Description

  The present invention relates to a wind power generation apparatus suitable for mounting on a moving body such as an automobile, and in particular, wind generated by the movement of the moving body is collected and guided to a windmill, and the generator is rotated by the rotation of the windmill. The present invention relates to a wind power generator that charges a battery mounted on a moving body with the generated power.

In recent years, global warming due to greenhouse gases has become a problem. As greenhouse gases, carbon dioxide (CO ₂ ) generated by cultivating land in forests and burning fossil fuels, methane (CH ₄ ) generated by burning livestock and fossil fuels, fuel combustion and nitrogen fertilizer There are dinitrogen monoxide (N ₂ O), chlorofluorocarbon gas and the like generated by Of these, for carbon dioxide, automakers producing diesel and gasoline vehicles are working on improving fuel efficiency and developing electric vehicles. In particular, since an electric vehicle is effective in reducing carbon dioxide, its rapid practical application is desired. There are a secondary battery (battery) and a fuel cell as a power source adopted for an electric vehicle, and it is said that a fuel cell needs several decades before it is put into practical use. Therefore, the current electric vehicle uses a secondary battery as a power source, but does not have a battery capacity to run the car for a long time, and even an electric vehicle that is being marketed is charged once (80 % Charge) is about 160 km (in the case of 10.15 mode), which is about half the distance of a gasoline car. For this reason, in order to popularize electric vehicles, it is necessary to install charging facilities such as a charging stand in a heavy place in the city, but at present, it is extremely limited.

  In the current situation where infrastructure such as a supply stand is not in place, the driver must check the power meter installed in the vehicle frequently and return to a place equipped with a charger such as home or work to perform charging. Don't be. Since this charging takes, for example, 5 hours or more, a considerable waiting time is required. Therefore, there is a plug-in hybrid system in which a small gasoline engine is mounted on a vehicle and a generator is moved by this engine to charge the vehicle while traveling. However, although this method emits less carbon dioxide than a power engine, it does not change carbon dioxide. Therefore, two long cylindrical ducts are installed on the roof of the vehicle, a small wind power generator is installed so that the wind blows into the cylindrical duct, and the battery is charged while driving with the power obtained by this. There has been proposed a vehicle with a wind turbine generator that can be used (see Patent Document 1).

Japanese Patent No. 2992242

  However, in order to obtain sufficient rotational torque and power generation efficiency with the configuration disclosed in Patent Document 1, a propeller having a size that can be rotated by wind force taken in by a cylindrical duct is required, and power required for a small-sized propeller windmill is required. May not occur.

  In addition, the cylindrical duct mounted on the roof of the vehicle is likely to be subjected to wind pressure such as cross wind, and the running performance may be lowered, which may cause anxiety in safe driving. In addition, when a paddle type windmill is used for the wind turbine generator, the windmill rotates by receiving some of the cup-shaped paddles. In this case, since wind pressure resistance is applied to all paddles that are not receiving wind (that is, paddles that do not contribute to rotation), the rotational torque conversion efficiency is very poor. The main cause is the structure of the windmill. That is, a plurality of paddles are arranged radially independently from the rotating shaft of the windmill, and some paddles rotate when receiving wind, but all of the paddles that do not contribute to rotation have wind pressure resistance. The relative rotational force decelerates because it is applied. For this reason, the rotational conversion efficiency of the rotational torque is very poor.

[Operation of wind turbine generator]
Next, an example in which the operation of the wind power generator 100 described above is applied to an automobile as shown in FIG. 2 will be described. When the automobile 10 is traveling, outside air is taken into the engine room according to the traveling speed, and the engine and cooling water are cooled by air. A part of the outside air taken into the engine room through the grill provided on the front surface of the automobile 10 is also taken into the hood 1 shown in FIGS. When the automobile 10 is traveling at a speed of 60 km / h, an air current having a wind speed of about 16.6 km / sec is generated. Furthermore, an air current having a strong wind speed of 17.7 km / sec at a speed of 80 km / h and 27.7 km / sec at a speed of 100 km / h is generated. By taking such strong wind energy into the hood 1 from the grill in the engine room, the windmill 44 can be easily rotated at a high speed. When power generation by the wind power generator 100 is not required or when the vehicle is parked or the like, the pipe ducts 20A and 20B of the intake air selection mechanism 2 match the bellows pipes 3C and 3D as shown in FIG. The wind collected at is exhausted through the bellows pipes 3C and 3D.

