Description

Technical Field

[0001] This utility model belongs to the field of sound-absorbing and sound-insulating panel technology, and in particular relates to a composite vibration-damping and sound-absorbing panel structure for ships. Background Technology

[0002] With the rapid development of the shipbuilding industry, the requirements for acoustic comfort and structural safety of ship cabins are increasing. During operation, ships are constantly subjected to vibrations and noise generated by the main engine, propeller, and wave impact. At the same time, the humid and corrosive environment inside the cabins, such as salt spray, poses a severe challenge to the durability of materials. Therefore, sound-absorbing and vibration-damping panel structures have become an important part of ship bulkheads and decks, and their performance directly affects the acoustic environment quality and structural reliability of the ship.

[0003] Existing sound-absorbing and insulating panels mostly adopt a one-piece molded composite panel structure, typically composed of a metal panel, an intermediate damping layer, and porous sound-absorbing material. However, due to the long-term exposure of ships to a corrosive atmosphere with high humidity and high salinity, the surface of the metal panel is prone to chemical or electrochemical corrosion. Corrosion not only reduces the strength and flatness of the panel but also gradually propagates inward, affecting the internal materials. Furthermore, in terms of installation, sound-absorbing and insulating panels are mostly connected to the hull structure by welding. The welding process requires manual positioning, which is prone to errors leading to misalignment of the welded position.

[0004] To address these issues, we offer a composite vibration damping and sound-absorbing panel structure for ships. Utility Model Content

[0005] The purpose of this utility model is to provide a composite shock-absorbing and sound-insulating plate structure for ships. By combining the disassembly mechanism and the first threaded hole, the problems of the inability to replace the panel and poor welding positioning in the existing sound-absorbing and sound-insulating plate structure during use are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a composite shock-absorbing and sound-insulating panel structure for ships, comprising a glass fiber reinforced polymer backplate, a foamed aluminum plate on top of the glass fiber reinforced polymer backplate, and a metal panel on top of the foamed aluminum plate; a disassembly mechanism is provided on top of the glass fiber reinforced polymer backplate, the disassembly mechanism comprising a first threaded hole on top of the foamed aluminum plate, a second threaded hole on top of the metal panel, and a sealing plate disposed inside the second threaded hole; a positioning mechanism is provided at the bottom of the metal panel, the positioning mechanism comprising a positioning plate on top of the foamed aluminum plate, and third threaded holes respectively on the positioning plate and the top of the foamed aluminum plate.

[0008] The present invention is further configured such that the disassembly mechanism includes a groove formed on the top of the metal panel, and a fixing cylinder fixedly connected to the bottom of the groove.

[0009] The present invention is further configured such that the disassembly mechanism includes a connecting rod fixedly connected to the top of the sealing plate and a movable groove formed on the top of the metal panel.

[0026] Example 1

[0027] Please see Figures 1-5This utility model relates to a composite vibration damping and sound-absorbing panel structure for ships, comprising a glass fiber reinforced polymer backing plate 1. The glass fiber reinforced polymer backing plate 1 has good corrosion resistance and lightweight properties. A foamed aluminum plate 2 is provided on the top of the glass fiber reinforced polymer backing plate 1. The foamed aluminum plate 2 serves as an intermediate layer, combining lightweight, high strength, and good sound absorption performance, effectively absorbing and dispersing vibration and noise energy. A metal panel 3 is provided on the top of the foamed aluminum plate 2, with its bottom in close contact with the foamed aluminum plate 2. The metal panel 3 serves as an outer panel, providing aesthetic appeal, wear resistance, and impact protection. A disassembly mechanism 4 is provided on the top of the glass fiber reinforced polymer backing plate 1. The disassembly mechanism 4 facilitates the disassembly and replacement of the metal panel 3, avoiding the inconvenience and corrosion risks associated with welding fixation. The disassembly mechanism 4 includes a section located on the top of the foamed aluminum plate 2. The metal panel 3 has a first threaded hole 41 and a second threaded hole 42 at the top. The first threaded hole 41 and the second threaded hole 42 are used to bolt the metal panel 3 to the aluminum foam board 2. A sealing plate 45 is set inside the second threaded hole 42 to seal the second threaded hole 42 and prevent corrosive media from entering. The bottom of the metal panel 3 is provided with a positioning mechanism 5. The positioning mechanism 5 ensures the precise alignment and installation between multiple sound insulation panels and reduces the need for manual positioning. The positioning mechanism 5 includes a positioning plate 51 at the top of the aluminum foam board 2. The bottom of the positioning plate 51 is in close contact with the aluminum foam board 2. The positioning plate 51 provides a mechanical positioning reference to ensure the accurate installation position of the panel. A third threaded hole 52 is set at the top of the positioning plate 51 and the aluminum foam board 2 respectively. The third threaded hole 52 is used to bolt adjacent sound insulation panels.

