A surround detection module and a driving mechanism are installed inside the distribution cabinet body. A blowing unit is configured on the output end of the driving mechanism. A first anti-interference unit and a second anti-interference unit are configured on the blowing end of the blowing unit.

Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet detection, and more specifically, to a power distribution cabinet with intelligent detection of fault points. Background Art

[0002] With the increasing demand for the intelligence of power systems, modern power distribution cabinets are generally integrated with fault detection modules to monitor the status of key contacts in real time. In current technologies, non-contact detection means, such as infrared imaging or visual recognition, are mainly used to locate fault points. Such systems generally detect the temperature rise caused by the change of contact resistance of contacts to achieve fault early warning. The core logic is to associate abnormal temperature with physical states such as contact aging and loosening, and then drive maintenance responses.

[0003] However, the above detection means are susceptible to environmental interference in practical applications. For example, when dust is electrostatically adsorbed on the contacts to form a local insulating layer, the surface temperature distribution deviates from the actual contact state, resulting in misjudgment of hot spots or missed detection of actual faults by the thermal imaging system. In addition, non-contact scanning is easily affected by air flow disturbances inside the cabinet. For example, the temperature detection module described in the patent number CN118572524B is prone to form monitoring blind spots due to uneven air convection in densely wired areas, and redundant sensors need to be additionally configured, increasing costs and complexity.

[0004] Therefore, the essence of the interference problem lies in the lack of active environmental regulation ability in the current detection systems. Taking the intermittent hot spots caused by poor contact as an example, traditional solutions rely on passive heat dissipation to reduce the temperature rise, but they cannot eliminate the dust adhesion caused by static electricity accumulation. For example, the infrared scanner described in the patent number CN117214625A has imaging distortion due to the occlusion of dust clusters under dynamic loads, resulting in a significant increase in the false alarm rate. Therefore, the fault point detection module in the above technologies is difficult to actively eliminate interference sources and optimize the detection environment with a new structure during the working process to improve the accuracy and reliability of fault location. Summary of the Invention

[0005] Aiming at the problems existing in the above technologies, the purpose of the present invention is to provide a power distribution cabinet with intelligent detection of fault points, aiming to solve the above technical problems.

A gear sleeve ring is fixedly installed at the middle position inside the arc-shaped card slot. The protruding end of the trigger rod is a spherical structure and is meshed and clamped in the tooth gap of the gear sleeve ring.

[0014] As a further solution of the present invention: an additional cylinder is fixedly installed at the bottom of the second cylindrical sleeve. A plurality of anti-static brushes are fixedly installed on the inner wall of the additional cylinder. A guide rod is fixedly connected to the lower surface of the circular partition. The guide rod integrally penetrates into the inside of the additional cylinder and passes out from the inside of the additional cylinder. A joint sleeve is fixedly installed at the passing-out end of the guide rod. An external wire is fixedly connected to the joint sleeve and is connected to the output end of the ion generator through the external wire.

[0015] As a further solution of the present invention: the second anti-interference unit further includes an outer casing fixedly installed outside the joint sleeve. The outer casing entirely covers the outside of the fan-shaped sleeve cavity, and the inner wall of the outer casing fits the outer surface of the fan-shaped sleeve cavity. A plurality of nano-needle array electrodes are fixedly installed on the outer circular ring surface of the outer casing, and the nano-needle array electrodes do not contact the fan blades located in the inner ring of the ring sleeve frame. Scrubbing plates are fixedly installed on the side surface of the fan blades facing the electrostatic adsorption filter screen, and the scrubbing ends of the scrubbing plates are in correspondence with and fit the electrostatic adsorption filter screen.

[0016] As a further solution of the present invention: a reserved slot is opened on the side wall of the cylindrical sleeve shell.

And at the outer edge position of the surface on the side where the pushing head protrudes, a first return spring ring is fixedly installed. At the center position of the surface on the side where the pushing head protrudes, an extension rod is fixedly installed. The whole extension rod passes through the first cylindrical sleeve, and a ball is fixedly installed at the protruding end. A circular opening is provided on the side wall of the arc-shaped card slot for the ball to pass through and fit the circular ring sleeve frame.

[0018] As a further solution of the present invention: A shielding cover plate is fixedly installed on the side wall of the connecting socket head.

