JP6687929B2 - Permeability measuring jig and fluorometer using the same - Google Patents

Description

  TECHNICAL FIELD The present invention relates to a fluoroscopic jig that enables simple and repeated measurement of water such as the sea, lakes and rivers, or other liquids, and a fluorometer using the same.

    As shown in FIG. 9, a conventionally used fluorometer has a double line perpendicular to the upper surface on the bottom of a transparent long cylindrical container 12 with a lower mouth having a depth of about several tens of centimeters. It has a configuration in which the white marker plate 18 is submerged. When using it, drain it little by little while loosening the pinch cock 17 attached to the rubber tube 16 of the water outlet 15 provided near the bottom, and observe from above the water surface in the long cylindrical container 12 with a lower mouth. When the double line marked on the sign plate 18 became clearly visible, drainage was stopped, and the water depth at that time was used as the transparency. See, for example, Non-Patent Document 1. However, in this case, the boundary of “visible / invisible” of the sign printed on the sign plate 18 is very delicate, and it is sufficient for an expert who is familiar with the fluoroscope to do it once, but for the general public it is 1 It is difficult to confirm by measuring once, and it is necessary to confirm by repeating the operation.

However, in the conventional fluorometer, the water level was adjusted by drainage from the water outlet 15 at the lower part, and therefore, when the water level was too high, it was necessary to add water again and find an appropriate water level by fine adjustment. For this reason, it takes time and labor, and if the amount of supplementary water is insufficient, it may not be possible to measure if drained too much.
In addition, when the measurement is repeated by a large number of people such as environmental learning, the appearance of each person is different, so that there is the trouble of having to repeat water supply or drainage to the long cylindrical container 12 with a lower mouth each time. It was

    Further, in Non-Patent Document 1, since the measurement scale is marked on the outer surface of the long cylindrical container 12 with the lower opening, and the drainage and the measurement are performed by one person, the double line of the white marker plate 18 After confirmation, the eyes had to be moved to read the scale marked on the bottomed long cylindrical container 12 from a horizontal position with respect to each measurement every time. .

    In addition, in the conventional fluorometer, since it is necessary to perform drainage and measurement by one person, it is necessary to set the distance such that the pinch cock 17 can be operated in a state of being viewed from above the lower opening long cylindrical container 12. Therefore, the length of the fluorometer is limited to about 50 cm, and therefore, the measurement of the fluorometer of 50 cm or more cannot be performed.

    In addition, when removing the test water remaining in the long-mouthed long cylindrical container 12 after the confirmation of the transparency, the water is often drained from the test water pouring port 15, and the mark on the bottom of the long-mouthed long cylindrical container 12 is shown. It was often the case that the plate 18 was discharged together with the drainage and became uncollectible.

    As a means for solving the above-mentioned drawbacks of the fluorometer, a fluorometer has been proposed which attempts to improve the water supply and drainage to the long cylindrical container. See Patent Document 1. However, in the fluorometer, the measuring scales are marked at equal intervals downward starting from the upper small hole outside the oblong cylinder, and the measurement must be started after the water surface is aligned with the zero starting point. .. Therefore, it is necessary to wait for the excess liquid to be removed from the water level hole at each measurement, a tool for receiving the test water spilled from the water level hole, and a marker plate with a thread. Since it is hung, the volume of the thread that gets into the water changes each time the sign board is moved up and down, and the water surface height deviates from the 0 starting point of the measurement scale. Therefore, the scale on the water surface and the scale on the top surface of the sign board It is difficult to maintain the level of the sign plate because the difference between the sign and the value of the transparency must be taken as the value of the transparency, and because the transparency plate moves up and down while always touching the oblong cylinder, check the double line of the sign plate. After that, there was a drawback that the scale had to be read from a horizontal position by moving the eyes. For this reason, there remains a problem that it is difficult for beginners such as children and ordinary people for environmental learning to handle.

    Further, as in Patent Document 2, even in the fluoroscopy in which the limitation of the length of the long cylinder of the conventional fluoroscopy is improved, the fluoroscopy has a more complicated and heavy structure. As a result, new problems such as the inconvenience of mobility and portability of the fluorometer and the need for a tool for receiving water spilled from the drain installed at the top of the main body arises. It was Further, in the fluorometer, although the sign board and the scale gauge are connected through a connecting member, the sign gauge and the scale gauge are covered with guide rails. Since it is interlocked with, it is difficult to adjust the thickness of the connecting material and the signboard, and the adjustment of the position of the 0 starting point when the position changes. Furthermore, each time the signboard is moved up and down, the volume of the gauge submerged in water changes, and the original reference water level, which is the starting point of 0, cannot be maintained. Therefore, it is necessary to correct the measured value for that purpose. Became. Therefore, it is difficult for beginners such as children and ordinary people for environmental learning to handle it.

