Marine energy-saving stator

Abstract

The invention discloses a marine energy-saving stator which comprises an X shaft, a propeller is arranged on the outer side of the X shaft, a paddle disc face is arranged on one side of the propeller, a movable block is arranged on one side of the paddle disc face, a movable hook is arranged on one side of the movable block, a first blade is arranged on one side of the movable hook, and a second blade is arranged on one side of the first blade. And a third blade is arranged on one side of the second blade. According to the marine energy-saving stator, the paddle efficiency can be improved within the full navigational speed range, the purposes of energy conservation and emission reduction are achieved, meanwhile, the vibration noise problem is solved, and through CFD simulation and ship model pool tests, the energy-saving effect is improved by 20%-80% compared with a traditional stator. When the three-blade scheme is used, the construction cost can be additionally saved, in order to improve the propelling efficiency and consider the line type of the tail of the ship body, the blades are arranged in front of the propeller, the blades are reasonably arranged in the rotating range of the whole propeller, and the blades are arranged in the first quadrant, the fourth quadrant and the third quadrant in front of the propeller disc face respectively.

Description

technical field [0001] The invention relates to the technical field related to ships, in particular to a marine energy-saving stator. Background technique [0002] In the shipping industry, fuel cost is one of the main operating costs. Energy conservation and environmental protection, as a topic of common concern in the shipping industry, is becoming more and more important in the context of EEDI. Install energy-saving stators at the tail of the hull and in front of the propeller to improve the matching of propellers and improve propulsion. Efficiency, to achieve the purpose of energy saving and emission reduction, but the existing device only considers that the stator is on the upper left or left side of the flow field in front of the propeller, and only changes the local flow field, which has problems such as low efficiency. [0003] However, the energy-saving stator currently used, in order to improve the propulsion efficiency, considers the shape of the tail of the hull....
