Description
Technical Field
[0001] This disclosure relates to the field of fault detection equipment for distribution boxes, and more particularly to a fault detection device for intelligent distribution boxes. Background Technology
[0002] To ensure the safe operation of distribution boxes, it is often necessary to use distribution box fault detection equipment to perform real-time monitoring of the distribution boxes.
[0003] Patent application CN202410806300.2 discloses a fault detection device for a power distribution box in operation. Through the configuration of a docking seat and a handheld detector, the detector can be placed inside the power distribution box during assembly, while the docking seat, electrically connected to the detector, is installed on the outside of the box. When testing is needed, simply plugging the handheld detector into the docking seat allows for the acquisition of the internal temperature of the box, thus avoiding potential hazards from opening the box door and improving testing safety. Furthermore, by connecting the handheld detector to the docking seat, when the motor is started, the docking seat can be activated via a drive belt. The reciprocating screw rotates, and the arrangement of the reciprocating screw, moving rod, and movable seat forms a bidirectional screw slide that can automatically move in opposite directions. Therefore, the movable seat can move back and forth along the reciprocating screw, allowing the detector to scan and move simultaneously. Compared to fixed-point temperature scanning, this setup provides a wider sampling area and higher data reliability, ensuring accurate temperature acquisition of the distribution box without opening the box door, thus facilitating accurate fault detection. Through the cooperation of the first rack, double-meshing gear, and second rack, when the movable seat pushes the abutment rod, the bracket rods on both sides move simultaneously outwards, ensuring that the transmission mechanisms on both sides of the reciprocating screw unlock and lock simultaneously. Furthermore, the stabilizing rod ensures that when the moving rod flips... The movable seat remains vertical, and through the arrangement of the stop block, air bladder, and piston block, the piston block protrudes outward to abut against the stabilizing rod at the moment the moving rod flips, enhancing the stability of the movable seat, reducing the wear on the reciprocating screw thread and other parts caused by the vibration of the moving rod flipping, extending the service life of parts, improving the reliability of the automatic dynamic scanning detection of the detector, and thus extending the timeliness of the detection method of this solution; the invention patent with patent application number CN202310230891.9 discloses a fault detection device and detection method for power distribution box maintenance. The operator operates according to the feedback from the camera. Through the operation of the drive shaft, two sets of opposing rotating gears are driven to rotate. This involves driving the clamping claws to perform relative clamping operations. The clamping claws are equipped with an internal circuit detection unit. Simultaneously, the clamping claws perform maintenance work, clamping and removing damaged electrical components from the distribution box. This avoids the safety hazards associated with manual removal of electrical components by maintenance personnel. The distribution box is secured by a fixing block and a sliding plate, ensuring its stability and preventing shaking during testing. The universal joint has a ball at its bottom, connecting to a second connecting rod. The connection end between the second connecting rod and the universal joint is a hollow cavity, where the ball at the bottom of the universal joint is placed. The ball's rotation within the second connecting rod allows for multi-angle rotation and angle adjustment, enabling better testing.
[0004] According to its publicly available technical solutions, existing distribution box fault detection equipment has several drawbacks. First, when detecting large fluctuations in the power supply current of the distribution box, it can only display and record the data through instruments, failing to issue timely alarms, thus compromising power supply safety. Second, during power distribution, when current fluctuations occur in a particular circuit, the overall power consumption may be too high, making the fluctuations less noticeable and hindering the detection of current and troubleshooting of faulty circuits. Third, when alternating between different distribution circuits, current fluctuations generated during the alternating operation can interfere with the detection structure, compromising its reliability.

