Description

Technical Field

[0001] The invention relates to the technical field of icebreaker devices, in particular to an icebreaker device for polar icebreaker ships. Background Art

[0002] The polar regions refer to the north and south poles of the earth. The temperature in most areas of the Antarctic and the Arctic rarely rises above 0°C. In the extremely cold areas of the polar regions, the surface of the ocean will freeze, which is called sea ice. Icebreakers are service ships used to break up ice on the water surface, open up waterways, and ensure that ships enter and exit frozen ports and anchorages, or guide ships to sail in ice areas. Icebreakers are divided into river, lake, harbor or ocean icebreakers. Their hulls are short and wide, with a small length-to-width ratio, the bottom is upturned at the bow and stern, the bow column is pointed and tilted forward, the overall strength is high, the bow and stern and the waterline area are reinforced with thick steel plates and dense frames, and the propulsion system mostly uses dual-axis and multi-propeller devices with more than dual-axis, and is powered by diesel engines. When breaking ice, the bow squeezes the ice layer to break ice continuously or repeatedly break ice while moving; After searching, the Chinese utility model patent with announcement number CN205273806U discloses a rapid icebreaking device for icebreakers. When the power is turned on, the electric saw cutting principle is used to increase the icebreaking ability of the icebreaker. The spiral saw rotates continuously to break ice over a large area and break thick ice and even icebergs. At the same time, the spiral saws on both sides rotate clockwise to push the broken ice backwards. When the spiral saws rotate continuously, they will generate a force to pull the icebreaker forward, reduce the forward resistance of the hull, and accelerate the rapid icebreaking of the icebreaker. However, the utility model still has the following problems: 1. When breaking ice in polar regions, the icebreaker breaks the ice surface by continuously rotating the spiral saw and contacting the ice surface. However, when breaking ice, the spiral saw will be between the moving icebreaker and the stationary ice, which makes it easy for the spiral saw to be squeezed by the icebreaker and damaged; 2. Using only one spiral saw to break the ice surface will result in insufficient ice breaking effect, making it difficult to assist in ice breaking.

[0003] In view of this, we propose an icebreaking device for polar icebreakers. Summary of the invention

[0004] The object of the present invention is to provide an icebreaking device for a polar icebreaker to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An icebreaking device for a polar icebreaker comprises a V-shaped block, an icebreaking mechanism is arranged on one side of the V-shaped block, and a cutting mechanism is arranged on one side of the icebreaking mechanism; The ice-breaking mechanism includes first connecting bars symmetrically arranged. One end of each first connecting bar is fixedly connected to one side of a V-shaped block. A rotating rod is rotatably connected to the opposite side of each first connecting bar. An eccentric wheel is fixedly sleeved on the rotating rod. A connecting frame is arranged on the surface of the eccentric wheel. A first fixing rod is fixedly connected to the bottom of the connecting frame. A first ice-breaking hammer is fixedly connected to the bottom of the first fixing rod. A hollow block is slidably arranged on the surface of the connecting frame. A second fixing rod is fixedly connected to one side of the hollow block. The two ends of the second fixing rod are respectively fixedly connected to one side of the first connecting bar. A second connecting bar is fixedly connected to the bottom of one of the first connecting bars. A support plate is fixedly connected to the top of the second connecting bar. A motor is fixedly connected to the top of the support plate. The output shaft of the motor is fixedly connected to one end of the rotating rod.

[0006] Preferably, the cutting mechanism includes L-shaped fixing plates symmetrically arranged. One end of each L-shaped fixing plate is fixedly connected to the first connecting bar. A rotating block is rotatably connected to the free end of each L-shaped fixing plate. A cutting disc is fixedly connected to one side of the rotating block. A first synchronous pulley is fixedly connected to the surface of the rotating block. A second synchronous pulley is fixedly connected to the surface of the rotating rod. A synchronous belt is jointly sleeved on the surfaces of the first synchronous pulley and the second synchronous pulley. The teeth of the synchronous belt are meshed with the teeth of the first synchronous pulley and the second synchronous pulley respectively.

[0007] Preferably, a hollow shell is fixedly connected to one side of the cutting disc. A resistance wire is arranged in the inner cavity of the hollow shell. The surface of the resistance wire is fixedly connected to one side of the cutting disc.

