Abstract
Description
Technical Field
[0001] The invention relates to the technical field of detection equipment, in particular to a gas leakage detection equipment for pipeline rupture. Background Art
[0002] Pipeline inspection requires the use of visual cameras and other sensors to collect information inside the pipeline in order to determine the location of defects inside the pipe. The main detection methods are: ultrasonic detection, infrared thermal imaging detection technology and vision-based automatic detection technology. The ultrasonic detection method uses the principle of pulse reflection to detect pipeline defects. Since the energy reflected back by ultrasonic waves at different media interfaces is different, it can work in transmission media such as water and oil. Therefore, it is suitable for detecting the thickness, attenuation and defect location and size of oil pipelines; infrared thermal imaging detection method uses the heat exchange between the target and the background due to different temperatures to detect pipeline leaks, damage to the insulation layer, etc.
[0003] Leaks caused by rusted pipes are a common problem, especially in metal pipes. When the surface of the pipe rusts, the rust forms a protective layer that can mask the leak below. This can cause the detection method to fail because the rusted area can block the actual leak point, and the camera cannot clearly capture the defect, making it difficult to identify the leak. When the detection method fails and the leak is not discovered in time, it can lead to more serious safety hazards and increase the cost and complexity of maintenance and repair. Leaks cause the internal medium to come into contact with the outside air, further accelerating the corrosion of the pipe, forming a vicious cycle. Summary of the invention
