Description

Technical Field

[0001] This invention belongs to the field of wind power generation technology: specifically, it relates to a vehicle-mounted wind power generation device. Background Technology

[0002] Vehicle-mounted wind power generation devices mainly consist of a wind turbine, a generator, and a controller. When wind blows past the wind turbine, it captures wind energy and converts it into mechanical energy, which is then converted into electrical energy by the generator. The controller is responsible for monitoring and managing the operation of the entire system, ensuring the safe and efficient operation of the device. With continuous technological advancements and the transformation of the energy structure, vehicle-mounted wind power generation devices are expected to be more widely used in the future.

[0003] Existing technologies also offer some solutions: for example, a patent with publication number CN102297085A discloses a vehicle-mounted wind power generation device, including a horn-shaped wind collector, an impeller assembly, a DC generator, and a battery. The impeller assembly includes an impeller and an impeller shaft. The impeller assembly is mounted on the small opening end of the wind collector via a support base. The impeller shaft is connected to the rotor of the DC generator, and the output end of the DC generator is connected to the battery. During vehicle operation, the high-speed relative motion with the air generates a strong wind force. After passing through the wind collector, this wind force is concentrated on the impeller of the impeller assembly, which drives the impeller shaft to rotate, thereby driving the DC generator to generate electricity, which is stored in the battery.

[0004] Vehicle-mounted wind power generation devices are typically placed inside off-road vehicles or campervans. When the vehicle is driven to an open area in the wild, the vehicle-mounted wind power generation device is moved to the top of the off-road vehicle or campervan. The wind turbine captures wind energy from the natural air and converts it into mechanical energy. This mechanical energy is transmitted to the generator through an internal transmission system (such as a reducer). The generator then further converts the mechanical energy into electrical energy, which is stored in the battery for later use.

[0005] When existing vehicle-mounted wind power generation equipment is in use, a wind collector is used to concentrate and guide the airflow, making it more effectively impact the wind turbine blades. However, the use of the wind collector also brings in more lint and dust particles from the air, which accumulate on the wind turbine blades. These accumulated lint particles reduce the angle of attack of the wind on the blades, lowering power generation efficiency. Over time, they accumulate on the critical components of the wind turbine, accelerating the wear and tear of these components.

[0006] Therefore, the present invention provides a vehicle-mounted wind power generation device. Summary of the Invention

[0009] Preferably, the dust removal assembly includes a filter plate located on one side of the wind power generation assembly, and the outer wall of the edge of the filter plate is fixedly connected to the opening of the first wind collector hood, and one side of the second wind collector hood is fixedly connected to one side of the first wind collector hood.

[0010] Preferably, the side of the filter plate facing the second air-collecting hood is set as an arc-shaped surface, the surface of the filter plate is coated with polyester fiber, and the gap between the first air-collecting hood and the second air-collecting hood forms a dust outlet.

[0011] Preferably, a baffle plate is fixedly installed inside the air-collecting hood 2. Both sides of the baffle plate are inclined, and the inner diameter of the baffle plate is smaller than the inner diameter of the filter plate.

[0012] Preferably, an air inlet hood is fixedly connected to one side of the second air-concentrating hood, the opening size of the air inlet hood being the same as the opening size of the second air-concentrating hood, and the air inlet hood being made of high-strength rubber material.

[0013] Preferably, the adjustment assembly includes multiple fixed seats, each fixed seat is uniformly fixedly installed on the outer wall of one end of the air inlet hood, each fixed seat is fixedly connected to one side of an inclined push plate, each inclined push plate is fixedly connected to the outer wall of an inner slider, and the outer wall of the air concentrator hood is fixedly connected to multiple inclined slides, each inner slider is slidably connected to and adapted to the inner groove of each inclined slide.

[0014] Preferably, each inclined push plate is in an inclined state, and multiple inclined slides are fixedly installed on the outer wall of the second wind shroud. Each inclined push plate is provided with a push-pull assembly at one end, which is used to make the inner slider slide up and down along the inner groove of the inclined slide.

[0015] Preferably, the push-pull assembly includes multiple mounting slides, each mounting slide having a threaded conveying rod rotatably connected to its inner wall, each threaded conveying rod having an internal threaded block threaded to its outer wall, each internal threaded block having a sliding connection to the interior of each mounting slide, each internal threaded block having a connector fixedly connected to its top, each connector having an inner groove seat fixedly connected to one end, each inner groove seat having an inner push slider fixedly connected to its inner wall, and each inner push slider having an inner push plate fixedly connected to one end of each inclined push plate.

