Description

Technical Field

[0001] The utility model relates to the technical field of electric quantity recording, in particular to a time-sharing and phase-sharing electric quantity recording device. Background Art

[0002] In the metering operation and maintenance work, many links such as periodic rotation, fault replacement, and calibration replacement require the replacement of electric energy meters without power outage. In order to ensure that users have uninterrupted power supply and guarantee the quality of power supply, it is often necessary to replace the meter with power on site. During the meter replacement period, users use electricity normally, but the electric energy meter cannot measure during the meter replacement period, resulting in power loss. During this period, the loss of electric energy is usually compensated by the power supply bureau and the user through negotiation of electricity. The compensation method includes obtaining it through the historical power consumption characteristic curve of the electric energy metering system or through various algorithm fitting.

[0003] The result of this calculation is a result that both parties are forced to accept, and has nothing to do with the actual electricity consumption data at the time. Based on this, in order to get as close as possible to the actual electricity consumption compensation, a time-sharing and phase-sharing electricity recorder came into being, which can realize the device that can replace the electricity meter without power outage and can measure continuously.

[0004] Some of the existing live meter replacement operations are carried out outdoors. In order to restore power supply as soon as possible, outdoor operations must be carried out even if the working environment is poor, such as often working on rainy days. When working on rainy days, although umbrellas and other shielding objects can be used to achieve a certain degree of shielding, there will still be situations where rain falls on the time-sharing and phase-splitting power recording device, and the falling rain may enter the time-sharing and phase-splitting power recording device through various interfaces and gaps, or due to some accidents, liquid is spilled on the time-sharing and phase-splitting power recording device and enters the time-sharing and phase-splitting power recording device through various interfaces and gaps, which may cause damage to internal components. The existing time-sharing and phase-splitting power recording device generally only has an upper cover plate at the top opening of the box body, and the display screen, current interface, voltage interface, etc. are arranged on the upper cover plate. At this time, if liquid spills on the upper cover plate, it may enter the box body through these interfaces, installed gaps, etc. Since there are no waterproof measures inside the box body, the liquid that enters may contact the internal components and cause damage to the internal components.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Please refer to Figures 1 to 10 A preferred embodiment of the utility model provides a time-sharing and phase-sharing electric quantity recording device, which mainly includes a box body 10, an upper cover plate 20 and a box cover 60.

[0042] The box body 10 is in the shape of a square frame as a whole, with an open top and a cavity inside to accommodate various parts. A partition 30 is provided inside the box body 10 so that the box body 10 can be divided into an upper chamber 11 and a lower chamber 12, and through the isolation effect of the partition 30, a barrier can be achieved, which can effectively prevent liquid from entering the lower chamber 12. In a specific example, the parts of the time-sharing and phase-sharing electric quantity recording device that need to be waterproof but do not need to be installed on the upper cover 20 can be placed in the lower chamber 12. For example, in this exemplary embodiment, a single-chip microcomputer, a three-phase electric energy metering chip, a power module, a three-phase current collector, a three-phase voltage collector, a charging module, a power module, a storage module, a network transmission module, an alarm module, an identity recognition module, etc. are placed in the lower chamber 12. The partition 30 is in the form of being high in the middle and low on both sides, which can help the liquid entering the partition 30 to flow spontaneously to the lower sides of the partition 30. The partition 30 is provided with drainage ports 31 penetrating the box body 10 on both lower sides, and the drainage ports 31 are arranged downward to effectively prevent external impurities, such as liquid, dust, etc., from entering through the drainage ports 31. The drainage ports 31 are used for drainage. It can be understood that in order to effectively prevent external impurities from entering the box body 10 through the drainage ports 31, the drainage ports 31 should be as small as possible while meeting the drainage requirements.

[0043] The upper cover plate 20 is disposed at the top of the upper chamber 11 and at the top of the box body 10 to cover the top opening of the box body 10. In a preferred embodiment, sealing rings are provided around the side edges of the upper cover plate 20 to achieve a certain degree of waterproofing. In this preferred embodiment, the touch display module 23, the three-phase current interface 21, the three-phase voltage interface 22, and the printer 24 are disposed on the upper cover plate 20, and these components are partially located in the upper chamber 11.

