Description

Technical Field

[0001] The present invention belongs to the technical field of propellers, and more specifically, relates to a U-shaped telescopic full-rotation propeller. Background Art

[0002] With the rapid development of marine ship technology, modern marine ships have become more and more capable, with wider working areas and larger draft depths, and many marine engineering ships have begun to widely use dynamic positioning systems. The ship dynamic positioning system consists of high-power thrusters, control systems, and sensor measurement systems. The dynamic positioning system continuously detects the deviation between the actual position of the ship and the target position, and comprehensively considers external environmental factors such as wind, waves, and currents, accurately calculates the size and direction of the thrust required to maintain the ship in a predetermined position or a specified navigation route, and automatically controls the propulsion direction and propulsion of each thruster on the ship to meet the positioning requirements of marine engineering ship operations.

[0003] Based on the above working characteristics, many ships need to be installed with multiple retractable full-rotation auxiliary thrusters, which can drive the ship to a safe area when the ship is in an emergency situation, or provide auxiliary propulsion power when the main thruster is insufficient and may cause the geophysical cable to be entangled.

[0004] Conventional telescopic full-rotation thruster motors are mostly installed vertically upward, which results in the overall height of the thruster being too large, causing a great impact on ships with a shallow draft, making it impossible to use the thruster on ships with a shallow draft.
