Description

The present invention collects sample water for measuring components and measures the components from water fields such as pools, public baths, hotel reservoirs, water tanks of buildings, rivers, oceans, etc. It relates to a measuring device.

Water used in pools, public baths, hotel water reservoirs, water tanks in buildings, etc. comes into contact with the body when it enters the water, or is consumed by the body for drinks. Must be strictly controlled so as not to be harmful. In addition, the quality of water flowing in rivers and seawater in the ocean needs to be measured periodically to maintain and manage the natural environment.

As an example, swimming pools are managed in accordance with the “Swimming Pool Sanitation Standards” (July 24, 2001) according to the Ministry of Health, Labor and Welfare. That is, it is necessary to satisfy the following water quality standards for water used for swimming pools.
In addition, for the water quality standards determined in this way, the number of measurements is determined as follows as the maintenance standard.
Further, the water collection point related to the measurement object is “in the rectangular pool, 20 cm below the water surface at three or more positions on the diagonal in the pool and near the inlet of the circulation filter” Is also strictly defined.

As for water related to the human body in this way, the standards for managing its components are strictly defined, and the relevant water is collected from each facility by traders and organizations that handle water related to the human body, Ingredients are being measured. In addition, standards necessary for environmental maintenance are similarly set for water flowing into rivers and environmental water of seawater. There are two methods for collecting and measuring sample water from a water field: a simple measurement method using a colorimetric method and a measurement method other than the colorimetric method. A water collection container 100 shown in FIG. 14 is used. That is, the water sampling container 100 is composed of a container main body 102 and a lid 103 around which a string 101 is wound around the trunk, and is used as follows if the above swimming pool is taken as an example. That is, the water sampling container 100 is a thing in which a pool manager such as a supervisor removes the lid 103 from the container main body 102 and throws the container main body 102 from the pool side toward the measurement area while holding the string 101. When the thrown container body 102 is pulled up, the water in the measurement area is pumped into the container body 102 as sample water. In this state, the amount of sample water collected in the container main body 102 is adjusted to an amount (for example, 10 cc) with respect to the chemical whose component is to be measured, and after the chemical is introduced, the mouth of the container main body 102 is closed with the lid 103. Then, after thoroughly shaking the water collection container 100 and sufficiently dissolving the medicine in the collected water, the color development and a color contrast table (color chart, see FIG. 8) prepared in advance for each medicine are compared. Then, the component measurement of the sample water related to the measurement area is performed.

Further, as a measurement method other than the colorimetric method, for example, in the case of measurement of residual chlorine, it is assumed that the measurement is performed using a dedicated measuring instrument such as an electrode meter.

  However, according to the simple measuring method, the lid 103 of the water sampling container 100 has to be opened and closed every time the sample water is collected and measured, and the work is complicated. In addition, adjustment of the amount of sample water (for example, 10 cc) collected in the container main body 102 with respect to the chemical is, for example, transferred to another container with a scale such as a beaker and reduced while spilling from the container. Although it was adjusted to an accurate amount and then returned to the main body container 102, this work is extremely complicated, so in practice it is spilled directly from the state collected in the container main body 102. Therefore, adjustment as an approximate division amount has been performed, and it has been desired to achieve both accurate measurement and improved workability.

Further, when the water collection container 100 is pumped from the measurement region, water in a region other than the measurement region is mixed into the sample water, and accurate component measurement of the sample water in the measurement region is difficult. This problem can be solved by closing the lid 103 when the measurer directly enters the measurement area and collects the sample water in the measurement area. Accurate measurements that meet the standards were not made.

In addition, the measurement methods other than the colorimetric method have a problem in measurement cost because the dedicated measurement instruments are relatively expensive, and in addition, a dedicated measurement instrument must be prepared for each measurement target. Therefore, in order to measure different sample waters, the measurement cost is increased, and the installation, management and the like are complicated.

That is, the coupling portion 29 is formed as an opening on one end side in the pipe member 25, and the coupling portion 29 is extrapolated from the end opening side to the nozzle 11 so as to be freely coupled to the water supply portion 2. As the long member having flexibility, a known tube member having flexibility such as a rubber tube or a silicon tube may be applied. The pipe member 25 does not necessarily have flexibility, and an example in which such a pipe member is applied will be described as another embodiment described later.

The floating member 27 includes a main body portion 31 filled with air and an annular portion 32 disposed in the main body portion 31. The annular portion 32 is formed of a rubber material such as natural rubber or synthetic rubber. The annular portion 32 extends in the outer peripheral direction and passes through the tube member 25 from the coupling portion 29 side or the weight member 30 side of the tube member 25. After that, it is restored and attached to a predetermined position of the body portion 26 of the tube member 25, so that it can be detachably attached to a predetermined position of the body portion of the tube member 25.

