Description

Technical Field

[0001] The present invention relates to the technical field of power distribution equipment, and in particular to an AC power distribution box for a communication base station. Background Art

[0002] As a key node of the information network, the uninterrupted operation of the communication base station is the cornerstone to ensure the continuity and overall reliability of the communication network. The AC distribution box, as the core component of the power supply system of the communication base station, is responsible for the safe access and efficient distribution of the front-end AC power.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] Communication base stations are key nodes of information networks, and their continuous and stable operation is crucial. As the core of the power supply of base stations, AC distribution boxes are responsible for the safe access and efficient distribution of AC power. They have functions such as AC input, precise output, power metering and lightning protection, and provide stable power for communication equipment.

[0023] Traditional distribution boxes have a single function. When a fault occurs, they can only be repaired by manually cutting off the power supply, which has a slow response speed. Regular manual maintenance and inspections increase operation and maintenance costs, and traditional power-off maintenance may cause communication base stations to stop operating, resulting in data loss and service interruption, affecting user experience and business continuity.

[0024] Based on the existing technical problems, the present invention provides an AC distribution box for a communication base station to ensure the reliability of power distribution; Figures 1 to 10 As shown, an AC distribution box for a communication base station includes: The box body 1 includes a door panel 11 arranged at the front end, and input lines 12 and output lines 13 at the upper and lower ends; the box body 1 serves as an outer shell to protect the internal components from the external environment, the door panel 11 is convenient for maintenance operations, and the input lines 12 and output lines 13 are respectively arranged at the upper and lower ends of the box body 1 for easy power access.

[0025] The switchboard 3 is used for input power distribution, as well as circuit protection, monitoring and control. The switching mechanism 4 is used for connecting the input line 12 and the switchboard 3. The switchboard 3 and the switching mechanism 4 are both arranged in the box 1. The switchboard 3 is provided with two groups of switching mechanisms 4 corresponding to the switchboard 3. The input line 12 is connected to any switchboard 3 through the switching mechanism 4. The two groups of switchboards 3 provided in the present invention are flexibly connected to the input line 12 through the switching mechanism 4. When any switchboard 3 fails, the switching mechanism 4 enables the other switchboard 3 to independently access the power supply, thereby improving the flexibility and reliability of the power distribution system.

[0026] Example 1 In this embodiment, if Figures 2 to 4 As shown, inside the box 1 of the AC distribution box, the switching mechanism 4 corresponding to the input line 12 is fixedly arranged on the top of the inner wall of the box 1, and the two relatively arranged distribution boards 3 are respectively located on both sides of the width of the box 1, and can be moved out of the box 1 respectively with the help of the track structure to facilitate fault inspection and maintenance.

[0027] like Figure 2 As shown, a mounting box 14 is provided on the top inner wall of the box body 1, and the adapter mechanism 4 is provided on the top of the box body 1 and is located in the mounting box 14; in the present invention, the adapter mechanism 4 obtains driving force through induced current and electromagnetic induction, and the mounting box 14 is used to isolate the static electricity and the influence of other electrical components or environmental factors in the box body 1 on the adapter mechanism 4, and at the same time, the mounting box 14 provides an installation space for some structures in the adapter mechanism 4.

[0028] Two sets of switchboards 3 are arranged on both sides of the door panel 11 in the width direction, and are respectively moved in a direction perpendicular to the door panel 11 by means of movable brackets 5. Movable blocks 15 are arranged on the inner wall of the box body 1 on the side close to the door panel 11, corresponding to the switchboards 3. The movable brackets 5 enable the switchboards 3 to be easily moved out of or into the box body 1, which is convenient for maintenance and replacement; the movable blocks 15 are used to limit the switchboards 3 and limit and fix their installation position in the box body 1, so as to ensure the stability and safety of the power distribution system in the box body 1.

[0029] like Figure 3 As shown, the movable bracket 5 includes a first connecting seat 51 and a second connecting seat 52 which are symmetrically arranged, and a mounting plate 53 located therebetween, and the distribution board 3 is arranged on the mounting plate 53; the first connecting seat 51 and the second connecting seat 52 have the same structure and are respectively fixed to the top and the bottom of the box body 1, and the mounting plate 53 is slidably connected to the box body 1 through the first connecting seat 51 and the second connecting seat 52.

