Description

Technical Field

[0001] This application relates to the field of cabin noise reduction technology, and specifically discloses a novel cabin noise reduction component. Background Technology

[0002] The engine room is the internal space of a ship's new energy ship, pneumatic ship, or fuel oil ship, used to install and operate various mechanical equipment. It is generally used to house mechanical equipment including main engines, auxiliary engines, generators, water pumps, air conditioners, etc.

[0003] However, the mechanical equipment inside ships often vibrates and generates a lot of noise during operation. This noise not only seriously affects the working comfort of the crew and reduces their work efficiency, but also causes some equipment to malfunction due to noise interference. For example, it affects the normal operation of sonar equipment and interferes with the detection of underwater targets (reefs, shipwrecks, submarines, etc.). Therefore, in view of this, the inventors have provided a new type of engine room noise reduction component to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that mechanical equipment in the engine room of traditional ships generates a lot of noise during operation, which not only affects the working comfort of the crew, but also interferes with the operation and use of the equipment.

[0005] To achieve the above objectives, the basic solution of this utility model provides a novel cabin noise reduction component, including a noise reduction box for placing mechanical equipment. The bottom of the noise reduction box is provided with a shock-absorbing support layer for placing and supporting the mechanical equipment. A soundproof door is provided on one side of the noise reduction box. A honeycomb ventilation plate is installed on the top of the noise reduction box to facilitate air circulation inside the noise reduction box. A wiring connection pipe is also connected to one side of the noise reduction box to facilitate the installation and wiring of the mechanical equipment with the outside. Noise reduction side plates are provided on the inner side walls of the noise reduction box. A door handle is detachably installed on the outer side of the soundproof door.

[0006] The principle and effect of this basic scheme are as follows:

[0007] 1. Compared with existing technologies, this utility model accommodates and places mechanical equipment in the ship's engine room by setting up a noise reduction box and soundproof door. By setting up honeycomb ventilation panels and noise reduction side panels in the noise reduction box, it is easy to isolate and reduce noise for each piece of equipment. By setting up a shock-absorbing support layer, it is easy to support the mechanical equipment placed in the noise reduction box and simultaneously perform shock absorption treatment on the mechanical equipment, thereby reducing the vibration noise generated by the mechanical equipment. By setting up through-line connecting pipes, it is easy to connect the mechanical equipment with other external equipment. The noise generated by the mechanical equipment is blocked and weakened within the noise reduction box, which greatly prevents the transmission of noise to the outside of the ship's engine room. This provides a comfortable working environment for the crew and avoids the adverse effects of messy noise on the operation of other equipment. It solves the problem that the mechanical equipment in the traditional ship's engine room generates a lot of noise during operation, which not only affects the working comfort of the crew but also interferes with the operation and use of the equipment.

[0008] Furthermore, a viewing window is provided in the middle of the soundproof door. By providing a viewing window in the soundproof door, it is convenient to observe the actual operation of the mechanical equipment inside the noise reduction box, thereby ensuring the safe operation of the mechanical equipment.

[0009] Furthermore, the vibration damping support layer includes a sound-absorbing pad disposed on the inner bottom surface of the noise reduction box and a support pad disposed on the sound-absorbing pad for supporting the mechanical equipment. By setting up the support pad, the mechanical equipment is supported, and by setting up the sound-absorbing pad, the noise inside the noise reduction box is weakened and reduced, thereby preventing the noise generated by the operation of the mechanical equipment inside the noise reduction box from escaping to the ship outside the engine room.

[0010] Furthermore, sound-absorbing cotton strips are installed around the perimeter of the soundproof door. By installing sound-absorbing cotton strips around the perimeter of the soundproof door, it is convenient to perform sound insulation treatment on the installation gap between the soundproof door and the noise reduction box, thereby reducing the transmission of noise outward from the installation gap.

