Description

Technical Field

[0001] This invention relates to the field of new energy power generation equipment technology, and specifically to a new energy power generation device installed on a light pole. Background Technology

[0002] Highway service areas, as supporting facilities for highways, are complete and independent closed systems, while also serving as open hubs for public vehicles. In the future, with the rise of big data and new energy, the role of highway service areas as gateways will become increasingly important. With the deployment of various electronic devices and the growing trend of new energy vehicles replacing gasoline vehicles, the demand for electricity in both highways and service areas is increasing exponentially. Currently, besides grid power, the main sources of electricity are renewable energy, including traditional solar power. However, power generation is limited by wind, rain, and lack of sunshine. While weather conditions are generally categorized as sunny, cloudy, and rainy, wind power is feasible in any weather, as long as there is wind. Therefore, to ensure the ability to generate electricity using natural energy sources 24 hours a day, rather than relying entirely on grid power, and to supplement the self-sufficiency of highway service areas and other key transportation routes, it is essential to convert natural energy sources such as solar and wind power into storable electrical energy.

[0003] Existing technologies include multi-functional smart light poles, one of the key features of which is the integration of power generation and intelligent modules. These modules combine wind power, solar power, communication, advertising, and high-definition cameras onto a single pole, showcasing high intelligence and integration. Individually, these modules can operate independently, while together they can perform multiple functions, especially in wartime where they can play a unique and flexible role. The prerequisite for the safe, independent, and continuous operation of these intelligent functions is energy self-sufficiency. However, the deployment of power generation equipment on traditional light poles in highway service areas is problematic. Traditional wind power units often rely on mechanical bearings, leading to issues such as high frictional losses, difficulty starting in light winds, easy wear, and frequent maintenance. Furthermore, some light poles have limited power generation capacity; for example, relying solely on wind power results in low efficiency and difficulty in generating electricity naturally in weak winds. This is because traditional wind turbine rotors, due to their bearing-based mounting, have a high critical torque, requiring a certain level of wind strength to rotate and generate electricity, thus imposing relatively strict limitations on power generation conditions. Additionally, different locations... The wind speed varies greatly depending on the wind conditions, and how to adapt the power generation performance according to the wind speed is also a problem. If the rotor rotation damping is large, the starting wind speed for power generation will be relatively high, resulting in a lower total power generation and making it difficult to promote its use in some areas with light winds. However, if the rotation damping is too small, not only will the manufacturing and installation costs be high, but it may also lead to increased and unadjustable vibrations under strong winds. Therefore, it is best to have both a small rotor rotation damping and the ability to adjust the rotation damping size to adapt to the specific working environment, thereby ensuring that the reliability of wind power generation and the starting power generation capacity of the wind turbine are balanced as much as possible. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a new energy power generation device installed on a light pole to solve the problem of low power generation performance of existing power generation equipment installed on light poles, especially in wind power generation, where the large rotational damping results in a large constraint on power generation performance due to wind force, making it difficult to flexibly adapt to light wind environments.

[0005] This invention is achieved through the following technical solution: A new energy power generation device installed on a light pole includes a core tube, inner magnetic rings, and outer magnetic rings. Several inner magnetic rings are coaxially fixedly fitted on the core tube along its axial direction, and coils are provided on the core tube between adjacent inner magnetic rings. A sleeve is also fitted on the outside of the core tube without contacting it. Several fan blades are integrally fixed on the outer wall of the sleeve, and an outer magnetic ring is fixed in the inner wall of the sleeve. All inner magnetic rings and coils are located inside the outer magnetic ring. Flange plates that are detachably fixed to the light pole are fixed at both ends of the sleeve. On the end faces of the flange plates and the sleeve that are directly opposite each other, an end face magnetic ring is coaxially installed. At least one end face magnetic ring can change its position axially so that the sleeve is in a suspended installation state outside the core tube, where it can rotate when the fan blades are blown by the wind.

[0006] Furthermore, each end of the core tube has a circular socket, and the end face of the flange plate has a cylindrical stepped portion. The stepped portion is coaxially and fixedly inserted into the socket to achieve coaxial fixation between the flange plate and the end of the core tube.

