Description

Technical Field

[0002] Traditional bladed wind turbines convert the rotational mechanical energy of blades into electrical energy through electromagnetic induction. They have high requirements for wind speed and are usually placed along the coast, at sea, and in other high-wind areas in order to obtain higher and more stable wind speeds and ultimately convert the kinetic energy of wind into electrical energy. One way to generate power from bladeless wind power is to use an electromagnetic wind vibration energy harvesting device to utilize the vortex-induced vibration generated by the fluid in the natural wind field passing through a circular cross-section bluff body, and then convert the wind energy into mechanical energy through a mechanical vibration structure and an electromagnetic conversion structure, and then convert the mechanical energy into electrical energy.

In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] In the prior art, there has been no research in the art on how to combine bladeless wind power generation with other power generation methods to produce better power generation effects.

[0026] The embodiment of the present invention provides a hybrid power generation system based on bladeless wind power generation and photovoltaic power generation and a control method thereof, which combines bladeless wind power generation and photovoltaic power generation, and can not only obtain electricity generated by the two power generation methods at the same time, but also have a good influence on the bladeless wind generator by adjusting the direction of the photovoltaic panels, so that the effective wind force received by the bladeless wind generator is stronger, thereby enhancing the effect of bladeless wind power generation, so that the effect of one plus one is greater than two.

[0027] Specifically, the embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0028] Example 1 refer to Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a hybrid power generation system based on bladeless wind power generation and photovoltaics, the hybrid power generation system based on bladeless wind power generation and photovoltaics includes a plurality of photovoltaic power generation devices 1 and a plurality of bladeless wind power generation devices 2, the photovoltaic power generation devices 1 and the bladeless wind power generation devices 2 are arranged in a cross array; wherein: the photovoltaic power generation device 1 includes a photovoltaic panel 101 and an angle adjustment component 102, the angle adjustment component 102 is connected to the photovoltaic panel 101 to adjust the photovoltaic panel 101 to be inclined toward the wind direction according to the wind direction. Because the photovoltaic power generation device 1 and the bladeless wind power generation device 2 are arranged in a cross array, after the photovoltaic panel 101 is adjusted to be tilted toward the wind direction, an upward tilted wind channel will be formed on the upper surface of the photovoltaic panel 101, so that the wind will travel along the upper surface of the photovoltaic panel 101, and then concentrate on blowing toward the higher part of the bladeless wind power generation device 2 behind the photovoltaic panel 101, so that the effective wind force received by the bladeless wind power generation device 2 is stronger, thereby enhancing the effect of bladeless wind power generation.

[0029] Specifically, refer to Figure 1As shown, in some embodiments, the photovoltaic power generation device 1 and the bladeless wind power generation device 2 can be arranged in a cross array in such a way that the photovoltaic power generation devices 1 in each row and column are arranged in an array at a certain distance; the bladeless wind power generation device 2 is arranged at the intersection of the gaps between the rows and columns of the photovoltaic power generation device 1, so that the bladeless wind power generation devices 2 in each row and column are arranged in a cross array with the photovoltaic power generation devices 1 in each row and column. This arrangement can maximize the saving of site resources while minimizing the impact between the photovoltaic power generation device 1 and the bladeless wind power generation device 2.

[0030] refer to Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the angle adjustment assembly 102 includes a motor box 1021 and a plurality of pull ropes 1022, wherein the motor box 1021 is provided with a plurality of first rotating motors 1023, and a reel 1024 is provided on the rotating shaft of the first rotating motor 1023, and the reel 1024 is located outside the motor box 1021; one end of the pull rope 1022 is connected to the reel 1024, and the other end of the pull rope 1022 is connected to the photovoltaic panel 101. Specifically, the pull rope 1022 can be set to four, and the first rotating motor 1023 can also be set to four, and each pull rope 1022 corresponds to one first rotating motor 1023; the rotating shaft of each first rotating motor 1023 extends in different directions respectively, so that the four reels 1024 are located on four different sides of the motor box 1021, so as to better connect with different corners of the photovoltaic panel 101 through the pull rope 1022.

