Description

Technical Field

[0001] This utility model relates to the field of hazardous materials identification technology, and in particular to a vision-based hazardous materials leakage identification device. Background Technology

[0002] In the complex environment of power plants, characterized by high temperature, high humidity, and strong electromagnetic interference, hazardous chemicals are diverse and widely distributed. Traditional online monitoring equipment for hazardous materials is mostly fixedly installed and relies on temperature, humidity, and gas-sensitive sensors for detection. This not only makes it difficult to capture early warning information that is readily visible, such as seepage from tank surfaces or initial fumes, but often only detects the problem after a large amount of harmful gas has dissipated and spread over a wide area, resulting in a significant delay in emergency response. Furthermore, it is easily affected by environmental factors, leading to inaccurate detection data, and it is difficult to quickly seal off the leak source after it is detected. The closest prior art to this patent is the online monitoring system for hazardous chemicals with publication number CN221323971U. The monitoring and detection equipment, although it adjusts the position of the detection probe through a rotating mechanism on the top of the central support box of the placement platform and a lifting mechanism in the sealed box at the bottom of the placement platform to improve the limitations of fixed installation of traditional equipment, still has height limitations. It is difficult to detect hazardous chemical gases accumulated at higher positions or near the ceiling. Environmental interference factors also have a significant impact on its detection results. Temperature, humidity, airflow, etc., can easily lead to inaccurate detection data or false positives and false negatives. At the same time, it is not sufficient to respond to sudden rapid leaks. The rotating and lifting mechanisms require a certain amount of time to operate, making it difficult to complete the detection operation in the shortest possible time in the large environment of a power plant, which can easily lead to the rapid spread of a large number of harmful substances. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a vision-based hazardous material leakage identification device for detecting and identifying hazardous material leakage in a factory environment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vision-based hazardous material leakage identification device, including a trolley, a rotating gimbal on the trolley, a horizontally arranged connecting cylinder fixed on the rotating gimbal, a camera and an infrared thermal imager rotatably connected to both ends of the connecting cylinder, and motors for driving the camera and the infrared thermal imager to rotate at both ends of the connecting cylinder.

[0005] Preferably, the trolley is equipped with a control box, and a controller is installed inside the control box. The camera and infrared thermal imager are electrically connected to the input terminal of the controller.

[0006] Preferably, the trolley is equipped with an audible and visual alarm, which is electrically connected to the output of the controller.

[0007] Preferably, the audible and visual alarm is mounted on a column.

[0008] Preferably, the controller uses an ESP32 chip with a built-in Wi-Fi module, which wirelessly connects to the control center. The Wi-Fi module is also connected to an antenna.

[0009] Preferably, a cleaning device is provided below the camera and the infrared thermal imager. The cleaning device includes a rotating motor, a turntable is provided at the upper end of the rotating motor, and a cleaning module is provided on the turntable. The cleaning module is a sponge block or a brush.

[0010] Preferably, the outer side of the vehicle wheels is provided with a barrier, and an anti-collision layer is provided on the outer side of the barrier.

[0011] Preferably, the anti-collision layer is a rubber layer.

[0012] Preferably, the front end of the vehicle is equipped with headlights.

[0013] This invention provides a vision-based hazardous materials leakage identification device, which has the following advantages: 1. Enhanced detection flexibility and coverage: The device uses a mobile trolley as a carrier, and is equipped with a rotating gimbal and cameras and infrared thermal imagers that can be rotated by motors at both ends of the connecting cylinder. It can flexibly adjust the detection angle and position, breaking through the height limitations of traditional fixed equipment and similar technologies. It can effectively capture early visual warning information such as liquid seepage and initial smoke on the surface of the tank, covering different areas of the power plant at different elevations, and solving the problem of narrow detection range and difficulty in capturing early hidden dangers of traditional equipment.

[0014] 2. Ensure the stability and accuracy of detection: On the one hand, the visual detection method of combining camera and infrared thermal imager reduces the impact of high temperature, high humidity and strong electromagnetic interference on detection, and reduces the risk of false positives and false negatives; on the other hand, a cleaning device with sponge blocks or brushes is provided below the camera and infrared thermal imager, which can clean the dirt on the surface of the equipment in time and avoid dirt affecting the detection accuracy.

[0015] 3. Enhanced emergency response efficiency: The device is equipped with an audible and visual alarm connected to the controller. Once a hazardous material leak is detected, the alarm can be triggered quickly to remind staff to take timely action. At the same time, the controller uses an ESP32 chip with a built-in WiFi module, which can wirelessly connect to the control center via an antenna to achieve real-time transmission of detection data. This allows the control center to remotely monitor the leak situation and improve emergency decision-making and response speed.

