The invention relates to the technical field of underwater vehicle propulsion, in particular to a multi-section pulse underwater propulsion device. Comprising a first valve assembly, an expansion assembly and a second valve assembly which communicate with one another, the expansion assembly comprises an expansion pipe and an expansion rubber pipe, and the expansion pipe is connected with a first ventilation pipeline; the first valve assembly comprises a first valve pipe and a first valve rubber pipe, and the first valve pipe is connected with a second ventilation pipeline; the second valve assembly comprises a second valve pipe and a second valve rubber pipe, and the second valve pipe is connected with a third ventilation pipeline; the direction of pulse thrust is adjusted by adjusting the ventilation sequence of the first ventilation pipeline, the second ventilation pipeline and the third ventilation pipeline, the contraction and expansion amplitude of the expansion rubber pipe is adjusted by controlling the pressure intensity of ventilation and air exhaust, so that the gas flow is controlled, the injection thrust is adjusted, the gas flow speed of ventilation and air exhaust is controlled, and the injection duration is adjusted. The requirements of different working conditions such as low-speed cruising or high-speed sprint can be dynamically met, and the adaptability is higher.