[0017] Preferably, one end of the wind-gathering cover is fixedly connected to an intercepting grid, and the aperture of the intercepting grid is larger than that of the filter plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The vehicle-mounted wind power generation device of the present invention, through the dust removal component, can intercept the lint before the wind and lint enter the interior of the first wind collector. The intercepted lint will be discharged into the air immediately, while the wind will not be lost into the air. This avoids the lint from entering the interior of the first wind collector and affecting the operation of the blades, and also avoids the lint from accumulating on the outside of the second wind collector and obstructing the wind.

[0020] 2. The vehicle-mounted wind power generation device of the present invention, through the filter plate, allows lint to be blown along the arc-shaped parabolic surface of the filter plate to the edge of the filter plate by the wind. The lint is then blown directly into the air through the dust outlet along the edge. By utilizing the natural action of wind, the lint is effectively removed from the surface of the filter plate, preventing the lint from adhering to the outer wall of the blade. The arc-shaped parabolic surface design not only helps to disperse the lint but also optimizes airflow, reduces air resistance, and improves the overall efficiency of the wind power generation system.

[0021] 3. The vehicle-mounted wind power generation device of the present invention uses a baffle plate to block the edge of the filter plate, so that the wind entering through the wind concentrator second is not blown to the edge of the filter plate under the restriction of the baffle plate, and the wind entering the wind concentrator second will not flow out along the dust outlet. While the fibrous material can be discharged, the wind gathered by the wind concentrator second will not be lost, thus ensuring the efficiency of wind power generation.

[0022] 4. The vehicle-mounted wind power generation device of the present invention allows for adjustment of the size of the opening at one end of the wind inlet shroud according to different speeds via an adjustment component. At high speeds, the opening of the wind inlet shroud is reduced to decrease the force-bearing area of ​​the wind entering the wind-collecting shroud, making the airflow more concentrated and orderly acting on the blades. This reduces the direct impact of the wind on the blades, thereby reducing blade wear. At low speeds, the opening of the wind inlet shroud is enlarged to further increase the force-bearing area of ​​the wind entering the wind-collecting shroud. This effectively guides more airflow into the wind-collecting shroud, capturing more air and improving blade efficiency. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 8 As shown, the present invention provides a technical solution: a vehicle-mounted wind power generation device, including a wind power generation component 1, a wind concentrator 2 on the outside of the wind power generation component 1, a wind concentrator 3 on one side of the wind concentrator 2, one end of the wind concentrator 2 and the wind concentrator 3 being flared, one end of the wind power generation component 1 being fixedly connected to an impeller shaft 23, one end of the impeller shaft 23 being connected to the inside of a control box 4, a telescopic rod 25 being fixedly connected to the bottom of the control box 4, a steering base 24 being fixedly connected to the bottom of the telescopic rod 25, a dust removal component being provided inside the wind concentrator 2, the dust removal component being used to intercept and process lint in the wind, and an adjustment component being provided on one side of the wind concentrator 3, the adjustment component being used to adjust the force-bearing area of ​​the wind entering the wind concentrator 3.

[0035] During operation: When the entire device is not in use, the entire wind power generation unit can be retracted into the interior of an off-road vehicle or campervan using the telescopic rod 25. When the vehicle is driven to an open area in the wild, the telescopic rod 25 is adjusted to move the entire power generation unit to the top of the vehicle, and the openings of the wind concentrator 2 and wind concentrator 3 are aligned with the direction of the natural wind by the steering base 24. Since one end of wind concentrator 2 and wind concentrator 3 is flared, with a large opening area, more airflow can be captured when natural wind blows towards the entire power generation unit. Wind concentrator 2 and wind concentrator 3 can focus more widely distributed wind force and introduce it to the blades of the wind power generation component 1. The blades will rotate after being subjected to wind force, and the mechanical energy of rotation will be transmitted to the generator inside the control box 4 through the impeller shaft 23. The electricity in the generator is conducted to the storage battery for storage, thus completing the wind power generation process. When wind concentrator 2 guides more wind force into the interior of wind concentrator 2, more fibrous material will also enter the wind concentrator along with the wind. Inside the second hood (3), a dust removal component intercepts lint and other particles before they enter the first hood (2). The intercepted lint is immediately discharged into the air, preventing airflow from being lost. This prevents lint from entering the first hood (2) and affecting blade operation, while also preventing lint from accumulating inside the second hood (3) and obstructing airflow. Furthermore, an adjustment component allows for adjustment of the contact area between the airflow and the blades. When the wind is strong in the field, reducing the contact area controls the airflow rate and velocity, making the airflow more concentrated and orderly on the blades, thus reducing direct impact and wear. Conversely, when the wind is weak, increasing the contact area allows for more airflow to be drawn into the second hood (3), capturing more air and improving blade efficiency.

