Description

Technical Field

[0001] 1. The present invention relates to a method for increasing wind speed of a vehicle and utilizing wind energy.

[0002] 2. A device for increasing wind speed and utilizing wind energy in a vehicle. Background Art

[0003] 3. Air energy is huge, but it is difficult to use due to reasons such as low energy density. In the existing technology, the capacity of a single wind power generator is generally small and the efficiency is low. These are mostly introduced in professional books on wind power. According to fluid mechanics, high-speed wind will drive the surrounding low-speed wind to flow together. If the air energy density can be increased and wind speed wind power generation can be increased, then air energy may become an important energy source for vehicles. When a vehicle is driving, it will generate a wind speed higher than the surrounding air. This wind is the wind resistance generated by the vehicle's energy consumption, but it is connected to the atmosphere, and the original wind force and wind resistance of nature exist at the same time. If the high-speed wind generated by the vehicle during driving is used as the initial energy source, and the wind energy in the atmosphere is introduced into the generator for power generation, it can provide new energy for vehicles.

[0004] 4. In the prior art, the wind wheel of the wind turbine is directly exposed to the air, relying on natural wind to generate electricity. The natural wind in the air directly acts on the wind wheel, which is a matter of relying on nature and directly utilizing natural wind power.

[0005] 5. In many cases of the prior art, wind turbines are installed on the roof of the car, which increases the frontal projection area of ​​the car. According to the aerodynamics of the car, even if it is stationary and not generating electricity, it will increase the wind resistance and disrupt the air flow field of the car. The unidirectional rotation of the wind blades will inevitably generate huge unidirectional force, which is dangerous at high speeds.

[0006] 6. Many existing technologies use headwind power generation. If the wind force is increased, the resistance to the vehicle's advancement will increase. In many existing technologies, no matter where the generator is installed, the impeller is subjected to headwind force, and the force direction is opposite to the vehicle's forward direction. While generating electricity, the impeller will be pushed backward, which will generate a component force that pushes the vehicle backward. On a moving vehicle, the foundation is not stationary, and this backward thrust will act as a resistance to the moving vehicle. The greater the power generation, the greater the backward thrust. However, the principle of a wind turbine requires the impeller to rotate against the wind. This makes the impeller movement contradictory to the vehicle's advancement. Refer to Chinese Patent Application No. 202011167366.X; Chinese Patent Application No. 202011327790.6; Chinese Patent Application No. 202011163555.X; Chinese Patent Application No. 202211278305.X; Chinese Patent Application No. 202011200227.2. Of course, this does not mean that they are wrong. The point of their invention is not to solve the problem of generator location or generating electricity against the wind. They can generate electricity without solving these two problems, but it will require vehicles to consume more energy for generating electricity.

[0007] 7. Aerodynamic design principles of cars. When a car is driving, air flows around and inside the car. Figure 6 , Figure 7 , Figure 8 It is the air flow field outside the car published in the professional book "Automotive Aerodynamics" (written by Fu Limin). The air flow around the car body flows along the car body, and after leaving the car body behind the car, the air flow direction rotates. If these air flow fields outside the car body are combined, the original flow direction is followed, and new wind power is absorbed, it will be a new aerodynamic technology.

[0008] 8. Reference Fig.10 The invention is a technology of China Patent Application No. 202310101075.8. The name of the invention is: "Method and device for self-generated compressed wind power generation by vehicle". The invention is based on aerodynamics, Bernoulli equation, Venturi effect, and jet theory. Before the wind enters the generator, the airflow is guided to change, so that the airflow follows the flow direction that conforms to aerodynamics, and accelerates, exhausts, inhales, and compresses while moving, so as to form four working processes of the compressor and complete the function of the compressor. This technical feature contains the above theory, and one of the key reasons why it can complete the function of the compressor is that it has a process of converting speed into pressure, that is, the pressurization process. However, what the generator ultimately requires is high-speed wind energy. As long as the generator can obtain more kinetic energy, whether the acceleration process before power generation is pressurized or whether it has the function of a compressor is not a requirement for power generation. Therefore, there is also a new technology that abandons the pressurization part and only obtains wind energy by acceleration. This technology has a simple method and a simple structure. It can be used for low vehicle speeds as well as high vehicle speeds, but it fundamentally changes the nature of the original technology. Summary of the invention