[0030] The symmetrically arranged first connecting seat 51 and second connecting seat 52 provide stable support and sliding guidance for the mounting plate 53 , so that the switchboard 3 can stably move in a direction perpendicular to the door panel 11 .

[0031] Specifically, Figure 4 As shown, the first connecting seat 51 includes a fixed guide rail 511, a sliding seat 512 and a movable guide rail 513. The mounting plate 53 is fixedly connected to the movable guide rail 513 and is slidingly connected to the sliding seat 512 through the movable guide rail 513. The sliding seat 512 is also slidingly connected to the fixed guide rail 511, and the fixed guide rail 511 is fixed to the inner wall of the box body 1.

[0032] A first rack 514 , a gear 515 and a second rack 516 are respectively provided on the same side of the fixed guide rail 511 , the sliding seat 512 and the movable guide rail 513 . The gear 515 is rotatably connected to the sliding seat 512 and meshes with the first rack 514 and the second rack 516 .

[0033] The fixed guide rail 511 is fixedly connected to the box body 1, providing a stable sliding track for the sliding seat 512, and the sliding seat 512 drives the mounting plate 53 to move through the movable guide rail 513; when the gear 515 on the sliding seat 512 rotates, the sliding seat 512 and the movable guide rail 513 can be driven to move along the length direction of the fixed guide rail 511 through the meshing first rack 514 and the second rack 516, thereby realizing the precise movement of the distribution board 3; the stability and accuracy of the distribution board 3 during the movement are ensured by the three-layer sliding structure.

[0034] Example 2 In this embodiment, if Figures 5 to 10 As shown, the switching mechanism 4 uses the electromagnetic principle to obtain the driving force during the switching process of the two distribution boards 3. Specifically, the switching mechanism 4 includes a swing frame 43 and a connecting vessel 45 connected to one end thereof, the swing frame 43 is rotatably connected to the fixed seat 41 through a connecting shaft 42, the connecting vessel 45 is arranged on the support beam 44 and slidably connected thereto, the connecting shaft 42 is arranged corresponding to the middle part of the support beam 44, and its rotation axis is perpendicular to the length direction of the support beam 44; two distribution switches 2 are arranged at both ends of the length close to the support beam 44 respectively corresponding to the two groups of distribution boards 3, the distribution switch 2 includes a first connection board 21 and a second connection board 22 respectively connecting the input line 12 and the distribution board 3, and the connecting vessel 45 includes an input end 451 and an output end 452 respectively arranged corresponding to the first connection board 21 and the second connection board 22.

[0035] Furthermore, the communicating vessel 45 also includes a conductive wire 453 connecting the input end 451 and the output end 452, and an induction coil 454 arranged on the outer circle of the conductive wire 453, the conductive wire 453 includes a first wire and a second wire respectively connecting the neutral wire and the live wire in the input line 12; the swing frame 43 includes two telescopic rods 431 arranged in parallel, the telescopic rod 431 includes a fixed rod 431a and a first movable rod 431b and a second movable rod 431c respectively arranged at both ends of the length, the fixed rod 431a is connected to the connecting shaft 42, the first movable rod 431b and the second movable rod 431c are respectively connected to the other telescopic rod 431 through the first electromagnetic coil 432 and the second electromagnetic coil 433 to form a conductive loop; the first movable rod 431b is connected to the communicating vessel 45, the first electromagnetic coil 432 is close to the middle position of the induction coil 454, and the two are axially arranged vertically, the first electromagnetic coil 432 and the second electromagnetic coil 433 are coaxially arranged and generate the same direction of magnetic field after power is turned on.

[0036] In the specific implementation process, the induction coil 454 is sleeved on the outer ring of the conductive wire 453 (including the live wire and the neutral wire) to detect the current in the live wire and the neutral wire. Under normal circumstances, the currents of the live wire and the neutral wire are equal in magnitude and opposite in direction, so no induced current is generated in the induction coil 454. When a fault occurs (such as a short circuit fault causing the neutral wire current to drop and the live wire current to remain unchanged), an induced current will be generated in the induction coil 454, and the magnetic field generated by the induced current will act on the first electromagnetic coil 432.

[0037] Furthermore, the first electromagnetic coil 432 is affected by the magnetic field generated by the induction coil 454, generating current that flows in the conductive loop; the first electromagnetic coil 432 and the second electromagnetic coil 433 are coaxially arranged, and generate magnetic fields in the same direction after being energized, attracting each other. The switching mechanism 4 completes the switching of different switchboards 3 through the driving force generated by the interaction of the two electromagnetic coils.

