DESCRIZIONE DELL’INVENZIONE INDUSTRIALE CHE HA PER TITOLO “GIUNTO PER CONNESSIONI ELETTRICHE SUBACQUEE" DESCRIPTION OF THE INDUSTRIAL INVENTION WHICH HAS THE TITLE "JOINT FOR UNDERWATER ELECTRICAL CONNECTIONS"
Al momento le soluzioni proposte in ambito subacqueo per la giunzione di connessioni elettriche sono sostanzialmente di due tipi: 1) connessione a secco realizzata a bordo di mezzi nautici e/o a terra dei connettori elettrici e successiva sigillatura della connessione a mezzo di guaina/resina protettiva. 2) utilizzo di connettori “bagnati” - ovvero collegabili e scollegabili direttamente in acqua - più semplici da utilizzare ma più delicati in quanto costituiti da membrane isolanti che garantiscono la tenuta per un numero finito di inserzioni ma che sono facilmente attaccabili da agenti marini nel caso di utilizzo per lunghi perìodi continuati. At the moment the solutions proposed in the underwater field for the junction of electrical connections are essentially of two types: 1) dry connection made on board nautical vessels and / or on the ground of the electrical connectors and subsequent sealing of the connection by means of protective sheath / resin . 2) use of "wet" connectors - that is, they can be connected and disconnected directly in the water - simpler to use but more delicate as they consist of insulating membranes that guarantee tightness for a finite number of insertions but which are easily attacked by marine agents in the event of use for long continuous periods.
Il trovato affronta e risolve la problematica relativa alla creazione di giunti a tenuta in grado di garantire isolamenti elettrici anche per tensioni superiori ad alcuni Kilovolt e che siano tuttavia di facile utilizzo e manutenzione garantendo allo stesso tempo un totale isolamento dei contatti elettrici rispetto all'acqua. Il trovato fa ricorso ad un liquido isolante di densità e quindi peso specifico superiore di circa 2 volte a quello dell'acqua. I contatti elettrici, immersi in esso, sono elettricamente isolati e fisicamente separati dall’acqua. In questo modo è possibile procedere con la giunzione dei cavi anche in immersione e tramite un semplice tappo di tenuta si garantirà la loro protezione. Infatti, il liquido all’interno del barilotto (Diesegno1.i) è sia incomprimibile sia insolubile, in questo modo si garantisce che l'acqua non sia in grado di entrare in contatto con le giunzioni, in quanto tende a portarsi sempre nella parte più alta del contenitore. Il barilotto è dimensionato in modo da accogliere le terminazioni giuntate dei cavi rappresentate da connettori. Il tappo del barilotto (Disegnol.h) è opportunamente forato per permettere il passaggio di cavi elettrici (Disegno 1.f). Il diametro del foro dove passa il cavo è anche sufficiente al passaggio del connettore relativo. Sul cavo, in fase di assemblaggio, si inserisce un anello troncoconico di gomma dura (Disegno 1.b) del diametro idoneo a garantire la tenuta una volta pressato e una farfalla filettata di serraggio (Disegno 1.a). La pressione sulla guarnizione di tenuta è assicurata dalla farfalla che è avvitata nell’alloggiamento realizzato sul coperchio (Disegno 1.g). È prevista una chiusura di sicurezza per impedire aperture accidentali sia per la farfalla che per il tappo (Disegnol .e), tramite fascette di serraggio. The invention addresses and solves the problem relating to the creation of sealed joints capable of guaranteeing electrical insulation even for voltages higher than a few Kilovolts and which are nevertheless easy to use and maintain while guaranteeing total insulation of the electrical contacts from water. . The invention makes use of an insulating liquid having a density and therefore a specific weight that is approximately 2 times higher than that of water. The electrical contacts, immersed in it, are electrically isolated and physically separated from the water. In this way it is possible to proceed with the junction of the cables even in immersion and by means of a simple sealing cap their protection will be guaranteed. In fact, the liquid inside the barrel (Diesegno1.i) is both incompressible and insoluble, in this way it is ensured that the water is not able to come into contact with the junctions, as it tends to always move to the most high of the container. The barrel is sized to accommodate spliced cable terminations represented by connectors. The barrel cap (Diagram h) is suitably perforated to allow the passage of electric cables (Diagram 1.f). The diameter of the hole where the cable passes is also sufficient for the passage of the relative connector. On the cable, during the assembly phase, a truncated cone ring of hard rubber is inserted (Drawing 1.b) with a suitable diameter to guarantee the seal once pressed and a threaded tightening butterfly (Drawing 1.a). The pressure on the sealing gasket is ensured by the butterfly which is screwed into the housing made on the lid (Drawing 1.g). A safety closure is provided to prevent accidental opening of both the butterfly and the cap (Diagram .e), by means of clamps.
Una volta serrate le farfalle, il barilotto riempito di liquido isolante sarà avvitato al tappo, un o-ring di tenuta (Disegnol .c) impedirà al liquido di trafilare verso l'esterno tramite la filettatura di serraggio (Disegno 1.d). Tutte le operazioni su descritte sono eseguite direttamente sott’acqua. Once the butterflies have been tightened, the barrel filled with insulating liquid will be screwed to the cap, a sealing o-ring (Drawing .c) will prevent the liquid from leaking outwards through the tightening thread (Drawing 1.d). All the operations described above are performed directly under water.
Gli eventuali residui di acqua presenti all'interno del barilotto una volta chiuso tenderanno a portarsi sui bordi del barilotto in quanto di diversa densità rispetto al liquido isolante, in questo modo i contatti saranno preservati da ogni tipo di corrosione e/o dispersione provocabile dall'acqua. Any residual water present inside the barrel once closed will tend to move to the edges of the barrel as of different density compared to the insulating liquid, in this way the contacts will be preserved from any type of corrosion and / or dispersion caused by the water.
Inoltre, la totale assenza di ossigeno impedisce anche qualsiasi rìschio di ossidazione che provocherebbe una riduzione della sezione conduttiva dei connettori e/o dei collegamenti elettrici. Furthermore, the total absence of oxygen also prevents any risk of oxidation which would cause a reduction in the conductive section of the connectors and / or electrical connections.
Le fasi installative sono sostanzialmente 6: The installation phases are basically 6:
1) intestazione dei cavi con inserimento nell’ordine di farfalla, gomma di tenuta e connettore; 1) cable header with insertion in the order of butterfly, sealing rubber and connector;
2) posa dei cavi opportunamente intestati sott'acqua; 2) laying of cables appropriately headed underwater;
3) inserimento dei cavi intestati nei rispettivi fori del tappo di chiusura e successivo serraggio dei cavi mediante la farfalla; 4) collegamento dei connettori intestati sui cavi; 3) insertion of the headed cables in the respective holes of the closing cap and subsequent tightening of the cables using the butterfly; 4) connection of the connectors headed on the cables;
5) apertura del barilotto in acqua e successivo inserimento delle teste dei cavi nel barilotto riempito di liquido isolante; 5) opening of the barrel in water and subsequent insertion of the heads of the cables into the barrel filled with insulating liquid;
6) serraggio del barilotto con il tappo di chiusura a tenuta. 6) tightening the barrel with the sealing cap.
