Description

Technical Field

[0001] This application relates to the field of soundproof enclosure technology, and specifically discloses a detachable and convenient soundproof enclosure. Background Technology

[0002] Roof ventilators are essential equipment for ventilation in industrial plants, commercial buildings, and other similar locations. However, during operation, the rotation of the impeller and air turbulence generate significant aerodynamic noise, causing noise pollution to the surrounding environment. To address this issue, the industry commonly employs soundproof enclosures for the ventilators. These enclosures are enclosed or semi-enclosed devices specifically designed to reduce noise generated during operation, employing sound insulation, absorption, and attenuation technologies to minimize noise transmission.

[0003] Shell material: Usually made of 1.5–2mm galvanized steel plate, aluminum plate or stainless steel plate, filled with sound insulation cotton (such as 100mm thick sound-absorbing cotton) or damping layer to form an "external insulation and internal absorption" structure. This structure can effectively control the noise generated by the fan during operation inside the casing through the absorption, reflection and blocking of sound waves, significantly reducing the noise radiation to the external environment and achieving a good noise reduction and sound insulation effect.

[0004] In the existing technology, there are various kinds of soundproof enclosures, including split soundproof enclosures. However, although the existing split soundproof enclosures have solved the transportation problem, they are generally thick, heavy, costly, and have less than ideal soundproofing effect. In addition, the on-site installation workload is large, the interchangeability between parts is poor, and they cannot be repeatedly disassembled and reassembled. Therefore, there are still certain problems in production, transportation, installation and use.

[0005] In view of this, the present invention provides a detachable and convenient soundproof cover to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that traditional soundproof covers are still not convenient to install and remove.

[0007] To achieve the above objectives, this utility model provides the following basic solution: A detachable and portable soundproof enclosure includes a concrete reference surface poured based on the location of an external fan, hollow columns that are detachably connected to the concrete reference surface, slots set between adjacent hollow columns, a number of splicing plates set in the slots, and a top cover plate that is detachably connected to the top of the hollow columns. The main body of the soundproof enclosure consists of a top cover plate, a concrete reference surface, hollow columns, and splicing panels. The inner side of the splicing panel and the inner side of the hollow column are respectively provided with a first sound-absorbing module and a second sound-absorbing module.

[0008] Furthermore, locking assemblies are provided at both ends of the hollow column. Each locking assembly includes a locking screw and a locking base. The locking base contacts the concrete reference surface and the top cover plate, respectively. The locking screw passes through the locking base and connects to the concrete reference surface and the top cover plate, respectively.

[0009] Furthermore, the hollow column has operating doors at both ends.

[0010] Furthermore, the hollow column is filled with sound-absorbing cotton.

[0011] Furthermore, the first sound-absorbing module includes a porous groove on the inner side of the splicing plate and glass wool installed in the porous groove, and the second sound-absorbing module includes a porous plate fixed to the inner side of the hollow column and foam plastic installed on the porous plate.

[0012] Furthermore, the slot is fixed to the outer wall of the hollow column, and the splicing plates are stacked and placed in the slot. The splicing plate includes a main plate, a sub-plate fixed to the top of the main plate, and an insertion slot at the bottom of the main plate. When the splicing plates are stacked and placed in the slot, the sub-plate in the lower splicing plate is inserted into the insertion slot in the upper splicing plate.

[0013] Furthermore, the porous slot is formed on the motherboard.

[0014] The principle and effect of this solution are as follows: 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device is suitable for external fans and is used for sound insulation of external fans to reduce noise interference. It has the characteristics of quick disassembly, quick installation, repeated installation and high convenience.

[0015] 2. Compared with the existing technology, this device is equipped with hollow columns to act as beam structures. Based on the hollow columns, concrete reference surfaces and top cover plates, a soundproof cover is formed. The fan is covered by the soundproof cover, so that the noise emitted by the fan cannot be transmitted through the soundproof cover, thereby achieving the function of noise isolation.

[0016] 3. Compared with existing technologies, this device has outstanding advantages in terms of disassembly and assembly and ease of use. First, the hollow columns used as beams can be disassembled. The splicing plates in this device are fixed by snapping together with adjacent hollow columns. After the hollow columns are installed, the splicing plates can be installed. Finally, the splicing plates are fixed again by the top cover, making the entire soundproof enclosure structurally stable and the installation relatively firm. Attached Figure Description

Detailed Implementation

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] The reference numerals in the accompanying drawings include: concrete reference surface 1, locking screw 2, locking base 3, operating door 4, hollow column 5, main column 6, splicing plate 7, main plate 701, secondary plate 702, insertion slot 703, perforated slot 704, card slot 8, perforated plate 9, and foam plastic 901.