[0008] Preferably, connecting rods are fixedly connected to both sides of the first ice-breaking hammer. The other ends of the connecting rods are fixedly connected to second ice-breaking hammers.

[0009] Preferably, a stop block is arranged on one side of the first synchronous pulley. The top of the stop block is fixedly connected to the surface of the rotating block.

[0010] Preferably, a limiting plate is arranged on one side of the hollow shell. The one side of the limiting plate is fixedly connected to one side of the L-shaped fixing plate.

[0011] Preferably, reinforcing rods are fixedly connected to both sides of the first fixing rod. The bottoms of the reinforcing rods are fixedly connected to the tops of the second ice-breaking hammers.

[0012] Preferably, a protective shell is arranged on the surface of the motor. The bottom of the protective shell is fixedly connected to the top of the support plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The ice-breaking device for the polar icebreaker drives the eccentric wheel to move eccentrically through a rotating rod. The eccentric wheel drives the connecting frame and the first ice-breaking hammer to move up and down reciprocally to pre-strike the ice surface, which can cause cracks on the ice surface. Moreover, the first ice-breaking hammer is located above the ice surface and strikes downward, so that the ice-breaking mechanism is not easily damaged by the extrusion of the icebreaker, solving the problem that the spiral saw is easily damaged by the extrusion of the icebreaker.

[0014] 2. The ice-breaking device for the polar icebreaker drives the second synchronous wheel to rotate through a rotating rod. The second synchronous wheel drives the first synchronous wheel and the cutting disc to rotate through a synchronous belt. At this time, the rotating cutting disc can pre-cut the ice surface, realizing the appearance of cracks on the ice surface, making the ice layer easier to be broken by the impact force of the icebreaker. Then, combined with the strike of the first ice-breaking hammer on the ice surface, the pre-treatment ice-breaking effect on the ice surface can be better, solving the problem that only using one spiral saw to break the ice surface results in a poor ice-breaking effect.

[0015] 3. The ice-breaking device for the polar icebreaker uses a resistance wire to heat the cutting disc, realizing that when the cutting disc cuts the ice surface, it can make the cutting effect better through heating, solving the problem that the cutting effect of the cutting disc is not good enough.

[0016] 4. The first ice-breaking hammer of the ice-breaking device for the polar icebreaker drives the second ice-breaking hammer to move up and down together through a connecting rod. The second ice-breaking hammer cooperates with the first ice-breaking hammer to strike the ice block together, making the striking range wider and the effect better, solving the problem that the striking effect of a single first ice-breaking hammer is poor.

[0017] 5. The ice-breaking device for the polar icebreaker uses a limiting plate to limit the cutting disc, so that the cutting disc is not easily inclined on one side of the L-shaped fixing plate, and thus can cut stably, solving the problem that the limiting plate is easily inclined.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "several" means two or more unless otherwise specifically defined.

[0024] Please refer to Figures 1-7 as shown below. The present invention provides a technical solution: An ice-breaking device for a polar icebreaker, comprising a V-shaped block 1. One side of the V-shaped block 1 is provided with an ice-breaking mechanism 2, and one side of the ice-breaking mechanism 2 is provided with a cutting mechanism 3; The ice-breaking mechanism 2 includes symmetrically arranged first connecting bars 201. One end of the first connecting bar 201 is fixedly connected to one side of the V-shaped block 1. A rotating rod 202 is rotatably connected to the opposite side of the first connecting bar 201. An eccentric wheel 203 is fixedly sleeved on the rotating rod 202. A connecting frame 204 is arranged on the surface of the eccentric wheel 203. A first fixing rod 205 is fixedly connected to the bottom of the connecting frame 204. A first ice-breaking hammer 206 is fixedly connected to the bottom of the first fixing rod 205. A hollow block 207 is slidably arranged on the surface of the connecting frame 204. A second fixing rod 208 is fixedly connected to one side of the hollow block 207. Both ends of the second fixing rod 208 are respectively fixedly connected to one side of the first connecting bar 201. A second connecting bar 210 is fixedly connected to the bottom of one side of the first connecting bar 201. A support plate 211 is fixedly connected to the top of the second connecting bar 210. A motor 209 is fixedly connected to the top of the support plate 211. The output shaft of the motor 209 is fixedly connected to one end of the rotating rod 202.