[0007] Furthermore, an annular groove is provided on the bottom end face of the upper flange plate near the edge at the upper end of the core tube. An annular slide is slidably mounted coaxially in the annular groove, and an end face magnetic ring is coaxially embedded and fixed at the bottom end of the slide. Several drive columns perpendicular to the slide are rotatably mounted on the top end face of the slide groove. The bottom end of the drive column is rotatably mounted in the top end face of the slide groove, and the top end is mounted in the central mounting groove inside the upper flange plate and coaxially fixed with a driven gear. The part between the two ends of the drive column is threaded through the bottom of the mounting groove and enters the annular groove. A drive gear is rotatably mounted coaxially in the central mounting groove. The drive gear meshes with several driven gears surrounding it so that when the drive gear rotates, all drive columns rotate synchronously and push the slide to move axially.

[0008] Furthermore, a cylindrical stepped transmission protrusion is coaxially rotatably installed in the central mounting slot. The transmission protrusion rotates synchronously with the drive gear plate via a key connection. The transmission protrusion has a stepped through hole in the axial direction. A locking plug is threaded into the upper section of the stepped through hole, and the lower section of the stepped through hole is a wrench hole that can be inserted and engaged with an internal hex wrench. When the locking plug is tightened, it can be fixed to the upper flange plate through a pressure plate that is coaxially covered on the top surface of the drive gear plate.

[0009] Furthermore, a locking bolt is coaxially rotatably installed inside the locking plug. The locking bolt is threadedly connected to the upper flange connecting plate. When the locking bolt is tightened, its bottom end axially presses against an adjusting rod located coaxially inside the core tube. The adjusting rod has several thread segments, each thread segment is fitted with a threaded ring, and a connecting rod is fixed radially to the threaded ring. The connecting rod slides through the slot in the side wall of the core tube and is fixed to a base coaxially sleeved on the core tube. The base is used to coaxially and fixedly embed the inner magnetic ring so that when the adjusting rod is rotated, all the inner magnetic rings can move synchronously along the axial direction of the core tube.

[0010] Furthermore, the groove in the base for mounting the inner magnetic ring is a rectangular groove, and a stud is fixed in the center of the back of the base. The stud is threadedly located inside the connecting rod, and both the connecting rod and the slot are rectangular shapes that allow them to slide vertically relative to each other.

[0011] Furthermore, the top center of the adjusting rod is provided with a hexagonal slot, which allows an internal hex wrench to be inserted. The bottom end of the adjusting rod has a positioning shoulder, which is in rotatable contact with the end face of the lower flange plate.

[0012] Furthermore, the diameters at both ends of the core tube and the sleeve are larger than the diameter between the two ends, so as to accommodate the flange plate and the end face magnetic ring respectively; a protective sleeve is coaxially fixed on the outer wall of the two flange plates near the screw holes, which is used to cover the gap formed at the ends between the sleeve and the flange plate.

[0013] Furthermore, the fan blades are rectangular plate-shaped structures, with five fan blades arranged in a ring array around the sheath.

[0014] Furthermore, it also includes several sets of photovoltaic power generation components installed on the side of the light pole. The photovoltaic power generation components include photovoltaic panel components and flexible solar cell films. The photovoltaic panel components include solar panels, two cantilever rods arranged vertically, and two support rods. The two cantilever rods are respectively horizontally fixed to the same side of the two flanges of the light pole. One end of the two support rods is hinged to the center of the back of the solar panel frame, and the other end is respectively hinged to a slider. The sliders are linearly slidably installed on the corresponding cantilever rods, and the sliders can be fixed on the cantilever rods after sliding into place. The flexible solar cell film covers the surface of the fan blades.

[0015] The beneficial effects of this invention are as follows: This new energy power generation device, installed on a light pole, employs a coaxial magnetic levitation structure, eliminating mechanical friction and significantly reducing start-up wind speed, enabling power generation even in light breezes and improving power generation efficiency and lifespan. Specifically, at least one end face magnetic ring is axially adjustable, allowing for a trade-off between adjusting levitation force based on wind strength, balancing flexible rotation in weak winds and stable operation in strong winds, thus best adapting to specific working environments.

