Marine propulsion and anti-rolling device and ship

Abstract

The invention discloses a propelling and stabilizing device for a ship as well as the ship. The propelling and stabilizing device for the ship comprises a rotary propeller, a cylindrical rotating body, a first rotor / stator, a second rotor / stator, an energization change-over switch and a rotating device, wherein the energization change-over switch connects a power supply circuit of the second rotor / stator in a ship advancing process, so that the second rotor / stator is taken as a stator to generate a magnetic field, the first rotor / stator is taken as a rotor to drive the rotary propeller to rotate, and a ship body is pushed to advance; the energization change-over switch connects a power supply circuit of the first rotor / stator in a stop-ship work period, accordingly, the first rotor / stator is taken as the stator to generate the magnetic field, the second rotor / stator is taken as the rotor to drive the cylindrical rotation body to rotate, and the ship body is prevented from shaking; the rotating device is used for changing the direction of the cylindrical rotating body. A propelling device and stabilizing equipment are integrated, so that the problems that large ship body space is occupied by equipment, the operation is complicated and the like due to separate installation of the propelling device and the stabilizing equipment are solved, and the propelling and stabilizing device is suitable for being popularized and applied to a small ship or an unmanned surface vessel.

Description

Technical field [0001] The invention belongs to the technical field of ships, and specifically relates to a propulsion device and anti-rolling device applied to a small ship or an unmanned surface detection ship. Background technique [0002] Propulsion technology and anti-rolling technology are the two key technologies of ships. At present, marine propulsion methods mainly include rudder propeller propulsion, full-rotation electric propulsion, and water jet propulsion. Anti-rolling methods mainly use anti-rolling tanks and fin stabilizers. For most ships at present, rudder propellers are usually installed at the stern of the ship to provide thrust for the ship to propel the hull forward; at the same time, a anti-rolling device is installed at the bow of the ship to reduce the shaking of the hull in the water and satisfy The stability of the ship is required. However, this traditional design method, because the propulsion device and the anti-rolling device are designed separatel...

Problems solved by technology

However, in this traditional design method, since the propulsion device and the anti-rolling device are designed separately and installed independently, it often takes up more hull space, and is suitable for popularization and use on large and medium-sized ships.

[0003] For the current small ships and unmanned surface exploration ships, due to the relatively small space of the ship itself, if anti-rolling devices such as water tanks or fins are installed, a large amount of hull space will be occupied, resulting in the inability to arrange other equipment. Install

At the same time, in order to improve the comfort of the ship or meet the use conditions of the detection equipment, it is necessary to require the ship to have a certain stability, which causes the contradiction between the installation space and the use requirements
