Description

Technical Field

[0001] The present invention relates to the technical field of sound insulation enclosures, and in particular to a modular assembled sound insulation enclosure. Background Art

[0002] The literal meaning of a soundproof cover can be understood as a cover that isolates noise. It is often used in industrial production, construction, environmental protection projects and other fields. Please refer to the relevant content in publication numbers CN113839513A and CN103669625A. In essence, it is made of materials with sound insulation effects and placed outside high-noise equipment.

[0003] Taking equipment such as air compressors as an example, they need to be completely enclosed in a soundproof enclosure. Due to the closed nature of the enclosure, it is inconvenient to enter the enclosure when the equipment needs to be repaired. Directly disassembling the enclosure will also increase the overall maintenance time. In addition, the heat dissipation of the entire enclosure is also one of the key issues. Sometimes a specially designed ventilation system is required to cool the air inside the enclosure, otherwise it will affect the normal operation of the internal equipment. However, this will also increase process costs and increase the installation time of the enclosure.

[0004] This application proposes a solution to this problem. Summary of the Invention

[0005] The present invention aims to provide a modular assembled soundproof enclosure. Conventional soundproof enclosure structures are described below. Since most conventional soundproof enclosures are one-piece enclosed structures, it is inconvenient to enter the enclosure to perform maintenance work on the internal equipment. Directly disassembling the enclosure also increases maintenance time, and its heat dissipation method also affects its normal internal operation.

[0006] The object of the present invention can be achieved by the following technical solution: a modular assembled soundproof enclosure, comprising sound insulation panels and an assembly frame, wherein the assembly frame comprises an upper frame, a vertical bracket, and a side frame, wherein the sound insulation panels are installed in the side frames and are configured as side sound insulation panels, and the sound insulation panels are installed in the upper frame and are configured as top sound insulation panels; The vertical supports are arranged linearly along the vertical direction, the side sound insulation panels are arranged at the middle position of the vertical supports at adjacent positions, and the top sound insulation panel is arranged at the upper side position of the assembly frame; The vertical brackets and the assembly frame are provided with mounting grooves corresponding to the side frames and the upper frame. The top sound insulation panels are arranged in a mirror-symmetrical manner along the length direction of the assembly frame, and the ends of the top sound insulation panels that are close to each other are hinged, and the ends of the top sound insulation panels that are away from each other are movably connected to the assembly frame.

[0007] It is further configured as follows: the side sound insulation panels are linearly and equidistantly arranged along the length direction of the vertical bracket, and roller members corresponding to the installation slots are installed at the center point of the outer wall of the side frame and at one end of the upper frame away from each other.

[0008] It is further configured as follows: an installation notch corresponding to the side frame is opened at a lower side position of the installation slide groove in the vertical bracket.

[0009] It is further configured that the sound insulation board installed on the side frame is in an outwardly curved arch shape.

[0010] It is further configured as follows: the sound insulation boards located in the upper frame are arranged at equal intervals along the linear direction of the upper frame, and a dust collection sleeve is installed at the middle position of every four adjacent positions in the upper frame, and the sound insulation boards are curved in the direction of the corresponding dust collection sleeve.

[0011] It is further configured as follows: a vertically arranged vibration-sensitive metal sleeve is installed at the center point of the sound insulation board in the upper frame, the lower end of the vibration-sensitive metal sleeve is open, and a connecting guide rod is installed on the vibration-sensitive metal sleeve for sliding along the vertical direction, a metal billiard ball is installed on the upper end of the connecting guide rod, and an air pressure diaphragm is provided at the lower end of the connecting guide rod, and the air pressure diaphragm is installed on the inner wall of the vibration-sensitive metal sleeve.

[0012] It is further configured as follows: the number of the metal billiard balls arranged along the upper end of the vibration-sensing metal sleeve is two, and the two metal billiard balls are respectively located outside and inside the vibration-sensing metal sleeve.

