Description

Technical Field

[0001] This invention belongs to the field of electricity meter verification technology, specifically an automatic meter mounting device and method for electricity meter verification. Background Technology

[0002] An automated meter mounting device for electricity meter calibration is a piece of equipment used for the automated calibration and testing of electricity meters. It is mainly used to test the accuracy and reliability of electricity meters, and to calibrate and adjust them. Through the automated mounting device, operators can quickly and accurately install the electricity meters to be calibrated on a fixed frame, and acquire relevant parameters and measurement results through a data acquisition and processing system. Simultaneously, based on the accurate values ​​provided by the calibration standard, error calculation and adjustment are performed to ensure that the electricity meters meet precise calibration requirements. Generally, existing automated meter mounting methods involve: using AGV (Automated Guided Vehicle) carts to load and transport the electricity meters to be calibrated, equipping the AGV carts with a meter mounting robot to directly complete the unloading, transportation, and mounting operations in one go; or setting up a meter mounting robot on one side of the calibration platform to directly grab the electricity meters from the shelf to be calibrated and mount them.

[0003] However, the process of unloading and reinstalling the meter also requires connecting the meter to the calibration station, which prolongs the working time and reduces work efficiency. At the same time, the setting of multiple testing devices also increases costs and reduces the utilization rate of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic meter-hanging device and method for electricity meter verification in order to solve the problems of reduced work efficiency and increased costs mentioned above.

[0005] The technical solution adopted in this invention is as follows: An automatic meter mounting device for electricity meter calibration includes a device body. A meter mounting detection plate is provided on one side of the upper surface of the device body. Three grooves are opened from top to bottom on one side surface of the meter mounting detection plate. A detector is installed inside the groove. Several electricity meters are installed below each groove. Several storage cabinets are provided on one side surface of the device body. Through holes are opened on both sides of the lower surface of the detector. A telescopic rod base is provided inside the detector. A telescopic rod is inserted into the lower end of the telescopic rod base. A connector corresponding to the through hole is provided at the lower end of the telescopic rod. A connector corresponding to the through hole is opened on both sides of the upper surface of the electricity meter. A heat dissipation hole is provided at the lower end of one side surface of the device body.

[0006] By adopting the above technical solution and design, the insertion and connection time of the automatic meter-installing robot can be reduced. Only the electricity meter needs to be installed and removed, which improves work efficiency. At the same time, one detector can calibrate multiple electricity meters, which improves the utilization rate of the detector and saves costs.

[0007] In a preferred embodiment, a lead screw motor is installed at one end of the inner wall of the slide, a lead screw is provided at one end of the lead screw motor, a moving block is threaded onto the outer surface of the lead screw, and one end of the moving block is disposed on one side surface of the detector.

[0008] By adopting the above technical solution, the rotation of the lead screw motor can drive the moving block to move, thereby enabling the detector to move and complete the plug-in verification with the energy meter to be verified, improving convenience and flexibility.

[0009] In a preferred embodiment, a limiting rod is sleeved inside the upper and lower ends of the movable block, and the two ends of the limiting rod are disposed on the inner wall of the slide groove.

[0010] By adopting the above technical solution, the moving block is limited to prevent it from deviating during movement, which would cause the detector and the electricity meter to fail to connect properly and affect the verification results.

[0011] In a preferred embodiment, a limiting groove is formed inside the hanging meter detection plate, and a limiting block corresponding to the limiting groove is welded to the other end surface of the movable block, and the limiting block is disposed inside the limiting groove.

[0012] By adopting the above technical solution, the moving block is limited to prevent it from deviating during movement, which would cause the detector and the electricity meter to fail to connect properly and affect the verification results.

[0013] In a preferred embodiment, an infrared positioning light is provided in the middle of the lower surface of the detector, and a locator corresponding to the infrared positioning light is provided on the upper surface of the energy meter.

[0014] By adopting the above technical solution, the positioning between the infrared positioning light and the locator enables the detector and the electricity meter to be docked and verified more accurately and efficiently, thereby improving accuracy and work efficiency.

[0015] In a preferred embodiment, an operation panel is provided on the upper surface of the main body of the device, and a protective cover corresponding to the operation panel is rotatably connected to one side of the operation panel.

[0016] By adopting the above technical solution, the verification results are collected and recorded through the operation panel, and the verification is automated. The protective cover can protect the operation panel.

[0017] In a preferred embodiment, a magnetic suction element 1 is provided on one side surface of the protective cover, a magnetic suction element 2 corresponding to the magnetic suction element 1 is provided on one side surface of the operation panel, and a transparent plate is provided inside the protective cover.

[0018] By adopting the above technical solution, the magnetic attraction between magnetic component one and magnetic component two makes the protective cover close more tightly. The transparent plate can also observe the situation in the operation panel when it is closed, improving convenience and providing real-time protection for the operation panel.

[0019] In a preferred embodiment, a rubber sheet is provided on the surface of the through hole, and the same rubber sheet is provided on the surface of the insertion interface.

