Description

Oppfinnelsen angår et vannjetdrivverk som beskrevet The invention relates to a water jet drive as described

i hovedkravets innledning. in the introduction of the main claim.

En innretning av denne type er allerede kjent, hvor motoren med sitt fundament og kanalene må bygges enkeltvis inn i skipets skrog. Lagerhold og montasje av et komplett drivverk er således ikke mulig (NO 133 265). An arrangement of this type is already known, where the engine with its foundation and the ducts must be built individually into the ship's hull. Storage and assembly of a complete drive unit is therefore not possible (NO 133 265).

Det er også kjent en innretning for tverrdrift av A device for transverse operation of

den innledningsvis beskrevne type, hvor pumpen, som suger vannet fra skipets bunn, drives av en elektromotor som er anordnet aksialt til pumpens akse. Bortsett fra at denne konstruksjon er uegnet for de vanligvis benyttede forbrenningskraft-maskiner, opplagres og innbygges heller ikke denne tverrdrift-anordning som enhet i skroget (DE 2 438 305) . the initially described type, where the pump, which sucks the water from the ship's bottom, is driven by an electric motor which is arranged axially to the pump's axis. Apart from the fact that this construction is unsuitable for the usually used internal combustion engines, this transverse drive device is also not stored and installed as a unit in the hull (DE 2 438 305).

Et vannjetdrivverk er riktignok kjent hvor en for-brenningskraftmaskin er anordnet aksialt til pumpen med vertikal akse. Denne konstruksjon er imidlertid kun benyttet på A water jet drive is admittedly known where an internal combustion engine is arranged axially to the pump with a vertical axis. However, this construction is only used on

en påhengsmotor som har en lett motor og hvor således proble-met med innbyggingen i fartøyets skrog ikke foreligger an outboard engine that has a light engine and where the problem of installation in the vessel's hull does not exist

(GB 913 954). (GB 913 954).

Med utgangspunkt i denne teknikkens stand tar oppfinnelsen sikte på å frembringe et vannjetdrivverk av den innledningsvis beskrevne type som enklere kan lagerføres, transpor-teres, monteres og demonteres. Based on this state of the art, the invention aims to produce a water jet drive of the type described at the outset which can be stored, transported, assembled and dismantled more easily.

Oppfinnelsens målsetning oppnås ved hjelp av de i kravets karakteriserende del nevnte trekk. Oppfinnelsen kan benyttes både for drift av to kanaler som fører mot overfor hverandre liggende skipssider, gjennom hvilke vannstrømmen kan ledes valgritt ved hjelp av spjeld eller med en skjerm eller lignende, og også ved konstruksjoner med 360° styring, eksempelvis med minst tre kanaler som fører til en side og minst en hovedfremdriftretning. Således kan altså motoren være montert på en kanal som ligger på tvers av skipets lengdeakse, eller på en kanal som er anordnet parallelt med lengdeaksen . The objective of the invention is achieved by means of the features mentioned in the characterizing part of the claim. The invention can be used both for the operation of two channels leading to opposite sides of the ship, through which the water flow can be directed selectively by means of dampers or with a screen or the like, and also for constructions with 360° control, for example with at least three channels leading to one side and at least one main direction of progress. Thus, the engine can be mounted on a channel that lies across the longitudinal axis of the ship, or on a channel that is arranged parallel to the longitudinal axis.

Oppfinnelsen er beskrevet ved hjelp av figur 1 og 2, hvor figur 1 viser oppfinnelsen benyttet på et tverrutstrål-ingsrør, figur 2 viser oppfinnelsen benyttet på en innretning for drift og styring. The invention is described with the help of figures 1 and 2, where figure 1 shows the invention used on a transverse radiation tube, figure 2 shows the invention used on a device for operation and control.

En propellerpumpe 1 (figur 1) er dreibart opplagret A propeller pump 1 (figure 1) is rotatably stored

