Description
Oppfinnelsen vedrører en akkumulator, særlig blyakkumulator, fortrinnsvis for nytte- kjøretøy, med et hus med flere celler, samt med et lokk for huset, i hvilket lokk det mellom en underdel og en dertil i avstand anordnet overdel er utformet et labyrintaktig hulrom for syreutskilling, idet lokkets underdel som basislokk har en traulignende fordypning, hvorpå lokkets overdel settes og forbindes, hvilket lokk videre har en avgassingsåpning med en antennelsesbeskyttelse samt eventuelle lukkbare fylle- og kontroll-åpninger for cellene. The invention relates to an accumulator, in particular a lead accumulator, preferably for commercial vehicles, with a housing with several cells, as well as with a lid for the housing, in which lid a labyrinth-like cavity for acid secretion is formed between a lower part and an upper part arranged at a distance from it, as the lower part of the lid as a base lid has a trough-like recess, on which the upper part of the lid is placed and connected, which lid further has a degassing opening with an ignition protection as well as any closable filling and control openings for the cells.
En blyakkumulator av denne type er kjent fra DE-GM 84 30 246. Den består av et kunststoffhus, hvor det er anordnet flere celler, vanligvis seks celler. Huset med cellene er lukket med et lokk, som settes på huset. Lokket består av en basisdel og en i en avstand dertil anordnet lokkdel, slik at det mellom dem dannes et hulrom for syreutfell ing. For lufting av de under blyakkumulatorens bruk oppstående gasser, er lokket forsynt med en avgassingsåpning, med en antennelsesbeskyttelse i form av en flammesikt-ventil. Dessuten har den kjente blyakkumulator en fyllings- og kontrollåpning for hver celle. Disse åpninger kan lukkes med en respektiv propp. A lead accumulator of this type is known from DE-GM 84 30 246. It consists of a plastic housing, in which several cells are arranged, usually six cells. The housing with the cells is closed with a lid, which is placed on the housing. The lid consists of a base part and a lid part arranged at a distance from it, so that a cavity is formed between them for acid precipitation. For venting the gases arising during the use of the lead accumulator, the lid is equipped with a degassing opening, with an ignition protection in the form of a flame detection valve. In addition, the known lead accumulator has a filling and control opening for each cell. These openings can be closed with a respective plug.
Den kjente blyakkumulator med i lokket integrert avgassingssystem samt med antennelsesbeskyttelse har en uønsket.stor høyde. Blyakkumulatoren krever derfor mye plass, slik at dens anvendelsesmuligheter derved innsnevres. Det er særlig i nyttekjøretøy at den store høyden representerer en ulempe. The known lead accumulator with an integrated degassing system in the lid and with ignition protection has an undesirably large height. The lead accumulator therefore requires a lot of space, so that its application possibilities are thereby narrowed. It is particularly in commercial vehicles that the great height represents a disadvantage.
Hensikten med oppfinnelsen er å tilveiebringe en akkumulator, særlig en blyakkumulator, fortrinnsvis for nyttekjøretøy, med et lavere lokk. The purpose of the invention is to provide an accumulator, in particular a lead accumulator, preferably for commercial vehicles, with a lower lid.
Ifølge oppfinnelsen foreslås det derfor en akkumulator som nevnt innledningsvis, kjennetegnet ved at lokkets overdel i form av en lokkplate i hovedsaken flukter med oversiden av baslslokket i påsatt tilstand og at dybden til den traulig nende fordypning (6) er større enn høyden til en på undersiden omløpende kant på baslslokket, med hvilken kant basislokket er festet til huset. Det i lokket dannede hulrom vil således være delvis nedsenket i akkumulatorhuset, hvilket medfører en ytterligere optimalisering av lokkets flate utførelse. According to the invention, it is therefore proposed an accumulator as mentioned in the introduction, characterized by the fact that the upper part of the lid in the form of a lid plate is essentially flush with the upper side of the base lid when fitted and that the depth of the reliable recess (6) is greater than the height of one on the underside surrounding edge of the base cover, with which edge the base cover is attached to the housing. The cavity formed in the lid will thus be partially submerged in the accumulator housing, which entails a further optimization of the lid's flat design.
