Description
Foreliggende oppfinnelse har til hensikt å kunne fremstille et system som automatisk gir signaler om maskebrudd i en mære forarbeidet av not eller lignende materiale. Oppfinnelsen er kon-struert med henblikkpå bruk i mæren for laks, smolt o.l., men kan selvsakt benyttes i andre mærer og for andre levende mari-time arter. The present invention aims to be able to produce a system which automatically gives signals about mesh breakage in a mare prepared from groove or similar material. The invention is designed with a view to use in the sea for salmon, smolt etc., but can of course be used in other seas and for other living maritime species.
Det er en kjent sak at det årlig går tapt store mengder oppdrett-fisk som på grunn av maskebrudd får fri passasje ut av mæren. Slike brudd er vanskelig, for ikke å si umulig, å oppdage i tide slik at en kan treffe tiltak for å begrense utstrømningen av kostbar fisk. Det har derfor vært et stort ønske i oppdretts-næringen å komme frem til anordninger som i størst mulig ut-strekning var istand til å gi siglaler om "hull" i mæren. It is a well-known fact that large quantities of farmed fish are lost every year, which are allowed free passage out of the dam due to broken mesh. Such breaches are difficult, if not impossible, to detect in time so that measures can be taken to limit the outflow of valuable fish. There has therefore been a great desire in the farming industry to come up with devices which, to the greatest extent possible, were able to give signs of "holes" in the mare.
Etter foreliggende oppfinnelse mener en å ha kommet frem til et system som ved praktiske forsøk har vist gode resultater. According to the present invention, one believes to have arrived at a system which has shown good results in practical tests.
Det nye og karakteristiske ved oppfinnelsen er at selve tråden, som noten eller deler av denne er forarbeidet av, i sin kjerne har innspunnet en strømførende isolert ledning som ved brudd i masken og dermed i den strømførende ledning avgir tilstrekkelig elektrisk innpuls til å påvirke hosstående rundt mæren anordnede elektroder som er innrettet for å overføre impulser visuelt som lys- eller lydsignaler ved hjelp av eksempelvis telefon eller annet kommunikasjonsmiddel. Den strømførende ledning som er en del av masketråden, for hver eller annet hver maskefar er samlet i en vertikal pølse og ført opp til overflaten hvor den er tilkoblet en strømkilde. Ved maskebrudd i noten eller mæren oppfanges signaler fra disse ved hjelp av et nærmere bestemt antall og typer elektroder som senkes ned og plasseres rundt mæren. Signalene kan nå overføres visuelt som lyssignaler eller lydsignaler eksempelvis ved hjelp av telefon. The new and characteristic feature of the invention is that the thread itself, from which the groove or parts of it is processed, has a current-carrying insulated wire spun into its core which, when the mesh and thus the current-carrying wire breaks, emits a sufficient electrical input pulse to affect the surrounding electrodes arranged in the mær are designed to transmit impulses visually as light or sound signals using, for example, a telephone or other means of communication. The current-carrying wire that is part of the mesh thread, for each or every mesh father, is collected in a vertical sausage and brought up to the surface where it is connected to a power source. In the event of a mesh break in the groove or the core, signals from these are picked up using a specific number and types of electrodes that are lowered and placed around the core. The signals can now be transmitted visually as light signals or sound signals, for example by telephone.
Ved større mæreinnstallasjoner er det neppe påkrevet at hele noten har masker med innspunnet ledninger. En kan her tenke seg at den nedre del av noten, under 3 - 4m, kan best av vanlig tråd. In the case of larger measuring installations, it is hardly required that the entire groove has meshes with spun-in cables. One can imagine here that the lower part of the groove, below 3 - 4m, would do best with ordinary thread.
For at oppfinnelsens nyhetsstilling bedre skal komme til uttrykk, vil den i det etterfølgende bli nærmere forklart i forbindelse med vedlagte tegning hvor fig. 1 viser, sett fra siden, en skje-matisk utførelse av selve noten eller mæren hvor det går frem hvordan en tenker seg at de strømførende ledninger, som maskene består av, blir samlet i en vertikal pølse og ført opp til mærens plattform. Fig. 2 viser, sett fra siden, et utsnitt av noten hvor de strømførende ledninger fra annen hver maskeomfar samles i den vertikale pølse. In order for the novelty of the invention to be better expressed, it will subsequently be explained in more detail in connection with the attached drawing where fig. 1 shows, seen from the side, a diagrammatic execution of the groove or the mær itself, where one imagines that the current-carrying wires, of which the meshes are made up, are collected in a vertical sausage and led up to the mær's platform. Fig. 2 shows, seen from the side, a section of the groove where the current-carrying wires from every other mesh layer are gathered in the vertical sausage.
I figurene betegner A selve maskene i noten som i sine tråd-kjerner har innspunnet isolerte strømførende ledninger B. S betegner den vertikale ledningspølsen som samler de innspunne ledningene og fører disse til overflaten for tilkobling til strømkilde i land. D betegner elektroder som nedsenket og plas-sert rundt selve mæren E skal kunne fange opp signaler så snart det blir maskebrudd F. G betegner mærens plattform og H betegner flottører mens I betegner mærens rekkverk. In the figures, A denotes the actual meshes in the net which have spun in their cores insulated current-carrying wires B. S denotes the vertical wire sausage that collects the spun-in wires and leads them to the surface for connection to a power source on land. D denotes electrodes that are submerged and placed around the mare itself E must be able to pick up signals as soon as there is a mesh break F. G denotes the mare's platform and H denotes floats while I denotes the mare's railing.
