Description

Technical Field

[0001] This application relates to a power equipment operation condition monitoring device, belonging to the field of power equipment monitoring technology. Background Technology

[0002] Power equipment refers to all electrical and mechanical devices used in the production, transmission, distribution, conversion, control, and use of electrical energy, and is a core component of the power system. It mainly includes power generation equipment, transmission and transformation equipment, and distribution equipment, and is widely used in power plants, substations, distribution rooms, and industrial and residential power consumption sites. Modern power equipment not only performs the basic function of power transmission but also integrates sensing, communication, and edge computing capabilities, becoming an important part of the power system.

[0003] In the operation of a power system, the safe and stable operation of electrical equipment in the distribution room is crucial to ensuring power supply. Routine inspections of these devices to check their operating conditions are an essential maintenance procedure.

[0004] Traditional power equipment inspections primarily rely on manual labor and fixed monitoring devices. During manual inspections, personnel must enter the substation to observe and record instrument readings, appearance, partial discharge, temperature rise, and other indicators. This manual inspection method faces several challenges, including potential safety risks for personnel working in high-voltage environments, limitations in inspection frequency and efficiency due to manpower constraints, and the discrete nature of manually recorded data, making continuous analysis difficult. Furthermore, some concealed or high-altitude equipment areas are difficult to inspect visually, resulting in blind spots that may delay fault detection. While fixed monitoring devices can detect faults in real time, their limited detection range fails to meet the complex environmental requirements of substations, hindering timely fault detection and impacting power equipment operation.

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0051] The present application will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the application.

[0052] The power equipment operation condition monitoring device of this embodiment includes an inspection track 1, an inspection platform 10, a power collection component, a moving mechanism, and a detection component.

[0053] The mobile mechanism drives the inspection platform 10 to move within the inspection track 1. The detection component is set below the inspection platform 10 for multi-angle detection of the power equipment.

[0054] The power supply assembly includes a conductive sliding contact strip 7 and a brush 5;

[0055] The inspection platform 10 is set inside the inspection track 1, the conductive sliding contact strip 7 is set inside the inspection track 1, the low-voltage power grid of the power distribution room supplies power to the conductive sliding contact strip 7, one end of the brush 5 contacts the conductive sliding contact strip 7 to draw power, and the other end of the brush 5 supplies power to the moving mechanism and the detection component.

[0056] In this embodiment, the inspection track 1 is fixedly installed above the electrical equipment in the power distribution room that needs to be inspected. A conductive sliding contact strip 7 is provided on the inner side of the inspection track 1. The conductive sliding contact strip 7 obtains 36V of power from the low-voltage power grid of the power distribution room through a transformer, which is within the safe voltage range. The inspection track 1 is provided with mounting holes 2 for fixing. The inspection track 1 is fixedly installed through the mounting holes 2.

[0057] The inspection platform 10 is equipped with a power supply component, which includes a brush 5 that contacts the conductive sliding strip 7. The inspection platform 10 is also equipped with an identifier 12, which is used to identify the positioning code 8 to determine the position of the inspection platform 10.

[0058] In a preferred embodiment, it further includes an identifier 12, a positioning code 8, and a current sensor 14;

[0059] A positioning code 8 is set on the inspection track 1, and an identifier 12 is set on the inspection platform 10 to identify the positioning code 8 to determine the position of the inspection platform 10;

[0060] The current sensor 14 is used to monitor the current passing through the brush 5 in real time, and is configured to mark the location where the current fluctuation occurs when the current fluctuation is detected, in conjunction with the location determined by the identifier 12.

[0061] The current sensor 14 is used to monitor the current passing through the brush 5 in real time. When the current sensor 14 detects fluctuations in the current, such as being below a preset threshold or exceeding the normal range, it marks and records the location of the current fluctuation in conjunction with the current position information fed back by the identifier 12. This function is used to indicate possible power supply abnormalities on the conductive sliding contact strip 7, improving the system's ability to detect abnormalities in its own power supply link. During the movement of the inspection platform 10, the identifier 12 continuously identifies the positioning code 8. Through the positioning code 8 information obtained by identification, the identifier 12 can determine the precise position of the inspection platform 10 on the inspection track 1 in real time. This position information can be used to guide the movement control of the inspection platform 10 and the location marking for data acquisition.

