«SISTEMA PER SIGILLATURA SUPPLEMENTARE DI PASSAGGI POLARI SU BATTERIE INDUSTRIALI» "SYSTEM FOR ADDITIONAL SEALING OF POLAR PASSAGES ON INDUSTRIAL BATTERIES"

DESCRIZIONE DESCRIPTION

Settore dell’invenzione Invention sector

La seguente invenzione riguarda un sistema per sigillare i passaggi polari delle batterie elettriche industriali (prevalentemente al piombo) che hanno perso la tenuta sui passaggi polari medesimi, condizione che provoca la fuoriuscita dei vapori acidi (acido solforico). The following invention relates to a system for sealing the polar passages of industrial electric batteries (mainly lead) which have lost the seal on the polar passages themselves, a condition that causes the release of acid vapors (sulfuric acid).

Stato dell’arte State of the art

E’ noto che solitamente il problema si verifica a causa della deformazione dei poli in prossimità degli anelli di tenuta (originali). Conseguentemente anche a causa dei fenomeni galvanici, le connessioni si ossidano e si consumano velocemente provocando un aumento della resistenza elettrica sulle medesime. It is known that the problem usually occurs due to the deformation of the poles near the (original) sealing rings. Consequently, also due to galvanic phenomena, the connections oxidize and wear out quickly causing an increase in the electrical resistance on them.

Sommario dell’invenzione Summary of the invention

Con l’inserimento di una cuffia di tenuta in materiale elastico antiacido fra il polo ed il coperchio si ripristina una perfetta sigillatura. La cuffia, opportunamente pre-formata, esercita la tenuta sul polo, grazie all’elasticità al bordo di contatto ad angolo e sul coperchio per pressione, facilitata anche dal bordo morbido simile a quello di una ventosa. By inserting a sealing cap made of elastic antacid material between the pole and the cover, a perfect seal is restored. The cap, suitably pre-formed, holds the pole, thanks to the elasticity at the corner contact edge and on the pressure lid, also facilitated by the soft edge similar to that of a suction cup.

La cuffia viene tenuta a premere da un disco di materiale antiacido a sua volta mantenuto in posizione dalle stesse connessioni delle batterie. The cap is held to press by a disc of antacid material which is in turn held in place by the same connections as the batteries.

Sostituendo le connessioni elettriche e la bulloneria, contestualmente all’inserimento del sistema di sigillatura, si ottiene sia un notevole allungamento della vita media delle connessioni, sia una diminuzione delle perdite elettriche, con conseguente aumento della resa delle batterie. By replacing the electrical connections and nuts and bolts, simultaneously with the insertion of the sealing system, both a considerable lengthening of the average life of the connections and a decrease in electrical losses are obtained, with a consequent increase in the yield of the batteries.

Il sistema presenta il vantaggio di poter essere montato anche su batterie in esercizio (batterie con almeno due connessioni per polo), senza alcuna modifica sulle parti costituenti la batteria. The system has the advantage that it can also be mounted on batteries in operation (batteries with at least two connections per pole), without any modification to the parts making up the battery.

Inoltre può mantenere, grazie all’elevata elasticità, una perfetta tenuta anche nel caso di eventuali altre deformazioni. Moreover, thanks to its high elasticity, it can maintain a perfect seal even in the event of any other deformations.

- La fig.1 mostra un sistema secondo l’invenzione con i componenti in vista per una migliore descrizione, e a lavoro finito (particolare 8); - Fig. 1 shows a system according to the invention with the components in view for a better description, and when the work is finished (detail 8);

Descrizione dettagliata Detailed description

Con riferimento ai disegni allegati à ̈ descritto un sistema di sigillatura secondo l’invenzione. With reference to the attached drawings, a sealing system according to the invention is described.

Le parti di una batteria elettrica interessata dal sistema di sigillatura sono: The parts of an electric heater affected by the sealing system are:

coperchio della batteria (particolare (1)), polo di uscita (particolare (2)), ponticelli di connessione (particolare (3)). battery cover (detail (1)), output pole (detail (2)), connection jumpers (detail (3)).

Per montare il sistema di sigillatura in questione, si tolgono le connessioni (particolare (3)), si inserisce sul polo (particolare (2)), la cuffia in materiale elastico isolante (particolare (4)), la quale à ̈ pre-formata al centro con un diametro inferiore a quello del polo e quindi la sua tenuta à ̈ assicurata sul medesimo per elasticità (particolare (6)). To assemble the sealing system in question, the connections are removed (detail (3)), the cap in insulating elastic material (detail (4)) is inserted on the pole (detail (2)), which is formed in the center with a diameter smaller than that of the pole and therefore its tightness is ensured on the same by elasticity (detail (6)).

Poi si posiziona un disco di pressione (particolare (5)) e si rimontano le connessioni (particolare (3)). Then a pressure disc is positioned (detail (5)) and the connections are reassembled (detail (3)).

Il disco esercita una spinta sulla cuffia, che viene tenuta a premere sul coperchio (particolare (7)). The disc exerts a push on the cap, which is forced to press on the lid (detail (7)).

Terminate queste operazioni si ha una perfetta sigillatura del passaggio polare. Once these operations have been completed, the polar passage is perfectly sealed.

Vista di come si presenta il lavoro finito (particolare (8)). View of how the finished work looks (detail (8)).
