Description

Technical Field

[0001] This invention relates to the field of soundproof wall installation technology, and more specifically, to modular soundproof walls for rail transit control rooms and their assembly devices and methods. Background Technology

[0002] The vehicle control room is the "brain" and "nerve center" of rail transit operations, undertaking core tasks such as train monitoring, dispatching and command, and emergency response. A quiet, undisturbed acoustic environment is crucial for operators to maintain high concentration, avoid misjudgments, and reduce work pressure. However, the existing wall structure and installation methods of vehicle control rooms have many technical defects, making it difficult to meet the increasingly stringent acoustic and maintenance requirements.

[0003] Traditional control room walls are typically constructed on-site using a lightweight steel frame filled with sound-absorbing cotton, then covered with plasterboard or metal panels. This construction suffers from sound bridging effects and inadequate sealing, resulting in poor isolation of low- and mid-frequency noise from the platform and track area. Furthermore, the installation of existing modular walls usually relies on manual handling to align adjacent panels before assembly using installation tools, which is both time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to address the problems of poor sound insulation and time-consuming and labor-intensive installation of modular soundproof walls in rail transit control rooms.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: Modular soundproof wall panel for rail transit control room, including wall panel, wherein the wall panel includes two base plates and two sound-absorbing plates disposed between the two base plates; The noise reduction assembly includes a vacuum chamber inside the noise reduction plate, and includes several fixed shafts disposed on the inner wall of the vacuum chamber and several refractive plates disposed alternately on the fixed shafts.

[0006] As a preferred technical solution of this application, a reinforcing frame is provided between the two sound-absorbing plates.

[0007] As a preferred technical solution of this application, the substrate and the sound-absorbing plate are provided with a reserved gap on the opposite side, and the reserved gap is filled with sound-absorbing cotton.

[0008] This application also discloses an assembly device, including the aforementioned modular soundproof wall panel for a rail transit vehicle control room, comprising: Support components installed on the wall panels are used to guide two adjacent wall panels; A connecting component installed inside the wall panel is used to self-lock two wall panels that are pressed together. The sealing assembly installed on the wall panel is used to seal the joint between two spliced ​​wall panels.

[0009] As a preferred technical solution of this application, the support assembly includes a sliding column slidably disposed on one side of the top and bottom of the wall panel, a sliding seat disposed at the end of the sliding column away from the wall panel, and a first spring disposed between the sliding column and the interior of the wall panel. The top and bottom of the end of the wall panel away from the sliding column are provided with sliding grooves that cooperate with the sliding seat.

[0010] As a preferred technical solution of this application, the connecting assembly includes a post disposed on the side wall of the wall panel, a locking post slidably disposed inside the wall panel, and a second spring disposed between the locking post and the inner wall of the wall panel. The side wall of the wall panel is provided with a slot that cooperates with the post, and the side wall of the post is provided with a limiting groove that cooperates with the locking post.

[0011] As a preferred technical solution of this application, the connecting assembly further includes a guide post disposed at the end of the locking post and extending through the wall panel into the interior of the slide groove.

[0012] As a preferred technical solution of this application, the sealing assembly includes a first fixing plate disposed at one edge of the wall panel, a second fixing plate disposed at the other edge of the wall panel, a sealing strip disposed on the side wall of the first fixing plate, and a sealing groove formed on the side wall of the second fixing plate and cooperating with the sealing strip.

[0013] As a preferred technical solution of this application, a rubber plug is provided on one side of the wall panel, and a groove that cooperates with the rubber plug is provided on the other side of the wall panel.

[0014] This application also discloses an assembly method applied to the above-mentioned assembly device, comprising the following steps: S10: First, align the two wall panels that need to be spliced. The two wall panels can be fastened together by the set support components, so that the two wall panels are temporarily connected and at the same height. S20: Slide two adjacent wall panels to make their side walls abut together. At this time, the two abutting wall panels can be automatically locked together by the connecting components. S30: When two adjacent wall panels are spliced ​​together, the sealing components can seal the joint between the two wall panels, thus sealing the installed wall panels. S40: In addition, when two adjacent wall panels are spliced ​​together, the rubber plug on the side wall of one wall panel will be inserted into the groove on the side wall of the other wall panel to reduce the stress caused by the expansion and contraction of the wall panels and prevent cracking.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By creating a vacuum cavity in the sound-absorbing panel, sound cannot propagate in a vacuum environment, thus achieving a sound insulation effect. In addition, the sound-absorbing components can refract sound waves when noise penetrates into the wall panel, dissipating sound wave energy and further improving the sound insulation effect. This solves the problem that existing technologies cannot completely eliminate sound by using only sound-absorbing materials.

[0016] When splicing wall panels, adjacent wall panels can be pre-clamped together and placed at the same horizontal height using the set support components. This allows the two wall panels to slide horizontally relative to each other and maintain alignment, which is convenient for subsequent assembly. This solves the problem of time-consuming and labor-intensive work that requires workers to lift the wall panels to keep them aligned, as is the case in the prior art.

