A high-precision intelligent electric energy metering box and system

Abstract

This invention relates to the field of metering box technology, specifically a high-precision intelligent power metering box and system. It comprises a box body, a lower sealing plate, an upper sealing plate, a back plate, side plates, and a door panel. When the operator opens the door panel, the door panel and the first column rotate. During this process, an L-shaped plate rotates with the first column, causing one end of the L-shaped plate located between the first and second columns to press against an arc-shaped plate. The arc-shaped plate, after being pressed, rotates around the second column as its center. During this rotation, the second column drives a rotating plate positioned above it to rotate. As the rotating plate rotates, it moves out from between the two support plates, thus no longer blocking the gap between them. This exposes the space on the side of the box, allowing operators to easily install and maintain the mounting points on the sides of the components.

Description

Technical Field

[0001] This invention relates to the field of metering box technology, specifically a high-precision intelligent power metering box and system. Background Technology

[0002] An electricity metering box is a special box used to install electricity meters, transformers and auxiliary equipment to realize electricity metering, data acquisition and electricity consumption monitoring. It is widely used in residential communities, industrial plants, commercial buildings and other scenarios.

[0003] The internal components of the electricity metering box are various electronic components, whose main functions include electricity metering, safety protection, and data management; all of these functions require components to function.

[0004] To achieve the functions of electricity metering, installation protection, and data management, the components inside the electricity metering box need to be installed in three main categories: core metering devices, auxiliary protection devices, and data acquisition and control devices. The process of installing these three categories inside the metering box is quite complicated, making it difficult for staff to install and maintain the devices.

[0005] In particular, most existing metering boxes use the front as the door opening and closing point, which makes it difficult to install the devices on the side, as the side of the device faces the inside of the metering box. This is especially true if the internal space of the metering box is small, which further increases the difficulty of installation.

[0006] In summary, to solve the technical problems raised in this paper, this invention proposes a high-precision intelligent power metering box and system. Summary of the Invention

[0007] To address the aforementioned issue that side mounting of devices presents a challenge due to the device's side facing the inside of the metrology box, and that this difficulty is further exacerbated by a limited internal space within the metrology box, [further details needed].

[0008] This invention proposes a high-precision intelligent power metering box, which includes a box body; the box body includes:

[0009] The box has a lower sealing plate and an upper sealing plate, with a back panel, side panels, and a door panel between them. There are two sets of side panels, each consisting of two support plates. The two sets of side panels are located at both ends of the back panel and are perpendicular to it. The two support plates on each set of side panels are distributed vertically, with a gap between them. The upper support plate is connected to the lower end of the upper sealing plate, and the lower support plate is connected to the upper end of the lower sealing plate. The door panel is located between the two sets of side panels, and the interior of the door panel, side panels, back panel, upper sealing plate, and lower sealing plate forms a box cavity.

[0010] The box door panel consists of two boxes, and each of the two boxes is provided with a No. 1 post at the far end of the two boxes. The upper and lower ends of the No. 1 post are rotatably connected to the upper and lower sealing plates, and the two boxes are fixed to the No. 1 post.

[0011] A second column is rotatably connected between the ends of two support plates away from the back plate. A rotating plate is fixed on the second column, which seals the gap between the two support plates. An arc-shaped plate is installed on the second column, located between the first and second columns. A sliding groove is provided on the first column, with an L-shaped cross-section. An L-shaped plate is slidably connected inside the groove. The two ends of the arc-shaped plate extend from the two ends of the groove, and the end of the L-shaped plate closest to the arc-shaped plate contacts the end of the arc-shaped plate facing the outside of the box. A through groove is provided in the middle of the arc-shaped plate, and the dimensions of the L-shaped plate are the same as those of the through groove.

[0012] A sealing plate is installed between column 1 and column 2. The sealing plate is slidably connected to the outside of column 1 and column 2, and the sealing plate seals the gap between column 1 and column 2. A rubber strip is installed on the side of the sealing plate that contacts column 1 and column 2.

[0013] As a preferred embodiment of this application, a drive groove is provided at both ends of the back panel. The drive groove is located in the gap between the upper sealing plate and the lower sealing plate. A drive block is slidably connected inside the drive groove by a spring. An installation groove is provided at the end of the back panel away from the door panel. A gear is rotatably connected inside the installation groove. The gear meshes with the drive block. A movable plate is slidably connected at the end of the back panel away from the door panel. The inner side of the movable plate meshes with the gear.

