Abstract

Apparatus which preferably is usable for fish breeding by means of string bags and which is intended to pump up water of a watercourse from a low level to a higher level, at which the string bag intended for fish breeding is positioned, preferably to a level just below the water-line. The apparatus is characterized by the combination of the following features: the apparatus comprises an electrically driven motor (1), which is stationarily arranged above the water-line (4) and which is intended via an essentially vertical shaft (2), journalled freely from oil, to drive a device (3), which is positioned below the water-line (4) at a relatively large distance from this one for pumping up water; the device (3) is intended to be positioned at a lower part of an essentially vertically extending pipe (7) which is open at both of its ends, and through which the water, pumped up, is intended to stream; the pipe (7) is designed in that way at its upper end that the water stream through the mentioned pipe end can be controlled so that it is directed towards the string bag intended for fish-breeding.

Description

15 20 25 502 716 2 propelleraxeln 2 och är roterbart anordnad i undre delen av ett väsenligen vertikalt sig sträckande rör 7, genom vilket det uppfordrade vattnet är avsett att strömma. Därvid är propelleraxeln 2 av miljöskäl oljefritt lagrad i en övre 8 och en undre 9 bussning. Den undre bussningen 9 är anordnad inne i röret 7, medan den övre bussningen 8 är anordnad utanför röret 7. 502 502 716 2 propeller shaft 2 and is rotatably arranged in the lower part of a substantially vertically extending tube 7, through which the requested water is intended to flow. In this case, the propeller shaft 2 is oil-free mounted in an upper 8 and a lower 9 bushing for environmental reasons. The lower bushing 9 is arranged inside the tube 7, while the upper bushing 8 is arranged outside the tube 7.

Den övre delen av röret 7 uppvisar en rörböj 10, som är så anordnad att den är riktad mot en för fiskodling avsedd kasse 11, vilken är placerad pâ sidan om den uppfmnings- enliga anordningen. Propelleraxeln 2 genomgår sålunda rörböjen 10 och enligt denna ut- föringsform sker denna genomgång strax under den övre bussningen 8 för propelleraxeln 2.The upper part of the pipe 7 has a pipe bend 10, which is arranged so as to be directed towards a box 11 intended for cushioning, which is placed on the side of the device according to the invention. The propeller shaft 2 thus undergoes the pipe bend 10 and according to this embodiment this passage takes place just below the upper bushing 8 for the propeller shaft 2.

I den övre, yttre delen av rörböjen 10 är enligt uppfinningen ett spjäll 12 anordnat, som fimgerar som en övre skärrn för vattenströmmen genom rörböjen 10. Därvid är spjället 12 i sin nedre del ledat förbundet med rörböjen 10 och är avsett att regleras med hjälp av en på staget 5 anordnad stång 13 i en öppnande eller tillslutande riktning. Stången 13 är vid sin undre ände ledat förbunden med spjällets 12 övre del och är glidbart anordnad i en på staget 5 anordnad bussning 14. Med hjälp av spjället 12 kan vattenströmmen som pumpas ut genom rörböjen 10 riktas mot den för fiskodling avsedda kassen 11 på önskvärt sätt.In the upper, outer part of the pipe bend 10 according to the invention a damper 12 is arranged, which acts as an upper channel for the water flow through the pipe bend 10. In this case the damper 12 is in its lower part articulated connected to the pipe bend 10 and is intended to be regulated by means of a rod 13 arranged on the strut 5 in an opening or closing direction. The rod 13 is hingedly connected at its lower end to the upper part of the damper 12 and is slidably arranged in a bushing 14 arranged on the strut 5. By means of the damper 12 the water flow pumped out through the pipe bend 10 can be directed towards the box 11 intended for grouting as desired way.

Den nya anordningen medför att vattnet pumpas upp genom röret 7 och ut genom rörböjen 10 mot kassen ll. Genom den sugverkan som propellern 3 åstadkommer, uppstår en effektiv cirkulation av vatten genom kassen 11. Den uppfinningsenliga anordningen kan sålunda betecknas som strömbildare.The new device causes the water to be pumped up through the pipe 7 and out through the pipe bend 10 towards the box 11. Due to the suction effect produced by the propeller 3, an efficient circulation of water occurs through the box 11. The device according to the invention can thus be described as a current generator.

Under vissa omständigheter kan det vara nödvändigt att uppfordra vatten från en lägre nivå än den normala. Detta kan exempelvis vara fallet under hårda vintrar, då man behöver relativt sett varmare vatten för att hålla den för flskodling avsedda kassen isfri. I sådana fall kan enligt uppfinningen det befintliga röret 7 nedtill förlängas med ett förläng- ningsrör 15 som pà ett enkelt sätt kan skjutas utanpå det övre röret 7.In some circumstances, it may be necessary to encourage water from a lower level than normal. This may be the case, for example, during harsh winters, when relatively warm water is needed to keep the bag intended for cultivation ice-free. In such cases, according to the invention, the existing tube 7 at the bottom can be extended with an extension tube 15 which can be slid in a simple manner on the outside of the upper tube 7.

Uppfinningen är naturligtvis ej begränsad till den visade och angivna utföringsforrnen utan kan modifieras inom ramen för efterföljande patentkrav.The invention is of course not limited to the embodiments shown and stated but can be modified within the scope of the appended claims.
