Description

Technical Field

[0001] This utility model relates to the technical field of electricity meter monitoring devices, and in particular to an electricity meter terminal operation monitoring device. Background Technology

[0002] Currently, my country has the world's largest power coverage, so electricity meters are widely used. An electricity meter is an instrument that measures electricity consumption. With technological advancements, electricity meters are developing towards higher precision, intelligence, and green technology. Only by measuring electricity consumption can electricity costs be better calculated.

[0003] Electricity meters are generally equipped with terminals so that current flows through the meter to calculate the amount of electricity. However, wiring faults may occur at the terminals, such as poor contact or overload. Wiring faults can cause the temperature at that location to rise, further increasing the risk of insulation aging and fire. Therefore, it is necessary to detect potential faults as soon as possible to avoid danger.

[0004] Therefore, how to provide a monitoring device for the operation of electricity meter terminals is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an operation monitoring device for the wiring terminals of an electricity meter. This invention solves the problem that existing wiring terminals may experience wiring faults that lead to temperature increases, which cannot be detected in a timely manner.

[0006] A power meter terminal operation monitoring device according to an embodiment of the present invention includes a power meter body and terminals. The terminals are located at the tail end of the power meter body, and a reciprocating adjustment component is provided on the tail end face of the power meter body near the terminals. A temperature monitoring kit is provided on the reciprocating adjustment component, and the temperature monitoring kit faces the terminals.

[0007] The surface of the electricity meter body is rotatably connected to a protective cover near the tail end, which covers the wiring terminals.

[0008] The side of the energy meter body is provided with a first heat dissipation hole that communicates with the wiring terminal port, and the surface of the protective cover is provided with a second heat dissipation hole near the reciprocating adjustment component.

[0009] The reciprocating adjustment assembly includes a translation component and a drive component that provides power to the translation component.

[0010] The translation assembly includes a mounting component, a reciprocating lead screw, a guide rod, and a reciprocating movable seat. The mounting component is installed at the tail end of the energy meter body and located above the wiring terminals. The reciprocating lead screw is rotatably connected to the mounting component, the guide rod is fixedly connected to the mounting component, and the reciprocating movable seat is movably sleeved on the surfaces of the reciprocating lead screw and the guide rod. The temperature monitoring kit is set on the surface of the reciprocating movable seat.

[0011] The temperature monitoring kit includes a wireless module and a small infrared thermal imager. The wireless module is tilted and mounted on the side of the reciprocating seat, and is also mounted on the top of the reciprocating seat and connected to the small infrared thermal imager for data transmission.

[0012] The drive assembly includes a small drive motor, drive wheels, and a drive belt. The small drive motor is located on the top of the mounting component. There are two sets of drive wheels, which are fixedly connected to the end faces of the reciprocating lead screw and the output shaft of the drive motor, respectively. The two ends of the drive belt are movably sleeved on the surfaces of the two sets of drive wheels.

[0013] The mounting components include a fixed sleeve, a piston block, and a telescopic plate. The telescopic plate is fixedly connected to the tail end face of the energy meter body, the piston block is fixedly connected to the other end of the telescopic plate, the fixed sleeve is movably sleeved on the surface of the piston block, a reciprocating screw is rotatably connected to the fixed sleeve, and a guide rod is fixedly connected to the surface of the fixed sleeve.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a temperature monitoring kit, the small infrared thermal imager in the kit monitors the temperature on the terminal block and forms a monitoring image. The image information is transmitted to an external computer via a wireless module for display, thus providing a more intuitive view of the temperature. This image format is more intuitive than data and solves the problem that existing terminal block locations may have wiring faults that cause temperature rises that cannot be detected in time.

[0016] By setting up a reciprocating adjustment component, the reciprocating adjustment component will drive the temperature monitoring kit to move back and forth to patrol and monitor the temperature of the terminal block position. Only one set of temperature monitoring kits is needed to monitor a row of terminal blocks, which not only reduces costs but also improves the temperature monitoring effect.

