Description

Technical Field

[0001] This utility model belongs to the field of vertical axis wind power generation, and in particular, it is a self-powered highway wind and solar energy harvesting device. Background Technology

[0002] With the increasing global demand for renewable energy to address the energy crisis, reduce greenhouse gas emissions, and achieve sustainable development goals, wind power has been widely adopted as a clean and sustainable energy source. Wind power utilizes abundant natural wind energy resources, converting them into electricity to provide a continuous supply of green energy for human society.

[0003] Among the many wind power generation technologies, vertical axis wind turbines have advantages such as simple structure, no need for wind-fighting devices, and low noise. These characteristics enable vertical axis wind turbines to exhibit good adaptability in a variety of environments, especially in situations where space is limited or low-noise operation is required, such as highway areas where they have great application potential.

[0004] Highways, as a crucial component of modern transportation networks, not only experience high traffic volume and heavy traffic, but also often possess relatively open and stable wind energy resources along their routes. Applying vertical axis wind turbines to highway areas can effectively utilize these idle wind energy resources, providing power for highway lighting, monitoring systems, and nearby charging stations, reducing reliance on the traditional power grid. Furthermore, it can lower operating costs to some extent and enhance the intelligence and greening level of highways.

[0005] However, existing vertical axis wind turbines still have room for improvement in terms of energy harvesting efficiency and versatility. On the one hand, due to the relatively complex aerodynamic characteristics of vertical axis wind turbines, how to further improve their energy conversion efficiency and reduce wind energy loss while maintaining their structural simplicity is a key challenge. On the other hand, with the increasingly diversified demands for green energy utilization, how to equip vertical axis wind turbines with more additional functions to form integrated comprehensive energy solutions is also an important direction for future development. Summary of the Invention

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A self-powered highway wind and solar energy harvesting device, characterized in that it includes a solar panel, an upper base, a main shaft, blades, an electromagnetic generator, a lower base, a storage system, and a sensor unit.

[0009] The solar panel is mounted on the top of the upper base. The two ends of the main shaft are rotatably connected to the upper base and the lower base, respectively. The main shaft is a hollow shaft. Several blades are mounted on the main shaft circumferentially. Triboelectric nanogenerators are provided on the blades.

The solar panel, the electromagnetic generator, and the triboelectric nanogenerator are all connected to the storage system. The storage system is connected to the sensor unit.

[0010] Furthermore, a guide plate is provided on the periphery of the blade, and the two ends of the guide plate are respectively fixedly connected to the upper base and the lower base.

[0013] Furthermore, the rotating shaft of the electromagnetic generator is installed at the central axis of the housing, the rotating shaft is fixedly connected to the main shaft, and a coil is fixed on the rotating shaft.

[0014] Furthermore, the triboelectric nanogenerator includes a triboelectric layer, an electrode layer, and an adhesive layer. The triboelectric layer and the electrode layer are respectively bonded to both sides of the adhesive layer to form a "sandwich" structure. The electrode layer is bonded to both sides of the blade surface.

[0015] Furthermore, the storage system includes a lithium battery connected to a solar panel via a solar panel output wire, a lithium battery connected to the wiring terminal of an electromagnetic generator via an electromagnetic generator output wire, and a lithium battery connected to the current collector assembly of a triboelectric nanogenerator via a triboelectric nanogenerator output wire.

[0016] Furthermore, rectifiers and filters are provided on the output wires of the solar panel, the electromagnetic generator, and the triboelectric nanogenerator.

[0017] Furthermore, the current collector assembly includes a current collector ring, which is installed inside one end of the main shaft. The current collector ring is electrically connected to the brush, which is fixed to the brush holder by a spring. The current collector ring is connected to the electrode layer of the triboelectric nanogenerator via copper wire, and the brush is connected to the output wire of the triboelectric nanogenerator via copper wire.