Et ifølge denne tekniske lære utformet lokk for en blyakkumulator utmerker seg ved at det er meget lavt, slik at blyakkumulatorens plassbehov i vertikalretningen reduseres til et minimum. Dette medfører at blyakkumulatoren blir særlig egnet for bruk i nyttekjøretøy-sektoren. Den trauformede fordypning i basislokket vil i hovedsaken definere hulrommet og vil i hovedsaken oppta alle de deler som er nødvendig for syreutfellingen. Befestigelsen av lokkplaten på basislokket kan skje ved hjelp av sveising, særlig ved hjelp av varmeelementsveising, eller på annen måte. Basislokket har en åpning for fylling, lufting og tilbakeløp av syren for hver enkelt celle. Ved klargjøring av batteriet fremstiller man første lokket, idet lokkplaten festes på basislokket på den foran nevnte måte. Ved hjelp av det på denne måten tilveiebragte lokk kan man så gjennomføre en separat tetthetsprøving av hele avgassingsområdet i lokket. Er denne prøven positiv, så festes det komplette lokk på akkumulatorhuset, hvoretter det gjennomføres en tetthetsprøving av de enkelte celler. En på denne måten utformet akkumulator har et flatt lokk slik at akkumulatoren lett kan stables og også blir overflømmingssikker. Man kan uten problemer foreta en påfølgende fylling av akkumulatoren med elektrolytt. A lid designed according to this technical teaching for a lead accumulator is distinguished by the fact that it is very low, so that the space requirement of the lead accumulator in the vertical direction is reduced to a minimum. This means that the lead accumulator is particularly suitable for use in the commercial vehicle sector. The trough-shaped depression in the base lid will mainly define the cavity and will mainly occupy all the parts necessary for the acid precipitation. The attachment of the lid plate to the base lid can be done by means of welding, in particular by means of heating element welding, or in another way. The base lid has an opening for filling, venting and reflux of the acid for each individual cell. When preparing the battery, the lid is first prepared, with the lid plate attached to the base lid in the manner mentioned above. With the help of the lid provided in this way, a separate tightness test of the entire degassing area in the lid can then be carried out. If this test is positive, the complete lid is attached to the accumulator housing, after which a tightness test is carried out on the individual cells. An accumulator designed in this way has a flat lid so that the accumulator can be easily stacked and is also floodproof. You can easily carry out a subsequent filling of the accumulator with electrolyte.
Ifølge en fordelaktig videreutvikling foreslås det at det i den trauformede fordypning såvel som på undersiden av lokkplaten skal være utformet med hverandre korresponderende ribber, som for det første danner en labyrint og for det andre gir en innbyrdes avstøtting, slik at lokket stabili-seres. Man kan således på en teknisk sett meget enkel måte oppnå et meget funksjonsdyktig lokk, som har en optimal syreutfelling og en optimal stabilitet. Labyrint-ribbene danner dessuten barrierer for syre i cellene, når akkumulatoren eventuelt vippes. According to an advantageous further development, it is proposed that in the trough-shaped depression as well as on the underside of the lid plate corresponding ribs should be designed, which firstly form a labyrinth and secondly provide mutual repulsion, so that the lid is stabilized. You can thus, in a technically very simple way, achieve a very functional lid, which has an optimal acid precipitation and an optimal stability. The labyrinth ribs also form barriers for acid in the cells, when the accumulator is possibly tilted.
Ifølge oppfinnelsen foreslås det også at akkumulatorens According to the invention, it is also proposed that the accumulator's
polgjennomføringer skal ligge i et lokkområde som ikke dekkes av lokkplaten. Derved vil det i lokkplateområdet fremkomme en plan overflate, hvor eksempelvis festeelementer kan anordnes, uten at polene forstyrrer. Dessuten kan det også realiseres pole bushings must be located in a cover area that is not covered by the cover plate. Thereby, a flat surface will appear in the lid plate area, where, for example, fastening elements can be arranged, without the poles interfering. Moreover, it can also be realized
en meget god stableevne for akkumulatoren. a very good stackability for the accumulator.
