Description

Technical Field

[0001] This utility model relates to the field of noise reduction device technology, and in particular to an environmentally friendly noise reduction device for construction project management. Background Technology

[0002] Construction noise reduction refers to taking a series of measures during construction to reduce noise pollution caused by construction activities to the surrounding environment. Application No.: CN202210007960.5 discloses an environmentally friendly noise reduction device for construction project management, including a fixed frame, a noise reduction plate one, a sliding groove, a noise reduction plate two, a noise reduction plate three, and a support leg mechanism. The front of the fixed frame is provided with a noise reduction plate one, and the interior of the fixed frame is provided with a sliding groove... This patent achieves noise reduction by interlacing two noise reduction plates inside the fixed frame. However, the noise reduction plates can only move in parallel and are arranged in a straight line for noise reduction, and the angle cannot be adjusted. In actual use, the straight-line noise reduction plates have limited sound reflection and cannot achieve a good noise reduction effect. Therefore, we introduce an environmentally friendly noise reduction device for construction project management. Utility Model Content

The upper and lower right ends of the first sound insulation board 1 are movably connected to second connectors 6. The right ends of the two second connectors 6 are movably connected to a third sound insulation board 7. The lower right end of the third sound insulation board 7 is threaded with a support device 8. The lower left and lower right ends of the first sound insulation board 1 are threaded with support devices 8. The lower left end of the second sound insulation board 2 is threaded with a support device 8. The upper end of the first sound insulation board 1 is fixedly connected to two support columns 5. The upper ends of the two support columns 5 are fixedly connected to a dustproof board 4.

[0025] In this embodiment, the support device 8 includes a cylinder 81, with a threaded rod 83 fixedly connected to the upper end of the cylinder 81. The diameter of the cylinder 81 is larger than the diameter of the threaded rod 83. Three equally spaced support legs 82 are fixedly connected to the lower part of the outer surface of the cylinder 81, and all three support legs 82 are inclined.

[0026] With the above solution, the support device 8 is installed together with the No. 3 sound insulation board 7 via the threaded rod 83, so that the support device 8 can be flexibly installed and disassembled.

[0027] In this embodiment, the right end of the second sound insulation board 2 and the left end of the third sound insulation board 7 are both arc-shaped structures, and the left and right ends of the first sound insulation board 1 are both arc-shaped structures.
