[0035] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0036] As Figures 1-4As shown, it shows a wind collecting mechanism for efficient micro-wind power generation in an embodiment of the present disclosure, including a first wind collecting cylinder 1, the first wind collecting cylinder 1 has a first channel 100, the first channel 100 has a first wind collecting channel 102 and a first wind guiding channel 103 in turn, the first wind collecting channel 102 has a first wind collecting inlet 101, the first wind guiding channel 103 has a first wind guiding outlet 104; the first wind guiding outlet 104 leads to a first turbine rotor 2, the first turbine rotor 2 is used to rotate and generate electricity; a support plate 12 supports the first wind collecting cylinder 1; the support plate 12 is arranged on a connecting part 13.
[0037] In the wind collecting mechanism for efficient micro-wind power generation, first of all, the first wind collecting cylinder 1 has a first channel 100 inside. The first channel 100 is in turn connected to the first wind collecting channel 102 and the first wind guiding channel 103. The front end of the first wind collecting channel 102 is provided with the first wind collecting inlet 101 for receiving external wind power, and the rear end of the first wind guiding channel 103 has the first wind guiding outlet 104.
[0038] The first wind guiding outlet 104 directly leads to the first turbine rotor 2. When the external micro-wind enters the first wind collecting channel 102 through the first wind collecting inlet 101 and then flows out from the first wind guiding outlet 104 through the first wind guiding channel 103, the wind power will drive the first turbine rotor 2 to rotate, thereby realizing power generation.
[0039] In order to support the whole first wind collecting cylinder 1, the support plate 12 is arranged. The support plate 12 is installed on the connecting part 13, which ensures the stability of the first wind collecting cylinder 1 and the whole power generation structure.
[0040] In actual application scenarios, such as in areas where wind resources are relatively weak but relatively continuous, the first wind collecting cylinder 1 of the device can effectively collect and converge micro-wind. Through the guidance and concentration of wind power by the first wind collecting channel 102 and the first wind guiding channel 103, the wind blown out from the first wind guiding outlet 104 has stronger driving force, which can fully drive the first turbine rotor 2 to rotate and generate electricity.
[0041] The advantages of this design are: first, through the special design of the first wind collecting cylinder 1 and the first channel 100, the collection and utilization efficiency of micro-wind energy is improved, and effective power generation under low wind speed conditions is realized. Second, the support structure of the support plate 12 and the connecting part 13 ensures the stability and reliability of the device under various environmental conditions, reduces the reduction of power generation efficiency and potential safety hazards caused by device shaking or instability.
[0042] For example, in some remote mountainous areas or small monitoring sites on the sea, this micro-wind power generation device can operate stably and provide continuous and reliable power supply for local equipment.
[0043] The technical effect is to significantly enhance the power generation capacity in a breeze environment, while improving the stability and durability of the device. The overall working principle: the external breeze enters from the first wind collection inlet 101, passes through the first wind collection duct 102 and the first wind guide duct 103 in turn, blows out from the first wind guide outlet 104 and drives the first turbine rotor 2 to rotate to generate electricity. The entire structure is stably supported by the support plate 12 and the connecting part 13. The overall technical effect: through the above design, the performance of the micro-wind power generation device is optimized, which can better adapt to different wind conditions, providing a more effective solution for the use of renewable energy.
[0044] In some examples, a first fairing 3 is also included, and the first turbine rotor 2 is located inside the first fairing 3, and the first turbine rotor 2 leads to the first fairing 3.
[0045] In this efficient wind collection mechanism for micro-wind power generation, a first fairing 3 is also added. The first turbine rotor 2 is placed inside the first fairing 3 and is in communication with the first fairing 3.
[0046] During actual operation, after the breeze is guided and accelerated by the first wind collection cylinder 1, it blows out from the first wind guide outlet 104 and acts on the first turbine rotor 2. At this time, the first fairing 3 plays an important role.
[0047] The first fairing 3 can further straighten and optimize the flow direction of the incoming wind, making the wind force acting on the first turbine rotor 2 more uniform and stable. This helps to improve the rotation efficiency and power generation effect of the first turbine rotor 2.
