Description

  The present invention relates to a wind power generator that is mounted on a moving body such as an electric vehicle and charges a battery or is fixedly installed on the ground side to generate electric power, and a mobile body on which the wind power generating apparatus is mounted. The present invention relates to a wind power generation device that reduces wind pressure resistance of a blade and enables rotation even in a weak wind, thereby improving power generation conversion efficiency, and a moving body equipped with the wind power generation device.

  In recent years, global warming caused by greenhouse gases has become a global problem. In particular, the existence of automobiles that run on fossil fuels such as gasoline and light oil that generate carbon dioxide has become a problem, and electric cars that do not generate carbon dioxide and hybrid cars that can reduce carbon dioxide have attracted attention. Although an electric vehicle uses a secondary battery as a power source, at present, battery capacity sufficient to run the vehicle for a long time is not obtained, and frequent charging is required. In the current electric vehicle, the charging time of the on-board battery (secondary battery) is, for example, 14 hours or more (when using a 100 V household power source). Therefore, in order to widely spread electric vehicles, it is necessary to install infrastructure facilities such as charging stations in various places like conventional gas stations, but the number of installations is extremely limited at present.

  Therefore, in the current situation where infrastructure facilities such as a charging stand are not in place, it is inappropriate to use an electric vehicle for long-distance travel. In addition, the driver is required to drive while frequently checking the electric capacity meter (or remaining capacity indicator) of the electric vehicle, and needs to know where the charging equipment is provided. Therefore, as a means for eliminating or reducing such inconvenience, an electric vehicle with a wind power generator in which a solar panel or a wind power generator is mounted on a roof has been proposed (for example, see Patent Document 1). Furthermore, a system in which three types of power generation means, that is, a solar power generation device, a wind power generation device, and a multi-blade blade wind turbine are mounted on the roof of a vehicle has been proposed (for example, see Patent Document 2).

It is fixed not to.

  FIG. 4 is an exploded perspective view showing details of the windmill mechanism 8. The windmill mechanism 8 generally includes an upper rotating plate 13 having a rotating spindle MS attached at a disk-shaped center position, a plurality of bearings 14 and 14 disposed on the surface of the upper rotating plate 13 at predetermined intervals, A ring flywheel 15 attached to the periphery of the upper rotating plate 13 to increase inertia, a donut-shaped lower rotating plate 19 in which a portion where the generator AN and the fixed inner ring cylinder 10 are located is a space, and a lower rotating A plurality of bearings 25, 25 arranged on the surface of the plate 19 at a predetermined interval, a ring flywheel 18 attached to the periphery of the lower rotary plate 19 in order to increase rotational inertia, the upper rotary plate 13 and the lower rotary plate A cylindrical rotating body 17 which is disposed and fixed at a substantially center between the rotating inner cover 19 and covers the fixed inner ring cylinder 10 from the outside, and an upper rotating plate 13 and a lower rotating plate 19 provided on the rotating body 17. Non-magnetic bolt holders 24, 24 holding a plurality of (here, five) bolts 23, 23, and rotating shafts 21, 21 supported by bearings 14, 14 and bearings 25, 25 A plurality of retractable wings 20, 20 that can be freely rotated (about 90 °) and are curved in a bow shape (five in this embodiment, but one in front is not shown in FIG. 2); The magnets 22, 22 attached to the wind receiving surfaces of the tiltable blades 20, 20 and the tiltable blades 20, 20 placed in a standing position in the vicinity of the peripheral portion on the inner surface side of the upper rotating plate 13. Non-magnetic windmill stopping members 16 and 16 for stopping or positioning the rotation of the rotating blades 20 and the falling blades 20 and 20 which are arranged at predetermined intervals in the vicinity of the peripheral portion on the inner surface side of the lower rotating plate 19 and are in an upright state. Stop or position 40, 40 of nonmagnetic material to be processed. The rotation main shaft MS is connected to a rotor (not shown) of the generator AN, and the rotation main shaft MS is rotated by the retractable blades 20 and 20 that have received the wind, so that the rotor is rotated and the generator AN generates power. To be done. The electric power generated by the generator AN may be used as it is, or the battery or the rechargeable battery can be charged. The generator AN and the fixed inner ring cylinder 10 are arranged in a space portion of the lower rotary plate 19 formed in a donut plate shape, and are not rotated by the rotation of the lower rotary plate 19.

