Description

Technical Field

[0001] This invention relates to an inspection device for a coke oven basement in the field of equipment inspection technology in the coking industry, and particularly to a dust-proof and high-temperature resistant inspection device for a coke oven basement and its corresponding system. Background Technology

[0002] The coke oven basement, as the core hub of coking production, houses critical equipment such as gas pipelines, temperature control devices, valves, levers, and waste gas control panels. The operational status of this key equipment directly determines the safety and continuity of coking production, necessitating periodic inspections to identify potential malfunctions such as equipment jamming. However, the ambient temperature in the coke oven basement remains between 40-60℃ year-round, with some areas reaching over 70℃ due to equipment heat dissipation. Secondly, the dust concentration is as high as 5-10 mg / m³, with dust particles mostly ranging from 0.1-10 micrometers in size, making them prone to adsorption and deposition. Finally, the basement is cramped, with crisscrossing pipelines, creating a complex working environment.

[0003] Therefore, traditional manual inspections have significant drawbacks, such as high labor intensity, low inspection efficiency, and safety risks including gas leak poisoning, high-temperature burns, and dust inhalation. Currently, inspection work is typically performed by inspection robots, which often employ ground-walking or suspended track designs. Inspection robots are usually equipped with data acquisition modules that use cameras to capture images and perform image recognition to monitor equipment operating status.

[0004] Because inspection robots need to monitor the operation of equipment installed in the coke oven basement for extended periods in the high dust concentration and high temperature environment, they often malfunction. While attempts have been made to protect the robots with transparent glass or plastic covers, these covers tend to accumulate dust, leading to significant errors in visual inspection. Furthermore, the large area of ​​coke oven basements necessitates the use of integrated protective covers to cover a wide area, often requiring assembly to achieve the required dimensions. This demands a high degree of airtightness at the assembly points. Although the sealed environment isolates dust, it also hinders heat dissipation, causing unstable operation. These factors combined make it difficult for existing dust-resistant and high-temperature inspection equipment for coke oven basements to function effectively in the complex environment of large areas with high dust concentrations and high temperatures. Summary of the Invention

[0005] (1) Technical problems to be solved To address the technical problem that existing dust-proof and high-temperature-resistant inspection equipment for coke oven basements cannot perform normal visual inspections in the complex environment of large areas, high dust concentrations, and high temperatures in coke oven basements, this invention provides a dust-proof and high-temperature-resistant inspection equipment and system for coke oven basements.

[0006] (2) Technical solution The first aspect of this invention provides a dust-proof and high-temperature-resistant inspection device for coke oven basements, comprising: A baseboard fixed to the ceiling of the basement; The track is installed on the side of the substrate away from the top plate; Inspection robots installed on and moving along a track are used to monitor the operation of equipment installed in the basement. It also includes: a protective cover, installed on the side of the base plate away from the top plate, which encloses the base plate to form a sealed cavity for housing the track and inspection robot; the protective cover is made of several transparent polycarbonate pipes spliced ​​along the extension direction of the track, and the pipe splices are connected by flanges and have built-in fluororubber sealing rings with a sealing rating of IP65 or higher; the inner and outer surfaces of the protective cover are made to have a surface resistivity of ≤10 Ω. 9 Ω antistatic polishing treatment; A cooling system is used to cool a sealed cavity.

[0007] As a further improvement to the above solution, the dust-proof and high-temperature-resistant inspection equipment for the coke oven basement also includes: Two axial flow fans are each installed inside a bypass duct. The circulating airflow of each axial flow fan is obliquely introduced into the protective cover through two air guide pipes, providing airflow power inside the protective cover. One axial flow fan provides the main airflow power inside the protective cover, while the other axial flow fan provides remote positive / negative pressure, forming a master-slave linkage to balance the pressure inside the protective cover.

[0008] As a further improvement to the above solution, the protective cover has an inspection port through which the inspection robot can be inspected; the protective cover is equipped with an inspection plate that is movably connected to the inspection port by a snap-fit, which is used to close or open the inspection port.

[0009] As a further improvement to the above solution, the protective cover is a ring-shaped channel formed by splicing several pipes.

[0010] As a further improvement to the above solution, the charging station for the inspection robot is installed on the base plate inside the protective cover.

[0011] As a further improvement to the above solution, the cooling device is a variable frequency air conditioner or a dry air cooler.

[0012] As a further improvement to the above solution, the sealed cavity is designed to allow for the circulation of cold air.