[0013] It is further configured as follows: a directional block is installed at the middle position of the vibration-sensing metal sleeve corresponding to the air pressure diaphragm and the metal billiard ball, the connecting guide rod and the directional block are slidingly connected, and a connecting spring is installed at the upper end position of the connecting guide rod corresponding to the directional block.

[0014] It is further configured as follows: a plurality of directional pins are provided between two adjacent side frames in the vertical direction, an extension plate is provided at one end of the directional pin, and a screw fastener is provided at the other end of the directional pin.

[0015] The present invention has the following beneficial effects: 1. The soundproof enclosure proposed by the present invention differs significantly from conventional soundproof enclosure structures in that it is based on side and top soundproof panels, which are laid along the assembly frame to form a complete soundproof enclosure. Therefore, the overall structure is not a conventional fixed, integrated structure. Instead, the side and top soundproof panels can be folded and stored along the assembly frame or vertical brackets. This is primarily intended to facilitate subsequent maintenance operations. By folding and storing the side and top soundproof panels in a certain position, a maintenance access space is formed, eliminating the need to directly dismantle the entire soundproof enclosure structure. 2. In conjunction with the above, it is further explained that the arc shape of the external structure of the sound insulation board is used to reduce the adhesion rate of dust on the sound insulation board. The key lies in the structural shape of the top sound insulation cover. The vibration-sensitive metal sleeve is added to utilize the high-frequency vibration generated by the noise inside the sound insulation cover to accelerate the collision between the metal billiard ball and the vibration-sensitive metal sleeve by means of co-vibration, and indirectly transmit the vibration rod to the top sound insulation board. Its purpose is to accelerate the vibration of dust that may be attached to the top sound insulation board and slowly slide it into the dust collection sleeve, thereby reducing the intensity of subsequent cleaning operations.

[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: The conventional sound insulation enclosure structure is described. Since most of them are one-piece closed structures, it is inconvenient to enter the enclosure to perform maintenance work when the internal equipment needs to be repaired. If the sound insulation enclosure is directly disassembled, the maintenance time will be increased, and the heat dissipation method will also affect the normal operation of the interior. In this regard, the following technical solutions are proposed: Reference Figures 1 to 9 In this embodiment, a modular assembled soundproof enclosure includes a soundproof panel and an assembly frame 1. The assembly frame 1 includes an upper frame 101, a vertical bracket 102, and a side frame 4. The soundproof panel is installed in the side frame 4 and is configured as a side soundproof panel 3. The soundproof panel is installed in the upper frame 101 and is configured as a top soundproof panel 2. The vertical brackets 102 are arranged linearly along the vertical direction, the side sound insulation panels 3 are arranged in the middle of the adjacent vertical brackets 102, and the top sound insulation panel 2 is arranged at the upper side of the assembly frame 1; The vertical bracket 102 and the assembly frame 1 are provided with mounting grooves 103 corresponding to the side frames 4 and the upper frame 101. The top sound insulation panels 2 are arranged in a mirror-symmetrical manner along the length direction of the assembly frame 1, and the ends of the top sound insulation panels 2 that are close to each other are hinged, and the ends of the top sound insulation panels 2 that are away from each other are movably connected to the assembly frame 1. The side sound insulation panels 3 are linearly and equidistantly arranged along the length direction of the vertical bracket 102. Roller members 5 corresponding to the mounting grooves 103 are installed at the center point of the outer wall of the side frame 4 and at the end of the upper frame 101 that are away from each other. A mounting notch 104 corresponding to the side frame 4 is opened at the lower side of the mounting groove 103 in the vertical bracket 102.

