Description

[0001]
BACKGROUND OF THE INVENTION
The present invention water clarity pool relates transparency with measuring kit to that pool water used to measure turbidity.
[0002]
[Prior art]
The degree transparency in the Ministry of Health and Welfare and pool water quality standards of the Ministry of Education the white line at the bottom of the pool that is filled with water looks clear, turbidity is determined that criteria such 3 degrees or less, but the lowest of these reference values pool water On the other hand, it is not really a clean pool.
Most of the actual pools are operated with transparency and turbidity below standard values. For example, it is not uncommon to see a pool with a transparency of 25m ahead in the state before swimming, and a turbidity of 0.1 degrees or less below the reference value. However, the pool a variety of dirt to bring Doors open after the swimmers, for example, other sweat and tears, look what the hair, etc., transparency due to cosmetics to issue only soluble in pool water, will lower the turbidity. In the pool, the transparency is observed from time to time, and when the transparency is poor and dirty, the abnormality of the purification device and the management status of the pool water can be quickly determined. When turbidity is present, not only the transparency is low, but the amount of chlorinating agent used is increased.
Conventionally, to observe the transparency of this pool water, a transparency observation mirror with a mirror provided on the frame at an angle of approximately 45 degrees is submerged on the bottom floor of the pool, the underwater side wall surface, etc. There is one in which the horizontal transparency in the water is observed and measured from the water at the periphery of the pool without diving (see Japanese Utility Model Publication No. 6-8539).
[0003]
[Problems to be solved by the invention]
Conventionally, when the pool water is indicated by a numerical value in order to measure the pool water, the analysis value of the pool water is low except for analysis of the pool water by a specialized analysis organization. Analytical values may be the same even in pools that are clearly different in appearance.
In addition, since the latter transparency observing table is directly submerged in the pool water, when an observer measures the mirror submerged from the water on the periphery of the pool, the reflection of light from the pool surface, the wave of the pool water, the pool There was a problem that it was difficult to see the image of the target image on the mirror and it was difficult to measure because the water was dirty and the mirror was placed on the floor of the pool. In addition, since the mirror touches the pool water directly, dirt in the pool water adheres to the mirror and the mirror surface becomes dirty.
[0004]
The present invention solves such a problem. A mirror is provided at the bottom of the cylindrical body, and only the lower part of the cylindrical body is placed in the water, and the upper part is exposed on the water, so that the measurement object reflected in the mirror can be easily seen. The transparency and turbidity of the pool water can be easily judged by the transparency measuring column, transparency indicator and judgment table that make it easy for the observation measurer to observe and measure the transparency and turbidity of the pool water on the water at the periphery of the pool. An object is to provide a transparency measurement kit.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of a transparency measuring barrel of the present invention, FIG. 2 is a sectional view thereof, FIG. 3 is a sectional view taken along line XX of FIG. 2, FIG. 4 is a front view excluding a front plate, and FIG. FIG. 6 is a front view of a judgment table showing the relationship between transparency, turbidity, and the appearance of an image reflected in a mirror, and FIG. 7 is a schematic side view showing an aspect of viewing a transparency measuring indicator in a pool with a transparency measuring barrel. 8 and 8 are plan views of the same.
[ 0009 ]
The transparency measuring barrel will be described with reference to FIGS. This transparency measuring lens barrel A includes a front plate in which at least a portion to be inserted into the water surface is transparent, and a mirror 7 is provided on a rectangular bottomed cylindrical body 1 formed in a sealed state except for a top view opening. Reference numeral 1 denotes a synthetic resin equiangular bottomed cylindrical body, which is formed in a square and hermetically sealed state by a front plate 2 having at least a transparent portion 2a to be inserted into the water surface, a side plate 3, a back plate 4 and a bottom plate 5. A viewing opening 6 is provided. The portion 2a to be inserted into the water surface of the front plate 2 is a transparent portion 2a at least from the lower end to a position above the mirror in order to see through the front with a mirror in water. In the embodiment, the front plate 2 itself is used as a transparent plate so that the front can be seen through. The cylindrical body 1 holds the upper part in the hand and puts about half to 2/3 into the water. The rectangular bottomed cylindrical body 1 needs to be light enough to block light entering from the surroundings to a certain extent, except for the front surface, and to be able to see a mirror surface, which will be described later, from the top view opening 6. When the lens barrel is brought in from a management room or the like due to high humidity in the pool, the inside of the tube becomes clouded due to a temperature difference. Therefore, it is desirable to coat the transparent portion 2a or the transparent plate and the mirror 7 inside to prevent fogging. The anti-fogging agent can be sprayed into the cylinder during use.
