Description

Technical Field

[0001] The present application relates to the technical field of busbar insulation detection, and in particular to a device for detecting the insulation status of a busbar. Background Art

[0002] Tubular busbars are a crucial piece of power transmission equipment in power systems, widely used in various electrical engineering projects and high-voltage distribution systems, particularly in high-voltage substations, distribution rooms, industrial plants, and underground power tunnels. Typically made of copper or aluminum alloy, tubular busbars have a high current-carrying capacity and can efficiently transmit electrical energy. They are typically coated with insulating material to ensure safe current transmission and prevent hazards such as short circuits and electric shock in power equipment. Furthermore, tubular busbars play a crucial role in current distribution, connection, and protection in power systems. The integrity of their insulation layer is directly related to the stable operation of the power system and the safety of personnel.

[0003] The insulation status inspection of tubular busbars currently relies primarily on visual inspection, electrical inspection, and ultrasonic inspection. Visual inspection uses a camera or optical sensor to scan the busbar surface. It can identify obvious surface defects such as cracks and scratches, but it is inadequate for detecting minor or deep-seated damage. Electrical inspection evaluates insulation performance by measuring insulation resistance. Although it can detect resistance anomalies, it can only identify surface or near-surface damage and cannot fully assess deep-seated defects. Ultrasonic testing identifies cracks or pores by analyzing sound wave reflections. It is suitable for detecting structural defects, but its ability to detect surface microcracks or minor damage is limited, and its operation is relatively complex.

[0004] Although common tubular busbar insulation detection technologies can identify defects on the surface or inside of tubular busbars, they still face several problems. First, current detection methods lack efficient continuity and comprehensiveness. Since many detection methods rely on manual operations, it is impossible to conduct rapid and comprehensive inspections of the tubular busbar throughout the entire process. Secondly, most existing technologies are single detection methods that cannot comprehensively evaluate multiple types of damage, and lack accurate diagnosis for different degrees of damage, resulting in post-detection processing that is often inefficient or too rough. Finally, existing methods usually rely on manual follow-up processing after defects are discovered, such as marking and repair, which makes the process cumbersome and inefficient, and cannot achieve timely response and accurate repair. Summary of the Invention

[0005] In order to improve the efficiency of busbar detection and subsequent processing, the present application provides a device for detecting the insulation status of a busbar.

[0006] The present application provides a device for detecting the insulation status of a busbar, which adopts the following technical solution:

[0007] A busbar insulation status detection device is used to detect the busbar surface and perform subsequent processing, comprising two sets of semi-cylindrical clamps, the two clamps can be combined to form a complete cylindrical structure, and the connection between the two clamps is magnetically arranged, and the two clamps are provided with:

[0008] A support and guide mechanism, used to support the two clamps after being enclosed, and to drive the two clamps to slide along the length direction of the busbar;

[0009] an annular groove, wherein the two annular grooves form a complete annular groove when the two clamps are closed;

[0010] An annular guide rail, wherein the two annular guide rails form a complete annular guide rail when the two clamps are closed, and a slide seat is slidably engaged on the inner wall of the annular guide rail, and the annular guide rail can drive the slide seat to perform circular motion;

[0011] The slide is provided with the following components in sequence along the rotation direction of the slide:

[0012] Inspection mechanism, used to conduct comprehensive inspection of the busbar outer wall for surface defects, insulation performance and structural defects;

[0013] a marking mechanism for evaluating defects detected by the detection mechanism, and spraying three different colored marks at the defect locations when the busbar surface has slight damage that does not affect normal use, when the busbar surface has mild damage, and when the busbar surface has severe damage;

[0014] A repair mechanism, used for performing targeted repairs on the marks of different colors sprayed by the marking mechanism;

[0015] a display mechanism, mounted on the outside of one of the clamps, electrically connected to the detection mechanism, and configured to display different degrees of damage to the busbar surface detected by the detection mechanism;

[0016] A locking mechanism is provided inside the two clamps and is used to clamp and fix the busbar when the detection mechanism detects slight or severe damage on the busbar surface;

[0017] When the marking mechanism sprays out a mark indicating that the busbar surface is slightly damaged, the repair mechanism repairs the damaged position on the busbar surface. When the marking mechanism sprays out a mark indicating that the busbar surface is severely damaged, the marking mechanism does not repair and performs manual verification.

[0018] By adopting the above technical solution, when the busbar needs to be inspected, the two clamps are clamped outside the busbar to form a complete cylindrical structure. At this time, the two clamps are moved along the length direction of the busbar. The detection mechanism will rotate and detect the outer surface of the busbar, and the marking mechanism can mark the detection results.

