Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and in particular to an intelligent distribution box wiring detection device. Background Technology

[0002] A distribution box is a metal or plastic box that houses electrical components such as switches, circuit breakers (air switches), residual current devices (RCDs), and meters. It mainly uses wires to connect various electrical appliances. To improve safety, a wiring test is performed before using the distribution box. The main testing equipment is an infrared detector. The test is completed by moving the infrared detector along the wire to be tested. However, in actual testing, the conductor to be measured is affected by other nearby conductors, which leads to certain errors in the measurement results of the infrared detector. Furthermore, when the infrared detector is moved manually during testing, it cannot be guaranteed that the distance between the infrared detector and the conductor is at a fixed value, which will further increase the measurement error of the infrared detector. Moreover, the infrared detector is in a translational state, and the single-angle, static measurement has inherent physical limitations, which will further increase the measurement error of the infrared detector. Therefore, an intelligent distribution box wiring testing device is provided. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent distribution box wiring detection device.

[0004] The present invention adopts the following technical solution: An intelligent distribution box wiring detection device includes a main body, a fixed ring fixedly mounted on the main body, a rotating ring rotatably mounted on the fixed ring via a rotating assembly, multiple fixed blocks fixedly mounted inside the rotating ring, a round rod slidably mounted on each fixed block, and an infrared detector fixedly mounted on the round rod. A control component is fixedly installed inside the rotating ring. The control component can automatically drive a part of the round rod to move back and forth relative to the fixed block, thereby adjusting the detection position of part of the infrared detector, enriching experimental data, and reducing experimental errors. The control assembly includes a control arc-shaped plate slidably mounted within a fixed ring. A through slot is formed in the fixed block. A second rack is fixedly mounted on the round rod. A control shaft is rotatably mounted within the through slot. Two third gears are fixedly sleeved on the control shaft. One of the third gears meshes with the second rack. A control plate is slidably connected within the through slot. A first rack is fixedly connected to the control plate. The other third gear meshes with the first rack. A control rod, positioned corresponding to the control arc-shaped plate, is fixedly connected to the control plate. The rotating ring is connected to the control arc plate via a swing assembly.

[0005] Preferably, the oscillating assembly includes a rotating shaft rotatably mounted within a fixed ring, a second bevel gear fixedly connected to the rotating shaft, a first bevel gear fixedly connected to the rotating ring, the first and second bevel gears meshing with each other, a cam fixedly connected to the rotating shaft, the cam having an annular groove, a slide rod slidably connected to the annular groove, a movable plate fixedly connected to the slide rod, the movable plate slidably connected to the fixed ring, a movable rod fixedly connected to the movable plate, a movable arc plate fixedly connected to the movable rod, and a control arc plate fixedly connected to the movable arc plate.

[0006] Preferably, the control arc plate has multiple grooves evenly distributed on one side, and each groove has a chamfer at the bottom.

[0007] Preferably, a limiting component is fixedly installed inside the rotating ring, and the limiting component can adjust the initial position of the round rod, thereby limiting the movement distance of the round rod.

[0008] Preferably, the limiting component includes a hydraulic cylinder fixedly installed inside a rotating ring, a movable ring fixedly installed at the output end of the hydraulic cylinder, a plurality of connecting rods rotatably connected to the movable ring, the positions and number of the plurality of connecting rods being opposite to the round rod, a limiting ring rotatably connected to the plurality of connecting rods, a limiting ring being slidably connected to an infrared detector, and a plurality of springs fixedly installed between the round rod and the through groove.

[0009] Preferably, a limit rod is fixedly installed in the through groove, and the control plate and the limit rod are slidably connected up and down.

[0010] Preferably, the rotating assembly includes a micro motor fixedly installed inside a fixed ring, a first gear fixedly connected to the outer side of the output shaft of the micro motor, and a second gear fixedly connected to the outer side of the rotating ring, wherein the first gear and the second gear mesh with each other.

[0011] Preferably, both the fixed ring and the rotating ring have openings on their outer sides, and a PTFE-coated O-ring is fixedly installed in each of the openings.

