[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, the number of technical features, or the order of their presentation. Furthermore, the use of "and / or," "and / or," or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Additionally, the technical solutions of the various embodiments can be combined, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this utility model.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] Currently, there are various types of smart meters and power equipment on the market, including single-phase smart meters, single-phase IoT meters, three-phase direct energy meters, three-phase mutual inductance energy meters, three-phase IoT meters, dedicated transformer data acquisition terminal smart devices, integrated terminal smart devices, and energy controllers. To address this, existing technology has developed a device capable of detecting multiple types of meters. This device includes multiple connection mechanisms corresponding to different meters and current isolation transformers. However, due to limitations in the length of the external conductors of the current isolation transformers, existing technologies, for ease of wiring, place the current isolation transformers on one side of the horizontal direction of the connection mechanism. This results in a larger horizontal dimension of the meter detection device, thus increasing its footprint.

[0042] In view of the above background, this utility model proposes an electricity meter testing system capable of testing multiple types of electricity meters, reducing the footprint of the electricity meter testing system, thereby reducing construction costs. (Refer to...) Figure 1 and Figure 2 In order to clearly show the internal structure, Figure 2 The workbench in this embodiment does not show the outer cover 110. The meter testing system includes: workbench 100, conveying mechanism 200, connecting mechanism 300, current isolation transformer 400, adapter 500, first conductor and second conductor.

[0043] The conveying mechanism 200 is used to convey the electricity meter. The conveying mechanism 200 includes, for example, a first driving device 210 and a conveying component 220. The conveying component 220 is configured as a conveyor belt or a conveyor roller. The electricity meter is placed directly on the conveying component 220. Alternatively, the electricity meter detection system may also include a fixture 700, which is set on the conveying component 220. The conveying component 220 can drive the fixture 700 to move. The electricity meter is loaded on the fixture 700, thereby realizing the conveying of the electricity meter.

[0044] The connection mechanism 300 is mounted on the workbench 100 and located beside the conveying mechanism 200. It is used to detect various types of meters. For example, the connection mechanism 300 includes probes 310, the distance between which is adjustable to adapt to terminals with different spacings on different meters. Alternatively, the connection mechanism 300 includes various connection components 301, such as single-phase to three-phase direct / mutual inductance compatible connection components, single-phase to terminal compatible connection components, or single-phase to energy controller compatible connection components 301. The connection components 301 are mounted on the workbench 100 and located beside the conveying mechanism 200. For example, in the horizontal direction, various connection components 301 are distributed along the direction of meter movement on one or both sides of the width of the conveying mechanism 200 (e.g., ...). Figure 1 (As shown); In the vertical direction, various connection components 301 are distributed in a single layer or multiple layers. Each connection component 301 includes several probes 310, which are used to contact the terminals of the electricity meter to test the meter. For example, the connection component 301 also includes a second driving device connected to the probes 310. When the electricity meter moves to the corresponding connection component 301, the second driving device drives the probes 310 to move toward the terminals of the electricity meter and contact the terminals to power on and test the electricity meter.

[0045] The current isolation transformer 400 is connected to the workbench 100 and is located below the connection assembly 301. The adapter 500 is located between the connection assembly 301 and the current isolation transformer 400 (e.g., Figure 2 (As shown). One end of the first wire is connected to the connector 301, and the other end is connected to the adapter 500. One end of the second wire is connected to the adapter 500, and the other end is connected to the current isolation transformer 400. Furthermore, the workbench 100 also includes an outer cover 110. The adapter 500, the current isolation transformer 400, the first wire, and the second wire are installed inside the outer cover 110, making the appearance of the meter testing system in this embodiment simpler and reducing the contact between external dust and moisture and internal components, thereby reducing the risk of short circuits.

[0046] Specifically, in this embodiment, a connection mechanism 300 for detecting various electricity meters is installed on the workbench 100 and connected to the current isolation transformer 400 via an adapter 500. Therefore, during setup, the connection component 301 can be connected to the adapter 500 via a first wire, and then the adapter 500 can be connected to the current isolation transformer 400 via a second wire. This allows for more flexible placement of the current isolation transformer 400, making wiring more convenient. Furthermore, in this embodiment, the current isolation transformer 400 is located below the connection component 301, fully utilizing vertical space to reduce the floor space occupied by the electricity meter detection system, thereby reducing the setup cost of the electricity meter detection system.