[0020] By adopting the above technical solution, the amount of dust and impurities in the air entering the electricity meter and tester during the calibration process is reduced, thus avoiding their impact on the calibration results, thereby improving the accuracy of the calibration results and extending the service life of the electricity meter and tester.

[0021] In a preferred embodiment, casters are mounted at the four corners of the lower surface of the device body.

[0022] By adopting the above technical solution, the main body of the device can be moved, making it convenient to move and adjust the position of the main body of the device, thus saving manpower.

[0023] In a preferred embodiment, the steps include:

[0024] Step 1: After the automatic meter-hanging robot hangs the energy meter to be tested on the surface of the meter-hanging detection plate, the lead screw motor is started to drive the lead screw to rotate. Furthermore, the moving block can move left and right in the slide groove, so that it moves above the energy meter to be tested.

[0025] Step 2: The infrared positioning light and the locator are used to locate the detector precisely above the electricity meter. Then, under the action of the telescopic rod base, the telescopic rod is pushed to extend the connector from the through hole. Finally, the connector is inserted into the socket to verify the electricity meter.

[0026] Step 3: After the verification is completed, the verification data is transmitted to the operation panel. Further, the telescopic rod base drives the connector to retract into the detector, disconnecting the connection between the detector and the energy meter. Then, driven by the moving block, it moves to the next energy meter to be verified.

[0027] Step 4: The completed electricity meter will be removed by the automatic meter-installation robot and replaced with a new electricity meter to be verified for testing. According to the above steps, the automatic process is set through the operation panel to install and verify the electricity meters in sequence, and finally the data is collected.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. During the calibration of electricity meters, the rotation of the lead screw motor drives the lead screw to rotate, which in turn allows the moving block to move left and right, thus moving the detector above the electricity meter. Positioning via an infrared positioning light and a positioner ensures the detector stops precisely above the meter. Then, pushed by the telescopic rod base, the telescopic rod causes the connector to extend from the through hole. The connector is then inserted into the socket, connecting the detector to the electricity meter for calibration. After calibration, the connector retracts into the detector, and driven by the moving block, it moves to the next meter to be calibrated. The automatic meter-mounting robot then removes the calibrated meter and mounts the new one. This design reduces the automatic meter-mounting robot's mounting time, requiring only meter mounting and unmounting, thus improving work efficiency. Furthermore, one detector can calibrate multiple meters, increasing its utilization rate and saving costs.

[0030] 2. When the connector extends or retracts, due to the properties of the rubber sheet, it will adhere to the surface of the telescopic rod when the connector extends. When the connector retracts into the tester, it will also seal the through hole. Similarly, the connector interface will be sealed. Through the above design, the entry of dust and impurities in the air into the energy meter and tester during the calibration process is reduced, avoiding their impact on the calibration results, thereby improving the accuracy of the calibration results and extending the service life of the energy meter and tester.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figure 1 and Figure 3-4 An automatic meter mounting device for electricity meter calibration includes a main body 1. A meter mounting detection plate 8 is provided on one side of the upper surface of the main body 1. Three grooves 6 are formed from top to bottom on one side surface of the meter mounting detection plate 8. A detector 7 is installed inside each groove 6. Several electricity meters 5 are installed below each groove 6. Several storage cabinets 4 are provided on one side surface of the main body 1. Through holes 13 are formed on both sides of the lower surface of the detector 7. A telescopic rod base 15 is installed inside the detector 7. A telescopic rod 17 is inserted into the end, and a connector 18 corresponding to a through hole 13 is provided at the lower end of the telescopic rod 17. The upper surface of the energy meter 5 has two corresponding connectors 20 on both sides. A heat dissipation hole 2 is provided at the lower end of one side surface of the main body 1. Through the above design, the insertion time of the automatic meter hanging robot can be reduced. Only the energy meter 5 needs to be hung and removed, which improves work efficiency. At the same time, one detector 7 can calibrate multiple energy meters 5, which improves the utilization rate of the detector 7 and saves costs.

[0040] Reference Figure 2 A lead screw motor 9 is installed at one end of the inner wall of the slide 6. A lead screw 11 is provided at one end of the lead screw motor 9. A moving block 12 is threaded onto the outer surface of the lead screw 11. One end of the moving block 12 is provided on one side surface of the detector 7. By rotating the lead screw motor 9, the lead screw 11 can drive the moving block 12 to move, thereby enabling the detector 7 to move and complete the plug-in verification with the energy meter 5 to be verified, thus improving convenience and flexibility.

[0041] Reference Figure 2 Limiting rods 10 are sleeved inside the upper and lower ends of the movable block 12. The two ends of the limiting rods 10 are set on the inner wall of the slide groove 6 to limit the movable block 12 and prevent it from deviating during movement, which would cause the detector 7 and the energy meter 5 to fail to connect properly and affect the verification results.

[0042] Reference Figure 2 and Figure 6 The inside of the meter detection plate 8 is provided with a limiting groove 27. The other end of the moving block 12 is welded with a limiting block 26 corresponding to the limiting groove 27. The limiting block 26 is set inside the limiting groove 27 to limit the moving block 12 and prevent it from deviating during movement, which would cause the detector 7 and the electricity meter 5 to fail to connect properly and affect the verification results.

