Description

За влено 14 но бр  1947 года в Комитет по изобретени м и открыти м при Совете Министров СССР за № 37029014 November 1947 were filed with the Committee on Inventions and Discoveries of the USSR Council of Ministers under No. 370290

Одним из распространенных приемов форсировани  ледоколами сплошного лед ного пол   вл етс  использование их живой силы и давлени , создаваемого винтами дл  вползани  на лед.One of the common methods used by icebreakers to force a continuous ice field is to use their manpower and pressure created by screws to crawl onto the ice.

Если несколько видоизменить устройство форштевн  ледокола и использовать живую силу ледокола и давление его винтов не только на вползание ледокола на лед, но и на надрез кромки лед ного пол , то можно значительно улучшить разрушение лед ного пол , что имеет целью предлагаема  конструкци  режущего устройства.If the icebreaker stem unit is somewhat modified and the icebreaker manpower is used and the pressure of its screws is not only on the icebreaker crawling onto the ice, but also on cutting the edge of the ice field, then the destruction of the ice floor can be significantly improved, which is the purpose of the proposed cutter design.

Отличительной особенностью насто щего изобретени   вл етс  выполнение режущего устройства в виде зубчатого ножа 2, жестко укрепленного непосредственно на форштевне.A distinctive feature of the present invention is the implementation of a cutting device in the form of a serrated knife 2 rigidly fixed directly on the stem.

Зубь  3 ножа расположены на всех его гран х, и толщина ножа увеличиваетс  по мере приближени  к килю.The tooth 3 of the knife is positioned on all its edges, and the thickness of the knife increases as you approach the keel.

На фиг. I схематически изображенFIG. I schematically depicted

вид сбоку носовой части ледокола, снабженной режущим устройством, на фиг. 2 - разрез по А-В фиг. 1.side view of the nose of the icebreaker, equipped with a cutting device; FIG. 2 is a section along the ab line of FIG. one.

На наклонной части форштевн  7 жестко укреплено режущее устройство.On the sloping part of the stem 7, the cutting device is rigidly fixed.

Толщина ножа может увеличиватьс  по мере приближени  к килю.The thickness of the knife may increase as you approach the keel.

Одновременно с вползанием ледокола на лед происходит прорезание льда ножом.Simultaneously with the icebreaker crawling onto the ice, ice is being cut through with a knife.
