There are four kinds of ship anchors, they are: rod anchor, rod anchor, high holding power anchor and special anchor. 1. There is an anchor Also known as the navy anchor, this anchor is an early anchor, also known as the navy anchor, the anchor structure is simple, grab weight ratio is large, grab the bottom stability is good, but the anchoring operation and collection is not convenient, the upwarped anchor is easy to tangle the anchor chain and scratch the bottom of the ship, this anchor is not easy to be used as the bow anchor of the merchant ship, generally used for small boats or sailboats. 2. Rodless anchor Also known as mountain anchors, commonly known as Hall anchors and Spaker anchors, are rodless anchors with active anchor flukes (about 45 degrees of rotation along the anchor stem), and the anchor rod and anchor arm of the rodless anchor are cast separately. Anchor claw, anchor crown and anchor arm cast into one. The anchor shaft is inserted into the rectangular hole of the anchor crown, and the pin shaft and the cross pin are positioned in the two semi-circular grooves at the lower part of the anchor crown to realize the purpose of turning the anchor shaft. 3. Large holding power anchor The high gripping power anchor combines the advantages of rod anchor and rod anchor, and is generally a rod rotary fluke anchor. Commonly used are Martenberg anchor, Danforth, which is characterized by wide and long claw, deep biting soil, good stability, so as to obtain a larger gripping force, gripping weight ratio of up to 11-17 times. But the strength of the anchor claw is weak and easy to deform. Because of the large resistance unearthed, it is generally only suitable for engineering ships, and some do spare anchors or tail anchors. 4. Special anchors A special purpose anchor, often used for permanent mooring on floats, buoys, light boats, floating docks and floating docks. There are single claw anchors, spiral anchors and fungus anchors.

1. Basic structure and principle of ship The hydrofoil is the use of thrusters to push the ship forward, when the speed of the ship gradually increases, the buoyancy provided by the hydrofoil will lift the ship off the water, thus greatly reducing the water resistance to increase the sailing speed. 2. What is the basic structure and principle of the ship Answer: Marine Engineering Technology (shipbuilding, outfitting direction of professional courses include: Main courses: Engineering Mechanics, Ship Structure and Drawing, Ship Electrical Basics, Ship and ocean Engineering Materials, Ship principles, Ship welding technology, Ship Design Fundamentals, Ship CAD/CAM, Professional English, Shipbuilding Production Design, Ship Construction technology, Ship outfitting engineering Fundamentals, Ship inspection, etc. 3. Structure and working principle of the ship The principle of self-drainage is based on the "law of buoyancy" (or Archimedes' law). Any object in a liquid will be subjected to a buoyancy force equal to the weight of the liquid displaced by the object itself. An object sinks when its weight is greater than its buoyancy; If it is less than buoyancy, it will rise; When it is equal to the buoyancy, it will hover in the liquid, and the two forces are equal in magnitude, but in opposite directions. 4. Basic structure of the ship The general transport ship now consists of a deck department, including chefs and waiters, and an engine department; the earlier business department and radio service have been abolished. In addition to the chef and service staff, the deck department also includes all levels of sailors, first mate, second mate, third mate. The engine department includes all levels of mechanics, big pipe wheel, second pipe wheel, third pipe wheel, and motor staff 5. Basic structure and construction principle of the ship Good jobs. Marine and Marine Engineering in Ireland is the study of the working principles of Marine turbines. It mainly studies the knowledge of ship structure, navigation principle, safety design and construction regulations and norms of important classification societies at home and abroad, and studies ship design methods and how to ensure sailing speed, good maneuverability and wind and wave resistance. 6. Differences in basic structure and principles of ships The major of shipbuilding and ocean engineering belongs to the category of engineering discipline, and the major belongs to the category of ocean engineering. Professional code 081901. The major of Ship and Ocean Engineering aims to cultivate senior professionals with solid foundation of natural science and engineering technology, strong engineering practice and research ability training, master the basic knowledge of ship and ocean engineering, have high foreign language and computer application ability, and can be engaged in the design, construction, inspection and management in the field of ship and ocean engineering. 7. Ship design principles It should be the insulation monitoring principle. Including DC superimposed insulation monitoring method, S injection monitoring method, zero sequence current monitoring method and multi-frequency signal monitoring method. The principle is as follows The multi-frequency signal monitoring method is also called adaptive monitoring method. The monitor will configure the test signal according to the system voltage, capacity and other factors. Compared with the above three test methods, it has the advantages of sensitive monitoring, suitable for AC/DC hybrid system, and low interference to the system. 