[0048] For example, in the case of unstable wind direction or fluctuating wind force, the first fairing 3 can reduce the turbulence and dispersion of the wind force, ensuring that the first turbine rotor 2 can continuously and stably receive effective wind force driving.
[0049] The advantages of this design are: first, it enhances the stability and uniformity of the wind force acting on the first turbine rotor 2, thereby improving the power generation efficiency. Second, it provides certain protection to the first turbine rotor 2, reducing interference and damage from external factors.
[0050] For example, in harsh weather conditions or dusty environments, the first fairing 3 can prevent dust and debris from directly affecting the normal operation of the first turbine rotor 2.
[0051] Technical effect: significantly improves the power generation performance and stability of the device in complex wind conditions. Overall working principle: the breeze passes through the first wind collecting cylinder 1 in turn, and then is uniformly and stably pushed to rotate the first turbine rotor 2 to generate electricity under the rectifying action of the first flow guide cover 3. Overall technical effect: by adding the first flow guide cover 3, the wind power utilization efficiency and operation stability of the device are further optimized, and the overall performance and reliability of the power generation device are improved.
[0052] In some examples, a wind guide cylinder 4 is also included, which is arranged on the connecting part 13 and is arranged inside the first channel 100 and forms a first wind collecting channel 102 and a first wind guiding channel 103 with the first wind collecting cylinder 1.
[0053] In the high-efficiency wind collecting mechanism for micro wind power generation, a wind guide cylinder 4 is also added. The wind guide cylinder 4 is installed on the connecting part 13 and located inside the first channel 100 of the first wind collecting cylinder 1. The wind guide cylinder 4 and the first wind collecting cylinder 1 together form a first wind collecting channel 102 and a first wind guiding channel 103.
[0054] In actual work, for example, when the breeze enters the device, the wind first enters through the first wind collecting inlet 101 of the first wind collecting cylinder 1. Due to the presence of the wind guide cylinder 4, the flow path of the wind in the first wind collecting channel 102 and the first wind guiding channel 103 is further optimized.
[0055] The function of the wind guide cylinder 4 is to more accurately guide the flow direction and flow rate of the wind, so that the wind can more effectively act on the first turbine rotor 2.
[0056] The advantages of this design are: first, through the cooperation of the wind guide cylinder 4 and the first wind collecting cylinder 1, the flow efficiency of the wind in the wind channel is further improved, and the loss of wind energy is reduced. Second, the adaptability of the device to different wind directions and wind speeds is enhanced, so that stable power generation performance can be guaranteed in various wind conditions.
[0057] For example, in an environment where the wind direction frequently changes or the wind speed is unstable, the wind guide cylinder 4 can help stabilize the airflow in the wind channel and ensure that the first turbine rotor 2 continuously obtains effective driving force.
[0058] Technical effect: significantly improves the wind energy utilization efficiency and power generation stability of the device in complex wind conditions. Overall working principle: the breeze enters from the first wind collecting inlet 101 and flows in the wind channel formed by the wind guide cylinder 4 and the first wind collecting cylinder 1, and finally drives the first turbine rotor 2 to rotate to generate electricity, and the entire structure is supported by the connecting part 13. Overall technical effect: by introducing the wind guide cylinder 4, the wind channel structure and performance of the device are improved, and the power generation efficiency and reliability of the device are improved.
[0059] In some examples, the first turbine rotor 2 is arranged on a generator set 14, and the generator set 14 is arranged in the wind guide cylinder 4.
[0060] In the high-efficiency wind power generation wind collecting mechanism, the first turbine rotor 2 is arranged on the generator set 14, and the entire generator set 14 is arranged in the wind guide cylinder 4.
[0061] In actual operation, when the wind drives the first turbine rotor 2 to rotate through the cooperation of the first wind collecting cylinder 1, the first wind guide cover 3, and the wind guide cylinder 4, the rotation energy of the first turbine rotor 2 can be directly transmitted to the generator set 14 located in the wind guide cylinder 4.
