Description

Technical Field

[0001] This utility model relates to the field of intelligent inspection technology for power equipment, specifically an intelligent inspection device for thermal power plants. Background Technology

[0002] As a core energy production facility, the operating status of equipment in thermal power plants, such as boiler temperature, pipeline sealing, concentration of harmful gases in the workshop, and environmental parameters such as temperature and humidity, directly affects production safety and efficiency. Therefore, high-frequency inspections are necessary to achieve comprehensive monitoring.

[0003] Currently, traditional thermal power plant inspections are usually done manually. However, thermal power plant workshops are characterized by high temperatures, high dust levels, and dense equipment. Manual inspections are inefficient and pose safety risks such as working at heights and burns. In addition, manual inspections rely on experience and judgment, making it difficult to accurately quantify parameters such as temperature and gas concentration. Furthermore, they cannot simultaneously correlate multi-dimensional data such as equipment appearance defects, ambient temperature and humidity, and harmful gas concentrations, which can easily lead to the omission of potential faults.

[0004] To address the shortcomings of manual inspections, existing technologies have gradually developed intelligent inspection devices, such as the power monitoring and inspection device disclosed in patent number CN202122792754.3. This device integrates laser detectors, one-way cameras, temperature and humidity sensors to monitor some parameters. However, when adapting to the complex scenarios of thermal power plants, such devices cannot simultaneously confirm whether there is a leak of harmful gases or cracks in the equipment's appearance. The anti-collision protection design of each sensor is lacking, and the temperature and humidity sensor probes, infrared temperature measurement camera lenses, and gas detection sensor inlets are easily damaged by impacts. Once the sensors are damaged, the multivariable measurement function of the entire device will partially fail, requiring frequent shutdowns for maintenance and affecting the continuity of inspections.

[0005] Furthermore, the sensor layout and anti-collision structure of existing integrated devices lack compatible design. Although some anti-collision structures (such as metal protective covers) can play a protective role, they may block the detection angle of infrared temperature measurement cameras, hinder the transmission of distance measurement signals from ultrasonic sensors, or block the air intake channel of gas detection sensors. This will reduce the measurement accuracy and coverage of each sensor and fail to meet the stringent requirements of thermal power plants for the accuracy of inspection data. Utility Model Content

[0006] The purpose of this utility model is to provide an intelligent inspection device for thermal power plants, which has the advantages of being able to simultaneously and accurately monitor multi-dimensional parameters, equipped with a suitable sensor anti-collision protection structure to ensure measurement accuracy and coverage, adopting a modular sensor design to maintain inspection continuity, and being able to replace manual labor to reduce risks and improve detection efficiency, thus solving the problems in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A smart inspection device for a thermal power plant includes a carrier, a moving mechanism disposed at the lower end of the carrier, a vertical plate fixed to the upper end of the carrier, a battery fixed to the upper end of the carrier, a control component fixed to the vertical plate, a guide rail fixed to the side wall of the vertical plate, a slider slidably disposed on the guide rail, a carrier plate fixed to the side wall of the slider, a second driving mechanism disposed at the upper end of the carrier plate, a U-shaped frame disposed at the moving end of the second driving mechanism, rotating blocks rotatably mounted on both sides of the U-shaped frame, a protective mechanism disposed at the upper end of the rotating blocks, and a locking mechanism disposed on the U-shaped frame for locking the rotating blocks onto the U-shaped frame.

[0008] The sidewall of the guide rail is provided with a first drive mechanism for moving the slider; The U-shaped frame is equipped with an inspection assembly, which includes a second fixed block fixed to the side wall of the U-shaped frame, four rotating columns rotatably mounted on the upper end of the second fixed block, and a third drive mechanism set at the lower end of the second fixed block for driving the rotating columns to rotate. The side walls of the four rotating columns are respectively fixed with a first fixed plate, a second fixed plate, a third fixed plate, and a fourth fixed plate. A temperature and humidity sensor is fixed to the first fixed plate, an infrared temperature sensor is fixed to the second fixed plate, a gas detection sensor is fixed to the third fixed plate, and an appearance inspection camera is fixed to the fourth fixed plate. A camera assembly is also installed at the upper end of the upright plate, and ultrasonic ranging sensors are fixed to the ends of the two second fixed blocks that are far apart from each other.

[0009] Preferably, the moving mechanism includes multiple supports fixed to the side wall of the carrier and rollers rotatably mounted on the supports.

[0010] It is worth noting that the mobile mechanism is fixed to the carrier through multiple supports, which can improve the overall support stability, and the rotation design of the rollers can enable the device to move flexibly within the thermal power plant.

[0011] Preferably, the control components include a controller and a wireless transceiver fixed to the side wall of the upright plate.