[0017] After the two wall panels are joined together, the connecting components can self-lock the joined wall panels without the need for installation tools, making the operation simple and time-saving. At the same time, the sealing components can seal the joint between the two wall panels after assembly, preventing liquids or foreign objects from entering the gap between the wall panels.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] like Figure 1 and Figure 2 As shown, this embodiment proposes a modular soundproof wall for a rail transit vehicle control room, including a wall panel 1 and a sound-absorbing component 2. The wall panel 1 includes two base plates 101 and two sound-absorbing plates 102 disposed between the two base plates 101. A vacuum cavity 1021 is opened inside the sound-absorbing plate 102. The sound-absorbing component 2 includes a plurality of fixed shafts 201 disposed on the inner wall of the vacuum cavity 1021 and a plurality of refractive plates 202 disposed alternately on the fixed shafts 201. When noise is transmitted into the interior of wall panel 1, it enters the vacuum cavity 1021 inside the sound-absorbing plate 102. Since sound cannot travel in a vacuum, it can achieve a sound insulation effect. Moreover, after the sound waves enter the vacuum cavity 1021, they can be reflected by the refracting plates 202 with staggered angles, so that the energy of the sound wave transmission is consumed, thereby further improving the sound insulation effect of wall panel 1.

[0022] A reinforcing frame 103 is provided between the two sound-absorbing panels 102; the reinforcing frame 103 can improve the hardness of the wall panel 1 and prevent the wall panel 1 from being damaged by impacts from external objects.

[0023] The substrate 101 and the sound-absorbing plate 102 have a reserved gap on their opposite sides, and the reserved gap is filled with sound-absorbing cotton; the sound-absorbing cotton can further improve the sound insulation effect of the wall panel 1.

[0024] like Figures 3 to 6As shown, this embodiment also proposes an assembly device, including the modular soundproof wall panel of the rail transit vehicle control room in any of the above embodiments, including a support component 3, a connecting component 4 and a sealing component 7. The support component 3 is disposed on the wall panel 1 and is used to guide two adjacent wall panels 1. The connecting component 4 is disposed inside the wall panel 1 and is used to self-lock two abutting wall panels 1. The sealing component 7 is disposed on the wall panel 1 and is used to seal the joint of two spliced ​​wall panels 1. When wall panels 1 need to be spliced, the two adjacent wall panels 1 are first fastened together by the support component 3, so that the two adjacent wall panels 1 are at the same height and can slide horizontally relative to each other. Therefore, the wall panels 1 can be accurately aligned without the need for manual lifting. Then, the wall panels 1 are slid together so that the two wall panels 1 abut against each other. At this time, the two abutting wall panels 1 can be locked together by the connecting component 4. No other installation tools are needed, saving time. Finally, the sealing component 7 can seal the connection between the two wall panels 1 after installation to prevent liquids or foreign objects from entering the gap between the wall panels 1 and causing damage to the wall panels.

[0025] like Figure 7 and Figure 10 As shown, in a preferred embodiment, based on the above method, the support component 3 further includes a sliding column 301 slidably disposed on one side of the top and bottom of the wall panel 1, a sliding seat 302 disposed at the end of the sliding column 301 away from the wall panel 1, and a first spring 303 disposed between the sliding column 301 and the interior of the wall panel 1. The top and bottom of the end of the wall panel 1 away from the sliding column 301 are provided with sliding grooves 5 that cooperate with the sliding seat 302. First, place the two wall panels 1 at the same height. Then, pull out the sliding columns 301 at the top and bottom of one wall panel 1 and make the sliding seat 302 at the end of the sliding column 301 engage with the sliding groove 5 at the top and bottom of the other wall panel 1, so that the two wall panels 1 can be temporarily fastened together. Therefore, it is not necessary for workers to keep lifting the two wall panels 1 to maintain the same height.

[0026] like Figure 8 and Figure 11 As shown, in a preferred embodiment, based on the above method, the connecting component 4 further includes a post 401 disposed on the side wall of the wall panel 1, a locking post 402 slidably disposed inside the wall panel 1, and a second spring 403 disposed between the locking post 402 and the inner wall of the wall panel 1. The side wall of the wall panel 1 is provided with a slot that cooperates with the post 401, and the side wall of the post 401 is provided with a limiting groove 4011 that cooperates with the locking post 402. The connecting assembly 4 also includes a guide post 404 disposed at the end of the locking post 402 and extending through the wall panel 1 into the interior of the slide groove 5; When one wall panel 1 slides against another wall panel 1, the insert post 401 on the side wall of one wall panel 1 will insert into the slot on the side wall of the other wall panel 1. When the insert post 401 contacts the locking post 402, it will push the locking post 402 upward and compress the second spring 403. When the two wall panels 1 are completely against each other, the limiting groove 4011 on the insert post 401 will move to the position where the locking post 402 is aligned. At this time, the second spring 403 will spring the locking post 402 into the limiting groove 4011 and lock the insert post 401. At this time, the two wall panels 1 after being against each other can be automatically fixed without the need for additional installation tools. The operation is simple and saves time. When the wall panel 1 needs to be disassembled, replaced or maintained, simply pull the guide post 404 that extends into the sliding groove 5 outward to pull the locking post 402 to move away from the insert post 401. At this time, the wall panel 1 can be separated for disassembly.

