Description

Technical Field

[0001] This invention relates to the field of wind power generation technology for rail transit, specifically a multi-dimensional wind power generation system utilizing the airflow entering a high-speed train station. Background Technology

[0002] my country has achieved remarkable results in the development and utilization of natural wind energy, but the airflow resources generated by human disturbance have long been neglected. In my country's existing wind power generation system, the anthropogenic wind power generated by equipment operation and vehicle movement has not been effectively utilized.

[0003] Currently, there are some existing technologies that utilize the airflow generated during rail transit to generate electricity, such as: The railway wind turbine with patent publication number CN2290705Y discloses a wind turbine that utilizes the wind energy from train travel. It features a miniature generator with a fixed main shaft and blades at the rear end of a flat, conical wind tunnel. The wind tunnel body is equipped with mounting hardware for fixed connection to railway sleepers. This invention has significant advantages such as simple structure, no weather restrictions, and reliable operation. However, it can only capture airflow at the bottom of the rails, resulting in low utilization of the high-speed airflow above.

[0004] Patent publication number CN204646532U discloses a wind-solar-thermal-electric complementary wind power generation system utilizing high-speed rail. The system is installed beside the high-speed rail track and includes a wind turbine and a nozzle matched to the front of the wind turbine. The nozzle is a tapered nozzle with a horn at its front end and "fish scale"-shaped ventilation holes on its curved surface. A layer of solar thermal energy collecting material is applied to the outer surface of the nozzle to collect solar thermal energy and transfer it to the inner wall of the nozzle. This utility model has a simple and reasonable structural design, featuring high wind energy utilization, low cost, and energy conservation and environmental protection. However, while it places the wind turbine beside the high-speed rail platform, it is often a single unit and lacks specific hydrodynamic optimization design for the turbine's installation angle.

[0005] When a high-speed train enters a station, the airflow exhibits complex three-dimensional flow characteristics (including turbulence at the bottom, horizontal piston wind in the middle, and lateral flow around the train). Existing technologies typically only capture wind in a single plane or at a single location, failing to comprehensively collect airflow at different heights and in different directions. The capture area of ​​a single fan is limited, resulting in low airflow utilization. Furthermore, fixed angles and fixed fan positions cannot match the airflow direction at different locations and in different directions of the train, leading to large fluctuations in power generation efficiency, resulting in significant waste of wind energy and low power generation efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-dimensional wind power generation system that utilizes the airflow entering a high-speed railway station, in order to solve the problem mentioned in the background art that the existing technology usually only captures wind on a single plane or at a single location, and cannot comprehensively collect airflow at different heights and in different directions, resulting in wind energy waste and low power generation efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-dimensional wind power generation system utilizing the airflow entering a high-speed railway station, comprising: The first power generation unit is horizontally laid out between the ballastless railway tracks to capture airflow under the train. The first power generation unit is equipped with a first wind turbine fan. The second power generation unit is embedded in the side wall of the platform and is used to capture the airflow on the side of the platform and the airflow pushed by the train side wall. The second power generation unit is equipped with a second wind turbine fan inside the platform. The third power generation unit is vertically installed between the two railway tracks to capture horizontal crosswinds. The third power generation unit is equipped with a third wind turbine fan. And a busbar control module electrically connected to the first power generation unit, the second power generation unit and the third power generation unit.

[0009] Preferably, the first power generation unit is installed in a pre-embedded compartment in the middle of the ballastless track. The first power generation unit also includes a guide shroud located outside the first wind turbine fan. The guide shroud is located on the surface of the ballastless track and its height is lower than the height of the rails on both sides. Both ends of the guide shroud are provided with air inlets for airflow to enter. The electromagnetic induction generator below and at the bottom of the first wind turbine fan is located in the pre-embedded compartment, and its top fan blades are horizontally arranged inside the guide shroud.

