Description

Technical Field

[0001] The utility model relates to the technical field of ship icebreaking, in particular to a ship icebreaking structure. Background Art

[0002] A ship is a means of transportation that can sail or anchor in waters for transportation or operations. Ice will condense in the waters of extremely cold areas, and the ice will have a significant impact on the navigation of ships. In order for the ship to sail normally, an icebreaking structure is generally installed on the hull.

[0003] After searching, in the prior art, a utility model with a publication number of CN219361279U discloses a new ice-breaking structure that is convenient for ship installation, and relates to the field of ship ice-breaking technology. The new ice-breaking structure that is convenient for ship installation comprises a front guard plate, and the front guard plate is in a “>” shape. A support plate is fixed to both sides of the front guard plate by bolts, and a rotating shaft is connected to the two support plates by bearings, and the other ends of the two rotating shafts are fixed to the ice-breaking plate by bearing seats, and the ice-breaking plate is fixed to the upper guard plate by bolts. In the utility model, the staff overlaps the connecting frame on the front side of the hull, and the locking plate is clamped on the inner side of the hull. By twisting the threaded connecting rod, the clamping plate is clamped on the hull. When the ship moves forward, the ice-breaking plate will separate the ice surface, start the motors on both sides, and the motors drive the rotating shafts to rotate, thereby driving the ice-breaking blades to rotate, and the ice separated to the two sides is broken, so as to prevent the safety hazard of large ice blocks scratching the hull when the hull passes.

[0004] And the prior art, a ship icebreaking device with announcement number CN220948440U.

[0005] The above methods still have the disadvantages of complex structure, inconvenient installation and high cost. At the same time, the above methods ignore the fact that the ship is affected by factors such as waves or wind in the water, and sometimes it will travel in a swinging state. When the bow swings, it is not convenient to break ice and the practicality is poor. Therefore, we propose a ship icebreaking structure to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a ship icebreaking structure to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a mounting frame, the outer wall of which is connected to a plurality of first ice-breaking teeth, second ice-breaking teeth are arranged above the first ice-breaking teeth, and the inner cavity of the mounting frame is penetrated by a plurality of mounting holes.

[0008] Preferably, there are three groups of the first ice-breaking teeth, and the three groups of first ice-breaking teeth are arranged in a stepped manner.

[0009] Preferably, the cross-sections of the first ice-breaking teeth and the second ice-breaking teeth are both triangular.

[0010] Preferably, the first ice-breaking teeth and the second ice-breaking teeth are arranged in a diamond shape.

[0011] Preferably, a plurality of reinforcing ribs are distributed on the outer ring of the second ice-breaking teeth, and the reinforcing ribs are triangular in shape.

[0012] Preferably, the mounting frame is made of steel material, and the first ice-breaking teeth and the second ice-breaking teeth are made of stainless steel material.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The ship's icebreaking structure uses the first icebreaking teeth. When the ship is sailing normally on the water, after the first icebreaking teeth come into contact with the ice, the impact force of the ship is concentrated on the edge of the first icebreaking teeth, and then the ice is rammed and destroyed by the first icebreaking teeth to achieve the purpose of breaking the ice. Since there is a certain distance between the three groups of first icebreaking teeth, when the ship swings in the water, the first icebreaking teeth can achieve a cutting effect on the ice, thereby achieving the purpose of breaking the ice. The overall structure is relatively simple, the ship has a light load, the balance of both ends of the hull is easy to control, and no additional energy is required to drive it, the use cost is low, and the practicality is high.

[0015] 2. The ship's icebreaking structure uses the first icebreaking tooth and the second icebreaking tooth in coordination. When the bow is lifted up and falls, the edge of the bottom of the first icebreaking tooth can concentrate the gravity of the ship, and then when the first icebreaking tooth contacts the ice layer, the ice layer is squeezed and destroyed. When the bow sinks and rises, the lifting force of the ship is concentrated on the edge of the second icebreaking tooth, and the ice layer is lifted and destroyed from the bottom. The provision of the second icebreaking tooth can avoid the first icebreaking tooth from being stuck under the ice layer, thereby preventing the first icebreaking tooth from being damaged, thereby improving the practicality of the structure.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a technical solution for a ship icebreaking structure:

[0023] Example:

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a mounting frame 1, the outer wall of the mounting frame 1 is connected to a plurality of first ice-breaking teeth 2, second ice-breaking teeth 3 are arranged above the first ice-breaking teeth 2, and a plurality of mounting holes 5 are opened through the inner cavity of the mounting frame 1.

[0025] There are three groups of first ice-breaking teeth 2, and the three groups of first ice-breaking teeth 2 are arranged in a stepped manner.

[0026] In this embodiment, when in use, the mounting frame 1 is connected to the end of the ship through the mounting hole 5. Then, when the ship is sailing normally on the water surface, after the first ice-breaking tooth 2 comes into contact with the ice, the impact force of the ship is concentrated on the edge of the first ice-breaking tooth 2, and then the first ice-breaking tooth 2 collides and destroys the ice to achieve the purpose of breaking ice. Figure 1 As shown, the three groups of first ice-breaking teeth 2 are spaced a certain distance apart. When the ship swings in the water, the first ice-breaking teeth 2 can cut the ice, thereby achieving the purpose of icebreaking. The overall structure is relatively simple, the ship has a light load, the balance of both ends of the hull is easy to control, and no additional energy is required to drive it. The use cost is low and the practicality is high.

[0027] Among them, Figure 2 As shown, the cross sections of the first ice-breaking teeth 2 and the second ice-breaking teeth 3 are both triangular.

[0028] The first ice-breaking teeth 2 and the second ice-breaking teeth 3 are arranged in a rhombus shape.

[0029] In this embodiment, the ship may rise and fall during sailing due to factors such as waves or wind. When the bow is lifted up and falls down, the edge at the bottom of the first ice-breaking tooth 2 can concentrate the gravity of the ship, and then when the first ice-breaking tooth 2 contacts the ice layer, the ice layer is squeezed and destroyed. When the bow sinks and rises, the lifting force of the ship is concentrated on the edge of the second ice-breaking tooth 3, and the ice layer is lifted and destroyed from the bottom. The provision of the second ice-breaking tooth 3 can avoid the first ice-breaking tooth 2 from being stuck under the ice layer, thereby preventing the first ice-breaking tooth 2 from being damaged, thereby improving the practicality of the structure.

[0030] Among them, Figure 1 and Figure 4 As shown, a plurality of reinforcing ribs 4 are distributed on the outer circle of the second ice-breaking teeth 3, and the reinforcing ribs 4 are triangular in shape.

[0031] In this embodiment, the provision of the reinforcing rib 4 improves the connection strength between the mounting frame 1, the first ice-breaking tooth 2 and the second ice-breaking tooth 3, and improves the overall firmness of the structure, making the structure less prone to deformation, thereby increasing the service life of the structure.

[0032] The mounting frame 1 is made of steel material, and the first ice-breaking teeth 2 and the second ice-breaking teeth 3 are made of stainless steel material.

[0033] In this embodiment, steel has high strength and is not easy to corrode. The ice-breaking structure made of steel can improve the durability of the product. Stainless steel has improved strength and corrosion resistance due to the addition of chromium on the basis of steel, but its cost is also higher than steel. Therefore, the mounting frame 1 that is not often in direct contact with ice cubes is made of steel, and the first ice-breaking teeth 2 and the second ice-breaking teeth 3 that need to be in direct contact with ice cubes are made of stainless steel. This can save overall costs while ensuring a good ice-breaking ability of the structure, thereby further improving the overall practicality.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
