Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship technology, in particular to a split ship vibration reduction deck. BACKGROUND

[0002] Ship vibration has always been a problem that needs to be paid attention to in ship design, which can be mainly divided into two categories: total vibration and local vibration. Excessive ship vibration can cause local structure fatigue damage, machine equipment failure and affect the health of the crew. The deck of the ship is a platform for equipment installation and crew operation and residence, and effective control of the deck vibration is an important measure to ensure the habitability, safety and functionality of the ship.

[0003] The special measuring equipment on the deck of the special operation ship has high requirements for the vibration control of the installation deck, and the equipment driving unit itself is a vibration source, so the 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 ship 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 rigidity of the deck structure below the equipment to reduce the vibration.

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

[0006] 1. Some equipment does 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 equipment that includes a driving unit (vibration source) and the measuring unit has high requirements for the deck vibration, the positions of the two are very close, and simply increasing the rigidity of the deck has poor effect. SUMMARY

[0009] The technical problem to be solved by the present application is to overcome the above-mentioned defects existing in the prior art, and to provide a split ship vibration reduction deck.

[0010] The present application solves the above-mentioned technical problems by the following technical solutions:

[0011] A split ship vibration reduction deck, comprising a deck main body part, further comprising a deck separation part; the deck main body part is provided with a hollow part, and the deck separation part is arranged in the hollow part; the bottom of the deck separation part is fixedly provided with a support part; the deck main body part is fixedly provided with a first base for supporting an equipment part with a vibration source; and the deck separation part is fixedly provided with a second base for supporting an equipment part without a vibration source.

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

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

[0014] Furthermore, the edges of the openwork section are closed lines.

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

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

[0017] Furthermore, the cutout portion can be circular, elliptical, or polygonal.

[0018] Furthermore, the edges of the deck separation section are circular, elliptical, or polygonal.

[0019] Furthermore, a connector is provided between the bottom of the main deck section and the supporting components.

[0020] Furthermore, the connectors are distributed obliquely.

[0021] The beneficial effects of this invention are as follows: By separating the deck used to support the equipment, this invention effectively prevents equipment components with vibration sources from directly transmitting vibration force to equipment components without vibration sources, effectively blocking the equipment's own vibration load and ensuring the installation and usage accuracy requirements of equipment components without vibration sources. This invention has a simple structure, does not increase manufacturing costs, and simultaneously meets the requirements for equipment support. Attached Figure Description

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

[0023] Figure 2 for Figure 1 Sectional view of AA. Detailed Implementation

[0024] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, a detachable ship vibration damping deck includes a main deck section 10 and a detachable deck section 20; the main deck section 10 has a perforated section 11, and the detachable deck section 20 is located inside the perforated section 11.

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

[0027] The deck main body part 10 is fixed with a first base 31 for supporting the equipment component with the vibration source. The first base 31 is distributed along the edge of the hollow part in a circumferential direction.

[0028] The deck separation part 20 is fixed with a second base 32 for supporting the equipment component without the vibration source. The second base 32 is distributed along the edge of the deck separation part in a circumferential direction.

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

[0030] In other embodiments, the hollow part can be elliptical, or polygonal.

[0031] The edge of the deck separation part 20 is circular.

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

[0033] The bottom of the deck separation part 20 is fixed with a support component 21. The bottom of the deck main body part 10 and the support component 21 are provided with a connecting piece 12. The connecting piece 12 is distributed in an oblique direction.

[0034] The scheme of the present application can be used for installing the equipment with the vibration source itself, which includes the equipment component with the vibration source and the equipment component without the vibration source. For example, a special measuring equipment includes a driving unit with the vibration source and a measuring unit without the vibration source. The vibration source in the driving unit can generate vibration. In order to ensure the precision of the measurement, the vibration condition should be reduced or avoided. The driving unit and the measuring unit are installed on the same height but on the separated deck, i.e. the driving unit is fixed on the deck main body part and the measuring unit is fixed on the separation part. The driving unit and the measuring unit are directly separated, which directly blocks the direct transmission of the vibration force, can effectively reduce the influence of the vibration source on the adjacent equipment, and can effectively avoid the direct transmission of the vibration load of the driving unit to the measuring unit.

[0035] The present application can effectively avoid the direct transmission of the vibration force from the equipment component with the vibration source to the equipment component without the vibration source by separating the deck for supporting the equipment, effectively blocks the vibration load of the equipment itself, and ensures the installation and use precision requirements of the equipment component without the vibration source.

[0036] The present application has simple structure, does not increase additional cost in manufacturing, and can meet the emphasized requirements of the equipment support.

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

[0038] Although the specific embodiments of the present application have been described above, it is understood by those skilled in the art that the present application is only illustrated by way of example, and the scope of protection of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to the embodiments without departing from the principles and essence of the present application, and such changes and modifications fall within the scope of protection of the present application.
