Description

Technical Field

[0001] This invention relates to the field of construction machinery, specifically to a noise-blocking fence for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called a "construction site" or "building site."

[0003] During construction, noise and dust are generated, causing varying degrees of pollution to the surrounding environment. Existing fences only serve as barriers and are extremely ineffective at blocking noise, leading to complaints from nearby residents and affecting the construction progress. They also do not effectively block dust, resulting in severe dust pollution. Water spraying for dust suppression is ineffective due to its small coverage area. Summary of the Invention

[0034] The working principle of this invention is:

[0035] This invention relates to a noise-blocking fence for building construction. In use, it can adopt a modular structure, assembling the outer shell 1 and the middle pole 10 to form a construction site enclosure. To meet sound insulation requirements, the device has a raised top plate 4 and a ground strip 7 to seal the bottom gaps, increasing the overall blocking area and eliminating gaps. It also has a built-in sound-absorbing plate with sound-absorbing bowls 18 tightly arranged, so that sound waves passing through the inclined perforated plate 19 are reflected and canceled between the sound-absorbing bowls 18, thus canceling out noise and greatly improving the sound-absorbing capacity. It also has a vacuum shell 21, and uses a wind-driven pneumatic circulation component with a one-way air outlet component to suck out the air inside the vacuum shell 21, making the air inside the vacuum shell 21 rarefied, minimizing the medium for sound wave propagation, achieving a hollow sound insulation effect, and ensuring sound insulation performance.

[0036] Furthermore, the exhaust device inside the pneumatic circulation component is driven by the motor 5 to rotate the rotating rod 13, which in turn drives the impeller 26 to rotate at high speed. To ensure the rotation speed, the combination of the rotating wheel 13 and the transmission component 44 can significantly increase the rotation speed, so that the air inside the vacuum shell 21 is continuously pushed to the lower space of the inner shell 12 and discharged through the one-way air outlet component. The one-way air outlet component has an anti-reverse structure to prevent external air and debris from entering the inner shell 12 and ensure the stable operation of the device.

[0037] Simultaneously, while providing sound insulation, it also has the ability to spray water. When spraying water, the water flowing through the water supply pipe 30 pushes the toggle frame, which in turn pushes the lever 33 to deflect through the impeller 32 on the toggle frame. Then, through the action of the ball 36 and the ring 37, the nozzle 28 can swing, which sprays water into the lower space, forming a large-area fan-shaped water curtain. It also cleans the outer wall of the inclined perforated plate 19, ensuring sound absorption. Furthermore, after dust comes into contact with the outer shell 1 and the top plate 4, it will be guided upward by the top plate 4 to the water spray position, ensuring that the dust settles completely.

[0038] This invention features a rationally designed structure that, when used for construction site enclosure, significantly enhances sound absorption capabilities, minimizes the medium through which sound waves propagate, and achieves a hollow sound insulation effect. The device incorporates a highly efficient vacuum structure, enabling efficient vacuuming and continuous internal pressure maintenance to ensure sound insulation performance. Furthermore, the device features a flexible water spray structure that forms a large-area fan-shaped water curtain, ensuring the cleanliness of the sound-collecting structure surface and guaranteeing the full settling of dust.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