[0062] The advantages of this design are: first, placing the generator set 14 in the wind guide cylinder 4 can effectively utilize space and make the structure of the entire device more compact. Second, it reduces the loss in the energy transmission process and improves the power generation efficiency. Third, the wind guide cylinder 4 provides certain protection for the generator set 14, reducing the influence of the external environment on it.
[0063] For example, in harsh weather conditions, the wind guide cylinder 4 can reduce the erosion and damage of rainwater, dust, and the like to the generator set 14.
[0064] In terms of technical effects, the energy conversion efficiency and stability of the device are significantly improved, and the environmental adaptability of the device is enhanced. The overall working principle is that the wind drives the first turbine rotor 2 to rotate, which drives the generator set 14 to generate electricity in the wind guide cylinder 4. The overall technical effect is that through this reasonable layout and design, the power generation performance of the device is optimized, and the reliability and service life of the device are improved.
[0065] In some examples, the second wind collecting cylinder 5 is further included, the support plate 12 supports the second wind collecting cylinder 5, and the second wind collecting cylinder 5 is arranged outside the first wind collecting cylinder 1 to form a second channel 500 with the first wind collecting cylinder 1. The second channel 500 has a second wind collecting channel 502 and a second wind guiding channel 503 connected in sequence. The second wind collecting channel 502 has a second wind collecting inlet 501, and the second wind guiding channel 503 has a second wind guiding outlet 504. The second wind guiding outlet 504 leads to a second turbine rotor 6 for generating electricity after rotation, and the first wind guide cover 3 also leads to the second turbine rotor 6. The second wind guiding outlet 504 is located around the first wind guide cover 3.
[0066] In the high-efficiency wind power generation wind collecting mechanism, a second wind collecting cylinder 5 and a second turbine rotor 6 are added. The support plate 12 not only supports the first wind collecting cylinder 1, but also supports the second wind collecting cylinder 5. The second wind collecting cylinder 5 is arranged outside the first wind collecting cylinder 1, and a second channel 500 is formed between the two. The second channel 500 is composed of a second wind collecting channel 502 and a second wind guiding channel 503 in sequence. The second wind collecting channel 502 has a second wind collecting inlet 501, and the second wind guiding channel 503 has a second wind guiding outlet 504. The second wind guiding outlet 504 leads to the second turbine rotor 6, which is used to rotate and generate electricity. At the same time, the first flow guide 3 also leads to the second turbine rotor 6, and the second wind guiding outlet 504 is located around the first flow guide 3.
[0067] In actual operation, when the wind enters, part of the wind acts on the first turbine rotor 2 through the first wind collecting cylinder 1 to generate electricity. Another part of the wind enters the second wind collecting channel 502 through the second wind collecting inlet 501, and then flows out from the second wind guiding outlet 504 through the second wind guiding channel 503 to drive the second turbine rotor 6 to rotate and generate electricity. The first flow guide 3 also plays a certain role in guiding and optimizing the wind power.
[0068] The advantages of this design are: first, by setting the second wind collecting cylinder 5 and the second turbine rotor 6, the utilization of wind energy is increased, and the overall power generation efficiency is improved. Second, the space of the equipment is fully utilized, and more energy conversion is realized without significantly increasing the size of the equipment. Third, the first flow guide 3 simultaneously optimizes the wind power effect of the first turbine rotor 2 and the second turbine rotor 6, improving the comprehensive performance of the equipment.
[0069] For example, in an environment where the wind resources are relatively stable but not particularly strong, this design of double wind collecting cylinders and double turbine rotors can more fully capture and utilize wind energy, increasing the total power generation.
[0070] In terms of technical effects, the wind energy utilization efficiency and total power generation capacity of the equipment are significantly improved. The overall working principle: the wind drives the first turbine rotor 2 and the second turbine rotor 6 to rotate and generate electricity through the first wind collecting cylinder 1 and the second wind collecting cylinder 5, and the first flow guide 3 optimizes the wind power effect. The entire structure is supported by the support plate 12. The overall technical effect: through the above design, the power generation performance and energy utilization rate of the equipment are effectively improved, and the adaptability of the equipment in different wind conditions is enhanced.
