Description

Technical Field

[0001] This utility model relates to the field of low-voltage communication cabinet technology, and in particular to a novel low-voltage communication cabinet. Background Technology

[0002] A low-voltage interconnection cabinet is an electrical device used in low-voltage power distribution systems. It is mainly used to switch between two power sources, usually the main power source and the backup power source, to ensure the continuity and reliability of power supply. It plays a role in connecting, controlling and protecting circuits in the power distribution system and is suitable for industrial plants, commercial buildings and public facilities.

[0003] In existing technologies, the internal structure of low-voltage tie cabinets is usually quite compact, containing multiple electrical components such as circuit breakers, disconnect switches, busbars, terminals, and complex wiring connections. Since most of these components are concentrated in fixed positions inside the cabinet, and existing low-voltage tie cabinets generally only have one front-opening maintenance door, this means that personnel can only approach the equipment from the front when performing maintenance or repair operations, resulting in very limited operating space. This structural design not only makes it difficult for maintenance personnel to fully observe the working status and connection of internal components, but also increases the difficulty of wiring, replacing parts, or troubleshooting, easily leading to misoperation or inadequate maintenance. In addition, the limited operating space also prolongs maintenance time, reduces operation and maintenance efficiency, and may even affect the stability and safety of the power supply system due to untimely maintenance. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of limited space during maintenance of existing communication cabinets, and to propose a new type of low-voltage communication cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel low-voltage communication cabinet includes a communication cabinet body. The communication cabinet body has an installation opening on its side wall and an installation door adapted to the installation opening. Both side walls of the communication cabinet body are provided with maintenance components. Each maintenance component includes a maintenance opening on the side wall of the communication cabinet body. The maintenance opening has a sliding groove inside. The maintenance opening and the sliding groove are both provided with a roller door, and the roller door is slidably connected to the sliding groove.

[0007] As a preferred technical solution of this utility model, the maintenance assembly further includes a drive component for controlling the rolling door. The drive component includes a cavity disposed inside the communication cabinet body, a roller rotating inside the cavity, a motor installed inside the cavity, the end of the output shaft of the motor being axially connected to the free end of the roller, and one side of the rolling door being fixed to the roller.

[0008] As a preferred technical solution of this utility model, the fastener includes a fastening groove 1 disposed inside the slide groove, an airbag 1 fixed inside the fastening groove 1, a fastening groove 2 disposed on the side wall opposite the mounting opening and the mounting door, an airbag 2 fixed inside the fastening groove 2, and a connecting pipe connected to the airbag 1.

[0009] As a preferred embodiment of this utility model, the side wall of the communication cabinet body is provided with a drain outlet, which is connected to the slide groove.

[0010] As a preferred embodiment of this utility model, the inner bottom surface of the slide is inclined.

[0011] As a preferred embodiment of this utility model, a counterweight is fixed at the bottom of the roller door, and the counterweight is slidably connected to the slide groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. Provides multiple maintenance access points, effectively improving maintenance operation space: This solution breaks through the limitation of traditional low-voltage communication cabinets relying solely on the front maintenance door by setting up openable roller door maintenance ports on both side walls of the communication cabinet body. Staff can choose to carry out maintenance work from the side according to actual needs, avoiding the inconvenience caused by dense internal components and limited space in front, significantly improving visibility, operational flexibility and maintenance efficiency during the maintenance process, and reducing the risk of misoperation.

[0014] 2. The airbag linkage sealing system enhances protection performance and adapts to harsh outdoor environments: This solution uses airbag one and airbag two to form a linkage sealing structure through connecting pipes. When the installation door is closed, airbag two expands under pressure and transfers gas to airbag one, thereby tightly squeezing the edges and bottom of the roller door and improving the overall sealing performance. This design can effectively prevent dust, rainwater and other external impurities from entering the cabinet and enhance the environmental adaptability of the equipment.