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] Through the dynamic environment regulation and multi-modal detection cooperation mechanism, this solution improves the accuracy and anti-interference ability of the fault point detection of the power distribution cabinet. Aiming at the problem that traditional infrared scanning is easily affected by static electricity dust accumulation and air flow disturbance, the arc-shaped sleeve housing frame is driven by a linear motor to perform a circumferential scan along the outer side of the electrical component table. Combining the initial positioning of the first infrared detection head and the cooperative tracking of the second infrared detection head eliminates the monitoring blind area. The integrated design of the blowing unit and the anti-interference unit enables the high-speed air flow driven by the servo motor to not only remove the dust accumulation in the detection area, but also form an ion wind curtain by the collision of dielectric particles to generate electricity, dynamically neutralize the static electricity interference on the detection path, and solve the problem of temperature imaging distortion caused by dust adhesion.

[0021] Combining mechanical collision ionization and controllable ion emission to construct an adaptive electromagnetic shielding environment. Dielectric particles are subjected to high-frequency collisions with the cavity wall under the action of centrifugal force in the fan-shaped cavity, and charge separation is achieved through the work function difference. Cooperating with the enhanced ionization of the nano-needle array electrode, a positive and negative ion flow surrounding the detection area is formed. The reciprocating spring rod module drives the guide rod to intermittently contact the fan-shaped cavity through the periodic meshing of the trigger rod and the gear sleeve ring, which not only avoids continuous friction loss on the electrode surface, but also improves the charge transfer efficiency through particle oscillation.

[0022] Through the innovation of modular structure design and intelligent control logic, a closed-loop system of detection, cleaning, and protection is constructed. The tightness control unit dynamically adjusts the damping pressure of the ball on the circular ring sleeve frame through the electric telescopic rod, and cooperates with the switching of the adsorption state of the electromagnetic control head to achieve precise adaptation between the blowing speeds. The third infrared detection head works in cooperation with the scraping plate in the low-speed scanning mode to continuously remove impurities on the surface of the electrostatic adsorption filter in real time, ensuring the stability of the detection optical path, and is especially suitable for industrial scenarios with high humidity and a lot of dust.

[0046] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for schematic needs and is not intended to limit the present invention to this specific structure, device and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0047] The following will describe in detail a power distribution cabinet with intelligent detection of fault points provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. Those skilled in the art in some well-known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0048] As Figures 1 to 11As shown in the figure, an embodiment of the present invention provides a power distribution cabinet with intelligent detection of fault points, including a power distribution cabinet body 1 and a plurality of electrical component tables 2 fixedly installed inside the power distribution cabinet body 1. A circumferential detection module 4 is installed inside the power distribution cabinet body 1, and the circumferential detection module 4 is integrally sleeved outside all the electrical component tables 2. A driving mechanism 5 facing the side of the electrical component table 2 is configured on the circumferential conveying end of the circumferential detection module 4. An output end of the driving mechanism 5 is configured with a blowing unit 52, and a first anti-interference unit 7 and a second anti-interference unit 8 are configured on a blowing end of the blowing unit 52;

[0049] The blowing unit 52 includes a cylindrical sleeve 521. An arc-shaped card slot 523 is opened on a side of the cylindrical sleeve 521 facing the electrical component table 2. The first anti-interference unit 7 includes a circular ring sleeve frame 71 movably installed in the arc-shaped card slot 523. The second anti-interference unit 8 includes a plurality of sector-shaped sleeve frames 81 fixedly installed at equal intervals in a circumferential manner on an outer ring edge of the circular ring sleeve frame 71. An ion generator 82 is fixedly installed on an outer ring surface of each sector-shaped sleeve frame 81, and a sector-shaped sleeve cavity 84 is fixedly installed on an inner ring surface of each sector-shaped sleeve frame 81. A number of dielectric particles are filled inside the sector-shaped sleeve cavity 84;

[0050] The blowing unit 52 blows air towards the side of the electrical component table 2 to drive the circular ring sleeve frame 71 to rotate synchronously, so that the dielectric particles filled inside the sector-shaped sleeve cavity 84 reciprocally contact an output end of the ion generator 82 to generate an anti-interference air duct to assist in fault point detection.