[0038] During the rotation of the swing frame 43, the mutual attraction between the first electromagnetic coil 432 and the second electromagnetic coil 433 drives the first movable rod 431b and the second movable rod 431c in the telescopic rod 431 to approach each other. The telescopic action of the telescopic rod 431 drives the swing frame 43 to rotate, and then drives the connecting tube 45 to move along the length direction of the support beam 44. The movement of the connecting tube 45 realizes the switching of the distribution board 3.

[0039] As a preferred embodiment of this embodiment, Figure 7 and Figure 8As shown, a first slide groove 431d is provided on the second movable rod 431c along its long direction, the second electromagnetic coil 433 is slidably connected to the first slide groove 431d through a slider 431e, and a leaf spring 431f is provided at one end of the first slide groove 431d close to the fixed rod 431a, and the leaf spring 431f drives the slider 431e away from the fixed rod 431a; a second slide groove 411 is provided on the fixed seat 41, and the second slide groove 411 is arranged parallel to the support beam 44, and the end of the second movable rod 431c is rotatably connected to the slider 412, and the slider 412 is slidably connected to the second slide groove 411.

[0040] Considering that in the specific implementation process, transient phenomena may occur due to the presence of inductance or capacitance, or due to the difference in line impedance. For example, if there is an inductive component (such as a motor or transformer) in the circuit, a transient high current spike may be generated at the moment of closing the switch, and the current distribution may be temporarily uneven during this process. However, this phenomenon is usually very short-lived and will not cause the current to flow only on the live wire but not on the neutral wire for a long time, so it does not belong to the fault of the switchboard 3.

[0041] The second electromagnetic coil 433 is slidably connected to the first slide groove 431d provided on the second movable rod 431c through the slider 431e. The first slide groove 431d structure provides a buffer space for the second electromagnetic coil 433 in the case of transient overcurrent, preventing it from erroneously switching due to the transient electromagnetic force. The elastic force of the leaf spring 431f can provide a stable restoring force for the second electromagnetic coil 433, which helps to restore it to a normal position after the transient phenomenon ends.

[0042] As a preferred embodiment of this embodiment, Fig. 9 and Fig.10 As shown, the middle parts of the first power connection plate 21 and the second power connection plate 22 are both hinged to the inner wall of the top of the box body 1, and the rotation axis thereof is perpendicular to the length direction of the support beam 44; the first limit seat 16 and the second limit seat 17 are respectively arranged on the inner wall of the top of the box body 1 corresponding to the first power connection plate 21 and the second power connection plate 22, and the first limit seat 16 and the second limit seat 17 are respectively located on the side of the hinge point of the first power connection plate 21 and the second power connection plate 22 away from the connecting shaft 42; an inclined surface 161 is arranged on the side of the first limit seat 16 and the second limit seat 17 facing the communicating vessel 45, and the inclined surface 161 is arranged away from the hinge point of the power connection plate.

[0043] Furthermore, metal springs 456 are provided at the top of the input end 451 and the output end 452, and the metal springs 456 include a first spring 456a and a second spring 456b respectively connected to the first wire and the second wire, and a first conductive row 211 and a second conductive row 212 are provided on the first power connection board 21 and the second power connection board 22 corresponding to the first spring 456a and the second spring 456b.

[0044] The middle part of the power board is hinged to the inner wall of the top of the box body 1, allowing the power board to rotate in the vertical plane, so as to facilitate docking with the connecting tube 45; the limit seat limits the rotation range of the power board, so that the power board can stably rotate and abut against the limit seat when the connecting tube 45 is pushed. The design of the inclined surface 161 on the limit seat enables the connecting tube 45 to be pressed and positioned when it moves into place, so as to achieve the locking effect of the power board and prevent the connecting tube 45 and the power board from accidentally falling off during operation.

[0045] The metal spring 456 has good elasticity and conductivity, and can ensure stable contact with the power board. The first power board 21 and the second power board 22 are provided with a first conductive row 211 and a second conductive row 212 corresponding to the first spring 456a and the second spring 456b. The conductive row and the metal spring 456 are provided correspondingly to ensure smooth transmission of current.

[0046] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