In the embodiment, the rectangular bottomed cylindrical body 1 uses a transparent plate so that only the front plate 2 can be seen through the front, and the surrounding side plates 3, the back plate 4, and the bottom plate 5 are light entering from the surroundings. A brown-smoked acrylic plate of a color that blocks the light is used so that an image D to be measured reflected on a mirror surface, which will be described later, can be seen from the top view opening 6. Moreover, the cylindrical body 1 is comprised by the sealing state so that water may not enter inside when it is put in water. The cylinder is subjected to a water leak test to check the sealed state. In addition, it is preferable that the measurement lens barrel has a size that can be supported with one hand in terms of buoyancy and size within a range where the inside of the tube can be cleaned. If the measuring barrel is made of synthetic resin, it can be made lightweight and easy to hold.
In the embodiment, the brown smoke acrylic plate is used around the cylindrical body. However, the present invention is not limited to this, and a material of appropriate color and material capable of blocking light to some extent can be used.
[ 0010 ]
At the bottom of the inner surface of the rectangular bottomed cylindrical body 1, a mirror 7 that is inclined at a predetermined angle θ and projects an underwater measuring object upward is installed opposite to the front transparent plate. This mirror 7 is a quadrangle having a size that just fits inside the cylindrical body 1, and its angle θ is inclined at a predetermined angle so that a measurement object separated forward in water can be projected upward. As the mirror 7, an acrylic mirror that is difficult to break is used to prevent broken pieces from entering the pool. In the embodiment, the predetermined angle θ with respect to the bottom plate 5 of the mirror is provided at approximately 45 degrees at the bottom of the inner surface of the rectangular bottomed cylindrical body 1 in order to project the horizontal measurement target in water upward by approximately 90 degrees. . Further, the upper and lower ends of the mirror 7 set to approximately 45 degrees are brought into contact with the front plate and the rear plate of the cylindrical body, and are fixed by being bonded with an adhesive. The inclination angle θ of the mirror 7 is not limited to the measurement object in front of the horizontal direction in the pool, but the measurement line such as the course line on the bottom surface in front of the pool, the course number on the wall surface on the opposite side of the pool, and characters. It can also be provided at an inclination angle that can be seen from above. That is, the inclination angle of the mirror is not limited to about 45 degrees, and there may be an inclination angle larger than that. The mirror 7 is not limited to an acrylic mirror, and may be made of glass or the like.
[ 0011 ]
The front plate 2 of the above-mentioned rectangular bottomed cylindrical body 1 of the pool water transparency measuring barrel A is provided behind the front end portions of both side plates by a width h in order to prevent contamination. As shown in FIG. 2, the transparent plate 2 of the front plate is fixed at a position slightly behind the front end portions of the side plates on both sides by a width h, and the front surface is formed in a concave shape. In the embodiment, the front plate 2 and the back plate 4 are positioned and fixed inside the front ends of the side plates 3. Thus, when this square-bottomed cylindrical body 1 is placed on the pool side or the like when not in use, the surface is not particularly in contact with the transparent portion of the front plate or the surface on which the transparent plate is placed. It can be prevented from being scratched.