[0017] By setting a first heat dissipation hole and a second heat dissipation hole, both of which are used to dissipate heat from the terminal block, the heat dissipation efficiency of the terminal block is improved. Attached Figure Description

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 In this embodiment, the device includes an electricity meter body 1 and a terminal block 2. The terminal block 2 is located at the tail end of the electricity meter body 1. A protective cover 5 is rotatably connected to the surface of the electricity meter body 1 near the tail end, covering the terminal block 2. A reciprocating adjustment assembly 3 is located at the tail end of the electricity meter body 1 near the terminal block 2. The reciprocating adjustment assembly 3 includes a translation assembly 8 and a drive assembly 9 that provides power to the translation assembly 8. The translation assembly 8 includes a mounting component 10, a reciprocating lead screw 11, a guide rod 12, and a reciprocating movable seat 13. The mounting component 10 is installed at the tail end of the electricity meter body 1 and is located above the terminal block 2. The reciprocating lead screw 11 is rotatably connected to the mounting component 10, and the guide rod 12 is fixedly connected to the mounting component 10. The reciprocating movable seat 13 is movably sleeved on the surface of the reciprocating lead screw 11 and the guide rod 12.

[0026] The drive assembly 9 includes a small drive motor 16, transmission wheels 17, and a transmission belt 18. The small drive motor 16 is mounted on the top of the mounting component 10. There are two sets of transmission wheels 17, which are respectively fixedly connected to the end faces of the reciprocating lead screw 11 and the output shaft of the drive motor. The two ends of the transmission belt 18 are respectively movably sleeved on the surfaces of the two sets of transmission wheels 17. During operation, the drive motor needs to be started. The rotation of the drive motor drives the transmission wheel 17 at that position to rotate, and the rotation of the transmission wheel 17 at that position will drive the transmission belt 18 to rotate. The transmission wheel 17 at another position rotates, which in turn drives the reciprocating lead screw 11 to rotate. The rotation of the reciprocating lead screw 11 drives the reciprocating movable seat 13 to move back and forth along the guide rod 12 and the reciprocating lead screw 11 on the surface of the reciprocating lead screw 11. The reciprocating movement of the reciprocating movable seat 13 drives the temperature monitoring kit 4 to move back and forth, thereby realizing patrol monitoring of a row of terminals 2. This achieves efficient monitoring of the terminals 2 without the need to set up multiple sets of temperature monitoring kits 4, reducing costs. Moreover, patrol monitoring achieves the purpose of efficient monitoring.

[0027] refer to Figure 1-4 In this embodiment, a temperature monitoring kit 4 is provided on the reciprocating adjustment component 3. The temperature monitoring kit 4 faces the terminal block 2. The temperature monitoring kit 4 includes a wireless module 14 and a small infrared thermal imager 15. The wireless module 14 is obliquely disposed on the side of the reciprocating movable seat 13 and is disposed on the top of the reciprocating movable seat 13 and connected to the small infrared thermal imager 15. Here, the small infrared thermal imager 15 is set to efficiently monitor the terminal block 2 so that the temperature is monitored in the form of an image. The monitored image data is transmitted to the wireless module 14, and then the image data is transmitted from the wireless module 14 to an external computer (not shown in the figure) for analysis and processing.

[0028] refer to Figure 1-4 In this embodiment, the side of the energy meter body 1 is provided with a first heat dissipation hole 6 that communicates with the port of the wiring terminal 2, and a second heat dissipation hole 7 is provided on the surface of the protective cover 5 near the position of the reciprocating adjustment component 3. The first heat dissipation hole 6 communicates directly with the port of the wiring terminal 2 to achieve the first step of heat dissipation, and then the second heat dissipation hole 7 dissipates heat to another part of the wiring terminal 2 on the protective cover 5, thereby improving the heat dissipation capacity at the wiring terminal 2.

[0029] refer to Figure 1-4In this embodiment, the mounting component 10 includes a fixed sleeve 19, a piston block 20, and a telescopic plate 21.

In order to change the distance between the small infrared thermal imager 15 and the terminal 2, the fixed sleeve 19 needs to be moved. The movement of the fixed sleeve 19 will drive the reciprocating adjustment component 3 to move. The movement of the fixed sleeve 19 will move on the surface of the piston block 20. After reaching a suitable position, the movement of the fixed sleeve 19 will stop. The piston block 20 stabilizes the position of the fixed sleeve 19 through damping. The movement of the reciprocating adjustment component 3 will drive the small infrared thermal imager 15 to move, thereby realizing the distance between the small infrared thermal imager 15 and the terminal 2.