  The retractable blade 20 is provided with a rotating shaft 21 on the base end side thereof, and the rotating shaft 21 is supported by a bearing 14 and a bearing 25 disposed between the upper rotating plate 13 and the lower rotating plate 19, respectively. Thus, the rotary shaft 21 is attached so as to be rotatable. As shown in FIGS. 2 and 4, a corrugated groove 27 is provided in the entire area of the wind receiving surface that is the surface on which the wind strikes, and is formed so as to efficiently receive the wind from the wind collecting hood 3. The magnets 22 and 22 attached to the retractable blade 20 are attached so that the groove 27 side is the S magnetic pole and the opposite side is the N magnetic pole. Further, the magnets 11 and 11 are arranged so that the rotation main axis MS side is an S magnetic pole, and the magnets 12 and 12 are arranged so that the rotation main axis MS side is an N magnetic pole. Although the magnets 22 and 22 can be reversed in polarity, in this case, the magnets 5A, 5A, 5B, 5B, 11, 11, 12, and 12 must all be reversed. The retractable blade 20 rotates smoothly with the frictional resistance and the like significantly reduced by the bearing 14, the bearing 25, and the rotating shaft 21, and stands up in the space from the air collecting hood 3 side to the air discharge port 4. In the other space 28, the surface of the rotating body 17 is laid down. The bearings 14, 14, 25 and 25 are preferably ball bearings having as little resistance as possible. In addition, it is preferable that each member which comprises the wind power generator 100 is formed with a nonmagnetic material except magnets 5A, 5B, 11, 12, and 22.

  FIGS. 5A, 5 </ b> B, and 5 </ b> C are perspective views showing other examples of the retractable blades 20 and 20. All of them are devised to increase the wind receiving efficiency. FIG. 5A shows an example in which a groove 27 on the surface side for receiving wind is provided at right angles to the direction of the rotation axis 21 and the wind receiving surface is formed in a wave 34 shape, and FIG. An example in which the groove 27 is provided in the same direction as the direction of the rotating shaft 21 opposite to the retractable blades 20 and 20 in FIG. 4 and each groove shape is an inverted V shape, FIG. This is an example in which quadrangular pyramidal projections 35 are provided at predetermined intervals. The reason why the wind receiving surface has such a shape is that the wind (air) contact area is increased so that the wind can be accurately captured even on a small wind force.

  The wind power generator 100 described above can be mounted on a moving body such as an automobile, a ship, a train, and an aircraft. In other words, by mounting on a moving body that uses electric power, it is possible to reduce hydrogen fuel when using a fuel cell as well as gasoline, and greatly contribute to energy saving by reducing the number of times the battery is charged. .

[Operation of Wind Power Generator 100]
Next, operation | movement of the wind power generator 100 mentioned above is demonstrated. The wind power generator 100 mounted on a moving body such as an automobile takes in outside air from the wind collecting hood 3 when the moving body starts moving and reaches a predetermined speed. At this time, in the ventilation path 29 extending from the air collecting hood 3 to the air discharge port 4, the retractable blade 20 positioned in the ventilation path 29 is rotated in a direction in which the tip approaches the inner peripheral surface side of the outer case 1 by wind pressure ( That is, it stands up with respect to the rotating body 17, and in this state, the rotating body 17 also rotates at the same time so that the ventilation path 29 is fully developed. Further, the retractable blade 20 reaching the ventilation path 29 is restricted from further rotation by the wind turbine stopping members 16 and 40 provided on the upper rotating plate 13 and the lower rotating plate 19, as is apparent from FIG. 2. In addition, the retractable blades 20 and 20 interposed in the ventilation path 29 receive the wind from the wind collecting hood 3 on the entire surface on the groove 27 side. Therefore, the rotating body 17 receives a strong rotational force.

