It is done by immersion in water. For this reason, approximately one week after the start of use, living things such as bacteria, barnacles, hydra insects, or algae floating in the water adhere to the surface of the underwater measurement sensor, causing the normal measurement function to be lost and measurement to become impossible. .

問題を生じている。<Problems to be Solved by the Invention> However, all conventional cleaning means require a large amount of electric power and cannot be applied to automatic measurement systems that operate with small electric power such as storage batteries or solar cells. In addition, the underwater measurement sensor is affected by noise during cleaning and cannot perform accurate measurements, so it is necessary to interrupt the 5+11 constant during cleaning, and some measurement items cannot be applied to the underwater measurement sensor.
It's causing problems.

A plurality of water holes 2 are provided on the side surface of a container 1 having a cylindrical shape with a bottom. The container 1 is made entirely of a black material or has a black coating material applied to its inner and outer surfaces so as to absorb scattered light in water.

計測センサ４による測定を可能ならしめるものである。The upper end surface of this container 'a1' is open, and the measuring device 3 is inserted in the axial direction from the open part. The measurement device 3 consists of a plurality of underwater measurement sensors 4 that measure various items such as a pH sensor, a DO sensor, and a salinity sensor, which are installed inside a cylinder 5, and the entire system is connected to external equipment ( (not shown). The container 1 is connected to a measuring device 3 via a mounting fitting 7 made of a wire, a hook, etc., and when in use, the measuring device 3 and container 1 are suspended underwater as a unit to perform measurements. Therefore, during measurement, the underwater measurement sensor 4 is enclosed in the container 1, which prevents light from entering the water and suppresses the growth of attached algae. Note that the water passage hole 2 is connected to the container 1.
This facilitates the flow of test water into the container 1 and enables measurement by the underwater measurement sensor 4 inserted into the container 1.

て調合される。From the viewpoint of processing, it is preferable that the nonionic surfactant maintains a solid or paste form at room temperature and changes to a liquid state when heated, and preferably has a suitable rate of dissolution in water. Furthermore, in consideration of environmental effects such as toxicity, it is preferable to use a material that decomposes within a short period of time after being dissolved. From this point of view, stearic acid alcohol-based nonionic surfactants and similar ones are selected as the nonionic surfactant. This substance is solid at room temperature,
In addition, it decomposes in water for 18 hours (27°C). The effective chlorine generating agent dissolves in water chlorine-containing substances that kill bacteria and repel attached organisms, and prevents these substances from adhering to the underwater measurement sensor 4. Hypochlorous acid or hypochlorous acid ions are good as effective chlorine-containing substances, and therefore hypochlorous acid or its salt should be selected as an effective chlorine generating agent. The hypochlorite ions generated from these substances have high acute toxicity, but they decompose quickly within a few hours, and are converted into chlorine ions through decomposition. Therefore, the conversion mixing ratio as hypochlorous acid is 10
%, it has little impact on the environment and can be used safely. The above protective agents have a dissolution rate of 5 to 10 g per day due to the period of use.
It is preferably about 0d, and is prepared using the above-mentioned substances or diluents.

期と夏期で試験した結果を示している。The thus formed maintenance device is used while being suspended in water by the cable 6. In this state of use, since the underwater measurement sensor 4 is enclosed in the container 1,
The growth of algae is suppressed by blocking underwater light, the surface of the underwater measurement sensor 4 is cleaned with a nonionic surfactant, and sterilization and repellent of attached organisms are performed with an effective chlorine-containing substance. Therefore, unlike physical cleaning, electric power is not required, so it can be applied to any automatic measurement system, and accurate measurement is possible without the influence of noise. In addition, the five maintenance agents are dissolved in the container 1 and maintained in a concentrated state in the container 1, so that the amount dissolved is small. Therefore, the cleaning, sterilizing and repellent effects can be maintained for a long period of time. FIG. 2 uses a Do sensor as an underwater measurement sensor and compares its error rate with the standard value of the reference Do sensor. Curve iA shows the results of testing in the summer with the protection device of the present invention attached, and curves B and C show the results of testing the Do sensor without the protection device in the winter and summer.

It is sufficient to maintain the potency, and such an amount is filled into the container 1 in relation to the amount dissolved. -Furthermore, underwater measurement sensors themselves are prone to drift (drift), etc., and maintenance and inspection are normally required once every two weeks to maintain normal measurement conditions. This is because the agent is replenished. Therefore, when continuous measurement is performed for two weeks or more, an amount of protective agent corresponding to that period is filled.