Ifølge oppfinnelsen foreslås det også at bunnen i den trauformede fordypning i de enkelte celleområder skal være traktformet i retning mot celleåpningen, for fylling, lufting og retur av syre. Samtlige strømningsflater for den respektive celle vil således ha et fall, med celleåpningen som det laveste punkt, slik at kondensert syre som samler seg i hulrommet, uten problemer kan gå tilbake til den respektive celle. According to the invention, it is also proposed that the bottom of the trough-shaped recess in the individual cell areas should be funnel-shaped in the direction towards the cell opening, for filling, aeration and return of acid. All flow surfaces for the respective cell will thus have a drop, with the cell opening as the lowest point, so that condensed acid that collects in the cavity can return to the respective cell without problems.
Ifølge oppfinnelsen foreslås det videre at det på undersiden av basislokket er utformet støttelementer som ligger mot platepakken i den respektive celle og virker avstøttende. Derved oppnås en sikker fiksering av platepakkene i cellene, slik at det muliggjøres en mest mulig forstyrrelsesfri drift, særlig under høye mekaniske påkjenninger. According to the invention, it is further proposed that support elements are formed on the underside of the base lid which lie against the plate pack in the respective cell and act as a support. This achieves a secure fixation of the plate packs in the cells, so that the most possible disturbance-free operation is possible, especially under high mechanical stress.
Ifølge oppfinnelsen foreslås det også at cellene skal være anordnet I flere, fortrinnsvis to rader, som er skilt fra hverandre ved hjelp av en skillevegg og med en avgasningsåpning i den respektive ende, hvilken avgasningsåpning er forsynt med en antennelsesbeskyttelse. Avgassingen eller luftingen skjer således fra celle til celle, hvorved den ved enden av hver rad anordnede lufteåpning definerer en sentrallufting. På grunn av den lange strekningen frem til lufteåpningen vil en stor del av syren felles ut igjen og gå tilbake. According to the invention, it is also proposed that the cells should be arranged in several, preferably two rows, which are separated from each other by means of a partition and with a degassing opening at the respective end, which degassing opening is provided with an ignition protection. The degassing or aeration thus takes place from cell to cell, whereby the air opening arranged at the end of each row defines a central air. Due to the long distance to the air opening, a large part of the acid will precipitate out and return.
Ifølge oppfinnelsen foreslås det også at platepakkene skal være anordnet etter hverandre i cellene i den respektive rad. Det vil si at platene, som danner platepakkene, skal være rettet inn parallelt med husets lengdesidevegg, slik at altså platene i platepakkene strekker seg i radens lengderetning. According to the invention, it is also proposed that the plate packs should be arranged one after the other in the cells in the respective row. This means that the plates, which form the plate packs, must be aligned parallel to the house's longitudinal side wall, so that the plates in the plate packs extend in the longitudinal direction of the row.
Antennelsesbeskyttelsen innbefatter fortrinnsvis et forkammer og et etterkammer. Dette sikrer en optimal gjennomgang av syregassene gjennom antennelsesbeskyttelsen. Fra etterkammeret går gassene ut av akkumulatoren. The ignition protection preferably includes a pre-chamber and an after-chamber. This ensures an optimal passage of the acid gases through the ignition protection. From the after chamber, the gases exit the accumulator.
Ifølge oppfinnelsen foreslås det at antennelsesbeskyttelsen utføres slik at det i tilslutning til den er utformet en luftekanal i basislokket. Gassene vil således gå ut gjennom denne luftekanal. According to the invention, it is proposed that the ignition protection is carried out so that an air duct is designed in connection with it in the base lid. The gases will thus exit through this air duct.
For at gassene ikke skal gå ukontrollert ut fra akkumulatoren, kan fortrinnsvis en lufteslange for fjerning av gassen knyttes til luftekanalen. In order for the gases not to escape uncontrolled from the accumulator, an air hose for removing the gas can preferably be connected to the air duct.
Luftekanalen kan ifølge oppfinnelsen utformes med en helling. Ifølge oppfinnelsen kan luftekanalen også utføres slik at den går skrått mot husets sidevegg med hensyn på radens lengdeutstrekning. Dessuten gis fordelaktig de til radene tilordnede luftekanaler innbyrdes forbindelse, slik at man derved kan få realisert en utligning. According to the invention, the air duct can be designed with a slope. According to the invention, the air duct can also be designed so that it runs diagonally towards the side wall of the house with regard to the length of the row. In addition, the air ducts assigned to the rows are advantageously interconnected, so that an equalization can thereby be realized.
