Definitions

  • the invention relates to an underwater propeller drive according to the features of the preamble of the main claim.
  • a propeller is arranged in a tube tunnel lying transversely to the ship's longitudinal axis in the bow area.
  • a drive motor inside the ship drives the propeller via a shaft perpendicular to the transverse channel and a gear nacelle.
  • the gear nacelle which has to accommodate the spur and bevel gears required for the transmission of the torques, therefore has correspondingly large radial dimensions which greatly narrow the cross section of the tube tunnel.
  • the installation and removal of this transverse jet drive requires docking, or at least a corresponding trimming of the ship.
  • the electrical and also the hydrodynamic efficiency of such drives are relatively poor.
  • Submersible pumps work on a similar principle.
  • a screw propeller is also installed in the delivery line.
  • the propeller can be driven with an underwater motor with or without gear. With a flooded motor, such pumps can also be used for great depths.
  • the engine and transmission lie in the jet area of the propeller.
  • the beam cross section is greatly reduced.
  • an electrically driven propeller is known from DE-PS 688 114, in which the wing ends of the propeller blade are connected to a peripheral ring which receives the electrically passive part (rotor) of a drive motor.
  • the electrically active part (stator) is located in a nozzle receiving the propeller.
  • the object underlying the invention is to be seen in creating an underwater screw propeller drive which can be installed and removed in a tube tunnel, ensures a maximum flow cross section and thus good efficiency, and can be braked in a technically simple manner when not in use and when the flow is not wanted.
  • the particular advantages of the drive according to the invention are that it is small in volume, easy to replace and maintain, and has good efficiency.
  • a bow thruster for maneuvering watercraft which, with its approximately cylindrical drive housing enclosing the drive unit, is inserted into a transverse channel which is open on both sides and is arranged in the bow of the watercraft below its flat bed line in such a way that the propeller lies approximately in the radial central plane of the transverse channel, to which the drive unit is formed symmetrically.
  • a guide vane ring is provided on each side of the propeller, at least one of which connects the bearing housing for the propeller hub to the drive housing in a rotationally fixed manner.
  • the drive housing has an opening on the casing side which opens into a hollow guide vane through which drive means for driving the propeller are laid.
  • the overhung propeller hub is designed as a socket that is open on one side and encloses the drive motor. Its drive shaft is non-rotatably connected to the bottom of the socket.
  • the two guide vane rings are axially close to the propeller.
  • the drive motor is a hydraulic motor, the hydraulic lines of which are guided through the hollow guide vane.
  • the underwater propeller drive according to FIG. 1 can be used as a unit in a tube tunnel for transverse jet drives of ships or in delivery lines for deep-sea pumps.
  • the assembly 1 consists of an axially short, cylindrical housing 2, which is open at the end faces. Arm crosses 3, 4 are connected to the housing 2 and accommodate bearings 5, 6 for the shaft 7 of a screw propeller 8.
  • the wing ends of the propeller 8 are connected to a ring 9, in which the rotor 10 with permanent magnets of an electric drive motor is inserted distributed over the circumference.
  • the ring 9 is received by a recess 11 in the housing 2.
  • the stator 12 is also arranged in the housing 2, opposite the rotor 10, distributed over the circumference of the housing 2.
  • a power cable is connected to the stator 12, which is located in a groove 13 of the housing for the purpose of simplified assembly of the unit and is led at the installation location through a tunnel opening to a connection box outside the water area.
  • Figure 2 shows a section of a transverse channel in a ship with a structural unit, here in the form of a double propeller, which rotate in opposite directions in order to better utilize the swirl energy of the one propeller and to increase the thrust effect.
  • 15 denotes the side wall of the ship, which has an opening 16 below the dashed line of the ship's water.
  • a pipe tunnel 17 is laid from this opening 16 to a corresponding opening in the opposite ship's wall.
  • the propeller unit 18 can now be assembled in a tube section 19 in a workshop. The tube with the assembly 18 is then transported to the ship and through the side opening 16 into the tube tunnel 17 inserted, up to an annular shoulder 20 in the pipe 17.
  • connection box 23 which is above the ship's water line lies. From this junction box, the connection leads either to the infeed point or to a short circuit via resistors. In this way, when the transverse jet drive or the submersible pump is not in operation, the regenerative braking of the engine prevents the propeller from running uncontrolled as a result of the inflow and the resulting noise.
  • Another possibility of assembling the assembly 18 is to insert only this assembly through the side opening 16 into a pipe tunnel and to fasten it in the predetermined position.
  • the riser pipe for the cable connection can be arranged directly above the assembly. The course of the riser pipe will have to be adapted to the ship's premises.
