Description

Technical Field

[0001] This utility model relates to the field of noise reduction device technology, and in particular to a noise reduction device for fire protection engineering construction. Background Technology

[0002] Fire protection engineering construction involves the installation of water pipes and fire hydrants. During this process, holes need to be drilled in the ground or walls to allow for the use of fasteners to secure the water pipes to the walls and the fire hydrants to the ground. Drilling generates a significant amount of noise. To prevent noise pollution to the surrounding environment, soundproofing panels are often installed in the construction area to reduce the likelihood of noise spreading.

[0003] In practice, existing noise reduction devices for fire protection engineering construction typically involve installing sound insulation panels in the construction area and splicing multiple panels together to form a barrier structure. The sound insulation panels can absorb some noise and also intercept and block the transmission of noise, effectively reducing the probability of noise spreading outward.

[0004] However, in actual construction, drilling into walls or the ground generates a lot of dust. Although the enclosure structure composed of multiple soundproof panels can block the spread of noise, it is difficult to allow dust to escape from the inner area of ​​the enclosure structure. As a result, construction workers work in a dusty environment, which obviously has a negative impact on the construction environment. Therefore, this application proposes a noise reduction device for fire protection engineering construction that can reduce dust and thereby improve the construction environment. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background technology that dust is difficult to remove, resulting in a large amount of dust in the construction area.

The positioning plate is embedded in the positioning groove and engaged with it. Connecting plates are fixedly installed at both ends of the sound insulation panel that are far apart from each other, and a connecting groove is chiseled on the sound insulation panel and on one side of the connecting plate.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figures 1-5 As shown, this utility model proposes a noise reduction device for fire protection engineering construction, including a sound insulation board 1. Multiple sound insulation boards 1 can be installed according to actual needs. Two symmetrically arranged sound insulation boards 1 have a top plate 2 that is fitted together at their tops. The top plate 2 has a porous structure and good sound absorption effect. Glass wool boards 5 and two hollow sound-absorbing boards 4 are fixedly installed on the inner wall of the sound insulation board 1. The sound insulation board 1, glass wool boards 5, and hollow sound-absorbing boards 4 all have sound absorption functions, effectively absorbing and blocking noise, reducing the probability of noise diffusion. A dust removal channel 44 is carved inside the hollow sound-absorbing board 4. The dust exhaust channel 44 is connected to the drawer groove 41 carved at the bottom of the hollow sound-absorbing panel 4. A dust collection drawer 42 is fitted into the drawer groove 41, allowing dust falling from the dust exhaust channel 44 to be collected in the dust collection drawer 42 for easy dust collection. A dust collection box 3 is fixedly installed on the top of the hollow sound-absorbing panel 4. The dust collection box 3 is connected to the dust exhaust channel 44, and an exhaust fan 31 is fixedly installed on the dust collection box 3. The exhaust fan 31 can draw some of the dust from the construction area into the dust collection box 3, making it easier for the dust to enter the dust exhaust channel 44, effectively reducing the amount of dust in the construction area and improving the construction environment.

[0032] Furthermore, a positioning groove 12 is chiseled at the top of the sound insulation panel 1, and a positioning plate 21 is fixedly installed at the bottom of the top plate 2. When the top plate 2 is installed at the bottom of the sound insulation panel 1, the positioning plate 21 is embedded in the positioning groove 12 and tightly engaged with it, ensuring that the top plate 2 can be firmly installed on the top of the sound insulation panel 1. Connecting plates 13 are fixedly installed at both ends of the sound insulation panel 1 that are far apart from each other. A connecting groove 14 is chiseled at the end of the sound insulation panel 1 and on one side of the connecting plate 13. When multiple sound insulation panels 1 need to be spliced ​​together, the two sound insulation panels 1 can be firmly connected as one unit by the engagement and connection between the connecting plate 13 and the matching connecting groove 14, which effectively improves the robustness of the enclosure structure.

[0033] Secondly, the hollow sound-absorbing panel 4 has several hollow interlayers 43 inside. During the production process of the hollow sound-absorbing panel 4, sound-absorbing cotton 45 is filled into the hollow interlayers 43, which can improve the sound absorption effect of the hollow sound-absorbing panel 4.

[0034] Furthermore, several rollers 6 are rotatably installed on the bottom of the sound insulation panel 1. The rollers 6 can assist in the movement of the sound insulation panel 1, making it convenient to transport the sound insulation panel 1. Support wheels 7 are rotatably installed on the inner side wall of the sound insulation panel 1. The support wheels 7 can provide support points for the sound insulation panel 1, ensuring that the sound insulation panel 1 can stand stably on the ground and effectively prevent the enclosure structure composed of the sound insulation panels 1 from tipping over.

[0035] It is worth noting that two symmetrically arranged L-shaped limiting plates 11 are fixedly installed on the outer wall of the sound insulation panel 1. A baffle 8 is slidably installed between the two L-shaped limiting plates 11 to ensure that the baffle 8 can be adjusted in height. A foam board 81 is fixedly installed at the bottom of the baffle 8. When the sound insulation panel 1 moves to the designated position, the baffle 8 is pushed down and the lower surface of the foam board 81 is brought into close contact with the ground, thereby sealing the gap between the sound insulation panel 1 and the ground and enhancing the noise blocking effect of the sound insulation panel 1.

[0036] In this embodiment, during the installation of the noise reduction device, an equal number of sound insulation panels 1 are used according to the area of ​​the construction area. Multiple sound insulation panels 1 are spliced ​​together end to end to form a retaining wall structure through the interlocking connection between the connecting plate 13 and the connecting groove 14. After setting two retaining wall structures, a top plate 2 is added to the top of the sound insulation panels 1. Then, the retaining wall structure and the top plate 2 form an enclosure structure. If the construction work requires drilling holes in the wall, the enclosure structure is pushed and one end of its opening is attached to the wall. When the construction personnel enter the construction area, a sealing plate is added to the opening end of the enclosure structure away from the wall. If the construction work involves drilling holes in the ground, sealing plates are installed at both ends of the enclosure structure's openings to make the construction area a relatively closed environment.

[0037] Once construction begins, drilling will generate a significant amount of noise and dust. The sound insulation board 1, hollow sound-absorbing board 4, glass wool board 5, and porous roof panel 2 all possess excellent sound absorption properties, allowing the enclosure structure to absorb the noise generated in the construction area and prevent its outward diffusion, effectively improving noise reduction. When construction workers enter the construction area, they can plug the exhaust fan 31 into their portable battery to ensure it is operational. The airflow generated by the rotating fan blades blows towards the inside of the dust collection box 3 and then outwards from the dustproof net installed on the top cover 32 of the dust collection box 3. This process effectively reduces noise during construction. Some dust in the area is drawn into the dust collection box 3, and the dustproof net installed on the cover 32 can intercept the dust entering the dust collection box 3. The dust entering the dust collection box 3 falls into the dust collection drawer 42 along the dust discharge channel 44, which is convenient for dust collection. The dust collection drawer 42 can be opened to clean the dust. The noise reduction device in this application can not only absorb and block noise, reducing the probability of noise spreading outward and ensuring the noise reduction effect, but also collect most of the dust in the construction area, preventing a large amount of dust in the construction area from being inhaled into the respiratory tract by construction workers, avoiding physical discomfort to construction workers, and effectively improving the construction environment.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
