Description

Technical Field

[0001] This invention relates to the field of electricity meter replacement technology, and more specifically, to a wiring device with electricity meter power supply function. Background Technology

[0002] The primary function of electricity meters is to measure electricity. They exist in all stages of the power grid—generation, transmission, distribution, and consumption—and are an important component of the power system. They accurately measure power generation, grid-connected electricity, power supply, and electricity sales, and provide data support for technical and economic indicators such as network loss and line loss. Due to damage caused by prolonged use or the need for meter replacement, meters need to be replaced to ensure proper operation. When replacing meters, the current return circuit connected to the meter box cannot be opened, so power must be disconnected for the work. During the power outage, users cannot receive normal power, causing great inconvenience. Large-scale replacements, sometimes involving thousands of meters, result in significant power outages in terms of scope, duration, and frequency.

[0003] Patent No. CN208432649U discloses a three-phase energy meter replacement device that does not require power outages. The device includes a wiring port adapter, a multi-functional integrated wiring device, and a shorting connector. The shorting connector is inserted into the multi-functional integrated wiring device, and one end of the wiring port adapter is inserted into the three-phase energy meter. The other end of the adapter is then connected to the multi-functional integrated wiring device. Finally, the shorting connector is removed, and the three-phase energy meter can be replaced without power outages.

[0004] When the above solution is used, the uninterruptible replacement device converts the unplugged, non-energized socket of the meter into a non-energized plug, so that the multi-functional integrated connector only has energized sockets, which greatly improves the safety of operation and provides a safe uninterrupted short-circuit structure for meter replacement. However, during use, before replacement, the short-circuit devices need to be inserted into the multi-functional integrated connector one by one, and they also need to be removed one by one. There are many parts, and disassembly and assembly are not convenient, which reduces the work efficiency of the installers. In addition, during the replacement of the electricity meter, the user may still be using electricity, and the user's electricity consumption cannot be measured, which affects the accuracy of the electricity meter measurement. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a wiring device with a power meter regeneration function, enabling uninterrupted replacement of the electricity meter body. This is convenient, quick, and reduces the replacement cycle of the electricity meter, allowing grid users to continue using electricity during the meter replacement process. By rotating the new electricity meter body and its bottom insulating plate, and pushing the new electricity meter body to the side, the arc head and the insulating plate are engaged with the inside of the conductive sheet, achieving uninterrupted metering. This makes the electricity meter measurement more accurate and the replacement more convenient and faster, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wiring device with a power meter continuing function, comprising a power meter body, a protective cover plate detachably installed at one end of the power meter body, a connecting component embedded in the bottom of the power meter body, a wiring component embedded in the other side of the connecting component, a wiring cover detachably installed on the top of the wiring component, and multiple connecting lines snapped onto the side of the wiring component away from the connecting component; the wiring component includes a base plate, a wire fixing component fixedly connected to one end of the top of the base plate, and a switching device fixedly connected to the other end of the top of the base plate on the side of the wire fixing component, the side of the wire fixing component away from the switching device snapped onto the connecting lines, and the switching device embedded in one end of the connecting component; the wiring cover includes a protective cover, connecting plates fixedly connected to both sides of the protective cover, a limit hole provided on one side of the protective cover, the connecting plates detachably installed to the base plate by bolts, the limit hole movably sleeved on the outer surface of the connecting lines, and the protective cover sleeved on the outer surface of the wire fixing component and the switching device.

An arc-shaped head is fixedly connected to the end of the conductive rod away from the insulating plate, and the diameter of the arc-shaped head is larger than the diameter of the conductive rod. The conductive rods at both ends of the insulating plate are respectively snapped onto one end of the energy meter body and one end of the wiring assembly.

[0008] In a preferred embodiment, the wire fixing assembly includes a first wire fixing frame, the top of which is provided with a plurality of first wire fixing bolts. The first wire fixing frame is movably sleeved on one end of the connecting line and fixedly installed by the first wire fixing bolts. A movable cavity is opened at the top of the end of the first wire fixing frame away from the connecting line. A compression spring is fixedly connected inside the movable cavity. A pressing block is fixedly connected to the bottom of the compression spring. The pressing block is movably sleeved inside the movable cavity. A shorting piece is fixedly connected to the bottom of the pressing block. The shorting piece is made of conductive metal and its two ends correspond to two corresponding connecting lines. One side of the pressing block is a slope.