[0025] It should be noted that the V-shaped block 1 is mainly connected to the bow of the icebreaker by welding. The first connecting bar 201 can be connected to the V-shaped block 1, and the inside can be used to place the rotating rod 202, so that the rotating rod 202 can drive the eccentric wheel 203 to rotate together by rotation. The rotating rod 202 is connected to the eccentric position of the eccentric wheel 203, so that the rotating rod 202 can drive the eccentric wheel 203 to perform eccentric motion when rotating. When the eccentric wheel 203 rotates eccentrically, it can squeeze and drive the connecting frame 204 to move up and down reciprocally. The first fixing rod 205 can connect the connecting frame 204 and the first ice-breaking hammer 206, and the first ice-breaking hammer 206 can contact the ice surface, so that when the connecting frame 204 moves up and down reciprocally, it can drive the first ice-breaking hammer 206 to move up and down together through the first fixing rod 205. The first ice-breaking hammer 206 can pre-hammer the ice surface by hammering up and down, so that cracks are generated on the surface of the ice block, and the impact force of the hammering will generate stress inside the ice block, resulting in the destruction of the internal structure of the ice block, making the ice block easier to be broken by the subsequent icebreaker. At the same time, the ice-breaking mechanism 2 is located on the upper side of the ice surface and hammers downward, so that the ice-breaking mechanism 2 is not easily damaged by being squeezed by the icebreaker. Among them, the second fixing rod 208 can connect the hollow block 207, and the hollow block 207 can limit the connecting frame 204, so that the connecting frame 204 can be stable on the surface of the eccentric wheel 203. The second connecting bar 210 can support the motor 209 through the support plate 211, so that the motor 209 can drive the rotating rod 202 to rotate, making the rotation of the rotating rod 202 more convenient.

[0026] In this embodiment, the cutting mechanism 3 includes symmetrically arranged L-shaped fixing plates 301. One end of the L-shaped fixing plate 301 is fixedly connected to the first connecting bar 201. A rotating block 302 is rotatably connected to the free end of the L-shaped fixing plate 301. A cutting disc 303 is fixedly connected to one side of the rotating block 302. A first synchronous pulley 304 is fixedly connected to the surface of the rotating block 302. A second synchronous pulley 306 is fixedly connected to the surface of the rotating rod 202. A synchronous belt 305 is sleeved on the surfaces of the first synchronous pulley 304 and the second synchronous pulley 306. The teeth of the synchronous belt 305 are meshed with the teeth of the first synchronous pulley 304 and the second synchronous pulley 306 respectively.

[0027] One end of the L-shaped fixing plate 301 is fixedly connected to the first connecting bar 201. A rotating block 302 is rotatably connected to the free end of the L-shaped fixing plate 301, enabling the rotating block 302 to rotate. The first synchronous pulley 304 can be connected to the surface of the rotating block 302, while the second synchronous pulley 306 can be connected to the surface of the rotating rod 202, enabling the rotating rod 202 to drive the second synchronous pulley 306 to rotate. Moreover, the synchronous belt 305 is connected to both the first synchronous pulley 304 and the second synchronous pulley 306, enabling the second synchronous pulley 306 to drive the first synchronous pulley 304 and the rotating block 302 to rotate together through the synchronous belt 305 when the second synchronous pulley 306 rotates. The cutting disc 303 is located on one side of the rotating block 302, enabling the rotating block 302 to drive the cutting disc 303 to rotate together. At this time, the rotating cutting disc 303 can pre-cut the ice surface, causing cracks to appear on the ice surface, making the ice layer easier to be broken by the impact force of the icebreaker. Coupled with the impact of the first ice-breaking hammer 206 on the ice surface, the pre-treatment effect of the ice surface can be better.

[0028] Furthermore, a hollow shell 4 is fixedly connected to one side of the cutting disc 303. A resistance wire 5 is arranged in the inner cavity of the hollow shell 4. The surface of the resistance wire 5 is fixedly connected to one side of the cutting disc 303.

[0029] It should be noted that the resistance wire 5 is located on one side of the cutting disc 303, which can play a role in heating the cutting disc 303, enabling the cutting disc 303 to have a better cutting effect through heating when cutting the ice surface. The hollow shell 4 can protect the resistance wire 5, making the resistance wire 5 not easily damaged. The resistance wire 5 can be made of copper, and copper has good thermal conductivity, enabling the temperature of the hollow shell 4 to be smoothly transmitted. The resistance wire 5 can be powered by the power supply on the ship, as long as it can meet the heating requirements, and no limitations are imposed here.

