Abstract

PROBLEM TO BE SOLVED: To obtain a holding device by which an errorless and stable measured value can be acquired when ultraviolet rays by sunlight are measured by installing a fixation base or the like which shaft-supports a support base which holds an ultraviolet(UV) sensor so as to be freely rotatable. SOLUTION: A support base 1 which holds a UV sensor is shaft-supported by a fixation base 3 so as to be freely rotatable, and UV sensors are inserted into a recessed part 111 and a recessed part 111 on its upper plate 11. In the case of a manual operation, a rotating plate 41 is turned so as to be positioned in such a way that the support base 1 is directed to the direction of the sun, i.e., that the sun's rays are crossed at right angles to the longitudinal direction of the upper plate 11 at the support base 1. Then, a rod-shaped body 13 is monitored. When a shadow is recognized on the upper plate 11, a supporting and bearing plate 12 is turned until the shadow is not recognized. When the shadow disappears, the UV sensors are directed vertically to the sun. The sun is moved with the passage of time, and the shadow of the rod-shaped body 13 appears. Then, the supporting and bearing plate 12 is turned again so that the shadow disappears.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for holding an ultraviolet ray sensor (UV sensor) of an ultraviolet ray measuring device so as to be always perpendicular to the sun.

[0002]

2. Description of the Related Art Conventionally, when testing the efficacy of cosmetics,
The effect of ultraviolet rays on human skin is investigated. At this time, the amount of ultraviolet rays is measured using an ultraviolet ray measuring device. When measuring the amount of ultraviolet rays, relatively stable data can be obtained because there is no movement of the light source when using an artificial light source, but in the case of ultraviolet skin data due to sunlight, the angle of incidence of ultraviolet rays changes with the movement of the sun, so there is an error. Therefore, it was difficult to measure a stable amount of ultraviolet light without any problem, and it was difficult to obtain an accurate correlation between ultraviolet skin data and the amount of ultraviolet light.

In order to solve such a problem caused by sunlight and ultraviolet rays, the UV sensor of the ultraviolet ray measuring instrument is always oriented perpendicular to the sun, that is, the end face of the UV sensor is always perpendicular to the sunlight. As a matter of course, there is no suitable UV sensor holder for this purpose.

Therefore, in order to obtain a stable measurement value of the amount of solar ultraviolet light, a method of manually tilting the end surface of the UV sensor one by one according to the movement of the sun has been conventionally performed.
This method not only requires effort such as maintaining attention, but also
The disadvantage is that the timing of the movement is often lost, causing errors in the measured values.

[0005]

SUMMARY OF THE INVENTION The present inventors have conducted intensive studies on a method of obtaining a stable measurement value without error in measuring the amount of ultraviolet light by sunlight, and as a result, have made a UV sensor which is rotatable in the moving direction of the sun. It has been conceived that the rod should be set upright on the holder, and the rod should be rotated so that the rod is always vertical to the sun so that the holder does not shade the rod. The present invention has been completed.

[0006]

SUMMARY OF THE INVENTION The present invention provides a support for holding a UV sensor of an ultraviolet ray measuring device, a fixed base for rotatably supporting the support, and a base for fixing the fixed base. The support base is composed of an upper plate and a support plate for supporting both ends of the upper plate. The upper plate is provided with a concave portion for accommodating a UV sensor of an ultraviolet ray measuring device, and has a vertical rod. An ultraviolet ray measuring sensor holder, wherein a linear gauge is provided in the same direction as the longitudinal direction of the rod outside the support plate of the fixed base. is there.

Hereinafter, the contents of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the holder for an ultraviolet ray measurement sensor of the present invention. In the figure, reference numeral 1 denotes a support for holding a UV sensor 2 of an ultraviolet ray measuring device.
1 and support plates 12 and 12 for supporting both ends of the upper plate 11. The material of the upper plate 11 may be a rigid body having a strength enough to hold the UV sensor 2 of the ultraviolet ray measuring device, for example, paper such as cardboard, corrugated cardboard, wood, metal such as aluminum, iron, copper, or alloy. Any of ceramic, glass, celluloid and synthetic resin can be used. The upper plate 11 has the UV
It is a plate having a width, a length and a thickness such that at least two sensors 2 can be held in parallel with an interval therebetween.

On the upper surface of the upper plate 11, a concave portion 111 for accommodating the UV sensor 2 is provided, and
3 is fixed. The concave portion 111 is used for positioning the UV sensor 2 so as not to be displaced even when the support base 1 is rotated, and has a diameter matching the dimensions of the UV sensor 2. The UV sensor 2 is usually molded in a short cylindrical shape, but may be in another shape, for example, a prismatic shape. In any case, the concave portion 111 has a shape suitable for this. The depth of the concave portion 111 is U
The length may be arbitrarily determined from the entire length of the V sensor 2 to a depth which can be held to such a degree that the UV sensor 2 is not displaced even if the UV sensor 2 is rotated or inclined by about 20 degrees from the vertical position back and forth.

A rod 13 fixed on the upper surface of the upper plate 11
The upper plate 11 has a certain width when exposed to sunlight.
Any shape that can create shade, such as a nail, may be used, and the length is preferably about 2 to 10 cm.

The support plate 12 of the support 1 is provided with the upper plate 1
The material may be made of the same material or a different material as that of No. 1, but it is preferable to use a transparent material such as tempered glass, synthetic resin, or celluloid for the reasons described later. The support plate 12 is a plate-shaped member that is hung down from the longitudinal direction of the upper plate 11, that is, both ends in the serial direction of the UV sensors 2 and 2, and can be formed integrally with the upper plate 11. Accordingly, when the support base 1 is viewed from the front, the upper plate 11 and the support plates 12, 12 have a U-shape.

