Problems solved by technology

However, nowadays, the sliding elastic structure is generally used to change the diameter of the blade, which has a large reset error and a large transmission torque error, and the rotation balance of the propeller is poor, which weakens the response speed of the water flow and reduces the maneuverability of the ship.

Embodiment Construction

[0034] The present invention will be described below in combination with specific embodiments and with reference to the accompanying drawings.

[0035] First embodiment of marine propulsion device

[0036] Such as figure 1 As shown, the marine propulsion device 100 includes a propeller 101 , a first ducted barrel 102 and a second ducted barrel 103 . The first duct tube 102 and the second duct tube 103 are arranged coaxially with the rotation axis of the propeller 101 , and both are arranged in the outflow direction 01 of the propeller 101 . The diameter of the first ducting cylinder 102 is larger than the diameter of the second ducting cylinder 103 . The first ducting cylinder 102 is located outside the second ducting cylinder 103 . A trumpet-shaped lip 1021 is provided at the entrance of the first duct 102 . When the first working position 104 of the dancing angle control mechanism, the blade of the driving propeller 101 is positioned at the first working position 104, an...

Abstract

The invention provides a propelling device used for a ship. A propeller is provided with a propeller shaft, propeller hubs and propeller blades; a driving device drives the propeller to rotate; the propeller blades are installed on the propeller hubs through flapping hinges respectively; a flapping angle control mechanism is movably connected with the propeller blades and drives the propeller blades to rotate around hinge shafts of the flapping hinges. At least part of propeller blades are immersed in water. The working efficiency of the propelling device used for the ship is improved.

Description

technical field [0001] The invention relates to the field of ships, in particular to a ship propulsion device, a ship with the propulsion device, and a driving control method for the ship. Background technique [0002] Propellers are divided into two categories: fixed pitch and variable pitch. The blade installation angle suitable for low speed is difficult to adapt to high speed, and conversely, the installation angle suitable for high speed is difficult to adapt to low speed. So the fixed pitch propeller can only be efficient in the selected speed range. In order to solve this contradiction, a variable-pitch propeller has appeared, that is, the pitch of the propeller is changed through a control device. The variable torque propeller changes the output torque by changing the inclination angle of each blade of the propeller, that is, the thrust of the propeller can be changed under the condition of constant speed. The use of variable torque propellers greatly improves the...
