It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described here can be implemented in an order other than those illustrated or described here.

[0035] The embodiment of the present utility model provides a wind-solar power generation device. Figure 1 It is a schematic structural diagram of a wind-solar power generation device provided by an embodiment of the present utility model. Figure 2 It is a schematic structural diagram of a wind-solar power generation module provided by an embodiment of the present utility model. Combining Figure 1 and Figure 2 , the device includes: a wind-solar power generation module 1, a circuit switching module 2, a voltage monitoring module 3, and an energy storage module 4. The wind-solar power generation module 1 includes a wind power generation unit 11 and a photovoltaic power generation unit 12. The photovoltaic power generation unit 12 is arranged on one side of the wind power generation unit 11; the wind power generation output end of the wind power generation unit 11 is electrically connected to the circuit switching module; the photovoltaic power generation output end of the photovoltaic power generation unit 12 is electrically connected to the circuit switching module. The circuit switching module 2 is further configured to be electrically connected to the highway power grid 5, and the circuit switching module 2 is used to supply power to the highway power grid 5. The voltage monitoring module 3 is connected to the power supply output end of the wind-solar power generation device; the voltage monitoring module 3 is used to detect the electrical parameters of the highway power grid 5. The circuit switching module 2 is also electrically connected to the energy storage module 4; the energy storage module 4 is also connected to the power supply output end of the wind-solar power generation device. The circuit switching module 2 is also electrically connected to the voltage monitoring module 3. The circuit switching module 2 is used to obtain electrical parameters and, according to the electrical parameters, input the electric energy generated by the wind-solar power generation module 1 into the energy storage module 4 and / or the highway power grid 5.
[0036] The wind-solar power generation module 1 is an integrated structure consisting of a wind power generation unit 11 and a photovoltaic power generation unit 12. For example, the wind power generation unit 11 may include a vertical bidirectional wind rotor assembly equipped with multiple elongated blades 112. The wide sides of the elongated blades 112 are narrow, and the long sides of the elongated blades 112 are perpendicular to the ground, resulting in a compact footprint for the vertical bidirectional wind rotor assembly. The photovoltaic power generation unit 12 can be mounted on top of the wind power generation unit 11, without needing to be staggered with the wind power generation units 11. The photovoltaic power generation unit 12 mounted directly on top of the wind power generation unit 11 is fully exposed to sunlight for solar power generation. When cars travel on the highway, the generated wind force drives the multiple elongated blades 112 of the vertical bidirectional wind rotor assembly to rotate. The wind power generation unit 11 generates wind power using the mechanical energy generated by the rotation of the elongated blades 112. The wind-solar power generation modules 1 are arranged at regular intervals along the highway. By increasing the number of wind-solar power generation modules 1, the power generation capacity can be continuously increased. The voltage monitoring module 3 can detect the electrical parameters of the highway power grid 5 in real time and input them into the circuit switching module 2. For example, the electrical parameters can be the voltage information of the highway power grid 5. When the voltage of the highway power grid 5 is lower than the rated voltage of the highway power grid 5, it indicates that the power consumption is at its peak. At this time, the circuit switching module 2 inputs all the power output by the wind and solar power generation module 1 into the highway power grid 5 for energy replenishment. If the power output of the wind and solar power generation device still cannot meet the power supply requirements of the electrical equipment, energy storage module 4 can also be used for energy replenishment. If the partial power output of the wind and solar power generation module 1 is sufficient to bring the voltage of the highway power grid 5 to its rated voltage, the circuit switching module 2 inputs the remaining power into the energy storage module 4 for storage. When the voltage of the highway power grid 5 is greater than or equal to the rated voltage of the highway power grid 5, it indicates that the power consumption is at its low point. The circuit switching module 2 inputs all the power output by the wind and solar power generation module 1 into the energy storage module 4 for storage, thus achieving a reasonable distribution of power in the highway power grid 5.
[0037] The technical solution provided by the present embodiment utilizes both solar and wind energy through the installation of a wind-solar power generation module 1, while its integrated structure reduces floor space. Furthermore, a voltage monitoring module 3 detects the electrical parameters of the highway power grid 5, and a circuit switching module 2 distributes the electrical energy. During peak periods, the highway power grid 5 is replenished, while during off-peak periods, the energy storage module 4 stores the energy. This integration of power generation, peak regulation, and energy storage achieves optimal utilization of electrical energy, ensuring that even during peak periods, the highway power grid 5's output can still meet the power requirements of electrical devices.
