[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] The embodiment of the utility model discloses a shock-absorbing, noise-reducing and damping device for ships, which achieves the purpose of noise reduction and vertical shock absorption through a base plate material with a foamed rubber interlayer and a reinforced damping element. Through the design of compression springs installed at the head end and the end of the base plate material, on the one hand, horizontal damping and shock absorption are achieved, and on the other hand, it is convenient to protect the edges of the shock-absorbing, noise-reducing and damping device, and the compression amount of the compression spring and the movably arranged head end can be used to adjust the size to adapt to changes in the size of the installation space.

[0025] For details, please refer to Figure 1-4 As shown, the technical solution of the embodiment of the utility model includes a base plate 10 , a head end 20 and a compression spring 30 .

[0026] The base plate material 10 includes a first panel 11 , a second panel 12 and a foam rubber layer 13 .

[0027] The first panel 11 and the second panel 12 are made of the same material, which is an aluminum alloy plate, which is lightweight and helps to reduce the weight of the shock-absorbing and noise-reducing damping device. In some examples, a carbon fiber plate with high strength and lightness can also be selected. The first panel 11 and the second panel 12 act as a protective layer.

[0028] The foam rubber layer 13 is sandwiched between the first panel 11 and the second panel 12, and the top and bottom of the foam rubber layer 13 are respectively bonded to the first panel 11 and the second panel 12 through the adhesive layer 16. The material used for the adhesive layer 16 is preferably waterproof glue, which plays a role of bonding and connection on the one hand, can improve the overall stability of the base plate 10, and also plays a role of waterproofing on the other hand.

[0029] The foam rubber layer 13 is a foam butyl rubber layer, which has the functions of supporting, shock absorption, noise reduction and damping. The volume occupancy rate of the foam cells in the foam rubber layer 13 is 10-40%, preferably 15-25%.

[0030] In order to further improve the shock absorption and damping effect, a reinforcement damping element 14 is further embedded in the foam rubber layer 13. The top and bottom of the reinforcement damping element 14 are bonded to the first panel 11 and the second panel 12 through the adhesive layer 14.

[0031] Specifically, the enhanced damping element 14 includes a layered cavity body 141 and a particle damping element 142. The layered cavity body 141 is a rectangular structure and is filled in the space surrounded by the first panel 11, the second panel 12 and the foam rubber layer 13. The layered cavity body 141 is made of aluminum alloy material, and its interior is divided into a plurality of layered cavities, each of which is filled with the particle damping element 142, and the particle damping element 142 occupies 60 to 90% of the volume of the layered cavity 141. Through the design of multiple layered cavities, the particle damping elements 142 are arranged in layers and in an orderly manner, which is conducive to improving the damping and shock absorption effect.

[0032] The particle damping element 142 includes an elastic bag 1421 and damping particles 1422. The elastic bag 1421 is a soft bag made of rubber material, which is easy to change shape. The damping particles 1422 are installed in the elastic bag 1421. The damping particles 1422 are spheres, which are made of aluminum alloy balls and are coated with a rubber layer. In some embodiments, the damping particles 1422 can also be ABS balls with a rubber layer coated on the surface, and the diameter of the damping particles 1422 is 3 to 5 mm.

[0033] The head end 20 is a rectangular cavity structure made of aluminum alloy, and the end of the head end 20 facing the base plate is an open end. The inside of the head end 20 is provided with 4 or 8 sliders (not shown in the figure) near the ribs, and the outside of the first panel 11 and the second panel 12 is provided with slide grooves (not shown in the figure) that cooperate with the sliders. The head end 20 is slidably sleeved on the two ends of the base plate 10 through the cooperation of the sliders and the slide grooves, and the distance between the head end 20 and the end of the base plate 10 is changed, thereby changing the size of the entire shock-absorbing and noise-reducing damping device to meet the installation requirements of spaces of multiple sizes and improve practicality.

[0034] The four corners of the end of the base plate 10 are provided with at least one guide column 15, preferably, the guide column 15 is fixed on the first panel 11 or the second panel 12, and the first panel 11 and the second panel 12 can provide sufficient strength support for the guide column 15. The guide column 15 is arranged along the length direction of the base plate, that is, arranged horizontally.

[0035] A compression spring 30 is sleeved on each guide post 15. One end of the compression spring 30 facing the base plate 10 is fixedly connected to the base plate 10 (specifically, the first panel 11 or the second panel 12) to prevent the compression spring from sliding off the guide post 15; one end of the compression spring 30 facing the head end 20 is a free end.

[0036] When the end of the sealing head 20 is at the maximum distance from the end of the base plate 10 , the compression spring 30 is in a free extension state.

[0037] The length of the guide column 15 is greater than the length of the compression spring 30 when it is at the maximum compression, which can prevent the compression spring 30 from being damaged due to being at the maximum compression for a long time; the length of the guide column 15 is also smaller than the length of the compression spring 30 in a freely extended state, ensuring that when the distance between the head end 20 and the base plate 10 is reduced, the compression spring 30 can play an effective shock-absorbing role, thereby improving the shock-absorbing performance of the shock-absorbing and noise-reducing damping device in the horizontal direction.

[0038] The ship vibration reduction and noise reduction damping device according to the embodiment of the utility model has the following advantages:

[0039] 1. Through the design of foam rubber layer and enhanced damping element, it has excellent noise reduction and shock absorption performance;

[0040] 2. Through the design of compression spring, the shock absorption performance in the horizontal direction is realized;

[0041] 3. Through the design of the head end, the protection of the base plate is improved, and the distance between the end of the base plate can be adjusted to adapt to the changes in the size of the installation area and improve practicality.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
