Ship propeller

Abstract

The invention provides a ship propeller which comprises an annular guide rail, a mounting base, a propelling assembly, a telescopic supporting mechanism, floating and swinging mechanisms and a steel cable, the mounting base is mounted on the outer circle face of the annular guide rail in a matched mode, the mounting base is driven by a driving assembly to move along the outer circle face of the annular guide rail, and the propelling assembly is arranged on the mounting base; the telescopic supporting mechanism comprises a linear guide rail, a sliding block, a connecting rod and a top plate, the two floating and swinging mechanisms are oppositely arranged, and each floating and swinging mechanism comprises a connecting base, a swing arm, a floating plate and a winding wheel. The floating plates float on the water surface, the floating plates can drive the swing arms to swing when the ship is in different draft states, the swinging swing arms drive the sliding blocks to move through the steel cable, the two floating and swinging mechanisms drive the two sliding blocks to move in the opposite directions respectively, thus the top plate ascends and descends, and the height of the whole annular guide rail is automatically adjusted according to the ship draft, and thus the propelling assembly can obtain higher propelling force.

Description

technical field [0001] The invention relates to the technical field of ship accessories, in particular to a ship propeller. Background technique [0002] When the draft of the hull is deep and the propeller sinks into the water, the thrust obtained by the propeller will be reduced because the velocity of the water surface is greater than that of the underwater, and the main engine will be "lightly loaded", so it is necessary to adjust the height of the propeller to adapt to different Draft. [0003] What is disclosed as CN109018283B is a ship propeller, a bottom plate, a propulsion mechanism, an underwater gear box, a slewing mechanism, a telescopic mechanism and a control system. Place the hole, one end of the hollow rotating shaft located on the bottom plate of the ship is connected to the propulsion motor through a spline shaft and a linkage in turn, and the other end is connected to the gear of the underwater gearbox, and the underwater gearbox is installed There is a ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art uses the pressure sensor to detect the draft, and the active driving parts are required to adjust the height during the adjustment process, and the bottom of the water surges under the action of the propeller, so the signal sensor cannot accurately measure the bottom of the water. pressure, which in turn causes the thrusters to fail to match the draft
