　従来から、流水式魚類試験に用いられる流水式魚類試験装置として、薬液と希釈水が混合された試験水で魚や貝などの水中内で生息している供試体を飼育させておく試験水槽と、試験水槽に試験水を供給する試験水供給手段と、試験水供給手段に希釈水を供給する希釈水供給手段と、試験水供給手段に薬液を供給する薬液供給手段とを備えるものが知られている（特許文献１）。この特許文献１の流水式魚類試験装置は、希釈水供給手段において計量した希釈水と、薬液供給手段において計量した薬液とを混合して試験水を作成し、この試験水を試験水槽に供給するものである。これにより、試験水槽内において飼育している供試体の生体を観察し、薬液の供試体に及ぼす生物学的又は化学的な安全性の評価を行うことができる。このように、流水式魚類試験装置は、薬液の供試体に及ぼす生物学的又は化学的な安全性の評価を行なうため、供給される試験水として使用される薬液及び希釈水を正確に計量する必要があり、この希釈水などの計量は、供給バルブを水位センサに連動させることによって行なっている。 Conventionally, as a flowing-water fish test apparatus used for flowing-water fish tests, test water tanks for raising specimens that live in water such as fish and shellfish in test water mixed with chemicals and dilution water, A test water supply unit that supplies test water to a test water tank, a dilution water supply unit that supplies dilution water to the test water supply unit, and a chemical solution supply unit that supplies a chemical solution to the test water supply unit are known. (Patent Document 1). This flowing water type fish test apparatus of Patent Document 1 prepares test water by mixing dilution water measured by the dilution water supply means and chemical liquid measured by the chemical solution supply means, and supplies the test water to the test water tank. Is. Thereby, the biological body of the specimen kept in the test water tank can be observed, and biological or chemical safety on the specimen can be evaluated. In this way, the flowing-water type fish test apparatus accurately measures the chemical solution and dilution water used as the supplied test water in order to evaluate the biological or chemical safety on the specimen of the chemical solution. It is necessary to measure the dilution water by interlocking the supply valve with the water level sensor.

　ところで、試験水は、薬液を希釈水によって希釈されたものであり、使用される希釈水は、薬液に比べて大量であるので、同時に同量の薬液と希釈水を供給する場合、希釈水の供給速度を速くする必要がある。しかしながら、従来の流水式魚類試験装置において、希釈水の供給速度を速くすると、水位センサに連動してバルブを閉じるまでの誤差による影響が大きくなり、希釈水の正確な計量を行なうことができないという問題がある。 By the way, the test water is obtained by diluting the chemical solution with the dilution water, and the dilution water to be used is larger than the chemical solution, so when supplying the same amount of the chemical solution and the dilution water at the same time, the dilution water is used. It is necessary to increase the supply speed. However, in the conventional flowing-water type fish test apparatus, if the supply speed of the dilution water is increased, the influence of the error until the valve is closed in conjunction with the water level sensor increases, and it is not possible to accurately measure the dilution water. There's a problem.

　次に、第１上流側希釈水用電磁弁３４の開口時から予め定められた時間が経過すると、第１上流側希釈水用電磁弁３４が閉口し（Ｓ２）、その後、希釈水計量容器２４内に所定量の希釈水が貯まったと希釈水センサ２９が検知すると、第２上流側希釈水用電磁弁４４が閉じる（Ｓ３）。また、これと並行して、薬液計量容器５４内に所定量の薬液が貯まったと薬液センサ５９が検知すると、上流側薬液用電磁弁６２が閉じる（Ｓ４）。 Next, when a predetermined time has elapsed since the opening of the first upstream dilution water electromagnetic valve 34, the first upstream dilution water electromagnetic valve 34 is closed (S2), and then the dilution water measuring container 24 is closed. When the dilution water sensor 29 detects that a predetermined amount of dilution water has accumulated therein, the second upstream-side dilution water electromagnetic valve 44 is closed (S3). In parallel with this, when the chemical liquid sensor 59 detects that a predetermined amount of chemical liquid has accumulated in the chemical liquid measurement container 54, the upstream chemical liquid electromagnetic valve 62 is closed (S4).
　第２上流側希釈水用電磁弁４４及び上流側薬液用電磁弁６２のうち閉口が遅い方の閉口時から所定時間経過後、下流側希釈水用電磁弁２８及び下流側薬液用電磁弁６６が開口し、希釈水計量容器２４内の希釈水と薬液計量容器５４内の薬液が貯水槽１２に供給される（Ｓ５）。希釈水計量容器２４内の希釈水と薬液計量容器５４内の薬液が貯水槽１２に全て供給されると、下流側希釈水用電磁弁２８及び下流側薬液用電磁弁６６が閉じる（Ｓ６）。 After a predetermined time has elapsed from the closing time of the later closing of the second upstream dilution water electromagnetic valve 44 and the upstream chemical solution electromagnetic valve 62, the downstream dilution water electromagnetic valve 28 and the downstream chemical solution electromagnetic valve 66 are The dilution water in the dilution water measurement container 24 and the chemical liquid in the chemical liquid measurement container 54 are supplied to the water storage tank 12 (S5).

