Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering construction, in particular to an engineering construction noise reduction enclosure. Background Art
[0002] Noise reduction fence is a facility used to reduce the impact of noise. It is usually used in municipal roads, construction sites and other places to reduce the impact of noise on the surrounding environment. This facility is usually made of metal or other materials and has the function of absorbing or blocking sound waves, thereby reducing the spread of noise. The working principle of noise reduction fence is mainly through the reflection, transmission and diffraction phenomena that occur when sound waves encounter fences during propagation. Through reasonable design and material selection, sound waves form a sound shadow area behind the fence, reducing the propagation range and intensity of noise. In the prior art, when some noise reduction fences with pores on the surface are used for a long time, dust is prone to adhere to their surfaces. When the attached dust accumulates more and blocks the pores, it will affect the absorption and reflection of sound, which will lead to a weakening of the noise reduction effect. Therefore, a noise reduction fence for engineering construction is proposed to address the above problems. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. A noise reduction enclosure for construction projects, which is provided with a cleaning brush, a driving gear, a track, a large gear, a fixed shaft, an active gear, an impeller, an exhaust pipe and a fixed box. When the device is used, the driving gear is driven by a double-axis motor to mesh with a rack, and the device can be controlled to move along the track around the outside of the noise reduction enclosure. Because the double-axis motor also drives the large gear to mesh with the small gear, the cleaning brush is driven to rotate through the fixed shaft at the top, so that the dust on the outside of the noise reduction enclosure can be cleaned in the process of controlling the movement of the device, because the rotating cleaning brush is also driven by the fixed shaft at the bottom The driving gear meshes with the driven gear, and the driven gear drives the impeller to rotate through the positioning shaft.
