Definitions

• the invention relates to an auxiliary drive device for ships according to the preamble of claim 1.
• auxiliary drive device shown therein is either purely vertically from the hull down movable. This known drive device can also be used in the sense of a transverse thruster.
• auxiliary drive in particular as a forward drive, this known drive device under the ship's bottom is extendable or pivotable. The pouring takes place in the midships plane, wherein in the swung-out state, a rotatability of the drive device about a vertical axis should be possible.
• a disadvantage can be considered in this known auxiliary drive device that in the region of the ship's bottom relatively large recesses for vertical Ver- ability or swiveling ability must be present, whereby the flow dynamics is significantly impaired.
• auxiliary drive device can be used in the sense of an auxiliary drive only in a position in which these auxiliary is placed half of the ship's bottom. So a much larger draft of the ship has to be considered.
• auxiliary drive is known from US Pat. No. 3,517,633.
• the propulsion unit is indeed placed within the hull in the bow area and rotatable about a vertical axis.
• a disadvantage is the insufficient flexibility with regard to a directional drive in this propulsion unit, since only one transverse channel and one longitudinal channel are provided. The mode of action in the longitudinal direction is also not efficient due to the almost downwardly directed exit region for the longitudinal channel.
• the invention is based on the object to provide a suitable especially for large vessels auxiliary propulsion device, the significantly improves the maneuverability of the ship, which also applies to shallow waters and can also be used as an auxiliary drive or as an additional drive, eg to increase the speed.
• An essential core idea of the invention can be seen to not only improve the maneuverability of the ship in the transverse direction with an auxiliary drive device, but also to use this auxiliary drive device as a whole for improving maneuverability in the forward direction, if necessary, and also in its auxiliary drive device To arrange working positions within the maximum cross-sectional plane of the ship, so that the normal draft of the ship determines the navigability of waters.
• the booster device can perform a dual function, e.g. can be arranged as a transverse jet propulsion, bow or stern side and can also be used for different directional orientations for propulsion.
• the drive device according to the invention is therefore particularly suitable for large tanker or large container ships, as an auxiliary drive for problematic situations, with maneuvering forces, especially in the transverse and / or longitudinal direction of the ship, are required, and considered in shallow waters only the corresponding draft of the ship must become.
• the invention can be realized in two essential alternatives.
• a pendulum-type suspension of one or more propulsion units usually arranged one behind the other in the longitudinal direction of the ship in the midships plane is possible.
• the corresponding pendulum arrangement which normally has only one propulsion unit, expediently as a drive nacelle with two drive propellers, can optionally be swung out only on one side.
• a swiveling on both sides within a pendulum box from a central stowage position in the midships plane both to starboard as well as to port outside the hull can be realized.
• the overall device is expediently provided in the region of the narrower ship hull, in the bow or tail.
• the auxiliary drive device can be used in the central position or stowed position, wherein advantageously an electromechanical or electric motor drive is provided.
• the auxiliary drive device is swung pendulum-like and the corresponding Propulsionsü nor- o mally rotated by about 90 or more, so that a
• the propellers of the propulsion unit lie in this propulsion arrangement outside the hull, but still within the maximum cross-sectional plane of the ship. In this way, a high efficiency of the propulsion is achieved fluidically, without the maximum draft of the ship is still increased.
• the propulsion units designed as drive gondolas are mounted rotatably, so that other angles of attack are also possible.
• Dual propulsion units in the narrow area of the bow increase auxiliary propulsion power, improve redundancy, and can also be used on one side of the vessel when needed.
• the corresponding propulsion unit can be extended in an arcuate manner or substantially horizontally on or on a rail system, from a central stowed position to one side or both sides, similar to previously known transverse beam channels in such a transverse channel. After extension or unfolding of these propulsion units to the outside of the hull, the same function, as previously described, achievable.
• auxiliary drive device considerably improves the safety and maneuverability of these ships.
• the operation of the device according to the invention can therefore be on the one hand in the sense of a bow thruster or after swinging and swinging out as an auxiliary drive for additional maneuvering forces.
• a reserve or emergency operation eg for the return journey of a ship, the device can be used.
• the pulsion unit can be moved on or on horizontal or curved rails from a central stowage position, with folding-out systems securing the working position outside the protective sheath.
• the safety is further increased by the redundancy drive.
• Two-sided provided propellers on corresponding drive gondolas improve the flow characteristics and thus the introduction of forces into the water.
• end flaps or slides are preferred for fluidic reasons. These shutters are opened when using the Propulsionsticianen outside the hull and set in a fluidically good location.
• the pendulum box (s) are isolated for safety reasons.
• auxiliary drive device in the region of the propulsion unit can therefore be equipped with propellers or designed as a POT drive.
• Figure 1 is a partial longitudinal section through the bow region of a ship with two successively arranged auxiliary drive devices.
• Fig. 2 is a schematic representation of the ship area of FIG. 1 in a horizontal section
• Fig. 3 is a schematic representation of the ship area of Fig. 1, 2 in a vertical cross-sectional plane in the region of the auxiliary drive device.
• FIG. 1 shows, in a simplified representation, the bow region 2 of a ship 1, the horizontal lines provided in the region of the bulge bend 3 and the ship bottom 6 approximately showing the water lines 35.
• the auxiliary drive device 10 is provided, which in this example has two successively arranged propulsion units 11 and 12.
• propulsion units 11, 12 are arranged within a partitioned drive box 31, which may be divided by a dividing wall 32 into two separate chambers.
• the propulsion units 11, 12 are in this case pivotally mounted in the pendulum axis 15 extending approximately in the midships plane.
• the drawing of Figure 2 shown in the manner of a horizontal section through the bow area 2 shows the contours of the water lines 35 with the narrow Bülstbug 3, which widens transiently aft in the hull.
• the two pendulum boxes 31 are sealed and provided sealed off from the hull.
• the corresponding transverse channel 27 of the auxiliary drive device 10 is, as can be seen more clearly in FIG. 3, provided in the manner of an arc segment in the case of a pendulum arrangement 14.
• the transverse web 16 can also extend substantially horizontally.
• the pendulum box 31 is shown schematically with broken lines, which merges outwardly into the corresponding contour of the hull 5 and the lower region can form the conclusion of the transverse channel 27.
• the pendulum arrangement 14 is shown in its stowage position 19 in hatched plane 8 in hatched representation. This stowage position also represents the bearing arrangement, in which the corresponding propulsion unit can be used as a transverse thruster 18.
• propulsion units 11, 12 Fig. B. a propulsion unit 11 on the one hand, to starboard, are swung over the hull 5 out, while the other propulsion unit 12 are swung to the port.
• the corresponding propulsion unit 11 which is designed as a drive nacelle, is subsequently rotated, as indicated by the arrow 39, o by at least 90 °. In this then reached position, a propulsion or a reverse-acting force can be achieved by the propellers of the propulsion unit 11 and 12, respectively.
• auxiliary drive device 10 with two propulsion units 11, 12, these can, as shown in the example of Figure 3, are used very well in the swung-out arrangement as auxiliary drives for the ship 1.
• the appropriate Rotations°. Angular position and orientation of the propeller axes of the propulsion units depends here on the outer contour of the hull 5 and is adjustable according to the requirements.
• a transverse beam effect for the bow area of the ship can also be achieved outside the hull or a flow dynamic adjusted propulsive action can be adjusted taking into account the course of the hull in this area.
• the invention is therefore advantageously suitable for ships, in particular screw-in boats, which must have a high safety standard and must be maneuvered well in shallow waters.