Dessuten foreslås det at antennelsesbeskyttelsen skal være en skrått anordnet flammesikt. Det medfører den fordel at ved en eventuell avvanning av flammesikten vil de utskilte partikler strømme til flammesiktkammerets bunn, hvorfra det muliggjøres en tilbakeføring til cellene. Man vil således være sikret en lufting av akkumulatoren og dessuten hindres en tilstopping av flammesiktens poreåpninger. Flammesiktene er anordnet redundant. In addition, it is proposed that the ignition protection should be an obliquely arranged flame screen. This has the advantage that, in the event of dewatering of the flame sieve, the separated particles will flow to the bottom of the flame sieve chamber, from where it is possible to return them to the cells. One will thus be assured of aeration of the accumulator and, moreover, clogging of the flame screen's pore openings is prevented. The flame sights are arranged redundantly.
De foran beskrevne fordelaktige videreutviklinger av . oppfinnelsen representerer alle i og for seg selvstendige inventive ideer, som ikke nødvendigvis er knyttet til lokkets flate byggemåte. The previously described advantageous further developments of . the invention represents all in and of itself independent inventive ideas, which are not necessarily linked to the lid's flat design.
Oppfinnelsen skal nå beskrives nærmere undfer henvisning til tegningene hvor det er vist en blyakkumulator ifølge oppfinnelsen, med et integrert avgassingssystem og med en beskyttelse mot antennelse utenfra. The invention will now be described in more detail with reference to the drawings, where a lead accumulator according to the invention is shown, with an integrated degassing system and with a protection against ignition from the outside.

Blyakkumulatoren består av et hus 1 av kunststoff, med totalt seks celler anordnet i to rader. Cellespenningen tas ut over to poler 2. The lead accumulator consists of a housing 1 made of plastic, with a total of six cells arranged in two rows. The cell voltage is taken out over two poles 2.
Det oppad åpne hus 1 kan lukkes med et lokk 3, som likeledes er av termoplastisk kunststoff. Lokket 3 er satt sammen av et basislokk 4 og en lokkplate 5. Som snittet i fig. 3 viser, har basislokket 4 en trauformet fordypning 6. Denne er på oversiden lukket slik ved hjelp av lokkplaten 5 at lokkplaten flukter jevnt med basislokkets 4 overside. Mellom basislokket 4 og lokkplaten 5 defineres det således et hulrom 7 for syre utfelling samt for lufting av blyakkumulatoren. Lokket 3 festes på huset 1 derved at lokkets basisdel eller basislokket 4 sveises sammen med husets 1 overkant ved hjelp av den på basislokket på undersiden omløpende kant 8. The upwardly open housing 1 can be closed with a lid 3, which is also made of thermoplastic plastic. The lid 3 is assembled from a base lid 4 and a lid plate 5. As the section in fig. 3 shows, the base lid 4 has a trough-shaped recess 6. This is closed on the upper side in such a way that the lid plate aligns evenly with the upper side of the base lid 4. Between the base lid 4 and the lid plate 5, a cavity 7 is thus defined for acid precipitation and for venting the lead accumulator. The lid 3 is attached to the housing 1 by welding the base part of the lid or the base lid 4 together with the upper edge of the housing 1 using the surrounding edge 8 on the base lid on the underside.
I basislokket 4 er det i de områder som ikke er dekket av lokkplaten 5 anordnet en polgjennomføring 9 for polene 2. Som antydet i fig. 2 med den kvadratiske skravering kan området ved polene 2 være berøringsbeskyttet ved hjelp av en enhetlig kappe 10. Denne er utformet som en påstikkbar del og kan bringes til forskjellige stillinger for derved å lette tilkoplingen av akkumulator-kablene. Kappen 10 kan sperres både i dekkstilling og i en oppsvingt adgangsstilling. In the base cover 4, in the areas that are not covered by the cover plate 5, a pole lead-through 9 for the poles 2 is arranged. As indicated in fig. 2 with the square hatching, the area at the poles 2 can be protected from contact by means of a uniform cover 10. This is designed as a plug-in part and can be brought to different positions to thereby facilitate the connection of the accumulator cables. The cover 10 can be locked both in the cover position and in an upturned access position.