[0031] refer to Figure 4 As shown, in some embodiments, a plurality of steering wheels 1025 are arranged outside the motor box 1021, one end of the pull rope 1022 is connected to the drum 1024, and the other end of the pull rope 1022 is connected to the photovoltaic panel 101 after passing through the steering wheel 1025. Specifically, the steering wheel 1025 can be a fixed pulley, which plays a steering role, so that the first rotating motor 1023 can better retract and release the pull rope 1022. When the specific setting position is set, the drum 1024 can be set on the right side of each side of the motor box 1021, and the steering wheels 1025 are also set in four and arranged on the left side of each side of the motor box 1021, so that a pair of the drums 1024 and the steering wheels 1025 adjacent to each other on each side can complete the steering and connection of the pull rope 1022, thereby better retracting and releasing each pull rope 1022.

[0032] refer to Figure 6As shown, in some embodiments, a plurality of mounting rings 1011 are provided on the bottom surface of the photovoltaic panel 101, and a connecting ring 1012 is provided on the mounting ring 1011, and the pull rope 1022 is connected to the connecting ring 1012. Specifically, the mounting ring 1011 and the connecting ring 1012 can be provided at the four corners of the photovoltaic panel 101, corresponding to each of the pull ropes 1022. By rolling up the two pull ropes 1022 on one side and releasing the two pull ropes 1022 on the other side, the inclination angle of the photovoltaic panel 101 can be adjusted. By adjusting the inclination angle of the photovoltaic panel 101, not only can the power generation effect of the bladeless wind power generation device 2 be optimized, but also the inclination direction of the photovoltaic panel 101 can be adjusted to be always facing the direction of sunlight, so as to improve the power generation efficiency of the photovoltaic panel 101 itself.

[0033] refer to Figure 7 and Figure 8 As shown, in some embodiments, a support column 1013 is provided in the middle of the bottom surface of the photovoltaic panel 101, and a first sphere 1014 is provided at the bottom end of the support column 1013; a connecting column 1026 penetrating the motor box 1021 is provided in the middle of the motor box 1021, the motor box 1021 is fixed on the connecting column 1026, and a second sphere 1027 is provided at the top of the connecting column 1026; the second sphere 1027 is hollow and has an opening at the top, the first sphere 1014 is provided in the second sphere 1027, and the outer diameter of the first sphere 1014 is consistent with the inner diameter of the second sphere 1027. In this way, the first sphere 1014 can rotate in the second sphere 1027, and the diameter of the opening at the top of the second sphere 1027 is smaller than the outer diameter of the first sphere 1014, so that the first sphere 1014 will not fall out of the second sphere 1027. Through the above arrangement, during the process of retracting and releasing the pull rope 1022 , the photovoltaic panel 101 is adjusted to deflect and tilt around the first sphere 1014 .

[0034] refer to Figure 7 and Figure 8 As shown, in some embodiments, a plurality of supporting inclined columns 1015 are provided between the supporting column 1013 and the bottom surface of the photovoltaic panel 101. The supporting inclined columns 1015 serve as reinforcing ribs to strengthen the structure.

[0035] refer to Figure 3 , Fig. 9 and Fig.10As shown, in some embodiments, the photovoltaic power generation device 1 further includes a cylinder 103 and a telescopic motor 104 disposed in the cylinder 103, and the output end of the telescopic motor 104 is connected to the angle adjustment component 102. Specifically, the cylinder 103 protects the telescopic motor 104 inside; the output end of the telescopic motor 104 is connected to the bottom end of the connecting column 1026 of the angle adjustment component 102, and then the connecting column 1026 is driven by the output end of the telescopic motor 104, and then the entire angle adjustment component 102 and the photovoltaic panel 101 are driven to rise or fall. By adjusting the height of the photovoltaic panel 101 in this way, the function of the photovoltaic panel 101 can be better exerted. For example, when there is sufficient sunlight, by raising the height of the photovoltaic panel 101, it is not affected by the shadow formed by the bladeless wind power generation device 2. In the case of weak or no sunlight, the height of the photovoltaic panel 101 can be lowered, and the photovoltaic panel 101 can be combined with the function of adjusting the angle according to the wind direction to optimize the power generation effect of the bladeless wind power generation device 2. Generally speaking, there is a support component at the bottom of the bladeless wind power generation device 2 that does not participate in receiving wind sway. When the height of the photovoltaic panel 101 is lowered to this position and tilted, there is no need to worry that the photovoltaic panel 101 will have a negative impact on the power generation efficiency of the bladeless wind power generation device 2. When the photovoltaic panel 101 provides a wind rising channel, it will only have a positive impact on the power generation efficiency of the bladeless wind power generation device 2.