[0047] Reference Figure 3 and Figure 4 , Figure 3 for Figure 1 Left view, Figure 4 for Figure 1 In some embodiments, the electricity meter testing system includes a top view of the device. It comprises multiple layers of vertically arranged connecting mechanisms 300 and multiple layers of conveying mechanisms 200, each layer of conveying mechanism 200 corresponding to one layer of connecting mechanism 300. For example, the electricity meter testing equipment includes two conveying mechanisms 200 distributed vertically, thereby fully utilizing the vertical space within the factory building and reducing the floor space occupied by the electricity meter testing system, thus lowering the construction cost of the system.

[0048] Alternatively, in some embodiments, the meter detection system includes multiple layers of connection mechanisms 300 arranged vertically, and the conveying mechanism 200 further includes a lifting mechanism 600 for driving the meter to move up and down. Exemplarily, the lifting mechanism 600 includes a lifting tray 610 and a third driving device. The third driving device is connected to the lifting tray 610, which supports the meter. When the meter moves to the connection mechanism 300, the third driving device drives the lifting tray 610 to rise, thereby raising the meter and moving it to the corresponding connection mechanism 300 for detection. Therefore, in this embodiment, multiple layers of connection mechanisms 300 can be arranged without the need for multiple conveying mechanisms 200, thus reducing the construction cost of the meter detection system in this embodiment.

[0049] Reference Figure 4 Based on the above embodiments, the lifting mechanism 600 is stationary relative to the worktable 100 in the horizontal direction. Specifically, for example, the conveying mechanism 200 includes a support fixed to the ground, a conveying component 220 movably connected to the support, and the conveying component 220 is configured as two belts 221 spaced apart. The third driving device is fixedly connected to the support or the worktable 100 and is stationary relative to the worktable 100 in the horizontal direction. The lifting mechanism 600 also includes a lifting tray 610 connected to the third driving device and located between the two belts 221. The third driving device can drive the lifting tray 610 to move up and down to lift the meter from the belts 221 and move it to the connecting mechanism 300 for testing. Therefore, in this embodiment, the lifting mechanism 600 does not need to move with the meter, thereby reducing the energy consumption of the conveying mechanism 200 and saving meter testing costs.

[0050] Reference Figure 5 , Figure 5This is a top view of a fixture in an electricity meter testing system according to an embodiment of the present invention. In some embodiments, the electricity meter testing system further includes a fixture 700, which includes a supporting part 710 and a positioning part 720. The supporting part 710 is used to support the electricity meter, and the positioning part 720 is connected to the supporting part 710 and is used to position the electricity meter, thereby improving the stability of the electricity meter during transportation and improving the positional accuracy of the electricity meter. This ensures that when the electricity meter moves to the connecting mechanism 300, the probe 310 on the connecting mechanism 300 can make normal contact with the terminals on the electricity meter, reducing the probability of false detection. At the same time, since the electricity meter is fixed by the positioning part 720, sufficient force can be ensured between the terminal and the probe 310 when the probe 310 contacts the terminal, avoiding false detection caused by poor contact between the terminal and the probe 310. Furthermore, in some embodiments, the fixture 700 includes multiple positioning parts 720, each positioning part 720 being used to position a type of electricity meter, thereby enabling each fixture 700 to carry multiple electricity meters, thus improving the practicality of the electricity meter detection system of this embodiment.

[0051] Reference Figures 4 to 6 , Figure 6 Figure 5 A cross-sectional view of the fixture; in some embodiments, the top surface of the lifting tray 610 also includes a protrusion 611 (e.g., Figure 4 As shown), the bottom of the fixture 700 has a positioning hole 711 that matches the shape and size of the protrusion 611 (as shown). Figure 6 As shown, when the lifting tray 610 rises and lifts the fixture 700, the protrusion 611 inserts into the positioning hole 711, thereby improving the stability of the fixture 700 during its ascent and improving the positional accuracy of the meter located on the fixture 700. This allows the probe 310 of the connecting mechanism 300 to make more precise contact with the meter's terminals, thus reducing the probability of false meter detection. Furthermore, in some embodiments, the top of the protrusion 611 is a conical surface, which allows the protrusion 611 to more easily extend into the positioning hole 711 during operation, thereby reducing the construction cost of the meter 1 detection system in this embodiment.

