Vibration detection and conduction device for ship propeller shaft

The invention discloses a vibration detection and conduction device for a ship propeller shaft. The vibration detection and conduction device comprises a magnetic base, a support, an elastic supporting mechanism and a vibration conduction mechanism, the magnetic base is used for being attracted to a cabin bottom plate of a ship through magnetic force; the bottom end of the support is fixedly connected to the top of the magnetic base. an elastic supporting mechanism is mounted at the top end; the elastic supporting mechanism is arranged in the horizontal direction, one end of the elastic supporting mechanism is movably installed at the top end of the support, and the other end is fixedly provided with the vibration conduction mechanism used for guaranteeing that the vibration conduction mechanism makes contact with the propeller shaft all the time through elastic force; the vibration conduction mechanism is in rolling fit with the propeller shaft and used for conducting vibration of the propeller shaft.
