Description

Technical Field

[0001] This invention relates to the field of electricity metering box technology, and more specifically, to an electricity metering box with flexible wiring. Background Technology

[0002] An electricity metering box is a key device specifically used in power systems for accurate electricity metering and data recording. It can measure, count, and store users' electricity consumption in real time and accurately. It is an indispensable and important component in the process of power supply and electricity management. This device is widely used in various industrial, commercial, and civil buildings, providing a reliable data foundation for electricity billing, electricity monitoring, and energy management. The present invention relates to an electricity metering box with flexible wiring function. Its structural design is optimized, the wiring is more reasonable, it can adapt to different on-site installation conditions, and improve construction and maintenance efficiency.

[0003] According to patent document CN116316090A, a modular energy metering box is disclosed, comprising a main component including a meter box, a metering component, and a connector. The metering component is disposed inside the meter box, and the connector is located on one side of the meter box. A wiring assembly is also disclosed on one side of the meter box, including a support component, a positioning component, a wiring component, a clamping component, and fasteners. The support component is located on one side of the meter box, the positioning component is located inside the support component, and the wiring component is disposed on the positioning component. The beneficial effects of this invention are: by setting the position of the movable fixing frame with the positioning component, the spacing between the fixing frames can be flexibly adjusted, thereby providing sufficient space for the installation and commissioning of the circuit breaker. Simultaneously, the support plate and clamping plate can reinforce and fix the wiring on one side of the circuit breaker, facilitating wiring by workers and preventing the wiring from accidentally falling off the circuit breaker.

[0004] During the installation of electricity metering boxes, it is usually necessary to run the wiring of the meters inside the box. During the wiring process, due to the different installation space required for circuit breakers of different specifications, the internal layout of traditional metering boxes is difficult to adjust flexibly, which may restrict the wiring operation and pose a risk of wires coming loose. When long wires are introduced into the metering box for wiring, some of the wires may hang down inside the box due to their length, which may cause the wires to become tangled and cause safety hazards. In addition, when the staff inspects the wiring, the complexity of the wiring may increase the difficulty of inspection and time costs, thereby affecting the overall work efficiency.

Motor connecting blocks 2412 are fixedly connected to the top of both guide plates 2411. Motors 24111 are fixedly connected to the inner walls of both motor connecting blocks 2412. The output ends of both motors 24111 extend to the bottom of both motor connecting blocks 2412 and are fixedly connected to lead screws 2413. Bottom blocks 2415 are fixedly connected to the bottom of the front side of both guide plates 2411. Upright rods 2416 are fixedly connected to the top of both bottom blocks 2415. Transmission blocks 2414 are threadedly connected to the outer walls of both lead screws 2413. The outer walls of 414 are slidably connected to the inner walls of the two guide plates 2411. Slider blocks 2417 are fixedly connected to the front sides of the two transmission blocks 2414. Retraction rods 2418 are rotatably connected to the tops of the left and right sides of the two uprights 2416. Second retraction rods 2419 are rotatably connected to the left and right sides of the two sliders 2417. Convex push-pull blocks 24110 are rotatably connected to the tops of the inner front sides of the left and right retraction rods 2418. Convex push-pull blocks 24110, identical to those on the inner sides of the two sets of second retraction rods 2419, are rotatably connected to the bottoms of the inner front sides of the two sets of retraction rods 2418. The outer sides of the left and right retraction rods 2418 are rotatably connected to the inner sides of the two sets of second retraction rods 2419. The two guide members 242 are connected in a dynamic manner. Each guide member 242 includes a guide plate support plate 2421. The inner sides of the two guide plate support plates 2421 are fixedly connected to the bottom of the outer side of the two guide upright plates 2411. The top of the two guide plate support plates 2421 is fixedly connected to an L-shaped longitudinal guide plate 2422. The bottom of the two L-shaped longitudinal guide plates 2422 is fixedly connected to a longitudinal guide plate bottom connecting plate 2423. The front side of the bottom of the two longitudinal guide plate bottom connecting plates 2423 is fixedly connected to a bottom connecting block 2424. The front side of the inner side of the two L-shaped longitudinal guide plates 2422 is fixedly connected to an upright L-shaped connecting plate 2425. The top of the rear side of the two upright L-shaped connecting plates 2425 is fixedly connected to a rack rod 2426. When wiring is required for the electricity metering box 1, the wires are wound around the wire take-up and release assembly 25. The take-up and release of the wires are controlled by the wire take-up and release assembly 25. The wires fall into the metering box body 11 through the two elongated wire routing slots 12. When it is necessary to route the wires to the front of the electricity metering box 1, the motor 24111 on the side where the wires need to be routed is started. After the motor 24111 starts, it drives the lead screw 2413 to start rotating. Since the transmission block 2414 is threadedly connected to the lead screw 2413, and the transmission... Block 2414 can only move linearly due to the restriction of the inner wall of guide plate 2411. Therefore, transmission block 2414 will move along the axial direction of lead screw 2413. When transmission block 2414 moves, it will drive slider 2417 to move synchronously. The movement of slider 2417 will cause the second retractable assembly rod 2419 to rotate, thereby pushing the convex push-pull block 24110 to move. The movement of convex push-pull block 24110 will drive the retractable assembly rod 2418 to perform unfolding or retracting actions, thereby changing the position of the line retractable assembly 25. Meanwhile, the L-shaped longitudinal guide plate 2422 in the guide component 242 will provide guidance and support for the movement of the line. Under the drive of the control component 241, the line winding and unwinding component 25 will wind the line from the rear to the front of the power metering box 1 according to the preset trajectory, or wind the line in the opposite direction as needed. Once the cable is laid to the designated position, the motor 24111 is turned off, the lead screw 2413 stops rotating, and the transmission block 2414, slider 2417, and retractable rod 2418 and second retractable rod 2419 all stop moving. The cable retractable assembly 25 is also fixed in the current position, completing the cable laying operation. The entire cable laying process is flexible and efficient, and can meet the cable laying needs of the power metering box 1 in different scenarios.

