These devices can accurately measure the cables and provide detailed test reports to record the test results and status of each cable.

[0003] Power cable alignment detection is an indispensable part of power system construction and maintenance.

[0014] As a further solution of the present invention: a shunt seat is fixedly arranged in the middle of the rear side of the detection seat.

[0015] A method for using the above-mentioned cable alignment instrument for power construction, the steps comprising: S1: The main unit and the auxiliary unit communicate with each other through the metal shielding layer or tensile metal wire in the cable as the neutral line. The main unit performs connection detection on the main ground line, and the auxiliary unit performs connection detection on the auxiliary ground line. S2: Connect multiple cells in the cable to the main detection wiring port respectively, install the label printer at the bottom of the alignment instrument host, and the main single-chip control circuit board in the alignment instrument host detects the number of cells to be detected, and then transmits the signal one by one to the label printer through the first communication contact, prints labels one by one and sticks them on the corresponding cells, and the process is displayed synchronously on the main LCD screen; S3: Move the label printer from the bottom of the alignment instrument host to the bottom of the alignment instrument auxiliary machine, install the backup power supply at the bottom of the alignment instrument host, let the anti-drop device clamp the cable, and place all the battery cells in the cable in the first detection space; S4: The main unit of the alignment instrument provides pulse signals to the cells in the cable one by one in sequence. The operator places multiple cells in the corresponding first detection part. If one of the line-finding indicator lights and the first buzzer gives an alarm, the corresponding cell can be found. If the line-finding indicator light and the first buzzer do not give an alarm, the corresponding cell will continue to be found. If the corresponding cell cannot be found in the remaining cells, the auxiliary unit of the alignment instrument communicates with the main unit of the alignment instrument to detect the next cell. S5: Shift the found corresponding battery cells and place them in the second detection space, and let the first detection space and the second detection space simultaneously detect pulse signals for all battery cells. If only the second detection space detects, only the alarm light on the second detection space side will flash. If the first detection space and the second detection space detect pulse signals at the same time, the second buzzer and the alarm light will sound an alarm, and continue to detect the battery cells in the first detection space one by one in the line-finding device to find the battery cells with pulse signals, and then let the first detection space and the second detection space perform detection again until only the alarm light on the second detection space side flashes, and then the auxiliary single-chip control circuit board in the auxiliary machine of the alignment instrument communicates with the label printer via the second communication contact, and affixes a "short circuit" label to the found battery cell, and places the labeled battery cell in the "unqualified area" in the line-finding device; S6: When there is only one corresponding battery cell, install the battery cell on the auxiliary detection wiring port, and the alignment instrument host communicates with the single-chip computer in the alignment instrument auxiliary machine. If the corresponding main LED indicator on the alignment instrument host is always on, and the corresponding auxiliary LED indicator on the alignment instrument auxiliary machine is always on, the detected battery cell is qualified, and the main LCD screen and the auxiliary LCD screen display the qualified alignment result. If the LED indicators on the alignment instrument host and the alignment instrument auxiliary machine are sometimes on and sometimes off, the state of the detected battery cell is questionable, and the main LCD screen and the auxiliary LCD screen display the questionable alignment result; S7: When the LED indicator is always on, the single-chip computer in the auxiliary machine of the alignment instrument communicates with the label printer via the second communication contact, and affixes a "qualified" label to the tested battery cell, removes the labeled battery cell from the auxiliary detection wiring port, and places it in the "qualified area" in the line-finding device. When the LED indicator is on and off, the single-chip computer in the auxiliary machine of the alignment instrument communicates with the label printer via the second communication contact, and affixes a "doubtful" label to the tested battery cell, removes the labeled battery cell from the auxiliary detection wiring port, and places it in the "doubtful area" in the line-finding device. S8: Repeat the above steps until the entire cable alignment work is completed.

[0016] As a further solution of the present invention: if there are remaining battery cells after the detection is completed, a "broken circuit" label is printed by a label printer and attached to the remaining battery cells, which are then placed in the "unqualified area" in the line-finding device, and the line-finding instrument host records the serial number of the "broken circuit".

