TECHNICAL FIELD
[0001] The present application relates to the technical field of circuit household detection, in particular to a kind of electric line circuit household detection device and method. BACKGROUND
[0002] In the power system of residential and commercial buildings, due to non-standard construction, line aging or human private connection, etc., the phenomenon of household connection between different user circuits often occurs (i.e. the electric line of a certain household is incorrectly connected to another household's electric meter or power supply circuit). Household connection not only leads to incorrect electricity metering, but also may cause safety hazards (such as overload, short circuit, etc.). Currently, in the process of household connection detection for new low-voltage electric meters, the traditional manual detection method is still used. The traditional detection method has many limitations and cannot meet the efficient and accurate detection requirements. The main performance is as follows: 1. Long time consumption with manual assistance: Currently, household connection detection usually relies on manual operation, which requires two workers to work together: one uses a robot in the house to create a load, and the other observes the current change of the corresponding electric meter near the electric meter box to determine whether there is a household connection problem. If the electric meter shows a current change, it means that the electric meter is normal and there is no household connection. If there is no current change, it may indicate a household connection problem. This method is tedious, time-consuming, and greatly affected by human factors, which can easily lead to misjudgment due to observation errors or external factors, making it difficult to achieve accurate, efficient and standardized batch detection. 2. Poor load adaptability: During detection, a load needs to be connected to simulate actual power consumption, but fixed loads cannot adapt to the current differences of different circuits, which can easily lead to detection errors or equipment damage. 3. High error rate in parallel detection affecting efficiency: When multiple households are detected simultaneously, the existing method does not support parallel operation, which significantly increases the error rate and makes it difficult to accurately identify household connection problems. This not only increases the difficulty of troubleshooting, but also requires repeated verification, which seriously affects the overall detection efficiency. Therefore, we propose a kind of electric line circuit household detection device and method. SUMMARY

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention enables automated load connection testing of different circuits by setting load components and drive components.

[0013] 2. By setting up a drive component, the present invention can realize multi-functional drive operation.

[0015] 4. By setting up a load component, the present invention can perform load adjustment operation. Specifically, the threaded engagement design between the load cylinder and the second contact frame, combined with the rotation adjustment of the first drive shaft, can dynamically change the contact position of the second contact frame on the load cylinder, thereby adjusting the load resistance value of the connected circuit, adapting to circuits with different current intensities, avoiding detection errors or equipment damage due to excessive load, and ensuring the accuracy of the detection results.

[0022] The load component 2 can automatically connect different user circuits and adjust the load size according to the circuit current to avoid excessive current running through the load and excessive load affecting detection. like Figures 4 to 9As shown, the load assembly 2 includes a first movable frame 21 and a second movable frame 22 mirror-displayed inside the mounting cavity 14, with the first movable frame 21 and the second movable frame 22 rotatably mounted inside the mounting frame 15. The first movable frame 21 and the second movable frame 22 are circular ring blocks with an "L"-shaped cross-section. A load cylinder 23 is fixedly installed between the first movable frame 21 and the second movable frame 22. The load cylinder 23 is a hollow cylindrical load resistor. A first contact frame 231 is fixedly sleeved on the side of the load cylinder 23, and the first contact frame 231 is attached to the side of the first movable frame 21. The first contact frame 231 is a circular ring block and makes electrical contact with the coil on the side of the load cylinder 23. A second contact frame 232 is movably sleeved on the side of the load cylinder 23.

