Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polar icebreaker, in particular to a polar icebreaker fender buffer structure. BACKGROUND

[0002] The polar icebreaker fender is a buffer device installed on the icebreaker, mainly used to reduce the impact force when the ship body collides with the ice layer or other ships, protect the ship body and reduce damage. The polar icebreaker fender is usually composed of an outer steel structure and an inner elastic structure.

[0003] Due to the extremely cold and complex polar environment, the collision of ships with ice layers or other ships is inevitable. The design of the fender can effectively reduce the damage caused by such collisions and protect the ship body from serious damage, but there are still the following defects. Although the traditional icebreaker has a certain ice layer penetration ability, when it encounters an iceberg, it often cannot effectively reduce the damage of the collision to the ship structure due to the lack of effective buffering and energy absorption measures, resulting in a shortened service life and increased maintenance cost.

The elastic deformation absorption of the rubber pad reduces the direct impact on the fender body, effectively protecting the fender body from damage caused by excessive impact force.

[0025] 4. The polar icebreaker fender buffer structure converts electrical energy into thermal energy by setting a heating film, evenly heating the pad. When the pad is heated to a certain temperature, it will transfer the heat to the fender body, causing the temperature of the fender body to increase, thereby effectively isolating and reducing the impact of the external ambient temperature on the fender body.

[0038] Please refer to Figures 1-7As shown, the present invention provides a technical solution:

[0039] A polar icebreaker fender buffer structure includes a connecting frame 2, a fender frame 3 is fixedly connected to the top of the connecting frame 2, a fender body 4 is fixedly connected to the inner side of the fender frame 3, a plurality of connecting rings 10 are fixedly connected to the inner wall of the fender body 4, a pad 7 is fixedly connected to the inner wall of the connecting ring 10, a plurality of evenly distributed fixing plates 11 are provided on the inner wall of the pad 7, and a fender block 1 is fixedly connected to both sides of the fender body 4;

[0040] The inner layer buffer assembly 8 is provided on the inner wall of the plurality of fixed plates 11 and is used for secondary buffering;

[0041] A heating component is provided on the circumferential outer wall of the backing plate 7 and is used to increase the temperature of the fender body 4;

[0042] Furthermore, the heating assembly includes a heating film 6 or a heating wire bonded to the outer circumferential wall of the pad 7, preferably a heating film 6. The function of the heating film 6 is to uniformly heat the pad 7 by converting electrical energy into thermal energy. When the pad 7 is heated to a certain temperature, the heat will be transferred to the fender body 4, so that the temperature of the fender body 4 increases, thereby effectively isolating and reducing the influence of the external ambient temperature on the fender body 4.

[0043] A cleaning assembly 5 is slidably arranged on the top of the fender frame 3 and is used to clean the fender body 4;

[0044] Furthermore, the cleaning assembly 5 includes a cleaning plate 501 slidably connected to the top of the fender frame 3, a cavity is provided in the cleaning plate 501, a liquid inlet 502 is provided on one side of the cleaning plate 501 and at the center, and a plurality of liquid outlets 503 are provided at the bottom of the cleaning plate 501, the top of the fender frame 3 is symmetrically provided with grooves, a threaded rod 31 is rotatably provided inside the groove on one side, a waterproof motor 32 is provided on one side of the fender frame 3, the output end of the waterproof motor 32 is fixedly connected to one end of the threaded rod 31, and sliders 504 are fixedly connected at both ends of the cleaning plate 501, the slider 504 is slidably set in the groove, a threaded hole 5041 is provided in the middle of the slider 504, and the slider 504 is threadedly connected to the threaded rod 31 through the threaded hole 5041. When the fender body 4 needs to be repaired and cleaned, the detergent is injected into the liquid inlet 502, and the detergent will flow out of the cavity from the plurality of liquid outlets 503. The liquid flows evenly onto the outer wall of the fender body 4, and the forward and reverse rotation of the threaded rod 31 is controlled by the waterproof motor 32. The slider 504 drives the cleaning plate 501 to reciprocate along the outer wall of the fender body 4. The scraping effect generated when the plate surface contacts the outer wall of the fender body 4 effectively removes foreign matter and stains on the outer wall.

[0045] It is worth noting that the cleaning agents used in this technical solution are all biodegradable materials, which reduces water pollution. In addition, the waterproof motor 32 can be powered by the ship's onboard energy storage system, reducing energy consumption.

[0046] Furthermore, the surface of the fender body 4 is coated with an anti-freezing layer, which can reduce ice adhesion, reduce cleaning frequency and maintenance costs.

[0047] The outer layer buffer assembly 9 is provided on the circumferential outer wall of the pad 7 and is used to provide preliminary buffering for the fender body 4 .

[0048] Fender blocks 1 are welded on both sides of the fender body 4. First, the connecting frame 2 is installed on the bow part of the front end of the icebreaker. When the icebreaker is breaking ice, the fender frame 3 has the function of initially alleviating the impact force. When the icebreaker encounters ice, the reverse impact force generated by the ice surface first acts on the fender frame 3. The weakened impact force then penetrates into the fender body 4 made of strong steel material, and the impact force is weakened again by the outer buffer component 9. The remaining impact force will be absorbed by the internal inner buffer component 8 through the pad 7, forming an efficient impact force conduction and absorption system, ensuring that the icebreaker hull structure can be effectively protected from damage during icebreaking operations.

