Description

Technical Field

[0001] This utility model relates to the field of icebreaker technology, specifically to polar cryogenic icebreakers. Background Technology

[0002] Polar cryogenic icebreakers are vessels specifically designed for operation in polar regions (such as the Arctic and Antarctic) or extremely cold environments. These vessels are designed with sufficient strength and adaptability to meet the challenges of extreme temperatures and frozen waters. They are typically used for scientific research, logistics transportation, resource exploration, and other missions.

[0003] The shortcomings of existing technology: Most polar cryogenic icebreakers currently use a propeller to propel themselves forward. After breaking ice at the bow, the ice blocks move towards the propeller. Conventional polar cryogenic icebreakers only protect the outer surface of the propeller with a protective cover. However, during long-term icebreaking operations, ice blocks, floating ice, and ice fragments constantly impact the protective cover, which may cause wear or breakage of the cover, affecting the performance of the propeller. Utility Model Content

[0004] The purpose of this invention is to provide a polar cryogenic icebreaker hull to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polar cryogenic icebreaker hull, comprising a plurality of propeller bodies and an icebreaker body on which the propeller bodies are mounted, wherein both ends of the icebreaker body are provided with a flow-guiding mechanism for reducing ice blocks from approaching the propeller bodies, both ends of the icebreaker body are provided with a buffer mechanism for cushioning impact forces, and the outer surface of the propeller bodies is provided with a protective mechanism to prevent ice block impacts, wherein the flow-guiding mechanism includes: Several rotating rods are fixedly connected to both ends of the icebreaker body; Several arc-shaped plates are provided, and one end of the rotating rod is rotatably connected to an arc-shaped plate for diverting ice blocks to prevent them from impacting the propeller body.

[0006] Preferably, the buffer mechanism includes: Several telescopic rods are fixedly connected to both ends of the icebreaker body. One end of each telescopic rod is connected to both sides of the icebreaker body, and the other end of each telescopic rod is connected to the inner surface of the arc plate to facilitate limiting the position of the arc plate. Several springs are fixedly connected to the outer surface of the telescopic rod to buffer the impact force of ice blocks hitting the surface of the arc-shaped plate.

[0007] Preferably, the protective mechanism includes: Several protective covers are provided on the outer surface of the propeller body, and the surface of the protective covers is provided with circular grooves that are adapted to the propeller body to protect the outer surface of the propeller body; Several support frames are provided, with one end of the protective cover welded to it, and one end of the support frame is fixedly connected to the bottom of the icebreaker body to increase the stability of the protective cover.

[0008] Preferably, an arc-shaped cover is welded to one side of the propeller body, and a support column is fixedly connected inside the arc-shaped cover.

[0009] Preferably, one end of the support column is fixedly connected with barbs to increase the cutting capability of the propeller body.

[0010] Preferably, the arc-shaped plate is made of high manganese steel, which utilizes its work hardening properties to resist ice wear and impact.

[0011] Preferably, both the drainage mechanism and the buffer mechanism are provided with ultra-high molecular weight polyethylene to prevent ice from scratching them.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The polar cryogenic icebreaker hull has a flow diversion mechanism including a rotating rod and an arc-shaped plate. When the icebreaker breaks through the ice layer at the bow, the ice blocks are pushed to the rear by the hull. These ice blocks will move towards the propeller body area under the influence of water flow and hull design. When the ice blocks pass through the arc-shaped plate, the corrugated mechanism of the arc-shaped plate will push the ice blocks outward and push them away along the arc-shaped plate, reducing the impact of ice blocks on the propeller body. This helps protect the propeller body and avoids the continuous impact of ice blocks, floating ice and ice fragments during long-term icebreaking operations, which would affect the performance of the propeller body. 2. The polar cryogenic icebreaker hull has a buffer mechanism including telescopic rods and springs. When ice blocks collide with the curved plate, the reverse squeezing force of the springs is used to absorb and disperse some of the impact energy, buffering the impact force on the curved plate. The telescopic rods are used to increase its stability, allowing the curved plate to reset after being hit. This helps protect the curved plate, reduces wear and damage caused by ice block impacts, and thus extends the service life of the propeller body. Attached Figure Description