[0014] As a preferred embodiment of this application, a rectangular notch is provided on the inner side of the end of the movable plate near the back plate, and a rubber sealing strip is fixed inside the rectangular notch.

[0015] As a preferred embodiment of this application, the middle part of the rubber sealing strip is hollow, a limiting groove is provided at one end of the moving plate near the back plate, a sliding plate is fixed at one end of the back plate near the moving plate, the sliding plate is slidably connected inside the limiting groove, a folding airbag is provided at one end of the limiting groove near the rotating plate, and the folding airbag is connected to the inside of the rubber sealing strip through an air tube.

[0016] As a preferred embodiment of this application, a rectangular groove is provided at the lower end of the upper sealing plate and the upper end of the lower sealing plate. The rectangular groove is located at the ends of the door panels that are far apart from each other. A slider is slidably connected inside the rectangular groove. A spring is provided between the slider and the rectangular groove. The sealing plate is located between the upper and lower sliders. An adjusting block is provided on the inner side of the sealing plate. The upper end of the adjusting block is inclined. A protrusion is provided at the end of the inclined surface of the upper end of the adjusting block that is far away from the sealing plate. The adjusting block is located below the L-shaped plate. A fixing plate is fixed at the lower end of the L-shaped plate. The fixing plate is arc-shaped and has a cavity inside. A support plate is slidably connected inside the fixing plate. The support plate is arc-shaped. A pressure plate is provided at the end of the support plate that is far away from the inside of the fixing plate.

[0017] As a preferred embodiment of this application, rollers are provided below the pressure plate, and when the L-shaped plate moves downward, the rollers contact the inclined surface on the adjusting block below.

[0018] As a preferred embodiment of this application, the lower end of the L-shaped plate is provided with a telescopic device; the telescopic device is located inside the slide groove.

[0019] A high-precision intelligent energy metering box system is provided. The system is applicable to the aforementioned high-precision intelligent energy metering box. The system is characterized in that it includes a temperature sensing system and a humidity sensing system. The temperature sensing system is located below the upper sealing plate, and the humidity sensing system is located at the upper end of the upper sealing plate. The temperature sensing system and the humidity sensing system are connected to a telescopic device.

[0020] The beneficial effects of this invention are as follows:

[0021] The staff then opened the cabinet door, and the door and column one rotated. During this process, the L-shaped plate rotated with column one, causing the end of the L-shaped plate between column one and column two to press against the arc-shaped plate. After being pressed, the arc-shaped plate rotated around column two. During this process, column two rotated, which in turn caused the rotating plate above it to rotate. As the rotating plate rotated, it moved out from between the two support plates, so that the rotating plate no longer blocked the gap between the two support plates. This allowed space to be exposed on the side of the cabinet, making it easier for staff to install and repair the mounting points on the side of the components. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1:

[0035] like Figures 1 to 10 As shown; a high-precision intelligent power metering box, the metering box includes a box body 1; the box body 1 includes:

[0036] The lower sealing plate 2 and the upper sealing plate 3 are connected by a back plate 4, a side plate 5, and a door panel 6. There are two sets of side plates 5, each set consisting of two support plates 51. The two sets of side plates 5 are respectively located at both ends of the back plate 4 and are perpendicular to the back plate 4. The two support plates 51 on each set of side plates 5 are distributed vertically and have a gap between them. The upper support plate 51 is connected to the lower end of the upper sealing plate 3, and the lower support plate 51 is connected to the upper end of the lower sealing plate 2. The door panel 6 is located between the two sets of side plates 5. The interior of the door panel 6, side plates 5, back plate 4, upper sealing plate 3, and lower sealing plate 2 forms the cavity of the box body 1.

[0037] The box door panel 6 is composed of two boxes 61, and each of the two boxes 61 is provided with a No. 1 post 62 at one end away from each other. The upper and lower ends of the No. 1 post 62 are rotatably connected to the upper sealing plate 3 and the lower sealing plate 2, and the two boxes 61 are fixed on the No. 1 post 62.

[0038] A second column 52 is rotatably connected between the ends of two support plates 51 away from the back plate 4. A rotating plate 53 is fixed on the second column 52, and the rotating plate 53 seals the gap between the two support plates 51. An arc-shaped plate 54 is provided on the second column 52, and the arc-shaped plate 54 is located between the first column 62 and the second column 52. A sliding groove 63 is provided on the first column 62. The sliding groove 63 has an L-shaped cross section. An L-shaped plate 64 is slidably connected inside the sliding groove 63. The two ends of the arc-shaped plate 54 extend from the two ends of the sliding groove 63, and the end of the L-shaped plate 64 near the arc-shaped plate 54 contacts the end of the arc-shaped plate 54 facing the outside of the box 1. A through groove 55 is provided in the middle of the arc-shaped plate 54. The dimensions of the L-shaped plate 64 are the same as those of the through groove 55.

