Description

  The present invention comprises a windmill having blades attached to a rotating shaft, a light emitter attached to the blades of the windmill, and a control device that controls the lighting and extinction of the light emitters, and by rotating the blades of the windmill The present invention relates to a windmill capable of displaying a light emission image using an afterimage effect by turning on and off the light emitter by the control device on a rotation locus of the light emitter generated.

Conventionally, wind turbines that receive wind from blades and rotate to obtain power have been widely used for power generation and the like.
On the other hand, for example, rotary advertising devices installed on the rooftops of buildings or sidewalks are widely used. These rotary advertising devices rotate a display panel displaying advertisements, service contents, company names, and the like with a motor or the like, and are easier to attract people than a fixed type that does not rotate the advertising panel.

However, the rotating advertising device requires equipment such as a motor to rotate, and the installation cost and running cost are high.
Therefore, as a combination of the two, a rotating advertisement device in which an advertisement is directly attached to the blades of the windmill using the rotation of a widely used windmill can be considered. However, there are some types of blades that are difficult to mount advertisements, such as propeller type wind turbines and Darius type wind turbines. Even if the blade can be attached with an advertisement, the rotation speed of the blade of the windmill changes depending on the shape of the blade and the wind speed around the windmill, so it is difficult to always rotate the advertisement at the same rotation speed.

  Therefore, in Patent Document 1, as a technique capable of displaying an advertisement or the like using the rotation of a windmill, an electric light emitter is installed on a windmill blade or a portion that is rotated by receiving wind to detect a rotation angle. An electric display device using a windmill that draws an arbitrary character or figure at an arbitrary rotation angle position by an apparatus and a flashing and flashing program apparatus is disclosed.

JP 2003-184728 A

However, in the electronic display device using the windmill disclosed in Patent Document 1, since the rotation axis of the windmill is a horizontal axis, the blade is supported at one point by the rotation shaft, and the blade used conventionally has been newly added. It is difficult to attach the light emitter in consideration of the gravity balance, and the installation cost increases if a new light emitter-integrated blade is manufactured.
In addition, the distance between the blades is large, the number of light emitters that can be attached in the rotation direction is limited, and when the surrounding wind is weak and the rotation speed is low, the entire light emission image to be displayed does not remain as an afterimage, The luminescence image cannot be obtained. Even when the wind is weak, in order to obtain a desired light emission image, the number of blades must be increased, which also increases the installation cost.
Furthermore, when a plurality of light emitters are attached to the same blade, the rotational speed of the light emitters varies depending on the distance from the center of the rotation axis to the light emitters. Therefore, the light emitter flashing program for displaying an arbitrary light emission image Becomes complicated.
Further, the display cannot be visually recognized except in the windward direction, and whether or not the display is visible depends on the wind direction.

  Therefore, in view of the problems of the prior art, the present invention can display a light emission image even when a light emitter is attached even if the surrounding wind is weak and the rotation speed of the windmill is slow, even if a light emitter is attached. An object of the present invention is to provide a windmill that can display a display from any direction regardless of the wind direction and can display a light emission image without complicating a control device for controlling the light emitter.

A luminescent image is displayed using an afterimage effect.

By making the wind turbine a vertical axis wind turbine, the blades are supported at both ends on the vertical rotating shaft at two locations, so that even if a light emitter is attached to the blade, there is no problem in terms of gravity balance.
In addition, by attaching to the wing a plurality of light emitter rows in which a plurality of light emitters are arranged in the vertical direction, the rotational speed of the light emitters forming the same light emitter row is not greatly different, and a light emission image is displayed. The program is not complicated. In addition, when the wing | blade which attaches a light emitter row | line is largely curved, since the speed | rate of the light emitter which forms the same light emitter row | line | column differs, it is preferable to attach a light emitter row | line | column to the part where curvature is as small as possible.
By providing a plurality of wings to which the light emitter rows are attached in the rotation direction, the distance between the light emitter rows is shortened, and a desired light emission image can be displayed even at a low rotational speed. In addition, the number of light emitter rows to be attached to one wing is not limited to one row. If a plurality of light emitter rows are attached to one wing, the distance between the light emitter rows is further shortened, and even at a slower rotation speed. A desired illuminant image can be displayed.

Further, by controlling the lighting start and extinction time of the light emitter according to the display start signal timing and the rotation speed by the rotation position detection means and the light emission control means for detecting the rotation position of the wind turbine blade, for example, the ambient wind speed is Even when the rotational speed of the wing changes during display of the luminescent image due to factors such as change, the luminescent image can be continuously displayed at the same position and size. Further, for example, by moving the display position in the rotation direction or the counter-rotation direction for each rotation, it is possible to visually recognize the display of the light emission image in the 360-degree full-field direction.
One rotational position detecting means or a plurality of rotational position detecting means may be provided.

