, and the ear plate 32 and the mounting sleeve 38 are locked and limited by the locking rod 33, so that the angle of the fan blade 14 remains stable.

[0026] Specifically, such as Figure 6 and Figure 10As shown, the support assembly includes a movable frame 41 that is slidably connected to the outer surface of the guide rod 39. The guide rod 39 is fixedly connected to the outer surface of the movable frame 41. A support tube 28 is fixedly connected to the outer surface of the guide rod 39. A bearing 40 is fixedly connected to the inner surface of the support tube 28. The support tube 28 is rotatably connected to the transmission shaft 37 through the bearing 40. A compensation assembly is provided on the outer side of the movable frame 41.

[0027] The compensation assembly includes a baffle 42 fixedly connected to the inner surface of the guide rod 39, a screw 44 slidably connected to the outer surface of the baffle 42, a movable frame 41 fixedly connected to the screw 44 on its outer surface, a spring 43 sleeved on the outer side of the screw 44, and an adjusting nut 52 threadedly connected to the outer surface of the screw 44.

[0028] By adopting the above technical solution, when the wind power generation device is working, the movable frame 41 on the outside of the guide rod 39 is used to support the support pipe 28. The support pipe 28 supports the rotation of the transmission shaft 37 through the bearing 47, so that the transmission shaft 37 drives the drive wheel 36 and the transmission wheel 26 to rotate smoothly. In order to maintain the tension of the first ring belt 53 and the second ring belt 54 within an appropriate range and avoid the probability of slippage between the first ring belt 53, the second ring belt 54 and the first speed-increasing wheel 15 and the second speed-increasing wheel 56, a compensation component is set. The guide rod 39 supports the spring 43 through the baffle 42. The spring 43 is sleeved on the outside of the screw 44. When the tension of the first ring belt 53 and the second ring belt 54 fluctuates due to long-term operation, the operator can adjust the tension of the first ring belt 53 and the second ring belt 54 by rotating the adjusting nut 52. The adjusting nut 52 is threadedly connected to the screw 44. The rotation of 2 can adjust the distance between the movable frame 41 and the baffle 42, thereby driving the drive wheel 36 to move synchronously through the movable frame 41. This, in turn, can adjust the distance between the speed-increasing wheel 15 and the drive wheel 36, thus maintaining the tension of the annular belt 24 within an appropriate range. This effectively reduces the probability of slippage between the annular belt 24 and the drive wheel 36, further improving the functionality and stability of the power generation device, and effectively enhancing the stability of power transmission through the annular belt 25. This also effectively improves the reliability of the power generation device during operation. During the movement of the transmission shaft 27, it will drive the transmission wheel 26 to move synchronously, thereby maintaining the tension of the transmission belt 27 within an appropriate range. This prevents the transmission belt 27 from becoming too loose and slipping between the transmission wheel 15 and the transmission wheel 26, thus further improving the continuity of power transmission.

[0029] Specifically, such as Figure 6 and Figure 11As shown, there are two sets of movable frames 41 and baffles 42, which are symmetrically distributed. A power assist assembly is provided on the side of the guide rod 39 away from the drive wheel 36. The power assist assembly includes a power assist motor 51 fixedly connected to the right movable frame 41. A power assist rod 49 is fixedly connected to the upper end of the output shaft of the power assist motor 51. The power assist rod 49 extends through the upper side of the movable frame 41. A second speed-increasing wheel 56 is fixedly connected to the upper side of the swing rod 29. A magnetic sleeve 55 is fixedly connected to the upper end of the power assist rod 49. A power assist wheel 50 is magnetically attracted to the outer surface of the magnetic sleeve 55. An annular belt 53 is provided between the power assist wheel 50 and the first speed-increasing wheel 15.

[0030] Grooves are provided on the outer surfaces of speed-increasing wheel 15, speed-increasing wheel 2 56, drive wheel 36 and assist wheel 50. The diameter of speed-increasing wheel 15 is larger than that of speed-increasing wheel 2 56. Annular belt 2 54 is located outside of annular belt 1 53.

[0031] By adopting the above technical solution, an assist component is provided on the other side of the guide rod 39. The assist component supports the assist motor 51 through the movable frame 41, thereby keeping the position of the assist motor 51 stable. The assist rod 49 is magnetically fixed to the assist wheel 50 through the magnetic sleeve 55. When the wind force is too small to drive the fan blade 14 and the second speed-increasing wheel 56 to rotate, the control system of the wind power generation device controls the assist motor 51 to start moving. At the same time, the magnetic sleeve 55 is made conductive. The assist wheel 50 is magnetically fixed to the assist rod 49 through the magnetic sleeve 55. The output shaft of the assist motor 51 drives the assist wheel 50 to rotate through the assist rod 49 and the magnetic sleeve 55. The annular belt 53 is sleeved in the groove on the surface of the assist wheel 50 and the second speed-increasing wheel 56. The groove can limit the movement of the annular belt 53. The assist wheel 50 drives the second speed-increasing wheel 56 to rotate through the annular belt 53. During the movement of the second speed-increasing wheel 56, it will swing through the swing rod. 29 drives the speed-increasing wheel 15 to rotate, thus providing assistance for the rotation of the speed-increasing wheel 15, enabling the speed-increasing wheel 15 to rotate continuously at a certain speed, thereby ensuring the stability of power output. When the screw 44 drives the movable frame 41 to move, the movable frame 41 will drive the assist wheel 50 to move synchronously, thereby adjusting the tension of the annular belt 53 between the assist wheel 50 and the speed-increasing wheel 2 56, thereby improving the smoothness of the assist component during operation. When the assist component is not working, the magnetic sleeve 55 remains de-energized. At this time, the magnetic force of the magnetic sleeve 55 disappears, and the assist rod 49 can support the rotation of the assist wheel 50 through the magnetic sleeve 55. When the swing rod 29 drives the speed-increasing wheel 2 56 to rotate, the assist wheel 50 can rotate outside the magnetic sleeve 55, thereby preventing the assist wheel 50 from driving the output shaft of the assist motor 51 to rotate, thus keeping the assist motor 51 at a certain temperature.