[0009] 1. The present invention is a method and device for increasing wind speed and expanding wind energy generation in vehicles. The present invention is based on the Bernoulli equation, Venturi effect, jet mechanics, and vehicle aerodynamics theory to accelerate and expand air. The content of the present invention is to increase the wind speed of vehicles while driving, suck in more air and accelerate; in this way, wind energy higher than the surrounding speed can be obtained, which is to improve the problem of low air energy density described in the background technology, and to a certain extent, the energy density can be increased by speed.

[0010] 2. The present invention processes the wind, accelerates it, and expands its energy before generating electricity, which is essentially different from the existing wind power generation technology that directly utilizes natural wind. The airflow channel is arranged in front of the wind turbine and before driving the wind wheel. Before generating electricity, a wind with a higher wind speed and increased energy than the surrounding environment is formed, and then this airflow with increased wind speed drives the wind wheel to generate electricity. This is a change from the background technology described in this article, in which the wind wheel of the prior art generator is directly exposed to the air and uses the natural wind to generate electricity. Before the wind drives the wind wheel, the device of the present invention is used to first guide the airflow to increase its speed and expand its kinetic energy. Then, the airflow with increased speed drives the wind wheel with greater wind force to obtain more electrical energy.

[0011] 3. Airflow acceleration methods and components. The acceleration unit channel refers to the channel section where the flow cross-sectional area decreases from the inlet to the outlet, such as the sections (101) to (104) and (105) to (107) in the attached drawings. They are the basic components for increasing the wind speed in the method and device of the present invention. According to the Bernoulli equation, the wind speed increases due to the reduction of the cross-sectional area; a Venturi effect is generated; and the wind is ejected at the outlet at a higher wind speed than the surrounding wind speed, which represents the jet phenomenon generated at the outlet. This is a feasible phenomenon based on the jet principle. The flow cross-sectional area refers to the cross-sectional area of ​​the flow channel that is nearly perpendicular to the flow direction.

[0012] 4. Energy expansion method and device for increasing wind speed and sucking in more air for acceleration. Combine several sections of acceleration unit channels into multiple columns and multiple sections of channels, and each column of channels is formed by connecting several sections of acceleration unit channels; the airflow in the previous section of the acceleration unit channel is accelerated due to the narrowing of the flow channel, and after being ejected from the outlet at high speed, it enters the opening of the next section of the channel; here, according to the jet theory, the gas flows out through small holes, gaps, etc. at a certain speed, and a boundary airflow will be formed within a certain distance, and its boundary will remain unchanged when flowing in a certain direction; therefore, after the previous section of the airflow flows out, it will not disperse, there will be no loss, and it can all enter the next section of the channel, so that all the wind energy of the previous section is sent to the next section of the channel. At the same time, because the wind speed is high, the suction drives the surrounding air to flow together, and more wind from the outside flows together and enters the next section of the channel, which is to expand the wind energy. For example, the outlet (104) section in the attached figure is connected with the inlet (105) of the next section to form a two-section accelerated energy-expanding airflow channel. When the airflow flies into the inlet (105), the air outside the channel is sucked into the inlet (105) to achieve energy expansion. In the sections (105) to (107), the cross-sectional area of ​​the channel flow gradually decreases, and the airflow after energy expansion is accelerated and ejected through the outlet (107); in the airflow channels of several columns and several sections, the same logic is applied to generate several acceleration and jet suction processes to expand the air energy multiple times.

[0013] 5. Different car bodies can adopt different manufacturing schemes. A car can be directly used for power generation after being accelerated once with a section of acceleration unit channel; while another car can be designed to have several acceleration unit channels working together to form multiple rows and sections of airflow channels. The airflow is used for power generation after being accelerated and inhaled multiple times. Even the same car can adopt different schemes in different parts, such as the attached Figure 2 The top section (101) to (109) of the vehicle shown in the figure includes three sections of accelerating unit channels, forming a double jet phenomenon, and adopts a solution of multiple sections of accelerating unit channels docking multiple times to expand energy; while the side of the vehicle uses two sections of accelerating unit channels (110) to (114) to produce a single jet solution; no matter which one is adopted, it is the content of the present invention.