[0036] refer to Fig. 9 As shown, in some embodiments, a fixing plate 106 is provided below the cylinder 103, the diameter of the fixing plate 106 is larger than the diameter of the cylinder 103, and a plurality of mounting holes are provided on the fixing plate 106, and the fixing plate 106 and the cylinder 103 are installed in the site through bolts and the mounting holes. The bottom of the bladeless wind power generation device 2 can also be installed in the site by means of a fixing plate.

[0037] refer to Fig.10 As shown, in some embodiments, a second rotating motor 105 is provided below the telescopic motor 104, and the rotating shaft of the second rotating motor 105 is fixed to the bottom end of the telescopic motor 104. The second rotating motor 105 can drive the telescopic motor 104, the angle adjustment component 102 thereon, and the photovoltaic panel 101 to rotate as a whole, so that the photovoltaic panel 101 can face any wind direction. For example, the original photovoltaic panel 101 can be rotated and adjusted in the east-west direction or in the north-south direction under the drive of the angle adjustment component 102. The schematic diagram after adjustment is shown in FIG. Figure 2 As shown, assuming Figure 2The photovoltaic panel 101 is tilted toward the south, and the wind direction at this time is also due south wind, then the photovoltaic panel 101 has the best wind drainage effect on the wind, and the assistance to the bladeless wind power generation device 2 is the greatest. However, if the wind direction at this time is southeast wind instead of due south wind, then Figure 2 In the state shown, the wind drainage effect of the photovoltaic panel 101 will be reduced. Based on this situation, the rotation angle of the photovoltaic panel 101 is adjusted by the second rotating motor 105 so that its tilt direction faces southeast. Fig.11 As shown, the photovoltaic panel 101 can once again achieve the best wind drainage effect.

[0038] In summary, the embodiment of the present invention combines bladeless wind power generation and photovoltaic power generation, which can not only obtain electricity generated by the two power generation methods at the same time, but also have a good impact on the bladeless wind generator by adjusting the direction of the photovoltaic panel, so that the effective wind force received by the bladeless wind generator is stronger, thereby enhancing the effect of bladeless wind power generation, so that the effect of one plus one is greater than two. Furthermore, the photovoltaic panel itself can also better receive solar energy by adjusting its direction, making the effect of photovoltaic power generation stronger.

[0039] Example 2 On the basis of the above-mentioned embodiment 1, this embodiment describes in detail the control method of the hybrid power generation system based on bladeless wind power generation and photovoltaic power generation.

[0040] refer to Fig.12 As shown, in some embodiments, the control method of the hybrid power generation system based on bladeless wind power generation and photovoltaic power generation includes the following steps.

[0041] Step 101: At regular intervals, determine whether the current time node is in the first time period or the second time period. Specifically, the first time period may be a night time period, such as from 19:00 to 7:00; the second time period may be a day time period, such as from 7:00 to 19:00; the specific division may be set according to the actual situation of different seasons. The current time node may be determined at regular intervals, such as once every one hour, half an hour, or two hours, and the specific interval may be determined according to the needs.

[0042] Step 102: If the current time node is in the first time period, obtain the current wind direction. Specifically, the first time period is the night time period. If it is determined that the current time node is in the night time period, then the photovoltaic panel 101 has extremely low working efficiency or even does not work. In this case, the main purpose is to improve the working efficiency of the bladeless wind power generation device 2, so the current wind direction is obtained to make subsequent adjustments based on the current wind direction. For obtaining the wind direction, it can be obtained directly from the wind direction in the weather forecast, or a wind direction tester can be set up next to the hybrid power generation system based on bladeless wind power generation and photovoltaics to obtain the real-time wind direction. Due to the uncertainty of the weather forecast, it is preferred to obtain the real-time wind direction by setting up a wind direction tester.

[0043] Step 103: Adjust the photovoltaic panel 101 to tilt toward the wind direction. Specifically, if the current wind direction is south wind, adjust the photovoltaic panel 101 to tilt toward the south. Figure 2 As shown, when the south wind blows, the wind at the height of the photovoltaic panel 101 will move upward along the inclined surface of the photovoltaic panel 101, and then merge with the wind above the photovoltaic panel 101, generating stronger wind to act on the bladeless wind power generation device 2, so that the power generation efficiency of the bladeless wind power generation device 2 is improved. Similarly, if the current wind direction is southeast wind, adjust the photovoltaic panel 101 to tilt toward the southeast, refer to Fig.11 shown.

