i DK 167641 B1 AKTIVT LEDESYSTEM FOR USTRESSET GUIDING AF LEVENDE FISK I VAND.in DK 167641 B1 ACTIVE MANAGEMENT SYSTEM FOR USTRESSED GUIDING OF LIVING FISH IN WATER.
Opfindelsen angår et aktivt styre og ledesystem for 5 vådsortering og ustresset guiding af levende fisk i vand.The invention relates to an active control and management system for wet sorting and unstressed guiding of live fish in water.
Hidtil har man kun kendt passive sorteringssystemer af levende fisk, hvilket vil sige at man ofte manuelt har tvunget eller ført fisken nedover eller hen til og ofte 10 i store sammenhængende kvanta til et sorteringsaggregatet, hvor de da ofte ved deres vægt som på grund af stress og angst har forsøgt ved egen kraft at bevæge og skynde sig bort .So far, only passive sorting systems of living fish have been known, which means that they have often manually forced or brought the fish down or to and often 10 in large continuous quantities to a sorting unit, where they are often at their weight as a result of stress. and anxiety has tried by its own power to move and hurry away.
15 Der er kendt systemer, hvor man har ristearrangementer med forskellige mellemrum. Man hælder ved denne almindelig metode de indfangne fisk ned oven på risten, hvorved de største som de mindste kan sorteres rimeligt. Idet dog nogle af de små fisk også vil kunne gå ned i mellem de 20 store ristelysninger.15 There are known systems in which there are shaking arrangements at various intervals. By this ordinary method, the trapped fish are poured down on the grid, whereby the largest as the smallest can be reasonably sorted. However, since some of the small fish will also be able to go down in between the 20 large shake lights.
Ved dette system er der meget store ulemper forbundet, idet man for det første skal indfange fiske eller jage den hen til et ristesystem, hvorved fisken får stress. Yderligere har man også været nødt til, at sulte fisken 25 før man sorterede dem, hvilket også har givet fisken yderlige stress. Og ofte har en ristesortering medført at adskillige fisk har hængt fast i deres gæller, eller har fået brækket rykken og ødelagt finner på grund af den hårdhændede behandling.This system has many major drawbacks, in the first place that you have to catch fish or chase it to a shaking system, whereby the fish get stress. Furthermore, they also had to starve the fish 25 before sorting them, which also gave the fish additional stress. And often, a toast sorting has resulted in several fish being trapped in their gills, or having their jerky broken and broken fins due to the harsh treatment.
30 Det har herfor taget lang tid før fiskene igen begyndte at tage normal føde til sig, og kødet har også smagsmæssigt taget skade at stress-faktorerne.30 It has therefore taken a long time for the fish to start eating normal food again, and the meat has also tastefully damaged the stress factors.
Eksempelvis er der gældende for pattedyr såsom svin, at deres kød ved stress symptomer, bliver meget vandige og 35 lyst, og smagen ændrer sig til det dårligere. Et lignende fænomen er gældende for eksempelvis laks og andre fisk.For example, for mammals such as pigs, their meat under stress symptoms becomes very watery and bright, and the taste changes for the worse. A similar phenomenon applies to salmon and other fish, for example.

Formålet med opfindelsen er at opnå en aktiv vådsortering af den enkelte fisk uden at den bliver jaget, berørt og derfor meget stresset og forvirret, og hvor den i slutfasen roligt er blevet ledt til sit eget specifikke 5 seperationsområde.The object of the invention is to achieve an active wet sorting of the individual fish without being hunted, affected and therefore very stressed and confused, and where in the final phase it has been quietly led to its own specific area of separation.
Dette opnås ifølge opfindelsen ved, at hver enkelt fisk først bringes til at svømme gennem et målecellearrangement for direkte styret via de netop indhentede data 10 her efterfølgende, at blive ledet i svømmende tilstand til det specifikke område relateret til henholdsvis vægt som volumen af den aktuelle fisk.This is achieved according to the invention in that each fish is first caused to swim through a measuring cell arrangement for directly controlled via the data just obtained hereinafter, to be guided in a swimming state to the specific area related to weight and volume, respectively, of the actual fish. .
Det aktive ledesystem er placeret således efter målecel-15 len, at der umiddelbart for fisken ikke er nogen hurtige og rimelige synlige forstyrrende bevægende dele her.The active guidance system is positioned according to the measuring cell so that there are no fast and reasonably visible disturbing moving parts immediately before the fish.