[0014] 6. The airflow channels around the vehicle body are close to or as close as possible to the vehicle body shell, and the channel shape is similar to the airflow field around the vehicle along the wind direction. As described in the background technology of this article, according to aerodynamics, the state of the air flow field around the vehicle during driving is known. Figure 6 , Figure 7 , Figure 8 The figure shows the external air flow fields of several types of vehicles published in aerodynamics. The device of the present invention is arranged around the vehicle body (101) and is manufactured to be close to the shape of the external flow field of the vehicle body. The airflow flowing inside it is similar to the original flow trajectory, so as to reduce the damage of the new device to the airflow around the vehicle body and reduce the resistance generated.

[0015] 7. The acceleration unit channel and the airflow channel it forms can be a solid channel that is closed on all sides, or a semi-closed channel composed of guide rails, guide vanes, guide plates, etc., or a channel formed by the boundary of the airflow that is guided and accelerated. This is because it is not just the air in the flow channel that is involved in power generation, but the entire atmospheric flow field around the vehicle; one of the key technologies of the present invention is energy expansion, which requires the inhalation of new surrounding air, which requires connection with the outside world. Since high-speed airflow will not diverge in the air, regardless of whether the channel is closed or not, it will flow in the direction of guidance and will also produce its own boundaries. Figure 4 In the embodiment, the section (105) to (107) in the channel is composed of two upper and lower guide plates (106-1) and (106-2), and the two sides are not closed. As the distance between the two guide plates gradually decreases, an acceleration channel can be formed, which is in line with the scientific principles described in this article; and the airflow ejected from the outlet is an invisible but existing channel formed entirely by its own boundaries.

[0016] 8. The channel structures of each acceleration unit may be different or the same, and the flow cross-sectional areas of each component may be different. Its several outlets, such as (104), (107), (112) and the wind turbine inlet (201) in the figure, may adopt any type of nozzle, valve, orifice, tube, combined nozzle, orifice plate, gap, or component with reduced flow cross-sectional area. This is because air has no shape, is easy to compress and expand, and its flow trajectory is changeable. Many theories related to gas do not have shape requirements, such as Bernoulli's equation and ideal gas state equation. Although automobile aerodynamics is related to shape, this is due to the different appearance designs of different vehicles; it is precisely because the appearance of vehicles varies greatly, and the present invention can be applied to any vehicle with sufficient installation space, that the shape cannot be restricted. The acceleration unit channel is formed only by the characteristics of increasing wind speed by reducing the flow cross-sectional area in the channel and jetting the outlet wind higher than the surrounding wind speed; the overall shape of the airflow channel around the vehicle body is approximately close to the surrounding flow field of the vehicle body shell; no matter the shape of the flow channel is slightly abruptly reduced or gradually reduced or has parts of equal area straight through or curved, it is only a matter of the shape of the flow channel being close to the original airflow field or a little different; and the channel must be reduced and opened to absorb air, it is impossible to only pursue extreme similarity in shape and airflow field; different car models have different aerodynamic characteristics, and the flow field shapes generated around them are also different. Even for the same car, the flow field shape will change at different speeds; therefore, the shape of the airflow channel cannot be fixed; no matter what type of car model it is, as long as the vehicle speed is generated and the airflow channel is made to meet the characteristics required by the present invention, it conforms to the above theory and can achieve the effect of the present invention. Similarly, the shape and form of the outlet of the present invention cannot be restricted; taking the nozzle as an example, the outlet of the present invention may be installed with a nozzle or not; there are many types of nozzles, with profound professional technology, their functions and effects have been made public, and there are national standards and other standards; the content of the present invention is to set the function of the nozzle, rather than to invent a new nozzle, so no matter what kind of nozzle is used in the present invention, it is the overall technology of the present invention that ultimately achieves the effect.

