Description

Technical Field

[0001] The utility model relates to the technical field of marine propellers, in particular to a telescopic lateral propeller. Background Art

[0002] Lateral thrusters are propulsion devices used on ships, submarines and other underwater or water vehicles. They are usually installed on the side of the hull and are used to control the lateral movement of the vessel in the water, that is, movement in the left and right direction. This is very useful for mooring, docking, navigating narrow waterways and maneuvering.

[0003] In traditional lateral thrusters, general marine lateral thrusters are fixed on the side panels of the ship, which requires the propeller to meet the requirement that the centerline of the blade must be located below the waterline. However, due to the complex conditions of the waters when the ship is docked, the position of the centerline of the blade below the light-load waterline is shallow, which directly affects the propulsion performance of the lateral thruster. In some small yachts, engineering vessels, etc., due to limited installation space, if traditional lateral thrusters are used, the position of the centerline of the blade below the waterline cannot be adjusted, which will also reduce the efficiency of power use. Especially in the case of insufficient draft depth, it often cannot meet the thrust required for hull maneuvering. In addition, since the traditional lateral thruster is fixed on the ship and cannot be adjusted in angle, it is not conducive to rapid docking in some narrow ports, and it is easy to collide with the port frequently when docking before it can stop steadily.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
