Description

Technical Field

[0001] The present application relates to the field of construction noise reduction, and in particular to a portable construction noise reduction device. Background Art

[0002] With the acceleration of urbanization, construction activities are becoming increasingly frequent, especially in densely populated urban areas. The impact of construction noise on the surrounding environment and residents' lives is becoming increasingly serious. Noise pollution not only disrupts residents' daily lives and affects their physical and mental health, but can also adversely affect wildlife and the ecological environment. Therefore, installing large soundproof enclosures around construction sites as sound barriers to block and absorb construction noise is a common noise reduction method. While existing noise reduction equipment can alleviate the construction noise problem to a certain extent, it still has some problems and limitations.

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The present application discloses a portable construction noise reduction device.

[0023] It should be noted that the sound insulator 7 is flexible and can be folded along with the folding of the bottom frame 2 and the top frame 5. An air filling port is provided on the sound insulator 7. When in use, air can be inflated into the sound insulator 7 to keep the cavity inside the sound insulator 7 filled and play a good role in sound insulation and noise reduction. Since a closed space is formed inside the cavity of the sound insulator 7, when sound waves enter the cavity, they will be repeatedly reflected on the wall surface of the cavity. Each reflection will consume a part of the energy of the sound wave, thereby reducing the intensity of the sound wave. At the same time, the air inside the cavity also has a damping effect on the propagation of the sound wave. When the sound wave propagates in the cavity, it will encounter air resistance, resulting in energy loss, thereby reducing the intensity of the sound wave. At the same time, the stability of the sound insulator 7 between the bottom frame 2 and the top frame 5 can be maintained. The sound collecting board 6 can be a glass fiber board or a mineral wool board, which can absorb sound and reduce reflection.

[0024] It should be further explained that the sound insulation body 7 can be used in combination according to actual construction requirements;

[0025] By adopting the above technical solution, when in use, the base 1 is arranged at the required construction site, the bottom frame 2 is fixed on the base 1, the top frame 5 is pulled upward until the connecting rod 1 3 and the connecting rod 2 4 are in a straight line, the first locking assembly and the second locking assembly are locked in sequence to keep the support of the bottom frame 2 and the top frame 5 stable, the sound insulation body 7 is expanded upward along with the top frame 5, and a proper amount of gas is injected into the cavity of the sound insulation body 7 to fill it, and then the sound collecting plate 6 is fixed on both sides of the sound insulation body 7 to achieve rapid deployment of the sound barrier.

Under the guidance of the pull groove 23, the pull rod 22 pushes the limit block 17 to slide downward until it passes through the limit opening 16 located below and engages with the through opening on the bottom frame 2, thereby limiting and fixing the hinge of the connecting rod 1 3 and the connecting rod 2 4.
