Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0036] Such as figure 1 As shown, the propulsion device based on the embodiment of the present invention is a double counter-rotating propulsion device that generates propulsion while the two propellers 20, 30 rotate in opposite directions. Here, the propulsion device rotates the two propellers 20 , 30 in opposite directions relative to each other according to the rotation of the second drive shaft 10 a penetrating through the stern 3 of the hull 1 and provided in a direction perpendicular to the first drive shaft 10 . At this time, the ship body 1 is provided with a drive source 140 (motor, generator, engine, etc.) that rotates the second drive shaft 10 a. Such a propulsion device may include a diverter 150 in the hull 1 so as to change the propulsive force applied to the hull 1 by the front propeller 30 and the rear propeller 20 in all directio...

Abstract

Disclosed are a propulsion device for a ship and a ship having same. The propulsion device, according to an embodiment of the present invention, comprises: a rear propeller fixed to a first driveshaft; a front propeller positioned in front of the rear propeller and supported rotably on the first driveshaft; a counter rotation device, which penetrates the hull, and which counter-rotates the front propeller and the rear propeller on the basis of the rotation of a second driveshaft, which is installed perpendicular to the first driveshaft; and a housing installed so as to envelope the second driveshaft and the counter rotation device.

Description

technical field [0001] The invention relates to a ship propulsion device and a ship including the device, in more detail to a ship propulsion device in which two propellers rotate in opposite directions to generate propulsion and a ship including the device. Background technique [0002] A ship is equipped with a propulsion device that generates propulsion for navigation. Typically one propeller is used for propulsion. However, since the propulsion device provided with one propeller cannot use the rotational kinetic energy of the water flow as propulsion force, the kinetic energy loss is large. [0003] Counter Rotating Propeller (CRP; Counter Rotating Propeller) is a device that recovers this lost rotational kinetic energy into propulsion. The double counter-rotating propulsion device generates propulsion while two propellers arranged on the same axis rotate oppositely to each other. In the counter-rotating propulsion device, the rear propeller rotates in the opposite di...
