How Anchor Works
The structure from top to bottom is the anchor shackle, bolt, anchor rod, anchor handle, anchor wrist, and the symmetrical parts on both sides are called anchor claw. The anchor claw is the most important part of the anchor to grab into 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, due to the action of the anchor rod, the plane of the anchor wrist will be perpendicular to the bottom of the water, and the anchor claw will be in contact with the bottom of the water at this time.
The length of the anchor chain of the ship is often longer than the water depth, so the anchor chain on the bottom part is in a flat state. When the ship is disturbed (such as the top wave), the anchor chain will be pulled, and the anchor on the bottom will be connected at the anchor chain. Under the action of a horizontal force, at the same time, the gravity of the anchor itself acts on the contact point between the anchor claw and the bottom of the water (point C in the figure), and the combination of the two forces makes the anchor move diagonally downward, which is the process of the anchor entering the soil. After the anchor is pulled into the bottom of the water, it can provide the ability to moor the ship. It should be noted that this ability can not only be completed by an anchor, but also a long anchor chain also plays an important role.