[0010] Preferably, the second power generation unit has a through airflow guiding channel inside the side wall of the platform, and both ends of the airflow guiding channel are provided with air inlets for airflow to enter, and the air inlets are flush with the side wall of the platform; the blades of the second wind turbine are located in the middle of the airflow guiding channel, and the second power generation unit also has a generator placement channel inside the platform for placing the electromagnetic induction generator on the second wind turbine.

[0011] Preferably, the air inlets at both ends of the airflow guiding channel form an angle of 15-30° with the rail, and the airflow guiding channel is located at a position 0.8m above the platform.

[0012] Preferably, the third power generation unit further includes a fan protective shell disposed outside the third wind turbine fan and a connecting seat connected to the bottom of the fan protective shell.

[0013] Preferably, the third power generation unit is provided with a steering mechanism at the bottom of the connecting seat, and the third power generation unit is also provided with an infrared ranging sensor, which is electrically connected to the steering mechanism through a controller.

[0014] Preferably, the third power generation unit is provided with a steering mechanism at the bottom of the connecting seat, and the third power generation unit is also provided with a wind speed and direction sensor, which is electrically connected to the steering mechanism through a controller.

[0015] Preferably, the bus control module includes a three-way parallel bus circuit for power generation output, an anti-reverse current diode, an overcurrent protector, an MPPT maximum power point tracking controller, a rectification and voltage regulation unit, and an energy storage interface.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The multi-dimensional wind power generation system that utilizes the airflow of high-speed rail entering the station forms a three-dimensional layout by embedding the first power generation unit, the second power generation unit and the third power generation unit under the rail, on the platform wall and between the rails. It can capture the multi-dimensional airflow such as the strong turbulence at the bottom, the horizontal piston wind in the middle and the lateral shock wave generated by the high-speed rail entering the station. Thus, it can generate electricity in the station area by utilizing the multi-dimensional disturbed airflow generated by the high-speed rail entering the station. This changes the limitations of the traditional single location and single wind turbine wind capture and improves the power generation efficiency.

[0017] (2) The second power generation unit of the multi-dimensional wind power generation system utilizing the airflow of high-speed trains entering the station is set with a fixed tilt angle of 15-30°, which can match the propagation trajectory of the shock wave of the high-speed train head, so that the wind energy capture efficiency reaches the optimal level. At the same time, the third power generation unit adopts a sensor-based steering mechanism, which can automatically rotate the fan's windward surface to face the direction of the oncoming train before the train enters the station, effectively overcoming the energy loss caused by the wind direction deviation angle of the fixed wind turbine.

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figure 1-13This invention provides a technical solution: a multi-dimensional wind power generation system utilizing the airflow from a high-speed train entering a station, comprising a first power generation unit 1, a second power generation unit 2, and a third power generation unit 3, as well as a combiner control module electrically connected to the first power generation unit 1, the second power generation unit 2, and the third power generation unit 3. The first power generation unit 1 is horizontally positioned between ballastless rails to capture airflow under the train, and a first wind turbine fan 102 is installed inside the first power generation unit 1. The second power generation unit 2 is embedded in the side wall of the platform to capture airflow from the side of the platform and airflow pushed by the train side wall, and a second wind turbine fan 203 is installed inside the second power generation unit 2. The third power generation unit 3 is vertically positioned between two rails to capture horizontal lateral wind, and a third wind turbine fan 302 is installed inside the third power generation unit 3. The first power generation unit 1, the second power generation unit 2, and the third power generation unit 3 form a three-dimensional wind-capturing array, which can effectively generate electricity from the multi-dimensional disturbed airflow generated by the high-speed train entering the station.

[0022] The first wind turbine 102, the second wind turbine 203, and the third wind turbine 302 have the same structure, only differing in their installation positions within each unit. They are equipped with fan blades on top and an electromagnetic induction generator 4 connected to the bottom via a gear set. The fan blades are rotated by airflow, which in turn drives the electromagnetic induction generator 4 to cut magnetic field lines and generate electricity.

