Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and more specifically, to a micro-wind power generation device. Background Technology

[0002] In today's society, with continuously rising energy demand and increasing environmental awareness, the development of renewable energy has become a global focus. Wind power, as an important form of renewable energy utilization, occupies an increasingly important position in the energy sector due to its significant advantages such as being clean, pollution-free, and renewable. In recent years, wind power technology has made significant progress, with the scale of wind power equipment continuously expanding and installed capacity steadily increasing, making important contributions to alleviating energy pressure and reducing carbon emissions. The widespread application of wind power has not only promoted the optimization and upgrading of the energy structure but also stimulated the development of related industries and driven economic growth.

[0003] In the field of wind power generation, various technical means have been adopted to improve power generation efficiency. Traditional wind power generation equipment mostly relies on natural wind to directly drive the wind turbine to rotate and generate electricity. This method is relatively direct, but it requires high wind speeds.

[0004] However, existing wind power generation technologies have significant shortcomings. In light wind environments, traditional methods that directly utilize natural wind suffer from extremely low power generation efficiency due to the low wind speed, making it difficult for the wind turbine to obtain sufficient power and thus failing to fully utilize abundant light wind resources.

[0005] In conclusion, how to achieve efficient power generation in light wind conditions while accurately capturing wind direction is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

An embodiment of this application discloses a micro-wind power generation device.

[0052] The core of this utility model is to provide a micro-wind power generation device.

[0053] Please refer to Figures 1-11 .

[0054] The micro-wind power generation device provided by this utility model includes a wind direction identification component 1, a support frame 301, a rotating disk 303, and a wind gathering component 2. The wind direction identification component 1 is used to identify the wind direction of the area. A rotating shaft is rotatably arranged on the support frame 301, and multiple wind turbines 313 are axially arranged on the rotating shaft. A generator 311 is arranged at the bottom of the support frame 301, and the output shaft of the generator 311 is connected to the rotating shaft through a gearbox 312. The rotating disk 303 is rotatably arranged on the support frame 301, and the wind gathering component 2 is fixedly installed on the rotating disk 303. A first drive motor 305 for rotating the rotating disk 303 and a control module 307 for controlling the first drive motor 305 are provided on the support frame 301. The control module 307 is provided with a signal receiving unit, and the signal receiving unit is electrically connected to the wind direction identification component 1 to receive the wind direction signal from the wind direction identification component 1. The wind gathering component 2 is used to gather and guide the incoming wind to the dynamic surface of the wind turbines 313.

[0055] Specifically, the overall frame of this device includes a support frame 301 at the bottom and a frame 302 at the top. The rotating disk 303 is mounted on the support frame 301. The support frame 301 is also equipped with a first drive motor 305 for driving the rotating disk 303, and a control module 307 for controlling the first drive motor 305 (this control module is a conventional motor control module and will not be described in detail here). A wind concentrator 2 is installed on the frame 302, which can effectively concentrate the wind source it faces to the wind wheel 313.

[0056] The wind turbine 313 is mounted on the support frame 301 via a rotating shaft 3138. The rotating shaft 3138 is vertically rotatable on the support frame 301, and the wind turbines 313 are arranged circumferentially on the rotating shaft 3138. Multiple wind turbines 313 form a wind turbine group. Multiple wind turbine groups are arranged axially on the rotating shaft 3138. A generator 311 (a conventional wind turbine generator, which will not be described in detail here) is connected to the bottom end of the rotating shaft 3138. The rotating shaft 3138 is driven to rotate by the wind turbines 313, thereby driving the generator 311 to generate electricity.

[0057] The device is also equipped with a wind direction identification component 1 on one side of the support frame 301. The wind direction identification component 1 is used to determine the wind direction of its area. At the same time, a synchronization module is also provided between the wind direction identification component 1 and the wind gathering component 2. The synchronization module is used to transmit the wind direction determined by the wind direction identification component 1 to the control module 307, and also rotate the orientation of the wind gathering component 2 to the wind direction to achieve wind gathering.