[0019] When slight damage is detected on the busbar surface that does not affect normal use, the marking mechanism sprays a mark indicating that no repair or manual verification is required;

[0020] When the busbar surface is detected to be slightly damaged, the marking mechanism sprays a mark indicating that repair is required but does not require manual verification. The repair mechanism then sprays repair fluid on the mark to repair it, and the locking mechanism locks the busbar, preventing the clamp from moving along the busbar.

[0021] When severe damage is detected on the busbar surface, the marking mechanism sprays a mark indicating that no repair is required and manual verification is required. At this time, the locking mechanism will lock the busbar, preventing the clamp from moving along the busbar. The operator can then separate the two clamps to manually verify the location of the damage and determine whether an immediate power outage or even direct replacement of this section of busbar is required.

[0022] The display mechanism can clearly assist in prompting the type of defect detected at this time, so as to prompt the operator whether to continue pushing the clamp forward.

[0023] The system automatically classifies and labels defect locations throughout the entire inspection process, including repair and manual verification, significantly improving busbar inspection efficiency. This reduces time spent identifying defect locations that don't require repair or verification, further improving inspection efficiency.

[0026] By adopting the technical scheme, the optical sensor can detect surface cracks, scratches and defects on the outer surface of the busbar, the laser ranging sensor can detect irregular surfaces and depths of defects of the busbar, the ultrasonic sensor can detect deep defects, bubbles or cracks of the busbar, and the electrical sensor can detect electrical faults and insulation performance changes of the busbar.

[0027] The four sensors work in parallel, which can complete the detection of various defects of the busbar in a short time, quickly locate the defects, and significantly improve the detection efficiency. Compared with the common detection system of a single sensor or a simple method, the scheme forms a more comprehensive, accurate and rapid busbar insulation detection system through the multi-dimensional cooperation of optical, laser, ultrasonic and electrical sensors. Especially in terms of detection efficiency, accuracy, automation degree and adaptability to various types of defects, the scheme has more obvious improvement effect.

[0028] The point light source array can provide a good lighting environment for the optical sensor, the laser ranging sensor, the ultrasonic sensor and the electrical sensor, so that the optical sensor, the laser ranging sensor, the ultrasonic sensor and the electrical sensor can work normally.

[0031] Optionally, the repair mechanism comprises a repair assembly for spraying and repairing the defects on the outer surface of the busbar and a recycling assembly for recycling the excess repair paint after repair.

[0032] By adopting the above technical scheme, the repair assembly can spray paint to repair the marked position that needs to be repaired, and the recycling assembly can recycle the excess paint and scrape the paint at the defect position, so that the repair effect of the paint is better.

[0033] Optionally, the repair assembly includes a mounting seat, a driving member, a rotating shaft, a ball screw, a connecting rod, a piston, a pneumatic cylinder, a liquid storage tank and a liquid outlet pipe, the mounting seat is fixedly mounted on the sliding seat, the driving member is arranged on the mounting seat, the rotating shaft is coaxially fixed with the output shaft of the driving member, the bidirectional threaded rod of the ball screw is coaxially fixed with the rotating shaft, the ball sleeve of the ball screw is sleeved on the bidirectional threaded rod, one end of the connecting rod is connected to the ball sleeve of the ball screw, and the other end is fixedly connected to the piston;

[0035] The liquid outlet pipe is connected to the liquid storage tank, and the end thereof is arranged opposite to and close to the outer surface of the busbar. The recovery component is used to recover the excess paint sprayed from the end of the liquid outlet pipe into the liquid storage tank.

[0036] By adopting the above technical solution, after the marking mechanism has marked, the liquid outlet pipe is driven by the slide to rotate to a position facing the marking. At this time, the driving part works, the driving part drives the rotating shaft to rotate, and the rotating shaft drives the bidirectional threaded rod of the ball screw to rotate, so that the ball sleeve of the ball screw reciprocates along the bidirectional threaded rod, thereby driving the piston to reciprocate through the connecting rod. When the piston compresses the space in the air pressure cylinder, the paint in the liquid storage tank is sprayed out from the end of the liquid outlet pipe, thereby realizing the repair of the required position.