[0023] Specifically, the first power generation unit 1 is installed in the pre-embedded compartment in the middle of the ballastless track. The first power generation unit 1 also includes a guide shroud 101 located outside the first wind turbine fan 102. The guide shroud 101 is located on the surface of the ballastless track, and its height is lower than the height of the rails on both sides. Both ends of the guide shroud 101 are provided with air inlets for airflow entry. The electromagnetic induction generator 4 below and at the bottom of the first wind turbine fan 102 is located in the pre-embedded compartment, and its top fan blades are horizontally arranged inside the guide shroud 101. The first power generation unit 1 is laid flat between the ballastless rails, and its output line is connected to the track control box through a conduit. When the train is running, the airflow generated at the bottom of the train acts on the first wind turbine fan 102 inside the guide shroud 101 through the air inlets at both ends of the guide shroud 101, thereby generating electricity by capturing the high-speed downward airflow and piston wind at the bottom of the train. In this embodiment, the first wind turbine fan 102 is 20 cm high, and the overall height is 25 cm after the addition of the deflector 101. The distance from the lower plane of the obstacle remover to the bottom plate (bottom surface) of the ballastless track is 40 cm. After the device is installed, there is still a 15 cm margin between the top of the device and the obstacle remover. This margin can effectively prevent structural interference between the device and the obstacle remover, and provide convenient conditions for airflow and subsequent maintenance. At the same time, the overall height of 25 cm takes into account both installation feasibility and wind capture capability within the limited space under the vehicle, and matches the 40 cm ground clearance of the obstacle remover, forming a reasonable spatial layout.

[0024] The second power generation unit 2 has a through airflow guiding channel 201 inside the side wall of the platform. Both ends of the airflow guiding channel 201 are provided with air inlets for airflow to enter, and the air inlets are flush with the side wall of the platform. The blades of the second wind turbine fan 203 are located in the middle of the airflow guiding channel 201. The second power generation unit 2 also has a generator placement channel 202 inside the platform for placing the electromagnetic induction generator 4 on the second wind turbine fan 203. The cables of the second power generation unit 2 can be converged along the platform's concealed pipes. Furthermore, the air inlets at both ends of the airflow guiding channel 201 form an angle of 15-30° with the rails. This 5-30° angle matches the trajectory of the high-speed train's shock wave as it obliquely rushes upwards towards the platform. The airflow guiding channel 201 is located at a platform height of 0.8m, with the windward side of the air inlet facing the main direction of the train's entry into the station. The second power generation unit 2, by opening a through-type bidirectional airflow guiding channel 201, effectively guides the high-speed airflow generated on the platform edge to the windward side of the second wind turbine fan 203, thereby achieving the combined capture and utilization of bidirectional airflow. Power generation is achieved by capturing the airflow from the platform side and the pushing airflow from the train sidewall. The bidirectional channel 201 can simultaneously respond to trains approaching from different directions on both sides of the high-speed railway station. Whether the train is entering from the upper or lower direction, the corresponding piston airflow can be quickly directed to the second wind turbine 203, avoiding energy waste caused by a single train direction and significantly improving the system's all-weather utilization rate. The airflow guiding channel 201 can rectify and accelerate the airflow, reducing turbulence losses and energy dissipation during the diffusion of airflow from the platform edge to the second wind turbine 203, allowing more kinetic energy to be concentrated on the blades. The 0.8m height position avoids interference from normal passenger passage and safety doors, and is located in a space area with relatively concentrated air pressure, resulting in higher wind capture efficiency. This structure is constructed using pre-embedded or embedded methods, without damaging the original structural integrity of the platform. Furthermore, the inner wall of the airflow guiding channel 201 can be smoothed to reduce frictional resistance, requiring no maintenance for long-term operation.

