Description

Technical Field

[0001] This utility model relates to the field of sound insulation technology, and in particular to a modular sound-absorbing and sound-insulating cover. Background Technology

[0002] Besides outdoor fixed facilities such as fans, cooling towers, and exhaust systems, noise is also generated by indoor machinery in factories. This noise can penetrate factory walls and cause noise pollution to surrounding residents. Currently, to reduce the impact of noise pollution, sound insulation cotton or panels are usually installed on the walls to block noise. However, the noise reduction effect of using sound insulation cotton or panels is generally limited, and they also present the problem of inconvenient installation. Utility Model Content

[0003] This utility model provides a modular sound-absorbing and insulating cover to overcome the shortcomings of the prior art and solve the problems of poor noise reduction effect and inconvenient installation of existing noise reduction facilities, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A modular sound-absorbing and insulating cover includes a rectangular housing. Multiple slots are formed on two adjacent outer side walls of the housing. A rectangular groove is formed on one side of the housing. A cover plate is fixed to the housing with adhesive. Multiple clips are formed on the lower wall of the cover plate. The housing, consisting of the housing and cover plate, protects the internal sound-insulating components and also blocks noise to a certain extent. Both the housing and cover plate can be made of galvanized iron sheet to enhance protective strength. The clips and slots facilitate assembly and connection between adjacent sound-insulating panels. The clips and slots can be configured as V-shaped tongue-and-groove joints on the four side walls of the housing. While simpler than clips and slots, this structure has lower stability after assembly and is therefore considered an alternative. When two adjacent modular sound-absorbing and insulating covers are connected, the clips on the cover plate engage with the slots on one of the adjacent side walls and are secured with screws.

[0006] Multiple sound insulation components are placed inside the rectangular groove. The sound insulation components are long and strip-shaped, and the inside of the sound insulation components is hollow, creating a vacuum state. The sound insulation components are made of plastic, and the use of vacuuming to reduce the noise transmission medium significantly improves the noise insulation effect.

[0007] Furthermore, multiple limiting protrusions are provided on both sides of the sound insulation component. The limiting protrusions are fixed to the bottom of the rectangular groove, and each sound insulation component is limited by the limiting protrusions.

[0008] Furthermore, buffer rectangular frames are attached to the top and bottom sides of the sound insulation component. The buffer rectangular frames are made of flexible material, which can improve the fixing effect of the sound insulation component and prevent it from moving.

[0009] Furthermore, the sound insulation component has multiple inclined plates inside, which enhances its strength and prevents deformation during vacuuming.

[0010] Furthermore, one end of the sound insulation component is sealed, while the other end is open. An embedded post is fixed to the open end of the sound insulation component with adhesive. A raised edge is provided on the outer side of the embedded post. The sealed embedded post facilitates the connection and operation of the air nozzle.

[0011] Furthermore, the outer periphery of the embedded column is provided with multiple embedded grooves, and the inner wall of the open end of the sound insulation component is provided with multiple embedded blocks. The embedded blocks are embedded in the embedded grooves to improve the fixing effect when the embedded column and the sound insulation component are sealed together, mainly through the contact area between the two.

[0012] Furthermore, to facilitate vacuuming operations and ensure a good seal after vacuuming, an inner tube is inserted into the embedded column. The inner end of the inner tube has an inner end ring located inside the embedded column. A first hole is formed at the inner end of the inner tube, and a tapered hole connects to the outer end of the first hole. The outer end of the tapered hole is the larger end, and a second hole connects to the outer end of the tapered hole. A third hole connects to the outer end of the second hole, and the inner diameter of the third hole is larger than that of the second hole. The outer end of the inner tube passes through… The threaded connection has a tightening ring, the inner end of which is tightened against the outer end of the embedded post. The outer end of the inner tube is connected to an end cap via a thread, and the inner post is connected to the inner end of the inner tube via a thread. A movable rod is mounted on the inner post, and an inner top plate is mounted on the outer end of the movable rod. The inner wall of the end cap is tightly attached to the outer end face of the inner top plate. A conical head is mounted on the inner end of the movable rod, and the outer circumference of the inner end of the conical head is tightly attached to the inner wall of the conical hole. A sealing post is mounted on the inner end of the conical head, and the sealing post is inserted into the first hole.