[0012] It is worth noting that the controller can centrally receive data from various detection components such as temperature and humidity sensors and infrared temperature sensors, realize data integration and logical judgment, and promptly identify faults such as abnormal temperature and humidity and excessive temperature in thermal power plant equipment. The wireless transceiver can remotely transmit the detection data to the back-end terminal and receive back-end control commands to realize remote operation of the device. This eliminates the need for personnel to enter the high-temperature and high-risk thermal power plant equipment area, improves the safety of inspections, and facilitates real-time monitoring of inspection progress and equipment status by the back-end, shortening fault response time.

[0013] Preferably, the first drive mechanism includes a first electric cylinder fixed to the side wall of the guide rail and a connecting block fixed to the output shaft of the first electric cylinder, wherein the side wall of the connecting block is fixed to the side wall of the slider.

[0014] It is worth noting that the first electric cylinder can drive the connecting block and slider to move stably along the guide rail through the extension and retraction of the output shaft, thereby adjusting the height of the bearing plate and inspection components, avoiding blind spots caused by fixed height, and the electric cylinder drive has no mechanical wear risk, runs stably, and can adapt to the high temperature and dust conditions of thermal power plants for a long time, ensuring the reliability and accuracy of height adjustment.

[0015] Preferably, the second drive mechanism includes a second electric cylinder fixed to the upper end of the support plate and a first L-shaped block fixed to the output shaft of the second electric cylinder, with the output ends of the two second electric cylinders facing each other.

[0016] It is worth noting that the two opposing second electric cylinders can extend and retract through their output shafts, causing the first L-shaped block and the U-shaped frame to move closer or further apart synchronously, thereby adjusting the spacing between the U-shaped frames. This design can adapt to the inspection needs of equipment of different sizes in thermal power plants (such as pipes of different sizes and valves of different sizes), allowing the inspection components to be close to the inspection target and improving the accuracy of temperature, humidity, and other detection data.

[0017] Preferably, the protective mechanism includes multiple fixed seats fixed to the upper end of the rotating block, a fixed column fixed to the inner wall of the fixed seat, and a rubber pad fixed to one end of the fixed column.

[0018] It is worth noting that the fixed base and fixed column can limit and fix the surrounding components of the inspection component, preventing the components from shifting due to vibration during the operation of the thermal power plant equipment. The rubber pad has elastic buffering performance, which can prevent foreign objects from hitting the device and prevent precision components such as temperature and humidity sensors and appearance inspection cameras from being damaged by collisions with foreign objects. At the same time, the rubber pad can prevent the fixed column from directly contacting the detection component and causing scratches, protecting the appearance and functional integrity of the component, extending the service life of the device, and adapting to the high-frequency vibration conditions of thermal power plants.

[0019] Preferably, the third drive mechanism includes two second L-shaped blocks fixed to the lower end of the second fixed block, a bearing frame fixed to one end of the two second L-shaped blocks close to each other, a toothed ring fixed to the side wall of the rotating column, a synchronous belt disposed on the upper end of the bearing frame, a support base fixed to the lower end of the second fixed block, and a motor fixed to the upper end of the support base. The upper end of the output shaft of the motor is fixed to the lower end of one of the rotating columns, and the side walls of the four toothed rings are all engaged with the bearing frame.

[0020] It is worth noting that the motor drives a single rotating column to rotate through the output shaft, and then through the gear ring and synchronous belt transmission, the four rotating columns rotate synchronously. This allows the four detection components, such as the temperature and humidity sensor, to switch detection angles or positions synchronously. The second L-shaped block and the support frame form a stable support to ensure the accuracy of the synchronous belt transmission. The support base improves the stability of the motor installation and avoids the impact of the high temperature environment of the thermal power plant on the motor operation. The synchronous rotation design ensures that the detection angles of each detection component are consistent, which facilitates data comparison and analysis and improves the accuracy of fault diagnosis.

[0021] Preferably, the camera assembly includes a top plate fixed to the upper end of the upright plate, a first fixing block fixed to the upper end of the top plate, and a visual inspection camera fixed to the side wall of the first fixing block.

[0022] It is worth noting that the top plate raises the installation height of the visual inspection camera, expands the monitoring field of view, and can cover a larger area around the carrier. The first fixing block can stabilize the position of the camera, prevent the camera from shaking due to device movement, and ensure clear images.

[0023] Preferably, the locking mechanism includes a threaded post threaded through the U-shaped frame and the rotating block, and two nuts threaded onto the side wall of the threaded post, the two nuts being used to lock the threaded post onto the U-shaped frame.