    Further, as in Patent Document 3, even in a fluorometer in which a constant pulley is attached to the upper end of an elongated cylindrical container having a scale or to the upper end of the scale, vertical movement by a string attached to the end of the marker plate is performed. Has left the difficulty of twisting the strings and maintaining the horizontal condition of the signboard. Further, even in the measurement of the transparency, the troublesomeness of finding the difference between the scale on the water surface and the scale on the upper surface of the signboard has not been improved. For these reasons, the measurement is extremely troublesome for children and general beginners, and it is not suitable as a device that can be easily used outdoors.

    In the conventional fluorometer described above, since the instrument is supposed to be measured by one person, the length of the long cylinder of the fluorometer is limited, and repeated measurement by a large number of people is required. In order to use it as an educational material for environmental learning, it is necessary to have a test water as supplementary water for the number of participants, and the test water is often discharged from above the long cylinder at the time of drainage, and the signboard on the bottom also At the same time, it was often impossible to discharge and recover

    Furthermore, although proposals for solutions have been made, the need for a new tool for receiving spilled water due to the provision of a reference water surface in an oblong cylinder, horizontal stability of the signboard, and its Twisting of the hanging string, adjustment of the water surface height at the start of measurement, adjustment of the 0 starting point of the measuring scale, and mobility and portability of the measuring instrument will create new issues.

    The present invention is intended to solve the problem of such a conventional configuration, and a jig in which a measuring scale and a marker plate are attached / detached / integrated is installed in a water sample in an elongated cylindrical container. The transparency can be easily measured only by moving up and down. In addition, this reduces the measurement time and labor, repeat measurements by multiple people, the need for supplemental water, tools for receiving spilled water samples, the limit of the length of the long cylinder of the fluorometer, the collection of the marking plate, Horizontal stability of the signboard and twist of the string that hangs it, adjustment of the water surface height at the start of measurement, adjustment of the zero point of the measuring scale, and transparency with measures such as mobility and portability of the measuring instrument. The purpose is to realize the total.

Means to solve the problem

In order to achieve the above object, the present invention mounts a marker plate having a marker on its upper surface at the lower end of the measuring scale so as to be perpendicular to the measuring scale, and to the measuring scale. In a transparency measuring jig in which a measurement scale is marked upward with the upper surface of 0 as a starting point , the indicator plate is detachably attached to the lower end of the measurement scale through a locking member having a magnet or a fixed spring. It was done.

    A second solving means is the one described in the above item [0015], in which at least a surface of the measuring scale having markings is colored differently at predetermined intervals.

A third solution is to insert the transparency measuring jig described in the above [0015] and [0016] into a cylindrical container having a bottom.

The invention's effect

    As described above, the perspective measuring jig of the present invention and the fluorometer using the same are immediately poured by pouring an arbitrary amount of test water into a container and inserting a measuring scale equipped with a marker plate into the container. Since the measurement status can be obtained, the measurement time and labor can be reduced. Further, it is possible to directly measure a still water surface in the field by using a transparency measuring jig.

    Next, regarding the adjustment of the water level at the start of measurement, the measurement scale with the upper surface of the signboard as the 0 point is used to start the measurement at any water level without determining the water level in the container. Made possible

    Even if there is a difference in the thickness of the white marker plate, its upper surface can be aligned with the 0 starting point of the measuring scale and can be easily confirmed, and the reference water surface by raising or lowering the string or gauge for the measuring scale. It is not necessary to correct the measurement value of the fluoroscopy due to the fluctuation of the above, and further, the measurement range of the fluoroscopy can be widened as compared with the conventional fluoroscopy by utilizing the long measuring scale.

    By integrating the indicator plate and the measuring scale in [0015] and [0016] and displaying the color of the measuring scale in different colors, the water level of the measuring scale can be accurately adjusted without moving the line of sight when measuring the transparency. It made it possible to measure easily.

    With a jig that integrates the indicator plate and the measuring scale, it is possible to repeatedly and easily perform appropriate depth measurement by simply operating the measuring scale upward or downward without supplying or draining each measurement. Became. This enables repeated measurements by beginners and many people.

    It was often the case with conventional measuring instruments that the signage plate was discharged together with the drainage water after confirmation of the transparency, and it became impossible to collect it. It was possible to prevent it from being discharged.

    Since the marker plate is integrated at right angles by the measuring scale and the locking member, and the transparency is measured in a state of being installed horizontally, the horizontal stability of the marker plate can be easily provided.

    By integrating the sign plate vertically with the measuring scale, it solves the problems such as twisting of the string hanging the sign plate found in conventional measuring instruments, and improves the horizontal stability of the sign plate when measuring the transparency. Made it possible to keep.

    In addition, this fluorometer is composed of a fluoroscopic measuring jig and a container for receiving test water, and it can be stored and carried separately, and it has excellent mobility and portability of the measuring instrument. is there. The marker plate of the transparency measuring jig and the measuring scale are detachable, which makes the device even more convenient to carry. This enhances the ease of use for beginners and general members of society and as a measuring instrument outdoors.