[0016] Meanwhile, the present invention also adds an inner magnetic ring axial adjustment mechanism to precisely optimize the alignment of the inner and outer magnetic rings, adapt to different working conditions, and further improve power generation performance; the flange plate and the lamp post in the present invention can be detachably connected, supporting multi-level series installation, and can flexibly expand capacity to increase power generation.

[0017] In addition, this invention integrates wind power generation with flexible solar cell films and adjustable-angle photovoltaic panels to achieve wind-solar synergistic power generation, resulting in higher energy utilization.

The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] This invention provides a technical solution: a new energy power generation device installed on a light pole, which adopts a coaxial magnetic levitation wind power generation structure as the whole, and the core components are as follows: Figures 1-3As shown, the assembly includes a core tube 1, an inner magnetic ring 3, an outer magnetic ring 2, a sleeve 5, fan blades 6, and a flange plate. Specifically, multiple inner magnetic rings 3 are coaxially nested and fixed on the outer side of the core tube 1 along its own axis. The inner magnetic rings 3 can be neodymium iron boron strong magnetic rings, or, depending on the specific implementation, radially magnetized magnetic rings can be selected. Enamelled wire coils 4 are tightly wound and fixed on the outer wall of the core tube 1 between two adjacent inner magnetic rings 3. The coils 4 can be adapted to the winding principle of existing generators to ensure that the windings are connected to the external energy storage circuit and used to cut magnetic field lines to generate induced current. A thin-walled sleeve 5 is fitted over the outer side of the core tube 1. The inner wall of the sleeve 5 is not in contact with the outer wall of the core tube 1, and a uniform air gap is reserved to achieve non-contact fitting. Five rectangular fan blades 6 are integrally formed or welded to the outer wall of the sleeve 5. The fan blades 6 are evenly arranged around the circumference of the sleeve 5 and can drive the sleeve 5 to rotate synchronously when exposed to wind. The inner wall of the sleeve 5 is centrally located, with a fixed outer magnetic ring 2 embedded within it. The inner diameter of the outer magnetic ring 2 is larger than the outer diameter of the structure formed by the inner magnetic ring 3 and the coil 4, ensuring that all inner magnetic rings 3 and coils 4 are completely enclosed within the outer magnetic ring 2 and do not contact each other, forming a coaxial alignment of the inner and outer magnetic rings. Furthermore, flange plates must be coaxially interference-fitted or welded at both ends of the sleeve 5. Both flange plates have mounting screw holes that match the flange 29 on the lamp post 24, allowing for detachable fixing to the lamp post 24 body via bolts. This facilitates multi-stage series installation of the power generation device and increases power generation. On the end faces of the flange plate and the sleeve 5, a magnetic ring 8 is coaxially embedded in each end face. Each pair of magnetic rings repels each other. In specific manufacturing, at least one end, for example, the magnetic ring 8 at the upper flange plate is set as an axially adjustable structure, while the magnetic ring 8 at the lower flange plate is installed in a non-adjustable position. By adjusting the axial position of the upper magnetic ring 8, the magnetic force between the magnetic rings 8 is changed, so that the sleeve 5 forms a suspension state without mechanical friction outside the core tube 1. When the wind flows in from the space between the adjacent fan blades 6 and blows the fan blades 6, the sleeve 5 can drive the outer magnetic ring 2 to rotate freely around the core tube 1. The coil 4 continuously cuts the alternating magnetic field formed by the inner and outer magnetic rings 2 to complete wind power generation. The adjustment of the relative spacing of the magnetic rings allows the sleeve 5 to rotate more flexibly relative to the core tube 1, and it can also rotate to generate electricity even in weak winds. At the same time, the spacing can be appropriately reduced according to the specific wind field of the power generation environment, so that the sleeve 5 can rotate more stably in strong winds, thus making a compromise between power generation and power generation stability.

[0025] In this embodiment, as Figure 1 , Figure 3As shown, both ends of the core tube 1 are machined with circular sockets, which have positioning steps for socketing to ensure assembly accuracy. The flange plate faces the end face of the core tube 1 and has an integrally formed cylindrical stepped part. The outer diameter of the stepped part matches the inner diameter of the socket at the end of the core tube 1 for positioning. During assembly, the stepped part of the flange plate is coaxially inserted into the socket of the core tube 1 and fixed by welding, interference fit, or a number of fastening screws (not shown in the figure) evenly distributed around the circumference to avoid radial offset and axial movement between the flange plate and the core tube 1, and to ensure the stability and reliability of the sleeve 5 when it is suspended and rotates.