[0028] Example 2

[0029] Please see Figures 1-5Based on Embodiment 1, the disassembly mechanism 4 further includes a groove 43 formed on the top of the metal panel 3, a fixed cylinder 44 fixedly connected to the bottom of the groove 43, a connecting rod 46 fixedly connected to the top of the sealing plate 45, and a movable groove 49 formed on the top of the metal panel 3. The movable groove 49, the second threaded hole 42, and the groove 43 are all connected. The disassembly mechanism 4 also includes a spring 47 set on the top of the metal panel 3. The spring 47 and the movable plate 48 are both located inside the fixed cylinder 44. The bottom of the spring 47 is fixedly connected to the bottom of the fixed cylinder 44, and the movable plate 48 is fixedly connected to the top of the spring 47. The end of the connecting rod 46 away from the sealing plate 45 passes through the interior of the fixed cylinder 44 and is rotatably connected to the movable plate 48 through a bearing. The fixed cylinder 44 provides installation space for the spring 47 and the movable plate 48. The connecting rod 46 connects the sealing plate 45 and the movable plate 48 and transmits operating force. Spring 47 provides a restoring force to keep the sealing plate 45 in a normally closed state. Movable plate 48 moves in a slide groove via a slider to control the lifting and lowering of connecting rod 46 and sealing plate 45. Movable groove 49 allows connecting rod 46 to move up and down. Positioning mechanism 5 also includes a slot 53 opened at the bottom of metal panel 3. The slot 53 is adapted to the size of positioning plate 51. The slot 53 cooperates with positioning plate 51 to enhance the positioning stability of metal panel 3. Metal panel 3 and positioning plate 51 are in close contact. A slider is fixedly connected to one side of movable plate 48. A slide groove is provided on one side of slider. The slide groove is opened inside one side of fixed cylinder 44. The size of slide groove is adapted to slider. Shock-absorbing rubber plate 6 is fixedly connected to the bottom of foam aluminum plate 2. Shock-absorbing rubber plate 6 is located between foam aluminum plate 2 and back plate to further absorb and buffer vibration and improve the overall shock absorption effect. The bottom of shock-absorbing rubber plate 6 is fixedly connected to glass fiber reinforced polymer back plate 1.

[0030] The working principle of this utility model is as follows: First, the glass fiber reinforced polymer backing plate 1 is welded to the hull structure. When installing the second sound insulation plate, the adjacent sound insulation plates are fixedly connected by bolts through the cooperation of the positioning plate 51 and the third threaded hole 52, achieving precise alignment without the need for manual positioning assistance.

[0031] When it is necessary to install or replace the metal panel 3, pull the connecting rod 46 upwards to move the sealing plate 45 out of the second threaded hole 42, and rotate the connecting rod 46 to open the second threaded hole 42. Position the metal panel 3 using the positioning plate 51, and then use bolts to connect and fix the metal panel 3 to the foam aluminum plate 2. After completion, release the connecting rod 46, and the spring 47 pushes the movable plate 48 to reset, causing the sealing plate 45 to re-close the second threaded hole 42, preventing corrosive media from entering. If the metal panel 3 is damaged, it can be replaced individually without dismantling the entire structure, significantly reducing maintenance costs and time. Simultaneously, the composite structure of the foam aluminum plate 2 and the shock-absorbing rubber plate 6 effectively absorbs and disperses vibration and noise energy, improving the acoustic comfort and structural safety of the ship's cabin.