[0012] The beneficial effects of this invention are: 1. First, when testing the wiring of the distribution box, the wire to be tested is first passed through the PTFE-coated O-ring, and then the corresponding electrical signal is applied to start the distribution box, putting the wire to be tested into working condition. Then, the tester holds the main body and moves it along the wire to be tested, starting the micro motor to drive the round rod and infrared detector to rotate. This can greatly reduce the detection blind spots of the infrared detector, and by analyzing the change law of radiation intensity at different angles, it is possible to distinguish between the wire's own radiation and reflected radiation, and to eliminate reflected interference. Furthermore, the distance between the wire to be measured and the infrared detector is a fixed value, reducing measurement errors and thus improving the accuracy of the test results. 2. Secondly, when using an infrared detector for detection, it will also move some of the infrared detectors closer to the wire to be measured, thereby changing the position of the infrared detectors, further reducing blind spots, and by analyzing the variation of radiation intensity at different positions, further eliminating reflection interference, thereby improving the accuracy of the detection results. 3. Finally, the two control rods located on the lower side of the control arc plate will be at different heights due to the groove, which in turn will cause the two infrared detectors to be in different positions. When using the infrared detectors for detection, the electrical signals emitted by the two infrared detectors can be compared and analyzed again to eliminate reflection interference and improve the accuracy of the detection results.

[0015] See Figures 1-11 An intelligent distribution box wiring detection device includes a main body 1. A fixed ring 2 is fixedly installed on the side wall of the main body 1. A rotating ring 3 is rotatably installed on the fixed ring 2 via a rotating assembly. The rotating assembly includes a micro motor 5 fixedly installed inside the fixed ring 2. A first gear 6 is fixedly connected to the outer side of the output shaft of the micro motor 5. A second gear 11 is fixedly connected to the outer side of the rotating ring 3. The first gear 6 and the second gear 11 mesh with each other. Multiple fixed blocks 16 are fixedly installed on the rotating ring 3. A round rod 25 is slidably installed on each fixed block 16. An infrared detector 17 is fixedly installed on the outer side of the round rod 25. Both the fixed ring 2 and the rotating ring 3 have openings on their outer sides, and a PTFE-coated O-ring is fixedly installed in each opening. First, a PTFE-coated O-ring is a composite sealing element that wraps or coats a layer of polytetrafluoroethylene (PTFE, commonly known as Teflon) material onto the surface of a base elastomer (such as rubber). It combines the elastic recovery capability of rubber with the ultra-low friction, high temperature resistance, and corrosion resistance of PTFE. Second, the infrared detector 17 is a device that measures the temperature of an object or generates a temperature distribution image by detecting the infrared radiation emitted by the object. When the distribution box is working, the connected wires automatically heat up due to the flow of current. At this time, the infrared detector 17 can detect the surface temperature of the wires. Furthermore, a touch switch controlling the micro motor 5 and infrared detector 17 is fixedly installed on the outside of the main body 1. During testing, the testing personnel can hold the main body 1 and press the corresponding switch to start the micro motor 5 or the infrared detector 17. Additionally, a display screen is fixedly installed on the outside of the main body 1. The infrared detector 17 is connected to the display screen via wireless transmission technology. When the infrared detector 17 is performing testing, it can wirelessly transmit the detected electrical signal to the display screen, which then presents it to the testing personnel. Then, when testing the wiring of the distribution box, first pass the wire to be tested through the PTFE-coated O-ring, and then make the corresponding electrical connection. Start the distribution box to put the wire to be tested into working condition. Then, the tester holds the main body 1 and moves it along the wire to be tested. The main body 1 moves the fixed ring 2, the fixed ring 2 moves the rotating ring 3, and the rotating ring 3 moves the round rod 25 and the infrared detector 17. The infrared detector 17 can detect the surface temperature of the wire to be tested and transmit the detected electrical signal to the display screen on the outside of the main body 1. The tester can observe the data on the outside of the display screen to determine whether the wire to be tested is qualified, and finally complete the corresponding test operation. During the aforementioned detection process, the micro motor 5 can be activated. The micro motor 5 drives the rotating ring 3 to rotate via the first gear 6 and the second gear 11. The rotating ring 3 drives the round rod 25 and the infrared detector 17 to rotate, which can greatly reduce the detection blind spot of the infrared detector 17. Furthermore, since the infrared detector 17 is in a rotating state, by analyzing the variation law of radiation intensity at different angles, it is possible to distinguish between the self-radiation and reflected radiation of the conductor (self-radiation changes slowly with the angle, while reflected radiation changes drastically), thus eliminating reflection interference and improving the accuracy of the detection results.

