Unmanned ship gravity center adjusting device and unmanned ship

The invention relates to the technical field of underwater surveying and mapping devices, and provides an unmanned ship gravity center adjusting device and an unmanned ship. The mounting plate is horizontally mounted in an unmanned ship body, a battery mounting groove is formed in the mounting plate, and a sliding mechanism is arranged at the bottom of the battery mounting groove; the battery assembly is connected with a sliding piece in the sliding mechanism and used for sliding in the battery installation groove in the axis direction of the ship body. A battery assembly used for supplying power to the unmanned ship serves as a counterweight assembly for adjusting the gravity center of the ship body, and when the unmanned ship is additionally loaded, the battery assembly slides in the axis direction of the ship body and is matched with external monitoring equipment to determine the most appropriate gravity center position till the posture of the ship body meets the parameter requirements of the hanging equip
