DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a configuration of an anemoscope according to the present invention, FIG. 2 is a front view of the anemoscope, and FIG. 3 is a plan view of the anemoscope.

The anemometer 1 is installed mainly in the garden of a general household or the upper part of a building, and is used as a measuring device for informing the wind direction and the wind speed, and is also used as a decoration for outdoor use. The anemometer 1 generally has a head 2a and a tail 2b, and an intermediate part 2c connecting the head 2a and the tail 2b is supported rotatably in a horizontal direction. A column 3 rotatably supporting an intermediate portion 2c of the anemometer main body 2, a weather vane 4 projecting vertically from a tail portion 2b of the anemometer main body 2 to make the anemometer main body 2 parallel to the wind, and a wind vane A propeller 5 rotatably provided on the head 2 a of the main body 2, a generator 6 provided inside the anemometer main body 2 for generating power by rotation of the propeller 5, and an arbitrary number corresponding to the wind speed are stepwise. (In this example, 3
) Indicator lights 7 to 9.

The first to third indicator lights 7 to 9 are provided on each side of the anemometer main body 2 in three sets. In addition, since each of the indicator lights 7 to 9 has a light emitting surface formed in a hemispherical shape and protrudes on both sides of the anemometer main body 2, it is easy to see from the surroundings, and each indicator light is viewed from a direction other than the front and back. 7-9
Since the number of lightings of can be visually recognized, the wind speed level can be easily confirmed without going to the side of the anemometer 1.

The indicator lights 7 to 9 disposed on both sides of the anemoscope main body 2 are made of, for example, red light emitting diodes (LEDs) with low power consumption, and are generated by the generator 6 as described later. The lighting is performed stepwise according to the magnitude of the voltage value. The red light emitting diode (LED) is small and lightweight, but has a large light emission amount, so that it can be determined that the red light emitting diode is lit even from a distance.

The first to third indicator lights 7 to 9 are provided so as to be turned on or off stepwise by a control unit 20 installed inside the anemometer main body 2. In the case of the embodiment, when the wind speed is low (the propeller 5 rotates at a low speed), only the first indicator light 7 is turned on. When the wind speed is high (the propeller 5 rotates at a middle speed), the first indicator light 7 and the second indicator light 7 are turned on. Indicator light 8
Are turned on, and when the wind speed is high (the propeller 5 rotates at high speed), all of the first to third indicator lights 7 to 9 are provided to be turned on.

In this embodiment, the first to third indicator lights 7
Although the configuration is such that three levels of wind speed are displayed by turning on to 9 in stages, the number of display lamps may be increased to display four levels or five levels of wind speed. is there. Since the weather vane 4 protrudes vertically from the tail part 2b of the anemometer main body 2, when the wind direction changes, a horizontal rotational moment acts on the anemometer main body 2 by wind pressure from the lateral direction. Thereby, the anemoscope main body 2
The anemometer main body 2 rotates so that the head 2a of the wind turbine faces the windward direction, and the propeller 5 can receive the wind in front.

The propeller 5 includes a conical spinner 16 supported on a rotating shaft 15 and a spinner 16.
The blades 17a to 17c are provided at intervals of 120 ° extending from the outer periphery of the blade in a direction orthogonal to the direction in which the rotating shaft 15 extends. The blades 17a to 17c are inclined at a predetermined angle with respect to the axial direction so as to rotate the spinner 16 in response to an axial wind (air flow).

Therefore, the propeller 5 rotates at a rotation speed corresponding to the wind speed. The rotation of the propeller 5 is based on the rotation axis 1
5 and transmitted to a first speed increasing gear 18 of a gear mechanism provided at an end of the rotating shaft 15. Further, the rotation of the first speed increasing gear 18 is transmitted to a second speed increasing gear 19 of a gear mechanism provided on the shaft 6 a of the generator 6. Therefore, the generator 6 is driven to rotate at a speed higher than the rotation speed of the propeller 5 to generate power.