[0009] In a preferred embodiment, the switching device includes a first socket bracket, the interior of which has a snap-fit ​​hole corresponding to the connecting line, and a fastening bolt corresponding to the first wire fixing bolt is provided on the top of the first socket bracket above the snap-fit ​​hole. A moving groove is provided on the upper end of the first socket bracket near the wire fixing assembly, and a push spring is fixedly connected to the inner wall of the moving groove. A push block is fixedly connected to the other end of the push spring, and the push block is slidably installed inside the moving groove. The side of the push block is an inclined surface corresponding to the pressing block. The snap-fit ​​hole is snapped onto the outer surface of the conductive rod and fixed by the fastening bolt.

[0010] In a preferred embodiment, the first socket is fixedly installed on the side of the first cable holder, and a sliding groove is provided on the top of the first socket near the top of the first cable holder. A push rod is fixedly connected to the top of the push block, and the push rod is slidably installed inside the sliding groove. Limiting components are fixedly connected to both ends of the top of the first socket on both sides of the sliding groove.

[0011] In a preferred embodiment, the limiting component includes a fixed block, the fixed block having a movable groove inside, a movable rod being movably sleeved inside the movable groove, a ball being rotatably mounted at one end of the movable rod, a snap-fit ​​spring being movably sleeved on the outer surface of the movable rod between the movable groove and the ball, and one side of the ball being snap-fitted onto the side of the push rod.

[0012] In a preferred embodiment, the cable fixing assembly includes a second cable fixing bracket fixedly installed at one end of the top of the base plate. The top of the second cable fixing bracket is provided with a plurality of second cable fixing bolts. The second cable fixing bracket is movably sleeved on one end of the connecting line and fixedly installed by the second cable fixing bolts.

[0013] In a preferred embodiment, the switching device includes a second socket frame, one end of the top of the second socket frame is provided with a rotating groove corresponding to the connecting line, the second socket frame is fixedly installed on the side of the second wire fixing frame, and a conductive sheet is fixedly connected to one end of the second socket frame located in the rotating groove, one end of the conductive sheet is embedded in one end of the connecting line.

[0014] In a preferred embodiment, the conductive sheet has a notch at its top and a groove at one end of the notch in the middle of the top of the conductive sheet. The conductive sheet is made of an elastic conductive metal. The bottom of the rotating groove is lower than the bottom of the conductive sheet. The side of the groove closest to the connecting line is sloped. A return spring is fixedly connected to the bottom of the end of the conductive sheet away from the connecting line. The bottom of the return spring is fixedly installed on the surface of the rotating groove. The conductive sheet is snapped onto the outer surface of the arc head.

[0015] The technical effects and advantages of this invention are as follows: This invention involves pushing a push rod away from the first wire-fixing frame, causing the push rod to move a push block into the moving slot, short-circuiting the connecting lines inside the first wire-fixing frame. This allows the old electricity meter to be pulled out from the side of the first mounting bracket, and the conductive rod in the connecting assembly at the bottom of the new electricity meter to be inserted into the locking hole, bringing the connecting assembly into contact with the connecting lines. The connecting assembly is then secured by the fastening bolt at the top of the locking hole. Pushing the push rod towards the side of the first wire-fixing frame disengages the short-circuit from the connecting lines, and the push rod engages with one end of the limiting assembly. This allows for electricity meter replacement without power interruption, making it convenient, quick, and reducing the meter replacement cycle, ensuring that grid users can continue to use electricity during meter replacement.

[0016] This invention involves removing the protective cover from the surface of the base plate. When the insulating plate at the bottom of the new energy meter body descends and presses into the groove, the conductive sheet undergoes elastic deformation, causing it to detach from the old insulating plate. By rotating the new energy meter body and its bottom insulating plate, and pushing the new energy meter body to the side, the arc head and the insulating plate are engaged with the inside of the conductive sheet. This allows for uninterrupted metering while maintaining power, making the energy meter readings more accurate and the replacement process more convenient and faster.

