Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to a directional scanning device for nondestructive testing of pressure vessels. Background Technology

[0002] Pressure vessels are closed devices that hold gases or liquids and withstand a certain pressure. They are widely used in the petrochemical, power, and special equipment manufacturing industries. Non-destructive testing area-oriented scanning devices are used to inspect key parts to ensure that the equipment meets relevant safety standards.

[0003] A directional scanning device for non-destructive testing of pressure vessels typically includes guide rails, sliders, and rotating mechanisms. These are used to precisely control the position and trajectory of the testing probe and X-ray source, enabling directional scanning of different areas of the pressure vessel. For example, some devices use a reciprocating screw and slider to allow the testing probe to perform linear reciprocating motion on the surface of the pressure vessel, while simultaneously using a rotating mechanism to achieve circumferential rotation.

[0004] In existing technologies, directional scanning devices for non-destructive testing of pressure vessels utilize the penetrating and ionizing properties of X-rays and gamma rays to inspect pressure vessels. When rays penetrate the pressure vessel, the different degrees of absorption and attenuation due to the internal structure and defects of the vessel result in images of varying grayscale on the detector or film opposite the radiation source. By analyzing these images, it is possible to determine whether there are defects inside the vessel, such as cracks, pores, and inclusions. However, the performance of the scanning device can be affected by harsh environments such as high temperature, high pressure, humidity, and strong electromagnetic interference, leading to inaccurate test data and equipment malfunctions. Therefore, special protective measures are taken for the scanning device, using materials and components that are resistant to high temperatures, moisture, and electromagnetic interference to improve the stability and reliability of the equipment in harsh environments. However, during inspection, it is necessary to manually hold the X-ray inspection equipment and walk around the tank. Inadequate protection can easily cause significant radiation exposure to the inspection personnel, endangering their health. Utility Model Content