[0015] 3. Rational overall structural layout: Without increasing the external volume too much, this solution makes reasonable use of the internal space of the cabinet to arrange key components such as cavities, rollers, and motors, making the overall structure more compact and beautiful. Moreover, the roller door does not expand outward when opened and will not occupy additional side space, making it suitable for use in places with limited installation space. It has strong practicality and promotional value. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A novel low-voltage communication cabinet includes a cabinet body 1. The cabinet body 1 has an installation opening 2 on its side wall. The cabinet body 1 has an installation door 3 adapted to the installation opening 2, which is connected to the cabinet body 1 via a hinge. Both side walls of the cabinet body 1 are equipped with maintenance components, including maintenance openings 4 on the side walls of the cabinet body 1. The inner side of the maintenance opening 4 has a sliding groove 6 with a U-shaped longitudinal section. The maintenance opening 4 and the sliding groove 6 share a common interior with a roller shutter 5. Both sides of the roller door 5 are slidably connected to the slide rail 6. Furthermore, a counterweight 16 is fixed at the bottom of the roller door 5. The counterweight 16 is slidably connected to the slide rail 6. When the roller door 5 is extended, the counterweight 16 can improve the stability and smoothness of the roller door 5 movement. Furthermore, the side wall of the communication cabinet body 1 is provided with a drain outlet 15. The drain outlet 15 is connected to the slide rail 6. The inner bottom surface of the slide rail 6 is inclined. In this way, when the device is placed outdoors, rainwater will enter the bottom of the slide rail 6 along the roller door 5 and then be discharged through the drain outlet 15.

[0023] Furthermore, the maintenance assembly also includes a drive unit for controlling the rolling door 5. The drive unit includes a cavity 7 disposed inside the communication cabinet body 1. A roller 9 rotates inside the cavity 7. A motor 8 is installed inside the cavity 7. The output shaft end of the motor 8 is axially connected to the free end of the roller 9. One side of the rolling door 5 is fixed to the roller 9. The motor 8 controls the rotation of the roller 9 to realize the release and retraction of the rolling door 5.

[0024] Furthermore, the fasteners include a fastening groove 10 located inside the slide groove 6, which is opposite to the roller door 5. An airbag 11 is fixed inside the fastening groove 10. A fastening groove 2 is provided on the side wall opposite the mounting door 3. An airbag 23 is fixed inside the fastening groove 2. The airbag 23 has a U-shaped structure and a connecting pipe 14 is connected to it. The connecting pipe 14 is connected to the airbag 11. When the mounting door 3 is closed, the airbag 23 will be squeezed, causing the airbag 11 to expand and squeeze the side and bottom of the roller door 5. With this design, the airbag 11 can improve the sealing of the roller door 5, and the airbag 23 can improve the sealing of the mounting door 3, thereby improving the overall protective performance of the device.

[0025] The specific working principle of this utility model is as follows:

[0026] When maintenance is required, the operator opens the installation door 3, leaving the installation opening 2 open. Simultaneously, the second airbag 13 is no longer compressed by the installation door 3. Under its own elasticity, the second airbag 13 draws air from the first airbag 11, causing the first airbag 11 to contract and no longer exert pressure on the roller door 5. Then, the motor 8 is started, driving the roller 9 to rotate, allowing the roller door 5 to wind around the roller 9, thus opening the inspection opening 4. At this point, the operator can observe and perform maintenance through the side inspection opening 4. Conversely, after maintenance is completed, the roller door 5 is released by the motor 8, so that the maintenance port 4 is closed. Then the installation door 3 is closed, and the installation door 3 compresses the second airbag 13, so that some of the air inside it enters the first airbag 11 through the connecting pipe 14. The first airbag 11 inflates and expands, thereby compressing the roller door 5 and improving the sealing of the device. Under this design, the staff can carry out maintenance on the inside of the device from the side, which improves the flexibility and convenience of operation. Moreover, the roller door 5 does not occupy the space on the side of the device when it is opened, which further improves the practicality of the device.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