[0051] To solve the problems in the prior art that non-contact fault point detection means are vulnerable to environmental interference, resulting in misjudgment and missed detection, and lack a structure for actively eliminating interference sources, affecting the detection accuracy and reliability, the above technical solution is now adopted to solve the problem. The above technical solution mainly consists of a distribution cabinet body 1, an electrical component table 2, a surrounding detection module 4, a driving mechanism 5, a first anti-interference unit 7, and a second anti-interference unit 8. The distribution cabinet body 1 is a cabinet structure for installing various electrical components in the prior art. The configured electrical component table 2 is a connection meter structure in the prior art, used for connecting or transferring wires. The set surrounding detection module 4 is in an overall runway shape and is sleeved outside the electrical component table 2, used to control the driving mechanism 5 on the runway-shaped guide rail to move reciprocally, so that the driving mechanism 5 can be used to detect the front side of the electrical component table 2 and can also be moved to detect the rear side of the electrical component table 2 to scan and monitor some blocked interface areas. A blowing unit 52 is configured on the output end of the driving mechanism 5, and the first anti-interference unit 7 and the second anti-interference unit 8 are both configured on the blowing end of the blowing unit 52. By driving the blowing unit 52 to blow air outwards during the working process, on the one hand, the dust accumulated in the area to be detected is blown away, and on the other hand, the heat in this area can also be blown away, reducing the interference caused by the heat generated by the surrounding components to the area to be detected. And most importantly, the wind force can drive the ring sleeve frame 71 in the arc-shaped card slot 523 to rotate, so that the dielectric particles filled in the fan-shaped sleeve cavity 84 reciprocally contact the output end of the ion generator 82. The dielectric particles move at high speed in the air flow, collide with the metal air duct wall of the fan-shaped sleeve cavity 84 or adjacent particles. The collision causes electrons to escape from the material surface, making the dielectric particles positively charged and the air duct wall negatively charged, or vice versa, depending on the material work function difference. The configured dielectric particles can be selected as alumina particles. The charged particles enter the ion emission area, that is, the output end of the ion generator 82, and interact with the high-voltage electric field to enhance the ionization efficiency. Cooperating with the blown air duct to form a high-speed air flow that wraps the ion flow, the ions and the air flow synchronously cover the target area, neutralize static electricity while blowing away dust, achieving the effect of anti-static interference and assisting in fault point detection.

[0052] Such as Figures 1 to 11As shown in the figure, the wrap-around detection module 4 includes a linear motor 41 fixedly installed on the inner side wall of the distribution cabinet body 1. A plurality of first infrared detection heads 42 are fixedly installed on the outer surface of the linear motor 41. A circular arc sleeve frame 43 is fixedly installed on the output end of the linear motor 41. The circular arc sleeve frame 43 is integrally sleeved outside all the electrical component tables 2. A plurality of second infrared detection heads 44 are fixedly installed on the inner circular ring surface of the circular arc sleeve frame 43 facing the electrical component table 2. A wrap-around drive track sleeve 45 is fixedly installed at the bottom of the circular arc sleeve frame 43. The drive mechanism 5 includes a connection socket 51 fixedly installed on the output end of the wrap-around drive track sleeve 45. A servo motor 53 is fixedly installed at the exact bottom of the connection socket 51. The cylindrical sleeve 521 is fixedly installed on one side of the bottom of the connection socket 51 at the output end of the servo motor 53.

[0053] Among them, the configured linear motor 41 is a motor structure for linear drive in the prior art, which is used to drive the circular arc sleeve frame 43 to move up and down, so that the second infrared detection head 44 on the inner wall of the circular arc sleeve frame 43 can move to the side of the electrical component table 2 at any height position. The configured first infrared detection head 42, the second infrared detection head 44, and the third infrared detection head 77 described later are all probe structures in the prior art for infrared scanning to obtain the heat information of the scanned area. The difference is that the first infrared detection head 42 is used for initial scanning monitoring. Because the first infrared detection heads 42 are installed in rows on the outer surface of the linear motor 41 and face the side electrical component table 2, it can be known which height of the side electrical component table 2 has a temperature difference. After finding that there is a temperature difference at a certain height, the linear motor 41 drives the circular arc sleeve frame 43 to move up and down to reach this position. Because after the circular arc sleeve frame 43 moves to this position, it will cover the first infrared detection head 42 at this position to achieve the purpose of moving and positioning. And because the circular arc sleeve frame 43 is similar to a runway-shaped guide rail, it can drive the detection end to surround the electrical component table 2 at this height for further accurate scanning to find out which contact has a temperature abnormality at this height position, so as to provide real-time feedback on the faulty contact.

