Description

Technical Field

[0001] This utility model belongs to the field of power supply technology for rail vehicles, and in particular relates to a power supply system for rail vehicles based on wind-solar hybrid power supply. Background Technology

[0002] With economic development and population growth, traffic congestion in large cities is becoming increasingly severe. The growth of motor vehicles far exceeds the expansion of road area, making the construction of subways or light rails a fundamental solution to public transportation problems in many large cities. Traditional subways or light rails use overhead contact lines or contact rails for power supply, drawing electricity from the city's power grid. However, this single power supply method is extremely energy-intensive. With the development of new energy technologies, applying these technologies to the power supply of rail transit vehicles can effectively reduce energy consumption. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a rail vehicle power supply system based on wind and solar complementary power generation, which uses wind power generation and photovoltaic power generation to provide power to rail vehicles.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A power supply system for rail vehicles based on wind-solar hybrid power generation includes photovoltaic modules, wind turbine modules, energy storage batteries, and a control device. The photovoltaic modules and wind turbine modules are electrically connected to the control device, and the control device is electrically connected to the energy storage battery. The photovoltaic modules are installed on the roof of the vehicle and are used to convert light energy into electrical energy using the photovoltaic effect of solar panels, which then charges the energy storage battery. The wind turbine modules are installed on both sides of the vehicle and are used to convert wind energy into mechanical energy, which is then converted into electrical energy by a generator, and finally charged the energy storage battery to supply power to the load.

[0006] Furthermore, the wind turbine assembly includes a rotating shaft, a transmission mechanism, and a generator. The rotating shaft has a circular base at its bottom and a circular top plate above it. Six blades are evenly distributed on the rotating shaft. The rotating shaft is connected to the input end of the generator through the transmission mechanism. A wind deflector is also provided on the outer periphery of the blades, and the wind deflector covers at least part of the blades.

[0007] Furthermore, the blade is in the shape of a flat plate or an arc.

[0008] Furthermore, the control device includes a photovoltaic power generation controller and a wind power generation controller. The output end of the photovoltaic module is connected to the photovoltaic power generation controller, and the output end of the wind turbine module is connected to the wind power generation controller. The photovoltaic power generation controller and the wind power generation controller are respectively connected to a DC load and an energy storage battery. The energy storage battery is connected to an AC load through an inverter.

[0009] Furthermore, both the photovoltaic power generation controller and the wind power generation controller are microcontrollers.

[0010] Compared with existing technologies, the rail vehicle power supply system based on wind-solar hybrid power supply described in this utility model has the following advantages:

[0011] This invention utilizes wind power and photovoltaic power generation to provide electricity for rail vehicles, which can reduce energy consumption. At the same time, the equipment is simple, easy to install, and reliable in operation. Attached Figure Description

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-2 As shown, this utility model provides a rail vehicle power supply system based on wind-solar hybrid power, including a photovoltaic module 1, a wind turbine module 2, an energy storage battery 3, and a control device 4. The photovoltaic module 1 and the wind turbine module 2 are electrically connected to the control device 4, and the control device 4 is electrically connected to the energy storage battery 3. The photovoltaic module 1 is installed on the top of the carriage 5 and is used to convert light energy into electrical energy using the photovoltaic effect of the solar panels, and then charge the energy storage battery 3. The wind turbine module 2 is installed on both sides of the carriage 5 and is used to convert wind energy into mechanical energy, which is then converted into electrical energy by a generator, and then charged to the energy storage battery 3, which is used to supply power to the load.

[0023] like Figure 3As shown, the wind turbine assembly 2 includes a rotating shaft 21, a transmission mechanism 27, and a generator 22. The rotating shaft 21 has a circular base 23 at its bottom and a circular top plate 24 on its top. Six blades 26 are evenly distributed on the rotating shaft 21. The rotating shaft 21 is connected to the input end of the generator 22 via the transmission mechanism 27. A wind deflector 25 is also provided around the outer periphery of each blade 26, at least partially covering the blades 26. When the wind turbine assembly 2 is working, the wind on one side of the wind deflector 25 passes around the outside of the wind deflector 25 without generating thrust on the blades 26, while the other side receives the thrust of the wind, causing the blades 26 to rotate and generate mechanical energy. The generator 22 converts this mechanical energy into electrical energy. The generator 22 used in this invention is a wind turbine generator.

[0024] Specifically, the blade 26 is in the shape of a flat plate or an arc.

[0025] Specifically, the control device 4 includes a photovoltaic power generation controller 41 and a wind power generation controller 42. The output end of the photovoltaic module 1 is connected to the photovoltaic power generation controller 41, and the output end of the wind turbine module 2 is connected to the wind power generation controller 42. The photovoltaic power generation controller 41 and the wind power generation controller 42 are respectively connected to the DC load 7 and the energy storage battery 3. The energy storage battery 3 is connected to the AC load 8 through the inverter 6.

[0026] Specifically, both the photovoltaic power generation controller 41 and the wind power generation controller 42 are single-chip microcomputers.

[0027] This invention can be applied to vehicles operating on the ground and underground. Photovoltaic modules are installed above the vehicle body, and wind turbines are installed on both sides of the vehicle body. Control devices and energy storage batteries can be installed inside the vehicle body. When the vehicle is on the ground, the photovoltaic modules convert solar energy into electrical energy. A photovoltaic power generation controller connects to DC loads and the energy storage battery, directly supplying power to DC loads (such as the vehicle's control system, emergency lighting system, and service system, including but not limited to speaker systems, multimedia systems, display systems, and station announcement systems) and charging the energy storage battery. The wind turbines generate electricity, and a wind power generation controller connects to the DC loads and the energy storage battery, directly supplying power to the DC loads inside the vehicle body and charging the energy storage battery. The energy storage battery can supply power to AC loads inside the vehicle body (such as mobile phone charging sockets) via an inverter. When the vehicle is underground, the wind turbines generate electricity, and a wind power generation controller connects to the DC loads and the energy storage battery, directly supplying power to the DC loads inside the vehicle body and charging the energy storage battery. The energy storage battery can supply power to AC loads inside the vehicle body via an inverter.

[0028] Traditional wind power generation equipment relies on external wind power. This invention is applied to rail vehicles. During the operation of the rail vehicle, the wind turbine automatically drives to generate electricity to power the load inside the vehicle. It is unaffected by the direction of travel or external factors and does not rely on external wind power. Because it is a fixed track, the wind power generation efficiency is high. It can also recover the airflow energy generated by the vehicle's movement to generate electricity. This invention also uses wind deflectors on the outer periphery of the blades to prevent them from being exposed, ensuring that they will not collide with people or other equipment during travel and arrival at stations, thus improving safety. In summary, this invention is simple, practical, and safe, making it suitable for widespread use.

[0029] It should be noted that the photovoltaic modules, energy storage batteries, generators, transmission mechanisms, photovoltaic power generation controllers, wind power generation controllers, etc. used in this utility model are all implemented using existing products, and are not limited to specific models. The connection relationships of the various components are also existing connection relationships.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
