Description

Technical Field

[0001] The present invention relates to the field of ship construction and design, and in particular to a steam system noise reduction device and a ship comprising the same. Background Art

[0002] During the operation of the steam system, the steam needs to be pressed into the steam equipment by continuously adjusting the control valve. Noise and vibration will be generated during the pressing process, and will be transmitted to the connected structure through the bracket, and then transmitted to the adjacent area through the structure. At present, the steam system of ordinary civilian ships is generally located in the engine room, far away from living places, and no special vibration and noise control is carried out. Since large ships (such as cruise ships) have large living areas and more functions, steam equipment near some living areas will also use steam systems, and vibration and noise control is required for these scenarios.

[0003] In the prior art, the steam system is often suspended from a bracket anchored on the upper deck by bolts. Therefore, the vibration of the steam valve and steam equipment is transmitted to the upper deck more directly. In addition, the bracket is difficult to construct and difficult to load. The low stiffness makes the natural frequency of the system low, and resonance is more common. Summary of the invention

[0050] Example 1

[0051] like Figure 1 As shown, this embodiment provides a steam system noise reduction device, which is used to reduce the noise of the steam valve 31 and the steam equipment 32 between the upper deck 1 and the lower deck 2. The steam valve 31 and the steam equipment 32 are connected by a steam pipe 33. The steam system noise reduction device includes a connecting member 41, a first support seat 42, a first elastic member 43, and a second support seat.

[0052] Both ends of the connecting member 41 are respectively connected to the upper deck 1 and the lower deck 2 , one end of the first support seat 42 is connected to the connecting member 41 , the first elastic member 43 is located on the upper surface of the first support seat 42 , and the steam valve 31 is located on the first elastic member 43 .

[0053] One end of the second support seat is connected to the middle of the steam pipe 33 , and the other end of the second support seat is connected to the upper surface of the lower deck 2 .

[0054] In this way, the steam valve 31 is connected to the upper deck 1 and the lower deck 2 through the first support seat 42 and the connecting piece 41.

The first elastic member 43 further provides a buffer for the steam valve 31 and the first support seat 42; the second support seat is connected to the steam valve 31 and the steam equipment 32 through the steam pipe 33, provides support for the steam pipe 33, and cooperates with the connecting piece 41 and the first support seat 42 to improve the structural stiffness, increase the natural frequency, and reduce the noise caused by resonance.

[0055] In this embodiment, the steam system noise reduction device further includes a reinforcing bracket 45, which is located on the lower surface of the lower deck 2 at a position corresponding to the second support seat. In this way, the lower deck 2 can be specifically reinforced to improve the safety of the structure; at the same time, the structural rigidity is improved, the natural frequency is increased, and the noise caused by resonance is reduced.

[0056] In this embodiment, the length of the reinforcing bracket 45 is equal to two supplementary material spacings. The specific size of the supplementary material spacings can be referred to in the prior art.
