Description

DK 155903BDK 155903B

Opfindelsen angår et fiskeopdrætningsapparat af den i krav l's indledning angivne art.The invention relates to a fish farming apparatus of the type specified in the preamble of claim 1.

Det er kendt at anvende opbevaringsbure til levende 5 fisk, hvor burene enten holdes flydende ved hjælp af flydelegemer, eller fastholdes på deres position ved fortøjning til f.eks. pæle, der er rammet ned i havbunden. Disse bure anvendes i hovedsagen som fælder eller net (ruser), samt til opbevaring af indfangede fisk. I 10 sådanne fiskebure skal fiskene kun holdes i live i kort tid inden de ender som konsumfisk og burene er derfor anbragt i en fast højde enten i forhold til fortøjningspælene eller i forhold til havoverfladen.It is known to use storage cages for live fish, where the cages are either kept afloat by means of floating bodies, or held at their position by mooring to e.g. piles hit into the seabed. These cages are mainly used as traps or nets (ruses), as well as for storing captured fish. In 10 such fish cages, the fish must only be kept alive for a short time before they end up as consumer fish and the cages are therefore placed at a fixed height either in relation to the mooring poles or in relation to the sea surface.

15 Målet med opfindelsen er at angive et fiskeopdrætnings-apparat, der muliggør langtidsopbevaring af levende fisk, og som er enkelt og billigt at fremstille og let at betjene, samt er tilstrækkeligt robust til at kunne anvendes i havvand.The object of the invention is to provide a fish farming apparatus which enables long-term storage of live fish, which is simple and inexpensive to manufacture and easy to operate, and is sufficiently robust to be able to be used in seawater.

Dette formål opnås ved, at fiskeopdrætningsapparatet er udformet som angivet i krav l's kendetegnende del. Denne konstruktion giver mulighed for at variere fiskenes temperaturmiljø inden for visse grænser, idet vandtempera-25 turen i de øvre vandlag under normale forhold aftager noget fra overfladen og nedefter. Temperaturgradienten kan f.eks. være af størrelsesordenen l°C/m. Ændring af burets højdestilling i forhold til vandoverfladen vil naturligvis også influere på andre forhold af betydning 30 for fiskene, f.eks. det rumfang vand, der er til rådighed for fiskene, og virkningen af bølgeskvulp.This object is achieved in that the fish farming apparatus is designed as stated in the characterizing part of claim 1. This construction makes it possible to vary the temperature environment of the fish within certain limits, as the water temperature in the upper water layers under normal conditions decreases somewhat from the surface and downwards. The temperature gradient can e.g. be of the order of 1 ° C / m. Changing the height of the cage in relation to the water surface will of course also influence other conditions of importance 30 for the fish, e.g. the volume of water available to the fish and the effect of wave action.

Med passende intervaller skal buret drejes, for at plantevækster, der afsættes på den neddykkede del af buret 35 og vil efterhånden kunne tilstoppe dette mere eller mindre, og løftes op i luften, hvor de ret hurtigt tørrer 2At appropriate intervals, the cage must be rotated so that plant growths deposited on the submerged part of the cage 35 and will eventually be able to clog it more or less, and lift up into the air, where they dry fairly quickly 2

ind og derefter let kan fjernes.in and then can be easily removed.

Meget enkle og robuste udførelser af de midler, der muliggør lodret indstilling af buret, er angivet i krav 2 5 og 3.Very simple and robust embodiments of the means enabling the vertical adjustment of the cage are specified in claims 2 5 and 3.

Opfindelsen skal forklares nærmere i det følgende under henvisning til tegningen, hvor 10 fig. 1 viser en udførelsesform for fiskeopdrætningsappa- ratet ifølge opfindelsen set fra oven, fig. 2 en del af samme set fra siden, og 15 fig. 3 det ene bæreaggregat set fra den mod buret vendende side.The invention will be explained in more detail in the following with reference to the drawing, in which fig. Fig. 1 shows a top view of an embodiment of the fish farming apparatus according to the invention; 2 a part of the same seen from the side, and fig. 3 one support unit seen from the side facing the cage.

Det på tegningen viste fiskeopdrætningsapparat bæres af et flydelegeme-arrangement, der som helhed er betegnet 20 med 10, og som består af et antal i hovedsagen kasseformede flydelegemer 11, der er fast forbundet med hinanden ved hjælp af sammenboltede øvre og nedre stænger 12. Flydelegeme-arrangementet er tilnærmelsesvis ellipseformet.The fish farming apparatus shown in the drawing is carried by a floating body arrangement, designated as a whole 20 by 10, and which consists of a number of substantially box-shaped floating bodies 11, which are fixedly connected to each other by means of bolted upper and lower rods 12. Floating body the arrangement is approximately elliptical.

