Description

Technical Field

[0001] This utility model belongs to the field of ship cabin technology, and more specifically, it relates to a ship cabin room structure that improves noise reduction function. Background Technology

[0002] The conventional cabin noise reduction solution uses ordinary floating deck material on the steel deck, the composite rock wool wall panels have no rubber pads at the bottom, the composite rock wool ceiling installation nodes are rigid connections, and the steel bulkhead has no rock wool, which leads to excessive cabin noise measurements and the overall performance of the ship failing to meet requirements.

[0003] In the prior art, there is a technology entitled "Ship Cabin Module" with publication (announcement) number "CN101426680A", which provides a ship cabin module for forming unit cabins such as galleys on the hull. The ship cabin module (1) of the present invention is moved from the outside of the hull into the inside of the hull, and a unit cabin (11) consisting of a defined space is formed inside the hull. The unit cabin (11) is composed of the following components: a floor surface (12) made of steel plate, and a wall surface (13) and a ceiling surface (14) composed of multiple fireproof plates (131, 141) assembled on the floor surface (12). The floor surface (12) is brought into contact with the deck of the hull, and the deck and floor surface (12) of the hull are fixed and installed inside the hull. Existing technology includes a technology entitled "A Ship's Cabin Module" with publication (announcement) number "CN119682917A". This technology discloses a ship's cabin module, relating to the field of ship cabins, including a cabin roof with four rectangularly distributed sidewalls at its bottom; a floor located at the bottom of the sidewalls for supporting the sidewalls; and four connecting structures installed on top of the floor in a rectangular arrangement for connecting the cabin roof, floor, and sidewalls. The connecting structures consist of a support frame, support rods, a first fixed blade sleeved on the support rods, and a second fixed blade sleeved on the support rods. Both the first and second fixed blades can rotate around the support rods. This invention, by inflating and deflating a driving airbag, can lock or unlock the first and second fixed blades. After unlocking, the first and second fixed blades can rotate around the support rods and change their positions, thereby allowing the sidewalls that need to be removed to be removed individually without removing other components of the cabin module. This reduces the workload of workers and saves time.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ship cabin room structure with improved noise reduction function that is simple in structure, can effectively improve the sound insulation effect of ship cabin rooms, achieve noise reduction, and improve the comfort of ship cabin rooms.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a ship cabin room structure that improves noise reduction function. A side wall is set between the upper deck and the lower deck. A composite floating deck covering layer is set on the lower deck. A bulkhead panel is set on the composite floating deck covering layer. A rubber pad is set between the bulkhead panel and the composite floating deck covering layer. A first rock wool layer is set on the inner wall of the side wall.

[0008] The inner wall of the bulkhead panel is fitted with a composite rock wool ceiling near the top.

[0009] The bulkhead panels are arranged vertically on the composite floating deck covering layer, and the composite rock wool ceiling is parallel to the composite floating deck covering layer.

[0010] The inner wall of the side enclosure is provided with a fixed angle iron near the upper part, and the fixed angle iron is connected to the upper part of the bulkhead plate through an elastic fastener.

[0011] The composite floating deck is covered with pads, and rubber pads are placed on the pads. The rubber pads are connected to the lower part of the bulkhead panels.

[0012] The composite rock wool ceiling is connected to the inner wall of the cabin wall panel near the upper part by elastic fasteners.

[0013] The lower deck is equipped with water-blocking flat iron bars, which are located on the side of the composite floating deck lining layer.

[0014] The composite floating deck dressing layer consists of, from top to bottom, a vinyl floor layer, a leveling dressing layer, a first galvanized steel plate layer, a first damping coating layer, a second galvanized steel plate layer, a second damping coating layer, a second galvanized steel plate layer, a second rock wool layer, a restraint layer, and a third damping coating layer.

[0015] The constraint layer is a structure made of solvent-free epoxy resin material.

[0016] A kickboard is installed on the inner wall of the bulkhead panel near the lower part.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The ship cabin structure with improved noise reduction function described in this utility model includes a bulkhead room located between the upper and lower decks. Side walls are installed between the upper and lower decks, isolating adjacent side walls into separate bulkhead rooms. A composite floating deck lining layer is installed on the lower deck. This composite floating deck lining layer improves noise reduction performance in the ground direction, preventing ground noise from reaching the bulkhead room. Bulkhead panels are installed on the composite floating deck lining layer, with rubber pads between the bulkhead panels and the composite floating deck lining layer. The rubber pads prevent friction noise from the groove between the composite rock wool bulkhead panels and the composite floating deck lining layer. A first rock wool layer is installed on the inner wall of the side walls, preventing lateral noise from reaching the bulkhead room. Through structural improvements in multiple areas, the sound insulation effect of the bulkhead room is effectively improved, achieving effective noise reduction. The noise level of the cabin meets the requirements after measurement. Attached Figure Description