[0016] A control component is fixedly installed inside the rotating ring 3. The control component can automatically drive part of the round rod 25 to move back and forth relative to the fixed block 16, adjust the position of part of the round rod 25 relative to the fixed block 16, and thus adjust the detection position of part of the infrared detector 17, enriching experimental data and reducing experimental errors. The control assembly includes a control arc-shaped plate 18 slidably mounted within a fixed ring 2. A through groove 22 is formed on the side wall of a fixed block 16. A second rack 33 is fixedly mounted on the side wall of a round rod 25. A control shaft 31 is rotatably mounted within the through groove 22. Two third gears 32 are fixedly sleeved on the outside of the control shaft 31, one of which meshes with the second rack 33. A control plate 24 is slidably connected within the through groove 22. A first rack 30 is fixedly connected to the side wall of the control plate 24, and the other third gear 32 meshes with the first rack 30. A control rod 23, corresponding in position to the control arc-shaped plate 18, is fixedly connected to the side wall of the control plate 24. A limit rod 29 is fixedly mounted within the through groove 22. The control plate 24 and the limit rod 29 are slidably connected vertically. The rotating ring 3 is connected to the control arc plate 18 via a swing assembly. The swing assembly includes a rotating shaft 8 rotatably installed inside the fixed ring 2. A second bevel gear 7 is fixedly connected to the outside of the rotating shaft 8. A first bevel gear 4 is fixedly connected to the upper side of the rotating ring 3. The first bevel gear 4 and the second bevel gear 7 mesh with each other. A cam 9 is fixedly connected to the outside of the rotating shaft 8. Annular grooves 15 are opened on both sides of the cam 9. Slide rods 14 are slidably connected in both annular grooves 15. A moving plate 10 is fixedly connected to the outside of both slide rods 14. The moving plate 10 and the fixed ring 2 are slidably connected up and down. A moving rod 12 is fixedly connected to the lower side of the moving plate 10. A moving arc plate 13 is fixedly connected to the lower side of the moving rod 12. The moving arc plate 13 and the control arc plate 18 are fixedly connected. First, during the up-and-down movement of the arc plate 18, at least two adjacent control rods 23 on the outer side of the infrared detectors 17 will always be located below the moving arc plate 13. Second, during the rotation of the rotating ring 3, the rotating ring 3 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the second bevel gear 7 to rotate, the second bevel gear 7 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the cam 9 to rotate. Since the moving plate 10 and the fixed ring 2 are slidably connected, and the slide rod 14 and the annular groove 15 are slidably connected, during the rotation of the cam 9, the sliding rod 14 drives the moving plate 10 to move up and down. The moving plate 10 drives the moving arc plate 13 to move up and down via the moving rod 12. The moving arc plate 13 drives the control arc plate 18 to move up and down. The control arc plate 18 and the control rod 23 abut against each other, thereby driving the control rod 23 to move downward. The control lever 23 drives the control plate 24 to move downwards, which in turn drives the first rack 30 to move downwards. The first rack 30 drives the meshing third gear 32 to rotate clockwise. The third gear 32 drives another third gear 32 to rotate clockwise via the control shaft 31. The third gear 32 drives the meshing second rack 33 to move closer to the conductor to be measured. The second rack 33 drives the round rod 25 to move closer to the conductor to be measured. While the round rod 25 stretches the spring 26, it also drives the infrared detector 17 to move closer to the conductor to be measured, thereby changing the position of the infrared detector 17. This further reduces the blind spot in the image. By analyzing the variation of radiation intensity at different positions, it is possible to distinguish between the conductor's own radiation and reflected radiation (the conductor's own radiation changes gradually with the angle, while reflected radiation changes drastically), thus eliminating reflection interference and improving the accuracy of the detection results.

[0017] The control arc plate 18 has multiple grooves 19 evenly opened on one side, and each groove 19 has a chamfer at the bottom. When the control arc plate 18 and the control lever 23 abut against each other, at least two control levers 23 are located on the lower side of the control arc plate 18. The following explanation will take the example of two control levers 23 on the lower side of the control arc plate 18. Figure 7 From the perspective of the control rod 23, when one control rod 23 is located on the lower left side of the control arc plate 18 and the other control rod 23 is located on the lower right side of the control arc plate 18, under the constraint of the groove 19, when the control rod 23 located on the lower right side of the control arc plate 18 is located in the groove 19 and abuts against the inner wall of the groove 19, the two control rods 23 will be at different heights, which will cause the two infrared detectors 17 to be in different positions as well. When using the infrared detectors 17 for detection, the electrical signals emitted by the two infrared detectors 17 can be compared and analyzed again, which can eliminate reflection interference and improve the accuracy of the detection results.