[0017] The technical solution provided in this disclosure may include the following beneficial effects: In use, each row of switches in the distribution cabinet is connected to an inner ring. Then, the first guide ring and the wire are connected to a power system. The motor drives the inner shaft to rotate inside the support sleeve. As the inner shaft drives the rotating plate to rotate inside the support sleeve, it pushes the rollers on the slide rod towards the inside of the slide groove. This causes the slide rod to move towards the inside of the slide sleeve, compressing the second spring. The inner ring on the slide rod moves from the inside of the first guide ring to the inside of the second guide ring. This changes the power supply circuit of the power system corresponding to that inner ring from direct power supply through the first guide ring to power supply through the second guide ring and the wire. For a period of time, the inner ring is in contact with both the first and second guide rings simultaneously. This results in almost no pressure difference when the inner ring contacts and separates from the first and second guide rings, effectively preventing electrical sparks and ensuring power supply safety. When the power system experiences [failure / damage], [further action is taken]. When poor circuit contact or equipment malfunction causes large current fluctuations, the current in the conductors changes continuously, leading to changes in the magnetic force generated by the iron core. This, in turn, causes the iron core to exert a changing attraction on the flapper, resulting in continuous movement of the flapper under the elastic force of spring one. This movement forces air through one-way valve one into the inner side of the sleeve between the iron core and the flapper, and then through a connecting pipe and one-way valve two to the bottom of the cylinder. The increasing air at the bottom of the cylinder effectively pushes the piston upwards, pressing buttons one and two, thus activating the alarm. This system can directly issue an alarm when poor contact or equipment malfunction causes current fluctuations, eliminating the need for personnel to constantly check instruments or current data. This improves the safety of the power distribution cabinet and provides a safe, intelligent power distribution system.
[0018] During use, when the piston moves upward to the top of the cylinder, button two turns off the motor, the inner shaft and the rotating plate stop rotating, and the rotating plate stops rotating while maintaining pressure on the roller. Personnel can identify the corresponding switch group and electrical system by checking the position of the sliding sleeve corresponding to the rotating plate, eliminating the need to check each switch group and electrical system one by one. This allows personnel to quickly find the source of the fault and improve work efficiency. When the piston moves up and down, it can drive the connecting sleeve to insert into the lubricating oil inside the spacer and cylinder, thereby effectively lubricating the cylinder and piston and ensuring smooth piston movement.
[0019] During use, when the inner shaft drives the rotating plate to rotate from one roller to another, the rotating plate presses the button three between the two adjacent rollers, which in turn opens the solenoid valve. After the solenoid valve opens, the air at the bottom of the cylinder is discharged outward through the exhaust pipe, which in turn causes the piston to move the connecting sleeve downward. The magnetic field change generated by the wire during the alternating switching process causes the flap to send some air into the bottom of the cylinder. This allows the piston to return to its original position each time the electrical system is switched for testing, thus avoiding false alarms caused by the superposition of air supply and ensuring the reliability of the testing work.

[0022] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, this disclosure proposes a fault detection device for an intelligent distribution box, comprising: a power distribution assembly, the power distribution assembly including a distribution cabinet 1 and a cabinet door 2, an indicating assembly mounted on the distribution cabinet 1, the indicating assembly including an instrument 3 and an alarm 4, a power supply assembly mounted inside the distribution cabinet 1, the power supply assembly including a main switch 6 and a switch group 7; and a fault detection assembly, the fault detection assembly including a sleeve 8 and a cylinder 9, the sleeve 8 being bolted to the inner wall of the top of the distribution cabinet 1, a magnetic assembly mounted inside the sleeve 8, the magnetic assembly including an iron core 10 and a wire 11, and a movable assembly mounted inside the sleeve 8, the movable assembly including a flap 12 and a spring 13. A connecting assembly is installed on the cylinder 9, including a connecting pipe 15 and a one-way valve 16. An exhaust assembly is installed on the cylinder 9, including an