The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0032] Example:
[0033] Referring to Figures 1-5, this embodiment provides an inspection robot, including:
[0034] The traveling mechanism 5 includes traveling wheels 5.1, guide wheels 5.2, load-bearing wheels 5.3, and a traveling frame 5.5. The traveling frame 5.5 is provided with pairs of guide wheels 5.2 and pairs of load-bearing wheels 5.3 at both ends, and pairs of traveling wheels 5.1 in the middle. The pairs of guide wheels 5.2, load-bearing wheels 5.3, and traveling wheels 5.1 are distributed on both sides of the guide rail 1. The guide wheels 5.2 and traveling wheels 5.1 are in rolling contact with the side of the web plate 1.2 of the guide rail 1, and the load-bearing wheels 5.3 are in rolling contact with the upper surface of the lower flange plate 1.3 of the guide rail 1.
[0035] The main frame 9 is mounted on the walking mechanism 5 and has an electrical control device 11 inside it;
[0036] The monitoring device 8 is mounted on the main frame 9 and is electrically connected to the electrical control device 11.
[0037] Specifically, in this embodiment, the walking frame 5.5 is provided with two pairs of guide wheels 5.2 and a pair of load-bearing wheels 5.3 at one end, wherein the load-bearing wheels 5.3 are located between the two pairs of guide wheels 5.2. In this embodiment, the movement of the inspection robot is guided by the guide wheels 5.2 rolling along the side of the web plate 1.2 of the guide rail 1, the walking wheels 5.1 provide the driving force for the inspection robot to walk, and the load-bearing wheels 5.3 transfer the weight of the inspection robot to the guide rail 1. Furthermore, the wheel surface of the walking wheels is knurled to increase the friction between the walking wheels and the web plate of the guide rail.
[0038] As shown in Figure 2, the guide rail 1 in this example includes an upper flange plate 1.1, a web plate 1.2, and a lower flange plate 1.3. The upper flange plate and the lower flange plate are arranged in parallel and the web plate 1.2 is provided between them. The upper flange plate 1.1, the web plate 1.2, and the lower flange plate 1.3 form an I-shape. The upper flange plate 1.1 can be connected to structural components such as brackets to lift the entire guide rail 1.
[0039] As shown in Figures 1-3, the walking mechanism 5 further includes a drive device 5.4, a guide shaft 5.6, a spring 5.7, and a floating limiter 5.8. Guide shafts 5.6 and drive devices 5.4 are provided on both sides of the walking frame 5.5. The drive device 5.4 is slidably mounted on the guide shaft 5.6, and its output shaft is connected to the walking wheel 5.1 on the same side. A floating limiter 5.8 is provided at the end of the guide shaft 5.6 away from the walking frame 5.5. A compressed spring 5.7 is fitted on the guide shaft 5.6, with both ends of the spring 5.7 pressing against the floating limiter 5.8 and the drive device 5.4, respectively. The drive device can slide along the length of the guide shaft with the walking wheel 5.1. The spring provides elasticity to keep the walking wheel 5.1 in close contact with the side of the web plate, thus enabling the walking wheel 5.1 to float in a direction perpendicular to the side of the web plate during the inspection robot's movement, preventing slippage and meeting the requirements for turning and climbing.
[0040] Preferably, in this embodiment, two guide shafts 5.6 are arranged parallel to each other on one side of the walking frame 5.5. The two sides of the drive device 5.4 are slidably mounted on the two guide shafts 5.6 via sliders, thereby ensuring that the drive device can slide smoothly along the length direction of the guide shafts. Further, the drive device includes a mounting housing and a rotary drive component disposed inside the mounting housing. The rotary drive component is fixedly mounted on the mounting housing, and the output shaft of the rotary drive component is connected to the walking wheel 5.1. The mounting housing is slidably mounted on the guide shafts 5.6 via sliders. The rotary drive component is preferably a planetary geared servo motor.
[0041] Preferably, the floating limiting member 5.8 is a limiting nut, and the end of the guide shaft is provided with an external thread. The limiting nut is threadedly connected to the guide shaft 5.6. By turning the limiting nut, the compression degree of the spring can be adjusted, thereby adjusting the elastic force of the spring acting on the drive device, that is, adjusting the pressure of the traveling wheel acting on the side of the web plate.
[0042] Preferably, in this embodiment, the two guide shafts 5.6 located on both sides of the walking frame 5.5 and coaxially arranged are integral shafts. These shafts are movably connected through the walking frame 5.5, meaning a single shaft movably connects through a through-hole in the walking frame 5.5. Part of this shaft is on the left side of the walking frame 5.5, part is located in the through-hole, and the remaining part is located on the right side. With this arrangement, only the limiting nut on one side needs to be adjusted to adjust the pressure of the two pairs of walking wheels acting on the side of the web, improving the adjustment efficiency for the two walking wheels. In some embodiments, the guide shafts 5.6 on both sides of the walking frame 5.5 may not be integral structures; that is, the guide shafts on both sides may be fixedly mounted on the walking frame 5.5. This structural form can also achieve the effect of floating walking wheels.
[0043] As shown in Figures 1, 4, and 5, the main frame 9 houses a battery 10 for power supply. A wireless charging receiver 6 is mounted on the main frame 9 and connected to the battery 10. A wireless charging transmitter 4 is mounted on the guide rail 1. The wireless charging receiver 6 and the wireless charging transmitter 4 cooperate to charge the battery 10. Preferably, the wireless charging transmitter 4 is mounted on the guide rail 1 via a transmitter mounting bracket 3. Specifically, in this embodiment, the wireless charging receiver 6 is located at the end of the main frame 9 near the starting point, and the wireless charging transmitter 4 is located at the starting point of the guide rail 1. Therefore, charging can be performed when the inspection robot moves to the starting point of the guide rail 1. Alternatively, in some embodiments, the wireless charging receiver 6 may be located on the side of the main frame 9, and the wireless charging transmitter 4 may also be located on the side of the guide rail, on the same side as the wireless charging receiver 6. This arrangement also achieves the purpose of charging the battery.