1 et hus 2 med vertikal akse, slik at den suger vannet opp fra skipsbunnen på kjent måte (DE 2 215 344, US 3 903 833). Til huset er anordnet kanaler 3, 4 på begge sider, som fører til vannfartøyets 5 styrbord og babord side. Strømmen av det oppsugede vann fra propellerpumpen ledes av en skjerm 6 etter valg til én av kanalene. For dette formål er skjermen sving-bart opplagret om eh horisontal akse 7 i huset og kan betjenes av en hydraulikkmotor 8 eller en annen egnet driftsinnretning for dreining. Propellerpumpen drives av en motor 11 over en vinkelveksel 9, f.eks. en konisk skrueveksel eller snekkevek-sel e.l. og over en kardanaksel 10. Den viste utførelse har en forbrenningsmctor, det kan også være en elektromotor, f.eks. med konstant turtall. I dette tilfelle kan vannets tverrskyv-kraft styres ved at skjermen bare svinges delvis. 1 a housing 2 with a vertical axis, so that it sucks the water up from the bottom of the ship in a known manner (DE 2 215 344, US 3 903 833). Channels 3, 4 are arranged for the house on both sides, which lead to the starboard and port sides of the watercraft 5. The flow of the suctioned water from the propeller pump is directed by a screen 6 to one of the channels by choice. For this purpose, the screen is rotatably stored about eh horizontal axis 7 in the housing and can be operated by a hydraulic motor 8 or another suitable operating device for turning. The propeller pump is driven by a motor 11 via an angle gear 9, e.g. a conical screw gear or worm gear etc. and over a cardan shaft 10. The embodiment shown has a combustion mctor, it can also be an electric motor, e.g. with constant speed. In this case, the transverse thrust of the water can be controlled by swinging the screen only partially.

En av kanalene, nemlig 4, er fast montert til huset One of the channels, namely 4, is fixed to the house

2 og danner sammen med støttene 12 motorens fundament. På denne måte danner pumpen 1, huset 2, den nevnte kanal 4, lede-innretningen for vannstrålen (skjermen 6), drivinnretningen 8 herfor, motoren 11 og dreiemomentoverføringselementene 10, 9 en enhet som for seg kan lagerføres, er transporterbar og monterbar. Ved innføring av kanalen 4 i motorfundamentet oppnås en lettere konstruksjon. 2 and together with the supports 12 form the engine's foundation. In this way, the pump 1, the housing 2, the aforementioned channel 4, the guide device for the water jet (the screen 6), the drive device 8 for this, the motor 11 and the torque transmission elements 10, 9 form a unit that can be stored separately, is transportable and can be assembled. By introducing the channel 4 in the motor foundation, a lighter construction is achieved.

Figur 2 viser bruken av oppfinnelsen ved en 360° styring. En propellerpumpe 21 som også kan være en sentrifugal-pumpe, er anordnet med vertikal dreieakse i en buedel 22 som er svingbar opplagret om den samme akse i et hus 23. Buedelen har L-form slik at det fra dens vertikale del oppsugede vann utstøtes av den horisontale del i ønskede retninger. Svinge-bevegelsen utføres av en motor 24. For dreining av propellerpumpen er det anordnet en motor 25 som avgir sitt dreiemoment til propellerpumpen over en kardanaksel 26 og en vinkelveksel 27. Det utstøtte vann kan ledes i fire retninger, nemlig gjennom åpningene 28 og 29, som enten fører ut i det fri eller kan være forbundet med kanalene, og gjennom en annen åpning som ligger overfor åpningen 29 og derfor ikke er inntegnet. Endelig kan vannet ledes gjennom en kanal 30 som sammen med støtter 31 danner motorens fundament. Alle beskrevne deler danner en transportabel og som én enhet monterbar bygningsdel. Figure 2 shows the use of the invention in a 360° control. A propeller pump 21, which can also be a centrifugal pump, is arranged with a vertical axis of rotation in an arc part 22 which is rotatably supported about the same axis in a housing 23. The arc part is L-shaped so that the water sucked in from its vertical part is ejected by the horizontal part in desired directions. The turning movement is carried out by a motor 24. For turning the propeller pump, a motor 25 is arranged which transmits its torque to the propeller pump via a cardan shaft 26 and an angle gear 27. The ejected water can be led in four directions, namely through the openings 28 and 29, which either leads out into the open or can be connected to the channels, and through another opening which lies opposite the opening 29 and is therefore not drawn. Finally, the water can be led through a channel 30 which, together with supports 31, forms the engine's foundation. All described parts form a transportable building part that can be assembled as a single unit.

Tilslutningsélementene for kanalene og åpningene i vannfartøyet, f.eks. for forlengelsen av kanalene og åpningene, kan være av en hvilken som helst type og ble derfor ikke teg-net. Hjelpeinnretninger som koblinger, kjøleaggregat, batteri, koblings- og styreskap osv. ble ikke inntegnet og henhører selv-sagt også til oppfinnelsens gjenstand. The connection elements for the channels and openings in the water vessel, e.g. for the extension of the channels and openings, could be of any type and was therefore not drawn. Auxiliary devices such as couplings, cooling unit, battery, switch and control cabinet etc. were not included and of course also belong to the subject of the invention.
