Embodiment Construction

[0013] figure 1 A simplified diagram of an anchor winch of a vessel 100 according to an embodiment is shown. The figure shows only components necessary for understanding the various embodiments. The watercraft 100 may be, for example, a steamer, rowboat, raft or generally a boat designed for waterway transportation. The exemplary winch includes a winch drum 20 for winding the windable intermediate 10 , the winch drum 20 being rotatable about an axis of rotation 21 . The windable intermediate 10 may comprise, for example, a cable, rope, wire or chain, or combinations thereof. The rollable intermediate 10 has an anchor 11 connected to an end of the rollable intermediate 10 . The term anchor generally refers to a device that can be used to connect a vessel to the bottom 300, ie the bed, of a body of water, such as a sea, ocean, lake, river, strait or canal or the like. By winding the windable intermediate 10 by the winch drum 20, the anchor 11 can be raised or lowered dependi...

Abstract

A method for operating an anchor winch and an anchor winch for a vessel (100), comprising a winch drum (20) and an electric drive (30, 40, 41) configured to raise the anchor (11) by driving the winch drum (20) with an electric motor (30), to detect a first increase in a torque produced by the electric motor (30), which is higher than a first predetermined torque threshold, a subsequent decrease in the torque produced by the electric motor (30), which lasts for at least a predetermined time threshold and during which decrease a rate of decrease is within a predetermined range, and a subsequent second increase in the torque produced by the electric motor (30), which is higher than a second predetermined torque threshold, and, in response to detecting the second increase, determine that the anchor (30) has risen above a water surface (200) of a body of water.

Description

technical field [0001] The invention relates to a method for operating an anchor winch and to an anchor winch. Background technique [0002] An anchor winch may be used to lower a ship's anchor to and raise a ship's anchor from the bottom of a body of water. The vessel may be, for example, a steamer, a rowboat or a boat generally designed for water transport. Examples of bodies of water include seas, oceans, lakes, rivers, straits, canals, or any part of the foregoing. [0003] The anchor winch may comprise a winch drum which is rotatable about its axis of rotation and which may be used to wind the intermediate windable to raise or lower the anchor connected to the end of the intermediate windable. Coilable intermediates may include, for example, cables, ropes, wires or chains. The anchor winch may also include a motor configured to rotate the winch drum about its own axis of rotation during winding or unwinding of the windable intermediate. Thus, by suitably driving the...