[0039] A sealing plate 7 is provided between column 1 62 and column 2 52. The sealing plate 7 is slidably connected to the outer side of column 1 62 and column 2 52, and the sealing plate 7 seals the gap between column 1 62 and column 2 52.

[0040] Both ends of the back plate 4 are provided with drive grooves 41, which are located in the gap between the upper sealing plate 3 and the lower sealing plate 2. The drive block 42 is slidably connected inside the drive groove 41 by a spring. The end of the back plate 4 away from the door panel 6 is provided with an installation groove 43. The inside of the installation groove 43 is rotatably connected with a gear 44, which meshes with the drive block 42. The end of the back plate 4 away from the door panel 6 is slidably connected with a moving plate 45, and the inner side of the moving plate 45 meshes with the gear 44.

[0041] A rectangular notch is provided on the inner side of the movable plate 45 near the back plate 4, and a rubber sealing strip 46 is fixed inside the rectangular notch.

[0042] The specific workflow is as follows;

[0043] When staff are installing or repairing the internal components of the metering box, they can hold the handle on the box door panel 6 and open both box doors 6. As the two box doors 6 are opened, they drive the two No. 1 columns 62 to rotate, and the No. 1 columns 62 drive the L-shaped plate 64 to rotate. The L-shaped plate 64 passes through the through slot 55 on the arc plate 54 without pushing the arc plate 54, thus opening the box door panel 6. After the box door panel 6 is opened, staff can install the components inside the cavity of the box body 1, thus realizing the installation and maintenance of the components inside the cavity of the box body 1.

[0044] When installing or repairing components, during the process of installing or removing components from the housing 1, the operator can control the L-shaped plate 64 to move downwards. The L-shaped plate 64 moves downwards within the slide groove 63. During this downward movement, the L-shaped plate 64 no longer aligns with the through groove 55. Subsequently, the operator opens the housing door 6, causing the door 6 and the first post 62 to rotate. During this rotation, the L-shaped plate 64 rotates with the first post 62, positioning the L-shaped plate 64 in a specific position. One end between column 62 and column 52 is pressed against the arc plate 54. After being pressed, the arc plate 54 rotates around column 52. During the process, column 52 rotates, which drives the rotating plate 53 set above it to rotate. When the rotating plate 53 rotates, it rotates out from between the two support plates 51, so that the rotating plate 53 no longer blocks the gap between the two support plates 51, thereby realizing the space on the side of the box 1 is exposed, making it convenient for staff to install and repair the mounting points on the side of the device.

[0045] Furthermore, drive grooves 41 are formed at both ends of the back plate 4, and drive blocks 42 are slidably connected inside the drive grooves 41, so that the drive blocks 42 and the drive grooves 41 are slidably connected by springs. When the door panel 6 is closed, the L-shaped plate 64 on the first post 62 no longer presses against the arc-shaped plate 54, causing the torsion spring between the second post 52 and the support plate 51 to reset. When the torsion spring resets, the rotating plate 53 resets, and the end of the rotating plate 53 away from the second post 52 moves closer to both ends of the back plate 4. During this process, the rotating plate 53 presses against the drive blocks 42 on the back plate 4, and the drive plate moves into the drive grooves 41. During this process, the drive blocks 42 and the drive blocks 42 on the back plate 4 are slidably connected by springs. Gear 44 meshes and rotates inside the mounting groove 43. Because a movable plate 45 is provided on the outer side of the back plate 4, and the inner side of the movable plate 45 meshes with the gear 44, the rotation of the gear 44 drives the movable plate 45 to move away from the back plate 4 until the ends of the two movable plates 45 that are away from each other seal the end of the rotating plate 53 that is away from the second post 52. During this process, the rubber sealing strip 46 provided on the ends of the two movable plates 45 that are away from each other squeezes and seals the end of the rotating plate 53 that is away from the second post 52, thereby achieving a seal between the end of the rotating plate 53 that is away from the second post 52 and the back plate 4; ensuring the sealing performance of the inside of the box 1.