[0058] Optionally, the support frame 301 includes a base and columns. The base is constructed of cast concrete or welded steel, providing sufficient strength and stability. The columns are vertically mounted on the base and can be made of steel pipes or solid steel columns to provide stable support. A rotating shaft is mounted on the support frame; the shaft can be made of alloy steel, offering high strength and wear resistance. Multiple wind turbines are arranged circumferentially on the shaft, with blades made of composite materials or aluminum alloys to reduce weight and improve aerodynamic performance. A generator is mounted at the bottom of the support frame; the generator can be a permanent magnet synchronous generator or an asynchronous generator. Permanent magnet synchronous generators offer high efficiency and power density, while asynchronous generators have a simple structure and high reliability. The generator's output shaft is connected to the rotating shaft via a gearbox; the gearbox can be a gear transmission or a planetary transmission. Gear transmissions offer high transmission efficiency, while planetary transmissions have a compact structure and a large transmission ratio.

[0059] The aforementioned micro-wind power generation equipment effectively uses the wind direction recognition component 1 to locate the wind direction of the power generation equipment. At the same time, the rotating disk 303 drives the wind gathering component 2 to move and align the wind gathering port with the wind direction recognized by the wind direction recognition component 1, thereby achieving concentrated wind gathering in a micro-wind environment. This allows the wind gathering component 2 to gather a large area of ​​natural wind onto the power surface of the wind turbine 313, increasing the wind speed and achieving efficient power generation in a micro-wind environment, making full use of micro-wind resources.

[0060] The micro-wind power generation equipment provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0061] In one specific implementation, reference is made to... Figure 1 and Figure 11 The wind direction recognition component 1 includes a mounting base 101 and a rotating rod 103. The mounting base 101 has a plurality of third limit switches 102 evenly arranged in the circumferential direction. The rotating rod 103 is rotatably mounted on the shaft of the mounting base 101, and a wind deflector 104 is provided on the rotating rod 103 extending radially outward. A trigger block 105 is provided on the rotating rod 103 on the reverse extension line of the wind deflector 104. A first trigger surface is formed between the trigger block 105 and the third limit switches 102. The width of the first trigger surface is configured according to the spacing between adjacent third limit switches 102 so that the trigger block 105 is always in contact with any one of the third limit switches 102 during rotation.

[0062] Specifically, the mounting base 101 adopts a disc-shaped structure, with multiple third limit switches 102 distributed circumferentially around its outer edge. The spacing between the multiple third limit switches 102 is the same, and each third limit switch 102 represents a wind direction. A rotating rod 103 is vertically arranged in the middle of the mounting base 101, and the rotating rod 103 can rotate on the mounting base 101. A wind deflector 104 is disposed on the rotating rod 103, and a trigger block 105 is disposed on the opposite extension line of the rotating rod 103, also located on the rotating rod 103. The wind will blow the wind deflector 104, causing the rotating rod 103 and the trigger block 105 to rotate. When the wind deflector 104 is parallel to the wind direction, the rotating rod 103 stops rotating, and the trigger block 105 stops rotating and is released from at least one and only one third limit switch 102, thereby realizing the determination of the wind direction.

[0063] A first trigger surface is formed on one end of the trigger block 105 near the third limit switch 102. The width of the first trigger surface is configured according to the spacing between adjacent third limit switches 102 so that the trigger block 105 is always in contact with any third limit switch 102 during rotation. That is, when the front end of the first trigger surface just touches the next third limit switch 102, the end of the first contact surface disengages from the previous third limit switch.

[0064] The center of the rotating disk 303 has a central bearing 319 that can pass through the rotating shaft 3138.

[0065] Optionally, the mounting base 101 can be made of metal, which offers good stability and corrosion resistance. The third limit switch can be either a mechanical or electronic limit switch. Mechanical limit switches are simple in structure and low in cost, while electronic limit switches offer fast response and high precision. The wind deflector can be made of lightweight plastic or carbon fiber, reducing weight while maintaining sufficient strength.

[0066] Based on any of the above embodiments, refer to Figure 4 and Figure 5 The control module 307 includes a fixed pressure plate 308 coaxially arranged with the rotating disk 303, and the fixed pressure plate 308 is fixedly arranged relative to the support frame 301. The fixed pressure plate 308 is circumferentially arranged with a plurality of first limit switches 309, and the first limit switches 309 and third limit switches 102 are arranged in a one-to-one correspondence so that the corresponding first limit switches 309 and third limit switches 102 are at the same angle. The common terminal of the third limit switch 102 is electrically connected to the normally closed terminal of the corresponding first limit switch 309. A protrusion is fixedly arranged on the rotating disk 303, and a second trigger surface is formed between the protrusion and the first limit switch 309. The radial extension direction of the protrusion is consistent with the wind gathering direction of the wind gathering component 2.

