[0002] The power metering equipment is a device for measuring, recording and controlling power consumption in the power system, and the electric energy meter is a relatively common power metering equipment. At present, the electric energy meter with a wiring terminal needs to be tested by the power metering equipment detection table body before leaving the factory to ensure the stability of the electric energy meter wiring terminal electrical connection.

[0003] A patent of China discloses an electric energy meter test table (authorized publication number CN205826855U), different wiring terminal modules are selected according to different electric energy meters, the wiring terminal module is detachably installed on the test table base, the first terminal of the test table base and the second terminal of the wiring terminal module are in interference fit, and the two are tightly connected together to realize stable electrical connection. The back plate of the test table base is inclinedly arranged, and the electric energy meter leans against the back plate. The back plate can be installed on the pedestal by bolts, or the back plate and the pedestal are integrally formed. The probe of the wiring terminal module is inserted into the input end of the electric energy meter to realize the electrical connection between the wiring terminal module and the electric energy meter, without the need of connecting the wiring terminal module and the electric energy meter by wires, which avoids the trouble of connecting multiple wires. The input ends of different electric energy meters are arranged differently, and only the wiring terminal module needs to be replaced and the corresponding output voltage needs to be adjusted to perform power-on detection on different electric energy meters, so that power-on detection on multiple electric energy meters can be realized on one electric energy meter detection table.

[0004] Although the above-mentioned device adopts the preset probe to avoid the burden of connecting the external test wire with the electric energy meter, the staff still needs to actively dock the probe with the electric energy meter input port, which requires the tester to have relatively mature plugging experience, otherwise the probe may be bent due to misalignment, or the electric energy meter input port may be damaged due to misalignment, which increases the difficulty of electric energy meter testing.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0047] The probe module 300 comprises a mounting strip fixedly connected to the surface of the electric energy meter calibrator 200 by bolts, the top of the mounting strip is fixedly connected with uniformly distributed probes, the specifications, number and position arrangement of the probes need to be customized according to the position of the terminal port of the electric energy meter to be tested, and the specific specifications, number and position arrangement need to be selected according to actual needs, which will not be described here, and the interface of the probe and the electric energy meter calibrator 200 is electrically connected by wires; when the probe and the electric energy meter terminal are connected together, the electric energy meter calibrator 200 is connected with the electric energy meter through the wires and the probe at this time, and the staff can test the specific parameter performance of the electric energy meter through the existing test method through the electric energy meter calibrator 200.

[0048] As Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 ​As shown, the automatic guiding mechanism 400 comprises a central guiding mechanism 410 fixedly connected to the top of the electric energy meter calibrator 200, the surface of the central guiding mechanism 410 is fixedly connected with a first sliding frame 420, the inner side of the first sliding frame 420 is slidingly connected with a second sliding frame 430, the inner side of the second sliding frame 430 is slidingly connected with a sliding sleeve 440, the inner side of the sliding sleeve 440 is rotationally connected with a correction sleeve 450, and the correction sleeve 450 is sleeved on the surface of the probe module 300; the horizontal cross-sectional shape of the first sliding frame 420 is U-shaped, the opening cross-sectional dimension of the first sliding frame 420 is the same as the vertical cross-sectional dimension of the second sliding frame 430, and the staff can quickly install a corresponding number of correction sleeves 450 according to the needs of the probe, so as to meet the straightening needs of different numbers of probes.

[0049] In the lifting process of the mounting plate 412, the mounting plate 412 drives the first sliding frame 420 to lift, the first sliding frame 420 drives all the second sliding frames 430 to lift, the second sliding frames 430 drive the sliding sleeve 440 to lift, the sliding sleeve 440 drives the correction sleeve 450 to lift, and the correction sleeve 450 lifts along the surface of the probe; when the probe is locally bent or deviated, the correction sleeve 450 straightens the probe through extrusion force in the lifting process, so that the probe can be vertically inserted into the socket of the electric energy meter terminal;

[0050] When the staff needs to adjust the position of the correction sleeve 450 according to the position of the probe, the staff only needs to manually control the electric cylinder 411 to drive the mounting plate 412 to rise, the mounting plate 412 drives the first sliding frame 420 to rise, the first sliding frame 420 drives all the second sliding frames 430 to rise, the second sliding frames 430 drive the sliding sleeve 440 to rise, and the sliding sleeve 440 drives the correction sleeve 450 to rise above the probe; at this time, the staff can adjust the horizontal coordinates of the correction sleeve 450 by sliding the second sliding frame 430 in the first sliding frame 420, and adjust the vertical coordinates of the correction sleeve 450 by sliding the sliding sleeve 440 in the second sliding frame 430, so as to meet the correction needs of probes at different positions.