[0052] Specifically, to improve the positional accuracy of the probe 310 and the meter terminals, the fixture 700 needs to have high positional accuracy. In some embodiments, it is necessary to ensure the positional accuracy of the fixture 700 during transport, that is, the first drive device 210 needs to have high accuracy. At the same time, to ensure that the protrusion 611 of the tray can be accurately inserted into the positioning hole 711, the installation accuracy of the lifting tray 610 also needs to be ensured. In this embodiment, the top of the protrusion 611 is a conical surface. Even if there is a certain positional error when the fixture 700 moves to the connecting mechanism 300, the protrusion 611 can still be inserted into the positioning hole 711. The position of the fixture 700 can be adjusted by the cooperation between the protrusion 611 and the positioning hole 711, thereby ensuring the positional accuracy between the fixture 700 and the connecting mechanism 300. Therefore, in this embodiment, while ensuring the positional accuracy between the fixture 700 and the connecting mechanism 300, the accuracy of the first drive device 210 can be reduced, thereby reducing the construction cost of the meter detection system. Similarly, in some embodiments, the opening of the positioning hole 711 is a tapered surface, so that the protrusion 611 can be more easily inserted into the positioning hole 711, which will not be described in detail here.

[0053] In some embodiments, the meter testing system includes multiple fixtures 700 corresponding to different types of meters, and the fixtures 700 are detachably connected to the conveying mechanism 200. Specifically, as can be seen from the above embodiments, the meter testing system of this embodiment is used to test multiple types of meters. If one fixture 700 is used to carry all the meters, the size of the fixture 700 needs to be large. However, in this embodiment, the fixture 700 is detachably connected to the first driving device 210. For example, the fixture 700 is placed on the conveying member 220 of the conveying mechanism 200 by screws, snap-fit, or directly. When testing different meters, the corresponding fixture 700 can be replaced, thereby improving the practicality of the meter testing system of this embodiment.

[0054] Furthermore, the various fixtures 700 include fixtures 700 designed to accommodate only one electricity meter, and fixtures 700 designed to accommodate multiple electricity meters simultaneously. The appropriate fixture 700 can be replaced according to actual requirements, thereby preventing the fixture 700 from being idle and thus reducing energy consumption. Specifically, for example, the electricity meter detection system of this embodiment can be used to detect three types of electricity meters, referred to as the first meter, the second meter, and the third meter, respectively. There are three types of fixtures 700: a first fixture that can accommodate all three types of electricity meters simultaneously, a second fixture that can accommodate the first and second meters, and a third fixture that can accommodate the second and third meters. Since the first fixture needs to accommodate three meters, its volume is necessarily larger than that of the second and third fixtures; that is, the weight of the first fixture is greater than the weight of both the second and third fixtures. When it is necessary to test the first, second, and third electricity meters simultaneously, the first fixture can be used, thereby enabling all three meters to be simultaneously transported to the connection mechanism 300 for testing during the testing process. When it is necessary to test the first and second electricity meters simultaneously, the first fixture can be replaced with the lighter second fixture, thereby avoiding the occurrence of empty areas (corresponding to the bearing area 730 of the third electricity meter) when using the first fixture, thus reducing energy consumption.

[0055] Reference Figure 5 In some embodiments, the fixture 700 includes a plurality of positioning portions 720, which, together with the support portion 710, form a plurality of support areas 730, enabling the fixture 700 to simultaneously accommodate multiple electricity meters. These multiple electricity meters can be of the same type or different types. For example, in some embodiments, the fixture 700 includes multiple positioning portions 720, each positioning portion 720 defining a support area 730 with the support portion 710. Each support area 730 is used to accommodate one type of electricity meter. The fixture 700 includes at least two staggered support areas 730. Exemplarily, the fixture 700 includes a third and a fourth support area that are staggered. The shape and size of the third support area are adapted to the shape and size of a single-phase smart meter, allowing the single-phase smart meter to be stably secured in the third support area. The shape and size of the fourth support area are adapted to the shape and size of a three-phase direct energy meter, allowing the three-phase direct energy meter to be stably secured in the fourth support area. Therefore, during operation, the conveying mechanism 200 can simultaneously convey single-phase smart meters and three-phase direct meters to the connection mechanism 300 for testing via the fixture 700, thereby improving the testing efficiency of the meter testing system in this embodiment.

[0056] Based on the above embodiments, the connection mechanism 300 includes multiple connection components 301, among which are a first connection component and a second connection component. The first and second connection components are located at the same height, and when the position of the third bearing area corresponds to the first connection component, the position of the fourth bearing area corresponds to the second connection component. The third bearing area is used to load a first electricity meter (e.g., a single-phase smart meter), and the first connection component is used to detect the first electricity meter, that is, the first connection component is used to check the electricity meter whose shape and size are adapted to the third bearing area. Similarly, the fourth bearing area is used to load a second electricity meter (e.g., a three-phase direct meter), and the second connection component is used to detect the second electricity meter, that is, the second connection component is used to detect the electricity meter whose shape and size are adapted to the fourth bearing area. Therefore, in the process of applying the electricity meter detection system of this embodiment to detect electricity meters, two types of electricity meters can be detected simultaneously, further improving the detection efficiency of the electricity meter detection system of this embodiment.