  Further, the wind speed detecting means for detecting the wind speed around the windmill, and whether the wind speed detected by the wind speed detecting means is a wind speed at which the blades can be rotated at a rotation speed at which a luminescent image display can be performed by an afterimage effect. A luminescent image display determining means for determining whether or not the determination result is acceptable, and a command to display the luminescent image is issued to the control device, and if the determination result is not possible, the luminescent image display is displayed on the control device. It is characterized by providing command means for issuing no command.

The windmill capable of displaying a luminescent image of the present invention can display a luminescent image even if the rotational speed is so slow that a conventional apparatus cannot display the luminescent image, but there is no wind or the windmill hardly rotates. In the case of such a breeze, the luminescent image cannot be displayed.
Emission image display judging means is provided, and it is judged whether the wind speed detected by the wind speed detection means is a wind speed at which the blade can be rotated at a rotation speed capable of displaying a desired emission image by the afterimage effect. If the desired emission image can be displayed, it is displayed, and if the desired emission image cannot be displayed, the emission image is not displayed. No light emission image is displayed.

An AC generator driven by the rotation of the rotary shaft of the vertical axis wind turbine, a rectifier that converts AC power obtained by the AC generator into DC power, and DC power converted by the rectifier is stored. A power storage device is provided, and power stored in the power storage device is used as at least a part of power used for turning on and off the light emitter, and rotation driving means for rotating or accelerating the windmill is provided. The generated electric power is used as part of the driving electric power for the rotation driving means.

In addition, a solar cell attached to the surface of the wing of the vertical axis windmill, and a capacitor that stores DC power obtained by the solar cell, the power stored in the capacitor is turned on and off of the light emitter In addition to being used as at least a part of the electric power to be used, a rotation driving means for rotating or accelerating the windmill is provided, and the electric power stored in the capacitor is used as driving electric power for the rotation driving means.
By using the power generated by the solar cell for turning on and off the light emitter, the power supplied from the outside can be reduced.
Also, by providing the rotation drive means, the desired emission image can be obtained by rotating or accelerating the windmill by providing the rotation drive means even when there is no wind or light wind where the desired emission image cannot be obtained only by the wind force. Be able to. By making the electric power stored in the electric accumulator part of the driving electric power for the rotation driving means, the amount of electric power fed from the outside can be reduced.

  Generally, windy days often have bad weather such as rain, and sunny days often have weak winds. Therefore, it is preferable to install both a windmill generator and a solar cell.

Further, the vertical axis wind turbine is a Darius Savonius type wind turbine in which an inner wing is a Savonius wing and an outer wing is a Darrieus wing, and the plurality of luminous body rows are provided in a Savonius wing which is an inner wing. To do.
The Darius-Savonius type windmill is a windmill that realizes high-efficiency power generation by using the Savonius windmill as a starter and performing output operation with the Darius windmill. It becomes possible.
Further, since the Savonius blade has a large blade surface area, it is possible to attach a plurality of light emitter rows to one blade. Further, the Savonius wing is an inner wing and rotates in synchronization with the Darrieus wing, which is the outer wing. Therefore, when the wind turbine is rotating, the peripheral speed is faster than that of the Darius wing, which is the outer wing.
Therefore, by providing the light emitter row on the Savonius blade, the light emitter row can be rotated faster than the outer blade, and the interval between the light emitter rows can be shortened. An image can be displayed.

Further, the vertical axis wind turbine is a Darius Savonius type wind turbine in which an inner wing is a Savonius wing and an outer wing is a Darrieus wing, and the plurality of luminous body rows are provided in a Darius wing which is an outer wing. To do.
The Darius wing is an outer wing, so it draws a rotating miracle with a larger radius than the inner wing. Therefore, a larger light emission image can be displayed by providing a light emitter row on the Darrieus wing. However, in order to obtain a desired light emission image, it is necessary to rotate the blade at a higher speed than when the light emitter row is attached to the Savonius blade.

  Note that whether the Savonius wing or the Darrieus wing is provided with a light emitter row is selected in consideration of the normal wind force at the installation location of the windmill capable of displaying the luminescent image of the present invention and the size of the required luminescent image. can do.

  The wing rotation surface and the background surface are illuminated by receiving the irradiation light irradiated toward the light emitting image display unit due to the afterimage effect of the windmill and lighting up so that the wing rotation surface has a light intensity difference with respect to the background surface. The wing rotation surface is emphasized by the difference in light intensity and the appearance is improved. Furthermore, the light emission image is also emphasized and the display is emphasized.