[0062] Methods for marking the location of current fluctuations include:

[0063] S1. During the movement of the inspection platform 10, the system control unit synchronously triggers the current acquisition thread and the position acquisition thread to obtain the current value I(t) and the position coordinate P(t);

[0064] S2. Bind the current value I(t) and the position coordinate P(t) collected at the same time, and add a timestamp t to form a complete data packet {t,P(t),I(t)}. Temporarily store the data packet in the position-current association mapping table.

[0065] S3. Make a judgment:

[0066] If I(t) is within the normal threshold range, the power supply is determined to be normal, and the process switches to S1 for continued monitoring.

[0067] If I(t) continuously or momentarily exceeds the normal threshold range, it is determined to be a power supply abnormality, and the process proceeds to S4.

[0068] S4. When a power supply anomaly is detected, retrieve the location coordinate P(t) corresponding to the abnormal current data packet from the association mapping table, mark the location coordinate P(t) as a power supply anomaly point, and generate an anomaly record together with the timestamp of the anomaly occurrence, the abnormal current value, and the anomaly type such as: too low, too high, or fluctuation, and store it in the system's non-volatile memory.

[0069] S5 triggers the alarm procedure and reports the generated abnormal records to the remote monitoring center in real time through the built-in communication module of the inspection platform 10.

[0070] This implementation transforms traditional passive fault handling into proactive status monitoring and early warning, identifying potential problems before severe faults such as complete power outages occur. Through data synchronization and binding technology, abstract current signals are mapped one-to-one with precise spatial locations, achieving centimeter-level accurate fault location and significantly improving maintenance efficiency.

[0071] In this embodiment, the mounting bracket 13 is fixed on the inspection platform 10. The brush 5, the extrusion plate 32, and the spring 27 are installed inside the mounting bracket 13. The spring 27 extrudes the brush 5 through the extrusion plate 32, so that the brush 5 always presses against the conductive sliding contact strip 7.

[0072] Spring 27 applies pressure to brush 5 through compression plate 32. Brush 5 uses this pressure to keep the conductive sliding contact strip 7 pressed against it, thereby ensuring that the inspection platform 10 can continuously obtain power from the conductive sliding contact strip 7 during movement, providing stable power to the various functional modules of the device.

[0073] In this embodiment, the mounting bracket 13 is provided with a limiting hole 31. By pushing the extrusion plate 32 backward from the limiting hole 31, the spring 27 is compressed and contracted, thereby releasing the compression on the brush 5.

[0074] Specifically, the brush 5 is slidably installed in the limiting hole 31; when the brush 5 needs to be replaced, the spring 27 can be contracted by pushing the pressing plate 32 backward, thereby releasing the pressure on the brush 5; at this time, the brush 5 can slide out from the opening of the limiting hole 31 for replacement, and this structure is convenient for maintenance.

[0075] The moving mechanism in this embodiment includes:

[0076] Multiple casters 11 are fixed to the outside of the inspection platform 10;

[0077] A servo motor 15 is fixedly connected inside the inspection platform 10 and is used to drive at least one of the moving wheels 11 to move on the inspection track 1.

[0078] In this embodiment, the inspection track 1 is provided with grooves 9 on both sides, and the moving wheel 11 moves within the grooves 9.

[0079] The inspection platform 10 can move on the inspection track 1. When the inspection platform 10 moves, its moving wheels 11 always move within the range of the slide groove 9. The slide groove 9 is used to prevent the inspection platform 10 from shifting laterally and avoid it from colliding with the inspection track 1.

[0080] Specifically, multiple moving wheels 11 in the moving mechanism are arranged on the outside of the inspection platform 10 and cooperate with the slide groove 9 on the inspection track 1. They move within the slide groove 9 to guide the movement of the inspection platform 10 and maintain its stability. A support plate is fixedly connected inside the inspection platform 10, and a servo motor 15 is fixedly connected to the support plate. One moving wheel 11 is fixedly connected to the output end of the servo motor 15. The servo motor 15 drives the moving wheel 11 connected to it to rotate by precisely controlling the rotation of its output shaft. Through the drive of the moving wheel 11 by the servo motor 15, the inspection platform 10 can move precisely along a preset path within the inspection track 1.

[0081] The inspection platform 10 in this embodiment also includes an adjustment device, which includes an adjustment rod 16, a first large gear 17, a second large gear 18, a first bevel gear 19, a second bevel gear 20, a rotating rod 21, a rotating frame 22, a first motor 23, a second motor 24, a first small gear 25, and a second small gear 26.