[0017] 9. Accessories are arranged inside or outside the airflow channel to control the wind direction, change the wind speed, inhale more air, heat the air, and measure the speed, pressure or temperature of the airflow. Accessories include various valves, guide rails, guide vanes, turbines, heating equipment, tachometers, pressure gauges, and thermometers. The present invention can choose to install one or more accessories, or not install any accessories. The use of wind energy is not only to increase the wind speed, but also to control the wind direction and guide the trajectory of the airflow; it is also necessary to measure the wind speed, air pressure, and temperature; in order to achieve the requirements of increasing production capacity, controlling airflow or mastering the airflow conditions, the content of the present invention includes adding one or more accessories, or not adding any accessories. Taking heating as an example, in the north, ice and freezing in winter require heating of the bearings for the rotation of the wind wheel, while in the south, there is no need to install heating components; if heating is used, according to the ideal gas state equation, there is also the effect of producing gas expansion, and eventually part of the thermal energy will also participate in the conversion to electrical energy. Regardless of whether the heater is installed near the bearing or somewhere in the flow channel, the final result of warming the bearing and expanding the gas is the effect achieved by the present invention, and this effect can obviously be achieved by any heater; therefore, the content of the present invention is the result of heating on the device, not what kind of heating or what type of heater. For another example, choose to add valves, turbines or guide rails; obviously, the valve and turbine technology in the world today is developing rapidly, and there are countless types, but the content of the present invention is that they add the function of controlling the airflow in the device, rather than inventing new valves, new turbines or guide rails; therefore, the present invention uses various accessories just like bolts and nuts, and can use national standard parts or non-standard parts. The present invention only needs the tightening function, and the present invention cannot lose protection because of the use of new bolts. Of course, if the present invention does not use or uses less any accessories, it can achieve the effect of increasing wind energy, which is also a case of the present invention.

[0018] 10. Any outlet of the airflow channel can be connected to a wind turbine for power generation. The wind flowing out of any outlet of the airflow channel is accelerated airflow, which already contains expanded wind energy and can be used to generate electricity; the wind from different outlets only differs in the amount of energy increase, but no matter how much, the effect of increasing wind speed for power generation is achieved. The airflow is guided into the direction and position of the wind turbine, and the direction and position of the wind force F that impacts the impeller are used to balance and reduce the adverse forces and moments during the driving of the transportation vehicle, including but not limited to decomposing the wind force into a component force in the same direction of travel to reduce wind resistance. This is the application of automobile aerodynamics to guide the airflow, including adjusting the direction of the airflow force, and when the wind force finally impacts the wind wheel, the force balance and decomposition theory is applied to balance and reduce the adverse forces and moments generated by the vehicle during driving. For example, the component F1 of the wind force F on the y-axis is consistent with the forward direction, which can balance some wind resistance. The present invention also supplements the problem of generating electricity against the wind described in the background technology of this article.

[0019] 11. Install the wind turbine set at the rear of the vehicle and use the airflow separated from the rear of the vehicle to generate electricity. Install the wind turbine at the position where the airflow rotates after leaving the vehicle body, set a bend (13) along the flow field at the rear of the vehicle shell, and the airflow rotates in the bend (132) before entering the wind turbine and then enters the outlet (133), which is the wind turbine inlet (201); the bend (13) can be a curved pipe, a guide rail, or a curved plate. The main theoretical basis of this invention is automobile aerodynamics, with reference to Figure 6 , Figure 7 , Figure 8 It is the flow field shape published by aerodynamics, which clarifies the flow trajectory of different models of airflow after separation and rotation behind the car. The present invention sets a curve based on this trajectory to introduce wind power into the wind turbine for power generation, so as to reduce the energy loss caused by changing the wind direction and solve the problem of generating electricity against the wind. In addition, the present invention installs the wind turbine set at the back of the car without increasing the positive projection area, which solves the problem of installing the wind turbine on the roof described in the background technology of this article; according to automobile aerodynamics, the size of the positive projection area of ​​the car is one of the factors that determine the size of wind resistance. If the generator is installed on the roof, the positive projection area is increased, which means that the wind resistance is increased. The wind turbine set of the present invention is installed at the back of the car, and does not generate a positive projection area, and will not increase wind resistance; at the same time, it also solves the problem of the deflection force generated by the unidirectional rotation of the wind wheel.

