Description

one

The invention relates to shipbuilding, in particular, to river transport vessels for pl & an in bit and solid ice.

A river transport vessel for sailing in a bit and solid ice is known, containing a hull with ice rinks, as well as reinforcement of the side plating l.

The disadvantages of the well-known vessel are low reliability of operation and low ice potential.

The purpose of the invention is to increase the reliability of operation and the icebreaking capacity of a river transport vessel.

The goal is achieved by reinforcement of the side plating containing a group of V-shaped profile beams rigidly attached to both sides and located on the ice, symmetrically on both sides of the center plane on the outer surface of the side plating, with

This beam is installed parallel to one another at an acute angle of 1-3 to the plane of the waterline and is made with sharp ends, and the top of the mentioned sharp angle of inclination of the beams to the plane of the waterline faces the bow, and the beams are provided with diaphragms fixed in them in the plane of the frames. FIG. 1 shows the vessel, view

The river transport vessel for navigation in bit and solid ice contains the hull 1 with ice 2 and also the reinforcement of the side plating. 20 The reinforcement of the side plating contains a group of beams 3 of the V-shaped profile, rigidly attached to both sides and 5 and located on the ice on the cross 2 symmetrically on both sides of the diametrical plane on the outer surface cL of the side plating. Beams -3 are installed parallel to each other at an acute angle of SzS 1-3 to the plane of the waterline (OHL) and are made with sharp ends 6. The top of the acute angle with the beams tilted to the plane of the waterline is facing toward the bow 7 and the beams 3 are fitted with reinforcements inside them the plane of the frames by the diaphragms 8. The length of the beams 3 extends over the entire width of the ice plane ca 2. The spacing of the beams 3 are above and below the ice box sa sa unity. The height of the beams, measured from the: rim edge to the ice one at ca 2, is such that they do not overhang the vessel’s width in relation to the height of the free beam 9. The vessel works as follows. When the hull of vessel t moves in solid or broken ice, the pointed beams 3 cause local destruction of the ice. Upon further movement of the vessel of relative ice floor, the edges of the floes fall on the upper scoops of the inclined beams 3, are lifted and broken, and the broken ice floes turn, not to prevent the vessel from moving. With the passage of the stern of the ship past the plated Kkhtsikh. the latter are thrown outward and upward by the walls of the beams 3 from the hull 1 of the vessel, thereby preventing their contact with the propeller and the rudders. Using the present invention makes it possible to increase the reliability of the vessel. The sharp edges of the equestrian 6 sufficiently extended beams, rio-r gradually penetrating into the ice, increase the impact time, and the inclined walls of the beams 3 direct the force of ice pressure at an acute angle to the skin. As a result, the pressure force of the ice on the ice casing is reduced and the residual deformations of the skin do not occur. The bending and shear forces acting on the beams 3 from the ice of the i / th floor are transmitted directly to the strong and rigid onboard set, which ensures a more rational functioning of the hull structures and reinforcement. The V-shaped beams and their inclination to the waterline make it possible to actively act on solid and floating ice, as a result of which the ship’s icebreaking is increased and the propulsion and rudders are protected from striking floating objects. The proposed mine has an increased durability of onboard hull structures and / allows extending the navigation time. Claims of the invention A river transport vessel for navigation in a bit and solid ice, containing a hull with ice skins, as well as reinforcement of the side plating, characterized in that, in order to increase Reliability of operation and ice-breaking, the reinforcement of the shell covering contains a group of beams V shaped profile, rigidly attached to both sides and located on ice on a symmetrical basis. both sides are diametrically on the outer surface of the side plating, while the beams are installed parallel to each other. The other is at an acute angle of 1-3 to the plane of the waterlines and is pointed with sharp ends, and Vespiina on the aforementioned acute angle of inclination of the beams to the plane of the waterline faces the bow end, the beams are equipped with diaphragms fixed inside them in the plane of the frames.
