Apparatus for real-time detection of balance of self-elevating platform and driving depth of pile leg

The utility model provides an apparatus for real-time detection of the balance of a self-elevating platform and the driving depth of a pile leg. The apparatus comprises a multi-tooth sensor mounted in a gearshaft assembly of a rack-and-pinion elevating system of the pile leg of the platform; a supersonic wave water depth sensor mounted on the bottom of a hull of the platform, leveling to the bottom of a ship; a supersonic wave air gap sensor mounted on a fence in the external periphery of a helicopter platform; a double shaft inclination angle sensor directly mounted on a fixed surface of an ocean platform to measure the change of the inclination angle of the platform; a dynamic data acquisition terminal special for the platform connected with each sensor (in a wired or wireless manner) and used for receiving signals and transmitting the signals through a ZigBee wireless ad hoc network; a center acquisition terminal used for receiving wireless transmission signals and transmitting the signals to a database se