[0020] 12. Differences from the reference invention technology. The technical content of Chinese patent application No. 202310101075.8 is introduced in the background technology of this article. The difference between this invention and the present invention is that this invention forms air with a pressure higher than that of the atmosphere in the flow channel; the core basis of production capacity is the compressor theory, forming four working processes, completing the compressor function, and being able to repeat the compression process step by step to achieve multi-stage compression; the key to this invention is the process of converting speed into pressure, that is, pressurized air, which means that the wind speed must be reduced and the speed energy must be converted into pressure energy, which requires the channel to be closed, otherwise the airflow will diverge. Of course, this invention is converted into speed energy again at the outlet due to acceleration pressure, so the outlet produces a jet but is not closed. The difference between this invention and this invention is that no compressed air is generated in the flow channel, the present invention does not have the function of a compressor, and the present invention only uses acceleration or continuous acceleration to expand wind energy, so the airflow itself will not diverge, and the channel does not have to be closed. These two technologies are two theoretical bases and inventions with different technical natures. In essence, the air flow channel of the invention is a compressor, and the present invention is an accelerator. Therefore, the two have their own advantages due to different production principles, production methods and device structures.

[0021] 13. The overall effect of the present invention is to utilize wind energy while the vehicle is traveling; it generates electricity while driving to supplement the energy consumption of the vehicle. The total energy used to drive the wind wheel of the present invention includes the energy of wind resistance plus the energy of new air absorbed. It is not the wind resistance energy that is used to generate electricity to supplement the energy consumption of the vehicle, but the new air energy converted into wind energy by the present invention, which is the energy generated by the new air absorbed through the jet and Venturi effect; the wind resistance energy is only the recovered energy consumed by the vehicle, which comes from the power of the vehicle.

[0031] The air flow channel (10) includes a vehicle body (101), an inlet (102), an acceleration section (103) with a reduced flow cross-sectional area, an outlet (104), and the like (105) to (107), (108) to (109), (110) to (114), a curve (13) section, etc.

[0033] The bend (13) section includes an inlet (131), a bend (132) where the airflow turns and changes direction, and an outlet (133) connected to the wind turbine inlet (201). DETAILED DESCRIPTION

[0034] 1. Implementation method 1: Figure 1 As shown, a complete set of devices of the present invention includes an airflow channel (10) and a wind power device (20). A row of airflow channels are installed on the roof of the vehicle. The airflow on the roof is accelerated by a section of an acceleration unit channel and then enters the wind turbine behind the vehicle. The working process is to manufacture and install an acceleration unit channel on (101). The wind entering the inlet (102) gradually decreases in the airflow channel (103) due to the shrinkage of the channel flow cross-sectional area, and the flow velocity gradually increases. Because it is directly connected to the bend (13) to turn the airflow direction, the outlet (104) coincides with the inlet (131) of the bend (13). Therefore, Figure 1 The positions of the outlet (104) and the inlet (131) are not marked; and the bend (132) is also an acceleration unit channel with a reduced flow cross-sectional area. The airflow on the roof changes direction through the bend (13) and accelerates at the same time, and passes through the outlet (133) to connect to the wind turbine inlet (201) for power generation. The airflow on the side of the car also changes direction through the bend to generate power using the airflow separated from the car body behind the car. This embodiment shows the basic component for increasing wind speed, the acceleration function of the acceleration unit channel. According to the Bernoulli equation, the wind in the acceleration unit channel increases in velocity due to the reduction in cross-sectional area; a Venturi effect is generated; and behind the car, according to the theory of automobile dynamics, the airflow direction is turned according to the flow field at the rear of the car.

[0035] 2. Implementation method 2: Fig. 9 As shown, the present invention separates and connects the outlet (104) and the inlet (131) of the first embodiment, generates a jet energy expansion here, brings in new air, and utilizes the aerodynamic characteristics of the airflow leaving the vehicle body at the rear of the vehicle to enter the wind turbine for power generation. The rest of the structure of this device is the same as that of the first embodiment.