[0082] The detection component is fixed to the bottom of the rotating frame 22, the two ends of the rotating rod 21 are fixed to the rotating frame 22, the lower end of the adjusting rod 16 is connected to the rotating rod 21 through a bearing, and the upper end of the adjusting rod 16 is fixed with a second bevel gear 20.

[0083] The first large gear 17 and the second large gear 18 are located above the second bevel gear 20;

[0084] The first bevel gear 19 is fixedly connected to the outside of the rotating rod 21 and meshes with the second bevel gear 20.

[0085] The output shaft of the second motor 24 drives the second pinion 26 at its end to rotate, and the second pinion 26 meshes with the second large gear 18.

[0086] The second large gear 18 is fixedly connected to the second bevel gear 20. When the second large gear 18 rotates, it drives the second bevel gear 20 to rotate synchronously.

[0087] The rotation axis of the second bevel gear 20 coincides with the axis of the adjusting rod 16, the rotation axis of the first bevel gear 19 coincides with the axis of the rotating rod 21, and the axis of the adjusting rod 16 is perpendicular to the axis of the rotating rod 21.

[0088] The second bevel gear 20 and the first bevel gear 19 form a bevel gear pair. When the second bevel gear 20 rotates, it redirects the power 90 degrees through the first bevel gear 19, driving the first bevel gear 19 and the rotating rod 21 to rotate together.

[0089] When horizontal angle adjustment is required, the first motor 23 starts, and its output drives the first pinion 25 to rotate. The first pinion 25 drives the first large gear 17 meshing with it to rotate. The rotation of the first large gear 17 drives the adjusting rod 16 fixedly connected to it to rotate around its own axis, thereby driving the rotating frame 22 and the mounting plate 4 connected to the adjusting rod 16 to rotate in the horizontal direction, so as to realize the adjustment of the horizontal observation angle of the detection equipment.

[0090] When pitch angle adjustment is required, the second motor 24 starts, and its output drives the second pinion 26 to rotate. The second pinion 26 drives the second large gear 18 to rotate, thereby driving the second bevel gear 20, which is fixedly connected to the second large gear 18, to rotate around the axis of the adjusting rod 16. The second bevel gear 20 meshes with the first bevel gear 19. The rotation of the second bevel gear 20 will drive the first bevel gear 19 to rotate, thereby driving the rotating rod 21, which is fixedly connected to it, to rotate around its own axis. The rotation of the rotating rod 21 causes the rotating frame 22 and the mounting plate 4 fixed at both ends to produce pitch motion, so as to realize the adjustment of the vertical observation angle of the detection equipment.

[0091] This embodiment enables the detection device to be adjusted in both horizontal and vertical dimensions by working in coordination or independently of the first motor 23 and the second motor 24, ensuring all-round observation of the power equipment.

[0092] The detection components in this embodiment include a camera 3, an infrared thermal imager 28, a gas sensor 29, and an ultrasonic sensor 30.

[0093] In this embodiment, camera 3 is used to collect visible light image data to observe the appearance of the equipment and the status of indicator lights; infrared thermal imager 28 is used to collect thermal distribution data of the equipment to detect abnormal temperature rise; gas sensor 29 is used to detect the concentration of specific gases in the power distribution room to detect insulation gas leakage or decomposition products; and ultrasonic sensor 30 is used to collect high-frequency sound wave signals generated by the operation of the equipment to detect abnormalities such as partial discharge.

[0094] An insulating groove 6 is provided on the inspection track 1 in this embodiment, and a conductive sliding contact strip 7 is disposed in the insulating groove 6. The insulating groove 6 is used to electrically insulate the conductive sliding contact strip 7 from the inspection track 1, thereby preventing leakage.

[0095] Working principle: First, use bolts to pass through the mounting holes 2 on the inspection track 1 and fix the inspection track 1 to the special bracket on the top of the power distribution room that needs to be inspected. Then, install the inspection platform 10 inside the inspection track 1, so that the brush 5 on the top of the inspection platform 10 contacts the conductive sliding contact strip 7 fixed inside the inspection track 1. The conductive sliding contact strip 7 draws power from the lighting circuit through the transformer, and the conductive sliding contact strip 7 is installed inside the inspection track 1 through the insulating groove 6. The brush 5 is pressed tightly against the conductive sliding contact strip 7 by the spring 27 and the pressing plate 32 to achieve uninterrupted power supply.