[0046] Example 2:

[0047] like Figures 1 to 10 As shown; the middle part of the rubber sealing strip 46 is hollow, the end of the movable plate 45 near the back plate 4 is provided with a limiting groove 47, the end of the back plate 4 near the movable plate 45 is fixed with a sliding plate 48, the sliding plate 48 is slidably connected to the inside of the limiting groove 47, the end of the limiting groove 47 near the rotating plate 53 is provided with a folding airbag 49, the folding airbag 49 is connected through the inside of the air tube rubber sealing strip 46;

[0048] The specific workflow is as follows;

[0049] Based on the above embodiment, the middle part of the rubber sealing strip 46 is hollow, and a limiting groove 47 is opened at the end of the moving groove near the back plate 4. A sliding plate 48 is provided at the end of the back plate 4 near the moving plate 45. The sliding plate 48 is slidably connected inside the limiting groove 47, so that the sliding plate 48 can slide inside the limiting groove 47. Based on the first embodiment, during the process of the rotating plate 53 closing the gap between the two support plates 51, the driving block 42 moves into the driving groove 41. The driving block 42 meshes with the gear 44, the gear 44 rotates, and the gear 44 meshes with the inner side of the moving plate 45, so that the two moving plates move away from each other. During the process, the sliding plate 48 slides in the groove 63 inside the limiting groove 47. The folded airbag 49 inside the slot 47 is compressed. After being compressed, the gas inside the folded airbag 49 enters the interior of the rubber sealing strip 46 through the air tube, causing the rubber sealing strip 46 to expand. After the rubber sealing strip 46 expands, the pressure on the end of the rotating plate 53 away from the second column 52 is increased, thereby improving the sealing between the rotating plate 53 and the back plate 4. When the door panel 6 is opened, the L-shaped plate 64 on the first column 62 pushes the arc plate 54, and the rotating plate 53 no longer seals the gap between the two support plates 51. At this time, the spring between the drive block 42 and the drive groove 41 pushes the drive block 42 to reset, the two moving plates 45 move away from each other, and the folded airbag 49 extracts the gas between the rubber sealing strips 46 to achieve reset.

[0050] Example 3:

[0051] like Figures 1 to 10 As shown; a rectangular groove 8 is provided at the lower end of the upper sealing plate 3 and the upper end of the lower sealing plate 2. The rectangular groove 8 is located at the ends of the door panels 6 that are far apart from each other. A slider 81 is slidably connected inside the rectangular groove 8. A spring is provided between the slider 81 and the rectangular groove 8. The sealing plate 7 is located between the upper and lower sliders 81. An adjusting block 71 is provided on the inner side of the sealing plate 7. The upper end of the adjusting block 71 is set with an inclined surface. A protrusion 72 is provided at the end of the inclined surface of the upper end of the adjusting block 71 that is far away from the sealing plate 7. The adjusting block 71 is located below the L-shaped plate 64. A fixing plate 65 is fixed at the lower end of the L-shaped plate 64. The fixing plate 65 is arc-shaped and has a cavity inside. A support plate 66 is slidably connected inside the fixing plate 65. The support plate 66 is arc-shaped and has a pressure plate 67 at the end of the support plate 66 that is far away from the inside of the fixing plate 65.

[0052] A roller is provided below the L-shaped plate 64. When the L-shaped plate 64 moves downward, the roller contacts the inclined surface on the lower adjusting block 71.

[0053] The lower end of the L-shaped plate 64 is provided with a telescopic device 68; the telescopic device 68 is located inside the slide groove 63.

[0054] The specific workflow is as follows;

[0055] Based on the above embodiments, rectangular grooves 8 are formed at the lower end of the upper sealing plate 3 and the upper end of the lower sealing plate 2, and the rectangular grooves 8 are located at the ends of the door panels 6 that are far apart from each other. A slider 81 is slidably connected inside the rectangular grooves 8 by a spring, so that the sealing plate 7 is set between the upper and lower sliders 81. An adjusting block 71 is provided on the inner side of the sealing plate 7, and the upper end of the adjusting block 71 is set with an inclined surface. When it is necessary to install or remove the side of the device, a telescopic device 68 is provided at the lower end of the L-shaped plate 64. The telescopic device 68 is an electric telescopic rod in the prior art, and the electric telescopic rod is located inside the slide groove 63.