[0071] In some examples, a third wind collecting cylinder 7 is also included, supported by the support plate 12, and the second wind collecting cylinder 5 is arranged outside the second wind collecting cylinder 5, forming a third channel 700 between the second wind collecting cylinder 5 and the third wind collecting cylinder 7, which has a third wind collecting channel 702 and a third wind guiding channel 703 connected in sequence, the third wind collecting channel 702 has a third wind collecting inlet 701, and the third wind guiding channel 703 has a third wind guiding outlet 704; the third wind guiding outlet 704 leads to a third turbine rotor 8 for rotating to generate electricity.
[0072] In the high-efficiency wind power generation wind collecting mechanism, a third wind collecting cylinder 7 and a third turbine rotor 8 are added. The support plate 12 not only supports the first wind collecting cylinder 1 and the second wind collecting cylinder 5, but also supports the third wind collecting cylinder 7. The third wind collecting cylinder 7 is arranged outside the second wind collecting cylinder 5, forming a third channel 700 between the second wind collecting cylinder 5 and the third wind collecting cylinder 7.
[0073] The third channel 700 is composed of a third wind collecting channel 702 and a third wind guiding channel 703 connected in sequence, wherein the third wind collecting channel 702 has a third wind collecting inlet 701, and the third wind guiding channel 703 has a third wind guiding outlet 704. The third wind guiding outlet 704 leads to a third turbine rotor 8 for rotating to generate electricity.
[0074] In actual work, when the wind enters the device, part of the wind passes through the first wind collecting cylinder 1, the second wind collecting cylinder 5, and the third wind collecting cylinder 7 in sequence. The wind enters the third wind collecting channel 702 from the third wind collecting inlet 701, passes through the third wind guiding channel 703, and flows out from the third wind guiding outlet 704, thereby driving the third turbine rotor 8 to rotate for power generation.
[0075] The advantages of this design are: first, through the arrangement of multiple layers of wind collecting cylinders and multiple turbine rotors, the efficiency of wind energy collection and utilization is further improved, and the total power generation is increased. Second, it makes full use of the external space of the device, realizing the maximum energy conversion in a limited volume. Third, it can adapt to a wider range of wind conditions and effectively generate electricity under different wind speeds.
[0076] For example, in open plain areas, even if the wind speed is relatively low and unstable, the multi-layer structure design can ensure stable output of electric energy.
[0077] In terms of technical effects, the power generation capacity and adaptability of the device are significantly enhanced. The overall working principle: the wind passes through each layer of wind collecting cylinders in sequence, driving the corresponding turbine rotors to rotate and generate electricity, and the support plate 12 ensures the stability of the entire structure. The overall technical effect: through the design of multiple layers of wind collecting cylinders and multiple turbine rotors, the overall performance of the device is improved, making it more efficient and reliable in wind energy utilization.
[0078] In some examples, a second guide cover 9 is also included, the second turbine rotor 6 is located in the second guide cover 9, the second air guide outlet 504 leads to the second turbine rotor 6, and the second turbine rotor 6 leads to the second guide cover 9; the second guide cover 9 also leads to the third turbine rotor 8, and the third air guide outlet 704 is located around the second guide cover 9; the third turbine rotor 8 is located in the third guide cover 10, the third air guide outlet 704 leads to the third turbine rotor 8, and the third turbine rotor 8 leads to the third guide cover 10. The first, second, and third air guide tubes 1, 5, and 7 are all trumpet-shaped, so that the first, second, and third air ducts 100, 500, and 700 are all gradually reduced in the direction of the wind. This allows smaller wind power to achieve greater output torque.
[0079] In the high-efficiency wind power generation air guide device, a second guide cover 9 and a third guide cover 10 are also added. The second turbine rotor 6 is located in the second guide cover 9, and the wind from the second air guide outlet 504 passes through the second turbine rotor 6, and the second turbine rotor 6 also leads to the second guide cover 9. At the same time, the second guide cover 9 also leads to the third turbine rotor 8, and the third air guide outlet 704 is located around the second guide cover 9. The third turbine rotor 8 is located in the third guide cover 10, the wind from the third air guide outlet 704 passes through the third turbine rotor 8, and the third turbine rotor 8 leads to the third guide cover 10.