[0037] Optionally, the recovery assembly includes a driving gear, a driven gear, a recovery bucket, a connecting plate, a sealing recovery ring, and a recovery pipe, wherein the driving gear is coaxially fixed to the rotating shaft, a rotary sealing joint is provided between the liquid outlet pipe and the liquid storage tank, the liquid outlet pipe rotary seal is mounted on the rotary sealing joint, and the driven gear is coaxially fixed to the liquid outlet pipe and meshes with the driving gear;

[0040] By adopting the above technical solution, when the rotating shaft rotates, it drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear rotates the liquid outlet pipe, and thus drives the recovery bucket to make eccentric movement along the liquid outlet pipe through the connecting plate, thereby scraping off the excess paint at the spraying site. During the scraping process, the excess paint will gradually move upward along the inner wall of the recovery bucket, that is, move upward along the annular cavity;

[0041] During the reciprocating motion of the piston, when the piston moves in the direction away from the air pressure cylinder, the piston pumps air into the air pressure cylinder, so that the excess paint entering the annular cavity is returned to the recovery pipe through the sealed recovery ring and enters the air pressure cylinder through the recovery pipe. When the piston moves in the direction close to the air pressure cylinder, the paint entering the air pressure cylinder is pressed into the liquid storage tank, thereby achieving smoothing and recovery of the paint.

The telescopic part is provided in multiple groups corresponding to each clamp, and each telescopic part can drive the corresponding clamping plate to clamp and fix the outer wall of the busbar.

[0045] By adopting the above technical solution, when the sensor detects slight or severe damage on the busbar surface, the telescopic part extends, driving the clamping plate to abut the outer surface of the busbar, so that the two clamps are locked on the busbar. At this time, automatic repair or manual verification can be performed.

[0046] Optionally, the support and guide mechanism includes a fixed seat and a guide wheel arranged on the fixed seat, and the fixed seat and the guide wheel are provided in multiple groups, and each of the fixed seats is installed at intervals on the inner wall of the clamp, and the guide wheel is rotatably installed on the corresponding fixed seat and can rotate and abut against the outer wall of the busbar when the clamp moves.

[0047] By adopting the above technical solution, the guide wheel can guide the movement of the two clamps, so that the two clamps can move more easily on the busbar.

[0048] Optionally, a power supply mechanism is provided in each of the two clamps, and the power supply mechanism is electrically connected to all electrical components.

[0049] By adopting the above technical solution, the power supply mechanism can provide power to the entire system, making it convenient for operators to inspect the busbar at any time.

[0050] In summary, this application includes at least one of the following beneficial technical effects:

[0051] 1. When the busbar needs to be inspected, the two clamps are clamped together outside the busbar to form a complete cylindrical structure. At this time, the two clamps are moved along the length of the busbar. The detection mechanism will rotate and detect the outer surface of the busbar, and the marking mechanism can mark the detection results.

[0052] When the busbar surface is detected to have slight damage that does not affect normal use, the marking mechanism sprays a mark indicating that no repair or manual verification is required. This mark can be used to quickly locate the damaged area during the next inspection. When the busbar surface is detected to have minor damage, the marking mechanism sprays a mark indicating that repair is required but no manual verification is required. At this time, the repair mechanism sprays repair fluid on this mark to repair it, and the locking mechanism locks the busbar, preventing the clamp from moving along the busbar.

[0053] When severe damage is detected on the busbar surface, the marking mechanism sprays a mark indicating that no repair is required and manual verification is required.

The two clamps can then be separated, allowing manual verification of the damage location to determine whether an immediate power outage or even replacement of the busbar section is necessary. The display mechanism clearly indicates the type of defect detected, prompting the operator whether to continue pushing the clamp forward.

[0054] 2. The system can automatically classify and mark defect locations and process them throughout the entire inspection process, including repair and manual verification, significantly improving busbar inspection efficiency. This also saves time identifying defect locations that do not require repair or verification, further improving inspection efficiency.

[0099] When the rotating shaft 413 rotates, it drives the driving gear 421 to rotate, and the driving gear 421 drives the driven gear 422 to rotate, and the driven gear 422 rotates the liquid outlet pipe 419 to rotate, thereby driving the recovery bucket 423 to make eccentric movement along the liquid outlet pipe 419 through the connecting plate 424. If there is excess repair fluid during repair, when the recovery bucket 423 makes eccentric movement, the bottom of the recovery bucket 423 scrapes the repair fluid, so that the repair fluid enters the annular cavity 4231. As the repair fluid gradually accumulates in the annular cavity 4231, the repair fluid will gradually move upward on the inner wall of the annular cavity 4231, and when it moves to the sealing recovery ring 4232, it enters the sealing recovery ring 4232, and then the repair fluid is recycled through the recovery pipe 425, thereby saving the repair fluid and improving the utilization rate of the repair fluid.

[0100] During the reciprocating motion of the piston 416, when the piston 416 moves away from the air cylinder 417, the piston 416 evacuates the air cylinder 417, so that the excess paint entering the annular cavity returns to the recovery pipe 425 through the sealing recovery ring 4232, and enters the air cylinder 417 through the recovery pipe 425. In the process of the piston 416 moving toward the air cylinder 417, the paint entering the air cylinder 417 is pressed into the liquid storage tank 418, thereby achieving the smoothing and recovery of the paint.

