Abstract

The subject of the invention relates to a linear-current biodetector device associated with a detector of strong turbidity for monitoring water pollution. It is characterised by the combination of a working cell 1 of oblong cross section with a cylindrical body and frustoconical end pieces. A double alarm system is fitted to the apparatus: a manometric contactor 12 allows the death of the troutlet and consequently the eventuality of pollution, to be detected. A photoelectric cell 16 indicates the exceeding of a set-point turbidity threshold of the water and allows the life and behaviour of the young fish to be monitored. It is intended to detect the death of a troutlet of size 7 to 12 cm, swimming in a continuous flow of sample water. The surrender of the animal to the flow is detected by a double, hydraulic and electronic, monitoring.

Description

L'objet de l'invention concerne un dispositif biodétecteur à courant linéaire associé à un détecteur de fortes turbidités pour le contrôle de la pollution des eaux. The object of the invention relates to a linear current biosensor device associated with a high turbidity detector for controlling water pollution.

I1 est destiné à détecter la mort d'une truitelle d'une
taille de 7 à 12 cm, nageant dans un flux continu d'échantillon d'eau.L'abandon de l'animal au flux est détecté par un double contrôle, hydraulique et électronique.I1 is intended to detect the death of a trout from a
size from 7 to 12 cm, swimming in a continuous flow of water sample. The abandonment of the animal to the flow is detected by a double control, hydraulic and electronic.

Jusqu ' à ce jour on utilisait un biodétecteur de forme hémisphérique dont l'évacuation était située au pôle, ce qui cré
ait un vortex contre lequel la truitelle devait lutter pour ne pas être entraînée. Or, l'expérience a mis en évidence que les truitelles à la recherche d'un équilibre stable, s'abritent sous le tuyau d'arrivée de l'échantillon d'eau, zone morte ne subissant qu'un très faible renouvellement d'eau.Up to now, we have used a hemispherical-shaped biosensor whose outlet was located at the pole, which creates
have a vortex against which the trout would have to fight so as not to be trained. However, experience has shown that the trout, in search of a stable equilibrium, shelter under the inlet pipe of the water sample, dead zone undergoing only a very low renewal of water.

En outre, l'ancien système faisait l'objet de nombreuses fausses alarmes. In addition, the old system was the subject of numerous false alarms.

Le dispositif suivant l'invention supprime ces inconvénients en utilisant un courant linéaire pour que l'animal ne soit pas déséquilibré continuellement et ne subisse pas de forces latérales importantes. The device according to the invention eliminates these drawbacks by using a linear current so that the animal is not continuously unbalanced and does not suffer from significant lateral forces.

Il se caractérise par la combinaison d'une capsule de travail de section oblongue avec corps cylindrique et -embouts tronc coniques. Un double système d'alarme équipe l'appareil:
un contacteur manométrique permet de détecter la mort
de la truitelle et par conséquent l'éventualité d ' une
pollution.It is characterized by the combination of an oblong section work capsule with cylindrical body and conical trunk tips. A double alarm system equips the device:
pressure switch to detect death
of trout and therefore the possibility of a
pollution.

une cellule photoélectrique indique le dépassement
d'un seuil consigne de turbidité de l'eau et permet le
contrôle de vie de comportement de 1 'alevin. a photocell indicates that it has exceeded
a set water turbidity threshold and allows the
behavioral control of the fry.

Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention, le dispositif est représenté en élévation et dans son ensemble.  In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the object of the invention, the device is shown in elevation and as a whole.

L'appareil est constitué par une capsule de travail 1, formée par un récipient transparent cylindrique avec extrémités coniques. L'eau est introduite dans l'appareil gravitairement ou par pompage 3 et circule dans la capsule de la droite vers la gauc rle .  The apparatus consists of a working capsule 1, formed by a transparent cylindrical container with conical ends. Water is introduced into the device by gravity or by pumping 3 and circulates in the capsule from the right to the left.

La capsule étanche est mise à l'atmosphère par la purge 2 qui assure dans sapartie supèrieure la présence d'un
coussin d'air, nécessaire à la temporisation de l'alarme. En effet, si la capsule était pleine à 100 %, la moindre obstruction de quelques fractions de seconde de l'évacuation déclencherait l'alarme.The airtight capsule is vented by purge 2 which ensures in the upper part the presence of a
air cushion, necessary for delaying the alarm. Indeed, if the capsule was 100% full, the slightest obstruction of a few fractions of a second of the evacuation would trigger the alarm.