The weight member 30 is formed thick at the center of the body portion to give a necessary weight, and one end side with respect to the body portion is used as an attachment portion 33 for attachment to the water collection port 28 (water collection portion) of the pipe member 25. At the same time, a weight sampling port 34 for collecting sample water is provided on the other end side. Between the both ends of the weight member 30, a water supply path (not shown) communicating from the weight portion water sampling port 34 is disposed, and the sample water collected from the weight portion water sampling port 34 is supplied to the tube member 25. Water can be sent. The weight member 30 is used to sink the water sampling port 28 (water sampling unit) side downward with respect to the body 26 in a state where the tube member 25 to which the floating member 27 is attached is placed in the water in the measurement area. It is formed of a member made of metal or synthetic resin. The weight member 30 only needs to sink the water sampling port 28 (water sampling unit) side downward with respect to the body 26 of the tube member 25. For example, the water sampling port 28 (water sampling unit) of the pipe member 25 may be used. ) It may be configured as a weight attached to a nearby barrel. In this case, water is collected directly from the water collection port 28 (water collection unit).

The operation of the sample water sampling and measuring apparatus 1 according to the first embodiment configured as described above will be described together with each use process. FIG. 4 is an image diagram showing a final use state of the sample water collection and measurement apparatus 1 according to the first embodiment. The operator throws in the tube member 25 of the sample water collection and measurement device 1 from the weight member 30 side from the land, pulls it up to the sample water measurement region T, and collects the sample water in the measurement region T in the container 4. The sample is taken in the region S and the measurement is performed.

(Chemical placement process)
In the method of using the sample water collection and measurement device 1, first, a chemical for measuring the sample water is introduced from the chemical introduction unit 8 and disposed between the head unit 5 and the water supply unit 2. FIG. 5 shows an example in the first embodiment used as a solid medicine. That is, the operator moves the head part 5 of the slide member 6 back to the base end side in the longitudinal direction (in the direction of arrow B) with respect to the chemical input part 8 and supplies the solid chemical 35 from the chemical input part 7. Thus, the medicine 35 is disposed in the recess 13 formed in the inner wall surface 10 of the water supply unit 2 (see FIG. 5a). From this state, the head portion 5 of the slide member 6 is advanced to the water supply portion 2 side (in the direction of arrow F), and the medicine 35 disposed in the concave portion 13 is pressed by the convex portion 19 protruding from the distal end side of the head portion 5.

(Water supply preparation process)
Next, the water supply part 2 is made to communicate with the measurement area T of the sample water, and water supply from the water supply part 2 is made possible. That is, after throwing the tube member 25 into the measurement area from the weight member 30 side, the coupling portion 29 on the proximal end side in the longitudinal direction of the tube member 25 is moved to the vicinity of the water surface, and the air in the tube member 25 is extracted and coupled. It is assumed that the sample water in the region to be measured has been fed to the position 29. From this state, the coupling unit 29 is coupled to the nozzle 11 of the water supply unit 2 so that water can be supplied from the water supply unit 2 to the container 4 of the sample water. At this time, as shown in FIG. 6, if the distance d from the weight sampling port 34 of the weight member 30 of the floating member 27 is set with a length distance equal to the depth D from the water surface of the measurement region, Sample water can be collected efficiently and accurately from the measurement region.

(Sample water collection process)
Then, as shown in FIG. 7, the operator holds the container 4 and the slide member 6 with one hand (for example, the right hand), and visually observes the amount of sample water collected in the measurement region S from the outside of the container 4. However, the slide member 6 is retreated to the sampling amount line (for example, 10 cc) targeted by the head unit 5. At this time, the operator places the thumb in the notch portion 18 of the plunger portion 17 and pushes up the flange-like operation portion 16 with the tip of the thumb to move the slide member 6 backward. That is, the operator can easily collect sample water using only one hand, and the working efficiency can be improved.

(Measurement process)
Finally, in a state where an appropriate amount of sample water is collected in the collection region S of the container 4, the container 4 is shaken well to dissolve the chemical 35 in the sample water, and the sample water is colored. The color of this sample water is compared with the color contrast table (color chart, see FIG. 8) that displays the color of each component held by the other unused hand (for example, the left hand). Will be measured. In such a measurement, since the sample water can be measured using the medicine 35 that has been preliminarily dispensed without attaching or removing the slide member 6 one by one, workability is greatly improved.
