Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 An icebreaking device for marine vessels includes a connecting plate 1 mounted on the bow, a movable block 2 mounted on the connecting plate 1, a sleeve 3 mounted on the movable block 2, a breaking cone 4 connected to the end of the sleeve 3 away from the movable block 2, baffles 5 rotatably connected to both sides of the breaking cone 4, connecting rods 6 rotatably connected to the inner sides of the two baffles 5, a moving ring 7 rotatably connected to the end of the connecting rod 6 away from the baffles 5, the moving ring 7 slidably connected to the sleeve 3, a first cylinder 8 connected inside the sleeve 3, and the output shaft of the first cylinder 8 connected to the moving ring 7.

[0022] The device is mounted on the bow of a ship via a connecting plate 1. As the ship moves, the crushing cone 4 moves forward, breaking up ice on the water surface to facilitate movement. Simultaneously, the first cylinder 8 is activated, and its output shaft moves the moving ring 7 synchronously. The moving ring 7, connected to the connecting rod 6, drives two baffles 5 to rotate, pushing the ice fragments to the sides of the ship. When the ice layer is thick and resistance is high, the first cylinder 8 can be moved forward a smaller distance, bringing the baffles 5 closer to the sides of the ship, thus reducing resistance. When the ice fragments are thin and resistance is low, the first cylinder 8 can be moved forward a longer distance, moving the baffles 5 away from the sides of the ship, increasing the contact area between the baffles 5 and the water surface, thereby expanding the ice-breaking area. This device has a simple structure, maintains a stable connection with the ship while the baffles 5 move, and allows for flexible adjustment of the distance between the two baffles 5 according to actual conditions. This makes it suitable for crushing ice of varying thicknesses, effectively improving its practicality.

[0023] Specifically, in this embodiment, a movable groove 9 is provided on the sleeve 3, and a push plate 10 is installed on the movable ring 7. The push plate 10 is connected to the output shaft of the first cylinder 8, so that the first cylinder 8 can drive the movable ring 7 to move through the push plate 10. The movable groove 9 allows the push plate 10 to move on the sleeve 3, thereby meeting the requirement of the first cylinder 8 driving the movable ring 7 to move.

[0025] Specifically, in the embodiment, the two baffles 5 are provided with a flow distribution plate 13 at the end away from the crushing cone 4, the flow distribution plate 13 is in a circular arc shape, the broken ice at the bow of the ship is pushed to the two sides of the ship under the action of the flow distribution plate 13 during the driving of the ship, so that the broken ice is prevented from colliding with the ship, and the abrasion degree of the surface of the ship is further reduced.

[0026] Specifically, in the embodiment, the two baffles 5 are provided with a plurality of partitions 14, the partitions 14 on the two baffles 5 are oppositely inclined, the broken ice is first contacted with the plurality of partitions 14, and the broken ice is discharged to the outside of the baffle 5 by the inclined partitions 14, so that the baffle 5 is prevented from being directly contacted with the broken ice, and the impact force of the broken ice on the baffle 5 is reduced.

[0027] Specifically, in the embodiment, the two baffles 5 are provided with a plurality of drill bits 15 driven by motors, the drill bits 15 are provided with blades 16, the length of the blade 16 is less than that of the drill bit 15, when the ship encounters an ice layer that is too thick during driving, the drill bit 15 is driven to rotate by clicking, and the blade 16 is synchronously rotated, so that the ice layer is first drilled and then broken by the blade 16.

[0028] Specifically, in the embodiment, the connecting plate 1 is provided with a second air cylinder 17 and an extension plate 18, the output shaft of the second air cylinder 17 is connected to the moving block 2, the moving block 2 is slidably connected to the extension plate 18 in the vertical direction, and a locking mechanism is arranged between the extension plate 18 and the moving block 2, so that the moving block 2 can be driven to move up and down by the second air cylinder 17 according to the different draught of the ship during use, the height of the crushing cone 4 and the baffle 5 is adjusted, and the device can meet the ice breaking requirements of different heights.