25 På de to flydelegemer 11, der ligger diametralt over for hinanden på ellipsens storakse, er der anbragt et bæreaggregat, der som helhed er betegnet med 30, og som understøtter hver sin ende af et bur, der som helhed er 30 betegnet med 20.Arranged on the two floating bodies 11, which lie diametrically opposite each other on the major axis of the ellipse, is a support unit, which as a whole is denoted by 30, and which each supports its own end of a cage, which as a whole is denoted by 20.

Buret 20 har tilnærmelsesvis form som en omdrejningsellipsoide og består af et antal plastrør 21, der er bøjet i den ønskede form svarende til burets kontur, og som 35 ved enderne er forbundet med hinanden i stjerneform på vilkårligt passende, ikke nærmere vist måde, f.eks. ved 3The cage 20 has approximately the shape of a rotating ellipsoid and consists of a number of plastic tubes 21 bent in the desired shape corresponding to the contour of the cage, and which at the ends are connected to each other in star shape in any suitable, not shown manner, f. ex. at 3

hjælp af en navplade med påsvejsede rørstykker til optagelse af hver sin plastrørende. Plastrørene 21 er yderlige forbundet med hinanden ved hjælp af et antal tværstivere 22, der også kan bestå af plast, og som i planer 5 vinkelret på burets længdeakse kan danne enten cirkler eller polygoner. På indersiden af det stativ 21, 22, der danner buret, er der udspændt et ikke vist net, og buret er yderligere på kendt, ikke nærmere vist måde udformet med en passende åbning, som kan lukkes af en lem, hvor-10 igennem der kan indføres og udtages fisk.by means of a hub plate with welded-on pipe pieces for receiving their respective plastic pipes. The plastic tubes 21 are further connected to each other by means of a number of cross braces 22, which may also consist of plastic and which in planes 5 perpendicular to the longitudinal axis of the cage can form either circles or polygons. On the inside of the stand 21, 22 forming the cage, a net (not shown) is stretched, and the cage is further formed in a known, not shown in more detail, with a suitable opening which can be closed by a limb through which fish can be imported and taken out.

På hver ende og koaksialt med buret er der anbragt en akseltap 23, ved hjælp af hvilke buret er drejeligt ophængt i bæreaggregaterne. På denne inderste del af den 15 ene eller begge akseltappe 23 er fastgjort et nav 24, der bærer et antal i stjerneform anbragte, radiale rørstykker 25, hvis formål vil fremgå af det følgende.At each end and coaxially with the cage, a shaft pin 23 is arranged, by means of which the cage is rotatably suspended in the support units. Attached to this inner part of the one or both shaft pins 23 is a hub 24 which carries a number of radial pipe pieces 25 arranged in a star shape, the purpose of which will appear from the following.

Hvert bæreaggregat 30 består i hovedsagen af to paral-20 leile, lodrette stænger eller rør 31, der er forbundet med hinanden forneden ved hjælp af en tværstang 32. I nogen afstand fra de øvre ender er hver stang 31 påsvej-set to knægte 33, som strækker sig udad og er fastsvej-set til henholdsvis oversiden og undersiden af det til-25 stødende flydelegeme 11. Et par skråstivere 34 strækker sig mellem den nedre ende af hver stang 31 og yderkanten af flydelegemet. På indersiden af hver stang 31 er der i nærheden af dens øvre ende påsvejset en vinkelplade 35, som danner en opadtil åben krog.Each support assembly 30 consists essentially of two parallel, vertical rods or tubes 31 connected to each other at the bottom by means of a cross bar 32. At some distance from the upper ends, each rod 31 is welded to two brackets 33, which extends outwardly and is welded to the upper side and the underside, respectively, of the adjacent floating body 11. A pair of inclined struts 34 extend between the lower end of each rod 31 and the outer edge of the floating body. On the inside of each rod 31, an angular plate 35 is welded in the vicinity of its upper end, which forms an upwardly open hook.

