Abstract

PROBLEM TO BE SOLVED: To easily confirm the position of a vessel and quickly and easily search the vessel when it is washed away by arranging, on the outer surface of the vessel, plural kinds of phosphorescent layers or fluorescent layers independently emitting light with mutually different colors as recognizing elements. SOLUTION: A cylindrical vessel 1 containing a water quality measuring circuit is formed by screwing a base screw 4b formed on the inner surface 4a upper end part of a protecting cover 4 to a screw 1b provided on the lower end part of its outer surface 1a to install the protecting cover 4 having a plurality of water passing slits 4c thereto. On the outer surface of the vessel 1, recognizing elements independently emitting lights with mutually different colors, which are, for example, formed of two kinds of phosphorescent layers or fluorescent 5a, 5b, are arranged. Since the position of the vessel 1 in water can be thus precisely recognized, the measurement by a measuring device can be precisely and easily performed. When an anchor cable is cut to wash away the vessel 1, it can be quickly and easily searched.

[0006]

The water quality measuring device as shown in FIG. 2 is used for measuring the water quality of rivers, lakes, marshes, sea areas, etc., and for information such as the depth position of the water quality measuring device in rivers, lakes, seas, etc. It is desired to perform measurement as a parameter used. For this reason, conventionally, information such as a depth position in a river, a lake, a marsh, a sea area, or the like of a water quality measurement device is obtained visually. However, in this case, as shown in FIG. 2, the water quality measurement device makes the outer surface 1 a of the container 1 to exhibit only a color with a low degree of recognition uniformly,
Therefore, when the container 1 has no recognizer on its outer surface 1a, it is difficult to accurately obtain information such as the depth position of a water quality measuring device in a river, a lake, a marsh, or a sea area.

Accordingly, in the case of the conventional water quality measuring device shown in FIG. 2, the water quality of rivers, lakes, marshes, seas, etc., is used as a parameter with information such as the accurate depth position in rivers, lakes, marshes, seas, etc. However, it has a disadvantage that it cannot be easily measured.

A water quality measuring device as shown in FIG.
It is normal to continuously measure the water quality of rivers, lakes, marshes, sea areas, etc. by anchoring them in the rivers, lakes, marshes, sea areas, etc.
Water quality measuring devices are so moored, rivers, lakes,
If it is washed away from a state where water quality is being measured, such as in sea areas,
It is necessary to search for the water quality measuring device. However, in such a case, as shown in FIG. 2 and as described above, the water quality measurement device makes the outer surface 1a of the container 1 to exhibit only a low-recognition color uniformly, and therefore, Container 1
However, if the outer surface 1a does not have any recognizer, it is difficult to search for the water quality measuring device.

Therefore, in the case of the conventional water quality measuring device shown in FIG. 2, it is tethered and, when the water quality of a river, a lake, a sea area, or the like is being measured, the water quality measuring device is searched when it is washed away. Cannot be performed quickly and easily.