[0054] Such as Figures 1 to 11As shown, the interior of the cylindrical housing 521 has a cavity structure, and a fan head 525 fixedly connected to the output end of the servo motor 53 is movably installed at the position of the inner center of the cavity. A solenoid control head 72 is fixedly installed at the center position of the ring-shaped sleeve frame 71, and a groove socket 73 is formed on the side of the solenoid control head 72 facing the fan head 525. A magnetic attraction sleeve head 74 movably sleeved in the groove socket 73 is fixedly installed at the center position of the fan head 525. A plurality of fan blades 75 are fixedly installed on the inner ring surface of the ring-shaped sleeve frame 71 around the outer side of the solenoid control head 72. A third infrared detection head 77 is fixedly installed on the side of the solenoid control head 72 opposite to the side where the groove socket 73 is formed.

[0055] Among them, the configured servo motor 53 is a motor structure capable of servo drive in the prior art, which is used to drive the fan head 525 at the output end to rotate to generate an air duct. The groove socket 73 is used to provide a slot for the ring-shaped sleeve frame 71 to rotate. After the fan head 525 generates an air duct, it can drive the ring-shaped sleeve frame 71 at the air outlet to rotate, similar to the structure of the self-rotating air guide cover of an electric fan in the prior art. Since the third infrared detection head 77 configured at the outer center position of the ring-shaped sleeve frame 71 is the axis center, the scanning end will not be affected when the structure rotates. The configured solenoid control head 72 is a device capable of electromagnetic control in the prior art, which can control the magnetic attraction as a whole in the groove of the groove socket 73 to control the connection state with the fan blades 75. When the solenoid control head 72 is turned on, there is a magnetic attraction effect in the groove of the groove socket 73, and the entire ring-shaped sleeve frame 71 can be adsorbed on the magnetic attraction sleeve head 74, that is, it is an integral structure with the fan head 525. At this time, the fan head 525 rotates at a high speed, and the ring-shaped sleeve frame 71 can also rotate at a high speed. When the solenoid control head 72 is turned off, there is no magnetic attraction effect in the groove of the groove socket 73. At this time, the groove socket 73 and the magnetic attraction sleeve head 74 are in a movable sleeve relationship. At this time, when the fan head 525 rotates, the ring-shaped sleeve frame 71 will only rotate due to the blowing force, and the difference is that the rotation speed drops significantly. The reason for the significant drop in speed is to provide a better scanning state, and the reason for its high-speed rotation is to make the dielectric particles collide at a high speed to generate a more stable and efficient anti-interference air duct.

[0056] As Figures 1 to 11As shown, the second anti-interference unit 8 further includes a movable shaft rod 85 movably installed at the axial center position of the sector-shaped sleeve cavity 84. Swing blocks 86 are fixedly installed at both side ends of the movable shaft rod 85, and a stirring rod 87 is fixedly installed between the two swing blocks 86. A number of leakage openings 88 are formed on the outer circular ring surface of the sector-shaped sleeve cavity 84. Reciprocating spring rod modules 83 are fixedly installed at both side ends of the sector-shaped sleeve frame 81. An electrostatic adsorption filter screen 55 is fixedly installed on the outer surface of the circular arc card slot 523. A wiping protection head 56 is fixedly installed at the center position of the electrostatic adsorption filter screen 55.

[0057] Among them, the configured sector-shaped sleeve cavity 84 is as described above, which is used to fill dielectric particles and cooperate with the rotation of the device to reciprocally collide to generate an electrified effect to enhance the anti-static air duct. The movable shaft rod 85 configured at the axial center position of the sector-shaped sleeve cavity 84 is to enable the two outer swing blocks 86 to rotate in each sector-shaped sleeve cavity under the action of centrifugal force during the rotation process, so that the stirring rod 87 fixedly installed between the two swing blocks 86 drives the internal particles to move, further enhancing the fluidity of the internal particles to further enhance the electrified effect. Because it is an air duct with an electrified effect, an electrostatic adsorption filter screen 55, such as a metal sintered filter screen in the prior art, is configured on the air outlet side to limit the discharge energy below the minimum ignition energy of the gas to enhance safety. The wiping protection head 56 is a protective film structure in the prior art, similar to the protective film of a screen, and can transmit scanning light.

[0058] As Figures 1 to 11 shown, the reciprocating spring rod module 83 includes a second cylindrical sleeve 831. A second return spring ring 833 is fixedly installed inside the second cylindrical sleeve 831, and a circular partition plate 832 slidably clamped inside the second cylindrical sleeve 831 is fixedly installed at the return end of the second return spring ring 833. A trigger rod 834 is fixedly installed on the upper surface of the circular partition plate 832. The trigger rod 834 entirely passes through the sector-shaped sleeve frame 81. A gear collar 524 is fixedly installed at the middle position inside the circular arc card slot 523. The protruding end of the trigger rod 834 is a spherical structure and is meshed and clamped in the tooth slot of the gear collar 524.

