Polar scientific investigation ship capable of breaking ice bidirectionally

Abstract

The invention relates to a polar scientific investigation ship capable of breaking ice bidirectionally, and belongs to the technical field of ship design and manufacturing. The ship comprises a bow line with an inclination angle, an icebreaking bow, an ice stopping front toe, a stern line, a full-revolving propeller, an inclined broadside and a tail sealing plate. An ice stopping front toe is arranged at the bottom of the prow, and an ice breaking bow is arranged above the ice stopping front toe; the stern part is provided with a full-revolving propeller; the stern shell comprises an outer convex plate, an inner concave plate, a horizontal outer plate, an inclined bottom plate and a tail sealing plate; and an ice breaking knife is arranged at the intersection of the outer convex plate and the inner concave plate. The bidirectional icebreaker is combined with the full-revolving propellers, so that the polar scientific investigation ship can conduct heading continuous icebreaking and collision icebreaking by means of the gravity of the ship and the icebreaking bow; and the stern is subjected to stern-direction icebreaking through suction of the icebreaking knife and the propeller. The ice-stopping front toe prevents the ship from rushing to the ice surface and losing the mechanical power. The ice breaking capacity of the polar region scientific investigation ship facing various ice conditions and the maneuverability of the polar region scientific investigation ship in an ice region are improved, and the practicability and safety of the ship are greatly improved.

Description

technical field [0001] The invention relates to a polar scientific research ship capable of bidirectional icebreaking, and belongs to the technical field of ship design and manufacture. Background technique [0002] The polar scientific research ship is a marine scientific research platform for polar marine resources, environmental investigation and scientific exploration in polar seas. There are first-year ice, multi-year ice and ice ridges in the polar sea ice area, and the ice conditions are very complex, which puts high demands on the ice-breaking capabilities of polar scientific research ships. For layer ice whose thickness is below the design ice thickness, heading continuous icebreaking can be used; in areas where multi-year ice or multi-year ice is mixed with first-year ice or when the local ice thickness is greater than the design ice thickness, heading collision icebreaking is required. When encountering thick ice ridge ice, the heading ice breaking function is us...

Problems solved by technology

Therefore, ice breaking in the stern direction is only an extremely important supplement for polar scientific research ships, but it cannot replace the ice breaking in the head direction.