[0080] In actual operation, when the wind flows out from the second air guide outlet 504, it can be more effectively concentrated on the second turbine rotor 6 under the action of the second guide cover 9, improving the rotation efficiency and power generation effect of the second turbine rotor 6. Moreover, the wind after passing through the second turbine rotor 6 can flow more smoothly to the third turbine rotor 8 under the guidance of the second guide cover 9, improving the wind energy utilization efficiency of the third turbine rotor 8.
[0081] Similarly, the third guide cover 10 plays a role in rectifying and optimizing the flow direction of the wind flowing out from the third air guide outlet 704, making the wind more efficiently drive the third turbine rotor 8 to rotate and generate electricity.
[0082] The advantages of this design are: first, the setting of the guide cover can make the wind more concentrated and uniform on the turbine rotor, improving the wind energy utilization efficiency and power generation effect. Second, the adjacent guide covers cooperate with each other to realize the orderly transmission and utilization of wind energy, reducing the loss and waste of wind energy. Third, it provides certain protection for the turbine rotor, reducing the risk of interference and damage from external factors.
[0083] For example, in areas with strong winds and variable wind directions, the guide cover can make the equipment run more stably and reduce the fluctuation of power generation efficiency caused by changes in wind direction.
[0084] The technical effect is that the power generation performance and stability of the device under different wind conditions are significantly improved. The overall working principle: the wind passes through each wind collecting cylinder and wind guiding channel in turn, and under the action of the fairing, each turbine rotor is efficiently driven to rotate and generate electricity. The overall technical effect: by adding the fairing, the wind energy utilization and power generation efficiency of the device are further optimized, and the reliability and adaptability of the device are enhanced.
[0085] In some examples, a top cover 11 is further included, which is arranged on the connecting part 13 and forms a wind diffusing channel 1101 between the third fairing 10, the wind diffusing channel 1101 having a plurality of circumferentially arranged wind diffusing openings 1102; the third fairing 10 has a plurality of circumferentially arranged guiding openings 1001 leading to the wind diffusing channel 1101.
[0086] In the high-efficiency wind power generation wind collecting mechanism, the top cover 11 is installed on the connecting part 13. The top cover 11 and the third fairing 10 form a wind diffusing channel 1101, and the wind diffusing channel 1101 has a plurality of circumferentially arranged wind diffusing openings 1102. At the same time, the third fairing 10 also has a plurality of circumferentially arranged guiding openings 1001, which lead to the wind diffusing channel 1101.
[0087] In actual operation, after the wind passes through each level of wind collecting cylinder and turbine rotor, it finally enters the wind diffusing channel 1101 through the guiding openings 1001 of the third fairing 10 and is discharged from the wind diffusing openings 1102 of the wind diffusing channel 1101.
[0088] The advantages of this design are: first, the arrangement of the wind diffusing channel 1101 and the wind diffusing opening 1102 can effectively and orderly discharge the wind after the power generation process, reduce wind resistance and backflow, and improve the operating efficiency of the entire system. Second, the circumferentially arranged wind diffusing openings 1102 and guiding openings 1001 can ensure that the wind is discharged and entered more uniformly and stably, reducing airflow turbulence and energy loss. Third, the cooperation of the top cover 11 and the third fairing 10 forms a relatively closed wind diffusing channel, which helps to reduce noise and optimize the working environment of the device.
[0089] For example, in the case of large and continuous wind volume, this wind diffusing structure can quickly and effectively discharge the wind, avoid excessive internal pressure, and ensure the stable operation and power generation efficiency of the device.
[0090] Technical effect: significantly improve the device's wind effect and running stability, reduce the noise level. Overall working principle: after the wind completes the mission of driving the turbine rotor to generate electricity, it enters the wind diffuser tunnel 1101 through the guide port 1001, and then is discharged through the wind diffuser port 1102, realizing the orderly dispersion of the wind. Overall technical effect: through the design of the top cover 11 and the wind diffuser tunnel 1101, the wind path structure of the device is improved, and the comprehensive performance and working reliability of the device are improved.