[0017] By setting up a connection component, this invention can adapt to different types of existing electricity meters, thus increasing the applicability of the device. At the same time, it eliminates the need for wiring, effectively protecting the personal safety of workers and improving their work efficiency. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1 As attached Figure 1-5The wiring device shown includes an electricity meter body 1, a protective cover 2 detachably installed at one end of the electricity meter body 1, a connecting component 6 embedded in the bottom of the electricity meter body 1, a wiring component 5 embedded in the other side of the connecting component 6, a wiring cover 3 detachably installed on the top of the wiring component 5, and multiple connecting wires 4 snapped onto the side of the wiring component 5 away from the connecting component 6; the wiring component 5 includes a base plate 51, a wire fixing component 52 fixedly connected to one end of the top of the base plate 51, and the other end of the top of the base plate 51 located in the wire fixing component. A switching device 53 is fixedly connected to the side of component 52. The side of the wire fixing assembly 52 away from the switching device 53 is snapped into the connecting line 4. The switching device 53 is embedded in one end of the connecting assembly 6. The wiring cover 3 includes a protective cover 31. A connecting plate 33 is fixedly connected to both sides of the protective cover 31. A limit hole 32 is opened on one side of the protective cover 31. The connecting plate 33 is detachably installed to the base plate 51 by bolts. The limit hole 32 is movably sleeved on the outer surface of the connecting line 4. The protective cover 31 is sleeved on the outer surface of the wire fixing assembly 52 and the switching device 53.

[0029] As attached Figure 5 As shown, the connecting assembly 6 includes an insulating plate 61, with conductive rods 62 fixedly connected to both ends of the insulating plate 61. An arc head 63 is fixedly connected to the end of the conductive rod 62 away from the insulating plate 61. The diameter of the arc head 63 is larger than the diameter of the conductive rod 62. The conductive rods 62 at both ends of the insulating plate 61 are respectively snapped onto one end of the energy meter body 1 and one end of the wiring assembly 5.

[0030] Since the diameter of the arc head 63 is larger than the diameter of the conductive rod 62, when the conductive rod 62 is fastened to the surface of the conductive rod 62 by bolts, the arc head 63 prevents the conductive rod 62 from falling off the bolts, thereby improving the stability of the connection between the connecting assembly 6 and the energy meter body 1 and the wiring assembly 5.

[0031] As attached Figure 3 As shown, the wire fixing assembly 52 includes a first wire fixing frame 521. The top of the first wire fixing frame 521 is provided with a plurality of first wire fixing bolts 522. The first wire fixing frame 521 is movably sleeved on one end of the connecting line 4 and fixedly installed by the first wire fixing bolts 522. The top of the end of the first wire fixing frame 521 away from the connecting line 4 has a movable cavity 523. A compression spring 526 is fixedly connected inside the movable cavity 523. A pressing block 524 is fixedly connected to the bottom of the compression spring 526. The pressing block 524 is movably sleeved inside the movable cavity 523. A shorting piece 525 is fixedly connected to the bottom of the pressing block 524. The shorting piece 525 is a conductive metal and its two ends are respectively corresponding to two connecting lines 4. One side of the pressing block 524 is a slope.

[0032] By using the shorting piece 525, the corresponding connecting line 4 is short-circuited, thereby ensuring uninterrupted power supply when replacing the electricity meter. In addition, since the pressing block 524 and the pushing block 534 have corresponding inclined surfaces on both sides, when the pushing block 534 moves to the side of the pressing block 524, the inclined surface of the pushing block 534 will push the pressing block 524 upward, causing the compression spring 526 to compress. The shorting piece 525 will then disengage from the top of the connecting line 4, thus disengaging the shorting piece 525 from the connecting line 4. Similarly, when the pushing block 534 moves out of the bottom of the pressing block 524, the shorting piece 525 will descend to the surface of the connecting line 4 due to the reset action of the compression spring 526, thus short-circuiting the corresponding connecting line 4.