[0025] The third power generation unit 3 also includes a fan protective shell 301 disposed outside the third wind power fan 302 and a connecting seat 303 connected to the bottom of the fan protective shell 301. The third power generation unit 3 is set on both sides of the railway track, with good versatility and site adaptability. It can be flexibly deployed along the tracks of major high-speed railway stations across the country. It is specifically used to absorb the instantaneous high-speed turbulent airflow generated when high-speed trains pass through the station. At the same time, the arrangement on both sides of the railway track does not occupy the traffic clearance. The installation position is flexible and can cover both the up and down lines at the same time. It does not require large-scale modification of the original civil engineering structure of the station. It is suitable for the energy-saving upgrade of existing stations and the integrated design of new stations. Furthermore, the third power generation unit 3 is equipped with a steering mechanism at the bottom of the connecting seat 303. The third power generation unit 3 is also equipped with an infrared ranging sensor. The steering structure includes a servo motor and a gearbox. The infrared ranging sensor is electrically connected to the servo motor via a controller. The infrared ranging sensor can be installed on the fan protective shell 301 or the connecting seat 303. When the infrared ranging sensor detects that a high-speed train is about to enter the station or is passing by at high speed, the control system will drive the connecting seat 303 to rotate horizontally by approximately 60 degrees via the servo motor, aligning the third wind turbine fan 302 with the direction of the oncoming train. This ensures that the wind-catching surface forms the optimal angle of attack with the mainstream airflow, thereby significantly increasing the amount of kinetic energy captured per unit time. The use of an infrared ranging sensor enables non-contact oncoming train detection. It should be rapid, have strong anti-interference capabilities, and be unaffected by environmental factors such as rain, snow, and dust. It should be able to detect the distance and speed of trains on the track ahead in real time and continuously, and complete the turning action in a very short time when the train approaches. In this way, the third wind turbine 302 can enter the optimal windward posture in advance to ensure the maximum wind capture window. At the same time, setting a rotation angle of 60 degrees can avoid wind energy loss caused by parallel arrangement and prevent structural interference or response delay caused by excessive turning amplitude. This adaptive wind mechanism effectively solves the energy waste problem caused by the single direction of traditional fixed wind capture devices. Especially in the typical working condition of high-speed rail bidirectional shuttle operation, it can improve the overall wind capture efficiency of the system, thereby converting more waste airflow energy into usable electricity.

[0026] The combined power control module includes three parallel power output circuits, anti-reverse diodes, overcurrent protectors, an MPPT (maximum power point tracking) controller, a rectification and voltage regulation unit, and an energy storage interface. The energy storage interface can be connected to a lithium battery pack to power the station lighting, signs, monitoring, etc. The three power generation units convert wind energy into electrical energy and output it to the combined power control module. The combined power control module performs parallel combining, MPPT, and rectification and voltage regulation on the three power outputs before outputting them to the energy storage battery or directly connecting them to the low-voltage electrical equipment in the station area.

[0027] Example 2 This embodiment provides another steering scheme for the third power generation unit 3. The difference from the previous embodiment is that the third power generation unit 3 is equipped with a wind speed and direction sensor and a controller to control the servo motor. The wind speed and direction sensor can also be installed on the fan protective shell 301 or the connecting seat 303. The controller controls the servo motor to drive the connecting seat 303 according to the wind direction signal detected by the wind speed and direction sensor so that the rotation plane of the blades of the third wind power generator 302 is always perpendicular to the wind direction, thereby adjusting the windward attitude in real time to maximize the utilization of airflow.