Dette findes først i en vis tilpasset afstand fra udgangen i målecellen til det aktuelle separations åbnings område, hvor ledemekanismens bevægelse i hastig-20 hed og retningsbevægelse yderligerere tilpasset således, at den generelt svarer og harmonere til fiskens svømme-hastighed og bevægeretning, hvorfor ledesystemet ikke virker forstyrrende og stressende på den sorterende fisk.This is first found at some adapted distance from the output of the measuring cell to the opening separation area of the current separation, where the movement of the guiding mechanism in velocity and directional motion is further adapted so that it generally corresponds to and harmonizes with the swimming speed and direction of movement of the fish, why the guiding system does not seems disturbing and stressful on the sorting fish.
25 I en særlig udførselsform for ledemekanismen ifølge opfindelsen kan systemet bestå af især to med hinanden forbundne og forskydelige låger eller porte for adgangsåbninger til sorteringsområdeme, og lågerne kan ideelt være placeret i en vinkel på eksempelvis indbyrdes 30 omkring 90 grader, og med en vinkel i forhold til svømmeretningen for fisken som symmetriakselen for aggregatet på 45 grader, og at lågerne henholdsvis lukker og åbner for det specifikke seperationsområde, dog således at når den ene låge er åben er den anden lukket.In a particular embodiment of the guiding mechanism according to the invention, the system may consist in particular of two interconnected and sliding doors or gates for access openings to the sorting areas, and the doors can ideally be positioned at an angle of, for example, about 30 degrees, and at an angle of relative to the swim direction of the fish as the axis of symmetry of the aggregate at 45 degrees, and that the hatches respectively close and open for the specific separation area, however, so that when one hatch is open the other is closed.
I en anden særlig udførselsform for ledemekanismen ifølge 35 DK 167641 B1 3 opfindelsen kan ledesystemet bestå af en bevægelig gennemgangssluse der er fast hængslet ved målecellen, og bevægelig eller svingbar til den ene adgangsåbning og henholdsvis den anden adgangsåbning afhængig af den 5 aktuelle fundne vægt og størrelse for den aktuelle gennemsvømmende fisk.In another particular embodiment of the guiding mechanism according to the invention, the guiding system may consist of a movable passage lock fixedly hinged to the measuring cell and movable or pivotable to one access opening and the other access opening, respectively, depending on the weight and size found. for the current floating fish.
I en anden særlig udførselsform for ledemekanismen ifølge opfindelsen kan ledesystemet være udstyret med strøm-10 førende men isolerende ledere i sideretningen eller i begge sider for usynlig feltledning og føring af fisken til det aktuelle område.In another particular embodiment of the guiding mechanism according to the invention, the guiding system may be provided with current but insulating conductors in the lateral direction or on both sides for invisible field conduction and guiding the fish to the current area.
Fordelagtige modificerede udførsel s former for opfindelsen 15 fremgår yderligere af de uselvstændige krav 2-7.Advantageously modified embodiments of the invention 15 are further apparent from the dependent claims 2-7.
Opfindelsen forklares nærmere i det følgende under henvisning til tegningens figurer, hvor 20The invention will be explained in greater detail below with reference to the drawings in which: FIG
Fig.l viser et aktiv styre og ledesystem med målcelle,Fig. 1 shows an active control and control system with target cell,
Fig.2 viser et aktiv styre og ledesystem med 25 skråtstillede adgangsåbninger til seperationsområderne, ogFig. 2 shows an active control and management system with 25 inclined access openings for the separation areas, and
Fig.3 viser et aktiv styre og ledesystem med svingbar ledesektion for adgangsåbningerne til sepera- 30 tionsområderne.Fig. 3 shows an active control and guiding system with pivotal guide section for the access openings to the separation areas.