[0067] Specifically, the support frame 301 is a box-shaped structure made of cast iron, with an embedded planetary gear transmission 312. Its power input shaft and rotating shaft 3138 are connected by a double-row deep groove ball bearing. The fixed pressure plate 308 is a ring-shaped component made of carbon fiber reinforced composite material. Multiple micro-motion limit switches are distributed in a ring around its outer edge as first limit switches 309. The number of first limit switches 309 is the same as the number of third limit switches 102. Their contact ends form a star-shaped series circuit with the common end of the third limit switches 102. The rotating disk 303 has a copper sleeve-type central bearing 319 at its center and a precision-machined gear ring 304 on its outer edge, which meshes with the reduction gear 306 of the first drive motor 305. The fixed pressure plate 308 is firmly connected to the support frame 301 by the first connecting bolt 300.

[0068] A protrusion 310 is provided on the outer edge of the rotating disk 308. As the rotating disk 303 rotates, the protrusion 310 gradually approaches and eventually triggers the corresponding first limit switch 309 on the fixed pressure plate 308. When the first limit switch 309 on the fixed pressure plate 308 is triggered, its normally closed terminal opens, cutting off the circuit between the first drive motor 305 and the battery used to control the first drive motor 305, and the first drive motor 305 stops running. At this time, the rotating disk 303 stops at the position indicated by the wind deflector 104 on the wind direction recognition component 1.

[0069] Furthermore, a gear ring 304 is fixedly provided on the outer periphery of the rotating disk 303, and a gear 306 is fixedly provided on the output shaft of the first drive motor 305, with the gear 306 meshing with the gear ring 304.

[0070] Specifically, the outer side of the rotating disk 303 has a toothed ring 304 that meshes with the gear 306 of the first drive motor 305, so that the first drive motor 305 drives the rotating disk 303 to rotate, thereby driving the frame 302 to rotate.

[0071] Based on any of the above embodiments, refer to Figure 2 The fixed pressure plate 308 is covered on the rotating disk 303, and a connecting plate is fixedly provided on the outer periphery of the fixed pressure plate 308. The connecting plate is fixedly connected to the support frame 301. The first limit switch 309 is arranged on the side of the fixed pressure plate 308 facing the rotating disk 303, and is configured in conjunction with the protrusion 310.

[0072] Specifically, a fixed pressure plate 308 is mounted on the rotating disk 303, and its outer peripheral connecting plate is fixedly connected to the support frame 301, ensuring the stability of the fixed pressure plate 308 relative to the support frame 301. A first limit switch is located on the side of the fixed pressure plate 308 facing the rotating disk 303, cooperating with a protrusion 310 on the rotating disk 303. When the rotating disk 303 rotates, the protrusion 310 gradually approaches and triggers the corresponding first limit switch 309, thereby controlling the first drive motor 305 to stop operating, stopping the rotating disk 303 in a position consistent with the wind direction. This ensures that the air inlet direction of the wind concentrator 2 is consistent with the wind direction, achieving precise wind direction tracking and improving the utilization efficiency of wind energy.

[0073] The rotating disk 303 is also equipped with multiple support bearings 316 to prevent left and right swaying. The support bearings 316 are fitted around the inner side of the fixed pressure plate 308. The rotating disk 303 is also equipped with a second connecting bolt 318 to firmly connect the frame 302 and the rotating disk 303 together.

[0074] Based on any of the above embodiments, refer to Figure 2 A plurality of first sliding bearings 314 are disposed between the rotating disk 303 and the support frame 301, and the plurality of first sliding bearings 314 are fixedly connected to the rotating disk 303.

[0075] Specifically, when the micro wind power generation equipment is working, the first drive motor 305 drives the rotating disk 303 to rotate. At this time, the first sliding bearing 314 slides on the support frame 301. Since the first sliding bearing 314 is fixedly connected to the rotating disk 303, it can effectively reduce the friction between the rotating disk 303 and the support frame 301, ensuring that the rotating disk 303 rotates smoothly on the support frame 301. This allows the wind gathering component 2 installed on the rotating disk 303 to flexibly adjust its direction and better gather the wind onto the wind turbine 313, thereby improving the power generation efficiency.

