Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a layered and partitioned communication power distribution cabinet. Background Art

[0002] In modern communication and power distribution systems, communication distribution cabinets are key infrastructures used to house and protect various electrical and electronic equipment. However, the existing communication distribution cabinet design still has many limitations and problems, which are mainly manifested in the following aspects:

[0003] 1. Existing communication power distribution cabinets usually adopt a full-body structure. In this structure, the entire cabinet is a whole, and various types of power distribution equipment are fixed inside by multi-layer brackets. Although this design is simple, it has significant disadvantages. First, strong and weak current equipment are in the same chamber, which is prone to safety hazards. Once a failure occurs, strong current equipment may have an adverse effect on weak current equipment, and even cause serious accidents such as fire. In addition, the mixed layout of strong and weak current will also lead to enhanced electromagnetic interference, affecting the normal operation of equipment.

[0004] 2. In the cabinet with a full-body structure, the electromagnetic interference (EMI) problem is particularly prominent because the strong and weak current equipment are in the same room. Strong current equipment will generate strong electromagnetic fields when working, which may interfere with the signal transmission and processing of weak current equipment, resulting in communication interruption or data errors. Although interference can be reduced by adding shielding measures, this will increase cost and complexity, and the effect is limited.

[0005] 3. The communication power distribution cabinet with a full-body structure also has obvious deficiencies in space utilization. Since the internal multi-layer bracket design is fixed and cannot be flexibly adjusted according to actual needs, the space utilization is low. Regardless of the number or size of the equipment, it must be installed according to the preset bracket position, and the space inside the cabinet cannot be fully utilized. This not only increases the complexity of equipment installation, but also wastes valuable cabinet space.

[0006] 4. Some communication power distribution cabinets adopt a limited partition design, dividing the internal space into several independent chambers to reduce the interference between strong and weak electricity. However, the chamber volume of this partition design is fixed and cannot be adjusted according to the number and volume of components actually assembled. This design has poor applicability and lacks flexibility and adaptability for the installation of equipment of different scales and requirements, and cannot meet diverse usage scenarios. Utility Model Content

[0007] In view of the above-mentioned deficiencies existing in the prior art, the purpose of the utility model is to provide a hierarchical and partitioned communication distribution cabinet, which solves the deficiencies of the existing communication distribution cabinet in terms of safety, electromagnetic interference, space utilization and applicability.

[0009] It also includes a plurality of interlayer units assembled in the assembly cavity and arranged in a vertical direction, the interlayer units include an assembly pad, a guide rod, a sliding bracket, an adjusting screw, and a supporting connecting rod. The corner positions of the assembly pad are slidably plugged with the guide column, and the assembly pad and the vertical projection of the assembly cavity are kept coincident. The guide rod and the adjusting screw are both assembled at the bottom of the assembly pad and kept in parallel arrangement. The sliding bracket is slidably plugged onto the guide rod and is rotationally connected to the adjusting screw. Two groups of supporting connecting rods arranged in parallel are arranged on both sides of the sliding bracket, and the two ends of the supporting connecting rod are respectively hinged to the inner wall of the wiring cavity and the sliding bracket.

[0010] In some of the implementations, in order to facilitate the assembly and maintenance of various components and testing instruments in the instrument cavity and assembly cavity, to facilitate the arrangement of cables in the wiring cavity, and to ensure the protection effect of the distribution cabinet, the following technical solutions are provided.

[0011] An upper assembly port and a lower assembly port are respectively provided on the front sides of the instrument cavity and the assembly cavity, and a rear assembly port is provided on the rear side of the wiring cavity. An upper cabinet door and a lower cabinet door are respectively hingedly provided on the upper assembly port and the lower assembly port. An inspection window is provided on the upper cabinet door, and light-transmitting glass is provided in the inspection window. The upper cabinet door and the lower cabinet door are equipped with handles, and a cover plate is fixed to the rear assembly port by bolts.

