Description

Technical Field

[0001] This invention relates to the fields of new energy vehicles and wind power generation technology, specifically to a vehicle-mounted wind power generation system and method that integrates wind power regulation and self-cleaning. Background Technology

[0002] With the popularization of new energy vehicles, improving driving range has become a core demand for technological development. Utilizing wind energy generated while vehicles are in motion to generate electricity is an effective supplementary energy solution and has attracted widespread attention from the industry.

[0003] However, existing vehicle-mounted wind power generation technologies have significant drawbacks: First, most systems cannot operate efficiently and stably across a wide wind speed range, and generators are easily damaged at excessively high wind speeds. Second, the system control strategies are relatively crude, relying heavily on linear or fuzzy control and lacking precise hierarchical control strategies, resulting in low energy capture efficiency. Furthermore, dust and debris easily accumulate on the blade surface during long-term operation, not only disrupting the dynamic balance of rotating components and affecting power generation efficiency, but also accelerating equipment wear; currently, there is no effective online cleaning solution. In addition, existing wind power generation units are often retrofitted as external modules without sufficient consideration for integration with the vehicle's overall design, which can easily disrupt the vehicle's original aerodynamic characteristics, increase wind resistance, and negatively impact driving range.

[0004] Therefore, there is an urgent need to develop a vehicle-mounted wind power generation system that has autonomous environmental perception capabilities, can perform intelligent hierarchical regulation based on wind conditions, and integrates efficient self-cleaning functions. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, this application proposes the following technical solution: In a first aspect, embodiments of this application provide a vehicle-mounted wind power generation system integrating wind power regulation and self-cleaning, comprising: an air duct system, a generator set, an intelligent control module, and a wind sensor, a wind speed regulation system, and a mechanical linkage self-cleaning system electrically connected to the intelligent control module. The air duct system is used to capture high-speed airflow during driving. The intelligent control module controls the wind speed regulation system to regulate the wind speed according to the wind intensity signal obtained by the wind sensor, and then generates electricity through the generator set. At the same time, it controls the mechanical linkage self-cleaning system to perform self-cleaning under preset conditions.

[0006] In one possible implementation, the air duct system includes an air inlet disposed on the upper surface of the car hood, the air inlet being connected to a flow channel, a removable multi-layer filter screen being disposed at the air inlet, and a wind speed regulation system being disposed at the rear end of the multi-layer filter screen.

[0007] In one possible implementation, the wind speed regulation system includes a louvered air guide plate disposed in the airflow channel. The louvered air guide plate is connected to an air guide plate drive mechanism. A first electronic wind sensor is disposed between the louvered air guide plate and the multi-layer filter screen. A second electronic wind sensor is disposed between the louvered air guide plate and the generator set. The air guide plate drive mechanism, the first electronic wind sensor, and the second electronic wind sensor are all electrically connected to an intelligent control module.

[0008] In one possible implementation, the generator set includes a wind turbine blade disposed at the end of the flow channel and a permanent magnet synchronous generator connected to the wind turbine blade. The permanent magnet synchronous generator is electrically connected to the input terminal of the power management unit, and the output terminal of the power management unit is electrically connected to the vehicle battery.

[0009] In one possible implementation, the mechanical linkage self-cleaning system includes: a dust removal air duct, the inlet end of which is located on the windward side of the louvered air guide plate, the outlet end of which faces the back of the fan blades, a control valve on the dust removal air duct, the control valve being connected to a mechanical linkage mechanism, the mechanical linkage mechanism being connected to an air guide plate drive mechanism, and the air guide plate drive mechanism being connected to the louvered air guide plate.

[0010] Secondly, embodiments of this application provide a vehicle-mounted wind power generation method integrating wind power regulation and self-cleaning, comprising: The initial wind speed entering the guide channel is obtained through the first wind sensor; The acquired raw wind speed is compared with the preset wind speed threshold to determine the current operating level of the system. After adjusting the opening of the louvered air guide plate according to the determined working position, the wind speed of the fan blades is obtained through the second wind force sensor. The wind speed of the acquired fan blades is used as a feedback signal to fine-tune the opening of the louvered air guide plate. After fine-tuning, the generator set generates electricity and delivers the generated power to the vehicle battery.

[0011] In one possible implementation, comparing the acquired raw wind speed with a preset wind speed threshold to determine the system's current operating level includes: When the original wind speed is less than 20 km / h, it is determined to be the first gear; When the original wind speed is greater than or equal to 20 km / h and less than 50 km / h, it is determined to be the second gear; When the original wind speed is greater than or equal to 50 km / h and less than 120 km / h, it is determined to be the third gear. When the original wind speed is greater than or equal to 120 km / h and less than 160 km / h, it is determined to be the fourth gear. When the acquired original wind speed is greater than or equal to 160 km / h and less than 200 km / h, it is determined to be the fifth gear; When the original wind speed is greater than 200 km / h, it is determined to be in the over-limit gear.

