Description

Technical Field

[0001] This invention relates to the field of industrial sound insulation equipment technology, specifically to an ultra-large steel structure sound insulation cover. Background Technology

[0002] A steel structure soundproof enclosure is a protective facility that significantly reduces noise transmission by enclosing the sound source and combining sound absorption and vibration isolation technologies. It is mainly used for noise reduction in industrial equipment. By constructing a soundproof chamber, the steel structure soundproof enclosure blocks the transmission of noise, which can protect the hearing of workers and control noise pollution from equipment. The design needs to be similar to the outline of the sound source equipment to reduce the volume of the soundproof enclosure and the noise radiation area. It is assembled in conjunction with steel structure equipment.

[0003] In the prior art, patent document CN215563825U discloses a soundproof steel structure wall, including light steel keel, supporting steel pipe, mounting plate, baffle, sound insulation block, mounting bolt, decorative panel, perforated sound-absorbing cotton, concave-convex plate, sound-absorbing groove, protective plate, and dust cover. Multiple light steel keels are fixed in parallel by supporting steel pipe to form a crisscross steel mesh. The top and bottom of multiple light steel keels are vertically fixed by mounting plates. Multiple sets of baffles are welded to the front and back of the light steel keel. Multiple sound insulation blocks are fixed between the front and back baffles by mounting bolts. A decorative panel is fixed to the rear end face of the light steel keel. Perforated sound-absorbing cotton is fixed to the front end face of the light steel keel. A concave-convex plate is adhered to the front end face of the perforated sound-absorbing cotton. Multiple irregular sound-absorbing grooves are opened on the front of the concave-convex plate.

[0004] However, the above-mentioned technical solutions have insufficient structural stability. The oversized design results in weak overall rigidity, making them susceptible to deformation and shaking due to equipment vibration and external loads. Long-term use can lead to loose connections, affecting sound insulation and sealing. Furthermore, most of them are single-seal structures, which can easily cause noise leakage at frame joints and installation gaps. They also cannot adapt to the slight displacement caused by equipment vibration, resulting in obvious sound insulation blind spots, poor adaptability, low modularity of components, cumbersome on-site installation and debugging, requiring a lot of manpower and resources, and are difficult to adapt to oversized and different types of oversized noise sources, thus lacking versatility.

[0005] Based on this, the present invention provides an ultra-large steel structure soundproof enclosure to solve the problems mentioned in the background art. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing an ultra-large steel structure soundproof enclosure to solve the problems of poor structural stability, uneven sound insulation effect, complex installation and debugging, and insufficient adaptability.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an extra-large steel structure soundproof cover, including an external frame structure, the external frame structure including side covers, the top ends of the two side covers are equipped with top caps, and the top covers are fixedly connected to each other.

[0008] The external frame structure also includes a supporting foundation, with steel structure support columns fixedly connected to the top of the multiple supporting foundations. The multiple steel structure support columns are located on one side of the side cover, and an internal cover is fixedly connected to the other side of the multiple steel structure support columns.

[0009] A side mounting structure is provided between the steel structure support columns.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the two side enclosures are symmetrically arranged, serving as lateral sealing structures for the soundproof enclosure, blocking the lateral propagation of noise, and providing installation support for the top structure; the top cover is installed on the top of the two side enclosures, serving as a top seal and transition connection, preventing sound leakage from the top gap; the top enclosure is fixedly connected between the two top covers, forming a complete top sealing structure, and its arc-shaped design can adapt to different site space requirements, while enhancing the rigidity of the top structure. Combined with sound insulation panels, it achieves top noise blocking, and the inner enclosure is fixed to one side of the steel structure support column. Together with the outer side enclosure, it forms a double-layer sound insulation structure. Its core function is to further enhance the sound insulation effect, buffering noise transmission through the double-layer gap and improving noise reduction efficiency. The supporting foundation uses reinforced concrete to provide a stable load-bearing foundation for the steel structure support columns, distributing the overall weight and equipment vibration load, and preventing the sound insulation enclosure from settling and deforming due to uneven stress. The steel structure support columns are fixed to the top of the supporting foundation and located on one side of the side enclosure. As the core load-bearing component, they transfer the load to the supporting foundation and provide a precise installation platform for the side installation structure and steel structure beams, ensuring that the overall structure is subjected to balanced stress.

[0011] The beneficial effects of this invention are:

[0012] 1) This invention forms a complete seal through the sealing plate and the top cover, and the middle gap can buffer the transmission of noise, which greatly improves the noise reduction efficiency; the connecting terminals and spring connecting terminals of the side mounting structure ensure that the sound insulation board is tightly attached to the frame, fills all the joint gaps, completely solves the problem of sound leakage in the gaps of traditional sound insulation covers, achieves all-round uniform sound insulation, and the noise reduction effect is better than that of a single sealing structure.

[0013] 2) The present invention uses spring connecting terminals that are fixed at equal intervals to one side of the outer wall of the fixed sleeve, located on one side of the connecting sleeve, to provide a flexible buffering effect, adapt to the small displacement caused by equipment vibration, and avoid the rigid connection from loosening or being damaged due to vibration. The rotating plate is fixed to the end of the spring connecting terminal away from the fixed sleeve and is hinged to the connecting shaft. The connecting shaft is fixed to the outer wall of the fixed sleeve and located on one side of the spring connecting terminal, allowing the rotating plate to make slight adjustments around the connecting shaft. Rotating frame one is fixed to the top of the rotating plate and is rotatably connected to rotating frame two to realize multi-angle adjustment, adapt to the installation angle and vibration displacement of the steel structure support column, and ensure that the connection part is always tightly fitted.

[0014] 3) This invention connects the steel structure support columns to the support foundation, and the steel structure beams connect each set of support columns in series. The middle span connecting beam strengthens the middle area, resulting in a balanced overall force. This can effectively resist the load pressure and equipment vibration caused by the ultra-large size, and avoid structural deformation and loosening. At the same time, the side installation structure eliminates vibration stress through multi-node linkage, ensuring long-term stability and adapting to the high-frequency vibration requirements of industrial scenarios.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, each of the steel structure support columns is arranged in pairs, and a steel structure beam is fixedly connected to the top of each of the steel structure support columns. A plurality of top purlins are fixedly connected to the top of each of the steel structure beams.