[0013] As a further improvement to the above solution, the cooling air device and the protective cover are connected by an air duct, with the air duct and the protective cover forming an angle of 30°-45°.

[0014] As a further improvement to the above scheme, the cross-section of the pipe is crown-shaped.

[0015] As a further improvement to the above solution, friction pads are attached to both sides of the track to ensure stable contact between the inspection robot's running wheels and the track.

[0016] As a further improvement to the above solution, the inspection robot's running wheels are made of polyurethane with a wear resistance coefficient of ≥0.8.

[0017] As a further improvement to the above solution, the surface of the inspection robot's running wheels is provided with anti-slip texture.

[0018] As a further improvement to the above solution, the power module of the inspection robot adopts a dual-power supply design.

[0019] As a further improvement to the above scheme, the included angle of the second air duct entering the protective cover at an angle ranging from 30° to 45°.

[0020] The second aspect of the present invention provides a dust prevention and high temperature resistance inspection system for coke oven basements, which includes an external control device. The system uses the aforementioned dust prevention and high temperature resistance inspection device for coke oven basements to collect the operating status of the basement equipment and transmits the collected information to the external control device.

[0021] As a further improvement to the above solution, the external control device includes: The control module, located in the external control equipment, is used to control the dust prevention and high-temperature resistance inspection equipment in the coke oven basement. The image recognition module, located in the external control device, is used to identify and automatically analyze the defects in the appearance of the equipment based on the information collected by the inspection robot, and to immediately mark any abnormalities detected. The alarm module, located in the external control device, is configured to issue an alarm signal after the image recognition module detects an abnormal situation.

[0022] (3) Beneficial effects 1. This invention designs a specific protective cover to protect inspection robots in the high dust concentration and high temperature environment of a coke oven basement. The protective cover is made of transparent polycarbonate, which has a temperature resistance range of -40℃ to 120℃, and is unaffected by the temperature inside the coke oven basement (the ambient temperature inside the coke oven basement is maintained at 40-60℃ year-round, and can reach above 70℃ in some areas due to heat dissipation from the equipment). Furthermore, the anti-static polishing treatment on both the inner and outer surfaces of this protective cover easily reduces the surface resistance to ≤10 Ω.9 The Ω design prevents dust from being electrostatically adsorbed and deposited on the protective cover surface. This design ensures that the cover's light transmittance remains unchanged even after electrostatic polishing, fully meeting the visual inspection requirements of the inspection robot. Furthermore, it allows for flexible splicing, enabling freedom in the size of the protective cover. The splicing points only require flange connections with built-in fluororubber sealing rings with an IP65 or higher sealing rating to ensure the sealed cavity formed by the protective cover and the substrate maintains extremely high sealing performance even in large coke oven basements. The sealed cavity is cooled by a cooling device (such as a variable frequency air conditioner, with the outdoor unit installed outside the coke oven basement and the indoor unit installed inside the sealed cavity), effectively dissipating the heat generated by the inspection robot's operation and the heat from heat conduction under high temperatures. Therefore, the coke oven basement dust-proof and high-temperature resistant inspection equipment of this invention solves the technical problem of existing technologies being unable to perform normal visual inspections in the complex environment of large areas, high dust concentrations, and high temperatures in coke oven basements.

[0023] 2. The high-temperature dust-proof inspection equipment for the coke oven basement of this invention uses two axial flow fans with master-slave linkage to balance the pressure inside the protective cover. Therefore, the inspection robot is less prone to issues such as wheel jamming, photosensitive element malfunction, and short circuits, and its service life is not reduced. This lowers the robot's failure rate, reduces the number of maintenance operations and spare parts replacements, and decreases the workload of manual maintenance. Simultaneously, the reduced maintenance time extends the robot's working time, significantly improving its inspection efficiency.

[0024] 3. The dust-proof and high-temperature resistant inspection equipment for the coke oven basement of the present invention ensures stable contact between the inspection robot's running wheel assembly and the track by attaching friction pads to both sides of the track surface.

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1 The coke oven basement dust prevention and high-temperature resistance inspection system described in this embodiment is used for visual inspection of equipment in a large-area, high-concentration dust and high-temperature environment within the coke oven basement. If any abnormalities are detected (such as corrosion, deformation, or breakage on the equipment surface), the system will issue a warning signal to remind staff to perform timely repairs. The coke oven basement dust prevention and high-temperature resistance inspection system includes coke oven basement dust prevention and high-temperature resistance inspection equipment and external control equipment 9.