[0012] In one possible implementation, adjusting the opening of the louvered air guide plate according to a determined working position includes: When the system is in the first gear, the opening of the louvered air guide is controlled to 0%, the louvered air guide is closed, the system does not generate electricity, and passive self-cleaning is triggered; When the system is in the second gear, the opening of the louvered air guide is controlled to be 80%-100%, and maximum power point tracking is performed. When the system is in the third gear, the opening of the louvered air guide is controlled to be 60%-80%, and constant voltage charging is performed. When the system is in the fourth gear, the opening of the louvered air guide is controlled to be 30%-60%, and constant power output is executed. When the system is in the fifth gear, the opening of the louvered air guide is controlled to be 10%-30%, and power reduction operation is performed. When the system is in the over-limit position, the opening of the louvered air guide is controlled to 0%, the louvered air guide is closed, the system is locked and passive self-cleaning is triggered.

[0013] In one possible implementation, triggering passive self-cleaning includes: When the original wind speed is less than 20 km / h or greater than 200 km / h, the louvered wind deflector is rotated to a fully closed state. The mechanical linkage mechanism synchronously opens the control valve, allowing external airflow to be blown onto the fan blades through the dust removal pipe, thus achieving passive self-cleaning.

[0014] One possible implementation also includes active pulse self-cleaning, where active pulse self-cleaning is triggered by the intelligent control module based on a preset timing period and / or the cumulative operating time of the system calculated from wind sensor data when the system is generating electricity normally. The intelligent control module, based on a preset timing period and triggered active pulse self-cleaning, includes: The intelligent control module initiates a cleaning command at regular intervals and then controls the louvered air guide plate to close quickly. The mechanical linkage mechanism opens the control valve simultaneously, allowing external airflow to be blown onto the fan blades through the dust removal pipe; After maintaining the preset time, the louvered air guide plate is restored to its original opening and the control valve is closed to achieve pulsed airflow self-cleaning.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This application employs an independent air intake on the upper part of the hood, with a built-in filter and dual wind speed sensors. Through five-level graded control, it achieves refined and optimized management over a wide wind speed range. Simultaneously, it innovatively designs a mechanical linkage self-cleaning system and integrates active pulse cleaning logic into the intelligent control module, realizing intelligent and seamless online dust removal with zero additional energy consumption. This fundamentally solves the industry problem of dust accumulation affecting dynamic balance. The system boasts precise control, rapid response, and extremely high reliability, significantly enhancing the commercial application value of vehicle-mounted wind power generation.

Detailed Implementation

[0018] The present solution will now be described in conjunction with the accompanying drawings and specific embodiments.

[0019] Figure 1 A schematic diagram of the overall structure of a vehicle-mounted wind power generation system integrating wind power regulation and self-cleaning, provided as an embodiment of this application, is shown below. Figure 1This application provides a vehicle-mounted wind power generation system integrating wind power regulation and self-cleaning, comprising: a wind duct system, a generator set, an intelligent control module, and a wind sensor, a wind speed regulation system, and a mechanical linkage self-cleaning system electrically connected to the intelligent control module. The wind duct system is used to capture high-speed airflow during driving. The intelligent control module controls the wind speed regulation system to regulate the wind speed based on the wind intensity signal obtained by the wind sensor, and then generates electricity through the generator set. At the same time, it controls the mechanical linkage self-cleaning system to perform self-cleaning under preset conditions.

[0020] See Figure 2 In this embodiment, the intelligent control module is used to process wind sensor signals and output control commands, and has a built-in five-level graded control strategy and active cleaning logic.

[0021] See Figure 3 In this embodiment, the air duct system includes an air inlet 2, which is independently located on the upper surface of the car hood 1. It features a concealed, low-resistance design and is connected to the airflow channel. A detachable multi-layer composite air filter is installed at the air inlet 2. External airflow enters from the air inlet 2 on the upper surface of the hood 1 and passes through the multi-layer filter 3. A wind speed regulation system is located at the rear end of the multi-layer filter 3. In this embodiment, the wind speed regulation system includes a louvered air guide plate 5 installed within the airflow channel. The louvered air guide plate 5 is connected to an air guide plate drive mechanism 6. A first electronic wind sensor 4 is installed between the louvered air guide plate 5 and the multi-layer filter 3, and a second electronic wind sensor 7 is installed between the louvered air guide plate 5 and the generator set. The air guide plate drive mechanism 6, the first electronic wind sensor 4, and the second electronic wind sensor 7 are all electrically connected to an intelligent control module.