  As described above, according to the present invention, even if a light emitter is attached, there is no problem in terms of gravity balance, and even when the surrounding wind is weak and the rotation speed of the windmill is slow, a light emission image can be displayed. Therefore, it is possible to provide a windmill that can display a display from any direction and can display a light emission image without complicating a control device for controlling the light emitter.

  FIG. 1 is a perspective view of a windmill capable of displaying a light emission image according to the first embodiment, and FIG. 2 is a schematic configuration diagram of the windmill capable of displaying the light emission image according to the first embodiment illustrated in FIG. . A configuration of a windmill capable of displaying a light emission image according to the present invention will be described with reference to FIGS. 1 and 2.

  A windmill capable of displaying a luminescent image according to the present invention is generally configured by a windmill unit 1, a support 5, and a generator machine room 6. A plurality of Savonius blades 11 and a plurality of Darrieus blades 12 are attached to a rotating shaft 13 that forms the windmill unit 1, and a transmission shaft 51 is incorporated in the column 5. The generator machine room 6 incorporates a generator 61, a disc rotor 62 as a brake device, and a disc pad 63.

The support column 5 stands vertically above the generator machine room 6, and the upper end of the transmission shaft 51 incorporated in the support column 5 is connected to the lower end of the rotary shaft 13. On the other hand, the lower end of the transmission shaft 51 is configured to rotate the generator 61. That is, as is apparent from FIG. 2, the generator 61 incorporated in the generator machine room 6 is a low-rotation generator that can generate power by rotating at the same speed as the rotation of the windmill unit 1.
As shown in FIG. 2, a disc rotor 62 is provided at the intermediate portion of the transmission shaft 51, and the outer periphery of the disc rotor 62 is sandwiched between disc pads 63 to be braked.

  Although not shown, solar cells are respectively attached to the surfaces of the Savonius wing 11, the Darrieus wing 12, and the column 5. In particular, since the solar cells attached to the Savonius blade 11 and the Darrieus blade 12 are rotated by the rotation of the windmill, power generation is possible regardless of the direction of the sun.

In addition, as a characteristic configuration of the present invention, a light emitter row 3 in which a plurality of light emitters 2 are arranged in rows in the vertical direction is attached to the blades forming the windmill portion 1. 1 and 2 show a diagram in which one row of light emitter rows 3 is attached to only one of the plurality of Savonius blades 11, but the light emitter row 3 is attached to a plurality of rows on one blade. Alternatively, it may be attached not to the Savonius wing 11 but to the Darrieus wing 12. Further, not only one Savonius wing 11 or Darius wing 12 but also a plurality of Savonius wings or Darius wings 12 may be attached.
The light emitter 2 is not particularly limited as long as it emits light using electric power. For example, the light emitter 2 emits light at a high temperature such as an incandescent bulb, or the like emits light by discharge such as a mercury lamp. And those using light emitting diodes. In particular, the light-emitting diode is preferably used as the light-emitting body 2 because it has low power consumption, high luminance, and long life.

FIG. 3 is a plan view of a windmill capable of displaying the light emission images of FIGS. 1 and 2, and FIG. 3A is a plan view of an example in which the light emitter 2 (light emitter row 3) is attached to the Darrieus wing 12. 3 (B) is a plan view of an example in which the light emitter 2 (light emitter row 3) is attached to the Savonius blade 11. FIG.
As shown in FIG. 3A, since the Darrieus wing 12 has a narrow portion serving as the blade rotation surface, one row of the light emitter rows 3 is attached to one wing. On the other hand, as shown in FIG. 3 (B), the Savonius blade 11 has a wide portion serving as the blade rotation surface, so that two rows of light emitter rows 3 are attached to one blade, and in this embodiment, two rows of light emitter rows. However, the present invention is not limited to this, and one or three or more rows of light emitter rows 3 may be attached to one wing.

Therefore, when the light emitter row 3 is provided on the Savonius blade 11, the light emitter row 3 can be rotated faster than the Darrieus blade 12 and the interval between the light emitter rows 3 can be shortened. A desired light emission image can be displayed even at wind speed.
Further, when the illuminant row 3 is provided on the Darrieus blade 12, a larger luminescent image can be displayed. However, in order to obtain a desired light emission image, it is necessary to rotate the blade at a higher speed than when the light emitter row 3 is attached to the Savonius blade 11.
Both of them have advantages and disadvantages, and it is selected in consideration of the normal wind force at the installation location of the windmill of the present invention and the size of the required emission image, which of the Savonius blade 11 and the Darrieus blade 12 is provided.

