Ship stabilization auxiliary icebreaking device based on Magnus principle

Abstract

The invention provides a ship stabilization auxiliary icebreaking device based on the Magnus principle, which comprises a cylindrical stabilization auxiliary icebreaking device which is arranged in a mounting notch at the side part of a ship body, a rotatable rotating body is arranged at one end of the mounting notch, and the cylindrical stabilization auxiliary icebreaking device is connected with the rotating body; the cylindrical anti-rolling auxiliary icebreaking device comprises a motor, a rotating shaft, a universal joint, a linear bearing, a cylindrical shell and a cylinder, and further comprises a built-in cylindrical surface which is arranged in the cylindrical shell, can stretch out and draw back in the axial direction of the cylindrical shell and can rotate along with the cylindrical shell, and a plurality of icebreaking cones are installed on the surface of the built-in cylindrical surface. The anti-rolling device has the anti-rolling effect when a ship is static or at a low navigational speed and also has the anti-rolling effect when the ship is at a medium-high navigational speed, meanwhile, when the ship works in an ice area, the built-in cylindrical surface with the icebreaking cone stored in the cylindrical shell is released to rotate along with the cylinder, and a certain auxiliary icebreaking effect is achieved, so that the ship works in a small-range ice area.

Description

technical field [0001] The invention relates to a ship anti-rolling auxiliary ice-breaking device based on the Magnus principle, and belongs to the technical field of ship equipment. Background technique [0002] When a ship sails at sea, it will encounter wind and waves, and it will sway. This phenomenon will seriously affect the normal navigation performance of the ship, and the structure of the hull and the objects in the ship will also be affected. The lateral sway of the ship will reduce the seaworthiness of the ship. damage to the hull structure, affect the normal operation of equipment and instruments, and cause cargo displacement or impact damage, and may also cause adverse effects such as comatose passengers. The Magnus effect refers to a phenomenon that in a viscous incompressible fluid, a moving rotating object is subjected to a lift force, which affects the path of the object in air or water. The principle of the Magnus effect force is as follows: the cylinder r...

Problems solved by technology

But it is anti-rolling and ice-breaking at the same time. When there is no need for ice-breaking, the cone will affect the steering efficiency of the rudder to the ship.