[0021] Implementation, for example Figures 1-5 As shown: A detachable and portable soundproof enclosure includes a concrete reference surface 1 poured based on the location of an external fan, hollow columns 5 detachably connected to the concrete reference surface 1, slots 8 set between adjacent hollow columns 5, a plurality of splicing plates 7 set in the slots 8, and a top cover plate detachably connected to the top of the hollow columns 5. Regarding concrete reference surface 1: Concrete reference surface 1 is the core of the disassembly and installation of this device. Since this device is a soundproof enclosure, it is necessary to perform sound insulation treatment on the external fan. Therefore, a concrete reference surface 1 is poured based on the position of the external fan, and the other components are quickly disassembled and assembled based on the concrete reference surface 1. The first step is the installation of the hollow column 5: locking components are provided at both ends of the hollow column 5. The locking components include locking screws 2 and locking bases 3. The locking bases 3 are in contact with the concrete reference surface 1 and the top cover plate, respectively. The locking screws 2 pass through the locking bases 3 and are connected to the concrete reference surface 1 and the top cover plate, respectively.

[0022] Before the locking screw 2 is connected to the top cover plate, the splicing plate 7 needs to be installed first. There are operating doors 4 at both ends of the hollow column 5. By manually opening the operating doors 4, the locking screw 2 can be seen after opening the operating doors 4, since it is a hollow column 5. By rotating the locking screw 2, the connection between the concrete reference surface 1 and the top cover plate can be achieved, thereby realizing the vertical installation of the hollow column 5.

[0023] After the hollow column 5 is installed vertically, sound-absorbing cotton needs to be manually filled into the interior of the hollow column 5 through the operating door 4. After filling with sound-absorbing cotton, the hollow column 5 becomes solid, which enhances the sound insulation effect of the hollow column 5.

[0024] The inner side of the splicing panel 7 and the inner side of the hollow column 5 are respectively provided with a first sound-absorbing module and a second sound-absorbing module.

[0025] Specifically: such as Figure 4 and Figure 5 As shown, the first sound-absorbing module includes a porous groove 704 opened on the inner side of the splicing plate 7 and glass wool installed in the porous groove 704. The second sound-absorbing module includes a porous plate 9 fixed to the inner side of the hollow column 5 and foam plastic 901 installed on the porous plate 9.

[0026] Specifically: the first sound-absorbing module and the second sound-absorbing module further enhance the sound absorption effect of this device.

[0027] like Figure 2 and Figure 3 As shown, the slot 8 is fixed to the outer wall of the hollow column 5. The splicing plate 7 is placed in the slot 8 with the upper and lower parts overlapping. The left and right ends of the splicing plate 7 are located in the slot 8. The splicing plate 7 includes a main plate 701, a sub-plate 702 fixed to the top of the main plate 701, and an insertion slot 703 opened at the bottom of the main plate 701. When the splicing plate 7 is placed in the slot 8 with the upper and lower parts overlapping, the sub-plate 702 in the lower splicing plate 7 is inserted into the insertion slot 703 in the upper splicing plate 7. The multi-hole slot 704 is opened on the main plate 701.

[0028] Specific implementation process: The first step is to determine the dimensions of the entire soundproof enclosure, and then determine the number of hollow columns 5. The position and layout of the hollow columns 5 are shown in Figure 2. A square layout is adopted, that is, the hollow columns 5 on both sides are side hollow columns 5, and the hollow column 5 in the middle is the main column 6. Then, the hollow columns 5 are installed vertically.

[0029] The second step involves vertically installing the hollow column 5, then placing the splicing plate 7 based on the slot 8 on the hollow column 5. The splicing plates 7 are stacked vertically, with the top of the uppermost splicing plate 7 flush with the top of the hollow column 5. The top cover is then installed using the locking assembly. From this point on, the top cover, the concrete reference surface 1, the hollow column 5, and the splicing plate 7 together form the main body of the soundproof enclosure, which provides sound insulation for the external fan.

[0030] This device solves the problem that traditional soundproof enclosures are still not convenient to install and remove.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
