Description

Technical Field

[0002] A smart meter is one of the basic devices for data collection in a smart grid (especially a smart distribution network), undertaking the tasks of collecting, measuring, and transmitting original electrical energy data, and is the basis for realizing information integration, analysis and optimization, and information display. In addition to the basic power consumption measurement function of a traditional electricity meter, in order to adapt to the smart grid and the use of new energy, a smart meter also has intelligent functions such as two-way multi-rate metering function, user-side control function, two-way data communication function with multiple data transmission modes, and anti-stealing electricity function.

[0003] The power-on end of a single-phase smart meter consists of a cuboid copper block and a screw. A long hole is provided 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 turned to move downward to press the wire tightly. After the single-phase smart meter has been running for four or five years, it needs to be disassembled for maintenance. The existing automatic inspection device directly powers on and detects the single-phase smart meter after simple positioning. However, dust will remain in the small holes at the power-on end of the smart meter after long-term use, and the dust forms a film covering the inner wall of the small holes in the copper block, resulting in poor contact during the detection process and abnormal various detection data.

[0042] During the preparation work, fix the two fixing brackets 2 on the workbench to keep the intelligent electric meter detection device for maintenance stable. Connect an external vacuum cleaner to the pipeline 504, turn on the power supply, and operate the external controller to control the device to start working. Manually place the intelligent electric meter to be detected directly above the first linkage plate 204, with the power supply end of the intelligent electric meter on the right side. Then, manually drive the intelligent electric meter downward so that the intelligent electric meter contacts the inclined surface on the upper side of the second side plate 206. Manually push the intelligent electric meter downward so that the intelligent electric meter pushes the second side plate 206 backward. The second side plate 206 stretches the two first springs 301. At the same time, the second side plate 206 drives the first limit rod 302 backward, the first limit rod 302 drives the first rack 303 backward, the first rack 303 drives the spur gear 305 to rotate, the spur gear 305 drives the transmission rod 304 to rotate, the spur gear 305 drives the second rack 307 to drive the second limit rod 306 forward, and the second limit rod 306 drives the first side plate 205 forward, so that the first side plate 205 and the second side plate 206 move away from each other, and the moving distances of the first side plate 205 and the second side plate 206 are the same. When the lower side of the intelligent electric meter contacts the first linkage plate 204, manually push the intelligent electric meter to the left so that the left side of the intelligent electric meter is flush with the bent part on the left side of the first linkage plate 204. Then, manually stop contacting the intelligent electric meter. Under the action of the two first springs 301, the first side plate 205 and the second side plate 206 clamp the intelligent electric meter. During this process, the moving distances of the first side plate 205 and the second side plate 206 are always equal, so as to position the intelligent electric meter to the specified position. Then, the first telescopic cylinder 401 drives the second linkage 402 to move to the left, and the second linkage 402 drives the parts associated with it to move to the left, so that the first positioning post 404 is inserted into the positioning hole of the intelligent electric meter. The second linkage 402 continues to move to the left, so that the first elastic telescopic rod 403 moves to the left, so that the left telescopic end of the first elastic telescopic rod 403 contracts. Then, the second linkage 402 drives the dust cleaning pipe 501 to move to the left and insert it into the small hole of the copper block at the power supply end of the intelligent electric meter. When disassembling the intelligent electric meter, some screws are not completely screwed out of the small hole of the copper block, that is, the lower end of the screw is still in the small hole of the copper block, so that the dust cleaning pipe 501 moves to the left and contacts the screw in the small hole. When the second linkage 402 continues to move to the left, the dust cleaning pipe 501 is blocked and limited by the screw and cannot move forward. At this time, the second linkage 402 drives the pressure sensor 405 to move to the left, and at the same time stretches the second spring 502, so that the pressure sensor 405 contacts the contact block 503, and the pressure sensor 405 sends out an obstacle signal. Then, the first telescopic cylinder 401 drives the second linkage 402 to move back to the original position, and the second linkage 402 drives the parts associated with it to move back to the original position. According to the obstacle signal, the second electric slider 602 slides on the second guide rail 601, the second electric slider 602 drives the second electric push rod 603 to move, and the second electric push rod 603 drives the third linkage 604 to move.The third linkage 604 drives the electric screwdriver 605 to move, causing the electric screwdriver 605 to move above the small hole screw of the copper block that has not been fully unscrewed. Then, the second electric push rod 603 drives the third linkage 604 to move downward, and the third linkage 604 drives the electric screwdriver 605 to move downward, so that the lower end of the electric screwdriver 605 is inserted into the screw. Start the electric screwdriver 605, and the electric screwdriver 605 screws the screw upward, causing the lower end of the screw to disengage from the small hole in the middle of the copper block. At this time, the screw is still screwed to the upper part of the copper block. Turn off the electric screwdriver 605, and the second electric push rod 603 drives the third linkage 604 to drive the electric screwdriver 605 to move upward back to the original position. Then, the first telescopic cylinder 401 drives the second linkage 402 to move leftward, so that the dust cleaning pipe 501 is inserted to the bottom of the small hole of the copper block. Then, the first electric push rod 505 drives the limit post 506 to move, and the limit post 506 drives the two third limit rods 508 and the two fourth limit rods 5011 to move centrifugally. The two third limit rods 508 drive the two first scraping plates 509 to move respectively, and the two fourth limit rods 5011 drive the two second scraping plates 5012 to move respectively, while compressing the two third springs 5010 and the two fourth springs 5013, so that after the two first scraping plates 509 and the two second scraping plates 5012 move centrifugally, they are both in contact with the inner wall of the copper block hole. Then, the first telescopic cylinder 401 drives the second linkage 402 to move rightward back to the original position, causing the dust cleaning pipe 501 to drive the parts associated with it to move rightward, so that the two first scraping plates 509 and the two second scraping plates 5012 move rightward along the copper block hole wall, thereby scraping off the dust covering the copper block hole wall. The scraped dust overflows into the two annular grooves on the left of the dust cleaning pipe 501. Then, the external vacuum cleaner starts to suck air, so that the dust moves through the through holes on the annular groove to the inner wall of the dust cleaning pipe 501, and then flows out through the dust cleaning pipe 501 and the pipe 504. The external vacuum cleaner stops sucking air, and the first electric push rod 505 drives the limit post 506 to move rightward, so that the two third springs 5010 drive the two third limit rods 508 to move back to the original position, and the two fourth springs 5013 drive the two fourth limit rods 5011 to move back to the original position. Then, the first electric slider 202 moves backward on the first guide rail 201, and the first electric slider 202 drives the first linkage 203 to move backward, and the first linkage 203 drives the parts associated with it to move backward, thereby driving the smart meter to move to the left of the detection component. Then, the second telescopic cylinder 801 drives the detection head 802 to move leftward, and the detection head 802 drives the parts associated with it to move leftward, so that the second positioning post 804 is inserted into the positioning hole of the smart meter. When the second positioning post 804 moves to the deepest position, the smart meter blocks the limit block for the second positioning post 804, and the detection head 802 continues to move leftward, thereby compressing the second elastic telescopic rod 803. Then, the detection head 802 drives the three power-on terminals 805 to be inserted into the three power-on terminal copper block holes on the smart meter.The three power-on terminals 805 are in full contact with the three power-on terminal copper block holes on the smart meter. The detection head 802 drives the three signal terminals 806 to be inserted into the three signal terminal holes on the smart meter, and then the detection head 802 detects the corresponding functions of the smart meter. When in use, it realizes automatically cleaning the dust on the hole wall of the power-on terminal copper block of the smart meter, and then detecting the corresponding functions of the smart meter, avoiding the phenomenon of poor contact, greatly improving the correctness of the detection result. At the same time of dust cleaning, it automatically screws up the too-low screws on the power-on terminal copper block, avoiding the phenomenon that the detection contact head cannot be inserted into the power-on terminal copper block hole of the smart meter, and greatly improving the efficiency.

