Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind turbine generator that generates power using wind power and a power supply device using the wind turbine generator. About.

  Wind turbines can be broadly divided into horizontal axis types and vertical axis types. Vertical axis type wind turbines rotate regardless of the direction of the wind, so there is no need for a directional control mechanism, and a heavy generator is used. The advantage is that it can be placed near the ground.

  As a wind power generator provided with this vertical axis type wind turbine, there is a device disclosed in Patent Document 1 below. The wind turbine of this device is composed of a plurality of blades extending in the vertical direction, a plurality of arms extending radially to support the blades, and a rotating shaft that supports these arms. A lower portion of the rotating shaft is rotatably supported using a bearing, and a generator is provided at a lower end portion of the rotating shaft, that is, below the windmill.

  When the windmill rotates, power is generated by the generator, but if the windmill's rotational speed exceeds a certain speed, the windmill may be damaged. Is configured to be braked.

  A brake device (braking device) for this purpose has been constituted by a disc brake using a brake disc (brake disc) as disclosed in, for example, a brake for a vertical axis wind power generator disclosed in Patent Document 2 below. The disc brake is provided side by side with the generator on the rotating shaft constituting the generator.

  However, the disc brake has a configuration in which a brake pad is pressed against the brake disc to be braked by frictional resistance. Since the brake disc and the brake pad are configured to rub, wear occurs. For this reason, regular maintenance is required.

  Instead of such a mechanical brake, a brake device using an electromagnet and a conductor has been proposed as in Patent Document 3 below. The wind turbine generator having the brake device includes a support column and a cylindrical rotating body that rotates around the support column, and has an annular permanent magnet on an inner surface at an intermediate position in the longitudinal direction of the cylindrical rotating body, and a permanent magnet in the support column And a generator coil in a portion facing the generator constitutes a generator. The cylindrical rotating body has blades in the middle in the longitudinal direction of the outer peripheral surface. Then, the brake device includes a cylindrical rotating body due to an electric conductor provided on the inner surface of the lower end of the cylindrical rotating body, an electromagnet provided at a portion of the support facing the electric conductor, and an overcurrent generated by energizing the electromagnet. It is comprised by the control means which reduces the rotation speed of this.

  As described above, any of the brake devices of Patent Documents 2 and 3 is provided on a shaft (rotary shaft or column) separately from the generator.

  When the brake device and the generator are provided separately on the shaft, the length of the portion including them is required. For this reason, for example, it is difficult to adopt a configuration in which the small wind power generator is attached to a middle position in the longitudinal direction of the support column.

  Accordingly, the main object of the present invention is to make it possible to incorporate a device for braking in a compact manner and to reduce the thickness of the fixed portion with respect to the shaft.

  The power generating coil and the braking coil may be arranged on the same plane. The current applied to the braking coil may be power generated by the power generating coil and the permanent magnet.

  In this wind power generator, when the rotator is rotated by wind power, power is generated by the permanent magnet at the opposing portion of the rotator and the power generation coil at the overhanging portion of the stator. When the wind speed is high and the rotation speed of the rotator exceeds a set value, a current is applied to the stator braking coil by the control unit, and a braking force is applied to the rotator conductor to suppress the rotation.

  The wind power generator described above includes a support plate at one end in the longitudinal direction of the support column, and a secondary battery fixing portion for fixing the secondary battery to the surface of the support plate, and the secondary battery fixing portion. A receiving portion for fixing the solar cell panel to the surface side of the secondary battery, the electric power generated by the solar cell panel can be charged to the secondary battery, and the wind power generator is installed in the column. It can be set as the power supply device which was fixed to the other end side from the support plate, and was able to charge the secondary battery with the electric power generated with the wind power generator.

  If the column is provided with a lighting device that is lit with electric power charged in the secondary battery, a lighting device can be obtained.