[0076] Based on any of the above embodiments, refer to Figure 1 A plurality of second sliding bearings 315 are disposed between the fixed pressure plate 308 and the rotating plate 303, and the plurality of second sliding bearings 315 are fixedly connected to the fixed pressure plate 308.

[0077] Specifically, multiple second sliding bearings 315 are fixed on the fixed pressure plate and positioned between the fixed pressure plate 308 and the rotating disk 303. When the first drive motor 305 drives the rotating disk 303 to rotate, the second sliding bearings 315 serve two purposes: firstly, they press down on the rotating disk 303, stabilizing it between the fixed pressure plate and the support frame 301; secondly, their close contact with the surface of the rotating disk 303 reduces the friction between the rotating disk 303 and the fixed pressure plate 308 during rotation, resulting in smoother rotation of the rotating disk 303 and ensuring the stability and flexibility of the micro-wind power generation equipment when adjusting the direction of the wind-gathering components.

[0078] Based on any of the above embodiments, the wind concentrator 2 includes a wind concentrator frame and a drive assembly. The wind concentrator frame is fixedly mounted on the rotating disk 303. There are two wind concentrator frames, which are arranged to converge toward the impeller 313. An air flow channel is formed between the two wind concentrator frames so that the inner side of the two wind concentrator frames is connected to the air inlet of the impeller 313. The surface of each wind concentrator frame is hollowed out to form a hollow area. Multiple slides are provided on the wind concentrator frame along the extension direction. At least one wind concentrator plate 204 is slidably disposed in each slide. The drive assembly is used to drive the sliding of the wind concentrator plate 204 in the corresponding slide to realize the opening or closing of the hollow area.

[0079] Specifically, the wind concentrator is fixedly mounted on the rotating disk 303, with two concentrators arranged converging towards the wind turbine 313, forming an airflow channel between them and connecting to the air inlet of the wind turbine 313. The surface of the wind concentrator is perforated to form a hollow area, and multiple tracks are provided along its extension direction. At least one wind concentrator plate 204 is slidably mounted in each track. The drive assembly can drive the wind concentrator plate 204 in the corresponding track to slide, thus opening or closing the hollow area. This configuration allows for flexible adjustment of the wind concentrator component 2's wind-gathering effect according to actual wind conditions. When the wind is weak, the hollow area is closed, concentrating more wind at the air inlet of the wind turbine 313, increasing wind speed, and achieving efficient power generation even in light winds.

[0080] Based on any of the above embodiments, the slide includes an upper slide 200 and a lower slide 202 disposed opposite to each other on the wind-gathering frame 201, and the wind-gathering plate 204 is disposed between the upper slide 200 and the lower slide 202.

[0081] Specifically, the upper slide rail 200 and the lower slide rail 202 are arranged opposite to each other on the wind-gathering frame, and the wind-gathering plate 204 is arranged between the upper slide rail 200 and the lower slide rail 202. This arrangement provides a sliding track for the wind-gathering plate 204, allowing the wind-gathering plate 204 to slide smoothly along the slide rail, thereby realizing the opening or closing of the hollow area of ​​the wind-gathering component 2. In turn, it avoids excessive resistance affecting the rotation of the wind-gathering frame during the rotation process.

[0082] A V-shaped slide rail 212 is provided in the lower slide rail 202 or the upper slide rail 200. V-shaped pulleys 213 are installed above and below the wind deflector 204. The V-shaped pulleys 213 are installed in the V-shaped slide rail 212.

[0083] Based on any of the above embodiments, the drive assembly includes two adjusting gears 205 disposed on the wind-gathering frame. The two adjusting gears 205 are respectively located at the end of the stroke and the beginning of the stroke of the slide. A rack 206 is connected between the two adjusting gears 205. The rack 206 is fixedly connected to the side of the outermost wind-gathering plate 204 away from the other wind-gathering plates 204 in the working mode. Each adjacent wind-gathering plate 204 is provided with a slide groove parallel to the slide and a slider slidably disposed in the slide groove. The stroke of the slide groove is the same as the width of the wind-gathering plate 204.