  The vehicle 10 is equipped with a control device (not shown), and this control device has a monitor function for monitoring the storage capacity of a battery mounted on the vehicle 10 by a terminal voltage or the like. When the storage capacity becomes equal to or less than the set value, the control device activates the drive source 26 shown in FIG. 3 to rotate the pinion 25 and raise the rack gear 23, the pipe ducts 20A and 20B, and the hood 1. As shown in FIG. 4, when the pipe ducts 20 </ b> A and 20 </ b> B match the bellows pipes 3 </ b> A and 3 </ b> B, the control device stops the drive source 26. In this state, the wind W1 collected by the hood 1 is supplied to the wind power generators 4A and 4B shown in FIG. 1 through the bellows pipes 3A and 3B. The wind W1 that has reached the air intake port 9a of the case 40 from the bellows pipes 3A and 3B hits the variable blades 46a and 46b as shown in FIG. As a result, the variable blades 46a and 46b open until they abut against the over-opening prevention plate 47. At this time, the angle between the variable blade 46a and the variable blade 46b is about 90 °, thereby forming a pocket for receiving wind. The variable blades 46a and 46b rotate the outer ring hub 42 while maintaining this state. The wind W1 is successively sent to the plurality of wind turbines 44 to continuously rotate the outer ring hub 42 and the generator 41, generating power generation output in the wind power generators 4A and 4B, thereby charging the battery.

  The windmill 44 receiving wind from the bellows pipes 3A and 3B rotates counterclockwise as shown in FIG. 8 along with the rotation of the outer ring hub 42, and moves to the 3 o'clock position of the timepiece as shown in FIG. 56b contacts the semicircular rails 45a and 45b, and the windmill 44 moves in that state. As shown in FIG. 9, the first magnets 52a and 52b attached to the inside of the variable blades 46a and 46b and the magnet holding plate 48 have magnetic poles opposite to the second magnets 53a and 53b. It has become. For this reason, a repulsive force is generated between the variable blades 46a and 46b and the magnet holding plate 48 so as to separate them. Therefore, a force against the magnetic force between the variable blades 46a, 46b and the magnet holding plate 48 is forcibly applied to the variable blades 46a, 46b by the semicircular rails 45a, 45b, and the force between the variable blades 46a, 46b. The angle is about 30 °. At this time, as shown in the wind turbine 44 on the right side of FIG. 7, spaces 61 a and 61 b are formed between the variable blades 46 a and 46 b and the case 40, so that the semicircular rails 45 a and 45 b are provided. As shown in FIG. 10, the wind pressure resistance that brakes the rotation of the windmill 44 through which the wind W2 (see FIG. 10) on the back surface of the variable blades 46a and 46b passes is reduced.

  When the rotation of the windmill 44 proceeds and the roller bearings 56a and 56b finish passing through the semicircular rails 45a and 45b shown in FIG. 8, the magnetism between the first magnets 52a and 52b and the second magnets 53a and 53b. The variable wing 46a and the variable wing 46b are opened so as to be separated by the repulsive force, and the state shown in FIG. 9 is restored. Thus, preparations for receiving wind from the bellows pipes 3a and 3b are completed.

  It should be noted that a wind reverse flow, Karman vortex, or the like is generated with respect to the wind turbine 44 at the joint portion between the case 40 and the exhaust ducts 6a and 6b. In order to eliminate this, a duct hose 7 and a wind collecting duct 8 are provided. The strong wind taken from the air collecting duct 8 is supplied to the joint portion between the case 40 and the exhaust ducts 6a and 6b via the duct hose 7, thereby eliminating the backflow and Karman vortices.

