Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention concerne un outil de nettoyage d'une piscine en milieu radioactif. L'outil de nettoyage est apte à être immergé au moins partiellement dans la piscine.The invention relates to a tool for cleaning a swimming pool in a radioactive medium. The cleaning tool is capable of being at least partially immersed in the pool.

ÉTAT DE LA TECHNIQUE ANTÉRIEUREPRIOR STATE OF THE ART

Des outils de nettoyage de structure connue pour piscine d'entreposage de matériaux radioactifs, en particulier d'assemblages de combustibles nucléaires, comprennent un châssis, un dispositif d'aspiration et un dispositif de filtration situé en aval du dispositif d'aspiration. Le dispositif d'aspiration et le dispositif de filtration sont montés sur le châssis. Ils servent à nettoyer l'eau de la piscine et/ou à récupérer des corps qui reposent au fond de la piscine.Cleaning tools of known structure for a storage pool for radioactive materials, in particular for nuclear fuel assemblies, comprise a frame, a suction device and a filtration device located downstream of the suction device. The suction device and the filtration device are mounted on the chassis. They are used to clean the water in the pool and / or to recover bodies that lie at the bottom of the pool.

De tels outils de nettoyage sont assez difficiles à déplacer et à installer dans la piscine. Les opérations de maintenance de ces outils de nettoyage sont souvent malaisées. Par ailleurs, ils sont susceptibles d'être contaminés par la radioactivité d'éléments, pièces ou corps, notamment issus d'opérations de manutention ou de maintenance qui ont pu chuter ou se déposer en fond de piscine.Such cleaning tools are quite difficult to move and install in the pool. The maintenance operations of these cleaning tools are often difficult. In addition, they are likely to be contaminated by the radioactivity of elements, parts or bodies, in particular resulting from handling or maintenance operations which may have dropped or been deposited at the bottom of the swimming pool.

WO 2013/030005 et WO 2015/040248 divulguent chacun un outil de nettoyage d'une piscine en milieu radioactif, de structure connue. D'autres outils de nettoyage des piscines sont divulgués par les documents EP1191166 et FR2742351 . WO 2013/030005 and WO 2015/040248 each discloses a tool for cleaning a swimming pool in a radioactive medium, of known structure. Other pool cleaning tools are disclosed in the documents EP1191166 and FR2742351 .

EXPOSÉ DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention vise à résoudre au moins partiellement les problèmes rencontrés dans les solutions de l'art antérieur.The invention aims to at least partially solve the problems encountered in the solutions of the prior art.

A cet égard, l'invention a pour objet un outil de nettoyage d'une piscine en milieu radioactif. L'outil de nettoyage comprend un dispositif de filtration de liquide et au moins une pompe.In this regard, the invention relates to a tool for cleaning a swimming pool in a radioactive medium. The cleaning tool includes a liquid filtration device and at least one pump.

Selon l'invention, l'outil comprend une cuve qui comporte une première ouverture, une deuxième ouverture, une entrée de liquide de la piscine et une sortie de liquide.According to the invention, the tool comprises a tank which has a first opening, a second opening, a liquid inlet from the swimming pool and a liquid outlet.

La première ouverture est destinée à y introduire au moins partiellement la pompe, et pour loger au moins partiellement la pompe dans la cuve. La deuxième ouverture, distincte de la première ouverture, est destinée à y introduire au moins partiellement le dispositif de filtration, et pour loger au moins partiellement le dispositif de filtration dans la cuve. L'entrée de liquide débouche dans la deuxième ouverture, le dispositif de filtration étant situé entre l'entrée et la pompe pour relier fluidiquement l'entrée de liquide à la pompe.The first opening is intended to at least partially introduce the pump therein, and to at least partially house the pump in the tank. The second opening, separate from the first opening, is intended to at least partially introduce the filtration device therein, and to at least partially house the filtration device in the tank. The liquid inlet opens into the second opening, the filtration device being located between the inlet and the pump to fluidly connect the liquid inlet to the pump.

L'outil comprend en outre un couvercle configuré pour fermer la première ouverture, et un conduit de refoulement qui est relié fluidiquement à la sortie de la pompe et à la sortie de liquide. Le conduit de refoulement traverse le couvercle. La pompe et le conduit de refoulement sont rigidement solidaires du couvercle.The tool further includes a cover configured to close the first opening, and a discharge conduit which is fluidly connected to the outlet of the pump and to the outlet of the liquid. The discharge conduit passes through the cover. The pump and the discharge pipe are rigidly secured to the cover.

L'outil de nettoyage est configuré pour aspirer du liquide de la piscine depuis l'entrée, puis à travers le dispositif de filtration, avant de lui faire traverser l'au moins une pompe.The cleaning tool is configured to draw liquid from the pool from the inlet, then through the filtration device, before passing it through at least one pump.