[0019] Example 1 Please see Figure 1-4As shown, the polar cryogenic icebreaker hull technical solution provided by this utility model includes: several propeller bodies 1 and an icebreaker body 2 on which the propeller bodies 1 are installed. Both ends of the icebreaker body 2 are provided with a diversion mechanism 3 to reduce the proximity of ice blocks to the propeller bodies 1. Both sides of the end of the icebreaker body 2 are provided with a buffer mechanism 4 to cushion the impact force. The outer surface of the propeller bodies 1 is provided with a protective mechanism 5 to prevent ice block impact. The diversion mechanism 3 includes a rotating rod 301 and an arc-shaped plate 302. The rotating rod 301 is fixedly connected to both ends of the icebreaker body 2, and one end of the rotating rod 301 rotates. An arc-shaped plate 302 is connected to the icebreaker body 2 to divert ice blocks and prevent them from impacting the propeller body 1. When the icebreaker body 2 breaks the ice layer at the bow, the ice blocks are pushed to the rear by the hull. These ice blocks will move towards the propeller body 1 area under the influence of water flow and hull design. When the ice blocks pass through the arc-shaped plate 302, the corrugated mechanism of the arc-shaped plate 302 pushes the ice blocks outward and away along the arc-shaped plate 302, reducing the impact of ice blocks on the propeller body 1. This helps protect the propeller body 1 and avoids the continuous impact of ice blocks, floating ice and broken ice during long-term icebreaking operations, which would affect the performance of the propeller body 1.

[0020] The buffer mechanism 4 includes a telescopic rod 401 and a spring 402. The telescopic rod 401 is fixedly connected to both ends of the icebreaker body 2. One end of the telescopic rod 401 is connected to both sides of the icebreaker body 2, and the other end of the telescopic rod 401 is connected to the inner surface of the arc plate 302 to facilitate limiting the position of the arc plate 302. The outer surface of the telescopic rod 401 is fixedly connected to a spring 402 for buffering the impact force of ice blocks hitting the surface of the arc plate 302. When ice blocks hit the arc plate 302, the reverse squeezing force of the spring 402 is used to absorb and disperse part of the impact energy to buffer the impact force on the arc plate 302. The telescopic rod 401 is used to increase its stability so that the arc plate 302 can be reset after being hit, which helps to protect the arc plate 302, reduce the wear and damage caused by the impact of ice blocks, and thus extend the service life of the propeller body 1.

[0021] The protective mechanism 5 includes a protective cover 501 and a support frame 502. The protective cover 501 is installed on the outer surface of the propeller body 1. The surface of the protective cover 501 has a circular groove that is adapted to the propeller body 1 to protect the outer surface of the propeller body 1. The support frame 502 is welded to one end of the protective cover 501. One end of the support frame 502 is fixedly connected to the bottom of the icebreaker body 2 to increase the stability of the protective cover 501. When some ice blocks are located around the propeller body 1, the protective cover 501 protects the propeller body 1 to prevent the ice blocks from directly hitting the propeller body 1 and affecting its propulsion performance.

[0022] An arc-shaped cover 6 is welded to one side of the propeller body 1, and a support column 7 is fixedly connected inside the arc-shaped cover 6.

[0023] One end of the support column 7 is fixedly connected to a barb 8 for increasing the cutting ability of the propeller body 1. When the propeller body 1 rotates and drives the barb 8 to rotate together, the sharpness of the barb 8 can be used to cut the foreign objects in the outside, reduce the risk of damage to the propeller body 1, and improve the ice-breaking efficiency, so that the ice blocks will not significantly affect the operation of the propeller body 1 during the propulsion process.

[0024] The curved plate is made of high manganese steel, which utilizes its work hardening properties to resist ice wear and impact.

[0025] Both the drainage mechanism 3 and the buffer mechanism 4 are covered with ultra-high molecular weight polyethylene to prevent ice from scratching them.

[0026] In this device, after the icebreaker body 2 breaks the ice layer at its bow, the ice blocks are pushed backward by the hull. These ice blocks move towards the propeller body 1 area under the influence of water flow and hull design. When the ice blocks pass the curved plate 302, the corrugated mechanism of the curved plate 302 pushes the ice blocks outward and along the curved plate 302. The reverse compression force of the spring 402 absorbs and disperses some of the impact energy to buffer the impact force on the curved plate 302. The telescopic rod 401 increases its stability so that the curved plate 302 returns to its original position after being hit. Subsequently, when some ice blocks are located around the propeller body 1, the protective cover 501 protects the propeller body 1 to prevent the ice blocks from directly hitting the propeller body 1 and affecting its propulsion performance.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
