Description

Technical Field

[0001] The invention relates to the technical field of composite material gas cylinder detection, in particular to an ultrasonic scanning detection device for composite material gas cylinders. Background Art

[0002] Industrial composite (carbon fiber layer and metal inner composite) gas cylinders are used as natural gas storage and transportation equipment. Glass fiber or carbon fiber is usually wrapped on the outer surface of the steel liner. The fiber layer generally bears more than half of the internal pressure load. The outer fiber is easily damaged after collision and scratching. The fiber layer is the relative weak point of the entire composite gas cylinder and the key point to ensure the safe use of the gas cylinder. Composite gas cylinders will inevitably be subjected to low-speed impacts from foreign objects during manufacturing, storage, transportation and use. The impact damage failure modes of composite structures are mainly manifested as intrusion, matrix cracking, fiber breakage, debonding cracking and stratification at the interface between fiber and matrix. In the straight section of the composite gas cylinder, the fiber breakage and matrix cracking of the winding layer first occur in the inner layer, and then develop to the outer layer.

[0003] At present, the main methods used to detect damage in fiber winding layers include infrared thermal imaging, laser shearing speckle, acoustic emission, ultrasonic guided waves, ultrasonic C-scan and digital X-ray detection. Among them, ultrasonic C-scan detection is rapidly being promoted and applied due to its advantages such as intuitive detection results, light detection equipment, pollution-free detection process and easy detection automation.

[0004] However, in practical applications, we found that the existing ultrasonic scanning detection devices for composite gas cylinders still have certain shortcomings, such as:

[0005] 1. Probe coupling problem: Since the surface of the material combined with the fiber wrapped around the surface of the gas cylinder is very rough, the ultrasonic probe cannot fit the surface of the workpiece, and the probe coupling effect is very poor, resulting in the inability to perform detection operations;

[0006] 2. Inspection efficiency: When manually inspecting the entire wrapped gas cylinder, the entire cylinder body is required to be 100% scanned. The surface area of ​​the cylinder to be inspected is large, and the arc-shaped surface requires the cylinder body to be rolled continuously during manual inspection, resulting in low inspection efficiency and time-consuming and labor-intensive.

[0007] Based on this, we proposed an ultrasonic scanning detection device for composite gas cylinders. Summary of the invention