[0026] This embodiment focuses on the axial adjustment structure of the end face magnetic ring 8 of the upper flange plate 7: see below. Figure 1 and Figure 3 An annular groove is machined on the bottom surface of the upper flange plate 7 near its outer edge. The groove cross-section can be rectangular and coaxially corresponds to the end face magnetic ring 8 on the sleeve 5 so that the two end face magnetic rings 8 can be aligned. In order to install the end face magnetic ring 8, a similarly annular slide block 23 is coaxially nested in the annular groove. The outer wall of the slide block 23 slides against the inner wall of the groove and can slide up and down along the groove axis. An end face magnetic ring 8 is coaxially embedded and fixed inside the bottom end of the slide block 23. Six vertical drive columns 11 are rotatably installed in the bottom of the annular groove. The axis of the drive column 11 is parallel to the axis of the core tube 1, that is, perpendicular to the bottom of the groove. The bottom end of the drive column 11 is rotatably installed inside the top surface of the slide block 23 and will not detach. The top end extends into the central mounting groove 701 inside the upper flange plate 7 and is coaxially fixed to the driven gear 12. Furthermore, the middle section of the drive column 11 is machined with an external thread, which passes through the bottom of the central mounting groove 701 and engages with the drive screw hole 70101. Thus, when the driven gear 12 rotates, it causes the drive column 11 to rotate along the thread, allowing the drive column 11 to rotate while moving axially. This, in turn, drives the slide 23 to rise and fall axially, changing the installation position of the end face magnetic ring 8 within the upper flange plate 7. Specifically, in the manufacturing process, a large drive gear 13 is coaxially mounted within the central mounting groove 701. The drive gear 13 is an external gear, meshing with all six circumferentially distributed driven gears 12 to achieve single-power synchronous drive. This allows all drive columns 11 to move axially synchronously, thus synchronously pushing the end face magnetic ring 8. This prevents the end face magnetic ring 8 from getting stuck in the annular groove due to uneven force, or from being misaligned. For example, when the active gear disk 13 is rotated, the six drive columns 11 rotate synchronously in the same direction, and push the slide block 23 evenly to drive the upper end face magnetic ring 8 to move axially, accurately adjusting the magnetic force between the pair of end face magnetic rings 8 located at the top, adapting to the end face suspension gap requirements under different wind conditions.

[0027] In this embodiment, as Figure 3 As shown, combined with Figure 6A cylindrical stepped transmission protrusion 14 is coaxially mounted in the central mounting groove 701 of the upper flange plate 7. The transmission protrusion 14 is connected to the drive gear plate 13 via a key 15 to achieve synchronous rotation and prevent slippage. The axial mounting position of the end face magnetic ring 8 is adjusted by rotating the transmission protrusion 14. Specifically, the transmission protrusion 14 has a stepped through hole inside, with the upper section being an internally threaded hole, threaded to a... Figure 10 The locking plug 16 shown; the lower section of the transmission protrusion 14 is a hex wrench hole, with a diameter suitable for standard M6 hex wrenches, allowing the operator to easily insert the wrench to rotate the transmission protrusion 14, which in turn rotates the drive gear 13. For example... Figures 3-4 As shown, when the locking plug 16 is tightened, it presses down on the circular pressure plate 10 that coaxially covers the top surface of the drive gear 13. The pressure plate 10 presses the drive gear 13, thereby preventing the pressure plate 10 from rotating and ensuring the stable installation position of the end face magnetic ring 8 in the upper flange plate 7. This ensures that the fan blade 6 can operate flexibly and reliably and generate electricity under the set wind force level. In addition, the locking plug 16 also pulls and tightens the transmission protrusion 14, which then tightly presses against the upper flange plate 7, achieving the purpose of fixing the transmission protrusion 14. Thus, by tightening the drive gear 13 and fixing the transmission protrusion 14, the locking and fixing of the corresponding end face magnetic ring 8 after adjustment is achieved, improving the stability of the set magnetic levitation performance. When the locking plug 16 is loosened, the transmission protrusion 14 can be driven to rotate by the Allen wrench, thereby driving the drive gear 13 to complete the axial adjustment of the end face magnetic ring 8.