[0022] like Figure 10As shown, both cable retraction assemblies 25 include a base plate 251. The bottom of both base plates 251 is slidably connected to the top of two L-shaped longitudinal guide plates 2422. Push-pull upright plates 252 are fixedly connected to the front inner side of both base plates 251. The rear side of both push-pull upright plates 252 is fixedly connected to the front side of two sets of left and right convex push-pull blocks 24110. Rectangular upright plates 253 are fixedly connected to the middle of the top of both base plates 251. Circular grooves 258 are formed in the middle of the middle of both rectangular upright plates 253. The bottom of both circular grooves 258 is hollowed out. Columnar rotating rods 254 are rotatably connected to the middle of the top of both rectangular upright plates 253. The outer walls of the two columnar rotating rods 254 are on the outside of the two rectangular upright plates 253. One side of each of the two cylindrical rotating rods 254 is fixedly connected to a winding roller 255. The inner ends of the two cylindrical rotating rods 254 extend to the inner sides of the two rectangular vertical plates 253. The inner ends of the two cylindrical rotating rods 254 are fixedly connected to gears 256. The outer walls of the two gears 256 mesh with the tops of the two rack rods 2426. The two rectangular vertical plates 253 have through holes 257 on one side of the top of the two winding rollers 255. The front and rear sides of the bottom of the outer side of the two rectangular vertical plates 253 are fixedly connected to triangular side support plates 259. The bottoms of the two sets of triangular side support plates 259 are fixedly connected to the front and rear sides of the top of the two bottom support plates 251. The left and right sides of the front and rear sides of the top center of the bottom support plate 251 are fixedly connected to rotating rod side connecting blocks 2514. Multiple sets of rotating rods The inner side of each side connecting block 2514 is rotatably connected to a columnar transmission rod 2515. The rear ends of the two outermost columnar transmission rods 2515 are fixedly connected to a transmission disc 2516. The front and rear sides of the bottom outer sides of the two rectangular vertical plates 253 are fixedly connected to guide block connecting rods 2510. The inner sides of the left and right sets of guide block connecting rods 2510 are fixedly connected to guide blocks 2511. The inner sides of the left and right sets of guide blocks 2511 are rotatably connected to guide wheels 2512. The bottom of the two guide wheels 2512 is in contact with the top of the outer wall of the left and right sets of columnar transmission rods 2515. The middle of the outer wall of the two guide wheels 2512 is fixedly connected to a concave guide disc 2513. The middle of the outer sides of the two bottom support plates 251 are fixedly connected to a rectangular connecting rod 2516. The connecting block 2517 has two rectangular connecting blocks 2517, both front and rear sides of which are fixedly connected to wire feeding rotating rod connecting side blocks 2518. The inner walls of both sets of wire feeding rotating rod connecting side blocks 2518 are slidably connected to positioning sliders 25110. Springs 25111 are fixedly connected to both sides of the bottom of both sets of positioning sliders 25110. Wire feeding bottom rollers 25112 are rotatably connected to the inner sides of both sets of positioning sliders 25110. Second motor connecting blocks 2519 are fixedly connected to the inner sides of the two front wire feeding rotating rod connecting side blocks 2518. Second motors 25117 are fixedly connected to the tops of the two second motor connecting blocks 2519. Wire feeding roller cylindrical rotating rods 25113 are fixedly connected to the output ends of the two second motors 25117.Both front and rear sides of the outer walls of the two wire-feeding roller cylindrical rotating rods 25113 are rotatably connected to the top inner walls of the two sets of wire-feeding rotating rod connecting side blocks 2518. A wire-feeding top roller 25116 is fixedly connected to one side of the outer walls of the two wire-feeding roller cylindrical rotating rods 25113 inside the two sets of wire-feeding rotating rod connecting side blocks 2518. A second transmission disc 25114 is fixedly connected to the rear end of each of the two wire-feeding roller cylindrical rotating rods 25113. Tracks 25115 are fitted onto the outer walls of the two second transmission discs 25114. The inner walls of the two tracks 25115, away from the second transmission discs 25114, are fitted onto the outer walls of the two transmission discs 2516. The wire passes through the through hole 257 of the rectangular vertical plate 253 to the outside of the rectangular vertical plate 253 and is wound around the outer wall of the winding roller 255. One end of the wire passes through the concave wire disc 2513 in the middle of the wire guide wheel 2512 to the inner side of the wire feeding top roller 25116 and the wire feeding bottom roller 25112. When the entire wire take-up and unwinding assembly 25 is moved under the control of the telescopic control frame 24, the gear 256 at the rear end of the columnar rotating rod 254 will mesh and move along the top of the rack 2426. Since the gear 256 is fixedly connected to the columnar rotating rod 254, the columnar rotating rod 254 will rotate accordingly, thereby driving the winding roller 255 to rotate, realizing the wire take-up and unwinding action. Meanwhile, the guide wheel 2512 also rotates under the drive of the columnar transmission rod 2515, and guides the line in conjunction with the concave guide disc 2513 to ensure that the line will not be tangled or knotted during the winding and unwinding process. When the line needs to be sent out, the second motor 25117 on the second motor connecting block 2519 is started. The columnar transmission rod 25113 drives the top roller 25116 and the second transmission disc 25114 to rotate. Then, the power is transmitted to the transmission disc 2516 through the track 25115, which in turn drives the columnar transmission rod 2515 and the guide wheel 2512 to rotate, sending the line out between the bottom roller 25112 and the top roller 25116. The entire line winding and unwinding assembly 25 is ingeniously designed, and the components work together to achieve flexible winding and unwinding and precise guidance of the line, which greatly facilitates the wiring work of the power metering box 1. This method ensures that the line is extended and retracted to the appropriate length at the correct location, preventing situations where the line is suspended in the middle or excessively redundant. This effectively avoids safety hazards caused by improper line length, such as short circuits and leakage. At the same time, this design greatly improves the utilization rate of the internal space of the electricity metering box, making the internal layout of the box more compact and reasonable, which facilitates subsequent maintenance and repair work. In addition, the modular design of the line extension and retraction components makes its installation and replacement simpler and faster, reducing operation and maintenance costs and improving work efficiency.