[0013] The advantages of the above technical solution are:

[0014] This invention blocks noise by reducing the medium through which sound propagation occurs, thereby improving the sound insulation effect. It also facilitates the connection and fixing of two adjacent sound insulation panels, as well as the effect after fixing. Attached Figure Description

[0023] like Figures 1-7 As shown, a modular sound-absorbing and sound-insulating cover includes a rectangular shell 1. Multiple slots 13 are provided on two adjacent outer side walls of the shell 1, and a rectangular groove 10 is formed on one of the surfaces of the shell 1.

[0024] A cover plate 2 is fixed to the housing 1 by adhesive sealing. Multiple clips 20 are formed on the lower wall of the cover plate 2. The clips 20 are structurally matched with the slots 13, with the outer ends of the clips 20 being rectangular and the inner ends being isosceles trapezoidal. When two adjacent modular sound-absorbing and insulating covers are connected, the clips 20 on the cover plate 2 are engaged in the slots 13 on one of the adjacent side walls and secured with screws.

[0025] Multiple sound insulation components 3 are placed inside the rectangular groove 10. The sound insulation components 3 are elongated and hollow, with a vacuum inside. Multiple limiting protrusions 12 are provided on both sides of the sound insulation components 3, and the limiting protrusions 12 are fixed to the bottom of the rectangular groove 10. Buffer rectangular frames 30 made of flexible material are attached to the top and bottom sides of the sound insulation components 3.

[0026] In this embodiment, when noise is blocked, the noise passes through the cover plate 2 and enters the interior of the housing 1, and then most of it enters the sound insulation component 3. Since the sound insulation component 3 is in a vacuum state, the propagation of noise is suppressed, and the cover plate 2 and the housing 1 also play a role in suppressing noise.

[0027] In this embodiment, during assembly, the clip 20 on one of the modular sound-absorbing and sound-insulating covers is clipped into the slot 13 on the adjacent modular sound-absorbing and sound-insulating cover. After connection, it is fixed with screws. Then, the connected sound-absorbing and sound-insulating panels are installed on the wall by gluing or directly using the aforementioned screws.

[0028] In some embodiments, the sound insulation component 3 has a plurality of inclined plates 31 inside, one end of the sound insulation component 3 is sealed, the other end of the sound insulation component 3 is open, and an embedded post 32 is fixed to the open end of the sound insulation component 3 by adhesive. The outer periphery of the embedded post 32 is provided with a protruding edge 34. The outer periphery of the embedded post 32 is provided with a plurality of embedded grooves 33, and the inner wall of the open end of the sound insulation component 3 is provided with a plurality of embedded blocks 320, which are embedded in the embedded grooves 33. An inner tube 36 is inserted through the inner post 32. An inner end ring 35 is located on the inner end of the inner tube 36, inside the inner post 32. A first hole 37 is formed on the inner end of the inner tube 36. A tapered hole is connected to the outer end of the first hole 37, with the outer end of the tapered hole being the larger end. A second hole 38 is connected to the outer end of the tapered hole. A third hole 39 is connected to the outer end of the second hole 38, with the inner diameter of the third hole 39 being larger than that of the second hole 38. A tightening ring 40 is threadedly connected to the outer end of the inner tube 36. The inner end of the tightening ring 40 is tightened against the outer end of the inner post 32. An end cap 41 is threaded to the outer end of the tube 36. An inner column is threaded to the inner end of the outer end of the inner tube 36. A movable rod 42 is threaded through the inner column. An inner top plate 43 is provided at the outer end of the movable rod 42. The inner wall of the end cap 41 is tightly attached to the outer end face of the inner top plate 43. A conical head 44 is provided at the inner end of the movable rod 42. The outer circumference of the inner end of the conical head 44 is tightly attached to the inner wall of the conical hole. A sealing column is provided at the inner end of the conical head 44. The sealing column passes through the first hole 37. A U-shaped groove 11 is opened on one of the inner walls of the housing 1. The end cap 41 passes through the U-shaped groove 11.

[0029] In this embodiment, during vacuuming, the operator removes the end cap 41 and pulls the movable rod 42 outward so that the conical head 44 is positioned inside the second hole 38. Then, the vacuum pump pipe is connected to the outer end of the inner tube 36, and vacuuming is performed. After completion, the pipe is removed. Subsequently, the movable rod 42 is pushed inward so that the outer circumference of the inner end of the conical head 44 is tightly pressed against the inner wall of the conical hole. Since the pressure inside the sound insulation component 3 is less than the pressure outside, the conical head 44 remains tightly pressed against the inner wall of the conical hole, thereby improving the sealing effect. Finally, the end cap 41 is screwed onto the outer end of the inner tube 36 to further improve the sealing effect.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
