Problems solved by technology
[0003] Conventional azimuth thrusters are only equipped with fixed-pitch propellers, and the thrust of the ship is adjusted by changing the speed of the main engine. The thrust below the idle speed of the main engine is rarely used, and the main engine cannot be attached to other equipment.

The invention relates to a marine adjustable-pitch all-direction blade pitch feedback mechanism. The mechanism is characterized in that the feedback mechanism using an inner oil pipe of a propeller shaft as a sample point comprises a slider, horizontal links, L-shaped vertical links, a support, a feedback rod, guide rods, a feedback spring, a feedback board mounting base, a feedback board, a universal ball, a pitch feedback rod and a pitch pointer. The slider is connected to the inner oil pipe of the propeller shaft through a ball bearing. The feedback board mounting base and the support are fixedly mounted on a steering column. An intersection fulcrum of two linear segments of the L-shaped vertical links locates on the support. The feedback board mounting base is provided with a limit post and the guide rod. The feedback board is located on the feedback board mounting base. The feedback spring locates on the limit post between the feedback board and the feedback board mounting base. The feedback rod is fixedly connected with the feedback board. The feedback board is fixedly connected with one end of the pitch feedback rod through the universal ball. A pitch sensor is driven on the pitch feedback rod.
Description
technical field [0001] The invention relates to a pitch feedback mechanism with adjustable pitch full rotation, in particular to a pitch feedback mechanism which can be installed in variable pitch full rotation and used for accurate control and feedback of underwater blades. Background technique [0002] Adjustable pitch full rotation is widely used in port tugboats, fire boats, work boats (crane ships, scientific research ships, open-body mud barges, etc.), ferries and many other fields. It is a ship propeller with many parts and complex mechanisms. At present, only some foreign manufacturers can produce it. The built-in pitch feedback mechanism is the core component of this type of propeller, and its performance directly affects the performance of the propeller. The pitch feedback mechanism with adjustable pitch and full rotation requires flexible action, accurate feedback, and mutual movement without interfering with each other. According to the full rotation equipped wi...
