Abstract

The invention provides a high-mobility ship propelling mechanism. The high-mobility ship propelling mechanism comprises an airscrew propeller and a hull internal power supply device, wherein the screwpropeller is installed on a side wall of a hull, and comprises a propeller housing, a propeller connecting device, a fixing device, a sealing cabin, a fairing, a sealing door, a motor fixing housing,a motor and an airscrew; and the hull internal power supply device is installed in the hull, and comprises a switch control device, a generator, a main power distribution module, a ship electric appliance, a frequency converter, a battery converter and a battery. The high-mobility ship propelling mechanism is capable of realizing in-situ rotation, greatly reducing a turning radius of a ship, thereby improving mobility of the ship, and because the propelling device is positioned at two sides of the ship, a horizontal direction force moment is increased, and ship stability in a turning processof the ship is improved, and because the airscrew propeller is installed at the outer side of the hull, a hull internal structure is not changed, so the high-mobility ship propelling mechanism is beneficial to upgrading and rebuilding of an old-type hull.

Description

technical field

[0001] The invention relates to the technical field of ships, in particular to a ship propulsion mechanism. Background technique

[0002] At present, most ship power propulsion systems connect the diesel engine gearbox and the ship propeller directly with the shaft system. This transmission method has the characteristics of good maneuverability and convenient layout. Due to the existence of the shaft system, the propulsion device is usually installed at the rear of the ship. . With the advancement of technology, the current electric propulsion system is becoming more and more perfect. Compared with the traditional ship power system, the electric propulsion system has a wide range of speed regulation, large driving force, easy forward and reverse, small size, flexible layout, convenient installation, and easy installation. Maintenance, low vibration and noise.

[0003] As a new type of propulsion system for ships, electric propulsion is being studied in dept...
