Description
Foreliggende oppfinnelse vedrører en fremgangsmåte The present invention relates to a method
for oppløftning av <y>andrefisk. for the raising of <y>other fish.
Bygging av kraftverk i elver medfører som kjent ofte den ulempe at bestanden av vandrefisk utryddes. For å opprett-holde fiskebestanden er det utviklet et flertall forskjellige såkalte fisketrapper/ langs hvilke fiskene stiger opp mot strøm-men av egen fri vilje. En annen mulighet er å anvende såkalte fiskehelser ved hjelp av hvilke fiskene transporteres i tørr-lagte kurver eller vannfylte beholdere oppad i elvene. As is well known, the construction of power plants in rivers often entails the disadvantage that the population of migratory fish is exterminated. In order to maintain the fish population, a number of different so-called fish ladders have been developed/ along which the fish rise against the current - but of their own free will. Another possibility is to use so-called fish health systems, with the help of which the fish are transported in dry baskets or water-filled containers up the rivers.
For å unnvike de ulemper som forekommer i forbindelse med de tidligere kjente fremgangsmåter og anlegg samt for å opp-nå de mål som fremgår lengre fremme i beskrivelsen, er fremgangsmåten ifølge oppfinnelsen hovedsakelig karakterisert ved at vannet og fiskene i ett i et nedre vannbasseng beliggende lokkebasseng eller et til dette tilsluttet mindre oppsamlingsbasseng, som periodevis kan lukkes vann- og/eller lufttett, tvinges opp i et øvre vannbasseng, eller opp i sorteringsbassenger, gjennom en rørledning ved hjelp av en pumpe, som ikke skader fiskene, eller trykkluft. In order to avoid the disadvantages that occur in connection with the previously known methods and facilities, as well as to achieve the goals that appear further on in the description, the method according to the invention is mainly characterized by the fact that the water and the fish in a bait basin located in a lower water basin or a smaller collection basin connected to this, which can be periodically closed watertight and/or airtight, forced into an upper water basin, or into sorting basins, through a pipeline using a pump, which does not harm the fish, or compressed air.
Den gjennom en rørledning utførte tvangsforflytting ifølge oppfinnelsen, har i sammenlikning med de ovenfor angitte fremgangsmåter bl.a. følgende fordeler: lokkebassenget kan plasseres på det best mulige sted i det nedre vannbasseng, hvorved fremgangsmåtens effektivitet er bedre enn de ovenfor nevnte fremgangsmåters effektivitet, byggeomkostningene for et anlegg for gjennomføring av fremgangsmåten ifølge oppfinnelsen antas å være betydelig lavere enn for en fisketrapp med samme nytteverdi, The forced displacement according to the invention carried out through a pipeline has, in comparison with the above-mentioned methods, i.a. the following advantages: the bait basin can be placed in the best possible place in the lower water basin, whereby the efficiency of the method is better than the efficiency of the above-mentioned methods, the construction costs for a facility for carrying out the method according to the invention are assumed to be significantly lower than for a fish ladder with the same useful value ,
anlegget kan plasseres slik at det ikke forstyrrer landskapet, med fremgangsmåten ifølge oppfinnelsen går mindre vannkraft- the plant can be placed so that it does not disturb the landscape, with the method according to the invention less hydropower
energi til spille enn ved fisketrapper med fritt strømmende vann, - fremgangsmåten er ikke like utsatt for mekaniske feil og klimaforstyrrelser som f.eks. de tidligere kjente fiskehelser. wasted energy than with fish ladders with free-flowing water, - the method is not as susceptible to mechanical errors and climate disturbances as, for example, the previously known fish health.
Et anlegg for gjennomføring av fremgangsmåten ifølge oppfinnelsen omfatter ett eller flere lokkebassenger og eventuelt dessuten til disse tilsluttede mindre oppsamlingsbassenger, hvilke periodevis kan lukkes vann- eller lufttett enten automat-isk eller manuelt. Herved kan altså et bestemt og begrenset vann-volum samt fisker tvinges opp i et øvre vannbasseng eller opp i sorteringsbassenger gjennom en rørledning ved hjelp av en pumpe, som ikke skader fiskene, eller trykkluft. A facility for carrying out the method according to the invention comprises one or more decoy basins and possibly also connected to these smaller collection basins, which can periodically be closed watertight or airtight either automatically or manually. In this way, a specific and limited volume of water and fish can be forced into an upper water basin or into sorting basins through a pipeline using a pump, which does not harm the fish, or compressed air.