[0059] As Figures 1 to 11 shown, an additional cylindrical barrel 835 is fixedly installed at the bottom of the second cylindrical sleeve 831. A number of anti-static brushes 837 are fixedly installed on the inner wall of the additional cylindrical barrel 835. A guide rod 836 is fixedly connected to the lower surface of the circular partition plate 832. The guide rod 836 entirely penetrates into the additional cylindrical barrel 835 and passes out from the inside of the additional cylindrical barrel 835. A joint sleeve 810 is fixedly installed at the passing-out end of the guide rod 836. An external connecting wire 89 is fixedly connected to the joint sleeve 810 and is connected to the output end of the ion generator 82 through the external connecting wire 89.

[0060] The configured reciprocating elastic rod module 83 is used to provide reciprocating ejection, so that the reciprocating elastic rod module 83 outside the reciprocating elastic rod module 83 drives the outer shell 811 to reciprocately fit the fan-shaped sleeve cavity 84 to generate intermittent charged air ducts. The specific working principle is as follows:

[0061] After the annular sleeve 71 rotates following the rotation of the blowing unit 52, the trigger rod 834 on the reciprocating elastic rod module 83 will be reciprocatingly stuck in the teeth of the gear ring 524, and under the reset force of the second reset spring coil 833, the guide rod 836 moves up and down following the jumping of the trigger rod 834 in the teeth of the gear ring 524, which is reflected on the guide rod 836 as the outer shell 811 on the outside of the guide rod 836 reciprocatingly fits the fan-shaped sleeve cavity 84. After fitting the fan-shaped sleeve cavity 84, a charging effect can be generated, and the charging effect is lost after separation, thereby reducing the continuous friction of particles on the electrode surface and reducing material fatigue loss. In addition, intermittent contact allows the particles to be fully charged between two collisions, and the charge transfer amount of a single contact is higher than that of continuous contact. Most importantly, through intermittent impact of particles, dust adsorbed on the electrode surface can be shaken off, thereby reducing the deposition rate of pollutants.

[0062] The configured ion generator 82 is an ion emitting device in the prior art, and the generating end is transferred to the outer shell 811 through an external wire 89. The nano needle array electrode 812 on the outer shell 811 is a tungsten needle electrode arranged in a ring in the prior art to generate positive and negative alternating ion flow. In order to ensure the safety of the outer compressed air channel, its cylindrical shell 521 has a Permalloy coating to attenuate external magnetic field interference.

[0063] like Figures 1 to 11 As shown, the second anti-interference unit 8 also includes a jacket shell 811 fixedly installed on the outside of the joint sleeve 810, and the jacket shell 811 as a whole covers the outside of the fan-shaped sleeve cavity 84, and the inner wall of the jacket shell 811 is in contact with the outer surface of the fan-shaped sleeve cavity 84, and a plurality of nano-needle array electrodes 812 are fixedly installed on the outer circular ring surface of the jacket shell 811, and the nano-needle array electrode 812 is not in contact with the fan blade 75 located in the inner ring of the circular sleeve frame 71, and a scraper plate 76 is fixedly installed on the surface of the fan blade 75 on one side facing the electrostatic adsorption filter 55, and the scraping end of the scraper plate 76 is in contact with the electrostatic adsorption filter 55.

[0064] like Figures 1 to 11As shown, a reserved notch 522 is provided on the side wall of the cylindrical housing 521. Inside the reserved notch 522, two sets of tension control units 6 spaced 180 degrees apart are fixedly installed. The tension control unit 6 includes a first cylindrical sleeve 61. On the outer side of the first cylindrical sleeve 61, an electric telescopic rod 62 is fixedly installed, and one side of the output end of the electric telescopic rod 62 extends into the interior of the first cylindrical sleeve 61.

[0065] As Figures 1 to 11 shown, the tension control unit 6 further includes a push head 64 slidably installed inside the first cylindrical sleeve 61. One side of the electric telescopic rod 62 extending into the interior of the first cylindrical sleeve 61 is fixedly connected to the push head 64. At the outer edge position of the surface on the side where the push head 64 protrudes, a first return spring ring 63 is fixedly installed. At the center position of the surface on the side where the push head 64 protrudes, an extension rod 65 is fixedly installed. The whole of the extension rod 65 passes through the first cylindrical sleeve 61, and a ball 66 is fixedly installed at the protruding end. On the side wall of the arc-shaped card slot 523, there is an opening for the ball 66 to pass through and fit against the circular ring sleeve frame 71.

