Abstract

The invention discloses a steering device for a water-jet propulsor, and belongs to the technical field of water-jet propulsion. The steering device comprises a steering nozzle and a steering drive mechanism, wherein the steering drive mechanism comprises a steering handle and drive assemblies; the steering handle comprises a first connecting part and a second connecting part; one end of the second connecting part is connected with the middle of the first connecting part, and the other end of the second connecting part is fixedly connected with the water outlet end of the steering nozzle; the middle of the first connecting part and the steering nozzle are coaxially hinged to the water outlet end of a guide vane nozzle; the steering drive mechanism comprises two drive assemblies; each drive assembly comprises cylinders and connecting rods; one end of each of the two connecting rods is connected with the corresponding cylinder, and the other end of each of the two connecting rods is connected with both ends of the first connecting part, so that the cylinders can be controlled to stretch out and draw back; both ends of the first connecting part are pushed and pulled by the corresponding connecting rod, so that the steering handle is rotated, and the steering nozzle is rotated by the rotation of the steering handle; the orientation of the steering nozzle is changed, so that the water current jet direction is changed and the steering of a ship is achieved.

Description

technical field [0001] The invention relates to the technical field of water jet propulsion, in particular to a steering device of a water jet propulsion device. Background technique [0002] The water jet propeller is a kind of ship propeller, which drives the ship through the reaction force generated by the jet water flow, and changes the jet direction of the water flow through the steering device to realize the steering of the ship. [0003] The steering device of a waterjet usually includes a cylinder, a steering shaft and a steering nozzle. Wherein, the steering shaft is installed in the through hole and the guide sleeve of the water jet inlet pipe transom, and the guide sleeve is installed on the outer wall of the water jet guide vane nozzle through a bracket and is the same as the through hole of the inlet pipe transom. One end of the steering shaft is connected to the oil cylinder, and the other end of the steering shaft is connected to the steering nozzle through a...