Fig.l viser et aktiv styre -og ledesystem med en målcelle (2), hvor den enkelte fisk (3) er ledt (6 og 5) 35 igennem. Eksempelvis vil det nærværende system (2, 5 og 6) være ideelt for runde bassiner, hvor fisken (3) ofte DK 167641 Bl 4 på grund af den cirkulære vandstrøm svømmer i ring, og da via et tragtformet netarrangement ideelt placeret ved bassinets yder periferi enkeltvis kan ledes til og gennem en målcelle (2) for automatisk registrering af volumen og 5 vægten.Fig. 1 shows an active steering and guiding system with a target cell (2) through which the individual fish (3) is guided (6 and 5) 35. For example, the present system (2, 5 and 6) would be ideal for round basins, where the fish (3) often swim in the ring due to the circular water flow, and then via a funnel-shaped net arrangement ideally located at the outer periphery of the basin. can be individually directed to and through a target cell (2) for automatic volume detection and weight.
Målcellens (2) data kan nu aktivere (1) adgangen til det specifikke seperationsområde (4 eller 4') for den aktuelle fisk (3), idet der som eksempelvis vist på fig.l kan åbnes (5) eller lukkes (5') en adgangsåbning (5 eller 10 5'). Dog således at adgangen til det modsatte område (4 som 4') lukkes, og således at lukke/åbne-bevægelsen (14) ikke bringer forstyrrende og stressende momenter i fiskens (3) aktuelle svømmemønster eller rytme.The target cell (2) data can now enable (1) access to the specific separation area (4 or 4 ') of the actual fish (3), as, for example, shown in FIG. 1, it can be opened (5) or closed (5'). an access opening (5 or 10 5 '). However, so that access to the opposite area (4 as 4 ') is closed and so that the closing / opening movement (14) does not bring disturbing and stressful moments in the current swimming pattern or rhythm of the fish (3).
Adgangen (61) til seperationsområdet (4 som 4') kan 15 ideelt være placeret 1-3 fiskelængder (7) fra udgangssiden på målcellen (2).The access (61) to the separation area (4 as 4 ') may ideally be located 1-3 fish lengths (7) from the exit side of the target cell (2).
Fig.2 viser et aktiv styre -og ledesystem (9 og 9' ) med skråtstillede (12) adgangsåbninger (5 og 51) til 20 seperationsområderne (4 som 4'), hvor åbningerne (5 og 5') kan aktiveres (14) eksempelvis via nogle forskydelige lemme eller porte (9 og 9'), som ideelt kan være forbundet sammen bevægelsesmæssigt via et centralt placeret rullearrangement (10) med wire til hver af portene 25 således, at når den ene åbner, at så lukker den anden i samme takt med samme hastighed.Fig. 2 shows an active control and guiding system (9 and 9 ') with inclined (12) access openings (5 and 51) to the 20 separation areas (4 as 4') where the openings (5 and 5 ') can be activated (14). for example via some slidable hinges or gates (9 and 9 ') which can ideally be connected together in movement via a centrally located roller arrangement (10) with wire to each of the ports 25 such that when one opens, the other closes in the same rate at the same speed.
Systemet (9, 9’ og 11) kan ideelt styres således, at lågerne ( 9 og 9') lukkes eller åbnes med ca. samme hastighed (8) som fisken (3) svømmer, og hastigheden (8) 30 hvormed fisken (3) især laksen (3') passere (8') igennem systemet (2, 5 og 5') kan ligge på omkring 1 sekund.The system (9, 9 'and 11) can ideally be controlled so that the doors (9 and 9') are closed or opened by approx. the same speed (8) as the fish (3) swims, and the speed (8) at which the fish (3) in particular the salmon (3 ') pass (8') through the system (2, 5 and 5 ') can be about 1 second .
En ideel vinkel (12) for synligheden af adgangsåbningen (5 og 5') for fisken (3) er, at lågerne (9 og 9') er placeret med en vinkel på 45 grader (12) i forhold til 35 midterlinien for systemet.An ideal angle (12) for the visibility of the access opening (5 and 5 ') for the fish (3) is that the lids (9 and 9') are located at an angle of 45 degrees (12) relative to the center line of the system.
Adgangsvejen (6 og 11) fra målecellens (2) udgang til DK 167641 B1 5 seperationsområdeporte (9 og 9') kan ideelt udføres konisk (11') med mindste diameter ved målcellen (2) til den største diameter ved hver sin ydre side af adgangsvejene (5 og 5').The access path (6 and 11) from the output of the measuring cell (2) to the separation area gates (9 and 9 ') can ideally be conical (11') with the smallest diameter at the target cell (2) to the largest diameter at each outer side of the the access roads (5 and 5 ').