[0028] In this embodiment, an additional axial adjustment mechanism for the inner magnetic ring 3 is provided to perform appropriate synchronous fine-tuning of all the inner magnetic rings 3, ensuring that the inner magnetic ring 3 and the outer magnetic ring 2 are in the ideal relative position. Specifically, as follows: Figure 4 As shown, a device such as [example device] can be coaxially rotatably installed inside the aforementioned locking plug 16. Figure 11 The locking bolt 17 shown penetrates the stepped through hole of the locking plug 16 and the transmission protrusion 14, and is threadedly connected to the threaded mounting hole 702 inside the upper flange plate 7 to achieve the fixing of the locking bolt 17; when the locking bolt 17 is as shown Figure 4 When tightened as shown, its bottom end axially presses against an adjusting rod 18 coaxially arranged inside the core tube 1. Both ends of the adjusting rod 18 are rotatably engaged with the core tube 1. The outer wall of the adjusting rod 18 is machined with four equidistant external threads, each thread corresponding to a threaded ring 21. The inner wall of the threaded ring 21 engages with the thread of the adjusting rod 18. Figure 1 and Figure 3As shown, each threaded ring 21 is radially fixed with a connecting rod 19. The connecting rod 19 can be detachably connected to the threaded ring 21 for installation, or it can be directly welded. A corresponding axially extending slot 101 is formed on the side wall of the core tube 1. The end of the connecting rod 19 passing through the slot 101 is fixedly connected to an annular base 20 fitted on the core tube 1. The inner wall of the base 20 slides against the outer wall of the core tube 1 and maintains a certain relative fixed relationship under magnetic force. An inner magnetic ring 3 is coaxially embedded and fixed inside the base 20, allowing the inner magnetic ring 3 to move with the base 20 to adjust the installation position. When the adjusting rod 18 is rotated, each threaded ring 21 slides synchronously along the axial direction of the adjusting rod 18. Through the connecting rod 19, the base 20 and the inner magnetic ring 3 move synchronously along the axial direction of the core tube 1, precisely adjusting the axial alignment relationship between all inner magnetic rings 3 and outer magnetic rings 2, optimizing the flexibility of magnetic levitation installation, and adapting to power generation conditions under different wind speeds.

[0029] In this embodiment, the assembly structure of the base 20, inner magnetic ring 3, and connecting rod 19 is specifically described. In practice, the groove of the base 20 for installing the inner magnetic ring 3 can be set as a rectangular groove, and the groove size is precisely matched with the outer diameter and thickness of the inner magnetic ring 3. The base 20 can also be specifically manufactured as a split structure, that is, an L-shaped ring 2001 and a circular annular plate 2002, so that the inner magnetic ring 3 is first put on the ring 2001, and then the annular plate 2002 is fixed on. Specifically, it can be welded or threaded. In addition, as Figure 3 , Figure 5 Alternatively, a stud 22 can be integrally formed in the center of the back of the base 20, which engages with the internal threaded hole at the end of the connecting rod 19, enabling a detachable connection between the base 20 and the connecting rod 19, facilitating the maintenance and replacement of the inner magnetic ring 3. The slot 101 on the side wall of the core tube 1 and the cross-section of the connecting rod 19 are both rectangular, with minimal sliding clearance between them, allowing the connecting rod 19 to slide along the length of the slot 101, i.e., along the axis parallel to the core tube 1, ensuring that the inner magnetic ring 3 always maintains coaxiality with the core tube 1 when moving axially.

[0030] In this embodiment, for ease of adjustment, such as Figure 4 As shown, a hexagonal slot is machined in the center of the top end face of the adjusting rod 18. The slot size is adapted to a standard hex wrench. After removing the locking bolt 17, the operator can directly insert the wrench into the slot and rotate the adjusting rod 18 to achieve axial adjustment of the inner magnetic ring 3. The operation is convenient and does not require additional disassembly of other components. Near the bottom end of the adjusting rod 18, there is an integrally formed annular positioning shoulder. The outer diameter of the positioning shoulder is larger than the outer diameter of the main body of the adjusting rod 18. The end face of the shoulder rotates and fits in contact with the inner end face of the lower flange plate 9, forming an axial limiting structure, which not only restricts the axial movement of the adjusting rod 18, but also ensures the stability of the adjusting rod 18 when it rotates.

