Bionic underwater vehicle flapping wing propulsion device

Abstract

The invention discloses a bionic underwater vehicle flapping wing propulsion device. An underwater vehicle comprises a drive motor assembly, a transmission gear set, a ball screw, a steering engine, asteering shaft, an adaptive under-actuated flexible wing framework, a single-sliding block and double-rocker mechanism, and a fixing seat, the drive motor assembly, the ball screw and the fixing seatare connected with an underwater vehicle body separately, the drive motor assembly is composed of a motor, a speed reducer and an encoder, the ball screw is composed of a screw rod, a screw nut and ascrew fixing seat, and an output shaft of the speed reducer is connected with a driving gear of the transmission gear set; a driven gear of the transmission gear set is connected with the screw rod of the ball screw, and the motor drives the screw rod to rotate through the transmission gear set. The bionic underwater vehicle flapping wing propulsion device has the advantages that the integral structure is provided with a front end swing and a rear end swing, the whole device has two degrees of freedom, and propulsion, turning, floating, submergence and other movements of the underwater vehicle can be achieved.

Description

technical field [0001] The invention relates to a propulsion device for an underwater vehicle, more specifically, to a flapping-wing propulsion device for a bionic underwater vehicle. Background technique [0002] In recent years, with the continuous deepening of human exploration of the ocean, underwater vehicles have played an increasingly important role. This makes us have higher requirements for the performance of underwater vehicles in all aspects. At present, most underwater vehicles use propeller propulsion. Due to low propulsion efficiency, high noise, and insufficient flexibility at low speeds, traditional propulsion methods are increasingly difficult to meet the diverse tasks of underwater vehicles. Require. Sea turtles, manta rays and other marine organisms have evolved through countless years of flapping wing movement, which has the advantages of high propulsion efficiency, strong stability, maneuverability and maneuverability, and is especially suitable for pr...

Problems solved by technology

The first is to use the form of fins and skins, and use the motor to control the rotation of the fins. Since the fins on one side of the wing are generally not less than three, multiple sets of motors are required, which increases the control of the wing. The development of the system is difficult, and at the same time, the adaptability to the environment is not strong; the second is the driving method that uses a combination of mechanisms such as cranks and rockers. Imitating the actual flapping movement of marine life, the movement efficiency has not been greatly improved