[0012] In some of the implementations, in order to facilitate the cable harness to pass into the wiring cavity for neat arrangement, to facilitate the cable harness to pass into the interlayer sub-chamber in the assembly cavity to connect with components, and to facilitate the cable harness to pass into the instrument cavity to connect with instruments, the following technical solutions are provided.

[0013] The wiring cavity is equipped with an incoming wire elbow arranged on the outside of the cabinet, the top wall of the wiring cavity is provided with a wire feeding hole A which is connected with the instrument cavity, and the inner side wall of the wiring cavity is provided with multiple groups of wire feeding holes B which are connected with the assembly cavity, and the wire feeding holes B are arranged alternately with the assembly pad.

[0014] In some implementations, in order to ensure that the assembly pad can maintain stable sliding engagement with the guide column in the assembly cavity, a guide sleeve is fixed at the corner of the assembly pad, and the guide sleeve maintains sliding engagement with the guide column.

[0015] In some implementations, in order to ensure that the cabinet can be placed stably and prevent the cabinet from directly contacting the ground, support feet are fixedly connected to the bottom corners of the cabinet.

[0016] In some of the implementations, in order to ensure that the adjusting screw and the guide rod can be stably assembled at the bottom of the assembly pad and facilitate manual operation of the adjusting screw, the following technical solutions are provided.

[0017] A rotating seat is fixedly connected to the bottom of the assembly pad, and the adjusting screw rod and the guide rod are inserted into the rotating seat in a freely rotating manner. The inner ends of the adjusting screw rod and the guide rod are fixedly connected to threaded sections, and positioning nuts are screwed on the threaded sections. The outer ends of the adjusting screw rod are fixedly connected to a handwheel.

[0018] In some of the implementations, in order to ensure that the two ends of the support connecting rod can be effectively hinged with the outer wall of the sliding bracket and the inner wall of the assembly cavity, pin bolts are inserted at both ends of the support connecting rod, and the pin bolts are screwed onto the inner wall of the assembly cavity or the side wall of the sliding bracket.

[0022] 3. The cabinet design of this application optimizes the utilization of internal space. Through flexible partition design, the chamber volume can be adjusted according to the number and volume of actual assembled components. This flexibility enables the cabinet to adapt to the installation of equipment of different scales and needs, avoids space waste, and significantly improves the space utilization efficiency of the cabinet.

[0023] 4. This application takes into account the diversity of different scenarios and needs, and significantly enhances the applicability of the cabinet through the adjustable compartment unit design.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1-5 A layered and partitioned communication distribution cabinet includes a cabinet body 1, in which an instrument cavity 11 and an assembly cavity 12 and a wiring cavity 13 arranged below the instrument cavity 11 are opened. The assembly cavity 12 is arranged in front of the wiring cavity 13, and multiple groups of vertically arranged guide columns 2 are fixedly connected in the assembly cavity 12.

[0033] It also includes a plurality of interlayer units 3 assembled in the assembly cavity 12 and arranged in the vertical direction, the interlayer units 3 include an assembly pad 31, a guide rod 32, a sliding bracket 33, an adjusting screw 34, and a supporting connecting rod 35. The corner positions of the assembly pad 31 are slidably plugged with the guide column 2, and the assembly pad 31 and the vertical projection of the assembly cavity 12 are kept coincident. The guide rod 32 and the adjusting screw 34 are both assembled at the bottom of the assembly pad 31 and kept in parallel arrangement. The sliding bracket 33 is slidably plugged onto the guide rod 32 and kept in rotation with the adjusting screw 34. Two groups of supporting connecting rods 35 arranged in parallel are arranged on both sides of the sliding bracket 33, and the two ends of the supporting connecting rod 35 are respectively hinged to the inner wall of the wiring cavity 13 and the sliding bracket 33.

[0034] The instrument cavity 11 on the top of the cabinet 1 is used to assemble various types of instrument equipment, while the assembly cavity 12 is mainly used to assemble protection elements, uninterruptible power supplies, circuit breakers, distribution units and other components of various types of communication equipment. The wiring cavity 13 is used to receive cable harnesses connected to the communication equipment, and pass them into the instrument cavity 11 and the assembly cavity 12 to connect with the components therein. The redundant cable harnesses are arranged in the wiring cavity 13, which can ensure the neatness of the instrument cavity 11 and the assembly cavity 12.

