Description

Technical Field

[0001] This utility model relates to the technical field of ship equipment, specifically to a ship icebreaking structure. Background Technology

[0002] When navigating in cold waters such as polar regions and high latitudes, ships often encounter ice barriers. In such cases, icebreaking structures are needed to break through the ice and ensure the ship's normal navigation.

[0003] Existing icebreaking structures for ships often suffer from problems such as low icebreaking efficiency and weak impact resistance. In some icebreaking structures, ice blocks tend to accumulate inside the structure during the icebreaking process, causing blockages, increasing the ship's forward resistance, and affecting the overall icebreaking effect and sailing speed.

[0004] Therefore, those skilled in the art have provided a ship icebreaking structure to solve the problems mentioned. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a ship icebreaking structure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A ship icebreaking structure, comprising:

[0008] Mounting plates are installed on the bottom of the vessel on the side facing the ice.

[0009] Three cutting plates are provided, and the vertical spacing between adjacent cutting plates increases uniformly from the middle to both ends, for use in ship movement and icebreaking;

[0010] An arc-shaped plate is evenly fixed between adjacent cutting plates and is inclined towards the end of the cutting plate;

[0011] When the cutting plate cuts the ice block, a guide area for the ice block to move laterally is formed between the two cutting plates, and the side of the arc-shaped plate facing the ice block forms a continuous guide surface for the ice block.

[0012] Preferably, a vertical plate is fixedly installed on one side of the mounting plate, and the vertical plate is located in the middle of the three cutting plates.

[0013] Preferably, the cutting plate has multiple notches, and the notches are located on the concave side of the arc-shaped plate.

[0014] Preferably, the cutting plate located in the middle position is horizontally arranged, and the middle parts of the cutting plates located at the top and bottom are bent towards the middle position.

[0015] Preferably, the mounting plate has multiple mounting holes, and the multiple mounting holes are symmetrically arranged.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] As the ship moves forward, the central cutting plate first contacts the ice and applies impact force, initially breaking the ice. The broken ice then flows to both sides, with the distance between adjacent cutting plates gradually increasing from the middle to both ends. During the flow splitting process, the contact area between the ice and the cutting plates decreases accordingly, thus significantly reducing the frictional force between the cutting plates and the ice. This significantly reduces the resistance experienced by the ice during the splitting process, preventing ice from accumulating between the cutting plates and causing blockages, and reducing the additional resistance generated by icebreaking as the ship moves forward, making the ship move more smoothly. When encountering larger ice blocks, the curved surface of the curved plate does not directly and rigidly collide with the ice block. Instead, the curved surface guides the larger ice block to slide along the inclined direction, effectively improving the ship's icebreaking efficiency and sailing speed. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] A ship icebreaking structure, referring to Figure 1-3 ,include:

[0025] Mounting plate 1, installed on the side of the ship's hull facing the ice, is shaped like a "V" and has a vertical cutting effect. As the fundamental load-bearing component of the entire icebreaking structure, it is made of high-strength, wear-resistant steel. It can directly withstand the impact force generated by ice blocks and, through its rigidity, evenly transfer the force to the main structure of the ship's hull, preventing localized stress concentration that could damage the ship. Furthermore, the surface of mounting plate 1 undergoes a special anti-rust and wear-resistant treatment, effectively resisting seawater corrosion and wear caused by ice block friction, extending the service life of the entire icebreaking structure.

[0026] Three cutting plates 2 are provided, with the vertical spacing between adjacent cutting plates 2 increasing uniformly from the middle to both ends. These are used for icebreaking by impact as the ship moves forward. When the ship moves forward, the middle cutting plate 2 first contacts the ice and applies impact force, initially breaking the ice. The broken ice then flows to both sides. Because the spacing between adjacent cutting plates 2 gradually increases from the middle to both ends, the contact area between the ice and the cutting plates 2 decreases during the flow-out process, thus significantly reducing the friction between the cutting plates 2 and the ice. The direct benefit of this design is that the resistance experienced by the ice during flow-out is significantly reduced. This avoids ice accumulation between the cutting plates 2, preventing blockages, and reduces the additional resistance generated by icebreaking during ship movement, making the ship move more smoothly. Especially when facing thicker ice layers, it effectively improves the ship's icebreaking efficiency and sailing speed.

