Those skilled in the art will understand the specific meanings of the above terms in the utility model according to specific circumstances.As shown in FIGS. 1-2, the power generation apparatus for converting air resistance into electric power using a compressed air duct includes an air duct housing 1, an impeller 2, and a generator 3.The air duct housing 1 has a compressed air duct 6, one side of the compressed air duct 6 is an air inlet 4, the other side is an air outlet 5. The impeller 2 rotates and is located in the compressed air duct 6, and the generator 3 is connected to the impeller 2.This device can be installed in new power vehicles and other transportation means. The higher the speed, the greater the drag experienced by a new energy vehicle. Therefore, when this apparatus is installed, the air flows into the compressed air duct 6 through the air inlet 4, is then pressurized by the natural shape of the compressed air duct 6, and then blows toward the impeller 2, thereby rotating the impeller 2, and finally flows out from the air outlet 5.As the impeller 2 rotates, it drives the generator 3 and generates power. The power generated by the generator 3 can supplement the power consumption of these vehicles. Therefore, the apparatus can exploit and convert the air resistance that these vehicles cannot overcome in forward driving into electricity that can be utilized by the vehicles. This saves energy and protects the environment.In the apparatus, the air in the air duct housing 1 is not pressurized by an additional driving device, but only by the shape of the compressed air duct 6 itself, so that no additional energy consumption occurs during the pressure increasing process.The air duct case 1 can increase the flow rate of the air by pressurizing the air so that the rotation speed of the impeller 2 is higher when the air hits the impeller 2 and rotates it, which contributes to improvement in the efficiency of power generation. In actual use, as shown in FIGS. 1 and 2, the compressed air duct 6 along the direction from the air inlet 4 to the air outlet 5 is a constriction air duct.The impeller 2 being an axial impeller 2 or a centrifugal impeller 2. For example, in FIG. 1, the impeller 2 is an axial impeller 2, and the air flows along the axial direction of the impeller 2, impinges on the impeller 2 and drives the impeller 2 to rotate. The generator 3 used is an ordinary permanent magnet generator 3, and at this time, the apparatus as a whole has a funnel-shaped structure. In FIG. 2, the impeller 2 is a centrifugal impeller 2, and the air flows along the circumferential direction of the impeller 2, impinges on the impeller 2, and drives the impeller 2 to rotate. The generator 3 used is a disc-shaped permanent magnet generator 3 and the device as a whole currently has a helical shell structure. Of course, this device can also be constructed in other forms, in this case have not restricted designs.And, between the rotating shaft of the impeller 2 and the input shaft of the generator 3, gear structures such as chain drive and gear drive may be disposed according to the actual situation, so that the impeller 2 can drive the generator 3 for power generation, which is a conventional technology and will not repeat.As shown in FIGS. 3 and 4, hereinafter, this device installed on the new power vehicle is taken as an example to explain the operation principle of this device in detail.There are three main types of drag to which the vehicle is exposed during travel: first, the enormous drag caused by the air flow striking the front of the vehicle; the second is a relatively low frictional drag; the third is the dimensional stability with relatively little impact. In order for a vehicle to travel quickly, it requires more energy to overcome this impact resistance. In comparison, it is equivalent to strong air currents, and the larger the area of the vehicle head, the larger the resistance.On this basis, as shown in FIGS. 3 and 4, in use, the apparatus needs to be installed at the front of a vehicle with new power. In this case, the air flow from the front side of the vehicle can pass through the windshield of the vehicle into the compressed air duct during travel, be collected there and be conducted to the running wheel, whereby the generator can generate power. In this way, the resistance of the frontal impact of the gas that the vehicle cannot get off can be converted into electrical energy, so that the energy that the vehicle consumes to overcome the frontal resistance is converted into new electrical energy available to the vehicle. This helps to increase the endurance of the vehicle.Specifically, the device can use the convergent shell to guide the impact resistance of the front of the vehicle precisely on the impeller of the generator. When the air flow encounters the vanes, it is discharged evenly from the end airway opening. It is noteworthy that the vertical area in which the airflow impinges on the casing (a portion of the rotor blades) is significantly smaller than the area in which the airflow impinges on the front of the vehicle, and that most of the impact resistance is converted to lateral frictional resistance in a skillful manner. Moreover, the impact resistance is immediately converted into frictional resistance as the rearward inclination angle of the rotating blades gradually increases. This process significantly optimizes the energy conversion path and fully reflects the sophisticated concept of the application for resistance conversion.The energy storage wheel installed on the impeller causes a geometric increase in the force absorbed by the impeller under the double action of centrifugal force and inertial force, enables maximum conversion of shock resistance into performance, and significantly improves the efficiency of energy conversion.The housing of the device is basically a tubular structure. As the air flow passes through the housing, a narrow tube effect is created which effectively reduces drag and further optimizes the guidance and utilization of the air flow.Driven by such a strong air flow, the impeller can generate an enormous torque, which in turn drives the generator, so that it operates efficiently and generates current. Take as an example a family car equipped with a 10 kW permanent magnet generator with disc magnetic levitation trains (depending on the need of the vehicle, a device with a power adaptation of 5-20 kW can be installed). At high speed (over 80 km / h), up to 10 kW / h of current per 100 kilometers can be obtained, which can substantially increase the range of the vehicle and substantially extend the deployment radius and application scenarios of alternative energy vehicles.In summary, this device utilizes aerodynamics, flow effects and the storage of inertial energy in a scientific and rational manner, so that the drag it imparts substantially corresponds to the impact resistance of the front of the vehicle and thus does not result in an obvious additional energy consumption.This device makes reasonable use of the principles of aerodynamics, flow effects and the technology for storing inertial energy, so that the air resistance of the device corresponds substantially to the impact resistance of the vehicle front. There is therefore no apparent additional power consumption, but it converts the original resistor into power in a skillful manner and thus enables efficient energy recovery and re-use. This device provides a new solution to the energy management and improvement of the life of new energy vehicles and is highly innovative and practical.Although the embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations can be made in the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
