Ship model gravity center measuring device

The invention belongs to the field of measuring equipment, and particularly relates to a ship model gravity center measuring device. The ship model gravity center measuring device mainly comprises a model placing platform, a telescopic bracket and a bubble type level meter. Four digital displaying type pressure gauges are arranged between the bracket and the platform. The pressure gauges can freely move along the long side of the platform through the guide rail according to the measuring requirement. The side surface of the platform is provided with scales through which a slide rail distance and a slide rail moving distance can be read. According to the ship model gravity center measuring device, a moment balance principle is utilized; through reading the indicating numbers of the different pressure gauges and the distances therebetween, the gravity center position of the ship model is measured and calculated according to a moment balance torque; thereby satisfying requirements for high accuracy and high spee
