Opfindelsen angår et vandstråledrev til drift og styring af navnlig fartøjer med ringe dybgående, med en på en lodret aksel lejret propellerpumpe, som er drevet fra en i fartøjets skrog lejret motor via et 5 transmissionsaggregat, og som er anbragt inden i skibsskroget og umiddelbart over skibsbunden, hvorhos propellerpumpen er anbragt i en om propelleraksen svingbar bøjning.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a water jet drive for operating and controlling, in particular, low-draft vessels, with a propeller pump mounted on a vertical shaft driven from an engine mounted in the vessel's hull via a transmission assembly and disposed within the hull and immediately above the ship's bottom. , wherein the propeller pump is disposed in a bend pivotable about the propeller shaft.
Fra US-PS 3 098 464 kendes et vandstråledrev 10 af denne art, hvor drivaggregatets bøjning har en udløbsåbning, som er anbragt i samme plan som indløbsåbningen.From US-PS 3,098,464 a water jet drive 10 of this kind is known in which the bending of the drive unit has an outlet opening which is arranged in the same plane as the inlet opening.
En sådan anbringelse af udløbsåbningen indebærer imidlertid visse ulemper. For det første kræver 15 udformningen af bøjningen megen plads, og for det andet er dens udløb rettet skråt nedad, hvorfor der kun udnyttes en komponent af udgangsstrømningen til fartøjets drift, idet den anden komponent blot søger at løfte fartøjet.However, such placement of the outlet opening involves certain disadvantages. Firstly, the design of the bend requires a lot of space, and secondly, its outlet is directed downwardly, so that only one component of the output flow is used for the operation of the vessel, the other component merely seeking to lift the vessel.
20 Ifølge opfindelsen undgås disse ulemper ved, at et vandstråledrev af den i indledningen nævnte art er ejendommelig ved, at bøjningen er L-formet med en lodret indløbsarm, som ikke rager ned under skrogets bund, og en hovedsagelig vandret udløbsarm, hvis dyse-25 formede munding er rettet valgfrit umiddelbart ud af skibsskroget eller mod i skibsskroget anbragte, eksempelvis til siderne rettede kanaler eller en mod skibsbunden skrånende, eksempelvis fremadrettet kanal.According to the invention, these disadvantages are avoided in that a water jet drive of the kind mentioned in the preamble is characterized in that the bend is L-shaped with a vertical inlet arm which does not protrude below the bottom of the hull, and a substantially horizontal outlet arm whose nozzle 25 Shaped orifices are optionally directed immediately out of the ship's hull or towards the hull, for example sideways or a sloping bottom, for example forward channel.
Herved opnås endvidere en mindre strømningsmod-30 stand i bøjningen og dermed en øget virkningsgrad. Derudover kan drevet ifølge opfindelsen anvendes i fartøjer med krum bund, og da det for en given ydelse optager mindre plads end det kendte drev, er der mulighed for i f.eks. normale kanalfartøjer at anbringe toThis also results in a smaller flow resistance in the bend and thus an increased efficiency. In addition, the drive according to the invention can be used in vessels with curved bottom, and since for a given performance it takes up less space than the known drive, it is possible in e.g. normal duct vessels to place two

2 drev ved siden af hinanden, samtidig med at drevet har mindre \ægt og lavere fremstillingsomkostninger. Anvendelsen af flere drev på samme fartøj er navnlig aktuelt i forbindelse med slæbebåde.2 drives side by side while the drive has less weight and lower manufacturing costs. The use of multiple drives on the same vessel is particularly relevant for tugs.
5 For indbygning i eksisterende skibe af et drev ifølge opfindelsen er propellerpumpen med den svingbare bøjning samt gearhuset og eventuelt et hus, som indeholder kanalerne, fortrinsvis sammenføjet til en indbyggelig konstruktionsenhed, så at indbygningen kan fo-10 retages på enkel og prisbillig vis.5 For incorporation into existing vessels of a drive according to the invention, the propeller pump with the pivotable bend as well as the gear housing and optionally a housing containing the ducts is preferably joined to a built-in structural unit so that the installation can be made in a simple and affordable way.
En udførelsesform for et vandstråledrev ifølge opfindelsen forklares herefter nærmere med henvisning til tegningen, hvor fig. 1 skematisk viser et udsnit af et fartøj 15 med et vandstråledrev ifølge opfindelsen, fig. 2 et tværsnit gennem den nedre del af et fartøj'med drevet ifølge opfindelsen, og fig. 3 i større målestok drevet ifølge opfindelsen uden det omgivende fartøj.An embodiment of a water jet drive according to the invention will now be explained in more detail with reference to the drawing, in which fig. 1 is a schematic sectional view of a vessel 15 having a water jet drive according to the invention; FIG. 2 is a cross-section through the lower part of a vessel with the drive according to the invention; and FIG. 3 on a larger scale driven according to the invention without the surrounding vessel.
