Description

Technical Field

[0001] The utility model relates to the technical field of early warning devices, in particular to a ship anchor dragging early warning device and a buoy. Background Art

[0002] Anchor dragging occurs when an anchored vessel is pushed by external forces such as strong winds and rapids, causing the anchor's holding coefficient to drop sharply, leading to the vessel's dragging of the anchor. Causes of anchor dragging include poor bottom conditions, insufficient anchor weight, a short or tangled anchor chain, improper anchoring techniques, poor anchor engagement, increased wind and waves, and swaying. Anchor dragging can lead to accidents such as grounding, grounding, collision, or capsizing. Therefore, watchkeepers must diligently perform anchor watchkeeping, promptly detect anchor dragging, and implement effective emergency measures to prevent accidents. Methods for determining anchor dragging include surveying the anchor position, observing swaying, monitoring the anchor chain, and deploying a sounding hammer. Once anchor dragging is detected, the officer on duty must take effective measures: ① Immediately drop another anchor. ② Avoid recklessly slackening the anchor chain. ③ Prepare the vessel and notify the captain. ④ Hoist and sound the "Y" signal or use VHF or other communication methods to promptly warn other vessels. ⑤ If the anchor continues to drag after starting, weigh anchor and re-select an anchorage if conditions permit. ⑥ When the situation is urgent or time is tight and it is not possible to wind up the anchor chain, an anchor mark should be attached, the anchor chain should be loosened and the anchor should be abandoned.

[0003] Currently, most ship anchor dragging warnings are completed by ship staff on anchor duty. The staff on duty take turns to watch over the ship 24 hours a day and solve the problems only after they are discovered. The labor intensity is high and the warning effect is not ideal. Therefore, we propose a ship anchor dragging warning device and buoy. Utility Model Content
