Soft seabed mud spiral propulsion vehicle and traveling method thereof

Abstract

The invention discloses a soft seabed mud spiral propulsion vehicle and a traveling method thereof. A novel propulsion device capable of traveling in soft seabed mud is required. According to the invention, four spiral propellers are arranged at the left front, right front, left rear and right rear positions of the bottom of a frame; the spiral propellers comprise spiral blades, propeller shells, motors, planetary reducers and shaft sealing elements; one end of each propeller shell and a supporting shaft fixed on the end face of a motor seat form a revolute pair, the other end of the propeller shell and a motor output shaft form a revolute pair, and the supporting shaft is fixed with the frame; the propeller shells are driven by the motors; a generator supplies power to the motors by umbilical cables; a control cabinet transmits a control signal to the motors by virtue of the umbilical cables; the spiral blades are fixed outside the propeller shells; the shaft sealing elements are arranged between the supporting shaft fixed on the end face of the motor seat and the frame and between the motor output shaft and the frame. The vehicle disclosed by the invention is capable of overcoming widely distributed seabed mud resistance, freely moving forwards, retreating, steering, and transversely traveling to the left and the right.

Description

technical field [0001] The invention belongs to the field of marine engineering and underwater engineering, and in particular relates to a seabed ooze screw propulsion underwater vehicle device and a traveling method thereof. Background technique [0002] With the development of marine engineering and offshore engineering, many underwater operations require vehicles that can walk on the seabed to complete. There is a deep layer of soft mud distributed on the surface of the seabed, and wheeled vehicles and tracked vehicles will suffer serious subsidence when traveling in the seabed soft mud, which will cause the track and wheels to lose their propulsion. Therefore, a new propulsion device is needed to overcome engineering difficulties. [0003] After searching the existing technical documents, it is found that the Chinese patent No. 201510450587.0 (patent name: a screw propulsion paddy field walking machine) provides a vehicle device for walking in paddy fields, but the driv...