  According to the present invention, there are provided a stator having a projecting portion that projects outward in the radial direction of the support column, and a rotator having a facing portion that faces the projecting portion in the longitudinal direction of the support column. Since the power generation member and the braking member are provided above, the braking device can be incorporated in a compact manner. For this reason, the thickness of the part fixed with respect to an axis | shaft can be comprised thinly, and it can use suitably as a small wind power generator.

  The solar controller 92 performs photovoltaic power generation power charging L4, light / dark detection, lighting on / off control L5 of the lighting fixture 16, and voltage monitoring of the secondary battery 14. Brightness / darkness is detected by the voltage of the solar battery panel 15. For this reason, when the voltage of the solar cell panel 15 rises during a bright day, charging is performed, and when the voltage of the solar cell panel 15 falls at night or the like, the battery is discharged and the lighting fixture 16 is turned on.

  The lighting device 17 composed of the above members first fixes the wind power generator 11 to the support column 12. The wind power generator 11 is inserted and fitted from the upper end of the support column 12, and the lock bolt 31 of the fixture 21c is rotated to perform fixing. The fixed position of the wind power generator 11 is appropriately set according to conditions such as the location of the lighting device 17. In this example, an example is shown in which the solar cell panel 15 is fixed at a position immediately below the upper end of the solar cell panel 15.

  Next, the solar cell panel 15 is fixed to the upper end of the column 12. For this purpose, as shown in FIG. 10, a predetermined number of lithium ion batteries 14a are connected to each other and stored in the storage case 14b, the lid 83 of the storage case 14b is closed, and then the storage case is stored. 14 b is fixed to the secondary battery fixing portion 64 of the support plate 61. Fixing may be performed using bolts 73 and nuts 74 as shown in FIG.

  Subsequently, the solar cell panel 15 is fixed to the receiving portion 65 of the support plate 61. Since the vertical length of the solar cell panel 15 is longer than the vertical length of the support plate 61, the support plate 61 can be fixed in either the vertical direction of the solar cell panel 15, but in contact with the control box 18, Fix in the middle position in the vertical direction.

  Thus, after integrating the solar cell panel 15 and the secondary battery 14 with the support plate 61, the support plate 61 is fixed to the upper end of the support | pillar 12. Fixing is performed by fitting the connecting pipe 62 on the back surface of the support plate 61 to the upper end of the column 12.

  The luminaire 16 is fixed at an appropriate position on the column 12. In the example of illustration, the example fixed to the position just under the wind power generator 11 is shown.

  In addition, necessary wiring (not shown) is not passed through the support column 12 but along the outside.

  In the lighting device 17 configured as described above, the wind power generator 11 generates power using wind, the solar cell panel 15 generates power using sunlight, and the power is generated by the wind power of the control unit 18a. The secondary battery 31 is appropriately charged based on the control of the controller 91 for solar power and the controller 92 for solar power. When it is detected that the solar battery panel 15 is in a dark state based on the voltage amount at the solar battery panel 15, the solar controller 92 discharges the power of the secondary battery 14 and supplies it to the lighting fixture 16, thereby lighting the lighting fixture 16.

  The solar cell panel 15 generates power only during the time when sunlight falls, and does not generate power during dark periods such as at night. On the other hand, since the wind power generator 11 provided integrally produces power by receiving wind, it can generate power regardless of day or night. Moreover, although the power generation capacity depends on conditions such as the form and number of the blades 14, continuous power generation can be achieved by providing the blades that can sufficiently rotate even with a light breeze.

  For this reason, it becomes possible to perform electric power generation as a whole as the illuminating device 11 whole. In other words, the wind power generator 11 supplements the power generation capability of the solar cell panel 15 in the lighting device 11.

  When a strong wind that damages the wind power generator 11 is blown during the power generation of the wind power generator 11, the wind power controller 91 performs stop control during strong wind.