[0027] Furthermore, the cutting plate 2 located in the middle is horizontally positioned. This horizontally positioned middle cutting plate 2 can serve as the "main force" for icebreaking. Its horizontal posture ensures that when impacting ice blocks, the direction of force is consistent with the direction of the ship's forward movement, maximizing the utilization efficiency of the impact force and avoiding force dispersion due to angular deviation. Meanwhile, the middle sections of the cutting plates 2 located at the top and bottom are bent towards the center. This bending design can form a wrap-around icebreaking area. When ice blocks flow towards the top or bottom, the bent cutting plates 2 can play an auxiliary guiding role for the ice blocks, further guiding them away from the sides of the ship. At the same time, it can also provide some protection for the middle cutting plate 2, preventing larger ice blocks from directly impacting the middle cutting plate 2 from the top or bottom, thereby improving the impact resistance of the entire cutting plate 2 assembly.

[0028] The curved plate 3 is uniformly fixed between adjacent cutting plates 2. Its curved structure, rather than a planar one, serves two purposes. First, when subjected to impact, the curved surface disperses the force along its arc, preventing excessive local stress that could lead to structural deformation. This significantly increases the connection stability between the cutting plates 2, effectively preventing bending damage due to uneven stress during ice breaking and further enhancing the overall structural strength of the cutting plates 2. Second, its inclined design towards the ends of the cutting plates 2 prevents direct rigid collisions with larger ice blocks. Instead, the curved surface guides the larger ice blocks to slide along the inclined direction. Simultaneously, the curved structure itself possesses a certain degree of elastic deformation, absorbing some impact energy through slight deformation, thus providing a buffer and reducing the direct impact of larger ice blocks on the cutting plates 2 and mounting plate 1, lowering the risk of damage to the entire ice breaking structure.

[0029] When the cutting plate 2 cuts the ice, a guide area for the lateral movement of the ice is formed between the two cutting plates 2. The arc plate 3 faces the side of the ice to form a continuous guide surface for the ice. This continuous guide surface can prevent the ice from getting stuck due to encountering protrusions or sharp edges during movement, ensuring that the ice always flows smoothly to both sides. Compared with a discontinuous guide structure, it can greatly reduce the resistance of the ship, while reducing the irregular wear of the ice-breaking structure by the ice and extending the service life of the components.

[0030] A vertical plate 4 is fixedly installed on one side of the mounting plate 1, and the vertical plate 4 is located in the middle of the three cutting plates 2. It is used for vertical cutting of incoming ice blocks, which can improve the cutting effect of the cutting plates 2 and the mounting plate 1 and increase the cutting efficiency.

[0031] Multiple notches 5 are provided on the cutting plate 2, and the notches 5 are located on the concave side of the curved plate 3. The design of the notches 5 is mainly based on the dual considerations of "lightweighting" and "aiding ice removal": on the one hand, the notches 5 on the cutting plate 2 can reduce the weight of the cutting plate 2 itself without affecting the overall structural strength, reduce the load on the bottom of the ship, and reduce the contact area between the ice and the cutting plate 2, further reducing frictional resistance; on the other hand, since the notches 5 are located on the concave side of the curved plate 3, when the ice flows along the concave surface of the curved plate 3, the notches 5 can form a "channel" to help small ice blocks be discharged from between the cutting plates 2 more quickly, avoid the accumulation of small ice blocks in the concave area of ​​the curved plate 3, ensure the smooth flow of ice blocks, and indirectly improve the navigation efficiency of the ship.

[0032] The mounting plate 1 has multiple mounting holes 6, which are symmetrically arranged. The symmetrical arrangement of the mounting holes 6 is to ensure that the force is evenly distributed when the icebreaking structure is installed to the bottom of the ship. When the mounting plate 1 is connected to the bottom of the ship by fasteners such as bolts passing through the mounting holes 6, the symmetrical hole positions allow the fastening force of the fasteners to be evenly applied to the mounting plate 1. This avoids deformation caused by excessive local stress on the mounting plate 1 due to asymmetrical mounting hole positions, and ensures the stability and firmness of the connection between the icebreaking structure and the bottom of the ship.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