[0036] like Figures 3 to 6 As shown, the dust removal assembly includes a filter plate 5, which is located on one side of the wind power generation assembly 1. The outer edge of the filter plate 5 is fixedly connected to the opening of the wind concentrator 2, and one side of the wind concentrator 3 is fixedly connected to one side of the wind concentrator 2.

[0037] During operation: By turning the base 24, the openings of the second wind collector 3 and the first wind collector 2 are aligned with the direction of the natural wind. Before the wind enters the interior of the first wind collector 2 through the second wind collector 3, it will pass through the surface of the filter plate 5. The filter plate 5 can intercept the lint in the air, thereby preventing the lint from reducing the blades' ability to capture wind energy, accelerating blade wear, and affecting the blades' strength and lifespan when the wind enters the interior of the first wind collector 2 and comes into contact with the blades of the wind power generation component 1.

[0038] like Figures 3 to 5 As shown, the side of the filter plate 5 facing the second air-collecting hood 3 is set as an arc-shaped surface, and the surface of the filter plate 5 is coated with polyester fiber. The gap between the first air-collecting hood 2 and the second air-collecting hood 3 forms the dust outlet 7.

[0039] During operation: Because the side of the filter plate 5 facing the wind-collecting shroud 3 is set with an arc-shaped paraboloid and the surface is coated with polyester fiber, the polyester fiber coating has high strength and the effect of non-adhesion of lint. When the lint is intercepted by the filter plate 5, when the subsequent wind continues to blow towards the surface of the filter plate 5, the lint will be affected by the wind and blown along the arc-shaped paraboloid of the filter plate 5 to the edge of the filter plate 5. The lint will be blown directly into the air through the dust outlet 7 along the edge. By utilizing the natural action of wind, the lint is effectively removed from the surface of the filter plate 5, avoiding the accumulation of lint on the outer wall of the blade. The arc-shaped paraboloid design not only helps to disperse the lint, but also optimizes airflow, reduces air resistance, and improves the overall efficiency of the wind power generation system.

[0040] like Figures 3 to 5 As shown, a baffle plate 6 is fixedly installed inside the wind-collecting hood 2 3. Both sides of the baffle plate 6 are inclined surfaces, and the inner diameter of the baffle plate 6 is smaller than the inner diameter of the filter plate 5.

[0041] During operation: The baffle plate 6 blocks the edge of the filter plate 5, preventing the airflow entering through the wind-collecting hood 2 from reaching the edge of the filter plate 5. Any lint blown into the edge of the filter plate 5 can directly enter the air. The other side of the baffle plate 6 prevents the lint blown to the edge of the filter plate 5 from re-entering the wind-collecting hood 2. Furthermore, because the inner diameter of the baffle plate 6 is smaller than that of the filter plate 5, the airflow entering the wind-collecting hood 2.3 will not flow out along the dust outlet 7. While the lint can be discharged, the air collected by the wind-collecting hood 2.3 will not be lost, ensuring the efficiency of wind power generation.

[0042] like Figure 2 and Figure 8 As shown, an air inlet hood 8 is fixedly connected to one side of the air concentrator hood 2 3. The opening size of the air inlet hood 8 is the same as the opening size of the air concentrator hood 2 3. The air inlet hood 8 is made of high-strength rubber material.

[0043] During operation: By installing a high-strength rubber air inlet shroud 8 on one side of the wind concentrator shroud 2 3, when off-road vehicles and campers are placed in open outdoor environments, the size of the opening at one end of the air inlet shroud 8 can be adjusted according to the wind speed of different natural wind forces. When the natural wind force is strong, the opening of the air inlet shroud 8 is reduced to decrease the force area of ​​the wind entering the wind concentrator 2 3, so that the airflow acts more concentratedly and orderly on the blades, reducing the direct impact force of the wind on the blades, thereby reducing blade wear. When the natural wind force is weak, the opening of the air inlet shroud 8 is enlarged to further increase the force area of ​​the wind entering the wind concentrator 2 3. At this time, more airflow can be effectively guided into the wind concentrator 2 3, capturing more air and improving the working efficiency of the blades.