[ 0012 ]
Since the transparency measuring lens barrel A of the present invention has the above-described structure, when measuring, the depth of sinking the measuring lens barrel is determined by submerging the mirror into the mirror by manually pushing in the lens barrel that floats with respect to the water surface. Then submerge and hold the measurement object in front, and measure in that state. That is, without immersing the mirror itself in water, as shown in FIGS. 7 and 8, the observation measurer S holds the transparency measuring barrel A by hand on the water at the periphery of the pool (pool side), and the lower part is below the surface of the water. The mirror 7 in the cylinder is positioned below the surface of the water, the upper surface viewing opening 6 is positioned above the water and the viewing opening is viewed through the mirror 7 inclined at about 45 degrees, and the transparent portion 2a of the front plate or the transparent plate 2 Observe and measure a measurement object at an arbitrary position separated from the front in the pool through the lower part. The image D to be measured is copied to the mirror 7 and measured with the eye of the measurer S. The measurer S moves the pool side until the image D reflected on the mirror 7 of the transparency measuring barrel A can be recognized, and the appearance of the image D to be measured reflected on the mirror 7 is clear, blurred or invisible. Judge transparency. That is, the transparency of the pool water is determined by how many meters the object to be measured can be seen. The measurer moves to a position where a person who satisfies the measurement conditions described below can recognize the image reflected in the mirror, and the image and image of the image D shown in the determination table C described below and the image reflected in the mirror at the position that can be recognized The transparency and rough turbidity can be easily judged just by comparing with the above.
[ 0013 ]
FIG. 1 to FIG. 6 show a pool water transparency measuring kit. The transparency measuring kit includes a transparency measuring barrel A, a transparency measuring marker B, and a determination table C.
[ 0014 ]
In FIG. 5, the transparency measurement mark B will be described. The transparency measurement mark B is made of a rectangular synthetic resin, and a cross-shaped measurement mark 11 in which black squares are arranged in a cross shape is drawn as a measurement object in the center of the front surface of the wooden board 10. The plate body 10 is provided with a suspension hole 12 at an upper corner, and can be suspended by a string or the like. The shape of the plate is not limited to a quadrangle, and may be an appropriate shape such as a circle. Further, the measurement mark 11 is not limited to the black cross-shaped display, and is a measurement mark having a color and a shape that allows easy recognition of characters, symbols, or figures. As a means for attaching the measurement marker, the plate body is provided with a suspension hole and suspended by a string, but the attachment means is not limited to this.
Further, in the embodiment, the case where the black cross-shaped measurement mark 11 is drawn on the plate body as the transparency measurement mark B is shown, but the present invention is not limited to this, for example, the water surface of the short side wall of the pool P Draw appropriate characters, symbols, and figures directly under the sign. Also, if there is a symbol such as a course name already under the water surface of the pool wall, it can be used as a measurement indicator. The bottom and wall lines of the pool can also be used as a sign. In addition to the measurement mark, a draft line for positioning to match the draft of the pool water may be displayed on the transparency measurement mark B.
[ 0015 ]
In FIG. 6, the structure of the determination table C for determining transparency and turbidity will be described. Judgment table C shows the relationship between transparency (m) and turbidity (degrees) on the rectangular plate 10 made of a material that may be wetted with water, such as synthetic resin, and the appearance of the image D of the measurement mark reflected in the mirror. Displayed as a table. Transparency is a value representing the transparency of water. In this table, the transparency is represented by the distance (m) where the image D reflected in the mirror can be seen, and the greater the distance (m), the better the transparency. Turbidity is the degree of turbidity in water. In this table, the larger the value of turbidity (degree), the more clearly the image D appears in the mirror and the more turbidity becomes.
In the judgment table C, the transparency (m) is shown in the vertical direction at a distance of 5 m from a distance of 5 m to 25 m, and the turbidity (degree) is shown in a horizontal direction from less than 0.1 to 0.10, 0.25, 0.60. The appearance of the image D reflected on the mirror 7 at each transparency and each turbidity is represented by a figure or a photograph. (The image shown in the drawing is a schematic representation of a photograph of the image reflected in the mirror, and is different from the actual photograph display.)
[ 0016 ]
A measuring method using this transparency measuring kit will be described below.
1. When starting the measurement, first, to measure the transparency of the pool P under almost the same conditions, first measure the illuminance with an illuminometer, and ensure that the brightness of the pool room is at least 150 lux in the official recognition rules of the pool. Check if it is.