[0031] Please see Figure 1The diagram shows a top-view view of a portion of the dust-proof and high-temperature-resistant inspection equipment for coke oven basements. This equipment is used for visual inspection of equipment within the large-area, high-concentration dust and high-temperature environment of a coke oven basement. The equipment includes a base plate 1, a track 2, an inspection robot 3, a protective cover 4, and a cooling system 5. It may also include multiple temperature sensors, two axial flow fans 6, a charging pile, a pressure relief device 8, and a pressure detection device 7. The base plate 1 is fixed to the ceiling of the coke oven basement. The track 2 is installed on the side of the base plate 1 away from the ceiling. The inspection robot 3 is mounted on the track 2 and can move along it to monitor the operation of the equipment installed in the coke oven basement. The protective cover 4 is also installed on the side of the base plate 1 away from the ceiling, but it forms a sealed cavity with the base plate 1 to house the track 2 and the inspection robot 3. The cooling system 5 is used to cool the sealed cavity.

[0032] Please combine Figure 2 This demonstrates the positional relationship between the inspection robot, protective cover 4, and base plate 1 within a sealed cavity. Pre-drilled holes are provided on base plate 1, through which the shank of a long expansion bolt passes. The top of the long expansion bolt is then bolted to an embedded steel plate in the basement ceiling via a connecting angle iron, providing a positioning base for the subsequent installation of track 2 and preventing its displacement. Two slots are located on the side of base plate 1 away from the ceiling, on either side of track 2, for installing the protective cover 4. The axial length of the two slots is the same as the axial length of base plate 1, allowing the protective cover 4 to completely cover the side of base plate 1 away from the ceiling after installation, thus fully accommodating track 2 and the inspection robot 3.

[0033] The track 2 can be an I-beam steel rail, fixed to the bottom side of the base plate 1. Friction pads 201 can be installed on both sides of the track 2 to increase the friction between the inspection robot 3 and the track 2, reducing the possibility of the inspection robot 3 derailing. In this embodiment, the track 2 and the base plate 1 are arranged in a ring, and the area where the track 2 and the base plate 1 are distributed can cover all the equipment in the basement, so that when the inspection robot 3 moves along the path set by the track 2, it can monitor the operation of all the equipment installed in the basement. At the same time, in some other embodiments, other types of tracks 2 can be used according to the distribution of the equipment installed in the basement, such as straight lines, curves, and U-shapes.

[0034] The overall shape of the protective cover 4 is determined by the base plate 1 and the track 2. In this embodiment, the protective cover 4 is an annular channel. The protective cover 4, specifically designed in this invention, provides the inspection robot 3 with a dust-proof working area with a temperature of 0-20℃, and also facilitates the charging and maintenance of the inspection robot 3. The annular protective cover 4 is composed of multiple semi-circular pipes spliced ​​together, with flange connections between the pipes and built-in fluororubber sealing rings, achieving a sealing rating of IP65, forming an integrally sealed protective cover 4 to completely isolate external dust. The top of the protective cover 4 has C-shaped grooves on both sides along the axial direction, and the openings of the grooves are all set to face outwards from the protective cover 4. The bottom protrusion of each guide rail is inserted into one of the grooves, so that the two guide rails clamp the protective cover 4, forming a sealed cavity with the base plate 1. The track 2 and the inspection robot 3 are both accommodated in this sealed cavity. The protective cover 4 is made of a high-temperature resistant and transparent material, such as polycarbonate, with a temperature range of -40℃ to 120℃ and a light transmittance of ≥90%, meeting the visual inspection requirements of the inspection robot 3. Both the inner and outer walls of the protective cover 4 are treated with anti-static polishing, resulting in a surface resistance of ≤10 Ω·cm. 9 Ω prevents dust from being electrostatically adsorbed and deposited. The diameter of the protective cover 4 is designed according to the size of the inspection robot 3, and is 100-150mm larger than the maximum range of the inspection robot 3 to allow for cold air circulation. The protective cover 4 has an inspection port, providing a window for personnel to inspect and maintain the inspection robot 3. The protective cover 4 also has an inspection plate that is movably connected to the inspection port via a snap-fit ​​mechanism, used to close or open the inspection port. The inspection plate is fixed with quick-release snaps. A sealing strip is installed around the inspection port to ensure a tight seal when closed. An emergency power interface and a data transmission interface can also be equipped on the inspection plate for easy equipment debugging and troubleshooting by maintenance personnel.