[0027] like Figure 4 , Figure 5 and Figure 9 As shown, in a preferred embodiment, based on the above method, the sealing assembly 7 further includes a first fixing plate 701 disposed on one side edge of the wall panel 1, a second fixing plate 702 disposed on the other side edge of the wall panel 1, a sealing strip 703 disposed on the side wall of the first fixing plate 701, and a sealing groove 704 formed on the side wall of the second fixing plate 702 and cooperating with the sealing strip 703. After the two wall panels 1 are installed together, the first fixing plate 701 on one wall panel 1 will abut against the second fixing plate 702 on the other wall panel 1. Because the sealing strip 703 is made of rubber, the sealing strip 703 on the first fixing plate 701 will be forced into the sealing groove 704 on the second fixing plate 702 under pressure, which can seal the gap at the abutment of the two wall panels 1 and prevent liquid or foreign objects from entering the gap between the wall panels 1 and causing damage to the wall panels 1.

[0028] In addition, a rubber plug 6 is provided on one side of the wall panel 1, and a groove 601 that cooperates with the rubber plug 6 is provided on the other side of the wall panel 1. After the two wall panels 1 come into contact, the rubber plug 6 will also be squeezed into the groove 601. On the one hand, it can prevent water seepage, and on the other hand, it can reduce the stress caused by the expansion and contraction of the wall and avoid cracking.

[0029] The present invention also discloses an assembly method, applied to the assembly device in any of the above embodiments, comprising the following steps: S10: First, align the two wall panels 1 that need to be spliced. The two wall panels 1 can be fastened together by the set support component 3, so that the two wall panels 1 are temporarily connected and at the same height. S20: Slide two adjacent wall panels 1 so that the side walls of the two wall panels 1 abut against each other. At this time, the two wall panels 1 that abut against each other can be automatically locked together by the connecting component 4. S30: When two adjacent wall panels 1 are spliced ​​together, the sealing component 7 can seal the joint between the two wall panels 1, thus sealing the installed wall panel 1. S40: In addition, when two adjacent wall panels 1 are spliced ​​together, the rubber plug 6 on the side wall of one wall panel 1 will be inserted into the slot 601 on the side wall of the other wall panel 1 to reduce the stress caused by the expansion and contraction of the wall panel 1 and prevent cracking.

[0030] The working principle of this invention is as follows: When noise is transmitted into the interior of wall panel 1, it enters the vacuum cavity 1021 inside the sound-absorbing plate 102. Since sound cannot propagate in a vacuum, a sound insulation effect can be achieved. Moreover, after the sound waves enter the vacuum cavity 1021, they are reflected by the staggered refracting plates 202, which dissipates the energy of the transmitted sound waves, thereby further improving the sound insulation effect of wall panel 1. When wall panels 1 need to be spliced, the two wall panels 1 are first placed at the same height. Then, the sliding columns 301 at the top and bottom of one wall panel 1 are pulled outward, and the sliding seats 302 at the ends of the sliding columns 301 are engaged in the sliding grooves 5 at the top and bottom of the other wall panel 1, so that the two wall panels 1 can be temporarily fastened together. Therefore, it is not necessary for workers to keep the two wall panels 1 raised to maintain the same height. At this point, one wall panel 1 slides to abut against another wall panel 1. The insert post 401 on the side wall of one wall panel 1 will then insert into the slot on the side wall of the other wall panel 1. When the insert post 401 contacts the locking post 402, it will push the locking post 402 upward and compress the second spring 403. When the two wall panels 1 are completely abutted, the limiting groove 4011 on the insert post 401 will move to the position where the locking post 402 is aligned. At this point, the second spring 403 will spring the locking post 402 into the limiting groove 4011 and lock the insert post 401. The two wall panels 1 are then automatically fixed after abutting, without the need for additional installation tools. The operation is simple and saves time. After the two wall panels 1 are installed together, the first fixing plate 701 on one wall panel 1 will abut against the second fixing plate 702 on the other wall panel 1. Because the sealing strip 703 is made of rubber, the sealing strip 703 on the first fixing plate 701 will be forced into the sealing groove 704 on the second fixing plate 702 under pressure, which can seal the gap at the abutment of the two wall panels 1 and prevent liquid or foreign objects from entering the gap between the wall panels 1 and causing damage to the wall panels 1.

[0031] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