[0032] Specifically, such as Figure 1As shown, an mounting bracket 22 is fixedly connected to the outer surface of the upper swing rod 29, and a photovoltaic panel 21 is fixedly connected to the outer surface of the mounting bracket 22. The outer surface of the photovoltaic panel 21 is conical, and the mounting bracket 22 is annular. A column 11 is fixedly connected to the lower outer surface of the support plate 19, and an energy storage control module 16 is fixedly connected to the inner surface of the column 11. A lifting frame 12 is provided on the outer side of the column 11, and a lamp body 13 is provided on the upper side of the outer surface of the column 11. A fixing cover 18 is fixedly connected between the support plate 19 and the fixing bracket 24, and the inner surface of the fixing cover 18 is fixedly connected to the generator 17.

[0033] By adopting the above technical solution, the column 11 is used to support the power generation device. The booster wheel 50, drive wheel 36, and speed-increasing wheel 15 are all made of wear-resistant materials, which can extend the service life of the speed-increasing wheel 15, booster wheel 50, and drive wheel 36 to a certain extent. The lifting frame 12 on the outside of the main body can reduce the difficulty of maintenance of the power generation device to a certain extent, and at the same time reduce the cost of using a high-altitude suspended platform for maintenance. The energy storage control module 16 inside the column 11 can store some electrical energy, which ensures the normal operation of the lamp body 13 and the booster motor 51. The swing rod 29 is fixedly installed on the flexible photovoltaic panel 21 through the mounting bracket 22. Under the action of sunlight, the photovoltaic panel 21 can continuously generate electricity. In the absence of wind... When the fan blade 14 cannot rotate by wind power, the electrical energy generated by the photovoltaic panel 21 can ensure the stable operation of the booster motor 51, thereby ensuring the continuous operation of the power generation device. The flexible photovoltaic panel 21 is conical and set on the upper side of the speed-increasing component, which can guide rainwater and protect the components such as the generator 17 below from rain. At the same time, the photovoltaic panel 21 can rotate with the swing arm 29, which can reduce the adhesion of dust on the surface of the photovoltaic panel 21, thereby ensuring the power generation efficiency of the photovoltaic panel 21 and extending the service life of the above components to a certain extent. In addition, compared with the traditional gearbox, the speed-increasing component can effectively reduce the weight of the equipment, thereby reducing the load on the column 11 to a certain extent.

When the generator speed is 240 rpm, the output voltage is 337.5V, the output current is 27.50A, the output power is 16075.13W, the input power is 18514.30W, the output efficiency is 91.78%, and the input torque is 696.92Nm. When the generator speed is 240 rpm (design standard speed), the output voltage is 400V, the output current is 32.66A, the output power is 22626.85W, the input power is 24632.00W, the output efficiency is 91.86%, and the input torque is 784.12Nm. Working Principle: When the wind power generation device is working, the fan blade 14 is driven by the wind force in the air, which drives the mounting sleeve 30 and the swing rod 29 to rotate through the adjusting component. The mounting sleeve 38 drives the limiting plate 48 and the movable rod 20 to rotate smoothly. During the rotation of the swing rod 29, it drives the speed-increasing wheel 15 to rotate. During the rotation of the speed-increasing wheel 15, it drives the drive wheel 36 to rotate under the transmission action of the annular belt 54. The drive wheel 26 drives the drive wheel 25 to rotate through the transmission belt 27. The drive wheel 25 drives the generator 17 to rotate at high speed through the transmission shaft 23, so that the generator 17 can continuously output current. The ear plate 32 drives the fan blade 14 to move through the connecting plate 31, so as to adjust the angle between the fan blade 14 and the mounting sleeve, so that the fan blade 14 can achieve a better wind-facing effect. The output shaft of the assist motor 51 drives the assist wheel 50 to rotate through the assist rod 49 and the magnetic sleeve 55. The assist wheel 50 and the... The annular belt 53 drives the speed-increasing wheel 56 to rotate. During the movement of the speed-increasing wheel 56, the swing rod 29 drives the speed-increasing wheel 15 to rotate, thus providing assistance for the rotation of the speed-increasing wheel 15. This allows the speed-increasing wheel 15 to rotate continuously at a certain speed, thereby ensuring the stability of the power output. As the adjusting nut 52 rotates, the distance between the movable frame 41 and the baffle 42 can be adjusted, which in turn can adjust the distance between the speed-increasing wheel 15 and the drive wheel 36. This allows the tension of the annular belt 54 to be maintained within an appropriate range, reducing the probability of slippage between the annular belt 54 and the drive wheel 36. The swing rod 29 fixes the flexible photovoltaic panel 21 to the mounting frame 22. Under the action of sunlight, the photovoltaic panel 21 can continuously generate electricity. When the fan blade 14 cannot rotate by wind power in the absence of wind, the electrical energy generated by the photovoltaic panel 21 can ensure the stable operation of the power-assist motor 51.