[0044] Referring to Figure 1, the guide rail 1 is equipped with end limiters 2 and magnets (not shown) at both the starting and ending points. The main frame 9 is equipped with at least one position sensor 12, which senses the magnet to identify the position of the inspection robot. By sensing the magnet, the position sensor 12 determines that the inspection robot has reached the end of the guide rail. Based on the signal from the position sensor, the inspection robot can be controlled to stop. The end limiters 2 are used to hard limit the movement of the inspection robot. Preferably, the position sensor 12 is a Hall sensor. In this embodiment, there are two position sensors. When the first position sensor senses the magnet, it can control the inspection robot to decelerate; when the second position sensor senses the magnet, it can control the inspection robot to stop. Simultaneously, the cooperation between the position sensors and the magnets can also eliminate the cumulative motion error of the inspection robot. For example, when the inspection robot is stopped based on the signal from the position sensor, the robot's travel distance is simultaneously reset to zero.
[0045] As shown in Figure 1, both ends of the main frame 9 are equipped with anti-collision components 7. Each anti-collision component 7 includes a pressure-sensitive device and a flexible protective layer disposed on the surface of the pressure-sensitive device. The pressure-sensitive device is electrically connected to the electronic control device 11. The flexible protective layer in the anti-collision component 7 is used to prevent rigid contact when the inspection robot collides with people or objects. The pressure-sensitive device transmits a signal to the electronic control device 11 when it detects pressure, thereby controlling the inspection robot to stop and protecting the safety of equipment and personnel.
[0046] Referring to Figures 4 and 5, the electrical control device 11 includes a PLC controller 11.4 and a wireless communication module 11.7. The monitoring device 8, the wireless communication module 11.7, the position sensor 12, and the pressure-sensitive device are all connected to the PLC controller 11.4. Further, the electrical control device 11 also includes a fuse 11.1 and a terminal block 11.2. The terminal block 11.2 is used to connect circuits, and the fuse 11.1 is used to limit the maximum current in the circuit. Preferably, in this embodiment, the fuse 11.1, terminal block 11.2, PLC controller 11.4, and wireless communication module 11.7 are all mounted on the inner wall of the main frame 9 via mounting rails 11.3. In this embodiment, the mounting rails 11.3 are preferably DIN-35 rails.
[0047] Furthermore, the electronic control device 11 also includes an emergency stop button 11.5 and an indicator light 11.6. Both the emergency stop button 11.5 and the indicator light 11.6 are connected to the PLC controller 11.4. There are multiple indicator lights 11.6, which use different colors to indicate the working status of the inspection robot. The emergency stop button 11.5 is used to stop the operation of the inspection robot in the event of an emergency.
[0048] Preferably, the surface of the main frame 9 is provided with a heat sink 13 and an antenna 14, wherein the antenna 14 is connected to the wireless communication module 11.7 to realize the reception and transmission of data information, and the heat sink 13 is used to dissipate heat from the electronic control device 11.
[0049] Preferably, the monitoring device 8 includes a camera that can rotate 360 degrees and adjust its pitch. The camera collects image information to analyze the state of the monitored object.
[0050] Preferably, the wireless communication module 11.7 in this embodiment is preferably a USR-W660 wireless client; the battery 10 is preferably a lithium battery with 485 communication; the monitoring device 8 is preferably a Hikvision HM-TD5728T-7 micro-carrier gimbal. In this embodiment, the monitoring device 8 can set temperature thresholds, over-temperature alarms, maximum temperature crosshair positioning, full-screen temperature acquisition, thermal image acquisition, etc., and supports automatic aperture, automatic focus, automatic white balance, backlight compensation, wide dynamic range, 3D digital noise reduction, day and night switching, power failure memory, deep learning intelligent functions, etc.
[0051] In this embodiment, the monitoring device 8 acquires video streams of the surrounding environment and combines them with the YOLO (You Only Look Once) target detection algorithm to automatically identify the instrument lights (red, yellow, green) and cabinet door opening / closing status of the monitored object. When a red light or cabinet door opening is detected, an alarm is generated. At the same time, the detected video stream is returned via WebSocket for remote monitoring and processing.
[0052] The inspection robot in this embodiment can automatically perform inspections at predetermined time intervals, capturing real-time video streams of the surrounding environment through a camera; it analyzes the acquired video streams in real time using the YOLO algorithm to identify equipment instrument lights (red, yellow, green) and cabinet door status (open / closed) in the images; when a red light or cabinet door is detected, an alarm is generated, which can be equipment status information or alert inspection personnel through audible and visual alarms or other means; via the WebSocket protocol, the processed video stream with tags is returned to the remote monitoring platform in real time, allowing users to view the video stream and related alarm information in real time; after completing the alarm, the inspection robot will resume normal inspection status and continue to perform subsequent inspection tasks.
[0053] The inspection robot in this embodiment, combined with a target detection algorithm, achieves fully automated equipment inspection, avoiding omissions and delays caused by manual inspections. Automated inspections and real-time alarms effectively improve work efficiency, reduce human error, and enhance equipment management security. The inspection robot in this embodiment uses the YOLO algorithm to analyze equipment status in real time, efficiently and accurately identifying the status of equipment instrument lights and cabinet doors, promptly detecting equipment faults or anomalies.
