Description
Technical Field
The invention relates to the field of marine equipment, in particular to a mooring rope in-place sensing device based on a magnetic induction principle.
Background
The towed line array sonar is flexible cable-shaped detection equipment, is hundreds of meters to thousands of meters in length, is used for ocean acoustic detection, and needs to be reeled and released by a winch on a mother ship when in use. Along with the increase of unmanned and remote operation requirements of the winch, a reliable generation device for recovering the in-place signal is needed, so that the in-place signal is sent out when the recovery is finished, and the winch is controlled to stop automatically in time.
Currently, in a towed linear array retraction system, the following methods are mainly used for generating an in-place parking signal:
1) and in the cable length counting mode, the length of the released drag line array is calculated through the rotation angle information of a winch drum or other transition pulleys, and the winch stops when the length is in place during recovery. The disadvantage of this method is that the actual positioning error of the towed linear array is larger due to the variation of the length of the towed linear array and the error of the cable length technology, which causes the problem that the towed linear array can not be completely recycled or can be recycled excessively.
2) Utility model 201720600858.0 "control system for cable recovery" discloses a device for realizing in-place control based on the principle of magnetic induction. The main principle is as follows: when the rotor arranged on the cable passes through the stator core, the coil winding generates alternating current, so that parking control is realized. A disadvantage of this solution is that the magnitude of the alternating current generated is influenced by the speed of movement of the cable.
3) The mechanical stopping signaling mode has been put into practical use, an additional streamline-shaped towing body is installed at the tail end of the towing line array, the diameter of the towing body is larger than that of the towing line array, the signaling mechanism is of a horn-shaped structure and is internally provided with a sliding sleeve capable of moving axially, and when the towing body is recovered in place, the towing body enters the tubular signaling mechanism to drive the sliding sleeve to move, so that the travel switch is triggered. The disadvantages of this approach are: firstly, the mechanical displacement of the slip ring is prone to jamming, especially in silt and corrosive environments, and therefore requires good maintenance; secondly, can produce the scraping with the sliding sleeve when cable battle array retrieves, probably cause the sliding sleeve malfunction under some circumstances, produce the error signal.