[0011] Furthermore, the inner sides of both the noise-reducing side panel and the through-line connecting pipe are equipped with sound-absorbing cotton layers. By installing sound-absorbing cotton layers on the inner sides of the noise-reducing side panel and the through-line connecting pipe, the noise generated inside the noise-reducing box is further weakened, resulting in a better noise reduction effect.

[0014] Figure 2 It shows Figure 1 Enlarged view of the structure of section A in the middle. Detailed Implementation

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

Through-line connecting pipe; 6. Noise reduction side panel; 7. Door handle; 8. Viewing window; 9. Sound-absorbing pad; 10. Support pad; 11. Door side sound-absorbing cotton strip; 12. Sound-absorbing cotton layer.

[0017] A novel cabin noise reduction component, implementing, for example Figure 1 As shown: It includes a noise reduction box 1 for placing mechanical equipment 2. The bottom of the noise reduction box 1 is provided with a shock-absorbing support layer for placing and supporting the mechanical equipment 2. A soundproof door 3 is provided on one side of the noise reduction box 1. A honeycomb ventilation plate 4 is installed on the top of the noise reduction box 1 to facilitate the air circulation inside the noise reduction box 1. A wiring connection pipe 5 is also connected to one side of the noise reduction box 1 to facilitate the installation and wiring of the mechanical equipment 2 with the outside. Noise reduction side plates 6 are provided on the inner side walls of the noise reduction box 1. A door handle 7 is detachably installed on the outside of the soundproof door 3.

[0018] The soundproof door 3 has a viewing window 8 in the middle, which may be made of glass or acrylic sheet material. Figure 2 As shown, the vibration damping support layer includes a sound-absorbing pad 9 on the inner bottom surface of the noise reduction box 1 and a support pad 10 on the sound-absorbing pad 9 for supporting the mechanical equipment 2. Soundproof door 3 has sound-absorbing cotton strips 11 installed on its periphery. The inner sides of the noise-reducing side panel 6 and the connecting pipe 5 are provided with sound-absorbing cotton layers 12. The noise-reducing side panel 6 may include, but is not limited to, being made of a honeycomb panel.

[0019] In the specific implementation of this utility model, the mechanical equipment 2 in the ship's engine room is placed in separate noise reduction boxes 1. During the operation of the mechanical equipment 2, the soundproof door 3 must be kept closed. The sound-absorbing cotton strips 11 on the side of the door seal the installation gap between the soundproof door 3 and the noise reduction box 1. The sound-absorbing cotton layer 12 and the honeycomb ventilation plate 4 weaken the noise inside the noise reduction box 1. When the mechanical equipment 2 vibrates during operation, the vibration is transmitted to the sound-absorbing pad 9 through the support pad 10, and the sound-absorbing pad 9 weakens the vibration, thereby achieving the purpose of noise reduction.

[0020] Compared with existing technologies, this utility model accommodates and places the mechanical equipment 2 in the ship's engine room by setting up a noise reduction box 1 and a soundproof door 3. By setting up a honeycomb ventilation plate 4 and a noise reduction side plate 6 in the noise reduction box 1, it is easy to isolate and reduce noise for each piece of equipment. By setting up a shock-absorbing support layer, it is easy to support the mechanical equipment 2 placed in the noise reduction box 1 and simultaneously perform shock absorption treatment on the mechanical equipment 2, thereby reducing the vibration noise generated by the mechanical equipment 2. By setting up a through-line connecting pipe 5, it is easy to connect the mechanical equipment 2 with other external equipment. The noise generated by the mechanical equipment 2 is blocked and weakened within the noise reduction box 1, which greatly prevents the transmission of noise to the outside of the ship's engine room. This provides a comfortable working environment for the crew and avoids the adverse effects of messy noise on the operation of other equipment. It solves the problem that the mechanical equipment 2 in the traditional ship's engine room generates a lot of noise during operation, which not only affects the working comfort of the crew, but also interferes with the operation and use of the equipment.
