The invention discloses an intelligent adjusting and controlling system for lifting and steering of a wave power generation platform. The intelligent adjusting and controlling system comprises a sensor module, a controller module, a driver module and an actuating module. The sensor module comprises ultrasonic sensors, a gyroscope used for collecting device posture information, and a wave buoy used for collecting the sea surface wave direction. The controller module comprises an MCU. The driver module is used for transmitting a control command to the actuating mechanism. The actuating mechanism comprises a lifting coarse adjustment branch, a lifting fine adjustment branch and a motor branch. According to the intelligent adjusting and controlling system, lifting and steering are integrated into a closed-loop system, and self-adaption lifting and steering actions of a device are achieved; and by feeding back data analysis results of ultrasonic waves and the gyroscope, monitoring to the real-time state of the device is achieved. The reliability and the adaptability of a current wave power generation device are greatly improved, damage caused by wave impact to a frame of the device is reduced, and energy consumed by lifting and steering is reduced; and the effective utilization rate of wave energy is increased.
