[0019] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0020] As attached Figure 1As shown, the utility model is a noise reduction structure for a boiler rapping device, wherein the rapping device 1 is arranged on a base 2, a noise reduction cover 3 is arranged on the base 2, the rapping device 1 is located inside the noise reduction cover 3, a plate 4 is arranged inside the noise reduction cover 3, a cavity 5 is formed between the noise reduction cover 3 and the plate 4, and a sound insulation layer 6 is arranged in the cavity 5. The above structure proposes an improved technical solution to the shortcomings in the prior art. When the structure is set, the rapping device 1 is arranged on the base 2, and the base 2 realizes the stable bearing of the rapping device 1, ensuring that the rapping device 2 can reliably and stably perform the rapping operation. In order to achieve the noise reduction function, the noise reduction cover 3 is arranged on the base 2, and the noise reduction cover 3 blocks the rapping device from the side and top, so that the rapping device 1 is located inside the noise reduction cover 3. For the specific structural setting of noise reduction, a plate 4 is arranged inside the noise reduction cover 3, a cavity 5 is formed between the noise reduction cover 3 and the plate 4, and a sound insulation layer 6 is arranged in the cavity 5. In this way, the rapping device 2 is isolated from the outside world, achieving sealing and sound insulation, and the rapping noise can be reduced from more than 100 decibels to less than 60 decibels, thereby achieving the purpose of noise reduction. The noise reduction structure of the boiler rapping device described in the utility model has a simple structure and can effectively achieve the function of sound insulation and noise reduction.

[0021] The rapping device 1 is positioned adjacent to a wall 7 on one side. The noise reduction housing 3 is not positioned adjacent to the wall 7. Instead, a cavity 5 is formed between the panel 4 positioned adjacent to the wall 7 and the wall 7. A sound insulation layer 6 is positioned within the cavity 5. In the aforementioned structure, the noise reduction housing, the sound insulation layer, and the panel form a sound insulation layer. If the rapping device 1 is positioned adjacent to the wall 7 on that side, the noise reduction housing 3 can be omitted. Instead, the wall can be used directly to replace the noise reduction housing 3, thereby maintaining noise reduction performance and saving costs.

[0022] The ends of two adjacent panels 4 are formed with inclined structures 8. When the two panels 4 are connected, the inclined structures 8 of the two adjacent panels 4 are affixed together and welded together. This structure ensures a secure connection between the adjacent panels. A door is provided on one side of the sound insulation layer to facilitate entry and exit. The door also includes a noise-reducing cover, sound insulation cotton layer, and panels, and also provides sound insulation.

When the top panel 9 and the side panel 10 are connected, the inclined surface structure 8 of the top panel 9 and the inclined surface structure 8 of the side panel 10 are affixed together and welded. The above structure provides a sound insulation layer for each exposed surface of the rapping device, thereby effectively shielding and soundproofing the rapping device.

[0024] The bottom of the side panel 10 is welded to the base 2. A reinforcing plate 11 is installed at the junction of the bottom of the side panel 10 and the base 2. The reinforcing plate 11 is welded to the junction of the top panel 9 and the side panel 10. Both the panel 4 and the reinforcing plate 11 are steel plates. This structure, with its welding and reinforcing plate installation, effectively improves the strength of the connection.

To achieve the noise reduction function, a noise reduction cover 3 is arranged on the base 2, and the noise reduction cover 3 blocks the rapping device from the side and top, so that the rapping device 1 is located inside the noise reduction cover 3. Regarding the specific structural setting of noise reduction, a plate 4 is arranged inside the noise reduction cover 3, a cavity 5 is formed between the noise reduction cover 3 and the plate 4, and a sound insulation cotton layer 6 is arranged in the cavity 5. In this way, the rapping device 2 is isolated from the outside world, achieving sealing and sound insulation, and the rapping noise can be reduced from more than 100 decibels to less than 60 decibels, thereby achieving the purpose of noise reduction.