[0044] During implementation, when liquid is spilled onto the upper cover 20, the liquid may enter the interior of the box 10 downward through the installation gaps of the touch display module 23, the three-phase current interface 21, the three-phase voltage interface 22, and the printer 24. At this time, the liquid entering the interior of the box 10 will flow onto the partition 30. At this time, it enters the upper chamber 11. The partition 30 is in the form of high in the middle and low on both sides. Therefore, the liquid will flow to the lower sides of the partition 30 and finally flow out through the drain port 31, and no longer flow downward into the lower chamber 12. At this time, the parts in the lower chamber 12 will not contact with the liquid, thereby effectively avoiding the liquid from contacting the parts in the lower chamber 12, and effectively avoiding these parts from being damaged by water; on the other hand, fast and efficient drainage can effectively discharge the liquid, and can also reduce the contact time and contact probability between the liquid and some parts, and can also effectively avoid these parts from being damaged by water. The time-sharing and phase-sharing electric quantity recording device of the utility model can effectively avoid some parts located inside the device from being damaged by water, and effectively solves the problem that liquid entering the interior of the device easily causes damage to internal parts.

[0045] In a preferred embodiment, please refer to Figures 2 to 3 The edges of the partition 30 are provided with side panels 32 extending upward to form a frame-like structure with an open top, and the top of the side panel 32 has a snap-on opening 33 bent outward so as to be able to match and snap into the top of the box body 10. By providing the snap-on opening 33, on the one hand, the installation of the partition 30 can be facilitated, and it only needs to be matched and snapped into the top of the box body 10 through the snap-on opening 33. On the other hand, due to the provision of the snap-on opening 33, the outer side of the snap-on opening 33 is convenient to be lower than the top edge of the box body 10 after installation. Therefore, effective waterproofing can be achieved, making it difficult for liquid to enter the box body 10 through the gap between the snap-on opening 33 and the box body 10, so as to achieve good waterproofing.

[0046] The box body 10 is provided with a through groove 13 extending upward to the top at a position corresponding to the drain port 31. The side plates 32 on both sides of the partition 30 are respectively provided with drain strips 34. The drain strips 34 are flat plate-shaped structures. The drain strips 34 are matched and inserted into the through groove 13, and the bottom of the drain strips 34 is lower than the bottom of the through groove 13. The drain port 31 is provided on the drain strips 34. The entrance of the drain port 31 is provided at the connection position between the partition 30 and the side plate 32, and the exit is provided at the bottom of the drain strips 34. The through groove 13 and the drain strips 34 are provided to adapt to the partition 30 to be installed on the box body 10 and to provide the drain port 31 extending through the box body 10. The width of the outer side surface of the drain strips 34 is greater than the width of the through groove 13, so that the outer side surface of the drain strips 34 covers the through groove 13 completely to prevent external impurities from entering the box body 10 through the through groove 13, and the outer side of the drain strips 34 is tightly fitted to the outer side of the box body 10.

[0047] A plurality of placement blocks 35 are arranged on the inner side of the side plate 32. At this time, when the upper cover plate 20 is installed, it is placed on the placement blocks 35 to achieve support through the placement blocks 35. At this time, the top surface of the upper cover plate 20 is flush with the bayonet 33 of the side plate 32, and a sealing ring is arranged around the side edge of the upper cover plate 20 to achieve a certain degree of waterproofing. Through the structural form of the partition plate 30 and the arrangement of the upper cover plate 20, the partition plate 30, the upper cover plate 20 and the box body 10 can be easily disassembled and assembled, and installation and maintenance are convenient.

[0048] The partition plate 30 is provided with a wiring opening 40 extending upward at a higher middle position. The wiring opening 40 is provided with an extension section 41 extending laterally at the top end. A wiring port 42 is provided at the end of the extension section 41 . The components in the lower chamber 12, such as a single-chip microcomputer, a three-phase electric energy metering chip, a power module, a three-phase current collector, a three-phase voltage collector, a charging module, a power module, a storage module, a network transmission module, an alarm module, an identity recognition module, etc., may need to be electrically connected to the components in the upper chamber 11, such as a touch display module 23, a three-phase current interface 21, a three-phase voltage interface 22 and a printer 24, through signal lines, power lines, etc., to achieve power supply, signal interaction, etc. Based on this, an upwardly extending wiring opening 40 is provided at a higher middle position of the partition 30, and wiring is achieved through an extension section 41 extending from the side and a wiring port 42 opened at the end of the extension section 41, so that signal lines, power lines, etc. can be laid out from a higher position of the partition 30, which can effectively prevent liquids from entering the lower chamber 12 through the opening through which the signal lines, power lines, etc. pass.