Hver av de seks cellene har en i basislokket 4 utformet åpning 11 for fylling av cellene, lufting såvel som retur av syre. Åpningen 11 er utformet med en i cellen nedragende målestav 12, som tjener som anviser for det maksimale syrenivå. Basislokket 4 er i området ved åpningen 11 traktformet, idet samtlige nedrenningsflater 13 har et fall med det laveste punkt i åpningen 11, slik at det derved er tilveiebragt et tilbakeløp for kondensert syre. Rundt åpningen 11 er det anordnet et ringformet beskyttelsessteg 14. Ved en eventuell kortvarig vipping av akkumulatoren vil dette steg holde syren tilbake, slik at bare en liten mengde vil trenge inn i det mellom basislokket 4 og lokkplaten 5 dannede, kammerlignende hulrom 7. Tilbakeholdingen forsterkes ved at det mellom basislokket 4 og lokkplaten 5 er anordnet ribber 15. Each of the six cells has an opening 11 formed in the base lid 4 for filling the cells, aeration as well as the return of acid. The opening 11 is designed with a measuring rod 12 extending down into the cell, which serves as an indicator for the maximum acid level. The base lid 4 is funnel-shaped in the area of the opening 11, with all downflow surfaces 13 having a slope with the lowest point in the opening 11, so that a return flow for condensed acid is thereby provided. An annular protective step 14 is arranged around the opening 11. In the event of a brief tilting of the accumulator, this step will hold the acid back, so that only a small amount will penetrate into the chamber-like cavity 7 formed between the base lid 4 and the lid plate 5. The retention is reinforced in that ribs 15 are arranged between the base lid 4 and the lid plate 5.
I lengderetningen forløpende, steglignende ribber 16 vil oppfange spennkrefter som fremkommer ved fastmonteringen av akkumulatoren via lokket 3. Running in the longitudinal direction, step-like ribs 16 will absorb tension forces that occur when the accumulator is fixed via the lid 3.
Lokket 3 har et integrert luftesystem. I utførelseseksempelet er det i samsvar med de to cellerader utformet to uavhengig av hverandre virkende luftesystemer. For å muliggjøre dette er det mellom de to rader anordnet en midtre skillevegg 17, som skiller de to rader gasstett fra hverandre. Luftingen av de to rader skjer fra celle til celle. Gassen strømmer herunder gjennom åpningene 11 og inn i hulrommet 7 mellom basislokket 4 og lokkplaten 5. Etter passeringen av lufte-hullene 18 mellom cellene går gassen gjennom en labyrint 19 og inn i et forkammer 20 i en antennelsesbeskyttelse 21. Antennelsesbeskyttelsen har et etterkammer 22. Fra forkammeret går gassene gjennom en åpning 23 i basislokket, gjennom antennelsesbeskyttelsen 21, her i form av en flammesikt, og inn i etterkammeret 22. Antennelsesbeskyttelsen 21 er i opptak 24 forbundet med opptakskanter 25 i basislokket 4. Antennelsesbeskyttelsen 21 gir en beskyttelse mot antennelse utenfra. At såvel forkammerne 20 som etter-kammerne 22 i de to rader har respektive innbyrdes forbindelse, og det faktum at det forefinnes to antennelsesbe-skyttelser 21, gir en flerdoblet luftesikkerhet. Da flammesikten i antennelsesbeskyttelsen 21 er anordnet på skrått, vil man være sikret at ved en eventuell gjennomfuktlg av flammesikten vil de utskilte partikler strømme mot bunnen 26 i forkammeret 20 og videre via avrenningsflåtene 13 og åpningene 11 tilbake til cellene. Da flammesiktens poreåpninger således ikke tilstoppes, oppnås en ytterligere sikker avgassing eller lufting. Lid 3 has an integrated ventilation system. In the design example, in accordance with the two rows of cells, two air systems acting independently of each other have been designed. To make this possible, a middle partition wall 17 is arranged between the two rows, which separates the two rows gas-tight from each other. The ventilation of the two rows takes place from cell to cell. The gas flows below through the openings 11 and into the cavity 7 between the base cover 4 and the cover plate 5. After passing through the ventilation holes 18 between the cells, the gas passes through a labyrinth 19 and into a pre-chamber 20 in an ignition protection 21. The ignition protection has an after-chamber 22. From the pre-chamber, the gases pass through an opening 23 in the base lid, through the ignition protection 21, here in the form of a flame screen, and into the after-chamber 22. The ignition protection 21 is connected in the intake 24 to the intake edges 25 in the base lid 4. The ignition protection 21 provides protection against ignition from the outside . The fact that both the pre-chambers 20 and the after-chambers 22 in the two rows have respective interconnections, and the fact that there are two ignition protections 21, provides a multifold air safety. As the flame screen in the ignition protection 21 is arranged at an angle, it will be ensured that if the flame screen becomes wet, the secreted particles will flow towards the bottom 26 in the antechamber 20 and further via the run-off rafts 13 and the openings 11 back to the cells. As the flame screen's pore openings are thus not blocked, further safe degassing or aeration is achieved.
