(54) ЛЕДООЧИСТИТЕЛЬНАЯ ПРИСТАВКА(54) ICE CLEANER

II

Изобретение относитс к судостроению, в частности к ледоочистительным приставкам .This invention relates to shipbuilding, in particular to ice-cleaning attachments.

Известна ледоочистительна приставка, содержаща корпус с ледоразвод щим клином , располо 1 енным в носовой части ее днища и боковыми ледорезными ножами и сцепное устройство, посредством которого приставка св зана с самоходным судном 1.The ice-cleaning attachment is known, comprising a hull with an ice-spreading wedge located 1 in the nose part of its bottom and side ice-cutting knives and a coupling device by means of which the attachment is connected to a self-propelled vessel 1.

Однако известна приставка обладает малой эффективностью эксплуатации и -ограниченным диапазоном эксплуатационных режимов.However, the known prefix has a low operating efficiency and a limited range of operating modes.

Цель изобретени - повыщение эффективности эксплуатации и расщирение диапазона эксплуатационных режимов ледоочистительной приставки.The purpose of the invention is to increase the operating efficiency and expand the range of operating modes of the ice-clearing attachment.

Цель достигаетс тем, что в кормовой части днища приставки выполнен дополнительный ледоразвод щий клин, обращенный острием в сторону кормы, сцепное устройство сбдержит две жесткие буксирные т ги с механизмом изменени их длины, щарнирно закрепленные одним концом по бортам, в .носовой оконечности приставки и щарнирно св занные другим концом с кормовой оконечностью судна, при этом щарниры буксирных т г выполнены с возможностью поворота в горизонтальной и вертикальнойThe goal is achieved by the fact that in the aft part of the bottom of the attachment an additional ice-spreading wedge is turned, pointing at the stern with the tip, the coupling device will hold two rigid towing rods with a mechanism for changing their length, hinged at one end on the sides, at the extension end of the attachment and sliding connected to the aft end of the vessel at the other end, while the towing hinges are rotatable in the horizontal and vertical direction.

На фиг; 1 изображена ледоочистительна приставка с ледоколом, вид сбоку; на фиг. 2-то же, в плане .Fig; 1 shows an ice-cleaning attachment with an icebreaker, side view; in fig. 2 is the same in terms of.

Ледоочистительна приставка содержит корпус 1, в днищевой части которого расположены носовой 2 и кормовой 3 ледоразвод щие клинь . В плоскости бортов носовой оконечности установлены ледорезные fO ножи 4.,-Приставка соедин етс с ледоколом 5 при помощи сцепного устройства, выполненного в виде жестких буксирных т г 6, концы которых установлены в щарнирах 7 и 8. Т ги снабжены механизмом 9 изменени длины.The ice-cleaning attachment comprises a housing 1, in the bottom of which the bow 2 and the stern 3 ice-spreading wedges are located. Ice-cutting fO knives 4 are installed in the plane of the bows of the bow tip. The prefix is connected to the icebreaker 5 by means of a coupling device made in the form of rigid towing bars 6, the ends of which are installed in bows 7 and 8. Tee are equipped with a mechanism 9 for changing length.

Ледоочистительна приставка работает следующим образом.Ice cleaning console works as follows.

Claims

When an icebreaker is operating, a jet of water from its screws moves the broken ice to the ice-cleaning attachment to the forward stroke. When the broken ice hits the surface of the ice-spreading wedge 2, a transverse component of the force is formed, which contributes to the intensive evacuation of the broken ice outside the channel. The inclined part of the ice-breaking wedge is used to submerge the broken ice that flows under the hull, which means that it will be removed under the edge of the channel. When moving an icebreaker with an ice-cleaner with a prefix on variable courses, a mechanism 9 for changing the length of rigid tg is activated, which shortens one of them and the other lengthens by an amount corresponding to the course of the vessel. Thus, it is possible to move the attachment behind the icebreaker on a curved motion path without jamming. In the event that the icebreaker or an attachment receive trim on the stern or bow during operation, the rods 6 are free to rotate around the axes of the hinges 7 and 8. The icebreaker’s reversal (r; i) fi operation by forays) the connection between the batten icebreaker II is unchanged. Stern CLI1 3 () gfy this channel from broken ice, OST: .11..god in the channel. Mpi; .1 below and the composition of the front, the edges of the ice channel are leveled with ice-cutting knives 4., which protects the conducted vessels from being damaged when they are on the edge of the channel. If necessary, the console can be used to work in the mode of talking. The invention makes it possible to use a jet stream of water from the working icebreaker ridge screws to efficiently clean the ice channel laid by the icebreaker, to arrange the ice channel cleaning composition in which the console works in towed mode, and also to clean the ice channel in the reverse direction of the composition. The invention is an ice-cleaning attachment comprising a hull with an ice-spreading wedge located in the fore part of its bottom and side ice-cutting knives and a hitch, by means of which the attachment is connected to a self-propelled vessel, which in order to increase operating efficiency and sweep the range operating modes, in the aft part of the bottom of the attachment there is an additional ice-breaker and a wedge, which points with the tip towards the stern, the coupling device contains two towbars with a mechanism The changes in their length, which are hinged at one end along the sides of the top end of the attachment and hinged at the other end to the stern end of the vessel, while the towing hinge hinges are rotatable in horizontal and vertical planes.