[0049] A connector 50 is detachably installed at the wiring port 42. One end of the connector 50 is plugged into the wiring port 42, and a connector outlet 51 is provided on the bottom surface of the other end. Considering that liquid may flow downward along the signal line, power line, etc., a connector 50 is provided, and a connector outlet 51 is provided on the bottom surface of the connector 50. When the cable is connected from the connector outlet 51, the cable will be bent, and then pass upward through the connector outlet 51 to enter the connector 50 and then enter the wiring port 42. Through this bend, the liquid can temporarily accumulate at this position and then drip downward without flowing along the cable, which can effectively prevent the liquid from entering the lower chamber 12 along the cable. At the same time, by providing a detachable connector 50, it is easy to thread the cable. After the threading is completed, the connector 50 is installed, which is simple and convenient.

[0050] In a preferred embodiment, the time-sharing and phase-sharing electricity quantity recording device also includes a box cover 60, which is rotatably mounted on the box body 10 via a hinge 66 so that it can be opened to a certain angle and can be closed on the top of the box body 10. A limiting portion 67 is provided on one side of the hinge 66 so that when the box cover 60 is opened to a certain angle, it abuts against the limiting portion 67 and cannot continue to open.

[0051] A first shielding plate 61 is rotatably mounted on the inner side of the box cover 60, and a second shielding plate 62 is rotatably mounted at the end of the first shielding plate 61, and when the first shielding plate 61 and the second shielding plate 62 are unfolded, they can be located above the upper cover plate 20. During implementation, by opening the box cover 60 to a certain angle, and then unfolding the first shielding plate 61 and the second shielding plate 62, the first shielding plate 61 and the second shielding plate 62 are located above the upper cover plate 20, so as to achieve a certain shielding of the upper cover plate 20. The shielding can be rainproof to achieve rainproof and waterproof, or it can be shading when the light is strong. For example, considering that the viewing effect of the touch display module 23 is poor when the light is strong, shading is used to improve the viewing experience and enhance the use experience.

[0052] In a preferred embodiment, a limit frame 70 is rotatably installed on the inner side of the box cover 60, and a plurality of limit openings 63 are arranged on the lower side of the first baffle 61. The limit openings 63 are distributed along the length direction of the first baffle 61 and are arranged side by side on both sides. The limit frame 70 has a limit rod 71. The limit frame 70 can be rotated to a certain angle and the limit rod 71 can be correspondingly inserted into a corresponding limit opening 63 to limit the first baffle 61 to a certain position. At this time, the first baffle 61 cannot be rotated. Figure 7 , Fig. 9 and Fig.10 shown.

[0053] A locking mechanism is provided at the connection between the first baffle 61 and the second baffle 62, so as to fix the first baffle 61 and the second baffle 62 at a certain angle through the locking mechanism. In this exemplary embodiment, through holes are provided at both sides of the end of the first baffle 61, and rotating rods 65 inserted into the through holes are correspondingly provided at both sides of the second baffle 62, and threads are provided at the ends of the rotating rods 65. The locking mechanism is a butterfly nut 68, and the butterfly nut 68 is screwed into the threaded part of the rotating rod 65 to tighten the first baffle 61 and the second baffle 62, so that the first baffle 61 and the second baffle 62 are fixed at a certain angle and cannot be moved.

[0054] At this time, the positions of the first baffle 61 and the second baffle 62 can be controlled and fixed at a certain angle to achieve shielding of a specific position and adjust the position to avoid affecting use.

[0055] A knob 90 is rotatably installed on the inner side of the box cover 60, so that when the first baffle 61 and the second baffle 62 are rotated, folded and attached to the inner side of the box cover 60, the knob 90 can press the first baffle 61 and the second baffle 62 so that the first baffle 61 and the second baffle 62 cannot be unfolded, thereby preventing the first baffle 61 and the second baffle 62 from shaking and unfolding when the first baffle 61 and the second baffle 62 are not needed to be unfolded.

[0056] The first shielding plate 61 has two sides with receiving grooves, in which the pull-out plates 80 are inserted. The second shielding plate 62 has two sides with receiving grooves, in which the pull-out plates 80 are inserted. When in use, the pull-out plates 80 can be pulled out from both sides, so as to expand the shielding range by setting the pull-out plates 80. Fig. 9 As shown, when not in use, the pull-out plate 80 can be hidden in the receiving groove of the first shield plate 61 or the second shield plate 62, as shown in FIG. Figure 7 shown.