[0091] In some examples, the first fairing 3 and the second fairing 9 include a cylindrical section 301 and a converging section 302 that are sequentially connected, the first turbine rotor 2 and the second turbine rotor 6 are located in the first fairing 3, the converging section 302 gradually decreases in cross-sectional area from close to the cylindrical section 301 to away from the cylindrical section 301, and the inner wall of the cylindrical section 301 has a plurality of circumferentially arranged guide strips 303, which are helical.
[0092] In the high-efficiency wind power generation wind collecting mechanism, the first fairing 3 and the second fairing 9 are composed of a cylindrical section 301 and a converging section 302 that are sequentially connected. The first turbine rotor 2 and the second turbine rotor 6 are located in the corresponding fairing. The converging section 302 gradually decreases in cross-sectional area from close to the cylindrical section 301 to away from the cylindrical section 301. The inner wall of the cylindrical section 301 has a plurality of circumferentially arranged helical guide strips 303.
[0093] In actual operation, when the wind enters the fairing, it first passes through the cylindrical section 301. The helical guide strips 303 on the inner wall of the cylindrical section 301 can guide and accelerate the wind, making the wind flow more orderly and forming a certain rotating airflow. Then, the wind enters the converging section 302, and due to the gradually decreasing cross-sectional area, the flow rate of the wind is further increased, thereby more powerfully driving the turbine rotor to rotate.
[0094] The advantages of this design are: first, the helical guide strips 303 can optimize the flow path of the wind and improve the energy utilization rate of the wind. Second, the structure of the converging section 302 can enhance the driving force of the wind and improve the rotational speed and power generation efficiency of the turbine rotor. Third, this special structure of the fairing can adapt to changes in wind speed and direction, improving the stability and adaptability of the device.
[0095] For example, in the case of low wind speed, the cooperation of the guide strips 303 and the converging section 302 can effectively concentrate and enhance the wind energy, so that the device can still maintain good power generation effect.
[0096] Technical effect: significantly improves the guiding and enhancing effect of the fairing on the wind, thereby improving the power generation performance of the turbine rotor and the overall efficiency of the equipment. Overall working principle: the wind is guided and accelerated by the guide strip 303 in the cylindrical section 301 of the fairing, and then further accelerated in the necked section 302 to drive the turbine rotor to rotate and generate electricity. Overall technical effect: by optimizing the structure of the fairing, the utilization efficiency of wind energy is improved, and the power generation capacity and stability of the equipment under different wind conditions are enhanced.
[0097] In some examples, the support plates 12 are plate-shaped, flat plate-shaped or spiral plate-shaped, arranged in several circumferential rows, separating the annular first channel 100, second channel 500 and third channel 700 into several circumferentially arranged sub-channels 105. In the high-efficiency wind power generation wind collecting mechanism, the support plates 12 are plate-shaped and arranged in several circumferential rows. These support plates 12 separate the annular first channel 100, second channel 500 and third channel 700 into several circumferentially arranged sub-channels 105.
[0098] In actual work, when the wind enters each channel, due to the separating effect of the support plates 12, the wind can be more evenly distributed in each sub-channel 105.
[0099] The advantages of this design are: first, it makes the distribution of wind in the channel more uniform, avoiding the situation of large or small local wind, thereby more effectively driving the turbine rotor to rotate and improving the power generation efficiency. Second, it enhances the stability of the entire structure and provides better support for each component. Third, the circumferentially arranged sub-channels 105 help to reduce turbulence and energy loss of the wind in the channel.
[0100] For example, in a strong wind environment, the evenly distributed sub-channels 105 can ensure that the wind force borne by the equipment is more balanced, reducing the risk of structural damage caused by uneven stress.
[0101] Technical effect: significantly improves the uniformity and utilization efficiency of wind energy in the channel, and enhances the structural stability of the equipment. Overall working principle: after the wind enters the channel, it is evenly distributed in each sub-channel 105 under the separation of the support plates 12, driving the turbine rotor to rotate stably and generate electricity. Overall technical effect: by reasonable design of the support plates 12, the wind energy transmission and utilization of the equipment are optimized, and the reliability and power generation performance of the equipment are improved.