[0028] Theoretical design calculations for this system: Airflow velocity calculation Unit 1 (Below the Track) – Bottom Turbulent Velocity Increased flow velocity in the gap under the rails: V1= Vtrain×Atrain / Agap×Kturb Where Atrain is the cross-sectional area of ​​the train's bottom, calculated to be 12 m² based on official train data: width ≈ 3.4 m, bottom height ≈ 3.5 m. Agap is the cross-sectional area of ​​the rail clearance ≈ 1.5 m². Kturb is the turbulence enhancement coefficient, taken as 1.3. Considering the influence of viscous dissipation and compressibility of the airflow under the rails, the following adjustments were made based on official Chinese railway science popularization articles: V1=18m / s Unit 2 (Platform) – Lateral Impact Velocity Shock wave speed from the front of the car: V2 = Vtrain × Kimpact Wherein, Kimpact is the impact enhancement coefficient, which is derived after adjusting for the installation height of the generator on the platform: V2=22m / s Unit 3 (Inter-orbit) – Horizontal Flow Velocity Airflow speed along the side of the vehicle body: V3 = Vtrrain × Kside Where Kside is the lateral flow coefficient, which is set to 0.9 since the lateral flow rate is slightly lower than the vehicle speed. The calculations show that: V3=18m / s Theoretical wind energy capacity: Pwind=1 / 2pAv3 Where v represents the wind speed of the first, second, and third unit modules, respectively. The calculation shows that: P1=1011W P2=1226W P3=1797W Actual power generation: Pout=Pwind×Cp×η gen×η mech Where Cp is the wind energy utilization coefficient, ηgen is the generator efficiency, and ηmech is the mechanical transmission efficiency.

[0029] The calculation shows that: Ptotal=237+355+584=1176≈1.18kw Effective power generation duration The change in power generation during the high-speed train's entry into the station over time Phase duration power ratio The train head enters the station in 5 seconds (100%). The car body passes through 80% in 20 seconds. The rear of the car is 50% away from the destination in 5 seconds. The equivalent duration is calculated as follows: t eq=24s Calculation of single power generation: Esingle=Ptotal×t eq =1.18kw×24s / 3600h=7.87wh That is, the power generation per single inlet is approximately 7.9Wh. According to publicly available data, high-speed rail stations in major prefecture-level cities (regional hubs) in my country generally have 6-12 platforms, while those in provincial capitals (large hubs) generally have 13-18 platforms. Each platform is equipped with an average of 3-5 generators. Taking the minimum average of 9, the following calculations are made: The power generation per station per trip is approximately 71.1 ≈ 71 Wh. Calculation of average daily power generation: Edaily = Esingle × Ndaily Where N represents the average number of trains arriving at the station per day. According to publicly available data, the throughput of high-speed rail stations in major prefecture-level cities in my country is 150-250 trains, that of ordinary provincial capital high-speed rail stations is 400-600 trains, and that of high-powered provincial capital high-speed rail stations is 600-1200 trains.

[0030] Therefore, N is taken as the minimum average value of 400. The calculation shows that: Edaily=28400wh=28.4kWh≈28kWh Considering system availability and routine downtime for maintenance: Ed = 28 × 90% = 25.2 kWh ≈ 25 kWh Annual power generation calculation: Eannual = 25 × 365 = 9125 kWh Replace carbon emissions from coal-fired power plants Average carbon emission factor of China's power grid: EF = 0.5777 kg CO2 / kWh (Released in October 2025) Annual carbon emission reduction: CO2 = Eannual × EF = 5265.125 kg ≈ 5.3 tons Working principle: When using this multi-dimensional wind power generation system that utilizes the airflow of high-speed trains entering the station, when the high-speed train enters the station, the first power generation unit 1 can capture the high-speed downward airflow and piston wind at the bottom of the train, and drive the electromagnetic induction generator 4 to generate electricity through the first wind turbine fan 102. The second power generation unit 2 captures the shock wave and lateral squeezing airflow at the front of the train through the airflow guide channel 201. The airflow acts on the second wind turbine fan 203 to drive the electromagnetic induction generator 4 to generate electricity. The third power generation unit 3 can automatically rotate the connecting seat 303 through the sensor to make the blades of the third wind turbine fan 302 align with the direction of the oncoming train and capture the horizontal lateral wind, thereby driving the electromagnetic induction generator 4 to generate electricity. The three power generation units convert wind energy into electrical energy, which is then connected to the energy storage or power supply circuit for use after voltage stabilization and rectification.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