[0051] As Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the surface of the correction sleeve 450 is provided with a spiral groove 451, and the automatic guide mechanism 400 further comprises a cleaning mechanism 460, which comprises a ring-shaped polishing sleeve 461 and a rectangular rod 462. The ring-shaped polishing sleeve 461 is embeddedly installed on the inner side of the correction sleeve 450, and the rectangular rod 462 is fixedly connected to the bottom of the sliding sleeve 440. The surface of the rectangular rod 462 is sleeved with a rectangular sleeve 463 which is in contact with the electric energy meter verifier 200. The surface of the rectangular sleeve 463 is fixedly connected with a guide block 464 which is in sliding connection with the spiral groove 451. The cleaning mechanism 460 uses the lifting trend of the correction sleeve 450 to drive the correction sleeve 450 to rotate and polish and peel off the uneven places on the probe surface caused by rust or excessive current, etc. And it can intercept and retain the polishing debris inside the correction sleeve 450, so that the smooth and clean probe is locally plugged together with the electric energy meter, further improving the stability when the electric energy meter is connected with the electric energy meter verifier 200. At the same time, the correction sleeve 450 rotates and presses the curved part of the probe, which can also reduce the burden of the correction sleeve 450 on the straightening of the probe, effectively reducing the probability of deformation of the correction sleeve 450 at a certain place due to long-term extrusion of the probe, thereby prolonging the service life of the correction sleeve 450.

[0052] A rubber spring 465 is arranged between the rectangular rod 462 and the rectangular sleeve 463, which is in a compressed state at this time, which can ensure that the rectangular sleeve 463 is always tightly fitted on the surface of the electric energy meter verifier 200, so that the correction sleeve 450 can rotate stably during lifting; The inner side of the correction sleeve 450 is provided with an annular cavity 452, and the ring-shaped polishing sleeve 461 is embeddedly installed in the inner side of the annular cavity 452, which can concentrate and retain the impurities polished from the surface of the probe together, which can not only reduce the probability of external pollution, but also facilitate subsequent centralized cleaning by the staff; The vertical sectional shape of the ring-shaped polishing sleeve 461 is in the shape of a sandglass, and the ring-shaped polishing sleeve 461 is a butyronitrile rubber material component, which can ensure that the ring-shaped polishing sleeve 461 can surround and elastically polish the protruding part of the probe, so that the probe can normally pass through the correction sleeve 450; The surface of the ring-shaped polishing sleeve 461 is sleeved with an air bag ring 466, which is in an inflated state at this time, which can increase the polishing pressure of the ring-shaped polishing sleeve 461 on the surface of the probe, to improve the polishing effect of the impurities on the surface of the probe;

[0053] In the process of lifting the correction sleeve 450 driven by the sliding sleeve 440, the sliding sleeve 440 synchronously drives the rectangular rod 462 to lift, at this time, the relative position of the rectangular rod 462 and the rectangular sleeve 463 changes, the rubber spring 465 synchronously pushes against the rectangular sleeve 463 to make the rectangular sleeve 463 abut against the surface of the electric energy meter checker 200, in this process, the relative position of the rectangular sleeve 463 and the correction sleeve 450 changes, the correction sleeve 450 rotates along the sliding sleeve 440 under the guidance of the guide block 464 through the spiral groove 451, and the correction sleeve 450 drives the annular polishing sleeve 461 to flexibly and rotationally polish the local part of the probe, which can quickly polish the uneven part of the probe surface caused by rust or excessive current, which can increase the effective contact area of the probe and the terminal of the electric energy meter, and make the connection between the electric energy meter checker 200 and the electric energy meter more stable.

