Working principle of ship anchor

From the top to the bottom, the structure is anchor shackle, bolt, anchor bolt, anchor handle, anchor wrist, and the symmetrical parts on both sides are called anchor claws. The anchor claw is the most important part of the anchor in the soil. When the ship breaks down, the anchor sinks to the bottom of the water under the traction of the anchor chain. At the bottom of the water, the plane of the anchor wrist will be perpendicular to the bottom of the water due to the action of the anchor bolt, and the anchor claw will contact with the bottom of the water.
The length of the ship's anchor chain is often greater than the water depth, so the anchor chain in the underwater part is lying on its back. When the ship is disturbed (such as the top wave), the anchor chain will be pulled, and the anchor in the underwater part will be affected by a horizontal force at the connection of the anchor chain. At the same time, the gravity of the anchor itself will act on the contact point between the anchor claw and the water bottom (point C in the figure). The combination of the two forces will make the anchor under the syncline Movement, this is the process of anchoring into the soil. After the anchor is pulled into the bottom of the water, it can provide the ship with the ability of berthing. It should be noted that this ability can be achieved not only by one anchor, but also by a long chain.