[0017] Compared with the prior art, the present invention has the following beneficial effects: The main built-in power supply is used to provide power to the entire device. The fixed bracket separates multiple cells in the cable, which is convenient for connecting the cells in the cable to the main detection wiring port to prevent multiple cells from being entangled. The first communication contact is convenient for communicating with the label printer and the backup power supply. The label printer prints out the label and manually sticks it on the corresponding cell. The backup power supply can temporarily charge the main built-in power supply. The auxiliary built-in power supply provides power to the line-finding device, thereby determining the corresponding cable, making it easier to attach the label to the cable. The anti-drop device compresses the cable to prevent it from falling off during cable measurement. Through multiple first detection parts, multiple cables can be inspected. When the corresponding cable core is detected, the line search indicator light and the first buzzer sound an alarm at the same time, which is convenient for quickly finding the corresponding cable core and improving the efficiency of cable detection. The pressure plate and the shaft baffle cooperate to compress the cable core for the second time to prevent the core from being entangled after detection. The three stepped holes separate and store the cable cores after detection, which are divided into qualified area, unqualified area and doubtful area, which is convenient for subsequent remedial measures for the cable; The fixed upper seat and the fixed lower seat are locked by the buckle, and the threaded control rod is rotated to allow the clamping seat to move in the moving space, so that the clamping seat presses the cable to prevent the cable from falling off, making it easier for the cable-finding device to detect the cable; The battery cell to be tested is shunted through the shunt socket, and the battery cell to be tested is placed in the first detection space. The tested battery cell is placed in the second detection space. After testing one battery cell, the batteries in the first detection space and the second detection space are tested at the same time. When both have pulse signals, the second buzzer and the alarm light alarm together, proving that the battery cells in the cable are cross-entangled (there is a short circuit). The short-circuited battery cell is confirmed by the line-finding device. When only one detection space detects a pulse signal, the second buzzer and the alarm light do not work, thereby achieving the purpose of detecting the short-circuited battery cell and improving the practicality of the line alignment instrument.

This detection method is a prior art). When the battery cell in the corresponding cable is detected, the line-finding indicator light 2402 and the first buzzer 2407 sound an alarm at the same time, which is convenient for quickly finding the battery cell in the corresponding cable and improving the efficiency of cable detection. The pressure plate 2406 and the shaft baffle 2409 cooperate to compress the battery cell in the cable for a second time to prevent the battery cell from being entangled after detection. The three stepped holes 2404 separate and store the battery cells in the cable after detection, which are divided into qualified area, unqualified area and doubtful area, which is convenient for subsequent remedial measures for the cable (the line-finding principle has been disclosed in the invention patent of a line-finding device and its line-finding method, host and slave with authorization announcement number CN113740777B, and no relevant explanation is given).

[0033] The anti-slip device 25 includes a fixed lower seat 251 and a first protrusion 258. The fixed lower seat 251 is slidably installed in the first card slot 2410 through the first protrusion 258. A fixed upper seat 253 is rotatably installed above the fixed lower seat 251 through a hinge. A buckle 252 is provided on the left side of the fixed upper seat 253 and the fixed lower seat 251. A moving space 254 is opened inside the fixed upper seat 253 and the fixed lower seat 251. A clamping seat is slidably provided in the moving space 254 and is located in the fixed upper seat 253. 255, a threaded hole is opened on the clamping seat 255, and a threaded control rod 257 is installed in the threaded hole. One side of the threaded control rod 257 is located at the clamping seat 255 and fixed with a limited end 256. The fixed upper seat 253 and the fixed lower seat 251 are locked by the buckle 252. The threaded control rod 257 is rotated to allow the clamping seat 255 to move in the moving space 254, so that the clamping seat 255 can press the cable to prevent the cable from falling off, which is convenient for the line-finding device 24 to detect the cable.