In the above embodiment, the rotation of the rotary shaft 15 is transmitted to the generator 6 via the gear mechanism.
However, the present invention is not limited to this. For example, instead of the gear mechanism, the rotation shaft 1 is connected via a belt-type transmission mechanism in which a belt is wound around a pulley.
Needless to say, the configuration may be such that the rotation of 5 is transmitted to the generator 6. Further, a toothed timing belt may be wound around the gear for slip prevention.

The rotating shaft 15 driven to rotate by the propeller 5 is directly connected to the generator 6 without passing through the speed increasing gears 18 and 19.
May be coupled so as to drive. Furthermore, the generator 6
Is not limited to one, and two may be provided. In this case, two generators 6 are arranged coaxially, and the rotating shaft 15 is penetrated through the first generator 6 and the end of the rotating shaft 15 is inserted into the second generator 6. Alternatively, two generators 6 are arranged in parallel, the first generator 6 is driven by the rotating shaft 15, and the second generator 6 is transmitted via a transmission mechanism such as a gear or a belt. May be driven.

A horizontal plate 10 is provided at the upper end of the weather vane 4, and a panel-shaped photovoltaic member 11 for receiving sunlight and generating power is provided on the upper surface of the horizontal plate 10. The horizontal plate 10 may be provided at the upper end of the weather vane 4,
Or you may make it provide in the upper part of the anemometer main body 2. Further, the photovoltaic member 11 is also called a solar module or a solar cell.

The electricity generated by the photovoltaic member 11 charges the battery 14 and serves as a power source for rotating the propeller 5 when there is no wind. Further, a light bulb 12 for night illumination is provided on the bottom surface of the tail part 2b of the anemometer main body 2. The light bulb 12 functions as a night exterior by brightening the area below the anemometer main body 2. The light bulb 12
Is not limited to the bottom surface of the tail 2b as described above.
It may be provided on the bottom side of the anemometer main body 2.

The upper end of the column 3 is fixed to a recess 2d which is opened at the bottom of the intermediate portion 2c of the anemometer main body 2.
3 so as to be freely rotatable. That is, the support 3
Supports the anemometer main body 2 via a bearing 13 so as to be rotatable so as to be able to rotate in the horizontal direction in accordance with the wind direction. By adjusting the total length, the anemometer main body 2 can be moved to an arbitrary height position. To support.

At the upper end of the support 3, the anemometer main body 2 is prevented from falling out of the support 3 even when receiving the wind pressure of the rising airflow.
A retaining member (not hidden and visible in FIG. 1) such as a retaining ring or a nut is attached. Therefore, anemometer 1
Is installed at a high place where the wind is strong, it is possible to prevent the anemometer main body 2 from being pulled out from the column 3.

A battery 14 made of a rechargeable nickel-cadmium storage battery is attached to the upper part of the bearing 13. The battery 14 is used as a power source when there is no wind, and is charged with extra electricity generated by the normal generator 6 and the photovoltaic member 11. Also, battery 1
Since the weight 4 is relatively heavy, it is installed on the rotation center of the anemometer main body 2 so that the rotational motion of the anemometer main body 2 is not affected by the moment of inertia. The battery 14
May be attached to a place other than the upper part of the bearing 13.

The anemoscope main body 2 is made of synthetic resin and has a hollow interior. For this reason, the anemometer main body 2 is reduced in weight, and the assembling and installation work of the anemometer main body 2 can be easily performed. Further, when the instantaneous maximum wind speed is far beyond the measurable range as in a typhoon or the like, the propeller 5 rotates at an abnormally high speed. Therefore, the anemometer 1 is provided with a braking mechanism (not shown) that applies a braking force to the rotating shaft 15 when the rotation speed of the propeller 5 exceeds the allowable range. As the braking mechanism, a configuration that generates a braking force by using a centrifugal force corresponding to the rotation speed of the propeller 5 or a configuration that generates a braking force by using a wind pressure acting in the axial direction of the propeller 5 is used. Can be

FIG. 4 is a circuit diagram showing a circuit configuration of the control unit 20. The current generated by the generator 6 is a diode D
1 is rectified. The night lighting bulb 12 is turned on only during the time period set by the timer 21 and is turned off during the day. For example, when the anemometer 1 is installed in a home garden, the light bulb 19 is turned on at night and the area below the anemometer main body 2 becomes bright, which is preferable for crime prevention.