[0035] The cooling air device 5 continuously blows cold air into the protective cover 4 through an air duct 501 installed on the protective cover 4, thereby reducing the internal temperature of the protective cover 4. The cooling air device 5 can be an inverter air conditioner or a dry air cooler to control the temperature inside the sealed cavity. The air outlet of the cooling air device 5 faces the inside of the protective cover 4 in the same direction as the airflow, allowing the cold air to mix quickly with the air inside the duct. In some embodiments, an electrically adjustable air valve and a manual emergency valve can be installed at the connection between the air duct 501 and the protective cover 4 to achieve dual temperature control protection. The air duct 501 can be at an angle of 30°-45° to the protective cover 4 to allow the delivered cold air to enter the protective cover 4 smoothly. The air duct 501 can be made of stainless steel.

[0036] Multiple temperature sensors are evenly distributed within the protective cover 4 to collect the temperature inside. The amount of cold air delivered by the cooling air device 5 is adjusted based on the temperature sensors. If the temperature is too high, the amount of cold air delivered is reduced; if the temperature is too low, the amount of cold air delivered is increased, thereby maintaining the temperature inside the protective cover 4 between 0-20°C, providing the most suitable working environment for the inspection robot 3. In some other embodiments, the temperature sensors can be mounted on the inspection robot 3. The robot moves within the protective cover 4 to detect the temperature at various locations throughout the pipeline, thereby adjusting the temperature inside the protective cover 4 via the cooling air device 5.

[0037] It should be noted that the temperature sensor can be the IRFB series temperature sensor produced by Xi'an Gutai Sensor, which has a temperature measurement range of -20℃ to 400℃, fully covering the temperature sensor usage requirements in this embodiment.

[0038] The air ducts of the two axial flow fans 6 are connected to the protective cover 4 through flanges, and each is installed inside a bypass pipe. The circulating airflow of each axial flow fan 6 is obliquely introduced into the protective cover 4 through two air guide pipes 601, providing airflow power inside the protective cover 4. One axial flow fan 6 provides the main airflow power inside the protective cover 4, while the other axial flow fan 6 provides remote positive / negative pressure, forming a master-slave linkage to balance the pressure inside the protective cover 4.

[0039] Therefore, a sealed cavity is formed by the substrate 1 and the protective cover 4 to protect the track 2 and the inspection robot 3 from dust. Simultaneously, the combination of the cooling air device 5 and two axial flow fans 6 ensures the airtightness of the cavity while maintaining a preset temperature range. The inspection robot 3 moves within the sealed cavity along the pattern of the track 2, monitoring the operation of the equipment in the basement through the protective cover 4. The cooling air device 5 supplies cold air into the protective cover 4, and the two axial flow fans 6 fill the entire sealed cavity with cold air. Multiple temperature sensors monitor the temperature inside the sealed cavity in real time. When the temperature is too high, the amount of cold air supplied by the cooling air device 5 is increased to lower the temperature inside the sealed cavity; when the temperature is too low, the amount of cold air supplied by the cooling air device 5 is reduced to raise the temperature inside the sealed cavity.

[0040] On the one hand, the sealed cavity provides a dust-free working area for the inspection robot 3, with the temperature always maintained between 0-20℃. The inspection robot 3 will not come into direct contact with dust in this working area, avoiding equipment failure caused by dust jamming or short circuits. At the same time, the inspection robot 3 will always be in a suitable temperature of 0-20℃ in this working area, avoiding the high temperature environment from causing the inspection robot 3 to age faster and reduce the lifespan of circuit components, thus reducing the equipment failure rate and reducing the risk of fire and leakage of basement inspection equipment.

[0041] On the other hand, the reduced failure rate of inspection robot 3 reduces the number of times it needs to be repaired, thereby increasing its working time and significantly improving its inspection efficiency.

[0042] Pressure detection device 7 is located on the outer wall of protective cover 4 and is used to detect the air pressure inside protective cover 4. Pressure relief device 8 is located on the outer wall of protective cover 4 and is used to release the air pressure inside protective cover 4. The two form an interlocked control, which monitors and quickly releases abnormal pressure inside the sealed cover in real time, avoids damage to the equipment due to excessive pressure, and ensures stable operation of the equipment.