[0066] Among them, the configured tension control unit 6 is used to control the tightness of the fit between the outer side wall of the circular ring sleeve frame 71 and the inner wall of the arc-shaped card slot 523. Because after the adsorption effect of the groove sleeve opening 73 is cancelled by the electromagnetic control head 72, the circular ring sleeve frame 71 can rotate synchronously under the blowing action of the blowing unit 52. In order to control the rotation speed of the circular ring sleeve frame 71 in this state and ensure the stability during the detection by the third infrared detection head 77 on the circular ring sleeve frame 71, it is necessary for the tension control unit 6 to control the tightness of the sliding surface. Specifically, it is manifested as:

[0067] One end of the ball 66 protrudes through the opening on the side wall of the arc-shaped card slot 523 under the restoring force of the first return spring ring 63 and fits against the side wall of the circular ring sleeve frame 71. And because the trigger rod 834 of the reciprocating spring rod module 83 on the circular ring sleeve frame 71 also acts reciprocally with the gear ring 524, as shown in the attached Figure 5 figure, the cross-sectional view of the side of the circular ring sleeve frame 71 is actually concave, and the trigger rod 834 is at the concave notch position. Therefore, the outer edge of the circular ring sleeve frame 71 fitting against the inner wall of the arc-shaped card slot 523 does not interfere with the trigger rod 834. Under the restoring force of the first return spring ring 63, the ball 66 is pressed tightly against the side of the circular ring sleeve frame 71, so that the circular ring sleeve frame 71 is subjected to a damping effect on the side wall during rotation, thereby reducing the rotation speed. Further, by extending the electric telescopic rod 62 outward, the first return spring ring 63 is further tightened, and the ball 66 outside the extension rod 65 is more tightly pressed against the side wall of the circular ring sleeve frame 71, and the rotation speed can be further reduced.

[0068] As Figures 1 to 11As shown, a cover plate 54 is fixedly installed on the side wall of the connecting socket head 51. The side edge of the cover plate 54 is arc-shaped and is integrally attached to the inner circular ring surface side of the arc-shaped sleeve frame 43 to cover the second infrared detection head 44. An outward-opening door panel 3 is hinged on the outer end of the power distribution cabinet body 1.

[0069] Among them, the configured cover plate 54 is used to cover the second infrared detection head 44 to determine the position of the driving mechanism 5 in real time.

[0070] The usage method provided by the present invention is as follows:

[0071] When the present invention is in use, it can be divided into two parts: initial processing and fault scanning. The initial processing is used to serve the fault scanning;

[0072] Initial processing stage: The electromagnetic control head 72 controls the groove socket 73 at the output end to tightly adsorb the magnetic adsorption socket head 74 outside the fan head 525, so that the circular ring sleeve frame 71 and the fan head 525 are temporarily combined into an integral structure. At this time, the servo motor 53 is turned on, and the fan head 525 at the output end of the servo motor 53 is controlled to rotate at a high speed. The air duct generated by the high-speed rotation of the fan head 525 blows outwards. The driving mechanism 5 is controlled to move to the target area to be detected through the surrounding detection module 4, and the target area can be cleaned by the blowing force. Then the ion generator 82 is turned on. The outer casing 811 at the output end of the ion generator 82 reciprocally fits the fan-shaped cavity 84 under the reciprocating action of the reciprocating spring rod module 83, and forms an anti-static air duct in cooperation with the blown air to further process the area to be detected.

[0073] Fault scanning stage: The electromagnetic control head 72 controls the groove socket 73 at the output end to cancel the adsorption. At this time, the magnetic adsorption socket head 74 and the groove socket 73 are in an active state. Then, through the control reservation of the tightness control unit 6, the tightness of the side wall of the circular ring sleeve frame 71 is controlled. At this time, during the operation of the blowing unit 52, the circular ring sleeve frame 71 is driven by the wind force. In this state, the third infrared detection head 77 is turned on to perform exhaust air scanning on a point, ensuring that the influence of static electricity, electromagnetic interference, and dust coverage can be effectively reduced during the detection of this contact point, and the fault point can be accurately scanned.