Oppfinnelsen skal beskrives detaljert i det etterfølg-ende med henvisning til tre i figurene på den etterfølgende teg-ning viste utførelsesformen. Det er dog ikke meningen å begrense oppfinnelsen i detalj til disse utførelsesformer. Fig, 1 viser et oppriss av en første utførelsesform, The invention shall be described in detail in the following with reference to three figures in the subsequent drawing shown in the embodiment. However, it is not intended to limit the invention in detail to these embodiments. Fig, 1 shows an elevation of a first embodiment,
Fig. 2 viser et sideriss av samme utførelsesform, Fig. 2 shows a side view of the same embodiment,
Fig, 3 viser et oppriss av en andre utførelsesform, Fig. 4 viser et oppriss av en tredje utførelsesform. Fig, 3 shows an elevation of a second embodiment, Fig. 4 shows an elevation of a third embodiment.
Den første utførelsesforms funksjonsprinsip er følgende: The first embodiment's functional principle is as follows:
Når vandrefiskene svømmer mot strømmen kommer de inn When the migratory fish swim against the current, they enter
i et lokkebasseng 3 fra et nedre vannbasseng 1. Et ledenett 2 hindrer fiskene i å svømme forbi lokkebassenget og et stoppnett i den øyre ende av lokkebassenget hindrer fiskene i å svømme ut a<y> dette. Den nødvendige lokkestrøm gjennom bassenget (ca. 4 m pr, sekund), oppnås ved hjelp a<y> en naturlig eller ved hjelp av en pumpe tilveiebragt strømning. Ved denne utførelsesform effekti-yeres strømmen ved hjelp av en vannejektor 8. Lokkebassenget er forsynt med stengeluker 4 som stenges med bestemte mellomrom og samtidig styres vannet fra en vannpumpe 10 via en trevegsventil 9 til en ejektor 6 i et stigerør 7. Ejektorens 6 effekt skal være tilstrekkelig stor til å overvinne det hydrostatiske trykket i det til et øvre vannbasseng 11 eller til sorteringsbassenger 12 ledende, med en tilbakeslagsventil forsynt stigerør 7, og for å tømme lokkebassenget 3. Vannpumpen 10 får sitt vann enten fra det øvre vannbasseng 11 hvorved relativt liten pumpeeffekt kreves, eller fra det nedre vannbasseng 1. På dette vis kan altså fiskene transporteres forbi et kraftverk 13 eller hvilket in a bait pool 3 from a lower water pool 1. A guide net 2 prevents the fish from swimming past the bait pool and a stop net at the far end of the bait pool prevents the fish from swimming out of this. The necessary lure current through the pool (approx. 4 m per second) is achieved by means of a natural or by means of a pump provided flow. In this embodiment, the flow is made more efficient by means of a water ejector 8. The bait basin is provided with shutters 4 which are closed at specific intervals and at the same time the water is controlled from a water pump 10 via a three-way valve 9 to an ejector 6 in a riser 7. The effect of the ejector 6 must be sufficiently large to overcome the hydrostatic pressure in it to an upper water basin 11 or to sorting basins 12 leading, with a non-return valve provided riser 7, and to empty the decoy basin 3. The water pump 10 receives its water either from the upper water basin 11 whereby relatively small pump power is required, or from the lower water basin 1. In this way, the fish can therefore be transported past a power plant 13 or which
som helst annet oppstigningshinder. any other obstacle to ascent.