[0043] Reference Figure 3-4 An infrared positioning light 14 is provided in the middle of the lower surface of the detector 7, and a locator 19 corresponding to the infrared positioning light 14 is provided on the upper surface of the energy meter 5. Through the positioning between the infrared positioning light 14 and the locator 19, the detector 7 and the energy meter 5 can be docked and verified more accurately and efficiently, thereby improving accuracy and work efficiency.

[0044] Reference Figure 1 and Figure 5 An operation panel 25 is provided on the upper surface of the main body 1 of the device. A protective cover 21 corresponding to the operation panel 25 is rotatably connected to one side of the operation panel 25. The operation panel 25 is used to collect and record the verification results and control the verification to be automated. The protective cover 21 can protect the operation panel 25.

[0045] Reference Figure 1 and Figure 5 A magnetic suction element 23 is provided on one side surface of the protective cover 21, and a magnetic suction element 24 corresponding to the magnetic suction element 23 is provided on one side surface of the operation panel 25. A transparent plate 22 is provided inside the protective cover 21. The magnetic attraction between the magnetic suction element 23 and the magnetic suction element 24 makes the protective cover 21 close more tightly. The transparent plate 22 can also observe the situation in the operation panel 25 when it is closed, improving convenience, and at the same time, it can also provide real-time protection for the operation panel 25.

[0046] Reference Figure 3-4 A rubber sheet 16 is provided on the surface of the through hole 13, and the same rubber sheet 16 is provided on the surface of the insertion interface 20. This reduces the amount of dust and impurities in the air entering the energy meter 5 and the detector 7 during the calibration process, thus avoiding their impact on the calibration results and improving the accuracy of the calibration results, thereby extending the service life of the energy meter 5 and the detector 7.

[0047] Reference Figure 1The four corners of the lower surface of the device body 1 are equipped with casters 3, which allow the device body 1 to be moved, making it convenient to move and adjust the position of the device body 1 and saving manpower.

[0048] Reference Figure 1-6 This includes the following steps;

[0049] Step 1: After the automatic meter-hanging robot hangs the energy meter 5 to be calibrated on the surface of the meter-hanging detection plate 8, the lead screw motor 9 is started to drive the lead screw 11 to rotate. Furthermore, the moving block 12 can move left and right in the slide groove 6, so that it moves above the energy meter 5 to be calibrated.

[0050] Step 2: Through the mutual sensing and positioning of the infrared positioning light 14 and the locator 19, the detector 7 is accurately stopped directly above the energy meter 5. Furthermore, under the action of the telescopic rod base 15, the telescopic rod 17 is pushed to make the plug 18 extend from the through hole 13. Further, the plug 18 is inserted into the plug interface 20 to verify the energy meter 5.

[0051] Step 3: After the verification is completed, the verification data is transmitted to the operation panel 25. Further, the telescopic rod base 15 drives the connector 18 to retract into the detector 7, disconnecting the connection between the detector 7 and the energy meter 5. Then, it moves to the next energy meter 5 to be verified by the movement block 12.

[0052] Step 4: The completed electricity meter 5 will be removed by the automatic meter-installing robot and replaced with a new electricity meter 5 to be tested. According to the above steps, the automatic process is set through the operation panel 25 to install and verify the electricity meter 5 in sequence, and finally the data is collected.

[0053] The implementation principle of the embodiments of the present invention is as follows:

[0054] During the calibration of the energy meter 5, the rotation of the lead screw motor 9 drives the lead screw 11 to rotate, which in turn allows the moving block 12 to move left and right, thereby moving the detector 7 above the energy meter 5. The infrared positioning light 14 and the positioner 19 ensure that the detector 7 stops precisely above the energy meter 5. Furthermore, under the push of the telescopic rod base 15, the telescopic rod 17 causes the connector 18 to extend from the through hole 13. The connector 18 is then inserted into the connector 20, allowing the detector 7 to connect with the energy meter 5. The connection is made so that the detector 7 can verify the energy meter 5. After verification, the connector 18 retracts into the detector 7 and moves to the next energy meter 5 to be verified under the drive of the moving block 12. Then the automatic meter hanging robot removes the verified energy meter 5 and hangs the new energy meter 5 to be verified. Through the above design, the insertion time of the automatic meter hanging robot can be reduced. It only needs to hang and remove the energy meter 5, which improves work efficiency. At the same time, one detector 7 can verify multiple energy meters 5, which improves the utilization rate of the detector 7 and saves costs.

[0055] When the connector 18 extends or retracts, due to the properties of the rubber sheet 16, it will adhere to the surface of the telescopic rod 17 when the connector 18 extends. When the connector 18 retracts into the detector 7, it will also seal the through hole 13. Similarly, the same applies to the connector 20. Through the above design, the entry of dust and impurities in the air into the energy meter 5 and the detector 7 during the calibration process is reduced, avoiding their influence on the calibration results, thereby improving the accuracy of the calibration results and thus extending the service life of the energy meter 5 and the detector 7.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