[0054] As shown in Figure 4 and Figure 9 , the center guiding mechanism 410 includes an electric cylinder 411 fixedly connected to the top of the electric energy meter checker 200, the surface of the electric cylinder 411 is fixedly connected with a mounting plate 412, the first sliding frame 420 is fixedly connected to the bottom of the mounting plate 412, the surface of the mounting plate 412 is provided with a sliding cavity 413, the inner side of the sliding cavity 413 is rotationally connected with a bidirectional screw rod 414, the surfaces of the two opposite threads of the bidirectional screw rod 414 are both threadedly connected with a threaded sleeve 415 slidingly connected with the sliding cavity 413, one end of the threaded sleeve 415 penetrates out of the sliding cavity 413, one end of the threaded sleeve 415 is fixedly connected with a clamping plate 416, the two clamping plates 416 are symmetrically distributed on the two sides of the center point of the mounting plate 412, the bottom of the mounting plate 412 is fixedly connected with a servo motor 417, the end of the output shaft of the servo motor 417 and the surface of the bidirectional screw rod 414 are both fixedly connected with intermeshingly connected bevel gears 418, the center guiding mechanism 410 can self-calibrate the relative position of the electric energy meter and the probe module 300, and can automatically drive the electric energy meter and the probe module 300 to be plugged or separated, so as to achieve the purpose of automatic operation.

[0055] The vertical sectional shape of the sliding cavity 413 and the contact part between the threaded sleeve 415 and the sliding cavity 413 are both matched rectangles, which can prevent the threaded sleeve 415 from rotating together with the bidirectional screw rod 414, so as to ensure that the clamping plates 416 can smoothly approach or move away from the electric energy meter; the opposite ends of the two clamping plates 416 are both provided with resistance increasing grooves 419, and the edges and corners of the clamping plates 416 and the resistance increasing grooves 419 are all rounded, which can increase the clamping friction of the clamping plates 416 on the resistance increasing grooves 419, so as to improve the stability of the plugging or separation of the electric energy meter and the probe module 300.

[0056] When the staff needs to lock the electric energy meter, the staff only needs to manually control the servo motor 417 to rotate in the corresponding direction, the servo motor 417 drives the bevel gear 418 connected thereto to rotate, the bevel gear 418 drives another bevel gear 418 to rotate, the other bevel gear 418 drives the bidirectional screw rod 414 to rotate, the bidirectional screw rod 414 drives the two threaded sleeves 415 to slide towards each other along the sliding cavity 413 through the two opposite threads at the same time, the two threaded sleeves 415 drive the clamping plates 416 connected thereto to move towards each other, respectively, until the two clamping plates 416 cooperate to clamp the electric energy meter.

[0057] When the staff needs to connect or separate the electric energy meter and the probe module 300, the staff only needs to manually control the electric cylinder 411 to retract or extend, the electric cylinder 411 drives the mounting plate 412 to descend or ascend, the mounting plate 412 drives the threaded sleeve 415 and the clamping plate 416 to descend or ascend through the sliding cavity 413, at this time, the two clamping plates 416 cooperate to clamp the electric energy meter to descend or ascend, so that the electric energy meter can be stably connected or separated from the probe module 300.

[0058] Working principle: When the staff needs to test the performance of the electric energy meter, the staff only needs to place the corresponding electric energy meter on the top of the first sliding frame 420 and attach it together with the mounting plate 412, the staff can first center the clamping electric energy meter through the centering guide mechanism 410, so that the wiring terminal socket of the electric energy meter is aligned with the probe on the probe module 300, then the electric energy meter is driven to move downward at a constant speed, so that the probe moves towards the electric energy meter and is inserted into the wiring terminal socket of the electric energy meter, then the staff can normally test the performance of the electric energy meter through the electric energy meter tester 200, in this process, the centering guide mechanism 410 not only aligns the wiring terminal socket of the electric energy meter with the probe on the probe module 300, but also drives the electric energy meter to be stably connected with the probe module 300, effectively reducing the probability of bending or deviation of the probe module 300 due to misalignment.

[0059] It should be noted that the above description of the electrical test bench 100, the electric energy meter tester 200, the probe, the wire, the electric cylinder 411, the bidirectional screw rod 414 and the servo motor 417 are all mature devices in existing technology, and the specific model can be selected according to actual needs, and the power supply of the electrical test bench 100, the electric energy meter tester 200, the electric cylinder 411 and the servo motor 417 can be built-in power supply or mains power supply, and the specific power supply mode is selected as needed, which is not described here.