[0035] Each group of interlayer units 3 provided in the assembly chamber 12 can divide the assembly chamber 12 into multiple sub-chambers, and the volume of each sub-chamber can be adjusted by operating the corresponding interlayer unit 3 to ensure that various components of different volumes and quantities can be stably assembled in each sub-chamber.

[0036] Designing the assembly chamber 12 as multiple sub-chambers with layers and partitions can separate the high-voltage and low-voltage parts, reduce mutual interference and short-circuit risks, protect the safety of equipment and operators, and make each functional module independent, which is convenient for rapid identification of fault points and maintenance work.

[0037] Moreover, through reasonable hierarchical partitioning, the internal space of the distribution cabinet can be used more efficiently and the volume waste can be reduced. At the same time, the partitioning can reduce the electromagnetic interference between devices and ensure the stability and reliability of equipment operation.

[0038] The communication distribution cabinet with layered partition design provided in this application not only improves the working efficiency and safety of the distribution cabinet, but also simplifies the installation and maintenance process of the equipment.

[0039] The height adjustment of the interlayer unit 3 in the assembly cavity 12 follows the following principle. The setting of the guide column 2 limits each assembly pad 31 to be able to move stably up and down only in the vertical direction. The adjusting screw 34 and the guide rod 32 are arranged along the opening direction of the cabinet 1. When the adjusting screw 34 is driven to operate, the sliding bracket 33 can be driven to slide stably along the length direction of the guide rod 32, and then the lifting and lowering movement of the loading pad is driven by the supporting connecting rod 35. Since two sets of parallel supporting connecting rods 35 are arranged on both sides of the sliding bracket 33, the supporting effect of the assembly pad 31 can be improved, and then the volume of each sub-chamber in the assembly cavity 12 can be adjusted to ensure that the relevant components are stably installed on each layer of the assembly pad 31, and the internal space of the assembly cavity 12 is reasonably used.

[0040] In order to facilitate the assembly and maintenance of various components and testing instruments in the instrument cavity 11 and the assembly cavity 12, to facilitate the arrangement of cables in the wiring cavity 13, and to ensure the protection effect of the distribution cabinet, the following technical solutions are provided.

[0041] An upper assembly port and a lower assembly port 121 are respectively provided on the front sides of the instrument cavity 11 and the assembly cavity 12, and a rear assembly port 131 is provided on the rear side of the wiring cavity 13. An upper cabinet door 112 and a lower cabinet door 122 are respectively hingedly mounted on the upper assembly port and the lower assembly port 121. An inspection window 113 is provided on the upper cabinet door 112, and light-transmitting glass is installed in the inspection window 113. The upper cabinet door 112 and the lower cabinet door 122 are equipped with handles, and a cover plate 132 is fixed to the rear assembly port 131 by bolts.

[0042] The design of the upper assembly port, the lower assembly port 121 and the rear assembly port 131 can ensure the assembly, maintenance and wiring operations of the components, cable harnesses and instruments in the instrument cavity 11, the assembly cavity 12 and the wiring cavity 13.

[0043] Since the instrument chamber 11 and the assembly chamber 12 are opened and closed frequently, the upper cabinet door 112 and the lower cabinet door 122 are installed in a hinged manner to facilitate the control of their opening and closing. The wiring chamber 13 is usually only opened for wiring during the assembly stage of the distribution cabinet, so the rear cover plate 132 is installed by bolt fixing.

[0044] In order to facilitate the cable harness to pass into the wiring cavity 13 for neat arrangement, to facilitate the cable harness to pass into the interlayer sub-chamber in the assembly cavity 12 for connection with components, and to facilitate the cable harness to pass into the instrument cavity 11 for connection with instruments, the following technical solution is provided.