[0033] The switching device 53 includes a first connecting frame 531. The first connecting frame 531 has a snap-fit ​​hole 532 corresponding to the connecting line 4 inside. The top of the first connecting frame 531, above the snap-fit ​​hole 532, is provided with a fastening bolt corresponding to the first fixing bolt 522. The upper end of the first connecting frame 531 near the fixing assembly 52 has a moving groove 537. The inner wall of the moving groove 537 is fixedly connected to a push spring 533. The other end of the push spring 533 is fixedly connected to a push block 534. The push block 534 is slidably installed inside the moving groove 537. The side of the push block 534 is an inclined surface corresponding to the pressing block 524. The snap-fit ​​hole 532 is snapped onto the outer surface of the conductive rod 62 and fixed by the fastening bolt.

[0034] The first socket 531 is fixedly installed on the side of the first wire fixing frame 521. The first socket 531 has a sliding groove 535 near the top of the first wire fixing frame 521. The top of the push block 534 is fixedly connected to the push rod 536, which is slidably installed inside the sliding groove 535. The two ends of the top of the first socket 531 are fixedly connected to the limit components 54 on both sides of the sliding groove 535.

[0035] As attached Figure 4 As shown, the limiting component 54 includes a fixed block 541, the fixed block 541 has a movable groove 542 inside, a movable rod 543 is movably sleeved inside the movable groove 542, a ball bearing 545 is rotatably mounted on one end of the movable rod 543, a snap-fit ​​spring 544 is movably sleeved on the outer surface of the movable rod 543 between the movable groove 542 and the ball bearing 545, and one side of the ball bearing 545 is snap-fitted onto the side of the push rod 536.

[0036] By using the ball bearing 545, when the push rod 536 moves to one end of the ball bearing 545, the support of the snap-fit ​​spring 544 prevents the push rod 536 from sliding to the side when it is squeezed by the compression spring 526 in the sliding groove 535, thereby achieving the separation between the shorting piece 525 and the connecting line 4.

[0037] Example 2 Considering that users continue to consume electricity during the meter replacement process, and that this consumption cannot be accurately recorded, the following measures are provided to overcome this issue: Figure 6-8 As shown, the cable fixing assembly 52 includes a second cable fixing frame 501 fixedly installed at one end of the top of the base plate 51. The top of the second cable fixing frame 501 is provided with a plurality of second cable fixing bolts 502. The second cable fixing frame 501 is movably sleeved on one end of the connecting line 4 and fixedly installed by the second cable fixing bolts 502.

[0038] As attached Figure 7 As shown, the switching device 53 includes a second socket 051. One end of the top of the second socket 051 is provided with a rotating groove 054 corresponding to the connecting line 4. The second socket 051 is fixedly installed on the side of the second wire frame 501. A conductive sheet 052 is fixedly connected to one end of the second socket 051 located in the rotating groove 054. One end of the conductive sheet 052 is embedded in one end of the connecting line 4.

[0039] As attached Figure 8 As shown, the top of the conductive sheet 052 is provided with a notch 053, and the middle of the top of the conductive sheet 052 is provided with a groove 055 at one end of the notch 053. The conductive sheet 052 is made of elastic conductive metal. The bottom of the rotating groove 054 is lower than the bottom of the conductive sheet 052. The side of the groove 055 near the connecting line 4 is inclined. A return spring 056 is fixedly connected to the bottom of the end of the conductive sheet 052 away from the connecting line 4. The bottom of the return spring 056 is fixedly installed on the surface of the rotating groove 054. The conductive sheet 052 is snapped onto the outer surface of the arc head 63.