The first drive shaft 233 is a cylindrical rod with a continuous cross-shaped cross section and a thread in the middle section. A first gear 234 is fixedly mounted on the side of the first drive shaft 233 and is movably positioned inside the mounting frame 15. The first gear 234 is a circular gear. Specifically, the first gear 234 can be driven by subsequent components, causing the first gear 234 to drive the first drive shaft 233 to rotate. The first drive shaft 233 is threadedly engaged with the second contact frame 232, allowing the second contact frame 232 to move on the side of the load cylinder 23. In addition, when the second movable frame 22 is driven, the first movable frame 21, the second movable frame 22, and the load cylinder 23 can rotate synchronously inside the mounting cavity 14. A constraint rod 24 is fixedly installed on the side of the first contact frame 231 and the second contact frame 232 at a position away from the first drive shaft 233. The constraint rod 24 is a T-shaped round rod made of conductive material. A first mating block 241 is movably sleeved on the side of the constraint rod 24 at the position of the first drive shaft 233, and the constraint rod 24 is in contact with the inner side of the first mating block 241. The first mating block 241 is a T-shaped block made of conductive material. A second mating block 242 is movably sleeved on the side of the constraint rod 24 at the position of the first contact frame 231, and the constraint rod 24 is in contact with the inner side of the first mating block 241. Rod 24 fits against the inner side of the second mating block 242, which is a rectangular block made of conductive material. A groove 25, rectangular in shape, is provided on the side of the first movable frame 21 corresponding to the position of the second mating block 242. A slider 251, cylindrical in shape, is movably installed inside the groove 25 and fixedly mounted on the side of the second mating block 242. A movable cavity 26, convex in shape, is provided on the side of the second movable frame 22 corresponding to the position of the first mating block 241. The internal 6 is symmetrically equipped with a second gear 261 and a third gear 262, both of which are circular gears. A synchronous belt 263 is meshed with the sides of the second gear 261 and the third gear 262, and the synchronous belt 263 is movably positioned inside the movable cavity 26. The synchronous belt 263 is an "O"-shaped belt with teeth on the inside. A connecting shaft 264 is fixedly installed on the side of the third gear 262, and the connecting shaft 264 extends through the second movable frame 22 and is flush with the first drive shaft 233. 64 is a cylindrical rod. A fourth gear 265 is fixedly installed on the side of the connecting shaft 264 and is movably positioned inside the mounting bracket 15. The fourth gear 265 is a circular gear. A second mating rod 28 is fixedly connected between the synchronous belt 263 and the side of the first mating block 241. The second mating rod 28 is an adaptively telescopic "L"-shaped telescopic rod. A first mating rod 27 is fixedly connected between the sides of the first mating block 241 and the second mating block 242. The first mating rod 27 is an adaptively telescopic cylindrical telescopic rod.Specifically, the fourth gear 265 is driven by subsequent components, which in turn drives the connecting shaft 264 and the synchronous belt 263 to rotate the third gear 262. The synchronous belt 263 is supported by the second gear 261 and the third gear 262, allowing it to rotate. The synchronous belt 263 then drives the first mating block 241 to slide on the side of the constraint rod 24 via the second mating rod 28. Simultaneously, the first mating rod 27 also drives the second mating block 242 to slide on the corresponding side of the constraint rod 24. The slider 251 slides within the groove 25, constraining the second mating block 242. This allows the first and second mating blocks 241 and 242 to press and contact the side of the circuit breaker block on the constraint block 17. The load circuit is connected via the constraint block 17, the second mating block 242, the first contact frame 231, the load cylinder 23, the first drive shaft 233, the first mating block 241, and the wire 16. At this point, the wire 16 between the constraint blocks 17 is triggered and disconnected. After the load passes through, the current detection of this circuit can determine whether there is cross-connection.