La mise en service s' effectue en fermant le robinet 4, en ouvrant les robinets 5, 6, 7, et en fermant le robinet 8. Commissioning is carried out by closing the tap 4, by opening the taps 5, 6, 7, and by closing the tap 8.

L'eau pénêtre alors dans la capsule 1 par l'orifice droit 9 et on arrête l'arrivée de l'eau lorsque celle-ci atteint le plan médian. On ouvre la trappe supèrieure 10 et on place la truitelle. On referme ensuite avec joint d'étanchéité. The water then enters the capsule 1 through the right orifice 9 and the arrival of the water is stopped when the latter reaches the median plane. We open the upper hatch 10 and place the trout. Then close with seal.

On réarme le boitier de commande et on régule par le robinet 6 afin que le niveau dans la capsule coïncide approximativement avec la prise de purge 11. L'appareil est ensuite en marche normale. The control unit is rearmed and regulated by the tap 6 so that the level in the capsule approximately coincides with the purge tap 11. The device is then in normal operation.

L'alarme hydraulique est basée sur l'augmentation de la pression ambiante dans la capsule intèrieure, en cas de non fonctionnement de l'alarme électronique. Sa prise de pression 11 est située au fond de la capsule et est reliée au contacteur manométrique 12. L'inversion du flux peut être utile pour dégager de l'orifice de sortie 13 la truitelle ayant déclenché l'alarme, pour cela, il suffit dé fermer les robinets 5 et 7 et d'ouvrir les robinets 4 et 8. Le sens de passage de l'eau libère l'animal, récupérable par la trappe 10.  The hydraulic alarm is based on the increase of the ambient pressure in the interior capsule, in the event of non-operation of the electronic alarm. Its pressure tap 11 is located at the bottom of the capsule and is connected to the pressure switch 12. The reversal of the flow can be useful for clearing the truitelle that triggered the alarm from the outlet orifice 13. to close the taps 5 and 7 and to open the taps 4 and 8. The direction of passage of the water releases the animal, recoverable by the hatch 10.

L'alarme principale est basée sur le principe d'interruption d'un faisceau lumineux excitant une cellule photoélectrique 16, placée sur le tube de sortie 13 de la capsule 1. The main alarm is based on the principle of interruption of a light beam exciting a photoelectric cell 16, placed on the outlet tube 13 of the capsule 1.

Ce tube translucide a été noirci sur quelques centimètres, sauf au niveau de la partie traversée par le rayon lumineux. La sensibilité de la cellule est réglable. Au bout de quelques minutes d'écoulement d'un flux pollué, la truitelle affaiblie se laisse entraîner vers la sortie de la capsule de travail, l'obst- rue et déclenche l'alarme en coupant le rayon lumineux. Avec une eau très fortement chargée, la fonction de biodétection n'est plus assurée par le circuit électronique, qui reste excité en permanence en alarme "forte turbidité", mais par le contacteur manométrique qui est relié au même système de signalisation.Dans ces conditions, on déconnecte le circuit électronique pour ne garder que l'alarme en provenance du contacteur manométrique. This translucent tube has been blackened for a few centimeters, except at the level of the part crossed by the light ray. The sensitivity of the cell is adjustable. After a few minutes of flow of a polluted stream, the weakened trout lets itself be drawn towards the exit of the work capsule, obstructs it and triggers the alarm by cutting off the light beam. With very heavily charged water, the biosensing function is no longer ensured by the electronic circuit, which remains permanently excited in "high turbidity" alarm, but by the pressure switch which is connected to the same signaling system. , the electronic circuit is disconnected to keep only the alarm from the pressure switch.

La mise en alarme implique, dans tous les cas, un arrêt de la pompe 3, la fermeture de l'électrovanne 14 et l'interruption de la source lumineuse d'excitation de la cellule photoélectrique 16. Un orifice 17, de mise à l'égout ou de stockage dans un bac de rétention complète cet ensemble.  The alarming implies, in all cases, a stop of the pump 3, the closing of the solenoid valve 14 and the interruption of the excitation light source of the photoelectric cell 16. An orifice 17, for setting the sewer or storage in a retention tank completes this set.