Funksjonsprinsippet for den andre utførelsesform er hovedsakelig identisk med funksjonsprinsippet for den første ut-førelsesf orm. På et punkt skiller dog disse to funksjonsprinsipper seg fra hverandre. Ved den andre utførelsesform kan nemlig lokkebassenget 3 lukkes ved hjelp av lukene 4 slik at det dannes et lufttett rom som tåler et tilsvarende oppdemningshøyden svarende trykk. Etter at lukene er stengt, pumpes luft inn i bassengrommet ved hjelp av en kompressor 14. Helt til vannet og fiskene i lokkebassenget er presset gjennom stigerøret 7 opp i det øvre vannbasseng 11 eller opp i sorteringsbassenget 12, hvor fiskene har passert kraftverkdammen 13 eller et annet oppstigningshinder. Stigerørets innløpsåpning er i fig. 3 merket med henvisnings-tallet 5. Heretter åpnes lokkedammens luker 14. Dette anlegg arbeider periodevis likeledes som det allerede ovenfor beskrevne anlegg. The functional principle for the second embodiment is essentially identical to the functional principle for the first embodiment. At one point, however, these two functional principles differ from each other. In the second embodiment, the decoy pool 3 can be closed by means of the hatches 4 so that an airtight space is formed which can withstand a corresponding pressure corresponding to the impoundment height. After the hatches are closed, air is pumped into the pool space using a compressor 14. Until the water and the fish in the bait pool are pushed through the riser 7 into the upper water pool 11 or into the sorting pool 12, where the fish have passed the power plant pond 13 or a other ascent obstacle. The inlet opening of the riser is in fig. 3 marked with the reference number 5. The hatches of the bait dam 14 are then opened. This facility works periodically in the same way as the facility already described above.
Den i fig. 4 viste tredje utførelsesforms funksjons-prinsipp følger stort sett den andre utførelsesforms funksjons-prinsipp. Ved den tredje utførelsesform tilveiebringes dog den nødvendige trykkluft ved hjelp av vannpumpen 10 og en mellombeholder 15. Mellombeholderens 15 volum skal være minst like stort som volumet ved normalt trykk for den luftmengde som ved et til oppdemningshøyden svarende trykk, rommes i lokkebassengrommet. Etterat lukene 4 har lukket bassengrommet lufttett, føres vann The one in fig. The functional principle of the third embodiment shown in 4 largely follows the functional principle of the second embodiment. In the third embodiment, however, the necessary compressed air is provided with the help of the water pump 10 and an intermediate container 15. The volume of the intermediate container 15 must be at least as large as the volume at normal pressure for the amount of air that, at a pressure corresponding to the dam height, is accommodated in the lure pool space. After the hatches 4 have closed the pool room airtight, water is introduced
fra pumpen 10 via trevegsventilen 9 inn i den luftfylte mellombeholder 15. Beholderen 15 er forsynt med en lufteventil 17 og en vannforbindelsesledning 18 til lokkebassenget. Disse er lukket i det trinn da vann pumpes inn i beholderen. Mens mellombeholderen 15 fylles med vann, tømmes lokkebassenget 3 gjennom stigerøret 7 ved innvirkning av den trykkluft som strømmer inn i bassengrommet gjennom en trykkluftforbindelsesledning 16 mellom mellombeholderen og lokkebassenget. Når lokkebassenget er helt tømt åpnes stengelukene 4 og vannforbindelsesledningen mellom mellombeholderen og lokkebassenget gjennom hvilken det vann som er kommet inn i mellombeholderen 15 strømmer ned i lokkebassenget. Endog dette anlegg arbeider periodevis. from the pump 10 via the three-way valve 9 into the air-filled intermediate container 15. The container 15 is provided with an air valve 17 and a water connection line 18 to the bait basin. These are closed at the stage when water is pumped into the container. While the intermediate container 15 is filled with water, the bait pool 3 is emptied through the riser 7 by the influence of the compressed air that flows into the pool space through a compressed air connection line 16 between the intermediate container and the bait pool. When the decoy basin is completely emptied, the shutters 4 and the water connection line between the intermediate container and the decoy basin are opened, through which the water that has entered the intermediate container 15 flows down into the decoy basin. Even this facility works periodically.
Oppfinnelsen er ikke begrenset til de ovenfor beskrevne utførelsesformer, idet oppfinnelsens detaljer kan variere innen rammen for den i de etterfølgende patentkrav definerte oppfinnel-ses tanke. The invention is not limited to the embodiments described above, as the details of the invention may vary within the framework of the idea of the invention defined in the subsequent patent claims.