[0096] The servo motor 15 installed inside the inspection platform 10 is driven by the power provided by the brush 5, which drives the moving wheel 11 at the output end to rotate, allowing the inspection platform 10 to move inside the inspection track 1 via the external moving wheel 11. The identifier 12 set on the top of the inspection platform 10 achieves positioning by reading the positioning code 8 signal, and can accurately stop at preset points such as transformers and low-voltage cabinets. This allows the inspection platform 10 to automatically cruise along a preset path or stop in front of a designated power equipment in response to remote commands. At the same time, the slide groove 9 set on the inspection track 1 can provide guidance for the movement of the inspection platform 10 and prevent the inspection platform 10 from shaking when moving via the moving wheel 11.

[0097] When the inspection platform 10 moves, the current sensor 14 installed inside the inspection platform 10 can monitor the current passing through the brush 5 in real time. When the brush 5 moves to a certain position on the conductive sliding contact bar 7 and generates current fluctuations, the brush 5 will detect and give feedback. The identifier 12 will send a signal according to the position to mark the current position information, so that the staff can receive the position where the current fluctuations occur through the network, which is convenient for maintenance.

[0098] The inspection platform 10 is equipped with an infrared thermal imager 28, a gas sensor 29, an ultrasonic sensor 30, and a camera 3. During the inspection, information in the power distribution room is collected. The collected data is transmitted to the power distribution room edge gateway through the built-in module of the inspection platform 10, and then uploaded to the remote monitoring platform via the wide area communication network.

[0099] During inspection, the servo motor 15 drives the moving wheels 11 to move the inspection platform 10 to the vicinity of the equipment to be inspected. The first motor 23 is started, which drives the first pinion 25 at the output end to rotate. Through the meshing of the first pinion 25 with the first large gear 17, the first large gear 17 and the adjusting rod 16 fixed to the first large gear 17 are driven to rotate. The adjusting rod 16 drives the rotating frame 22 and the mounting plate 4 at the bottom to rotate, adjusting the various detection devices and cameras 3 set on the mounting plate 4. Then, the second motor 24 is driven to drive the second pinion 26 at the output end to rotate, so that the second large gear 18 rotates on the adjusting rod 16, driving the second bevel gear 20 fixed to it to rotate, thereby driving the meshing first bevel gear 19 to rotate. This allows the rotating rod 21 and the rotating frame 22 fixed to it to rotate through the drive of the first bevel gear 19, adjusting the angle of the mounting plate 4 to facilitate the inspection of the equipment.

[0100] Under normal circumstances, the inspection platform 10 can collect data every 15 minutes. If the temperature change exceeds the threshold or other abnormal reactions are detected, it is determined to be an abnormal state and a high-priority data reporting process is immediately initiated. After receiving the report, the staff can actively control the inspection platform 10 to go to the location of the abnormality and conduct manual observation through the camera 3 to maintain the abnormal point.

[0101] When the brush 5 needs to be replaced, simply push the first motor 23 backward to squeeze the spring 27 between the squeezing plate 32 and the mounting bracket 13, causing the spring 27 to contract. Then slide the brush 5 from the limiting hole 31 to the opening, remove the brush 5 and replace it with a new brush 5. Then release the squeezing plate 32 and use the spring 27 to squeeze the brush 5 through the squeezing plate 32 so that the brush 5 contacts the conductive sliding contact strip 7 to draw power.

10. The power equipment operating condition monitoring device according to claim 1, characterized in that, Methods for marking the location of current fluctuations include: S1. During the movement of the inspection platform (10), the system control unit synchronously triggers the current acquisition thread and the position acquisition thread to obtain the current value I(t) and the position coordinate P(t); S2. Bind the current value I(t) and the position coordinate P(t) collected at the same time, and add a timestamp t to form a complete data packet {t,P(t),I(t)}. Temporarily store the data packet in the position-current association mapping table. S3. Make a judgment: If I(t) is within the normal threshold range, the power supply is determined to be normal, and the process switches to S1 for continued monitoring. If I(t) continuously or momentarily exceeds the normal threshold range, it is determined to be a power supply abnormality, and the process is switched to S4. S4. When a power supply anomaly is detected, retrieve the location coordinate P(t) corresponding to the abnormal current data packet from the association mapping table, mark the location coordinate P(t) as a power supply anomaly point, and generate an anomaly record together with the timestamp of the anomaly occurrence, the abnormal current value, and the anomaly type, and store it in the system's non-volatile memory: S5. Trigger the alarm procedure and report the generated abnormal records to the remote monitoring center in real time through the built-in communication module of the inspection platform (10).