  This strong wind stop control is a control that monitors the amount of wind power generation and suppresses or stops the rotation of the blades 44 when strong wind exceeds a preset wind power generation amount. Specifically, the wind power controller 91 detects the amount of power generated by the power generation coil 51 and the permanent magnet 53 with a voltage, and when the power generation amount exceeds a predetermined set value, the rotational speed of the blade 44 is increased. It is determined that the set value has been exceeded, and a current is applied to the braking coil 52 in the stator 21 of the wind turbine generator 11. In the braking coil 52, when an electric current flows, an attractive force is exerted on the conductor 54 of the opposing rotator 22, and the rotation of the blade is suppressed or stopped. Thereby, damage to the blades can be suppressed and durability can be enhanced.

  The wind power generator 11 has a stator 21 and a rotator 22 that are opposed to each other in the longitudinal direction of the support column 12 in a shape projecting radially outward of the support column 12 to be fixed. 51 and a permanent magnet 53 provided on the rotator 22 generate electric power, and a configuration for braking (braking coil 52 and permanent magnet 54) is also provided on the same plane.

  Since it is such a structure, the structure for a brake can be integrated compactly and the form of the rotation center part of the wind power generator 11, ie, the fixed part with respect to the support | pillar 12, can be made thin. For this reason, it is possible to obtain a compact and simple appearance and to easily adopt a structure in which the support 12 is fixed in the longitudinal direction as described above. This is an advantageous effect as a small wind power generator.

  In addition, regarding the arrangement of the power generation coil 51 and the braking coil 52, the braking coil 52 is provided on the outer peripheral side, so that the braking force can be exerted more strongly.

  Further, two overhanging portions 23 of the stator 21 are provided with a gap in the longitudinal direction of the support column 12, and the rotator 22 is held between these overhanging portions 23. Since the surface portion is provided with a configuration for power generation and braking (power generation coil 51, permanent magnet 53, braking coil 52, conductor 54), it is possible to obtain a sufficient amount of power generation, The braking force can also be fully exerted with a good balance.

  The effect of reducing the size of the wind power generator 11 can be enhanced by providing the blade 44 having a shape extending in the longitudinal direction of the support column 12 on the outer periphery of the rotator 22. This is because such a blade 44 is of a so-called vertical axis type and does not require a direction control mechanism. Moreover, since this kind of blade | wing 44 can be made into the form which rotates also with a breeze, it is effective at the point which supplements the electric power generation by the solar cell panel 15 as mentioned above.

  Since the wind power generator 11 is fixed by the fixture 21c that fixes the stator 22 at an arbitrary position on the support column 12, an optimal installation state can be obtained according to the wind condition at the installation location. In addition, fixing with the fixing tool 21c is simple and strong fixing is possible.

  The secondary battery 14 to be charged is held on the back surface of the solar cell panel 15 supported on the upper end of the support column 12, the control box 18 is also fixed to the back surface of the solar cell panel 15, and the whole is only on the upper end portion of the support column 12. Since it is a configuration that fits, it can be a very simple configuration and is easy to install. In particular, the wind power generator 11 can be fixed simply by being inserted into the support 12 and operating the lock bolt 31 of the fixture 21c. The solar battery panel 15 and the secondary battery 14 are assembled to the support plate 61 and the upper end of the support 12 is fixed. Installation is easy because it only needs to be fitted in.

  In addition, the rectangular plate-like lithium ion battery 14 a that is the secondary battery 14 is thin and lightweight, and the thickness from the back surface of the support plate 61 to the surface of the solar cell panel 15 can be kept thin. For this reason, it is a compact shape with a thin thickness and is lightweight. The fact that the storage case 14b for storing the lithium ion battery 14a is made of resin also contributes to weight reduction. As a result, even when exposed to wind and rain, it can be made highly durable.

  In addition, since the secondary battery 14 is stored in the storage case 14b and fixed to the secondary battery fixing portion 64 on the surface of the support plate 61, the storage case 14b also functions to reinforce the support plate 61. The strength of 61 can be increased. In addition, since the support plate 61 has a dish shape having a standing wall 66 at the peripheral edge, high strength can be obtained from this point. Since the reinforcing portion 70 is provided in a state where the upper standing wall 666c and the lower standing wall 66d are connected to an intermediate position in the left-right direction on the surface of the support plate 61, the strength of the support plate 61 is further increased. Since the connecting pipe 62 for supporting the support plate 61 is provided on the back side, the support state is also strong.

