It is a component with an inverted "L" shape. It has two types: fixed type and movable type. The fixed type is the anchor of the steel cable guide pulley of the deep-sea winch. In addition to the fulcrum, the movable type also uses the hydraulic cylinder or other mechanical devices to pour the ocean survey instruments and equipment out of the ship or flip them into the ship for collecting plankton collection nets. There is a steel top pole with a certain span and a relatively high height. It is used to collect and release hydrographic instruments. The steel bracket with a certain span and height is installed on both sides of the ship. It is a small platform for investigators to conduct marine surveys or auxiliary operations. It refers to an anchor specially used for ships to stop and moor in ice areas. It is generally a rodless single-bar anchor. It is a special device to ensure the operation of benthic trawling.
