Definitions
- the invention relates to a water jet drive for watercraft.
- waterjet drives have been found to improve maneuverability, which are preferably arranged on the bow side in the bottom area.
- Such water jet drives which are also referred to as bug jet systems, comprise a housing which can be built into the respective vehicle floor and which contains at least one propeller (or a pump impeller) which acts on the water supplied via a housing inlet on the bottom and, for example, via a manifold and channels in the latter Direction radiates, or by at least one flush and usually 360 ° swiveling outlet opening under the ship floor controls all around.
- the axis of rotation of the propeller or the pump impeller extends either in the horizontal or vertical direction.
- Water jet drives with a vertically aligned axis of rotation require a relatively shallow draft for air-free working for the propeller (or pump impeller) which is horizontally arranged above a floor inlet, but have, among other things, the disadvantage that such drives at low water depth (ie less than about 50 cm of water under the keel) generate a strong suction due to their suction effect directed directly to the bottom, which increases the ship's resistance and impairs the thrust development or causes it to collapse completely , if foreign objects that are increasingly sucked in clog the protective grille that is usually present. Furthermore, the risk of damage increases because small foreign bodies pass through the protective grid like a sieve and can increasingly get into or between the blades.
- the invention is based on the object of specifying a water jet drive with a propeller pump for watercraft, in particular for displacement vehicles, which is as simple and inexpensive to produce as possible, which with optimized flow during maneuvering and with increasing travel produces an efficient thrust and better flatness.
- the invention is essentially based on the idea of arranging the propeller shaft of the water jet drive on the pressure side of the respective propeller pump in a commercially available 90 ° pipe bend in such a way that the propeller axis of rotation is not vertical or horizontal, but at an angle of inclination ⁇ of 20 ° to 50 °. preferably between 25 ° and 40 ° - with respect to the base plate as a horizontal base and to add an outlet housing section to the other, obliquely downward-pointing end of the pipe bend and to provide it with a rotatable bottom deflection grille in order to provide the outlet jet and thus the propeller thrust under the bottom of the water jet drive to steer all around in all directions.
- the water jet drive consists of a housing unit which can be inserted into the ship's bottom and which is formed from at least four housing sections which are connected to one another: a floor-level inlet which is preferably designed for displacement vehicles.
- Housing section which is concentrically connected to a tubular pump housing section with an axis inclined to the horizontal.
- an arc-shaped housing section is attached under the same inclination, which serves as a housing base with an integrated propeller shaft bearing and which is preferably formed by a commercially available 90 ° round arch, but can also be designed in some other way.
- a floor-level outlet housing section is attached to the other, obliquely downward-pointing arch end, in which there is a bearing for a controllable floor deflection grating.
- the inlet housing section is designed according to special shape and cross-sectional features that reflect the different inflow conditions (as found in the suction - differentiate between inlet and operation in stationary pumps in a similar way).
- the inlet housing contour above the inlet opening assumes a trapezoidal cross-section with rounded corners until the corner radii form a curved cross-section with a circular radius to which a conical pump inlet nozzle attaches.
- this inlet housing section By aligning the contours of this inlet housing section with the main direction of travel (ie straight ahead) and at the same time also with lateral or inclined If flows are recorded like a funnel, the water is optimally fed to the propeller inclined to the flow.
- the tubular pumps arranged between the inlet - housing section and the pipe bend - housing section which consists of a particularly corrosion and. Wear-resistant material is provided, forms a propeller pump as a central pump housing with at least one propeller and stator blades fixedly arranged behind it, which convert the swirl energy into flow energy and at the same time serve as webs for supporting the central bearing hub.
- a propeller pump as a central pump housing with at least one propeller and stator blades fixedly arranged behind it, which convert the swirl energy into flow energy and at the same time serve as webs for supporting the central bearing hub.
- An alternative support for the bearing hub e.g. with round cross-section spokes etc. is also conceivable and included.
- the water jet drive is to be driven by an internal combustion engine
- the motor and transmission can be aligned with one another and fixedly arranged on a common base frame, which in turn is then based as an elastically mounted unit on the brackets attached to the water jet drive.
- the reversing stage of this marine gear can be used for rinsing cleaning of the intake protection grille.
- the inlet housing section can be designed in special installation-specific variants. For example, by making the entry level of the front or a side entry edge somewhat higher and / or. by varying the inclination of the front or a side housing surface, flat open areas can be created in the bow area or on the side of a watercraft, so that additional (air-free) water can flow in directly from the front or from the side. (Among other things, for pontoon or double-ended ferries with lateral or diagonal jet installation.)
- the water jet drive according to the invention can be used for different types of watercraft and for different purposes, e.g. as maneuvering u.
- Auxiliary system and / or as a main drive system can be used at various positions in the vehicle floor.
- the main vehicle types are inland waterway vessels, such as freight, passenger and work ships as well as ferries, landing craft, government vehicles and those with increased requirements for holding positions, e.g. Fire-fighting boats, diving ships, measuring u. Laboratory ships etc. into consideration.

- the propeller axis of rotation 9 and thus also the propeller shaft 11 are arranged at an inclination angle ⁇ of preferably 28 ° with respect to a horizontal base which is formed by the base plate 20 of the housing unit 3.
- a pipe bend 6 is attached to the pump housing section 5, which serves as a base for mounting the propeller shaft 11 and which can be a commercially available 90 ° round bend.

- the housing unit 3 can be designed with an inspection cover over the empty water line (not shown), which enables inspection and cleaning of the inlet area from the machine room.
- the water is optimally supplied to the propeller 10 inclined to the flow.
- side surfaces of the inlet housing section 4, which are flared outwards, oblique or lateral inflows are also recorded with a funnel-like effect.
- the contours of the inlet housing section 4 are chosen such that the profiles of the tunnel cross sections 21, 22 in FIG. 4 steadily increase their height and their upper corner radii until they form a tunnel with a circular curvature to which a conical pump inlet nozzle 23 is attached. Below the axis of rotation 9 of the propeller, the contour of the pump inlet nozzle 23 decreases until it merges downwards into the base plate 20.
- Alternative designs are conceivable and included.

- the tubular pump housing section 5 arranged between the inlet housing section 4 and the pipe bend 6 forms the pump housing with a narrow radial gap around at least one propeller 10 and together with the guide vanes 26 arranged behind it, which convert the swirl energy into flow energy and at the same time to support the bearing hub 27 serve, the Propelle ⁇ umpe 8.
- an alternative hub support for example with unprofiled spokes (instead of 26) is conceivable and included.
- the pro- the bearing hub 27 on the peller side preferably contains a conventional water-lubricated propeller shaft plain bearing 39.