  On the other hand, since the notch 72 is formed in the support plate 61 to reduce the weight, an increase in weight can be suppressed. Further, since the notch 72 is circular, it is possible to avoid a situation where the strength is unduly impaired.

  Next, another example will be described. In this description, the same or similar parts as those in the above-described configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 14 shows a wind turbine generator 11, a power supply device 13, and a lighting device 17 according to another example. This wind power generator 11 has the same configuration as described above, but has a narrow support column 12a for fixing the stator 21. That is, the column 12a is not a hollow pipe having a thickness like the column 12 standing on the ground or road surface, but is formed of a thin solid rod.

  Specifically, the wind turbine mounting member 19 having the thin column 12a described above is provided at the upper end above the lighting fixture 16 of the column 12 having a thickness standing on the ground or road surface. The wind turbine mounting member 19 includes a column connecting portion 19a connected to the upper end of the column 12, a panel connecting portion 19b connected to the connecting tube 62 on the back surface of the solar battery panel 15, and the diameter of the column 12 in the vicinity of these opposing portions. It has the support frame 19c that protrudes and connects to the outside in the direction, and the above-mentioned thin support column 12a provided between the support connection portion 19a and the panel connection portion 19b.

  The strut connecting portion 19a is thick enough to be inserted into the strut 12, and is fixed to the strut 12 so as not to be relatively rotatable by appropriate means such as a bolt. In FIG. 14, reference numeral 19 d denotes a flange that contacts the upper end of the column 12.

  The panel connecting portion 19b has a thickness that can be inserted into the connecting tube 62, and is fixed to the connecting tube 62 so as not to rotate relative to the connecting tube 62 by appropriate means such as a bolt.

  The support frame 19c is U-shaped in a side view, and a plurality of support frames 19c, such as four or three, are provided radially from the center of the support column 12. The projecting length to the outside of the support frame 19c is set to a length that allows the wind power generator 11 to be accommodated therein. The support frame 19c is formed of a hollow pipe, and one end of the support frame 19c is fixed to the side surface of the upper end portion of the column connection portion 19a and the other end is fixed to the side surface of the lower end portion of the panel connection portion 19b by welding or the like.

  The thin column 12a is formed to have an appropriate thickness thinner than the column 12, and has a core 19e held at the lower end in the column connecting portion 19a so as not to be relatively rotatable, and at the upper end in the panel support portion 19b. It has a core 19f that is held in a relatively non-rotatable manner. The axis of the thin column 12a and the axis of the column 12 coincide.

  The wind power generator 11 configured in the same manner as described above is fixed to the thin column 12a provided in this way. Since the fixing to the support 12a is performed at a certain part on the support 12a, it can be performed by an appropriate means without using the fixing tool 21c as described above.

  Since the column 12a for fixing the wind power generator 11 is thin, the member used can be downsized. In particular, since a small bearing 27 can be used, the cost can be reduced. Moreover, since it can reduce in size, it is suitable for setting it as a small wind power generator.

In correspondence between the configuration of the present invention and the above-described configuration,
The fixing means of the present invention corresponds to the aforementioned fixing tool 21c,
The present invention is not limited to the above-described configuration, and other configurations can be adopted.

  For example, as a fixing means for fixing the wind power generator 11, for example, a hole may be made in the support column 12 and fixed with a bolt or the like.

  The support column may be fixed to the wall surface in parallel with the wall surface instead of standing on the ground or road surface.

  The power supply device and the lighting device can be configured only by a wind power generator.

  The power supply device can also be used for power supply to homes and the like.

  In addition to the back of the solar cell panel 15 as described above, the control unit 18a may be provided in other parts such as the support column 12, for example.