[0023] By setting the driving component 3, the load component 2 can be driven in different states, thereby realizing the operation of the complex detection circuit. like Figure 4 , Figure 5 and Figures 7 to 10As shown, the drive assembly 3 includes a motor 31 fixedly installed inside the mounting bracket 15 corresponding to the first movable frame 21. The motor 31 is a micro motor. A second drive shaft 32 is fixedly installed at the output end of the motor 31 and extends through the interior of the first movable frame 21 and the second movable frame 22 to the inner side of another set of mounting brackets 15. The second drive shaft 32 is flush with the first gear 234 and the fourth gear 265. The second drive shaft 32 is a cylindrical rod with a gear-shaped cross-section. A constraint frame 33 is fixedly installed inside the mounting bracket 15 corresponding to the second movable frame 22. The constraint frame 33 is a circular ring frame with a "C"-shaped cross-section. A mating frame 34 is rotatably installed inside the constraint frame 33. The mating frame 34 is a circular ring frame. A first electric actuator 341 and a second electric actuator 342 are symmetrically and fixedly installed through the side of the mounting bracket 34, with the first electric actuator 341 and the second electric actuator 342 corresponding to the positions between the second drive shaft 32 and the first gear 234 and the fourth gear 265. A fifth gear 343 and a sixth gear 344 are rotatably installed at the output ends of the first electric actuator 341 and the second electric actuator 342, respectively. The fifth gear 343 and the sixth gear 344 are circular gears. A connecting bracket 35 is fixedly installed on the inner side of the mounting bracket 15, with the connecting bracket 35 corresponding to the side position of the mounting bracket 34. The connecting bracket 35 is a snowflake-shaped ring bracket. A third electric actuator 351 is fixedly set at the center position of the connecting bracket 35, and the third electric actuator 351 is in default position. The output end is pressed against the side of the mating frame 34; specifically, by default, the third electric push rod 351 presses against the side of the mating frame 34, fixing the mating frame 34 in a fixed position inside the constraint frame 33. At this time, the first electric push rod 341 pushes the fifth gear 343 to a position between the second drive shaft 32 and the first gear 234 to mesh with it. When the motor 31 drives the second drive shaft 32 to rotate, it can engage with the fifth gear 343 to drive the first gear 234. At this time, the first gear 234 drives the first drive shaft 233 to rotate and mesh with the second contact frame 232, allowing the second contact frame 232 to move and adjust its position on the side of the load cylinder 23. The first mating rod 27 and the second mating rod 28 can move synchronously. The adaptive telescopic operation allows for load size adjustment; similarly, the second electric actuator 342 pushes the sixth gear 344 to a position between the second drive shaft 32 and the fourth gear 265 to mesh with it. At this time, the engagement of the sixth gear 344 drives the fourth gear 265, and the synchronous rotation of the connecting shaft 264 drives the third gear 262 to rotate. The synchronous belt 263 rotates under the drive of the second gear 261 and the third gear 262. The synchronous belt 263 moves the first mating block 241 and the second mating block 242 to contact the constraint block 17 circuit breaker block on the side of the corresponding wire 16 through the second mating rod 28 and the first mating rod 27, thus enabling automated load connection of the circuit.Additionally, the first electric actuator 341 and the second electric actuator 342 continue to push the fifth gear 343 and the sixth gear 344, disengaging them from the meshing of the first gear 234 and the fourth gear 265. This ensures that the fifth gear 343 and the sixth gear 344 remain engaged with the side of the second drive shaft 32 and the side of the second movable frame 22. At this time, the output end of the third electric actuator 351 disengages from the side of the mating frame 34. The motor 31 then drives the second drive shaft 32 to rotate, thus constraining and driving the mating frame 34 to rotate within the constraint frame 33. Simultaneously, the second movable frame 22 rotates due to friction. The entire assembly consisting of the first movable frame 21, the second movable frame 22, and the load cylinder 23 rotates within the mounting cavity 14, causing the first mating block 241 and the second mating block 242 to rotate corresponding to the sides of the wires 16 at different positions.