[0057] Reference Figure 5 In some embodiments, the various positioning portions 720 include a first positioning portion 721 and a second positioning portion 722. The first positioning portion 721 and the support portion 710 define a first support region 731, and the second positioning portion 722 and the support portion 710 define a second support region 732. The first support region 731 and the second support region 732 at least partially overlap, for example, the first support region 731 and the second support region 732 partially overlap, or the first support region 731 is located inside the second support region 732 (e.g., Figure 5(As shown), or the second bearing area 732 is located inside the third bearing area 730. The first positioning part 721 is movably connected to the bearing part 710. When the second bearing area 732 is used to carry the electricity meter, the first positioning part 721 can move relative to the bearing part 710 to avoid the electricity meter placed in the second bearing area 732. Therefore, the fixture 700 in the electricity meter testing system of this embodiment is smaller in size while being able to be used to load at least two types of electricity meters, thereby reducing energy consumption. Furthermore, when testing two different types of electricity meters, the electricity meter testing system of this embodiment can transport the two types of electricity meters without replacing the fixture 700, thereby improving testing efficiency. Specifically, the first carrying area 731 is used to load the first electricity meter, and the second carrying area 732 is used to load the second electricity meter. The area of ​​the first carrying area 731 is A, and the area of ​​the second carrying area 732 is B. If the first carrying area 731 and the second carrying area 732 are staggered, the area of ​​the fixture 700 is at least A+B. However, in this embodiment, the first carrying area 731 and the second carrying area 732 have an overlapping area, the area of ​​which is C. Therefore, under the premise that the fixture 700 can load both the first and second electricity meters, at least area C can be saved. Thus, when the electricity meter being transported includes either the first or the second electricity meter, the idle area of ​​the fixture 700 can be reduced, thereby reducing the weight of the idle area of ​​the fixture 700 and reducing the energy consumption of the conveying mechanism 200.

[0058] Similarly, in some embodiments, the second positioning part 722 is movably connected to the support part 710. When the first support area 731 is used to support the meter, the second positioning part 722 can move relative to the support part 710 to avoid the meter placed in the first support area 731. This will not be described in detail here.

[0059] Reference Figure 6 In some embodiments, the support portion 710 has a first mounting hole 712, and one end of the first positioning portion 721 is connected to the first mounting hole 712 and can move vertically relative to the support portion 710. The first positioning portion 721 can be positioned within the first mounting hole 712 under the gravity of the meter placed in the second support area 732. For example, the fixture 700 also includes an elastic portion 740, which is any elastic structure such as a compression spring or a tension spring. One end of the elastic portion 740 is connected to the support portion 710, and the other end is connected to the first positioning portion 721. When the meter is placed in the second support area 732, the meter contacts the first positioning portion 721 and transmits force to the elastic portion 740. The first positioning portion 721 can automatically retract into the first mounting hole 712 under the gravity of the meter to avoid the meter without additional operation, making the use of the fixture 700 simpler and more convenient.

[0060] Similarly, in some embodiments, the second positioning part 722 is movably connected to the support part 710, the support part 710 has a second mounting hole 713, one end of the second positioning part 722 is connected to the second mounting hole 713, and can move vertically relative to the support part 710. The second positioning part 722 can be positioned in the second mounting hole 713 under the gravity of the meter placed in the first support area 731.

[0061] In some embodiments, the connection mechanism 300 includes multiple connection components 301 corresponding to different electricity meters, and the connection components 301 are detachably connected to the workbench 100. Therefore, the testing personnel can select the appropriate connection component 301 for testing the electricity meter according to their needs, thereby further reducing the system footprint of this embodiment. Specifically, for example, the electricity meter testing system of this embodiment includes eight connection components 301, and the workbench 100 includes four mounting positions for installing the connection components 301, each mounting position for installing one connection component 301. The testing personnel can select four of the connection components 301 according to their needs. Therefore, while the electricity meter testing system of this embodiment can test eight types of electricity meters, the size of the workbench 100 can be made smaller, thereby reducing the system footprint of this embodiment.

[0062] In some embodiments, the meter testing system further includes a handling mechanism, such as a robot, a robotic arm, or a gantry gripper, which is used to pick up and drop the meter to improve the working efficiency of the meter testing system in this embodiment.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