[0018] Furthermore, the sensor unit includes a wind speed sensor, a wind direction sensor, a temperature sensor, and a vibration sensor.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention provides a self-powered highway wind and solar energy harvesting device. A solar panel is mounted on top of an upper base, with the upper and lower bases rotatably connected to the two ends of a main shaft. Several blades are circumferentially mounted on the main shaft, and an electromagnetic generator is mounted on the lower base and connected to the main shaft. Triboelectric nanogenerators are installed on the blades. This achieves comprehensive utilization of wind and solar energy, enabling continuous power generation under various weather conditions. In windy but weak sunlight conditions, wind power and triboelectric nanogenerators are the primary sources of power; in sunny but weak conditions, solar power plays a major role. This complementarity fully utilizes the wind and solar energy resources of the highway area, significantly improving energy harvesting efficiency compared to single-energy harvesting methods. This invention utilizes vertical axis wind power technology, making it suitable for various wind directions and adaptable to the complex airflow environment of highways. The solar panels and triboelectric nanogenerator materials also function effectively under different weather conditions, giving the overall device strong environmental adaptability. It efficiently harvests wind and solar energy from the highway area, and the addition of triboelectric nanogenerator materials further enhances energy harvesting efficiency. The electrical energy collected by solar panels, electromagnetic generators, and triboelectric nanogenerators is stored in a shared storage system, which then powers sensor units and roadside facilities. This achieves self-powering, reduces dependence on the external power grid, lowers energy supply costs, and provides stable energy support for highway infrastructure. This invention utilizes renewable wind and solar energy for power generation, reducing reliance on traditional fossil fuels and lowering greenhouse gas emissions, thus meeting environmental protection and sustainable development requirements. Furthermore, triboelectric nanogenerator technology, as a novel energy harvesting technology, offers advantages such as being pollution-free and noise-free, further enhancing the device's environmental performance.

[0021] Furthermore, by using sensor units to monitor parameters such as wind speed, wind direction, temperature, and vibration in real time, abnormal conditions of the equipment, such as overheating and mechanical failures, can be detected in a timely manner. The early warning system can then notify maintenance personnel in advance to handle these issues, thus avoiding energy collection interruptions caused by equipment damage. This improves the reliability and stability of the device and reduces maintenance costs and downtime. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present 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.

[0035] 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.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings:

[0040] See Figure 1 This utility model provides a self-powered highway wind and solar energy harvesting device, including a solar panel 1, an upper base 2, a guide plate 3, a main shaft 4, blades 5, an electromagnetic generator 6, a lower base 7, a triboelectric nanogenerator 15, and related harvesting circuits, storage systems, and sensor units.

[0041] Solar panel 1 is installed on top of upper base 2. Solar panel 1 is made of high-efficiency photovoltaic materials and can convert solar energy into electrical energy. The surface of solar panel 1 is coated to enhance its UV resistance and durability. Meanwhile, in practical applications, the installation angle of solar panel 1 should be appropriately adjusted according to the geographical location to ensure it receives maximum sunlight, thereby improving the solar energy conversion efficiency.

[0042] The main shaft 4 is rotatably mounted vertically on the central axis of the upper base 2 and the lower base 7, and is connected to the upper base 2 and the lower base 7. The upper base 2 and the lower base 7 are respectively installed at the top and bottom of the main shaft 4, and their central axes coincide. This is used to transfer the kinetic energy of the blades 5 to the electromagnetic generator 6. To save materials and provide space for wiring, the main shaft 4 is designed as a hollow cylindrical structure. The upper base 2, the main shaft 4, and the lower base 7 work together to form a solid and reliable foundation for the operation of the device. It should be mentioned that the upper base 2 and the lower base 7 also act as a kind of "cap," which prevents the airflow in the concave surface from diffusing from both ends, increases the pressure on all four sides, increases the positive torque of the blades 5, and thus improves the wind energy utilization rate.

[0043] like Figure 2 As shown, several blades 5 are mounted circumferentially on the main shaft 4. In order to adapt to the airflow characteristics of the highway area and improve the wind energy capture efficiency and wind energy conversion efficiency, the blades 5 are made of lightweight and high-strength composite materials, and the shape of the blades 5 is elliptical.

[0044] like Figure 4 As shown, the electromagnetic generator 6 includes a housing 8, a rotating shaft 10, a permanent magnet 9, and a coil 11. The central axis of the housing 8 coincides with the central axis of the main shaft 4, and the housing 8 is mounted on the lower base 7 to protect the internal structure of the electromagnetic generator 6 and ensure that the electromagnetic generator 6 has sufficient conditions for normal operation. The permanent magnet 9 is mounted on the inner wall of the housing 8 to provide a constant magnetic field. The rotating shaft 10 is mounted at the central axis of the housing 8 and connected to the main shaft 4. The coil 11 is fixed on the rotating shaft 10 and rotates with the rotating shaft 10.