  By the way, the automobile 10 stops at a red signal during traveling, and is forced to decelerate and drive slowly in a traffic jam section. In such a case, there is no wind except when the wind is strong, but since the flywheel 28 is provided, the wind turbine 44 will function for a while by rotating the wind turbine 44 by inertia, but the wind turbine 44 will eventually stop. Will do. However, since the wind turbine generator 4A is provided with the wind turbine rotation auxiliary means 70, the wind turbine 44 does not stop. That is, when the internal pressure of the air tank 74 becomes a predetermined value or less, the compressor 71 is operated, and thereby air is pressed into the air tank 74.

  When the sensor 75 detects that the motor vehicle 10 has been decelerated, driven slowly, and stopped, and the rotational speed of the windmill 44 has become equal to or lower than the predetermined rotational speed, the solenoid valve 70 is activated, and the nozzle 71 and the piping 73 Communicate. As a result, the air in the air tank 74 is discharged to the nozzle 71. By injecting air from the nozzle 71, the injected air is blown to the variable blades 46a and 46b facing the air intake port 9a for a predetermined time instead of the air from the bellows pipe 3A. By moving 46b, the windmill 44 begins to rotate, and the rotational speed further increases. As a result, electric power for charging the battery is secured. Further, after a predetermined time, when the sensor 76 detects again that the windmill 44 is insufficiently rotated, the electromagnetic valve 72 is operated, air is ejected from the nozzle 71, and the rotation of the windmill 44 is accelerated. Thereafter, when the automobile 10 is in a normal running state, wind sufficient to rotate the windmill 44 is discharged from the bellows pipe 3A, and there is no need to inject air from the nozzle 71. Therefore, the solenoid valve 72 does not operate until the automobile 10 is decelerated and stopped.

[Effect of the first embodiment]
According to the wind turbine generator according to the first embodiment, there is an effect that the influence of the cross wind can be reduced by collecting the wind with the hood 1 and making it one place of the air intake 9a that blows the wind turbine 44. is there.
Further, the variable blades 46a, 46b are combined in a "<" shape with variable opening, and the mutual opening between them is generated between the first magnets 52a, 52b and the second magnets 53a, 53b. The windmill 44 is configured so as to be opened at about 90 ° by force to form a pocket, the wind from the hood 1 is received in this pocket and the outer ring hub 42 is rotated. When the variable blades 46a and 46b are pushed into the outer wheel hub 42 side by the semicircular rails 45a and 45b, the wind pressure resistance against the wind turbines 44 and 44 not receiving wind is reduced, thereby rotating. There is an effect that efficiency and power generation efficiency can be increased.
Further, the intake selection mechanism 2 is provided between the hood 1 and the wind power generators 4A and 4B so that the wind turbine 44 is supplied with wind only when necessary, thereby extending the life of the generator 41 and the wind turbine 44 and rotating the wind turbine 44. There is an effect that the noise of the vehicle can be reduced by making no sound.
Further, by providing a windmill rotation auxiliary means 70 including a nozzle 71, a solenoid valve 72, a pipe 73, an air tank 74, a compressor 75, and a sensor 76, the automobile 10 is decelerated and stopped, and wind is collected into the wind collecting duct 8. There is an effect that the rotation of the windmill 44 can be continued even if it cannot be taken in.

2. Second Embodiment FIG. 16 is a plan view showing a second embodiment of a wind turbine generator according to the present invention, FIG. 17 is a plan view showing the inside of a lid that covers the wind turbine generator of FIG. 16, and FIG. 18 is variable. FIG. 19 is a side view showing a state in which the blade has the maximum opening, and FIG. 19 is a side view showing a state in which the variable blade has the minimum opening. 16 and 17, the illustration of the solenoid valve 72, the pipe 73, the air tank 74, the compressor 75, and the sensor 76 is omitted. In this embodiment, the magnet holding plate 48 is removed in the first embodiment, the shape of the tip of the variable blades 46a, 46b is changed, and the mounting location of the first magnets 52a, 52b, 53a, 53b is changed. Other configurations are the same as those of the first embodiment. That is, in the present embodiment, the tips (free ends) of the variable blades 46a and 46b are bent to form magnet attachment portions 462a and 462b, and the second magnets 53a and 53b are attached to the magnet attachment portions 462a and 462b. A plurality of (eight in this case) first magnets 52a, opposite to the trajectory through which the second magnets 53a, 53b pass (the lines where the semicircular rails 45a, 45b are provided in the first embodiment). 52b is attached to the inner surface of the lid 401 of the case 40 and the bottom surface of the main body 402 at equal intervals. The magnetic poles on the opposite sides of the second magnets 53a and 53b and the first magnets 52a and 52b have different combinations almost every half circumference as shown in FIG. Specifically, the first magnets 52a and 52b located approximately half a circumference in the rotation direction from the attachment position of the bellows pipes 3A and 3B are set as S poles, and the remaining first magnets 52a and 52b located approximately half a circumference are defined as N. I am at the pole. On the other hand, the second magnets 53a, 53a, 53b, 53b are all S-poles.

