Abstract

The invention discloses a jellyfish-like underwater propulsion device. The propulsion device simulates the opening and closing movement process of a canopy of the jellyfish based on the bionics principle; a servo motor is controlled to rotate forward and rotate reversely so as to drive a nut to correspondingly move back and forth along a guide rod under the drive of a feed screw; when the nut moves forward, a supporting rod mounted on a nut groove drives a flexible web contract under the effect of the hydrodynamic force, and the device suffers small resistance; and when the nut moves backward, the supporting rod mounted in the nut groove drives the flexible web to unfold under the effect of the hydrodynamic force, and a great thrust is generated to propel the device to sail forward. The jellyfish-like underwater propulsion device is simple in structure, low in cost and good in explosive force. The propulsion device is mounted on the existing underwater vehicle to effectively improve the maneuvering performance of the underwater vehicle in low-speed sailing.

Description

technical field [0001] The invention relates to a propulsion device for an underwater vehicle, in particular to a jellyfish-like underwater propulsion device. It belongs to the field of shipbuilding industry and is suitable for underwater vehicles and small and medium-sized ships with high maneuverability and low noise in low-speed navigation. Background technique [0002] The propulsion device of an underwater vehicle is the main factor affecting the maneuverability of the vehicle itself. At present, most underwater vehicles at home and abroad use electromagnetic motors or hydraulic motors as the propeller propulsion device of the prime mover. Propeller propulsion devices have been widely used in the shipbuilding industry, but they still have disadvantages such as large disturbance to the environment, high noise, and poor maneuverability; There are many disadvantages in the use of propeller propulsion devices, especially in the case of low-speed navigation, propeller prop...