[0031] In this embodiment, as Figure 1 , Figure 3As shown, both the core tube 1 and the sleeve 5 adopt a variable diameter structure with a thinner middle section and thicker end sections. The larger diameter sections at both ends are used to assemble the flange plate and the end face magnetic ring 8, respectively. Especially when installing a larger magnetic ring, the two ends need to be designed to be slightly thicker, while the smaller diameter section in the middle is reserved with sufficient magnetic field space and rotation clearance to avoid component interference. The upper and lower flange plates are coaxially welded and fixed on the outer walls of the corresponding mounting bolt holes. Figure 3 The cylindrical protective sleeve 30 shown is made of stainless steel thin shell structure. Its length covers the end gap between the sleeve 5 and the flange plate, completely covering the suspension gap and the end face magnetic ring 8. This prevents rainwater, dust and insects from entering the interior and affecting the performance of the magnetic ring and the smoothness of rotation. It also prevents outdoor debris from jamming the rotation of the sleeve 5, while improving the overall aesthetics of the device and meeting the protection needs of the light pole 24 in outdoor scenarios.

[0032] In specific manufacturing, the fan blades 6 can be made of lightweight, high-strength ABS engineering plastic. A total of five fan blades 6 are set, with an overall rectangular plate structure that balances wind-receiving area and structural rigidity. The five fan blades 6 are evenly distributed in a ring array on the outer wall of the sleeve 5, with the included angle between adjacent fan blades 6 being 72°. When the sleeve 5 is also made of plastic, the root of the fan blades 6 can be integrally injection molded with the outer wall of the sleeve 5. The rectangular fan blades 6 have moderate wind resistance, which can drive the sleeve 5 to rotate in a light wind environment and will not produce violent shaking in a strong wind environment, ensuring the stability of the suspension and rotation. At the same time, it can also be adapted to the bonding and laying of flexible solar cell films mentioned below.

[0033] In this embodiment, based on the aforementioned series of wind power generation main structures, supporting photovoltaic power generation modules are added, specifically as follows: Figure 12 As shown, several sets of photovoltaic power generation modules can be installed on the side of the light pole 24. Each set of photovoltaic power generation modules includes a photovoltaic panel module and a flexible solar cell film. The photovoltaic panel module includes a monocrystalline silicon solar panel 25, two horizontal cantilever rods 26, and two V-shaped support rods that are obliquely hinged. The two cantilever rods 26 are respectively fixed on the same side of the two flanges 29 connected to the power generation device on the light pole 24, and the rod body extends horizontally along the radial direction of the light pole 24. A hinge seat is provided in the center of the back of the solar panel 25 frame. The two support rods include a first support rod 27 and a second support rod 28. One end of the two support rods is hinged to the hinge seat, and the other end is respectively hinged to the sliders on the cantilever rods 26. Each slider slides and nests on the outer wall of the cantilever rod 26 and can slide linearly along the rod body. After sliding into place, it can be locked and fixed by T-bolts, etc. By adjusting the position of the sliders, the solar panel 25 can be more easily fixed between the two cantilever rods 26. In addition, if the solar panel 25 is set to have an adjustable tilt angle, it can also be... Figure 12A tightening bolt 31 is added as shown, preferably installed through a strip-shaped screw hole. When the two support rods move the solar panel 25 to the corresponding tilt angle, the tightening bolt 31 is tightened to hold the solar panel 25 firmly in place on the upper and lower sides of the frame, thus allowing flexible adjustment of the tilt angle of the solar panel 25 and maximizing the reception of sunlight. Furthermore, based on the design of the fan blade 6, the flexible solar film used is made of ultra-thin flexible crystalline silicon material, tightly bonded to the front and back surfaces of each fan blade 6. While rotating synchronously with the fan blade 6, it continuously receives sunlight and generates electricity. The electricity generated from both sources is fed into the built-in energy storage controller of the light pole 24, achieving wind and solar power co-generation and improving the utilization rate of new energy sources.