The voltage applied to the bulb 19 and the indicator lights 7 to 9 is set to a constant voltage by the Zener diode Dz, and an excessive voltage when the propeller 5 rotates excessively is applied to the bulb 19 and the indicator lights 7 to 9. Is prevented from being applied. When the voltage generated by the generator 6 becomes 0.7 V or more, the voltage from the diode D1 is applied to the first indicator light 7, and the first indicator light 7 is turned on. Also, the generator 6
When the voltage generated by the above becomes 1.4 V or more, the voltage from the diode D1 is applied to the first indicator light 7 and the voltage from the diode D2 is applied to the second indicator light 8.

When the voltage generated by the generator 6 becomes 2.1 V or more, the voltage from the diode D1 is applied to the first indicator light 7 and the voltage from the diode D2 is changed to the second indicator light. 8 and the voltage from the diodes D3 and D4 is further applied to the third indicator light 9.

In the above embodiment, the configuration using the diodes D1 to D4 for a voltage of 0.7 V has been described as an example. However, when other diodes are used, the voltage value is naturally 0.7 V. Voltage values other than. The Zener diode Dz keeps the voltage applied to the bulb 19 and the indicators 7 to 9 constant, but may not be provided. Further, a protection circuit may be provided in place of the Zener diode Dz to prevent the voltage from exceeding a certain level.

In this way, with a simple circuit configuration, the indicator lights 7 to 9 can be turned on stepwise according to the wind speed, and the wind speed at that time can be displayed in real time. FIG. 5 is a plan view showing a first modification of the indicator light. 23 is a cylindrical member,
It is formed in a cylindrical shape by a synthetic resin material, and is fixed in a state where both ends are fitted into holes 2 e and 2 f opened on both sides of the anemometer main body 2. That is, the tubular member 23 is attached in a direction crossing the extending direction of the anemometer main body 2 at 90 ° inside the anemometer main body 2. Needless to say, the cylindrical member 23 may be mounted such that the direction of the cylindrical member 23 crosses the extending direction of the anemometer main body 2 at an angle other than 90 °.

At the center of the cylindrical member 23, an insertion hole 23a is formed, into which the indicator light 7 made of a light-emitting diode, a miniature bulb or a miniature bulb or a fluorescent lamp made of transparent or colored glass is inserted. Transparent (in the case of a light emitting diode) or colored (in the case of a miniature bulb) caps 23b and 23c formed in a hemispherical shape are fitted and fixed to both ends of the cylindrical member 23.

The caps 23b and 23c protrude from both side surfaces of the anemometer main body 2 (or are formed so as to be flush with both side surfaces of the anemometer main body 2). The light exit surface is provided on both sides of the anemometer main body 2. In this embodiment, the cap 23
b, 23c are hemispherically recessed, but the cap 2
The inside of 3b and 23c may be a plane.

On the inner peripheral surface 23e of the hollow portion 23d of the cylindrical member 23, a reflective film 2 of high reflectivity such as silver or gold is provided.
5 are coated. In this embodiment, the reflective film 25 is plated on the entire inner peripheral surface 23e of the tubular member 23.
Since the inner peripheral surface 23e of the cylindrical member 23 is coated with the reflective film 25, the light emitted from the indicator lamp 7 is reflected by the reflective film 25 and the caps attached to both ends are formed. 23b and 23c. That is,
A part of the light emitted from the indicator lamp 7 is directed directly to the caps 23 b and 23 c provided at both ends of the tubular member 23, and the light directed to the inner peripheral surface 23 e of the tubular member 23 is reflected by the reflection film 25. The caps 23b provided at both ends by reflection at
23c.

As described above, the light emitted from the indicator lamp 7 is reflected directly or by the reflection film 25 and the caps 23 at both ends are formed.
b, 23c. Therefore, when one indicator light 7 emits light, light can be emitted simultaneously at two places on both side surfaces of the anemometer main body 2. Therefore, each indicator light 7
The number of indicator lamps can be reduced by half and the manufacturing cost can be reduced as compared with the case where 2 to 9 are provided on both sides of the anemometer main body 2.