[0030] As a preferred implementation manner of this embodiment, connecting rods 6 are fixedly connected to both sides of the first ice-breaking hammer 206. The other ends of the connecting rods 6 are fixedly connected to a second ice-breaking hammer 7.

[0031] The connecting rod 6 is connected to one side of the first ice breaker 206 and can be used to connect the second ice breaker 7. The second ice breaker 7 can cooperate with the first ice breaker 206 to strike the ice together, making the striking range wider and the effect better.

[0032] Furthermore, a stop block 8 is arranged on one side of the first synchronous pulley 304, and the top of the stop block 8 is fixedly connected to the surface of the rotating block 302. The stop block 8 can limit the synchronous belt 305, making the synchronous belt 305 more stable on one side of the first synchronous pulley 304 and not prone to separating from the first synchronous pulley 304.

[0033] In this embodiment, a limiting plate 9 is arranged on one side of the hollow shell 4, and one side of the limiting plate 9 is fixedly connected to one side of the L-shaped fixing plate 301. The limiting plate 9 can limit the cutting disc 303, making the cutting disc 303 not prone to tilting on one side of the L-shaped fixing plate 301, so that cutting can be carried out stably.

[0034] In this embodiment, reinforcing rods 10 are fixedly connected to both sides of the first fixing rod 205, and the bottom of the reinforcing rods 10 is fixedly connected to the top of the second ice breaker 7. The reinforcing rods 10 can play a role in strengthening the connection of the second ice breaker 7, making the second ice breaker 7 more firm on one side of the first ice breaker 206 and not prone to breaking.

[0035] In this embodiment, a protective shell 11 is arranged on the surface of the motor 209, and the bottom of the protective shell 11 is fixedly connected to the top of the support plate 211. The protective shell 11 can play a role in protecting the motor 209, making the motor 209 not easily contaminated with moisture during use, and thus the motor 209 is not prone to damage.

[0036] When the ice-breaking device for polar icebreakers in this embodiment is in use, first, the V-shaped block 1 is welded and fixed at the bow of the icebreaker. When the icebreaker breaks the ice in the polar region, the motor 209 can be started simultaneously to drive the rotating rod 202 to rotate. The rotating rod 202 will drive the eccentric wheel 203 to perform eccentric motion, and the eccentric wheel 203 will drive the connecting frame 204 to move up and down reciprocally. At the same time, the connecting frame 204 will slide inside the hollow block 207. When the connecting frame 204 moves, it will also drive the first fixing rod 205 and the first ice breaker 206 to move together, making the first ice breaker 206 move up and down reciprocally together, so as to pre-strike the ice surface, causing cracks on the ice surface. And the impact force of the strike will generate stress inside the ice, resulting in the destruction of the internal structure of the ice, making the ice easier to be broken by the subsequent icebreaker. At the same time, the first ice breaker 206 is located above the ice surface and strikes downward, so that the ice-breaking mechanism 2 is not easily damaged by being squeezed by the icebreaker; While the motor 209 drives the rotating rod 202 to rotate, the rotating rod 202 also drives the second synchronous pulley 306 to rotate. The second synchronous pulley 306 drives the first synchronous pulley 304 to rotate together through the synchronous belt 305. The first synchronous pulley 304 drives the rotating block 302 and the cutting disc 303 to rotate. At this time, the rotating cutting disc 303 can pre-cut the ice surface, causing cracks in the ice surface, making it easier for the ice layer to be broken by the impact force of the icebreaker. Coupled with the impact of the first ice-breaking hammer 206 on the ice surface, the pre-treatment ice-breaking effect of the ice surface can be better. Among them, the cutting disc 303 is connected to the first connecting bar 201 and the icebreaker through the L-shaped fixing plate 301, so that the cutting disc 303 and the first ice-breaking hammer 206 can also move. Thus, the problem that the spiral saw is easily squeezed by the icebreaker and damaged, and only one spiral saw is used to break the ice surface, resulting in a poor ice-breaking effect, can be solved.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention.