[0044] The main purpose of the above steps is to assist the bladeless wind turbine generator 2 without affecting the power generation effect of the photovoltaic panel 101. Therefore, the above steps are performed during the night time period. The photovoltaic panel 101 hardly works during the night time period. Adjusting its direction will not affect its working efficiency, but will only make the effective wind force received by the bladeless wind turbine generator 2 stronger, thereby improving the working efficiency of the bladeless wind turbine generator 2.

[0045] refer to Fig.13 As shown, in some embodiments, the control method of the hybrid power generation system based on bladeless wind power generation and photovoltaic power generation also includes the following steps.

[0046] Step 201: At regular intervals, determine whether the current time node is in the first time period or the second time period. Specifically, the first time period may be a night time period, such as from 19:00 to 7:00; the second time period may be a day time period, such as from 7:00 to 19:00; the specific division may be set according to the actual situation of different seasons. The current time node may be determined at regular intervals, such as one hour, half an hour, or two hours, and the specific interval may be determined according to the needs.

[0047] Step 202: If the current time node is the second time period, obtain the current sun direction. Specifically, the second time period is the daytime period. If it is determined that the current time node is in the daytime period, then the working efficiency of the photovoltaic panel 101 is relatively high, while the working efficiency of the bladeless wind power generation device 2 is relatively low, because generally speaking, the wind at night is stronger than the wind during the day; in this case, how to ensure the working efficiency of the photovoltaic panel 101 has a higher priority than improving the working efficiency of the bladeless wind power generation device 2 through the photovoltaic panel 101; so the main purpose in this case is to improve the working efficiency of the photovoltaic panel 101, so the current sun direction is obtained to make subsequent adjustments according to the current sun direction. To obtain the direction of the sun, the azimuth of the sun changing over time can be obtained based on the statistics of the local sun's position changing over time in past seasons; or a solar incidence angle tracking meter can be set up next to the hybrid power generation system based on bladeless wind power generation and photovoltaics to obtain the real-time solar incidence angle, that is, the real-time solar azimuth; for accuracy considerations, it is preferred to set up a solar incidence angle tracking meter to obtain the real-time solar azimuth.

[0048] Step 203: Adjust the photovoltaic panel 101 to face the sun. Specifically, if the current sun direction is directly above the photovoltaic panel 101, then adjust the photovoltaic panel 101 to be horizontal to better receive sunlight; if the current sun direction is directly above the photovoltaic panel 101 and offset 30 degrees to the east, then adjust the photovoltaic panel 101 to offset 30 degrees to the east to better receive sunlight; and so on. In this way, in a cycle of the sun rising in the east and setting in the west, it can always be ensured that the photovoltaic panel 101 is facing the sun, so that the photovoltaic panel 101 can convert more solar energy and improve the working efficiency of the photovoltaic panel 101.

[0049] In the above steps, the main purpose is to improve the power generation effect of the photovoltaic panel 101, so the above steps are performed during the daytime. During the daytime, the working efficiency of the bladeless wind power generation device 2 is low and the upper limit of the improvement is not high, while the upper limit of the improvement of the photovoltaic panel 101 is high, so it is chosen to improve the working efficiency of the photovoltaic panel 101 during the daytime.

[0050] The control method of the hybrid power generation system based on bladeless wind power generation and photovoltaic power generation described above is a control method under normal circumstances. In some special cases, such as cloudy days and when there is no sunlight during the day, the control method of steps 101 to 103 can be used all day long without considering the working efficiency of the photovoltaic panel 101, and it can be used only as a tool to improve the bladeless wind power generation device 2. Or when the wind is strong during certain daytime hours, if the power generation effect of improving the bladeless wind power generation device 2 is better than the power generation effect of improving the photovoltaic panel 101, then the priority can also be changed, and the control method of steps 101 to 103 can be used preferentially during the day.

[0051] In summary, the present invention provides a hybrid power generation system based on bladeless wind power generation and photovoltaic power generation and a control method thereof, which combines bladeless wind power generation and photovoltaic power generation, and can not only obtain the electricity generated by the two power generation methods at the same time, but also can have a good influence on the bladeless wind generator by adjusting the direction of the photovoltaic panel, so that the effective wind force received by the bladeless wind generator is stronger, thereby enhancing the effect of bladeless wind power generation, so that the effect of one plus one is greater than two. Furthermore, the photovoltaic panel itself can also better receive solar energy by adjusting the direction, making the effect of photovoltaic power generation stronger.
