Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a separated ship vibration-damping deck. Background Art

[0002] Ship vibration has always been a key issue in ship design, which can be divided into two categories: total vibration and local vibration. Excessive ship vibration can cause fatigue damage to local structures, equipment failures, and affect the health of crew members. The ship deck is a platform for equipment installation and crew operations and living. Effective control of deck vibration is an important measure to ensure the habitability, safety, and functionality of the ship.

[0003] Special measuring equipment on the deck of special operation ships has very high requirements for vibration control of the installation deck. At the same time, the equipment drive unit itself is the excitation source. Therefore, the vibration isolation capability of conventional ship deck structure design cannot meet the measurement accuracy requirements of the measuring equipment.

[0004] In order to reduce the local vibration at the equipment base of the hull deck and ensure the normal installation and use requirements of the equipment, the existing technology generally installs elastic supports at the equipment base or increases the stiffness of the deck structure below the equipment to reduce vibration.

[0005] The disadvantages of the prior art are as follows:

[0006] 1. Some devices do not support the installation of elastic supports;

[0007] 2. By increasing the rigidity of the deck, the use of materials is increased, and there is usually a limitation of limited space under the deck;

[0008] 3. For the overall equipment including the driving unit (excitation source) and the measuring unit which has very high requirements on deck vibration, the positions of the two are very close, and simply increasing the deck stiffness is not effective. Summary of the invention

[0009] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a separated ship vibration-damping deck.

[0010] The present invention solves the above technical problems through the following technical solutions:

[0011] A detachable ship vibration-damping deck comprises a deck main body and a deck detaching part; the deck main body is provided with a hollow part, and the deck detaching part is arranged in the hollow part; a supporting part is fixedly arranged at the bottom of the deck detaching part; a first base for supporting equipment parts with a vibration source is fixedly arranged on the deck main body; and a second base for supporting equipment parts without a vibration source is fixedly arranged on the deck detaching part.

[0012] Furthermore, the deck main body and the deck separation part are located at the same height.

[0013] Furthermore, there is a gap between the deck separation part and the deck main body part.

[0014] Furthermore, the edge of the hollow portion is a closed line.

[0015] Furthermore, the first base is distributed circumferentially along the edge of the hollow portion.

[0016] Further, the second base is distributed circumferentially along the edge of the deck separation portion.

[0017] Furthermore, the hollow portion is circular, elliptical, or polygonal.

[0018] Furthermore, the edge of the deck separation portion is circular, elliptical, or polygonal.

[0019] Furthermore, a connecting piece is provided between the bottom of the deck body and the supporting component.

[0020] Furthermore, the connecting members are distributed obliquely.

[0021] The beneficial effect of the present invention is that: by separating the deck used to support the equipment, the present invention can effectively prevent the equipment components with the excitation source from directly transmitting the excitation force to the equipment components without the excitation source, effectively block the equipment's own excitation load, and ensure the installation and use accuracy requirements of the equipment components without the excitation source. The present invention has a simple structure and does not increase additional costs in terms of manufacturing; at the same time, it can meet the emphasis requirements of equipment support. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 It is a top view of a preferred embodiment of the present invention.

[0023] Figure 2 for Figure 1 Middle AA section view. DETAILED DESCRIPTION

[0024] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, a separated ship vibration-damping deck comprises a deck main body 10 and a deck separation part 20 ; the deck main body 10 is provided with a hollow part 11 , and the deck separation part 20 is arranged in the hollow part 11 .

[0026] There is a gap between the deck separation part 20 and the deck main body part 10. The deck main body part 10 and the deck separation part 20 are located at the same height.

[0027] A first base 31 for supporting equipment components with an excitation source is fixedly disposed on the deck body 10. The first base 31 is distributed circumferentially along the edge of the hollow portion.

[0028] A second base 32 for supporting equipment components without an excitation source is fixedly disposed on the deck separation part 20. The second base 32 is distributed circumferentially along the edge of the deck separation part.

[0029] The edge of the hollow portion 11 is a closed line. The hollow portion is circular.

[0030] In other embodiments, the hollow portion may be elliptical or polygonal.

[0031] The edge of the deck separation portion 20 is rounded.

[0032] In other embodiments, the edge of the deck separation portion may be elliptical or polygonal.

[0033] A support component 21 is fixedly provided at the bottom of the deck separation part 20. A connecting member 12 is provided between the bottom of the deck main body 10 and the support component 21. The connecting member 12 is distributed obliquely.

[0034] The solution of the present invention can be used to install a device that has its own vibration source, and the device includes a device component with a vibration source and a device component without a vibration source. For example, a special measuring device includes a driving unit with a vibration source and a measuring unit without a vibration source. The vibration source in the driving unit will generate vibration. In order to ensure the precision of the measurement, the measuring unit should reduce or avoid vibration. The driving unit and the measuring unit are installed on a deck at the same height but separated, that is, the driving unit is fixed to the main part of the deck, and the measuring unit is fixed to the separated part. The driving unit and the measuring unit are directly separated, and the direct transmission of the excitation force is directly blocked, which can effectively reduce the influence of the excitation source on the adjacent equipment and effectively avoid the excitation load of the driving unit from being directly transmitted to the measuring unit.

[0035] The present invention can effectively prevent equipment components with vibration sources from directly transmitting vibration forces to equipment components without vibration sources by separating the deck used to support the equipment, thereby effectively blocking the equipment's own vibration load and ensuring the installation and use accuracy requirements of equipment components without vibration sources.

[0036] The invention has a simple structure and does not increase extra cost in manufacturing; at the same time, it can meet the requirements for equipment support.

[0037] The present invention can be widely applied to ships with the same requirements.

[0038] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
