Abstract

The invention provides a modularized water-jet propulsion steering reversing mechanism, which relates to the technical field of ship propulsion, and includes a steering reversing mechanism bracket for fixing the water-jet propulsion steering reversing mechanism; It is connected to the support of the navigation mechanism, and is used to move left and right around the first pin shaft under the drive of a steering cylinder built in the rudder, so that the jet water flow is reversed to the side to realize steering; the reversing door is connected to the rudder through a second pin shaft, It is used to realize the forward steering function when it is in the open state, and to make the jet water flow reverse to the bottom of the ship to achieve reverse sailing when it is in the closed state; the auxiliary rudder plate is installed on the rudder through fasteners, and is used to rotate together with the rudder to lift the rudder effect. The invention reduces the number of specifications of the steering and reversing mechanism through water jet propulsion, reduces design and processing costs, and shortens the processing cycle; effectively reduces the difficulty of assembly and disassembly; reduces the processing difficulty and scrap rate of guide vanes ; Improved product reliability.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to a modularized water jet propulsion steering reversing mechanism. Background technique [0002] Water-jet propulsion is an important ship propulsion technology. The reaction force of the high-speed water flow ejected by the propulsion pump in the water-jet propulsion device is used to push the water carrier forward, and the carrier is manipulated by distributing and changing the direction of the jet flow through the steering reversing mechanism. Compared with traditional propulsion methods, water jet propulsion has the advantages of excellent maneuverability, strong cavitation resistance, high propulsion efficiency, simple transmission shafting, low vibration and environmental protection, so it is widely used in high-performance ships. [0003] The existing small and medium power water jet propulsion steering and reversing mechanism mainly includes a rudder and a reversing...