Fra etterkammeret 22 i den respektive cellerad føres gassene gjennom lufteåpningene og ut fra akkumulatoren gjennom luftekanalene 27. Disse luftekanaler 27 er, som vist i snittet i fig. 4, utformet med helling samt med skråning mot husets 1 lengdesidevegg. Videre er de forsynt med en standard tilkopling 28, slik at gassene kan føres bort på en kontroll-ert måte gjennom tilkoplede slanger. From the after-chamber 22 in the respective cell row, the gases are led through the air openings and out of the accumulator through the air ducts 27. These air ducts 27 are, as shown in the section in fig. 4, designed with a slope and with a slope towards the house's 1 longitudinal side wall. Furthermore, they are provided with a standard connection 28, so that the gases can be led away in a controlled manner through connected hoses.
Hver celle har en fylle- og serviceåpning 29. Denne kan lukkes ved hjelp av en propp, med en tilhørende pakning 31. Each cell has a filling and service opening 29. This can be closed by means of a plug, with an associated gasket 31.
I snittet i fig. 3 er platepakkene 32 i de enkelte celler antydet. Platepakkene er avstøttet ved hjelp av et respektivt støtteelement 33. Forbindelsen mellom støtteelementene 33 og basislokket 4 skjer i en utsparing 34 ved hjelp av tilsvar-ende anordnede ribber 35. In the section in fig. 3, the plate packages 32 in the individual cells are indicated. The plate packages are supported by means of a respective support element 33. The connection between the support elements 33 and the base lid 4 takes place in a recess 34 by means of correspondingly arranged ribs 35.
Den viste akkumulator utmerker seg ved at den har et ekstremt flatt og i høyden lite plasskrevende lokk 3. Dessuten har den en stor vippesikkerhet (90°) i lengderetningen, uten fare for en ukontrollert utstrømming av syre. Den spesielle anordning av ombøyningssteg 36 gir en ekstra syrebeskyttelse for antennelsesbeskyttelsen 21, og det oppnås således en særlig høy vippesikkerhet for akkumulatoren. Akkumulatoren kan fordelaktig anvendes i nyttekjøretøy, som start og drivbatteri. Akkumulatoren er imidlertid ikke begrenset til slik spesiell anvendelse, men kan benyttes overalt der hvor man har behov for en akkumulator, da særlig med et lavt og lite plasskrevende lokk og med høy vippesikkerhet. The accumulator shown is distinguished by the fact that it has an extremely flat lid 3 that takes up little space in height. It also has great tilting safety (90°) in the longitudinal direction, without the risk of an uncontrolled outflow of acid. The special arrangement of bending step 36 provides an additional acid protection for the ignition protection 21, and a particularly high tipping safety is thus achieved for the accumulator. The accumulator can advantageously be used in commercial vehicles, as a starter and drive battery. However, the accumulator is not limited to such a special application, but can be used wherever there is a need for an accumulator, especially with a low and space-saving lid and with high tilting safety.