[0024] It is worth noting that the threaded column passes through the U-shaped frame and the rotating block, and with the double locking of the two nuts, a firm connection between the rotating block and the U-shaped frame can be achieved. The threaded connection structure is easy to disassemble. When maintenance or replacement of the inspection component is required, the component can be separated simply by unscrewing the nuts, making the operation convenient.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model effectively solves the problems of high safety risks, low efficiency and data lag in traditional manual inspection by setting up a moving mechanism and control components. The moving mechanism can drive the device to move automatically in the thermal power plant without personnel entering high-risk areas with high temperature and dust. The control components can centrally receive data from each detection component and remotely transmit it to the backend through a wireless transceiver. At the same time, it can receive control commands from the backend to realize remote operation. This not only eliminates the safety hazards of manual exposure, but also allows the backend to monitor the inspection progress and equipment status in real time, quickly identify faults and shorten response time. 2. This utility model solves the problems of missing multi-dimensional monitoring and sensor fragility in existing intelligent devices by setting up a patrol component and a protective mechanism: The patrol component integrates temperature and humidity, infrared temperature measurement, gas detection and appearance inspection functions, and can realize synchronous adjustment of the angle of each detection component with the third drive mechanism to achieve synchronous and accurate monitoring of multi-dimensional parameters; The protective mechanism uses elastic rubber pads to buffer impacts and limit and fix components to avoid sensor damage due to vibration and collision, ensuring the continuous effectiveness of the device's multi-variable measurement function, eliminating the need for frequent shutdowns for maintenance, and maintaining the continuity of inspection.

[0026] 3. This utility model solves the problems of existing anti-collision structures affecting detection accuracy and inconvenience in maintenance by optimizing the design of the protective mechanism and setting the locking mechanism. The rubber pad design of the protective mechanism will not block the view of the infrared temperature measurement camera, obstruct the ultrasonic ranging signal, or block the air intake channel of the gas detection sensor, ensuring the measurement accuracy and coverage of each sensor. The locking mechanism adopts a threaded column and double nut cooperation, and the components can be separated by simply unscrewing the nuts during disassembly, which facilitates the maintenance of the protective mechanism and can further adapt to the stringent requirements of thermal power plants for the accuracy of inspection data and maintenance efficiency.

[0030] To address the shortcomings of existing technologies, such as low efficiency, high safety risks, difficulty in accurately quantifying parameters, and inability to synchronously correlate multi-dimensional data during manual inspections, as well as the inability of existing intelligent inspection devices to simultaneously monitor hazardous gas leaks and equipment surface cracks, the lack of sensor anti-collision protection leading to inspection interruptions, and the incompatibility between anti-collision structures and sensor layouts reducing measurement accuracy and coverage, the following technical solutions are proposed. Please refer to [link / reference].

[0031] The side wall of the guide rail 4 is provided with a first drive mechanism for moving the slider 5; The U-shaped frame 7 is equipped with an inspection assembly, which includes a second fixed block 15 fixed to the side wall of the U-shaped frame 7, four rotating columns 16 rotatably mounted on the upper end of the second fixed block 15, and a third drive mechanism set at the lower end of the second fixed block 15 for driving the rotating columns 16 to rotate.

All electrical devices are electrically connected to the control component. The use of the appearance inspection camera to capture images of the product appearance and transmitting the data to the server for processing and analysis via the control component is existing technology and will not be described in detail here.

[0033] In this embodiment, specifically: the moving mechanism 2 includes multiple brackets 201 fixed to the side wall of the carrier 1 and rollers 202 rotatably mounted on the brackets 201.

[0034] In this embodiment, specifically: the control components include a controller 31 and a wireless transceiver 32 fixed to the side wall of the upright plate 3.

[0035] In this embodiment, specifically: the first driving mechanism includes a first electric cylinder 41 fixed to the side wall of the guide rail 4 and a connecting block 42 fixed to the output shaft of the first electric cylinder 41, and the side wall of the connecting block 42 is fixed to the side wall of the slider 5.

[0036] In this embodiment, specifically: the second driving mechanism includes a second electric cylinder 61 fixed to the upper end of the support plate 6 and a first L-shaped block 62 fixed to the output shaft of the second electric cylinder 61, with the output ends of the two second electric cylinders 61 facing each other.

[0037] In this embodiment, the protective mechanism specifically includes multiple fixed seats 9 fixed to the upper end of the rotating block 8, a fixed column 10 fixed to the inner wall of the fixed seat 9, and a rubber pad 11 fixed to one end of the fixed column 10.

[0038] In this embodiment, specifically: the third drive mechanism includes two second L-shaped blocks 17 fixed to the lower end of the second fixed block 15, a bearing frame 18 fixed to one end of the two second L-shaped blocks 17 close to each other, a toothed ring 19 fixed to the side wall of the rotating column 16, a synchronous belt 20 disposed on the upper end of the bearing frame 18, a support base 1501 fixed to the lower end of the second fixed block 15, and a motor 1502 fixed to the upper end of the support base 1501. The upper end of the output shaft of the motor 1502 is fixed to the lower end of one of the rotating columns 16, and the side walls of the four toothed rings 19 are all engaged with the bearing frame 18.