[0016] 4. Enhanced environmental adaptability and equipment protection: The trolley wheels are equipped with a barrier with a rubber anti-collision layer on the outside, which can reduce the risk of collision damage during the movement of the trolley and adapt to the complex environment of the power plant; the front of the trolley is equipped with a headlight, which can assist in detection in low light conditions and ensure stable operation of the device around the clock. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the bottom structure of this utility model. Detailed Implementation

[0018] like Figure 1 As shown, a vision-based hazardous materials leakage detection device includes a trolley 1, a rotating pan-tilt unit 2 mounted on the trolley 1, and a horizontally positioned connecting cylinder 3 fixed on the pan-tilt unit 2. A camera 4 and an infrared thermal imager 5 are rotatably connected to both ends of the connecting cylinder 3. Motors are located at both ends of the connecting cylinder 3 to drive the camera 4 and the infrared thermal imager 5 to rotate. Using a movable trolley as the basic carrier, combined with a rotating pan-tilt unit and a motor-driven camera and infrared thermal imager, this device overcomes the positional limitations of traditional fixed monitoring equipment and allows for flexible adjustment of the detection angle. It can comprehensively cover different areas of a power plant, and through visual detection, effectively captures early visual warning information such as leakage from tank surfaces and initial smoke, solving the problems of narrow detection range and difficulty in capturing early hidden dangers associated with traditional equipment.

[0019] Preferably, the trolley 1 is equipped with a control box 6, which contains a controller. The camera 4 and the infrared thermal imager 5 are electrically connected to the input terminal of the controller. The controller in the control box can centrally receive the detection data from the camera and the infrared thermal imager, providing a core processing unit for subsequent leak detection and signal transmission. This enables the orderly collection and preliminary processing of detection data, avoiding processing delays or chaos caused by data dispersion, and providing data support for the stable operation of the device.

[0020] Preferably, the trolley 1 is equipped with an audible and visual alarm 7, which is electrically connected to the output of the controller. The audible and visual alarm is linked with the controller. Once the controller detects a hazardous material leak, it can quickly trigger the audible and visual alarm, transmitting the leak signal to on-site personnel immediately. This significantly shortens the emergency response time and solves the problem that traditional equipment cannot promptly alert personnel after detecting a leak.

[0021] Preferably, the audible and visual alarm 7 is mounted on the column 8. Mounting the audible and visual alarm on the column increases the installation height of the alarm device, making the sound and light signals spread over a wider range and less likely to be blocked by equipment, pipelines, etc. in the power plant. This also makes it easier for personnel in different locations to detect the alarm information and improves the effective transmission rate of the alarm signal.

[0022] Preferably, the controller uses an ESP32 chip with a built-in Wi-Fi module, which wirelessly connects to the control center. The Wi-Fi module is also connected to antenna 9. The ESP32 chip's built-in Wi-Fi module allows for wireless connection to the control center without additional wiring, adapting to the complex spatial environment of a power plant. The antenna enhances the Wi-Fi signal strength, ensuring the stability and real-time performance of data transmission, enabling the control center to remotely monitor the detection status and make rapid decisions.

[0023] Preferably, a cleaning device is provided below the camera 4 and the infrared thermal imager 5. The cleaning device includes a rotating motor 10, a turntable 11 at the upper end of the rotating motor 10, and a cleaning module 12 on the turntable 11. The cleaning module 12 is a sponge block or a brush. Figure 2 As shown, when the lenses of camera 4 and infrared thermal imager 5 are rotated to a vertically downward position, the cleaning device drives the turntable and cleaning module through the rotating motor, which can promptly clean the dust and stains on the surface of the camera and infrared thermal imager lenses, avoid pollutants affecting imaging accuracy, ensure the accuracy of visual inspection, and adapt to the environment of power plants where dust and stains are easily generated.

[0024] Preferably, the outer side of the wheels of the trolley 1 is provided with a barrier 13, and an anti-collision layer 14 is provided on the outer side of the barrier 13. The anti-collision layer 14 is a rubber layer. The barrier on the outer side of the wheels can provide basic protection for the wheels, and the outer rubber anti-collision layer has a buffering effect, which can reduce the damage caused by the trolley colliding with equipment, pipelines, etc. when moving in the power plant, improve the durability and operational safety of the trolley, and adapt to the complex environment of the power plant with multiple equipment and obstacles.

[0025] Preferably, the front end of the vehicle 1 is equipped with a headlight 15. The headlight at the front end of the vehicle can provide illumination in the dimly lit areas of the power plant, ensuring that the camera and infrared thermal imager can still clearly collect image data in low-light environments, achieving stable detection in all weather and all scenarios, and solving the problem of poor detection performance in low-light environments.

[0026] This invention uses a mobile trolley as its basic carrier, equipped with a rotating gimbal and a horizontally arranged connecting cylinder. The connecting cylinder is fitted with a camera and an infrared thermal imager, both driven by motors, allowing for flexible movement of the detection position and multi-dimensional adjustment of the detection angle. This enables comprehensive coverage of different areas of the power plant and efficient capture of early visual warning information. It abandons the traditional detection logic that relies on temperature, humidity, and gas sensors, adopting a visual detection method that combines a camera and an infrared thermal imager, significantly reducing interference from complex environments and minimizing false positives and false negatives. A control box containing an ESP32 chip is installed on the trolley. The chip has a built-in WiFi module and an antenna, enabling centralized processing of detection data and real-time wireless transmission to the control center, supporting remote monitoring and rapid decision-making. Furthermore, a lens cleaning device, wheel wells and rubber anti-collision layers, and front-end lights are specifically designed to ensure the device is adaptable to the complex environment of power plants with numerous obstacles, high dust levels, and variable lighting, and to operate stably.