[0043] The charging pile is installed on the base plate 1 to charge the inspection robot 3 and detect the operation of the inspection robot 3; a fluororubber sealing baffle is installed around the charging docking end (i.e. the charging port) of the charging pile, and the sealing baffle is closed when not docked.

[0044] The inspection robot 3 moves along the track 2 within the sealed cavity between the protective cover 4 and the base plate 1 to monitor the operation of the basement equipment and record the data before transmitting it to the external control device 9. The inspection robot 3 generally includes an inspection host, a set of wheels, a data acquisition module, and a power module, and may also include a telescopic charging connector and positioning sensors.

[0045] It should be noted that the inspection robot 3 can be the T9-R model explosion-proof rail-mounted inspection robot 3 produced by Tianchuang Robotics. It is a rail-mounted inspection robot 3 and uses a dual-light gimbal (visible light + infrared thermal imaging) to collect data.

[0046] The running wheels can be made of wear-resistant material, and the surface can also be provided with anti-slip textures. The width of the track 2 is adapted to the running wheels of the inspection robot 3, allowing the running wheels to be connected and fixed to the friction plates 201 on both sides of the track 2, ensuring smooth movement of the robot along the track 2 and avoiding data distortion caused by bumps. In this embodiment, polyurethane with a wear resistance coefficient ≥0.8 can be selected as the wear-resistant material. In some other embodiments, other wear-resistant materials can be used as alternatives.

[0047] The data acquisition module monitors the operation of the basement equipment as the main inspection unit moves along track 2. Equipped with a high-definition infrared camera, it continuously collects image and location data of the basement equipment. The power module provides power to the various components of the inspection robot 3, employing a dual-power design for seamless switching and ensuring the continuity of inspection operations.

[0048] The telescopic charging connector is configured so that after the inspection robot 3 moves to the charging station, it aligns with the charging port of the charging station and extends / retracts, pushing the sealing baffle until the charging port is opened. This allows the telescopic charging connector to dock with the charging port for charging and to monitor the operation of the inspection robot 3. A positioning sensor provides precise positioning for the telescopic charging connector to align with the charging station and the location of the charging port within it.

[0049] It should be noted that the positioning sensor can be a high-precision displacement sensor, such as the Sensata LP35 SSI series or the Ametek GTE series, which can achieve a positioning accuracy of ±10 mm to ±100 mm, fully covering the requirements for the use of temperature sensors in this embodiment.

[0050] External control device 9 is used to regulate the dust-proof and high-temperature-resistant inspection equipment in the coke oven basement, ensuring its normal operation. Upon detecting any abnormalities (such as corrosion, deformation, or breakage on the equipment surface), it directly issues a warning signal to remind personnel to perform timely repairs. Please refer to [link / reference]. Figure 3 The external control device 9 may include a control module 901, an image recognition module 902, and an alarm module 903, and may also include a storage module 904.

[0051] The control module 901 is used to start or stop the cooling device 5, the two axial fans 6, the inspection robot 3, the charging pile, the pressure relief device 8, and the pressure detection device 7, enabling these devices to work together for inspection. The image recognition module 902 is used to identify and automatically analyze the appearance defects of the equipment installed in the basement, based on the image and location data collected by the acquisition module in the inspection robot 3, and immediately mark any abnormal data. The alarm module 903 is used to issue an alarm to alert personnel when the image recognition module 902 detects abnormal data. The alarm module 903 is also used to issue an alarm to alert personnel when a problem is detected in the inspection robot 3 via the charging pile. The storage module 904 is used to store data collected by multiple temperature sensors, the inspection robot 3, and the charging pile. It should be noted that the workflow of the inspection robot 3 is as follows: The external control device 9 issues inspection tasks according to a preset inspection plan (which can be set to 2-4 full-area inspections per day, or scheduled inspections of key areas). After receiving the command, the inspection robot 3's main unit starts the power module to provide power to the running wheels. The running wheels move at a constant speed along track 2, with the speed adjusted according to the inspection requirements. During the movement, the data acquisition module continuously collects image data and location data of the equipment installed in the basement and transmits it back to the external control device 9 in real time. The external control device 9 automatically analyzes the appearance defects (such as corrosion, deformation, and breakage) of the equipment installed in the basement through image recognition, immediately marking and uploading alarms upon detecting abnormal data. When the inspection robot 3's battery level drops below a preset value, it travels to the preset position of the charging pile according to the positioning sensor. The positioning sensor identifies the charging port and completes millimeter-level precise alignment. The telescopic charging connector automatically extends, opens the sealing baffle of the charging pile, and inserts into the charging port, achieving reliable electrode contact and initiating fast charging mode. After charging is complete, the connector automatically retracts, and the sealing baffle of the charging pile springs back and closes, restoring the charging pile to its sealed state. During charging, the detection station performs comprehensive status checks on the robot, including battery SOC, circuit system stability, sensor sensitivity, and wheel wear, generating an "Equipment Status Detection Report" which is then archived in the external control device 9. If any abnormalities are detected (such as battery SOC below 80%, sensor response delay, or wheel wear approaching a threshold), the inspection robot 3 sends an early warning signal to the external control device 9 and automatically adjusts the subsequent inspection plan to prevent the equipment from operating with faults.

