Description

Technical Field

[0001] This invention relates to the field of power distribution technology, and more specifically to power metering boxes for power distribution. Background Technology

[0002] In power distribution systems, electricity metering boxes serve as the core carriers for electricity metering, line protection, and electricity consumption monitoring. They are widely used in various scenarios such as residential communities, industrial and commercial parks, urban village renovations, and temporary construction sites. Their structural design directly affects the stability, operation and maintenance efficiency, and cost control of the power distribution system. With the rapid development of the social economy, electricity load is showing a dynamic growth trend, the construction of smart grids is continuously advancing, and users' electricity needs are becoming more diversified and upgraded, placing higher demands on the adaptability and scalability of electricity metering boxes.

[0003] Currently, in response to scenarios such as changing electricity demand, power grid upgrades and renovations, and dynamic adjustments for multiple users, existing technologies generally adopt the solution of adding metering boxes. Specifically, in the scenario of phased commissioning of newly built residential communities, basic metering components are initially configured due to low occupancy rates. As occupancy rates increase and users demand capacity expansion, new metering boxes need to be added next to the existing metering boxes to accommodate newly added components such as current transformers, branch circuit breakers, and charging pile metering circuits. In the scenario of renovation of old communities and urban villages, the original metering boxes have limited space and cannot accommodate the component upgrade requirements of high-power electrical equipment. The only way to expand the installation space is to add metering boxes to realize the addition of overload protection components and anti-theft devices. During the smart grid upgrade process, traditional metering boxes need to add smart devices such as electricity information collectors, wireless communication modules, and remote control devices. Due to the limitations of the original box space, the functional upgrade is usually accomplished by adding smart metering boxes. However, the above-mentioned technical solution of adding a metering box has the following shortcomings: Firstly, installing a metering box requires additional purchase of the box body, matching wiring and fasteners. It also involves construction procedures such as digging new trenches for wiring, drilling holes in the wall, and connecting the circuit. This not only increases the equipment purchase cost and construction cost, but also leads to the idle waste of the original metering box. Secondly, in urban villages, old residential areas, and densely populated industrial and commercial parks where space is scarce, the installation of additional metering boxes faces the problem of insufficient space. In some cases, it is necessary to occupy public passages, weak areas of walls, or damage the original building structure, which not only affects the aesthetics of the environment but may also bring structural safety hazards.

Four sets of wire sleeves 806 are fixedly installed at the bottom of the mounting plate 801. In the above scheme: the rolling cooperation between conductor wheel one and conductor wheel two converts the sliding friction of the conductor into rolling friction, significantly reducing the conductor traction resistance, preventing conductor knots and wear, and improving wiring efficiency; the conductor sleeve provides initial guidance for the conductor, ensuring that the conductor accurately enters between the conductor wheel sets; the corresponding setting of conductor wheel one and conductor wheel two ensures the consistency of the conductor traction direction and prevents conductor deviation; the threaded adjustment rod can drive the mounting plate two to slide, adjusting the distance between conductor wheel one and conductor wheel two to adapt to conductors of different thicknesses and improve the versatility of the conductor assembly.

[0035] In this embodiment, the main housing 100 is equipped with an arrangement component 900. The arrangement component 900 includes an arrangement frame 901, a wire holder 902, and a distribution channel 903. The arrangement frame 901 is arranged in an array on the front side inside the main housing 100. Corresponding wire holders 902 are fixedly installed on the main housing 100 between the arrangement frames 901, and the wire holders 902 are provided with distribution channels 903 for splitting wires. In the above scheme: the layout rack provides a standardized installation benchmark for metering equipment, making the equipment arranged in a neat and orderly manner and improving the utilization rate of the internal space of the metering box; the diversion channels on the line base can classify and sort different lines, avoid the lines crossing and tangling, and facilitate subsequent line inspection, maintenance and expansion; the layout components can be extended and installed synchronously according to the space expansion of the expansion shell, adapting to the layout requirements after the metering box space is adjusted, and ensuring the standardization of equipment and line layout.