exhaust pipe 17 and a solenoid valve 18. A lifting assembly is installed on the inner side of the cylinder 9, including a piston 19 and a connecting sleeve 21. An electronic control assembly is installed on the top of the cylinder 9, including a button 22 and a button 23. A support assembly is also installed, including a support sleeve 24 and a motor 26. The top of the support sleeve 24 is bolted to the inner wall of the top of the distribution cabinet 1. A sliding assembly is installed on the support sleeve 24, including a sliding sleeve 25 and a sliding rod 30. A rotating assembly is installed on the support sleeve 24, including an inner shaft 27. The sliding rod 30 is equipped with a moving assembly, which includes a roller 31 and a spring 32. A conversion assembly, including a guide ring 34 and a guide ring 35, is mounted on the sliding sleeve 25. One side of the cabinet door 2 is hinged to one side of the distribution cabinet 1, and the other side is fixed to the distribution cabinet 1 by a door lock. The cabinet doors 2 are symmetrically distributed on one side of the distribution cabinet 1. The instrument 3 is bolted to the cabinet door 2. The alarm 4 is bolted to the top of the distribution cabinet 1. A support plate 5 is bolted to the inside of the distribution cabinet 1. The main switch 6 is bolted to the support plate 5. The switch assembly 7 is bolted to the support plate 5. The support plate 5 and the switch assembly 7 are evenly distributed. Located inside the distribution cabinet 1, button 1 22 is connected to alarm 4 via wire, button 23 is connected to motor 26 via wire, and button 23 is a normally closed push-button switch. Button 3 29 is connected to solenoid valve 18 via wire, switch group 7 is connected to inner ring 33 via wire, and guide ring 2 35 is connected to wire 11 via wire. A groove is provided on the inner wall of the support sleeve 24, and button 3 29 is welded to the inner wall of the groove. An annular groove is provided on the slide rod 30, and inner ring 33 is fitted inside the annular groove. Guide ring 1 34 is engaged on the inner wall of the slide groove, and guide ring 2 35 is engaged on the inner wall of the slide sleeve 25. The inner diameters of guide ring 1 34 and guide ring 2 35 are equal to the outer diameter of inner ring 33.
[0024] Understandably, in this intelligent power distribution system, when the inner shaft 27 drives the rotating plate 28 to rotate from one roller 31 to another, the rotating plate 28 will press the button 29 between two adjacent rollers 31, thereby causing the button 29 to open the solenoid valve 18. After the solenoid valve 18 opens, the air at the bottom of the cylinder 9 is discharged outward through the exhaust pipe 17, which in turn causes the piston 19 to drive the connecting sleeve 21 to move downward. The magnetic field change generated by the wire 11 during the alternating switching process causes the flap 12 to send some air into the bottom of the cylinder 9, thereby restoring the position of the piston 19 each time the power system is switched for testing, thus avoiding false alarms caused by the superposition of air supply, and ensuring the reliability of the testing work.
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the cylinder 9 is welded to the bottom of the sleeve 8. One end of the iron core 10 is bolted to the inner wall of one end of the sleeve 8, and the other end of the iron core 10 is secured to the inner wall of the sleeve 8 by a sealing ring. One end of the wire 11 is located on the outside of the sleeve 8, and the other end of the wire 11 passes through the sleeve 8, wraps around the outer side of the iron core 10, passes through the inner wall of the sleeve 8, and extends to the outside of the sleeve 8. The outer side of the flap 12 is secured to the inner wall of the other end of the sleeve 8 by a sealing ring. The flap 12 is connected to the inner wall of the other end of the sleeve 8 by a spring 13. A one-way valve 14 is installed on the inner side of the flap 12. The top end of the connecting pipe 15 is sealed to the bottom of the sleeve 8 by threads and a sealing gasket, and the bottom end of the connecting pipe 15 is sealed to the bottom of the sleeve 8 by threads and a sealing gasket. A gasket is installed at the bottom of cylinder 9. Sleeve 8 is connected to the bottom of cylinder 9 via connecting pipe 15. One-way valve 16 is installed on connecting pipe 15. The outer side of piston 19 is clamped to the inner wall of cylinder 9. Spacer 20 is welded to the inner wall of the bottom of cylinder 9. Connecting sleeve 21 is welded to the bottom of piston 19. Connecting sleeve 21 is sleeved on the outside of spacer 20. Lubricating oil is installed on the outside of spacer 20. Manifold 17 is welded to the bottom of cylinder 9. The bottom of cylinder 9 is connected to the inner side of cylinder 9 via manifold 17. Solenoid valve 18 is installed on manifold 17. Button 1 22 and Button 2 23 are both bolted to the inner wall of the top of cylinder 9. Button 1 22 and Button 2 23 are both located on the top of piston 19.