2. A transparency measurement mark B is prepared, and as shown in FIGS. 7 and 8, the transparency measurement mark B is submerged in the course water along the wall surface on the short side of the pool so as to be perpendicular to the water surface. That is, the depth at which the measurement mark B is sunk is lowered to a position where the mirror of the transparency measuring barrel A and the measurement mark 11 of the measurement mark face each other horizontally. For example, the measurement mark 11 is positioned about 20-30 cm below the water surface, and the lower part of the transparency measuring barrel A is submerged in water for about 20 cm and observed and measured with a mirror.
3. On the opposite pool side, the measurer S sinks the lower part of the transparency measuring barrel A into the water by about 20 cm, and observes and measures the measurement mark B through the top viewing opening 6 of the transparency measuring barrel A. .
4. The measurer moves the poolside until the image D reflected on the mirror 7 of the transparency measuring barrel A can be recognized as a black cross.
5. The distance from the transparency measurement marker B to the measurer S is defined as transparency (m). That is, the transparency is determined by how many meters the object to be measured can be seen.
[ 0017 ]
Measurement condition 1, pool approved rules illuminance, 150 lux or more.
2. Use a transparency measuring tube.
3. Observe the transparency measuring tube 20cm below the water surface.
4. The eyesight of the measurer shall be 0.7 or more.
5. Measurement avoids the course where the water surface is reflected by outside light.
Although the measurer can measure while swimming, it is preferable to perform the measurement when there is no swimmer in order to accurately measure the swimmer without causing discomfort.
[ 0018 ]
Under the above measurement conditions, as shown in FIG. 7 and FIG. 8, the transparency measurement sign B is suspended and held perpendicularly to the water surface by appropriate means along the short-side wall surface of the pool. For example, the person S holds the upper part of the transparency measuring barrel A in his / her hand from the measurement sign B on the opposite side of the pool side, puts the lower part into the water, and looks forward through the upper surface peeping opening 6 on the water surface. The measurement mark B held vertically is observed and measured so as to be reflected on the mirror 7, and until the point where the black cross image D of the measurement mark of the measurement mark B reflected on the mirror 7 of the transparency measuring barrel A can be confirmed Transparency (m) can be determined by the distance from the transparency measurement sign B to the measurer S at a point where the black cross can be confirmed by moving along the side, and a black cross measurement mark at that point. See Judgment Table C for how the image D looks It is possible to determine the roughly turbidity.
For example, when the measurer S approaches the measurement mark B up to 20 m and the image D reflected on the mirror 7 looks slightly blurred, it is determined that the transparency is 20 m and the turbidity is 0.10. Thus, in order to keep the pool water clean, it is desirable that the transparency is 20 to 25 m and the turbidity is less than 0.1, and the clarification and turbidity of the circulated pool water can be maintained by the purification filtration device. Clean and sterilize with chlorine.
Therefore, the water in the pool can be easily measured using the transparency measuring kit consisting of the transparency measuring column, the transparency measuring label, and the judgment table. Immediately after the drop, the abnormality of the pool water purification filter device and the management status of the pool water can be quickly determined, and the pool water can be kept clean at all times. By making use of this measurement so that the transparency and turbidity of the pool water does not increase, it becomes possible to maintain a comfortable pool water, the amount of chlorinating agent can be reduced, and swimmers such as eye pain Can also prevent discomfort.

【The invention's effect】
According to this invention, the observation measurer holds the transparency measuring barrel on the water at the periphery of the pool, puts the lower transparent portion under the water surface, and places the upper surface peeping opening above the water so that the peeping opening is looked into the pool. Conveniently, it is possible to easily observe and measure a transparency measuring mark at an arbitrary position separated in front of the inside. When observing, there is no obstruction caused by the reflection of light from the water surface, which is sometimes rippling, and the measurement sign reflected in the mirror can be clearly observed, which is easy to measure. Moreover, since the mirror does not touch the pool water directly, the mirror surface can be kept clean. Moreover, this measuring barrel is lightweight and easy to carry.