[0056] The operator can control the telescopic device 68 to retract, causing the L-shaped plate 64 to move downwards. During this downward movement, a fixed plate 65 located at the lower end of the L-shaped plate 64 moves downwards synchronously. The fixed plate 65 is positioned between column 1 62 and column 2 52. The support plate 66 inside the fixed plate 65 and the pressure plate 67 at the end of the support plate 66 move downwards synchronously. During this process, the lower end of the support plate 66 presses against the inclined surface at the upper end of the adjusting block 71, and the rollers at the lower end of the support plate 66 press against the upper end of the adjusting block 71. The inclined surface is pressed, and the roller rotates until the ball moves to the position of the protrusion 72. The roller is stuck by the protrusion 72 and cannot move downward. During the process, the ball reduces the friction between the pressure plate 67 and the upper inclined surface of the adjusting block 71. After the inclined surface on the adjusting block 71 is pressed, the adjusting block 71 will move away from the back plate 4. During the process, the slider 81 slides inside the rectangular groove 8, and the closing plate 7 moves away from the back plate 4, so that a gap is generated between the closing plate 7 and the first column 62 and the second column 52.

[0057] When column 62 rotates, L-shaped plate 64 rotates synchronously, and fixed plate 65 rotates at the same time. During the process, the lower end of pressure plate 67 is limited by protrusion 72 on adjusting block 71, so that pressure plate 67 cannot rotate, and thus pressure plate 67 slides out from fixed plate 65, so that pressure plate 67 keeps pressing on the inclined surface of adjusting block 71 until the door panel 6 and rotating plate 53 are opened.

[0058] During the opening of the door panel 6 and the rotating plate 53, there is a gap between the first column 62 and the second column 52 and the closing plate 7. This ensures that when the first column 62 and the second column 52 rotate, their surfaces do not contact the inner side of the closing plate 7. This prevents solid impurities on the outer parts of the first column 62 and the second column 52, after prolonged outdoor placement, from contacting the inner side of the closing plate 7, thus improving the smoothness of their rotation. When the door panel 6 is closed, the support plate 66 returns to its original position. Inside the fixed plate 65, the telescopic device 68 causes the L-shaped plate 64 to move upward inside the slide groove 63. The fixed plate 65 and the support plate 66 move upward synchronously, no longer pressing the inclined surface on the adjusting block 71. The spring inside the rectangular groove 8 pushes the slider 81 and the sealing plate 7 to move towards the back plate 4. The sealing plate 7 is in close contact with the surfaces of the first column 62 and the second column 52, thus sealing the gap between the first column 62 and the second column 52. The sealing strip between the sealing plate 7 and the first column 62 and the second column 52 ensures the airtightness.

[0059] Example 4:

[0060] like Figures 1 to 10 As shown; a high-precision intelligent energy metering box system, the system is applicable to the above-mentioned high-precision intelligent energy metering box, the system includes a temperature sensing system and a humidity sensing system, the temperature sensing system is set inside the lower end of the upper sealing plate 3, the humidity sensing system is set at the upper end of the upper sealing plate 3, and the temperature sensing system and the humidity sensing system are connected to the telescopic device 68.

[0061] The specific workflow is as follows;

[0062] By setting a temperature sensing system at the lower end of the upper sealing plate 3, the temperature sensing system is located inside the cavity of the box 1, which is composed of the upper sealing plate 3, the lower sealing plate 2, the door panel 6, the back panel 4, the rotating plate 53, and the support plate 51. The temperature sensing system can monitor the temperature inside the cavity of the box 1 in real time. When the temperature inside the cavity of the box 1 is high, the temperature sensing system controls the telescopic device 68 to retract downward. The telescopic device 68 drives the L-shaped plate 64 to move downward inside the slide groove 63. The fixing plate 65 and the pressure plate 67 at the lower end of the L-shaped plate 64 move downward. The lower end of the pressure plate 67 presses the inclined surface on the adjusting block 71, so that the adjusting block 71 pushes the slider 81 and the sealing plate 7 to move away from the back panel 4. This creates a gap between the sealing plate 7 and the first column 62 and the second column 52, so that the sealing plate 7 no longer seals the first column 62 and the second column 52. Thus, the gas inside the cavity of the box 1 can flow out from the gap between the first column 62 and the second column 52, thereby achieving heat dissipation inside the cavity of the box 1.

[0063] During the heat dissipation process, if the humidity sensing system detects an increase in humidity in the outside air, such as during rainy weather, it controls the telescopic device 68 to extend upward, causing the L-shaped plate 64, the fixed plate 65, and the pressure plate 67 to return to their original positions. The sealing plate 7 then re-seales the gap between the first column 62 and the second column 52, thereby preventing external moisture from entering the cavity of the housing 1.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