[0045] The triboelectric nanogenerator 15 is bonded to corresponding locations on both sides of the blade 5 using a high-strength adhesive, as shown in the example below. Figure 7 As shown, when blade 5 rotates under the action of wind, the triboelectric nanogenerator 15 generates electricity through friction with the air. Considering the factors related to power generation efficiency and economic cost, the triboelectric nanogenerator 15 is mainly positioned at the leading edge of the blade, where the airflow velocity is high and the friction with the air is more significant, thus generating a larger amount of charge.

[0046] like Figure 5 As shown, the triboelectric nanogenerator 15 includes a triboelectric layer 12, an electrode layer 14, and an adhesive layer 13. The triboelectric layer 12 is made from a commercially available polytetrafluoroethylene (PTFE) film cut to the required size. The electrode layer 14 is made from copper strips of the same size as the film. The adhesive layer 13 is made from a commonly used conductive adhesive—silver paste—used to firmly bond the copper electrodes to the back of the PTFE film. The triboelectric layer 12 and the electrode layer 14 are respectively bonded to both sides of the adhesive layer 13, forming a "sandwich" structure, and are bonded to the surface of the blade 5 through the electrode layer 14. This "sandwich" structure of the triboelectric nanogenerator 15 ensures that the charge generated by the triboelectric layer 12 can enter the electrode layer 14 through the shortest possible path, thereby improving power generation efficiency.

[0047] In the highway area, when the incoming airflow generated by vehicles blows towards blade 5 at a certain speed, it generates a positive torque on the concave surface of blade 5, pushing blade 5 to rotate clockwise, and a negative torque on the convex surface of blade 5, inhibiting its clockwise rotation. Therefore, a guide vane 3 is installed around blade 5, and the relative positions of blade 5 and guide vane 3 are as follows: Figure 3 As shown. The deflector 3 reduces the negative torque generated when the blade 5 rotates leeward, and directs the airflow as far as possible towards the windward blade 5 area, making it more effective in driving the windward blade 5 and improving the wind energy utilization rate of wind power generation. At the same time, the deflector 3 also has other multiple functions. First, it improves the power generation efficiency of the triboelectric nanogenerator 15 by accelerating the airflow velocity. Second, it can block foreign objects and prevent damage to the blade 5. Considering the torque generated by the wind on the deflector 3, in the vertical direction, the deflector 3 is also fixedly installed between the upper base 2 and the lower base 7, and connected to the upper base 2 and the lower base 7 to form a whole, improving the stability of the device in the wind and preventing the deflector 3 from losing its function due to insufficient bending strength.

[0048] like Figure 8 As shown, each of the triboelectric nanogenerator, wind power generation, and solar power generation is equipped with an independent energy collection circuit. The collection circuit includes a solar panel output wire 22, an electromagnetic generator output wire 23, and a triboelectric nanogenerator output wire 24, each equipped with a rectifier and a filter.

[0049] The solar panel 1 is located on the upper base 2 of the device. The solar panel output wire 22 is led out from the back of the solar panel 1. After being led out, the solar panel output wire 22 is laid along the surface of the upper base 2, passing through the outside of the guide plate 3 towards the lithium battery 21. The electromagnetic generator 6 is located on the lower base 7. The electromagnetic generator output wire 23 is led out from the inside of the electromagnetic generator housing 8, with the lead-out point being the wiring hole reserved on the housing 8. After exiting from the wiring hole, the electromagnetic generator output wire 23 is arranged along the surface of the lower base 7 towards the lithium battery 21.

[0050] Since the triboelectric nanogenerator 15 is mounted on the rotating blade 5, directly extending a wire is obviously not feasible. This invention incorporates a current collector assembly in the hollow part of the main shaft 4 to prevent damage to the wire due to direct twisting. The structure of the current collector assembly is shown in the diagram below. Figure 9 As shown, the current collector assembly is installed in the hollow part at the lower part of the main shaft 4. The current collector ring 16 is installed on the inner wall of the main shaft 4 and rotates synchronously with the main shaft 4, facilitating disassembly and replacement. The current collector ring 16 is made of copper alloy with good conductivity and consists of multiple mutually insulated annular conductive tracks, each track corresponding to a wire. Adjacent annular conductive tracks are separated by high-performance plastic, with an insulation material thickness of 2mm to prevent short circuits between different tracks. The brush 17 is fixed to the brush holder 18 by springs 20. The shape of the brush 17 is designed to be rectangular, and its size matches the annular conductive tracks of the current collector ring 16. The brush 17 and the annular conductive tracks are provided with appropriate pressure by the springs 20 to ensure good electrical contact without causing excessive wear due to excessive pressure. The current collector ring 16 is connected to the electrode layer 14 of the triboelectric nanogenerator 15 through copper wires 19, and each brush 17 is connected to the output wire 24 of the triboelectric nanogenerator through copper wires 19.

