Description

TECHNICAL FIELD

[0002] With the intelligent development of the power system, the intelligent electric meter as a kind of metering equipment is widely used in residential and commercial power supply scenarios. The intelligent electric meter can not only realize accurate electric energy metering, but also has functions such as remote meter reading, data transmission, fault alarm, etc., thereby improving the management efficiency and operation reliability of the power system. The power-on end of the single-phase intelligent electric meter is usually composed of a cuboid copper block and a screw. A long hole is formed in the middle of the cuboid copper block, and the screw is screwed on the upper part of the cuboid copper block. When connecting electricity, the wire is inserted into the long hole, and then the screw is twisted to move downward to press the wire, thereby realizing stable electrical connection. In actual use, the single-phase intelligent electric meter needs to be disassembled and repaired after being used for four or five years. During the repair, the electric meter is placed on a detection table. The interface end of the detection table is connected with a probe through a wire. The probe is inserted into the electric end hole of the electric meter, thereby realizing the power-on detection of the electric meter. Through this way, the operation of the electric meter, such as electric energy metering accuracy, communication function, fault alarm, etc., can be detected.

[0003] In the process of detecting a large number of electric meters, the detection table is usually equipped with a cylinder-driven probe for inserting into and pulling out the electric end hole of the electric meter to realize the detection of the electric meter. However, the probe is exposed to the external environment for a long time, and dust is easily attached to the end of the probe. When the probe is inserted into the electric end hole, the dust enters along with it, which increases the contact resistance and reduces the stability and accuracy of the detection signal. In addition, in the process of large-scale insertion and pulling out, if the alignment accuracy of the probe and the electric end hole of the electric meter is insufficient, the probe is easy to rub against the hole wall, which causes the surface of the probe to wear out. The worn-out probe may be deformed or have an uneven surface, which affects the contact stability of the probe and the terminal of the electric meter, thereby causing the problem of unstable detection signal or poor contact.

[0004] To solve the above problems, an intelligent electric meter detection device and a detection method thereof are provided in the present application. SUMMARY

[0051] In the embodiment, the tooth condition 7 comprises a rack body 71, the rack body 71 is installed in a vertical posture on the back of the fixed cover 41 and located between the two gears 63, the rack body 71 is connected with the fixed cover 41 through a butt joint rod, the two sides of the rack body 71 are provided with tooth blocks 72, and the tooth blocks 72 on the two sides of the rack body 71 are respectively engaged with the two gears 63; when the electric guide rail 21 drives the fixed cover 41 to move up and down, the rack body 71 moves in the vertical direction synchronously with the fixed cover 41, since the tooth blocks 72 on the two sides of the rack body 71 are respectively engaged with the two gears 63, the movement drives the two gears 63 to rotate at the same time, the rotation of the gear 63 is transmitted to the brush roller 62 through the brush rod 61, so that the two brush rollers 62 rotate at the same time, the above design can clean the probe 101 from both sides, improves the comprehensiveness and efficiency of cleaning, further reduces the dust residue on the surface of the probe 101, and guarantees the contact stability during detection.

[0052] In this embodiment, the elastic insert 5 includes a partition block 51, a guide pipe 52, a hollow shaft 53 and a second spring 54, the partition block 51 is installed in the hollow cover 4 and below the brush roller 62, the guide pipe 52 slides through the middle part of the partition block 51, the hollow shaft 53 is installed at the top end of the guide pipe 52, the second spring 54 is sleeved on the guide pipe 52, and the two ends of the second spring 54 are connected with the partition block 51 and the hollow shaft 53 respectively, a plug-in channel 531 is arranged in the guide pipe 52 and passes through the hollow shaft 53 and is used for the probe 101 to pass through, a sliding opening 401 is arranged on the back of the hollow cover 4, a sliding rod 532 is installed on the hollow shaft 53 and is in sliding cooperation with the sliding opening 401 and below the rack body 71, and a pressure sensor 533 is installed on the sliding rod 532 and is opposite to the rack body 71.

[0054] It should be noted that when the guide pipe 52 moves downward and is not inserted into the electric terminal hole, the force of the rack body 71 pushing the sliding rod 532 to move downward will increase under the action of the electric guide rail 21, and the pressure sensor 533 on the sliding rod 532 can monitor the force of the rack body 71 moving downward, so as to remind the staff that the guide pipe 52 deviates when moving downward;

[0055] In actual application, there is an elastic conductive sheet on the inner wall of the electric terminal hole, if the elastic conductive sheet is deformed in the use process, the probe 101 will be in contact with the elastic conductive sheet when being inserted into the electric terminal hole, and the end of the probe 101 will be bent, therefore, the elastic insert 5 designed in the application can play a detection role, when the guide pipe 52 is inserted into the electric terminal hole, the guide pipe 52 will be in contact with the deformed elastic conductive sheet, at this time, the pressure monitored by the pressure sensor 533 on the sliding rod 532 will change, so as to timely remind the staff that the electric meter has a problem, which not only plays a detection role, but also effectively prevents the probe 101 from being damaged in detection.

[0060] The detection principle is that when the probe 101 is inserted into the bottom of the electric terminal hole of the electric meter and contacts with the electrical terminal inside the electric meter, the interface end 22 sends the detection required electrical signal, such as an analog electrical load signal, to the probe 101 through the wire 23. The signal is transmitted to the internal circuit of the electric meter through the probe 101, and the response signal, such as the metering data and the state feedback signal, generated by the electric meter after receiving the signal is transmitted back to the interface end 22 through the probe 101 and the wire 23. The external detection system connected with the interface end 22 analyzes and processes the received response signal, thereby completing the detection of the performance of the electric meter, such as the electric energy metering accuracy, the communication function and the fault alarm.

[0062] It should be noted that the inner wall of the hollow cover 4 is provided with a dust extraction cavity, and the two ends of the dust extraction cavity are respectively communicated with two dust extraction holes, one of which corresponds to the position of the brush roller 62, and the other is located below the partition block 51. The dust extraction pump 43 is communicated with the dust extraction cavity. When the dust in the electric terminal hole is blown up, the dust extraction pump 43 is started at this time, so that the dust blown up is sucked from the dust extraction hole below the partition block 51, and then discharged through the dust extraction pump 43.

[0063] In this embodiment, the limiting part 3 includes an electric sliding rail 31 and a loading plate 32.

The loading plate 32 is provided with a plurality of limiting parts for fixing the ammeter. Before detection, the ammeter is placed on the limiting part of the loading plate 32 and fixed. The electric sliding rail 31 drives the loading plate 32 to move transversely, and the ammeter is transported one by one to the detection position below the hollow cover 4. After detection, the electric sliding rail 31 drives the loading plate 32 to move away from the detection station, and the next ammeter to be detected is transported.