FIG. 4 is an explanatory diagram of the principle of displaying a luminescent image using the afterimage effect. A case where 18 light emitters form one light emitter row and the letter “A” is displayed will be described with reference to FIG. 4.
When the light emitter row 3 reaches the light emission image display start position (light emission control start position), the second and third light emitters from the bottom forming the light emitter row 3 emit light. When the light emitter row 3 moves and reaches the second light emission control position, the second to fifth light emitters from the bottom emit light. In this way, when the light emitter row 3 moves and causes the predetermined light emitter 2 to emit light at a predetermined position, the light emission position remains as an afterimage, so that “A” appears to the human eye. appear.

Further, the windmill unit 1 is provided with a rotational position detecting means 8 that includes a Hall element and a magnet and detects the rotational position of the blade.
FIG. 5 is a plan view of the rotational position detecting means 8. The configuration of the rotational position detecting means 8 will be described with reference to FIG.
Six magnets 82 are arranged at intervals of 60 degrees on the rotary shaft 13 which is the same body as the wings (Savonius wing 11 and Darrieus wing 12). A hall element 81 is arranged on the fixed side, and the magnet 82 detects the magnetism by the hall element 81. When wind blows and the windmill rotates, the output signal of the Hall element 81 changes to detect the rotational position and speed of the blade (rotating shaft). The light emission is controlled by this detection signal.
In the present embodiment shown in FIG. 5, the luminous body 2 is installed on three wings, and three screens are displayed every 120 degrees. Further, by displaying the same content on the three surfaces, it is possible to recognize the display from any direction of 360 degrees.

  Next, an example of a light emission image display control signal using the rotational position detecting means 8 will be described with reference to FIG. FIG. 7A shows a Hall sensor signal detected by the Hall element 81 when the blade rotates. FIG. 7B shows an output waveform after AD conversion of the Hall sensor signal, and a pulse signal is generated every time the rotation shaft rotates 60 degrees. The rotational speed of the blade can be calculated from the time tr from the rising edge a of the pulse to the rising edge c of the next pulse. FIG. 7C shows a display start trigger signal output by the control display means 32 described later, which is output with a delay time from the falling edge d to td of the pulse signal of FIG. 7B. When this display start trigger signal is generated, an LED display signal shown in FIG. 7D is generated. In the LED display signal period tc, the LED display signal pulse width is changed according to the rotation speed calculated from tr. The light emission of the light emitter 2 is controlled through the switch means 33 described later by the LED display signal. By this control, the display can always be in a fixed position and size.

Next, an example in which the display of the light emission image is moved will be described with reference to FIG. The display position is moved as shown in FIG. 2 by extending the delay time td of the display start trigger signal shown in FIG. 7 for each rotation of the blade (rotating shaft). Thereby, one display can be displayed by moving 360 degrees, and the luminescent image can be viewed in all directions.
Further, the display of the three wing display bodies can be displayed differently, or one display image can be divided into three display bodies for display.

The AC power generated by the generator 61 is converted into DC power by the rectifier 14 and then stored in the capacitor 15.

On the other hand, the Savonius wing 11, the Darrieus wing 12, and the solar cell 16 attached to the surface of the column 5 generate DC power, and the generated DC power is stored in the capacitor 15.
The DC power stored in the battery 15 through the wind turbine 1 → the generator 61 → the rectifier 14 and the DC power stored in the battery 15 from the solar battery 16 are used as power for causing the light emitter 3 to emit light.

On the other hand, wind speed detecting means 31 for detecting the wind speed around the windmill is provided.
When the wind speed detecting means 31 detects a wind speed exceeding a predetermined wind speed A by a typhoon or the like, the disk pad 63 is actuated by the disk pad actuating means, and the disc roller 62 is sandwiched and braked to prevent the windmill from being damaged. , Stop the rotation of the windmill.
When the wind speed by the wind speed detecting means does not exceed a certain value A, the rotational position detecting means 8 detects the rotational position of the wing, and the display control means 32 controls the light emission of the light emitter 3 via the switch 33, and The light-up means 70 is controlled.
The display control means 32 needs to register a light emission pattern for displaying a desired light emission image in advance.

The process according to the detection result of the wind speed detection means 31 was shown using the flowchart in FIG. Based on FIG. 10, the process according to the detection result by the wind speed detection means 31 is demonstrated.

If YES, in step S2, the disk pad 63 is actuated as described above to sandwich the disk roller 62, and a brake is applied to stop the rotation of the windmill. On the other hand, if NO in step S1, the process proceeds to step S3.

In step S3, it is determined whether or not the detection result by the wind speed detection means is equal to or higher than the wind speed B at which the light emission image can be displayed. If it is YES, it will progress to step S4 and will light-emit the light-emitting body 3 based on the light emission pattern registered previously, and will display a light emission image. If “NO” in the step S3, the process proceeds to a step S5, and all the switch means 33 are controlled to be OFF so as not to display the light emission image.
Note that B is larger when the illuminant array is attached to the Savonius wing than when it is attached to the Darrieus wing.