  The retractable blade 20 receiving the wind moves in the ventilation path 29 in the outer case 1 while rotating the rotating body 17. Further, in the process in which the retractable blade 20 continues to rotate, the north pole of the magnet 22 of the retractable blade 20 faces the north pole of the magnet 5A, and the retractable blade 20 moves in the direction of the rotation spindle MS due to the magnetic repulsive force of both. As a result of being pushed down, the wind receiving surface side of the retractable wing 20 comes into a state of approaching the outer peripheral surface of the rotating body 17. When the rotating body 17 further rotates and the magnet 11 of the retractable wing 20 approaches the magnet 22 of the fixed inner ring 10, the N poles of the magnets 11 and 11 and the S poles of the magnets 22 and 22 face each other. The retractable wings 20 fall on the outer surface of the rotating body 17 and are held in that state. Therefore, an obstacle that generates wind pressure torque does not protrude into the space 28.

  A part of the air discharged from the air collecting hood 3 to the air discharge port 4 enters the space 28 together with the rotating retractable blade 20, but the retractable blade 20 is in a fallen state in the space 28. The tip of the retractable blade 20 that has reached the vicinity of the outlet of the air collecting hood 3 is locked to the wind turbine stopping members 16 and 40 and immediately goes to the outlet of the air collecting hood 3. Due to the movement, the air pressure in the space 28 does not change significantly.

  When the retractable wing 20 further rotates and moves to the right side of FIG. 2 and the magnets 22 and 22 approach the first one of the magnets 12 and 12, the S poles of the magnets 22 and 22 and the S poles of the magnets 12 and 12 And the N poles of the magnets 22 and 22 are attracted to the S poles of the magnets 5B and 5B. As a result, the tips of the retractable blades 20 and 20 are raised toward the inner peripheral surface of the outer case 1. When the retractable wing 20 further moves, the movement is continued by the next magnet 12, and the movable blade 17 stands up with respect to the surface of the rotating body 17. If the rotation continues in this state, the tip end side of the retractable blade 20 reaches the wind turbine stopping members 16 and 40 and further rotation is prevented. In this state, the air blown from the wind collecting hood 3 is received over the entire surface, moves in the ventilation passage 29, and the above-described operation is repeated again. As a result, the retractable blade 20 can continue to rotate in a state where resistance as much as possible is eliminated. Then, the rotation main shaft MS rotates the rotation shaft (not shown) of the generator AN by the rotation of the tiltable blades 20 and 20, and the generator AN generates power.

  As described above, even when the wind around the wind power generator 10 is weak by repeating the standing and falling operations within the range of about 90 ° of the retractable blade 20 during the period in which the rotating body 17 rotates once. Since the wind pressure resistance from the back side of the wind receiving surface is not easily received, the retractable blades 20 and 20 rotate at a high speed.

[Effect of the first embodiment]
According to the wind turbine generator according to this embodiment, since the plurality of tiltable blades 20 and 20 are provided as the windmill mechanism 8, the wind turbine device 8 stands up in the ventilation path 29 extending from the wind collecting hood 3 to the air discharge port 4. On the other hand, since the entire surface faces each other, and in the space 28 where the wind pressure resistance is likely to occur, the retractable blades 20, 20 are configured to fall on the outer surface side of the rotating body 17. There is an effect that the power generation conversion efficiency can be improved significantly.

  In addition, the provision of the ring flywheels 15 and 18 on the upper and lower rotating plates 13 and 19 improves the rotational inertia of the rotating body 17, thereby increasing the rotational efficiency, thereby improving the power generation conversion efficiency.

  Furthermore, since the rotating shaft 21 of the retractable blades 20 and 20 is pivotally supported by the bearings 14 and 25, there is an effect that the rotating body 17 and the generator AN can be smoothly rotated while suppressing loss due to resistance. Therefore, efficient power generation becomes possible.

