Problems solved by technology
However, the counter-rotating propulsion device requires two sets of rotating drive devices, and the rotation mechanism of the inner and outer shafts is usually used, and the inner and outer shaft drives consume more energy than the single-axis drive, and the noise of the propeller is relatively large; the counter-rotating propulsion device lacks protection Structure, easy to collide with foreign objects and damage, its service life is short

The invention relates to a torque self-balancing combination propeller of an underwater navigation body. The torque self-balancing combination propeller comprises a rotor placed between a stern section of the navigation body and a stern cap of the propeller. The rotor comprises a propeller hub and a paddle. The propeller further comprises guiding pipes which are arranged on the stern section of the navigation body, the rotor and the stern cap of the propeller in a sleeved mode. A front-arranged support is arranged on the outer wall of the stern section of the navigation body. A back-arranged guiding blade is arranged on the outer wall of the stern cap of the propeller. The outer end portion of the front-arranged support and the outer end portion of the back-arranged guiding blade are fixedly connected to the inner wall of the guiding pipe together. The torque self-balancing combination propeller has the advantages of being compact in structure, simple in driving mechanism, high in propulsive efficiency and low in noise, torque self balancing can be achieved, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of ship engineering, in particular to a propulsion device. Background technique [0002] The research on the propulsion device of underwater vehicles has always been the frontier and focus of propulsion device research. The development of high-propulsion-efficiency propellers can help improve the range and speed of underwater vehicles, and the application of low-noise propellers can enhance the concealment and survivability of underwater vehicles. [0003] Existing propulsion devices for underwater vehicles are generally propeller propellers or counter-rotating propeller propellers; conventional propeller propellers cannot fully recover the wake behind the propeller, so the propulsion efficiency generally does not exceed 70%, and the propeller is in operation. It will generate a torque opposite to the rotation direction of the propeller, which will affect the navigation attitude of the vehicle. In order t...