[0049] In the present invention, the inner walls of the plurality of fixed plates 11 are provided with inner layer buffer components 8 for secondary buffering, and the inner layer buffer components 8 include a plurality of buffer rings 801 fixed to the inner wall of the fixed plate 11 by bolts, and the inner wall of the buffer ring 801 is fixed with a plurality of evenly distributed buffer blocks 803 by bolts, and a buffer column 804 is welded to one end of the buffer block 803, and a fender spring 805 is sleeved on the outer side of the buffer column 804, and one end of the fender spring 805 is fixed to the bottom end of the buffer block 803, and the other end is fixed to the outer side of the fixed ring 807. During the contraction movement, the fender spring 805 will also undergo a certain amount of deformation, and the fender spring 805 can absorb the impact force while also buffering The block 803 is reset to the initial state where it did not absorb the impact force. The fender spring 805, through its own elastic action, not only effectively absorbs the impact force applied by the pad 7, but also enables some components of the inner buffer assembly 8 to return to their initial state. A fixing ring 807 is welded at one end of the buffer column 804, and a buffer shell 802 is welded on one side of the fixing ring 807. A plurality of buffer grooves 806 are provided on the outer side of the buffer shell 802. The impact force transmitted from the pad 7 will cause the plastic deformation of the buffer ring 801 to cause the plurality of buffer blocks 803 to contract synchronously in the direction of the fixing ring 807. Finally, the impact force is transmitted and dispersed to the fixing ring 807, thereby achieving the effect of shock absorption and buffering.

[0050] Furthermore, the buffer block 803 and buffer shell 802 are embedded with an array of piezoelectric ceramic discs, distributed radially. The electrical energy generated by the piezoelectric ceramic discs during a collision is connected to the shipboard energy storage system, which is electrically connected to the heating component. When the fender is impacted, the inner buffer component 8 transmits the impact force to the piezoelectric ceramic discs, causing them to compress or bend. This converts the mechanical energy generated by the collision into electrical energy, which is stored in the shipboard energy storage system. The specific energy storage method can be based on existing technologies and is not described here. The shipboard energy storage system can also power the heating component, reducing energy consumption.

[0051] As a preferred implementation of this embodiment, the outer buffer assembly 9 includes a plurality of evenly distributed shells 901 fixed to the circumferential outer wall of the pad 7 by bolts. Two slides are provided on the top of the shell 901, and a shock-absorbing column 903 is slidably connected in the slide. Rubber air springs 904 are provided on the outside of the two shock-absorbing columns 903. One end of the rubber air spring 904 is clamped on the bottom of the connecting plate 905, and the other end is fixed to the top of the shell 901. The rubber air spring 904 can effectively absorb and buffer the vibration of external impact force through its good elasticity and energy storage characteristics. A connecting plate 905 that contacts the inner wall of the fender body 4 is welded to the top of the shock-absorbing column 903. A rubber pad 902 bonded to the circumferential outer wall of the pad 7 is provided in the shell 901. The external impact force is transmitted to the shock-absorbing column 903 through the connecting plate 905. The shock-absorbing column 903 moves downward in the slide and contacts the rubber pad 902. The rubber pad 902 deforms to absorb the impact force, thereby achieving preliminary shock absorption of the impact force.

[0052] The shock-absorbing column 903 can adopt a hydraulic damper, a pneumatic damper, a spring damper, etc., preferably a pneumatic damper. The pneumatic damper absorbs energy by gas compression and expansion, has a softer buffering speed than the hydraulic damper, and is more suitable for colder environments.

[0053] Furthermore, shock absorber 903 is a linear electromagnetic damper, with a permanent magnet embedded in the piston head. A multi-layered annular copper coil is fixed to the inner wall of the shock absorber's shell. Its output is electrically connected to the onboard energy storage system, which also powers other equipment. The energy storage method uses existing technology and will not be detailed here.

[0054] When the polar icebreaker fender buffer structure of this embodiment is in use, the fender frame 3 has the function of initially alleviating the impact force;

[0055] When the icebreaker encounters ice, the reverse impact force generated by the ice surface first acts on the fender frame 3. The weakened impact force then penetrates into the fender body 4 made of strong steel material. The external impact force is transmitted to the shock absorber column 903 through the connecting plate 905. The shock absorber column 903 moves downward in the slide and contacts the rubber pad 902.

[0056] At this time, the rubber pad 902 deforms to absorb the impact force, and the remaining impact force will cause the multiple buffer blocks 803 to shrink synchronously toward the fixing ring 807 through the plastic deformation of the buffer ring 801 inside the pad 7. Finally, the impact force is transmitted and dispersed to the fixing ring 807, forming an efficient impact force transmission and absorption system, ensuring that the icebreaking ship structure can be effectively protected from damage during icebreaking operations.

[0057] The mechanical energy generated during the collision can be converted into electrical energy through the linear electromagnetic damper and the piezoelectric ceramic array embedded in the buffer block 803 and the buffer shell 802, stored in the shipboard energy storage system, and used to power other equipment, reducing energy consumption.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