[0034] When the device is used, one end of the cable to be detected is cut open, and the shielding layer in the cable is used as the neutral wire to connect to the main neutral wire connection port 12 in the alignment instrument host 100, and the ground wire is connected to the main ground wire connection port 13, and then multiple cells in the cable are connected to the corresponding main detection connection ports 15, and multiple cells are respectively installed on the fixed brackets 14, and the label printer 300 is installed at the bottom of the alignment instrument host 100, and the alignment instrument host 100 is started to detect the number of multiple cells. The main LED indicator 16 of the corresponding connection port flashes, and the main LCD screen 18 displays the number of detected cells, and the alignment instrument host 100 and the label printer 300 communicate, and gradually print labels one by one and stick the labels on the corresponding cells. After all the cell cable labels are affixed, Replace the label printer 300 with the backup power supply 400. The backup power supply 400 can continue to supply power to the alignment instrument host 100 when the main built-in power supply 17 is out of power (the main built-in power supply 17 is the main power supply for the two alignment instruments and consumes a lot of power). Then place the other end of the cable in the anti-slip device 25, connect the fixed lower seat 251 and the fixed upper seat 253 through the buckle 252, and then turn the threaded control rod 257 to move the clamping seat 255 in the moving space 254, so that the clamping seat 255 can compress the cable. Then install the label printer 300 at the bottom of the alignment instrument auxiliary machine 200, let the alignment instrument auxiliary machine 200 communicate with the label printer 300, cut the other end of the cable to be tested, and use the shielding layer in the cable as The neutral line is connected to the auxiliary neutral line connection port 22 in the alignment instrument auxiliary machine 200, and the ground line is connected to the auxiliary ground line connection port 23. The alignment instrument host 100 reflects the electromagnetic pulse signal to the battery cells one by one in sequence, and then multiple battery cells are placed in the corresponding first detection unit 2403. When the first detection unit 2403 detects the pulse signal, the line search indicator light 2402 flashes and the first buzzer 2407 generates a sound prompt. The corresponding battery cell after determination is taken out and connected to one of the auxiliary detection connection ports 20. The single-chip control circuit board in the alignment instrument host 100 and the alignment instrument auxiliary machine 200 forms a loop, and the corresponding main LED indicator light 16 and the auxiliary LED indicator light 26 are always on, and the main LCD screen 18 and the auxiliary LCD screen 28 display the confirmation that the battery cells are connected (in the authorized public The principle of line connection and disconnection is disclosed in a network cable alignment device with notification number CN209088979U, which will not be explained here). At the same time, the signal is also transmitted to the label printer 300. The label printer 300 prints out a label identical to the corresponding battery cell on the alignment instrument host 100, and then sticks the label on the corresponding battery cell. Then the corresponding battery cell is removed and placed in the qualified area of ​​the three stepped holes 2404 through the rotating shaft baffle 2409. When the first detection unit 2403 still cannot detect the corresponding battery cell, it can be determined that the detection battery cell is broken, and then the alignment instrument host 100 performs the next battery cell detection (a variety of means can be used to achieve this purpose, such as using the neutral line and the confirmed battery cell to allow the alignment instrument host 100 and the alignment instrument auxiliary machine 200 to communicate;Or the main unit 100 of the alignment instrument sets a certain detection time, and when the time comes, the next battery cell is detected, etc.), after all the battery cells are detected, the remaining battery cells are placed in the unqualified area of ​​the three stepped holes 2404; when the detection effect of the first detection unit 2403 is poor, the line search indicator 2402 flashes from time to time, and the first buzzer 2407 sounds from time to time, the battery cell is taken out and connected to one of the auxiliary detection connection ports 20. If the main unit 100 of the alignment instrument and the auxiliary unit 200 of the alignment instrument cannot communicate stably, the battery cell is placed in the doubtful area of ​​the three stepped holes 2404, and the above operation is repeated to complete the detection of the cable battery cells. ;

[0035] Example 2: Please refer to Figure 7-Figure 8 On the basis of Example 1, a cross detection device 30 is arranged between the line-finding device 24 and the anti-slip device 25, and the cross detection device 30 includes a detection seat 301 and a second protrusion 308. The detection seat 301 is slidably installed in the first card slot 2410 through the second protrusion 308. Second buzzers 302 are arranged on both sides of the detection seat 301, and an alarm light 303 is arranged in the detection seat 301 above the second buzzer 302. A second card slot 304 cooperating with the first protrusion 258 is opened in the detection seat 301 behind the alarm light 303. A shunt seat 305 is fixedly arranged in the middle of the rear side of the detection seat 301. A first detection space 306 is opened on the detection seat 301, and one side of the first detection space 306 is located at the detection seat 301. A second detection space 307 is opened on the top, and the battery cell to be detected is shunted through the shunt seat 305. The battery cell to be detected is placed in the first detection space 306, and the detected battery cell is placed in the second detection space 307. After detecting one battery cell, the batteries in the first detection space 306 and the second detection space 307 are detected at the same time. When there are pulse signals in both, the second buzzer 302 and the alarm light 303 sound an alarm together, proving that the battery cells in the cable are cross-entangled (there is a short circuit). The line-finding device 24 confirms and finds out the short-circuited battery cell. When only one detection space detects a pulse signal change, the second buzzer 302 and the alarm light 303 do not work, thereby achieving the purpose of detecting the short-circuited battery cell and improving the practicality of the line alignment instrument.

[0036] When in use, the anti-drop device 25 clamps the cable, the shunt seat 305 shunts the battery to be detected, and the line-finding device 24 detects the battery. After finding the corresponding battery, the first detection space 306 and the second detection space 307 detect the battery. If the second buzzer 302 and the alarm light 303 do not alarm, the corresponding battery is taken out and connected to one of the auxiliary detection wiring ports 20, and the corresponding auxiliary LED indicator 26 is always on, and then the main unit 100 and the auxiliary unit 200 of the alignment instrument are checked. The signal handshake, the main LCD screen 18 and the sub-LCD screen 28 display confirmation that the battery cells are connected, and also transmit the signal to the label printer 300. The label printer 300 prints out the same label as the corresponding battery cell on the alignment instrument host 100, and then sticks the label on the corresponding battery cell; when the second buzzer 302 and the alarm light 303 sound together, it proves that the battery cells in the cable are crossed, and the short-circuited battery cell is found through the line-finding device 24, and then the short-circuited battery cell is placed in the unqualified area among the three stepped holes 2404.

