The scientific investigation ship is the first choice for ocean field investigation as a movable laboratory and can carry advanced investigation equipment in a land laboratory. Compared with a land laboratory, the scientific investigation ship has a severe working environment, and the lifting fin plate system is suitable for installation and normal use of precision instruments in the environment. The lifting fin plate is mainly used for installing scientific experimental instruments capable of performing submarine detection and the like at the bottom of the fin plate, and the main state of the lifting fin plate is divided into (1) a cruising state in which the instrument at the bottom of the lifting fin plate performs detection activities underwater; (2) after the scientific detecting instrument at the bottom of the lifting fin finishes detecting, the lifting fin needs to be lifted so as to be convenient for replacing the scientific detecting instrument at the bottom of the fin, and the process is in a lifting state; (3) this state is the maintenance state when the scientific instrumentation of the elevating fin does not perform any tests or requires maintenance on the elevating fin.
