Abstract

The invention relates to the technical field of ships, in particular to a propeller-hanging arm type counter-rotating device, a counter-rotating system and a ship. The technical problems in the priorart that a counter-rotating propeller is limited in power due to the limitation of a rudder ball, after the counter-rotating propeller rotates with a rudder, the efficiency is lowered, the installation and use of the counter-rotating propeller is severely restricted by a rudder blade, and a rudder stock needs to additionally bear a larger thrust of the counter-rotating propeller are solved. The propeller-hanging arm type counter-rotating device comprises a propeller-hanging arm and a counter-rotating propeller, wherein the counter-rotating propeller is installed between a propeller and the rudder blade and is independently arranged, and the propeller-hanging arm are separately connected with the counter-rotating propeller and a hull plate and can drive the counter-rotating propeller to move to adjust the position of the counter-rotating propeller. The maximum power of the ship is improved, the maximum diameter of the counter-rotating propeller is significantly improved, the propulsiveefficiency is ensured, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an oar arm type counter-rotation device, a counter-rotation system and a ship. Background technique [0002] Energy saving and environmental protection are the eternal theme of human beings, and the shipbuilding field is naturally inseparable from this topic. Improving propulsion efficiency and recovering surplus energy are effective energy-saving and environmental protection measures in ship technology. The counter-rotating propeller technology officially solves the problems of ship propulsion efficiency and recovery of surplus energy. The counter-rotating propeller can absorb the remaining energy in the wake vortex of the propeller and improve the propulsion efficiency of the propeller. There are many research results at home and abroad. However, the transformation and application of these research results have been limited, especially in medium and large merchant ships. How ...