[0040] The conductive sheet 052 is made of elastic material. When the new insulating plate 61 descends and presses into the interior of the groove 055, the conductive sheet 052 undergoes elastic deformation. Utilizing the inclined surface at one end of the groove 055, the insulating plate 61 is brought closer to one end of the return spring 056, causing one end of the conductive sheet 052 to descend under pressure. At this time, the conductive sheet 052 descends and detaches from one end of the old insulating plate 61, thus separating the conductive sheet 052 from the old insulating plate 61. At this point, the conductive sheet 052 is directly electrically connected to the insulating plate 61. Furthermore, during the descent and separation of the conductive sheet 052 from the old insulating plate 61, the notch 053 unfolds, allowing the arc head 63 to engage with the interior of the groove 055. At this time, the diameter of the arc head 63 is larger than the diameter of the insulating plate 61. By rotating the insulating plate 61 and pushing the energy meter body 1 to the side, the arc head 63 and the insulating plate 61 are engaged with the interior of the conductive sheet 052, achieving the function of metering while maintaining power.

[0041] Working principle of the invention: When replacing, the protective cover 2 is removed from the power meter body 1, the conductive rod 62 on one side of the connecting component 6 is snapped into the power meter body 1, and then fixed by the bolts on the power meter body 1. The connecting lines 4 are fixed inside the first wire fixing frame 521 by the first wire fixing bolts 522 respectively. When replacing the old electricity meter body 1, loosen the fastening bolts on the surface of the first mounting bracket 531 located at the top of the snap-fit ​​hole 532. Push the push rod 536 away from the first mounting bracket 521, causing the push rod 536 to move the push block 534 into the moving groove 537. The spring 526 is then reset, causing the pressing block 524 to move the shorting piece 525 downwards, shorting the connecting line 4 inside the first mounting bracket 521. The old electricity meter body 1 is then pulled out from the side of the first mounting bracket 531. After installing the connecting assembly 6 on the side of the new electricity meter body 1, insert the conductive rod 62 from the connecting assembly 6 at the bottom of the new electricity meter body 1 into the snap-fit ​​hole 532, so that the connecting assembly 6 connects with the connecting wire. The circuit 4 is brought into contact, and the connecting assembly 6 is fastened by the fastening bolt at the top of the snap-fit ​​hole 532. The push rod 536 is pushed to the side of the first wire fixing frame 521, so that the push rod 536 moves to the bottom of the pressing block 524. Since the pressing block 524 and the push snap-fit ​​block 534 have corresponding inclined surfaces on both sides, when the push snap-fit ​​block 534 moves to the side of the pressing block 524, the pressing block 524 will be pushed up under the action of the inclined surface of the push snap-fit ​​block 534, so that the compression spring 526 is compressed, the shorting piece 525 is disengaged from the top of the connecting circuit 4, so that the shorting piece 525 is disengaged from the connecting circuit 4, and the push rod 536 is snapped into one end of the limiting assembly 54, so that the power meter body 1 can be replaced without interrupting the power supply. Considering that users are still using electricity during the meter replacement process, the electricity consumption at this time cannot be counted. To overcome this problem, the connecting component 6 can be installed inside the new meter body 1. Then, the protective cover 31 can be removed from the surface of the base plate 51. At this time, when the insulating plate 61 at the bottom of the new meter body 1 descends and presses into the groove 055, the conductive piece 052 will undergo elastic deformation. Using the inclined surface at one end of the groove 055, the insulating plate 61 is brought close to one end of the return spring 056, and one end of the conductive piece 052 is lowered by force. At this time, the conductive piece 052 descends and separates from one end of the insulating plate 61 at the bottom of the old meter body 1, realizing the separation of the conductive piece 052 from the old insulating plate 61, and the old meter body 1 can be pulled out. At the bottom of the meter body 1, the connecting component 6 connects the conductive sheet 052 directly to the insulating plate 61 and measures the connection line 4. In addition, during the process of the conductive sheet 052 descending and separating from the insulating plate 61 at the bottom of the old meter body 1, the notch 053 will unfold, so that the arc head 63 can be engaged with the inside of the groove 055. At this time, the diameter of the arc head 63 is larger than the diameter of the insulating plate 61. By rotating the new meter body 1 and its bottom insulating plate 61 and pushing the new meter body 1 to the side, the arc head 63 and the insulating plate 61 are engaged with the inside of the conductive sheet 052. The new meter body 1 is engaged with the side of the wiring component 5 and the protective cover 31 is closed, so as to achieve the function of metering without interrupting power supply.