[0037] See also Figure 7-Figure 9 , a method for using a cable alignment instrument for electric power construction, the steps comprising: S1: The alignment instrument host 100 and the alignment instrument slave 200 communicate signals through the metal shielding layer or the tensile metal wire in the cable as the neutral wire. The alignment instrument host 100 performs connection detection on the main ground wire, and the alignment instrument slave 200 performs connection detection on the slave ground wire. S2: Connect multiple cells in the cable to the main detection connection port 15 respectively, install the label printer 300 at the bottom of the alignment instrument host 100, and the main single-chip control circuit board in the alignment instrument host 100 detects the number of cells to be detected, and then transmits the signal one by one to the label printer 300 through the first communication contact 19, prints labels one by one and sticks them on the corresponding cells, and the process is synchronously displayed on the main LCD screen 18; S3: Move the label printer 300 from the bottom of the alignment instrument main unit 100 to the bottom of the alignment instrument auxiliary unit 200, install the backup power supply 400 at the bottom of the alignment instrument main unit 100, let the anti-drop device 25 clamp the cable, and place all the battery cells in the cable in the first detection space 306; S4: the alignment instrument host 100 provides pulse signals to the battery cells in the cable one by one in sequence, and the operator places multiple battery cells in the corresponding first detection part 2403. If one of the line-finding indicator lights 2402 and the first buzzer 2407 gives an alarm, the corresponding battery cell can be found. If the line-finding indicator light 2402 and the first buzzer 2407 do not give an alarm, the corresponding battery cell will continue to be searched. If the corresponding battery cell cannot be found in the remaining battery cells, the alignment instrument auxiliary machine 200 communicates with the alignment instrument host 100 to detect the next battery cell. S5: The corresponding battery cells are shifted and placed in the second detection space 307, and the first detection space 306 and the second detection space 307 are allowed to perform pulse signal detection on all the battery cells at the same time. If only the second detection space 307 detects, only the alarm light 303 on the second detection space 307 side flashes. If the first detection space 306 and the second detection space 307 detect pulse signals at the same time, the second buzzer 302 and the alarm light 303 sound an alarm, and the battery cells in the first detection space 306 are continuously detected one by one in the line-finding device 24 to find the battery cells with pulse signals, and then the first detection space 306 and the second detection space 307 are detected again until only the alarm light 303 on the second detection space 307 side flashes, and then the auxiliary single-chip control circuit board in the auxiliary machine 200 of the alignment instrument communicates with the label printer 300 via the second communication contact 29, and affixes a "short circuit" label to the found battery cell, and places the labeled battery cell in the "unqualified area" in the line-finding device 24; S6: When there is only one corresponding battery cell, install the battery cell on the auxiliary detection connection port 20, and the alignment instrument host 100 communicates with the single-chip microcomputer in the alignment instrument auxiliary machine 200. If the corresponding main LED indicator 16 on the alignment instrument host 100 is always on, and the corresponding auxiliary LED indicator 26 on the alignment instrument auxiliary machine 200 is always on, the detected battery cell is qualified, and the main LCD screen 18 and the auxiliary LCD screen 28 display the qualified alignment result. If the LED indicators on the alignment instrument host 100 and the alignment instrument auxiliary machine 200 are sometimes on and sometimes off, the state of the detected battery cell is questionable, and the main LCD screen 18 and the auxiliary LCD screen 28 display the questionable alignment result; S7: When the LED indicator light is always on, the single-chip microcomputer in the auxiliary machine 200 of the alignment instrument communicates with the label printer 300 via the second communication contact 29, and affixes a "qualified" label to the detected battery cell, removes the labeled battery cell from the auxiliary detection wiring port 20, and places it in the "qualified area" in the line-finding device 24. When the LED indicator light is on and off, the single-chip microcomputer in the auxiliary machine 200 of the alignment instrument communicates with the label printer 300 via the second communication contact 29, and affixes a "questionable" label to the detected battery cell, removes the labeled battery cell from the auxiliary detection wiring port 20, and places it in the "questionable area" in the line-finding device 24. S8: Repeat the above steps until the entire cable alignment work is completed; S9: If there are remaining cells after the test is completed, a "broken circuit" label is printed by the label printer 300 and attached to the remaining cells, and then placed in the "unqualified area" in the line-finding device 24, and the alignment instrument host 100 records the serial number of the "broken circuit".
