Description

Technical Field

[0001] The utility model relates to the technical field of ship sound insulation technology, in particular to a sound insulation and noise reduction board for yachts. Background Art

[0002] When a yacht is traveling on the water, hull structural noise and hull vibration are inevitable phenomena. Due to the large external noise, when it is necessary to install a sound insulation and noise reduction board, the currently used sound insulation board, for example, a composite sound insulation board disclosed in patent publication number CN204547236U, is provided with a multi-layer composite structure to achieve a better noise reduction effect.

[0003] When the above device is installed, the chamfered part is made of two such sound insulation boards pressed together, and sealant is applied to the gap between the two sound insulation boards to complete the installation and sealing. However, when this kind of sound insulation board is installed on a yacht, unlike buildings fixed on the ground, the yacht often moves in the water and often produces certain structural deformations. This will cause the two partitions to easily form gaps in the corner area, and the noise will be transmitted through these gaps. Therefore, it is usually difficult for the yacht noise reduction process to reach a very ideal range. Excessive vibration of the hull will also cause hard friction between adjacent sound insulation boards to generate additional noise. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a sound insulation and noise reduction board for yachts to solve the problem that gaps are easily formed in the corner area.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sound insulation and noise reduction plate for yachts comprises a first partition, a second partition and a connecting piece, wherein the connecting piece comprises a sound insulation pad, a first clamp is fixedly connected to the left side of the sound insulation pad, the first partition is inserted into the first clamp, a second clamp is fixedly connected to the bottom of the sound insulation pad, the second partition is inserted into the second clamp, and a triangular lining is fixedly connected to the inner side of the sound insulation pad.

[0007] Preferably, the triangular lining includes a folding piece, a first fixing piece is fixedly connected to the left side of the folding piece, the first fixing piece is fixedly connected to the first partition by bolts, and a second fixing piece is fixedly connected to the bottom of the folding piece, and the second fixing piece is fixedly connected to the second partition by bolts.

[0008] Preferably, the sound insulation pad is made of flexible material.

[0009] Preferably, sound insulation structures are provided in both the first partition plate and the second partition plate.

[0010] In summary, the beneficial effects of the present utility model are as follows: A sound insulation and noise reduction board for a yacht provided by the present utility model connects the chamfered joints of two sound insulation boards, namely the first partition board and the second partition board, by using a connecting piece. The main structure of the connecting piece is a deformable sound insulation pad, and a certain degree of sound absorption and chamfer beautification effects are achieved through a triangular inner lining. In this way, when the first partition board and the second partition board generate certain deformations during the movement of the yacht, there will be no sound leakage gaps, and the sound insulation effect is better. Since the connecting piece at the joint can deform, the first partition board and the second partition board will not generate additional noise due to friction, so that the sound insulation board and the sound insulation structure have a better noise reduction effect when used on the yacht.

The second partition 2 is inserted into the second clamping piece 303. A triangular inner lining 4 is fixedly connected to the inner side of the sound insulation pad 301.

[0016] The first partition 1 and the second partition 2 themselves have a sound insulation structure and play a sound insulation role. When used on a yacht, they are used in cooperation with the connecting piece 3. The sound insulation pad 301 in the connecting piece 3 is made of a flexible material. A porous structure can be arranged on its inner side for noise reduction and sound absorption, and a smooth surface structure can be arranged on its outer side to effectively block the propagation of noise. The first partition 1 and the second partition 2 are respectively clamped at the first clamping piece 302 and the second clamping piece 303 and fixed with bolts. In this way, the first partition 1, the second partition 2 and the connecting piece 3 form a sound insulation whole, and a certain degree of sound absorption and beautifying chamfering effects are achieved through the triangular inner lining 4. Moreover, the sound insulation pad 301 in the connecting piece 3 can undergo flexible deformation.

The first fixing piece 402 and the second fixing piece 403 are respectively fixed to the first partition 1 and the second partition 2 by bolts. The folding piece 401 is similar to the folding structure of an accordion. Together with the first fixing piece 402 and the second fixing piece 403, it blocks the sound insulation pad 301, further improving the sound insulation effect at the sound insulation pad 301, and its own folding structure similar to an accordion can allow large deformations.

[0019] Sound insulation structures are arranged in both the first partition 1 and the second partition 2. The sound insulation structures arranged inside the first partition 1 and the second partition 2 are sound insulation boards, which can play a sound insulation role. The sound insulation boards and the sound insulation structures are existing technical structures and will not be elaborated.

[0020] Working principle: When in use, the first partition 1 and the second partition 2 are respectively clamped at the first clamping member 302 and the second clamping member 303, and the triangular inner lining 4 is fixed by bolts. The first partition 1 and the second partition 2 are fixed in the engine room of the yacht by fixing members, and the installation can be completed. The first partition 1 and the second partition 2 are respectively clamped at the first clamping member 302 and the second clamping member 303. In this way, the first partition 1, the second partition 2 and the connecting member 3 form a sound insulation whole, and a certain degree of sound absorption and chamfer beautification effect are achieved through the triangular inner lining 4. Moreover, the sound insulation pad 301 in the connecting member 3 can undergo flexible deformation.