[0023] Working principle of the invention: When wiring is required for the electricity metering box 1, the wires are wound around the wire take-up and release assembly 25. The take-up and release of the wires are controlled by the wire take-up and release assembly 25. The wires fall into the metering box body 11 through the two elongated wire routing slots 12. When the wires need to be routed to the front of the electricity metering box 1, the motor 24111 on the side requiring wiring is started. After the motor 24111 starts, it drives the lead screw 2413 to start rotating. Since the transmission block 2414 is threadedly connected to the lead screw 2413, and the transmission block 2414 can only move linearly due to the restriction of the inner wall of the guide plate 2411, the transmission block 2414 will move along the axial direction of the lead screw 2413. When moving, the slider 2417 moves synchronously, and the movement of the slider 2417 causes the second retractable rod 2419 to rotate, which in turn pushes the convex push-pull block 24110 to move. The movement of the convex push-pull block 24110 causes the retractable rod 2418 to unfold or retract, thereby changing the position of the line retractable assembly 25. At the same time, the L-shaped longitudinal guide plate 2422 in the guide member 242 provides guidance and support for the movement of the line. Under the drive of the control component 241, the line retractable assembly 25 will arrange the line from the rear side to the front side of the power metering box 1 according to the preset trajectory. The line passes through the through hole 257 opened in the rectangular vertical plate 253 to the outside of the rectangular vertical plate 253 and is wound around the outer wall of the winding roller 255. One end passes through the concave guide disc 2513 in the middle of the guide wheel 2512 to the inner side of the top feed roller 25116 and the bottom feed roller 25112. When the entire cable take-up and unwinding assembly 25 is moved under the control of the telescopic control frame 24, the gear 256 at the rear end of the columnar rotating rod 254 will mesh and move along the top of the rack rod 2426. Since the gear 256 is fixedly connected to the columnar rotating rod 254, the columnar rotating rod 254 will rotate accordingly, thereby driving the winding roller 255 to rotate, realizing the cable take-up and unwinding action. At the same time, the guide wheel 2512 will also rotate under the drive of the columnar transmission rod 2515, cooperating with the concave guide disc 2513 to guide the cable, ensuring that the cable will not tangle or knot during the take-up and unwinding process. When the cable needs to be... When the wire is to be delivered, the second motor 25117 on the second motor connecting block 2519 is started. The wire delivery roller 25116 and the second transmission disc 25114 are rotated through the wire delivery roller cylindrical rotating rod 25113.
