Description

Technical Field

[0001] The utility model belongs to the technical field of highway construction engineering, and particularly relates to a noise insulation device for municipal highway construction engineering. Background Art

[0002] Patent publication number CN221345334U discloses a noise isolation device for municipal highway construction projects. The device relates to the technical field of noise isolation devices and includes a sliding platform with a sliding frame slidably connected to the top of the platform. A sound insulation board is fixedly connected to the inner side of the sliding frame. A connecting groove is formed at the right end of the sliding frame, and a connecting block is fixedly connected to the left end of the sliding frame. A fixing mechanism is provided on the side of the sliding frame. The utility model utilizes aluminum honeycomb perforated sound-absorbing panels. The honeycomb core inside the panels is divided into numerous enclosed cells, which block air flow and impede sound waves, thereby improving the sound absorption coefficient. Furthermore, the uniquely shaped wave-shaped sound-absorbing sponge is used for sound insulation and noise reduction. It has strong high-frequency absorption capacity and excellent flame retardancy. Furthermore, the damping sound insulation board provides sound isolation, thereby effectively reducing noise pollution generated by municipal highway construction projects. However, the aforementioned noise isolation device cannot be adaptively adjusted to different construction noise levels during use, which reduces the noise isolation effect and flexibility. Therefore, a noise isolation device for municipal highway construction projects is proposed. Utility Model Content

[0018] In general, terms can be understood, at least in part, from their use in context. For example, depending at least in part on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending at least in part on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0019] It will be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” means not only “directly on” something but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” means not only “on” or “above” something but also includes the meaning of being “on” or “above” something with no intervening features or layers.

A limiting mechanism is provided above the noise insulation board 1 for further fixing the position of the baffle 6 after adjustment, and increasing or decreasing the number of sound-absorbing strips 4 according to different construction noise levels. At the same time, the noise insulation board 1 and the sound-absorbing strip 4 are both made of sound insulation material.

[0023] The limit mechanism includes a limit plate 7 fixed to the top side wall of the noise insulation board 1, and the upper surface of the limit plate 7 is provided with a symmetrically distributed limit channel 12 in the vertical direction.

Then the pull plate 9 is released, and under the elastic force of the reset spring 10, the limit rod 8 is engaged with the corresponding position limit groove 11 to fix the position of the slide plate 5, thereby fixing the position of the baffle 6. Then, a corresponding number of sound-absorbing strips 4 are placed inside the adjustment groove 2 to effectively absorb and isolate the noise of the construction site.
