A combined ship rudder blade

Abstract

The invention provides a combined type rudder blade for a ship, and relates to the field of ships. The combined type rudder blade for the ship comprises a rudder blade body, the left side of the rudder blade body is movably connected with a ship hull through a plug shaft, a first cavity is arranged inside the rudder blade body, a second cavity is arranged inside the rudder blade body and located at the bottom of the first cavity, a clapboard is arranged on the top of the second cavity and located at the bottom of the first cavity, and a motor base is arranged at the bottom of the first cavity and located at the top end of the clapboard. According to the combined type rudder blade for the ship, the motor arranged inside the first cavity drives a rotating shaft to rotate, so that a moving sleeve connected with the surface of the rotating shaft in a sleeving mode drives a moving rudder blade to move; and when the moving rudder blade moves downwards, the contact face of the rudder blade body and water is increased, when the ship needs to steer urgently, the steering torque of the rudder blade body is improved, so that power consumption of a steering engine is not greatly increased, and the efficiency of steering is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a combined rudder blade for ships. Background technique [0002] The rudder blade is the body that produces the rudder force and is made of wood or steel. Now, except for wooden sailboats, they are all made of steel, and most of them are welded into hollow airfoils. The panel of the rudder blade is called the rudder plate. The rudder blade is used to change the direction of the ship during navigation. At present, most ships are built with rudder blades with a fixed size and cannot be changed. When the ship needs to turn sharply, the steering torque required by the rudder blades will increase rapidly, which will greatly increase the power consumption of the steering gear and easily cause damage to the steering gear.

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a combined rudder blade for ships, which solves the above-mentioned problem that most of the rudder blades for ships are fixed in size when they are built and cannot be changed. When the ship needs to turn sharply, the rudder blade The required steering torque increases rapidly, which greatly increases the power consumption of the steering gear and easily causes damage to the steering gear
