摘要: An active stabilizing device for a primary damping of rolling movements of a ship or other watercraft includes at least one positioning device including a drive journal and a stabilizing fin having a stabilizing surface and a root, the drive journal being attached to the stabilizing fin at the root, the stabilizing surface having a leading edge and a trailing edge and being configured to be disposed underwater. The positioning device is configured to simultaneously pivot the stabilizing fin about a pivot axis by a pivot angle and rotate the stabilizing fin about an axis of rotation. Also, a method of operating the active stabilizing device.

摘要: A reactor configured to clean ballast water on ships includes a reactor housing having an inlet and an outlet and a reactor tube in the reactor housing providing a fluid connection between the inlet and the outlet. The reactor tube includes an inner wall having a plurality of rounded recesses extending longitudinally from a first end of the reactor tube to a second end of the reactor tube, and the rounded recesses each have a substantially constant cross section from the first end of the reactor tube to the second end of the reactor tube. A radially inwardly projecting ridge extends between each circumferentially adjacent pair of the rounded recesses.

摘要: A cover device for at least partially closing an underwater opening in a hull of a watercraft includes a variable-volume hollow-chamber lip assembly including at least two hollow-chamber lips and one buoyancy body. The at least one hollow-chamber lip is volume-variable by supplying a fluid to or removing a fluid from an interior thereof, and the at least one hollow-chamber lip assembly is shiftable between an expanded state and a contracted state by supplying or removing the fluid.

摘要: A method for treating a liquid loaded with ingredients includes injecting the liquid into a reactor vessel such that a circular movement is imparted to the liquid and such that a concentration of the ingredients in a region of a peripheral wall of the reactor vessel increases in a direction from a reactor inlet to a reactor outlet, impinging ultrasound waves having a first intensity and/or ultraviolet radiation having a first intensity on the liquid in a first portion of the reactor vessel, and impinging ultrasound waves having a second intensity and/or ultraviolet radiation having a second intensity on the liquid in a second portion of the reactor vessel. The concentration of the ingredients in the first portion is less than the concentration of the ingredients in the second portion and the first intensity is less than the second intensity. Also a reactor vessel.

摘要: A device for the roll-stabilization of a watercraft in motion, at anchor, or at zero speed, and/or for influencing the course of the watercraft, includes a fin-carrying shaft on which a guide fin is disposed. For changing an actual angle of attack of the guide fin in the water, the fin-carrying shaft is drivable by an electromechanical drive unit, and the drive unit is disposed on the hull using a base. An electromechanical drive unit is configured with a synchronous motor that drives the fin-carrying shaft using a reducing eccentric transmission. The device thereby has a significantly reduced installation space requirement, causes only slight operating noises, and is also optimally electronically regulable.

摘要: The invention relates to a cover device for at least sectional closing of an underwater opening in a hull of a watercraft, in particular an opening of a transverse channel of a thruster. According to the invention the cover device includes at least one variable-volume hollow chamber lip including at least one buoyancy body, and the at least one hollow chamber lip is shiftable into an expansion state or into a shrinkage state by supplying or removing a fluid, in particular air. As a result of the variable-volume or inflatable cover device a more reliable and simultaneously lower-maintenance operation of the cover device is given. In addition, the invention has a thruster, in particular a bow or stern-thruster, as subject matter.

摘要: A shaft lock includes a radially inner rotor part that is coaxially connected to a shaft having a rotational axis and a fixed stator part that at least partially encloses the rotor part. In a locking state and in a holding state, an interference-fit connection between the rotor part and the stator part is produced by a plurality of locking bodies, and the interference-fit connection is cancelable by a transition into an unlocking state. To produce the interference-fit connection, each of the plurality of locking bodies are partially engageable in an interference-fit manner in a respective receiving geometry of the rotor part by rotation of a substantially hollow-cylindrical locking ring that coaxially encloses the stator part in a partially radially outer-lying manner.