[0043] Embodiment 2

[0044] Based on Embodiment 1, as Figure 1 and Figures 11-12 shown, it further includes an adjustment component. The adjustment component is installed at the rear of the fixing component. The adjustment component includes a fourth linkage frame 701, a third guide rail 702, a third electric slider 703, a second linkage plate 704, a third electric push rod 705, a pressing plate 706, a fourth electric push rod 707 and a pushing frame 708; the fourth linkage frame 701 is welded to the rear side of the first linkage plate 204; the upper part of the front side of the fourth linkage frame 701 is fixedly connected with the third guide rail 702; the third guide rail 702 is slidably connected with the third electric slider 703; the third electric slider 703 is fixedly connected with the second linkage plate 704 at the front side; the second linkage plate 704 is fixedly connected with the third electric push rod 705 at the front side; the front telescopic end of the third electric push rod 705 is fixedly connected with the pressing plate 706; the fourth electric push rod 707 is fixedly connected to the lower rear part of the first linkage plate 204; the lower telescopic end of the fourth electric push rod 707 is fixedly connected with the pushing frame 708.

[0045] When the smart meter moves to the left of the detection component, the second telescopic cylinder 801 drives the detection head 802 to move leftward. The detection head 802 drives the parts associated with it to move leftward, so that the second positioning post 804 is inserted into the positioning hole of the smart meter. Since the smart meter has been used for a long time, the outer shell is deformed. At this time, the rear side of the smart meter will tilt upward or downward. When the rear side of the smart meter tilts upward, the third electric push rod 705 drives the pressing plate 706 to move forward to the rear upper part of the smart meter. Then, the third electric slider 703 slides downward on the third guide rail 702. The third electric slider 703 drives the second linkage plate 704 to move downward. The second linkage plate 704 drives the third electric push rod 705 to move downward. The third electric push rod 705 drives the pressing plate 706 to move downward, so that the pressing plate 706 presses the rear side of the smart meter downward, thus making the smart meter in a horizontal state. When the rear side of the smart meter tilts downward, the fourth electric push rod 707 drives the pushing frame 708 to move upward, so that the pushing frame 708 pushes the rear side of the smart meter to move upward, thus making the smart meter in a horizontal state. During use, the smart meter with a deformed outer shell is automatically positioned in a horizontal state, avoiding the phenomenon that the detection contact cannot be inserted into the smart meter.

[0046] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