FIG. 6 is a plan view showing a second modification of the indicator lamp. Reference numeral 24 denotes a cylindrical member, which is formed of a synthetic resin material in a cylindrical shape, similarly to the cylindrical member 23, and is fixed in a state where both ends are fitted into holes 2e and 2f opened on both sides of the anemometer main body 2. ing.

In the center of the tubular member 24, an insertion hole 24a is formed, into which the indicator light 7 made of a light-emitting diode or a miniature bulb or a miniature bulb or a fluorescent lamp made of transparent or colored glass is inserted. Transparent (in the case of a light emitting diode) or colored (in the case of a miniature bulb) caps 24b and 24c formed in a hemispherical shape are fitted and fixed to both ends of the cylindrical member 24.

Further, on the opposite side of the insertion hole 24a, there is formed an inclined recess 24d which is recessed in a triangular shape. The inclined recess 24d has inclined surfaces 24e and 24f inclined at a predetermined angle symmetrical with respect to the axis. The inclined surface 24
e and 24f are formed such that the apex is located on the same line as the center of the indicator light 7.

The caps 24b and 24c protrude from both side surfaces of the anemometer main body 2 (or are formed so as to be flush with the both side surfaces of the anemometer main body 2). The light exit surface is provided on both sides of the anemometer main body 2. Also, the inner peripheral surface 24g of the cylindrical member 24
The reflection films 25a and 25b and 25c having high reflectivity such as silver or gold are coated on the inclined surfaces 24e and 24f. In this embodiment, the reflection film 25 is formed of the cylindrical member 2.
4 is plated on the entire inner peripheral surface 24g and the inclined surfaces 24e and 24f.

Since the inner peripheral surface 24g and the inclined surfaces 24e and 24f of the cylindrical member 24 are covered with the reflection film 25 as described above, the indicator lamp 7 removes the caps 24b and 24c.
In addition to the light emitted to the inclined surfaces 24e and 24f, not only the light emitted to the
The light is reflected by the reflective films 25b and 25c coated on the electrodes e and 24f, and guided to the caps 23b and 23c attached to both ends. That is, a part of the light emitted from the indicator lamp 7 is transferred to the caps 24 provided at both ends of the tubular member 24.
b, 24c, and the light heading toward the inner peripheral surface 24g of the cylindrical member 24 is reflected by the reflection film 25a to reach the caps 23b, 23c provided at both ends, and the inclined surface 24c.
Lights going to e and 24f are reflected by the reflection films 25b and 25c and become light going to the caps 23b and 23c.

As described above, most of the light emitted from the indicator lamp 7 is emitted from the caps 23b and 23c at both ends directly or after being reflected by the reflection films 25a to 25c. Therefore, the light emitted from the indicator lamp 7 efficiently transmits the caps 2 at both ends.
The light is emitted from 3b and 23c. Therefore, irradiance of the light emitted from the caps 23b and 23c is sufficiently ensured irrespective of one indicator light 7.

FIG. 7 is an exploded perspective view showing a third modification of the indicator light, FIG. 8 is a side view of the third modification before assembling, and FIG.
FIG. 3 is a side view after assembly. 26 is the upper case half (first
), Three half-cylindrical members 26a to 26c are integrally formed in parallel directions. At the center in the longitudinal direction of each of the semi-cylindrical members 26a to 26c, similarly to the case of the above-described cylindrical member 23 (see FIG. 5), an inclined concave portion 26l that is concave in a triangular shape is formed. The inclined concave portion 26l has inclined surfaces 26j and 26k inclined at a predetermined angle symmetrical with respect to the axis. In addition, the inclined surfaces 26j, 26k
Are formed such that the vertex is located on the same line as the center of the indicator light 7. In addition, the reflective film 2
7a to 27c are plated.