A linear meter 14 is provided outside the support plate 12 in the same direction as the longitudinal direction of the rod 13.
This gauge 14 fixes a wire or a needle, for example,
A straight line may be drawn or engraved on the outside of the support plate 12. The purpose of the gauge 14 is to measure the angle of the upper plate 11 and thus the angle of the sun by applying a protractor thereto. Therefore, the length of the gauge 14 may be any length that is sufficient for protractor measurement.

The support plate 12 is rotatably supported by the fixed base 3 so as to be rotatable. The fixed base 3 is preferably formed by connecting and fixing two semi-circular fixed plates 31 and 31 with a shaft 32 like a wheel.
It is fixed to. The shape of the fixing plates 31, 31 is not limited to a semicircle, but may be an arbitrary shape such as a semi-ellipse or a rectangle. Further, the shaft 32 is covered and protected by the shaft cover 33, but the form is not limited to the axle shape, and two short members may be used for each of the fixing plates 31, 31.

In the present invention, preferably, the fixing plate 3
A scale of 0 to 180 degrees is drawn or sculpted on the outside of 1, 31 for angle display so that it can be used as a protractor (see FIG. 1). In this case, the support plate 12 is made of a transparent material such as synthetic resin, glass, or celluloid, and the angle display scale can be read through the support plate 12. Further, in this case, the support plate 12 is pivotally supported so that the meter hand 14 indicates 90 degrees on the protractor scale when the support plate 12 is erected.

The base 4 for fixing the fixed base 3 may be a rigid body having a strength enough to support the fixed base 3.
For example, paper such as cardboard, corrugated cardboard, wood, metal or alloy such as aluminum, iron, copper, ceramics, glass,
Any of celluloid and synthetic resin can be used. The base 4 may be made in a plate shape having a certain thickness (see FIG. 2). Alternatively, a rotating plate 41 for fixing the fixed base 3 and a rotating plate 41 are made rotatable. And a housing plate 42 for housing
The rotating plate 41 can be rotated in accordance with the movement of the sun (see FIG. 1).

A magnet panel 43 and a level 44 may be attached to the base 4 to the accommodation board 42 to measure the direction and to secure the level of the base 4 (see FIG. 1).

In the basics of the present invention, the rotation of the support table 1 and the rotary plate 41 is performed manually, but they may be automatically rotated. That is, sensors 5, 5, 5,... For capturing shade are provided around a rod 13 standing upright on the upper plate 11 of the support table 1, and react to these sensors 5, 5, 5,. The support 1 and the rotary plate 41 may be rotated and stopped by driving the motor.

The holder for an ultraviolet ray measuring sensor according to the present invention has the above-mentioned configuration, and is used as follows.
First, the UV sensors 2 and 2 of the ultraviolet ray measuring device are inserted into the concave portions 111 and 111 of the upper plate 11 of the support base 1. U to use
The V sensor has at least two different wavelength ranges, UV
It is preferable to measure the A type (315 to 400 nm) and the UV-B type (280 to 315 nm) at the same time. For this purpose, both types of UV sensors 2 and 2 are inserted into each of the concave portions 111 and 111.

The next operation depends on whether the ultraviolet ray measuring sensor holder of the present invention is a manual apparatus or an automatic apparatus. When the UV measuring sensor holder of the present invention is manually operated, first, the support 4 is oriented so that the support 1 faces the sun, that is, the sun ray crosses at right angles to the longitudinal direction of the upper plate 11 of the support 1.
Alternatively, when the rotating plate 41 is provided on the base 4, the rotating plate 4
Rotate 1 for positioning.

Next, the rod 13 is monitored, and when shade is recognized on the upper plate 11, the support plate 12 is rotated until the shade is no longer recognized. When the shade disappears, the UV sensors 2, 2 are oriented perpendicular to the sun. That is, the end faces of the UV sensors 2 and 2 cross the sunlight at right angles. At this time, a protractor is applied to the measuring needle 14 or the fixing plate 31,
When 31 is made in the protractor, the angle of the sun is measured by reading the scale.

The UV skin data measurement test usually takes several hours. Therefore, the sun moves as time passes, and the shade of the rod 13 starts to appear on the upper plate 11. In this case, the support plate 12 is rotated again to eliminate the shade, and the angle of the sun is measured. By doing so, the UV sensor 2 is always oriented perpendicular to the sun, and no error occurs in the measured value of the amount of ultraviolet rays.

When the holder for the ultraviolet ray measuring sensor of the present invention is an automatic device, the sensors 5, 5, provided around the rod 13
When the shade is applied to 5 ..., the motor is driven, and the rotating plate 41 of the base 4 and the support base 1 are moved so that the support base 1 faces the sun.
Is rotated. When the sensors 5, 5, 5,... Are no longer shaded, the UV sensor 2 is oriented perpendicular to the sun and the motor is switched off. In this way, the rotating plate 41 and the support plate 12 automatically rotate with the movement of the sun, and the UV sensor 2 is always oriented perpendicular to the sun.

Alternatively, in the case of a manual apparatus, the UV measurement sensor holder of the present invention holds the UV sensor at the same angle as the object to be irradiated, and measures the amount of ultraviolet light actually irradiated on the object to be irradiated. Can also be used.

[0023]

The holder for an ultraviolet ray measuring sensor according to the present invention has a U
Since the V sensor is always perpendicular to the sun,
There is an advantage that a stable measurement value without error can be obtained in the measurement of the amount of ultraviolet light by sunlight.