[0038] On the basis of the above embodiments, optionally, the power supply output end of the wind-solar power generation device is used to be electrically connected to a charging pile.
[0039] For example, charging piles include those found in highway service areas, which are often equipped with high-power charging piles. Charging electric vehicles with these high-power charging piles can significantly reduce charging time. However, during peak hours, the power provided by the highway grid 5 cannot meet the power requirements of the high-power charging piles, resulting in reduced charging pile power and longer charging times. By installing a wind and solar power generation device, the power generated by the wind and solar power generation module 1 can be fed into the highway grid 5, increasing the power supply capacity of the highway grid 5 to meet the power requirements of the high-power charging piles and improving the power supply to the charging piles during peak hours.
[0040] Figure 3 This is a schematic diagram of the structure of another wind-solar power generation device provided by an embodiment of the present utility model. Figure 3 Based on the above embodiments, the wind-solar power generation device optionally further includes a rectifier and filter unit 6. The wind power generation output terminal of the wind power generation unit 11 is electrically connected to the input terminal of the rectifier and filter unit 6. The photovoltaic power generation output terminal of the photovoltaic power generation unit 12 is electrically connected to the output terminal of the rectifier and filter unit 6; the output terminal of the rectifier and filter unit 6 is also electrically connected to the circuit switching module 2. The rectifier and filter unit 6 is used to rectify the AC power outputted by the wind power generation output terminal into DC power.
[0041] The electrical energy output by the wind power generation unit 11 is AC. However, because wind power generation is significantly affected by the environment and the wind blowing into the vertical bidirectional wind rotor assembly constantly changes, the AC power output by the wind power generation unit 11 is unstable. By providing a rectifier and filter unit 6, the unstable AC power output by the wind power generation unit 11 can be rectified into stable DC power and input into the circuit switching module 2. This configuration improves the power supply stability of the wind-solar power generation device. Furthermore, the electrical energy output by the photovoltaic power generation unit 12 is DC power. Therefore, the electrical energy output by the wind power generation unit 11 and the photovoltaic power generation unit 12 should be consistent. For example, the highway power grid 5 can be a DC power grid, and the wind power generation unit 11 and the photovoltaic power generation unit 12 jointly supply power to the DC power grid. Furthermore, the energy storage module 4 also requires DC power. With this configuration, there is no need to provide a separate rectifier and filter unit 6 for the energy storage module 4, simplifying the circuit structure.
[0042] Continue to refer Figure 2 Based on the above embodiments, the wind turbine generator unit 11 optionally includes a vertical bidirectional rotor assembly, which is provided with a plurality of elongated blades 112. The vertical bidirectional rotor assembly further includes a rotating shaft 111, an upper support assembly, and a lower support assembly. The rotating shaft 111 extends between the upper and lower support assemblies. One side of the plurality of elongated blades 112 is fixedly connected to the rotating shaft 111.
[0043] The rotating shaft 111 connects the upper and lower support assemblies of the vertical bidirectional wind rotor assembly and secures a plurality of elongated blades 112 within the vertical bidirectional wind rotor assembly. When the vertical bidirectional wind rotor assembly is exposed to wind, the plurality of elongated blades 112 drive the rotating shaft 111 to rotate, causing the wind power generation unit 11 to generate electricity.
[0044] Continue to refer Figure 2 Based on the above embodiments, the lower support assembly optionally includes a wind turbine assembly 113. Wind turbine assembly 113 is disposed at the bottom of the vertical bidirectional wind rotor assembly and connected to the vertical bidirectional wind rotor assembly's rotating shaft 111. Wind turbine assembly 113 is used to convert the mechanical energy generated by the rotation of the plurality of elongated blades 112 into electrical energy.
[0045] For example, the wind turbine generator assembly 113 may be a generator, which is a working device of the entire wind power generation unit 11. By providing a generator, the mechanical energy generated by the rotation of the shaft 111 driven by the long blades 112 can be converted into electrical energy.
[0046] Continue to refer Figure 2 Based on the above embodiments, optionally, the long strip blades 112 have an arc-shaped structure.