[0052] Furthermore, when the power module of the inspection robot 3 malfunctions (e.g., power outage), the robot automatically switches power and navigates to the maintenance port based on positioning sensors, while simultaneously sending an emergency signal to the external control device 9. When an equipment abnormality is detected (e.g., wheel jamming, sensor malfunction), the robot pauses its inspection task, navigates to the maintenance port, and sends an emergency maintenance command. Maintenance personnel can view the robot's status data through the external control device 9 or directly observe the equipment through the transparent protective cover 4. If on-site repair is required, the movable inspection baffle can be opened for operation. The inspection baffle can also be equipped with an emergency power interface and a data transmission interface to facilitate equipment debugging and troubleshooting by maintenance personnel.

[0053] In summary, the specific process of this invention is as follows: I. Equipment Installation: To mark the installation position of track 2 on the roof slab of the coke oven basement, first install base plate 1, then fix I-beam track 2 on base plate 1. Next, lay transparent protective cover 4 on base plate 1 to complete flange splicing and sealing. Finally, install cooling air device 5, multiple temperature sensors, two axial flow fans 6, inspection robot 3, charging pile, pressure relief device 8, and pressure detection device 7.

[0054] II. Routine Inspection: The control module 901 in the external control device 9 issues inspection tasks according to the preset inspection plan (which can be set to 2-4 full-area inspections per day, or timed inspections of key areas). After receiving the instructions, the inspection robot 3 moves at a constant speed along the track 2, and the moving speed is adjusted according to the inspection requirements.

[0055] The inspection robot 3's data acquisition module continuously collects image data and location data of the basement equipment during its movement and transmits it back to the external control device 9 in real time. The system automatically analyzes the appearance defects of the equipment (such as corrosion, deformation, and breakage) through image recognition, and immediately marks and uploads alarms when abnormal data is detected.

[0056] The cooling air unit 5 automatically adjusts the air supply volume based on real-time data from multiple temperature sensors inside the duct, using a program set by the external control device 9, to maintain the duct temperature between 0-20℃. Two axial flow fans 6 operate continuously to ensure air circulation within the duct, and together with the anti-static polished protective cover 4, ensure that visual inspection is not affected by dust obstruction.

[0057] III. Charging and Status Monitoring: After completing a single inspection task, the inspection robot 3 automatically travels to the charging station using positioning sensors, completes the charging connection, and starts fast charging mode.

[0058] During the charging process, the charging pile performs a comprehensive status check on the inspection robot 3, including battery SOC, circuit system stability, sensor sensitivity, and wear of the running wheels, and generates an "equipment status check report", which is then archived in the external control device 9.

[0059] If an abnormal situation is detected (such as battery SOC below 80%, sensor response delay, wear of running wheels approaching the threshold, etc.), the external control device 9 will not only send an early warning signal, but also automatically adjust the subsequent inspection plan to avoid the equipment from operating with a fault.

[0060] IV. Emergency Response When the inspection robot 3 experiences a power failure (such as a power outage), the robot automatically switches to a new power source, travels to the maintenance port, and sends an emergency signal to the external control device 9.

[0061] When an equipment malfunction is detected (such as wheel jamming, sensor failure, etc.), the robot suspends its inspection task, moves to the maintenance port, and sends an emergency maintenance command.

[0062] Maintenance personnel can view the robot's status data through external control device 9, or directly observe the equipment through transparent protective cover 4. If on-site repair is required, the movable inspection panel can be opened for operation. The inspection panel can also be equipped with an emergency power interface and a data transmission interface to facilitate equipment debugging and troubleshooting by maintenance personnel.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