[0084] Specifically, the two adjusting gears 205 of the drive assembly are mounted on the air-gathering frame, located at the end and beginning of the slide's stroke, respectively. The two adjusting gears 205 are connected via a rack 206, which is fixedly connected to the side of the outermost air-gathering plate 204 facing away from the other air-gathering plates 204 in the working mode. A groove parallel to the slide is provided between adjacent air-gathering plates 204, containing a slider, and the stroke of the groove is the same as the width of the air-gathering plate. When the second drive motor 207 drives the adjusting gears 205 to rotate, it moves the rack 206, thereby causing the outermost air-gathering plate 204 to slide within the slide. Since adjacent air-gathering plates are connected by the groove and slider, when the previous air-gathering plate 204 reaches the end of its stroke, the next air-gathering plate 204 continues to move the previous one backward, thus retracting multiple air-gathering plates 204 into one, opening or closing the hollow area. The frame control assembly 216 (a conventional motor control assembly) controls the operation of the second drive motor 207.

[0085] It should be noted that the generator 311 is equipped with a central shaft tube 3131 and fan blades 3132. The wind turbine 313 consists of at least one set of fan blades 3132, with each set having at least two fan blades 3132. The fan blades 3132 are arc-shaped, and each set of fan blades 3132 has a central shaft hole 3131 at its center. A through-hole 3133 is left at the connection between the fan blades 3132 and the central shaft hole 3131. A power shaft 3138 is installed inside the central shaft hole 3131. The wind turbine 313 is vertically mounted on the same power shaft 3138, and the fan blades 3132 of the upper and lower sets of wind turbines 313 are installed in a staggered manner. When wind acts on the fan blades of the wind turbine 3132, the wind turbine 3132 begins to rotate, transmitting mechanical energy to the generator 311 through the transmission system. The coil inside the generator 311 rotates in a magnetic field, generating electrical energy according to the principle of electromagnetic induction.

[0086] It should also be noted that the control module 307 also includes a battery, a generator, a wireless receiver, a forward / reverse controller 211, a first relay 209, and a second relay 210. When the wind direction changes, the wind deflector 104 rotates, which in turn triggers the third limit switch 102 via the trigger block 105, and simultaneously triggers the time-delay relay and the wireless transmitter. The time-delay relay provides delayed power to the first drive motor 305. Simultaneously, the wireless transmitter sends a signal to the wireless receiver at the top of the frame 302. Upon receiving the signal, the wireless receiver triggers both the first relay 209 and the second relay 210. The forward / reverse controller 211 connects the first relay 209 and the second relay 210. Under the control of the forward / reverse controller 211, the first relay 209 begins to discharge to the second drive motor 207. The second drive motor rotates, causing the air-gathering component 2 to retract. When the air-gathering component 2 has retracted completely, the time-delay relay activates to control the first drive motor 305 to rotate. Simultaneously, the rotating disk 303 rotates together with the frame 302. When the side of the frame 302 equipped with the air-gathering component 2 aligns with the direction indicated by the wind deflector 104, the rotating disk 303... The second trigger module 310 on the 3rd floor triggers the first limit switch 309 installed on the fixed pressure plate 308. At this time, the normally closed end of the first limit switch 309 on the fixed pressure plate 308 is triggered and de-energized. The first drive motor 305 stops working, and the second relay 210 starts working. The second relay 210 is connected to the reverse end of the forward and reverse controller 211 and starts to discharge to the second drive motor 207. This reverses the wind gathering component 2 and expands it. On the one hand, it gathers a large area of ​​natural wind in front of the force-bearing surface of the wind wheel 313 to increase the wind speed. On the other hand, it blocks the rotation surface of the wind wheel 313 to reduce resistance. When the wind blows over the wind wheel 313, the wind wheel 313 drives the generator 311 on the base 301 to rotate through the power shaft 3138 to generate electricity and realize micro-wind power generation.

[0087] The implementation principle of a micro-wind power generation device according to an embodiment of this application is as follows: Natural wind blows the wind deflector 104, causing the rotating rod 103 to deflect. The protrusion of the trigger block 105 sequentially contacts the third limit switch 102 in the corresponding position. The switch signal is transmitted to the first drive motor 305 via a wire, thereby adjusting the angle of the rotating disk 303 until the first limit switch 309 on the fixed pressure plate 308 corresponding to the wind direction is pressed down by the protrusion of the rotating disk 303 to complete the positioning. At this time, the wind concentrator 204 unfolds outward under the action of the drive component. During the rotation, the wind concentrator 204 retracts to reduce the resistance during the rotation process, guides the airflow into the air inlet of the wind turbine 313, and the blades rotate under force to generate kinetic energy output, thereby achieving the effect of concentrating a micro-wind.