  Next, the rotation operation of the wind turbine generator according to the second embodiment described above will be described. When the strong wind W1 is blown against the wind turbines 44 and 44 of the wind power generators 4A and 4B facing the bellows pipes 3A and 3B, the variable blades 46a and 46b are opened as shown in FIG. The windmills 44, 44 move in the right direction shown in FIG. 18, and the outer ring hub 42 rotates accordingly. At this time, the first magnets 52a and 52b and the second magnets 53a and 53b are attracted to each other because the N pole and the S pole are opposed to each other, and the variable blades 46a and 46b are kept open. In this state, when the outer ring hub 42 is substantially half-turned, the S-pole second magnets 53a and 53b reach positions facing the S-pole first magnets 52a and 52b. Then, due to the S poles, the second magnets 53a, 53b and the first magnets 52a, 52b are magnetically repelled to generate a magnetic force in the direction of closing the variable blades 46a, 46b. Since there is no moving wind force, the variable blades 46a and 46b are in a horizontal state as shown in FIG. At this time, as shown in FIG. 19, since spaces 61a and 61b are formed between the variable blades 46a and 46b and the case 40, the windmill passes through the installation range of the first magnets 52a and 52b having N poles. Wind pressure resistance acting to brake the rotation of 44 is reduced. When the windmills 44 and 44 pass through the installation range of the first magnets 52a and 52b having N poles, the first magnets 52a and 52b facing the second magnets 53a and 53b become S poles. Therefore, the tips of the variable blades 46a and 46b are attracted to the first magnets 52a and 52b, and pockets are formed by the windmills 44 and 44 as shown in FIG. 18, so that the wind from the bellows pipes 3A and 3B can be received. The outer ring hub 42 can be rotated.

[Effect of the second embodiment]
According to the wind turbine generator according to the second embodiment, the variable blades 46a and 46b can be opened and closed by the combination of the magnetic poles of the first magnets 52a and 52b and the second magnets 53a and 53b. The rails 45a and 45b and the roller bearings 56a and 56b are not required, and the configuration can be simplified and the cost can be reduced by reducing the number of parts. Other effects are the same as those of the first embodiment.

  As described above, the preferred embodiment of the present invention has been described in detail. However, the present invention is not limited to the specific embodiment, and within the scope of the gist of the present invention described in the claims, Needless to say, various modifications and changes are possible.

  For example, instead of the roller bearings 56a and 56b, the rotational frictional resistance can be reduced even with a configuration using a thin and light hard ceramic plate.

  In addition, the wind power generator 100 is configured by two wind power generators 4A and 4B, but may be one or more than two. Further, although the wind power generators 4A and 4B rotate the outer ring hub 42 in a horizontal arrangement, both of them can be arranged vertically or diagonally, or can be arranged in a V shape. Further, one of the wind power generators 4A and 4B can be arranged horizontally and the other can be arranged vertically, or the wind power generator 4A and the wind power generator 4B can be installed at a remote location.

  The wind power generator 100 according to the present invention is optimally mounted on a moving body such as an automobile that can generate a strong wind by traveling. However, the wind power generation apparatus 100 is a place where a strong wind can be obtained or the opening area of the hood 1. By increasing the number of wind power generators 4A and 4B, it is possible to install them in non-moving facilities, structures, and the like.

  The air introduced into the windmills 4A and 4B via the duct hoses 7A and 7B is taken from the wind collecting duct 8, but for example, air branched from the bellows pipes 3A and 3B is introduced into the duct hoses 7A and 7B. May be.
