Description
Technical field
The present invention relates to tow stress detection technique field, specially a kind of tow stress detection and early warning system.
Background technology
Power tool of the Cable rope for ship as ship mooring, traction, fixation etc., the importance in navigation operation need not be put
Doubt.If disconnected cable accident occurs for ship, the accident for touching harbour or surrounding ship may be not only caused because of ship drift out of control, also
Casualties may be caused, cause huge economic losses and social influence.Study carefully its essential reason and be more than cable for external force suffered by hawser
Rope working strength.Often show the following aspects：1st, hawser and ship side friction are inevitable, and it is disconnected that friction make it that hawser occurs
Silk, so as to hawser intensity decreases；2nd, multiple cable stress are uneven during ship berthing, and external force is all undertaken by part hawser and exceeds it
Working strength；3rd, the influence factor of ship mooring force is sufficiently complex, is both influenceed by ship type, hawser parameter and harbour arrangement, and by
The containing of the various dynamic factors factors such as wind, wave, stream.With the development trend of larger-sized vessel and berth deep water, hawser institute
Being subjected to external force increasingly increases, while ship berthing difference harbour, and the hydrologic condition and meteorological condition in berth are changeful, hawser
Stress real-time change, and operator on duty is difficult to find and adopt an effective measure in time；4th, ship loading and unloading goods and harbour tide are common
Influence so that the floading condition of ship changes at random, causes cable stress also random change, and aggravate hawser and ship side and checking bollard therewith
Friction.At present, the monitoring of ship berthing cable stress relies primarily on sailor on duty periodically inspection hawser, only with its sense organ and warp
Test and occur to judge that cable stress state carrys out pre- anti-breaking cable, this undoubtedly has very big uncertainty.Because preventive effect by
The very big restriction of many factors such as personnel specialty experience, muscle power and sense of responsibility.Such as：Whether different personnel are uniform to a plurality of hawser
The assurance of stress is different；Different operators on duty is different to the berthing attention degree that cable stress monitors when on duty；Different values
The adjustment frequency difference of class personnel to berthing hawser on duty etc..Therefore, hawser accident turns into numerous ships during ship berthing
The immediate cause that accident occurs during pool.In recent years, shipping safety more enjoys outer concern in the industry, and break cable this problem of ship accounts for
Sizable proportion in shipping work causes of incident, causes massive losses.How ship mooring operator on duty is overcome to cable
Restrict load-bearing monitor subjectivity and it is empirical the problem of, turn into the pressing problem that pre- anti-breaking cable accident is badly in need of solving.
