Abstract
A driving method is implemented to a lifting device of an underwater survey system, and the lifting device includes a phase-change heat exchange module, an oil bag module, a pressurized energy storage module, and a drive energy storage module. The driving method includes: controlling the pressurized energy storage module to extract hydraulic oil in the oil bag module to descend the lifting device; during a transformation of a phase-change material, the pressurized energy storage module transmitting hydraulic oil to the phase-change heat exchange module; transmitting the hydraulic oil inside the oil bag module to the pressurized energy storage module to descend the lifting device; controlling the drive energy storage module to transmit hydraulic oil to the oil bag module for rising the lifting device; and during a transformation of the phase-change material, transmitting the hydraulic oil in the phase-change heat exchange module to the drive energy storage module.