　一方、試験中は、試験水供給用電磁弁１６を開けておく。すると、貯水槽１２に貯められた試験水は、試験水量調整弁１８によって適量に調整されて各試験水槽２に連続的に供給される。そして、常時、試験水が貯水槽１２に十分に貯まっているように、希釈水と薬液の供給を繰り返すことにより、試験水を連続的に試験水槽２に供給することができ、試験水槽２内の供試体２４の薬液に対する安全性の評価を行うことができる。 On the other hand, during the test, the test water supply solenoid valve 16 is opened. Then, the test water stored in the water storage tank 12 is adjusted to an appropriate amount by the test water amount adjusting valve 18 and continuously supplied to each test water tank 2. The test water can be continuously supplied to the test water tank 2 by repeating the supply of the dilution water and the chemical solution so that the test water is sufficiently stored in the water tank 12 at all times. It is possible to evaluate the safety of the specimen 24 with respect to the chemical solution.
　次に、本発明の第２実施形態に係る流水式魚類試験装置１´について、図５に基づいて説明する。第２実施形態に係る流水式魚類試験装置の試験水供給部１０は、第１実施形態と異なり、貯水槽１２を備えておらず、希釈水供給部２０´と薬液供給部５０´から直接試験水槽２´に希釈水及び薬液が供給されるように構成されている。この場合、第１実施形態と同様に、下流側薬液用連通管６４´の下流側は、下流側希釈水用連通管２７´の下流側と合流されて構成されているため、希釈水と薬液は、十分に混合された試験水の状態で試験水槽２´に供給される。第２実施形態に係る流水式魚類試験装置において、下流側薬液用連通管６４´と下流側希釈水用連通管２７´の合流された部分の管の長さを十分に長くすることにより、より混合された状態で試験水を供給することができる。 Next, a flowing-water fish testing apparatus 1 ′ according to the second embodiment of the present invention will be described with reference to FIG. Unlike the first embodiment, the test water supply unit 10 of the flowing water type fish test apparatus according to the second embodiment does not include the water tank 12, and is directly tested from the dilution water supply unit 20 'and the chemical solution supply unit 50'. It is comprised so that dilution water and a chemical | medical solution may be supplied to water tank 2 '. In this case, similarly to the first embodiment, the downstream side of the downstream chemical liquid communication pipe 64 ′ is merged with the downstream side of the downstream dilution water communication pipe 27 ′. Is supplied to the test water tank 2 'in the state of sufficiently mixed test water.

　第１及び第２実施形態に係る流水式魚類試験装置１、１´によれば、希釈水の計量を２段階、すなわち、第１上流側希釈水用電磁弁３４及び第２上流側希釈水用電磁弁４４を開口させて大量の希釈水を希釈水計量容器２４に供給する第１段階と、第１上流側希釈水用電磁弁３４を閉口させて第２上流側希釈水用電磁弁４４のみから調整的に希釈水を希釈水計量容器２４に供給する第２段階とに分けて行なうことにより、希釈水の計量の正確性を確保しつつ希釈水の計量及び供給速度を向上させることができ、これにより、大量の試験水の作成及び供給を可能とすることができる。 According to the flowing water type fish test apparatus 1, 1 ′ according to the first and second embodiments, the dilution water is measured in two stages, that is, the first upstream dilution water electromagnetic valve 34 and the second upstream dilution water use. The first stage in which the electromagnetic valve 44 is opened to supply a large amount of dilution water to the dilution water metering container 24, and the first upstream dilution water electromagnetic valve 34 is closed to only the second upstream dilution water electromagnetic valve 44. From the second stage, the dilution water is supplied to the dilution water measuring container 24 in a controlled manner, so that the measurement and supply speed of the dilution water can be improved while ensuring the accuracy of the dilution water measurement. Thereby, it is possible to make and supply a large amount of test water.
