Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] A high-efficiency sailing propeller, comprising a hull 1, a first engine 2 and a second engine 3 are installed inside the stern of the hull 1, the output shaft of the first engine 2 is connected to a first propeller shaft 5 through a first torque booster 4, The first torque booster 4 is used to increase the transmission torque to ensure that the first propeller rod 5 is stably rotated under the drive of the first engine 2, and the end of the first propel...

Abstract

The invention discloses an efficient sailing propeller and a force application pushing method. The propeller comprises a hull; a first engine and a second engine are installed in the stern of the hull; a first propeller rod and a first torque amplifier are obliquely installed; a second propeller rod and a second torque amplifier are obliquely installed; and the included angle formed between the first propeller rod and the horizontal line of the hull and the included angle formed between the second propeller rod and the horizontal line of the hull are both theta. The method comprises the following steps that: the mounting and fixing modes of the first propeller rod and second propeller rod are changed, first propeller blades deviate from the horizontal line of the hull by 3 degrees; secondpropeller blades deviate from the horizontal line of the hull by 3 degrees; the first engine drives the first propeller rod and the first propeller blades to rotate; and the second engine drives the second propeller rod and the second propeller blades to rotate. Under the condition that engine power and extra power consumption are not increased, power pushing can be changed, so that sailing speedis effectively increased, and meanwhile, an energy-saving effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a propeller for high-efficiency navigation and a force-applying propulsion method. Background technique [0002] Generally, the position of the engine compartment of a general ship is provided with two propellers to drive in parallel with the water surface of the ship (such as image 3 ), the installation position of the propeller in the existing ship technology is set parallel to the horizontal plane of the ship. The propeller rotation mode of the ship is usually that one end of the propeller rotates clockwise and the other end counterclockwise in the water to drive power. It will shift to the middle, and the direction of water flow will also flow to the middle to generate resistance. Since the size of the ship needs to meet the national standard range, and the space of the ship's engine compartment and the distance between the propellers in the ship are limited, the size of the p...