[0026] Understandably, in this intelligent power distribution system, when the piston 19 moves upward to the top of the cylinder 9, button 23 shuts off the motor 9, the inner shaft 27 and the rotating plate 28 stop rotating, and the rotating plate 28 stops rotating and maintains the pressing action on the roller 31. Personnel can determine the corresponding switch group 7 and power system by checking the position of the sliding sleeve 25 corresponding to the rotating plate 28, without having to check the switch group 7 and power system one by one. This allows personnel to quickly find the source of the fault and improve work efficiency. When the piston 19 moves up and down, it can drive the connecting sleeve 21 to insert into the inner side of the lubricating oil between the spacer 20 and the cylinder 9, thereby effectively lubricating the cylinder 9 and the piston 19 and ensuring the smooth movement of the piston 19.
[0027] like Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 As shown, the motor 26 is bolted to the bottom of the support sleeve 24. Both ends of the inner shaft 27 are respectively mounted on the top and bottom of the support sleeve 24 via bearings. The output shaft of the motor 26 is keyed to the bottom end of the inner shaft 27. The inner shaft 27 is installed at the center of the support sleeve 24. The rotating plate 28 is welded to the outer side of the inner shaft 27, with one side of the rotating plate 28 close to the inner wall of the support sleeve 24. The sliding sleeves 25 are welded to the outer side of the support sleeve 24 and are evenly distributed on the support sleeve 24. The inner side of the slide rod 30 is provided with a sliding groove, and the outer side of the slide rod 30 is engaged with the inner wall of the sliding groove. The diameter of the sliding groove is equal to the inner diameter of the sliding sleeve 25. One end of the slide rod 30 is provided with a groove, and one end of the second spring 32 is welded to the inner wall of the groove. The other end of the second spring 32 passes through the groove and is welded to the inner wall of the sliding sleeve 25. A connecting block is installed on the slide rod 30. The connecting block passes through the sliding groove and extends to the inner side of the support sleeve 24. The roller 31 is installed on the connecting block through a rotating shaft. The roller 31 is located inside the support sleeve 24.
[0028] Understandably, during use, each row of switch group 7 in the distribution cabinet 1 is connected to an inner ring 33, and then the guide ring 34 and wire 11 are connected to an electrical system. The motor 26 drives the inner shaft 27 to rotate inside the support sleeve 24. When the inner shaft 27 drives the rotating plate 28 to rotate inside the support sleeve 24, it will push the rollers 31 on the slide rod 30 towards the inside of the slide groove, thereby causing the slide rod 30 to compress the spring 3 on the inside of the slide sleeve 25. 2. Movement: The inner ring 33 on the slide rod 30 moves from the inside of the first guide ring 34 to the inside of the second guide ring 35. This causes the power supply circuit of the electrical system corresponding to the inner ring 33 to switch from direct power supply through the first guide ring 34 to power supply through the second guide ring 35 and the wire 11. The inner ring 33 will be in contact with both the first guide ring 34 and the second guide ring 35 simultaneously for a period of time. This ensures that there is almost no pressure difference when the inner ring 33 contacts and separates from the first guide ring 34 and the second guide ring 35, effectively preventing electric sparks and ensuring... To ensure power supply safety, when the power system experiences poor circuit contact or equipment malfunction leading to large current fluctuations, the current in conductor 11 will continuously change, causing the magnetic force generated by the iron core 10 to continuously change. This results in a continuous change in the attraction of the iron core 10 to the flap 12, causing the flap 12 to move continuously under the elastic force of spring 13. This allows air to be supplied through one-way valve 14 to the inside of the sleeve 8 between the iron core 10 and the flap 12, and then through connecting pipe 15 and one-way valve 16 to the bottom of cylinder 9. The increasing air at the bottom of cylinder 9 effectively pushes piston 19 upward, causing piston 19 to move upward and press button 22 and button 23, thus activating alarm 4. This system can directly issue an alarm when the power system experiences poor contact or equipment malfunction leading to current fluctuations, eliminating the need for personnel to constantly check instrument 3 or current data. This improves the power distribution safety of distribution cabinet 1 and provides a safe and intelligent power distribution system for the power system.