8. Ship basic structure drawing Rudder basic structure diagram A rudder is a device used to change or maintain the direction of a ship. Rudders can be divided into many kinds. According to the support of the rudder, it can be divided into multi-supported rudder, semi-suspended rudder, suspended rudder and double-supported rudder. According to the axis of the rudder rod, it can be divided into ordinary rudder, balanced rudder and semi-balanced rudder. According to the shape of the rudder section, it can be divided into flat rudder (the emergency rudder will be introduced in this article can be counted as a flat rudder), improved flat rudder, streamlined rudder and rectifier rudder. The working principle of a rudder is related to pressure. When the ship is sailing on the right rudder, the flow rate on both sides of the rudder blade is symmetrical and equal, and no rudder pressure is generated. When operating a certain rudder Angle, the two sides of the rudder blade will produce a pressure difference, and eventually guide the ship to turn. Of course, this paragraph is only a brief introduction, interested friends can search on their own. 9. Ship structure diagram The document structure of the ship safety management system can be composed of ship safety management manual, ship safety management professional manual or procedure, ship safety operation instructions and ship saf

The anchor is an indispensable equipment to ensure the safety of the ship, and the ship anchor mainly has the anchor crown. Composed of pin, anchor claw, anchor shank, anchor rod (also called cross bar or stabilizer bar) and anchor shackle. The way the anchor is cast Anchoring is a common anchorage method for ships. The process is roughly: the ship to the anchor chain or anchor cable connected anchor thrown into the water to land, and make it into the soil, the anchor produced by the gripping force and the bottom consolidated, the ship firmly tied in the predetermined position, according to different waters, meteorological conditions and operational requirements, the anchor throwing method is different, the commonly used way has the first anchor, tail anchor and head and tail anchor. 1. Anchor the bow Bow anchoring, there are two kinds of single anchor and double anchor. Under normal circumstances, only a single anchor can be tied to the ship, only when the wind and waves are particularly large and the anchorage is large and small. When the bow anchor, the hull is subjected to the least external forces such as wind, current and wave impact, so this way is the main way of anchoring, and also the main reason for the main anchor to be arranged in the bow. There is usually only one bow anchor on small boats and fishing boats. In addition, any ship is fitted with two main bow anchors on the bow. When the captain reaches a certain degree, the ship should also have a spare main anchor, also known as wind anchor. 2. Anchor astern The stern anchor is mostly used for river boats and landing boats. When river boats are moored downstream, they are often anchored at the stern to ensure safety and avoid turning around. In the operation of the landing ship retreating from the beach, with the cooperation of the main engine, relying on the tension of the anchor machine to pull the ship running on the beach. 3. Anchor head and tail If a ship is to be anchored always with its sides facing the wind, it is to be anchored head and tail. The method of head and tail anchoring is generally to throw the main anchor from the head wind direction, from the stern of the ship to the outer side of the main chain has been thrown, and then release some main chain can be, another method is to throw the main anchor from the tail after the first main anchor is thrown. The tail anchor is usually carried out and dropped by boat, and the tail anchor is generally smaller than the main anchor, about 1/3 of the main anchor. Types and characteristics of anchors There are many kinds of anchors, which are roughly divided into four types: rod anchor, rod anchor, large claw force anchor and special anchor, and more than ten kinds of anchors. 1. There is an anchor An anchor with a cross bar is a rod anchor. The characteristic of this kind of anchor is that an anchor claw is inserted into the soil, and when the anchor is dragged on the sea floor, the cross bar can prevent the anchor claw from tipping over and play a stable role. There are navy anchors, Lamen anchors, single-claw anchors and Japanese anchors. Navy anchor: The oldest typical pole anchor, also known as a common anchor. This kind of anchor has a large grip and can firmly grasp all kinds of soil, but it is inconvenient to rewind and put, and it is not used as the main anchor on modern large ships, but only on sailing ships and small inland river boats. Lamen anchor: A naval anchor with a swivelable jaw. In use, when one claw is in the ground, the other claw can be turned to the anchor handle and attached. This kind of anchor is more convenient to use than the navy anchor, but the holding force is smaller than the Navy anchor, and only one bolt is used to connect the anchor handle, and the safety is poor. Therefore, it can only be used in sailing ships and inland boats, and the anchor weight is generally not more than one ton. Single fluke anchor: Similar to naval anchors, with only one fluke, but larger in size. This type of anchor has more claw force than naval anchors. Positioning anchors for a variety of engineering ships, dredgers commonly use this anchor to ensure that the ship does not move during dredging operations. Japanese anchor: It is a kind of double-clawed anchor used on Japanese fishing boats, and the cross bar is fixed under the anchor crown, which not only maintains the advantages of large grip, but also is convenient to collect. 2. Rodless anchor There is no cross bar, and the two fluke anchor that the anchor fluke can turn is a rodless anchor. The characteristics of this kind of anchor are that two claws are simultaneously inserted into the soil during work, good stability, strong adaptability to various soil qualities, and convenient collection. Rodless anchors have developed rapidly, from the first generation to the third generation. Commonly used rodless anchors mainly include Hall anchors, Spaker anchors, AC-14 anchors and DA-1 anchors, as shown in Figur