[0051] As the copper wire 19 on the triboelectric nanogenerator 15 rotates with the blade 5, it connects to the corresponding annular conductive track on the collector ring 16. The collector ring 16 rotates synchronously with the main shaft 4, while the brush 17 remains stationary. Thus, through the sliding contact between the brush 17 and the collector ring 16, electrical energy transfer between the rotating wire and the circuit system is achieved. During this process, the brush 17 adapts to the rotation of the collector ring 16, maintaining a good electrical connection with the annular conductive track, stably transmitting electrical energy and signals from the wire to the storage system, while preventing damage to the wire due to direct twisting.

[0052] This invention adds a sensor unit to the above-mentioned structural configuration, employing multiple sensors to monitor the operating status of the equipment, provide early warning of equipment malfunctions, and collect relevant data. Wind speed and direction sensors are mounted on the guide plate 3 for real-time monitoring of wind speed and direction. Temperature sensors are installed in the electromagnetic generator 6, solar panel 1, and storage system to monitor the operating temperature of the equipment and prevent overheating damage. A vibration sensor is mounted on the main shaft 4 to monitor the vibration of the equipment and promptly detect potential mechanical faults. The relevant wiring for the sensor unit is generally laid alongside existing wiring. The input wires for the temperature sensor at the solar panel 1 and the wind speed and direction sensors on the guide plate 3 are laid alongside the output wire 22 of the solar panel; the input wires for the temperature sensor at the electromagnetic generator 6 and the vibration sensor on the main shaft 4 are laid alongside the output wire 23 of the electromagnetic generator. This not only saves installation costs and avoids wire tangling but also makes the device more aesthetically pleasing.

[0053] This invention can be installed within the central median strip, utilizing the convective wind energy from both sides to generate electricity. Considering the wind energy generated when vehicles travel at high speeds on highways, the strongest winds occur around the vehicle body, and the height at which the wind force is generated decreases with increasing distance from the vehicle body. Therefore, the installation height of the device does not need to be too high; it is sufficient to utilize most of the convective wind energy. Considering the height of the median strip, the device's height above the ground is approximately 0.7m.

[0054] The working principle of this self-powered highway wind and solar energy harvesting device is as follows:

[0055] When sunlight shines on solar panel 1, it absorbs the light energy and generates electron-hole pairs. Under the influence of the electric field of the battery inside solar panel 1, the electrons and holes are separated and move to the two ends of the battery respectively, thus forming current and voltage.

[0056] For the electromagnetic generator 6, the incoming airflow generated by the vehicle drives the blades 5 to rotate. The blades 5 transmit kinetic energy to the rotating shaft 10 through the main shaft 4 and make it rotate. The rotating shaft 10 then drives the coil 11 to rotate. The rotating coil 10 cuts the magnetic field lines of the permanent magnet 9 and outputs electrical energy.

[0057] For the triboelectric nanogenerator 15, such as Figure 6The diagram illustrates the power generation principle of the triboelectric nanogenerator 15. Polytetrafluoroethylene (PTFE) film is a highly electronegative material with very low surface energy. When it comes into contact with air and undergoes relative motion, the PTFE surface adsorbs charged particles from the air and rubs against gas molecules, causing electrons to transfer from air molecules or other impurity particles to the PTFE surface, thus charging the PTFE surface. After the PTFE becomes charged through friction with the air, an equal amount of opposite charge is induced on the electrodes due to electrostatic induction, creating a potential difference between the electrodes. If the electrodes are connected to an external circuit via wires, charge will flow, thereby generating electricity. Because copper has good electrical and thermal conductivity, relatively low cost, and high conductivity, it can effectively transfer the charge generated by friction, reducing energy loss during transmission. Therefore, in this invention, copper is made into a thin sheet as the electrode layer 14 to adapt to the shape of the blade 5 and the power generation requirements.

[0058] The collected electrical energy is rectified and filtered by the collection circuit and then stored in the lithium battery 21 in the common storage system. The storage system then provides the necessary power to the sensor unit and roadside facilities.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