20 I fig. 1 betegner 1 et udsnit af et skib, som har en ringe dybgang, dvs. dybden fra vandlinien 2 til skibsbunden 3 er lille. Bunden af skroget er ved hækken, der f.eks. omfatter et trug 4, trukket så højt op, at der i dette trug kan være anbragt et drev 5 25 ifølge opfindelsen på en sådan måde, at det ikke rager ned under fartøjets bund. Skroget er udformet således, at en vandstrøm hovedsagelig uhindret kan strømme bort bagud og/eller eventuelt til siderne. Den højt trukne skibsbund går således over i den øvrige del af 30 bunden, at der også til denne side, altså f.eks. fremad, kun ydes en lille modstand mod vandstrømning.In FIG. 1, 1 denotes a section of a ship having a slight draft, i. the depth from the waterline 2 to the ship bottom 3 is small. The bottom of the hull is at the hedge, e.g. comprises a trough 4 pulled up so high that a drive 5 25 according to the invention may be arranged in such a manner that it does not protrude below the bottom of the vessel. The hull is designed so that a stream of water can flow largely unobstructed backwards and / or possibly to the sides. The high towed ship bottom thus goes into the other part of the bottom 30 that also to this side, ie. going forward, only a little resistance to water flow is provided.
Drevet ifølge opfindelsen består hovedsagelig af en bøjning 6, i hvilken en propel eller en propellerpumpe, f.eks. flere propellere, med lodret akse er dre-35 jeligt lejret. Propellen eller propellerne kan også være erstattet af et andet vandtransporterende aggre- 3The drive according to the invention consists mainly of a bend 6 in which a propeller or propeller pump, e.g. several vertical axis propellers are pivotally mounted. The propeller or propellers may also be replaced by another water transporting aggregate 3

gat. Bøjningen drejer vand, der er suget ind i hovedsagelig lodret retning, til hovedsagelig vandret retning. Bøjningen, som indeholder propellen eller propellerne, er drejeligt lejret i fartøjet. Til drift 5 af propellen findes en motor 8, som driver propellen via gængse og kendte kraftoverføringsmidler, f.eks. over en i et koblingshus 9 værende kobling og/eller et i dette hus anbragt gearskifte, en kardanaksel 10, via et i et gearhus 11 med kendte midler lejret vin-10 kelgear 12, 13, som ses i fig. 3, og via en lodret lejret propelleraksel 14. Propellerakslen bærer propellen 7 på sin nederste ende. Gearhuset 11 er fast lejret i skibet.gat. The bend turns water sucked in in the substantially vertical direction to mainly horizontal direction. The bend containing the propeller or propellers is pivotally mounted in the vessel. For operation 5 of the propeller there is an engine 8 which drives the propeller via conventional and known power transmission means, e.g. over a clutch housed in a clutch housing 9 and / or a gearshift located in this housing, a propeller shaft 10, via an angular gear 12, 13 mounted in a gear housing 11 by known means, as seen in FIG. 3, and via a vertically mounted propeller shaft 14. The propeller shaft carries the propeller 7 at its lower end. The gear housing 11 is permanently enclosed in the ship.
Fig. 2 viser et tværsnit gennem et skib med et 15 drev ifølge opfindelsen. Den ovennævnte bøjning er drejeligt lejret i truget 4. På siderne af truget er der i begge sider af skibsskroget en tunnel 15 og 16, gennem hvilke en fra bøjningen optaget vandstrøm efter valg ledes ud til siden, hvorved man opnår en styre-20 virkning. Tunnelen er udad bøjet lidt nedad for at fratage en eventuelt forstyrrende virkning fra vandstrømmen.FIG. 2 shows a cross section through a ship with a 15 drive according to the invention. The above bend is pivotally mounted in the trough 4. On the sides of the trough there is on both sides of the ship hull a tunnel 15 and 16 through which a stream of water taken from the bend is optionally guided to the side, thereby obtaining a guiding effect. The tunnel is bent outwards slightly downwards to take away any disturbing effect from the water flow.