[0036] 3. Implementation method three: Figure 2As shown, another complete set of devices of the present invention is formed by connecting three sections of accelerating unit channels on the roof of a vehicle to form a row of three sections of airflow channels; the method and principle of accelerating the wind in the sections (102) to (104) are the same as those in the first embodiment, and then the wind is ejected from the outlet (104) of the first section at a higher wind speed than the surrounding wind speed, and then enters the entrance (105) of the second section channel. Here, according to the jet theory, the gas flows out through small holes, gaps, etc. at a certain speed, and a boundary airflow will be formed within a certain distance, and its boundary will remain unchanged when flowing in a certain direction; therefore After the airflow flows out (104), it all enters the entrance (105) of the next channel. At the same time, the suction drives more surrounding air to flow together and enter the entrance (105) of the next channel. This is to expand the wind energy. After being accelerated again in the channel (105) to (107) with a gradually reduced flow cross-sectional area, it is ejected from the second section outlet (107) at a wind speed higher than the surrounding wind speed. This is the second acceleration section. Similarly, the airflow from the outlet (107) enters the next channel through the inlet (108). The side of the vehicle adopts three rows and two sections of airflow channels. The shape and composition of the roof and the side airflow channels of this method can be different, but the side airflow process is the same as the roof. The wind turbine of this device is the same as the first and second embodiments. It is installed at the rear of the vehicle, turned around, and uses the airflow characteristics of the rear of the vehicle to generate electricity in the rotating direction.

[0037] 4. Implementation method 4: Figure 3 As shown, it is another complete set of device products of the present invention, in which 9 sections of accelerating unit channels are organized into 3 rows and 3 sections of airflow channels on the roof; the inlets (102), (102-2), and (102-3) are distributed as the first section inlets of the three rows of airflow channels, and then each leads to a row of airflow channels, and its accelerated airflow work process is analogous to the third embodiment; the rest of the structure of this device is the same as the third embodiment.

[0038] 5. Implementation method five: Figure 4 As shown, a device of the present invention is compared with the original vehicle body air flow field, and the air flow channel includes all parts through which the roof airflow flows to the generator, that is, including the pipe sections (105) to (107), (108) to (109), and (132) to (133). Figure 6 , Figure 7 , Figure 8 The airflow fields outside several types of vehicles are derived from the book "Automobile Aerodynamics" (written by Fu Limin). Although the flow fields around various types of vehicles are different, the aerodynamic properties are the same. The airflow channel of the present invention is set to fit the vehicle body shell as closely as possible, and its shape is similar to the aerodynamic flow field outside the vehicle. The airflow flowing inside it is similar to the original flow trajectory, so as to reduce the damage of the device to the airflow around the vehicle body and reduce the resistance. The rotating airflow channel behind the vehicle is the flow field shape that all types of vehicles will produce. According to the reference Figure 6 , Figure 7 , Figure 8As shown, on the original vehicle body, at the location of the wind turbine of the present invention, even if a solid channel is not provided, the airflow will enter the wind turbine at this location. Therefore, it is an achievable invention. The 106 section in this case is not a closed pipe section, but an airflow channel formed by a channel composed of two guide plates (106-1) an upper plate and (106-2) a lower plate. As the distance between the two plates gradually decreases, the flow cross-sectional area also gradually decreases, which accelerates the airflow in the channel.

[0039] 6. Implementation method 6: Figure 5 As shown, in this case, the wind turbine is installed at the rear of the vehicle, and the wind from the airflow channel on the roof is guided to push the wind wheel in the direction of wind force F. When the wind acts, a component force F1 in the same direction as the driving direction is decomposed on the x-axis to reduce wind resistance.

[0040] 7. Implementation method seven: Fig.10 As shown, it is another complete set of device products of the present invention. The roof of this device is composed of two sections of accelerating unit channels connected together, and its accelerated airflow workflow is the same as that of the third embodiment; the wind turbine is installed on the roof, and after being accelerated by the two sections of accelerating unit channels (102) to (104) and (105) to (107), the airflow is ejected from the outlet (107) and directly enters the wind turbine for power generation. The wind turbine of this device is installed on the roof, and the airflow does not turn to the back of the car, but directly generates electricity on the roof. This solution is also one of the devices of the present invention, because the wind has been accelerated and expanded by the present invention before entering the wind turbine, and the energy of power generation is higher than that of natural wind.