[0018] A limiting component is fixedly installed inside the rotating ring 3. The limiting component can adjust the initial position of the round rod 25, thereby limiting the movement distance of the round rod 25. The limiting component includes a hydraulic cylinder 21 fixedly installed inside the rotating ring 3. A moving ring 20 is fixedly installed at the output end of the hydraulic cylinder 21. Multiple connecting rods 28 are rotatably connected to the side wall of the moving ring 20. The position and number of the multiple connecting rods 28 are opposite to the round rod 25. A limiting ring 27 is rotatably connected to the side of the multiple connecting rods 28 away from the moving ring 20. The limiting ring 27 is slidably connected to the infrared detector 17. Multiple springs 26 are fixedly installed between the round rod 25 and the through groove 22. First, during testing, without external force, the hydraulic cylinder 21 is in a closed state and in a self-locking state, which causes the moving ring 20, connecting rod 28, and limiting ring 27 to be in a fixed state. At this time, under the obstruction of the limiting ring 27 and with the spring 26 in a deformed state, the infrared detector 17 and the limiting ring 27 abut against each other. As a result, during the testing process of the infrared detector 17, if the control rod 23 does not abut against the control arc plate 18, the infrared detector 17 is in a fixed state relative to the rotating ring 3. Second, when the infrared detector 17 is used for testing, if the infrared detector 17 issues an abnormal signal, the entire moving body 1 stops moving. Then, the hydraulic cylinder 21 can be activated to appropriately adjust the position of the limiting ring 27, which causes the position of the infrared detector 17 to change again, further eliminating reflection interference and improving the accuracy of the test results.

[0019] In this invention, when testing the wiring of a distribution box, the wire to be tested is first passed through a PTFE-coated O-ring, and then the electrical connection is made. The distribution box is then started, putting the wire to be tested into operation. The testing personnel hold the main body 1 and move it along the wire to be tested. The main body 1 moves the fixed ring 2, rotating ring 3, round rod 25, and infrared detector 17. The infrared detector 17 detects the surface temperature of the wire to be tested and transmits the detected electrical signal to a display screen on the outside of the main body 1. The testing personnel can observe the data on the display screen to determine whether the wire to be tested is qualified, thus completing the corresponding testing operation. During the above detection process, the micro motor 5 is started. The micro motor 5 drives the rotating ring 3 to rotate through the first gear 6 and the second gear 11. The rotating ring 3 drives the round rod 25 and the infrared detector 17 to rotate, reducing the detection blind spot of the infrared detector 17 and analyzing the variation law of radiation intensity at different angles. This can distinguish between the radiation of the conductor itself and the reflected radiation, eliminate reflection interference, and thus improve the accuracy of the detection results. During the rotation of the rotating ring 3, the rotating ring 3 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the second bevel gear 7 to rotate, and the second bevel gear 7 drives the rotating shaft 8 and cam 9 to rotate. Under the action of the slide rod 14, the moving plate 10 moves up and down. The moving plate 10 drives the moving arc plate 13 and the control arc plate 18 to move up and down through the moving rod 12. The control arc plate 18 and the control rod 23 abut against each other, thereby driving the control rod 23 to move downward. The control board 24 drives the first rack 30 to move downwards, the first rack 30 drives the third gear 32 to rotate, the third gear 32 drives another third gear 32 to rotate through the control shaft 31, the third gear 32 drives the second rack 33 to move, the second rack 33 drives the round rod 25 to move, the round rod 25 stretches the spring 26 and also drives the infrared detector 17 to move, thereby changing the position of the infrared detector 17, further reducing the blind spot of the shooting, and thus improving the accuracy of the detection results; When the control arc plate 18 and the control rod 23 are in contact, if one control rod 23 is located on the lower left side of the control arc plate 18 and the other control rod 23 is located on the lower right side of the control arc plate 18, under the constraint of the groove 19, the control rod 23 located on the lower right side of the control arc plate 18 will be located in the groove 19 and in contact with the inner wall of the groove 19. This will cause the two control rods 23 to be at different heights, which will in turn cause the two infrared detectors 17 to be in different positions. When using the infrared detectors 17 for detection, the electrical signals emitted by the two infrared detectors 17 can be compared and analyzed again to eliminate reflection interference and improve the accuracy of the detection results.