Fig. 3 viser et snit gennem et drev ifølge opfindelsen. I bøjningen 6's lodrette del er propellen 25 7 med lodret akse lejret på en propelleraksel 14, som er optaget i en lejebøsning 18, der rager ud i bøjningen. På bøjningen er fastgjort f.eks. påskruet en hals 19, som er drejeligt, men ikke længdeforskydeligt lejret i gearhuset 11 eller et dermed forbundet 30 bærerør 11a. På den øverste del af halsen er fastgjort et kronhjul 20, som er i indgreb med et spidshjul 21, som er hovedsagelig horisontalt lejret i gearhuset 11.FIG. 3 shows a section through a drive according to the invention. In the vertical portion of the bend 6, the propeller 25 7 with the vertical axis is mounted on a propeller shaft 14 which is accommodated in a bearing bush 18 projecting into the bend. Attached to the bend e.g. screwed on a neck 19 which is pivotal but not longitudinally displaceable in the gear housing 11 or a supporting tube 11a associated therewith. On the upper part of the neck is attached a crown wheel 20, which engages a pointed wheel 21, which is mainly horizontally mounted in the gear housing 11.
Det fra rorstadet kommende styredrev er sluttet til spidshjulet hovedsagelig på den måde, som kendes fraThe steering gear coming from the helm is connected to the sprocket mainly in the manner known from
DK 155582BDK 155582B
4 rorpropellere. Fra rorstadet kan bøjningen drejes og trykket styres i den til fartøjets styring ønskede retning.4 rudder propellers. From the helm, the bend can be turned and the pressure controlled in the direction desired for the vessel's steering.
Propellerakslen 14 går gennem halsen 19. På 5 den ende af akslen, der ligger over kronhjulet 20, er f.eks. fastgjort et konisk tandhjul 13 af det tidligere nævnte vinkelgear. Tandhjulet 13 er i indgreb med et tanddrev 12, der f.eks. er lejret vandret i gearhuset. Propellen 7 drives på denne måde af mo-10 toren 8 via den allerede omtalte kobling og/eller gearskiftet, kardanakslen, det af tanddrevet og det koniske tandhjul bestående vinkelgear og propellerakslen.The propeller shaft 14 passes through the neck 19. At 5 the end of the shaft which lies above the crown wheel 20, e.g. attached a tapered sprocket 13 of the aforementioned angular gear. The gear 13 is engaged with a gear 12, e.g. is enclosed horizontally in the gear housing. The propeller 7 is driven in this way by the motor 8 via the already mentioned clutch and / or gear change, the shaft, the gear and the conical gear and the propeller shaft.
Bøjningen er udformet strømliniet og som en dyse, dvs. indløbsåbningen er større end udløbsåbningen.The bend is designed to streamline and as a nozzle, ie. the inlet opening is larger than the outlet opening.
15 Hvirvler i bøjningen undgås eller formindskes ved hjælp af én eller flere ledeskovle 22. Indløbs- og/eller udløbsåbningen er udformet lidt tragtformet. Ved udformningen af bøjningen skal der tages hensyn til alle strømningstekniske betingelser.15 Swirls in the bend are avoided or reduced by one or more guide vanes 22. The inlet and / or outlet opening is slightly funnel shaped. In designing the bend, all flow engineering conditions must be taken into account.
20 Til styring af vandet i tilslutning til bøjnin gen anvender man hensigtsmæssigt tunneler, som det fremgår af fig. 2. Man kan dog også støde vandet frit ud, som det er vist i fig. 1 til frem- og bakbevægelse.20 To control the water adjacent to the bend, tunnels are suitably used as shown in FIG. 2. However, the water can also be ejected freely, as shown in FIG. 1 for forward and reverse movement.
I den viste udførelsesform er bøjningen ensidigt 25 lejret. Til større trykkræfter kan en dobbeltsidig lejring eller en supplerende understøtning af den viste lejring være hensigtsmæssig. Således kan der f.eks. i nærheden af indløbsåbningen være anbragt en lejring for bøjningen.In the embodiment shown, the bend is unilaterally mounted. For larger compressive forces, a double-sided bearing or additional support of the shown bearing may be appropriate. Thus, e.g. a bearing for the bend is arranged near the inlet opening.
30 Kræves der større trykkræfter til drift af et fartøj, kan man anvende flere trykgivende bøjninger, f.eks. én eller flere bøjninger ved hækken og/eller anvende en bøjning i så at sige hvert hjørne af fartøjet.If greater compressive forces are required to operate a vessel, several pressure-producing bends may be used, e.g. one or more bends at the stern and / or using a bend in, say, every corner of the vessel.
35 I stedet for som i den viste udførelsesform kan motoren og eventuelt gearet også være anbragt aksialt med eller parallelt til propellerakslen.Instead of, as in the illustrated embodiment, the engine and possibly gear may also be arranged axially or parallel to the propeller shaft.
