Abstract

PURPOSE:To effectively disconnect the vibration of a main engine and the noise from an engine room by supporting an upper structure as hull living quarters against a hull structure through a vibration-proof mechanism. CONSTITUTION:A support frame 2 is provided at a hull 5 as a lower structure and an upper structure 1 as living quarters is supported through a vibration- proof mechanism 3 such as oil-sealing damper. The piping and wiring against the living quarters 1 are performed through a flexible hose. As a result, the vibration coming from a main engine and the noise of an engine room can be disconnected and the environment of the living quarters can be improved.

Description

Detailed Description of the Invention ``Object of the Invention'' The present invention relates to living quarters on a ship, and uses vibrations caused by the main diesel engine and noise from the engine room to adversely affect the work or life of crew members, the ship structure, or equipment, or to cause accidents. The aim is to create a living quarters for ships that will never come.

Industrial Application Fields Living quarters on ships Conventional technology The living quarters on ships are attached directly to the hull, and countermeasures against vibrations include ■ reinforcing the hull to increase its rigidity; ■ strengthening the main engine. Measures are being taken to reduce the vibrational force of the engine by equipping the engine with a balancer, etc., and to cancel it out by applying vibrations that are in the opposite phase to the vibrations of an electric vibrator. Measures such as vibration settings and installation of sound insulating materials are being taken.

Problems to be Solved by the Invention However, each of the above-mentioned measures still has its own problems. In other words, ■ causes an increase in the weight of the steel material, and it is impossible to erase the camera over the entire area, and ■■ also causes an increase in equipment costs, and moreover, It is not an effective facility and cannot cope with complex vibration changes such as those caused by the loading condition of a ship. (■) has the disadvantage of becoming a source of vibration if the hull's vibration frequency and design do not match, and (■) requires installing sound insulating material over a vast area, which inevitably increases costs considerably. . Furthermore, there is no definitive solution to the rolling, pitching, or other shaking of the ship's hull, and it is often impossible to analyze the vibrations of the complex superstructure in detail, making it impossible to provide an effective solution.

[Structure of the Invention] Means for Solving the Problems A living quarters in a ship, characterized in that the living quarters are constructed as a single unit, and the living quarters are supported on the hull via a vibration isolating mechanism.

Vibration or noise in the main engine or engine room of the working hull is transmitted to the accommodation area via the vibration isolation mechanism, which significantly damps the vibration or noise.

Therefore, it will not cause deformation or accidents to the crew's work or life, or to the ship's structure or equipment such as living quarters.

EXAMPLE To further explain the present invention as described above, the present invention completely separates the engine room, which is the source of vibration and noise, from the accommodation area (superstructure), thereby preventing solid propagation of vibration and noise. To explain the specific embodiment of this system, which is shown in the attached drawings, as shown in Figures 1 and 2, a support frame 2 is provided on the hull 5, which is the lower structure, and the structure is constructed as an independent single body. The formed living area 1 is supported via a vibration isolating mechanism 3 such as an oil-sealed damper, and the piping and wiring for such living area 1 are all connected to flexible hoses 4 as shown in Fig. 3. It is connected to the engine room of the lower structure 5. Note that a rubber sheet 6 is provided between the living area 1 and the lower structure 5 as described above! As shown in Fig. 2, the living quarters 1 are suspended symmetrically in the ship's width direction using flexible wires or other suspending materials 7, as shown in Figure 2. It is preferable to form a hanging stop.

That is, it is clear that the flexible hanging material 7 such as the wire described above is also a vibration isolating mechanism, and together with the vibration isolating mechanism 3 such as an oil-sealed damper, the living area 1 has at least several vibration isolators. Since it is supported by the hull lower mechanism 5 via a mechanism, vibrations and noise caused by the main engine, engine room, etc. as vibration and noise sources are not transmitted to the living area at least as solid propagation.
Therefore, it is possible to provide a living area 1 in which hardly any vibration or noise is propagated.

``Effects of the Invention'' According to the present invention as explained above, the accommodation area and the lower structure of the hull are supported via a vibration isolating mechanism, and vibrations and noise in the main engine and engine room are effectively isolated, and the crew members can enjoy their work or work. This is an invention that has great industrial effects, since it does not have any negative impact on people's daily lives, nor does it cause any negative impact or accidents on living areas or equipment.