2. Second Embodiment Next, a second embodiment of the wind turbine generator according to the present invention will be described. FIG. 6 is a perspective view showing a second embodiment of the wind turbine generator according to the present invention (partially shown in a sectional view), FIG. 7 is a sectional view of the wind turbine generator shown in FIG. 6, and FIG. It is an exploded perspective view showing details. In this embodiment, in the first embodiment, all the magnets and the fixed inner ring cylinder 10 are removed, and the suction port 30 and the exhaust port are parallel to the ventilation path 29 from the air collecting hood 3 to the air discharge port 4. 39 is provided at a position deviating from the center of the cylindrical outer case 1 so as to communicate with the space 28, and a plurality of (here, five) air vent plates 31, 31 are provided on the outer surface of the rotating body 17. Other configurations are the same as those of the first embodiment.

  As shown in FIG. 8, the air vent plates 31 and 31 have a long plate shape, and in the longitudinal direction, the vicinity of the shaft portion of the tiltable blades 20 and 20 is locked to rotate the tiltable blades 20 and 20. Stop pieces 32, 32 for holding the body 17 in an upright state are provided at predetermined intervals, and a number of holes 33, 33 are provided at predetermined pitches in portions other than the stop pieces 32, 32. Yes. The holes 33 and 33 communicate with the inside of the rotating body 17, and the inside of the rotating body 17 communicates with the outside air. By providing a plurality of stop pieces 32, 32, the tiltable blade 20 can be stably supported. Further, since the internal air is released from the numerous holes 33, 33 provided in the wind vent plates 31, 31, the wind pressure on the retractable blade 20 is reduced.

  Next, operation | movement of the wind power generator 100 of 2nd embodiment is demonstrated. Similarly to the first embodiment, the retractable blade 20 in the passage 29 is rotated by the wind taken in from the air collecting hood 3 in the direction in which the tip approaches the inner peripheral surface side of the outer case 1, and the stop piece 32. Further, the rotation is restricted by the windmill stopping member 16, so that the rotating body 17 stands up. Therefore, the rotating body 17 rotates by efficiently receiving the wind from the wind collecting hood 3 on the entire surface of the retractable blade 20.

  On the other hand, the wind taken from the suction port 30 enters the upper side of the exterior case 1, passes through the space 28, and is discharged from the exhaust port 39 to the outside of the exterior case 1. When the retractable blade 20 passes through the vicinity of the air discharge port 4 and approaches the space 28, the retractable blade 20 is laid down along the surface of the rotating body 17 by the wind pressure of the wind passing through the space 28. In this way, it is possible to prevent wind pressure resistance from being generated in the space 28 by generating an air flow different from the air flow that rotates the retractable blade 20 in the space 28 in the outer case 1. Further, since the air vent plates 31 and 31 are provided with a large number of holes 33 and 33, when the retractable blade 20 falls, air escapes from the holes 33 and 33 to the inside of the rotating body 17 and further to the outside air. As a result, the pressure in the space 28 is prevented from increasing and the wind pressure resistance is reduced.

  According to the wind turbine generator according to the second embodiment, the same effect as that of the first embodiment can be obtained.

3. Third Embodiment [Configuration of Wind Power Generator]
Next, a third embodiment of the wind turbine generator according to the present invention will be described. FIG. 9 is a front view of a third embodiment of the wind turbine generator according to the present invention, and FIG. 10 is a plan view of the wind turbine generator of FIG. 9 with the upper rotating plate 60A removed. This wind power generator 50 is not a moving body, but is installed at a predetermined height position in an outdoor facility or the like, specifically applied to a street lamp. As a general rule, a plurality of (here, five) hoods Wind turbine mechanism 60 having attached retractable blades (hereinafter simply referred to as “fallable blades”) 61, 61, a generator AN provided at the center of the wind turbine mechanism 60, and a length that supports the wind turbine mechanism 60 and the generator AN. And a shawl pole 80.