[0047] Among them, the use of an arc-shaped structure design can better ensure that the surface of the long blades 112 is subjected to wind force, thereby improving the kinetic energy conversion effect of the long blades 112, making it easier for the long blades 112 to be driven by the wind to rotate and do work. In addition, the use of an arc-shaped structure for the long blades 112 can further reduce the overall width of the vertical bidirectional wind wheel assembly and reduce the floor space of the vertical bidirectional wind wheel assembly. It makes it easier to install at the middle guardrail of the highway and takes up less floor space. The lane close to the middle guardrail of the highway is the fast lane, and the cars traveling at a higher speed, and the wind energy generated by the cars traveling on both sides of the middle guardrail can drive the rotation of the long blades 112, thereby increasing the power generation of the wind power generation unit 11.
[0048] Figure 4 This is a front view of the structure of a wind-solar power generation module provided by an embodiment of the utility model. Figure 2 and Figure 4 Based on the above embodiments, optionally, the photovoltaic power generation unit 12 includes a solar panel assembly 121. The solar panel assembly 121 is disposed above the vertical bidirectional wind wheel assembly and is electrically connected to the photovoltaic power generation output terminal.
[0049] Exemplarily, the solar panel assembly 121 can be a solar panel, which is a photovoltaic semiconductor thin film that directly generates electricity using sunlight. As long as it is illuminated by light with a certain illumination intensity, it can instantaneously output voltage and generate current in a loop. The electric energy generated by the solar panel assembly 121 can be input into the circuit switching module 2 through the photovoltaic power generation output terminal.
[0050] Figure 5 This is a schematic structural diagram of another wind-solar power generation device provided by an embodiment of the present invention. Refer to Figure 5 , on the basis of the above embodiments, optionally, the wind-solar power generation device further includes: an inverter 7. The circuit switching module 2 is electrically connected to the inverter 7, and the inverter 7 is configured to be electrically connected to the highway power grid 5; the inverter 7 is used to invert the direct current input by the circuit switching module 2 into alternating current and input it into the highway power grid 5.
[0051] Among them, the inverter 7 is a converter that converts direct current electrical energy into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated alternating current, and can adjust the voltage and frequency according to the electrical parameters of the highway power grid 5, so that the wind-solar power generation device provided by the embodiment of the present invention is also applicable to the alternating current power grid, expanding the scope of application. By setting the inverter 7, the electrical energy input from the circuit switching module 2 to the highway power grid 5 can be converted into alternating current adapted to the power grid, improving the stability during grid connection.
[0052] The embodiment of the present invention also provides a wind-solar power generation system, which includes the highway power grid 5 and the wind-solar power generation device provided by any embodiment of the present invention.
[0053] Among them, the wind-solar power generation device can be used to detect the electrical parameters input by the highway power grid 5 to the charging pile and perform power distribution according to the electrical parameters. When the electrical energy input by the highway power grid 5 to the charging pile does not meet the maximum charging power of the charging pile, the wind-solar power generation device on the highway generates electricity through the wind-solar power generation module 1 and inputs it into the highway power grid 5 to increase the power generation of the highway power grid 5, so that the charging power of the charging pile can be maintained at a stable state of high power. When the electrical energy input by the highway power grid 5 to the charging pile meets the maximum operating power of the charging pile, the wind-solar power generation device on the highway can input the electricity generated by the wind-solar power generation module 1 into the energy storage module 4 for energy storage.
[0054] On the basis of the above embodiments, optionally, the wind-solar power generation device is arranged inside the middle guardrail of the road and / or on both sides of the road.
[0055] The lanes near the central guardrail are express lanes, where cars travel at higher speeds. The wind energy generated by cars on both sides of the central guardrail provides a continuous supply of wind energy to wind power generation unit 11, unrestricted by climatic and geographical conditions. Furthermore, the central guardrail on the highway offers no shadows, providing a stable supply of sunlight to photovoltaic power generation unit 12, resulting in high power generation efficiency. Wind and solar power generation devices can also be installed on both sides of the highway. This arrangement increases the number of wind and solar power generation devices and maximizes power generation.
[0056] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this utility model can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of this utility model can be achieved. This is not limited herein.

Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors.
