A ram-type ice-breaking auxiliary device installed on the bow

Abstract

The invention discloses a collision-type ice-breaking auxiliary device installed on the bow of a ship, which comprises a cavity. A sliding seat is fixedly connected to the upper side of the cavity and located on both side walls of the hull. The sliding seat is slidably connected to a sliding plate. A support plate is fixedly connected, and a plurality of saw blades are slidably connected under the support plate. The front ends of the plurality of saw blades are all rotatably connected with connecting rods, and the upper ends of the plurality of connecting rods are all rotatably socketed on the side wall of the crankshaft, and the crankshaft passes through the The driving mechanism drives the rotation. The invention starts the driving mechanism to make the crankshaft reciprocate up and down with a plurality of connecting rods. At this time, the connecting rods will reciprocate with the saw blades on the lower side of the support plate, so that the edge of the ice layer can be cut. Saw and cut the bow into a slope that is convenient for the bow to drive to the ice surface, and increase the forward horsepower of the hull, so that the bow can be easily climbed and ridden on the ice along the sawn slope, reducing the difficulty of climbing and riding the bow on the ice. The ice layer is crushed by the weight of the bow, and then the icebreaking operation is completed.

Description

technical field [0001] The invention relates to the technical field of ice-breaking ice-breaking of an icebreaker, in particular to an auxiliary ice-breaking device installed on the bow of a ship, which belongs to the field of ships and marine engineering. Background technique [0002] At present, some harbors or seas located in polar regions, cold regions or high latitude regions are often frozen, and the navigation channels are seriously blocked, and the ice layer will damage and affect the navigation of ships. Therefore, in order to ensure the smooth navigation of ships, icebreakers are It has become an existing indispensable tool. When the existing icebreaker is breaking ice, many icebreaking tasks do not rely on rushing into the ice layer, but climb the bow of the ship onto the ice surface, so that the ice layer under the bow receives the bow. The heavy pressure quickly ruptures to break the ice. This climbing and riding ice-breaking method needs to use the ballast wat...

AI Technical Summary

Problems solved by technology

When the ice layer is thicker (for example, more than 1.5 meters), and the edges of the ice layer are mostly vertical steep surfaces, and the ice layer is all above the water surface, if you want to climb the bow of the ship on the ice surface at this time It is more difficult, so that the icebreaker cannot complete the icebreaking operation and cannot move forward
