Description

Lifting and steering integrated structure of marine top flow machine and marine top flow machine Technical Field The invention relates to the technical field of marine equipment, in particular to a lifting and steering integrated structure of a marine top flow machine and the marine top flow machine. Background In order to keep the fixed point of the ship, the marine top flow machine needs to adjust the underwater propeller to a proper depth and direction. In the conventional adjustment mode, the lifting action is usually realized through linear transmission of a rope type structure, and the horizontal steering is dependent on an additional rotary driving system. The two systems are usually completely decoupled mechanically, not only require independent driving motors and control systems, but also often interfere with each other in space layout, and are relatively inconvenient to install and maintain. Especially on small and medium-sized ships, the space and the load capacity are limited, and the split and redundant structure becomes a remarkable disadvantage. Still further, conventional so-called "integrated" attempts have tended to simply pack two separate motors compactly within a housing, without fundamental fusion from the drive principle. This physical proximity does not reduce the number of power sources and the complexity of the control unit, nor does it address the interference problems that may exist in the dynamics of the two sets of movements. Meanwhile, the mechanical interface between the rope type lifting structure and the rotary driving structure often has contradiction between structural strength and motion precision.