Grâce à l'invention, les risques de contaminer la pompe par des éléments radioactifs, particules, pièces ou corps, sont réduits, puisque le dispositif de filtration est destiné à retenir ces éléments avant qu'ils n'atteignent l'au moins une pompe. Le dispositif de filtration est situé immédiatement en aval de l'entrée de liquide, ce qui limite la contamination de la cuve et de la pompe.Thanks to the invention, the risks of contaminating the pump with radioactive elements, particles, parts or bodies, are reduced, since the filtration device is intended to retain these elements before they reach at least one pump. . The filtration device is located immediately downstream of the liquid inlet, which limits contamination of the tank and the pump.

Par ailleurs, le dispositif de filtration et l'au moins une pompe sont accessibles indépendamment l'un de l'autre, ce qui facilite des opérations de maintenance. De plus, le groupe de pompage, qui comprend la pompe, le couvercle de la première ouverture et le conduit de refoulement, peut être déplacé/retiré d'un seul tenant de la cuve, ce qui facilite notamment des opérations de maintenance.Furthermore, the filtration device and the at least one pump are accessible independently of one another, which facilitates maintenance operations. In addition, the pumping unit, which includes the pump, the cover of the first opening and the delivery conduit, can be moved / removed in one piece from the tank, which in particular facilitates maintenance operations.

L'invention peut comporter de manière facultative une ou plusieurs des caractéristiques suivantes combinées entre elles ou non.The invention may optionally include one or more of the following characteristics, whether or not combined.

Avantageusement, la pompe est fixée à la cuve, et le dispositif de filtration est fixé à la cuve.Advantageously, the pump is fixed to the tank, and the filtration device is fixed to the tank.

Le déplacement de l'outil de nettoyage et son installation dans la piscine sont alors facilités.The movement of the cleaning tool and its installation in the pool are then facilitated.

Selon une particularité de réalisation, la cuve comprend au moins un couvercle destiné à obturer la deuxième ouverture et un système de fermeture du couvercle.

Par ailleurs, les pinces 82 permettent d'ouvrir le couvercle 43 de chacun des groupes de pompage 40, 42, en le dévissant de la cuve 5, ou d'enlever le couvercle 61 de l'ouverture centrale 54 en faisant pivoter son système de fermeture 9.Furthermore, the clamps 82 make it possible to open the cover 43 of each of the pumping groups 40, 42, by unscrewing it from the tank 5, or to remove the cover 61 from the central opening 54 by rotating its system closing 9.

Les pinces 82 servent également à déplacer l'outil de nettoyage 2 en l'agrippant par la première anse 23, à déplacer les filtres 31 en les agrippant par leur poignée 33, et/ou à déplacer les groupes de pompage 40, 42 en les agrippant par leur oreille de levage 46 respectives.The clamps 82 also serve to move the cleaning tool 2 by gripping it by the first handle 23, to move the filters 31 by gripping them by their handle 33, and / or to move the pumping groups 40, 42 by gripping by their respective lifting lugs 46.

Enfin, les pinces 82 permettent d'ouvrir/de fermer chacune des vannes de refoulement 45, et d'ouvrir/de fermer la vanne de vidange 21.Finally, the clamps 82 make it possible to open / close each of the discharge valves 45, and to open / close the drain valve 21.

Le fonctionnement de l'appareil de nettoyage 1 est illustré plus particulièrement en référence à la figure 4.The operation of the cleaning appliance 1 is illustrated more particularly with reference to the figure 4 .

La cuve 5 est remplie avec de l'eau qui présente moins de contaminants pour les pompes 41 ou qui est sensiblement dépourvue de contaminants pour les pompes 41, avant d'être immergée dans la piscine 10.The tank 5 is filled with water which has less contaminants for the pumps 41 or which is substantially free of contaminants for the pumps 41, before being immersed in the swimming pool 10.

Les pompes 41 et le dispositif de filtration 3 sont en place dans la cuve 5, les ouvertures 52, 54, 56 sont obturés par les couvercles 43, 61, et la vanne de vidange 21 et les vannes de refoulement 45 sont fermées, lorsque l'outil de nettoyage 2 est déposé sur le fond 12 de la piscine 10.The pumps 41 and the filtration device 3 are in place in the tank 5, the openings 52, 54, 56 are closed by the covers 43, 61, and the drain valve 21 and the discharge valves 45 are closed, when the cleaning tool 2 is placed on the bottom 12 of the pool 10.

Par la suite, l'unité de commande 84 déclenche le fonctionnement de chacune des pompes 45 et les vannes de refoulement 45 sont ouvertes. Le liquide présent initialement dans la cuve 5 est évacué par les pompes 45 selon les flux F3, jusque dans la piscine 10 par chacune des sorties 7.Thereafter, the control unit 84 triggers the operation of each of the pumps 45 and the discharge valves 45 are open. The liquid initially present in the tank 5 is discharged by the pumps 45 according to the flows F 3 , as far as the pool 10 by each of the outlets 7.