[0024] Working principle: When using load detection: First, select the corresponding circuit position. Based on the selection, it is known which household circuit needs to be detected. At this time, the first electric push rod 341 and the second electric push rod 342 push the fifth gear 343 and the sixth gear 344 to mesh with the second drive shaft 32. After the first gear 234 and the fourth gear 265 are in contact with the side of the second movable frame 22, the third electric push rod 351 disengages from the side of the mating frame 34. When the motor 31 drives the second drive shaft 32 to rotate, the fifth gear 343 and the sixth gear 344 are constrained and drive the mating frame 34 to rotate inside the constraint frame 33. This causes the first movable frame 21, the second movable frame 22 and the load cylinder 23 to rotate inside the mounting cavity 14 and stop the first mating block 241 and the second mating block 242 at the side of the wire 16 to be detected. Then, the third electric push rod 351 presses against the side of the mating frame 34 to fix it. The first electric push rod 341 and the second electric push rod 342 pull the fifth gear 343 and the sixth gear 344 to reset. The second step is to adjust the load according to the circuit current. Based on the current of the circuit being checked, determine the required load for testing. At this time, the first electric push rod 341 pushes the fifth gear 343 to a position between the second drive shaft 32 and the first gear 234 and meshes with it. When the motor 31 drives the second drive shaft 32 to rotate, it cooperates with the fifth gear 343 to drive the first gear 234 to rotate. Subsequently, the first drive shaft 233 rotates synchronously and meshes with the second contact frame 232. The second contact frame 232 can then move to a position on the side of the load cylinder 23. The first mating block 241 moves accordingly. Different loads can then be connected to the circuit. Afterward, the fifth gear 343 is pulled back to its original position. Third, and finally, the automatic load connection circuit detection is performed. At this time, the second electric actuator 342 pushes the sixth gear 344 to a position between the second drive shaft 32 and the fourth gear 265 and engages with it. When the motor 31 drives the second drive shaft 32 to rotate, it engages with the sixth gear 344 to drive the fourth gear 265 to rotate. The fourth gear 265 drives the third gear 262 to rotate through the connecting shaft 264. The timing belt 263 can then rotate supported by the second gear 261 and the third gear 262. The second engaging rod 28 moves with the timing belt 263 and works in conjunction with the first engaging rod 27 to link the first... The first mating block 241 and the second mating block 242 can slide and contact the side of the constraint rod 24 on the side of the circuit breaker block of the constraint block 17. At this time, the circuit is connected by the constraint block 17, the first mating block 241, the second mating block 242, the constraint rod 24, the first contact frame 231, the second contact frame 232 and the load cylinder 23, so that the corresponding wire 16 can be connected to the load. The wire 16 between the constraint blocks 17 remains disconnected. Then the sixth gear 344 is pulled and reset, and the circuit current after the load is connected is detected to determine whether there is cross-connection.
[0025] A method for using a power line interconnection detection device, such as... Figure 11 As shown, it includes the following steps: Step 1: Start by selecting current reading via the APP. Specifically, the detector establishes a connection with the target meter via HPLC carrier communication based on the communication address sent by the mobile APP, and reads the current current value I0. I0 = I meter initial value, which is used as the reference current for subsequent comparisons. Step 2: Select the corresponding line to automatically control the load connection. Specifically, after clicking "Start Detection" on the mobile APP, the internal load module of the troubleshooter will start and apply the known rated load current IL to the circuit. Step 3: Adjust the usage according to the circuit current and load value; Step 4: Measure the circuit current after the load and calculate the true load current. Specifically, the troubleshooter reads the current value I1 of the meter again through HPLC and calculates the true load current: Itrue = I1 - I0. Step 4.1: If the actual load current measured by the meter is approximately equal to the load current applied by the troubleshooter, it is determined that there is no cross-connection. Specifically, if the actual load current Iactual measured by the meter is approximately equal to the load current IL applied by the troubleshooter, that is, if Iactual - IL ≤ E, where E is the system's allowable error threshold, then it is determined that there is no cross-connection. Step 4.2: If the actual load current measured by the meter differs significantly from the load current applied by the troubleshooter, cross-connection is suspected. Specifically, if there is a large deviation between the two: Iactual - IL > E, it indicates that cross-connection exists, meaning that the current measured by the meter is affected by other lines or users. Step 4.3: Unable to obtain current value, indicating communication failure between the troubleshooter and the electricity meter; Step 4.4: Display a "Communication Failure" or "Interference" message and alert the user on the device panel; Step 5: The detector communicates with the mobile APP via Bluetooth to transmit and store data. Specifically, the detection results are transmitted back to the mobile APP to ensure data traceability and store the following key data: initial current I0, meter number IDMETER, current after load I1 and applied load current IL, and the determination result (cross-connection / no cross-connection / communication failure).