[0044] like Figures 7 to 8 As shown, the adjustment assembly includes multiple fixed seats 10, each fixed seat 10 is uniformly fixedly installed on the outer wall of one end of the air inlet hood 8, and each fixed seat 10 has a fixedly connected inclined push plate 11 on one side. Each inclined push plate 11 has an inner slider 13 fixedly connected to its outer wall. The outer wall of the air inlet hood 2 3 has multiple inclined slides 12 fixedly connected to it. Each inner slider 13 is slidably connected to the inner groove of each inclined slide 12 and they are mutually adapted.

[0045] During operation: When the opening of the air inlet hood 8 is reduced, multiple inner sliders 13 slide downwards along the inner wall of the corresponding inclined slide 12. At the same time, multiple inclined push plates 11 press down on multiple fixed seats 10. After the multiple fixed seats 10 are pushed down, they will force the opening at one end of the air inlet hood 8 to become smaller. Similarly, when it is necessary to increase the opening of the air inlet hood 8, it is only necessary to make multiple inner sliders 13 slide upwards along the inner wall of the corresponding inclined slide 12.

[0046] like Figures 7 to 8 As shown, each inclined push plate 11 is in an inclined state, and multiple inclined slides 12 are fixedly installed on the outer wall of the wind shroud 2 3. Each inclined push plate 11 has a push-pull assembly at one end, which is used to make the inner slider 13 slide up and down along the inner groove of the inclined slide 12.

[0047] During operation: In the initial state, multiple inner sliders 13 are located at the middle of the inner wall of the corresponding inclined slide 12. By setting the push-pull assembly, the inner sliders 13 slide up and down along the inner groove of the inclined slide 12, thereby adjusting the size of one end of the air inlet hood 8 opening. Since each inclined push plate 11 is in an inclined state, the opening of the air inlet hood 8 can be adjusted to be larger or smaller.

[0048] like Figures 7 to 8 As shown, the push-pull assembly includes multiple mounting slides 18. The inner walls of each mounting slide 18 are rotatably connected to threaded conveying rods 19. The outer walls of each threaded conveying rod 19 are threadedly connected to internal threaded blocks 17. The internal threaded blocks 17 are slidably connected to the interior of each mounting slide 18. The tops of each internal threaded block 17 are fixedly connected to connectors 16. One end of each connector 16 is fixedly connected to an inner groove seat 14. The inner walls of each inner groove seat 14 are fixedly connected to inner push sliders 15. The inner push sliders 15 are fixedly connected to one end of each inclined push plate 11.

[0049] During operation: When multiple threaded conveyor rods 19 rotate, they will drive multiple internal threaded blocks 17 to slide along the inner wall of the mounting slide 18. When the internal threaded blocks 17 slide, they will cause the inner groove seat 14 to move back and forth through the connector 16. When the inner groove seat 14 moves forward, it will squeeze the inner push slider 15, causing the inner push slider 15 to slide in the inner wall of the inner groove seat 14, and force the inclined push plate 11 and the inner slider 13 to slide down along the inner wall of the inclined slide 12, thereby reducing the opening of the air inlet hood 8. Similarly, when the inner groove seat 14 moves backward, it will increase the opening of the air inlet hood 8.

[0050] like Figure 2 and Figure 8 As shown, multiple mounting slides 18 are fixedly installed on the outer wall of the control box 4. A gear 20 is fixedly connected to one end of each threaded conveying rod 19. A motor 22 is fixedly installed at one end of the control box 4. A gear ring plate 21 is fixedly connected to the output shaft of the motor 22. The teeth of the multiple gears 20 mesh with the teeth of the gear ring plate 21 respectively.

[0051] During operation: When the motor 22 is started, its output shaft will drive the gear ring plate 21 to rotate. When the gear ring plate 21 rotates, it will drive multiple motors 22 to rotate at the same time. When multiple gears 20 rotate, they will drive multiple threaded conveying rods 19 to rotate at the same time, thereby achieving the effect of multiple internal thread blocks 17 sliding along the inner wall of the mounting slide 18.

[0052] like Figures 2 to 3 As shown, one end of the wind-collecting cover 3 is fixedly connected to an intercepting grid 9, and the aperture of the intercepting grid 9 is larger than the aperture of the filter plate 5.

[0053] During operation: The interception grid 9 intercepts larger fibrous materials in the air. The intercepted fibrous materials are located inside the air inlet hood 8 and can be discharged when the opening of the air inlet hood 8 is enlarged.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