Cette évacuation de liquide, typiquement de l'eau propre, provoque une aspiration de l'eau de la piscine à travers l'entrée 6 selon le flux F1. L'eau potentiellement contaminée de la piscine passe alors immédiatement dans les filtres 31 selon le flux F2. Les filtres 31 retiennent les éléments, pièces ou corps, radioactifs et autres contaminants en suspension dans l'eau de la piscine, ce qui limite la pollution de la cuve 5 et des pompes 41 et évite d'endommager les pompes 41.This evacuation of liquid, typically clean water, causes the pool water to be sucked through the inlet 6 according to the flow F 1 . Potentially water contaminated pool then immediately passes through the filters 31 according to the flow F 2 . The filters 31 retain the elements, parts or bodies, radioactive and other contaminants suspended in the pool water, which limits the pollution of the tank 5 and of the pumps 41 and prevents damage to the pumps 41.

L'eau de la piscine 10, préalablement filtrée et qui a rempli la cuve 5, est ensuite aspirée par chacune des pompes selon le flux F3 pour être acheminé vers les sorties 7.The water from the swimming pool 10, previously filtered and which has filled the tank 5, is then sucked up by each of the pumps according to the flow F 3 to be conveyed to the outlets 7.

En référence à la figure 5, l'entrée 6 est raccordée à au moins un tuyau d'entrée 62. Le tuyau d'entrée 62 est relié à son extrémité opposée à celle de l'entrée 6 à un écrémeur de surface 64 qui aspire l'eau, les particules et éléments flottants potentiellement radioactifs et autres contaminants à proximité de la surface de la piscine.With reference to the figure 5 , the inlet 6 is connected to at least one inlet pipe 62. The inlet pipe 62 is connected at its end opposite to that of the inlet 6 to a surface skimmer 64 which sucks up the water, the particles and potentially radioactive floating elements and other contaminants near the surface of the pool.

Cette eau et ces contaminants sont ensuite acheminés jusqu'à l'entrée 6 sous l'effet de l'aspiration des pompes 41, filtrés puis évacués, comme expliqué ci-dessus.This water and these contaminants are then conveyed to the inlet 6 under the effect of the suction of the pumps 41, filtered then evacuated, as explained above.

En référence à la figure 6, le tuyau d'entrée 62 est maintenu contre le fond 12 de la piscine par une perche 81 pour aspirer l'eau, les matériaux radioactifs et autres contaminants qui reposent au fond de la piscine.With reference to the figure 6 , the inlet pipe 62 is held against the bottom 12 of the pool by a pole 81 to suck up the water, radioactive materials and other contaminants which rest on the bottom of the pool.

Une fois les opérations de nettoyage de la piscine terminées, la cuve 5 est vidangée au-dessus de la piscine en ouvrant la vanne de vidange 21.Once the pool cleaning operations have been completed, the tank 5 is drained above the pool by opening the drain valve 21.

L'outil de nettoyage 2 permet ainsi de nettoyer efficacement la surface, le milieu et le fond de la piscine 10, tout en protégeant plus efficacement les pompes 41 et la cuve 5 de la contamination et de l'endommagement mécanique, par des éléments radioactifs, particules, pièces ou corps, et en facilitant les opérations d'installation, de mise en service et de maintenance de l'outil de nettoyage 2.The cleaning tool 2 thus makes it possible to effectively clean the surface, the medium and the bottom of the swimming pool 10, while more effectively protecting the pumps 41 and the tank 5 from contamination and mechanical damage, by radioactive elements. , particles, parts or bodies, and by facilitating the installation, commissioning and maintenance of the cleaning tool 2.

Bien entendu, diverses modifications peuvent être apportées par l'homme du métier à l'invention qui vient d'être décrite sans sortir du cadre de l'exposé de l'invention.Of course, various modifications can be made by those skilled in the art to the invention which has just been described without departing from the scope of the description of the invention.

En particulier, les ouvertures 52, 54,56 peuvent être disposées ailleurs que sur la partie supérieure de la cuve 5, par exemple sur le côté de la cuve 5. Elles peuvent ne pas être alignées.In particular, the openings 52, 54, 56 may be placed elsewhere than on the upper part of the tank 5, for example on the side of the tank 5. They may not be aligned.

L'outil de nettoyage 2 peut comprendre un seul groupe de pompage 40, ou plus de deux groupes de pompage 40, 42.The cleaning tool 2 can comprise a single pumping group 40, or more than two pumping groups 40, 42.

La cuve 5 peut être dépourvue d'anse 23 de levage.The tank 5 can be devoid of lifting handle 23.

L'outil de nettoyage 2 peut être dépourvu de conduit d'évacuation 71. Dans ce cas, les sorties 7 sont situées au niveau des vannes de refoulement 45.The cleaning tool 2 can have no discharge duct 71. In this case, the outlets 7 are located at the level of the discharge valves 45.

Par ailleurs, le nombre d'entrées 6 et de sorties 7 peut varier en fonction du débit de liquide circulant dans l'outil de nettoyage 2.Furthermore, the number of inlets 6 and outlets 7 can vary as a function of the flow rate of liquid circulating in the cleaning tool 2.