[0021] Solution Description: First, combine Figure 1 、 Figure 2 and Figure 5 To illustrate, the overall structure is still based on the sound insulation board, surrounded by the side sound insulation board 3 and the top sound insulation board 2 Figure 2The assembly frame 1 shown in the figure is constructed, specifically in combination with Figure 6 To illustrate: the side sound insulation board 3 can be installed in the installation groove 103 through the installation notch 104, and after installing a side sound insulation board 3, ensure that the side sound insulation board 3 and the length of the vertical bracket 102 are kept level, so that a plurality of side sound insulation boards 3 are built to form a closed structure of the sound insulation cover, and the top sound insulation cover 2 can be directly installed in the upper frame 101, thereby forming a closed structure of the sound insulation cover. Figure 1 The structural shape displayed; The installation process of the overall structure is explained again: taking the air compressor as an example, the assembly frame 1 is installed in accordance with the structural shape of the air compressor, and the vertical bracket 102 is installed in a vertical state. Then, when the air compressor needs to be repaired, in this embodiment, it is not necessary to directly dismantle the overall structure, but refer to Figure 2 and Figure 5 The structural position shown in ; First, the side sound baffles 3 are described. According to the installation method of the side sound baffles 3 and in a bottom-to-top direction, each side sound baffle 3 is sequentially switched from a horizontal state to a vertical state. Specifically, each side sound baffle 3 is rotated 90° in the opposite direction to remain parallel to the horizontal plane. Thus, an inspection passage space for maintenance is formed between each two adjacent vertical brackets 102. For the description of the top sound insulation board 2, please refer to Figure 2 As shown, the two upper frames 101 are flipped along their hinged sections, so that the two upper frames 101 are switched from the horizontal state of the base to the horizontal state as shown. Figure 2 The herringbone shape forms a relatively open space inside the whole sound insulation enclosure, which is convenient for maintenance. After the maintenance work is completed, the side sound insulation board 3 or the top sound insulation board 2 can be quickly reset.

[0022] Example 2: Supplementary explanation of the structure and appearance of the top sound insulation board and the side sound insulation board in Example 1: The sound insulation board mounted on the side frame 4 has an outwardly curved arch shape.

[0023] Solution description: briefly explain the sound insulation board, such as Figure 3 As shown, the essence of the sound insulation board is composed of a jacket and sound insulation material. Taking the side sound insulation board 3 as an example, the outer jacket is provided with a side frame 4, and the outer jacket of the sound insulation board can be composed of a metal material, and the inner part is filled with sound insulation material. The key lies in changing the structural shape of the side sound insulation board 3. Specifically, the side sound insulation board 3 is stretched outward along the center point of the side sound insulation board 3 to form a large arc. When air dust adheres to the side sound insulation board 3, the adhesion rate of the dust on the side sound insulation board 3 is reduced. The installation method of the opposite side sound insulation board 3 needs to be explained again: Figure 4 and Figure 10 When assembling multiple side sound insulation panels 3, it is necessary to ensure the stability and strength of the overall structure. To this end, in this embodiment, a directional pin 6 is mainly set at the middle position of two adjacent side frames 4 in the vertical direction. The directional pin 6 is essentially a screw, and the difference is: An extension plate is provided at one end thereof, and a groove corresponding to the extension plate is provided on each side frame 4. When the two side frames 4 are in contact, the directional pin 6 is inserted into the joint of the two side frames 4 through the groove, and then fastened with bolts. However, before fastening, the directional pin 6 needs to be rotated 0-90 degrees. The purpose is to fasten the two adjacent side frames 4 with the extension plate on the directional pin 6, so that the directional pin 6 maintains the connection stability of the entire structure during normal use of the entire sound insulation enclosure.

[0024] Example 3: Supplementary explanation of Example 1 in combination with Example 2: A vertically arranged vibration-sensitive metal sleeve 8 is installed at the center point of the sound insulation board in the upper frame 101. The lower end of the vibration-sensitive metal sleeve 8 is open, and a connecting guide rod 11 is installed on the vibration-sensitive metal sleeve 8 in a vertical sliding direction. A metal billiard ball 9 is installed at the upper end of the connecting guide rod 11, and an air pressure diaphragm 10 is installed at the lower end of the connecting guide rod 11. The air pressure diaphragm 10 is installed on the inner wall of the vibration-sensitive metal sleeve 8; There are two metal billiard balls 9 set along the upper end of the vibration-sensing metal sleeve 8, and the two metal billiard balls 9 are respectively located outside and inside the vibration-sensing metal sleeve 8. A directional block 13 is installed at the middle position of the vibration-sensing metal sleeve 8 corresponding to the air pressure diaphragm 10 and the metal billiard balls 9. The connecting guide rod 11 and the directional block 13 are slidingly connected, and a connecting spring 12 is installed at the upper end position of the connecting guide rod 11 corresponding to the directional block 13. A plurality of directional pins 6 are arranged between the two adjacent side frames 4 in the vertical direction, an extension plate is provided at one end of the directional pin 6, and a screw fastener is provided at the other end of the directional pin 6.