[0039] In this embodiment, specifically: the camera assembly includes a top plate 12 fixed to the upper end of the upright plate 3, a first fixing block 13 fixed to the upper end of the top plate 12, and a visual inspection camera 14 fixed to the side wall of the first fixing block 13.

[0040] In this embodiment, specifically: the locking mechanism includes a threaded post 26 that is threaded through and threaded onto the U-shaped frame 7 and the rotating block 8, and two nuts 27 that are threaded onto the side wall of the threaded post 26. The two nuts 27 are used to lock the threaded post 26 onto the U-shaped frame 7.

[0041] Working principle: First, before the device is started, it is necessary to confirm that the battery fixed to the upper end of the carrier 1 is fully charged. The battery provides power support for all electrical equipment in the device. Each electrical device is electrically connected to the control component fixed to the side wall of the vertical plate 3. The control component includes a controller 31 and a wireless transceiver 32 fixed to the side wall of the vertical plate 3. When the device is moved, the carrier 1 can be manually pushed or pulled by external power machinery, causing the rollers 202, which are fixed to multiple supports 201 on the side wall of the carrier 1, to rotate and roll, thereby moving the entire device within the thermal power plant without requiring personnel to enter high-risk areas. When it is necessary to adjust the horizontal position of the inspection component, the first drive mechanism fixed to the side wall of the guide rail 4 is activated. The output shaft of the first electric cylinder 41 extends and retracts, driving the connecting block 42 to move. The slider 5 fixed to the side wall of the connecting block 42 slides on the guide rail 4 fixed to the side wall of the vertical plate 3. The bearing plate 6 fixed to the side wall of the slider 5 moves synchronously, thereby driving the components on the bearing plate 6 to move. Next, the second drive mechanism fixed to the upper end of the support plate 6 is activated. The output ends of the two second electric cylinders 61 extend and retract towards each other, driving the first L-shaped block 62 to move. The U-shaped frame 7 connected to the first L-shaped block 62 moves accordingly, realizing the precise position adjustment of the inspection component in the horizontal direction. When the inspection component is working, the motor 1502 fixed to the lower support base 1501 of the second fixed block 15 is started first. The output shaft of the motor 1502 drives one of the rotating columns 16 fixed to it to rotate. The toothed rings 19 fixed to the side wall of the rotating column 16 rotate synchronously. The toothed rings 19 on the side walls of all four rotating columns 16 mesh with the synchronous belt 20 set on the upper end of the bearing frame 18. The synchronous belt 20 drives the other three toothed rings 19 and the corresponding rotating columns 16 to rotate synchronously. The rotating columns 16 respectively drive the first fixed plate 22, the second fixed plate 23, the third fixed plate 24, and the fourth fixed plate 25 fixed to their side walls to rotate, thereby adjusting the angle of the temperature and humidity sensor on the first fixed plate 22, the infrared temperature sensor on the second fixed plate 23, the gas detection sensor on the third fixed plate 24, and the appearance inspection camera on the fourth fixed plate 25 to achieve multi-dimensional parameter monitoring. At the same time, the ultrasonic ranging sensor 21 fixed to the two second fixed blocks 15 at opposite ends detects the distance between the device and the surrounding equipment in real time to avoid collision. In addition, the visual inspection camera 14 is activated simultaneously to assist in capturing images of the surrounding environment and the appearance of the equipment; Data collected by various sensors (temperature and humidity sensor, infrared temperature sensor, gas detection sensor, appearance inspection camera, ultrasonic ranging sensor 21, and visual inspection camera 14) is transmitted to the controller 31 in real time. After preliminary processing of the data, the controller 31 transmits it remotely to the back-end server via the wireless transceiver 32. Back-end staff can view the inspection progress and equipment status through the server. If remote control of the device is required, the back-end command is transmitted to the controller 31 via the wireless transceiver 32, and the controller 31 controls the operation of each drive mechanism (first drive mechanism, second drive mechanism, and third drive mechanism) and the sensors. During device operation, the rubber pad 11 in the protective mechanism plays a protective role, preventing damage to the sensors when the device moves or collides through elastic buffering, and ensuring the continuous effectiveness of the multivariable measurement function; When maintenance of the protective mechanism is required, unscrew the two nuts 27 to remove the threaded post 26 from the U-shaped frame 7 and the rotating block 8, separating the rotating block 8 from the U-shaped frame 7 for easy maintenance of the protective mechanism. After maintenance, re-pass the threaded post 26 through the U-shaped frame 7 and the rotating block 8, and tighten the two nuts 27 to lock it in place, ensuring the stable operation of the device in the future.