Hver af burets lejetappe 23 går ind i en lejebøsning 36, som er fastgjort til den nedre ende af en i hovedsagen lodret bærestang 37, som har to i nogen indbyrdes afstand beliggende traverser 38, hvoraf den ene findes på 35 den øverste ende af bærestangen. På tegningen er den øverste travers vist anbragt i krogene 35 på den øvreEach of the bearing pins 23 of the cage enters a bearing bush 36 which is attached to the lower end of a substantially vertical support rod 37 which has two spaced apart traverses 38, one of which is located at 35 the upper end of the support rod. In the drawing, the upper traverse is shown arranged in the hooks 35 on the upper

4 ende af stængerne 31. I denne stilling er buret 20 helt neddykket i vandet. Det er imidlertid muligt at hæve buret op i en sådan stilling, at burets længdeakse er beliggende et lille stykke under vandoverfladen ved, at 5 bærestangens nederste travers 38 løftes op og anbringes i krogene 35. I denne stilling befinder næsten halvdelen af buret 20 sig således over vandet.4 end of the rods 31. In this position the cage 20 is completely submerged in the water. However, it is possible to raise the cage up in such a position that the longitudinal axis of the cage is located a short distance below the water surface by lifting the lower cross member 38 of the support rod and placing it in the hooks 35. In this position almost half of the cage 20 is thus over the water.

På bærestangen 37's inderside er fastgjort to lejebøs-10 ninger 39 for en lodret forskydelig låsestang 41, der foroven har et håndtag 42, og hvis nederste ende kan bringes til at gribe ind i et vilkårligt valg af rørstykkerne 25 på navet 24, hvorved buret fastlåses mod drejning. Når buret ønskes drejet, f.eks. med henblik på 15 udtagning af fisk eller rensning for plantevækster, løftes låsestangen 41 ud af indgreb med rørstykket, hvorefter buret frit kan drejes ind i den ønskede nye stilling, hvori den fastlåses ved, at låsestangen skydes ned i det nu opadvendende rørstykke 25.Attached to the inside of the support rod 37 are two bearing bushings 39 for a vertically displaceable locking rod 41 having a handle 42 at the top and the lower end of which can be caused to engage in any choice of the pipe pieces 25 on the hub 24, thereby locking the cage against rotation. When the cage is to be turned, e.g. for the purpose of removing fish or cleaning for plant growth, the locking rod 41 is lifted out of engagement with the pipe section, after which the cage can be freely rotated into the desired new position, in which it is locked by sliding the locking rod into the now upwardly facing pipe section 25.

Indhøstningen af fisk fra buret 20 kan på i for sig kendt måde lettes ved, at der i buret udspændes et ikke vist net, som i udspændt tilstand forløber langs et radialplan i buret. Ved drejning af buret kan alle fiskene 25 da bringes til at ligge på dette net i et snævert, kileformet rum lige under vandoverfladen. Når nettet ikke er i brug, kan det være foldet sammen og fastbundet til et af plastrørene 21.The harvesting of fish from the cage 20 can be facilitated in a manner known per se by stretching a net (not shown) in the cage, which in the stretched state extends along a radial plane in the cage. By rotating the cage, all the fish 25 can then be brought to rest on this net in a narrow, wedge-shaped space just below the water surface. When not in use, the net may be folded and tied to one of the plastic tubes 21.

30 De konstruktive enkeltheder ved fiskeopdrætningsappara-tet kan være udformet på andre måder end vist på tegningen og beskrevet ovenfor. F.eks. kan rørstykkerne 25 på navet 24 på burets akseltappe erstattes med tappe, som en rørfatning på den nedre ende af låsestangen 41, 35 kan bringes til at gribe om. I stedet for at understøttes af et flydelegeme-arrangement 10 kan bæreaggregater-The constructive details of the fish farming apparatus may be designed in other ways than shown in the drawing and described above. For example. For example, the pipe pieces 25 on the hub 24 on the shaft journal of the cage can be replaced with pins which a pipe socket on the lower end of the locking rod 41, 35 can be made to grip. Instead of being supported by a floating body arrangement 10, support assemblies may

5 ne 30 eventuelt være indrettet til at fastgøres på bundpæl, f.eks. ved, at der på ydersiden af de lodrette stænger 31 er fastgjort spændbøjler, der kan fastspændes omkring sådanne nedrammede pæle. Der kan også være flere 5 end to traverser 38 på bærestangen 37, så at buret kan fastholdes i flere forskellige højdestillinger.5 ne 30 may be arranged to be attached to the bottom pile, e.g. in that clamping brackets are attached to the outside of the vertical rods 31 which can be clamped around such framed piles. There may also be more than two traverses 38 on the support rod 37 so that the cage can be held in several different height positions.

Ved større bure kan det være nødvendigt eller ønskeligt at udstyre bæreaggregaterne med mekaniske hjælpemidler 10 til løftning og sænkning af buret, f.eks. i form af taljer.In the case of larger cages, it may be necessary or desirable to equip the support units with mechanical aids 10 for lifting and lowering the cage, e.g. in the form of hoists.