  As shown in FIG. 10, the wind turbine mechanism 60 includes a plurality of (here, five) wind vent holes 65 and an upper rotating plate 62A and a lower rotating plate 62B in which a generator AN is mounted at the center. (See FIG. 9), stop rods 63, 63 provided near the outer periphery between the upper rotating plate 62A and the lower rotating plate 62B to restrict the rotation of the retractable blades 61, 61, the upper rotating plate 62A and the lower rotating plate The wind turbine support shafts 64 and 64 for fixing the rotating plate 62B are provided. In this wind power generator 50, the thing applicable to the exterior case 1 required by said 1st and 2nd embodiment is not provided. The reason is that the installation location of the wind power generation apparatus 50 is not a moving body but an outdoor facility, and the direction in which the wind arrives changes according to weather conditions or the like, so the opening is provided at 360 °. The wind power generator 50 is preferably installed in a well-ventilated place where the surroundings are open, avoiding places where trees are nearby.

  The retractable blade 61 has a shape in which a hood 66 having a semicircular bulging surface is provided at the tip of the retractable blades 20, 20 shown in the first and second embodiments, and is rotated by the rotating shaft 21. It is freely supported between the upper rotating plate 62A and the lower rotating plate 62B. The reason why the hood 66 is provided is to reliably capture the wind without missing it. The inside of the hood 66 has a concave shape so that the air can be accurately captured without missing the wind. The upper rotating plate 62A, the lower rotating plate 62B, the retractable blade 61, and the rotor of the generator AN are integrally rotated in the clockwise direction in FIG. The stator of the generator AN is fixed on the pole 80 side. A street lamp (not shown) is installed at an appropriate position of the pole 80 or the windmill mechanism 60. Further, although not shown, ring flywheels are provided on the peripheral portions of the upper rotating plate 62A and the lower rotating plate 62B as in the first and second embodiments.

[Operation of wind turbine generator]
Next, operation | movement of the wind power generator 50 of 3rd embodiment is demonstrated. In the following, the case where the wind is blowing from the left side will be described, but the same operation is performed regardless of the direction of the wind. When wind blows toward the windmill mechanism 60, wind hits the entire surface of the groove 27 of the retractable blades 61 and 61 and the hood 66 facing in the direction, and the upper rotating plate 62A and the lower rotating plate 62B are caused by the wind force. Are rotated in the clockwise direction shown in FIG. 10 to rotate the rotor of the generator AN. The retractable blades 61, 61 that have received the wind rotate and stand up around the rotation shaft 21, and stop at that position when their tip ends abut against the stop rods 63, 63. By receiving the wind in this state, the retractable blade 61 reaches the upper position shown in FIG. Further, when the retractable blade 61 and the upper rotating plate 62A and the lower rotating plate 62B are rotated, the retractable blade 61 is located on the back side of the generator AN with respect to the wind (located on the right side in FIG. 10). The air volume is reduced. Since the retractable blade 61 receives less wind and rotates, this time, it receives air resistance from the back side of the retractable blade 61, so that it comes into contact with the windmill support shaft 64 and falls on the rotating body 17. At the same time, air is released from the vent holes 65 provided in the rotary plates 62A and 62B, so that the resistance to the retractable blade 61 is reduced.

  By the operation of the retractable blade 61 as described above, the wind pressure resistance with respect to the retractable blade 61 in the region not directly receiving wind is remarkably reduced, and the upper rotating plate 62A is attached by attaching the rotating shaft 21 via a bearing. And the lower rotating plate 62B and the retractable blade 61 rotate smoothly. Then, when the retractable blade 61 reaches the left side shown in FIG. 10 after one rotation from the initial state, it again hits the entire surface of the hood 66 and the wind receiving surface of the retractable blade 61 and continues to rotate. Electric power is generated by rotating the rotor of the generator AN.

  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, each wave-curved windmill is configured to rotate on the horizontal plane (rotate in the horizontal position), but may be configured to rotate in the vertical position.

  Moreover, although the example which applies the wind power generator 50,100 which concerns on this invention to a street light was shown, it is also possible to apply to other facilities, for example, a common house, a lighthouse, a greenhouse, a warehouse, etc.