[0101] Reference Figure 2 and Figure 3 The locking mechanism 6 includes a telescopic member 61 and a clamping plate 62 arranged at the telescopic end of the telescopic member 61. There are multiple groups of telescopic members 61 corresponding to each clamp 1, and each telescopic member 61 can drive the corresponding clamping plate 62 to clamp and fix the outer wall of the busbar.

[0102] When the sensor detects slight or severe damage on the busbar surface, the telescopic member 61 extends, driving the clamping plate 62 to abut against the outer surface of the busbar, so that the two clamps 1 are locked on the busbar. At this time, automatic repair or manual verification can be performed.

[0103] Reference Figure 1 and Figure 3 The support and guide mechanism 7 comprises fixing seats 71 and guide wheels 72 arranged on the fixing seats 71. The fixing seats 71 and the guide wheels 72 are arranged in multiple groups, the fixing seats 71 are arranged at intervals on the inner wall of the hoop 1, and the guide wheels 72 are rotatably arranged on the corresponding fixing seats 71 and can rotate and abut against the outer wall of the busbar when the hoop 1 moves. The guide wheels 72 can guide the movement of the two hoops 1, so that the two hoops 1 can move more easily on the busbar.

[0104] The implementation principle of the busbar insulation state detection device is as follows: when the busbar needs to be detected, the two hoops 1 are combined on the busbar to form a complete cylindrical structure, and then the two hoops 1 are moved along the length direction of the busbar. The detection mechanism 2 can rotate to detect the outer surface of the busbar, and the marking mechanism 3 can mark the detected result.

[0105] When the busbar surface is slightly damaged and does not affect normal use, the marking mechanism 3 sprays a mark representing that no repair or manual verification is needed.

[0106] When the busbar surface is slightly damaged, the marking mechanism 3 sprays a mark representing that repair is needed but manual verification is not needed. At this time, the repair mechanism 4 sprays repair liquid to repair the mark, and the locking mechanism 6 locks the busbar so that the hoop 1 cannot move along the busbar.

[0107] When the busbar surface is severely damaged, the marking mechanism 3 sprays a mark representing that no repair is needed and manual verification is needed. At this time, the locking mechanism 6 locks the busbar so that the hoop 1 cannot move along the busbar. At this time, the operator can separate the two hoops 1 to manually verify the damaged position and determine whether immediate power-off treatment or even replacement of the busbar section is needed.

[0108] The display mechanism 5 can obviously assist in prompting the type of defect detected at this time to prompt the operator whether the hoop 1 should continue to move forward.

[0109] The embodiment of the application also discloses a busbar insulation state detection method, which comprises the following steps:

[0110] S1: When the busbar needs to be detected, the two hoops are combined on the busbar to form a complete cylindrical structure.

[0111] S2: Slowly move the two hoops along the length direction of the busbar, and detect the surface and the inside of the busbar by the detection mechanism. When the indicator light is on, stop moving the hoop.

[0112] If the green light is on, the marking mechanism sprays a green mark.

[0113] If the yellow light is on, the marking mechanism sprays a yellow mark, the locking mechanism locks the two clamps on the busbar, and the repair mechanism sprays repair fluid to repair the yellow mark. When the repair is completed, the locking mechanism stops locking the two clamps on the busbar;

[0114] If the red light is on, the marking mechanism sprays a red mark, and the locking mechanism locks the two clamps to the busbar. The two clamps are manually separated, and the damage at the red mark is manually inspected to determine whether it is necessary to immediately shut down the power supply or replace this section of the busbar.

[0115] S3: If the yellow light is on, the detection mechanism detects the shape, size and glue amount of the repair fluid at the yellow mark. If the shape, size and glue amount of the repair fluid are all qualified, the marking mechanism sprays a green mark to cover the yellow mark. If any of the shape, size and glue amount of the repair fluid is unqualified, the repair mechanism performs a second repair on the shape, size and glue amount of the repair fluid at the yellow mark. This step is repeated until the shape, size and glue amount of the repair fluid at the yellow mark are qualified.

[0116] S4: When the clamp moves to the end of the busbar, it moves in the opposite direction, and the detection mechanism detects the green mark. When it moves to the pure green mark, the detection mechanism continues to move. When it detects the green mixed with yellow mark, the locking mechanism locks and the detection mechanism performs a repair quality inspection on the mixed mark. If the repair quality is qualified, the locking mechanism unlocks. If the repair quality is unqualified, the green and yellow indicators light up at the same time, and the locking mechanism locks the clamp on the busbar.

[0117] S5: When the green and yellow lights are on at the same time, separate the clamps, manually check the mixed green and yellow marks, and perform manual repairs.

[0118] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