[0025] Solution description: Based on the second embodiment, the top sound insulation board 2 and the side sound insulation board 3 are set in different ways, so that it is easier to adhere to the dust in the air. For this reason, the structure and shape of the top sound insulation board 2 will be improved, but the improvement method is different from the relevant content in the second embodiment. Specifically, it is shown as follows: Figure 7 For example, the top sound insulation board 2 can be composed of multiple sound insulation boards, and it is necessary to ensure that the dust collection sleeve 7 is provided in the middle of each adjacent top sound insulation board 2, and the top sound insulation board 2 needs to be bent along the direction of the dust collection sleeve 7. Under normal conditions, dust will adhere to the upper surface of the top sound insulation board 2. It should be further explained that: taking the air compressor as an example, the reason for the noise is the vibration generated by the operation of the air compressor, and the vibration is transmitted with the air. The sound insulation principle of the sound insulation board is to reduce the frequency of air vibration, thereby reducing the noise or even isolating the noise. However, in this embodiment, the air vibration inside the sound insulation cover needs to be utilized. Specifically, the air vibration is utilized. Figure 9 ; Because the vibration-sensing metal sleeve 8 is essentially made of metal material, it has the ability to transmit vibration, but the transmission ability is poor. Specifically, the lower end of the vibration-sensing metal sleeve 8 is set to an open shape, so that the air pressure diaphragm 10 therein can fluctuate slightly or significantly with the vibration of the air inside the sound insulation enclosure. The key is to change the transmission form of the connecting guide rod 11. Under normal conditions, the connecting guide rod 11, under the action of the connecting spring 12, ensures that the metal billiard ball 9 therein cooperates with the elastic action of the air pressure diaphragm 10 to be in a relatively static equilibrium state. However, when the air pressure diaphragm 10 breaks the equilibrium state of the metal billiard ball 9 due to the vibration generated by the noise inside the sound insulation enclosure, in this state, the metal billiard ball 9 will hit the vibration-sensitive metal sleeve 8 in an irregular manner, causing the vibration-sensitive metal sleeve 8 to vibrate to varying degrees. Because the outer jacket of the top sound insulation board 2 is made of metal material, it will also indirectly cause the entire top sound insulation board 2 to vibrate irregularly. The purpose is to accelerate the dust that may be attached to the top sound insulation board 2 to slide along its upper curved surface into the dust collection sleeve 7, thereby reducing subsequent dust cleaning operations.

[0026] In summary, the obvious difference from the conventional integrated sound insulation enclosure structure is that the overall structure is erected based on the assembly frame, with side sound insulation panels and top sound insulation panels as the foundation and laid along the assembly frame to form a complete sound insulation enclosure. The side sound insulation panels and top sound insulation panels can be folded and stored relative to the assembly frame, mainly used for maintenance channel space during later maintenance operations, without the need to directly dismantle the entire sound insulation enclosure structure. Based on the above content, the external structure of the sound insulation panels is first set to an arc shape. On the one hand, it is used to reduce the adhesion rate of dust on the sound insulation panels. On the other hand, based on the vibration generated by the noise inside the sound insulation enclosure, the vibration-sensitive metal sleeve is used to "accelerate" the collection of dust into the dust collection sleeve through co-vibration, thereby reducing the intensity of subsequent dust cleaning operations.

[0027] The above is merely an example and explanation of the structure of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the scope of protection of the present invention.
