What are the functions of the anchor

The main function of the anchor is to fix and stabilize the ship. From the following aspects.
1. For the anchor to work, the most basic condition is to hook something on the seabed.
If the anchor chain is not long enough, the anchor will not work.
If the seabed is flat, or the anchor hooked is not fixed, or the hook is not strong enough, if the wind is calm, it is fine, but once the waves are too large, the anchor cannot hook something, and the anchor will lose its function. , This is called "walking the anchor". It is very dangerous for the ship to walk away during the anchoring period, because the main engine is usually stopped when the ship is anchored. If you start the ship immediately, it will take time. dangerous. Therefore, there is the concept of anchorage. Anchorage, the implication, is relatively rough under the sea, and in addition, it must be able to shelter from the wind.
2. The weight of zinc alloy anchor the anchor chain is negligible for the ship, and that little friction will not play a big role.
In addition, if you pay attention, generally speaking, when the ship is anchored, the anchor chain is straight, do you think there will be any friction in the anchor chain at this time?
If you are at the seaside, you will find a lot of small fishing boats, their anchor chains are thick ropes.
3. Viewed from the top of the boat, the anchor chain is straight, but it is underwater
There is a section that is nearly parallel to the seabed (actually close to the seabed)
The anchor provides grip, which is then transmitted to the ship through the anchor chain
In this way, it can resist the influence of external loads of ocean currents, wind and waves on positioning.
The reason why there is a section close to the bottom of the sea
is to take into account the influence of the force
Think about it, an anchor, the anchor chain is straight and easy to pull the anchor.
And there is a section close to the seabed, which can provide a margin
It is possible to a certain extent.
The weight of the anchor is not large, but the size of the anchor is specified for the size of the ship.
This is due to the holding force that the anchor can generate and its own inertial force.
Anchor chain friction also plays a role
In general, if you encounter a big storm in the deep sea, you basically only have to look at the meaning of God.
Anchor is an indispensable equipment to ensure the safety of the ship, and the anchor mainly has an anchor crown. It is composed of pin shaft, anchor claw, anchor handle, anchor rod (also called cross rod or stabilizer rod) and anchor shackle.
The ancient anchor was a large stone, or a basket full of stones, called an "anchor". Anchorites are sunk to the bottom by ropes, and the boats are moored according to their weight. Later, there were wooden claw stone anchors, that is, wooden claws were tied on both sides of the stone, and the ship was moored by weight and grip. There have been records of metal anchors in the Southern Dynasties of China. Ancient Chinese sailboats used four-claw iron anchors, which have excellent performance and are still used in sampans and boats.
