Description

i 146334in 146334

Opfindelsen angår en strømforsyningsenhed til en signalkilde til brug på vandet, indeholdende et batteri til strømforsyning af en signalkilde samt koblermidler til at koble batteriet til signalkilden.The invention relates to a power supply unit for a signal source for use on the water, containing a battery for supplying a signal source and coupling means for connecting the battery to the signal source.

5 Der kendes strømforsyningsenheder afdsn omhandlede art, hvor koblermidlerne udgøres af en sædvanlig mekanisk kobler, der skal betjenes, før der føres strøm til signalkilden, der sædvanligvis udgøres af en lyskilde, men også kan være en anden form for signalkilde, f.eks.There are known power supply units of the kind in which the coupling means are constituted by a conventional mechanical coupler which must be operated before supplying power to the signal source, usually constituted by a light source, but may also be another form of signal source, e.g.

10 en radiosender. I denne type af strømforsyningsenheder kræves der en aktiv indsats fra en person.10 and a radio transmitter. This type of power supply unit requires active effort from a person.

Det er også kendt at anvende vandaktiverede batterier, der aktiveres, når der trænger vand ind i batteriet, der herved forsynes med elektrolyt, der enten kan ud-15 gøres af selve det indtrængende havvand eller fremkommer, når det indtrængende vand opløser i batteriet værende saltkrystaller. Et sådant batteri virker automatisk, når det kommer i vand, men da det skal være forhindret i at blive aktiveret af utilsigtet indtrængende fugtighed, må 20 der findes ret snævre kanaler til vandet. Sådanne kanaler bliver let tilstoppet under batteriets opbevaring, og de forårsager under alle omstændigheder en forsinket aktivering, specielt i det tilfælde, hvor der skal opløses saltkrystaller.It is also known to use water-activated batteries which are activated when water enters the battery, which is provided with electrolyte, which can either be made up of the seawater itself or emerge when the penetrating water dissolves in the salt-crystals of the battery. . Such a battery works automatically when it gets into water, but since it must be prevented from being activated by unintentionally penetrating moisture, there must be quite narrow channels to the water. Such channels are easily clogged during battery storage and in any case cause a delayed activation, especially in the case of salt crystals having to dissolve.

25 Med den foreliggende opfindelse tilsigtes tilveje bragt en strømforsyningsenhed, der uden menneskers indgriben med sikkerhed fungerer og dermed strømforsyner signalkilden, i samme øjeblik den kommer under vand.The present invention is intended to provide a power supply unit which operates without human intervention with certainty and thus power the signal source as soon as it comes underwater.

Dette opnås ifølge opfindelsen ved, at batteriet 30 og koblermidlerne er anbragt i en vandtæt beholder, der på ydersiden har to blottede elektroder, og at koblermidlerne udgøres af en elektronisk kobling, der er forbundet med batteriet, elektroderne og tilledninger til signalkilden, og som er således indrettet, at signal-35 kilden strømforsynes fra batteriet, når beholderen ned-dyppes i vand. Så snart vandet berører de to blottede elektroder, ændres den ydre modstand mellem disse, og dette påvirker den elektroniske kobling, så der øjeblik- 146334 2 kelig føres strøm til signalkilden.This is achieved according to the invention by the fact that the battery 30 and the coupling means are arranged in a waterproof container having on the outside two exposed electrodes and that the coupling means are an electronic coupling connected to the battery, the electrodes and leads to the signal source, which are so arranged that the signal source is powered from the battery when the container is immersed in water. As soon as the water touches the two exposed electrodes, the external resistance between them changes and this affects the electronic coupling so that current is immediately fed to the signal source.

Strømforsyningsenheden ifølge opfindelsen kan f.eks. anvendes i en nødbøje af den art, der normalt er koblet sammen med en redningskrans. Da en sådan bøje opbevares 5 udendørs, er det væsentligt, at den elektroniske kobling ikke aktiveres af tilfældigt vand, f.eks. regnvand.The power supply unit according to the invention can e.g. is used in an emergency buoy of the kind normally coupled with a life rope. Since such a buoy is stored outdoors, it is essential that the electronic coupling is not activated by random water, e.g. rainwater.

Derfor anbringes elektroderne i en sådan bøje hensigtsmæssigt på en sådan måde, at ovenfra kommende vand ikke kan trænge ind til elektroderne.Therefore, the electrodes in such a buoy are conveniently arranged in such a way that the water coming from above cannot penetrate the electrodes.

10 I strømforsyningsenheden ifølge opfindelsen anven des hensigtsmæssigt et lithiumbatteri, da dette giver en højere spænding og har en større energitæthed end f.eks. almindelige tørelementer.In the power supply unit according to the invention, a lithium battery is suitably used since this gives a higher voltage and has a higher energy density than e.g. common dry elements.

Opfindelsen forklares nærmere i det følgende under 15 henvisning til den skematiske tegning, hvor fig. 1 viser et koblingsdiagram over den elektroniske kobling til en strømforsyningsenhed ifølge opfindelsen,.The invention will be explained in more detail below with reference to the schematic drawing, in which fig. 1 shows a wiring diagram of the electronic coupling to a power supply unit according to the invention.

fig. 2 en nødlygte med en strømforsyningsenhed 20 ifølge opfindelsen, fig. 3 en nødbøje med en sådan strømforsyningsenhed, og fig. 4 en redningsflåde med en sådan strømforsyningsenhed.FIG. 2 shows an emergency lamp with a power supply unit 20 according to the invention; FIG. 3 shows an emergency buoy with such a power supply unit, and FIG. 4 shows a life raft with such a power supply unit.

