Technical Field
[0001] This utility model relates to the field of electricity meter calibration, and more specifically, to a novel smart electricity meter calibration device. Background Technology
[0002] An electricity meter is an instrument used to measure electrical energy. It is also called an electricity meter, kilowatt-hour meter, or kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. When using an electricity meter, it is important to note that under low voltage and low current conditions, the electricity meter can be directly connected to the circuit for measurement. However, under high voltage or high current conditions, the electricity meter cannot be directly connected to the line and must be used in conjunction with a voltage transformer or current transformer.
[0003] For example, the Chinese utility model patent with publication number CN219842551U allows the user to place the energy meter into the placement slot and then use a first limiting plate and a second limiting plate to limit and fix the energy meter. However, when placing the energy meter, it is necessary to rely on the downward movement of the energy meter to push the first limiting plates on both sides to unfold, which increases the difficulty of placement. In addition, the first limiting plate will rub against the side of the energy meter during the placement process, which may damage the surface of the energy meter. At the same time, after the energy meter is placed, it is necessary to use an electric telescopic rod to push the second limiting plate to complete the secondary positioning. At this time, the horizontal movement of the energy meter will also rub against the first limiting plate, which has certain shortcomings. In view of this, we propose a new type of smart energy meter calibration device. Utility Model Content

The limiting block 11 contacts the side surface of the displacement plate 6 away from the center of the base plate 1. A positioning component is provided on the top plate 3. Through the cooperation between the base plate 1, column 2, top plate 3, fixing plate 4, guide rod 5, displacement plate 6, first spring 7, limiting plate 8, roller 9, second spring 10, limiting block 11 and other structures, the energy meter is quickly and accurately positioned and fixed, effectively avoiding damage to the surface of the energy meter due to friction. At the same time, it provides buffer protection and realizes automatic reset of the positioning structure, reducing the difficulty of placing the energy meter.
[0030] Example 2
[0031] The novel smart energy meter calibration device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the positioning assembly includes an electric telescopic rod 12 as a drive source. The electric telescopic rod 12 is fixedly connected to the upper surface of the top plate 3. The telescopic end of the electric telescopic rod 12 slides through to the lower surface of the top plate 3. The telescopic end of the electric telescopic rod 12 is fixedly connected to a mounting plate 13 for component installation. A connector 14 is provided on the lower surface of the mounting plate 13. An L-shaped rod 15 for connection is fixedly connected to the surface of the mounting plate 13. A third spring 16 is fixedly connected to the lower surface of the L-shaped rod 15. A pressing plate 17 for pushing the displacement plate 6 to move is fixedly connected to the lower end of the third spring 16.
[0032] The extrusion plate 17 is inclined, and a sliding rod 18, which serves as a limiter, is fixedly connected to the upper surface of the extrusion plate 17. The upper end of the sliding rod 18 slides through to the upper surface of the L-shaped rod 15. A cleaning groove 19 is provided on the front surface of the base plate 1, and a placement groove 20 for placing an electricity meter is provided on the upper surface of the base plate 1, which communicates with the inside of the cleaning groove 19. A collection groove 21 is provided on the front surface of the base plate 1, and a collection drawer 22 for collecting and storing debris is slidably connected inside the collection groove 21. A through groove 23 communicating with the inside of the collection groove 21 is provided on the bottom wall of the cleaning groove 19. A rotating shaft 24 is rotatably connected between the inner walls on both sides of the lower part. A handle 25 and a cleaning rod 26 are fixedly connected to the rotating shaft 24. Through the cooperation of the electric telescopic rod 12, mounting plate 13, connector 14, L-shaped rod 15, third spring 16, squeezing plate 17, sliding rod 18, cleaning groove 19, placement groove 20, collection groove 21, collection drawer 22, through groove 23, rotating shaft 24, handle 25, cleaning rod 26 and other structures, the automatic positioning and stable fixation of the smart energy meter calibration are realized. At the same time, the internal cleaning of the placement groove 20 and the collection of debris are completed, ensuring a clean calibration environment and simplifying the calibration operation process.
[0033] Among them, the elastic force of the third spring 16 is greater than that of the second spring 10 and the first spring 7, and the elastic force of the second spring 10 is less than that of the first spring 7.
[0034] The usage process of the novel smart energy meter calibration device provided by this utility model is as follows:
[0035] When calibrating the electricity meter, the meter is first placed inside the placement slot 20. Then, the mounting plate 13 is lowered by activating the electric telescopic rod 12. As the mounting plate 13 descends, the pressing plate 17 moves downward simultaneously with the help of the L-shaped rod 15 and the third spring 16. The pressing plate 17 is restricted to vertical movement by the sliding rod 18. Therefore, when the inclined surface of the pressing plate 17 contacts the displacement plate 6, it pushes the displacement plate 6 towards the center of the base plate 1. In turn, the simultaneous retraction of multiple displacement plates 6 drives the limiting plate 8 to position the electricity meter. At the same time, the roller 9 helps to prevent friction between the electricity meter and the displacement plate 6. The first spring 7 is compressed after the limiting plate 8 contacts the electricity meter, thus providing a certain amount of buffer. The presence of the third spring 16 can prevent the limiting plate 8 from moving due to slight up and down fluctuations of the mounting plate 13, thereby improving the stability during the fixing process. After the mounting plate 13 is raised, the displacement plate 6 can be pulled back to its original position by the elastic force of the second spring 10. At the same time, in order to ensure that the electricity meter is in a horizontal position after placement, the handle 25 can be turned before placement. The handle 25 drives the cleaning rod 26 to make a circular motion, thereby cleaning the inside. The cleaned debris can fall into the inside of the collection drawer 22 through the through groove 23 for easy collection.