[0036] Working principle and usage process of this invention: S1. First, install the metering box; personnel cooperate with the parts and the mounting assembly 500 to connect and combine with the mounting port 503 on the main frame 501 to fix the main frame 501. Then, personnel hang the main box 100 on the hanger 505 through the mounting sleeve 504 on the back, and simultaneously realize the mounting combination of the main box 100. S2. When the main box 100 is being installed, the personnel will install the meter on the rack 901 inside the main box 100. The rack 901 has been pre-installed before the operation, and the wires introduced into the main box 100 can be diverted through the diversion channel 903 on the wire socket 902 to realize the daily operation of the main box 100. S3. When the wiring inside the main enclosure 100 needs to be adjusted, personnel can climb to the position of the main enclosure 100 to carry out wiring work. During wiring: The operator rotates the handle 711, using worm gear 717 and worm wheel 713 to drive the transmission shaft 712. Simultaneously, worm gear 715 on the transmission shaft 712, in conjunction with worm wheel 714, drives the main transmission shaft 701. Simultaneously, the main transmission shaft 701, through bevel gear set 704, drives the secondary transmission shaft 703. The secondary transmission shaft 703, acting as a transmission structure, synchronously drives the main transmission shaft 702, thus... The drive shaft 1 701 and drive shaft 2 702 rotate synchronously, so that the wire wheel 601 will rotate to realize the wire laying operation of the hoisting line 602. The hoisting line 602 passes through the wire channel 1 107 and the wire channel 2 108. At that time, the bottom trough 200 can be lowered and separated from the extension sleeve 300. The loop connector 203 separates from the loop interface 301 until the bottom trough 200 is lowered to the operating height of the ground personnel and stops. The required wires are inserted one by one into the bottom groove 200 of the box through the wire inlet 202. Then, the wires are categorized and inserted into the wire sleeve 806 for guidance. They are then led out through the corresponding wire pulleys 802 and 807. The wire sleeve 806 guides the wires, ensuring they are placed at their designated positions to prevent obstruction when personnel are pulling from heights. The clamping force between the wire pulleys 802 and 807 is adjusted in real-time via the threaded adjusting rod 804 to ensure... The clamping force between guide roller 1 802 and guide roller 2 807 meets the guiding requirements; after the wire end is pulled out from between guide roller 1 802 and guide roller 2 807, the operator can rotate the handle 711 again and lift the bottom groove 200 of the box according to the above steps until the bottom groove 200 of the box and the expansion sleeve 300 are connected and combined again. In this way, the operator can pull out as much as needed according to the actual wiring requirements, while the wire roll is placed on the ground, eliminating the need for frequent manual feeding. S4. When the internal space of the main enclosure 100 is insufficient, it is necessary to expand the internal space of the main enclosure 100. The expansion method is as follows: The operator will pull the positioning knob 414 to disengage it from the positioning hole 105, releasing the lock on the toggle block 413. The block 412 will then be lowered, and the connecting sleeve 411 will mate with the snap connector 707 on the top of the transmission column 706, enabling the transmission column 706 to mate with the threaded drive rod 415 through the connecting sleeve 411 and enter the linkage state. Then, the fastening rotation 109 will be disassembled, causing the positioning state between the expansion sleeve 300 and the main housing 100 to be released. According to the above process: the operator rotates the rotating handle 711, using the worm gear 717 and worm wheel 713 to drive the transmission shaft 712. At that time, the worm gear 715 on the transmission shaft 712 can cooperate with the worm wheel 714 to drive the transmission main shaft 701 to rotate. Simultaneously, the transmission main shaft 701 drives the transmission secondary shaft 703 through the bevel gear set 704. The transmission secondary shaft 703, as a transmission structure, drives the transmission main shaft 702 synchronously, causing the transmission main shaft 701 and the transmission main shaft 702 to rotate synchronously. In this way, the wire wheel 601 will rotate to realize the wire laying operation of the hoisting line 602. At that time, the bottom trough 200 can be separated from the expansion sleeve 300 when the hoisting line 602 is lowered, and the loop connector 203 separates from the loop interface 301. Since the expansion sleeve 300 and the main housing 100 have been released from positioning, when the bottom groove 200 of the housing is lowered, the expansion sleeve 300 will be lowered synchronously. The height of the descent must match the spacing of the adjustment holes 302. At that time, the downward length of the expansion sleeve 300 will be extended and expanded. When the adjustment hole 302 on the expansion sleeve 300 is adjusted to a certain position, the operator can rotate and tighten the rotating 109 again to connect the adjustment hole 302 and lock the main housing 100. In this way, the expansion sleeve 300 will meet the required expansion requirements. Then, the arrangement frame 901 is assembled and connected to the assembly hole 303 in the expansion sleeve 300 to meet the required meter assembly requirements. When the transmission main shaft 701 rotates, the bevel gear set 705 synchronously drives the transmission column 706 to rotate. The transmission column 706 rotates through the snap-fit ​​connector 707 and the connecting sleeve 411. The inner bushing of the connecting sleeve 411 acts as an intermediary to drive the threaded drive rod 415 to rotate. The threaded drive rod 415 uses its own threads to drive the venting housing 400. The venting housing 400 is driven by the threads and limited by the upper interlayer cavity 101 to move up or down. When the bottom groove 200 extends downward, the venting housing 400 will be lifted upward. This satisfies the requirement to simultaneously expand the volume of the heat dissipation holes due to the expansion of the internal arrangement space. In this way, the metering box can adapt to the required heat dissipation and air guiding needs according to its internal assembly volume.