25 Den i fig. 1 viste kobling indeholder et batteri 1, fortrinsvis et lithiumbatteri, der er bestemt til at strømforsyne en signalkilde, der i det foreliggende tilfælde er vist som en lyskilde 2, der er indskudt i kol-lektor-emitterkredsen for en transistor 3. Dennes ba-30 sis er over en passende modstand 4 forbundet med emit-teren i en anden transistor 5, hvis kollektor er forbundet med batteriets positive klemme. Denne transistors basis er over en stor modstand 6 forbundet med batteriets negative klemme. Den er endvidere forbundet med 35 den ene af strømforsyningsenhedens to blottede elektroder 7, hvoraf den anden 8 er forbundet med batteriets positive klemme.The embodiment of FIG. 1, a battery 1, preferably a lithium battery, intended to power a signal source shown in the present case as a light source 2 inserted in the collector-emitter circuit of a transistor 3. 30 sis is connected to the emitter in a second transistor 5, the collector of which is connected to the positive terminal of the battery via a suitable resistor 4. The base of this transistor is over a large resistor 6 connected to the negative terminal of the battery. It is further connected to 35 one of the two exposed electrodes 7 of the power supply unit, the other 8 of which is connected to the positive terminal of the battery.

Den i fig. 1 viste kobling, inklusive batteriet 1, er anbragt i en vandtæt beholder, og de to elektroder 7 og 8 er blottede på beholderens yderside.The FIG. 1, including the battery 1, is placed in a waterproof container and the two electrodes 7 and 8 are exposed on the outside of the container.

Sålænge beholderen ikke er neddyppet i vand, er der 5 en stor modstand mellem klemmerne 7 og 8, således at basis i transistoren 5 er i det væsentlige på samme potential som batteriets negative klemme. Begge transistorer 3 og 5 er derfor spærrede, og lampen 2 lyser ikke. Hvis strømforsyningsenheden neddyppes i vand, 10 formindskes modstanden mellem elektroderne 7 og 8 væsentligt, hvorved begge transistorerne 3 og 5 bliver i det mindste delvis ledende, således at lampen 2 nu lyser.As long as the container is not immersed in water, there is a high resistance between terminals 7 and 8, so that the base of the transistor 5 is essentially at the same potential as the negative terminal of the battery. Both transistors 3 and 5 are therefore blocked and lamp 2 is not lit. If the power supply unit is immersed in water, the resistance between the electrodes 7 and 8 is substantially reduced, whereby both transistors 3 and 5 become at least partially conductive, so that the lamp 2 now lights up.

Pig. 2 viser en nødlygte, der f.eks. kan anvendes 15 i forbindelse med en redningsvest, idet den anbringes i en lomme på en sådan vest eller bindes til denne. I en vandtæt beholder 9 er der anbragt en elektronisk kobling med tilhørende batteri, f.eks. indrettet som vist i fig. 1, og de to elektroder 7 og 8 rager ud gen-20 nem beholdervæggen. De kan f.eks. udgøres af skruer, der er skruet gennem beholdervæggen med skruehovederne beliggende uden på beholderen. Lyskilden 2 er anbragt oven på beholderen.Pig. 2 shows an emergency lamp which e.g. may be used in connection with a life jacket, being placed in a pocket on such a vest or tied to it. In an watertight container 9, an electronic coupling with associated battery is provided, e.g. arranged as shown in FIG. 1, and the two electrodes 7 and 8 protrude through the container wall. For example, they can is made up of screws screwed through the container wall with the screw heads located on the outside of the container. The light source 2 is placed on top of the container.

Hvis en person, der bærer en redningsvest med en 25 nødlygte som vist i fig. 2, falder i vandet, vil lyskilden 2 straks give sig til at lyse, selv om personen er bevidstløs eller ikke sanser at tænde lygten.If a person wearing a life jacket with an emergency light as shown in FIG. 2, falling into the water, the light source 2 will immediately light up, even if the person is unconscious or does not sense to turn on the lamp.

I fig. 3 er vist en nødbøje af den type, der f.eks. anvendes i forbindelse med redningskranse, og som er be-30 stemt til at blive kastet i vandet sammen med en sådan krans. Bøjen har en i et cylindrisk hus 10 anbragt batterienhed, der f.eks. kan være som vist i fig. 1.In FIG. 3 shows an emergency buoy of the type which e.g. is used in conjunction with rescue garlands and which are intended to be thrown into the water together with such a garland. The buoy has a battery unit arranged in a cylindrical housing 10 which e.g. may be as shown in FIG. First

Oven over huset 10 findes et flydelegeme 11, der på toppen bærer lyskilden 2. De to elektroder 7 og 8 35 findes i bunden af det cylindriske hus 10, hvis cylindriske ydervæg når længere ned end den flade, hvorpå elektroderne 7 og 8 findes. Herved undgås, at regnvand kan bevirke tænding af lyskilden, selv om bøjenAbove the housing 10 is a floating body 11 carrying on top the light source 2. The two electrodes 7 and 8 35 are located at the bottom of the cylindrical housing 10, whose cylindrical outer wall extends further than the surface on which the electrodes 7 and 8 are located. This prevents rainwater from igniting the light source, even if the buoy