Reference numeral 28 denotes a lower case half (second case half), in which three half-cylindrical members 28a to 28c are integrally formed in parallel directions. Reflection films 29a to 29c are plated on the inner peripheral surfaces of the half cylindrical members 28a to 28c.
Further, the center portion of the semi-cylindrical member 28a~28c the insertion holes 28a ₁ ~28c ₁ for the indicator 7-9 is inserted is provided. In addition, each contact surface 26d~26g of the upper case half 26, the small hole 26 d ₁ to 2 for positioning
6 g ₁ are provided at three locations, and small contact holes 26 d ₁ are formed in the respective contact surfaces 28 d to 28 g of the lower case half 28.
Protrusions 28d ₁ ~28g ₁ fitted to ～26G ₁ is provided by three places. And the semi-cylindrical members 26a-2
6c and the semi-cylindrical members 28a to 28c, the reinforcing ribs 26h to 26k, 28
h to 28k are provided.

The upper case half 26 and the lower case half 28
Is divided by a plane along the axial direction, and is bonded in a state where the contact surfaces 26d to 26g and the contact surfaces 28d to 28g abut against each other. At that time, the projection 28d ₁ ~28g
₁ is fitted into the small hole 26 d ₁ ～26G ₁ abutting surface 26d~
The relative position between 26g and the contact surfaces 28d to 28g is regulated and positioned. As described above, the upper case half 26 and the lower case half 28 are in contact with the contact surfaces 26d to 26g and the contact surface 2d.
When 8d to 28g are adhered in abutted state, the three cylindrical members are integrated by the half cylindrical members 26a to 26c and the half cylindrical members 28a to 28c as shown in FIG.

Thereafter, hemispherical transparent caps 30a to 30f are fitted and fixed to the openings at both ends of each cylindrical portion. Thus, the indicator light unit 31 in which the three tubular members are integrated is completed. Since this indicator light unit 31 is formed by combining a pair of upper case halves 26 and lower case halves 28, the number of parts is reduced as compared with a case where a tubular member is manufactured for each of the indicator lights 7 to 9. The assembly process can be simplified, and the manufacturing cost can be reduced. Also,
The upper case half 26 and the lower case half 28 are provided with reflective films 27a to 27c, 29a to 29c on the inner peripheral surface in a half-split state.
Can be stably coated on the entire inner peripheral surface with a plating layer having a constant thickness.

In the indicator lamp unit 31, the reflection films 27a to 27c are formed on the inner peripheral surfaces of the semi-cylindrical members 26a to 26c and the semi-cylindrical members 28a to 28c and the inner surfaces of the inclined surfaces 26j and 26k.
7c, 29a to 29c are covered, so that the indicator light 7
Not only the light emitted from the display 30 to the caps 30a to 30f, but also the inclined surfaces 26j and 26k facing from the tip of the indicator lamp 7.
Is reflected by the reflection film coated on the inner surfaces of the inclined surfaces 26j and 26k, and guided to the caps 30a to 30f attached to both ends.

As described above, most of the light emitted from the indicator lamp 7 is directly or reflected by the reflection films 27a to 27c and 29a to 29a.
The light is reflected by c and emitted from the caps 30a to 30f at both ends. Therefore, the light emitted from the indicator lamp 7 is efficiently emitted from the caps 30a to 30f at both ends. Therefore, despite the one indicator light 7, the caps 30a-3
The illuminance of the light emitted from 0f is sufficiently ensured.

Since the main wings 33 and 34 have a large surface area,
The photovoltaic power generation member 11 can be added, and the amount of power generated by the spectral power generation member 11 can be increased.
As a result, insufficient charging of the battery 14 can be eliminated, and the design is close to that of an airplane, and the evaluation as an exterior can be enhanced.

Further, since the anemoscope 32 is provided at a high place, the indicator lights 7 to 9 are attached below the main wings 33 and 34. Therefore, daytime sunlight is irradiated on the photovoltaic member 11 disposed on the upper surfaces of the main wings 33 and 34, and
The indicator lights 7 to 9 are located in the shade of the main wings 33 and 34.

Therefore, when the indicator lights 7 to 9 are turned on stepwise according to the rotation speed of the propeller 5, since the indicator lights 7 to 9 are not directly irradiated with sunlight, the lighting of the indicator lights 7 to 9 is confirmed. It's easy to do. FIG. 12 is a side view of the third embodiment.