[0045] The wiring cavity 13 is equipped with an incoming wire bend pipe 133 arranged on the outside of the cabinet 1, and a wire feeding hole A134 connected to the instrument cavity 11 is opened on the top wall of the wiring cavity 13. A plurality of wire feeding holes B135 connected to the assembly cavity 12 are opened on the inner wall of the wiring cavity 13, and the wire feeding holes B135 are arranged alternately with the assembly pad 31.

[0046] The downward curved design of the incoming wire bend 133 can prevent rain and dust in the external environment from entering the wiring cavity 13 along the incoming wire bend 133. The setting of the wire feeding hole A134 can ensure that the cable harness in the wiring cavity 13 is stably transported to the instrument cavity 11, and the wire feeding hole B135 arranged alternately with the interlayer assembly pad 31 can stably transport the cable harness in the wiring cavity 13 to each sub-chamber in the assembly cavity 12.

[0047] In order to ensure that the assembly pad 31 can maintain a stable sliding connection with the guide column 2 in the assembly cavity 12, a guide sleeve 311 is fixedly connected to the corner of the assembly pad 31, and the guide sleeve 311 maintains a sliding connection with the guide column 2.

[0048] The guide sleeve 311 is arranged to be slidably connected with the guide column 2. When the position of the sliding bracket 33 is adjusted and the height of the assembly pad 31 is adjusted through the supporting connecting rod 35, the guide sleeve 311 always ensures the stable lifting and lowering of the assembly pad 31 in the vertical direction.

[0049] In order to ensure that the cabinet body 1 can be placed stably and prevent the cabinet body 1 from directly contacting the ground, support feet 14 are fixedly connected to the bottom corners of the cabinet body 1 .

[0050] The support legs 14 can ensure that the cabinet 1 is placed stably, and can lift the cabinet 1 to make the bottom hollow, thereby preventing water on the ground from directly invading the interior of the cabinet 1 and causing damage to the components assembled in the cabinet 1.

[0051] In order to ensure that the adjusting screw rod 34 and the guide rod 32 can be stably assembled at the bottom of the assembly pad 31 and facilitate manual operation of the adjusting screw rod 34, the following technical solution is provided.

[0052] A rotating seat 312 is fixedly connected to the bottom of the assembly pad 31, and the adjusting screw rod 34 and the guide rod 32 are inserted into the rotating seat 312 in a freely rotatable manner. The inner ends of the adjusting screw rod 34 and the guide rod 32 are fixedly connected to threaded sections, and a positioning nut 361 is screwed on the threaded section. The outer end of the adjusting screw rod 34 is fixedly connected to a handwheel 341.

[0053] The rotating seat 312 is provided with two rows, each row has three groups, the rotating seat 312 in the middle position of the two rows is used to install the adjusting screw 34, and the rotating seat 312 on the two sides of the two rows is used to install two groups of guide rods 32, the outer diameter of the threaded section is smaller than the outer diameter of the guide rod 32 and the adjusting screw 34, and is arranged in a stepped shape with the guide rod 32 or the adjusting screw 34 to ensure that the positioning nut 361 screwed onto the threaded section can lock and position the guide rod 32 and the adjusting screw 34, and ensure that the guide rod 32 and the adjusting screw 34 can only rotate around their own axis.

[0054] When the driving hand wheel 341 is running, the adjusting screw rod 34 can be driven to run stably, thereby driving the sliding bracket 33 to slide smoothly within the travel range of the guide rod 32 .

[0055] To ensure that both ends of the support link 35 can be effectively hinged with the outer wall of the sliding bracket 33 and the inner wall of the assembly cavity 12, pin bolts 362 are inserted at both ends of the support link 35, and the pin bolts 362 are screwed to the inner wall of the assembly cavity 12 or the side wall of the sliding bracket 33.

[0056] The pin bolt 362 can effectively position the support link 35 so that the support link 35 can only rotate around the pin bolt 362 to ensure that the support link 35 can effectively push the corresponding assembly pad 31 to move up and down.
