The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1:

[0023] Please see Figure 1 As shown, this utility model provides an environmentally friendly construction site noise control device, including a base 1, a support sleeve 2 installed on the top of the base 1, a support column 3 telescopically installed inside the support sleeve 2, a first adjustment knob 4 locked on the outside of the support sleeve 2, a rotating shaft 7 fixedly installed at the upper end of the support column 3, a snap-fit ​​plate 6 rotatably installed at both ends of the rotating shaft 7, a fixed seat 5 snap-fitted at the front end of the snap-fit ​​plate 6, a second adjustment knob 8 locked on the left end of the rotating shaft 7 and located outside the snap-fit ​​plate 6, a positioning bracket 9 installed on the front of the fixed seat 5, a base plate 10 pulled out on both sides of the inner cavity of the positioning bracket 9, and a sound insulation plate 13 fixedly installed on the front of the base plate 10.

[0024] This technical solution allows for the adjustment of the height of the sound insulation board 13 according to the height of the noise source at the construction site through the telescopic cooperation of the support sleeve 2 and the support column 3, as well as the first adjustment knob 4. The setting of the rotating shaft 7, the snap-fit ​​plate 6, and the second adjustment knob 8 can adjust the angle of the sound insulation board 13, so that the sound insulation board 13 is better oriented towards the noise source, thereby improving the noise reduction effect. At the same time, the base plate 10 can be pulled out in the positioning bracket 9, which makes it easy to adjust the unfolded width of the sound insulation board 13 according to actual needs, so as to adapt to different noise areas.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the sound insulation panel 13 is composed of an outer protective panel 14, a middle sound-absorbing layer 15, and an inner reflective layer 16. The middle sound-absorbing layer 15 is installed on the inner surface of the outer protective panel 14, and the inner reflective layer 16 is installed on the inner surface of the middle sound-absorbing layer 15. Side baffles 11 are fixedly installed at both ends of the substrate 10. Rubber pads 12 are adhered to the inner side of the side baffles 11, and the inner surface of the rubber pads 12 is connected to the end of the sound insulation panel 13.

[0027] Adopting such Figure 1 The technical solution shown is that the middle sound-absorbing layer 15 of the sound insulation board 13 is made of recycled fiber cotton material. Recycled fiber cotton is made by recycling and processing waste fibers, which reduces the consumption of new raw materials, reduces resource waste and environmental pollution in the production process. Moreover, after the device is abandoned, the recycled fiber cotton material is easy to degrade and will not cause long-term pollution to the environment. The side baffle 11 and rubber pad 12 can fix and protect the sound insulation board 13, preventing the sound insulation board 13 from shaking or shifting during use. The locking knob 17 can firmly fix the base plate 10 in the positioning bracket 9, further ensuring the stability of the entire device structure.

[0028] Secondly, in the technical solution, locking knobs 17 are installed through and locked on both sides of the back of the positioning card holder 9, and the locking end of the locking knob 17 is firmly connected to the surface of the substrate 10; the middle sound-absorbing layer 15 is made of recycled fiber cotton material; the support sleeve 2 has an expansion groove inside, and the lower end of the support column 3 is located inside the expansion groove and is firmly connected to the locking end of the first adjustment knob 4.

[0029] Its adoption is as follows Figure 1 The technical solution shown uses the support sleeve 2 in conjunction with the support column 3, rotating shaft 7 and other components to achieve flexible adjustment of height, angle and width, adapting to various construction scenarios; the material selected is recycled fiber cotton as the sound-absorbing layer, which has both good noise reduction performance and environmental protection attributes, practicing the green concept; while the design of components such as side baffle 11, rubber pad 12, locking knob 17 enhances the stability and durability of the device, effectively ensuring the noise reduction function and service life of the device.

[0030] Example 3:

[0031] This utility model is as follows Figures 1-4 As shown, the fixing base 5 has a snap-fit ​​groove inside, and the front end of the snap-fit ​​plate 6 snaps into the inside of the snap-fit ​​groove and is fastened; the base plate 10 is symmetrically slidably arranged inside the positioning bracket 9, and the front of the base plate 10 has an installation groove that connects to the back of the sound insulation plate 13.

[0032] The above technical solution, with the snap-fit ​​design of the internal snap-fit ​​groove of the fixing base 5 and the snap-fit ​​plate 6, ensures a stable connection between the rotating shaft 7, the snap-fit ​​plate 6 and the fixing base 5. This ensures the integrity of the structure when adjusting the angle of the sound insulation plate 13, prevents parts from falling off, and ensures stable operation of the device. The structure of the base plate 10, which slides symmetrically in the positioning bracket 9 and has an installation groove on the front, not only facilitates flexible adjustment of the unfolded width of the sound insulation plate 13 according to the noise area, but also enables the sound insulation plate 13 to be installed and disassembled quickly and accurately, facilitating maintenance and replacement.

[0033] The working principle of this utility model is as follows: When facing noise sources of different heights, by loosening the first adjustment knob 4, the support column 3 can move up and down within the telescopic groove of the support sleeve 2. After adjusting to the appropriate height, the knob is tightened to fix it, achieving precise vertical adjustment. The rotating shaft 7, in conjunction with the second adjustment knob 8, can drive the snap-fit ​​plate 6 and the fixing seat 5 to rotate, allowing the sound insulation plate 13 to flexibly adjust its angle and face the direction of noise propagation. The base plate 10 in the positioning bracket 9 can be symmetrically pulled out and fixed with the locking knob 17, adjusting the unfolding width of the sound insulation plate 13 as needed to cover different noise areas. In terms of acoustic noise reduction, after noise propagates to the sound insulation plate 13, the outer protective plate 14 resists external physical impact and protects the internal structure. The middle sound-absorbing layer 15 uses the pores between the fibers to reflect and absorb sound waves multiple times, converting sound energy into heat energy. The inner reflective layer 16 reflects the unabsorbed noise back to the sound-absorbing layer. Through repeated action, the noise intensity is greatly reduced, thereby achieving efficient noise reduction at the construction site.