[0022] See Figure 4 In this embodiment, the generator set includes a wind turbine blade 8 disposed at the end of the flow guide channel and a permanent magnet synchronous generator 10 connected to the wind turbine blade 8. The wind turbine blade 8 is designed in imitation of the blade shape of a low-bypass ratio aero-engine, and in this embodiment, carbon fiber wind turbine blades are used. The generator is connected to the vehicle body via a shock-absorbing base. The permanent magnet synchronous generator 10 is electrically connected to the input terminal of the power management unit 9, and the output terminal of the power management unit 9 is electrically connected to the vehicle battery 12. In this embodiment, the power management unit 9 is used to process the electrical energy generated by the generator and deliver it to the vehicle battery.

[0023] See Figure 5In this embodiment, the mechanical linkage self-cleaning system includes: a dust removal air pipe, the inlet end of which is located on the windward side of the louvered air guide plate 5, and the outlet end of which faces the back of the carbon fiber fan blades. A control valve 11 is installed on the dust removal air pipe, and a mechanical linkage mechanism connects the control valve 11 to the air guide plate drive mechanism 6. When the louvered air guide plate 5 rotates to a fully closed state, the control valve 11 is simultaneously opened via the mechanical linkage mechanism, allowing external airflow to pass through the dust removal air pipe and blow onto the fan blades 8, thus achieving self-cleaning.

[0024] Furthermore, the system can automatically diagnose faults by comparing the data from the first electronic wind sensor 4 and the second electronic wind sensor 7.

[0025] See Figure 6 Corresponding to the vehicle-mounted wind power generation system integrating wind power regulation and self-cleaning provided in the above embodiments, this application also provides a vehicle-mounted wind power generation method integrating wind power regulation and self-cleaning, comprising: S101, the original wind speed entering the guide channel is obtained through the first wind sensor 4.

[0026] S102, compare the acquired raw wind speed with the preset wind speed threshold to determine the current operating level of the system.

[0027] Table 1. Five-Tier Control Strategy Table Referring to Table 1, the five-level graded control strategy table provided in this embodiment determines the level 1 when the acquired original wind speed is less than 20 km / h. When the original wind speed is greater than or equal to 20 km / h and less than 50 km / h, it is determined to be gear 2; When the original wind speed is greater than or equal to 50 km / h and less than 120 km / h, it is determined to be gear 3; When the original wind speed is greater than or equal to 120 km / h and less than 160 km / h, it is determined to be gear 4; When the original wind speed is greater than or equal to 160 km / h and less than 200 km / h, it is determined to be gear 5; When the original wind speed is greater than 200 km / h, it is determined to be in the over-limit gear.

[0028] S103, after adjusting the opening of the louvered air guide plate according to the determined working position, obtains the wind speed of the fan blades through the second wind force sensor.

[0029] See Figure 7In this embodiment, when the system is in position 1, the louvered air guide vane opening is controlled to 0%, the vane is closed, the system does not generate electricity, and passive self-cleaning is triggered. When the system is in position 2, the louvered air guide vane opening is controlled to 80%-100%, and maximum power point tracking is performed. When the system is in position 3, the louvered air guide vane opening is controlled to 60%-80%, and constant voltage charging is performed. When the system is in position 4, the louvered air guide vane opening is controlled to 30%-60%, and constant power output is performed. When the system is in position 5, the louvered air guide vane opening is controlled to 10%-30%, and reduced power operation is performed. When the system is in the over-limit position, the louvered air guide vane opening is controlled to 0%, the vane is closed, the system is locked, and passive self-cleaning is triggered.

[0030] When the original wind speed is less than 20 km / h or greater than 200 km / h, the louvered air guide plate is rotated to a fully closed state, and the linkage valve is opened synchronously through the mechanical linkage mechanism, so that the external airflow is blown onto the carbon fiber fan blades through the dust removal air pipe, thereby achieving passive self-cleaning.

[0031] In addition, it also includes active pulse self-cleaning. When the system is generating electricity normally, the intelligent control module triggers active pulse self-cleaning based on a preset timing period and / or the cumulative operating time of the system calculated based on wind power sensor data. In this embodiment, under normal power generation conditions, the intelligent control module controls the air guide vane drive mechanism to execute a cleaning command sequence: First, after the intelligent control module initiates the cleaning command at a set time, it controls the louvered air guide vane to close quickly. Then, the linkage valve is opened synchronously through the mechanical linkage mechanism, allowing external airflow to blow onto the carbon fiber fan blades through the dust removal air pipe. After maintaining this for a preset time of 0.5-2 seconds, the louvered air guide vane is restored to its original opening and the linkage valve is closed, thus achieving pulsed airflow self-cleaning.

[0032] S104 uses the wind speed of the acquired fan blades as a feedback signal to fine-tune the opening of the louvered air guide plate.

[0033] S105, after fine-tuning, uses a generator set to generate electricity and transmits the generated electricity to the vehicle battery.
